Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, 2, a kind of dust-separating appliance of dust catcher, including outer barrel 1, inner cylinder 6, upper cover 2, pedestal 3
It is equipped with air inlet 11 with the upper lateral part of filter mantle 4, outer barrel 1, outer barrel 1 is arranged in the pairing by way of clamping of upper cover 2
Upper end, 3 pairing of pedestal are hinged in the lower end of outer barrel 1, one end of pedestal 3 and the side of outer barrel 1, the other end and outer barrel
The side of the clamping of 1 phase, upper cover 2 is equipped with air outlet 21, and inner cylinder 6 is co-axially located in outer barrel 1, and filter mantle 4 is cylindrical,
Filter mantle 4 is arranged in outer barrel 1, is set in 6 outside of inner cylinder, and the upper end of filter mantle 4 forms the locating cover 41 of circular ring shape,
The edge 65 that the outwardly extending bottom for filter mantle 4 is shelved, the upper end face ring of inner cylinder 6 are formed on the outer wall of inner cylinder 6
To projection there are three positioning column 64, the bottom of locating cover 41 is equipped with corresponding location hole, and filter mantle 4 passes through location hole and positioning column
64 cooperation positioning is set in outside inner cylinder 6, and the bottom of filter mantle 4 offsets with the sealing of edge 65 of inner cylinder 6, filter mantle 4
41 periphery of locating cover and the upper opening inner wall sealing of outer barrel 1 offset, and the first collection is constituted between such outer barrel 1 and filter mantle 4
Dirt room 5, inner cylinder 6 is interior to constitute the second dust storage chamber 7, and the bottom of inner cylinder 6, which forms downwards, offsets support for being isolated with pedestal 3
The support base 63 of first dust storage chamber 5, the second dust storage chamber 7, support base 63 are cylinder type, are a part of inner cylinder 6, pedestal 3
The interior seal washer 31 for being equipped with the cooperation sealing that offsets with the bottom of support base 63, setting seal washer 31 are in order to avoid the first collection
The bulky grain of dirt room 5 goes to the second dust storage chamber 7；Inner cylinder 6 is equipped with center gas outlet 61 and is connected with the air outlet 21 of upper cover 2
It is logical；In order to guide air-flow to converge toward center gas outlet 61,7 middle section position of the second dust storage chamber in inner cylinder 6 has inversed taper platform shape
Isolation position 68, make the dust for being deposited in 7 cavity of resorption of the second dust storage chamber be not easy again by air-flow carry up, improve separation effect
Fruit, isolation position 68 are removed the gas deflector cone 62 for being fixed up protrusion again by dowel 67, air-flow are made to converge toward 6 middle upper portion of inner cylinder
It is poly-, in general, crossing distribution is presented in dowel 67, thus make to be formed between adjacent dowel 67 second dust storage chamber, 7 epicoele and
The channel of cavity of resorption connection is deposited to dust intracavitary under the second dust storage chamber 7, in addition, inner cylinder 6 top circumferential direction be spaced apart set
Several tangent air inlets 66 for connection the first dust storage chamber 5 and the second dust storage chamber 7, to improve the efficiency of filtering dust, outside
Circumferential direction is equipped with the ring washer 12 of inversed taper platform shape in cylinder 1, on the downside inner wall of air inlet 11, extends still further below after sloping inwardly,
Guiding dust to precipitate downwards, prevent following dust granule from being come up by flow rotation carrying, filter mantle 4 upper end with it is upper
A filter cotton bracket 8 is additionally provided between lid 2, filter cotton bracket 8 can be washed, and the effect of filtering, filter cotton branch are further functioned as
The lid of frame 8 is located on the locating cover 41 of filter mantle 4, passes through filtering from the filtering gas that 6 center gas outlet 61 of inner cylinder is discharged in this way
It is discharged after the last filtering together of cotton bracket 8 from the air outlet 21 of upper cover 2, filter cotton bracket 8 is equipped with knob.
Working principle is such that
After opening dust collector power switch, dust catcher sucks dust and gas from the air inlet 11 of outer barrel 1, and dust and gas enters the first collection
Dirt room 5, by the guidance of ring washer 12, bulky grain dust falls into 5 bottom of the first dust storage chamber；Then filtering of the dust and gas through filter mantle 4
After mesh filtering, into the second dust storage chamber 7, dust settles in the second dust storage chamber 7 again under the action of the centrifugal force；Dust
Grain is just deposited in intracavitary under the second dust storage chamber 7, has substantially reduced the air-flow of dust concentration and has made through the gas deflector cone 62 of 6 bottom of inner cylinder
With air-flow is converged toward 6 middle upper portion of inner cylinder, the center gas outlet 61 of inner cylinder 6 is flowed through, through the further mistake of filter cotton bracket 8
Filter, finally outside the air outlet 21 of upper cover 2 discharge dust catcher.
Dust suction terminates, and closes dust collector power switch, opens pedestal 3, topples over the first dust storage chamber 5, in the second dust storage chamber 7
Dust；After a period of use, filter mantle 4 and inner cylinder 6 can also be removed, further remove and adhered on filter mantle 4 and inner cylinder 6
Dust, and filter cotton bracket 8 is cleaned.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
