Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a base station and a cleaning robot system. BACKGROUND

[0002] With the development of technology, the function of household sweeping robots is increasingly powerful, and a cleaning robot system is born. The cleaning robot system generally includes a sweeping robot and a base station. The base station provides charging, cleaning mop and other functions for the sweeping robot. Due to the cooperation of the base station, the degree of automation of the sweeping robot is higher.

[0003] For the sweeping robot with a rotating mop, the base station needs to clean the rotating mop. At present, the general cleaning method mainly sets a cleaning groove (a cleaning recess structure lower than the periphery) in the base station. The sweeping robot is parked in the base station, and then the mop is rotated and cleaned in the cleaning groove. According to the general principle of cleaning, an upward protrusion is often provided in the cleaning groove. In this way, the mop is scraped by the protrusion, which is similar to the cleaning principle of a washboard. In addition, in order to improve the cleaning effect and efficiency, some technical solutions also configure a water supply structure for washing the mop upward in the cleaning groove or set a radial groove through which water is supplied (the mop passes through the radial groove when rotating, so that the mop is wet and cleaned). In this way, it is beneficial to improve the cleaning effect and efficiency, but it also produces sewage, which is deposited in the cleaning groove or is pumped away through a sewage discharge structure. In addition, in order to distinguish the cleaning area and the sewage area, a filter screen structure is also provided (for example, the filter screen 212 disclosed in CN103006153A intelligent floor cleaner divides the cleaning unit 22 into two layers, the upper side of the filter screen is the cleaning area, and the lower side is the sewage area. The sewage area is provided with a sewage inlet 29 to pump away the sewage).

[0004] As can be seen from the above, there are mainly three structures for the base station to use water (i.e. cleaning liquid). The first one is to wash the mop upward. Since water is sprayed, it needs to be pressurized and sprayed, so the structure is relatively complex, the energy consumption is relatively high, and the water consumption is relatively large. The second one is to wet the mop by the radial groove through which water flows. Since water needs to be kept flowing during cleaning, the water consumption is relatively large. The third one is to immerse and wash the mop in the water-filled cleaning unit 22 provided in CN103006153A intelligent floor cleaner. Since a large amount of water needs to be filled in the cleaning unit 22, it cannot be done every time with new water for cleaning, and the water consumption is relatively large. The present applicant will provide another scheme different from the above three schemes. This scheme can achieve immersion and washing, has a certain immersion effect, and is beneficial to use new water for cleaning every time. In addition, since it does not need to continuously supply water as in the first and second schemes, the water consumption is relatively small. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the defects of the prior art, and to provide a base station which can achieve soaking and has a certain soaking effect, and which is conducive to achieving cleaning with new water each time, and which also uses less water during cleaning; and to provide a cleaning robot system which adopts the aforementioned base station and is conducive to cleaning and water saving.

[0006] Compared with the prior art, the present application provides a base station which includes a cleaning part for cleaning a rotating mop, the cleaning part is provided with a water storage area at a position corresponding to a rotating surface of the rotating mop, the water storage area is located on the lower side of the rotating mop, and the water storage area divides the rotating surface into two areas, i.e., a first area in the water storage area and a second area outside the water storage area; the water storage area includes a first part and a second part which are sequentially arranged in the rotating direction of the rotating mop, the rotating mop passes through the first part to enter the water storage area when rotating, and the rotating mop passes through the second part to exit the water storage area when rotating; the base station also includes an inlet and outlet structure for supplying clean cleaning liquid to the water storage area and discharging the cleaning liquid after cleaning; the cleaning liquid in the water storage area is used to immerse the lower surface of the part of the rotating mop that enters the water storage area, and the second part is used to scrape the lower surface when the rotating mop rotates and to block the lower surface from carrying the cleaning liquid out of the water storage area.

[0007] In some embodiments, the water storage area is arranged to be inclined relative to the horizontal plane, and the inclined arrangement mainly collects the cleaning liquid in the water storage area on one circumferential side of the rotating surface away from the rotating shaft of the rotating mop. After such design, since the purpose of the present disclosure is to achieve a certain soaking effect, a certain water depth is more advantageous to the present disclosure, and in order to obtain a certain water depth, the conventional idea is to increase the water quantity (i.e., to increase the amount of cleaning liquid), and the present disclosure adopts an inclined arrangement, so that the circumferential side of the water storage area has a greater water depth while reducing the amount of cleaning liquid, thereby solving the contradiction between water quantity and water depth with a very simple structure.

[0008] In some embodiments, the base station further includes a support for arranging the rotating mop of the sweeping robot resting thereon to be inclined relative to the horizontal plane, and the water storage area is arranged to be substantially parallel to the rotating mop. After such design, on the one hand, the relative motion interference problem between the rotating mop and the water storage area is reduced, and on the other hand, the outer periphery of the rotating mop and the part of the lower surface of the rotating mop close to the outer periphery can be immersed in the water storage area to a great extent when entering the water storage area, thereby being conducive to better cleaning of the outer periphery and the part of the lower surface close to the outer periphery, which plays an important role in edge cleaning of the sweeping robot, and timely cleaning of the outer periphery is of great significance.

[0009] In some embodiments, the first portion simultaneously serves as a scraping rib for scraping the rotating mop, and the scraping rib is referred to as a first scraping rib. With this design, the scraping rib is increased, which is conducive to better scraping efficiency of the rotating mop, and the structure is simple.

[0010] In some embodiments, the second portion simultaneously serves as a scraping rib for scraping the rotating mop, and the scraping rib is referred to as a second scraping rib. With this design, the scraping rib is increased, which is conducive to better scraping efficiency of the rotating mop, and the structure is simple.

[0011] In some embodiments, a filter screen is arranged between the water storage area and the cleaning part, and the cleaning liquid of the water storage area is discharged to the sewage area of the cleaning part through the filter screen. With this design, the filter screen can filter large dirt, so as to avoid deposition in the sewage area and cannot be cleaned, and in addition, the sewage area is separated by the filter screen, which is conducive to the scraping work during scraping, that is, the sewage in the sewage area cannot easily pollute the rotating mop again during scraping.

[0012] In some embodiments, the filter screen is arranged together with the water storage area as a detachable assembly, and the detachable assembly is arranged separately from the cleaning part. With this design, the filter screen is arranged together with the water storage area as a detachable assembly, which not only provides better support for the water storage area, but also facilitates cleaning, and when the filter screen is removed, the sewage area is also exposed, which is easier to clean.

[0013] In some embodiments, the cleaning part is provided with a cleaning disc, and the cleaning disc includes circumferential enclosures, and the circumferential enclosures form the water storage area; the circumferential enclosures are provided with a first portion and a second portion. With this design, the water storage area is provided by the cleaning disc, which is conducive to simplifying the structure of the cleaning part itself.

[0014] In some embodiments, the cleaning disc is arranged to be reversely rotatable relative to the cleaning part, and the reverse rotation arrangement enables the cleaning disc to switch between the water storage position and the drainage position. With this design, since the water storage position and the drainage position are distinguished, it is not necessary to simultaneously realize water storage and drainage in a fixed position, which provides a structural basis for further optimizing water storage and drainage.

[0015] In some embodiments, the circumferential direction of the cleaning disc is respectively provided with a water inlet and a water outlet. In the water storage position, the water inlet is connected with the water supply port for liquid inlet, and the water outlet is closed. In the water discharge position, the water inlet is misaligned with the water supply port, and the water outlet is open, and the cleaning liquid in the water storage area of the cleaning disc is discharged into the cleaning part through the water outlet. In this way, the water inlet and outlet structure is simple, and in addition, by combining the aforementioned cleaning disc, the cleaning part can be arranged in a forward and reverse rotation manner. The water outlet is in completely different positions in the water storage position and in the water discharge position. At the same time, due to the water outlet being arranged in the circumferential direction of the cleaning disc, it is close to the water storage area. Therefore, the above two technical improvements are more conducive to unobstructed discharge. In addition, by arranging the water inlet and outlet in the circumferential direction of the cleaning disc, and realizing the connection and misalignment of the water inlet and the water supply port, and the closing and non-closing of the water outlet by rotating, the inlet and outlet structure is simplified, for example, the water supply port does not need to rotate with the cleaning disc.

[0016] In some embodiments, the cleaning disc is substantially formed by three parts, i.e., a circumferential part, a left side part and a right side part, and is arranged in an inclined manner. The cleaning disc has a rotation center, the top of the rotation center is provided with a water inlet, and the left side part or the right side part is provided with a water outlet. In the water storage position, the water inlet and the water supply port are sequentially arranged from low to high in the inclined direction and are connected. In the water discharge position, the water outlet is at the low part of the cleaning disc and is open. In this way, on the one hand, it is more conducive to water inlet, thereby making water storage more efficient. In addition, by using inclination, the cleaning liquid can enter the water storage area relatively quickly through natural flow without the need for pump pressure delivery. On the other hand, water discharge is more efficient.

[0017] In some embodiments, the top has a matching section for cooperating with the water supply port to guide the rotation of the cleaning disc during the rotation of the cleaning disc switching. In this way, the reliability and stability of the rotation of the cleaning disc are improved, and the structure is simple.

[0018] In some embodiments, the water outlet is located in the side part opposite to the rotation direction of the cleaning disc when the cleaning disc switches to the water discharge position. In this way, in the water discharge position, the water outlet is at the lowest part of the cleaning disc, and in addition, by using the inertia of the cleaning liquid itself, when the cleaning disc rotates, the cleaning liquid is thrown out of the water storage area through the water outlet, thereby further improving the water discharge efficiency.

[0019] In some embodiments, a first rotation limiting member and a second rotation limiting member are arranged in the radial direction of the rotation surface. The first rotation limiting member limits the rotation of the cleaning disc in the water storage position, and the second rotation limiting member limits the rotation of the cleaning disc in the water discharge position. The first rotation limiting member and the second rotation limiting member constitute the forward and reverse rotation range of the cleaning disc. In this way, the structure is simple and the limiting is reliable.

[0020] In some embodiments, the circumferential direction of the cleaning disc is provided with a drainage port, and the first rotation limiting piece also serves as a closing piece for closing the drainage port when the water storage position is reached. After such design, the function of sealing the drainage port is realized while limiting, the structure is simple and compact, and the performance is stable and reliable.

[0021] In some embodiments, the first rotation limiting piece and / or the second rotation limiting piece are also used for scraping connection with the lower surface of the rotating mop. After such design, during cleaning, scraping is used to improve the cleaning efficiency, and during drying, scraping is used to improve the drying efficiency.

[0022] In some embodiments, the area between the first rotation limiting piece and the second rotation limiting piece and having the cleaning disc is referred to as a cleaning area, and the area between the first rotation limiting piece and the second rotation limiting piece and not having the cleaning disc is referred to as a drying area. When the water storage position is reached, the cleaning liquid in the water storage area of the cleaning disc is mainly discharged into the cleaning part through the cleaning area. After such design, on the one hand, the partition is optimized, and on the other hand, the cleaning liquid is mainly discharged through the cleaning area, so the drying area is not easy to get dirty, reducing the user's cleaning burden.

[0023] In some embodiments, a filter screen is further included, the cleaning disc, the filter screen, and the cleaning part are sequentially arranged from top to bottom, the cleaning liquid in the water storage area of the cleaning disc is discharged into the sewage area of the cleaning part located on the lower side of the filter screen through the filter screen, and the cleaning area and the drying area both have filter holes of the filter screen. After such design, on the one hand, when the cleaning liquid is mainly discharged through the cleaning area, a good filtering effect can be achieved to avoid large dirt or hair falling into the sewage area, and on the other hand, the filter holes of the drying area can directly fall into the sewage area through the filter holes when the water scraped by the rotating mop is relatively wet, which is convenient and efficient.

[0024] In some embodiments, the drying area is provided with a drying device air outlet on one side. After such design, on the one hand, it is conducive to improving the drying efficiency, and on the other hand, in combination with the blocking effect of the first rotation limiting piece and the second rotation limiting piece, the drying area has a blocking and gathering effect on the airflow (cold airflow or hot airflow) blown from the outside, thereby further improving the drying efficiency.

[0025] In some embodiments, the rotating mop serves as a power source for the forward and reverse rotation of the cleaning disc, and the cleaning disc is driven to forward and reverse rotation by the forward and reverse rotation of the rotating mop. After such design, the power source problem of the forward and reverse rotation of the cleaning disc relative to the cleaning part is greatly simplified, that is, there is no need to separately provide a power source for driving the forward and reverse rotation of the cleaning disc relative to the cleaning part in the base, which not only has a simple structure, but also is reliable and stable.

[0026] In some embodiments, the cleaning disc is connected with a rotation guide structure, and the forward and reverse rotation of the rotating mop drives the cleaning disc to rotate forward and reversely along the rotation guide structure through the rotating mop scraping the first part and / or the second part with the lower surface thereof. In this way, the forward and reverse rotation of the cleaning disc is driven by the rotating mop scraping the first part and / or the second part with the lower surface thereof, which greatly simplifies the transmission structure for driving the forward and reverse rotation, and the scraping can be used for cleaning and wiping dry, and one structure has multiple functions.

[0027] In some embodiments, the rotation guide structure comprises a rotating shaft and / or an arc-shaped guide rail. In this way, the structure is simple.

[0028] In some embodiments, the water storage position also serves as a cleaning position, and the water drainage position also serves as a wiping dry position; in the cleaning position, the water storage area has cleaning liquid, the lower surface of the part of the rotating mop entering the water storage area is wetted and cleaned by the cleaning liquid, and when the rotating mop rotates, the part of the rotating mop outside the water storage area enters the water storage area, and the part of the rotating mop inside the water storage area exits the water storage area after being scraped by the second part; in the wiping dry position, the water storage area is drained of the cleaning liquid, and when the rotating mop rotates, the part of the rotating mop outside the water storage area enters the water storage area after being scraped by the second part, and the part of the rotating mop inside the water storage area exits the water storage area after being scraped by the first part or after being scraped by the first part. In this way, one position has multiple functions, which is conducive to simple structure, and on the other hand, the water storage position directly stores water for cleaning, and the water drainage position directly drains water for wiping dry, which is conducive to improving efficiency.

[0029] In some embodiments, a filter screen is further included, the cleaning disc, the filter screen and the cleaning part are sequentially arranged from top to bottom, and the cleaning disc is rotatably connected with the filter screen, and the cleaning liquid in the water storage area of the cleaning disc is discharged to the sewage area of the cleaning part located below the filter screen through the filter screen. In this way, the filter screen can play a certain filtering role to prevent large dirt or hair from falling into the sewage area, and on the other hand, the sewage area is separated by the filter screen, which is conducive to wiping dry work, i.e., the sewage in the sewage area will not easily pollute the rotating mop again during wiping dry.

[0030] In some embodiments, the filter screen is a detachable assembly together with the cleaning disc, and the detachable assembly is separably arranged with the cleaning part. In this way, the filter screen and the cleaning disc are convenient to clean, and the sewage area is also convenient to clean.

[0031] After adopting the above structure, compared with the prior art, the present application has the following advantages:

[0032] Since the position of the cleaning part corresponding to the rotating surface of the rotating mop is provided with the water storage area, the water storage area is located at the lower side of the rotating mop, the water storage area divides the rotating surface into two areas, the first area in the water storage area and the second area outside the water storage area, so the water storage area only occupies a section, when water is supplied to the water storage area, a large amount of water is not required, only the degree that the cleaning liquid in the water storage area can immerse the lower surface of the part of the rotating mop entering the water storage area is required, so the water consumption is less while achieving the immersion cleaning, and the rotating mop passes through the first part into the water storage area when rotating, the rotating mop passes through the second part out of the water storage area when rotating, the second part is used to scrape the lower surface when the rotating mop rotates and block the lower surface from taking the cleaning liquid out of the water storage area, so the lower surface of the rotating mop is cleaned to the part entering the water storage area, and when entering and leaving, the second part also tries to keep the cleaning liquid in the water storage area from being taken out, so that the depth of the water storage area can be maintained with less cleaning liquid. During the rotation of the rotating mop, the part of the lower surface of the rotating mop entering the water storage area will be immersed in the cleaning liquid for a period of time, and the rotation of the rotating mop will also stir the cleaning liquid, thereby enhancing the cleaning of the part, and in addition, the part will also be scraped by the second part to leave the cleaning liquid every time it leaves the water storage area, so the cleaning effect is good, but the water consumption is less.

[0033] In addition, since the required cleaning liquid is less, the cleaning liquid can be replaced every time without worrying about consuming too much cleaning liquid, so it is beneficial to achieve cleaning with new water every time, or replace the cleaning liquid 2 or 3 times, at this time, the depth of the water storage area is set to be relatively deeper than the structure that replaces the cleaning liquid every time, so if more times of use are required before replacing the cleaning liquid, the depth of the water storage area can be increased to solve the problem.

[0034] The application also provides a cleaning robot system, comprising a sweeping robot and a base station, the sweeping robot is provided with a rotating mop, and the base station adopts the above base station.

[0035] The beneficial effects of the above technical scheme are that it is beneficial to cleaning and water saving, and specifically, while saving water, not only has a good cleaning effect and efficiency on the rotating mop, but also improves the cleaning effect and efficiency of the sweeping robot, when the rotating mop is relatively clean, the sweeping robot using the rotating mop can better clean the cleaned surface, when the rotating mop ensures the cleanliness to meet the requirements while reducing the time for cleaning the rotating mop, the time spent by the sweeping robot staying at the base station for cleaning is less, so it is beneficial for the sweeping robot to obtain more time to clean the cleaned surface, thereby improving the overall cleaning efficiency.

[0060] In some embodiments, reference is made to Figure 1 A base station is shown, the rotating surface 3 is a virtual surface formed by the rotation of the rotating mop 1, therefore represented by a dotted line, in Figure 1 , the cleaning part 2 is provided with a water storage area 4, the water storage area 4 is located at the lower side of the rotating mop 1, the specific shape of the water storage area 4 can be various, therefore cannot be exhausted, and based on Figure 1 shown, the shape of the water storage area 4 is a fan ring.

[0061] In some embodiments, reference is made to Figure 2 A base station is shown, similarly, the rotating surface 3 is a virtual surface formed by the rotation of the rotating mop 1, therefore represented by a dotted line, in Figure 2 , the cleaning part 2 is provided with a cleaning disc, the cleaning disc is provided with a water storage area 4, the cleaning disc is located at the lower side of the rotating mop 1, the specific shape of the cleaning disc can be various, therefore cannot be exhausted, and based on Figure 2 shown, the shape of the cleaning disc is a fan ring.

[0062] In some embodiments, reference is made to Figure 2 A base station is shown, in Figure 2 , the cleaning disc can be provided with forward and reverse rotation relative to the cleaning part 2, the cleaning disc is provided with a water storage area 4, the cleaning disc is located at the lower side of the rotating mop 1.

[0063] In some embodiments, reference is made to Figure 2 A base station is shown, in Figure 2In this configuration, the cleaning disc can be rotated forward and backward relative to the cleaning section 2, and the cleaning disc is connected to a rotating guide structure. The forward and reverse rotation of the rotating mop 1 is achieved by the lower surface of the rotating mop 1 scraping against the first part 5 and / or the second part 6, which drives the cleaning disc to rotate forward and backward via the rotating guide structure. Various rotating guide structures are possible; any structure suitable for guiding the cleaning disc to rotate forward and backward relative to the cleaning section 2 is acceptable, therefore, it is impossible to exhaustively list them all. Based on... Figure 2 As shown, the rotation guide structure is an arc-shaped guide rail 23, and based on Figure 16 , 17 As shown, the rotational guide structure uses a rotating shaft 22 for rotational guidance.

[0064] In some embodiments, reference Figure 3 The image shows a base station. Similarly, rotating surface 3 is a virtual surface, formed by rotating the rotating drag 1, and is therefore represented by a dashed line. Figure 3 In the cleaning unit 2, multiple water storage areas 4 are provided in the area corresponding to one rotating mop 1. These water storage areas 4 are located on the underside of the rotating mop 1. The specific shapes of the water storage areas 4 can vary greatly and cannot be exhaustively listed. Based on... Figure 3 As shown, the water storage area 4 is shaped like a fan ring.

[0065] In some embodiments, reference Figure 4 The image shows a base station. Similarly, rotating surface 3 is a virtual surface, formed by rotating the rotating drag 1, and is therefore represented by a dashed line. Figure 4 In the middle, the cleaning part 2 is provided with a water storage area 4, which is located on the lower side of the rotating mop 1, and the water storage area 4 is provided with a water supply hole 24 and a water outlet hole 25.

[0066] In some embodiments, reference Figure 4 , Figure 8 As shown, in Figure 8 In the middle, the water storage area 4 is set at an angle, and the water supply hole 24 and the water outlet hole 25 are set at different heights along the angle. In this way, the water in the water supply hole 24 naturally flows to the side of the water outlet hole 25 and mainly accumulates on the side of the circumferential part 14. When draining, the water outlet hole 25 is opened, and due to the height difference, the drainage can be faster and cleaner.

[0067] In some embodiments, reference Figure 4 The image shows a base station, based on Figure 4 As shown, the water storage area 4 is fan-shaped, and based on Figure 5 , 6 As shown in Figures 7 and 8, the shape of the water storage area 4 is also different.

[0068] In some embodiments, reference Figure 4 , 5The cleaning part 2 further comprises a first protrusion 29 and a second protrusion 30, and a drying area is formed between the first protrusion 29 and the second protrusion 30 and faces the drying device air outlet 21.

[0069] In some embodiments, referring to Figure 4 , 5 The cleaning part 2 is provided with two corresponding areas corresponding to the two rotating mops 1, and a distributor 42 is arranged between the two corresponding areas. The distributor 42 is arranged in communication with the total air outlet 41 of the drying device, and the distributor 42 has two drying device air outlets 21, which face the respective drying areas.

[0070] In some embodiments, referring to Figure 11 , 12 The cleaning part 2 is provided with a cleaning disc, and the cleaning disc is arranged in the water storage area 4 and is located on the lower side of the rotating mop 1. The specific shape of the cleaning disc can be various, and thus cannot be enumerated. Referring to Figure 11 , 12 The shape of the cleaning disc is a fan shape, and the cleaning disc can be arranged to be reversely rotatable relative to the cleaning part 2. The cleaning disc further comprises a first rotation limiting member 18 and a second rotation limiting member 19 arranged along the radial direction of the rotating surface 3. The first rotation limiting member 18 constitutes rotation limiting of the cleaning disc when in the water storage position, and the second rotation limiting member 19 constitutes rotation limiting of the cleaning disc when in the water drainage position. The first rotation limiting member 18 and the second rotation limiting member 19 constitute the forward and reverse rotation range of the cleaning disc. The first rotation limiting member 18 simultaneously serves as the first protrusion 29, and the second rotation limiting member 19 simultaneously serves as the second protrusion 30.

[0071] In some embodiments, referring to Figures 1 to 7 The cleaning disc is substantially surrounded by three parts, which are a circumferential part 14, a left side part 15, and a right side part 16.
