Detailed Description

For the purpose of illustrating the technical content, the constructional features, the achieved objects and the effects of the invention in detail, reference will be made to the following detailed description of the embodiments in conjunction with the accompanying drawings.

Referring to FIG. 1, a surface cleaning apparatus 100 according to an embodiment of the present disclosure is shown and described. Surface cleaning apparatus 100 generally comprises a base 10 adapted to be moved over a surface to be cleaned, a body 20 attached underneath base 10, a cleaning liquid distribution system, and a soiled liquid recovery system. The base 10 comprises a housing 11, and a suction nozzle 12 is arranged at the front part of the bottom of the housing 11. The body 20 comprises a body 21 and a rigid tube 22, and an interface 23 is disposed on the top of the rigid tube 22 for fluid connection with a suction source (e.g., a vacuum cleaner, etc.), and the interface 23 is configured to transmit suction from the suction source to the suction nozzle 12. The cleaning liquid distribution system mainly includes a cleaning liquid tank 31 for storing the cleaning liquid, a cleaning liquid output line fluidly connected to the cleaning liquid tank 31 to distribute the cleaning liquid to the corresponding portion, and the like. The dirty liquid recovery system mainly comprises a dirty liquid tank 41 and the like, wherein the dirty liquid tank 41 is communicated with the suction nozzle 12 through a dirty liquid input pipeline, and an exhaust channel is arranged between the dirty liquid tank 41 and the interface 23. In this embodiment, the cleaning solution distribution system and the dirty solution recovery system are both disposed on the base 10 and the body 20 at the same time; wherein, dirty liquid tank 41 and cleaning solution tank 31 are both detachably arranged on fuselage 21, and cleaning solution tank 31 is located the top of 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 duct 13. The suction nozzle 12 here is preferably of a flexible, flat suction nozzle construction. Dirt liquid and small particle dust is sucked through this suction nozzle 12 into the suction duct 13. The bottom housing 112 also has a scrubber 14 mounted thereon, and cleaning solution in the cleaning solution tank 31 is distributed to the scrubber 14. The scrubber 14 in this example is located at the rear side of the suction nozzle 12, the scrubber 14 being capable of scrubbing the surface to be cleaned with a cleaning liquid.

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 tilted position, as shown, the entire surface cleaning apparatus 100 is in operation; when the machine body 20 is in the upright position, the surface cleaning apparatus 100 is in the stowed state. 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 liquid outlet line (not shown) of the cleaning liquid distribution system needs to distribute the cleaning liquid to the scrubber 14, as shown in fig. 2-4, a valve 33 is arranged in the cleaning liquid outlet line, and the valve 33 is fluidly connected in series to the cleaning liquid outlet line for controlling the flow of the cleaning liquid through the cleaning liquid outlet line, in particular, whether the cleaning liquid outlet line is connected or not. 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 spool 332 is positioned within the valve cavity, the valve 33 is open; 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 steps on the operation key 341 to rotate it in the 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 this time, the valve 33 will be opened, the cleaning liquid outlet pipe enters the passage, and the cleaning liquid in the cleaning liquid 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 liquid output pipeline is cut off, and the cleaning liquid in the cleaning liquid 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, 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, so that the user can rotate the valve plug 332 in the counterclockwise direction by stepping on the operation key 341, that is, the user can drive the valve plug 332 to rotate by stepping on the operation key 341 to open the valve 33.

As shown in fig. 7, when the body 20 is held in the upright position, the rotary shaft portion 211 continuously abuts on the swing lever 35, the operation key 341 is separated from the valve body 332, and the valve 33 is closed.

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, that is, 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.

When the user turns the second body 20 from the upright position to the inclined position, the swing lever 35 is moved toward a side away from the operation key 341 by being driven by the rotation shaft portion 211, at this time, the counterclockwise rotation restriction of the operation key 341 is released, and the user can actuate the valve 33 to open by stepping on the operation key 341.

As shown in fig. 2-3, a lift actuator 15 is provided on the housing 11. The scrubbing brush 14 is a long strip, and has a pair of posts 141 at the rear end. The scrubber 14 can be supported on the bottom housing 112 by a pair of springs 16, the scrubber 14 being movable relative to the bottom housing 112 between an operative position and an inoperative position. Wherein, in the rest position, the bristles (not shown) at the bottom of the scrubber 14 are spaced away from the surface to be cleaned; in the operative position, the bristles at the bottom of the scrubber 14 are positioned against the surface to be cleaned. A lift actuator 15 is attached to the base 112 and the scrubber 14 for lifting the scrubber 14 between the working and non-working positions. The lifting actuator 15 is disposed on the bottom case 112 in a manner that the lifting actuator 15 can slide in the left-right direction, the lifting actuator 15 is provided with a sliding operation portion 151, a notch 1121 is disposed on a rear side wall of the bottom case 112, and the sliding operation portion 151 extends out from the notch 1121 for operation by a user.

As shown in fig. 8-9, a pair of ramps 152 are provided on the lift actuator 15. When the sliding operation part 151 is operated in the left and right directions, the pair of inclined surfaces 152 push the convex columns 141 on the scrubber 14 to move up and down, thereby realizing the up and down movement of the scrubber 14 between the working position and the non-working position.

In this embodiment, no electric load is disposed on the base 10 or the body 20, that is, the base 10 and the body 20 are not electric components, so that the surface cleaning apparatus 100 can well meet the wet cleaning requirement due to the structural design of the scrubbing brush.

A surface cleaning apparatus as shown in figure 10 is comprised of a detachable hand-held vacuum cleaner 500 and the surface cleaning apparatus 100 described above, wherein the hand-held vacuum cleaner 500 has a battery 501 and a suction motor 502 and a dust separator 503, and an air inlet stub 504 on the hand-held vacuum cleaner 500 is interconnected with the interface 23 at the upper end of the wand 22. The handheld vacuum cleaner 500 is in airflow communication with the surface cleaning apparatus 100 only and there is no electrical connection between the two.

When the user operates the handle 505 of the hand-held vacuum cleaner 500 to rotate the body 20 to the inclined position, the user steps on the operation key 341, the valve 33 is opened, the scrubbing brush 14 is driven to descend to the working position by the sliding operation part 151, the cleaning liquid in the cleaning liquid tank 31 continuously flows to the scrubbing brush 14, the scrubbing brush 14 moves on the surface to be cleaned along with the housing 11 under the carrying action of the housing 11, and friction cleaning with the surface to be cleaned is realized during the moving process. The scrubbing brush 14 rubs with the floor to realize wet cleaning as the base 11 moves on the floor, at this time, the suction motor 502 of the hand-held vacuum cleaner 500 generates vacuum suction force, the suction force is finally transmitted to the suction nozzle 12, the suction nozzle 10 sucks the dirty liquid communication air after the scrubbing cleaning of the dirty liquid scrubbing brush 14 into the dirty liquid tank 41, the dirty liquid is retained and stored in the dirty liquid tank 41, the air is discharged from the exhaust passage between the dirty liquid tank 41 and the interface 23, then enters the hand-held vacuum cleaner 500, and is discharged to the outside after flowing through the suction motor 502 of the hand-held vacuum cleaner 500.
