The cross bar of vertical runs, the resetting spring 4 are sleeved on the montant, and the other end of the resetting spring 4 is less than the cross
On bar.
In the present embodiment, the hairbrush 1 is radial hairbrush.
In the present embodiment, the other end of the montant is provided with the woollen brush base 2 installed for hairbrush 1, the woollen brush base 2 and hair
Brush 1 is fixedly connected.
In the present embodiment, brush head piston 16 is set and the brush head piston 16 is internally provided with brush head cavity 8, is in order to just
It can enter in brush head cavity 8 in compressed gas；
In the present embodiment, it is radially expanded the setting of set 5, is radially expanded on set 5 for the ease of the setting of U-shaped groove 13
The U-shaped groove 13 of setting be in order to when be radially expanded set 5 to far from the opening portion direction move when, the inclination of U-shaped groove 13
Face 15 pushes cross mandril 3 with 1 radial outward expansion of electric brush, realizes the radial outward expansion of hairbrush 1；And the cross
One end of mandril 3 is set as spherical part, be for the ease of hairbrush 1 by resistance when, the spherical part of cross mandril 3 can be along U-shaped
Groove 13 rotates, so that, along 13 circle rotation of U-shaped groove, rotating freely for hairbrush 1 is realized, with suitable conduit with electric brush 1
Internal relief region.
In the present embodiment, the cross bar and U-shaped part 12 are set, are for the limit to resetting spring 4, and setting reset bullet
Spring 4 is to be moved to close to the opening portion direction to when stopping being passed through compressed gas, be radially expanded set 5, in resetting spring
By cross mandril 3 with 1 radial contraction of electric brush under the action of 4, though hairbrush 1 in contraction or swelling state, all to pipe
Road inner wall has certain normal pressure, the secondary effect of friction is played, so cleanninfg brushes need not separately set annular friction pair.
In the present embodiment, the setting of the inner cover great circle ring portion and the outer cover great circle ring portion is to be radially expanded
Set 5 is sleeved between the inner cover great circle ring portion and the outer cover great circle ring portion, and convenient for being limited to radial expansion sleeve 5,
Guarantee is radially expanded set 5 and is axially moveable, and on the one hand guarantees that cross mandril 3 is accurately pushed to be moved outwards, another
Aspect when ensureing that be radially expanded set 5 moves backward in an axial direction, can make cross mandril 3 that diameter occur and inwardly move.
The present invention is passed through compressed air to the hairbrush cylinder, pressure in use, when needing to be cleaned using hairbrush 1
Contracting air enters in the brush head cavity 8 of brush head piston 16, and pressure increases in brush head cavity 8, and the drive of brush head piston 16 is radially expanded
Set 5 is moved to the direction far from the hairbrush cylinder entrance, is being radially expanded set 5 to the direction far from the hairbrush cylinder entrance
In mobile process, it is radially expanded the inclined surface 15 on set 5 in U-shaped groove 13 and is moved to the direction far from the hairbrush cylinder entrance
It is dynamic, to push cross mandril 3 (cross mandril 3 to be pushed radially outward to move to the direction movement far from brush head piston 16
It is dynamic), resetting spring 4 extends, during cross mandril 3 is moved radially outward by woollen brush base 2 push hairbrush 1 radial to
Outer expansion improves the cleaning performance of hairbrush 1 so that hairbrush 1 has normal pressure with inner wall of the pipe to be cleaned；In addition, in mandril machine
Under the action of the spherical part of structure, when hairbrush 1 receives resistance, the post rod mechanism is radially expanded 13 circumference of U-shaped groove on set 5
Direction is rotated, to make 1 spinning of hairbrush, to adapt to the uneven region of inner wall of the pipe to be cleaned so as to be cleaned
Each position of inner wall of the pipe can be cleaned.
When hairbrush 1 need not be used to be cleaned, stopping is passed through compressed air to the hairbrush cylinder, the reset of elongation
Spring 4 is shunk, and resetting spring 4 drives cross mandril 3 to move (i.e. 3 diameter of cross mandril to close to the direction of brush head piston 16
To moving inward), cross mandril 3 is radially-inwardly shunk by woollen brush base 2 with electric brush 1, and cross mandril 3 pushes radial swollen
Expansion set 5 is moved to close to the direction of the hairbrush cylinder entrance, is radially expanded set 5 and is driven brush head piston 16 to close to the hairbrush
The direction of cylinder entrance is moved, the compressed air in discharge brush head cavity 8, is used so as to expansion next time of hairbrush 1.
The above is only presently preferred embodiments of the present invention, is not imposed any restrictions to the present invention, every according to the present invention
Technical spirit changes any simple modification, change and equivalent structure made by above example, still falls within skill of the present invention
In the protection domain of art scheme.
