Fig. 1 is a schematic structural view of a surface cleaning apparatus according to one embodiment of the present disclosure.

As shown in fig. 1, the surface cleaning apparatus of the present disclosure is used for cleaning a floor surface to be cleaned, and preferably, the surface cleaning apparatus is capable of wet cleaning the floor surface to be cleaned and recovering liquid after cleaning the floor surface to be cleaned to the surface cleaning apparatus.

As shown in fig. 1, the surface cleaning apparatus may structurally include a handle portion 100, a frame portion 200, a cleaning liquid storage portion 300, a recovery storage portion 400, a connection portion 500, and a floor brush assembly 600.

In use, the floor brush assembly 600 of the present disclosure is configured to be movable over a floor surface to be cleaned to wet clean the floor surface to be cleaned by the floor brush assembly 600.

The handle portion 100 is used for operating the surface cleaning apparatus, more specifically, on the one hand, an operator can realize control of the posture of the surface cleaning apparatus by operating the handle portion 100, for example, by controlling the handle portion 100, the surface cleaning apparatus can be in a tilted state (i.e., an angle of approximately 60 ° with the surface to be cleaned) or in a substantially lying state (i.e., substantially parallel with the surface to be cleaned); accordingly, when the frame portion 200 of the surface cleaning apparatus is in an inclined state (i.e., at an angle of about 60 ° to the surface to be cleaned) or a substantially lying state (i.e., substantially parallel to the surface to be cleaned), the surface cleaning apparatus is in a cleaning mode and is capable of cleaning the surface to be cleaned. Accordingly, when the handle part 100 is operated such that the frame part 200 of the surface cleaning apparatus is in a vertical state, the surface cleaning apparatus is in a stopped state at this time, or the surface cleaning apparatus is in a base station, the frame part 200 of the surface cleaning apparatus is also in a substantially vertical state.

On the other hand, physical buttons may be provided on the handle portion 100, so that the surface cleaning apparatus may be controlled by the physical buttons, for example, controlling start and stop of the surface cleaning apparatus, controlling liquid supply speed and suction power of the surface cleaning apparatus, and the like, so that a user of the surface cleaning apparatus experiences better.

The handle portion 100 can be provided at an upper end of the frame portion 200, so that the surface cleaning apparatus can be operated by operating the handle portion 100. In the present disclosure, the frame part 200 is formed as a main force-receiving structure of the surface cleaning apparatus, and both the cleaning liquid storage part 300 and the recovery storage part 400 of the surface cleaning apparatus can be directly or indirectly fixed to the frame part 200.

The cleaning liquid storage part 300 is formed in the shape of a tank to store the cleaning liquid in the cleaning liquid storage part 300. In one embodiment, the cleaning liquid may be clean water. Of course, those skilled in the art will recognize that the cleaning liquid storage portion 300 may store a mixture of clean water and cleaning agent.

The frame part 200 is formed with a receiving space thereon, and the cleaning liquid storage part 300 can be disposed in the receiving space such that a portion of the outer surface of the cleaning liquid storage part 300 is formed as a portion of the outer surface of the surface cleaning apparatus.

In the present disclosure, the cleaning liquid storage part 300 is detachable from the frame part 200 and is manually filled with cleaning liquid by a user; of course, the cleaning liquid storage portion 300 of the present disclosure may also be filled with the cleaning liquid of the cleaning liquid storage portion 300 through the cleaning liquid interface provided on the frame portion 200.

Still further, when the cleaning liquid interface is provided on the frame part 200, the cleaning liquid storage part 300 may be provided inside the frame part 200, in which case the cleaning liquid storage part 300 is not formed as at least part of the outer surface of the surface cleaning apparatus.

In the present disclosure, in order to achieve cleaning of a surface to be cleaned, the cleaning liquid storage part 300 is connected to the floor brush assembly 600 at least through a cleaning liquid line, thereby supplying a cleaning liquid to the floor brush assembly 600 and thus achieving wet cleaning of the surface to be cleaned.

As shown in fig. 1, the frame part 200 is formed with a receiving space, and the recovery storage part 400 is detachably provided to the frame part 200 and is positioned in the receiving space, so that when the liquid stored in the recovery storage part 400 is more, a user can remove the recovery storage part 400, pour out the sewage inside and clean up the solid garbage, and at this time, a part of the outer surface of the recovery storage part 400 is formed as a part of the outer surface of the surface cleaning apparatus.

In order to recover the liquid after cleaning the surface to be cleaned, the recovery storage 400 can be connected to the floor brush assembly 600 through a recovery pipe 401, and accordingly, a mixture of sewage and gas (dirt) can be recovered to the recovery storage 400 through the recovery pipe 401.

Accordingly, the surface cleaning apparatus further comprises a suction device (not shown in the drawings), wherein the suction device is capable of generating a negative pressure and providing the negative pressure to the recovery storage 400, thereby realizing a forced flow of gas and sewage within the recovery line 401. In the present disclosure, the gas discharged from the suction device can flow to the outside of the surface cleaning apparatus through the slit on the part of the outer surface of the surface cleaning apparatus.

The frame part 200 is connected to the floor brush assembly 600 through the connection part 500 such that the frame part 200 is pivotably connected to the floor brush assembly 600, and in the present disclosure, the frame part 200 has at least two rotational degrees of freedom with respect to the floor brush assembly 600, thereby enabling a user to more conveniently operate the surface cleaning apparatus.

The structure of the floor brush assembly 600 is described in detail with reference to the accompanying drawings.

Fig. 2 is a schematic structural view of a floor brush assembly according to one embodiment of the present disclosure. Fig. 3 and 4 are partial structural schematic diagrams of a floor brush assembly according to one embodiment of the present disclosure.

In the present disclosure, as shown in fig. 2 to 4, the floor brush assembly 600 may include a frame portion 610, a suction nozzle 620, a stirring member 630, a cover 640, a flexible vacuum hose 650, and the like.

The frame portion 610 is configured to be connected to the frame portion 200 by the connection portion 500, and the frame portion 610 is adapted to be moved over a floor surface to be cleaned. For example, the frame 610 may include two rolling wheels, and the frame 610 is moved over the surface to be cleaned by movement of the rolling wheels over the surface to be cleaned.

The frame 610 can define a receiving cavity for the brush assembly, the receiving cavity being located in the front half of the brush assembly (forward of the direction of movement of the surface cleaning apparatus when cleaning a surface to be cleaned) so as to receive the stirring element 630 therein, and accordingly the stirring element 630 is also located in the front half of the brush assembly.

As shown in fig. 4, the frame 610 has a suction nozzle 620 formed thereon, and defines a dirt inlet to the recycling line 401 through the suction nozzle 620, and in the present disclosure, the suction nozzle 620 is disposed adjacent to the stirring member 630 and behind the stirring member 630. In the present disclosure, the suction nozzle 620 is connected to the recovery line 401 through a flexible vacuum hose 650, and is formed as a starting point of a recovery path.

In the present disclosure, the relative positions of the suction nozzle 620 and the inlet of the recovery pipeline 401 can be changed under the action of external force; for example, when the surface cleaning apparatus is in an upright position, the suction nozzle 620 is in a first positional relationship with the inlet of the recovery conduit 401; the suction nozzle 620 and the inlet of the recovery duct 401 form a second positional relationship when the surface cleaning apparatus is in a lying state, the first and second positional relationships being different, that is, the relative positions of the suction nozzle 620 and the inlet of the recovery duct 401 can be changed when the angle between the frame portion 200 and the brush assembly 600 is different.

The agitator 630 is configured to agitate the floor surface to be cleaned; that is, when the surface cleaning apparatus is performing a cleaning operation or a self-cleaning operation, the stirring member 630 can be rotated by being driven by a motor, whereby the stirring member 630 can be brought into frictional contact with the floor surface to be cleaned and cleaning of the floor surface to be cleaned is achieved. During frictional contact of the stirring member 630 with the floor surface to be cleaned, the cleaning liquid can be supplied to the stirring member 630, thereby achieving wet cleaning of the floor surface to be cleaned.

In the present disclosure, the stirring member 630 is rotatable along a first axis; more preferably, the first axis may be a horizontal straight line of a lateral direction, i.e., a direction perpendicular to the front-rear direction; the front-rear direction is a moving direction of the surface cleaning apparatus when cleaning a surface to be cleaned.

The cover 640 is disposed on the frame 610 and is configured to partially surround the stirring member 630; in one embodiment, the cover 640 is also formed as part of the receiving cavity. In other words, the cover 640 and the frame 610 together form the accommodating chamber.

The flexible vacuum hose 650 defines a fluid transfer conduit from the suction nozzle 620 to the inlet of the recovery line 401, and at least a portion of the inner wall surface of the flexible vacuum hose 650 remains continuously smooth as the relative position of the suction nozzle 620 and the recovery line 401 inlet changes.

Therefore, the flexible vacuum hose 650 disclosed by the utility model is not easy to remain dirt through a special structural design, and the flexible vacuum hose 650 can be prepared from HDPE material, and the material has the advantages of good flexibility, high ring stiffness, good pressure resistance, corrosion resistance, ageing resistance and the like.

Further, since dirt is not easily attached to the inner wall surface of the flexible vacuum hose 650, secondary pollution is not caused; and the liquid flow resistance in the flexible vacuum hose 650 is small, so that the suction device can realize the recovery of dirt with lower power, save energy and improve the cruising time of the surface cleaning equipment.

Fig. 5 is a schematic structural view of a flexible vacuum hose according to one embodiment of the present disclosure. Fig. 6 is a schematic cross-sectional structural view of a flexible vacuum hose according to one embodiment of the present disclosure.

As shown in fig. 5 and 6, the flexible vacuum hose 650 includes an inner tube 651 and an outer tube 652 sleeved outside the inner tube 651, and the inner tube 651 and the outer tube 652 are connected by at least one connection member 653.

In the present disclosure, in one embodiment, the inner tube 651, outer tube 652, and connector 653 can be separately formed and assembled together; in another embodiment, the inner tube 651, outer tube 652 and connector 653 can be integrally formed.

The inner wall surface of the inner tube 651 is smooth, whereby dirt and the like can smoothly flow from the inner wall surface of the inner tube 651 and does not adhere to the inner wall surface of the inner tube 651.

The inner wall of the outer tube 652 is connected to the outer wall of the inner tube 651 by at least one connector 653, such that the flexible vacuum hose 650 is formed as a single body.

Preferably, the connector 653 is an annular connector, and accordingly, an inner wall surface of the annular connector is connected to an outer wall surface of the inner tube 651, and an outer wall surface of the annular connector is connected to an inner wall surface of the outer tube 652.

In the present disclosure, the outer tube 652 is a bellows; accordingly, the inner wall surface of the outer tube 652 has peaks and valleys; more specifically, the peaks of the inner wall surface of the outer tube 652 correspond to the valleys of the outer wall surface of the outer tube 652, and the valleys of the inner wall surface of the outer tube 652 correspond to the peaks of the outer wall surface of the outer tube 652.

The connection member 653 is connected to the peak position of the inner wall of the outer tube 652, thereby enabling the size of the connection member 653 to be as small as possible, and accordingly, the inner tube 651 and the outer tube 652 have higher strength.

When the relative positions of the suction nozzle 620 and the inlet of the recovery line 401 are changed, the inner tube 651 and the outer tube 652 are bent in the same direction with the connecting member 653 as a fulcrum.

In the present disclosure, the inner tube 651 and the outer tube 652 are connected at both ends and are formed as an inlet section 654 and an outlet section 655 of the flexible vacuum hose 650, wherein inner wall surfaces and outer wall surfaces of the inlet section 654 and the outlet section 655 are each formed as smooth surfaces to facilitate connection of the flexible vacuum hose 650 of the present disclosure to the suction nozzle 620 and the recovery line 401.
