This invention relates to a vacuum cleaner with a downward-facing suction chamber on the front side of the floor brush in the direction of travel, and an upward-facing nozzle on the top of the connector. The forward or backward movement of the vacuum cleaner applies different forces to the handheld part. Simultaneously with the floor brush moving forward or backward, the connector to the handheld part swings back and forth relative to the floor brush. Because the wheel assembly is linked to the connector, when the connector swings forward, the wheel assembly moves downward, causing the bottom wall of the floor brush to tilt downwards from back to front. This creates a first gap between the bottom wall of the floor brush and the surface to be cleaned, allowing debris and dust to enter. This ensures that when the vacuum cleaner moves backward, there is sufficient space at the rear of the vacuum cleaner for dust and debris to be sucked into the suction chamber. Therefore, even if some debris or dust is missed when the vacuum cleaner moves in any direction, it can be cleaned by reversing the vacuum cleaner without needing to change direction.
Description
Technical Field
The invention relates to the field of dust removing equipment, in particular to a dust collector.
Background
In the existing negative pressure cleaning devices, such as a sweeping robot, a handheld dust collector and the like, the travelling direction of the negative pressure cleaning device defaults to the cleaning direction of the device, namely, the cleaning suction ports of the cleaning device are all positioned on the front side of the travelling direction, so that the cleaning effect is better when the device is advanced, and the dust removing effect is poor when the device is moved reversely. Because missing sundries and dust can appear in many times in the cleaning process, the equipment is required to turn around and walk once again from the original route, and the cleaning process is very inconvenient.
The Chinese patent with the patent number of CN201210342193.X discloses a floor brush of a dust collector with double suction ports, wherein the floor brush is respectively provided with a front suction port and a rear suction port at the front and the rear of a base, a guide hole is arranged at the downstream of an air inlet of the floor brush, and an air flow channel positioned at the upstream of the guide hole is formed between an upper fan cover and a lower fan cover. Through the arrangement of the front suction port and the rear suction port, the problems that the existing floor brush cannot be cleaned or the cleaning effect is not ideal due to the fact that the existing floor brush retreats are solved. However, this double suction port design still has certain drawbacks. On one hand, the rear suction port breaks the original structure of the whole air duct design, a channel matched with the rear suction port occupies the suction flux of the total suction channel to influence the dust collection effect of the front suction port, on the other hand, the rear suction port moves backwards relative to the front suction port, the ground clearance of the whole machine is unchanged, dust and sundries which cannot be sucked in the advancing process still cannot be sucked smoothly after the rear suction port moves backwards.
The Chinese patent application No. CN200580004495.4 discloses a floor dust collection port for a dust collector, wherein the front end and the rear end of a roller (4) of the floor brush (1) are provided with baffle bars, the baffle bars advance or retreat, the corresponding baffle bars can be moved upwards, a suction port which is originally downward is further formed, and a side seam is formed at the front side or the rear side, so that the repeated dust collection of the carpet and other positions which are difficult to remove dust can be conveniently carried out from the side seam. However, the design of the dust collection opening which is changed up and down has better dust collection effect on flexible surfaces such as carpets, but has poor dust collection effect on sundries on the ground, and still does not accord with the conventional dust collection environment.
