As shown in fig. 3-10, in some specific embodiments, surface cleaning unit 300 may include mounting frame 31, roller brush mechanism 32, cleaning solution delivery mechanism 38, and drive mechanism 39. The mounting frame 31 may be used as a mounting carrier, and the rolling brush mechanism 32, the cleaning liquid delivery mechanism 38, the driving mechanism 39, and the like may be mounted on the mounting frame 31. Accordingly, a receiving cavity for mounting each mechanism may be formed in the mounting frame 31.

As shown in fig. 2 and 6, the mounting bracket 31 may be connected to the main chassis 100 to enable connection of the surface cleaning unit 300 to the main chassis 100. Specifically, a connecting seat 33 may be connected to one side of the mounting frame 31, and may be used to connect the main chassis 100. Wherein the connection seat 33 may be connected to a rear side of the mounting bracket 31.

It will be appreciated that the mounting bracket 31 may include a front side, a rear side, a top and a bottom. During normal use of the cleaning device, the side of the mounting frame 31 away from the user may be the front side, and correspondingly, the side of the mounting frame 31 close to the user may be the rear side. The side of the mounting frame 31 close to the surface to be cleaned may be a bottom portion, and correspondingly, the side of the mounting frame 31 far from the surface to be cleaned may be a top portion.

In some embodiments, the connecting seat 33 may be rotatably connected with the mounting bracket 31, and the rotation axis of the connecting seat 33 relative to the mounting bracket 31 may be parallel to the length direction of the cleaning device. In the length direction of the cleaning device, rotating shafts are convexly arranged on two sides of the connecting seat 33 and rotatably mounted on the mounting frame 31, so that the connecting seat 33 is connected with the mounting frame 31.

Of course, in other embodiments, the connection between the connection seat 33 and the mounting frame 31 is not excluded.

As shown in fig. 6 to 8, the rolling brush mechanism 32 is detachably mounted on the mounting frame 31, and is disposed near the front side of the mounting frame 31. Specifically, the rolling brush mechanism 32 may include a rolling brush 321 and a resilient clip assembly 322. Wherein the rolling brush 321 is rotatably mounted with respect to the mounting frame 31, and the rotation axis of the rolling brush 321 may be the axis of the rolling brush 321 itself. In an embodiment, the axis of the rolling brush 321 may extend along the length direction of the cleaning device.

The elastic clamping assembly 322 is connected to one end of the rolling brush 321, and the rolling brush 321 can rotate relative to the elastic clamping assembly 322. The elastic clamping assembly 322 is detachably connected with the side wall of the corresponding side of the mounting frame 31. The end of the rolling brush 321 away from the elastic clamping component 322 is also detachably connected with the mounting frame 31. Thus, the rolling brush mechanism 32 can be integrally removed from the mounting frame 31 to replace the rolling brush mechanism 32. In an embodiment, the elastic clip element 322 can be referred to as a first elastic clip element.

Correspondingly, a mounting hole for the rolling brush 321 to pass through is formed on one side of the mounting frame 31 close to the elastic clamping component 322. During assembly, one end of the rolling brush 321, which is far away from the elastic clamping component 322, can be inserted into the mounting frame 31 from the mounting hole, and one end of the rolling brush 321, which is far away from the elastic clamping component 322, is gradually close to the opposite side of the mounting frame 31 until the rolling brush 321 and the mounting frame 31 are connected on one side, which is far away from the elastic clamping component 322. Then, the elastic clamping assembly 322 can be clamped with the side wall of the corresponding side of the mounting frame 31 to realize the assembly of the rolling brush mechanism 32.

As shown in fig. 8, the elastic clip assembly 322 may include two engaging members 3221 and an elastic member 3222. The two engaging members 3221 are similar in structure, and one engaging member 3221 is taken as an example for explanation. The engaging member 3221 may include a handheld portion 3221a and a first engaging portion 3221 b. In the width direction of the cleaning device, the first engaging portion 3221b may be connected to an end of the holding portion 3221a through a connecting plate 3221 d. In some embodiments, the handheld portion 3221a may be parallel to both the width direction and the length direction of the cleaning device, and the adapter plate 3221d may be substantially perpendicular to the handheld portion 3221 a. In the height direction of the cleaning device, the first inserting portion 3221b may be disposed on a side of the adapting plate 3221d away from the holding portion 3221 a. In the embodiment, the first engaging portions 3221b of the two engaging members 3221 are disposed oppositely. The elastic member 3222 is sandwiched between the holding portions 3221a of the two engaging members 3221, i.e., the two engaging members 3221 are disposed in a floating manner.

As shown in fig. 7, the mounting frame 31 is provided with two second insertion portions 311 corresponding to the two first insertion portions 3221 b. In some embodiments, in the height direction of the cleaning device, the first insertion portion 3221b may be a protrusion structure protruding from the adapting plate 3221d, and correspondingly, the second insertion portion 311 may be a slot structure opened at a corresponding position of the mounting frame 31. When the elastic clamping component 322 is connected to the mounting frame 31, the two first insertion portions 3221b can be respectively inserted into the corresponding second insertion portions 311, and meanwhile, the elastic member 3222 can be in a natural extension state or a compression state, so that the first insertion portions 3221b and the second insertion portions 311 can be prevented from being separated from each other at will, that is, the rolling brush mechanism 32 and the mounting frame 31 can be prevented from being separated from each other at will. In an embodiment, the elastic member 3222 may be one of a spring, a flexible block, a spring plate, and the like.

Of course, in other embodiments, the second inserting and coupling portion 311 may be a protrusion structure, and correspondingly, the first inserting and coupling portion 3221b may be a slot structure opened on the adapting block 3221 d.

As shown in fig. 6 to 8, the elastic clip assembly 322 further includes a third shell 3223 and a fourth shell 3224. The third shell 3223 is connected to one side of the fourth shell 3224 in a snap-fit manner, and forms a cavity. The holding portions 3221a of the two engaging members 3221 may be floatingly mounted in a cavity defined by the third shell 3223 and the fourth shell 3224. In some embodiments, the fourth shell 3224 is disposed at a side of the third shell 3223 away from the accommodating cavity of the mounting frame 31, and a side wall of the fourth shell 3224 away from the third shell 3223 is exposed to the external environment.

Correspondingly, a sidewall of the fourth housing 3224, which is away from the third housing 3223, is provided with two notches 3224a, which are respectively in one-to-one correspondence with the two holding portions 3221a, so that the two holding portions 3221a are exposed, and a user can conveniently touch the holding portions 3221a when disassembling and assembling the rolling brush mechanism 32. It can be understood that, in the length direction and the width direction of the cleaning device, the two holding portions 3221a may be structurally limited by the side walls of the third casing 3223 and the fourth casing 3224 at the corresponding sides, so as to prevent the holding portions 3221a from randomly swaying in the cavity surrounded by the third casing 3223 and the fourth casing 3224.

In some embodiments, a guiding plate 3221c is further connected to a side of the holding portion 3221a away from the trench 3224a, and the guiding plate 3221c may be perpendicular to the holding portion 3221 a. A guide groove 3221e is formed in a side of the guide plate 3221c away from the handheld portion 3221a, and correspondingly, a guide rail engaged with the guide groove 3221e is convexly disposed on a side wall of the third housing 3223 opposite to the guide plate 3221 c. Thus, the floating of the grip portion 3221a can be guided. It will be appreciated that the guide groove 3221e and the guide rail are disposed in a height direction of the cleaning device.

When the sewage enters the sewage tank 51 through the recovery pipe 52, the sewage flows toward the bottom of the sewage tank 51 by gravity. Therefore, the passing dirt can be filtered by the second filtering component 532, so that the solid dirt can be retained on the second filtering component 532, and the liquid dirt flows to the bottom of the sewage tank 51 to realize solid-liquid separation.

In an embodiment, second filter element 532 may be coupled to first filter element 531. Therefore, when the first filtering component 531 is detached from the sewage tank 51, the second filtering component 532 can be taken out together, so that the user can classify and treat solid pollutants and liquid pollutants conveniently, the user can be prevented from extending hands into the sewage tank 51 to detach the second filtering component 532, and accordingly, the pollution to the hands of the user can be reduced.

In some embodiments, the second filter assembly 532 may be coupled to the first filter assembly 531 via a telescoping boom 533. The telescopic frame 533 may be a folding telescopic frame, or a multi-section telescopic rod-shaped telescopic frame. In one embodiment, the length of the telescoping leg 533 may be locked by a locking member such as a pin. Accordingly, a user may adjust the distance between the first filter element 531 and the second filter element 532 as needed, that is, the depth of the second filter element 532 extending into the waste water tank 51.

In some embodiments, the first filter member 5311 can be HEPA. The second filter 5312 may be a filter screen. It can be understood that the air flow discharged after passing through the waste water tank 51 is primarily filtered by the second filter member 5312 and secondarily filtered by the first filter member 5311, thereby preventing the air flow containing more contaminants from directly passing through the first filter member 5311, and thus reducing the contamination rate of the first filter member 5311.

In some embodiments, the open end of the transfer tube 5313 with the second filter 5312 mounted thereto may extend substantially square along the height of the cleaning apparatus such that the second filter 5312 is perpendicular to the end surface of the open end of the recovery tube 52. The plane in which the first filter 5311 is located may be approximately parallel to the end surface of the open end of the recovery pipe 52. Accordingly, a side wall of the conveying pipe 5313 is bent to form a step portion 5313a, and the step portion 5313a is disposed opposite to the second end 522 of the recovery pipe 52, that is, the outlet of the recovery pipe 52 is opposite to the step portion 5313 a. The second filter 5312 can be mounted on the sidewall of the transfer tube 5313 and located away from the step portion 5313 a.

Under the blocking action of the step portion 5313a and the action of gravity, the sewage and solid sewage discharged from the recovery pipe 52 move toward the bottom of the sewage tank 51, and the airflow can continue to be discharged through the first filtering component 531. The step portion 5313a is disposed to buffer and block and divert the sewage flow, so as to prevent the sewage flow from entering the first filtering component 531. Meanwhile, the step portion 5313a is arranged to make the inner path of the air flow 5313 become tortuous, so that the air flow flowing through the air flow 5313 can be turbulent, the air flow flowing through the air flow passes through the first filter 5311 more uniformly, and the filtering effect of the first filter 5311 on the air flow is improved.

In some embodiments, the first filter assembly 531 further includes a mounting housing 5314 disposed around the circumference of the first filter member 5311, and the first filter member 5311 is fixedly mounted to the mounting housing 5314.

One end of the connection hose 700 may extend to a position of the end wall of the third mounting groove 13 away from one end of the handle unit 200, and correspond to the recovery pipe 52. So that the first end 521 of the recovery pipe 52 can communicate with the connection hose 700 when the foul water tank 51 is mounted to the third mounting groove 13. It can be understood that one end of the connection hose 700 for communicating the recovery pipe 52 can be connected with a connection seat (not shown), the recovery pipe 52 can be plugged with the connection seat, and the recovery pipe 52 and the connection seat can be plugged in a sealing manner through a sealing ring and other structural members to prevent leakage.

In one embodiment, a second elastic buckle 54 is telescopically mounted at one end of the mounting housing 5314 away from the waste water tank 51, and the second elastic buckle 54 can be telescopically arranged relative to one side of the mounting housing 5314 away from the waste water tank 51.
