Description

Technical Field

[0001] This utility model relates to the field of hand warmer technology, and in particular to a temperature-regulating hand warmer. Background Technology

[0002] A hand warmer, also known as a pocket warmer, is a small everyday item placed in one's bosom for warmth. Commonly used materials include copper, copper alloys, iron, and zinc alloys. Its core component is the combustion element; different types of combustion elements utilize different principles to generate heat without an open flame.

[0003] The hand warmer disclosed in Chinese Utility Model Patent Application Publication CN202267133U, although its heating method is a smoldering method and there is no danger in its use, and it can be used as both a fragrance and a mosquito repellent, making it more convenient to use, does not solve the problems of the hand warmer being damaged when the fiber cotton comes into contact with the burning element due to shaking during daily use, the inability to adjust the temperature according to personal preference, and the easy deformation of the hand warmer cover when impacted or squeezed, which not only affects the appearance but also the normal use of the hand warmer. The existing hand warmers usually have multiple air inlets, which leads to the air inside the hand warmer being relatively disordered, thus preventing the burning element from heating up properly. Therefore, this application provides a temperature-adjustable hand warmer to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a temperature-regulating hand warmer to solve the problems of existing hand warmers where the fiber cotton comes into contact with the burning component when shaken, causing damage to the burning component, and the hand warmer cover being easily deformed by impact, affecting its appearance.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A temperature-regulating hand warmer includes a hand warmer body, an oil and gas evaporation hole fixedly connected to the upper surface of the hand warmer body, a limit block fixedly connected to one side of the oil and gas evaporation hole, and a fixing block fixedly connected to one side of the hand warmer body.

[0007] A fixed shaft seat is fixedly connected to the other side of the oil and gas evaporation hole. A fixed seat is rotatably connected inside the fixed shaft seat. A protective net is fixedly connected to one side of the fixed seat. A protrusion is fixedly connected to one side of the protective net. A limiting seat is fixedly connected to one side of the protrusion. A limiting rod is rotatably connected inside the limiting seat. A limiting plate is fixedly connected to the lower surface of the limiting rod. A combustion cover is snapped onto the surface of the oil and gas evaporation hole. A baffle is snapped onto the inside of the combustion cover. A combustion element is snapped onto the inside of the combustion cover. A combustion hole is opened on the upper surface of the combustion cover. A pocket stove cover plate is snapped onto the surface of the pocket stove body. A connecting block is fixedly connected to the inside of the pocket stove cover plate.

[0008] Optionally, the oil and gas evaporation hole is located on the upper surface of the hand warmer body near the middle, and the fixing block is located on one side of the hand warmer body near the upper part.

[0009] Optionally, the upper surface of the hand warmer body is provided with a step, and the area of ​​the upper surface of the step is slightly smaller than the area of ​​the upper surface of the hand warmer body.

[0010] Optionally, the protective net is located above the oil and gas evaporation hole, and the limiting plate is located below the limiting block.

[0011] Optionally, the combustion element is provided with a connecting strip on one side, and the combustion cover is provided with a connecting groove on one side, wherein the size of the connecting strip is adapted to the size of the connecting groove.

[0012] Optionally, the number of combustion holes is two, with the two combustion holes located on the upper surface of the combustion cover near both sides, and the combustion element located on the upper part of the baffle.

[0013] Optionally, a through groove is provided on one side of the combustion cover, and a connecting block is provided on one side of the baffle, the size of which is adapted to the size of the through groove.

[0014] Optionally, an air inlet is provided on one side of the hand warmer cover, an air inlet pipe is fixedly connected inside the hand warmer cover, a central hole is provided on one side of the air inlet pipe, and an auxiliary hole is provided on one side of the hand warmer cover. The air inlet is located near the lower part of one side of the hand warmer cover, and the auxiliary hole is located near the upper part of one side of the hand warmer cover.

[0015] Optionally, the number of air inlets is three, and all three air inlets are connected to the air inlet pipe.

[0016] Optionally, the upper surface of the hand warmer cover is provided with a vent hole, and a heat-conducting structure is fixedly connected inside the hand warmer cover, the heat-conducting structure being located on the inner side of the hand warmer cover near the upper part.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting up a protective net, fiber cotton is placed inside the hand warmer body through the oil and gas evaporation hole. Then, an appropriate amount of fuel oil is poured into the hand warmer body, allowing the fiber cotton to fully absorb the fuel oil. By rotating the fixed shaft seat, the protective net is rotated counterclockwise to the upper part of the oil and gas evaporation hole. Then, by rotating the limiting rod, the limiting plate is positioned below the limiting block, thus fixing the protective net. This effectively intercepts and protects the fiber cotton inside the hand warmer body, reducing the possibility of the fiber cotton coming into contact with the combustion element and causing damage to the combustion element during daily use due to shaking of the hand warmer. It achieves the effect of preventing the fiber cotton from contacting the combustion element when using the hand warmer. At the same time, when adding dye oil, rotating the limiting rod separates the limiting plate from the limiting block, allowing the protective net to be opened for dye oil addition.

[0019] By setting up a combustion cover, placing the burner inside, and connecting the baffle to the lower through slot, the hand warmer can be used at a lower temperature. For hand warmers requiring a higher temperature, a second burner can be placed inside the combustion cover, connected to the upper through slot, and then connected to the lower through slot, resulting in a higher operating temperature. This reduces the inability to adjust the temperature according to personal preference. It achieves the effect of increasing the volume of the burner by adding two burners to increase the catalytic reaction efficiency when a higher temperature is desired, thus raising the hand warmer temperature; conversely, reducing the volume of the burner by installing a single burner to lower the temperature when a lower temperature is desired.

[0020] By incorporating a heat-conducting structure, the heated area of ​​the hand warmer cover is increased. Simultaneously, the heat-conducting structure supports the interior of the cover, reducing the risk of deformation caused by impacts or pressure, which is common in hollow hand warmers. This not only affects aesthetics but also the normal use of the hand warmer. The heat-conducting structure supports the interior of the cover, reducing deformation. Furthermore, the increased heated area allows for better heat absorption. Outside air enters the air inlet pipe through the air inlet and is then directly supplied to the surface of the burning component through the concentrator. The exchange of hot and cold air within the hand warmer is facilitated by auxiliary and exhaust ports. The contact between the connecting and fixing blocks ensures a better fit between the cover and the hand warmer body. This addresses the issue of multiple air inlets in traditional hand warmers causing internal air turbulence and hindering proper heating of the burning component. By collecting and concentrating incoming outside air on the surface of the burning component, better heating is achieved. Attached Figure Description

[0036] like Figures 1-4As shown, an embodiment of this utility model provides a temperature-regulating pocket warmer, including a pocket warmer body 1. An oil vapor evaporation hole 2 is fixedly connected to the upper surface of the pocket warmer body 1. A step is provided on the upper surface of the pocket warmer body 1, the area of ​​the step's upper surface being slightly smaller than the area of ​​the upper surface of the pocket warmer body 1. A limiting block 3 is fixedly connected to one side of the oil vapor evaporation hole 2, and a fixing block 4 is fixedly connected to one side of the pocket warmer body 1. The oil vapor evaporation hole 2 is located near the middle of the upper surface of the pocket warmer body 1, and the fixing block 4 is located near the upper part of one side of the pocket warmer body 1. A fixing bearing 5 is fixedly connected to the other side of the oil vapor evaporation hole 2. A fixing seat 6 is rotatably connected inside the fixing bearing 5. A protective net 7 is fixedly connected to one side of the fixing seat 6, and a protrusion 8 is fixedly connected to one side of the protective net 7. A limiting seat 9 is fixedly connected to one side of the protrusion 8, and a limiting rod 10 is rotatably connected inside the limiting seat 9. A limiting plate 11 is fixedly connected to the lower surface of the positioning rod 10. The protective net 7 is located above the oil and gas evaporation hole 2. The limiting plate 11 is located below the limiting block 3. A combustion cover 12 is snapped onto the surface of the oil and gas evaporation hole 2. A baffle 13 is snapped onto the inside of the combustion cover 12. A through groove is provided on one side of the combustion cover 12. There are two through grooves. A connecting block is provided on one side of the baffle 13. The size of the connecting block is adapted to the size of the through groove. A combustion element 14 is snapped onto the inside of the combustion cover 12. A connecting strip is provided on one side of the combustion element 14. A connecting groove is provided on one side of the combustion cover 12. There are two connecting grooves. The size of the connecting strip is adapted to the size of the connecting groove. A combustion hole 15 is opened on the upper surface of the combustion cover 12. There are two combustion holes 15. The two combustion holes 15 are located on the upper surface of the combustion cover 12 near the two sides. The combustion element 14 is located above the baffle 13.

[0037] By inserting fiber cotton into the interior of the hand warmer body 1 through the oil vapor evaporation hole 2, and then filling the hand warmer body 1 with an appropriate amount of fuel oil, the fiber cotton fully absorbs the fuel oil. Then, by rotating the fixed shaft seat 5, the protective net 7 rotates counterclockwise to the upper part of the oil vapor evaporation hole 2. Finally, by rotating the limiting rod 10, the limiting plate 11 is positioned below the limiting block 3, thus fixing the protective net 7. This effectively intercepts and protects the fiber cotton inside the hand warmer body 1, reducing the risk of damage to the burner 14 due to contact between the fiber cotton and the burner 14 caused by shaking the hand warmer during daily use. The protective net 7 prevents the fiber cotton from contacting the burner 14 during use. Simultaneously, by rotating the limiting rod 10, the limiting plate 11 is separated from the limiting block 3, allowing the protective net 7 to be opened for adding the burner oil. This method is particularly useful when a lower temperature is required in hand warmers. When the hand warmer is in use, the burning element 14 is placed inside the burning cover 12, and the baffle 13 is connected to the through groove near the bottom, so that the hand warmer is used at a lower temperature. When a hand warmer requires a higher temperature, the burning element 14 is placed inside the burning cover 12, the baffle 13 is connected to the through groove near the top, and a second burning element 14 is placed inside the burning cover 12, and the second baffle 13 is connected to the through groove near the bottom, so that the hand warmer is used at a higher temperature. This reduces the situation where the hand warmer cannot be adjusted according to personal preference. It achieves the effect that when a higher temperature is desired, the volume of the burning element 14 is increased by adding two burning elements 14, which affects the efficiency of its catalytic reaction and thus increases the temperature of the hand warmer. When a lower temperature is desired, the volume of the burning element 14 is reduced by installing one burning element 14, thus reducing the temperature of the hand warmer.

[0038] like Figure 5 and Figure 6 As shown, a pocket stove cover plate 16 is snapped onto the surface of the pocket stove body 1. A connecting block 601 is fixedly connected inside the pocket stove cover plate 16. An air inlet 17 is opened on one side of the pocket stove cover plate 16. An air inlet pipe 18 is fixedly connected inside the pocket stove cover plate 16. There are three air inlets 17, and all three air inlets 17 are connected to the air inlet pipe 18. A concentration hole 19 is opened on one side of the air inlet pipe 18. An auxiliary hole 20 is opened on one side of the pocket stove cover plate 16. The air inlet 17 is located near the lower part of one side of the pocket stove cover plate 16, and the auxiliary hole 20 is located near the upper part of one side of the pocket stove cover plate 16. An air outlet 21 is opened on the upper surface of the pocket stove cover plate 16. A heat-conducting structure 22 is fixedly connected inside the pocket stove cover plate 16. The heat-conducting structure 22 is located near the upper part of the inner side of the pocket stove cover plate 16.

[0039] The heat-conducting structure 22 increases the heat-receiving area of ​​the hand warmer cover 16. Simultaneously, because the heat-conducting structure 22 supports the interior of the hand warmer cover 16, it reduces the risk of deformation caused by impacts or pressure, which is common due to the hollow interior of the cover 16. This deformation not only affects the aesthetics but also the normal use of the hand warmer. The heat-conducting structure 22 effectively reduces deformation by supporting the interior of the cover 16. Furthermore, the increased heat-receiving area allows the hand warmer to better absorb heat. Outside air enters through the air inlet. Air 17 enters the air inlet pipe 18 and is then directly supplied to the surface of the burner 14 through the concentrating hole 19. At the same time, the exchange of hot and cold air inside the pocket burner is completed through the auxiliary hole 20 and the air outlet 21. When the connecting block 601 and the fixing block 4 are in contact, the pocket burner cover plate 16 and the pocket burner body 1 are better engaged. This reduces the situation where the existing pocket burners usually have multiple air inlets 17, which leads to the air inside the pocket burner being more disordered and thus the burner 14 cannot heat up better. This achieves the effect of collecting the air entering from the outside and concentrating it on the surface of the burner 14, thereby enabling it to heat up better.

[0040] The working principle of this utility model is as follows: First, fiber cotton is placed into the interior of the hand warmer body 1 through the oil and gas evaporation hole 2. Then, an appropriate amount of fuel oil is poured into the hand warmer body 1, allowing the fiber cotton to fully absorb the fuel oil. The protective net 7 intercepts and protects the fiber cotton inside the hand warmer body 1. When a lower temperature is required, the burner element 14 is placed inside the burner cover 12, and the baffle 13 is connected to the through groove near the lower part, thus keeping the hand warmer at a lower temperature during use. When a higher temperature is required, the burner element 14 is placed inside the burner cover 12, and the baffle 13 is connected to the through groove near the upper part. Then, the second burner 14 is placed inside the burner cover 12. By connecting the second baffle 13 to the through groove near the bottom, the temperature of the hand warmer is increased during use. The heat-conducting structure 22 increases the heat-receiving area of ​​the hand warmer cover 16. At the same time, since the heat-conducting structure 22 supports the inside of the hand warmer cover 16, outside air enters the inside of the air inlet pipe 18 through the air inlet hole 17, and is then directly supplied to the surface of the burner 14 through the concentrating hole 19. Meanwhile, the exchange of hot and cold air inside the hand warmer is completed through the auxiliary hole 20 and the air outlet hole 21. When the connecting block 601 and the fixing block 4 are in contact, the hand warmer cover 16 is better engaged with the hand warmer body 1.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
