When implemented, it is well understood that the drive member 5 is capable of opening the gap 4 at a certain rotational speed by adjusting a weight of the drive member 5, and a specific weight of the drive member 5 is not easy to be quantified here because the weight also needs to be tested and adjusted according to a weight of the lifting plate 22 and an accuracy (a sliding smoothness) that the product can actually achieve.
A guide groove 41 is located within the gap 4 and configured to guide the movement direction of the drive member 5, the guide groove 41 is opened at one of the lifting plate 22 or the fixed plate 21, and the guide groove 41 is oblique to form a structure in which the gap 4 is increasingly smaller from the center of the lifting plate 22 to the periphery of the lifting plate 22.
In this embodiment, as shown in
In this embodiment, two guide grooves 41 are provided (i.e., two drive members 5 are provided), and the configuration of at least two guide grooves 41 can achieve the balance of the mop head 2 when rotating, and after a sample test, two guide grooves 41 (the drive member) can well complete the action of opening the lifting plate 22 and have no influence on the balance of the mop head 2 and the rotation smoothness when the mop head 2 rotates.
Preferably, the drive member 5 is a sphere, and the sphere structure can reduce the friction when moving, so that the drive member 5 can move smoothly.
In this embodiment, the sphere is made of metal, the metal sphere has a certain weight, and a centrifugal force of the rotation can easily move the sphere toward the periphery to open the gap 4.
As shown in
As for the mop in this embodiment, the rotation of the mop head 2 may be achieved by a hand-pressed rotary mop rod 3 or the motor, both of which belong to the existing art, which will not be repeated.
Specific structures of the fixed plate 21 and the lifting plate 22 are shown in
In this embodiment, the mop rod 3 is connected to the boss 211 by a cross shaft so that the mop head 2 can rotate in a universal direction. The lifting plate 22 is further provided with a panel 24 for mounting the wipe, the panel 24 and the lifting plate 22 are detachably connected to each other.
A cleaning tool is as shown in
The penetrating drive part is also configured to form the support column 66 for supporting the working of the mop, the mop is supportable by the drive part to be capable of working rotatably, and an engaging part 72 is provided between the lifting plate 22 and the drive part so as to stop the lifting plate 22 and the drive part from rotating in a circumferential direction, when the lifting plate 22 is located at the low position, the engaging part is configured to engage to drive the pump 7 to work, and the pump 7 is configured to pump out the clean water and spray the clean water on the mop; and when the lifting plate 22 is located at the high position, the engaging part 72 is configured to disengage to cause the pump 7 to stop working and cause the mop to continue to rotate for dewatering.
The cleaning tool of the present disclosure does not need to be pulled manually at the time of switching between the cleaning operation and the dewatering operation, the operation of lifting and lowering the mop head 2 is completed by adjusting the rotational speed of the mop head 2 so as to achieve the seamless switching between cleaning and dewatering, and it also does not need to wait for the mop head 2 to stop rotating at the time of switching, saving time and labor. During cleaning, water is sprayed by the pump 7 to achieve good cleaning effect.
The mop bucket 6 of the present disclosure also has a function of separating the clean water and the dirty water. The mop bucket 6 is further provided with a dirty water area 63 which does not communicate with the clean water area 61 and communicates with the working area 62, and dirty water generated by the working of the mop in the working area can flow into the dirty water area 63.
In this embodiment, the mop bucket 6 includes a first bucket body 64 and a second bucket body 65 which are stacked in the upper and lower direction, the first bucket body 64 under the second bucket body 65 is the clean water area 61, the second bucket body 65 on the first bucket body 64 is the working area 62, and the clean water area 61 is also provided with a water injection port 611.
The periphery of the second bucket body 65 extends downward to form a receiving chamber 651. The receiving chamber 651 is the dirty water area 63, and the dirty water area 63 formed by the receiving chamber 651 extending downwardly is lower than the working area 62, thus the waste water generated in the working area 62 can automatically flow into the dirty water area 63 under an action of gravity.
As shown in
When the mop is operating in the working area 62, the roller 8 can form a certain squeeze with the wipe of the mop, and wastes on a surface of the wipe can be cleaned by the tines 81 on the surface thereof.

As shown in
In this embodiment, as shown in
Moreover, in this embodiment, the first blade and the second blade rotate synchronously and are both axial-flow blades, but have different blade angles. That is, different water outlet speeds are achieved through different blade angles. The blade angle refers to a water outlet angle of the blade, that is, an included angle between the blade and an end face of a wheel body. Different water outlet angles of the blades can provide different water pressures to achieve different water outlet speeds.
In this embodiment, the second blade is located below and is located at a water inlet 7741 communicating a clean water storage area and a pumping chamber for a first step of pumping. The second blade having a smaller blade angle pumps the clean water into the pumping chamber, and the first blade having a larger angle pumps the clean water out and sprays the clean water onto the mop. The first blade having the larger blade angle can provide a larger water pressure and flow velocity.
In addition, the pump housing 78 of the pump 7 may be configured as a conventional fixed structure, or a structure in which the pump housing 78 rotates in synchronization with the impeller 73 in this embodiment, and the pump housing 78 and the second blade are formed integrally in this embodiment.
More specifically, in the present disclosure, as shown in
In this embodiment, as shown in
The engaged structure of the rib 721 and the groove 722 is stable and can be molded for one time at the injection molding, which is easy to be manufactured.
The rotation axis of the impeller 73 in the present disclosure is arranged vertically, a plane bearing 75 is arranged between a lower end of the impeller 73 and the mop bucket 6. Since the drive shaft 731 protruding from the impeller 73 plays a role of supporting the mop head 2 simultaneously, especially when using a hand-pressed mop rod 3 in this embodiment, the impeller 73 is subjected to a large axial force and is liable to be worn when used for a long time. The plane bearing 75 is added, so that the rotation smoothness of the impeller 73 is improved and the service life of the impeller 73 is increased.
The working principle of the cleaning tool in this embodiment is as follows: the lifting plate 22 is located at a low position when the mop is in a normal state, the mop is arranged at the drive part to rotate for working, the engaging part is configured to engage to drive the pump 7 to pump out the clean water and spray the clean water on the mop to perform the clean operation of the mop. After cleaning for a certain time, a rotation speed of the mop head 2 is accelerated, and at a certain speed, the drive member 5 in the mop moves toward the periphery under the action of the centrifugal force, and the gap 4 arranged for reduction is opened so as to jack up the lifting plate 22 to the high position. In this case, the engaging part is configured to disengage to cause the pump 7 to stop working and cause the mop to continue to rotate for dewatering.
The difference between this embodiment and the embodiment one is a structure of a mop bucket 6.
In this embodiment, as shown in
In this embodiment, as shown in
The difference between this embodiment and the embodiment one is a structure of a drive member 5 on a mop and a structure of a gap engaged with the drive member 5.
As shown in
The spherical drive member 5 moves mainly by rolling, which may also be accompanied by sliding. When the spherical structure is adopted, the lifting plate 22 has a high sensitivity, that is, the lifting plate 22 can move without a high rotation speed to achieve the drive lifting. The block-shaped drive member 5 is slidable, and the rotation speed required by the movement is relatively high due to the influence of the friction force. In fact, there is no judgement of good or bad between the spherical drive member Sand the block-shaped drive member 5, so that they can be used selectively for different mop heads (different weights brought by different mop head types).
In this embodiment, the through hole 224 for a boss passing through on the lifting plate 22 has an axially extended hole wall 222, the hole wall 222 abuts a sidewall of the boss, and both the hole wall 222 and the sidewall are provided with a through opening 223, the drive member 5 is provided with a positioning column 52 which is insertable into the through opening 223, and when the drive member 5 is located at the end with the larger space of the gap (that is, the lifting plate 22 is located at a low position), the positioning column 52 is configured to be inserted into both through openings 223 to lock the lifting plate 22.
Moreover, the drive member 5 is provided with an elastic drive member 51 for driving the mop to move toward the end with the larger space of the gap. When the mop mops the floor, the lifting action of the lifting plate 22 is inserted and locked by the positioning column 52, and the locking state is maintained by the abutment of the elastic drive member 51, so that the lifting plate 22 can be prevented from shaking due to the displacement of the drive member 5 when the mop mops the floor.
When the mop head 2 rotates, the elastic drive member 51 is able to impart a certain reverse pressure (damping) to the drive member 5, so that the movement of the drive member 5 under the action of the centrifugal force is more uniform, which can avoid the case where the drive member 5 moves to the bottom at once.
In this embodiment, the elastic drive member 51 is a helical compression spring.
A structure of the drive member 5 is shown in
In addition, in this embodiment, as shown in
The difference between this embodiment and the embodiment one is a partial structure of a mop bucket 6 and a structure of a mop cooperatively used together.
As shown in

The cleaning member in the present disclosure may employ various cleaning components known in the existing art, including a cleaning blade, a cleaning brush 68, a cleaning rod and the like. The cleaning blade is a plate-like or block-like protrusion.
In addition, a water outlet 76 (an opening for spraying water into the mop) of the pump in this embodiment is different from that in the embodiment one. The water outlet 76 in this embodiment is only a through opening. The water outlet 76 in this embodiment is provided with a guide structure for guiding the water. A direction of spraying water is adjusted by the guide structure, so that the mop can be sprayed (cleaned) better.
The difference between this embodiment and the embodiment one is a structure of a pump 7.
As shown in
In this embodiment, the piston pump 77 includes a pump body 774 and a piston rod 771, the piston rod 771 is located at one end of the hollow pump body 774, the other end of the pump body 774 is provided with a water inlet 7741 and a water outlet 7742, the water inlet 7741 is provided with a one-way valve which is restricted to be a water inlet only, and the water outlet 7742 is provided with a one-way valve which is restricted to be a water outlet only. When the piston rod pumps the water, the clean water enters the pump body 774 from the water inlet 7741. In this case, the water outlet 7742 is blocked by the. When the piston rod 771 pressurizes water, the water in the pump body 774 is discharged from the water outlet 77421. In this case, the water inlet 7741 is blocked by the one-way valve.
More specifically, both ends of a connecting rod 772 are hinged to the piston rod 771 and an eccentric wheel 773, and the eccentric wheel 773 is connected to the drive part 71 through a gear mechanism, so that the rotation movement is converted into the linear movement by the eccentric wheel 773 mechanism.
In this embodiment, both the support part and the drive part 71 both are rotatable support column, and the gear mechanism includes a driving gear 775 located at a lower end of the support column and a driven gear 776 arranged on the periphery of the eccentric wheel 773. The driving gear 775 and the support column are formed integrally, and the driven gear 776 and the eccentric wheel 773 are formed integrally.
In this embodiment, as shown in
A mop bucket in this embodiment is divided into areas (a clean water area 61, a working area 62, and the like). Alternatively, a single bucket without being divided into the areas may be provided, and the pump 7 is arranged in the single bucket to complete the water-spray cleaning operation.
The above are merely embodiments of the present disclosure and not intended to limit the scope of the present disclosure. Any equivalent structural variations made on the basis of the Description and the drawings of the present disclosure, or direct or indirect utilization in other relevant fields all fall within the scope of the present disclosure.
