Description

Technical Field

[0001] This utility model relates to the field of electric heating insulation board technology, and in particular to a self-controlled constant temperature electric heating insulation board. Background Technology

[0002] Electric heating insulation board is a type of insulation device that uses electrical energy to convert into heat energy. It is commonly used in food insulation, laboratory instrument temperature control, or medical insulation. Its core function is to maintain the surface or internal temperature of an object through stable heating and prevent heat loss.

[0003] Currently, common electric heating insulation boards typically employ a built-in heating wire design. The heating wire is embedded inside the insulation board, and heat is evenly conducted to the surface of the object being heated through the metal or ceramic heat-conducting plate on top. This structure can effectively reduce local overheating, improve thermal efficiency, and make the surface of the insulation board smoother and more durable, meeting various usage needs.

[0004] However, once the insulation plate with built-in heating wire is damaged, the repair process is often quite complicated. Since the heating wire is hidden under the heat-conducting plate, users need to remove the heat-conducting plate first to expose the heating wire for inspection or replacement. Currently, most heat-conducting plates are fixed to the outer shell with multiple sets of screws. When disassembling, tools such as screwdrivers must be used to unscrew them one by one. The process is complicated and time-consuming. This design not only increases the difficulty of maintenance but also reduces the ease of use of the product. Therefore, a self-controlled constant temperature electric heating insulation plate is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 One embodiment of this utility model is a self-controlled constant temperature electric heating insulation board, which includes a heating base 1 and a heat-conducting cover 2. The heat-conducting cover 2 is snapped onto the outer wall of the heating base 1. The side walls of the heating base 1 and the heat-conducting cover 2 are provided with a disassembly and assembly mechanism 3 and a lifting mechanism 4.

[0032] Reference Figures 2-3, the disassembly and assembly mechanism 3 includes a fixing plate 31, which is fixedly installed at the bottom of the heat conduction cover 2. Through the fixing plate 31, the heat conduction cover 2 can be limited above the heating base 1. An inclined slot 32 and a straight slot 33 are provided on the fixing plate 31. The straight slot 33 is located above the inclined slot 32. The inclined slot 32 is inclined on the fixing plate 31. Both the bottom end and the top end of the inclined slot 32 are open, and the opening at the top end of the inclined slot 32 is communicated with the inside of the straight slot 33. The bent rod 35 can be guided through the inclined slot 32, so that the bent rod 35 can enter the inside of the straight slot 33 along the inclined slot 32. A slider 34 is slidably connected to the side wall of the heating base 1. A bent rod 35 is penetrated and slidably connected to the inner wall of the slider 34. The bent rod 35 is in a "C" - shaped structure. A limiting spring 36 is fixedly installed on the inner wall of the slider 34. One end of the bent rod 35 extends into the inside of the straight slot 33. The convex block 41 can be limited by the cooperation of the bent rod 35 and the straight slot 33. The other end of the bent rod 35 is fixedly installed with the limiting spring 36. The limiting spring 36 can pull the bent rod 35 to slide and reset on the inner wall of the slider 34. A positioning spring 37 is fixedly installed on the outer wall of the slider 34. The end of the positioning spring 37 far from the slider 34 is fixedly installed on the inner wall of the heating base 1. By pushing the slider 34 with the positioning spring 37, the slider 34 can slide and reset on the side wall of the heating base 1.

[0033] Refer to Figures 2-3 , the lifting mechanism 4 includes a convex block 41, which is fixedly installed on the side wall of the heat conduction cover 2. Through the convex block 41, the heat conduction cover 2 can be driven to slide upward on the outer wall of the heating base 1. An inclined surface 42 is provided on the side of the convex block 41 close to the heat conduction cover 2. A ball - head rod 43 is penetrated and slidably connected to the inner wall of the bent rod 35. By sliding the ball - head rod 43 upward, the convex block 41 can be pushed upward, and then the heat conduction cover 2 can be lifted upward so that the user can separate the heat conduction cover 2 from the heating base 1. One end of the ball - head rod 43 is fitted to the outer wall of the inclined surface 42. When the convex block 41 is in a fixed state, when the bent rod 35 drives the ball - head rod 43 to move, the ball - head rod 43 will be squeezed by the inclined surface 42. A return spring 44 is fixedly installed at the other end of the ball - head rod 43. The end of the return spring 44 far from the ball - head rod 43 is fixedly installed on the inner wall of the bent rod 35. The return spring 44 can push the ball - head rod 43 upward, so that the ball - head rod 43 slides upward on the inner wall of the bent rod 35.

[0034] Working principle: When in use, when it is necessary to repair or replace the heating wire inside the heating base 1, only need to pull the bent rod 35 to gradually slide out of the outside of the slider 34. At the same time, the bent rod 35 will stretch the limiting spring 36 and gradually move out of the inside of the straight slot 33. When the bent rod 35 completely moves out of the inside of the straight slot 33, the limit on the fixing plate 31 can be released, and thus the fixing of the heat conduction cover 2 can be released. Just lift the heat conduction cover 2 upward to separate it from the heating base 1, making the disassembly of the heat conduction cover 2 more convenient.

[0035] When it is necessary to reinstall the disassembled heat-conducting cover 2 back onto the heating base 1, align the heat-conducting cover 2 with the heating base 1 and press it downwards. At this time, the heat-conducting cover 2 will drive the fixing plate 31 to move downwards synchronously. During the downward movement of the fixing plate 31, the inclined groove 32 will squeeze the bent rod 35, causing the bent rod 35 to push the slider 34. At this time, the slider 34 will slide on the side wall of the heating base 1 and compress the positioning spring 37. Meanwhile, as the fixing plate 31 continues to move downwards, the bent rod 35 will gradually move into the straight groove 33 while adhering to the inner wall of the inclined groove 32. When the bent rod 35 has completely moved into the straight groove 33... After the inside of the groove 32 is squeezed, the bent rod 35 stops pushing the slider 34. At this time, the positioning spring 37 pushes the slider 34, causing the slider 34 to slide on the side wall of the heating base 1. At the same time, the slider 34 will drive the bent rod 35 to move synchronously during the sliding process, so that the bent rod 35 can be inserted into the inside of the straight groove 33. When the bent rod 35 is inserted into the inside of the straight groove 33, it will limit the fixing plate 31, thereby fixing the heat-conducting cover 2 above the heating base 1, thus completing the installation of the heat-conducting cover 2. Compared with the screw fixing method, the installation is more convenient.

[0036] When the bent rod 35 is pulled out of the straight groove 33 and the limiting spring 36 is stretched, the bent rod 35 will drive the ball head rod 43 to move synchronously. During this process, when the bent rod 35 has not yet moved out of the straight groove 33, the cooperation between the bent rod 35 and the straight groove 33 will still limit the fixing plate 31, so that the heat conduction cover 2 is still in a fixed state. The fixed state of the heat conduction cover 2 will cause the protrusion 41 to remain in a fixed state. As the bent rod 35 drives the ball head rod 43 to continue to move, the ball head rod 43 will be squeezed by the inclined plate 42 and move downward on the inner wall of the bent rod 35 while compressing the return spring 44. When the bent rod 35 is completely removed from the inside of the straight groove 33 during the movement, the bent rod 35 will release the limiting effect on the fixing plate 31, thereby releasing the fixing effect on the heat conduction cover 2. At this time, the return spring 44 will push the ball head rod 43 upward, so that the ball head rod 43 slides upward on the inner wall of the bent rod 35. While the ball head rod 43 slides upward, it will push the protrusion 41 upward, so that the protrusion 41 will drive the heat conduction cover 2 to move upward on the outer wall of the heating base 1, thereby lifting the heat conduction cover 2 upward so that the user can separate the heat conduction cover 2 from the heating base 1, further facilitating the disassembly of the heat conduction cover 2.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
