Problems solved by technology

[0002] With the improvement of people's living standards, vacuum cleaners have entered more and more families as a cleaning device. The structure of the floor brush as an accessory of the vacuum cleaner has a great impact on its cleaning effect. The brush body does not have the function of suspension and lifting, and only the cleaning method of row brush or disk brush lifting is used. For example, the Chinese patent application with application number 201420031521.9 discloses a floor scrubber disk brush, which is realized by moving up and down the pedal bracket. The lifting of the disc brush, but how to use the brush body on the lifting mechanism to ensure the high efficiency and labor saving of the floor brush has become an urgent problem for sanitary ware manufacturers to solve
The Chinese patent application with application number 201420440301.1 discloses a carpet cleaning machine that directly adjusts the squeegee through the adjustment rod, but its structure is complicated, the squeegee mouth and the brush body are relatively fixed, and the brush body cannot be raised and lowered alone
The Chinese patent application with the application number 200910024598.7 discloses a pneumatic carpet cleaning machine, which uses a nozzle switching valve to open and close the nozzle to adjust the working state of the brush body and the suction nozzle, but the brush body cannot be lifted up and down, which cannot solve the problem of the brush body staying on the ground. The pollution problem, and the valve needs to be pulled by hand, and it is quite inconvenient to bend over to operate
If the brush body cannot be raised and lowered, the brush body will keep in contact with the ground when the cleaning work is over, because the brush body will be hung with stains and a large amount of sewage, which will affect the suction of the floor brush nozzle, thereby affecting its cleaning effect, and for different ground or The surface of the carpet, the brush body of the vacuum cleaner may cause damage to it when cleaning

Embodiment 1

[0026] figure 1 It is a schematic cross-sectional view of the first embodiment of the present invention when the end of the brush body is in the floating position. Such as figure 1 As shown, the floor brush provided by the present invention mainly includes a floor brush body 100, a brush body assembly 200 disposed on the floor brush body, a driving assembly for driving the rotation of the brush body assembly 200, and an elastic linkage assembly. The brush body assembly 200 includes a brush body end and a force receiving end, the brush body end is connected to the brush body 210, and the brush body assembly 200 is rotatably connected to the floor brush main body 100 through a connecting shaft 110 arranged between the brush body end and the force receiving end The end of the brush body is elastically connected to the ground brush body 100 through an elastic linkage assembly. In this embodiment, the driving assembly is a pedal assembly 400, and the force-bearing end is arranged...

Embodiment 2

[0040] Figure 6 It is a schematic cross-sectional view of the second embodiment of the present invention when the brush body end is in the floating position; Figure 7 It is a schematic cross-sectional view of the second embodiment of the present invention when the end of the brush body is in the ground position. Such as Figure 6 combine Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the pedal assembly 400' is different. The pedal assembly 400' includes a pedal 401 and a support rod fixed at the lower end of the pedal, and the support rod includes a first support rod 402' and the second support rod 403'; the active end is the lower end of the first support rod 402' and the second support rod 403', that is, the lower end of the first support rod 402' and the second support rod 403' and the brush body assembly 200 The force-bearing ends of the brush body assembly 200 are pushed against each other to provide force for the...

Embodiment 3

[0044] Figure 8 It is a schematic cross-sectional view of the brush body end of the third embodiment of the present invention when it is in the floating position; Figure 9 It is a schematic cross-sectional view of the third embodiment of the present invention when the end of the brush body is in the ground position. Such as Figure 8 combine Figure 9 As shown, the driving assembly in this embodiment is a pedal assembly, and the pedal assembly 400" is T-shaped, including a pedal 401 and a first support rod 402" fixed at the lower end of the pedal 401. The brush body assembly 200' can be Rotationally connected to the main body of the floor brush 100', the corresponding position at the bottom of the pedal assembly 400", that is, the lower end of the first support rod 402" is against the force-bearing end of the brush body assembly 200' to provide force for the brush body assembly 200'. The brush body assembly 200' mainly includes a brush body 210 and a support link 220', wh...

Abstract

The invention discloses a ground brush and a dust collector. The ground brush comprises a ground brush main body (100, 100') and a brush body assembly (200, 200') arranged on the ground brush main body, wherein the ground brush main body is provided with a nozzle (300) and a sucker connected therewith; one end of the brush body assembly is a brush body end connected with the brush body (210); the brush body assembly is rotationally connected with the ground brush main body through a connecting shaft (110, 110'); the brush body end is elastically connected with the ground brush main body through an elastic linking assembly; the ground brush also comprises a driving assembly for driving the brush body assembly to rotate and a switching locking apparatus (510) which is alternately in a released state or a locked state through the action of the driving assembly; the brush body is rotated under the driving of the driving assembly and switched between two operating positions, namely the brush body is in a ground-affixed or suspension position under the elastic effect of the elastic linking assembly when the switching locking apparatus is in the released state; and the brush body is in the suspension or ground-affixed position when the switching locking apparatus is in the locked state.
