By setting the spring 13, continuous force can be provided for the adjusting rod 10, so that the adjusting rod 10 can be automatically reset.

[0021] like Figure 2 and Figure 4 As shown, a fixing frame 19 is fixedly connected inside the purifier body 1 and near the top position, and a resistance wire 20 is fixedly connected inside the fixing frame 19. By setting the resistance wire 20, the passing air can be heated to play a heating role.

[0022] like Figure 4 As shown, a support rod 21 is fixedly connected to the inner surface of the fixed frame 19, and the top of the support rod 21 is in contact with the outer surface of the resistance wire 20. By providing the support rod 21, the resistance wire 20 can be supported and the stability can be improved.

[0023] like Figure 2 As shown, a filter core 4 is inserted into the square through hole 3, and two sides of the filter core 4 are respectively slidably arranged inside two positioning plates 7, and one side of two fixing rods 12 is respectively in contact with the two sides of the filter core 4, so that the fixing rods 12 can clamp and fix the two sides of the filter core 4 to improve stability and sealing.
