[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, in the embodiment of the utility model: it includes a recycling box 1, an air outlet 2 and an air inlet 3 installed on the outer wall of the recycling box 1; the recycling box 1 is used for air intake and exhaust through the air outlet 2 and the air inlet 3 during use; the above are all prior arts, and this application does not protect them here, so no further elaboration is made.

[0020] like Figure 1 and Figure 2 As shown, the recycling box 1 is connected with a filter screen 4 through an installation mechanism, and the installation mechanism includes a connecting plate 5 connecting two groups of filter screens 4, and a plug plate 6 is installed on the side wall of the connecting plate 5, and the plug plate 6 is inserted in the recycling box 1, and a first slot 7 is opened on the side wall of the other connecting plate 5, and a limiting plate 10 is connected to the first slot 7 through a first elastic member 9, and the limiting plate 10 is inserted in the plug-in slot 13, and the plug-in slot 13 is opened in the recycling box 1; the limiting plate 10 connected to one side of the first elastic member 9 is first plugged into the plug-in slot 13 At this time, the limiting plate 10 is squeezed, and after the limiting plate 10 is stored in the first slot 7 under the action of the elastic potential energy of the first elastic member 9, space can be reserved for the plug-in plate 6 to be plugged into the inner wall of the recycling box 1. At this time, the plug-in plate 6 is aligned with the limiting slot opened on the inner wall of the recycling box 1, and the pressure of the elastic squeezing is released, so that the plug-in plate 6 and the inner wall of the recycling box 1 are docked and plugged under the cooperation of the elastic reaction force of the first elastic member 9, and the installation of the filter screen 4 on the inner side of the recycling box 1 can be completed.

[0021] It should be noted that if Figure 2 As shown, in this embodiment, a spring is used as an elastic component to force the limiting plate 10 to move inside the first slot 7, but in some other embodiments, other elastic components such as a spring leaf, an elastic paddle, etc. can also be used.

[0022] like Figure 2 As shown, the installation mechanism also includes a first slide rail 12 provided in the first slot 7, and a first slider 11 slides in the first slide rail 12, and the first slider 11 is installed at the upper and lower ends of the inner side of the limiting plate 10; when the first slider 11 and the first slide rail 12 are used in sliding cooperation, the stability of the limiting plate 10 moving inside the first slot 7 is improved.

[0023] like Figure 1 and Figure 2 As shown, the front cross-section of the connecting plate 5 is set to a "right-angled trapezoid" shape; the side wall of the connecting plate 5 can be easily docked with the recycling box 1, and the staff can easily pick up the filter screen 4 with the help of the special shape of the connecting plate 5.

[0024] like Figure 2 and Figure 3As shown, the outer wall of the filter 4 is symmetrically provided with a second slot 8, and the second slot 8 is connected with a mounting frame 15 through a second elastic member 18, the outer side walls of the mounting frame 15 are all rollingly embedded with balls 14, and the outer side walls of the balls 14 are all rollingly abutted against the inner wall of the recycling box 1, the inner walls of the second slot 8 are symmetrically provided with second slide rails 17, and the second slide rails 17 are all slidably connected with second sliders 16, and the second sliders 16 are all fixedly installed on the outer side walls of the mounting frame 15; when the filter 4 is installed with the recycling box 1, due to the coordinated use of the plug plate 6 and the limit plate 10, a space gap will be formed with the inner wall of the recycling box 1. At this time, with the elastic potential energy of the second elastic member 18, the balls 14 and the mounting frame 15 are abutted against the inner wall of the recycling box 1 during normal use, so as to ensure the stable efficiency of the filter 4 installed on the inner side of the recycling box 1. When the filter 4 is disassembled, the balls 14 and the mounting frame 15 will be compressed into the second slot 8 under the coordinated use of the elastic potential energy of the second elastic member 18.
