Description

Cleaning machine

Technical Field

The invention relates to the field of dust removing equipment, in particular to a cleaning machine.

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, and a channel matched with the rear suction port occupies the suction flux of the total suction channel, so that the dust collection effect of the front suction port is affected; on the other hand, the rear suction port is only moved backward relative to the front suction port, the ground clearance of the whole machine is unchanged, dust and sundries which cannot be sucked in when advancing are still not sucked in smoothly after retreating.

The Chinese patent application No. CN200580004495.4 discloses a floor cleaning mouth for a dust collector, wherein the floor brush is provided with a baffle strip at the front end and the rear end of a roller, and the baffle strip can move upwards when moving forwards or backwards, so that a suction port which is originally downward is formed, and a side seam is formed at the front side or the rear side, thereby being convenient for repeatedly removing dust from the side seam to the position which is difficult to remove dust, such as a carpet. 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.
