[0035] The utility model provides a heating device.

[0036] In the prior art, the production of heaters on the production line requires the use of nickel wire and soldering technology to achieve electrical connection. However, the soldering process often has problems such as poor welding and long welding time, resulting in production capacity not meeting standards.

[0037] In order to solve the above technical problems, the technical solution of the utility model adopts a heating body to set a connecting pin, and the connecting pin extends out of the shell, so that the connecting pin and the adapter can be directly electrically connected through the first connecting member, and the adapter and the mainboard can be electrically connected through the second connecting member, so as to further realize the electrical connection between the mainboard and the heating body, and control the heating of the heating body. Therefore, the first connecting member and the second connecting member can replace the soldering of the heating device in production, which can effectively simplify the structural design, make the overall assembly design of the product more concise and fast, and save the process of soldering on the production line, greatly improving the production efficiency.

[0038] The above technical solution is described in detail below with reference to the accompanying drawings.

[0039] In the embodiment of the present utility model, Figures 1 to 5As shown, the heating device includes: a housing 100, a heating body 200, a mainboard 300, a connecting assembly 400, and an adapter 600. The heating body 200 is arranged in the housing 100, and the heating body 200 has a connecting pin 210, and the connecting pin 210 extends out of the housing 100. The mainboard 300 is arranged outside the housing 100, and the connecting assembly 400 includes a first connecting member 410 and a second connecting member 420 that are electrically connected. The first connecting member 410 is arranged between the adapter 600 and the connecting pin 210, and electrically connects the adapter 600 and the connecting pin 210 respectively. The second connecting member 420 is arranged between the adapter 600 and the mainboard 300, and electrically connects the adapter 600 and the mainboard 300 respectively.

[0040] In this embodiment, the housing 100 is arranged around the outer periphery of the heating body 200. The heating body 200 also has a heating tube and a heating film. The heating film is wrapped around the outer periphery of the heating tube. One end of the connecting pin 210 is connected to the heating film, and the other end extends toward one end of the housing 100 close to the adapter 600 and extends out of the housing 100. The main board 300 is used to control the heating process of the heating body 200. The adapter 600 electrically connects the main board 300 and the heating body 200 respectively, thereby realizing the electrical connection between the main board 300 and the heating body 200. It can be understood that there are two first connectors 410 and two second connectors 420, one of which is a positive electrode and the other is a negative electrode; one of which is a positive electrode and the other is a negative electrode.

[0041] Specifically, the first connecting member 410 is located between the adapter 600 and the connecting pin 210, and enables electrical connection between the adapter 600 and the connecting pin 210. The second connecting member 420 is located between the adapter 600 and the main board 300, and enables electrical connection between the adapter 600 and the main board 300. In this way, the main board 300 and the connecting pin 210 are electrically connected through the first connecting member 410 and the second connecting member 420, and then the main board 300 can control the heating of the heating body 200, so that the overall structural design is simple and the production process is relatively simple. Furthermore, the present embodiment also extends out of the shell 100 through the connecting pin 210, and can be directly electrically connected to the first connecting member 410 on the outside of the shell 100 without extending to the inside of the shell 100 through an electrical connecting line. In addition, the present embodiment replaces the nickel wire in the current heating device with the first connecting member 410 and the second connecting member 420 to achieve electrical connection through the soldering process, thereby simplifying the entire assembly design of the product, eliminating the soldering process, avoiding the problems of poor welding and long welding time caused by soldering, and thus improving production capacity.

[0042] Optionally, the adapter 600 and one of the connecting pins 210 are provided with a first connecting member 410, and the first connecting member 410 is in contact and connected with the other one of the connecting pins 210 of the adapter 600, and the adapter 600 and one of the mainboard 300 are provided with a second connecting member 420, and the second connecting member 420 is in contact and connected with the other one of the connecting pins 210 of the adapter 600 and the mainboard 300.

[0043] In the specific implementation process, in order to simplify the overall structural design, in this embodiment, the end of the connecting pin 210 away from the heating body 200 is bent and bonded to the housing 100, the first connecting member 410 is fixed on the adapter 600, and the adapter 600 is located outside the housing 100 and close to the housing 100 so that the first connecting member 410 is in contact with the connecting pin 210, thereby realizing the electrical connection between the connecting pin 210 and the adapter 600. The main board 300 is located below the outside of the housing 100, the second connecting member 420 is fixed on the main board 300, and the lower part of the adapter 600 is close to the main board 300 and in contact with the second connecting member 420, thereby realizing the electrical connection between the adapter 600 and the adapter 600.

[0044] Furthermore, the first connecting member 410 and / or the second connecting member 420 is a spring structure. The spring structure has a certain elasticity, and the spring structure is made of a conductive metal material, so that the spring structure always maintains contact connection by relying on its own elasticity. Figure 4 As shown, the spring structure includes a base 700 and an elastic arm 710. One end of the elastic arm 710 is connected to the base 700, and the other end is bent toward the base 700 to form a support arm 720. The elastic arm 710 is provided with a contact portion 711, which is used for contact connection.

[0045] In the specific implementation process, the base 700, the elastic wall and the support arm 720 are an integrated structure, which simplifies the production process. In this embodiment, the first connecting member 410 is a spring structure, the base 700 is a plate-like structure, one end of the base 700 is bent twice and extends toward the other end of the base 700 to form an elastic arm 710, and the elastic arm 710 is bent twice to form a contact portion 711 protruding away from the base 700, and the elastic arm 710 is also bent toward the base 700 to form a support arm 720, and the end of the support arm 720 is bent toward the elastic arm 710, and the bending part is used to contact the base 700 to play a supporting role. The base 700 is fixedly connected to the adapter 600, and the contact portion 711 is used to contact the connecting pin 210. Specifically, when the contact portion 711 contacts the connecting pin 210, the elastic arm 710 and the support arm 720 are compressed. Due to the elastic effect, the contact portion 711 is always in close contact with the connecting pin 210. In addition, both sides of the base 700 are bent toward the support arm 720 to form a panel structure to protect the support arm 720, and also play a role in limiting and guiding the support arm 720, so as to prevent the support arm 720 from being offset when being compressed and causing the contact portion 711 to be unable to contact the corresponding position. It can be understood that in another embodiment, the second connecting member 420 is also a spring structure, please refer to the description of the first connecting member 410, which will not be described in detail here. The base 700 of the second connecting member 420 is fixedly connected to the main body, and the contact portion 711 is closely connected to the adapter 600.

[0046] like Figure 2 and Figure 5 As shown, optionally, the heating device also includes a support frame 800, which is connected to the shell 100, and the adapter 600 includes a first bending portion 610 and a second bending portion 620, the first bending portion 610 is bonded to the side of the support frame 800 facing the shell 100, the first bending portion 610 is provided with a first connecting member 410 and is in contact with the connecting pin 210, the second bending portion 620 is bonded to the side of the support frame 800 facing the main board 300, and the main board 300 is provided with a second connecting member 420 and is in contact with the second bending portion 620.

[0047] In this embodiment, the support frame 800 is installed on the outside of the housing 100, and the adapter 600 is fixed on the support frame 800. The support frame 800 supports the adapter 600, wherein the first bending portion 610 and the second bending portion 620 are bonded to the support frame 800 by double-sided adhesive. Specifically, the adapter 600 includes a main body, one end of the main body is bent at both sides to form a first bending portion 610, and the first bending portion 610 extends away from the end of the main body toward the other end of the main body, and the support frame 800 is at least partially located between the main body and the first bending portion 610, so that the side of the first bending portion 610 opposite to the main body is bonded to the support frame 800. The first connecting member 410 is fixed on the side of the first bending portion 610 facing the housing 100, and the support frame 800 is fixedly connected to the housing 100, so that the first connecting member 410 is in contact with and connected to the connecting pin 210 extending out of the housing 100. One end of the main body away from the first bending portion 610 is bent to form a second bending portion 620, and the second bending portion 620 is bonded to the outer wall of the support frame 800 facing the main board 300. The second connecting member 420 on the main board 300 is arranged opposite to the second bending portion 620 and is in contact and connected with the second connecting member 420.

[0048] In the specific implementation process, the adapter 600 can be a structure such as a nickel wire or a circuit board, which can realize the electrical connection between the mainboard 300 and the heating body 200. Furthermore, in the present embodiment, the adapter 600 is a flexible circuit board. The use of a flexible circuit board can simplify the structural design and facilitate the bending layout. At the same time, it can be understood that the nickel wire will vibrate when it is energized, and vibration will generate noise. In the present embodiment, a flexible circuit board is used to realize the electrical connection between the mainboard 300 and the heating body 200. The structural design without nickel wire can solve the noise problem caused by the vibration of the nickel wire when it is energized from the root, and there is no need for glue fixation. In addition, patches are electrically connected to the flexible circuit board and the connecting pins 210, and the first connector 410 and the second connector 420 are respectively in contact with the patches to realize electrical connection.

[0049] In this embodiment, the support frame 800 has a positioning column 810, and the flexible circuit board is provided with a positioning hole 630. The positioning column 810 is arranged in cooperation with the positioning hole 630. The housing 100 is also provided with a positioning groove 110. The positioning column 810 passes through the positioning hole 630 and is inserted into the positioning groove 110. There are two positioning columns 810. In order to facilitate the processing of the flexible circuit board, the positioning holes 630 are located on the opposite side edges of the flexible circuit board, and the connection line between the two positioning holes 630 intersects with the lateral direction of the flexible circuit board to avoid the flexible circuit board from tilting, which is convenient for positioning and production operations. In addition, the outer side of the housing 100 is correspondingly provided with a positioning groove 110. The positioning column 810 passes through the positioning hole 630 and is inserted into the positioning groove 110, which is convenient for the positioning and installation of the support frame 800, and further ensures that the first connector 410 on the adapter 600 quickly and accurately contacts the connecting pin 210.

[0050] Optionally, the heating device further comprises a support seat 900, the support seat 900 is connected to the housing 100, the main board 300 is connected to the support seat 900, the support seat 900 is provided with a guard plate 910, and the adapter 600 is arranged between the guard plate 910 and the housing 100. In the specific implementation process, the main board 300 is fixed to the support seat 900 by connecting members such as screws, and the second connecting member 420 is fixed to the side of the main board 300 facing the adapter 600. The support seat 900 is fixed to the outside of the housing 100. In addition, the main body of the adapter 600 also extends along the guard plate 910, and the guard plate 910 surrounds the outer periphery of the support frame 800 and the housing 100 close to one end of the support frame 800, so as to protect the adapter 600.

[0051] Alternatively, if Figure 2 and Figure 3 As shown, the heating body 200 is formed with a heating chamber 220, and the heating device also includes a temperature sensor 500, which is arranged on the housing 100 and is used to sense the temperature in the heating chamber 220, and the temperature sensor 500 is electrically connected to the adapter 600.

And, further, the receiving groove is arranged opposite to the heating chamber 220, so that the temperature sensor 500 can sense the temperature in the heating chamber 220. The temperature sensor 500 is also electrically connected to the main board 300 through the adapter 600, so that the temperature in the heating chamber 220 can be sensed through the temperature sensor 500, which is convenient for the main board 300 to control the heating of the heating element.
