Description

Technical Field

[0001] This utility model relates to the field of hand warmers, and in particular to a penguin-shaped hand warmer. Background Technology

[0002] Hand warmers are automatic heating and health care products developed using physical and chemical principles. These products are popular due to their novel and unique advantages, such as automatic heating, fun features, and practicality. Hand warmers offer multiple functions including automatic heating and therapeutic health care. Traditional hand warmers are mostly single-module designs with the heating element fixed inside the device, allowing only single-unit use. This results in limited heating area and a fixed form that cannot flexibly adapt to different scenarios. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art by designing a penguin-shaped hand warmer.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a penguin-shaped hand warmer, comprising a front shell, a heating element, a circuit board, a cover plate, a battery, a rear shell, a control switch, and a magnetic adsorption plate. The heating element is embedded in the front shell and electrically connected to the circuit board. The cover plate is located outside the heating element and mounted on the front shell. The battery is fixedly mounted inside the front shell and electrically connected to the circuit board. The circuit board is fixedly mounted inside the rear shell. The front shell and rear shell are connected by bolts. The control switch is fixedly mounted on the rear shell and electrically connected to the circuit board. The magnetic adsorption plate is fixedly mounted inside the rear shell.

[0005] Preferably, the front end housing is provided with an indicator light, which is fixedly installed on the front end housing and electrically connected to the control motherboard.

[0006] Preferably, the front housing is provided with a buckle, which is fixedly installed on the inside of the front housing and engages with the cover plate.

[0007] Preferably, the bolt connection holes between the front end housing and the rear end housing are located within the area covered by the cover plate.

[0008] Preferably, the rear end housing is provided with a positioning block, the positioning block is installed on the rear end housing, and the rear end housing is provided with a positioning groove, the positioning groove being opened on the rear end housing.

[0010] Preferably, the magnetic adsorption sheet is made of magnet, and there are two magnetic adsorption sheets, which are respectively installed on the two sides of the inner side of the rear shell.

[0011] Beneficial effects:

[0012] This utility model provides a penguin-shaped hand warmer with the following beneficial effects. Through its structural design, when in use, pressing the control switch located on the rear shell powers the entire system via a battery. The circuit board, as the core control unit, is responsible for boosting or stabilizing the battery voltage before outputting it to the heating element, driving it to heat up. Simultaneously, the circuit board integrates a temperature control function (built-in temperature control chip), monitoring the heating element temperature in real time and automatically adjusting the power to prevent overheating. The heating element is embedded in the front shell and covered by a cover plate to prevent it from being exposed to the outside. When the heating element malfunctions and needs repair or replacement, the cover plate can be directly removed from the front shell for repair or replacement. During use, the rear shells of the two inventions can be attached together. At this time, the magnetic adsorption sheets inside the two inventions correspond to each other. The two inventions are combined to form a double heating element structure by using magnetic force to attract each other, which nearly doubles the heating area and significantly improves the heating efficiency. It is especially suitable for colder environments or scenarios that require a larger coverage area (such as warming both hands at the same time). Compared with the prior art, the invention, through the layout of concentrated heating at the front and magnets at the rear, avoids direct heat conduction to the magnet area to ensure magnetic stability. It can also be combined by adsorption to form a double heating element structure, which nearly doubles the heating area and significantly improves the heating efficiency, making it suitable for different scenarios.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a penguin hand warmer, including a front shell 1, a heating element 2, a circuit board 3, a cover plate 4, a battery 5, a rear shell 6, a control switch 7, and a magnetic adsorption plate 8. The heating element 2 is embedded in the front shell 1 and is electrically connected to the circuit board 3. The cover plate 4 is located outside the heating element 2 and is installed on the front shell 1. The battery 5 is fixedly installed inside the front shell 1 and is electrically connected to the circuit board 3. The circuit board 3 is fixedly installed inside the rear shell 6. The front shell 1 and the rear shell 6 are connected by bolts. The control switch 7 is fixedly installed on the rear shell 6 and is electrically connected to the circuit board 3. The magnetic adsorption plate 8 is fixedly installed inside the rear shell 6.

[0023] In this utility model, an indicator light 9 is provided on the front housing 1. The indicator light 9 is fixedly installed on the front housing and is electrically connected to the control motherboard. Through the color, flashing frequency and combination state of the indicator light 9 located on the front housing 1, key information such as the operating status of the equipment, safety information and operation results are conveyed to the user or operator, which helps to realize safety control, fault diagnosis and function interaction.

The cover plate 4 and the front shell 1 are connected by the buckle 10 on the front shell 1, which makes it more convenient to remove and install.

[0025] In this utility model, the bolt connection holes between the front shell 1 and the rear shell 6 are located within the area covered by the cover plate 4. After the bolt holes are covered by the cover plate 4, the user cannot directly contact the bolts, thus avoiding bolt loosening due to external force or misoperation. This ensures a long-term tight connection between the front shell 1 and the rear shell 6. At the same time, after the bolt holes are covered by the cover plate 4, there are no exposed screws on the shell surface, improving the simplicity and consistency of the product's appearance.

[0026] In this invention, a positioning block 11 is provided on the rear shell 6. The positioning block 11 is installed on the rear shell 6. A positioning groove 12 is provided on the rear shell 6. The positioning groove 12 is opened on the rear shell 6. By inserting the positioning block 11 on one rear shell 6 into the positioning groove 12 on the other rear shell 6, the positioning block 11 can serve as a reference point to guide the precise docking of the two rear shells 6, ensuring the alignment of the magnetic adsorption sheet 8 and avoiding adsorption failure due to misalignment.

[0027] In this utility model, a charging interface 13 is provided below the circuit board 3. The charging interface 13 is fixedly installed on the circuit board 3 and electrically connected to the circuit board 3. The charging interface 13 is embedded below the rear housing 6. The battery 5 can be directly charged through the charging interface 13 below the circuit board 3. The charging interface 13 is a Type-C interface, which supports bidirectional insertion, avoiding the trouble of repeatedly trying different directions and improving the user experience.

[0028] In this invention, the magnetic adsorption sheet 8 is made of magnet. There are two magnetic adsorption sheets 8, which are respectively installed on the two sides of the inner side of the rear shell 6. The two magnetic adsorption sheets 8 are symmetrically distributed on both sides of the rear shell 6, which can provide uniform adsorption force, ensure the balance and alignment of the two hand warmers when they are combined, and avoid tilting or loosening caused by uneven adsorption force at a single point.

[0029] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0030] In this implementation scheme: During use, pressing the control switch 7 located on the rear housing 6 powers the entire system via the battery 5. The circuit board 3, as the core control unit, is responsible for boosting or stabilizing the voltage of the battery 5 and outputting it to the heating element 2, driving the heating element 2 to generate heat. Simultaneously, the circuit board 3 integrates a temperature control function (built-in temperature control chip), monitoring the temperature of the heating element 2 in real time and automatically adjusting the power to prevent overheating. The indicator light 9 on the front housing 1, through its color, flashing frequency, and combination status, conveys key information such as the equipment's operating status, safety information, and operation results to the user or operator, aiding in safety control, fault diagnosis, and functional interaction. The heating element 2 is embedded in the front housing 1 and covered by a cover plate 4 to prevent it from being exposed to the outside. When the heating element 2 malfunctions and requires repair or replacement, the cover plate 4 can be directly removed from the front housing 1 for repair or replacement. The cover plate 4 is connected to the front housing 1 via a clip 10. It is more convenient to disassemble and install. During use, the two rear shells 6 of this utility model can be attached to each other. By inserting the positioning block 11 on one rear shell 6 into the positioning groove 12 on the other rear shell 6, the positioning block 11 can serve as a reference point to guide the precise docking of the two rear shells 6, ensuring the alignment of the magnetic adsorption sheet 8 and avoiding adsorption failure due to misalignment. A spring is installed between the positioning block 11 and the rear shell 6 as a buffer. At this time, the positions of the magnetic adsorption sheets 8 inside the two utility models correspond to each other. The two utility models are combined to form a double heating element structure by using magnetic force to attract each other. The heating area is nearly doubled, which significantly improves the heating efficiency. It is especially suitable for colder environments or scenarios that require a larger coverage area (such as warming both hands at the same time). The battery 5 can be charged directly through the charging interface 13 below the circuit board 3. The charging interface 13 is a Type-C interface that supports bidirectional insertion, avoiding the trouble of repeatedly trying different directions and improving the user experience.
