Example one
The embodiment provides a dust cup, which is shown in fig. 1 to 6 and comprises a cup body 1, wherein the cup body 1 surrounds the outer side of a filter screen cover 2; still including being located and being used for carrying out the dust removal 9 that removes dust to filter screen panel 2 outer wall between filter screen panel 2 and the cup 1, when getting and putting the cup, dust removal 9 removes in order to remove dust to filter screen panel 2 on filter screen panel 2 outer wall. One end of the dust removing piece 9 is connected with the inner wall surface of the cup body 1, the other end of the dust removing piece 9 is a suspension end, and the suspension end is in contact with the filter screen 2.
Compared with the prior art, the dust cup that this embodiment provided is equipped with dust removal piece 9 between filter screen panel 2 and cup 1. When needs clear up the outer wall that filters screen panel 2, filter screen panel 2 and cup 1 relative motion, cup 1 drives dust removal piece 9 and takes place to deform, filtering screen panel 2 surface removal, clear up the outer wall that filters screen panel 2, make and adsorb in the dust collection area that filters screen panel 2's outer wall, matters such as dust, hair come off and directly get into cup 1 from filtering screen panel 2, realize filtering screen panel 2's clearance, thereby can guarantee to filter screen panel 2's filter effect. Simultaneously, adopt the dirt cup of this kind of structure, at the in-process of taking out cup 1, the piece 9 that removes dust can clear up the outer wall of filter screen panel 2 automatically, need not manually again to clear up it, and easy operation can effectively promote user experience and feel.
It should be noted that, when the cup body 1 and the filter screen 2 are restored to the assembled position, the dust removing member 9 is also sleeved on the filter screen 2 again.
Illustratively, the dust removing member 9 is annular, an outer annular end of the annular is connected with the inner wall surface of the cup body 1, and an inner annular end of the annular is a free end. The dust removing member 9 is formed on the inner wall surface of the cup body 1 by secondary injection molding by using an elastic material.
In order to clean the whole outer wall surface of the filter screen cover 2, the dust removing piece 9 is positioned at one end of the cup body 1 close to the dust collecting device host. In this way, the movement of the dust removing member 9 can cover substantially the entire outer wall surface of the filter mesh enclosure 2, so that the dust removing effect of the dust removing member 9 can be improved.
Considering that the filter screen 2 needs to be cleaned, a relative motion is required between the cup body 1 and the filter screen 2, and for example, the connection between the cup body 1, the filter screen 2 and the host of the dust collecting device can be implemented in the following two ways: in the first mode, the filter screen 2 is detachably and fixedly connected with the cup body 1, the cup body 1 is detachably and fixedly connected with the dust collection equipment main machine, when the filter screen 2 needs to be cleaned, the cup body 1 and the filter screen 2 are integrally taken down from the dust collection equipment main machine, then the filter screen 2 is taken out from the cup body 1, in the taking-out process, the cup body 1 and the filter screen 2 generate relative motion, and the dust removing piece 9 cleans the outer wall surface of the filter screen 2; in the second mode, the filter screen 2 is fixedly connected with the dust collector host, the cup body 1 is detachably and fixedly connected with the dust collection device host, and the cup body 1 can move along the axial direction of the dust collection device host. When needs cleared up filtering screen panel 2, take off cup 1 from the dust collecting equipment host computer, at the in-process of taking off, cup 1 and filtering screen panel 2 produce relative motion, and the piece 9 that removes dust is to clearing up filtering screen panel 2's outer wall.
It should be noted that, from the point of view of the brief cleaning process and the experience of the user, the second mode is selected for connection among the cup body 1, the filter screen 2 and the dust collecting device host. This is because, when getting put cup 1, cup 1 along the axial displacement of host computer, like this, getting of cup 1 can not take place to interfere with filtering screen panel 2 to can filter screen panel 2 and dust collecting equipment host computer fixed connection, need not to filter screen panel 2 and take off, only take off cup 1 clean can, thereby can effectively simplify dirt cup clearance flow. Simultaneously, when cup 1 is clean, compare in cup 1 and take off with filtering screen panel 2 simultaneously, only take off the dirt cup and can reduce the flow of filtering screen panel 2 and dust collecting equipment host computer deuterogamy, make things convenient for the deuterogamy of cup 1 and dust collecting equipment host computer.
For example, the detachable connection between the cup body 1 and the dust collection device main unit can adopt a magnetic attraction manner, that is, one end of the cup body 1 close to the dust collection device main unit is provided with a magnetic attraction piece, and correspondingly, one end of the dust collection device main unit close to the cup body 1 is provided with a magnetic attraction matching piece. Like this, when cup 1 was close to the dust collecting equipment host computer, through the magnetic attraction between piece and the fitting piece of inhaling, can realize automatic assembly and the separation under the exogenic action between cup 1 and the dust collecting equipment host computer.

Like this, inhale the piece and inhale the fitting piece with magnetism through composite construction's magnetism, can effectively improve magnetism and inhale the piece and inhale the magnetic attraction between the fitting piece, and then improve the connection stability between cup 1 and the dust collecting equipment host computer.
It should be noted that the magnetic attraction function of the magnetic attraction member and the magnetic attraction mating member can be realized by forming a magnetic attraction layer on the surfaces of the contact member 4 and the interference member 5 or embedding a magnetic attraction material in the contact member 4 and the interference member 5.
In order to further improve the connection stability between the cup body 1 and the main unit of the dust suction device, a protrusion and a groove 8 matched with the protrusion are arranged between the contact member 4 and the abutting member 5, the protrusion comprises a rigid protrusion 6 and an elastic protrusion 7 sleeved outside the rigid protrusion 6, the elastic protrusion 7 is trapezoidal, the groove 8 is also trapezoidal, and the trapezoid is positioned at the bottom of the groove 8. This is because the rigid projections 6 are able to give the projections sufficient structural strength; simultaneously, adopt trapezoidal elastic bulge 7 and recess 8 to mutually support, the side of recess 8 can carry out effectual spacing to elastic bulge 7 to can further improve the connection stability between cup 1 and the dust collecting equipment host computer, reduce the condition emergence that the dirt cup drops from the dust collecting equipment host computer in the work vibration process.
In order to realize the dust collection function of the dust cup, the dust cup further comprises an end cover 10 arranged on the front end face of the cup body 1, a fluid pipeline arranged in the cup body 1 and a fluid inlet 11 arranged on the end cover 10, the fluid pipeline is communicated with the fluid inlet 11, the end cover 10 corresponds to the fluid inlet 11, and a dust collection area is formed in an area between the fluid pipeline and the cup body 1.
In order to improve the applicability of the cup body 1, the diameters of a plurality of radial cross sections of the cup body 1 are not completely the same in the axial direction of the cup body 1. Illustratively, along the axial direction of the cup body 1, the cup body 1 comprises a plurality of sub-cup bodies with gradually increasing diameters, that is, the cup body 1 has a stepped structure; alternatively, the cup body 1 may have a truncated cone shape or a tapered shape. In this way, since the diameters of the different positions of the cup body 1 are different, the user can select the holding area on the outer wall surface of the cup body 1 according to the size of the palm of the user, specifically, if the palm of the user is small, the holding area can select the area corresponding to the outer wall surface of the cup body 1 having a small diameter, and if the palm of the user is large, the holding area can select the area corresponding to the outer wall surface of the cup body 1 having a large diameter.
From the viewpoint of stress balance, in order to improve the use comfort of the user, the cup body 1 and the filter screen 2 are coaxially arranged, that is, the axis of the cup body 1 coincides with the axis of the filter screen 2.
For the structure of the dust removing part 9, in order to facilitate the switching of the dust removing part 9 between the assembling state or the moving state and the free state, specifically, the dust removing part 9 includes a first elastic part, a second elastic part and a dust removing part, one end of the first elastic part and one end of the second elastic part are respectively connected with the inner wall surface of the dust cup body 1, the other end of the first elastic part and the other end of the second elastic part are connected to form a common end, the dust removing part is connected with the common end, and the radial cross-sectional shapes of the first elastic part, the second elastic part and the inner wall surface of the dust cup body 1 are triangular. Therefore, when the dust removing part swings towards the direction close to the host machine, the first elastic part is stretched, and the second elastic part deforms towards the inside of the triangle; when the dust removing part swings towards the direction far away from the host, the second elastic part is stretched, and the first elastic part deforms towards the inside of the triangle.
In consideration of the fact that the first elastic portion and the second elastic portion mainly function as a connecting portion and need to have good elasticity, the dust removing portion is mainly used for removing dust on the outer wall surface of the filter screen cover 2, and therefore the elastic modulus of the first elastic portion and the second elastic portion is smaller than that of the dust removing portion.
In consideration of the fact that the dust removing member 9 is not limited by other components in a free state, in order to ensure that the dust removing member can incline towards the direction close to the main machine, the length of the first elastic part is larger than that of the second elastic part of the dust removing member 9 in the free state, that is, the radial cross-sectional shapes of the first elastic part, the second elastic part and the inner wall surface of the dust cup body 1 are unequal-waisted triangles. Thus, in the free state, the dust removing unit can be promoted to incline toward the main body.
