Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution:
A kind of self-cleaning strainer, including by shell 11, the movable filtering device being mounted in shell 11 12 and peace
Self-cleaning device 13 in shell 11 collectively constitutes filter body 1, and self-cleaning device 13 is located at movable filtering device 12
Lower section, the upper end of shell 11 are communicated with air inlet pipe, and lower end is communicated with escape pipe, the air inlet of the lower end connection blower of escape pipe；
Movable filtering device 12 is slidably connected in the bar shaped sliding slot that 11 inner sidewall of shell symmetrically opens up by two
Sliding block 123, the disk 121 being connected between two sliding blocks 123, the filter core 122 being fixedly plugged on disk 121 composition, sliding block
123 lower end is connected with the first compressed spring 124, and the other end of the first compressed spring 124 is connected to 11 inner sidewall of shell and opens up
Bar shaped sliding slot bottom, the diameter of disk 121 is identical as the internal diameter of shell 11.
Self-cleaning device 13 be by be symmetrically connected to two brackets 132 of 11 inner sidewall of shell, be connected to two brackets 132 it
Between cleaning cylinder 131 and perforation be connected to cleaning 131 lower end of cylinder collection box 133, cleaning cylinder 131 inner sidewall lower end connection
There is annulus 134, the inner sidewall lower end of annulus 134 offers annular groove, and a circle elastic seal ring, sealing effect are covered on annular groove
Fruit is good, and the inner bottom wall of collection box 133 is connected with multiple second compressed springs, the other end of multiple second compressed springs be connected to
