The stored recovered liquid creates waves that may enter the gas-liquid separator 422 if the waves are not suppressed. Therefore, the wave can be blocked by the baffle of the second anti-surge part 434, and the liquid can also be made to flow through the liquid through holes provided on the baffle. In addition, at least one (for example, three) end surfaces of the second surge preventing part 434 may fit inside the recovery storage part 400 .

In addition, the opening area occupied by the filter part 433 can be set to be greater than or equal to the opening area occupied by one or more liquid through holes provided in the second surge preventing part 434 (for example, the total opening occupied by the two filter parts 433 ) The area can be set to be greater than or equal to the total opening area occupied by the liquid through holes), so that at least when the surface cleaning device is in a parallel attitude, the air is mainly fed into the gas-liquid separator 422 from the position of the filter portion 434 . This prevents the liquid from reaching the gas-liquid separator 422 from the lower part of the first surge-preventing part 435 through the first anti-surge part 435 when viewed in a parallel posture, which affects the gas-liquid separation effect of the gas-liquid separator 422 .

The first anti-surge portion 435 is disposed opposite to the gas-liquid separator 422, and optionally, the central axis of the first anti-surge portion 435 and the central axis of the gas-liquid separator 422 are parallel to or coincide with each other, which is preferred in the present disclosure The two central axes of the ground coincide with each other (as shown in Figure 20). The central axis of the gas-liquid separator 422 may be the axis where the center of its driving shaft is located, and the central axis of the first anti-surge portion 435 may be the central axis of the hollow portion of the first anti-surge portion 435 mentioned below.

The transition portion 4352 is located between the edge portion 4351 and the hollow portion 4353 . From the plane in which the edge portion 4351 is located, the transition portion 4352 extends obliquely to the hollow portion 4353 , such that the transition portion forms a slope between the edge portion 4351 and the hollow portion 4353 . When the surface cleaning apparatus installed with the recovery storage part 400 is in a parallel attitude, the inclination direction of the transition part 4352 is a downward direction, and the inclination direction of the transition part 4352 is a direction away from the gas-liquid separator 422 .

In this way, the liquid in the space where the gas-liquid separator 422 is located can enter the first anti-surge portion 435 and slide down along the transition portion 4352 . Furthermore, due to the shape setting of the first surge preventing portion 435, when the surface cleaning apparatus is transformed from the upright posture to the inclined use posture, or the parallel posture (lying-flat posture), or from the inclined use posture to the parallel posture, due to the surface cleaning When the angle of the equipment changes, the first anti-surge part 435 can also offset the waves generated by the angle change, so as to prevent the liquid from entering the gas-liquid separator 422 due to the waves.

In addition, when the surface cleaning apparatus (returning the storage part 400 accordingly) performs a posture change between the inclined use posture and the parallel posture, a wave may also be formed between the first cavity and the fourth cavity, and the wave may The open end of the recovery conduit 440 and possibly even the gas-liquid separator 422 may be affected. In order to avoid these effects, the bottom wall 4311 can be used as a third anti-surge part, wherein when the waves contact the bottom wall 4311, the waves can be counteracted by the avoidance of the bottom wall 4311, and the first liquid conduction hole of the bottom wall 4311 can be used to achieve the first Fluid communication between the cavity and the fourth cavity.
