Referring to fig. 6, in this embodiment, the air inlet pipe 500 further includes a telescopic pipe section 530 disposed between the first pipe section 510 and the second pipe section 520 and having a telescopic length, the upper end of the telescopic pipe section 530 is fixedly connected with the lower end of the second pipe section 520, and the lower end of the telescopic pipe section 530 is detachably and fixedly connected with the upper end of the first pipe section 510 through a fastening structure. It is understood that telescoping tube segment 530 may be a threaded tube. It will be appreciated that the first tube segment 510 and the second tube segment 520 may alternatively or simultaneously be telescoping tubes, and that the telescoping tube segment 530 may be omitted.
In order to avoid the situation that dust and liquid in the air flow flows into the dirt collecting fan 310 along with the air flow to cause damage to the dirt collecting fan 310, the air inlet pipe 500 is internally provided with the filter device 240. In this embodiment, the filtering device 240 is a hepa filter, and the filtering device is detachably disposed in the top end of the air inlet pipe 500. It will be appreciated that other filtering structures may be employed for the filtering device 240 to meet the filtering requirements, and of course, the filtering device 240 may be detachably mounted at other suitable positions, such as in the bottom end of the air inlet pipe 500 or in the ventilation opening 430, and the filtering device 240 may be disposed in the dust cup assembly 700 or in the power source housing 320.
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.

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.
