Description

Air inlet grille of air purifier

Technical Field

The utility model relates to an air purifier technical field specifically is an air purifier's air inlet grid.

Background

Along with the improvement of people's standard of living, the user also is higher and higher to the requirement of quality of life, and the air pollution problem has more and more obtained people's attention at present, and some families have also been equipped with air purifier, when severe haze weather appears, can improve the quality of indoor air.

Air purifier on the existing market, its air inlet department is provided with air-inlet grille, separates into the grid hole of a plurality of equidistance through air-inlet grille's grid board with the air intake, and the grid hole generally is rectangular hole or square hole. When the air current gets into air purifier inside through the air intake, the air current also can send into the clarifier with great foreign matter inside from the grid hole of rectangle or the grid hole of square through, and after long-time the use, cause the inside work efficiency and the life greatly reduced of clarifier easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an air purifier's air-inlet grille to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an air inlet grille of air purifier, includes the grid board, a plurality of radius homogeneous change and the blade that is annular structure are seted up at the positive middle part of grid board, the clearance between the blade constitutes the grid hole that the width is the same, the blade is fixed through a plurality of bracing pieces, the back of grid board is equipped with annular structure's the cover body, the inboard of the cover body is equipped with annular structure's baffle, spacing ring and filter screen in proper order, the baffle sets up with the filter screen interval, and the filter screen is located the one side that the grid board was kept away from to the baffle, the cover body outside just corresponds and locates to be equipped with a plurality of row cinder notches between baffle and the filter screen, arrange the cinder notch and cover internal.

Furthermore, the end portion of the cover body far away from the grating plate is clamped with a fixing ring with a U-shaped cross section, and the filter screen is fixed in the cover body through a limiting ring and the fixing ring.

Further, the width of the grid holes is equal to the projection width of the blades in the direction vertical to the grid plate.

Further, the blades are all arranged in an inclined mode.

Further, one end of the blade is flush with the front face of the grid plate.

Furthermore, the slag discharge port is communicated with an external filter bag.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, with the blade annular setting, constitute the grid hole of loop configuration between the blade, when avoiding the air current to get into air purifier inside from the grid hole, the air current evenly receives blockking of blade, and can not lead to the speed of air current to change sharply, so the energy loss and the flow resistance of air current are all less, and consequently the air inlet speed of air current is little, is difficult for producing great noise.

In addition, because the filter screen has certain hindrance effect to the air current velocity of flow that passes through, when the baffle exists, obstructed air current can remove to the region between filter screen and the baffle to collide with the air current that passes through the grid hole at a high speed, form the vortex, therefore the dust foreign matter etc. that is brought in by the air current is difficult for attaching to on the filter screen under the effect of vortex, even if long-time the use also can not lead to the fact the jam to the filter screen, the vortex can be through row's cinder notch drainage pressure simultaneously, and send into in the filter bag of outside with dust foreign matter etc. and accomplish the collection of dust, realize self-cleaning function.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the technical solution of the present invention is realized as follows:

the utility model provides an air inlet grille of air purifier, including grid board 1, a plurality of radius homogeneous change and blade 2 for annular structure are seted up at the front middle part of grid board 1, clearance between blade 2 constitutes the grid hole 3 that the width is the same, blade 2 is fixed through a plurality of bracing pieces 4, the back of grid board 1 is equipped with annular structure's the cover body 5, the inboard of the cover body 5 is equipped with annular structure's baffle 6 in proper order, spacing ring 7 and filter screen 8,

baffle

6 and 8 interval settings of filter screen, and filter screen 8 is located 6 one side of keeping away from grid board 1 of baffle, the cover body 5 outside just corresponds and locates to be equipped with a plurality of row cinder notch 9 between baffle 6 and the filter screen 8, arrange cinder notch 9 and cover body 5 inside intercommunications.

With blade 2 annular setting, constitute annular structure's grid hole 3 between the blade 2, when avoiding the air current to get into air purifier inside from grid hole 3, the air current evenly receives blockking of blade 2, and can not lead to the speed of air current to change sharply, so the energy loss and the flow resistance of air current are all less, and consequently the air inlet speed of air current is little, is difficult for producing great noise.

In addition, because the filter screen 8 has certain blocking effect on the flow velocity of the passing air flow, when the partition plate 6 exists, the blocked air flow can move to the area between the filter screen 8 and the partition plate 6 and collide with the air flow passing through the grating holes 3 at high speed to form vortex, so that dust, foreign matters and the like brought by the air flow are not easily attached to the filter screen 8 under the action of the vortex, the filter screen 8 cannot be blocked even if the filter screen is used for a long time, meanwhile, the vortex can discharge pressure through the slag discharge port 9, the dust, the foreign matters and the like are sent into an external filter bag, the collection of dust is completed, and the self-cleaning function is realized.

In addition, the tip joint that the cover body 5 kept away from grid board 1 has the cross section to be the solid fixed ring 10 of U-shaped structure, and filter screen 8 is fixed in the cover body 5 inside through spacing ring 7 and solid fixed ring 10, and solid fixed ring 10 joint is at the tip of the cover body 5 to the filter screen 8 is dismantled in the change in later stage, and spacing ring 7 carries out the position from the opposite side to filter screen 8 and prescribes a limit to, makes filter screen 8's position to keep.

The width of the grid holes 3 is equal to the projection width of the blades 2 in the direction vertical to the grid plate 1, so that the integral aesthetic property is better.

The blades 2 are obliquely arranged, and the obliquely arranged blades 2 have a certain guiding function, so that the air flow can enter the blades more conveniently.

The one end of blade 2 flushes with grid plate 1's front, avoids blade 2 too outstanding, influences holistic use, also avoids blade 2 to receive the damage simultaneously.

The slag discharge port 9 is communicated with an external filter bag and is used for collecting dust and preventing dust and foreign matters from being diffused again.

The working principle is as follows:

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
