Abstract
The invention relates to a dust absorption mouth for a vacuum cleaner, including a brush, a joint arranged on the brush, a connecting rod connected on the joint. A connecting channel is connected in the joint, and the brush is communicated with the connecting tube by the connecting channel, wherein the joint is rotatablely arranged on the illuminate around the first axis, and the connecting tube is rotatablely arranged on the joint around the second axis. The first axis is perpendicular to the second axis. The dust absorption mouth can rotate around two orthogonal axes, thereby the suction nozzle not only can adsorb the lower cleaning surface, such as the bottom of the bed, the bottom of the wardrobe etc; moreover the invention can adsorb the higher cleaning surface such as the top of the wardrobe, the altitude of the wall etc. The dust absorption mouth with the structure can effectively solve the problems in the daily life caused by the dumb joint of the brush, moreover when operating, only the wrist is needed to swing, which liberates the arm and is comfortable.

But the existing overwhelming majority's dust absorption nozzle all can only be realized motion can't realizing omnibearing motion in the angle of certain limitation, and when rotated, operator's arm must follow brush body to move together.Dust absorption nozzle is being inhaled brush as eminence or very can not be exhaustive during lower very.Must there be shortcomings such as inconvenient operation, effort.
Summary of the invention
The object of the present invention is to provide a kind of dust absorption nozzle that is used for vacuum cleaner, this dust absorption nozzle can on tube connector can be around two orthogonal axial lines rotations.
In order to reach above purpose, the scheme that the present invention adopts is: a kind of dust absorption nozzle of vacuum cleaner, comprise brush body, be arranged on the joint on the described brush body, be connected the tube connector on the described joint, be provided with interface channel in the described joint, described brush body is connected with described tube connector by described interface channel, described joint can be arranged on the described brush rotatably around first axial line, described tube connector can be arranged on the described joint rotatably around second axial line, and described first axial line and described second axial line are perpendicular.
Described joint is provided with first connecting portion that communicates with described interface channel in an end that is positioned at described interface channel, the outer wall of described first connecting portion is provided with first annular groove, the center line of this first annular groove and described second axial line coincide, the inwall of described tube connector has first boss that is complementary with described first annular groove, described first boss has at least part to be limited in described first annular groove, and described first boss can be along described annular groove rotation.
The outer face of described first boss is provided with convex tendon, and described joint is provided with the stairstepping seal area in the notch near described first annular groove, and described convex tendon pushes against at described joint and is positioned on the wall at described seal area place.
Described boss is closed annular boss.
Described joint is provided with second connecting portion that communicates with described interface channel in an end that is positioned at described interface channel, the outer wall of described second connecting portion is provided with second annular groove, the center line of this second annular groove and described first axial line coincide, offer installing hole on the housing of described scrubbing brush, has second boss that is complementary with described second annular groove on the inwall of this installing hole, described second boss has at least part to be limited in described second annular groove, and described second boss can be along described annular groove rotation.
Because the present invention has adopted above technical scheme, its advantage is: by making that whole dust absorption nozzle can be around two orthogonal axial lines rotations, like this, suction nozzle not only can inhale brush lower cleaning look like bed at the bottom of, bottom, clothing kitchen etc.; Look like wardrobe top, wall eminence etc. but also can inhale the higher cleaning of brush.The dust absorption nozzle of this structure can effectively solve in the real life because the dumb problems of bringing such as inconvenience in brush body joint, and only need swing wrist during operation, has liberated arm, and is more comfortable.

The specific embodiment
Referring to the dust absorption nozzle of a kind of vacuum cleaner shown in each accompanying drawing 1～6, it by brush body 3, be arranged on the joint 2 on the brush body 3 and 1 three parts of tube connector of being connected on the joint 2 are formed.
Be provided with interface channel 15 in the joint 2, brush body 3 is connected with tube connector 1 by interface channel 15, and dust just can flow in the tube connector 1 in scrubbing brush 3 by this interface channel 15 like this.Joint 2 can be arranged on the brush 3 rotatably around first axial line 4, as shown in FIG., this first axial line 4 is positioned at vertical guide, and tube connector 1 can be around first axial line, 4 rotations, 0～360 degree, tube connector 1 also can be arranged on the joint 2 rotatably around second axial line 5, as shown in FIG., first axial line 4 and second axial line 5 are perpendicular, first axial line 4 is a horizontal direction, and generally, 3 of tube connectors need rotation 0～180 degree to meet the demands, a pair of convex shoulder 16 is set on joint 2 in the present embodiment, tube connector 1 can only rotate between two convex shoulders 16 around 4 rotations of first axial line time like this, and two convex shoulders 16 play spacing effect.
In order to make tube connector 1 the time around 5 rotations of second axial line, can not produce gas leak phenomenon, the outer face of first boss 8 is provided with convex tendon 9, joint 2 is provided with stairstepping seal area 10 in the notch near first annular groove 7, convex tendon 9 pushes against at joint 2 and is positioned on the wall at seal area 10 places, so just can reach good sealing effectiveness.
