Since the mop head 4 needs to rotate at a high speed to spin water from the wiper 5 during dehydration, the planetary gear transmission needs to stop running when the mop head 4 is in the dehydration area 7, so that the mop head 4 and the inner rod 9 rotate at the same speed, as shown in fig. 18-20, in this embodiment, a clutch member 26 is arranged between the sun gear 19 and the lower cover 23, a movable tooth 27 is arranged on the clutch member 26, a fixed tooth 28 is arranged on the sun gear 19, a clutch tooth 29 is arranged on the lower cover 23, the movable tooth 27 of the clutch member 26 is movably arranged between the fixed tooth 28 and the clutch tooth 29, and the movable tooth 27 is always meshed with the fixed tooth 28 during up-down movement, so that the upper cover 22 and the clutch member 26 keep synchronously rotating, an elastic member is arranged on the clutch member 26 so that the movable tooth 27 keeps simultaneously meshed with the fixed tooth 28 and the clutch tooth 29, and in this state, due to the opposite rotation direction between the sun gear 19 and the lower cover 23, the movable tooth 27, the fixed tooth 28 and the clutch tooth 29 cooperate to fix the sun gear 19 and the lower cover 23 circumferentially, so that the planetary gear transmission cannot rotate at the same speed as the inner rod 9.

The high-speed rotation and the low-speed rotation in this embodiment are both based on the rotation speed of the inner rod 9 when the same force is applied to the outer rod 10, for example, the high-speed rotation of the mop head 4 is that the rotation speed of the mop head 4 is the same as the rotation speed of the inner rod 9 or faster than the rotation speed of the inner rod 9; and the low speed rotation of the mop head 4 is such that the rotational speed of the mop head 4 is lower than the rotational speed of the inner rod 9.

When the supporting seat 14 stretches to the lowest position, the first positioning member 32 is located at the bottom of the first lifting channel 33, so that the linkage member 46 cannot rotate relative to the fixed seat 15, the linkage groove 48 coincides with the second lifting channel 40, the second positioning member 39 is located at the bottoms of the linkage groove 48 and the second lifting channel 40, so that the body 47 and the linkage member 46 are circumferentially fixed, and the second lifting seat 31 and the linkage member 46 are circumferentially fixed.

When the second lifting seat 31 moves upward alone or the second lifting seat 31 and the body 47 move upward and the linkage member 46 is stationary, the second positioning member 39 is located at the upper end of the linkage groove 48, the first positioning member 32 is located at the lower end of the first lifting channel 33, at this time, the upper and lower ends of the linkage member 46 are fixed circumferentially relative to the fixed seat 15 and the second lifting seat 31, respectively, and the second positioning member 39 cannot rotate into the second transition groove, i.e. cannot rotate and position when the second lifting seat 31 moves upward alone.

The lifting seat 16 can only complete rotary positioning after the first lifting seat 30 and the second lifting seat 31 move upwards simultaneously, specifically, when the second lifting seat 31 moves upwards to the corresponding position, the body 47 and the linkage piece 46 are driven to move upwards, when the first positioning piece 32 is positioned at the mouth of the first transition groove, the second positioning piece 39 is also positioned at the mouth of the second transition groove, at the moment, the upper end and the lower end of the linkage piece 46 can rotate relative to the body 47 and the fixed seat 15 respectively, and simultaneously the second lifting seat 31 and the linkage piece 46 are rotated, so that the first positioning piece 32 and the second linkage piece 46 enter the first positioning groove 34 and the second positioning groove 41 respectively to be positioned simultaneously, the linkage groove 48 is staggered with the second lifting channel 40, and the lifting seat 16 is integrally positioned at a high position.

In other embodiments, as shown in fig. 14-16, the structure among the body 47, the linkage member 46 and the second lifting seat 31 may be configured such that the upper end of the linkage member 46 passes through the body 47 and then is inserted into the inner side of the second lifting seat 31, the linkage member 46 and the second lifting seat 31 are circumferentially fixed, and only can stretch up and down, the inner side of the body 47 is connected with the second lifting channel 40 through the second groove assembly, and the outer side of the body 47 is circumferentially fixed with the fixing seat 15. When the second lifting seat 31 moves upwards alone, the first positioning member 32 on the linkage member 46 is located in the first lifting channel 33, the second positioning member 39 cannot rotate into the second transition groove, and the linkage member 46 and the second lifting seat 31 can rotate simultaneously only when the first positioning member 32 moves upwards simultaneously, so that the first positioning member 32 and the second positioning member 39 enter the first positioning groove 34 and the second positioning groove 41 for positioning respectively.

In other embodiments, the linkage 46 may not be provided, so that the first lifting seat 30 and the second lifting seat 31 may be lifted, rotated, positioned and adjusted separately.

Of course, in other embodiments, the height of the lifting seat 16 or more than two lifting seats 16 may be adjusted, and the structure of the lifting seat is substantially the same as that of the two lifting seats 16 in the above embodiment, which is not described in detail.

In this embodiment, as shown in fig. 6-9, the wiping article 5 is configured as a strip-shaped mop head, one end of the strip-shaped mop head is directly fixed on the mop head 4, or one end of the strip-shaped mop head is fixed with the positioning ring, and is connected with the mop head 4 through the positioning ring, the other end of the strip-shaped mop head is a free end 49, the strip-shaped mop head is composed of a plurality of strip-shaped wiping articles, when the mop head 4 is vertically suspended, the strip-shaped mop head is in a natural sagging state, and when the mop head 4 rotates, the free end 49 of the strip-shaped mop head makes centrifugal movement to extend out from the edge of the mop head 4, so that the contact area of the wiping article 5 and the ground is larger than the contact area of the mop head 4 and the ground when the mop 1 drags the ground, and the cleaning area of the mop 1 is enlarged. The material of the strip-shaped mop head is not further limited in this embodiment, and the strip-shaped mop head can be made of superfine fiber bundles, cloth strips, cotton threads, tampons and other materials.

Preferably, the distribution form of the strip-shaped mop heads is matched with the shape of the mop head 4, for example, when the mop head 4 is round, the strip-shaped wiping objects are distributed annularly; when the mop head 4 is in the form of a polygon such as a triangle or square, the elongated wipes are arranged in a direction that forms an angle with each side of the polygon.

Because the strip-shaped mop head is provided with a plurality of strip-shaped wiping objects, the water absorption capacity of the wiping objects 5 is larger, when the wiping objects 5 are dehydrated by rotating after absorbing water, the free ends 49 of the wiping objects 5 have larger gravity, so that compared with the situation that the wiping objects 5 are dried, the force required by centrifugal motion is larger, namely, compared with the situation that the wiping objects 5 are more forceful when the mop rod 3 is pressed up and down to drive the wiping objects 5 to rotate after absorbing water, simultaneously, the free ends 49 of the wiping objects 5 can contact with the side wall of the dehydrating area 7 to generate friction and other resistance when rotating, and a user is inconvenient to use when dehydrating the wiping objects 5. Therefore, in order to save more effort when the user performs the dewatering operation, the dewatering area 7 in this embodiment is provided with the dewatering ring 8, and the dewatering ring 8 is circular overall and can rotate relative to the mop bucket 2, so that the resistance between the wiper 5 and the mop bucket 2 during rotation is reduced.

In the above embodiment, when the strip-shaped mop head is placed in the dewatering area 7, the free end 49 of the strip-shaped mop head naturally sags under the mop head 4 under the influence of gravity, when the mop head 4 rotates, the inner end of the strip-shaped mop head rotates along with the mop head 4, the free end 49 is outwards opened under the influence of centrifugal force, and the free end 49 gradually moves upwards to change the height of the strip-shaped mop head in the opening process, the free end 49 contacts with the dewatering ring 8 after centrifugal movement, the free end 49 is difficult to centrifugally open and move upwards under the obstruction of the dewatering ring 8, and the dewatering ring 8 and the mop bucket 2 are movable, so that the resistance between the free end 49 and the dewatering ring 8 drives the dewatering ring 8 to rotate along with the free end 49, and the resistance between the free end 49 and the mop bucket 2 is converted into a rotating friction force between the dewatering ring 8 and the mop bucket 2, so that the rotary dewatering of the mop head 4 is more labor-saving.

The wiper 5 becomes heavier after absorbing water, and the centrifugal force is larger when the wiper rotates, so that the wiper is easier to drive the dewatering ring 8 to rotate and lift.

Preferably, the upper and lower depth of the dewatering ring 8 is adapted to the length of the free end 49 of the strip-shaped mop head extending from the edge of the mop head 4, and the strip-shaped mop head is kept in a natural sagging state when the mop head 4 is resting on the dewatering zone 7, the lowest free end 49 is located substantially flush with the lower edge of the dewatering ring 8, and the rotational dewatering of the wipe 5 when the free end 49 is below the dewatering ring 8 is avoided, and the lowest free end 49 is centrifugally moved under and outside the dewatering ring 8, resulting in a wrapping or jamming between the free end 49 and the mop bucket 2/dewatering ring 8 in this position.

In this embodiment, when the lifting mechanism positions the mop head 4 at the low position, i.e. the cleaning area 6, the wiper 5 is immersed in water as a whole, the dewatering ring 8 is positioned above the water surface, the mop head 4 and the wiper 5 are rotated for cleaning, the free end 49 centrifugally floats upwards to the water surface, the height difference between the mop head 4 and the dewatering ring 8 is reduced, and at the moment, the lower end of the dewatering ring 8 is still higher than the free end 49.

In the above-mentioned embodiment, when the wiper 5 moves up into the dewatering area 7 after being cleaned in the cleaning area 6, if the outer end of the wiper 5 contacts the dewatering ring 8, the dewatering ring 8 can move up and comb the outer end of the wiper 5 toward the center of the mop head 4, and also can buffer the upward movement of the mop head 4, so as to prevent the mop bucket 2 from being lifted up integrally when the mop head 4 moves up.

Under this structure, when the mop head 4 rotates in the dewatering area 7, because the centrifugal movement of the free end 49 is a upward lifting manner rotation, when the free end 49 moves centrifugally to contact with the dewatering ring 8, the free end 49 drives the dewatering ring 8 to rotate, and simultaneously the upward lifting force of the free end 49 drives the dewatering ring 8 to move upwards, so that the dewatering ring 8 can be separated from the support of the mop barrel 2 in the up-down direction, the contact area between the dewatering ring 8 and the mop barrel 2 is reduced, the resistance when the dewatering ring 8 rotates is further reduced, the dewatering ring 8 and the mop barrel 2 are generally made of rigid materials such as plastics, metals and the like, and a rotating shaft for fixing the dewatering ring 8 and the mop barrel 2 is not arranged, so that the dewatering ring 8 easily generates sound due to contact or shaking between the dewatering ring 8 and the mop barrel 2 when the dewatering ring 8 rotates in situ, the lifting position is reduced after the contact area between the dewatering ring 8 and the mop barrel 2 is reduced, the sound generated by the movement of the dewatering ring 8 can be reduced, and the user experiences better feeling when the user dehydrates.

In this embodiment, the supporting seat 14 and the dewatering ring 8 are independently disposed, that is, when the mop 1 is not placed in the mop bucket 2, there is no direct connection between the supporting seat 14 and the dewatering ring 8, and the supporting seat 14 does not directly drive the dewatering ring 8 to move up and down when it stretches up and down or directly drives the supporting seat 14 to stretch up and down or rotate when the dewatering ring 8 moves up and down or rotates.

Specifically, a support 50 for supporting the dewatering ring 8 is arranged on the dewatering area 7, the support 50 limits the dewatering ring 8 to move downwards, so that the dewatering ring 8 is positioned at a position far away from the bottom of the mop barrel 2, the dewatering ring 8 is far away from the water surface, the water in the cleaning area 6 is prevented from rotating to form vortex when the dewatering ring 8 rotates, the water level at the periphery of the mop barrel 2 rises to be in contact with the wiping object 5, a first guide part 51 is arranged on the support 50, a second guide part 52 is arranged on the dewatering ring 8, the first guide part 51 has the depth in the vertical direction, the second guide part 52 is always positioned in the depth range of the first guide part 51 when the dewatering ring 8 rotates and moves upwards under the drive of the free end 49, and the first guide part 51 can always play a limiting role on the peripheral direction of the dewatering ring 8 when the dewatering ring 8 moves upwards and rotates, so that the excessive gap between the dewatering ring 8 and the mop barrel 2 is prevented from shaking and generating noise.

In this embodiment, the first guiding portion 51 is a continuous annular surface, the second guiding portion 52 is a surface of the wear-resistant member, and the second guiding portion 52 is in clearance fit with the first guiding portion 51, so that when the dewatering ring 8 rotates relative to the support 50, the first guiding portion 51 and the second guiding portion 52 are in surface contact.

In other embodiments, the first guiding portions 51 may be a plurality of cambered surfaces arranged at intervals, each cambered surface has the same center and the same radian, the second guiding portions 52 are provided as annular surfaces or annular ribs, and the second guiding portions 52 are in clearance fit or fit with each first guiding portion 51 when the dewatering ring 8 is installed.

Preferably, balls, rollers, bearings, lubricants, etc. may be provided between the first guide portion 51 and the second guide portion 52 to reduce the rotational resistance between the first guide portion 51 and the second guide portion 52, so that the two portions are more smoothly engaged.

In the above embodiment, the wipe 5 may be provided in other forms, such as cotton cloth, ultrafine fiber cloth, scouring pad, collodion, sponge, etc., which are integrally formed in a sheet shape or a strip shape and fixedly connected to the mop head 4. The length or diameter of the wipe 5 is greater than the length or diameter of the mop head 4 and the outer ends of the wipe 5 protrude from the edges of the mop head 4 when the wipe 5 is mounted on the mop head 4.

Preferably, the inner radius of the dewatering ring 8 is larger than the rotation radius of the mop head 4, so that the mop head 4 can conveniently pass through the dewatering ring 8 to enter the cleaning region 6, and collision with the dewatering ring 8 when the mop head 4 rotates is avoided; the inside radius of the dewatering ring 8 is larger than the radius of rotation of the wipe 5 when unobstructed, since the wipe 5 is flexible, its radius of rotation when obstructed is smaller than when unobstructed.

In this embodiment, the corresponding sizing of the dewatering ring 8, mop head 4 and wipe 5 facilitates the mop head 4 and wipe 5 to pass up and down through the dewatering ring 8 and provides a centrifugal space for the dewatering ring 8. In this embodiment, the diameter of the dewatering ring 8 is set to 230mm and the height is set to 90mm, and in other embodiments, the diameter of the dewatering ring 8 may be set to 200mm to 300mm and the height may be set to 80mm to 120mm.

In other embodiments, since the wiper 5 is generally made of a flexible material, the size of the wiper 5 is larger than the radius of the dewatering ring 8, but the outer end of the wiper 5 sags by gravity or deforms after contacting with the dewatering ring 8, while the lower end of the dewatering ring 8 is supported by the support 50, so that the wiper 5 can still pass through the dewatering ring 8, when the mop head 4 moves upwards into the dewatering area 7, the outer end of the wiper 5 deforms after being blocked by the dewatering ring 8, so that the outer end of the wiper 5 can contact or abut with the dewatering ring 8 and drive the dewatering ring 8 to lift upwards to a suspended state, and when the wiper 5 starts to spin-dry, the supporting force or centrifugal force between the wiper 5 and the dewatering ring 8 keeps the dewatering ring 8 to rotate in a suspended position.

In the above embodiment, the installation structure of the dewatering ring 8 may be a magnetic structure, a simple clamping structure, etc. on the basis of being placed in the mop bucket 2, a positioning structure is disposed between the dewatering ring 8 and the mop bucket 2, so that the dewatering ring 8 is positioned after moving up and down. The support 50 for supporting the dewatering ring 8 may be a leg extending from a side wall or a bottom wall of the mop bucket 2, or the support 50 may be detachably mounted at a position of the bung hole.

Preferably, a floating area 54 is arranged between the mop head 4 and the dewatering ring 8, the width of the floating area 54 is not less than 10mm, and the wiping article 5 can centrifugally move in the floating area 54 when rotating until at least part of the free end 49 contacts with the inner wall of the dewatering ring 8 and drives the dewatering ring 8 to rotate and move upwards.
