Description

Technical Field

[0001] The invention relates to the field of cleaning, and in particular to a shell installation structure of 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. The roller brush is used to roll the garbage on the ground and send the garbage to the garbage collection area to clean the ground. However, when this method is used in actual ground cleaning applications with different cleaning environments, it is found that the cleaning effect obtained by simply relying on the rolling contact between the roller brush and the ground and the centrifugal effect is poor, and the problem of missing garbage on the ground is more prominent.

[0004] To this end, the applicant hopes to make targeted improvements to the above technical problems to make them more suitable for being easily accepted by the general public and bringing a good cleaning experience. Summary of the invention

[0005] The object of the present invention is to provide a shell installation structure of a cleaning device, which can significantly reduce or avoid garbage leakage and effectively improve the cleaning effect of the composite sweeping and mopping function of the present invention.

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

[0007] A housing installation structure for a cleaning device comprises a housing for installing a roller brush.

[0008] One end of the roller brush is relatively rotatably mounted on the mounting housing, and the other end is drivingly connected to a roller brush driver. The roller brush can roll and contact with the ground under the driving action of the roller brush driver.

[0009] A garbage collection area is integrally or separately provided in the installation shell, and the garbage collection area is provided with a collection inlet corresponding to the roller brush, and the garbage brought up by the rolling contact is collected into the garbage collection area under the rotation of the roller brush; wherein,

[0010] The roller brush and the mounting shell cooperate with each other to form a floor scraping guide connected to the collection inlet, which is used to scrape residual garbage off the ground and transfer it to the garbage collection area through the rotational movement of the roller brush; wherein the floor scraping guide includes a floor scraping strip and a guide surface respectively located on the mounting shell, the floor scraping strip is in flexible pressure contact with the ground, and the guide surface is connected to the collection inlet.

[0011] 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.

[0012] 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.

[0013] As a preferred technical solution, the mounting shell is integrally connected to the handle through a twisting head; a liquid storage box is installed on the handle, and the outlet of the liquid storage box is provided with a valve body driven by a mechanical pump or an electric pump, and the mechanical pump or the electric pump is connected to at least one nozzle through a liquid spray pipeline, and the cleaning liquid is sprayed onto the ground and / or the roller brush through the nozzle; the liquid storage box is installed at the front part of the handle so that the center of gravity of the handle is located at the front end to prevent the handle from tipping over.

[0014] As a preferred technical solution, the roller brush includes a driving roller that is driven by a roller brush driver and is relatively rotatably mounted on the mounting shell, the outer periphery of the driving roller is covered with a flexible roller brush for flexible contact with the ground, wherein one end of the driving roller is detachably mounted on the mounting shell, and the other end thereof is detachably driven and connected to the output end of the roller brush driver.

[0015] As a preferred technical solution, the twisting head includes a twisting mounting part and a twisting body installed as an integral whole, the twisting mounting part is snap-fitted with the handle, and the twisting mounting part is relatively rotatably mounted on the inner circumference of the twisting body, and at the same time, the two ends of the twisting body are respectively relatively rotatably mounted on the mounting shell.

[0016] As a preferred technical solution, the mounting shell is provided with a roller brush opening and a centrifugal guide plate for the roller brush to roll in contact with the ground. One side of the roller brush opening is connected to the lower end of the garbage collection area through the ground scraping guide, and the other side is connected to the upper end of the garbage collection area through the centrifugal guide plate. At the same time, the centrifugal guide plate cooperates with the roller brush gap guide.

[0017] As a preferred technical solution, a roller brush scraper which is in flexible pressure contact with the roller brush is provided on the centrifugal guide plate, and 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 scraper is provided with a liquid storage space, and the liquid storage space is connected to the garbage collection area through a drainage path; when the roller brush is rotating, the roller brush scraper and the ground scraping guide are linked to scrape away, so as to form a directional closed-loop cleaning path between the ground, the roller brush and the garbage collection area, so as to reduce or avoid missing garbage.

[0018] As an optimal technical solution, the centrifugal guide plate is installed separately from the mounting shell, and the distance between the centrifugal guide plate 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 centrifugal guide plate 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 centrifugal guide plate and the roller brush is beneficial to the mopping effect on the ground.

[0019] As an optimal technical solution, a receiving guide groove connected to the ground scraping guide is provided at the bottom of the mounting shell for receiving droplets dropped when the roller brush rotates, and transferring the liquid in the receiving guide groove to the garbage collection area through the ground scraping guide.

[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 attracted by the negative pressure and is picked up by the roller brush in a rotating motion state. At the same time, the centrifugal force effect generated when the roller brush rotates transmits the garbage to the garbage collection area corresponding to the roller brush. However, the directional garbage collection function that relies solely on 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 ground scraping guide connected to the collection inlet. The ground scraping guide specifically includes a guiding surface and a ground scraping strip. The ground scraping strip is in flexible pressure contact with the ground to scrape off the residual garbage on the ground and transfer the residual garbage on the ground to the garbage collection area through the cooperation of the guiding surface and the rotating centrifugal force effect of the roller brush. This can significantly reduce or avoid garbage omissions, effectively improve the cleaning effect of the composite sweeping and mopping function of the present invention, make it easy to be widely accepted by the general public, and bring a good cleaning experience.

DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figures 1 to 12 As shown, a housing mounting structure of a cleaning device 1 includes a mounting housing 11 for mounting a roller brush 2, including an upper mounting housing 11a and a lower mounting housing 11b which are mounted and connected as one body; the mounting housing 11 is mounted and connected as one body with a twisting head 12; as a preferred technical solution, in this embodiment, the twisting head 12 includes a twisting mounting portion 12a and a twisting body 12b which are mounted as one body, the twisting mounting portion 12a is engaged with the handle 13, and the twisting mounting portion 12a is relatively rotatably mounted on the inner circumference of the twisting body 12b, and both ends of the twisting body 12b are relatively rotatably mounted on the mounting housing 11;

[0036] One end of the roller brush 2 is relatively rotatably mounted on the mounting shell 11, and the other end thereof is drivingly connected to the roller brush driver 7. The roller brush driver 7 is mounted in the mounting shell 11. The roller brush 2 can roll and contact with the ground under the driving action of the roller brush driver 7. The lower mounting shell 11b realizes displacement movement on the ground through the main roller assembly 14a and the auxiliary roller assembly 14b, thereby avoiding or reducing the frictional contact between the roller brush 2 and the ground. As a preferred technical solution, in this embodiment, the roller brush driver 7 is composed of a motor 71 and a pulley 72, and the motor 71 is charged by a battery 73. The roller brush 2 includes a driving roller 2a driven by the roller brush driver 7 and relatively rotatably mounted on the mounting shell 11. The outer periphery of the driving roller 2a is coated with a flexible roller brush 2b for flexible contact with the ground, wherein one end of the driving roller 2a is detachably mounted on the mounting shell 11, and the other end thereof is detachably drivingly connected to the output end of the pulley 72. The specific detachable structure can be selected according to conventional technical means of those skilled in the art, and is not particularly limited in this embodiment.

[0037] As a preferred technical solution, in this embodiment, 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;

[0038] 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;

[0039] A garbage collection area is integrally or separately provided in the installation shell 11. The garbage collection area specifically adopts a garbage collection box 3 that is detachable relative to the installation shell 11. The garbage collection box 3 is provided with a collection inlet 31 corresponding to the roller brush 2. The garbage brought up by rolling contact is collected into the garbage collection box 3 under the rotation of the roller brush 2; wherein,

[0040] 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 rotation 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, the guide surface 52 is connected to the collection inlet 31, and the floor scraping strip 51 extends obliquely along the direction of the roller brush 2; in specific implementation, the floor scraping strip 51 can be a rubber scraping strip, and its front end is designed to be a sharp wedge shape extending obliquely along the direction of the roller brush, and the floor scraping strip 51 is provided with a plurality of guide surfaces 52 ... The Shore A hardness of 1 is 40-80 degrees, and the more preferred range is 45-70 degrees, which can ensure that when the front end of the floor scraper 51 contacts the ground, its wedge-shaped part is appropriately deformed, so that its flexible contact with the ground is closer. After the roller brush 2 sweeps the garbage on the ground, the sewage water film left on the ground can be pushed forward into a ball, and the guide surface 52 cooperates with the rotating centrifugal force effect of the roller brush 2 to transfer it to the garbage collection box 3, without causing residual water on the ground after cleaning, significantly improving the sewage collection rate, and thus achieving the scraping and guiding collection of residual or missed garbage on the ground;

[0041] 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 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 results in a poor scraping effect of the floor scraper and a thick residual water film. As a preferred technical solution, in this embodiment, the floor scraper 51 is provided with a swing installation hook groove 51a, which can be used to swing the installation hook groove 51a. The floor scraper 51 is relatively swingably mounted on the guide surface 52, and 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 residual liquid or water on the ground, has a good scraping effect, and is easy and convenient for users to clean;

[0042] In this 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 of the roller brush 2, 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, this embodiment further proposes that the floor scraper The two ends of the scraper 51 are provided with protrusions 54, respectively, forming a concave reflux collection area 55 located in the middle, and the garbage in the concave reflux collection area 55 is transferred to the garbage collection box 3 through the rotation of the roller brush 2; 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 respectively arranged at the two ends of the guide surface 52 and the floor scraper 51, a concave reflux collection area 55 with high sides and low middle is formed. When working, the sewage at the two ends of the water collecting 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;

[0043] As a preferred technical solution, a liquid storage box 61 is installed on the handle 13, and the outlet of the liquid storage box 61 is provided with a valve body 62 driven and connected to an electric pump 64 (in other embodiments, a mechanical pump may also be used), and the electric pump 64 is connected to at least one nozzle through a liquid spraying pipeline 63, and the cleaning liquid (usually water) is sprayed onto the ground and / or the roller brush 2 through the nozzle; specifically preferably, in this embodiment, the liquid storage box 61 is installed on the handle 13, specifically, on the front part of the handle 13, and the nozzle 65 is installed on the centrifugal guide plate 4, and the centrifugal guide plate 4 is provided with a nozzle 66 for inserting the nozzle 65; the liquid spraying pipeline 63 After penetrating the twisting head 12, the nozzle 65 is connected, and the cleaning liquid is sprayed onto the ground through the nozzle 65; the liquid spraying pipeline 63 in this embodiment is led from the upper handle 13 to the front end of the lower mounting shell 11, rather than being directly arranged on the lower mounting shell 11, so that the user can easily disassemble and assemble the liquid storage box 61, and the wiring installation of the liquid spraying pipeline 63 is a closed structure, which will not be exposed to the outside and easily hit, and is also beneficial to the overall aesthetics of the cleaning device 1; the liquid storage box 61 is arranged in front of the handle 13 to promote the center of gravity of the handle 13 to move forward, maintain its standing state, and avoid the risk of the handle-type cleaning device 1 being easy to fall over;

[0044] As a preferred technical solution, the mounting shell 11 is provided with a roller brush opening 11c and a centrifugal guide plate 4 for the roller brush 2 to roll in contact with the ground. One side of the roller brush opening 11c is connected to the lower end of the garbage collection box 3 through the ground scraping guide 5, and the other side is connected to the upper end of the garbage collection box 3 through the centrifugal guide plate 4. At the same time, the centrifugal guide plate 4 and the roller brush 2 are gap-guided. The purpose of setting the gap-guided cooperation is mainly to avoid as much as possible that the garbage is formed in the process of rotation of the roller brush 2. The centrifugal force tangent outlet deviates from the collection inlet and causes the garbage to splash around. Specifically, it is recommended that the gap between the centrifugal guide plate 4 and the roller brush 2 should not exceed 30mm, preferably, not exceed 15-20mm;

[0045] As a preferred technical solution, a roller brush scraper 41 is provided on the centrifugal guide plate 4, which 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 and transfer it to the garbage collection box 3; wherein the roller brush scraper 41 is provided with a liquid storage space, and the liquid storage space is connected to the garbage collection box 3 through a drainage path; when the roller brush is rotating, the roller brush scraper 41 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 reduce or avoid garbage leakage;

[0046] Specifically, 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.

[0047] 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.

[0048] 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 (not shown) 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;

[0049] Considering that in the cleaning condition, when the interference between the roller brush scraper 41 and the cleaning fibers on the roller brush 2 in this embodiment is too large, the cleaning fibers on the roller brush 2 become flaky after being wetted, resulting in a small dust holding capacity of the cleaning fiber fluff, which is not conducive to the cleaning effect of garbage on the ground. Moreover, when the cleaning condition is completed and the mopping condition is performed, the interference between the roller brush scraper 41 and the cleaning fibers on the roller brush 2 in this embodiment 1 can be increased, and the water on the cleaning fibers can be scraped out to a greater extent by the roller brush scraper 41. The residual water film on the ground is basically cleaned up over and over again, which solves the problem that the ground does not dry up for a long time after cleaning, and at the same time improves the roller brush 2, so as to improve the dryness of the cleaning fibers on the roller 2, and avoid secondary contamination of the cleaned floor caused by bacterial growth; therefore, as a preferred technical solution, the centrifugal guide plate 4 is installed and connected with the mounting shell 11 separately, and the distance between the centrifugal guide plate 4 and the roller brush 11 can be adjusted by lifting and lowering movement, so as to achieve the adjustment of the flexible pressure contact effect between the roller brush scraper 41 and the roller brush 2, and meet the cleaning requirements of different cleaning conditions; wherein, in the cleaning condition, increasing the distance between the centrifugal guide plate 4 and the roller brush 2 is beneficial to the cleaning effect of the roller brush 2 on the floor, and in the mopping condition, reducing the distance between the centrifugal guide plate 4 and the roller brush 2 is beneficial to the mopping effect on the floor.

[0050] This embodiment also proposes the following specific structure to adjust the distance between the centrifugal guide plate 4 and the roller brush 2:

[0051] Specifically, in this embodiment, a guide plate driver 8 is installed between the centrifugal guide plate 4 and the mounting housing 11, and the centrifugal guide plate 4 can be lifted relative to the mounting housing 11 through the guide plate driver 8, and the distance between the centrifugal guide plate 4 and the roller brush 2 is adjusted by the lifting movement;

[0052] In this embodiment, the guide plate driver 8 adopts a mechanical driver; the mechanical driver includes a limiting boss 81 fixedly mounted on the lower end of the centrifugal guide plate 4, and a limiting slide groove 82 is provided on the mounting shell 11, which is selectively limited and plugged with the limiting boss 81; the limiting boss 81 is provided with a limiting tooth 81a, and a limiting groove 82a is provided at the bottom of the limiting slide groove 82, and a spring 83 is provided between the limiting tooth 81a and the limiting groove 82a; in actual use, when the centrifugal guide plate 4 is pressed downward, the spring 83 is compressed by force, driving the limiting tooth 81a to move downward until the limiting boss 81 of the centrifugal guide plate 4 is limitedly plugged with the limiting slide groove 82, and the limiting tooth 81a is engaged with the limiting groove 82a, at the same time, the spacing between the roller brush scraper 41 and the roller brush 2 is reduced, and it is in the mopping working condition at this time; press the centrifugal guide plate 4 downward again, and the spring 83 is compressed by force, driving the limiting tooth 81a to move downward, until the limiting boss 81 of the centrifugal guide plate 4 is limited and plugged with the limiting slide groove 82, and the limiting tooth 81a is engaged with the limiting groove 82a, at this time, the spacing between the roller brush scraper 41 and the roller brush 2 is reduced, and it is in the mopping working condition at this time; The center guide plate 4, at this time, the limiting boss 81 and the limiting slot 82 are no longer limited and plugged, the spring 83 is reset, and at the same time the limiting tooth 81a and the limiting groove 82a are out of the clamping state, and the distance between the roller brush scraper 41 and the roller brush 2 increases, and it is in a cleaning condition; the spacing adjustment range achieved by the above mechanical drive can be 1-3mm, which can be specifically selected according to actual cleaning needs, and this embodiment does not specifically limit it; in other embodiments, the guide plate driver 8 can also adopt an electric driver or an electromagnetic coil driver, as long as the spacing adjustment between the roller brush scraper 41 and the roller brush 2 is achieved, those skilled in the art can make conventional technical replacement schemes for the guide plate driver 8 based on the technical ideas of this invention, and these replacement schemes all belong to the protection concept scope of the present invention.

[0053] During actual in-depth application, the applicant found that when the cleaning device 1 is used to clean a wet floor with liquid garbage, even if the roller brush 2 squeezes out water through flexible pressure contact with the roller brush scraper 41, sewage will inevitably flow downward and drip, causing sewage leakage; for this reason, preferably, in the present embodiment, a receiving guide groove 15 connected to the guide surface 52 is provided at the bottom of the lower mounting shell 11b, and the receiving guide groove 15 is located below the roller brush 2 and is 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.

[0054] The present embodiment firstly utilizes the rolling contact between the roller brush 2 and the ground, so that the garbage on the ground is attracted by the negative pressure and is lifted up by the roller brush 2 in a rotating motion state. At the same time, the centrifugal force effect generated when the roller brush 2 rotates transmits the garbage to the garbage collection box 3 corresponding to the roller brush 2. However, the directional garbage collection function that relies solely on the centrifugal force effect is poor, which will lead to more garbage omission. For this reason, the present embodiment also creatively proposes to set a ground scraping guide 5 connected to the collection inlet 31. The ground scraping guide 5 specifically includes a guiding surface 52 and a ground scraping strip 51. The ground scraping strip 51 is in flexible pressure contact with the ground to scrape the residual garbage on the ground and transfer the residual garbage on the ground to the garbage collection box 3 through the guiding surface 52 and the rotating centrifugal force effect of the roller brush 2.
