[0031] A temperature control switch device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 A temperature control switch device according to an embodiment of the utility model includes a box body 100, a buckle structure and a switch body 110. The buckle structure is arranged on the box body 100. The buckle structure is used to install the switch body 110. The switch body 110 is used to be electrically connected to electrical components to control the switch.

[0033] Specifically, the switch body 110 can be electrically connected to the heating plate through wires to achieve temperature control of the heating plate.

[0034] In terms of the construction of the snap-fit ​​structure, the snap-fit ​​structure includes two relatively arranged limit buckles 120 and a positioning portion 290 arranged between the two limit buckles 120. The switch body 110 is provided with a mounting portion 130. The two limit buckles 120 can be elastically deformed to accommodate the mounting portion 130. The positioning portion 290 is used to position the mounting portion 130. The limit buckles 120 and the positioning portion 290 are matched and snap-fitted to fix the mounting portion 130.

[0035] Therefore, the mounting portion 130 of the switch body 110 is pressed between the two limit buckles 120, the two limit buckles 120 are elastically deformed, and the mounting portion 130 of the switch body 110 is buckled and positioned on the positioning portion 290. When the limit buckle 120 and the positioning portion 290 are buckled together, the mounting portion 130 of the switch body 110 is fixed. Therefore, there is no need to install the switch body 110 by means of screws, which makes assembly more convenient and improves production efficiency.

[0036] In terms of the structure of the box body 100, the box body 100 includes a first shell 140 and a second shell 150. The snap-fit ​​structure is arranged in one of the first shell 140 and the second shell 150, and is located in a cavity formed between the first shell 140 and the second shell 150. One of the first shell 140 and the second shell 150 is provided with a snap-fit ​​portion 160, and the other of the first shell 140 and the second shell 150 is provided with a snap-fit ​​portion 170. The snap-fit ​​portion 160 and the snap-fit ​​portion 170 are snap-fitted to connect and fix the first shell 140 and the second shell 150.

[0037] Therefore, the switch body 110 is isolated from the outside by the first shell 140 and the second shell 150 to improve the safety of the switch. Moreover, the first shell 140 and the second shell 150 can be quickly installed together by snapping together the snap-fit ​​portion 160 and the snap-fit ​​portion 170. Therefore, there is no need to install the box body 100 by means of screws, which makes assembly more convenient and improves production efficiency.

[0038] In some embodiments of the present invention, the positioning portion 290 is a square groove, which is disposed on the first shell 140 . The square groove accommodates the mounting portion 130 , and the square groove is adapted to the mounting portion 130 .

[0039] Therefore, the square groove has a firm structure and can effectively limit the position of the mounting portion 130 . Moreover, the square groove has a simple structure and is not easily damaged, so that the switch body 110 is firmly mounted on the first shell 140 .

[0040] In some embodiments of the present invention, referring to Figure 2 and Figure 3The limiting buckle 120 includes an elastic plate 180 and a blocking portion 190 arranged on the elastic plate 180 . The elastic plate 180 is arranged on the first shell 140 . The blocking portion 190 is located on the side of the elastic plate 180 close to the mounting portion 130 . The blocking portion 190 is used to prevent the mounting portion 130 from separating from the positioning portion 290 .

[0041] It is understandable that the blocking portion 190 is provided with a chamfer, and when the switch body 110 is pressed into the limit buckle 120, the switch body 110 abuts against the chamfer of the blocking portion 190, which can make the installation of the switch body 110 easier.

[0042] In a further embodiment of the present invention, referring to Figure 5 The first shell 140 is provided with a through avoidance hole 200 , and the elastic plate 180 extends from the inside of the first shell 140 to the avoidance hole 200 .

[0043] Therefore, during the production process of the switch device, if the switch body 110 needs to be repaired, the elastic plate 180 can be moved at the position of the avoidance hole 200 to make the blocking part 190 leave the mounting part 130 of the switch body 110, thereby quickly removing the switch body 110 from the first shell 140, greatly reducing the difficulty of maintenance.

[0044] In a further embodiment of the present invention, referring to Figure 5 The snap-fit ​​portion 160 is an elastic hook, and a socket 210 is formed on the side of the elastic plate 180 away from the blocking portion 190. The socket 210 has an insertion cavity 220 extending from the inside of the box body 100 to the outside. The insertion cavity 220 accommodates the elastic hook. A limiting edge is provided on the edge of the insertion cavity 220. The limiting edge is the snap-fit ​​portion 170, and the elastic hook is buckled with the limiting edge.

[0045] Therefore, the socket 210 improves the elastic deformation capability of the elastic plate 180 and prevents the switch body 110 from being broken or damaged during installation.

[0046] In a further embodiment of the present invention, a heat dissipation cavity 230 for heat dissipation is formed on a side of the second shell 150 close to the first shell 140 , and the elastic hook is disposed on a side wall of the heat dissipation cavity 230 .

[0047] Therefore, the heat dissipation cavity 230 is located close to the switch body 110 , and the heat generated by the switch body 110 during the temperature adjustment process can be discharged through the heat dissipation cavity 230 .

[0048] In some specific embodiments of the present invention, refer to Figure 4 The heat dissipation cavity 230 is provided with a plurality of strip holes 240 , and the plurality of strip holes 240 are distributed side by side along the periphery of the heat dissipation cavity 230 , thereby greatly improving the heat dissipation capacity of the heat dissipation cavity 230 .

[0049] In some embodiments of the present invention, the switch body 110 is connected to an electric wire, and a wire threading hole 250 for accommodating the electric wire is provided between the first shell 140 and the second shell 150 , thereby facilitating the wire to pass through.

[0050] In some embodiments of the present invention, the first shell 140 is provided with a wiring card slot 260 for arranging electric wires, and the wiring card slot 260 is arranged in the axial direction of the wire threading hole 250 .

[0051] Therefore, the wiring card slot 260 can limit the position of the wires, and the wires are not easily dislocated when passing through the wire threading hole 250, which facilitates assembly.

[0052] In some embodiments of the present invention, the switch body 110 has a rotating shaft 270 extending outward from the inside of the box body 100 , and the rotating shaft 270 is coaxially connected to a knob 280 , so that the temperature can be adjusted by turning the knob 280 .
