How was the hot water bottle invented? 2022/4/11

The warm things that the ancient Chinese put in the quilt are also more sophisticated. Because the main purpose is to warm the feet, they are called "foot stoves". This is a flat copper or tin bottle filled with hot water that can be placed under a quilt to warm your feet, similar to a modern hot water bottle.There are also many other names for the foot stove, such as the foot woman, the warm foot bottle, the soup woman and the soup woman. The name of Madam Tang is very interesting, and it began in the Song Dynasty. Ancient people liked to give anthropomorphic names to some common utensils.Since the beginning of human beings, protection from the cold has been an indispensable part of survival. When people live in houses and have beds and quilts, they begin to try to put things in the quilt to keep warm. Three hundred years ago, some people in France used hot water in iron bottles to warm their feet. Some people use stones as containers to warm their feet with water, and the effect can be imagined. In the 17th century, Europeans used pottery utensils to fill hot water as a thermal tool, so the hot water bottle was called "Hot Water Bottle" in English, which mainly appeared in the royal family and aristocracy at that time.After the Age of Navigation, Europe had a large number of colonies rich in rubber, and the rubber trade continued. This lightweight and inexpensive material quickly became the raw material for hot water bottles. In 1903, a Croatian engineer invented and patented the first rubber hot water bottle. Until now, the technology of rubber hot water bottle is still used, which can be described as timeless.The engineer, Eduard Penkala, was born in 1871 and died in 1922. Although he is not famous, he is a veritable inventor. In addition to the hot water bottle, he has more than 80 invention patents, including the mechanical pencil, the prototype of the mechanical pencil, and a fountain pen that uses solid ink - so he is also a passer-by in the birth of the ballpoint pen. His joint venture pen factory is said to still exist today. Among other things, he started a chemical manufacturing company, invented a detergent and an anode battery. He even ventured into aviation, being the designer and maker of Croatia's first monoplane. Of course, the rubber hot water bottle was definitely the company's most important invention.At first, rubber hot water bottles were a medical resource and were mainly used for hot compresses. It was Italian tire maker Pirelli who promoted the hot water bottle to the civilian sector. Does this name look familiar? Yes, the Chinese translation is Pirelli, the long-term sponsor of Serie A Inter Milan. It promoted the rubber hot water bottle as a fashionable way of life, which quickly caused a craze.When the hot water bottle entered China, the first stop was of course Shanghai, the No. 1 city in the Far East. At that time, global brand products could be seen in Shanghai. Hollywood movies would definitely land in Shanghai within a month of their release in the United States. Hot water bottles were also introduced to Shanghai as part of Western-style life. After 1949, rubber hot water bags entered thousands of households and became a must-have for every household.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......

Is the PVC hot water bottle water injection mode correct? 2022/4/2

It is also important to use hot water bottles to use hot water bottles. Xiaobian teaches you to properly give PVC hot water bottles.1. Measure the water temperature with a water temperature meter, generally 60 to 70 ° C.2. Infoil hot water into the hot water bottle, 1/2 or 2/3.3. Place the hot water bag flat, drive it in the bag, tighten the hot water bottle plug and dry.4. Pour the hot water bottle, check if there is no water leak (without leakage), load the bag, tighten the socket, put it on the desired part.5. When the hot water bottle is not in use, the water is dried, and the drout is dried. After blowing into the air, tighten the plug, and put the cool place.6. Take the hot water bottle set, clean, dry and ready.Winter PVC hot water bag warm effect is not very good, add a little salt to try it.Using a PVC hot water bottle, simply add a certain salt in hot water can increase the heat preservation effect and time of the hot water bag. It is to be reminded that the salt concentration is large, the better the heat preservation, but the salt water has solubility, and it is not necessary. Each time you use a hot water bottle, you only need to heat the brine, reuse it, or reach the insulation effect.The principle is that after adding salting in hot water, the density of water will rise, and the salt water is larger than the water, and the salt water is slower than water. Therefore, the hot water bottle insulation effect and time is better. However, it is possible to mention that the salt water is solubilized, the larger the saline concentration, the better the heat preservation, and only a small amount of salt is not obvious in hot water. Moreover, each hot water is added to the salt, so the PVC hot water bottle will only heat the saline, reuse, and reach the insulation effect.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......

For example, when the patient is sprained or straamed, the doctor will apply ice as part of the treatment plan. Clinical studies have found that intra-injured parts can be 5 to 15 minutes, which can reduce the epidermis temperature to 13 ° C, which can affect the nerve of the damaged site, slow down the pain signal, thereby relieve pain. Of course, it is also possible to play a role from another way, and animal experiments show that the use of ice applications can alleviate inflammation generated after injury. Chris Bleakley, a sports medical researcher in Alst University, Northern Ireland, said this method can reduce the activity of the in vivo system, reducing the number of white blood cells transferred to the injury. After intense exercise, there is a large-area muscle fiber and soft tissue strain, full body ice, or fast cooling can slow down the passage of the pain signal, or make the temperature of the soft tissue low enough to alleviate inflammation!After listening to the introduction of Xiaobian, I believe that everyone will have a new cognition of cold water sack.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......

The disadvantages of using a hot water bottle, everyone should pay attention 2022/3/21

Tips:Low-temperature scald from a hot water bottle refers to a scald caused by prolonged contact with a heat source that is not too hot. Note: The heat sources such as hot water bottle and warm baby will not feel hot to the touch, but will only feel very warm. However, prolonged contact can cause damage to the skin and subcutaneous tissue. Studies have shown that if the heat source temperature exceeds 44 ℃, it may cause low temperature burns. Exposure to a heat source at 70°C for more than one minute and a heat source at about 60°C for more than five minutes may also cause burns. The heating temperature of the warm baby can exceed 60 ℃, the working temperature of the electric hot water bottle is above 70 ℃, and the surface temperature of the hot water bottle filled with boiling water is even more than 80 ℃, which may cause low temperature burns.People with insensitive or abnormal skin sensation, such as the elderly, children, diabetic patients with neuropathy and stroke, should not blindly apply hot compresses. If you need a hot compress, you must pay attention to controlling the temperature of the hot water bottle, otherwise it will be easy to burn. If the skin has ulceration or skin disease, it is necessary to avoid hot compresses on the surface of the skin lesions to prevent infection or irritation of the skin disease and aggravate symptoms. In addition, in the early stage of acute soft tissue injuries such as sprains and strains, there is blood stasis under the skin, and hot compresses should not be used within 24-48 hours of using a hot water bottle, otherwise local swelling will be aggravated. Hot compresses are mainly for cold symptoms, so patients with warm symptoms should not apply hot compresses. This group of people often shows that they are easy to get angry, especially afraid of heat, or accompanied by bad breath, constipation, and women also have menorrhagia and so on.The temperature of the hot compress of the hot water bottle should not be too high, usually 40-50 degrees Celsius, and the hot compress is about 20 minutes. If applying heat to delicate areas of skin, the temperature needs to be lower. At the same time, it is necessary to avoid fixing hot compresses on one part for a long time, otherwise it is easy to cause burns. The most common one is the improper use of hot water bottles to cause skin burns.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......

What should I do if the electric hot water belt is not hot? 2022/3/21

The hot water bottle is a heating tool that we often use in cold winter. The more convenient hot water bottle has an electric hot water bottle, so today I will mainly introduce the reasons why the electric hot water bottle is not hot and the solution. Before understanding this, I will give you a detailed introduction to the electric hot water bottle. , so that you can choose the electric hot water bottle correctly in the process of purchase and use.How electric hot water bottle worksThe working principle of the electrode type electric hot water bottle is improved on the basis of the solid electric heating cake. Under normal circumstances, when the temperature of the liquid in the bag reaches 65 degrees, the thermostat will automatically cut off the circuit and stop heating.Electric hot water bottle classification1. If the electric hot water bottle is an electrode type, it is very unsafe. It relies on electrode heating. During the heating process, the internal solution is charged, and the safety depends on the external thermostat and the human eye (you read that right, the electrode type electric hot water bottle is placed The gas is relatively frequent, if you don’t let it out, it will be lively). This kind of electric hot water bottle has actually been banned by the state.2. The electric heating wire type and the electric mattress are actually the same principle, but they only heat the medium with a large specific heat such as water. Because the whole process is insulated and the temperature is controllable, it is much safer than the electrode type.What should I do if the hot water bottle is not hot? What should we do?1. The gas inside must be released, and remember to use barrel-shaped pure water, otherwise, if the water quality is too hard, the electric hot water bottle will be heated unevenly or even explode.2. The water can be replaced with pure water. The water injection needs to be successful at one time, because it contains heating powder, and the poured water will lead to the failure of heating! The non-exchangeable electric hot water bottle cannot change the water. If it leaks, I suggest you don't use it.3. One kind of hot water bottle is that the manufacturer has filled it with conductive liquid, and it can be used directly after buying it. There is also one that is not filled with water when it is purchased, but a powder (iron powder or ferrite) has been put in it. If you need to fill it with water, the effect is the same. Therefore, the liquid in the bag cannot be replaced with tap water, otherwise it will not heat up.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......

Hazards of long-term use of electric hot water bottles 2022/3/14

Winter warm hot water bottle is the first to rush, many people will use electric hot water bottles for a long time, then what hazards will be used for long-term use of electric water sacks, let's pay attention.First, low temperature burnsIf the electric hot water bottle is improper, it is easy to cause low temperature iron. The skin is in contact with the low temperature heat source, which will gradually develop into a deep layer of the leather and the undercuts. Low-temperature burns pain is not very obvious, only redness, blisters, peeling or whitening on the skin, the area is not big, but the wound is deeply serious, and even if the deep tissue necrosis, if it is improper, it will have fallen. I can't heal for a long time.In order to avoid this damage, the heated temperature can be appropriately controlled when using an electric water bag. After the heating is completed, an envelope or a layer of towels can be added outside of the electric water bag, so that the electric hot water bottle does not directly contact the user's skin.Second, induced dermatitisIf the electric hot water bottle is used for too long, it is easy to induce skin. This is because long-term use of electric water bags will cause excessive loss in the skin, thus become dry, itching, leading to skin allergies, induces dermatitis. Especially for elderly or dry skin should pay special attention. Therefore, pay attention to the moisture when using an electric water bag.Third, an explosionSince there is a media report to the incident of the electric water salad, many people feel that they have a balance, and it is not awkward when using the electric water bag. The electric hot water bottle does have a certain explosive hidden danger, but as long as it is used, and the preferred business is preferred, large business can be avoided. At the same time, remember to buy electric heating wire electric water bags, do not purchase electrode hot water bottles. The electrolyte solution in the electrode hot water bottle is in a state of charge, and therefore, once the leakage occurs, there is an electric shock risk; in addition, since the electrode is directly directly and liquid contact, the electrical energy conversion is high, and there is no temperature control device, after power is energized. The hot water bottle is expanded and is prone to explosion. In contrast, the heat generating body of the electric wire type hot water bag does not contact the liquid, and the coil is also separated by the insulator and liquid to ensure safety.In addition, when you sleep at night, your body can't keep your hot water bottle, prevent the hot water bottle when you turn over, so that the hot water in your hot water bottle is booming. Therefore, as long as the electric hot water bottle is properly used, the three damage mentioned above, the electric water bag is still the magic weapon of our winter.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle,cervical spine hot water bag, plush hot water bottle.......
