Fig. 1 provides a surface cleaning apparatus 100 comprising a soil recovery system. The dirt recovery system mainly comprises a suction motor for generating suction airflow, a suction path, a recovery box 17 and a suction port, wherein the recovery box 17 and the suction port are arranged in the suction path, after the equipment is started, the suction motor generates suction airflow, dirt is recovered into the recovery box 17 from the suction port, gas-liquid separation is carried out in the recovery box 17, and sewage, impurities and the like are stored in the recovery box 17.

Referring to fig. 2 to 7, the recovery tank 17 includes a body 171 and an intake duct 172, and a storage space for storing dirt is defined in the body 171. As shown in fig. 4, the body 171 includes a bottom wall 1712 and a peripheral wall 1711 extending upward from the outer periphery of the bottom wall 1712, which together define a storage space. An air inlet conduit 172 extends through the bottom wall 1712 into the storage space in which at least part of the air inlet conduit 172 is disposed, the air inlet conduit 172 including an air inlet end 173 and an air outlet end 174, the air inlet end 173 being in fluid communication with the suction opening of the surface cleaning apparatus 100. The air outlet 174 is disposed in the storage space. In the present embodiment, the intake pipe 172 is entirely disposed in the storage space. The intake pipe 172 is integrally formed with the body 171, and the intake end 173 of the intake pipe 172 is integrally formed with the bottom wall 1712. With continued reference to fig. 2-7, the recycling bin 17 further includes a gas-liquid separator 175 disposed at the air outlet end 174 for performing gas-liquid separation on the fluid flowing out from the air outlet end 174, the gas-liquid separator 175 includes a separator body 1753 for mounting the gas-liquid separator 175 at the air inlet end 173 and a liquid guiding portion 1751 connected to the separator body 1753, the separator body 1753 may be designed to be hemispherical, the specific shape is not limited herein, the separator body 1753 includes a cavity for guiding the air flow to the liquid guiding portion 1751 for performing gas-liquid separation, and therefore, the separator body 1753 cooperates with the air inlet pipe 172 to form a lateral opening 1741.

Referring to fig. 4 and 5, the recovery tank 17 includes a use position and a pouring position, wherein the recovery tank is in the pouring position, a problem arises in that if liquid enters the inlet pipe 172 from the outlet end 174 of the inlet pipe, the liquid can only flow out of the inlet end 173 along the inlet pipe 172 unless the user intentionally rotates the recovery tank along the axis of the recovery tank 17 to pour the liquid out of the lateral opening 1741. Therefore, in order to avoid the liquid from flowing back from the inlet pipe 172, the separator body 1753 is provided with at least one through hole 1754 (refer to fig. 7) communicating with the outlet of the outlet end 174. Through-hole 1754 can be even the both ends of vapour and liquid separator 175, the tip 174 of giving vent to anger of intake pipe 172 and collection box 17 pours the mouth, like this, the user is when empting sewage, even there is liquid to get into intake pipe 172, so this part liquid also can flow from through-hole 1754, directly discharge from the department of empting of collection box 17, can avoid because of the too fast unable discharge of liquid that flows into in intake pipe 172 of speed of empting, lead to partial liquid to flow back along intake pipe 172, pollute ground or user itself.

With continued reference to fig. 4 and 5, when the recovery tank 17 is in use, the through holes 1754 are higher than the air outlets, and when the recovery tank 17 is in a dumping state, at least a part of the through holes 1754 are lower than the air outlets. In surface cleaning apparatus 100, the use of recovery tank 17 may be vertical or slightly inclined (inclined with the handle), and through-hole 1754 is higher than the air outlet, either vertically or slightly inclined. The tilted state of the recovery tank 17 means a state when the user holds the recovery tank 17 with his or her hand and pours out the contaminated water therein, that is, the recovery tank 17 must be tilted downward, that is, the pouring port of the recovery tank 17 is lower than the bottom wall 1712. When the recycling bin 17 is in a dumping state, at least part of the through holes 1754 are lower than the air outlet, and the liquid flowing into the air inlet pipe 172 can be discharged from the through holes 1754.

The recovery tank 17 also includes a cover 178 mounted at the pouring opening of the storage space, and in order to ensure the separation efficiency of the recovery tank 17 in normal use, the through hole 1754 should be closed in use to ensure that all fluid flows out through the lateral opening 1741 defined by the separator body 1753 and the air inlet tube 172, and therefore the cover 178 is provided with a first sealing structure 1781 to seal the through hole 1754 after the cover 178 is mounted to the body 171. When the recovery tank 17 is cleaned, the lid body 178 is opened, and at this time, the through holes 1754 communicate with both sides of the separator body 171, so that there is no fear of the liquid entering the intake pipe 172 flowing back when the sewage inside the recovery tank 17 is dumped. The gas-liquid separator 175 further includes a plurality of liquid deflectors 1751 provided to the separator body 1753. The liquid guide 1751 separates the gas and liquid of the contaminants. The separator body 1753 and the air inlet end 173 of the air inlet pipe 172 jointly define an opening 1741 facing the liquid diversion portion 1751, so that the air flow flowing out of the opening 1741 faces the liquid diversion portion 1751, and the separation efficiency can be effectively improved. The opening 1741 and the through hole 1754 are arranged opposite to each other, and can completely discharge liquid flowing into the air inlet pipe 172 when pouring.

In order to facilitate the taking and placing of the gas-liquid separator 175, the separator body 1753 is provided with a handle 1782, and the cover body 178 is provided with an accommodating cavity for accommodating the handle 1782. This keeps the handle 1782 from being contaminated by sewage, and further, the cover 178 is provided with a second sealing structure 1783 to seal the handle 1782 to the receiving cavity after the cover 178 is mounted to the body 171. The separator body 1753 is provided with a handle 1782, and the handle 1782 is positioned between the liquid guide portion 1751 and the through hole 1754.

In other embodiments, the recycling bin 17 further includes a filter 176 disposed on the body 171, and the filter 176 is used for solid-liquid separation when the dirt is discharged from the opening 1741 of the body 171, so as to keep at least part of the solid impurities in the storage space. The recovery box 17 is also provided with at least one liquid level detection device for detecting water level information in the storage space, the liquid level detection device (probe) generally comprises two conducting strips 179 arranged at intervals, when the two conducting strips 179 are conducted by liquid, a signal is generated, and the cleaning equipment sends out a notice to remind a user to clean the sewage tank. A filter 176 is disposed below the probe. The filter 176 is arranged below the probe, and the filter 176 can resist most splashed liquid drops, so that water drops in the recovery tank 17 are reduced from being splashed to the probe. If the water droplets form a conductive film of water near the probe, a false alarm may be generated and the user may have to clean the recovery tank 17 and the level detection device therein.

While the embodiments of the invention have been described above, it is not intended to be limited to the embodiments shown, and described, but rather to be accorded the widest scope consistent with the principles and novel features herein disclosed, and to such extent as may be readily modified by those skilled in the art, and to such extent as is not limited by the specific details shown and described herein without departing from the general concepts defined by the claims and their equivalents.
