[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a heating device 10 is provided, including a heating body 100, a cover 200, a first side plate 300, a second side plate 400, and a suspension structure 500. The cover 200 is rotatably mounted on the heating body 100 and has an open position and a closed position. The first side plate 300 and the second side plate 400 are both movably mounted between the heating body 100 and the cover 200. The first side plate 300 and the second side plate 400 are configured to form a heating space with the heating body 100 and the cover 200 when the cover 200 is rotated to the open position, and to be housed between the heating body 100 and the cover 200 when the cover 200 is rotated to the closed position. The suspension structure 500 is mounted on the heating body 100 and is used to apply resistance to the cover 200 so that the cover 200 can be suspended.

[0034] In the heating device 10 described above, when heating is required, the cover 200 is rotated toward the open position, and the first side plate 300 and the second side plate 400 are both moved toward the outside of the heating device 10. When the cover 200 is rotated to the open position, the suspension structure 500 applies resistance to the cover 200 so that the cover 200 can be suspended in the open position. The heating body 100, the cover 200, the first side plate 300 and the second side plate 400 are arranged to form a heating space, reducing the rate of heat loss and achieving the effect of heat preservation and energy saving. When storage is required, both the first side panel 300 and the second side panel 400 are moved toward the interior of the heating device 10, and the cover 200 is rotated toward the closed position. When the cover 200 is rotated to the closed position, both the first side panel 300 and the second side panel 400 are stored between the heating body 100 and the cover 200, which significantly reduces the height of the heating device 10, making it easier to store, organize and place, and improving the practicality and user experience of the heating device 10.

[0035] The heating body 100 can be configured as any of the existing structures for heating and warmth.

[0036] like Figure 4As shown, optionally, the heating body 100 includes a base 113, a mica plate 114, an electric heating film 115, a rubber pad 116, a pressure plate 117, a display panel 118, a control board 119, and a bottom cover 120. The top surface of the base 113 has a first recess 121, and the bottom surface of the base 113 also has a second recess. The mica plate 114 is disposed within the first recess 121. The electric heating film 115 is disposed on top of the mica plate 114. The rubber pad 116 is disposed on top of the electric heating film 115. The pressure plate 117 is disposed on top of the rubber pad 116. The pressure plate 117 is fixed to the base 113 by screws. The control board 119 is disposed within and fixed to the second recess. The bottom cover 120 is fixed to the bottom of the base 113 to cover the second recess. The head of the base 113 also has a second recessed platform 123, and the display panel 118 is mounted on the second recessed platform 123.

[0037] Specifically, the bottom wall of the first cavity 121 is also provided with at least one mounting groove 124. The heating body 100 also includes rollers 125, the number of which is the same as the number of mounting grooves 124, and each roller 125 is installed in its respective mounting groove 124. The mica plate 114, the electric heating film 115, and the rubber pad 116 are all provided with clearance holes to avoid the top of the rollers 125. The pressure plate 117 is provided with a central hole, the inner contour shape of which is adapted to the outer contour shape of the mica plate 114, the outer contour shape of the electric heating film 115, and the outer contour shape of the rubber pad 116. The pressure plate 117 is used to press the four edges of the rubber pad 116, the four edges of the electric heating film 115, and the four edges of the mica plate 114 onto the base 113 in sequence.

[0038] It should be noted that during the opening and closing of the cover 200, the order of the rotation steps of the cover 200 and the movement steps of the first side plate 300 and the second side plate 400 can be flexibly adjusted according to actual usage needs. That is, the rotation steps of the cover 200 and the movement steps of the first side plate 300 and the second side plate 400 can be performed simultaneously or sequentially.

[0039] Both the first side panel 300 and the second side panel 400 can be foldable or non-foldable. Specifically, in this embodiment, both the first side panel 300 and the second side panel 400 are integrally made of flexible material and symmetrically arranged on opposite sides of the heating body 100 (the following will describe the left and right sides as examples). When the cover 200 is in the open position, both the first side panel 300 and the second side panel 400 are completely flattened.

[0040] like Figure 3 and Figure 4As shown, in one embodiment, both the first side plate 300 and the second side plate 400 are foldable structures. The first side plate 300 and the second side plate 400 are located on opposite sides of the heating body 100 and are connected to both the heating body 100 and the cover 200. Both the first side plate 300 and the second side plate 400 have folded and extended states. When the cover 200 is moved to the open position, both the first side plate 300 and the second side plate 400 are in the extended state, forming a heating space with the heating body 100 and the cover 200. When the cover 200 is rotated to the closed position, both the first side plate 300 and the second side plate 400 are in the folded state and are stored between the heating body 100 and the cover 200.

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, further, the heating body 100 near the cover 200, or the cover 200 near the heating body 100, is provided with a first storage cavity 211 and a second storage cavity 212. The first storage cavity 211 is correspondingly disposed with the first side plate 300 and is configured to store the first side plate 300 when the cover 200 is moved to the closed position. The second storage cavity 212 is correspondingly disposed with the second side plate 400 and is configured to store the second side plate 400 when the cover 200 is moved to the closed position. In this way, when the cover 200 is moved to the closed position, the first side plate 300 and the second side plate 400 can be correspondingly hidden inside the cover 200 or the heating body 100, without occupying additional height space, so that the height of the heating device 10 can be further reduced, improving the practicality of the heating device 10.

[0042] Specifically, in this embodiment, when the heating device 10 is in the heating state, the size of the heating device 10 is 370mm*320mm*210mm; when the heating device 10 is in the storage state, the size of the heating device 10 is 370mm*320mm*35mm.

[0043] Specifically, in this embodiment, the cover 200 includes an upper cover 217 and an inner cover 216. The inner cover 216 is located between the upper cover 217 and the heating body 100, and can be fixedly connected to the upper cover 217 by snap-fit, screw-fit, or other means. The first storage cavity 211 and the second storage cavity 212 are symmetrically arranged on the left and right sides of the inner cover 216 away from the cover 200. The inner cover 216 is also provided with a clearance groove for avoiding the roller 125.

[0044] like Figure 3 and Figure 5 As shown, optionally, the inner contour shape of the first storage cavity 211 matches the outer contour shape of the first side plate 300 in the folded state. The inner contour shape of the second storage cavity 212 matches the outer contour shape of the second side plate 400 in the folded state.

[0045] Specifically, in this embodiment, the left and right sides of the inner cover 216 away from the upper cover 217 are recessed to form a first storage cavity 211 and a second storage cavity 212. Both the first storage cavity 211 and the second storage cavity 212 are fan-shaped, ensuring that the first side panel 300 can be stored in the first storage cavity 211 after folding, and that the second side panel 400 can be stored in the second storage cavity 212 after folding, thereby improving the reliability of the heating device 10.

[0046] Both the first side plate 300 and the second side plate 400 can be connected to the left and right sides of the cover 200 by snap-fit, plug-in, screw-in or other means. Both the first side plate 300 and the second side plate 400 can be connected to the left and right sides of the heating body 100 by snap-fit, plug-in, screw-in or other means.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the cover 200 has a first connecting portion 213 on both its left and right sides. The heating body 100 has a second connecting portion 111 on both its left and right sides. The upper part of the first side plate 300 and the upper part of the second side plate 400 are each provided with a third connecting portion 311 that connects to the first connecting portion 213. The lower part of the first side plate 300 and the lower part of the second side plate 400 are each provided with a fourth connecting portion 312 that connects to the second connecting portion 111. Thus, the first side plate 300 and the second side plate 400 can be installed on the cover 200 through the first connecting portion 213 and the third connecting portion 311, and the first side plate 300 and the second side plate 400 can be installed on the heating body 100 through the second connecting portion 111 and the fourth connecting portion 312, improving the ease of assembly of the heating device 10.

[0048] The number and position of the first connecting part 213, the second connecting part 111, the third connecting part 311, and the fourth connecting part 312 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the first connecting part 213 and the third connecting part 311 are detachably connected, and the second connecting part 111 and the fourth connecting part 312 are detachably connected. In this way, both the first side plate 300 and the second side plate 400 can be removed from the heating device 10 for easy maintenance or replacement, thereby improving the service life of the heating device 10.

[0049] like Figure 5 and Figure 6 As shown, optionally, the first connecting part 213 is configured as a snap hole, and the second connecting part 111 is configured as a snap groove. The number of snap holes and snap grooves are both at least one. Each snap hole on the left and right sides of the cover 200 is along the width direction of the cover 200 (e.g., ...). Figure 2The three connecting parts 311 are arranged at intervals (as shown in direction A). The number of first fasteners is the same as the number of fastening holes, and each first fastener is fastened to each corresponding fastening hole. The fastening slots on the left and right sides of the heating body 100 are all along the width direction of the heating body 100 (e.g., as shown in direction A). Figure 2 (In the direction shown in A) the fourth connecting part 312 is set as a second buckle, the number of second buckles is the same as the number of buckle slots, and each second buckle is fastened to each buckle slot.

[0050] Specifically, in this embodiment, there are eight snap holes, which are respectively located on the inner sidewalls of the first receiving cavity 211 and the second receiving cavity 212 on opposite sides. There are four snap slots, which are respectively located on the left and right sides of the top surface of the heating body 100. The upper part of the first side plate 300 and the upper part of the second side plate 400 are each provided with four first retaining strips. The lower part of the first side plate 300 and the lower part of the second side plate 400 are each provided with two second retaining strips.

[0051] like Figure 6 As shown, in one embodiment, both the first side plate 300 and the second side plate 400 are configured as flexible plates. The upper part of the flexible plate has a first side groove 313, and the lower part has a second side groove 314. Both the first side groove 313 and the second side groove 314 are configured to bend inwards when the flexible plate is in a folded state. Thus, the strength at the first side groove 313 and the second side groove 314 is relatively low, ensuring that when the cover 200 switches from the open position to the closed position, the upper part of the flexible plate folds inwards at the first side groove 313, and the lower part folds inwards at the second side groove 314. This ensures that the two flexible plates can be folded and stored in the first storage cavity 211 and the second storage cavity 212 respectively, improving the reliability of the heating device 10.

[0052] It should be noted that both the first side groove 313 and the second side groove 314 are thin-walled structures. The two first side grooves 313 and the two second side grooves 314 are located on the sides of the two flexible plates that are close to each other.

[0053] like Figure 1 and Figure 4 As shown, in one embodiment, the tail of the cover 200 is rotatably connected to the heating body 100, so that the cover 200 can rotate to an open position and a closed position. In this way, the cover 200 can rotate along a fixed path to stably and reliably switch between the open position and the closed position, improving the reliability of the heating device 10.

[0054] In other embodiments, the cover 200 may also be movably connected to the heating body 100 via a flexible structure.

[0055] like Figure 4 and Figure 5As shown, optionally, both the first side plate 300 and the second side plate 400 are made of flexible plates. A folding groove 315 is provided in the middle of the flexible plate. The extension line of the folding groove 315 intersects the rotation axis of the cover 200. The folding groove 315 is configured to bend outwards when the flexible plate is in a folded state. Thus, the strength at the folding groove 315 is relatively low, ensuring that when the cover 200 switches from the open position to the closed position, the flexible plate can be folded and stored in the first storage cavity 211 and the second storage cavity 212, improving the reliability of the heating device 10.

[0056] It should be noted that the folding groove 315 is a thin-walled structure. The two folding grooves 315 are located on the sides of the two flexible plates that are close to each other.

[0057] Specifically, in this embodiment, when the cover 200 is switched from the open position to the closed position, the two first side grooves 313 and the two second side grooves 314 are bent 90° toward the inside of the heating device 10, and the two folding grooves 315 are bent 180° toward the outside of the heating device 10, so that the two flexible plates are in a folded state and are respectively stored in the first storage cavity 211 and the second storage cavity 212.

[0058] In one embodiment, both the first side panel 300 and the second side panel 400 are non-foldable structures. One end of the first side panel 300 and one end of the second side panel 400 are rotatably connected to one of the heating body 100 and the cover 200, while the other ends of the first side panel 300 and the second side panel 400 are detachably connected to the other of the heating body 100 and the cover 200. Thus, when heating is needed, the cover 200 is rotated toward the closed position, and both the first side panel 300 and the second side panel 400 are rotated toward the outside of the heating device 10. When the cover 200 is rotated to the open position, both the first side panel 300 and the second side panel 400 are detachably connected to the corresponding one of the heating body 100 and the cover 200. At this time, both the first side panel 300 and the second side panel 400 are in a vertical state and are arranged with the heating body 100 and the cover 200 to form a heating space, reducing the rate of heat loss and achieving a heat preservation and energy-saving effect. When storage is required, the detachable connection between the first side plate 300 and one of the corresponding heating body 100 and cover 200 is released, and the detachable connection between the second side plate 400 and one of the corresponding heating body 100 and cover 200 is released. The first side plate 300 and the second side plate 400 are moved toward the interior of the heating device 10, and the cover 200 is rotated toward the closed position. When the cover 200 is rotated to the closed position, the first side plate 300 and the second side plate 400 are both in a horizontal state and are stored between the heating body 100 and the cover 200, which significantly reduces the height of the heating device 10, making it easier to store, organize and place, and improving the practicality and user experience of the heating device 10.

[0059] like Figure 4 and Figure 7 As shown, in one embodiment, the heating device 10 further includes a rotating member 600, which is used to rotatably connect the cover 200 to the heating body 100.

[0060] The rotating component 600 can be configured as a hinge, a chain, or other rotating connection structure. The number of rotating components 600 can be flexibly adjusted according to actual usage requirements.

[0061] Specifically, in this embodiment, the rotating component 600 is configured as a hinge, and the number of hinges is at least one. Each hinge is positioned along the length direction of the heating body 100 (e.g., ...). Figure 2 The hinges are spaced apart (as shown in direction B), with both ends of each hinge fixedly connected to the tail of the heating body 100 and the tail of the cover 200, respectively. Specifically, one end of the hinge is fixedly connected to the side of the inner cover 216 near the upper cover 217, and the other end is fixedly connected to the side of the tail of the base 113. There are two hinges, symmetrically arranged on the left and right sides of the tail of the heating device 10.

[0062] The hinge can be fixedly connected to the tail of the heating body 100 and the tail of the cover 200 by screwing, snapping or other means.

[0063] The hovering structure 500 can be configured as any structure in the prior art that allows the cover 200 to hover in the open position.

[0064] like Figure 4 and Figure 7 As shown, in one embodiment, the hovering structure 500 includes a damping element 511, which is mounted on the heating body 100 and frictionally engages with the cover 200. Thus, when the cover 200 rotates to the open position, the damping element 511 rubs against the cover 200 to apply a frictional force, allowing the cover 200 to stop in the open position. This design is simple, easy to operate, and low in cost.

[0065] In this specific embodiment, the damping element 511 is configured as a damping block, which can be fixedly installed on the heating body 100 by snap-fit, plug-in, screw-in, or other means. In other embodiments, the damping element 511 can also be configured as a damping pad, damping sleeve, or other damping structure.

[0066] like Figure 7 As shown, optionally, the rear end of the heating body 100 is provided with a first recessed platform 122, and the damping element 511 is installed on the first recessed platform 122. In this way, the first recessed platform 122 can play a limiting and positioning role, ensuring that the damping element 511 can be quickly and accurately installed on the heating body 100, thereby improving the convenience of the heating device 10.

[0067] Specifically, in this embodiment, the first sinking platform 122 can be formed by stamping the tail of the base 113.

[0068] like Figure 4 and Figure 7 As shown, in one embodiment, the cover 200 is provided with a friction boss 214, which frictionally engages with the damping member 511. Thus, through the frictional engagement between the cover 200 and the damping member 511, the position of the damping member 511 can be flexibly adjusted according to usage needs, improving the practicality of the heating device 10.

[0069] like Figure 4 and Figure 7 As shown, optionally, the cover 200 includes an upper cover 217 and an inner cover 216. The inner cover 216 is located between the upper cover 217 and the heating body 100 and is fixedly connected to the upper cover 217. A friction boss 214 is provided at the tail of the inner cover 216.

[0070] In this specific embodiment, the friction boss 214 and the inner cover 216 are an integral structure. For example, the friction boss 214 can be formed by stamping the tail of the inner cover 216. In other embodiments, the friction boss 214 and the inner cover 216 can also be separate structures. For example, the friction boss 214 can be installed on the tail of the inner cover 216 by snap-fit, screw-fit, or other fixed connection methods.

[0071] The number of damping components 511 and friction bosses 214 can be flexibly adjusted according to actual usage needs.

[0072] like Figure 4 and Figure 7 As shown, optionally, the number of damping elements 511 is at least one, and each damping element 511 is spaced apart along the length direction of the heating body 100 and is in frictional engagement with the friction boss 214. In this way, by increasing the number of damping elements 511, the number of friction surfaces between the damping elements 511 and the friction boss 214 is increased, ensuring that the cover 200 can be stably and reliably suspended in the open position, thereby improving the reliability of the heating device 10.

[0073] Specifically, in this embodiment, the number of friction bosses 214 is one, and they extend along the length of the cover 200 (e.g., Figure 2 (As shown in direction B). There are two damping elements 511, which are spaced apart along the length of the heating body 100 and are in frictional engagement with the friction boss 214. The number of first recessed platforms 122 is the same as the number of damping elements 511, and each damping element 511 is correspondingly arranged with each first recessed platform 122.

[0074] like Figure 4 and Figure 5As shown, optionally, the friction boss 214 has a first arc surface, and the damping member 511 has a second arc surface. The first arc surface and the second arc surface are in surface contact and frictionally engage with each other. Thus, the friction boss 214 and the damping member 511 engage through the frictional engagement of the first and second arc surfaces, increasing the frictional area between a single damping member 511 and the friction boss 214. This ensures that the cover 200 can be stably and reliably suspended in the open position, improving the reliability of the heating device 10.

[0075] In this specific embodiment, the axis of the first arc surface, the axis of the second arc surface, and the rotation axis of the cover 200 coincide. Each damping element 511 is provided with a second arc surface. The number of first arc surfaces is the same as the number of second arc surfaces.

[0076] like Figure 4 and Figure 7 As shown, in one embodiment, the friction boss 214 is provided with a first limiting part 215, and the heating body 100 is provided with a second limiting part 112. The second limiting part 112 is configured to engage with the first limiting part 215 when the cover 200 is rotated to the open position. In this way, the first limiting part 215 and the second limiting part 112 can cooperate to limit the maximum rotation angle of the cover 200, preventing the first side plate 300 and the second side plate 400 from being damaged due to excessive rotation angle, thereby improving the reliability of the heating device 10.

[0077] The first limiting part 215 and the second limiting part 112 can both be configured as limiting blocks, limiting protrusions, or other limiting structures. The number of the first limiting part 215 and the second limiting part 112 can be flexibly adjusted according to actual usage needs.

[0078] Specifically, in this embodiment, there are two of each of the first arc surface, damping element 511, and first recessed platform 122. The second limiting part 112 is an integral structure with the base 113 and is located between the two first recessed platforms 122. The first limiting part 215 is located in the middle of the friction boss 214, and the two first arc surfaces are located on the left and right sides of the first limiting part, ensuring that the force on the friction boss 214 is uniform when the first limiting part 215 collides and limits with the second limiting part 112, thereby improving the reliability of the heating device 10.

[0079] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0080] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0081] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0082] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0083] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0084] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
