Example
[0046] Reference Figure 1 and Figure 3~Figure 7 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.
[0047] Specifically, the fixing member 203 includes a supporting frame 203a and a sliding rod 203b. The supporting frame 203a is fixed to the inner wall of the fixing shell 101, and the sliding rod 203b slides in the supporting frame 203a.

[0049] Specifically, the fixing member 203 further includes a pressing plate 203c and a second spring 203d. The pressing plate 203c is fixed to the end of the slide bar 203b, and two ends of the second spring 203d are respectively fixed to the inner wall of the pressing plate 203c and one side of the support frame 203a.
[0050] The second spring 203d is in a stretched state, and the extrusion disk 203c is used to squeeze the connecting sleeve 201d so that the connecting sleeve 201d and the filter screen 103a are tightly connected.
[0051] Specifically, the fixing member 203 further includes a rotating ring 203e and a driving block 203f. The rotating ring 203e is rotatably connected to the fixed shell 101, and the driving block 203f is fixed to one side of the rotating ring 203e.
[0052] By rotating the rotating ring 203e, the rotating ring 203e can drive the driving block 203f to move, so that the driving block 203f drives the sliding rod 203b to move, so that the sliding rod 203b drives the extrusion disk 203c to squeeze the connecting sleeve 201d, so that the connecting sleeve 201d and the filter screen 103a are tightly connected.
[0053] Specifically, the fixing member 203 also includes an insert 203g, a sleeve 203h, a third spring 203i, a rotating shaft 203j, a gear 203k and a driving wheel 203l. The insert 203g is fixed to one side of the rotating ring 203e, the sleeve 203h slides in the sealing cover 201b, the two ends of the third spring 203i are respectively fixed to one side of the sleeve 203h and the top of the sealing cover 201b, the rotating shaft 203j is rotatably connected in the sleeve 203h, the gear 203k is fixed to the end of the rotating shaft 203j, and the driving wheel 203l is fixed to the other end of the rotating shaft 203j.
[0054] The insert strip 203g is inserted into the sealing cover 201b to limit the sealing cover 201b. The sliding sleeve 203h is used to support the rotating shaft 203j. The third spring 203i is in a normal state. At this time, the gear 203k and the tooth groove opened on one side of the rotating ring 203e are engaged. By rotating the driving wheel 203l, the gear 203k can be driven to rotate, so that the gear 203k drives the rotating ring 203e to rotate. When the rotating ring 203e rotates, it can drive The driving block 203f moves, so that the driving block 203f drives the sliding rod 203b to move, so that the sliding rod 203b drives the extrusion disk 203c to squeeze the connecting sleeve 201d, so that the connecting sleeve 201d and the filter screen 103a are tightly connected. At the same time, when the rotating ring 203e rotates, it can drive the insertion strip 203g to be inserted into the sealing cover 201b, limit the sealing cover 201b, and fix the sealing cover 201b on the fixed shell 101.
[0055] When the filter 103a needs to be cleaned or replaced during use, the driving wheel 2031 can be rotated to drive the gear 203k to rotate, so that the gear 203k drives the rotating ring 203e to rotate. When the rotating ring 203e rotates, the driving block 203f can be driven to move, so that the driving block 203f is away from the sliding rod 203b. At this time, under the action of the reset pulling force of the second spring 203d, the squeezing plate 203c can be moved away from the connecting sleeve 201d, thereby releasing the squeezing of the connecting sleeve 201d on the filter 103a. When the rotating ring 203e rotates, the rotating ring 203e will drive the insert 203g to move out of the sealing cover 201b, thereby releasing the limit on the sealing cover 201b. At this time, pulling the driving wheel 203l can drive the sliding sleeve 203h to move, so that the gear 203k is away from the rotating ring 203e. At this time, the sealing cover 201b can be opened, and under the action of the reset elastic force of the first spring 202b, the support plate 202a can pop a part of the filter screen 103a out of the fixed shell 101, thereby facilitating the replacement of the filter screen 103a.
[0056] When the filter screen 103a is fixed, the new filter screen 103a can be plugged into one side of the connecting sleeve 201d and located on the top of the support plate 202a. At this time, the sealing cover 201b can be covered, and the sealing cover 201b will squeeze the filter screen 103a, so that the filter screen 103a moves to the working position. While covering the sealing cover 201b, the driving wheel 203l can be rotated to rotate the gear 203k, so that the gear 203k can mesh with the tooth groove on one side of the rotating ring 203e, thereby driving the rotating ring 203e to rotate. The movable ring 203e rotates, thereby driving the driving block 203f to move, so that the driving block 203f drives the sliding rod 203b to move, so that the sliding rod 203b drives the extrusion disk 203c to squeeze the connecting sleeve 201d, so that the connecting sleeve 201d and the filter screen 103a are tightly connected. At the same time, when the rotating ring 203e rotates, it can drive the insertion strip 203g to be inserted into the sealing cover 201b, limit the sealing cover 201b, and fix the sealing cover 201b on the fixed shell 101.
