The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0046] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.
[0047] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number.

[0049] In scenarios requiring temperature control, such as electronic devices, electrical equipment, and household appliances, traditional heating and temperature control components are typically used to achieve temperature regulation. The structural design of these heating plates has significant limitations: First, the heating components are relatively large, making it difficult to miniaturize the overall size of the heating plate, thus occupying considerable space and hindering its application in compact devices or scenarios with strict installation space requirements. Second, the temperature control components usually rely on mechanical thermostats or complex electronic control systems, which not only increases structural complexity but also raises manufacturing costs and maintenance difficulties. Furthermore, traditional temperature control methods have slow response times and limited temperature regulation accuracy, potentially affecting the stability and energy efficiency of the equipment.
[0050] Therefore, there is an urgent need for a new solution to address the difficulty of installing temperature control devices in compact spaces, and to effectively maintain the equipment at a stable operating temperature. At the same time, the solution should also be easy to use, safe and reliable.
[0051] Reference Figures 1 to 3The self-regulating heating assembly according to the first aspect of this utility model includes a housing 100, a self-regulating heating element 110, and an electrical circuit 109. The housing 100 includes a fixing member 101 and a sliding member 102. The sliding member 102 is slidably connected to the fixing member 101 and can slide along the length direction of the fixing member 101, realizing the installation and removal of the sliding member 102 on the fixing member 101. It is understood that a receiving cavity 103 is defined between the inner sidewall of the fixing member 101 and the inner sidewall of the sliding member 102, and the self-regulating heating element 110 is detachably installed in the receiving cavity 103. Specifically, the self-regulating heating element 110 can be fixed in the inner wall of the receiving cavity 103 by screws or adhesive, which is beneficial for flexible arrangement in a compact space.
[0052] Reference Figure 3 The fixing member 101 and the sliding member 102 can be made of metal profiles formed by bending or stretching metal sheets. The fixing member 101 has first flanges 104 on both sides, which are inclined in the width direction of the fixing member 101 and extend from the outside of the fixing member 101 in a direction away from the outer peripheral wall of the fixing member 101. Thus, the inner sidewall of the first flange 104 and the fixing member 101 define a guide groove 107 with a V-shaped cross-section. Meanwhile, the sliding member 102 has a second flange 105, which is inclined in the width direction of the sliding member 102 and extends outward from the outer peripheral wall of the sliding member 102. The second flange 105 can be inserted into the guide groove 107, thereby realizing the sliding connection of the sliding member 102 to the fixing member 101. Furthermore, a third flange 106 is provided at the end of the second flange 105 away from the sliding member 102. The third flange 106 extends from the end of the second flange 105 towards the center of the sliding member 102 along the width direction of the fixing member 101, and the third flange 106 is parallel to the width direction of the sliding member 102. Thus, the second flange 105 and the third flange 106 together constitute a guide strip 108 with a V-shaped cross-section. It can be understood that when the guide strip 108 is inserted into the guide groove 107, the outer wall of the third flange 106 abuts against the inner wall of the fixing member 101, and the outer wall of the second flange 105 abuts against the inner side of the first flange 104, thereby allowing the sliding member 102 to slide only along the length direction of the fixing member 101, preventing it from coming out, and ensuring installation stability and ease of assembly and disassembly.
[0053] Reference Figures 4 to 6The frame body of the second aspect embodiment of this utility model includes the aforementioned self-regulating heating assembly. It also includes a body 120, which has a rectangular member 121. The rectangular member 121 includes multiple components 122. Both ends of a fixing member 101 are fixedly connected to the ends of the components 122. The self-regulating heating element 110 can heat the body 120. Specifically, the rectangular member 121 has at least one fixing member 101 and three components 122, and the length direction of the components 122 is perpendicular to the length direction of the fixing member 101, thus forming a quadrilateral structure of the body 120. It is understood that the fixing member 101 is provided with a slidable sliding member 102, and the fixing member 101 has a receiving cavity 103, in which the self-regulating heating element 110 is placed. Furthermore, the self-regulating heating element 110 is wound around the receiving cavity 103, thereby increasing the surface area of the self-regulating heating element 110 and improving the contact area between the self-regulating heating element 110 and the inner peripheral wall of the receiving cavity 103. This helps to increase the heating power and the surface area for heat transfer, which is beneficial for the target equipment to quickly reach a stable temperature, while also reducing humidity. It is understood that the rectangular component 121 can be a door frame, window frame, or a frame with a box-like structure, capable of heating and insulating the interior, windows, or objects stored in the box-like structure. Furthermore, fixing members 101 for mounting the self-regulating heating element 110 can be provided on all four sides of the rectangular component 121, which can increase heating efficiency and improve heating uniformity.
[0054] It is understood that the slider 102 has outwardly extending guide strips 108 on both sides of the fixing member 101 along the width direction, and the fixing member 101 has guide grooves 107 on both sides of its width direction. The guide strips 108 can be inserted into the guide grooves 107 to realize the sliding connection of the slider 102 on the fixing member 101.
[0055] Reference Figure 7 In some embodiments, the body 120 has multiple rectangular members 121, which can form a hexahedral frame. It is understood that this hexahedral frame can be applied to components with box-like structures, such as wardrobes and filing cabinets. Further, at least one rectangular member 121 has a self-regulating heating element, which has a housing 100. The housing 100 includes a fixing member 101 and a sliding member 102. The two ends of the fixing member 101 are connected to the rectangular member 121, and a wound self-regulating heating element 110 can be installed within the fixing member 101, effectively reducing space occupation and improving the structural compactness of the body 120, thereby enhancing its flexibility in different application scenarios. In some embodiments, self-regulating heating elements are provided within multiple rectangular members 121, which increases heating efficiency, and arranging more self-regulating heating elements 110 improves heating uniformity.
[0056] Reference Figure 8 It is understood that the sliding member 102 has an L-shaped cross-section and a covering portion 123 extending along the width and height directions, respectively, which can cover the fixing member 101. Simultaneously, the covering portion 123 has an outwardly extending guide strip 108, and the fixing member 101 is provided with a guide groove 107 for inserting the guide strip 108, thereby realizing the sliding installation and removal of the sliding member 102 on the fixing member 101. Furthermore, the fixing member 101 and the sliding member 102 can form a receiving cavity 103, in which a self-regulating heating element 110 can be installed. The self-regulating heating element 110 is wound and arranged within the receiving cavity 103, thereby increasing the surface area of the self-regulating heating element 110 and improving the contact area between the self-regulating heating element 110 and the inner peripheral wall of the receiving cavity 103. This helps to increase the heating power and the surface area for outward heat transfer, which is beneficial for the target equipment to quickly reach a stable temperature and reduce humidity.
[0057] Reference Figure 9 In a third aspect of this utility model, a storage box is provided, including the aforementioned frame. It also includes a box body 130, which has multiple rectangular members 121 that form a hexahedral skeleton within the box body 130. The outer peripheral wall of the box body 130 is provided with an outer shell 131 that covers the outer periphery of the skeleton. Simultaneously, the outer peripheral wall of the box body 130 is provided with a self-regulating heating element, which includes a housing 100 and a self-regulating heating element 110 installed within the housing 100. The self-regulating heating element 110 can heat the box body 130. It is understood that the housing 100 includes a fixing member 101 and a sliding member 102. The sliding member 102 has outwardly extending guide strips 108 on both sides along the width direction, and the fixing member 101 has receiving grooves on both sides along the width direction. When the sliding member 102 is installed in the fixing member 101, the guide strips 108 can be inserted into the receiving grooves to realize the installation and removal of the sliding member 102, thereby improving the ease of installation and removal of the self-regulating heating element 110. It is understood that the self-regulating heating element can be installed on any peripheral wall of the housing 130, which can reduce the occupation of the internal space of the housing 130, thereby enabling the arrangement of the self-regulating heating element 110 in a compact space layout, which is beneficial to improving the flexibility of use.
[0058] In this embodiment, the length direction of the fixing member 101 is parallel to the height direction of the housing 130, and the width direction of the fixing member 101 is parallel to the width direction of the housing 130. The sliding member 102 is inserted and installed on the fixing member 101 along the height direction. Therefore, a hinged flip cover 132 is provided on the top of the housing 130, which provides an opening for pulling out the sliding member 102 when the flip cover 132 is opened, thereby improving the ease of disassembly and assembly of the self-regulating heating element 110. In some embodiments, the length direction of the fixing member 101 is parallel to the horizontal direction. In some embodiments, self-regulating heating components are installed on multiple peripheral walls of the housing 130, which can increase the effective heating area and thus improve heating efficiency and heating uniformity.
[0059] Reference Figure 2 It is understandable that the energizing circuit 109 is arranged on the self-regulating heating element 110. The energizing circuit 109 is used to connect to the power supply and supply power to the self-regulating heating element 110, driving the self-regulating heating element 110 to heat up to the preset temperature and maintain it at the preset temperature. (Refer to...) Figure 10 It is understood that the self-regulating heating element 110 comprises a first PI film layer 111, a conductive layer 112, an electroplated layer 113, a PTC paste layer 114, and a second PI film layer 115, sequentially laminated together. This structure not only provides excellent mechanical strength and electrical insulation properties, but the electroplated layer 113 also prevents the conductive layer 112 from being oxidized. Furthermore, the use of the PTC paste layer 114 ensures that the heating element has good self-regulating temperature characteristics, automatically adjusting the heat output according to changes in ambient temperature to avoid overheating and ensure the safety and stability of the heating element's operation. The preset temperature is F, satisfying: 40℃≤F≤50℃. This temperature range effectively raises the operating temperature around the target equipment without damaging it. By precisely controlling the temperature of the heating element, it can be ensured that the target equipment always operates in a favorable temperature environment, avoiding both low-temperature inefficiency and high-temperature-induced equipment failure. Specifically, the preset temperature is 45℃. For reference, see the patent application publication number CN109907878A, entitled "A Rapid Heating Constant Temperature Hot Compress and Its Preparation Method", and the patent application publication number CN108503940A, entitled "A Low Curie Temperature Point PTC Organic Composite Material and Its Preparation Method".
