Detailed Description

In order to describe the technical content, constructional features, achieved objects and effects of the invention in detail, the following description will be made with reference to 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. The surface cleaning apparatus 100 basically includes a base 10 adapted to be moved over a surface to be cleaned, a body 20 having a lower portion connected to the base 10, a cleaning liquid distribution system and a dirty liquid recovery system. 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 main body 21 and a wand 22. The top of the wand 22 is provided with an interface 23 for fluid connection with a suction source (e.g. a vacuum cleaner or the like), the interface 23 being configured to be able to transfer the suction force of 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, 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 example, the cleaning solution distribution system and the dirty solution recovery system are both arranged on the base 10 and the machine body 20 at the same time; wherein, dirty liquid tank 41 and clean liquid tank 31 are all detachable setting on fuselage 21, and clean liquid tank 31 is located dirty liquid tank 41's top.

As shown in fig. 2, the housing 11 of the base 10 is composed of an upper cover 111 and a bottom case 112 that 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 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 tube 13. The bottom case 112 also has a scrubber 14 mounted thereto, and the cleaning liquid in the cleaning liquid 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 a surface to be cleaned with a cleaning liquid.

As further 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 is capable of rotating the body 20 between an inclined position and an upright position with respect to the base 10. Generally, as shown, when the body 20 is in the tilted position, the entire surface cleaning apparatus 100 is in an operative state; when the body 20 is in the upright position, the surface cleaning apparatus 100 is in the stowed condition. In this case, in order to keep the body 20 in the upright position all the time when it is in the upright position, a locking mechanism (not shown in the drawings) 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 a conventional construction and is not described in detail herein.

In order to effectively control whether the cleaning liquid output line (not shown) in the cleaning liquid distribution system needs to distribute the cleaning liquid to the scrubber 14, a valve 33 is provided in the cleaning liquid output line, and the valve 33 is fluidly connected to the cleaning liquid output line to control the flow rate of the cleaning liquid through the cleaning liquid output line, and in particular, whether the cleaning liquid output line is connected or not, as shown in fig. 2 to 4. The valve 33 of the present example includes a valve body 331 and a valve spool 332 provided on the valve body 331 by an elastic member (not shown), the valve spool 332 being slidable in and out of a valve chamber (not shown) defined by the valve body 331. Wherein the valve 33 is open when the valve spool 332 is positioned within the valve cavity; when the spool 332 is outside the valve cavity, the valve 33 is closed. The specific operation of the valve 33 in this example is: the valve 33 is in an open state by being held in a valve chamber in the valve body 331 when a pressing force is continuously applied to the valve body 332; when the pressing force of the valve body 332 is released, the valve body 332 is in an undeployed state, and the elastic force of the elastic component of the valve body 332 is released from the valve cavity of the valve body 331, namely, the valve 33 is in a 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 stepping by a user.

As shown in fig. 3, when the user rotates the operation key 341 around the counterclockwise direction by stepping on the foot, 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 is opened, the cleaning liquid output pipeline enters the passage, and the cleaning liquid in the cleaning liquid tank 31 continuously flows into the scrubber 14 for cleaning. If the operation key 341 rotates clockwise, the operation key 341 rotates away from the valve core 332, the valve core 332 loses the pressing force of the operation key 341, the valve core 332 is ejected from the valve body 331, the valve 33 is closed, the cleaning liquid output line is cut off, and the cleaning liquid in the cleaning liquid tank 31 stops flowing to the scrubber 14.

As shown in fig. 2,4, and 5, the swing lever 35 is provided inside the housing 11 at a position close to the operation key 341. In this example, the swing lever 35 is in contact with the rotation shaft portion 211 of the body 21, and the swing lever 35 is rotatable and movable with the body 20, as shown in fig. 3 to 4, specifically: when the body 20 is shifted from the inclined position to the upright position, the rotation shaft portion 211 will drive the swing lever 35 to move toward the operation key 341 side during rotation, the swing lever 35 will move to abut against the operation key 341 and further drive the operation key 341 to rotate clockwise, when the operation key 341 rotates clockwise, the operation key 341 will be away from the valve body 332, the valve body 332 will be sprung out of the valve body 331 after the pressing force of the operation key 341 is lost, and the valve 33 is closed.

As shown in fig. 6, when the second body 20 is located at the inclined position, the swing lever 35 is away from the operation key 341, at which time the operation key 341 is not blocked, the user can rotate it around the counterclockwise direction by stepping on the operation key 341, i.e., the user can drive the valve body 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 kept in the upright position, the rotating shaft portion 211 is continuously in contact with the swing lever 35, the operation key 341 is away from the valve body 332, and the valve 33 is closed.

If the user turns the body 20 from the inclined position to the upright position, the rotation shaft portion 211 will then, with the rotation of the body 20, drive the swing lever 35 to swing toward the side close to the operation key 341, and when the swing lever 35 swings to abut against the operation key 341, with continued swinging of the swing lever 35, the operation key 341 will be driven by the swing lever 35 to rotate in the clockwise direction, i.e., such that the operation key 341 is away from the valve element 332, and once the operation key 341 is completely separated from the valve element 332, the valve 33 will be closed. While the body 20 is kept in the upright position, the swing lever 35 is always abutted against the operation key 341, so that the operation key 341 is effectively prevented from rotating counterclockwise, the swing lever 35 is always away from the valve element 332, and the valve 33 is kept 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 the rotation shaft portion 211, at which 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.

As shown in fig. 2-3, the housing 11 is provided with a lift actuator 15. The scrubber 14 has a strip shape and has a pair of bosses 141 at the rear end thereof. The scrubber 14 can be supported on the bottom housing 112 by a pair of springs 16, and the scrubber 14 can be movable relative to the bottom housing 112 between an operative position and an inoperative position. Wherein in the inactive position, bristles (not shown) at the bottom of the scrubber 14 are spaced away from the surface to be cleaned; in the working position, the bristles at the bottom of the scrubber 14 are in close proximity to the surface to be cleaned. A lifting actuator 15 is attached to the bottom shell 112 and the scrubber 14 for lifting the scrubber 14 between an operating position and a non-operating position. Lifting actuator 15 is slidably disposed on bottom case 112 in the left-right direction, lifting actuator 15 is provided with sliding operation portion 151, rear side wall of bottom case 112 is provided with notch 1121, sliding operation portion 151 extends from notch 1121 to outside for user operation.

As shown in fig. 8 to 9, the lift actuator 15 is provided with a pair of inclined surfaces 152. When the slide operation portion 151 is operated in the left-right direction, the pair of inclined surfaces 152 will push the boss 141 on the scrubber 14 to move up and down, thereby achieving up-down movement of the scrubber 14 between the operating position and the non-operating position.

The electric loads are not arranged on the base 10 and the machine body 20 in the embodiment, namely, the base 10 and the machine body 20 are parts without electricity, and the structural design of the scrubbing brush is added, so that the surface cleaning device 100 can well meet the wet cleaning requirement.

The surface cleaning apparatus shown in fig. 10 is composed of a detachable hand-held vacuum cleaner 500 and the surface cleaning device 100 described above, wherein the hand-held vacuum cleaner 500 is provided with a battery 501 and a suction motor 502 as well as a dust separator 503, and an intake nipple 504 on the hand-held vacuum cleaner 500 is interconnected with the interface 23 at the upper end of the wand 22. The hand-held vacuum cleaner 500 is only in air flow communication with the surface cleaning apparatus 100 and there is no electrical connection therebetween.

When the user operates the handle 505 of the hand-held vacuum cleaner 500 such that the body 20 is rotated to the inclined position, the user steps on the operation key 341, the valve 33 will be opened, the scrubber 14 is driven to descend to the working position by the sliding operation part 151, the cleaning liquid in the cleaning liquid tank 31 will continuously flow to the scrubber 14, the scrubber 14 will move on the surface to be cleaned together with the housing 11 under the carrying action of the housing 11, and friction cleaning with the surface to be cleaned is achieved during the movement. The scrubber 14 rubs against the floor as the base 11 moves over the floor to effect wet cleaning, whereupon vacuum suction is generated at the suction motor 502 of the hand-held vacuum cleaner 500, which suction will eventually be transferred to the suction nozzle 12, the suction nozzle 10 will draw the dirt liquid communication air after the scrubbing of the dirt liquid scrubber 14 into the dirt liquid tank 41 together with the dirt liquid, which will be retained and stored in the dirt liquid tank 41, the air being expelled from the exhaust passage between the dirt liquid tank 41 and the interface 23 and then into the hand-held vacuum cleaner 500 and out to the outside after flowing from the suction motor 502 of the hand-held vacuum cleaner 500.

The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
