[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It should be noted that when an element is referred to as being “fixed to” or “disposed on” another element, it may be directly on the other element or indirectly on the other element.

[0036] When an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0039] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0040] In order to solve the technical problem in the prior art that heat cannot be evenly gathered into each heating area, thus resulting in low heating efficiency; for this purpose, an embodiment of the utility model provides a heating cover.

[0041] The following is a detailed description of the specific structure of a heating cover provided by the present utility model embodiment. Figure 1-4 As shown in the figure, the specific structure of the heating cover includes a body box 1, a heat-conducting frame 2, a heating coil body 3, a warming cover 4 and a control component 5.

[0042] The first installation cavity is formed in the hollow space of the body box 1. Specifically, the installation cavity is used to house the above-mentioned heat-conducting frame 2, heating coil 3, thermal cover 4 and control component 5, so as to provide additional protection for the above-mentioned built-in components and prevent external factors from damaging the components; at the same time, the installation cavity can also provide additional thermal insulation performance, thereby reducing heat transfer and energy loss.

[0043] As mentioned above, when the heating coil 3 of the embodiment of the utility model generates heat, the heating efficiency of the heated body is improved through the installation cavity, thereby preventing the heat from decreasing.

[0044] The heat-conducting frame 2 is detachably built into the first installation cavity. The heat-conducting frame 2 is hollow to form a placement cavity 21 with an opening on one side for placing a heat receiving body. A sealing plate 22 for opening or closing the opening is provided on the body box 1.

[0045] Specifically, since a placement cavity 21 that is connected to the outside is formed on one side of the heat-conducting frame 2, if some heat-receiving bodies need to be heated, the heat-receiving bodies can be directly placed into the placement cavity 21 through the opening of the heat-conducting frame 2, and then the heating coil 3 is controlled to work until the heat-receiving body is heated to the target temperature. In this process, since the opening is closed, heat is prevented from dissipating outside the placement cavity 21, so that the heat-receiving body can be quickly heated up or maintained at the target temperature.

[0046] After the heated body is placed in the placement cavity 21, the opening is sealed by the sealing plate 22 to make the placement cavity 21 in a sealed state. Subsequently, when the heated body is heated, the heated body is quickly heated up and the heat is dissipated from the opening, thereby achieving a faster and more uniform heating process.

[0047] It should be noted that, since the heat-conducting frame 2 of the embodiment of the utility model is detachably arranged in the installation cavity, it is convenient to disassemble the entire heat-conducting frame 2 in the subsequent process if some parts are damaged. For example, a locking hole is provided on the heat-conducting frame 2, and a fixing hole is provided on the cavity wall of the installation cavity, and a locking member is simultaneously inserted into the locking hole and the fixing hole to fix the heat-conducting frame 2 in the installation cavity; when disassembling, the heat-conducting frame 2 can be taken out by only removing the locking member from the locking hole and the fixing hole.

[0048] It should also be noted that the aforementioned locking holes and fixing holes are both threaded holes, and correspondingly, the locking members are bolts.

[0049] According to the attached Figure 3 As shown, the inner side surface of the heating coil 3 is sleeved on the outer side wall of the heat-conducting frame 2. Specifically, the inner side surfaces of the heating coil 3 are respectively in contact with the top surface, bottom surface and side surface of the heat-conducting frame 2 for conducting heat. When the heating coil 3 generates heat, the heating area of ​​the heat-conducting frame 2 can be increased. Subsequently, the heated heat-conducting frame 2 can conduct the heat to the placement cavity 21 through the heat-conducting frame 2, thereby quickly heating the heat-receiving body in the placement cavity 21, so that the heat can be evenly distributed or heat exchanged.

[0050] It can be understood that the thermally conductive frame 2 of the embodiment of the utility model is a metal thermally conductive frame (made of aluminum alloy, copper, steel and other materials) or a composite thermally conductive frame (made of a combination of metal and other materials such as ceramics and plastics). Correspondingly, the heating coil 3 of the embodiment of the utility model is a resistance wire heating coil or an inductive heating coil, and the specific type is not limited here.

[0051] According to the attached Figure 3 As shown, the thermal cover 4 is sleeved on the outer side of the heating coil 3. Specifically, when the heating coil is heated, the thermal cover 4 reduces the loss of heat conducted to the external environment, improves the heating effect on the heated body, reduces energy waste and improves heating efficiency; at the same time, it can be used to stabilize the temperature of the placement cavity 21, prevent excessive fluctuations in the temperature of the placement cavity 21 or local overheating, resulting in uneven heating, and further improve the stability and reliability of the heating process; at the same time, since the heating coil generates high temperature when heated, the thermal cover 4 reduces the heating temperature of the heating coil and other components (non-heat-conducting frame 2) to prevent other components from being damaged due to excessive high temperature.

[0052] It can be understood that the thermal cover 4 of the embodiment of the utility model is a cotton cover or a rubber cover; specifically, both types of thermal covers 4 have good thermal insulation performance and durability, and can withstand higher temperature heating requirements, so they are suitable for use in high temperature environments, and the specific type is not limited here.

[0053] According to the attached Figure 1 and attached Figure 4 As shown, the control component 5 is arranged in the body box 1, and the control component 5 includes a power supply and a control module. The power supply is electrically connected to the heating coil 3, and the control module is control-connected to the power supply.

[0054] Specifically, the working state of the heating coil 3 is controlled by the control module to ensure that the heat receiving body is heated to a temperature that is always maintained within the set target temperature range. For example, the control module includes a temperature sensor for continuously monitoring the temperature change of the heat receiving body, and then continuously adjusts the heating coil 3 to perform heating through power supply to keep the temperature of the heat receiving body within the set target temperature range.

[0055] To sum up the above, the control module controls the power supply to supply power to the heating coil 3, and the heating coil 3 quickly heats up the heat-conducting frame 2 when generating heat, thereby heating the heat-receiving body located in the placement cavity 21. Since the heating coil 3 is sleeved on the outer wall of the heat-conducting frame 2, and the thermal cover 4 is sleeved on the outer side of the heating coil 3, the heat generated by the heating coil 3 can be quickly dispersed to the entire heat-conducting frame 2, thereby avoiding the condition that the heat-receiving body inside the heat-conducting frame 2 is heated unevenly due to the local temperature being too high.

[0056] In some specific embodiments, an aluminum plate 11 is disposed in the first installation cavity, and the aluminum plate 11 surrounds the heat-conducting frame 2 .

[0057] Specifically, since the aluminum plate 11 is resistant to high temperatures, it surrounds the heat-conducting frame 2 , thereby protecting the cavity wall of the first installation cavity and preventing the high heat generated by the heating coil from being transferred to the body box 1 .

[0058] According to the attached Figure 3 As shown, in a further embodiment, the heating cover further comprises a supporting base frame 12 for supporting the heat-conducting frame 2, and a supporting end of the supporting base frame 12 is arranged on the bottom surface of the aluminum plate.

[0059] Specifically, the heat-conducting frame 2 is arranged on the top of the supporting base 12, and the supporting effect of the supporting base 12 is used to provide stable support for the heat-conducting frame 2, thereby preventing the heat-conducting frame 2 from tilting, shaking or sinking, and ensuring the normal operation of the entire heating hood; at the same time, since only the supporting end of the supporting base 12 is in contact with the side of the aluminum plate 11, the heat-conducting frame 2 or the heating coil 3 is prevented from contacting the aluminum plate 11 or other components of this embodiment over a large area when in the heating state, thereby preventing the heat-conducting frame 2 or the heating coil 3 from being damaged by the aluminum plate 11 or other components under high temperature.

[0060] According to the attached Figure 3 As shown, in a further embodiment, a plurality of through holes 111 are formed on the side of the aluminum plate 11, and the number of through holes 111 is not limited here. Specifically, the plurality of through holes 111 are used to promote air circulation and prevent heat accumulation on the body box 1 or inside the first installation cavity, so that a suitable temperature environment can be maintained except for the heating area.

[0061] According to the attached Figure 3As shown, in some specific embodiments, a portion of the heat-conducting frame 2 is provided with a mica fixing plate 23. Specifically, since the mica fixing plate 23 has excellent insulation performance, it can effectively isolate the heat transfer and power transmission between the heating coil 3 and other components, that is, prevent other components from affecting or damaging the heating element; at the same time, the mica fixing plate 23 has a relatively low thermal conductivity, and can disperse the heat generated by the heating coil 3 to the entire heat-conducting frame 2, thereby avoiding the situation where the internal heating element of the heat-conducting frame 2 is heated unevenly due to excessive local temperature.

[0062] According to the attached Figure 1 As shown, in some specific embodiments, a hinge 16 is provided on the body box 1 , and the sealing plate 22 is rotatably connected to the hinge 16 .

[0063] Specifically, the sealing plate 22 is rotatably arranged at the opening of the body box 1 through the hinge 16. When the sealing plate 22 opens or closes the opening, it can open and close smoothly. This arrangement can support and connect the sealing plate 22, improve the smoothness and stability of the sealing plate 22, and also support the sealing plate 22 during the opening and closing process.

[0064] According to the attached Figure 2 As shown, in some specific embodiments, the body box 1 is also hollowed to form a second installation cavity 13 for the built-in control component 5; a partition 14 is provided between the second installation cavity 13 and the first installation cavity to separate the second installation cavity 13 from the first installation cavity.

[0065] Specifically, since the power supply and control module of the control component 5 involve the operation of multiple circuit boards, when the heating coil 3 is heating, the high temperature heat it generates may easily cause damage to the power supply and control module due to excessive heat; therefore, the power supply and control module are built into the second installation cavity 13, separated from the first installation cavity, and a partition 14 is provided between the first installation cavity and the second installation cavity 13. Thus, when the heating coil 3 is heating, most of the high temperature heat it generates is difficult to transfer to the second installation cavity 13.

[0066] According to the attached Figure 2 As shown, in a further embodiment, a plurality of ventilation holes 15 are provided on the side wall of the body case 1, all of which are connected to the second installation cavity 13. Specifically, in order to prevent heat accumulation in the second installation cavity 13, a plurality of ventilation holes 15 are provided on the side wall of the body case 1, all of which are connected to the second installation cavity 13. When the heating coil 3 generates heat, part of the heat is transferred to the second installation cavity 13. At the same time, when the power supply and the control module are in operation, the heat generated by the two can be dissipated from the plurality of ventilation holes 15, thereby preventing heat accumulation in the second installation cavity 13.

[0067] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
