The lower bottom edge of the separator 372 connected with the isolation part 3712 of the baffle 371 is in clearance with the inner side wall 3202 of the second recovery cavity 320, two side edges of the separator 372 are in sealing fit with the inner side wall 3202 of the second recovery cavity 320, and the upper top edge of the separator 372 can be inclined to be in sealing fit with the inner side wall or also in clearance with the inner side wall and in sealing and pressing fit with the pressing plate 384 at the top opening 3203 of the second recovery cavity 320;

the above-described arrangement of the partition 372 serves to prevent the sewage in the sewage storage portion 322 from flowing backward from the partition 372 into the gas-liquid separation portion 321. That is, the dirt storing portion 322 located at the other side of the flow guiding device 370 in the second recovery chamber 320 is formed by at least the space surrounded by the flow guiding plate 371, the bottom wall 3201 of the second recovery chamber 320, the partition 372, and the inner side wall 3202 of the second recovery chamber 320, and the dirt storing portion 322 includes not only the space of the second recovery chamber 320 located at the lower part of the flow guiding plate 371, but also the space of the second recovery chamber 320 located at the upper part of the flow guiding plate 371 and located between the partition 372 and the inner side wall 3202 of the second recovery chamber 320.

The partition 372 includes a first side plate 3721, an intermediate connecting plate 3722 and a second side plate 3723 extending vertically along the partition 3712 towards the gas-liquid separation portion 321, the intermediate connecting plate 3722 is disposed between the first side plate 3721 and the second side plate 3723, the side edges of the first side plate 3721 and the second side plate 3723 are respectively in sealing fit with the inner side wall 3202 of the second recovery chamber 320, the intermediate connecting plate 3722 is disposed at a distance H from the inner side wall 3202 of the second recovery chamber 320, and the intermediate connecting plate 3722 is matched with the inner side wall 3202 of the second recovery chamber 320 in shape, in this embodiment, all of the shape of circular arcs disposed concentrically, that is, a tile-like annular column space is formed between the partition 372 and the second inner side wall 3202, and the diameter ratio of the distance H to the second recovery chamber is preferably greater than or equal to 1:6.

The lower space of the first recovery chamber 310 may be in fluid communication with the dirt storage portion 322 of the second recovery chamber 320, the lower space of the first recovery chamber 310 also being provided as a dirt storage portion of the recovery tank to further increase the actual dirt storage capacity of the recovery tank 300.

When the user starts to use the surface cleaning apparatus, the main body 100 is gradually inclined when in use, and since the lower bottom edge of the partition 372 is disposed at a distance from the inner sidewall 3202 of the second recovery chamber 320, part of the sewage in the sewage storage portion 322 below the baffle 371 can flow from the distance to the annular column space formed between the partition 372 and the second inner sidewall and temporarily store in the lower space of the first recovery chamber 310, so that the risk that the sewage shakes easily to flow back to the gas-liquid separation portion 321 from the water outlet on the side of the communicating portion 3711 of the baffle 371 during use when the inclination angle is too large is reduced.

Therefore, the surface cleaning apparatus with the recycling bin 300 can not only greatly incline the machine body 100 and even level the machine body for use, but also prevent water from entering the power device, namely the motor, so that the use scene of a user is greatly enriched, and the cleaning of the floor in low space such as bed bottom, sofa bottom and the like is possible.

As shown in fig. 17, a buffer structure 323 is disposed in the dirt storage portion 322 of the second recovery chamber 320 near the water outlet 37112, so as to prevent the dirty water in the dirt storage portion 322 of the recovery tank from swaying back and forth to splash and move along the water outlet 37112 of the inner sidewall or deflector 371 toward the upper gas-liquid separation portion 321 when the user pushes and pulls the surface cleaning apparatus back and forth.

The buffer structure 323 may be disposed on an inner sidewall of the dirt storage portion 322, and optionally, the buffer structure 323 includes at least a splash-proof portion 3231 extending radially from the inner sidewall to the second recovery chamber 320, and the splash-proof portion 3231 may be disposed in a planar shape or a curved shape or a shaped form composed of a plurality of planar or curved surfaces, and may extend substantially perpendicularly to the inner sidewall in a radial direction or extend obliquely in a radial direction and in a bottom wall direction, so long as it can inhibit the splashing of the sewage impinging on the inner sidewall.

The buffer structure 323 further includes a guide portion 3232 connected to the splash guard portion 3231 and extending from the splash guard portion 3231 in the bottom wall direction, and the guide portion 3232 is configured to guide the contaminated water away from the water outlet 37112 and toward the bottom wall of the second recovery chamber 320. The guide portion 3232 of the buffer structure 323 is connected to the communication portion 3711 of the flow guiding device 370, and an end portion of the guide portion 3232 is closer to the bottom wall of the second recovery chamber than the communication portion 3711.

More preferably, the splash-proof portion 3231 is configured to extend obliquely in the radial direction toward the bottom wall and is configured as an arc plate protruding toward the water outlet, so that the flow can be guided by the coanda effect of the protrusion and the sewage can be prevented from splashing and overflowing upward from the water outlet by the groove facing the bottom wall.

As shown in fig. 20 to 27, the recycling bin 300 further includes an upper cover assembly 380, the top of the recycling bin 300 has an opening for installing the upper cover assembly 380, and the cross section of the top opening end of the recycling bin is one of a circle, a racetrack ring shape, a double ring shape (formed by combining two basic circles of the first recycling bin 310 and the second recycling bin 320), or a rectangle, and the cross section of the upper cover assembly 380 is also one of a circle, a racetrack ring shape, a double ring shape, or a rectangle.

In this embodiment, the upper cover assembly 380 includes a cover 381 and is detachably installed at the top opening 301 of the recovery tub 300; the upper end of the cover 381 is a race track-like shape having a slanted opening, the upper end of the cover 381 has a contour matching with that of the recycling bin 300, and the lower end includes an annular mounting portion 385, and the annular mounting portion 385 is matched with the cross-sectional shape of the top horizontal opening or the slanted opening of the recycling bin 300.

The annular mounting portion 385 of the upper cap assembly 380 and the top opening 301 of the recovery tank 300 may be connected by screw connection or by interference fit. In order to improve the assembly and disassembly efficiency of the upper cover assembly 380 and the top opening 301 of the recycling bin, an annular mounting cavity 302 which is arranged around the opening and can be matched with the annular mounting part 385 is arranged on the inner wall of the top opening 301 of the recycling bin 300, when the upper cover assembly 380 is assembled on the recycling bin 300, the annular mounting part 385 on the upper cover assembly 380 is positioned at the annular mounting cavity 302 of the recycling bin 300 by pressing the upper cover assembly 380, and the upper cover assembly 380 is clamped on the recycling bin 300 by interference fit between the annular mounting part 385 on the upper cover assembly 380 and the annular mounting cavity 302 on the recycling bin 300.

In order to improve the connection sealability between the upper cover assembly 380 and the recovery tub 300, a first sealing ring 3851 is provided between the upper cover assembly 380 and the top opening 301 of the recovery tub 300. Specifically, the first sealing ring 3851 is disposed in a region between the annular mounting portion 385 on the upper cover assembly 380 and the annular mounting cavity 302 on the recovery tank 300, and may be disposed on either one of the two.

The bottom of the annular mounting portion 385 of the cover body 381 is provided with a pressing plate 384 having a cross-sectional shape matching that of the annular mounting chamber 302, and the pressing plate 384 is disposed above the top opening 3103 of the first recovery chamber 310 and the top opening 3203 of the second recovery chamber 320 in a pressing and sealing manner. The pressure plate 384 is provided with an upper cover air inlet 386 and a guide cover 387 facing the inside of the second recovery chamber 320 corresponding to the position of the second recovery chamber 320, the guide cover 387 being provided directly above the second inlet duct 362 and covering the second air outlet 3621 of the second inlet duct 362 inside thereof.

In the case of the pod 387 shown in fig. 23, the pod 387 has a first side 3871 and a second side 3872 that extend in a direction away from the cover 381 and are disposed opposite to each other, the first side 3871 is disposed on a side of the pod 387 near the upper cover air inlet 386, the second side 3872 is disposed on a side of the pod 387 away from the upper cover air inlet 386, and an end of the first side 3871 is farther from the cover 381 than an end of the second side 3872.

The pod 387 is configured as described above to facilitate the flow of fluid from the second outlet 3621 of the second inlet conduit 362 to the second side 3872 on a side remote from the upper cover inlet 386 and to facilitate separation of the contaminated water therein from the gas. The air escaping from the direction of the second side 3872 is guided by the air guide cover 387 and the air guide device 370 to wind to the first side 38713871 side of the air guide cover 387, and enters the upper cover assembly 380 through the upper cover air inlet 386 for filtering and discharging.

24-25, the pod 387 has a first side 3871 and a second side 3872 extending away from the cover 381, the first side 3871 being disposed on a side of the pod 387 adjacent the upper cover air inlet 386, the second side 3872 being connected to the first side 3871 and forming the other side of the pod 387; the end of the second side 3872 is recessed with a plurality of notches to facilitate escape of gas. Specifically, after the water vapor mixture is discharged through the second air outlet 3621 of the second inlet pipeline, most of the water mist and water drops are collected together after being decelerated due to the wall attaching characteristic and flow downwards along the inner wall of the air guide cover 387 under the influence of gravity, and because the top end of the notch arranged on the second side wall 3872 is higher than the bottom end of the second side wall 3872, part of the gas can be separated from the liquid from the notch at the first time, and the gas-liquid separation effect is improved.

The pressure plate 384 is also in sealing engagement with the top of the first side plate 3721 intermediate web 3722 and the second side plate 3723 of the divider 372 when the pressure plate 384 is sealingly disposed over the top opening 3103 of the first recovery chamber 310 and the top opening 3203 of the second recovery chamber 320, thereby completely sealing the top of the tile-like annular column-like space formed between the divider 372 and the second inner side wall.

That is, the dirt storing portion 322 of the second recovery chamber 320 located at the other side of the flow guiding device 370 is formed by the space surrounded by the flow guiding plate 371, the bottom wall 3201 of the second recovery chamber 320, the partition 372, the inner sidewall 3202 of the second recovery chamber 320, and the pressing plate 384 of the upper cover assembly 380, and includes not only the space of the second recovery chamber 320 located at the lower part of the flow guiding plate 371, but also the space of the second recovery chamber 320 located at the upper part of the flow guiding plate 371 between the partition 372, the inner sidewall 3202 of the second recovery chamber 320, and the pressing plate 384.

The upper cover assembly 380 further comprises a filtering hepa 382 arranged in the cover body 381, an upper cover air outlet 383 communicated with the power device is arranged at the top of the cover body 381, and a filtering hepa 382 mounting groove is concavely arranged on the upper cover air outlet 383 and used for mounting the filtering hepa 382 in the cover body 381 from the upper cover air outlet 383.

The prior art upper cover assembly 380 is generally configured to match the shape of the recycling bin 300 (corresponding to the second recycling cavity 320), and the cross-sectional area of the filtered sea cucumber 382 in the upper cover assembly 380 is generally configured to be substantially uniform with the cross-sectional area of the upper cover air inlet 386, and the cross-sectional area of the filtered sea cucumber 382 is too small due to the limited cross-sectional area of the upper cover air inlet 386, which often results in blockage failure.

In order to effectively reduce clogging and prolong the use time of the user, the cross-sectional areas of the filter sea paper 382 and the upper cover air outlet 383 are both set to be substantially identical to the profile cross-sectional area of the upper end of the cover body 381, that is, the cross-sectional area of the filter sea paper 382 is set to be substantially identical to the cross-sectional area of the top opening 301 of the recovery tub 300, which is much larger than the cross-sectional area of the upper cover air inlet 386, which is substantially equivalent to the sum of the cross-sectional areas of the top openings 3203 of the first recovery chamber 310 and the second recovery chamber 320.

The bottom of the filter sea cucumber 382 is disposed in a gap with the upper cover air inlet 386 (as shown in fig. 27), thereby ensuring that the air sucked into the cover 381 from the upper cover air inlet 386 can be filtered not only by the portion of the filter sea cucumber 382 near the air inlet but also by the portion of the filter sea cucumber 382 near the air inlet.

Similarly, the air inlet of the power device is also arranged in a clearance with the filtering sea paper 382, so that the whole filtering sea paper 382 can work normally, and the effective filtering sectional area of the filtering sea paper 382 is greatly improved.

A second sealing ring 3821 is arranged at the air outlet 383 of the upper cover. Specifically, the second seal 3821 may be disposed around the top of the filter sea paper 382 to ensure a sealing connection between the power device and the upper cover assembly 380.

The power device extracts the air in the recovery barrel 300 through the filtering of the HEPA 382, so that negative pressure is formed in the recovery barrel 300, sewage in the surface cleaning device flows into the recovery barrel 300 through the first inlet pipeline 331 under the action of the negative pressure, and the phenomenon that solid garbage blocks the power device can be reduced by the upper cover assembly 380.

Notably, the bottom wall 3101 and the top opening 3103 of the first recovery cavity 310, the bottom wall 3201 and the top opening 3203 of the second recovery cavity 320 respectively form part of the bottom wall and the top opening 301 of the recovery bucket 300, i.e. the height of the first recovery cavity 310 and the second recovery cavity 320 is arranged substantially identical to the height of the recovery bucket 300. In some prior art, although there are a so-called "first recovery chamber 310" and a so-called "second recovery chamber 320", it is actually that a plurality of separation areas are disposed in a single recovery chamber, and the plurality of separation areas can achieve the effect of solid-liquid separation and gas-liquid separation, but the heights of the plurality of separation areas together form the height of the recovery tank 300, which greatly sacrifices the space of the gas-liquid separation portion and the dirt storage portion 322, that is, the separation effect and the dirt storage space are greatly weakened; the scheme of the embodiment realizes the solid-liquid separation storage in the true sense on the premise of not reducing the gas-liquid separation effect and the dirt storage space.

The working principle and procedure of the surface cleaning apparatus, in particular the recovery tank 300, is described below by means of different usage scenarios.

Using scenario 1:

when the surface cleaning apparatus is operated in a normal tilted posture, the deflector 371 of the deflector 370 is tilted with respect to the surface to be cleaned, and the communicating portion 3711 thereof is located closer to the surface to be cleaned than the separating portion 3712.

The power device rotates, negative pressure is generated at the suction nozzle 210 in fluid communication with the power device, solid garbage and/or liquid garbage on the surface to be cleaned is sucked into the fluid recovery system of the surface cleaning device through the suction nozzle 210 under the action of the negative pressure, fluid flows into the first recovery cavity 310 from the first air inlet 3104 of the bottom wall 3102 of the first recovery cavity 310 through the first inlet pipeline 331, solid-liquid separation is realized by the filter 350 arranged in the first recovery cavity 310, separated solid garbage is collected by the filter 350, separated liquid garbage flows into the second recovery cavity 320 through the first air outlet 3105 of the inner side wall 3102 of the first recovery cavity along with the dirty air, the fluid is subjected to gas-liquid separation in the gas-liquid separation part 321 of the second recovery cavity 320, separated liquid is guided by the guide plate 371 and discharged to the lower dirt storage part 322 along the water outlet of the guide plate, and the separated gas is discharged after being covered by the power device.

The above surface cleaning apparatus can truly realize separate recycling and storage of solid garbage and liquid garbage due to the unique structure of the recycling bin 300, so as to solve the problem of easy mold and odor generation caused by long-time cleaning of the recycling bin 300, and a user can clean the solid garbage or the liquid garbage in the first or the second recycling cavity 320 independently as required.

Using scenario 2:

when the user starts to use the surface cleaning apparatus, the body 100 is gradually inclined by a larger inclination angle even approaching a horizontal level when in use, since the lower bottom edge of the partition 372 of the second recovery chamber 320 is spaced from the inner sidewall 3202 of the second recovery chamber 320, part of the sewage storage portion 322 under the baffle 371 can flow from the space to the annular column space formed between the partition 372 and the second inner sidewall and temporarily store in the lower space of the first recovery chamber 310, so that the risk that the sewage shakes easily to flow back from the water outlet on the side of the communicating portion 3711 of the baffle 371 to the gas-liquid separation portion 321 occurs during use when the inclination angle is too large.

When the surface cleaning apparatus is in a greatly inclined posture or even works nearly horizontally, the baffle 371 of the baffle 370 is inclined with respect to the surface to be cleaned, the isolation part 3712 thereof is located at a position closer to the surface to be cleaned than the communication part 3711, at this time, the sewage separated from the upper part of the baffle 371 cannot be automatically discharged from the water outlet by self weight, and the sewage is discharged to the sewage storage part 322 through the check valve 37122 provided at the isolation part 3712.

Therefore, the surface cleaning apparatus with the recycling bin 300 not only can greatly incline the machine body 100 when in use, but also can be used even flatly, and the motor in the power device is not easy to generate water inflow and other problems, so that the use scene of a user is greatly enriched, and the cleaning of the ground in low space such as the bed bottom, the sofa bottom and the like is possible.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
