Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order.

The tank assembly 1 according to this embodiment mainly includes a foul water tank 11, a fresh water tank 12, and a switch 13. The present embodiment also provides a cleaning machine 2, where the cleaning machine 2 may include a device body 21 and a cleaning device 22, and the device body 21 includes a handle 211, a body 212, and a water tank assembly 1. The water tank assembly 1 is provided on the body 212, and the cleaning device 22 is provided on the device body 21. The cleaning device 22 is rotatably coupled to the body 212. The cleaning device 22 includes a housing, brush roller, cleaning roller, extrusion, filter, first motor, second motor, and the like.

The cleaning roller, the brush roller, the first motor, the second motor, the extrusion piece and the filter piece are all arranged in the shell. The first motor is used for driving the cleaning roller to rotate, and the second motor is used for driving the brush roller to rotate. The extrusion piece is used for extruding the sewage of the cleaning roller, and the filter piece is used for cleaning the sewage of the roller. The housing includes a return channel for storing and conducting the contaminated water of the cleaning drum. A garbage box for collecting garbage is arranged in the shell. Optionally, the housing, the extrusion, and the filter are integrally formed structures.

In the tank assembly 1, a dirty water tank 11 collects dirty water of the cleaning drum, and a clean water tank 12 provides clean water to clean the cleaning drum. The cleaner 2 further comprises a water pump and an air pump, wherein the water pump is connected with the clean water tank 12 through a water pipe and is used for sucking and outputting clean water in the clean water tank 12 to the cleaning roller; the air pump is connected with the sewage tank 11 through an air pipe to pump air to the sewage tank 11, so that the sewage tank is in a negative pressure state. The sewage tank 11 in a negative pressure state sucks sewage into the sewage tank 11.

When the cleaner 2 is in operation, the first motor drives the cleaning roller to rotate and clean the surface to be cleaned. The second motor drives the brush roller to brush the large garbage on the cleaning roller into the garbage box. The water pump sucks and outputs the purified water in the purified water tank 12 to the outer surface of the cleaning drum, thereby cleaning the cleaning drum. While the cleaning roller rotates, the extrusion presses the sewage of the cleaning roller, and the filtering piece cleans the sewage of the cleaning roller. The filtered sewage enters the return channel. The sewage tank 11 is in a negative pressure state by air pump suction, and the sewage tank 11 in the negative pressure state sucks sewage into the sewage tank 11.

It should be noted that the working sequence of each structural component of the cleaning machine 2 is not sequential, and should not be construed as limiting the application. However, the parts of the cleaning roller after cleaning the surface to be cleaned pass through the structural members in sequence. Specifically, the brush roller, the cleaning roller, the extrusion part and the filtering part are sequentially arranged along the moving direction of the cleaner 2, so that the part of the cleaning roller after cleaning the surface to be cleaned can pass through the brush roller first, and the brush roller brushes large-sized garbage such as hairs possibly attached to the surface of the cleaning roller to fall down to the garbage box; after the part of the cleaning roller, which is used for cleaning the surface to be cleaned, is cleaned by the purified water, the part of the cleaning roller, which is used for cleaning the surface to be cleaned, continuously passes through the extrusion part so as to extrude the sewage in the cleaning roller, and finally the sewage is filtered by the filtering piece.

The water tank assembly 1 provided in this embodiment includes a sewage tank 11 for accommodating sewage. Optionally, the sewage tank 11 includes a first cover and a first tank, where the first cover is detachable from the first tank, and the first cover and the first tank enclose a chamber for storing sewage together.

The shape of the fresh water tank 12 may be, but is not limited to, a cylinder or a cylinder-like shape, and the axial direction of the fresh water tank 12 may be understood as the extending direction of the center axis of the fresh water tank 12.

The tank assembly 1 provided in this embodiment further includes a switch 13 for controlling the fixed connection or separation of the foul water tank 11 from the fresh water tank 12. One end of the switch 13 is fixed to one of the foul water tank 11 and the fresh water tank 12, and the other end is capable of connecting and locking the other of the foul water tank 11 and the fresh water tank 12. The switch 13 can select whether or not the other end thereof is connected to or engaged with the other of the foul water tank 11 and the fresh water tank 12 by adjusting the state thereof.

On the one hand, when the foul water tank 11 is slidably connected to the fresh water tank 12, the switch 13 can connect the foul water tank 11 to the fresh water tank 12, thereby fixing the fresh water tank 12 to the foul water tank 11. At this time, the foul water tank 11 and the fresh water tank 12 can be used together as an integral unit, and when the foul water tank 11 is taken by the user, the fresh water tank 12 is taken at the same time, thereby improving the operability of the tank assembly 1 and facilitating the operation of the user. Therefore, the application saves space, increases capacity and is convenient for users to operate by combining the foul water tank 11 and the clean water tank 12. On the other hand, when the switch 13 is actuated, the switch 13 is separated from either the foul water tank 11 or the fresh water tank 12 so that the foul water tank 11 and the fresh water tank 12 are not in a fixedly coupled state, and both can be slidingly separated, that is, the foul water tank 11 and the fresh water tank 12 can be separated. At this time, the user can select to use either the foul water tank 11 or the clean water tank 12 separately, further improving the operability of the clean water tank 12 and the foul water tank 11, making the tank assembly 1 suitable for a plurality of scenes, and improving the user experience.

Therefore, in this embodiment, the foul water tank 11 and the clean water tank 12 can be slidingly connected or separated, and the switch 13 is matched, so that the foul water tank 11 and the clean water tank 12 can be fixedly connected or separated, thereby improving the operability and applicability of the water tank assembly 1 and improving the user experience.

Referring to fig. 1-5 together, fig. 5 is an enlarged view of a portion of the water tank assembly of the embodiment of fig. 4. In one embodiment, one of the fresh water tank 12 and the foul water tank 11 is provided with a first stopper 14, the other of the fresh water tank 12 and the foul water tank 11 includes a tank 111, the switch 13 is provided to the tank 111, the switch 13 includes a driving member 131, and a locking member 132, and the locking member 132 is slidable with respect to the tank 111.

When the foul water tank 11 is slidably engaged with the fresh water tank 12, the locking piece 132 abuts against the first stopper 14; when the driving member 131 is driven, the driving member 131 moves in a direction approaching the locking member 132 and abuts against the locking member 132, so that the locking member 132 slides in a direction away from the first limiting portion 14 and is separated from the first limiting portion 14.

For example, the side of the fresh water tank 12 facing the foul water tank 11 is provided with a first stopper 14. The sewage tank 11 includes a tank body 111 and a switch 13 provided in the tank body 111. The switch 13 is provided on the side of the tank 111 facing the fresh water tank 12. For another example, the foul water tank 11 is provided at a side facing the fresh water tank 12 with a first stopper 14. The fresh water tank 12 includes a tank 111 and a switch 13 provided in the tank 111. The switch 13 is provided at a side of the tank 111 facing the sewage tank 11. The first limiting portion 14 may be a protrusion or a groove. In this embodiment, the first limiting portion 14 is a protrusion, and when it is a groove, the locking member 132 is inserted into the groove for fixing connection.

The switch 13 provided in this embodiment includes a driving member 131 and a locking member 132. The driving member 131 is disposed at one side of the locking member 132. The driving member 131 can be moved relative to the case 111 by a user, so that the driving member 131 abuts against the locking member 132 or is separated from the locking member 132. The locking piece 132 can slide with respect to the case 111 to abut against or separate from the first stopper 14. When the locking piece 132 is abutted against the first limit portion 14, the foul water tank 11 and the fresh water tank 12 can be fixedly connected. When the locker 132 is separated from the first stopper 14, the foul water tank 11 is slidably separated from the fresh water tank 12.

For example, when the user drives the driving member 131 in a first direction (as shown in a direction D1 of fig. 5), the driving member 131 moves in the first direction and abuts against the locking member 132, so that the locking member 132 slides in a second direction (as shown in a direction D2 of fig. 5) perpendicular to the first direction and is separated from the first limiting portion 14. As shown in fig. 5, when the user drives the driving member 131 rightward, the driving member 131 moves rightward and abuts against the locking member 132, so that the locking member 132 slides upward and is separated from the first limiting portion 14.

In this embodiment, the driving member 131 and the locking member 132 are provided so that the user can control the switch 13 to connect the foul water tank 11 with the fresh water tank 12 or to separate the switch 13 from the foul water tank 11 or the fresh water tank 12 by driving the driving member 131, thereby achieving the fixed connection and separation of the foul water tank 11 and the fresh water tank 12. The driving member 131 and the locking member 132 included in the switch 13 may be combined into one body, and the sewage tank 11 and the fresh water tank 12 may be fixedly connected and separated by driving the combined body to move in the D2 direction.
