It is apparent that the surface cleaning apparatus 100 of the present embodiment is a hand-held cleaning apparatus, which can perform dry cleaning or wet cleaning according to different surfaces to be cleaned.

Referring to fig. 2 to 4, fig. 2 is a plan view showing a cleaning apparatus of a surface cleaning device in the present embodiment, fig. 3 is an exploded view showing a cleaning module of the cleaning apparatus of fig. 2 in a flipped state, and fig. 4 is a cross-sectional view showing the cleaning apparatus of fig. 2, the cleaning apparatus 200 including a base 210, a cleaning module 220, and a cover structure 230. The cleaning module 220 is disposed on the base 210, and is used for cleaning a surface to be cleaned. Obviously, the base 210 is a mounting structure for the cleaning module 220. The cover structure 230 is detachably coupled to the base 210 and located on the cleaning module 220, so that the cleaning module 220 is located between the base 210 and the cover structure 230.

The cleaning module 220 includes a cleaning module 240 and a flipping structure 250. The cleaning module 240 includes a driving structure 241 and a roller brush 242 to clean a surface to be cleaned. The driving structure 241 is connected to one end of the rolling brush 242, and is used for driving the rolling brush 242 to rotate. The other end of the roller brush 242 is mounted on the base 210 and rotatably disposed with respect to the base 210, so that the roller brush 242 can sweep the surface to be cleaned by rotating itself. The turning structure 250 is mounted on the base 210 (mounting structure) and connected to the driving structure 241, and the turning structure 250 is used for turning the cleaning module 240, so that the other end of the rolling brush 242 is turned in a direction away from or close to the surface, that is, the rolling brush 242 can be turned up and down relative to the base 210 or the surface to be cleaned by the turning structure 250.

When cleaning or replacing the rolling brush 242, the cover body structure 230 is detached firstly to expose the cleaning module 220, and as the cleaning module 240 of the cleaning module 220 is connected with the overturning structure 250, the cleaning module 240 can be overturned upwards through the overturning structure 250, so that the other end of the rolling brush 242 can be upwards rotated to be lifted and suspended, the rolling brush 242 can be conveniently and manually taken down from the driving structure 241 by a user, dirt on hands, which is attached to the rolling brush 242, can be reduced or avoided, and the rolling brush 242 can be quickly and easily detached; when the rolling brush 242 is installed, the rolling brush 242 can be more easily and conveniently installed on the driving structure 241 due to the fact that the position of the cleaning module 240 after being turned over is more free relative to the working position thereof, and the installation efficiency of the rolling brush 242 is improved. After the installation of the roller brush 242 is completed, the cleaning module 240 is pushed to rotate downward, so that the other end of the roller brush 242 rotates downward onto the base 210. Therefore, through the turning structure 250, the rolling brush 242 can be detached and installed more conveniently, the disassembly and assembly efficiency of the rolling brush 242 is greatly improved, the condition that hands are stained with dirt when the rolling brush 242 is taken down is effectively reduced or avoided, the user experience is improved, and particularly the rolling brush is detached under the heavy dirt scene, so that the rolling brush has very obvious user experience advantages.

In this embodiment, the main body 310 includes a sewage tank (not numbered), a negative pressure source (not numbered) and a clean water tank (not numbered), and the sewage tank, the negative pressure source and the clean water tank may be sequentially arranged from bottom to top or laid out in other manners, and may also be that the sewage tank and the clean water tank may be arranged in the same accommodating space, and clean water and sewage may be split by the film layer. The inner surface of the cover structure 230 is provided with a water outlet, and the clean water tank applies clean water in the tank body to the rolling brush 242 through the water outlet of the cover structure 230 by a water pump. The sump communicates through a passage to the roller brush 242 for collecting dirt, such as garbage, hair, debris, sewage, etc. The negative pressure source is used for generating negative pressure, and dirt on the surface to be cleaned is sucked into the channel through the rolling brush 242 and finally enters the sewage tank. It will be appreciated that in other embodiments, the base 210 may be provided with a clean water tank and/or a dirty water tank, rather than a clean water tank and/or a dirty water tank on the fuselage 300.

The overturning structure 250 includes a connecting portion 251 and a pivoting portion 252. The connection portion 251 is connected to the driving structure 241, and the pivot portion 252 is disposed at one end of the connection portion 251, where the pivot portion 252 is pivotally connected to the base 210 (mounting structure), and is rotatably disposed relative to the base 210. Because the pivot portion 252 is rotatably connected to the base 210 (mounting structure), when the turnover structure 250 is turned over, the pivot portion 252 and the connecting portion 251 thereof rotate relative to the base 210, and the linkage driving structure 241 and the roller brush 242 are turned over, it is obvious that the turnover structure 250 has a simple structure, is easy to turn over, and is beneficial to cost control.

In order to keep the turned cleaning module 240 in a turned state, the roller brush 242 is prevented from falling under the action of gravity, the pivot portion 252 is a damping shaft, the base 210 (mounting structure) is provided with a corresponding shaft hole, the damping shaft is inserted into the shaft hole, and rotational friction exists between the damping shaft and the shaft hole, the rotational friction is enough to keep the cleaning module 240 to stay at a required turning angle, so that the roller brush 242 is convenient to detach and mount, and the disassembly and assembly efficiency of the roller brush 242 is further improved. It is understood that in other embodiments, the pivot portion 252 may be a shaft hole and open at one end of the connecting portion 251. The base 210 is provided with a corresponding shaft body, and the shaft body is inserted into the shaft hole, so that the pivot connection between the turnover structure 250 and the base 210 (the mounting structure) is realized. Further, the shaft body of the base 210 may be a damping shaft.

In this embodiment, the connection portion 251 has a sheet-like or block-like structure, and an inner side surface thereof is connected to the driving structure 241. The base 210 is also provided with a mounting sidewall 211, and the mounting sidewall 211 is disposed opposite to the connection part 251. The other end of the roller brush 242 is rotatably provided on the mounting sidewall 211 such that the roller brush 242 is positioned between the connection portion 251 and the mounting sidewall 211. Because the connecting part 251 is in a sheet-shaped structure or a block-shaped structure, a user can conveniently overturn the connecting part, and meanwhile, the connecting and fixing effects between the connecting part and the driving structure 241 are good.

In this embodiment, the driving structure 241 is a driving motor. The inside of the roller brush 242 is provided with a hollow structure which allows one end of the driving motor to penetrate into the inside of the roller brush 242, so that the roller brush 242 can be supported and fixed by the outer cylinder of the driving motor, and at the same time, the roller brush 242 can be driven to rotate. And the other end of the driving motor is fixed to the inner side of the connection part 251. It will be appreciated that in other embodiments, the driving structure may include a driving motor and a transmission mechanism, where the transmission mechanism is disposed on the connection portion 251, a rotation shaft of the driving motor is connected to an input end of the transmission mechanism, and an output end of the transmission mechanism is detachably connected to the roller brush 242.

In this embodiment, the roller brush 242 is in a roller shape, and includes a roller and a sleeve covering the roller, wherein the sleeve is made of flexible or elastic material, and is suitable for cleaning the floor, such as sponge, flannelette or other materials. It should be noted that, in other embodiments, the roller brush 242 may also be a crawler-type roller brush that cleans the floor using the rotation of the cleaning belt. The rolling brush overturning structure can be applied to surface cleaning equipment, and the surface cleaning equipment can be products which contain rolling brushes for cleaning, such as dust collectors, sweeping robots and floor washing machines.

In the present embodiment, the number of the cleaning modules 240 may be, but not limited to, two, and may be disposed on one side of the connection portion 251, and may be disposed on an inner side surface of the connection portion 251. Specifically, the two driving structures 241 are disposed in parallel on the inner side surface of the connecting portion 251, and the two rolling brushes 242 are disposed in parallel. Since the two roller brushes 242 are arranged side by side, the cleaning ability of the surface cleaning apparatus 100 is further improved. It should be noted that, in other embodiments, the transmission mechanism of the driving structure 241 has two output ends disposed side by side, and each output end is connected to one rolling brush 242, so that the two rolling brushes 242 are disposed side by side.

In order to better turn over the roller brushes 242, the other end of at least one roller brush 242 is provided with a handle 243, and the handle 243 can be lifted upwards at the same time when turning over, so that the whole cleaning module 220 can be turned over more easily. Moreover, a buckling type handle can be arranged between the two rolling brushes 242, and the two handles 243 are buckled together, so that a user can conveniently overturn the rolling brushes 242. When disassembly is required, the clasp can be opened and the two handles 243 can be separated.

The rotational angle range of the roller brush 242 with respect to the surface to be cleaned or the base 210 may be set between 5 deg. and 180 deg.. When the roller brush 242 is turned over by 5 °, the other end thereof is lifted out of the base 210, i.e., the base 210 does not interfere with its removal; when the rolling brush 242 is turned by 90 degrees, the rolling brush 242 is vertically arranged relative to the horizontal plane, so that the rolling brush 242 can be better detached and observed; when the roller brush 242 is turned 180 deg., the roller brush 242 is completely turned out and is disposed in parallel with respect to the horizontal plane. It is apparent that the range of the turning angle of the roll brush 242 of the present application is not limited to the above numerical range, and may depend on the specific structures of the base 210, the roll brush 242, and the turning structure 250.

Referring to fig. 5, fig. 5 is a cross-sectional view showing a cleaning apparatus of a surface cleaning device according to a second embodiment of the present utility model, and the main differences between the surface cleaning device 100 according to the present embodiment and the surface cleaning device 100 according to the first embodiment are as follows:
