A contact piece capable of being jointed is arranged between the impeller and the spin dryer tube; when the object to be washed is washed, the contact piece does not work, so that the impeller rotates independently, and the spin dryer tube is static; when the cleaning object is spin-dried, the contact piece works, the impeller drives the contact piece to rotate, and the contact piece abuts against the spin-drying barrel under the action of rotating centrifugal force and drives the spin-drying barrel to rotate together through contact friction force. According to the cleaning machine, the internal structure of the cleaning machine is simplified, and a transmission structure of the impeller and the driving device is omitted through the arrangement of the contact piece, so that the effect of transmitting power is achieved. Therefore, the impeller drives the spin-drying barrel to rotate together through the contact piece, and the spin-drying and dewatering functions are achieved. The contact piece can also not work, and the impeller operates independently to achieve the washing function.

Description

Technical Field

[0001] The invention relates to the technical field of small cleaning equipment, in particular to a small washing and drying integrated cleaning machine. Background Art

[0002] As the name suggests, cleaning equipment is mechanical equipment designed for cleaning. Cleaning equipment plays a role in efficient cleaning. It reduces the labor cost of cleaning while also improving work efficiency and cleanliness. It is indispensable in modern society.

[0003] The cleaning machine referred to in this article mainly provides cleaning functions for small-sized items such as underwear and socks, and fruits and vegetables.

[0004] A washing machine is a cleaning appliance that uses electrical energy to create mechanical action to wash clothes.

[0005] The pulsator washing machine is another type of washing machine. The motor drives the pulsator to rotate, and the clothes are constantly tumbling up and down with the water. There are several types of washing clothes, such as single barrel, double barrel, and double barrel. Its structure is relatively simple, easy to maintain, and has a high cleaning rate, but it has a high wear rate on clothes and uses a lot of water. Nowadays, with the development of technology, new computer-controlled water flow washing machines have emerged, using large pulsators, concave pulsators, etc. The advantages are less entanglement of clothes, uniform washing, and low clothing damage rate.

[0006] Based on the disassembly, analysis and use of existing products by the inventor, some defects existing in the existing products are summarized. For example, in a pulsator washing machine, the realization of the washing and dehydration functions often requires the setting of two power systems to control the operation of the pulsator and the spin-drying drum respectively. However, this leads to a significant increase in cost on the one hand, and a more complicated structure on the other hand, occupying a large amount of internal space of the machine body; in addition, it also causes the overall size of the washing machine to become larger, occupying a large amount of indoor space, which is very unfriendly to small apartments, rental houses, etc.

[0007] In order to solve the defects of the above-mentioned double-barrel structure, the existing single-barrel structure came into being, such as patent document CN105316901B, which discloses a fully automatic pulsator washing machine, and particularly relates to a new type of split-type deceleration clutch device in a fully automatic pulsator washing machine; the split-type deceleration clutch device described in the present invention replaces the integrated deceleration clutch in the prior art. The split-type deceleration clutch described in the present invention can significantly simplify the structure of the deceleration clutch. In this patented product, its internal power structure needs to adopt an eccentric setting, and symmetrical balance cannot be guaranteed in terms of force, so the reliability and stability are relatively poor. Paragraph 0020 of its specification records that "the system is characterized in that a brake mechanism 9 is installed on the support mechanism 15, and the brake mechanism 9 is a ring-shaped brake wheel 10 (such as Figure 4), the brake arm 26 is connected to the connecting arm 18 through the brake noose 25, and the connecting arm 18 is connected to the tractor 21. In the washing state, the control system of the single-barrel direct-driven new fully automatic pulsator washing machine does not energize the tractor 21, and the brake mechanism 9 is a ring-shaped clamping brake wheel 10, and the brake wheel 10 locks the dehydration barrel 2, and the dehydration barrel does not move. Before dehydration, the control system of the single-barrel direct-driven new fully automatic pulsator washing machine energizes the tractor 21, and the tractor 21 pulls the brake arm 26 through the connecting arm 18 and the brake noose 25, and the brake arm 26 opens the brake mechanism 9, and the brake mechanism 9 releases the brake wheel 10, and the dehydration barrel is free, and the dehydration transmission system inputs power to dehydrate. After dehydration, the control system of the single-barrel direct-driven new fully automatic pulsator washing machine cuts off the power to the tractor 21, and the brake mechanism 9 holds the brake wheel 10 under the action of its own restoring force to brake the dehydration barrel 2, so that the dehydration barrel 2 stops running, and the automatic braking function of the single-barrel direct-driven new fully automatic pulsator washing machine is realized.

[0008] In the patented technology of the above-mentioned single-barrel washing machine, its working principle is to switch between the washing and dehydration functions through the action of the brake mechanism on the dehydration barrel. The inventor pointed out that this method has very serious defects. In short, during the washing process, the brake mechanism needs to continuously brake the dehydration barrel. Once the brake mechanism is released, the dehydration barrel will rotate, resulting in a significant reduction in the washing effect. However, the continuous and uninterrupted braking action is like a car moving forward without releasing the brake, which will cause great pressure on the dehydration barrel and related transmission parts. The parts are extremely easy to be damaged and deformed, resulting in a significant reduction in the life of the entire machine.

[0009] On the other hand, in existing small washing machines, both the impeller and the spin-drying tub need to rotate, and the method used is driven by a motor, which puts a heavy load on the motor and the output shaft. In order to achieve the functions of single dehydration and single spin-drying (that is, the impeller can rotate independently relative to the spin-drying tub in the washing mode), a complex transmission clutch component needs to be added, resulting in a large amount of internal space of the machine body; in addition, it will also cause the overall size of the washing machine to become larger, occupying a large amount of indoor space, which is very unfriendly to small-sized apartments, rental houses, etc. Summary of the invention

[0010] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a small washing and drying integrated cleaning machine.

[0011] The technical solution of the present invention to solve the technical problem is: a small washing and drying integrated washing machine, comprising a cleaning container, a pulsator arranged in the cleaning container and a drying bucket, wherein the pulsator is transmission-connected to a driving device;

[0012] A contact piece that can be engaged is provided between the impeller and the drying tub;

[0013] When the laundry is being washed, the contact element does not work, so the pulsator rotates alone and the spin-drying tub is stationary;

[0014] When the laundry is spun dry, the contact piece works, the impeller drives the contact piece to rotate, and the contact piece abuts against the spin-drying bucket under the action of the rotating centrifugal force and drives the spin-drying bucket to rotate together through the contact friction force.

[0015] The above technical solution is further configured to include a buoyancy anti-rotation component, wherein the density of the buoyancy anti-rotation component is less than the density of water, and under the buoyancy of water, the buoyancy anti-rotation component has at least a raised position state and a lowered position state;

[0016] The contact piece is a cleaning object;

[0017] When the laundry is washed, the buoyancy anti-rotation assembly is in a raised position, and at least part of the buoyancy anti-rotation assembly is engaged with the spin-drying tub to form a limited fit, so as to resist the contact friction force of the laundry on the spin-drying tub, so that the impeller rotates alone;

[0018] When the washings are spun dry, the buoyancy anti-rotation assembly is in a lowered position and there are washings between the spin-drying barrel and the impeller, the driving device drives the impeller to rotate, and the impeller drives the washings to rotate. Under the action of centrifugal force, the washings abut against the spin-drying barrel and drive the spin-drying barrel to rotate together through contact friction.

[0019] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly is located at the bottom of the cleaning container;

[0020] The buoyancy anti-rotation assembly includes a fixed anti-rotation base and a first anti-rotation block which is mounted on the fixed anti-rotation base and can move up and down relative to the fixed anti-rotation base; when the buoyancy anti-rotation assembly is in a raised position, the first anti-rotation block can form a limiting fit with the spin dryer barrel.

[0021] A further configuration of the above technical solution is that a coupling hole is provided on the bottom end surface of the spin-drying barrel, and the first anti-rotation block can be inserted into the coupling hole.

[0022] A further configuration of the above technical solution is that the spin-drying tub has a spin-drying groove, and the first anti-rotation block can be inserted into the spin-drying groove.

[0023] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly is located at the bottom of the cleaning container;

[0024] The buoyancy anti-rotation assembly includes a first anti-rotation floating plate, a second anti-rotation block protruding upward on the first anti-rotation floating plate, and a guide block protruding downward on the first anti-rotation floating plate, wherein the second anti-rotation block can form a limiting fit with the spin-drying tub;

[0025] The cleaning container is provided with a guide groove, and the guide block is movably arranged in the guide groove.

[0026] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly is located at the bottom of the cleaning container;

[0027] The buoyancy anti-rotation assembly comprises a first guide seat protruding upward from the cleaning container, a second guide seat protruding downward from the spin-drying bucket, and a second anti-rotation floating plate sleeved on the first guide seat;

[0028] When the laundry is washed, the second anti-rotation floating plate rises, so that the second anti-rotation floating plate is simultaneously sleeved on the first guide seat and the second guide seat to limit the spin-drying barrel;

[0029] When the laundry is being spun dry, the second anti-rotation floating plate is lowered, so that the second anti-rotation floating plate is staggered from the second guide seat to release the spin-drying barrel.

[0030] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly is located on the side wall of the cleaning container;

[0031] The buoyancy anti-rotation assembly includes a guide column that is gradually inclined inward from bottom to top, a third anti-rotation block that is sleeved on the guide column and can move up and down along the guide column, and the spin dryer barrel has a spin dryer groove. When the buoyancy anti-rotation assembly is in a raised position, the third anti-rotation block can be inserted into the spin dryer groove.

[0032] A further configuration of the above technical solution is that the third anti-rotation block is provided with a protruding portion and a recessed portion;

[0033] The spin drying barrel has structural ribs, and the spin drying grooves are formed between adjacent structural ribs. The structural ribs can be inserted into the recessed parts, and the protruding parts can be inserted into the spin drying grooves.

[0034] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly is located on the side wall of the cleaning container;

[0035] The buoyancy anti-rotation assembly comprises a bracket, an anti-rotation rod hinged on the bracket, and a float acting on the anti-rotation rod;

[0036] The spin drying tub has a spin drying groove, and the anti-rotation rod can be inserted into the spin drying groove to limit the rotation of the spin drying tub.

[0037] In some preferred embodiments of the present invention, the buoyancy anti-rotation assembly includes a fourth anti-rotation block, an anti-rotation portion arranged on the spin-drying bucket and forming a limiting fit with the fourth anti-rotation block, and a drainage pipeline arranged on the cleaning container;

[0038] The fourth anti-rotation block is inserted into the drainage pipeline and forms a clearance fit, so that the fourth anti-rotation block can move up and down along the drainage pipeline.

[0039] A further configuration of the above technical solution is that the fourth anti-rotation block is provided with a vertical through hole, and the side wall of the fourth anti-rotation block is provided with a plurality of water holes.

[0040] A further configuration of the above technical solution is that the stop portion is a stop hole, and the outer wall of the fourth stop block protrudes outward to form a limiting rib, so that the maximum size of the fourth stop block is respectively larger than the aperture of the stop hole and the size of the drainage pipe.

[0041] The beneficial effects of the present invention are:

[0042] 1. The internal structure of the washing machine is simplified. Through the setting of the contact piece, the transmission structure of the impeller and the driving device is eliminated to play the role of transmitting power. Therefore, the impeller drives the spin-drying bucket to rotate together through the contact piece to realize the spin-drying and dehydrating function; the contact piece can also be not working, and the impeller can run alone to realize the washing function.

[0043] Second, by setting the buoyancy anti-rotation component, it floats up in the washing mode to limit the rotation of the spin dryer tub, and avoids the spin dryer tub in the spin-drying mode so that the spin dryer tub can be rotated to achieve a normal spin-drying and dehydration effect.

[0044] 3. The rotation of the spin dryer is completely independent of the direct action of the driving device, but relies on the contact friction of the contact parts (such as clothes, fruits and vegetables, etc.), which makes the transmission structure simpler, reduces the failure rate, and does not occupy any internal space, making the whole machine smaller. It can also reduce the cost of production and manufacturing, making the product more competitive in the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] Embodiment 1

[0063] Reference Figures 1 to 13 A small washing and drying machine includes a cleaning container 1, a pulsator 2 and a spin-drying bucket 3 arranged in the cleaning container 1, wherein the pulsator 2 is transmission-connected to a driving device 4;

[0064] A contact member 5 that can be engaged is provided between the pulsator 2 and the drying tub 3;

[0065] When the laundry is being washed, the contact member 5 does not work, so the pulsator 2 rotates alone, and the spin-drying tub 3 is stationary;

[0066] When the laundry is spun dry, the contact member 5 works, and the impeller 2 drives the contact member 5 to rotate. The contact member 5 abuts against the spin-drying tub 3 under the action of the rotating centrifugal force and drives the spin-drying tub 3 to rotate together through the contact friction force.

[0067] The above content is the basic solution of the present invention. Compared with the prior art, it adds a contact member 5 to play the role of transmitting power. Therefore, the pulsator 2 drives the spin-drying tub 3 to rotate together through the contact member 5 to achieve the spin-drying and dehydrating function; the contact member 5 may not work, and the pulsator 2 can operate alone to achieve the washing function.

[0068] Regarding the basic scheme, it is further preferably configured to also include a buoyancy anti-rotation component 6, the density of the buoyancy anti-rotation component 6 is less than the density of water, and under the buoyancy of water, the buoyancy anti-rotation component 6 has at least a raised position state and a lowered position state. Among them, the contact member 5 is a cleaning object, and of course it can also be a silicone pad, a plastic part, etc., and its specific type is not specifically limited here; among them, this cleaning object can be underwear and socks, or fruits and vegetables, or small-sized rough processed parts and other materials, as long as it has a surface roughness and can generate sufficient friction when in contact, its specific type is not specifically limited here. The usage mechanism of this preferred configuration is:

[0069] When the laundry is washed, the buoyancy anti-rotation assembly 6 is in a raised position, and the buoyancy anti-rotation assembly 6 is at least partially engaged with the spin-drying tub 3 to form a limit fit to resist the contact friction of the laundry on the spin-drying tub 3 (and can also resist the force of the water flow on the spin-drying tub 3, etc.), so that the impeller 2 rotates alone;

[0070] When the washings are spun dry, the buoyancy anti-rotation assembly 6 is in a lowered position and there is washings between the spin-drying tub 3 and the impeller 2, the driving device 4 drives the impeller 2 to rotate, and the impeller 2 drives the washings to rotate, and the washings abut against the spin-drying tub 3 under the action of centrifugal force and drive the spin-drying tub 3 to rotate together through contact friction.

[0071] Preferably, the driving device 4 is a motor 401, the impeller 2 is directly connected to the output shaft 402 of the motor 401 and forms a transmission fit, and the spin dryer barrel 3 is connected to the output shaft 402 of the motor 401 through a bearing sleeve. Under the action of the bearing, the spin dryer barrel 3 can be installed and supported, and the output shaft 402 of the motor 401 can be disengaged from the spin dryer barrel 3 when rotating.

[0072] Embodiment 2

[0073] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, a preferred embodiment is provided, which does not limit the present invention in any way. The specific embodiments are as follows:

[0074] Reference Figure 2 to Figure 5 , the buoyancy anti-rotation assembly 6 is located at the bottom of the cleaning container 1;

[0075] The buoyancy anti-rotation assembly 6 includes a fixed anti-rotation base 611, and a first anti-rotation block 612 which is mounted on the fixed anti-rotation base 611 and can move up and down relative to the fixed anti-rotation base 611; when the buoyancy anti-rotation assembly 6 is in a raised position, the first anti-rotation block 612 can form a limiting fit with the spin dryer tub 3.

[0076] There are two main structures of the first anti-rotation block 612 limiting the spin-drying tub 3, specifically:

[0077] 1. The spin drying tub 3 is structurally processed, and a coupling hole 301 is provided on the bottom end surface of the spin drying tub 3 (the coupling hole 301 may also be in the form of a groove or a rib), and the first anti-rotation block 612 is arranged at an inner position so as to be inserted into the coupling hole 301. Of course, the positions of the first anti-rotation block 612 and the coupling hole 301 can be interchanged, and the working method is the same, which will not be described in detail here.

[0078] Second, the structure of the spin-drying tub 3 is not processed, and the structural characteristics of the spin-drying tub 3 are utilized, that is, the spin-drying tub 3 has a spin-drying groove 302, and the first anti-rotation block 612 is arranged at an outer position so that it can be inserted into the spin-drying groove 302.

[0079] Embodiment 3

[0080] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, a preferred solution different from the above-mentioned embodiment is provided, which does not limit the present invention in any way. The specific solutions are as follows:

[0081] Reference Figure 6-7 , the buoyancy anti-rotation assembly 6 is located at the bottom of the cleaning container 1;

[0082] The buoyancy anti-rotation assembly 6 includes a first anti-rotation floating plate 621, a second anti-rotation block 622 protruding upward on the first anti-rotation floating plate 621, and a guide block 623 protruding downward on the first anti-rotation floating plate 621. The second anti-rotation block 622 can form a limiting fit with the engaging hole 301 on the spin dryer barrel 3; a guide groove 101 is provided on the cleaning container 1, and the guide block 623 is movably arranged in the guide groove 101, so that the first anti-rotation floating plate 621 can float in a specific direction under the action of buoyancy, and can also fall back in a specific direction after the water is drained.

[0083] Embodiment 4

[0084] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, a preferred solution different from the above-mentioned embodiment is provided, which does not limit the present invention in any way. The specific solutions are as follows:

[0085] Reference Figure 8-Figure 9 , the buoyancy anti-rotation component 6 is located at the bottom of the cleaning container 1; the buoyancy anti-rotation component 6 includes a first guide seat 631 protruding upward from the cleaning container 1, a second guide seat 632 protruding downward from the spin-drying barrel 3, and a second anti-rotation floating plate 633 sleeved on the first guide seat 631. Different from the aforementioned embodiment, this embodiment cancels the structure of the anti-rotation block, and instead directly integrates the anti-rotation function on the second anti-rotation floating plate 633, which plays both a lifting and lowering role and an anti-rotation role. Preferably, the second anti-rotation floating plate 633 adopts a non-circular polygonal shape to suppress movement in the rotation direction. The specific working principle of this embodiment is as follows:

[0086] When washing the laundry, the second anti-rotation floating plate 633 rises, so that the second anti-rotation floating plate 633 is simultaneously sleeved on the first guide seat 631 and the second guide seat 632 to limit the spin-drying tub 3;

[0087] When the laundry is being spun dry, the second anti-rotation floating plate 633 is lowered, so that the second anti-rotation floating plate 633 is staggered from the second guide seat 632 to release the spin-drying tub 3.

[0088] Embodiment 5

[0089] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, a preferred solution different from the above-mentioned embodiment is provided, which does not limit the present invention in any way. The specific solutions are as follows:

[0090] Reference Figure 10-11 , the aforementioned embodiment sets the buoyancy anti-rotation component 6 at the bottom, while this embodiment changes the setting position, and sets the buoyancy anti-rotation component 6 on the side wall of the cleaning container 1. Specifically, the buoyancy anti-rotation component 6 includes a guide column 641 that is gradually inclined inward from bottom to top, a third anti-rotation block 642 that is sleeved on the guide column 641 and can move up and down along the guide column 641, and the spin-drying barrel 3 has a spin-drying groove 302. Among them, the setting method of the guide column 641 is more critical, which can enable the third anti-rotation block 642 to move inward while being lifted by buoyancy, that is, to achieve multi-directional movement. Therefore, the working principle of this embodiment is:

[0091] When the buoyancy anti-rotation assembly 6 (the third anti-rotation block 642 ) is in the raised position, the third anti-rotation block 642 moves upward and inward to be inserted into the spin-drying tank 302 .

[0092] When the buoyancy stop assembly 6 (third stop block 642) is in the descending position, the third stop block 642 moves downward and outward, so that the third stop block 642 is offset from the spin-drying tub 3, eliminating the limit.

[0093] A further setting of the above technical solution is that the third stop block 642 is provided with a protrusion 6421 and a recessed portion 6422; the spin dryer barrel 3 has structural ribs 303, and the spin dryer groove 302 is formed between adjacent structural ribs 303, and when the buoyancy stop assembly 6 (the third stop block 642) is in a raised position, the structural ribs 303 can be inserted into the recessed portion 6422, and the protrusion 6421 can be inserted into the spin dryer groove 302.

[0094] Embodiment 6

[0095] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, a preferred solution different from the above-mentioned embodiment is provided, which does not limit the present invention in any way. The specific solutions are as follows:

[0096] Reference Figure 12-13 , similar to the fifth embodiment, this embodiment also sets the buoyancy anti-rotation component 6 on the side wall of the cleaning container 1;

[0097] The buoyancy anti-rotation assembly 6 includes a bracket 651, a anti-rotation rod 652 hinged on the bracket 651, and a float 653 acting on the anti-rotation rod 652; the spin dryer 3 has a spin dryer groove 302, and the anti-rotation rod 652 can be inserted into the spin dryer groove 302 to limit the rotation of the spin dryer 3.

[0098] During use, when the anti-rotation rod 652 floats up driven by the float 653, it can be stuck into the spin-drying tank 302 to limit the rotation of the spin-drying barrel 3, so that the impeller 2 rotates alone; after the anti-rotation rod 652 descends, it can be offset from the spin-drying barrel 3, thereby releasing the spin-drying barrel 3 to reset it, and the impeller 2 drives the washing objects to rotate. The washing objects abut against the spin-drying barrel 3 under the action of centrifugal force and drive the spin-drying barrel 3 to rotate together through contact friction.

[0099] In the above, the bracket 651 can be integrally formed with the cleaning container 1, or can be separately formed and then assembled into one.

[0100] Embodiment 7

[0101] The buoyancy anti-rotation assembly 6 proposed in the first embodiment refers to various structural modes. Here, another preferred solution different from the above-mentioned embodiment is provided, which does not limit the present invention in any way. The specific details are as follows:

[0102] The buoyancy stop assembly 6 includes a fourth stop block 661, a stop portion 662 arranged on the spin dryer tub 3 and forming a limiting fit with the fourth stop block 661, and a drainage pipe 663 arranged on the cleaning container 1; the fourth stop block 661 is inserted into the drainage pipe 663 and forms a clearance fit, so that the fourth stop block 661 can move up and down along the drainage pipe 663.

[0103] In the above, the preferred form of the drainage pipe 663 referred to is that it is made of plastic material and is integrally formed with the cleaning container 1 through an injection molding process, so that the shape of the drainage pipe 663 is stable and unchanged. On the other hand, a hose can also be connected to the end of the drainage pipe 663 to drain water to the outside.

[0104] During washing, when the speed increases, water will be thrown to the side wall of the spin-drying tub 3, which may cause the buoyancy anti-rotation component 6 to fall down and lose its function. Therefore, the structure of this embodiment can solve the above-mentioned defects.

[0105] The fourth anti-rotation block 661 floats up and is stuck with the spin-drying tub 3. During washing, there is water between the fourth anti-rotation block 661 and the spin-drying tub 3. At the same time, the drainage pipe 663 is at a low position, so there must be water. The cooperation of the two prevents the fourth anti-rotation block 661 from falling during washing. During dehydration and drying, the water needs to be drained out through the drainage pipe 663 first. With the help of the flow force of the water, the fourth anti-rotation block 661 can be always adsorbed on the bottom of the spin-drying tub 3 (drainage pipe 663) to ensure that it releases the spin-drying tub 3.

[0106] A further configuration of the above technical solution is that the fourth stop block 661 is provided with a vertical through hole 6611, and the side wall of the fourth stop block 661 is provided with a plurality of water holes 6612. Through the provision of the through hole 6611 and the water holes 6612, the negative pressure between the side of the fourth stop block 661 and the cleaning container 1 etc. (when there is water on the surface and the distance between the two objects is small, adsorption force will also be generated) can be eliminated to the greatest extent to ensure that they will not be adsorbed, thereby making the floating descent smoother and unobstructed. In addition, the water can be discharged through the through hole 6611 and the water holes 6612.

[0107] Preferably, the stopper 662 is a stopper hole, and the outer wall of the fourth stopper 661 protrudes outward to form a limiting rib 6613, so that the size of the fourth stopper 661 at the largest point is respectively larger than the aperture of the stopper hole and the size of the drainage pipe 663.
