Description

Floor cleaning accessory

Technical Field

The present invention relates to the field of cleaning apparatus and in particular to a floor cleaning accessory for mounting to a vacuum cleaner.

Background

In daily life, people generally clean indoor floors by using a vacuum cleaner to suck dust particles and the like on the floors. However, when a stubborn stain is present on the floor, the floor cannot be thoroughly cleaned by the common vacuum cleaner. A wet cleaning machine with a water washing function is required to accomplish the cleaning of stubborn stains at this time.

In the patent application publication CN109832998a cleaning head device is disclosed which is capable of performing cleaning of liquid by simple combination with a dry vacuum cleaner commonly available in the home, the cleaning head device carrying a roller brush, a cleaning water tank and a dirty liquid tank. When the cleaning head works, the water in the clean water tank is continuously conveyed to the rolling brush by the pump, and then the intractable stains are frequently removed by the water matched with the rolling brush. The cleaning head device can well expand the functions of a common dry vacuum cleaner, so that a user can realize a wet cleaning function without purchasing an expensive wet cleaning machine additionally.

The above-described cleaning head also has the disadvantage that the use of a pump tends to increase the manufacturing cost. If the water flow is controlled by the valve, the user is likely to forget to close the valve after the cleaning is finished, and the water in the clean water tank still continuously flows outwards due to the fact that the fluid conveying channel is not closed, so that the ground is polluted.

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 floor cleaning accessory 100 in accordance with an embodiment of the present disclosure is shown and described. The floor cleaning accessory 100 basically includes a base 10 adapted to be moved over a floor to be cleaned and a body 20 having a lower portion connected to the base 10. The base 10 comprises a housing 11, and a suction nozzle 12 is arranged at the front bottom of the housing 11. The body 20 comprises a main body 21 and a wand 22, the top of the wand 22 being provided with an interface 23 for fluid connection with a source of suction (e.g. a vacuum cleaner or the like), the interface 23 being configured to be able to transfer the suction of the source of suction to the suction nozzle 12. A cleaning fluid tank 31 for storing a cleaning fluid (e.g., water, a cleaning solution containing an effective detergent component, etc.) and a dirty liquid tank 41 for storing a dirty liquid are mounted on the body 20. The cleaning fluid tank 31 distributes the cleaning fluid to the corresponding portions through a cleaning fluid distribution line (not shown) connected at one end portion thereof. 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. Both the dirty liquid tank 41 and the clean fluid tank 31 are detachably provided on the main body 21, and the clean 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 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 flexible, flat-shaped suction nozzle construction. The dirt liquid and small particle dust is sucked into the suction tube 13 through this suction nozzle 12. The bottom shell 112 also has a scrubber 14 mounted thereto, and cleaning fluid within the cleaning fluid tank 31 is dispensed to the scrubber 14. The scrubber 14 in this example is located on the rear side of the suction nozzle 12, the scrubber 14 being capable of scrubbing the floor to be cleaned with a 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 an operating position and a non-operating position with respect to the bottom case 112 by an action of the lifting actuator 15. Wherein in the inactive position, bristles (not shown) at the bottom of scrubber 14 are spaced away from the floor surface to be cleaned; in the working position, the bristles at the bottom of the scrubber 14 are in close proximity to the floor to be cleaned.

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. Typically, the entire floor cleaning accessory 100 is in operation when the machine body 20 is in the reclined position as shown; with the body 20 in the upright position, the floor cleaning accessory 100 is in a 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 fluid distribution line (not shown) needs to be distributed to the scrubber 14, as shown in fig. 2 to 4, a valve 33 is provided in the cleaning fluid distribution line, and the valve 33 is fluidly connected to the cleaning fluid distribution line to control whether the cleaning fluid distribution line is connected to the outside. 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 when the valve spool 332 slides into the valve cavity, the valve 33 is opened; 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 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 scrubber 14 for cleaning. If the operation key 341 rotates clockwise, the operation key 341 rotates away from the valve body 332, the valve body 332 loses the pressing force of the operation key 341, the valve body 332 is ejected from the valve body 331, the valve 33 is closed, the cleaning fluid distribution line is shut off, and the cleaning fluid in the cleaning fluid 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 and 7, 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, and the user can open the valve 33 by stepping on the operation key 341.

As shown in fig. 8 and 9, when the second body 20 is still in the inclined position, the swing lever 35 is away from the operation key 341, the user rotates the operation key 341 in the counterclockwise direction by stepping on the operation key 341, the operation key 341 is pressed forward against the valve body 332, the valve body 332 is slid into the valve body 331, and the valve 33 is opened.

As shown in fig. 10 and 11, when the body 20 is kept in the upright position, the rotation shaft portion 211 is continuously in contact with the swing lever 35, the operation key 341 is away from the valve element 332, and the valve 33 is closed.

As shown in fig. 8 to 10, if the user turns the body 20 from the inclined position to the upright position, at this time, the rotation shaft portion 211 will drive the swing lever 35 to swing toward the side close to the operation key 341 as the body 20 rotates, and when the swing lever 35 swings to abut against the operation key 341, the operation key 341 will be driven to rotate clockwise by the swing lever 35 as the swing lever 35 continues to swing, i.e., the operation key 341 is made to move 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.

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 a side away from the operation key 341 by the driving of 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.

The base 10 and the body 20 of this example are non-energized parts, i.e., no electric load is applied to the base 10 and the body 20. In this way, by the design of the valve 33 and the switch mechanism 34, the user can stop supplying cleaning fluid to the brush assembly 15 while stopping working with the floor cleaning accessory 100, thereby effectively preventing the occurrence of an event that the user forgets to close the valve 33 after stopping working with the floor cleaning accessory 100.

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.
