Technical Field

The invention belongs to the technical field of household appliances, and particularly relates to a ground suction nozzle for wet-type ground cleaning equipment.

Background

Conventional wet floor cleaning devices, such as floor washers, typically utilize a suction nozzle to clean and soil the floor to be cleaned. In the prior art, such equipment usually needs the user to repeatedly and continuously move the suction nozzle back and forth to suck up dirty liquid on the ground as far as possible, but because the suction is limited and the structure of the suction nozzle is arranged, the small particle liquid remained on the ground is difficult to suck up, so that the ground drying effect is poor after cleaning, and the residual water stain can easily cause secondary pollution.

Chinese patent publication No. CN108652519A discloses a "floor brush machine cleaning and dust collecting machine", which is operated by pumping clean water into a clean water tank through a water pump and spraying the clean water into a rolling brush cavity through a water spray nozzle, so as to wet a rolling brush and facilitate the rolling brush to scrub the ground. For the convenience of clearing away the foul solution on ground, on this washing dust catcher's scrubbing brush, set up preceding, two sets of wind channels in back and the preceding, the back dust blocking piece that correspond and accomplish the soil pick-up work, specifically do: when the floor brush moves forwards, the front dust-blocking piece is opened, large-particle dust and wastewater enter the forward air inlet and the rolling brush cavity from the front dust-blocking piece, and the rear dust-blocking piece vertically scrapes the ground and blocks the dust and wastewater which are not cleaned in time in the floor brush; when the scrubbing brush moves backwards, the rear dust-blocking piece is opened, large-particle dust and wastewater enter the rear air inlet and the rolling brush cavity from the rear air inlet, and the front dust-blocking piece vertically scrapes the ground and blocks the dust and wastewater inside the scrubbing brush, which are not cleaned in time, inside the scrubbing brush. In a word, this washs dust absorption scrubbing brush and washs dust catcher through the setting of two air intakes, double air duct and wind channel spacer to cooperation front and back fender dirt piece, make the even balance of flow, the suction of front and back air intake. The front air inlet, the rear air inlet and the suction capacity are not distinguished, the floor brush can only ensure that the same cleaning and dirt absorbing functions can be realized in the forward and backward moving process of the floor brush, and small-particle liquid remained on the ground cannot be thoroughly removed.

One "surface cleaning apparatus" disclosed in publication No. CN206434268U defines a suction nozzle in its brush roll chamber in fluid communication with the foot conduit and is configured to draw liquid and debris from the brush roll and surface to be cleaned. The suction nozzle defines a dirty air inlet through a working air path or a recovery path of the vacuum cleaner. The suction nozzle is further fluidly connected to the canister assembly by a foot conduit and a flexible conduit hose; the rear scraping blade is arranged at the rear part of the brush roller, but after the brush roller cleans and sucks dirt on the ground to be cleaned, a small part of sewage still flows to the rear scraping blade, and then the scraping blade only plays a role in scraping the ground to be cleaned, and the dirt sucking capability is omitted, so that water stain can still be remained on the ground to be cleaned, and the use of a user on the ground is influenced.
