[0050] Embodiment 1

[0051] This embodiment provides a heating element assembly 100, including a frame assembly, a heating element 2, and elastic pole pieces 3. Among them: the frame assembly has a heat transfer surface 102 and a support surface arranged opposite to each other; the heating element 2 is arranged between the heat transfer surface 102 and the support surface; two electrodes 201 are arranged on the same side of the heating element 2, and the other side of the heating element 2 can be in complete contact with the heat transfer surface 102; there are two elastic pole pieces 3, and each elastic pole piece 3 is arranged between the electrode 201 of the heating element 2 and the support surface, and the two elastic pole pieces 3 are respectively in contact with the two electrodes 201 of the heating element 2. In this embodiment, the two electrodes 201 of the heating element 2 are arranged on the same side surface of the heating element 2, so that the two elastic pole pieces 3 connected to the two electrodes 201 of the heating element 2 can be arranged on the same side of the heating element 2, and the side surface of the heating element 2 far from the electrode 201 can be in direct and complete contact with the first heat transfer body 1, which is beneficial to improving the heat transfer efficiency.

[0052] In some specific embodiments, the heating element 2 is a thermistor, preferably a PTC thermistor.

[0053] In some specific embodiments, the surface of the first heat transfer body 1 close to the elastic pole piece 3 is the heat transfer surface 102, and the surfaces of the heating element 2 far from the elastic pole piece 3 and the heat transfer surface 102 are both flat surfaces. The surface where the first heat transfer body 1 and the heating element 2 are in contact with each other is set as a flat surface, which is convenient for processing and ensuring the processing accuracy, so as to ensure that the first heat transfer body 1 and the heating element 2 can be in complete contact. The heat transfer surface 102 needs to ensure flatness without sand grains and air holes to avoid affecting the temperature consistency of the heating element 2; since the heat transfer surface 102 of the first heat transfer body 1 is arranged on the outside, it is convenient for processing.

[0054] In some specific embodiments, the heating element 2 is generally processed by cutting and grinding, and the heat transfer surface 102 of the heating element 2 can meet the heat conduction requirements. The two elastic pole pieces 3 need to have a sufficient elastic interference amount, and the elastic pole pieces 3 have sufficient elastic force to hold the heating element 2 (the elastic pole pieces 3 also play a conductive role at the same time), so that the heating element 2, the two elastic pole pieces 3, and the first heat transfer body 1 are completely attached.

[0055] In some specific embodiments, the elastic pole piece 3 adopts an S-shaped structure. After the heating element 2 is assembled, the elastic pole piece 3 will be compressed, so that the elastic pole piece 3 is in good contact with the heating element 2, and the heating element 2 is in complete contact with the first heat transfer body 1.

[0056] Embodiment 2

[0057] As Figures 1 - 5As shown in the figure, this embodiment provides a heating element assembly 100. Both ends of each elastic pole piece 3 are respectively in contact with the heating element 2 and the support surface, and the heating element 2 is pressed against the heat transfer surface 102 through the elastic pole piece 3. By inserting the heating element 2 and the elastic pole piece 3 between the heat transfer surface 102 and the support surface, under the elastic force of the elastic pole piece 3, the connection of the heating element 2, the elastic pole piece 3 and the frame assembly or the installation of the elastic pole piece 3 can be realized. The structure is simple and the installation is convenient.

[0058] In some specific embodiments, the frame assembly includes a first heat transfer body 1 and a first frame 4, and the first frame 4 has a support surface; the first heat transfer body 1 is used to be arranged on the side of the first frame 4 away from the support surface, and the first heat transfer body 1 can be fixedly connected to the first frame 4; the surface of the first heat transfer body 1 close to the support surface is the heat transfer surface 102.

[0059] In some specific embodiments, a second installation hole 401 is provided on the side of the first frame 4 close to the first heat transfer body 1. The heat conducting member 5 is riveted in the first installation hole 101 of the first heat transfer body 1 and the second installation hole 401 of the first frame 4, and the heat conducting member 5 can fix the first heat transfer body 1 on the first frame 4. Specifically, the heat conducting member 5 is sequentially passed through the first installation hole 101 and the second installation hole 401, and the two ends of the heat conducting member 5 are deformed by hammering, press riveting or blind riveting, so as to fix the first heat transfer body 1 on the first frame 4, ensuring the stability of the installation. After the heat on the heating element 2 is conducted to the first heat transfer body 1, the heat of the first heat transfer body 1 can be conducted to the heat conducting member 5, so that the heating element assembly 100 obtains the required temperature.

[0060] In some specific embodiments, a first installation groove 402 is provided on the side of the first frame 4 away from the first heat transfer body 1. The opening of the first installation groove 402 faces the first heat transfer body 1, and the inner bottom wall of the first installation groove 402 is the support surface; two first through holes communicating with the first installation groove 402 are provided on the inner bottom wall of the first installation groove 402. One end of each elastic pole piece 3 is arranged in the first installation groove 402, and the other ends of the two elastic pole pieces 3 respectively extend out of the first installation groove 402 through the two first through holes. The other ends of each elastic pole piece 3 are used for fixedly connecting with a wire; the heating element 2 is arranged in the first installation groove 402. By integrally wrapping and fixing the heating element 2 in the first installation groove 402 of the first frame 4, it is ensured that the heating element 2 can stably transfer heat, so that the heating element 2 conducts heat to the first heat transfer body 1 as much as possible.

[0061] In some specific embodiments, the heat conducting member 5 is an aluminum tube. It should be noted that the heat conducting member 5 is not limited to using an aluminum tube, and can also be other metal tube bodies such as an iron tube.

[0062] As a preferred embodiment, the first heat transfer body 1 of this embodiment is a ceramic body. It should be noted that the material of the first heat transfer body 1 in this embodiment is not limited to ceramics, and insulating materials such as plastics that can meet the heat transfer requirements can also be used for replacement. When the first heat transfer body 1 is a plastic body, metal sheets can be provided inside the plastic body to increase its thermal conductivity.

[0063] In some specific embodiments, the first frame 4 is a bipod.

[0064] Other structures, connection relationships, or setting methods of this embodiment are the same as those of Embodiment 1.

[0065] Embodiment 3

[0066] Such as Figures 5 - 7 As shown, this embodiment provides a heating element assembly 100. The difference between this embodiment and Embodiment 2 is that:

[0067] The first heat transfer body 1 is snap-connected to the first frame 4, which improves the convenience of disassembly and assembly. In this embodiment, there is no need to provide an aluminum tube, and the structure is simple.

[0068] In some specific embodiments, at both the left and right ends of the opening of the first installation groove 402 of the first frame 4, there is provided a snap tooth 403. On both sides of one end of the first heat transfer body 1 close to the heat transfer surface 102, there is provided a snap groove 103. The two snap teeth 403 respectively extend into the two snap grooves 103, and each snap tooth 403 abuts against the inner wall of the corresponding snap groove 103 close to the first installation groove 402, thereby restricting the movement of the first heat transfer body 1 in the direction away from the first installation groove 402. Specifically, as Figure 8 As shown, by pressing the heating element 2 with the first heat transfer body 1, the heating element 2 is completely placed in the first installation groove 402 and presses the elastic pole piece 3. The first heat transfer body 1 is inserted downward from above the first frame 4, so that the snap groove 103 and the snap tooth 403 are snap-connected, thereby realizing the fixation of the first heat transfer body 1, and the heating element 2 and the elastic pole piece 3 are pressed against the inner wall of the first installation groove 402 away from the first heat transfer body 1 by the first heat transfer body 1.

[0069] Embodiment 4

[0070] Such as Figures 10 - 12 As shown, this embodiment provides a heating element assembly 100. The frame assembly includes an installation frame 13. On one side of the installation frame 13, there is provided a second installation groove 15. The two opposite inner side walls of the second installation groove 15 are respectively a heat transfer surface 102 and a support surface.

[0071] In some specific embodiments, the frame assembly further includes a metal ring 14. On the side of the installation frame 13 away from the second installation groove 15, there is provided a second through hole. The metal ring 14 is embedded in the installation frame 13, and the metal ring 14 is arranged on the outer ring of the second through hole.

[0072] In some specific embodiments, two third through holes communicating with the second installation groove 15 are provided on the support surface. One end of each elastic pole piece 3 is arranged in the second installation groove 15, and the other ends of the two elastic pole pieces 3 respectively extend out of the second installation groove 15 through the two third through holes. The other ends of the elastic pole pieces 3 are used for fixedly connecting with wires; the heating element 2 is arranged in the second installation groove 15.

[0073] Other structures, connection relationships, setting manners, etc. of this embodiment are the same as those of Embodiment 1.

[0074] Embodiment 5

[0075] As Figure 15 shown, this embodiment provides a heating element assembly 100, in which the heating element 2 is fixedly connected to the heat transfer surface 102, and both ends of each elastic pole piece 3 are respectively in contact with the heating element 2 and the support surface.

[0076] In some specific embodiments, the heating element 2 is injection-molded on the mounting frame 13. Specifically: taking the mounting frame 13 as an insert, the heating element 2 is injection-molded on an inner side wall of the second installation groove 15 of the mounting frame 13, so that the two electrodes 201 of the heating element 2 are located on the side of the heating element 2 away from this inner side wall.

[0077] In some specific embodiments, the mounting frame 13 is a two-leg frame, and the material can be ceramic or plastic. When the material of the two-leg frame is plastic, a metal ring can be embedded in the two-leg frame to increase the thermal conductivity.

[0078] Other structures, connection relationships, setting manners, etc. of this embodiment are the same as those of Embodiment 4.

[0079] Embodiment 6

[0080] As Figure 16 shown, this embodiment provides a heating element assembly 100, one end of each elastic pole piece 3 is fixedly connected to the support surface, and the other end of each elastic pole piece 3 is in contact with the heating element 2 and presses the heating element 2 against the heat transfer surface 102.

[0081] In some specific embodiments, each elastic pole piece 3 is injection-molded on the mounting frame 13. Specifically: taking the mounting frame 13 as an insert, the elastic pole piece 3 is injection-molded on an inner side wall of the mounting frame 13.

[0082] In some specific embodiments, the mounting frame 13 is a two-leg frame, and the material can be ceramic or plastic. When the material of the two-leg frame is plastic, a metal ring can be embedded in the two-leg frame to increase the thermal conductivity.

[0083] Other structures, connection relationships, setting manners, etc. of this embodiment are the same as those of Embodiment 4.

[0084] Example 7

The two inner side walls of the third installation groove 1601 that are oppositely arranged are a heat transfer surface 102 and a support surface respectively.

[0086] The second heat transfer body 16 of this embodiment is a ceramic body. It should be noted that the material of the second heat transfer body 16 in this embodiment is not limited to ceramics, and plastics or other insulating materials that can meet the heat transfer requirements can also be used for substitution. When the second heat transfer body 16 is a plastic body, metal sheets can be provided in the plastic body to increase its thermal conductivity.

[0087] In some specific embodiments, the first frame 4 is a bipod.

[0088] Other structures, connection relationships, or setting methods of this embodiment are the same as those of Embodiment 1.

[0089] Example 8

[0090] This embodiment provides an electric heating vaporizer 200, which includes a base 6, a face cover 7, an integrated switch 8, a plug socket assembly 9, and the heating element assembly 100 in Embodiments 1 to 7. The heating element assembly 100 is fixedly connected to the base 6; the face cover 7 can be fixedly connected to the base 6; the integrated switch 8 is fixedly connected to the base 6, and the integrated switch 8 is electrically connected to the heating element assembly 100, preferably electrically connected through a first wire 11; the plug socket assembly 9 is arranged on the base 6, and the plug socket assembly 9 is electrically connected to the integrated switch 8, preferably electrically connected through a second wire 12. A button 10 is provided on the integrated switch 8. Through the button 10, the opening and closing of the integrated switch 8 can be controlled, and thus the opening and closing of the electric heating vaporizer 200 can be controlled.

[0091] The electric heating vaporizer 200 of this embodiment is an electric mosquito repellent device or an electric perfume diffuser or other devices that use electric energy to heat and quickly volatilize or vaporize substances.

[0092] Example 9

[0093] This embodiment provides a heating element assembly process based on the heating element assembly 100 in Embodiment 2, including the following steps:

[0094] Install the heating element 2 and the elastic pole pieces 3 on the frame assembly, so that the side of the heating element away from the electrode 201 is in full contact with the heat transfer surface 102, and the two elastic pole pieces 3 are respectively in contact with the two electrodes 201 on the same side of the heating element 2.

[0095] In some specific embodiments (for the heating element assembly 100 in Embodiment 2), the two elastic poles 3 are brought into contact with the two electrodes 201 of the heating element 2. The heating element 2 and the two elastic poles 3 are inserted between the heat transfer surface 102 and the support surface, and each elastic pole 3 is compressed so that both ends of each elastic pole 3 are respectively abutted against the support surface and the heating element 2, and the elastic pole 3 presses the heating element 2 tightly against the heat transfer surface 102. Then, the first frame 4 and the first heat transfer body 1 are riveted through the heat conducting member 5, making the whole heating element 2 more reliable, and then a wire is connected to the elastic pole 3.

[0096] In some specific embodiments, it further includes: loading the heating element 2 and the two elastic poles 3 into the first installation groove 402 of the first frame 4, then squeezing the heating element 2 and the elastic poles 3 through the first heat transfer body 1 to align the through hole on the first heat transfer body 1 with that on the first frame 4. Then, an aluminum tube is inserted into the through holes on the first heat transfer body 1 and the first frame 4, and the first frame 4, the first heat transfer body 1 and the first frame 4 are riveted through the aluminum tube. At the same time, wires can be connected to the two electrodes 201 by means of riveting, plugging (terminal plugging or direct plugging), spot welding, wrapping, etc. Preferably, the riveting, plugging and wrapping methods are used for connection, and there is no need to use an automatic PTC wire welding machine for welding, which is beneficial to reducing energy consumption and manufacturing costs. The whole process can be automatically assembled at one time by using automated equipment. Most of the heating element assemblies 100 of the traditional electric evaporator 200 are processed by the ceramic potting process, and its manufacturing method is as follows: First, two wires are welded to the two poles of the heating element 2. Second, an appropriate amount of glue is poured into the first heat transfer body 1, and the welded heating element 2 is inserted into the glue in the first heat transfer body 1 to form a semi-finished product. Third, the semi-finished product is put into an oven for drying. Fourth, the dried first heat transfer body 1 is riveted with a plastic two-legged frame and an aluminum tube to form a finished heating element 2. The process of the traditional heating element assembly 100 is relatively cumbersome and has many processing steps. In addition, the temperature uniformity of the heating element assembly 100 is the most important technical parameter of the electric evaporator 200. The temperature uniformity of the traditional heating element assembly 100 depends on various factors such as the temperature error of the heating element 2, the formula of the glue, and the drying process. It is difficult to control the temperature uniformity of the traditional heating element assembly 100. However, the installation process of this embodiment does not require glue, and the temperature uniformity is no longer affected by the formula of the glue and the drying process. As long as it is ensured that the heating element 2 is completely attached to the two elastic poles 3 and the heating element 2 is completely attached to the first heat transfer body 1, the temperature uniformity of the heating element 2 can be ensured (a heat conducting material such as thermal grease can be applied between the heating element 2 and the first heat transfer body 1 to achieve a better heat transfer effect). The manufacturing process is relatively simple, with fewer control points, improving the temperature uniformity of the heating element assembly 100. There is no need to use an oven for drying, which is beneficial to reducing energy consumption and manufacturing costs.
