When the connecting pipe 13 rotates counterclockwise around the connecting pipe rotating shaft 14 from the first state, the driving block located at the front end of the connecting pipe 13 synchronously rotates counterclockwise around the connecting pipe rotating shaft 14, the driving surface 19 abuts against the driven surface 20 on the side surface of the swing hook 16, as the driving surface 19 continues to rotate counterclockwise around the connecting pipe rotating shaft 14, the contact area between the driving surface 19 and the driven surface 20 is gradually increased, the swing hook 16 is pushed to rotate clockwise around the swing hook rotating shaft 17 until the hook tip 18 is embedded between the adjacent hubs 15, the roller 12 is prevented from rotating, at this time, as shown in fig. 6, the driving block and the driven block abut together, specifically, the upper arc surface 21 abuts against the lower part of the driven surface 20, and at this time, the included angle α 2 (for example, α 2 ≦ 115 °) between the connecting pipe 13 and the main body 11 is relatively small, the tail end of the connecting pipe 13 is far away from, the storage state (second state) is entered.
When the connecting pipe 13 rotates clockwise and backwards around the connecting pipe rotating shaft 14 from the second state, the driving block synchronously rotates clockwise around the connecting pipe rotating shaft 14 until the driving block is separated from the contact with the driven block, at the same time, the hook tip 18 of the swing hook 16 rotates anticlockwise due to self gravity until the driving block is separated from the contact with the hub 15, the roller 12 is free again, and the dust collector suction nozzle 10 enters the first state and can rotate freely on the surface to be cleaned.
Effects and effects of the embodiments
According to the suction nozzle of the dust collector, the suction nozzle comprises the braking mechanism, the braking mechanism is arranged between the roller and the connecting pipe and is provided with the wheel hub and the swing hook, the wheel hub is arranged on the inner side of the roller, and the swing hook is provided with the hook point, so when the hook point is abutted against the wheel hub, the rotation of the roller is limited; when the hook point leaves the hub, the roller can rotate freely, namely, the rotation of the roller can be controlled through the braking mechanism.
According to the utility model relates to a dust catcher because have the dust catcher suction nozzle, the dust catcher suction nozzle has arrestment mechanism, consequently, when the dust catcher need stand, arrestment mechanism can prevent the gyro wheel of dust catcher suction nozzle to rotate for this dust catcher can lean on wall body or similar firm support and stand, and the dust catcher suction nozzle can not slide forward, and the dust catcher is whole can stably stand promptly, is difficult to drop.
Furthermore, the connecting pipe is provided with the driving block, so that when the connecting pipe is rotated, for example, the connecting pipe is rotated forwards, the driving block can rotate forwards along with the connecting pipe, so that the driving block is abutted to the driven block, the swing hook is further pushed to swing, the hook tip is abutted to the hub, and the roller is prevented from rotating; when the connecting pipe is rotated backwards, the driving block is separated from the driven block, and the hook tip is separated from the hub, so that the roller can rotate freely. The control of the rolling state of the roller can be realized only by rotating the connecting pipe, so that the switching between the dust collection state and the standing state against the wall (object) of the dust collector is realized, and the use is very convenient.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
For example, in the present embodiment, the swing hook 16 is located forward of the roller pivot 17, and the hook tip 18 extends forward. In practical applications, the swing hook 16 may be disposed behind the roller shaft, and the hook tip 18 may extend rearward and point toward the hub 15 disposed behind the roller shaft. When the driving surface 19 is adjusted accordingly, so that the connecting pipe 13 rotates counterclockwise and forward and upward from the first state, the driving surface 19 can push the swing hook 16 to rotate counterclockwise, so that the hook tip 18 swings backward until abutting against the hub 15, and the vacuum cleaner nozzle 10 is turned from the first state to the second state. When the connecting pipe 13 is rotated clockwise and backwards from the second state, the driving surface 19 is out of contact with the swing hook 16, the gravity of the swing hook 16 drives the swing hook 16 to rotate clockwise, so that the hook tip 18 is out of contact with the hub 15, and the vacuum cleaner nozzle 10 enters the first state.
