Description

Technical Field

[0001] The invention relates to a heat release device which generates heat by utilizing non-combustion exothermic chemical reaction. Background Art

[0002] In winter, for the convenience of keeping warm, people will use a heating device that uses non-combustion exothermic chemical reactions to generate heat. Most of the devices are in the shape of bags. When the composite material in the device comes into contact with the air, it can produce an exothermic reaction with the oxygen therein, thereby generating heat for heating. It is easy to carry and generates heat stably.

[0003] However, most of the heat release devices currently on the market are equipped with an airtight plastic sealed outer bag outside the non-woven bag of the composition. When in use, the sealed outer bag is torn off, and the composition in the non-woven bag is immediately exposed to the air and reacts with oxygen to generate heat until the reaction is completed. Since the non-woven bag has good air permeability, the disadvantage of this device is that it cannot control the reaction process of the exothermic reaction between the composition and oxygen. Once the reaction starts, even if heating is not required, the reaction cannot be stopped and can only release heat until the reaction is completed, thereby causing heat waste. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a heat release device which can timely control the reaction process of the composition and oxygen and more effectively utilize the heat generated by the exothermic reaction in order to overcome the defect in the prior art that the reaction process of the composition and air and the exothermic reaction with oxygen cannot be controlled, thereby causing heat waste.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a heat release device, including an outer bag body and an inner bag body, the inner bag body is arranged in the outer bag body, and an air intake structure and an exhaust structure are arranged on the surface of the outer bag body, which are used to control the gas entering and exiting the outer bag body, thereby regulating the progress of the exothermic reaction. A sealing member is also arranged at the opening of the outer bag body, which is used to seal the outer bag body. The inner bag body contains a composition that can undergo an exothermic reaction with oxygen, and the surface of the inner bag body is provided with pores that can contact with air, which are used for the composition to contact with oxygen in the air to undergo an exothermic reaction.

[0006] Furthermore, the inner wall of the outer bag body is provided with detachable parts which cooperate with the detachable parts of the inner bag body so that the inner bag body can be detachably fixed in the outer bag body.

[0007] Furthermore, the air intake structure is a one-way exhaust structure including a lower cover body and an upper cover body that can close the lower cover body to prevent air from entering the inner part of the outer bag body, the lower cover body includes two L-shaped columns that are relatively arranged to form an opening and a connecting plate connecting them together, wherein the L-shaped column faces the outer side of the outer bag body, the connecting plate is connected to the outer bag body, and an air hole is provided on the connecting plate. The lower cover body also includes a spring and a blocking component, the spring is connected to the blocking component and fixed in the center of the connecting plate, and is used to block the opening formed by the L-shaped column. When air is taken in, the upper cover body is removed from the lower cover body, and the elastic action of the compressed outer bag body causes the internal space of the outer bag body to expand, the air pressure in the bag is reduced, and the air pressure outside the bag compresses the spring to open the blocking component, and the air enters the inner part of the outer bag body through the air hole.

[0008] Furthermore, the exhaust structure is a lower cover body with a one-way exhaust structure, and the opening formed by two L-shaped columns arranged opposite to each other in the lower cover body faces the inner side of the outer bag body. The connecting plate is connected to the outer bag body. When exhausting, the outer bag body is squeezed, and the pressurized gas pressure inside compresses the spring to open the blocking component, and the gas is discharged to the outside of the outer bag body through the air hole.

DETAILED DESCRIPTION

[0016] The present invention will now be further described in conjunction with the accompanying drawings, which are all simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] See also Figure 1 It is a heat release device structure, including an outer bag body 1 and an inner bag body 2 (not shown in the figure). The surface of the outer bag body 1 is provided with an air intake structure 12 and an exhaust structure 13, both of which are one-way exhaust structures. A sealing member 4 is also provided at the opening of the outer bag body 1 for sealing the outer bag body 1.

[0018] See also Figure 2 It is an air intake structure 12, including an upper cover body 30 and a lower cover body 31. When air is taken in, the upper cover body 30 is removed from the lower cover body 31, and the elastic action of the compressed outer bag body 1 causes the internal space of the outer bag body 1 to expand, and the air pressure inside the bag is reduced. The air pressure outside the bag compresses the spring 321 to open the blocking component, and the air enters the interior of the outer bag body 1 through the air hole 313.

[0019] See also Figure 3 This is the first embodiment of the lower cover body 31, including two L-shaped columns 311 and a connecting plate 312 connecting them together. The connecting plate 312 is provided with an air hole 313. The connecting plate 312 is connected to the inner wall of the outer bag body 1. The two L-shaped columns 311 are arranged opposite to each other to form an opening. The spring 321 is connected to a blocking component such as a sphere 322 and is fixed in the center through the connecting plate 312. The sphere 322 can be used to block the opening. When in use, the pressure compresses the spring 321 to open the sphere 322, and the gas can enter or discharge the outer bag body 1.

[0020] See also Figure 4It is a second embodiment of the lower cover body 31 of the one-way exhaust structure, including two L-shaped columns 311 and a connecting plate 312 connecting them together. The connecting plate 312 is provided with an air hole 313. The connecting plate 312 is connected to the inner wall of the outer bag body 1. The two L-shaped columns 311 are arranged opposite to each other to form an opening. The spring 321 is connected to a blocking component such as a cuboid 323 and is fixed in the center through the connecting plate 312. The cuboid 323 can be used to block the opening. When in use, the pressure compresses the spring 321 to open the cuboid 323, and the gas can enter or discharge the outer bag body 1.

[0021] See also Figure 2-4 To further understand the specific implementation method of gas entering and exiting the outer bag body 1: when heating is needed, air needs to enter the outer bag body 1 so that the composition 21 in the inner bag body 2 reacts with oxygen in an exothermic reaction. At this time, the upper cover body 30 is removed from the lower cover body 31, and the elastic action of the compressed outer bag body 1 causes the internal space of the outer bag body 1 to expand, and the air pressure inside the bag decreases. The air pressure outside the bag compresses the spring 321 to open the blocking component, and the air enters the interior of the outer bag body 1 through the air hole 313, and the exothermic reaction begins, thereby achieving a heating effect.

[0022] When heating is not needed, the air needs to be exhausted from the outer bag body 1. When exhausting, the outer bag body 1 is squeezed, and the pressurized gas inside it generates pressure to compress the spring 321 to open the blocking component, and the gas is discharged to the outside of the outer bag body 1 through the air hole 313. At this time, the composition 21 in the inner bag body 2 has no contact with the air and cannot react with oxygen to produce an exothermic reaction, so that the exothermic reaction stops until heating is needed and the upper cover body 30 of the air intake structure 12 is opened.

[0023] See also Figure 5 It is a sealing member 4 structure, fixed at the opening of the outer bag body 1, including a first clamping plate 41 and a second clamping plate 42 arranged opposite to each other, the first clamping plate 41 and the second clamping plate 42 are movably connected at the rear ends thereof 43, and the contact surfaces of the first clamping plate 41 and the second clamping plate 42 are provided with a clamping structure to seal the outer bag body 1, and the clamping structure of the first clamping plate 41 and the second clamping plate 42 includes a groove 411 extending from the rear end to the front end of the first clamping plate 41, and a flange 421 corresponding to the second clamping plate 42 and used in conjunction therewith, and when the two clamps are closed, the flange 421 is embedded in the groove 411 to seal the outer bag body 1.

[0024] See also Figure 6It is a cross-sectional view of a heat release device, comprising an outer bag body 1 and an inner bag body 2. The inner bag body 2 contains a composition 21 that can react exothermically with oxygen. The composition 21 includes: activated carbon, iron powder, salt, vermiculite, potassium permanganate, copper sulfate, and aluminum powder. A plurality of pores 22 in contact with air are provided on the surface of the inner bag body 2 for the composition 21 to react exothermically with oxygen in the air. A detachable component 11 connected to the inner bag body 2 is provided on the inner wall of the outer bag body 1. The inner bag body 2 is provided with a detachable component 23 used in conjunction with the outer bag body 1 for detachably connecting to the outer bag body 1.
