Description

Technical Field

[0001] The present invention relates to the technical field of cleaning robots, and in particular to a base station and a cleaning robot. Background Art

[0002] With the continuous development of the cleaning robot technology field, cleaning robots have entered many ordinary households to clean the floor, effectively reducing people's housework burden. For some cleaning robots with mopping parts to achieve the mopping function, in order to reduce the trouble of users frequently changing and washing the mopping parts, the mopping parts need to be cleaned through a base station.

[0003] When the mop is cleaning the floor, it is very easy for cotton wool or solid particles on the floor to adhere to the mop. When the existing base station cleans the rotating or rotating mop, it is difficult for the cleaning function of the base station to collect the dirt (such as cotton wool or solid particles) adhered to the mop, and the dirt can only be filtered during the drainage process, so that the dirt accumulates in the mop and the cleaning chamber, which makes it very easy for the mop to adhere to the floor again when mopping the floor, seriously affecting the cleaning effect of the mop by the base station. Summary of the invention

[0004] In view of the above technical problems, it is necessary to provide a base station that can effectively remove cotton wool and solid particle garbage adhering to the mop and rubbish, and filter and collect them to improve the cleaning effect of the base station on the mop and rubbish, and also provide a cleaning robot including the base station.

[0005] The present invention first provides a base station, comprising:

[0006] The seat body has a cleaning chamber for cleaning the mopping member, and the cleaning member and the filter assembly are sequentially arranged in the cleaning chamber along the direction in which the mopping member rotates and cleans in the cleaning chamber; wherein:

[0007] The filter assembly includes a shell having an inner cavity, the shell is provided with at least one dirt collecting hole connected to the inner cavity, and the dirt collecting hole is configured so that dirt scraped off the wiping member by the cleaning member can pass through the dirt collecting hole into the inner cavity of the shell and be collected.

[0008] In this way, the cleaning member and the filter assembly are arranged in sequence along the direction of the mopping and wiping member rotating and cleaning in the cleaning chamber. In this way, when the mopping and wiping member scrapes and cleans with the cleaning member in the cleaning chamber, the dirt scraped off the mopping and wiping member by the cleaning member or the dirt thrown out due to gravity can be thrown in the direction of the filter assembly under the action of centrifugal force, and then enter the inner cavity of the shell through the dirt collecting hole to be intercepted and collected. In this way, the dirt is collected by the filter assembly as the mopping and wiping member scrapes and cleans with the cleaning member, and is directly intercepted in the inner cavity of the shell, so there is no need to wait until the drainage link to filter and collect the dirt, which not only effectively prevents the dirt from being scattered in the cleaning chamber and causing the mopping and wiping member to adhere to the dirt again, thereby causing the base station to have a poor cleaning effect on the mopping and wiping member, but also improves the cleaning efficiency of the base station for the mopping and wiping member.

[0009] In one embodiment of the present invention, the sewage collecting hole is provided in a plurality, and the plurality of sewage collecting holes are evenly opened in the shell.

[0010] With such an arrangement, by increasing the number of the dirt collecting holes, the multiple dirt collecting holes can allow dirt to enter the inner cavity of the shell, thereby improving the efficiency of the filter assembly in collecting dirt.

[0011] In one embodiment of the present invention, the filter assembly further comprises an expansion bottom shell fixed relative to the shell and having an internal space, wherein the internal space is communicated with the inner cavity of the shell;

[0012] The seat body is provided with a notch communicating with the cleaning chamber and the lower space of the seat body. In the assembled state, the expansion bottom shell extends from the notch into the lower space.

[0013] In this way, the internal space of the expansion bottom shell is connected to the inner cavity of the shell. When dirt is collected in the inner cavity of the shell, the dirt can enter the expansion bottom shell under the action of gravity. A slot is provided in the seat body so that the expansion bottom shell can be placed in the lower space of the seat body through the slot, thereby facilitating the volume of the expansion bottom shell and increasing the capacity of the expansion bottom shell. By providing the expansion bottom shell, the capacity of the filter assembly for dirt can be effectively increased, thereby reducing the frequency of the user cleaning the filter assembly and improving the user experience.

[0014] In one embodiment of the present invention, at least a portion of the shell wall of the expansion bottom shell is a filter screen made of nylon, and the filter screen and the expansion bottom shell are integrally injection molded.

[0015] In this configuration, since the nylon filter has good wear resistance, the reliability of the expansion bottom shell can be improved by making at least part of the shell wall of the expansion bottom shell a nylon filter. At the same time, since part of the water will flow into the filter assembly during the process of collecting dirt from the mopping member, at least part of the expansion bottom shell is set as a filter to separate the dirt from the water flow, so that the dirt is retained in the expansion bottom shell and the water flows out. In addition, by integrally injection molding the filter and the expansion shell, the expansion bottom shell can be reliably connected to the filter, and the manufacturing is simple and the cost is low.

[0016] In one of the embodiments of the present invention, a cover body fixed or integrally arranged relative to the base body is further arranged in the lower space of the base body, and the expansion bottom shell extending from the notch into the lower space is accommodated in the cover body.

[0017] In this way, by arranging the cover body on the seat body, it is possible to prevent water flowing out of the expansion bottom shell from entering the lower space of the seat body.

[0018] In one of the embodiments of the present invention, a snap-fitting piece is provided on the shell or the expansion bottom shell, and the filter assembly can be snap-fitted and fixed to the groove wall of the groove through the snap-fitting piece.

[0019] In this way, a snap fastener is provided through the shell or the expansion bottom shell so that the filter assembly can be detachably arranged on the seat body, thereby improving the convenience of the user in cleaning the filter assembly.

[0020] In one embodiment of the present invention, a protrusion is provided on the groove wall of the groove;

[0021] The snap fastener comprises an extension portion which is fixedly connected to the housing or the expansion bottom shell and can undergo elastic deformation, and the extension portion is provided with a step portion for snapping with the protrusion.

[0022] In this configuration, by providing an elastically deformable extension, when a force is applied to the extension, the extension deforms to drive the step portion to change its position, thereby causing the step portion to separate from the protrusion, thereby releasing the clamping fixation between the clip and the protrusion. In this way, the user only needs to squeeze the extension without using other tools to remove the filter assembly from the slot wall of the slot, further improving the convenience of use for the user.

[0023] In one embodiment of the present invention, the base station includes two groups of cleaning components, and each group of cleaning components corresponds to at least one filtering component.

[0024] In this configuration, two groups of cleaning members are arranged at the base station, and each group of cleaning members corresponds to at least one filter assembly, so that the base station can clean two mopping members at the same time, thereby improving the efficiency of the base station in cleaning the mopping members.

[0025] In one of the embodiments of the present invention, the dirt collecting holes are provided on both side walls of the shell along the direction in which the wiping member rotates and cleans in the cleaning bin, and at least one cleaning member is provided on each of the two circumferential sides of the filter assembly.

[0026] In this way, dirt collecting holes are opened on both side walls of the shell, and at least one cleaning member is arranged on both sides of the filter assembly in the circumferential direction during the cleaning process, so that when the wiping member rotates in two directions, the dirt from the two rotation directions of the wiping member can be scraped and collected respectively.

[0027] The present invention also provides a cleaning robot, which includes the base station mentioned above and a host cooperating with the base station.

[0028] In this way, by setting the cleaning robot at the base station, dirt on the mop can be removed and collected during the process of the base station cleaning the mop, thereby improving the effect of the base station cleaning the mop. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0044] With the continuous development of the cleaning robot technology field, cleaning robots have entered many ordinary households, effectively reducing people's housework burden. For some cleaning robots with mopping parts to achieve the mopping function, in order to reduce the trouble of users frequently changing and washing the mopping parts, the mopping parts need to be cleaned through a base station.

[0045] When the mop is cleaning the floor, it is very easy for cotton wool or solid particles on the floor to adhere to the mop. When the existing base station cleans the rotating mop, the dirt adhered to the mop will enter the sewage as the cleaning process proceeds. When the base station discharges this part of the sewage, the cotton wool and solid particles in the sewage are easy to clog the drainage pipe of the base station.

[0046] To solve this problem, some base stations are equipped with filters and other devices for filtering dirt at the sewage discharge position to prevent such dirt from being directly discharged with the sewage and clogging the drainage pipe. However, in this type of base station structure, since the dirt can only be filtered when the sewage is discharged, and the filtered dirt is still accumulated inside the base station, the dirt is likely to adhere to the mop again, seriously affecting the cleaning effect of the base station. Therefore, the base station with this structure requires the user to clean the dirt in the cleaning chamber in time, otherwise, the mop will bring the dirt back to the ground again.

[0047] In view of the above technical problems, it is necessary to provide a base station 10, which can collect the dirt in time while removing the cotton wool, solid particles and other dirt adhering to the mop 210, which not only avoids the dirt clogging the drainage pipe when discharging sewage, but also the user does not need to frequently deal with the dirt in the base station 10 and will not affect the cleaning effect of the mop 210 when it is used again.

[0048] like Figures 1 to 4 As shown, the present invention first provides a base station 10, including a base body 11, the base body 11 has a cleaning chamber 111 for cleaning the mopping member 210, along the direction of the mopping member 210 rotating in the cleaning chamber 111 for cleaning, the cleaning member 30 and the filter assembly 20 are sequentially arranged in the cleaning chamber 111.

[0049] Among them, Figure 5 As shown, the filter assembly 20 includes a shell 21 having an inner cavity, and the shell 21 is provided with at least one dirt collecting hole 212 connected to the inner cavity. The dirt collecting hole 212 is configured so that the dirt scraped off the wiping member 210 by the cleaning member 30 can enter the inner cavity of the shell 21 through the dirt collecting hole 212 and be collected.

[0050] The mopping member 210 usually completes mopping the ground by rotating. When the mopping member 210 needs to be cleaned, the mopping member 210 needs to enter the cleaning chamber 111 of the base station 10 and rotate. The rotating mopping member 210 contacts and scrapes the cleaning member 30 also located in the cleaning chamber 111. The dirt on the mopping member 210 will be scraped off by the cleaning member 30 and enter the water. The cleaning member 30 and the filter assembly 20 are arranged in sequence along the direction of the mopping member 210 rotating and cleaning in the cleaning chamber 111. In this way, the mopping member 210 first scrapes with the cleaning member 30 in the cleaning chamber 111, so that the dirt on the mopping member 210 is scraped off. There may also be some dirt that is thrown out due to gravity as the mopping member 210 rotates. These dirt can be thrown toward the direction of the filter assembly 20 under the action of centrifugal force, and then enter the inner cavity of the housing 21 through the dirt collecting hole 212 to be intercepted and collected.

[0051] In this way, dirt is collected by the filter assembly 20 as the mop 210 and the cleaning member 30 scrape and clean, and is directly retained in the inner cavity of the housing 21, so that the dirt will not be adhered to the mop 210 and taken out of the cleaning chamber 111 again, and the discharged sewage will not carry dirt that may block the drainage pipe. At the same time, the user only needs to clean the filter assembly 20 regularly to ensure that its inner cavity can accommodate dirt. In this way, not only can the dirt be effectively prevented from being scattered in the cleaning chamber 111, causing the mop 210 to adhere to the dirt again, thereby causing the base station 10 to have a poor cleaning effect on the mop 210, but also the cleaning efficiency of the base station 10 for the mop 210 is improved. Therefore, compared with the solution in the prior art that collects dirt again through the drainage link, this solution allows the mop 210 to be in a cleaner state after cleaning, thereby also ensuring the effect of the mop 210 cleaning the ground.

[0052] In other embodiments, the scraping member 210 may also be provided as a rotatable drum-type scraping member 210. Accordingly, the cleaning member 30 and the filter assembly 20 should be arranged in sequence along the rotation direction of the drum-type scraping member 210. The present invention does not limit the specific form of the arrangement of the cleaning member 30 and the filter assembly 20, as long as the dirt on the scraping member 210 can be scraped by the cleaning member 30 and then thrown into the filter assembly 20.

[0053] In one embodiment, a plurality of dirt collecting holes 212 are provided, and the plurality of dirt collecting holes 212 are evenly opened in the shell 21. Since the dirt enters the inner cavity of the shell 21 through the dirt collecting holes 212 under the action of centrifugal force, and the paths of dirt of different weights being thrown toward the dirt collecting holes 212 may be different, therefore, by increasing the number of dirt collecting holes 212, the distribution area of ​​the dirt collecting holes 212 on the shell 21 can be increased, so as to collect as much dirt as possible and avoid the dirt being unable to enter a single dirt collecting hole 212 due to movement path problems. At the same time, the plurality of dirt collecting holes 212 can allow dirt to enter the inner cavity of the shell 21, and also improve the efficiency of the filter assembly 20 in collecting dirt. It can be understood that the distribution position of the dirt collecting holes 212 on the shell 21 is set according to the path where the dirt scraped by the cleaning member 30 may be thrown out.

[0054] like Figure 6 to Figure 7 As shown, the filter assembly 20 further includes an expansion bottom shell 22 fixed relative to the housing 21 and having an internal space 221, and the internal space 221 of the expansion bottom shell 22 is communicated with the inner cavity of the housing 21. The seat body 11 may be provided with a notch 112 that connects the cleaning chamber 111 with the lower space 114 of the seat body 11. In the assembled state, the expansion bottom shell 22 extends from the notch 112 into the lower space 114.

[0055] The internal space 221 of the expansion bottom shell 22 is connected to the inner cavity of the shell 21. When dirt is collected in the inner cavity of the shell 21, the dirt can enter the expansion bottom shell 22 under the action of gravity. In this way, the capacity of the filter assembly 20 for dirt can be effectively increased, thereby reducing the frequency of cleaning the filter assembly 20 by the user, and improving the user experience. The seat body 11 is provided with a notch 112 so that the expansion bottom shell 22 is placed in the lower space 114 of the seat body 11 through the notch 112, so that it is easy to fully utilize the lower space 114 to increase the internal space 221 of the expansion bottom shell 22 and increase the internal volume of the expansion bottom shell 22.

[0056] In one embodiment, at least part of the shell wall of the expansion bottom shell 22 is a filter screen made of nylon material, and the filter screen and the expansion bottom shell 22 are integrally injection molded. Since part of the water flow will enter the filter assembly 20 when the filter assembly 20 collects the dirt from the mopping member 210, at least part of the expansion bottom shell 22 is set as a filter screen to separate the dirt from the water flow for solid-liquid separation, so that the dirt is retained in the expansion bottom shell 22 and the water flow flows out. The filter screen made of nylon material is not easy to be damaged and has high reliability because the nylon material has good wear resistance.

[0057] It is understandable that the present invention does not limit the area ratio of the shell wall of the expansion bottom shell 22 set to the nylon filter. The shell wall of the expansion bottom shell 22 can be set to the nylon filter in its entirety, or a part of the expansion bottom shell 22 can be set to the nylon filter. When the shell wall of the expansion bottom shell 22 is partially a nylon filter, the expansion bottom shell 22 and the nylon filter can be made by an integral injection molding process, so that the expansion bottom shell 22 is easy to manufacture and has a lower cost. It is understandable that since the expansion bottom shell 22 is fixed relative to the shell 21, and the internal space 221 of the expansion bottom shell 22 is connected to the inner cavity of the shell 21. Therefore, when the shell wall of the expansion bottom shell 22 is entirely a nylon filter, the nylon filter should be integrally injection molded with the shell 21.

[0058] like Figure 4 and Figure 7 As shown, a cover body 113 fixed relative to the base body 11 can also be provided in the lower space 114 of the base body 11, and the expansion bottom shell 22 extending from the slot 112 into the lower space 114 is accommodated in the cover body 113. Through the provision of the cover body 113, the water flowing out of the expansion bottom shell 22 can be temporarily retained in the cover body 113, and will not flow arbitrarily in the lower space 114. In other embodiments, the cover body 113 can also be formed in the lower space 114 in an integrated manner. In addition, the water retained in the cover body 113 can be cleaned by the user himself, or discharged into the sewage tank through an appropriate diversion structure or a built-in water pump of the base station 10.

[0059] The housing 21 or the expansion bottom shell 22 is provided with a snap-fitting piece 211, and the filter assembly 20 can be snap-fitted and fixed to the groove wall of the notch 112 through the snap-fitting piece 211. By providing the snap-fitting piece 211 on the housing 21 or the expansion bottom shell 22, the disassembly and assembly process between the filter assembly 20 and the seat body 11 can be facilitated, thereby improving the convenience of the user to clean the filter assembly 20.

[0060] like Figures 8 to 9 As shown, a protrusion 1121 is provided on the groove wall of the notch 112, and the clip 211 includes an extension portion 2111 fixedly connected to the housing 21 or the expansion bottom shell 22 and capable of elastic deformation, and the extension portion 2111 is provided with a step portion 2112 for engaging with the protrusion 1121. By providing the extension portion 2111 capable of elastic deformation, when a force is applied to the extension portion 2111, the extension portion 2111 is elastically deformed to drive the change of the position of the step portion 2112, thereby causing the step portion 2112 to be separated from the protrusion 1121, so as to release the engagement relationship between the clip 211 and the protrusion 1121. In this way, the user only needs to apply force to make the extension portion 2111 sufficiently elastically deformed, without using other tools, to remove the filter assembly 20 from the groove wall of the notch 112, further improving the convenience of use for the user.

[0061] like Figure 3 As shown, the base station 10 includes two groups of cleaning members 30, and each group of cleaning members 30 corresponds to at least one filter assembly 20. In order to improve the efficiency of the mopping and wiping members 210 in cleaning the floor, the same host 200 is usually provided with two or more mopping and wiping members 210. Therefore, by providing two groups of cleaning members 30 in the base station 10, and corresponding each group of cleaning members 30 to at least one filter assembly 20, the base station 10 can clean the two mopping and wiping members 210 at the same time, thereby improving the efficiency of the base station 10 in cleaning the mopping and wiping members 210.

[0062] Furthermore, along the direction of the mopping and wiping member 210 rotating and cleaning in the cleaning chamber 111, dirt collecting holes 212 are provided on both side walls of the housing 21, and at least one cleaning member 30 is provided on both sides of the filter assembly 20 in the circumferential direction. In this embodiment, in order to ensure the cleaning effect of the mopping and wiping member 210, when the mopping and wiping member 210 is placed in the cleaning chamber 111 for cleaning, it can be rotated in both clockwise and counterclockwise directions to scrape and clean with the cleaning member 30. The dirt collecting holes 212 are provided on both side walls of the housing 21, and at least one cleaning member 30 is provided on both sides of the filter assembly 20 in the circumferential direction during the cleaning process, so that when the mopping and wiping member 210 rotates in two directions, the dirt from the two rotation directions of the mopping and wiping member 210 can be scraped and collected respectively.

[0063] like Figure 10 to Figure 11 As shown, the present invention further provides a cleaning robot 100, which includes the above-mentioned base station 10 and a host 200 cooperating with the base station 10. By setting the above-mentioned base station 10 in the cleaning robot 100, the dirt on the mop 210 can be removed and collected during the process of the base station 10 cleaning the mop 210, thereby improving the effect of the base station 10 cleaning the mop 210.

[0064] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
