Description
Technical field
The utility model relates to a kind of dust catcher with air intake filtering frame.
Background technology
Existing dust catcher, its filter are directly to insert in the fixed-grid of body, and it causes filter to be not easy to insert, and the not good leakiness ash of sealing after inserting, and the fixed-grid of body can be blocked incoming air area, influences entering of air-flow, causes pneumatic noise higher.
Summary of the invention
The utility model purpose is: a kind of dust catcher with air intake filtering frame is provided.
The technical solution of the utility model is: a kind of dust catcher with air intake filtering frame, it comprises: accommodate the end of motor, at the vacuum chamber in the place ahead, end, removably be installed in the air intake filtering frame between end and the vacuum chamber and removably be installed in filter in the air intake filtering frame, wherein said air intake filtering frame comprises substrate and cover plate that can relative substrate Unscrew, and described filter is between substrate and cover plate.
On the basis of technique scheme, further comprise attached technical scheme:
Substrate described in the utility model comprises several substrate muscle that are provided with at interval, be positioned at a through hole of lateral border setting, be positioned at the boss that the top edge of through hole is provided with.
Cover plate described in the utility model comprises the rotating shaft that is positioned at a side, cover plate muscle that several are provided with at interval, is positioned at a salient point of opposite side, and its bumps is held with boss elasticity button and cooperated.
The muscle of substrate described in the utility model is radial and concentrates to the center, and the cover plate muscle also is radial and concentrate to the center.
Substrate described in the utility model further comprises a breach, and described cover plate further comprises a lug that can be housed in the breach.
The top of filtering frame described in the utility model is provided with is convenient to the attacker that the user picks and places.
The utility model advantage is:
The utility model can be realized the well secured of filter, guarantees good sealing, is convenient to picking and placeing of user simultaneously, can reduce pneumatic noise again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is the schematic perspective view of air intake filtering frame of the present utility model under first visual angle;
Fig. 3 is the schematic perspective view of air intake filtering frame of the present utility model under second visual angle;
Wherein: 10, rearward end; 12, vacuum chamber; 20, air intake filtering frame; 22, substrate; 24, cover plate; 30, filter; 200, attacker; 220, substrate muscle; 222, through hole; 224, boss; 226, breach; 240, rotating shaft; 242, cover plate muscle; 244, salient point; 246, lug.
The specific embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of specific embodiment with dust catcher of air intake filtering frame, and it comprises the end 10 of accommodating motor (not shown), at the vacuum chamber 12 in 10 the place aheads, end, removably be installed in the air intake filtering frame 20 between end 10 and the vacuum chamber 12 and removably be installed in filter 30 in the air intake filtering frame 20.Wherein the top of air intake filtering frame 20 is provided with an attacker 200, picks and places to make things convenient for the user.
Air intake filtering frame 20 comprises substrate 22 and cover plate 24 that can relative substrate 22 Unscrews, and wherein filter 30 is placed between substrate 22 and the cover plate 24.Substrate 22 comprise several be provided with at interval and be substrate muscle 220 radial and that concentrate to the center, a pair of through hole 222 that is provided with at lateral border, the boss 224 and the breach between through hole 222 226 that are provided with at the top edge of respective through hole 222.Cover plate 24 comprises the rotating shaft 240 that is positioned at a side, several are provided with at interval and it is radial to be and concentrate to the center cover plate muscle 242, a pair of salient point 244 that is positioned at opposite side and a lug 246.Its bumps 244 can cooperate with corresponding boss 224 strains, and lug 246 is housed in the breach 226.
When need are changed filter 30, the user takes out air intake filtering frames 20 with the attacker 200 that finger passes through the top, catch the lug 246 phase countershafts 240 of cover plate 24 to be rotated counterclockwise then, because salient point 244 is originally at through hole 222 places, upwards run into boss 224 then and be out of shape, break away from fixing and opening of boss 224 thus, take out filter 30 this moment, again the filter 30 that renews again, then catch the lug 246 phase countershafts 240 of cover plate 24 to turn clockwise, salient point 244 runs into boss 224 downwards and is out of shape, and the below of boss 224 is a through hole 222, salient point 244 enters into through hole 222 places, is moved up by boss 224 restrictions thus.
During use, at a high speed rotation and produce vacuum of the vacuum motor of dust catcher (not shown) contains thin dirt air-flow and enters in the filter 30 from the gap location of substrate muscle 220, and then enters in the motor by the gap location of cover plate muscle 242.Simultaneously because substrate muscle 220 and cover plate muscle 242 all is radial and concentrate to the center, and both shapes are identical, and steering current enters and outflow filter sheet 30 more swimmingly thus, reduces pneumatic noise.
The utility model can be realized the well secured of filter, guarantees good sealing, is convenient to picking and placeing of user simultaneously, can reduce pneumatic noise again.
Certainly the foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
