[0048] The purpose of this invention is to provide a heating element assembly, an electrothermal evaporator, and a heating element assembly process to solve the problems existing in the prior art and improve heat transfer efficiency.

[0049] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] This embodiment provides a heating element assembly 100, including a frame assembly, a heating element 2, and elastic electrodes 3. The frame assembly has a heat transfer surface 102 and a supporting surface arranged opposite to each other. The heating element 2 is disposed between the heat transfer surface 102 and the supporting surface. Two electrodes 201 are disposed on the same side of the heating element 2, and the other side of the heating element 2 can fully contact the heat transfer surface 102. Two elastic electrodes 3 are provided, each disposed between the electrode 201 of the heating element 2 and the supporting surface, and each of the two elastic electrodes 3 is in contact with the two electrodes 201 of the heating element 2. This embodiment places the two electrodes 201 of the heating element 2 on the same side of the heating element 2, allowing the two elastic electrodes 3 connected to the two electrodes 201 of the heating element 2 to be disposed on the same side of the heating element 2. The side of the heating element 2 away from the electrodes 201 can directly and fully contact the first heat transfer element 1, which is beneficial for improving 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 element 1 near the elastic electrode 3 is the heat transfer surface 102, and both the surface of the heating element 2 away from the elastic electrode 3 and the heat transfer surface 102 are planar. The planar design of the contact surfaces between the first heat transfer element 1 and the heating element 2 facilitates processing and ensures processing accuracy, thereby guaranteeing complete contact between the first heat transfer element 1 and the heating element 2. The heat transfer surface 102 must be flat and free of sand particles and pores to avoid affecting the temperature uniformity of the heating element 2; since the heat transfer surface 102 of the first heat transfer element 1 is located on the outer side, it facilitates 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 plates 3 need to have sufficient elastic interference, and the elastic plates 3 have sufficient elastic force to hold the heating element 2 (the elastic plates 3 also play a conductive role), so that the heating element 2, the two elastic plates 3, and the first heat transfer element 1 are completely in contact.

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

[0056] Example 2

[0057] like Figures 1-5As shown, this embodiment provides a heating element assembly 100, with each elastic electrode 3 having its two ends abutting against the heating element 2 and the supporting surface, respectively. The heating element 2 is pressed against the heat transfer surface 102 by the elastic electrode 3. By inserting the heating element 2 and the elastic electrode 3 between the heat transfer surface 102 and the supporting surface, the connection of the heating element 2, the elastic electrode 3, and the frame assembly or the installation of the elastic electrode 3 can be achieved under the elastic force of the elastic electrode 3. The structure is simple and easy to install.

[0058] In some specific embodiments, the frame assembly includes a first heat transfer element 1 and a first frame 4, the first frame 4 having a support surface; the first heat transfer element 1 is disposed on the side of the first frame 4 away from the support surface, and the first heat transfer element 1 can be fixedly connected to the first frame 4; the surface of the first heat transfer element 1 near the support surface is a heat transfer surface 102.

[0059] In some specific embodiments, a second mounting hole 401 is provided on the side of the first frame 4 near the first heat transfer body 1. A heat-conducting element 5 is riveted into the first mounting hole 101 of the first heat transfer body 1 and the second mounting hole 401 of the first frame 4, and the heat-conducting element 5 can fix the first heat transfer body 1 onto the first frame 4. Specifically, the heat-conducting element 5 is passed sequentially through the first mounting hole 101 and the second mounting hole 401, and its ends are deformed by hammering, pressing, or pulling, thereby fixing the first heat transfer body 1 onto the first frame 4 and ensuring installation stability. After the heat from the heating element 2 is conducted to the first heat transfer body 1, the heat from the first heat transfer body 1 can be conducted to the heat-conducting element 5, so that the heating element assembly 100 reaches the required temperature.

[0060] In some specific embodiments, a first mounting 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 mounting groove 402 faces the first heat transfer body 1, and the inner bottom wall of the first mounting groove 402 serves as a support surface. Two first through holes communicating with the first mounting groove 402 are provided on the inner bottom wall of the first mounting groove 402. One end of each elastic electrode 3 is disposed in the first mounting groove 402, and the other ends of the two elastic electrodes 3 extend out of the first mounting groove 402 through the two first through holes respectively. The other end of each elastic electrode 3 is used for fixed connection with a wire. The heating element 2 is disposed in the first mounting groove 402. By completely enclosing and fixing the heating element 2 in the first mounting groove 402 of the first frame 4, stable heat transfer of the heating element 2 is ensured, allowing the heating element 2 to conduct heat to the first heat transfer body 1 as much as possible.

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

[0062] In a preferred embodiment, the first heat transfer element 1 is a ceramic body. It should be noted that the material of the first heat transfer element 1 in this embodiment is not limited to ceramic; it can also be replaced by insulating materials such as plastic that can meet the heat transfer requirements. When the first heat transfer element 1 is a plastic body, a metal sheet can be placed inside the plastic body to increase its thermal conductivity.

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

[0064] Other structures, connections, or configurations in this embodiment are the same as in Embodiment 1.

[0065] Example 3

[0066] like 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 element 1 is fastened to the first frame 4, which improves the convenience of disassembly and assembly. In this embodiment, there is no need to set up aluminum tubes, and the structure is simple.

[0068] In some specific embodiments, a snap-fit ​​tooth 403 is provided at both ends of the opening of the first mounting groove 402 of the first frame 4, and a snap-fit ​​groove 103 is provided on both sides of the end of the first heat transfer body 1 near the heat transfer surface 102. The two snap-fit ​​teeth 403 extend into the two snap-fit ​​grooves 103 respectively, and each snap-fit ​​tooth 403 abuts against the inner wall of the corresponding snap-fit ​​groove 103 near the first mounting groove 402, thereby restricting the movement of the first heat transfer body 1 away from the first mounting groove 402. Specifically, as shown in the figure... 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 mounting groove 402 and the elastic electrode 3 is squeezed. The first heat transfer body 1 is inserted downward from the top of the first frame 4, so that the fastening groove 103 and the fastening tooth 403 are fastened together, thereby fixing the first heat transfer body 1. The heating element 2 and the elastic electrode 3 are squeezed into the inner wall of the first mounting groove 402 away from the first heat transfer body 1 by the first heat transfer body 1.

[0069] Example 4

[0070] like Figures 10-12 As shown, this embodiment provides a heating element assembly 100. The frame assembly includes a mounting bracket 13. A second mounting groove 15 is provided on one side of the mounting bracket 13. The two inner sidewalls of the second mounting groove 15 are heat transfer surface 102 and support surface, respectively.

[0071] In some specific embodiments, the frame assembly also includes a metal ring 14. The mounting bracket 13 has a second through hole on the side away from the second mounting groove 15. The metal ring 14 is embedded in the mounting bracket 13 and is disposed on the outer ring of the second through hole.

[0072] In some specific embodiments, two third through holes communicating with the second mounting groove 15 are provided on the support surface. One end of each elastic electrode 3 is disposed in the second mounting groove 15, and the other end of the two elastic electrodes 3 extends out of the second mounting groove 15 through the two third through holes respectively. The other end of each elastic electrode 3 is used to fix and connect with the wire. The heating element 2 is disposed in the second mounting groove 15.

[0073] Other structures, connections, or configurations in this embodiment are the same as in Embodiment 1.

[0074] Example 5

[0075] like Figure 15 As 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 the two ends of each elastic electrode 3 abut against the heating element 2 and the support surface, respectively.

[0076] In some specific embodiments, the heating element 2 is injection molded onto the mounting bracket 13. Specifically, the mounting bracket 13 is used as an insert, and the heating element 2 is injection molded onto one inner sidewall of the second mounting groove 15 of the mounting bracket 13, so that the two electrodes 201 of the heating element 2 are placed on the side of the heating element 2 away from the inner sidewall.

[0077] In some specific embodiments, the mounting bracket 13 is a bipod, which can be made of ceramic or plastic. When the bipod is made of plastic, a metal ring can be embedded in the bipod to increase thermal conductivity.

[0078] Other structures, connections, or configurations in this embodiment are the same as in Embodiment 4.

[0079] Example 6

[0080] like Figure 16 As shown, this embodiment provides a heating element assembly 100, with one end of each elastic electrode 3 fixedly connected to the support surface, and the other end of each elastic electrode 3 abutting against the heating element 2 and pressing the heating element 2 onto the heat transfer surface 102.

[0081] In some specific embodiments, each elastic electrode 3 is injection molded onto the mounting frame 13. Specifically, the mounting frame 13 is used as an insert, and the elastic electrode 3 is injection molded onto one inner sidewall of the mounting frame 13.

[0082] In some specific embodiments, the mounting bracket 13 is a bipod, which can be made of ceramic or plastic. When the bipod is made of plastic, a metal ring can be embedded in the bipod to increase thermal conductivity.

[0083] Other structures, connections, or configurations in this embodiment are the same as in Embodiment 4.

[0084] Example 7

[0085] like Figures 17-19 As shown, this embodiment provides a heating element assembly 100. The frame assembly includes a second heat transfer element 16 and a second frame 17. The second heat transfer element 16 is fixedly connected to the second frame 17. A third mounting groove 1601 is provided on the second heat transfer element 16. The two inner sidewalls of the third mounting groove 1601 are respectively a heat transfer surface 102 and a support surface.

[0086] In this embodiment, the second heat transfer element 16 is a ceramic body. It should be noted that the material of the second heat transfer element 16 in this embodiment is not limited to ceramic; it can also be replaced by insulating materials such as plastic that can meet the heat transfer requirements. When the second heat transfer element 16 is a plastic body, a metal sheet can be placed inside the plastic body to increase its thermal conductivity.

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

[0088] Other structures, connections, or configurations in this embodiment are the same as in Embodiment 1.

[0089] Example 8

[0090] This embodiment provides an electric evaporator 200, including a base 6, a cover 7, an integrated switch 8, a plug assembly 9, and a heating element assembly 100 as described in embodiments 1-7. The heating element assembly 100 is fixedly connected to the base 6; the cover 7 is fixedly connected to the base 6; the integrated switch 8 is fixedly connected to the base 6 and electrically connected to the heating element assembly 100, preferably via a first wire 11; the plug assembly 9 is disposed on the base 6 and electrically connected to the integrated switch 8, preferably via a second wire 12. The integrated switch 8 is provided with a button 10, which controls the opening and closing of the integrated switch 8, thereby controlling the opening and closing of the electric evaporator 200.

[0091] The electric evaporator 200 in this embodiment is a device that uses electric energy to heat substances so that they can be rapidly volatilized or vaporized, such as an electric mosquito repellent or electric perfume heater.

[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] The heating element 2 and the elastic electrode 3 are mounted on the frame assembly, so that the side of the heating element away from the electrode 201 is in complete contact with the heat transfer surface 102, and the two elastic electrodes 3 respectively abut against 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 plates 3 are brought into contact with the two electrodes 201 of the heating element 2, the heating element 2 and the two elastic plates 3 are inserted between the heat transfer surface 102 and the support surface, and each elastic plate 3 is compressed so that the two ends of each elastic plate 3 abut against the support surface and the heating element 2 respectively, and the elastic plates 3 press the heating element 2 tightly on the heat transfer surface 102; then the first frame 4 is riveted to the first heat transfer element 1 through the heat-conducting component 5, so that the heating element 2 is more reliable as a whole, and then wires are connected to the elastic plates 3.

[0096] In some specific embodiments, the method further includes: inserting the heating element 2 and two elastic electrodes 3 into the first mounting groove 402 of the first frame 4; then pressing the heating element 2 and elastic electrodes 3 with the first heat transfer element 1 to align the first heat transfer element 1 with the through hole on the first frame 4; then inserting an aluminum tube into the through hole on the first heat transfer element 1 and the first frame 4; and riveting the first frame 4 to the first heat transfer element 1 and the first frame 4 using the aluminum tube. Simultaneously, wires can be connected to the two electrodes 201 by riveting, insertion (terminal insertion or direct insertion), spot welding, or wrapping. Riveting, insertion, and wrapping methods are preferred for connection, eliminating the need for an automatic PTC wire welding machine, which helps reduce energy consumption and manufacturing costs. The entire process can be automatically assembled in one go using automated equipment. Traditional electric evaporators 200 typically employ a ceramic potting process for their heating element assembly 100. The manufacturing method involves: first, welding two wires to the two poles of the heating element 2; second, filling a first heat transfer body 1 with a suitable amount of glue, then inserting the welded heating element 2 into the glue within the first heat transfer body 1 to form a semi-finished product; third, drying the semi-finished product in an oven; and fourth, riveting the dried first heat transfer body 1 to a plastic bipod and an aluminum tube to form the finished heating element 2. The traditional heating element assembly 100 process is relatively complex and involves numerous steps. Furthermore, the temperature consistency of the heating element assembly 100 is the most critical technical parameter of the electric evaporator 200. The temperature consistency of the traditional heating element assembly 100 depends on various factors, including the temperature error of the heating element 2, the glue formulation, and the drying process, making it difficult to control. The installation process in this embodiment does not require the use of glue, and the temperature consistency is no longer affected by the glue formula or drying process. As long as the heating element 2 is fully attached to the two elastic electrodes 3 and the first heat transfer element 1, the temperature consistency of the heating element 2 can be guaranteed (thermal conductive materials such as thermal grease can be applied between the heating element 2 and the first heat transfer element 1 to achieve better heat transfer effect). The manufacturing process is relatively simple, with fewer control points, which improves the temperature consistency of the heating element assembly 100. There is no need to use an oven for drying, which helps to reduce energy consumption and manufacturing costs.

[0097] Example 10

[0098] This embodiment provides a heating element assembly process based on the heating element assembly 100 in Embodiment 3, including the following steps:

[0099] Make the two elastic plates 3 contact the two electrodes 201 of the heating element 2, insert the heating element 2 and the two elastic plates 3 between the heat transfer surface 102 and the support surface, and compress each elastic plate 3 so that the two ends of each elastic plate 3 abut against the support surface and the heating element 2 respectively, and press the heating element 2 tightly on the heat transfer surface 102.

[0100] In some specific embodiments, the method further includes: pressing the heating element 2 with the first heat transfer body 1 so that the heating element 2 is completely placed in the first mounting groove 402 and the elastic electrode 3 is squeezed; inserting the first heat transfer body 1 downward from above the first frame 4 so that the fastening groove 103 and the fastening tooth 403 are fastened together, thereby fixing the first heat transfer body 1; and pressing the heating element 2 and the elastic electrode 3 on the inner wall of the first mounting groove 402 away from the first heat transfer body 1 through the first heat transfer body 1.

[0101] In some specific embodiments, wires can be connected to the two electrodes 201 by riveting, plugging (terminal plugging or direct plugging), spot welding, wrapping, etc. Riveting, plugging, and wrapping are preferred methods, eliminating the need for an automatic PTC wire welding machine, which helps reduce energy consumption and manufacturing costs. The entire process can be automated in one go using automated equipment.
