The specific embodiment
To shown in Figure 7, electric brush of vacuum cleaner of the present invention comprises torque arm 20, brush holder 30 as Fig. 4.Torque arm 20 rotatably is fixed on the inboard of the dust suction headstock (figure slightly).Brush holder 30 is encircled above-mentioned torque arm 20, and it is fixed.
Two sides of above-mentioned dust suction headstock inboard are formed with and are pressed into dish 12,14, and this is pressed into and forms porose 12a on the dish 12,14, and torque arm 20 is inserted among the 12a of hole.
One end 20a of above-mentioned torque arm 20 is inserted among the above-mentioned hole 12a in the mode that is pressed into, and is fixed on to be pressed into dish 12, and other end 20b rotatably is inserted among the above-mentioned hole 12a, is installed in to be pressed into dish 12.That is, when above-mentioned torque arm 20 applied active force, one end 20a was fixed, and be not rotated, and other end 20b is rotated.After this torque arm 20 receives above-mentioned revolving force, under the elastic force effect, set back, rotate said brush frame 30.
In addition, the section configuration of above-mentioned torque arm 20 is circular.And the hole 12a that is pressed into dish 12 also has circle.Therefore processing is pressed into and coils 12 hole 12a easily.
Said brush frame 30 comprises bottom brush holder 32 and top brush holder 34.Bottom brush holder 32 is formed with bristle 40, and bristle contacts with the foreign matter on ground, makes foreign matter floating.Top brush holder 34 combines with bottom brush holder 32, and fixedly torque arm 20.Be formed with groove 35 on above-mentioned top and the bottom brush holder 34,32.Above-mentioned torque arm 20 is clipped in the above-mentioned groove 35.Because torque arm 20 is clipped in the above-mentioned groove 35, rub, when brush holder 30 rotations, revolving force can pass to above-mentioned torque arm 20.
To shown in Figure 10, above-mentioned torque arm 50 is the cuboids with rectangular cross section shape as Fig. 8, also has rectangle and be formed on the hole 62a that is pressed into dish 62.Therefore, when torque arm 50 was rotated by brush holder 72,74, the torque arm 50 that can prevent to be pressed among the above-mentioned rectangular opening 62a slided from being pressed into dish 62.The groove 75 of the brush holder 72,74 that contacts with cuboid torque arm 50 surfaces also has rectangular cross section, therefore can rotate torque arm 50 more effectively.
Consult Fig. 4 to Fig. 7, the assembling process in the embodiment of the invention is elaborated.
At first, the above-mentioned dish that is pressed into 12,14 is fixed on the dust suction headstock (not shown).One end 20a of torque arm 20 is pressed among the hole 12a that is pressed into dish 12, is fixed on to be pressed into dish 12 under the frictional force effect; The other end 20b of torque arm 20 is rotatably installed in opposite side and is pressed on the dish 14.
Afterwards, at the upper and lower sides of torque arm 20, top brush holder 32 and bottom brush holder 34 are installed, the outside of torque arm 20 is sandwiched in the groove 35 of brush holder 30.The assembling of fixed parts such as top brush holder 32 and bottom brush holder 34 usefulness screws 16.Drive division makes said brush frame 30 carry out back and forth movement within the specific limits.Above-mentioned torque arm 20 is pressed the certain angle rotation, and is carried out back and forth movement under the effect of brush holder 30.And torque arm 20 is fixed on the brush holder 30 that carries out back and forth movement.Therefore, torque arm 20 receives the power of brush holder 30, after receiving above-mentioned power, under the elastic force effect of self, recover, and rotation.In this process, the bristle 40 that is formed on bottom brush holder 32 contacts with foreign matter, makes foreign matter floating.
In a word, above-mentioned torque arm 20 is fixed on the above-mentioned dish 12 that is pressed in the mode that is pressed into.Therefore be pressed into dish 12 and can have thin thickness, and need not use fixed part as existing vacuum cleaner.Therefore can conserve space.
The invention effect
The mode of vacuum cleaner of the present invention by being pressed into is fixed on torque arm on the dust suction headstock. Cause This does not fixedly need to use fixed part during torque arm, can enlarge the cleaning scope of powered brush.
