Referring to FIG. 1, a floor cleaning accessory 100 according to an embodiment of the present disclosure is shown and described. The floor cleaning attachment 100 basically comprises a base 10 adapted to be moved over a floor to be cleaned and a body 20 connected at a lower portion to the base 10. The base 10 includes a housing 11, and a suction nozzle 12 is provided at a bottom front portion of the housing 11. The body 20 comprises a body 21 and a rigid tube 22, the top of the rigid tube 22 is arranged with an interface 23 for fluid connection with a suction source (such as a vacuum cleaner, etc.), the interface 23 is configured to transmit the suction force of the suction source to the suction nozzle 12. The body 20 is mounted with a cleaning fluid tank 31 for storing a cleaning fluid (e.g., water, a cleaning solution containing an effective detergent component, etc.) and a soil solution tank 41 for storing soil solution. The cleaning fluid tank 31 distributes the cleaning fluid to a corresponding portion through a cleaning fluid distribution line (not shown) having one end connected thereto. The dirty liquid tank 41 is communicated with the suction nozzle 12 through a dirty liquid input pipeline, and an exhaust passage is arranged between the dirty liquid tank 41 and the interface 23. Both the dirty liquid tank 41 and the cleaning fluid tank 31 are detachably provided on the body 21, and the cleaning fluid tank 31 is located above the dirty liquid tank 41.

As shown in fig. 2, the housing 11 of the base 10 is composed of an upper cover 111 and a bottom case 112 which are engaged and fixed with each other. The interior of the housing 11 has a suction tube 13. The suction nozzle 12 is located on the bottom shell 112 and communicates with the suction tube 13. The suction nozzle 12 is preferably a flexible, flat nozzle construction. Dirt liquid and small particle dust is sucked into the suction pipe 13 through this suction nozzle 12. The bottom housing 112 also has a scrubber 14 mounted thereon, and the cleaning fluid in the cleaning fluid tank 31 is distributed to the scrubber 14. The scrubber 14 in this case is located at the rear side of the suction nozzle 12, the scrubber 14 being capable of scrubbing the floor to be cleaned with cleaning fluid. The scrubber 14 is elastically supported on the bottom case 112 by a pair of springs 16, and a lifting actuator 15 capable of moving the scrubber up and down is further provided on the housing 11, and the scrubber 14 can be lifted up and down between the working position and the non-working position with respect to the bottom case 112 by the action of the lifting actuator 15. Wherein, in the rest position, the bristles (not shown) at the bottom of the scrubber 14 are away from the floor to be cleaned; in the operative position, the bristles at the bottom of the scrubber 14 are positioned against the floor to be cleaned.

As shown in fig. 3 and 4, the lower portion of the body 21 has a rotating shaft portion 211, and the rotating shaft portion 211 is supported in the bottom shell 112 of the housing 11 and can drive the body 20 to rotate between the inclined position and the upright position relative to the base 10. Typically, when the body 20 is in the inclined position, as shown, the entire floor cleaning attachment 100 is in operation; when the body 20 is in the upright position, the floor cleaning accessory 100 is in the stowed condition. In this example, in order to keep the body 20 in the upright position when the body 20 is in the upright position, a locking mechanism (not shown in the figure) capable of locking the body 20 in the upright position is further provided between the body 20 and the base 10. The locking mechanism may be of conventional construction and will not be described in detail herein.

In order to effectively control whether the cleaning fluid dispensing line (not shown) needs to dispense the cleaning fluid to the scrubber 14, as shown in fig. 2-4, a valve 33 is provided in the cleaning fluid dispensing line, and the valve 33 is fluidly connected in series to the cleaning fluid dispensing line to control whether the cleaning fluid dispensing line is connected to the outside. The valve 33 of this embodiment includes a valve body 331 and a valve member 332 provided on the valve body 331 through an elastic member (not shown), and the valve member 332 is slidable in and out of a valve chamber (not shown) defined by the valve body 331. Wherein, when the valve core 332 slides into the valve cavity, the valve 33 is opened; when the valve core 332 is outside the valve cavity, the valve 33 is closed. The specific operation of the valve 33 in this example is: when the valve core 332 is continuously pressed, the valve core can be kept in the valve cavity in the valve body 331, so that the valve 33 is in an open state; when the pressing force on the valve core 332 is removed and the valve core 332 enters the non-stressed state, the valve core 332 is ejected from the valve cavity of the valve body 331 by the elastic force of the elastic member, i.e., the valve 33 enters the closed state.

As shown in fig. 2, in order to facilitate control of the valve 33, a switch mechanism 34 is provided, and the switch mechanism 34 includes an operation key 341 rotatably supported on the bottom case 112 and having a portion exposed from the top surface of the upper cover 111, the operation key 341 in this example being a switch for a user to step on.

As shown in FIG. 3, when the user presses the operation key 341 with his foot to rotate it in a counterclockwise direction, the operation key 341 rotates and presses the valve core 332 of the valve 33 to slide into the valve cavity in the valve body 331, at which time the valve 33 will be opened, the cleaning fluid distribution pipeline enters the passage, and the cleaning fluid in the cleaning fluid tank 31 will continuously flow into the scrubbing brush 14 for cleaning. If the operation key 341 is rotated clockwise, the rotation of the operation key 341 will make the operation key 341 away from the valve core 332, at which time the valve core 332 will lose the pressing force of the operation key 341, the valve core 332 will pop out from the valve body 331, the valve 33 is closed, at which time the cleaning fluid distribution pipeline is cut off, and the cleaning fluid in the cleaning fluid tank 31 stops flowing to the scrubbing brush 14.

As shown in fig. 2, 4, and 5, a swing lever 35 is provided inside the housing 11 at a position close to the operation key 341. The swing lever 35 in this example abuts on the rotating shaft portion 211 of the body 21, and the swing lever 35 is movable in accordance with the rotation of the body 20, specifically: when the body 20 is shifted from the inclined position to the upright position, the rotating shaft portion 211 drives the swinging rod 35 to move toward the operating key 341 side during the rotation process, the swinging rod 35 moves to abut against the operating key 341 and further drives the operating key 341 to rotate clockwise, after the operating key 341 rotates clockwise, the operating key 341 moves away from the valve core 332, the valve core 332 pops out of the valve body 331 after losing the pressing force of the operating key 341, and the valve 33 is closed.

As shown in fig. 6 and 7, when the second body 20 is in the inclined position, the swing lever 35 is away from the operation key 341, and the operation key 341 is not blocked, and the user can open the valve 33 by depressing the operation key 341.

As shown in fig. 8 and 9, at this time, the second body 20 is still in the inclined position, the swing lever 35 is away from the operation key 341, the user presses the operation key 341 to rotate the operation key 341 in the counterclockwise direction, the operation key 341 presses the valve core 332 forward, the valve core 332 slides into the valve body 331, and the valve 33 is opened.

As shown in fig. 10 and 11, when the body 20 is held in the upright position, the rotary shaft portion 211 continuously abuts against the swing lever 35, the operation key 341 is separated from the valve body 332, and the valve 33 is closed.

As shown in fig. 8-10, if the user rotates the body 20 from the inclined position to the upright position, at this time, the rotating shaft portion 211 will drive the swing lever 35 to swing toward the side close to the operation key 341 along with the rotation of the body 20, and when the swing lever 35 swings to abut against the operation key 341, the operation key 341 will be driven by the swing lever 35 to rotate clockwise along with the continuous swing of the swing lever 35, i.e., the operation key 341 is far away from the valve core 332, and once the operation key 341 completely leaves the valve core 332, the valve 33 will be closed. While the body 20 is kept in the upright position, the swing lever 35 is always in contact with the operating key 341, which effectively prevents the operating key 341 from rotating counterclockwise, and the swing lever 35 is always away from the valve core 332, so that the valve 33 is continuously in the closed state.

As shown in fig. 6, 7, 9 and 10, when the user turns the second body 20 from the upright position to the inclined position, the swing lever 35 is moved toward the side away from the operation key 341 by being driven by the rotation shaft portion 211, at this time, the operation key 341 is released from the counterclockwise rotation restriction, and the user can actuate the valve 33 to open by stepping on the operation key 341.

In this embodiment, the base 10 and the body 20 are electrically isolated, i.e., no electrical load is applied to the base 10 and the body 20. Thus, by designing the valve 33 and the switch mechanism 34 as above, the user can stop the delivery of cleaning fluid to the brush assembly 15 while stopping the operation of the floor cleaning attachment 100, thereby effectively preventing the user from forgetting to close the valve 33 after stopping the operation of the floor cleaning attachment 100.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
