Problems solved by technology

However, the above structure has the following defects: the floor brush motor is placed outside the roller brush, which takes up a lot of space, so the floor brush of the vacuum cleaner must be made very large, and the space utilization rate is not high
However, this structure is more complicated, and the assembly process is not simple. In addition, the driving motor needs to be replaced or maintained due to frequent use, and this structure is not easy to disassemble.

Embodiment 1

[0074] The improvement of the present invention mainly lies in the fixed position of the ground brush motor, such as figure 2 , Figure 7 As shown, in this embodiment, the ground brush motor 8 in the rolling brush assembly 26 is all located inside the rolling brush body 5, and the transmission gear 3, the first gear 7 and the second gear 12 are all located on the right side of the ground brush motor 8, The second gear 12 is integrally formed inside the rolling brush body 5 .

[0075] Both sides of the wheel surface of the transmission gear 3 are provided with bosses, and the bosses on each side are respectively connected with the left end cover 1 of the rolling brush and the first support frame 6 of the transmission gear through bearings 4 .

[0076] The roller brush body 5 is connected to the two ends of the concave cavity 12A in the vacuum cleaner or the two ends of the cavity 12B in the vacuum cleaner nozzle through the left end cover 1 of the roller brush and the right e...

Embodiment 2

[0081] Such as image 3 As shown, the difference between Embodiment 2 and Embodiment 1 is that a part of the ground brush motor 8 in the roller brush assembly 26 is located inside the roller brush body 5 , and the other part protrudes from the left end cover 1 of the roller brush. The remaining part of the ground brush motor 8 protrudes from the left end cover 1 of the roller brush and is located outside the roller brush body 5. The advantage of this structure is that a part of the ground brush motor 8 is placed outside the roller brush, shortening the distance between the ground brush motor 8 and the roller brush. The placement position inside the brush body 5 can reduce the size of the rolling brush body 5 .

Embodiment 3

[0083] Such as Figure 4 As shown, the difference between embodiment 3 and embodiment 1 mainly lies in that: the roller brush body 5 is coaxially provided with a support frame 17, and the support frame 17 is provided with a cavity, and a support frame cover 28 closes the cavity, and the support frame A set of bearing devices are respectively provided at both ends of 17, and the bearing devices include a first bearing support frame 11 and a first bearing 10.

[0084] One end of the ground brush motor 8 is connected to the first bearing 11, which can limit the axial movement of the ground brush motor 8 and bear the radial load. The outer ring of the first bearing 11 cooperates with the first bearing support frame 10, and the function of the support frame 17 is to support the right end cover 2 of the roller brush. The transmission gear 3 is fixed on the first first transmission gear support frame 6, the first transmission gear support frame 6 is connected with the first bearing ...

Abstract

The invention belongs to the field of household cleaners and particularly relates to a vacuum cleaner and a suction nozzle thereof. The vacuum cleaner and the suction nozzle thereof comprise a ground brush motor and a rolling brush body, wherein the ground brush motor is arranged in the rolling brush body; a first gear is connected with the ground brush motor; a transmission gear is engaged with the first gear and a second gear respectively; the second gear which is fixed in the rolling brush body drives the rolling brush body to rotate; and a rolling brush left end cover and a rolling brush right end cover are connected with two ends of a ground brush base respectively. According to the vacuum cleaner, the ground brush motor is arranged in the rolling brush body, so that the vacuum cleaner has a compact structure, can be simply assembled, and is convenient to disassemble. The selected gears are plastic products which have high strength, are high-temperature-resistant and wear-resistant, and have certain lubricating properties, so that the noise can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of household cleaners, and in particular relates to a vacuum cleaner and a suction nozzle thereof. Background technique [0002] For general vacuum cleaners, the ground brush motor is placed outside the roller brush, such as figure 1 As shown, the roller brush drives the roller brush body to rotate through a belt or a synchronous belt. The roller brush body is planted with hairs. When rotating, the hair on the roller brush body hits the surface of the carpet, and the dust on the carpet is separated from the carpet. One of the ports is connected to the pipe, and the negative pressure generated by the main motor is transmitted to the brush cavity through the pipe and this port, and the dust is sucked away by the negative pressure, and then the dust is collected in the dust collection area through the separation device. The two ends of the roller brush remain stationary and are fixed on the ground brush base. Among the...
