Description

Technical Field

[0001] The invention relates to the field of cleaning, and in particular to a cleaning device. Background Art

[0002] Cleaning equipment is an essential tool in people's daily life, and its types are also rich and varied, mainly including: mops, brooms, vacuum cleaners, sweeping robots, etc. In purchasing choices, people usually choose the required cleaning equipment based on cleaning needs and prices, but consumers will face a common problem: mops, brooms and vacuum cleaners cannot replace each other, and sweeping robots are too expensive to be used as an equivalent substitute for mops or brooms.

[0003] In order to improve the above technical problems, there are some cleaning equipment products in the market that integrate sweeping and mopping functions. The main working principle is to directly use a motor-driven roller brush and set up a garbage collection area at the same time, trying to use the rolling action of the roller brush on the ground to carry the garbage and send the garbage into the garbage collection area at the same time, so as to achieve the cleaning of the ground. However, this method will face many technical problems when facing the actual ground cleaning application with various cleaning environments, mainly including: 1. Due to the material limitation of the roller brush itself, it is difficult to ensure that the dust or sewage on the ground is sent to the garbage collection area at the same time; 2. The sewage absorbed by the roller brush itself is difficult to be collected into the garbage collection area, resulting in the gradual ineffectiveness of the cleaning effect of the roller brush, and at the same time causing the problem of water accumulation on the ground; 3. The dry and wet garbage collected in the garbage collection area is in a mixed closed state. After long-term use, the garbage collection area is easy to stink, and the user experience is poor; and because the collection entrance of the garbage collection area needs to be set for the roller brush to achieve the function of directional collection, when the user pulls the cleaning equipment as a whole, it will cause the garbage in the garbage collection area to overflow.

[0004] To this end, the applicant hopes to make targeted improvements to the above technical problems so that they can be more easily accepted by the general public and bring a good cleaning experience. Summary of the invention

[0005] The object of the present invention is to provide a cleaning device which can significantly avoid or reduce the leakage of garbage and effectively improve the cleaning effect of the combined sweeping and mopping function through the specific design combination of a roller brush and a cleaning guide path.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] A cleaning device comprises a roller brush mounted on a shell and capable of rolling contact with the ground, wherein a garbage collection area is integrally or separately provided in the shell, and the garbage collection area is provided with a collection inlet corresponding to the roller brush, and garbage picked up by the rolling contact is collected into the garbage collection area under the rotation of the roller brush; wherein the shell is provided with one or more scraping guides connected to the collection inlet, and the scraping guides are in flexible pressure contact with the roller brush or the ground, and are used for scraping away residual garbage absorbed by the roller brush itself or residual garbage on the ground and transferring them to the garbage collection area, so as to reduce or avoid missing garbage.

[0008] As a preferred technical solution, the roller brush and the shell cooperate with each other to form a roller brush scraping guide connected to the collection inlet, which is used to scrape off the residual garbage absorbed by the roller brush itself and transfer it to the garbage collection area; wherein the roller brush scraping guide includes a roller brush scraper located on the shell and in flexible pressure contact with the roller brush, and the roller brush scraper is provided with a liquid storage space, which is connected to the garbage collection area through a drainage path.

[0009] As an optimal technical solution, the roller brush scraper is installed separately from the shell, and the distance between the roller brush scraper and the roller brush can be adjusted through lifting and lowering movements, thereby realizing the adjustment of the flexible pressure contact effect between the roller brush scraper and the roller brush to meet the cleaning requirements of different cleaning conditions; wherein, during cleaning conditions, increasing the distance between the roller brush scraper and the roller brush is beneficial to the cleaning effect of the roller brush on the ground, and during mopping conditions, reducing the distance between the roller brush scraper and the roller brush is beneficial to the mopping effect on the ground.

[0010] As an optimal technical solution, the liquid storage space includes a liquid storage drainage groove connected to the drainage path, and a plurality of scraping holes are provided on the liquid storage drainage groove. Through the flexible pressure contact between the roller brush scraper and the roller brush, each of the scraping holes scrapes away the residual garbage absorbed by the roller brush itself and transfers it to the liquid storage drainage groove; or the liquid storage space includes a liquid storage cavity plate having a liquid storage cavity, and a plurality of scraping holes are provided on the liquid storage cavity plate. Through the flexible pressure contact between the roller brush scraper and the roller brush, each of the scraping holes scrapes away the residual garbage absorbed by the roller brush itself and transfers it to the water storage cavity plate.

[0011] As a preferred technical solution, the roller brush and the shell cooperate to form a ground scraping guide connected to the collection inlet, which is used to scrape residual garbage on the ground and transfer it to the garbage collection area through the rotational movement of the roller brush; wherein the ground scraping guide includes a ground scraping strip and a guide surface respectively located on the shell, the ground scraping strip is in flexible pressure contact with the ground, and the guide surface is connected to the collection inlet.

[0012] As a preferred technical solution, the floor scraper extends obliquely along the direction of the roller brush, and the floor scraper is installed on the guide surface in a relatively swingable manner to adjust the resistance of the floor scraper in flexible pressure contact with the ground.

[0013] As an optimal technical solution, a water collecting platform is formed between the two ends of the guide surface and the ground scraper, and protrusions are respectively provided at both ends of the ground scraper to form a concave reflux collection area located in the middle, and the garbage in the concave reflux collection area is transferred to the garbage collection area through the rotational movement of the roller brush.

[0014] As a preferred technical solution, the housing is provided with a roller brush scraping guide and a ground scraping guide connected to the collection inlet and located at the upper and lower parts respectively; wherein,

[0015] The roller brush scraping guide is in flexible pressure contact with the roller brush, and is used to scrape off the residual garbage absorbed by the roller brush itself or the residual garbage on the ground and transfer it to the garbage collection area; the ground scraping guide is in pressure contact with the ground, and is used to scrape off the residual garbage on the ground and transfer it to the garbage collection area;

[0016] When the roller brush is rotating, a directional closed-loop cleaning path is formed between the ground, the roller brush and the garbage collection area through the linked scraping of the roller brush scraping guide and the ground scraping guide, so as to reduce or avoid missing garbage.

[0017] As an optimal technical solution, the bottom of the shell is provided with a receiving guide groove connected to the scraping guide, which is used to receive the droplets dropped when the roller brush rotates, and transfer the liquid in the receiving guide groove to the garbage collection area through the scraping guide.

[0018] As a preferred technical solution, the roller brush includes a driving roller that is driven by a driver and relatively rotatably installed on the shell, and the outer periphery of the driving roller is coated with a flexible roller brush for flexible contact with the ground, wherein the material of the flexible roller brush includes at least two cleaning fibers with unequal water absorption rates, the cleaning fibers with high water absorption rates are beneficial for removing liquid waste from the ground, and the cleaning fibers with low water absorption rates are beneficial for removing solid waste from the ground.

[0019] The water absorption rate herein refers to the ratio of the water that can be absorbed by the cleaning fiber per unit mass or volume to the volume or mass of the cleaning fiber itself, which is common knowledge in the art.

[0020] The advantages and beneficial effects of the present invention are as follows: the present invention first utilizes the rolling contact between the roller brush and the ground, so that the garbage on the ground is sucked by the negative pressure and carried by the roller brush in a rotating motion state, and at the same time, the centrifugal force effect generated when the roller brush rotates will transfer it to the garbage collection area corresponding to the roller brush. However, the directional garbage collection function of the centrifugal force effect is poor, which will lead to more garbage omissions. For this reason, the present invention also creatively proposes to set a scraping guide connected to the collection inlet, and the scraping guide is in flexible pressure contact with the roller brush or the ground, which is used to scrape the residual garbage absorbed by the roller brush itself or the residual garbage on the ground and transfer it to the garbage collection area, which can significantly reduce or avoid garbage omissions, effectively improve the cleaning effect of the composite sweeping and mopping function, and finally make it easy to be widely accepted by the general consumers and bring a good cleaning experience; the present invention further preferably proposes to set a roller brush scraping guide and a ground scraping guide respectively at the upper and lower sides, and when the roller brush is rotating, the roller brush scraping guide and the ground scraping guide are linked to scrape and form a directional closed-loop cleaning path between the ground, the roller brush and the garbage collection area, which can minimize or avoid garbage omissions.

DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0038] Example 1: Please refer to Figures 1 to 13As shown, a cleaning device 1 includes a roller brush 2 installed on a shell and capable of rolling contact with the ground, the shell includes a mounting shell 11 for mounting the roller brush 2, the mounting shell 11 is mounted as a whole by an upper mounting shell 11a and a lower mounting shell 11b, the lower mounting shell 11b realizes displacement movement on the ground through a main roller assembly 17a and a secondary roller assembly 17b, so as to avoid or reduce frictional contact between the roller brush 2 and the ground; the mounting shell 11 is mounted and connected as a whole with a handle 13 through a twisting head 12; a garbage collection area is integrally or separately provided in the mounting shell 11, in this embodiment, the garbage collection area adopts a garbage collection box 3, which can be directly engaged with the mounting shell 11, so as to facilitate the user's actual operation such as disassembly, garbage cleaning and cleaning of the garbage box; the garbage collection box 3 is provided with a collection inlet 31 corresponding to the roller brush 2, and the garbage brought up by rolling contact is collected into the garbage collection box 3 under the rotation of the roller brush 2;

[0039] Preferably, in this embodiment, the roller brush 2 includes a driving roller 2a driven by a driver and relatively rotatably mounted on the mounting housing 11, and the outer periphery of the driving roller 2a is coated with a flexible roller brush 2b for flexible contact with the ground. Specifically, in this embodiment, the driving roller 21 is driven by a driver 7 composed of a motor 71 and a pulley 72, and both ends of the driving roller 2a are detachably mounted on the pulley output end and the mounting housing 11, respectively. The specific mounting structure can adopt conventional technical means in the art;

[0040] Among them, the material of the flexible roller brush 2b includes at least two cleaning fibers with unequal water absorption rates, the cleaning fibers with high water absorption rates are mainly used to remove liquid garbage on the ground, and the cleaning fibers with low water absorption rates are mainly used to remove solid garbage on the ground; specifically, in the implementation and application, the cleaning fibers with high water absorption rates can select cotton fiber couples or fibers with similar water absorption rates, and their water absorption rates are usually 1.5-3, and the more preferred water absorption rate is 1.5-2; the cleaning fibers with low water absorption rates can select polyester fibers, and their water absorption rates are usually not higher than 1.5; in order to further achieve a better cleaning effect, in this embodiment, the fluff of the cleaning fibers with low water absorption rates is longer than the fluff of the cleaning fibers with low water absorption rates, and the length difference can be set to 1-2mm;

[0041] In order to facilitate meeting the cleaning needs of the floor with garbage in various states, in this embodiment, the cleaning fibers with high water absorption rate and the cleaning fibers with low water absorption rate are distributed in an alternating spiral shape on the driving roller 2a; the distribution area range of the cleaning fibers with high water absorption rate and the cleaning fibers with low water absorption rate on the flexible roller brush 2b is 1:0.5-2.5, and the specific area ratio can be selected according to the specific application cleaning needs, which is not a limitation of this embodiment; when in use, the water in the fluff of each cleaning fiber on the roller brush 2 can be fully thrown out by the centrifugal force, and it is not easy to leave residual water; at the same time, after cleaning, the cleaning fiber fluff on the roller brush 2 can also be quickly dried, and bacteria will not grow due to excessive moisture;

[0042] The mounting housing 11 is provided with one or more scraping guides connected to the collection inlet 31, and the scraping guides are in flexible pressure contact with the roller brush 2 or the ground, and are used to scrape the residual garbage absorbed by the roller brush 2 itself or the residual garbage on the ground and transfer them to the garbage collection box 3, so as to reduce or avoid garbage leakage;

[0043] Preferably, in this embodiment, the mounting shell 11 is provided with a roller brush scraping guide 4 and a ground scraping guide 5 connected to the collection inlet 31 and respectively located at the upper and lower parts; wherein the roller brush scraping guide 4 is in flexible pressure contact with the roller brush 2, and is used to scrape off the residual garbage absorbed by the roller brush 2 itself or the residual garbage on the ground and transfer it to the garbage collection box 3; the ground scraping guide 5 is in pressure contact with the ground, and is used to scrape off the residual garbage on the ground and transfer it to the garbage collection box 3; when the roller brush 2 is rotating, the roller brush scraping guide 4 and the ground scraping guide 5 are linked to scrape off, so as to form a directional closed-loop cleaning path between the ground, the roller brush 2 and the garbage collection box 3, so as to minimize or avoid garbage omission;

[0044] Specifically preferably, in this embodiment, the roller brush 2 and the mounting shell 11 are matched to form a roller brush scraping guide 4 connected to the collection inlet 31, which is used to scrape off the residual garbage absorbed by the roller brush 2 itself and transfer it to the garbage collection box 3; wherein the roller brush scraping guide 4 includes a roller brush scraper 41 located on the mounting shell 11 and in flexible pressure contact with the roller brush 2, and the roller brush scraper 41 is provided with a liquid storage space, which is connected to the garbage collection box 3 through a drainage path. In specific implementation, the roller brush scraper 41 is in an arc shape, and the roller brush scraper 41 can be connected to the mounting shell 11 as a whole or in a split installation connection, which is not particularly limited in this embodiment;

[0045] Preferably, the roller brush scraper 41 and the cleaning fibers on the roller brush 2 are in an interference state. Specifically, the interference between the roller brush scraper 41 and the short cleaning fiber fluff is 0.5-2mm. When the interference is too large, the cleaning fiber fluff of the roller brush 2 is easily agglomerated, and the fluffy state of the cleaning fibers of the roller brush 2 cannot be ensured, resulting in a gap between the cleaning fibers and the ground, and the garbage on the ground cannot be effectively cleaned. When the interference is too small, the contact between the roller brush scraper 41 and the cleaning fibers of the roller brush 2 is too small, and the scraping effect is low.

[0046] The liquid storage space includes a liquid storage drainage groove 42 connected to the drainage path, and a plurality of scraping holes 43 are provided on the liquid storage drainage groove 42. Through the flexible pressure contact between the roller brush scraper 41 and the roller brush 2, each scraping hole scrapes the residual garbage absorbed by the roller brush 2 and transfers it to the liquid storage drainage groove 42; in other embodiments, the liquid storage space may also include a liquid storage cavity plate (not shown) having a liquid storage cavity, and a plurality of scraping holes 43 are provided on the liquid storage cavity plate. Through the flexible pressure contact between the roller brush scraper 41 and the roller brush 2, each scraping hole 43 scrapes the residual garbage absorbed by the roller brush 2 and transfers it to the water storage cavity plate. The structural design of the liquid storage cavity plate can have a better liquid storage effect and avoid water leakage. However, this will also cause liquid garbage to remain on the water storage cavity plate. Those skilled in the art can select a specific implementation plan according to actual needs.

[0047] In the specific implementation of this embodiment, the scraping hole 43 is arranged corresponding to the roller brush 2, and the diameter range of the scraping hole 43 can be set to 0.5-2mm, and its shape is inclined downward to ensure that the water flowing into the scraping hole 43 is not easy to return; the drainage path includes a drainage groove 44 located in the mounting shell 11, and the inlet of the drainage groove 44 is connected to one side or both sides of the liquid storage drainage groove 42, and its outlet is connected to the garbage collection box 3; further preferably, a plurality of scraper ribs are distributed on the surface of the roller brush scraper 41 facing the roller brush 2, which can further improve the scraping efficiency and ensure the fluffy state of the cleaning fiber of the roller brush 2. The height of the scraper ribs can be set to 0.2-1mm;

[0048] Specifically preferably, in the present embodiment, the roller brush 2 and the mounting shell 11 are matched to form a floor scraping guide 5 connected to the collection inlet 31, which is used to scrape the residual garbage on the ground and transfer it to the garbage collection box 3 through the rotational movement of the roller brush 2; wherein the floor scraping guide 5 includes a floor scraping strip 51 and a guide surface 52 respectively located on the mounting shell 11, the floor scraping strip 51 is in flexible pressure contact with the ground, and the guide surface 52 is connected to the collection inlet 31; the floor scraping strip 51 extends obliquely along the direction of the roller brush 2, and during implementation, the floor scraping strip 51 can be made of a rubber scraping strip, and its front end is designed to be obliquely extended along the direction of the roller brush 2. The ground scraping strip 51 has a Shore A hardness of 40-80 degrees, preferably 45-70 degrees, which can ensure that when the front end of the ground scraping strip 51 contacts the ground, its sharp wedge-shaped part is appropriately deformed, so that its flexible contact with the ground is tighter. After the roller brush 2 sweeps the garbage on the ground, the sewage water film missed on the ground can be pushed forward into a ball shape, and the sewage water film missed on the ground can be collected into the garbage collection box 3 through the rotation of the roller brush 2 and the guidance of the guide surface 52. There will be no residual water on the ground after the cleaning is completed, which significantly improves the sewage collection rate, thereby achieving the scraping effect of the missed garbage on the ground;

[0049] Considering that when the user operates the cleaning device to push forward, if the floor scraper 51 cannot swing relative to the guide surface 52, due to the large force-bearing surface, especially the water film tension formed by the sewage on the ground, the force center of the floor scraper 51 is located in the front part of the cleaning device 1, and it is more difficult for the user to push the cleaning device 1 forward. In order to overcome the large forward resistance, the cleaning device 1 will show an unobvious up and down forward movement, which leads to a poor scraping effect of the floor scraper 51 and a thick residual water film. Therefore, this embodiment also proposes: the floor scraper 51 can be relatively swung and installed on the guide surface 5 2, which is used to adjust the resistance of the floor scraper 51 to the flexible pressure contact with the ground, and the resistance is smaller; through this structure, when the cleaning device 1 is pushed forward for cleaning, the lower edge of the floor scraper 51 in contact with the ground will be deformed backward by force, and when the cleaning device 1 is pulled backward for cleaning, the lower edge of the floor scraper 51 in contact with the ground will be deformed forward by force. Under the limiting effect of the guide surface 52, the floor scraper 51 will still face a certain pressure, which is convenient for quickly and flexibly squeezing the sewage water film for cleaning, and the scraping surface is sufficient, which significantly reduces the problem of liquid or water residue on the ground, has a good scraping effect, and is easy and convenient for users to clean;

[0050] In the present embodiment, a water collecting platform 53 is formed between the two ends of the guide surface 52 and the floor scraper 51. In the process of setting the flexible roller brush 2b, considering the installation structure requirements at both ends of the driving roller 2a, the cleaning fiber fluff of the flexible roller brush 2b cannot fill both ends, because too much cleaning fiber fluff will cause the two sides of the cleaning device 1 to rotate and entangle. However, this will cause the water released by the roller brush 2 during the rotation and centrifugation process to be less likely to be pushed by the cleaning fiber fluff of the roller brush 2 to enter the collection inlet 31 of the garbage collection box 3 at the positions on both sides, but will flow back from the two ends of the water collecting platform 53, resulting in the problem of garbage leakage. For this reason, preferably, in the present embodiment, the floor scraper 51 The two ends are provided with protrusions 54, respectively, forming a concave reflux collection area 55 located in the middle. Through the rotation of the roller brush 2, various solid or liquid garbage in the concave reflux collection area 55 is thrown (transferred) into the garbage collection box 3; the guide surface 52 of this embodiment can also be called a centrifugal decontamination surface, which is arranged opposite to the roller brush 2. Since the protrusions 54 are arranged at both ends of the floor scraper 51, a concave reflux collection area 55 with high sides and low middle is formed. When working, the sewage at both ends of the water collection platform 53 is gathered to the middle through the concave reflux collection area 55, and is cleaned again by the roller brush 2, thereby avoiding the formation of two sewage marks on both sides of the cleaning device 1, and improving the cleaning effect;

[0051] In actual deep application, the applicant found that when the cleaning device is used to clean a wet floor with liquid garbage, even if the roller brush 2 squeezes out water through the flexible pressure contact between the roller brush scraper 41, it is inevitable that sewage will flow downward and drip, causing sewage leakage; for this reason, preferably, in this embodiment, a receiving guide groove 18 connected to the guide surface 52 is provided at the bottom of the lower mounting shell 11b, and the receiving guide groove 18 is located below the roller brush 2 and connected to both sides of the guide surface 52 to form a closed receiving guide groove structure, which is used to receive the droplets dropped when the roller brush 2 rotates (including the droplets dropped when the roller brush scrapes off the guide 4 and contacts the roller brush 2 with flexible pressure), and the sewage in the receiving guide groove is thrown into the garbage collection box 3 again through the guide surface 52 of the ground scraping guide 5;

[0052] However, since the dry and wet garbage collected in the garbage collection box 3 are in a mixed and closed state, the garbage collection box 3 is prone to stink after long-term use, and the user experience is poor; preferably, in the present embodiment, the garbage collection box 3 includes a liquid garbage collection area 32 which is separated and located at the bottom and a solid garbage collection area 33 which is located at the top, wherein the solid garbage collection area 32 is provided with a collection inlet 31 which is arranged corresponding to the roller brush 2, and a filter partition 34 is provided between the solid garbage collection area 32 and the liquid garbage collection area 33; the filter partition 34 is provided with one or more rows of grooves 34a, and a plurality of filter holes 34b which are distributed at intervals are provided in the grooves 34a; in actual use, all garbage first enters the solid garbage collection area 32 through the collection inlet 31, and the liquid garbage will flow into the liquid garbage collection area 33 through the filter holes 34b, which is convenient for the user's needs for classified garbage dumping, and at the same time reduces or avoids the stink problem caused by the dry and wet garbage being mixed together for a long time;

[0053] Preferably, in this embodiment, the solid waste collection area 32 adopts a solid waste collection box body provided with a collection inlet 31, and the liquid waste collection area 33 adopts a liquid waste collection box body, and the solid waste collection box body and the liquid waste collection box body are installed and connected as a whole, wherein the bottom of the solid waste collection box body adopts a filter partition 34, and its cover plate 35 adopts a selectively openable detachable cover plate; in actual application, when dumping garbage, the user can first take out the solid waste collection box body and dump the dry garbage collected by it into a garbage can, and then dump the liquid garbage collected in the liquid waste collection box body into a pool for discharge;

[0054] Since the cleaning device 1 is usually provided with a twisting head 12, the user may lift the cleaning device 1 as a whole during daily use, which will cause the handle 13 and the mounting shell 11 on which the roller brush 2 is mounted to be in a horizontal vertical position, resulting in the collection inlet 31 of the garbage collection box 3 being in a horizontal position. Various types of garbage located in the solid garbage collection box body and the liquid garbage collection box body may leak or overflow, causing pollution to the ground and the cleaning device body; for this reason, preferably, in the present embodiment, the solid garbage collection box body includes a solid garbage collection box side panel 33a located on one side of the collection inlet 31, and the solid garbage collection box side panel 33a is provided with a solid anti-overflow The limiting portion 33b, the solid anti-overflow limiting portion 33b is located below the collection inlet 31; the liquid waste collection box body includes a liquid waste collection box side plate 32a located on one side of the collection inlet 31, the liquid waste collection box side plate 32a is sealed and sleeved on the outside of the solid waste collection box side plate 33a, and the liquid waste collection box side plate 32a is provided with a liquid anti-overflow limiting portion 32b extending obliquely toward the inside of the liquid waste collection box body, and the liquid anti-overflow limiting portion 32b is located below the filter partition 34. The solid anti-overflow limiting portion 33b and the liquid anti-overflow limiting portion 32b can be specifically in the shape of plate ribs, which can effectively prevent the problem of garbage overflowing or overflowing from the collection inlet 31 respectively;

[0055] In order to ensure the installation connection strength between the liquid waste collection box body and the solid waste collection box body and improve the installation convenience, in this embodiment, the end of the liquid waste collection box side plate 32a is provided with an extension boss 32c located outside the collection inlet 31, and the extension boss 32c is connected to the lower end of the collection inlet 31 in a guiding manner;

[0056] Preferably, in this embodiment, a mop installation area is provided at the bottom of the liquid waste collection box body, and a cleaning mop 16 that can contact the ground is arranged in the mop installation area; the mop installation area adopts a limit installation groove 15b structure formed by convex ribs 15a, and the material of the cleaning mop 16 is fluff fiber, and the material of the convex ribs 15a is rubber; during the use of this product, the extremely thin water film remaining on the ground after the rolling brush 2 cleans the ground can be wiped and absorbed by the cleaning mop 16 in the limit installation groove 15b, so that the ground after cleaning can be dried quickly, avoiding the risk of the user falling due to excessive slipping of the ground The rubber convex ribs 15a around the limit installation groove 15b can be used as extrusion ribs during actual maintenance. The Shore A hardness of the material is 50-100 degrees, which is convenient for users to press the liquid garbage collection box up and down on the wall of the pool to squeeze out the water after dumping the wet garbage, so as to keep the cleaning mop dry. From the perspective of preference, the material of the cleaning mop 16 is preferably a flannel material with a water absorption rate of 1.1-1.5, which can ensure the absorption of the residual water film on the ground, and at the same time avoid the cleaning mop 16 absorbing too much water, which is not easy to dry and breed bacteria.

[0057] The present embodiment further proposes a liquid sprayer 6 of a cleaning device 1, which is mounted on a mounting housing 11 of the cleaning device 1.
