Abstract
The invention relates to a filtering box of a dust collector, comprising a box body, an upper cover provided with an air inlet and a filtering sponge arranged in the box body and further comprising a circular baffle, wherein the circular baffle is arranged above the filtering sponge in the box body below the air inlet; one side of the circular baffle, facing to the air inlet, is a convex surface; and the circular baffle is connected on the air inlet by a plurality of hanging springs. In the filtering box of the dust collector, the circular baffle is arranged at the part blocked by dust, namely below the air inlet so as to guide the gas flowing from the air inlet, the dust particles in the gas are dispersed on the area of the whole sponge instead of gathering at the circular area of the filtering sponge below the air inlet to cause blocking. Therefore, the dust does not block the air inlet of the filtering box, so the collecting capability of the dust collector is guaranteed.
Description
Technical field
The invention belongs to the dust catcher field, particularly relate to a kind of circular baffle plate that below air inlet, is provided with and come water conservancy diversion gas, make dust not concentrate on the filtration sponge place of air inlet below circular area, can not stop up air inlet, guarantee the dust catcher filter cartridge of dust catcher suction.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.In general, dust catcher mainly comprises aspirator and suction line, with motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, suction line comprises suction nozzle and air intake duct, and the air entry of the oriented under shed of suction nozzle and the telescoping tube by air intake duct and flexible pipe communicate with air inlet in the body.In dust catcher when running,, the impeller of motor drives blower fan rotates at a high speed, and the air of dust catcher inside is discharged, and forms instantaneous vacuum in the inside of dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the suction nozzle dust sucks in the cyclone separator of body together with air by air entry, the air that contains dust in cyclone separator after separating, enter from exhaust outlet again and carry out secondary filter in the filter cartridge, gas after the filtration enters exhaust flow path, is discharged to the outside of dust catcher.Like this, just reach the effect of dust out, clean floor.
The filter cartridge of prior art dust catcher as shown in Figure 1, filter cartridge is made of box body 3, the loam cake 1 that is provided with air inlet 5, the filtration sponge 9 that is contained in the box body.
There are the following problems for the filter cartridge of prior art dust catcher:
Existing dust catcher (model Nile) is after putting goods on the market, in the investigation to client, reflect dust and often be blocked in the problem that causes body suction to descend rapidly in the filter cartridge, dust is blocked in the sponge place of the circular area corresponding with the filter cartridge air inlet fully, cause air quantity near zero after the obstruction, this moment, dust catcher can completely lose the effect of dust suction, brought very big inconvenience to client, caused the very big suggestion of client.
Summary of the invention
The present invention provides a kind of circular baffle plate that is provided with below air inlet to come water conservancy diversion gas for solving the technical problem that exists in the known technology, make dust not concentrate on the filtration sponge place of air inlet below circular area, can not stop up air inlet, guarantee the dust catcher filter cartridge of dust catcher suction.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Dust catcher filter cartridge of the present invention, comprise: box body, be provided with air inlet loam cake, be contained in the filtration sponge in the box body, also comprise: a circular baffle plate that is provided with above the filtration sponge under air inlet in the square box, circular baffle plate simultaneously is a convex surface towards air inlet, and circular baffle plate is connected on the air inlet by a plurality of hanger springs.
Described hanger spring is connected on the air inlet by reclinate spring reference column.
Described spring reference column and air inlet are integrally formed.
The quantity of described hanger spring is at least 2.
Described circular baffle plate is connected on the box bottom plate by support spring.
Described support spring one end is connected below the circular baffle plate, and the other end is connected on the box bottom plate by the spring mounting hole that filters on the sponge.
Advantage and good effect that the present invention has are:
Dust catcher filter cartridge of the present invention, below being air inlet, the position that dust stops up is provided with the gas that circular baffle plate comes water conservancy diversion to be flowed into by air inlet, dust granule in the gas is dispersed on the area of whole filtration sponge, does not result in blockage and be not concentrated in the border circular areas of air inlet below filtration sponge.
In addition, hanger spring and support spring can play the effect of supporting circular baffle plate and clapping dirt by vibrations, and above-mentioned effect makes dust be not plugged in the air inlet of filter cartridge, has guaranteed dust catcher suction.

The specific embodiment
It is following that the present invention will be described with reference to drawings and Examples.
Parts same as the prior art have used identical symbol in the accompanying drawing of the present invention.
The 1st embodiment of the filter cartridge of dust catcher of the present invention, to shown in Figure 6, Fig. 2 is a dust catcher filter cartridge stereogram of the present invention as Fig. 2; Fig. 3 is the air inlet position enlarged drawing of Fig. 2; Fig. 4 is a dust catcher filter cartridge vertical view of the present invention; The A-A cutaway view of Fig. 4 of Fig. 5; Fig. 6 is the air inlet position enlarged drawing of Fig. 5.
The filter cartridge of dust catcher of the present invention, by box body 3, be provided with air inlet 5 loam cake 1, be contained in filtration sponge 9 in the box body, be arranged on a circular baffle plate 4 of filtering the sponge top and form with a plurality of hanger springs 2 that are connected circular baffle plate.
Circular baffle plate is arranged on the interior filtration sponge corresponding with air inlet of square box top under the air inlet.
