Dismounting is connected, and lower cover is set in outside filter core and is removably fixed with the second connector, only need to be by under when needing replacing filter core
Lid is unloaded from the second connector, old filter core is unloaded from the first connector, so that it may be reinstalled new filter core, whole mistake
Journey is convenient, fast, and filtration channel is equipped between filter core and lower cover, when gas is entered in lower cover from air inlet, gas
Cognition is spread apart in filtration channel to be come, and then adds the contact area of filtering gas and filter core, is accelerated the rate of filtration, is carried
High filter efficiency.
Further, first connector includes the connected unit extended inwardly to form by the upper cover body inner wall and by even
Connect platform to stretch out the connection edge to be formed, the connection edge is equipped with external screw thread, and the filter core is equipped with internal thread；Filter core by with
Connection edge, which is spirally connected, to be realized and is removably fixed with first connector, is convenient for changing filter core.
Further, second connector stretches out the lug to be formed for the upper cover body bottom, on the lug
Equipped with internal thread, the lower cover is equipped with external screw thread；Lower cover is connected by the detachable of be spirally connected realization and the upper cover body with lug
Connect, and when lower cover and the second connector are tightly engaged by screw thread, the end face of lower cover can be with the connected unit bottom in upper cover body
Face is in close contact, and adds the air-tightness of whole filter.
Further, the filtration channel width is 0.5-1cm；Filtration channel is set wider, is further increased
The contact area of air filtration body and filter core, lifts filter efficiency.
Preferably, it is equipped with activated carbon filter layer in the upper cover body；Peculiar smell in activated carbon energy adsorption filtration gas, favorably
In improvement vacuum pump surrounding air environment.
Further, the lower cover end face is equipped with annular seal pad；When lower cover and the second connector are closely nibbled
During conjunction, lower cover end face annular seal pad can be in close contact with the connected unit bottom surface in upper cover body, improve whole filter
Interior air-tightness.
In conclusion the utility model being removably fixed with by filter core and the first connector, is convenient for changing filter core, lower cover
Filtration channel is provided between body and filter core, accelerates the rate of filtration, lifts filtering rate.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model.
Embodiment
It is real below in conjunction with the utility model in order to make those skilled in the art be better understood from the utility model
The attached drawing in example is applied, clear, complete description is carried out to the technical scheme in the embodiment of the utility model.
As shown in Figure 1, a kind of vacuum Filter for pump, including upper cover body 1 and lower cover 2, the lower cover 2 are equipped with air inlet
Mouth 21, the upper cover body 1 is equipped with gas outlet 11, and air inlet 21 is arranged on 2 bottom of lower cover, and gas outlet 11 is arranged on upper cover body
Internal thread is designed with top, air inlet 21 and gas outlet 11, one can be screwed onto respectively and equipped with externally threaded pump housing snorkel
Rise, and then conveniently disassemble filter from pump housing snorkel.The upper cover body 1 is equipped with the first connector and second and connects
Fitting, is removably connected with filter core 3 on first connector, and then is convenient for changing filter core 3, and the lower cover 2 is sheathed on filter
Core 3 is outer and is detachably connected with second connector, and filtration channel 4 is equipped between the lower cover 2 and filter core 3, and filtering is logical
4 width of road is 0.5-1cm, and when gas is out of air inlet 21 entrance lower cover 2, gas can be spread apart in filtration channel to be come, into
And the contact area of gas and filter core is added, the rate of filtration is accelerated, improves filter efficiency, specifically, filtration channel 4 is wide
Spend for 1cm, further speeded up the rate of filtration.
Specifically, first connector include the connected unit 12 that is extended inwardly to form by 1 inner wall of upper cover body and by
Connected unit 12 stretches out the connection edge 13 to be formed, and the connection edge 13 is equipped with external screw thread, and the filter core 3 is equipped with internal thread,
Filter core 3 is realized and is removably fixed with the first connector by being spirally connected with being connected edge 13, is convenient for changing filter core 3, and the connection
Edge 13 is cylindrical shape, and the filter core 3 is also cylindrical shape, further increases the contact area with filtering gas, improves filtering effect
Rate.
Further, second connector stretches out the lug 14 to be formed for 1 bottom of upper cover body, the lug
14 are equipped with internal thread, and the lower cover 2 is equipped with external screw thread, when lower cover 2 is tightly engaged with lug 14, the end of lower cover 2
Face can be in close contact with the bottom surface of connected unit 12, and then add the air-tightness for entirely crossing air filtration, as preference, in lower cover
One annular seal pad 22 is set on 2 end faces, and gasket 22 further increases the airtight of lower cover 2 and 1 junction of upper cover body
Property.
As preference, an activated carbon filter layer 15 is set in the upper cover body, in activated carbon energy adsorption filtration gas
Peculiar smell, be conducive to improve vacuum pump surrounding environment.
Specifically, when the gas in the pump housing enters in filter from air inlet 21, gas can be in lower cover 2 and filter core 3
Between filtration channel 4 in spread apart come, then by filter core 3, filter core 3 can filter out gelatinization oil product and dust in gas
, then the gas after the filtering of filter core 3 is entered in activated carbon filter layer 15, in the energy adsorbed gas of activated carbon filter layer 15
Peculiar smell, finally discharges the gas after filtering through gas outlet 11.In the filter core 3 because adsorbing too many gelatinization oil product and dust particles and
When cannot play filter effect, vacuum Filter for pump can be unloaded down from pump housing snorkel, rotation upper-lower casing is allowed to point
From rear, it is possible to old filter core is rotated from flange, reinstalls a new filter core, whole replacement process is simply, just
It is prompt.
