Description
Technical field
The present invention relates to a kind of screen pipe, the screen pipe on especially a kind of dust catcher.
Background technology
The phenomenon of blocking occurs in the screen pipe generally existing being used on vacuum cleaner on the market at present, so that
The filter effect of screen pipe is not good.
To problem above, it is badly in need of us and solves.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of production cost and good filtration effect of reducing
Screen pipe on dust catcher.
In order to achieve the above object, the screen pipe on a kind of dust catcher designed by the present invention, it includes filtering tube body
And connecting tube, filtering tube body is in the unclosed and hollow tubular body structure in two ends, the cylindrical weekly form in screen pipe body axial direction
Multiple rows of filter bores are provided with identical spacing on face, one end and filtering tube body wherein one end of connecting tube are attached, and connection
One obtuse angle of central axis formation of the central axis of pipe and filtering tube body, and the angle at the obtuse angle is 100~150 °；Even
The end of the adapter other end is outward extended with block, and draw ring is additionally provided with the external peripheral surface of connecting tube axial direction.
Preferably, the external peripheral surface in filtering tube body with connecting tube junction is provided with the groove concaved, and it is recessed
The two ends of groove connect and form loop configuration.
Preferably, being additionally provided with two connecting holes in the one end for the filtering tube body being connected with connecting tube, connecting hole is in circle
Shape or rectangular configuration, and the central axis coincidence of two connecting holes.
Preferably, the orthographic projection of each filter bores is rounded, oval or rectangle in one kind.
In accordance with the above, the screen pipe on a kind of dust catcher designed by the present invention, by unique structure design,
So that filter effect is more preferably, and the form of connection is also more convenient.Therefore, it has simple in construction, easy to use and reasonable in design
The features such as.
Brief description of the drawings
Fig. 1 is front view of the invention；
Fig. 2 is top view of the invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the screen pipe on a kind of dust catcher of the present embodiment description, it includes the filtering He of tube body 1
Connecting tube 2, filtering tube body 1 is in the unclosed and hollow tubular body structure in two ends, the cylindrical weekly form in the axial direction of filtering tube body 1
Filter opening 3 is drained through provided with eight with identical spacing on face, the orthographic projection of each filter bores 3 is rectangular；One end of connecting tube 2 and screen pipe
The wherein one end of body 1 is attached, and one obtuse angle of central axis formation of the central axis and filtering tube body 1 of connecting tube 2,
And the angle at the obtuse angle is 120 °；Block 4 is outward extended with the end of the other end of connecting tube 2, in the outer of the axial direction of connecting tube 2
Draw ring 5 is additionally provided with circumferential surface, two connecting holes 6 are additionally provided with the one end for the filtering tube body 1 being connected with connecting tube 2, even
Connect that hole 6 is in rectangular configuration, and the central axis of two connecting holes 6 is overlapped.
