In the optional scheme of the embodiment, multiple air inlet holes 314 are offered in the cover wall of air intake cover 301.

In the optional scheme of the embodiment, after filter core is installed on air intake cover 301, the opening of the close air intake cover 301 of filter core End cover of filter element 305 be inserted into the ring of first end cover 302, and after first end cover 302 is connected with second end cover 303, the Sealing ring 307 on two end caps 303 is convenient for the capping of the end cover of filter element 305 of the opening of the close air intake cover 301 of filter core to fit, The limit of the filter core in air intake cover 301 is fixed to just realize, and sealing ring 307 and gasket 308 have elasticity can Enhancing leakproofness can reduce filter in the vibration of operating simultaneously.

The filter that the embodiment provides, when in use, after second end cover 303 is connect with the casing snap-in of host, the After one end cap 302 is connected together with air intake cover 301, by connecting the rotation between first end cover 302 and second end cover 303, Realize the separation between air intake cover 301 and the casing of host；Under the action of the wind wheel of host, outside air is from air intake cover 301 Air inlet hole 314 enter in air intake cover 301, enter master through HEPA filter screen 304, then through first end cover 302 and second end cover 303 The inside of machine, finally, from the exhaust vent discharge on host.

It is recessed that the engaging that multiple engaging boss 311 in second end cover 303 match is provided in the embodiment, on casing Slot 312 can realize that second end cover 303 fastens with the casing of host in this way and connect.Casing includes first half-shell 107 and Two half-shells 108, first half-shell 107 are connected together with the second half-shell 108.

In conclusion the motor for double-ended drive in the clarifier can simplify structure by the way that symmetrical wind wheel is arranged；Improve operating Stability；Simplifying structure reduces cost.Symmetrical filter is set, ease for use and serious forgiveness can be promoted；It is difficult to reduce assembling product Degree；Reducing number of molds reduces die cost.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.
