Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a multi-angle heating device. Background Technology

[0002] Existing heating devices are widely used in homes, offices, and other heating scenarios. They typically generate heat through electric heating elements to provide users with a warm environment. These devices mostly employ simple heating structures, combined with components such as a base and panel, transferring heat through radiation or convection to meet basic heating needs. In recent years, as users' demands for the versatility and portability of heating equipment have continued to increase, the design of heating devices has gradually evolved towards multifunctionality and flexibility.

[0003] However, existing heating devices still face some limitations in practical use. Traditional heating devices are usually designed with a fixed angle, making it difficult to flexibly adapt to different usage scenarios. In addition, some heating devices achieve angle adjustment through simple support structures, but the adjustment range is limited, making it difficult to meet users' needs for more usage angles. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a multi-angle heating device that solves the problems of fixed angles and limited applications in existing heating devices.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A multi-angle heating device includes a heating film, a bottom shell, a panel, a bracket, a control unit, and a power cord. The bottom shell and the panel are connected to form an inner cavity. The heating film is disposed in the inner cavity and is used to generate heat. The panel is corrugated and has a plurality of through holes evenly distributed on it for transferring heat to the outside. The bracket is rotatably disposed on the bottom shell, and the angle α between the bracket and the bottom shell is adjustable. The control unit is used to control the heating power of the heating film, and the power cord is used to connect to an external power source.

[0007] Preferably, the bracket also includes a support rod, and the bracket is provided with multiple positioning slots. One end of the support rod is pivotally connected to the bottom shell, and the other end of the support rod is detachably abutted against one of the positioning slots.

[0008] Preferably, it also includes a support rod, and the bottom shell is provided with a plurality of positioning grooves. One end of the support rod is pivotally connected to the bracket, and the other end of the support rod is detachably abutted against one of the positioning grooves.

[0009] Preferably, the panel extends to the side near the heating film and is provided with a supporting frame and a plurality of supporting ribs, the supporting frame matching the outer periphery of the heating film, and the bottom shell extends to the side near the heating film and is provided with a plurality of supporting columns, the supporting ribs and the supporting columns being used to support the heating film.

[0010] Preferably, the bracket includes a first support portion, a second support portion, and a third support portion. The first support portion and the second support portion are arranged parallel to each other. The two ends of the third support portion are respectively connected to one end of the first support portion and the second support portion on the same side. The other ends of the first support portion and the second support portion are pivotally connected to the bottom shell.

[0011] Preferably, the third support portion is arranged along the length direction of the heating device, the first support portion and the second support portion are arranged perpendicular to the third support portion, and a plurality of positioning grooves are arranged in pairs at intervals along the length direction of the first support portion or the second support portion on the first support portion and the second support portion.

[0012] Preferably, the lengths of the first support portion and the second support portion are greater than 90% of the width of the heating device, and when the support rod abuts against the positioning groove, the angle α between the bracket and the bottom shell is 10° to 50°.

[0013] Preferably, five pairs of positioning grooves are provided along the length of the first support or the second support. When the bracket abuts against different positioning grooves in sequence, the angle α between the bracket and the bottom shell is 15°, 20°, 25°, 30° and 45° respectively.

[0014] Preferably, the bottom shell is provided with an inwardly recessed receiving groove for accommodating the bracket and the support rod in a folded state.

[0015] Preferably, it also includes a plurality of anti-slip pads, which are respectively disposed on the bottom shell and the bracket.

[0016] The technical solution provided by this utility model can include the following beneficial effects:

[0017] 1. The wavy panel provides a certain air gap, facilitating the diffusion of heat generated by the heating film through air conduction. When used for warming hands or feet, the wavy panel ensures that heat is evenly distributed to the body, achieving the desired warmth. Additionally, pressing on the panel provides a massage effect, enhancing the user experience. The support angle 'a' can be adjusted by rotating the bracket, and the heating power can be adjusted in conjunction with the control unit to meet the heating needs of different scenarios, such as direct contact with the panel for warming hands and feet, or vertical placement for space heating. This is convenient and flexible, solving the problems of existing heating devices having limited functionality and poor user experience.

[0018] 2. The bottom shell, bracket, and support rod form a stable triangular support structure. By abutting the support rod against different positioning slots, the angle between the bottom shell and the bracket can be easily adjusted to meet various usage scenarios and improve the adaptability of the multi-angle heating device.

[0019] 3. The supporting ribs and supporting columns provide support for the heating film from both sides of the thickness direction of the heating film. The supporting frame is fixed and limited along the circumference of the heating film to prevent deformation and displacement of the heating film and extend the overall service life of the heating device.

[0020] 4. The support frame, composed of a first support section, a second support section, and a third support section, forms a stable frame structure. After pivoting with the bottom shell, it allows for multi-angle adjustment, ensuring overall stability of the heating device when used at various angles. This increases the support area and enhances the overall stability of the heating device. When placed horizontally, the angle of the heating device is suitable for direct placement of hands or feet for warmth. Simultaneously, pressing the wavy panel with hands and feet can achieve the therapeutic effect of acupressure. The support frame provides sufficient support area to prevent instability of the heating device under stress during use.

[0021] 5. The first support part, the second support part, and the third support part form a "U"-shaped support frame, which increases the support stability; the positioning grooves are set in pairs at intervals, which facilitates the precise positioning of the support rod and ensures convenient angle adjustment and stability at multiple angles.

[0022] 6. Angle 'a' ranges from 10° to 50°, covering various usage scenarios and meeting diverse user heating needs. Five pairs of positioning slots correspond to five angles: 15°, 20°, 25°, 30°, and 45°, satisfying different usage requirements. When angle 'a' is less than or equal to 30°, the heating device is suitable for horizontal use, facilitating hand or foot warming and providing more comfortable warmth when close to the body. When angle 'a' is greater than 30°, the heating device is suitable for vertical use, such as on a table, providing a uniform spatial heating effect and enhancing usage flexibility.

[0023] 7. The inwardly recessed receiving groove on the bottom shell can accommodate the bracket and support rod, making the heating device more compact when not in use, facilitating storage and carrying, and improving portability and practicality.

[0024] 8. Anti-slip feet increase the friction between the base and bracket and the supporting surface, improving the stability of the device at different angles and on different surfaces, and preventing slippage. Attached Figure Description

One end of the support rod 7 is pivotally connected to the bottom shell 2, and the other end of the support rod 7 is detachably abutted against one of the positioning grooves 40.

[0044] The bottom shell 2, bracket 4 and support rod 7 form a stable triangular support structure. By abutting the support rod 7 against different positioning slots 40, the angle between the bottom shell 2 and the bracket 4 can be easily adjusted to meet various usage scenarios and improve the adaptability of the multi-angle heating device.

[0048] Preferably, a heat insulation layer and a reflective layer are sequentially disposed between the bottom shell 2 and the heating film 1.

[0049] The reflective layer and the heat insulation layer ensure that the heat generated by the heating film 1 is transferred toward the panel 3, thereby improving thermal efficiency and reducing energy loss.

[0051] like Figure 8As shown, the support ribs 32 and support columns 22 provide support for the heating film 1 from both sides of the thickness direction, and the support frame 31 is fixed and limited along the circumference of the heating film 1. In a specific embodiment, the upper side of the heating film 1 directly abuts against the support ribs 32, and the lower side of the heating film 1 is provided with a reflective layer and a heat insulation layer, which are indirectly supported by the support columns 22 through the reflective layer and the heat insulation layer. The support frame 31 completely surrounds the circumference of the heating film 1. The support frame 31, support ribs 32 and support columns 22 cooperate to limit the movement, ensuring that the heating film 1, reflective layer and heat insulation layer can be stably supported at different angles, avoiding deformation and displacement of the heating film 1, and extending the overall service life of the heating device.

[0052] Preferably, the bracket 4 includes a first support portion 41, a second support portion 42 and a third support portion 43. The first support portion 41 and the second support portion 42 are arranged parallel to each other.

The other ends of the first support portion 41 and the second support portion 42 are pivotally connected to the bottom shell 2.

[0053] like Figure 4 As shown, the bracket 4 adopts a stable frame structure composed of a first support part 41, a second support part 42 and a third support part 43. After being pivotally connected to the bottom shell 2, it can achieve multi-angle adjustment, while ensuring that the heating device can maintain overall stability when used at multiple angles.

[0054] Preferably, the distance between the first support part 41 and the second support part 42 is greater than half the overall length of the heating device. This increases the support area and improves the overall stability of the heating device. When placed horizontally, the angle of the heating device is suitable for directly placing hands or feet for warmth. At the same time, the wavy panel 3 can be pressed firmly by hands and feet to achieve the therapeutic effect of acupressure.

When the bracket 4 abuts against different positioning grooves 40 in sequence, the angle α between the bracket 4 and the bottom shell 2 is 15°, 20°, 25°, 30° and 45° respectively.

[0060] Five pairs of positioning slots (40) correspond to five angles: 15°, 20°, 25°, 30°, and 45°, to meet different usage requirements; when angle α is less than or equal to 30°, such as... Figure 5 As shown, the heating device is suitable for use while lying down, making it easy to warm hands or feet, and providing more comfortable warmth when close to the body; when the angle α is greater than 30°, such as Figure 6 As shown, the heating device is suitable for vertical use, such as on a table, to provide a uniform spatial heating effect and improve the flexibility of use. It is best used vertically when the angle a is 45°, as it is not easy to tip over and has a large horizontal heating area.

[0061] Preferably, the positioning groove 40 is a bayonet structure to prevent the support rod (7) from accidentally coming out.

[0062] Preferably, the bottom shell 2 is provided with an inwardly recessed receiving groove 21, which is used to receive the bracket 4 and the support rod 7 in a folded state.
