Both ends of each sensor strip 2 pass through the filter holder 1 and are placed in the non-loading zone 10, respectively. The sensor metal strip 2 includes a bent end 21 and a terminal end 22, and the ends of the two sides of the sensor metal strip 2 are respectively bent to form a bend for fixing the sensor metal strip 2 on the filter holder 1. Folded end 21.

In an embodiment, the bent end 21 is formed by bending the end of the first side of the sensor metal strip 2, and the terminal 22 is disposed on the end of the second side of the sensor metal strip 2. .

The body of the sensor strip 2 is placed in the load zone 20, and the profiled projections on the body of the sensor strip 2 are load contact faces.

The sensor metal strip 2 is fixed on the filter holder 1 through the bent end 21, which is convenient to install and disassemble, saves assembly time, and has simple processing and convenient processing. The sensor metal strip 2 is electrically connected to the controller through the terminal 22.

In an embodiment, the two sensor metal strips 2 comprise a first sensor metal strip and a second sensor metal strip, and the two sensor metal strips 2 may be the end of the first side of one of the sensor metal strips 2 and the sensor The ends of the second side of the metal strip 2 are respectively disposed in the isolation cavity 3; or the end of the first side of the first sensor metal strip is placed in the isolation cavity 3, and the second side of the second sensor metal strip The ends are placed in the isolation chamber 3; it is also possible that three or four of the ends of the two sensor strips 2 are placed in the isolation chamber 3.

In this embodiment, as shown in FIG. 2, the end of the first side of the first sensor metal strip and the end of the second side of the second sensor metal strip are respectively placed in the isolation cavity 3, the isolation cavity The body 3 is provided with two, including a first isolation cavity 31 and a second isolation cavity 32. Both of the isolation cavity 3 are fixed on the filter holder 1 and placed on the side of the non-load area 10, The end of the first side of one sensor strip is placed in the first isolation cavity 31 and the end of the second side of the second sensor strip is placed in the second isolation cavity 32.

In an embodiment, two of the sensor strips 2 are spaced apart from each other, and the two sensor strips 2 are parallel to each other, and the isolating cavity 3 isolates the ends of the two sensor strips 2 on the same side, effectively Preventing the foreign matter entering the non-loaded area during the operation of the dryer from contacting the ends of the two sensor strips 2 on the same side, thereby generating an interference signal and causing problems affecting the normal detection of the humidity sensor.
