Description

Sewage collection device for surface cleaner and surface cleaner

Technical Field

The utility model relates to the technical field of cleaning equipment, in particular to a sewage collecting device for a surface cleaning machine.

Background

The existing hand-held surface cleaning machine generally comprises a machine body, a floor brush, a liquid supply assembly and a dirt suction assembly, wherein the floor brush is provided with a cleaning piece driven by a motor and a floor scraper which is abutted against the floor, the liquid supply assembly supplies liquid to the cleaning piece to enable the cleaning piece to absorb the liquid and wet the cleaning piece to wipe the floor, the floor scraper can scrape the floor when the floor brush moves, and a dirt suction air flow formed by suction force provided by a dirt suction fan can suck dirt near a dirt suction port into a sewage bucket.

In order to enable the handheld surface cleaning machine to clean the ground in the low space such as the bed bottom, the sofa bottom and the cabinet bottom, the machine body of some existing handheld surface cleaning machines can rotate backwards for a large angle to a lying state relative to the ground brush, and the lying machine body can drive the ground brush to extend into the low space for cleaning. Because the sewage bucket is generally arranged on the machine body, when the sewage bucket is laid down backwards along with the machine body, the heights of structures such as the sewage suction fan, the sewage bucket and the pipe orifice of the sewage inlet pipe in the sewage bucket are reduced along with the inclination of the machine body, the height difference between the liquid level in the sewage bucket and the sewage suction fan is greatly reduced, under the condition that the power of the sewage suction fan is unchanged, the lift of sewage flowing into the sewage bucket from the sewage suction port on the ground brush through the sewage inlet pipe is unchanged, the distance that the sewage flowing into the sewage bucket from the sewage inlet pipe moves towards the sewage suction fan under the action of negative pressure suction force is prolonged when the sewage is laid down, and the sewage flowing into the sewage bucket can move to a position which is closer to the exhaust channel on the bucket cover. In order to enable the machine body to enter a short space, the sewage bucket is generally designed to be thinner, the included angle between the sewage bucket and the ground is smaller than 20 degrees and even is close to 0 degrees when the sewage bucket is laid down backwards along with the machine body, the liquid level in the sewage bucket and the sewage suction fan are almost at the same height, the front-back distance between the liquid level and the sewage suction fan is kept unchanged, and sewage in the bucket is closer to the inlet of an exhaust channel on the bucket cover, so that the inlet of the exhaust channel communicated with the sewage suction motor is arranged as far as possible relative to the laid sewage bucket. However, because the height difference between the inlet of the exhaust channel and the liquid level in the barrel is small, and because the dirty liquid in the barrel can shake when the user pushes and pulls the machine body back and forth, the probability that the shaky dirty liquid floods into the inlet of the exhaust channel is large, the risk of the damage of the water inflow of the dirt suction fan is high, and the stability of the working performance of the dirt suction fan is not guaranteed.

When the surface cleaning apparatus is in a lying posture, the first anti-surging portion is located below the gas-liquid separator to prevent the recovered liquid from contacting the gas-liquid separator by waves generated during the posture change of the surface cleaning apparatus. The gas-liquid separation device in the first storage part can comprise a motor and a gas-liquid separator, the motor drives the gas-liquid separator to rotate to realize gas-liquid separation, liquid is remained in the recovery storage part, and the gas is discharged after being filtered. The structure in this patent has solved the surge problem, but prevents surging the structure comparatively complicated, and complex prevents surging the structure and also has taken up more spaces of retrieving storage part, leads to retrieving the effective dirt volume of storage part less, also is unfavorable for retrieving the washing of storage part and gas-liquid separation device, in addition, because gas-liquid separation device adopts motor drive, has increased the risk that the motor was polluted by dirty liquid again, and gas-liquid separation device also can increase the cooperation degree of difficulty between retrieving storage part and the surface cleaning equipment.

In addition, there is also a structure of dividing the inner cavity of the sewage bucket into two cavities in the prior art, the upper cavity is used for containing solid dirt, the lower cavity is used for containing liquid dirt, a filter plate is arranged between the two cavities, the dirt flowing into the sewage bucket is filtered by the filter plate to enable the fixed dirt to be remained in the upper cavity, the liquid dirt flows downwards into the lower cavity, and the air flow for sucking the dirt flows upwards into the upper cavity, then flows downwards through the lower cavity and then flows to an exhaust channel communicated with the lower cavity. In this kind of structure, because exhaust passage and lower chamber direct communication, when the sewage bucket follows cleaning device's main part body and reclines, the dirt liquid in the lower chamber follows the air current flow direction exhaust passage easily, and the impaired risk of dirt suction fan feed liquor is higher like this, also is unfavorable for guaranteeing dirt suction fan's working property stability.

When the sewage collecting device 300 is mounted on the main body 200, the main body 200 is flat as a whole. It is understood that the water purifying tank 610 and the sewage collecting device 300 may be disposed at the front side or the rear side of the main body 200, or may be disposed at both sides of the main body 200, respectively, and the water purifying tank 610 may be disposed at the top of the floor brush 100. The sewage collecting device 300 is in a flat shape with the left-right width being larger than the front-back thickness, the sewage collecting device 300 is in an inclined state and a lying state along with the machine body 200, the lower end of the sewage inlet pipe 311 can be communicated with a sewage suction port, the sewage inlet pipe 311 is positioned at the front part in the barrel body 310 when the sewage collecting device 300 is in the inclined state, the sewage inlet pipe 311 is positioned at the upper part in the barrel body 310 when the sewage collecting device 300 is in the lying state, the whole machine body 200 of the surface cleaning device is flat, the machine body 200 is more beneficial to cleaning in lower spaces such as under a bed and a sofa when the machine body 200 is in the lying state, the cleaning effect under the state is ensured, the sewage does not flow back, the secondary pollution is caused to the surface to be cleaned, and the surface cleaning machine can better clean the ground which is generally free of obstacles or furniture shielding, and the like, so that the surface cleaning machine has more functions, and the cleaning requirements under different environments are met.

In this embodiment, the sewage collecting apparatus 300 may have a structure defined in any one of the first, second, third and fourth embodiments.

Other structures of the fifth embodiment are the same as those of the first embodiment, and will not be described in detail here.

In addition to the above preferred embodiments, the present utility model has other embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the utility model, which shall fall within the scope of the utility model as defined in the appended claims.
