Description
Technical Field
The invention relates to the technical field of surface cleaning equipment, in particular to a dirty liquid recovery device and a wet and dry dust collector with the same.
Background
In daily life, the vacuum dust collection device generates air flow entering the dust collection device from the dust inlet by using the suction unit, thereby completing the working process of sucking the dust-containing air flow into the dust collection device, separating and collecting dust in the dust-containing air flow, and discharging the separated air to the outside. Vacuum cleaning devices are not generally used for sucking water, because the water flow enters the machine body and damages the suction unit. Generally, water stains and the like remained on the ground are cleaned by means of cleaning tools such as a mop, a bucket and the like, but the water absorption effect of the mop is limited, the water absorption efficiency is low, the water stains on the ground are easily caused to expand the polluted area, and the cleaning effect is poor.
In the prior art, in order to wet clean a surface to be cleaned, some specialized wet cleaning apparatuses are provided, such cleaning apparatuses comprising a cleaning liquid delivery system that delivers cleaning liquid to the surface to be cleaned, and a dirty liquid recovery system that extracts spent cleaning fluid and debris (which may include dirt, dust, dirt, soil, hair, and other debris) from the surface. The cleaning liquid delivery system generally includes a liquid supply tank for storing the cleaning liquid, a liquid spray nozzle for applying the cleaning liquid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning liquid from the liquid supply tank to the liquid spray nozzle. An agitator may be provided for agitating the cleaning fluid over the surface. The dirty liquid recovery system generally includes a dirty liquid recovery tank, a suction inlet directed toward a surface to be cleaned and in fluid communication with the dirty liquid recovery tank via a working air conduit, and a suction source in fluid communication with the working air conduit for drawing cleaning fluid from the surface to be cleaned and discharging the cleaning fluid to the dirty liquid recovery tank via the suction inlet and the working air conduit.
Of the wet cleaning apparatuses described above, a typical apparatus can be seen in chinese patent publication No. CN206434268U, which discloses a surface cleaning apparatus comprising: a housing comprising an upright handle assembly and a base mounted to the upright handle assembly and adapted to be moved over a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising: a fluid dispenser; and at least one fluid delivery channel forming part of the fluid delivery path. The fluid delivery passageway may be formed by a portion of a suction nozzle assembly on the base.
Vacuum cleaners are a common household cleaning appliance that is used to adsorb dust and debris from a dry floor, and the vacuum cleaner is somewhat frustrating when it is not possible to work on wet floors with a dirty liquid or floors that require cleaning while spraying water. The reasons for its failure are mainly: dirt liquid is easily sucked into the interior of the vacuum cleaner, and the suction motor assembly in the interior of the vacuum cleaner is usually not waterproof, so that water vapor enters the interior of the motor assembly to damage the motor so that the motor cannot work normally.
A prior chinese patent application publication No. CN108478097a discloses a cleaner capable of attaching a cleaning accessory to perform wet cleaning, and a chinese published patent application publication No. CN104768439a also discloses a moisture absorbing accessory connected to a dry cleaner to perform cleaning. The accessories in the two documents realize the expansion of the application range of the dust collector using the common dry vacuum motor, but the two documents have the defects in the aspects of suction force and reliability of gas-liquid separation.

The operation of the vacuum cleaner 100 is described below with reference to fig. 5 and 6:
when the main body 4 of the hand-held cleaner is coupled to the upright portion 20 via the hollow wand assembly 3, the inlet wand 40 is in communication with the outlet duct 224. When the main cleaner body 4 of the hand-held cleaner is operated, the upright portion 20 is inclined rearward, at this time, the upper surface 2413 and the lower surface 2414 of the float body 241 are brought down to a position close to the horizontal plane, the cleaning liquid in the cleaning liquid tank 23 is continuously supplied to the roller brush 13, and then applied to the surface to be cleaned by the rotating roller brush 13, the mixed fluid of the dirt liquid and air is rolled up by the rotating roller brush and enters the cleaning head 10 from the suction port 14 by the suction action of the suction motor 42, then flows upward through the dirt liquid inlet pipe 25 in sequence, the dirt liquid and the mixed fluid of the air flowing in from the outlet end 252 of the upper portion of the dirt liquid inlet pipe 25 collide with the inner wall surface of the upper shielding cover 26, the air and the dirt liquid after collision change the flowing direction, flow out from the liquid falling port 2201 of the lower side, the dirt liquid flows into the space 242 of the lower side under the action of gravity, and enters the dirt liquid receiving chamber 220 through the lower side of the space 242, the air flows upward from the dirt liquid receiving chamber 220 through the air outlet port 2202, and escapes into the hollow hard pipe 3 through the air outlet pipe 224, and then enters the main cleaner body 41 through the air inlet pipe 40, and finally the main cleaner body 41 is discharged. As the level of the dirty liquid in the dirty liquid housing 220 increases, the float 24 in the dirty liquid housing 220 moves upwardly, thereby driving the plug 27 to move upwardly, and when the dirty liquid housing 220 increases to the set level, the plug 27 also moves to the air outlet 2202, thereby blocking the air outlet 2202, after which the suction port 15 stops sucking the dirty liquid and air, and the user will need to empty the dirty liquid tank 22 before continuing to operate the vacuum cleaner.
In the scheme, most of the dirty liquid entering the dirty liquid accommodating chamber from the liquid falling port enters the dirty liquid accommodating chamber from the space between the buoy body and the dirty liquid inlet pipe, and the influence of air flow disturbance in the dirty liquid accommodating chamber on the buoy body is reduced by sleeving the buoy body on the outer side of the dirty liquid inlet pipe; therefore, in the dirty liquid recovery device of this structure, the flow of dirty liquid in dirty liquid accomodate indoor is more mild, and the disturbance of dirty liquid and air mixture in dirty liquid accomodate indoor is reduced, and the buoy steadily removes, and the steady flow of dirty liquid also will have reduced the dirty liquid and mix with the probability that flows in the dust catcher host computer along with the air in the air to the safe handling of vacuum motor device in the dust catcher host computer has been guaranteed.
