[0012] During the working process of the vacuum cleaner, the hose 31 can drag the vacuum cleaner body 10 to move on the ground while the handle is moving. Always moving backwards, the customer needs to continue to apply force to keep it moving forward
When the customer is cleaning downhill, the vacuum cleaner will automatically accelerate to the front of the customer, and the customer will lose control of the movement of the vacuum cleaner, causing great trouble to the user

Embodiment Construction
[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0034] Figure 3-6 Shown is the first embodiment of the present invention. In this embodiment, a cylindrical sleeve 52 is arranged on the vacuum cleaner body. After the roller 71 fixed at the center of the roller 70 is inserted into the sleeve 52, the roller 70 can be realized. It is rotatably connected to the vacuum cleaner body. An inner ring 73 is formed on the inner side of the roller 70 coaxially protruding inwardly, and an inner gear ring 72 is formed inside the inner ring 73 . A fixed shaft 55 is formed protruding outwardly directly under the sleeve 52, on which the balance arm 60 is rotatably fixed. Such as Figure 5 As shown, the left end of the balance arm 60 in this embodiment (equivalent to the direction in which the vacuum cl...

The invention discloses a dust collector which comprises a dust collector body and idler wheels rotatably arranged on the dust collector body, wherein each idler wheel is provided with an inner ring coaxially, and an internal ring gear is arranged inside the inner ring; a balancing arm is rotatably fixed on the dust collector body; and the left end of the balancing arm is a friction end, and a ratchet is arranged at the right end of the balancing arm, wherein moments at two sides of the fixing shaft of the balancing arm are same. When the dust collector is used for upslope cleaning, the dust collector body can be effectively prevented from sliding backwards, and further the burden of a user is reduced; and when the dust collector is used for down-slope cleaning, the rotation of the idler wheels can be effectively limited, excessive movement of the dust collector body can be prevented, and meanwhile, excessive movement of the dust collector body can be effectively limited, thus the satisfaction degree of users is greatly improved; in addition, the dust collector has the advantages of simple structure, easiness for realization, improvement on intelligent property of products and increase of competitiveness of products.
Description
technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a device capable of controlling the movement of the vacuum cleaner when it works on a slope. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vac...
