Description

Field of technology

The utility model generally relates to household appliances, especially medical devices, and can be used to heat various parts of the human or animal body as well as to heat various objects in field or extreme weather conditions, such as beverage containers, pockets, appliances, etc.

Prior art

A number of devices are known for heating various parts of the human body. An example is a hand-held heater for skiers consisting of an airtight container with a built-in metal disk filled with a chemical which, under normal conditions, undergoes crystallization accompanied by the development of heat. Such chemicals most often contain supersaturated solutions of certain salts.

The chemical in the container starts to generate heat from the moment of activation. For this purpose, it is necessary to push on a metal disk, which immediately starts the crystallization process accompanied by the development of heat. After complete crystallization of the chemical, the hand heater should be put into initial mode by appropriate conversion of the crystals to a liquid state. Because such a process requires heat consumption, the heater should be heated at a moderate temperature until the crystals are completely dissolved (see online store https://www.gorgany.com).

The disadvantage of such a hand warmer is that the container body has a fragile and non-ergonomic shape. It often happens that the crystallization of a chemical is activated due to negligence, even if it is not necessary. When attempting to warm the hands, the user may face a current hand heater failure because the internal chemical crystallizes and requires the hand heater to overcook to return it to the initial mode. Thus, such a hand warmer does not guarantee the possibility of providing its functions only if necessary. In addition, if the airtight container is damaged, the chemical can get on the cap or directly on the user.

Another known catalytic hand heater comprises a metal shell provided with a cover equipped with a fuel tank with a catalyst located in the inlet area. The catalyst (catalytic network) is a platinum element in the shape of a fuse. The inside of the fuse contains a steel mesh insert. The principle of operation of the catalytic hand heater is based on the flameless oxidation of highly refined fuel vapors. The catalytic converter fuse is saturated with fuel vapor, the cover is constructed with through holes intended for a permanent supply of a small volume of air to the surface of the catalytic network and the catalytic converter can be activated by a match or lighter. Upon activation, highly refined fuel vapors undergo slow oxidation accompanied by the development of heat. The catalytic hand warmer is additionally equipped with a cloth bag (see the online store https: //kovea.in .ua / catalog / katalitiche sk i c g rcl k i / V I <H P W04 S .html).

A significant advantage of such a hand heater compared to the previous model is undoubtedly the construction of the fuselage characterized by a stable ergonomic shape. However, one of the disadvantages of the analogue is that the catalytic heater requires the use of a fuel of a specific type, which should have a mandatory high purity. Any failure to do so may result in the failure of the hand warmer. In addition, as soon as the fuel runs out in the tank, a new part of the fuel should be added by pouring it into the tank, while the remnants of the previous part of the fuel must be removed. The above condition is particularly important because mixing the remnants of the previous part of the fuel with the new one significantly reduces its quality. Such manipulations caused by the use of a catalytic heater can be inconvenient and dangerous for the user. A common disadvantage of this analog and the previous embodiment is that such a hand warmer is not suitable for heating various parts of the body, thus limiting its use.

Also known is a hand pocket pocket heater with a USB connector, which is an electronic device with a rigid ergonomic housing equipped with a built-in electronic heating system, referred to as a Pebble Hand Warmer and containing a built-in extra battery, built-in flashlight and massage device. In addition, the hand warmer is equipped with a cable with a USB connection that allows energy to be accumulated from an external system during charging. Thanks to the fact that it is equipped with a built-in additional battery, this hand-held heater can be used similarly to an energy bank, the so-called power bank, for charging external electronic devices. This hand warmer provides three heating modes, see the description at https://mv.mlm planet.net.ua/katalog/bytovye_pribory/grelki_portativnye/usbgrelka_dlya_ruk_karmannaya_power_bank.html (online store https://foster.com.ua/).

One of the disadvantages of such an embodiment of the heater is that it is not suitable for heating various parts of the body, it is only limited to use for heating hands.

Furthermore, a heater is known which is formed in the form of a belt, which is suitable for performing physiotherapeutic procedures at home and consists of two layers of felt, between which a heating system is placed. It contains the heating element (or elements) and wires for connecting the heating element to an external power network. The heating element is formed as a carbon fiber characterized by sufficient plasticity and bending resistance. During connection to the external electrical network, the heating element emits infrared rays. This type of radiation heats the part of the body covered by the belt and is characterized by other benefits that are typical only for this type of radiation, including preventing traumatization or drying of the skin, facilitating blood circulation, eliminating muscle cramps, etc. (online shop https://vsevhatu.com /). One of the disadvantages of a belt-shaped heater is that it does not work independently. Due to the modern pace of life, the use of heating equipment in the constant vicinity of drawers is clearly an impractical option and unrealistic for many users.

Also known is a hand warmer with a convertible side and a fixing element provided with a belt (as a fixing element) and a heating element, the belt being designed with a pocket and fastening at both ends and the heating element being reusable and insertable into the pocket in a way to remove it from the pocket. . This heater is the closest equivalent of the applied solution. The heating element operates and radiates heat caused by a chemical reaction or the emission of microwave radiation, (see U.S. Pat. No. 5,499,401, IPC A41D 13/08 of March 19, 1996). The disadvantage of this closest equivalent solution is that it involves heating caused by a chemical reaction or emission of microwave radiation. On the one hand, heating induced by a chemical reaction is an example of standard heat transfer, because a more heated object transfers heat to a less heated object, while the previous object is heated by the energy emitted during the crystallization process. However, as noted above, the application of chemicals can be dangerous and the crystallization process can begin unexpectedly and due to user negligence. On the other hand, the inventors of this solution state that their hand warmer equipped with a convertible side and a fastening element ensures the direction caused by the emission of microwave radiation and cannot reflect it. However, it is known that microwave radiation is not completely safe for humans, and therefore the possibility of its application for long-term hand heating is questionable.

The essence of the technical solution

The aim of the presented technical solution is the development of such an independent local heating system, which on the one hand ensures safe heating and on the other hand simplicity and versatility of independent local heating system with heat transfer from the heated surface of the stable body cover combined with its implementation into the fixing structure storage element. i.e., a system that is suitable for heating not only human hands, but also other parts of the human or animal body, as well as various objects.

The stated object is achieved in that the independent local heating system comprises a fastening member designed with the possibility of inserting and removing at least one heating element, where according to the present technical solution the fastening member is constructed as a belt comprising at least one

-2 CZ 34736 UI pocket. The belt is then provided with at least one fastening element, when the heating element can be placed in one pocket or in each of the belt pockets, the heating element or each of the heating elements being formed as an electronic device with a fixed housing and built-in electric battery. it is heated and emits heat.

The claimed utility model involves the use of an electronic device with a rigid housing and a built-in electric battery as the heating element, wherein the outer surface of the housing is heated and emits heat. Accordingly, any electronic device with a rigid housing and a built-in electric battery whose outer surface of the housing is heated and emits heat can be used as the heating element, including the above-mentioned hand-held pocket heaters.

The use of an electronic device with a fixed heating element housing almost completely eliminates the possibility of accidental activation of the heating process, which often occurs when using hand warmers based on the use of supersaturated saline solutions. As with other electronic devices, the heating element is of course equipped with a switch. The heating element of an independent local heating system can thus only be activated by intentional switching on by a person.

The built-in electric battery ensures in particular the independence of the operation of the heating element and also the use of an independent local heating system in general. The electric battery provides the possibility of charging by connecting to an external energy network or an external energy source, including energy banks. In addition, in specific applications of the utility model, the design of the electric battery, as well as the heating element itself, may provide the possibility of replacing the electric battery in the heating element.

The claimed independent local heating system comprises heating by heat transfer from the heated surface of the heating element shell to the object to be heated. Heating of the casing surface is ensured thanks to the energy of the electric battery. In specific use cases, the entire outer surface of the rigid shell is not heated. The complete or partial heating of the surface of the rigid jacket of the heating element is performed with respect to the determined initial conditions.

In addition, thanks to the use of an electronic device as a heating element, the possibility of regulating the heating level of this element or of each of these elements is ensured. Thus, for example, each heating element may have three, four, five or a different number of heating levels. Accordingly, the heating levels of the claimed independent system will be determined by the heating levels of the heating element or each of the heating elements in combination with the number and arrangement of heating elements throughout the independent local heating system.

According to the present utility model, "belt" means any elongate element designed to be attached to the human or animal body as well as various objects such as beverage containers, handheld devices, etc. The belt is thus an elongate element designed with two ends that can be connected to each other. . In most embodiments of the utility pattern, the belt is made of an elastic material to provide a firm attachment of the independent heating system along with the closest possible contact between the heating element and the heated surface. Thus, it will be appreciated that both ends may be provided with any anchoring and adjusting elements, including, but not limited to, various buckles, straps, studs, buckles, fastex Velcro fasteners, and length regulators. In special embodiments of the utility model, the ends of the belt may be joined by binding.

As an elongate element, the belt is designed to control a heated object, which is a versatile system that can be applied to the human or animal body or to any object to be heated. This component, which is integrated into an independent local heating system, ensures the versatility of the entire independent local heating system. In particular cases of utility model implementation, the independent local heating system strip may additionally include controllers of various types, such as frames, clips, etc., which are another tool to ensure the versatility of the claimed independent local heating system.

-3 CZ 34736 UI

The essence of the utility model is that the belt is provided with at least one pocket, the heating element being placed in this pocket or in each of these pockets. However, it is clear that a technical solution comprising a fastening member designed with the possibility of inserting and removing at least one heating element can be functionally realized using other equivalent elements. These options include, but are not limited to, inserting a heating element into a bag or inserting each of the heating elements into bags, in which case the belt pocket is designed to be removable, and securing the bag or each of the bags to the fastening belt. In both cases, whether the belt is equipped with pockets or bags, the possibility of adjusting and removing the heating element from the belt is ensured.

The exact construction of the belt, i.e. its width and length, overall dimensions, number of pockets and their size, number and type of fasteners, etc., thus depends on setting the exact initial operating conditions of the heating element or each of the heating elements placed in the belt pocket. It is clear that the number of heating elements or the number of pockets in the strip and their arrangement depend on the exact initial conditions, in particular on the area of the surface to be heated.

For example, in the case where it is necessary to heat a person's hand or chest, in the first case the belt will obviously have a smaller length and width and the availability of one pocket with a heating element in the belt will suffice. Accordingly, heating the human chest requires the use of a belt of greater width and length and with respect to the area to be heated, when the belt may for example comprise two, three or four pockets, each of which is provided internally with a heating element. For this reason, the simplicity and versatility of the design of an independent local heating system allows a wide range of body parts to be heated where necessary. In addition, the simplicity and versatility of the design of the independent local heating system allows its use for heating not only human but also animal body parts, as well as various objects. In addition, another function of the technical solution is that the heating element can serve as a power source for electronic devices, for example in extreme conditions and when charging is available, the heating element of an independent local heating system can be used as a power bank for handheld devices.

The belt 1 is thus equipped with one pocket 2 (see Fig. 2a), two pockets 2 (see Figs. 2b and 2c) and four pockets 2 (see Fig. 2d).

In specific embodiments of the technical solution, the rigid shell 4 of the heating element 3 and the strip 1 can be made of an antibacterial material. For a specific application, the strip 1 in the area of the location of the heating element 3 can be designed to provide only a specified transfer of heat collected from the network or other sources. In specific cases, the strip 1 in the area of the location of the heating element 3 may be designed to provide limited heat transfer, for example it is equipped with a synthetic cooler, but is not limited to this purpose only. In specific cases, the heating element 3 may be stored in a pocket 2 in a package made of various materials, such as cotton, rayon, polyester, etc., to ensure limited heat transfer, but these materials are not the only possible limiting examples. Furthermore, the pocket 2 can be designed as a removable, for example in the form of a removable case, as can be seen from Fig. 2e). In this embodiment, the side wall of the pocket 2 serving for attachment to the belt 1 and the respective surface of the belt 1 are provided with at least one connecting element 14. The connecting element 14 or each of the connecting elements 14 can be formed as a button, label, buckle, lock etc. The pocket 2 or each of the pockets 2 may be made of the same material as the belt 1 or of different materials. Separate heating elements 3 are arranged in each of the pockets 2. In this case, the heating element 3 is stored in the pocket 2 in such a way that it is easy to remove and then stored so that neither the heating element 3 nor the pocket 2 itself is removed during removal and / or storage damaged.

The local heating provided by the function of the applied independent system requires heating the outer surface of the rigid shell 4 after activating the heating element 3 and transferring heat in classical form from a more heated object to a less heated object, i.e. from the outer surface of the shell 4 to the area of the object being heated. It is further apparent that the heat transfer occurs through the side of the pocket 2 which is located closer to the heated area. The heating of the surface of the rigid casing 4 is provided by energy from the electric battery 5.

The technical solution mainly ensures heating of the entire outer surface of the rigid jacket 4. Thanks to the established "microclimate" under clothing, it is therefore possible to quickly achieve a pleasant warming of the whole body by an independent local back warming system, for example by arranging around the waist.
