Referring to fig. 1, 2 and 7, the main body 220 has an upright state and a lying state, and when the main body 220 is in the upright state, the main body 220 and the hand-held portion 210 are maintained in a relatively fixed state by a snap structure, and at this time, the main body 220 and the hand-held portion 210 are simultaneously rotated forward or backward within a certain angle range. Referring to fig. 1, when the main body 220 is in an upright state and the main body 220 and the hand-held portion 210 are simultaneously rotated forward to a front limit position, the main body 220 is in a substantially vertical state. Referring to fig. 2, when the main body 220 is in an upright state and the main body 220 and the hand-held portion 210 are simultaneously rotated backward to a rear limit position, the main body 220 is inclined at an angle with respect to the surface to be cleaned. It will be appreciated that when the main body 220 and the hand-held portion 210 are rotated forward synchronously to the front limit position, the main body 220 may be tilted forward at an angle with respect to the vertical. It will be appreciated that the inclination angle α of the main body 220 with respect to the surface to be cleaned may be set to be reasonably large such as 60 °, 57 °, 55 °,52 °,50 °,47 °,45 ° and the like when the main body 220 is rotated rearward to the rear limit position with the hand-held portion 210 in the upright state.

Referring to fig. 7, when a user needs to clean a surface to be cleaned in a low area such as a bed bottom, a cabinet bottom, a sofa bottom, etc., the button 211 is pressed to disengage the buckle 212 from the clamping groove on the clamping block 221, at this time, the main body 220 and the hand-held portion 210 are in a relatively rotatable state, the main body 220 can continue to rotate downwards from the rear limit position in the upright state and can rotate to be parallel to the surface to be cleaned, and the position between the rear limit position in the upright state and the position parallel to the surface to be cleaned of the main body 220 is a lying state. When the main body 220 is in the lying state, the hand-held part 210 can still be in the standing state, and the sewage collecting fan 310 is higher than the sewage bucket 410, so that the situation that the sewage in the sewage bucket 410 flows into the sewage collecting fan 310 to damage the sewage collecting fan 310 when the main body 220 is lying down is avoided. It is to be understood that the main body 220 may be inclined with respect to the surface to be cleaned when being rotated downward to the limit position in the lying state, and the inclination angle α of the main body 220 with respect to the inclined surface to be cleaned may be set to be a reasonable magnitude such as 45 °, 40 °, 35 °,30 °, 25 °,20 °,15 °,10 °,7 °,5 °,3 °, 0 °.

In order to avoid the user from directly rotating backward to the main body 220 to lie down, a limiting structure can be arranged between the hand-held part 210 and the main body 220, when the main body 220 rotates backward to the rear limit position in the standing state, the main body 220 cannot rotate backward again under the limiting action of the limiting structure, the limiting structure is unlocked while the buckle structure is unlocked, and the main body 220 can rotate backward.

In operation of the device, the liquid supply assembly 600 supplies liquid to the cleaning member 170 to enable the cleaning member 170 to absorb the liquid and wet, the driving assembly drives the cleaning member 170 to rotate so that the cleaning member 170 wipes the surface to be cleaned, the scraping plate 150 scrapes the rotating cleaning member 170, the ground scraper 160 scrapes the surface to be cleaned when the ground brush 100 moves, the dirt collecting fan 310 provides suction force to form dirt collecting air flow flowing from the dirt suction opening 110, the dirt collecting air flow flows into the dirt bucket 410 through the dirt suction channel 230 and the dirt inlet 420, the dirt follows the dirt collecting air flow to flow into the dirt bucket 410 and is collected in the dirt bucket 410, the dirt collecting air flow flowing through the dirt bucket 410 flows out of the dirt bucket 410 from the air inlet pipe 500 to the dust cup assembly 700, flows to the dirt collecting fan 310 after flowing through the dust cup assembly 700, and finally the dirt collecting air flow flowing through the dirt collecting fan 310 is discharged out of the power source housing 320.

The sewage bucket 410 is provided with a highest water level, a detection electrode for detecting the water level is arranged in the sewage bucket 410, and when the water level in the sewage bucket 410 reaches the highest water level, the detection electrode is conducted through liquid in the sewage bucket 410, and the sewage collecting fan 310 stops working. When the main body 220 is in a lying state, the bottom surfaces of the sewage inlet pipe 450 and the ventilating pipe 460 are higher than the highest water level of the sewage bucket 410, so that the sewage collecting fan 310 can provide suction force to smoothly form sewage collecting air flow flowing through the sewage bucket 410, and the sewage collecting function can be smoothly performed. It is understood that the specific structure of the detection electrode may refer to the prior art, and will not be described herein.

Referring to fig. 8, the surface cleaning apparatus has a resting state in which the power source assembly 300, dirt cup assembly 700, and hand-held portion 210 are sagged relative to the main body portion 220.

It will be appreciated that the fresh water tank 610 may be provided on the front side of the main body 220 or on the rear side of the main body 220.

At this time, the sewage inlet pipe 450 extending from the sewage inlet 420 into the sewage tank 410 is provided in the sewage tank 410, and the sewage outlet 470 is provided at the other end of the sewage inlet pipe 450 to communicate the sewage suction passage 230 with the sewage tank 410, and the height of the sewage inlet pipe 450 in the horizontal lying state is higher than the highest water level which can be accommodated when the sewage tank 410 is in the horizontal lying state, so that the sewage outlet 470 is always located above the liquid level in the sewage tank 410, thereby avoiding the sewage from flowing backward. Preferably, the sewage inlet pipe 450 is bent in a direction away from the ventilation opening 430, and when the sewage bucket 410 is in a lying state with the main body 220, the bent section of the sewage inlet pipe 450 is higher than the highest water level in the sewage bucket 410, so that the sewage outlet 470 can be higher than the highest water level in the sewage bucket 410. When the sewage bucket 410 is in an upright state with the main body 220, the bent section of the sewage inlet pipe 450 is also higher than the highest water level in the sewage bucket 410 so that the sewage outlet 470 can be higher than the highest water level in the sewage bucket 410. As one way of realising, the sewage inlet pipe 450 extends a distance towards the bottom of the sewage tank 410, with the sewage outlet 470 towards the bottom of the sewage tank 410.

The sewage bucket 410 is further provided with a vent 430 communicating with the air inlet duct 500, and the sewage bucket 410 communicates with the sewage collecting fan 310 through the vent 430 and the air inlet duct 500. As a preferred embodiment of the present embodiment, the vent 430 is provided at an upper portion of the rear sidewall 412 and higher than the sewage inlet pipe 450, and the ventilating pipe 460 extending from the rear sidewall 412 toward the front sidewall 411 is provided in the sewage bucket 410 corresponding to the vent 430.

When the sewage bucket 410 is in a lying state along with the main body 220, the bent section of the sewage inlet pipe 450 and the top surface of the ventilating pipe 460 are higher than the highest water level in the sewage bucket 410, so that the liquid in the sewage bucket 410 is prevented from flowing out from the sewage inlet 420 or the ventilating opening 430.

As an alternative to this embodiment, the vent 430 is provided on the top wall of the wastewater tank 410 and is provided near the front side wall 411 of the wastewater tank 410.
