[0056] like Fig.12 As shown, after the temperature control switch 300 is installed in the installation portion 211 of the bracket body 210, the bracket body 210 is installed on the first bracket 400 in the opposite direction of the first direction X. Specifically, the first bracket 400 includes a second limiting portion 410 and at least one first buckle 420. The second limiting portion 410 and the at least one first buckle 420 are located on one side of the first bracket 400 in the first direction X. The second limiting portion 410 and the at least one first buckle 420 are close to the second end of the first bracket 400 in the second direction Y. In this embodiment, taking one first buckle 420 as an example, the first buckle 420 is closer to the second end of the first bracket 400 in the second direction Y than the second limiting portion 410. The bracket body 210 has a first end and a second end in the length direction. The length direction of the bracket body 210 is parallel to the second direction Y. When the bracket body 210 is installed on the first bracket 400 in the opposite direction of the first direction X, the first end of the bracket body 210 in the opposite direction of the second direction Y is inserted into the second limiting portion 410 of the first bracket 400. The second limiting portion 410 is used to limit the first end of the bracket body 210 in the first direction X. The second end of the bracket body 210 in the second direction Y is pressed into the first buckle 420 on the first bracket 400. The first buckle 420 is used to limit the second end of the bracket body 210 in the first direction X, thereby installing the bracket body 210 on the first bracket 400. The above structure is conducive to a more stable installation of the bracket body 210 on the first bracket 400, and also facilitates assembly by production line employees.

[0057] like Fig.11As shown, the first bracket 400 is provided with at least one first through hole portion 430, and the first through hole portion 430 penetrates the first bracket 400 in the first direction X, so that part of the heating element 500 is exposed through the first through hole portion 430, and the first through hole portion 430 is provided with two first partition portions 440, and the two first partition portions 440 are arranged in sequence along the length direction of the first bracket 400, and the first partition portion 440 is a rib, and the thickness of the rib in the first direction X is between 0.2-2mm.

When the first bracket 400 is in place, the abutting portion 320 of the temperature control switch 300 faces the heating element 500 through the first through hole portion 430 in the opposite direction of the first direction X. At this time, the abutting portion 320 of the temperature control switch 300 and the heating element 500 are separated by the first separating portion 440 of the first through hole portion 430 in the opposite direction of the first direction X, so that the abutting portion 320 of the temperature control switch 300 cannot directly abut against the heating element 500 in the opposite direction of the first direction X, so that the temperature control switch 300 does not directly contact the heating element 500, avoiding the problem that the temperature control switch 300 directly contacts the heating element 500 and absorbs part of the heat of the heating element 500, resulting in low local temperature of the heating element 500, thereby causing the image to be not fixed firmly, and the effect of monitoring the ambient air temperature can be achieved through the first through hole portion 430. In an optional implementation, the first through hole portion 430 may not be provided with the first separating portion 440 , but the abutting portion 320 of the temperature control switch 300 directly contacts the heating element 500 through the first through hole portion 430 .

[0058] like Fig.13 As shown, the second bracket 600 is used to install at least one heat-sensitive component 700, which is a thermistor. The length direction, width direction and thickness direction of the second bracket 600 are respectively parallel to the length direction, width direction and thickness direction of the first bracket 400. In this embodiment, taking two heat-sensitive components 700 as an example, the two heat-sensitive components 700 are installed on the second bracket 600 along the first direction X. After being installed on the second bracket 600, the two heat-sensitive components 700 are distributed in sequence along the second direction Y. The way in which the two heat-sensitive components 700 are installed on the second bracket 600 can refer to the way in which the temperature control switch 300 is installed on the bracket body 210, so it is not repeated here.

[0059] like Fig.13As shown, after the heat-sensitive element 700 is installed on the second bracket 600, the second bracket 600 is installed on the first bracket 400 in the opposite direction of the first direction X, so that the heat-sensitive element 700 contacts the heating element 500. Specifically, the first bracket 400 also includes a third limiting portion 450 and at least one second buckle 460. The third limiting portion 450 and the at least one second buckle 460 are located on one side of the first bracket 400 in the first direction X. The third limiting portion 450 and the at least one second buckle 460 are close to the first end of the first bracket 400 in the opposite direction of the second direction Y. In this embodiment, taking two second buckles 460 as an example, the two second buckles 460 and the third limiting portion 450 are distributed in sequence on the first bracket 400 along the second direction Y. The second bracket 600 has a first end, a connecting portion, and a second end in the length direction. The connecting portion of the second bracket 600 is used to connect the first end of the second bracket 600 and the second end of the second bracket 600. The length of the second bracket 600 The degree direction is parallel to the second direction Y. When the second bracket 600 is installed on the first bracket 400 in the opposite direction of the first direction X, the second end of the second bracket 600 in the second direction Y is clamped into the third limiting portion 450 of the first bracket 400. The third limiting portion 450 is used to limit the second end of the second bracket 600 in the first direction X. The connecting portion of the second bracket 600 is pressed into one of the second buckles 460 on the first bracket 400. The second buckle 460 is used to limit the connecting portion of the second bracket 600 in the first direction X. The first end of the second bracket 600 in the opposite direction of the second direction Y is pressed into another second buckle 460 on the first bracket 400. The second buckle 460 is used to limit the first end of the second bracket 600 in the first direction X, thereby installing the second bracket 600 on the first bracket 400. The above structure is conducive to more stable installation of the second bracket 600 on the first bracket 400, and also facilitates assembly by production line employees. In an optional embodiment, the second clip 460 for limiting the connecting portion of the second bracket 600 in the first direction X may be located at the connection between the connecting portion of the second bracket 600 and the first end of the second bracket 600. Therefore, the second clip 460 may also limit the first end of the second bracket 600 in the first direction X. Similarly, the second clip 460 may also be located at the connection between the connecting portion of the second bracket 600 and the second end of the second bracket 600, thereby limiting the second end of the second bracket 600.

[0060] like Fig.13As shown, the first bracket 400 is provided with at least one second through hole portion 470, and the second through hole portion 470 penetrates the first bracket 400 in the first direction X, so that part of the heating element 500 is exposed through the second through hole portion 470. In this embodiment, taking two heat-sensitive elements 700 as an example, the first bracket 400 is correspondingly provided with two second through hole portions 470, and the two second through hole portions 470 are sequentially arranged on the first bracket 400 along the length direction of the first bracket 400. When the second bracket 600 is installed on the first bracket 400 in the opposite direction of the first direction X, the heat-sensitive element 700 abuts against the heating element 500 through the second through hole portion 470 in the opposite direction of the first direction X, and the heat-sensitive element 700 completes monitoring of the temperature of the heating element 500 and the temperature around the heating element 500 through the second through hole portion 470. In an optional embodiment, the second through hole portion 470 can be provided with a partition portion like the first through hole portion 430, and the partition portion is used to separate the heat-sensitive element 700 and the heating element 500 in the opposite direction of the first direction X, so that the heat-sensitive element 700 cannot directly abut against the heating element 500 in the opposite direction of the first direction X, so that the heat-sensitive element 700 does not directly contact the heating element 500, which avoids the problem that the heat-sensitive element 700 absorbs part of the heat of the heating element 500 when directly contacting the heating element 500, resulting in a local low temperature of the heating element 500, thereby causing the image to be fixed loosely, and the effect of monitoring the temperature of the heating element 500 can be completed through the second through hole portion 470.

[0061] like Fig.13 As shown, the second bracket 600 also includes a spring portion 610. In the present embodiment, taking two heat-sensitive components 700 as an example, correspondingly, two spring portions 610 are provided. The two spring portions 610 are sequentially arranged on the second bracket 600 along the length direction of the second bracket 600. The spring portion 610 is used to apply force to the heat-sensitive component 700 in the opposite direction of the first direction X to press the heat-sensitive component 700 toward the heating component 500. At this time, the two second buckles 460 on the first bracket 400 can make the installation of the second bracket 600 more secure, thereby solving the problem of the second bracket 600 being arched due to the elastic force of the spring portion 610.

[0062] In this embodiment, after the temperature control switch 300 is installed on the bracket body 210 along the first direction X, the temperature control switch 300 is limited in the opposite direction of the first direction X by using the first claw 212a and the second claw 212b on the bracket body 210, so that the temperature control switch 300 is fixed at the effective detection position on the ceramic plate bracket (i.e., the first bracket 400), thereby improving the response accuracy of the temperature control switch 300.

[0063] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
