Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship and movement status of various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] The present invention proposes a cleaning device, which can be a self-propelled mopping robot, a self-propelled scrubbing robot or a self-propelled washing and mopping machine. The cleaning device can also be a handheld mopping robot, a handheld scrubbing robot or a handheld washing and mopping machine, without specific limitation here.

[0039] Referring to Figures 1 and 2, the cleaning device 100 includes a housing 10, a roller brush 20, and a sprayer 30; a dirt suction chamber 10a is recessed at the bottom of the housing 10, and the housing 10 is further provided with a dirt suction channel 10b, which has a dirt inlet 10c and a dirt outlet 10d, the dirt inlet 10c being connected to the dirt suction chamber 10a, and the dirt outlet 10d being connected to the dirt storage container of the cleaning device; the roller brush 20 is rotatably mounted in the dirt suction chamber 10a and partially extends out of the dirt suction chamber 10a. A sprayer 30 is provided in the dirt suction chamber 10a. The sprayer 30 is used to spray cleaning liquid onto the roller brush 20. The sprayer 30 and the dirt inlet 10c are spaced apart in the rotation direction of the roller brush 20. A first baffle 40 is also provided in the dirt suction chamber 10a. The first baffle 40 is connected to the cavity wall of the dirt suction chamber 10a and is arranged parallel to the roller brush 20. The first baffle 40 is located between the sprayer 30 and the dirt inlet 10c in the rotation direction of the roller brush 20. The first baffle 40 is used to contact the roller brush 20.

[0040] The shape of the dirt suction chamber 10a is various. The outline of the dirt suction chamber 10a can be set in a cube shape, the outline of the dirt suction chamber 10a can also be set in a cylindrical shape, the outline of the dirt suction chamber 10a can also be a regular polygon, and the outline of the dirt suction chamber 10a can also be set in an irregular shape. I will not list them one by one here. Preferably, the internal outline of the dirt suction chamber 10a is set in a cylindrical shape. Such a setting can adapt to the shape of the roller brush 20 on the one hand, and facilitate the flow of fluid on the other hand.

[0041] It is worth noting that the position of the sewage inlet 10c is related to the rotation direction of the roller brush 20. When the roller brush 20 rotates relative to the housing 10, the roller brush 20 has a side that rotates from the inside of the sewage suction chamber 10a to the outside of the sewage suction chamber 10a, and the roller brush 20 also has a side that rotates from the outside of the sewage suction chamber 10a to the inside of the sewage suction chamber 10a. The sewage inlet 10c is located on the side where the roller brush 20 rotates from the outside of the sewage suction chamber 10a to the inside of the sewage suction chamber 10a. The sewage outlet 10d is connected to the sewage storage container of the cleaning equipment, and the sewage storage container of the cleaning equipment is pneumatically connected to the suction device of the cleaning equipment. The suction device of the cleaning equipment can drive air flow when it is working, thereby forming a negative pressure at the sewage inlet 10c and generating suction.

[0042] The sprayer 30 is a water-spraying structure that can be independent of the housing 10. The sprayer 30 can be a showerhead, a nozzle, or other structure. In this case, the sprayer 30 can be connected to the housing 10 in a variety of ways, such as screws, snaps, or welding. The sprayer 30 can also be integrated with the housing 10, in which case the sprayer 30 can be formed by a hole structure or a tube structure on the housing 10. The sprayer 30 can be connected directly to a container containing cleaning liquid, or it can be connected to the container containing cleaning liquid via a pipeline, without specific limitations here.

[0043] The first baffle 40 is fixedly connected to the cavity wall of the sewage suction chamber 10a. There are various ways to connect the first baffle 40 and the cavity wall of the sewage suction chamber 10a. The first baffle 40 and the cavity wall of the sewage suction chamber 10a can be connected by welding, screw connection, snap connection, and other methods, which are not specifically limited here. The first baffle 40 is set in an elongated strip shape as a whole, but the cross-section of the first baffle 40 has various shapes. The cross-section of the first baffle 40 can be set in a rectangular, triangular, elliptical, or other shapes, which are not specifically limited here. There are various materials to form the first baffle 40. The first baffle 40 can be made of plastic, metal, wood, rubber, and other materials, which are not specifically limited here.

[0044] The sprayer 30 and the sewage inlet 10c are arranged at intervals in the rotation direction of the roller brush 20, and the first baffle 40 is located between the sprayer 30 and the sewage inlet 10c in the rotation direction of the roller brush 20. When the roller brush 20 rotates from outside the sewage suction chamber 10a to inside the sewage suction chamber 10a, the roller brush 20 first passes through the position of the sewage inlet 10c, then passes through the position of the first baffle 40, and finally passes through the position of the sprayer 30. In this way, the sewage brought up by the rotation of the roller brush 20 can be blocked by the first baffle 40, and the garbage brought up by the rotation of the roller brush 20 can also be blocked. In addition, the garbage attached to the roller brush 20 can be scraped off by the first baffle 40. On the one hand, this avoids the garbage brought up by the roller brush 20 from being thrown into the sprayer 30, thereby causing the sprayer 30 to be blocked. On the other hand, it also ensures that the sewage and garbage brushed up by the roller brush 20 can be fully sucked into the sewage suction channel 10b, thereby improving the cleaning effect of the cleaning equipment.

[0045] It should be noted that the above-mentioned shell 10 can be composed of two parts, and can also be composed of three or more parts, which is not specifically limited here. In some embodiments of the present invention, please refer to Figures 1 to 3. The shell 10 includes a base 11 and an upper cover 12. The base 11 includes a main body 111 and two connecting arms 112. The two connecting arms 112 are located on the same side of the main body 111 in the horizontal direction. One end of the two connecting arms 112 is connected to the main body 111. The two connecting arms 112 extend along the horizontal direction and are arranged at intervals. At this time, the cross-section of the base 11 in the horizontal direction is roughly C-shaped, that is, at this time, the main body 111 and the two connecting arms 112 are arranged to form a semi-enclosed installation space. The upper cover 12 can be connected to the main body 111 and / or the two connecting arms 112. The upper cover 12, the main body 111 and the two connecting arms 112 are jointly arranged to form a sewage suction chamber 10a.

[0046] The roller brush 20 is arranged between the two connecting arms 112, and the two ends of the roller brush 20 in the axial direction are respectively rotatably connected to the corresponding connecting arms 112. Part of the roller brush 20 always extends from the open opening of the sewage suction chamber 10a, the sewage suction channel 10b is provided on the main body 111, and the sewage inlet 10c is provided on the side of the main body 111 adjacent to the two connecting arms 112. Since the sprayer 30 only needs to be located in the sewage suction chamber 10a, the sprayer 30 can be connected to the main body 111 and / or the upper cover 12. The first baffle 40 also only needs to be provided in the sewage suction chamber 10a, and at the same time, it can be located between the sewage inlet 10c and the sprayer 30 in the rotation direction of the roller brush 20. Therefore, the first baffle 40 can also be provided on the main body 111 and / or the upper cover 12.

[0047] It is worth noting that the upper cover 12 can be fixedly connected to the base 11. The upper cover 12 and the main body 111 and / or the two connecting arms 112 of the base 11 can be fixedly connected by screws, glue, etc. The upper cover 12 and the base 11 can be detachably connected. The upper cover 12 and the main body 111 and / or the two connecting arms 112 of the base 11 can be detachably connected by snap connections, screw connections, or other methods. Preferably, the upper cover 12 and the base 11 are detachably connected. Since the sewage suction chamber 10a is formed by the base 11 and the upper cover 12, the upper cover 12 and the base 11 are detachably connected, which facilitates cleaning of the walls of the sewage suction chamber 10a.

[0048] Based on the technical solution that the housing 10 is composed of a base 11 and an upper cover 12, in some embodiments of the present invention, the sprayer 30 is disposed on the main body 111. Specifically, referring to FIG2 , the main body 111 has a mounting wall 1111 facing the roller brush 20. The mounting wall 1111 is formed on the wall of the sewage suction chamber 10a. The sewage suction port is provided on the mounting wall 1111. The mounting wall 1111 also has a mounting groove 1112. The mounting groove 1112 is located above the sewage inlet 10c, and the sprayer 30 is mounted in the mounting groove 1112. This arrangement allows the sprayer 30 to be hidden within the wall of the sewage suction chamber 10a, thereby preventing the sprayer 30 from protruding from the wall of the sewage suction chamber 10a and contacting the roller brush 20, thereby preventing the sprayer 30 from being blocked by the roller brush 20. In addition, by arranging the sprayer 30 in the wall of the sewage suction chamber 10 a , the size of the sewage suction chamber 10 a can be reduced, which is beneficial for reducing the volume of the entire housing 10 .

[0049] It should be noted, referring to Figure 4, that when a water storage chamber 12a is provided on the upper cover 12, a water inlet channel is recessed upward on the groove wall of the mounting groove 1112 away from the sewage suction port, and the water inlet channel is connected to the sprayer 30. The upper cover 12 is also provided with a water outlet channel connected to the water storage chamber 12a. When the upper cover 12 is assembled to the base 11, the water outlet channel on the upper cover 12 is connected to the water outlet channel on the main body 111, which allows the cleaning liquid in the water storage chamber 12a to flow to the sprayer 30. Of course, valves can be provided on the water inlet channel and / or the water outlet channel to facilitate control of the supply of cleaning liquid to the sprayer 30.

[0050] Furthermore, the first baffle 40 has a connecting portion 41 and a scraping portion 42 arranged in sequence along the extension direction of the two connecting arms 112. The connecting portion 41 extends into the mounting groove 1112. The connecting portion 41 is located between the sprayer 30 and the groove wall of the mounting groove 1112 adjacent to the sewage inlet 10c. That is, the connecting portion 41 is fixed by clamping the sprayer 30 and the groove wall of the mounting groove 1112 adjacent to the sewage inlet 10c, and the scraping portion 42 is connected to the connecting portion 41 and extends out of the mounting groove 1112 to contact the roller brush 20.

[0051] With such a configuration, on the one hand, the installation of the sprinkler 30 and the first baffle 40 can be completed through one installation process, and on the other hand, the first baffle 40 is arranged adjacent to the sprinkler 30, which can also effectively prevent the roller brush 20 from contacting the sprinkler 30, thereby ensuring that the sprinkler 30 is not affected by the roller brush 20, and further ensuring that the sprinkler 30 can always keep spraying water smoothly.

[0052] It should be noted that when the connection portion 41 is clamped and fixed by the sprayer 30 and the wall of the mounting groove 1112 adjacent to the sewage inlet 10c, the connection portion 41 can be made of a flexible material, such as a flexible plastic, a rubber, or a silicone, which are not listed here. Since flexible materials have good deformability, when the sprayer 30 and the connection portion 41 are assembled together into the mounting groove 1112, the connection portion 41 can adapt to the gap between the sprayer 30 and the wall of the mounting groove 1112 adjacent to the sewage inlet 10c by deforming, which can further reduce the precision requirements of the mounting groove 1112.

[0053] Furthermore, the mounting wall 1111 is extended in the up-down direction, the two connecting arms 112 are connected to the mounting wall 1111, the sewage inlet 10c and the mounting groove 1112 are both provided on the mounting wall 1111, the mounting groove 1112 is located above the sewage inlet 10c, and the scraping portion 42 is extended in the vertical horizontal direction, that is, the scraping portion 42 is extended along the extension direction of the two connecting arms 112, and the scraping portion 42 is also inclined in the up-down direction, and the position of the scraping portion 42 adjacent to the roller brush 20 is lower than the position where the scraping portion 42 is connected to the connecting portion 41.

[0054] Because the scraping portion 42 extends in the direction of rotation of the roller brush 20, the roller brush 20 can rotate relative to the scraping portion 42, thereby facilitating the scraping portion 42 to scrape off garbage from the roller brush 20. The garbage scraped off by the scraping portion 42 falls downward under the action of gravity and eventually enters the sewage suction channel 10b through the sewage suction port. At the same time, because the scraping portion 42 is arranged in a vertically inclined manner, the sewage and garbage carried by the roller brush 20 will be thrown upward to the side of the scraping portion 42 adjacent to the sewage suction port and eventually flow downward. The sewage and garbage on the roller brush 20 will be scraped off by the scraping portion 42 and flow downward, thus causing both sewage and garbage to be sucked into the sewage suction channel 10b.

[0055] In addition, the cleaning liquid sprayed by the sprayer 30 flows along the scraping portion 42 toward the roller brush 20. This makes the cleaning liquid have a certain downward flow speed when it flows from top to bottom along the scraping portion 42 to the position where the scraping portion 42 contacts the roller brush 20. When the downward flowing cleaning liquid contacts the roller brush 20, it can flush the surface of the roller brush 20, which makes it easier to flush away all the garbage and sewage on the surface of the roller brush 20.

[0056] In some embodiments of the present invention, referring to Figures 2 and 5 , the housing 10 includes a base 11 and a top cover 12 removably mounted on the base 11. The top cover 12 and the base 11 together enclose a dirt suction chamber 10a. A second baffle 50 is further disposed within the dirt suction chamber 10a. The second baffle 50 is disposed parallel to the roller brush 20. One end of the second baffle 50 is connected to the surface of the top cover 12 facing the roller brush 20. The second baffle 50 is connected to the top cover 12 at a position on the side of the sprayer 30 away from the first baffle 40 in the direction of rotation of the roller brush 20. The other side of the second baffle 50 extends toward the first baffle 40 to separate the roller brush 20 from the sprayer 30, forming a water outlet gap between the second baffle 50 and the first baffle 40. This arrangement provides a second safety feature, further preventing trash from the roller brush 20 from being thrown onto the sprayer 30 and potentially clogging the sprayer 30.

[0057] It should be noted that the second baffle 50 and the upper cover 12 can be integrally formed. This configuration allows the second baffle 50 and the upper cover 12 to be injection molded using the same mold. This, on the one hand, reduces the number of parts in the entire cleaning device 100, and on the other hand, ensures the connection strength between the second baffle 50 and the upper cover 12. The second baffle 50 and the upper cover 12 can also be separate. When the second baffle 50 and the upper cover 12 are separate, the second baffle 50 and the upper cover 12 can be fixedly connected by screw connection, snap connection, welding, gluing, etc. Preferably, the second baffle 50 preferably adopts a detachable connection method, such as screw connection, snap connection, etc., so that the second baffle 50 can be replaced as an accessory.

[0058] It is worth noting that when the mounting wall 1111 is extended vertically, the notch of the mounting groove 1112 is opened horizontally, and the second baffle 50 can extend vertically. The second baffle 50 is spaced apart from or tangent to the side of the roller brush 20 adjacent to the mounting groove 1112. The second baffle 50 covers the notch of the mounting groove 1112, thereby completely separating the sprayer 30 from the roller brush 20. In addition, the second baffle 50 can serve as a transition structure between the mounting wall 1111 and the surface of the upper cover 12 facing the roller brush 20, thereby allowing air in the dirt suction chamber 10a to flow more smoothly from the surface of the second baffle 50 facing the roller brush 20 to the surface of the upper cover 12 facing the roller brush 20.

[0059] It should be noted that the water sprayed from the sprinkler 30 in the above embodiment flows out from the water outlet gap between the first baffle 40 and the second baffle 50. In other embodiments of the present invention, the first baffle 40 and the second baffle 50 are connected, and the first baffle 40 and / or the second baffle 50 are provided with a water outlet, which can be used for the water sprayed from the sprinkler 30 to flow out. The water outlet can be formed by a hole structure on the first baffle 40 or the second baffle 50, and the water outlet can also be formed by a hole structure formed by the first baffle 40 and the second baffle 50, which is not limited here.

[0060] Please refer to Figures 5 and 6 together. When the water outlet is provided on the second baffle 50, the water outlet is preferably provided at the side end of the second baffle 50 adjacent to the first baffle 40. Specifically, the side end of the second baffle 50 adjacent to the first baffle 40 is recessed with a plurality of notches 51, and the plurality of notches 51 are arranged in sequence along the extension direction of the roller brush 20. The plurality of notches 51 form water outlets. With such a configuration, the cleaning liquid sprayed from the sprayer 30 can flow along the side of the first baffle 40 adjacent to the sprayer 30 and flow to the roller brush 20 through the plurality of water outlets.

[0061] Furthermore, referring to FIG. 2 , a third baffle 60 is also disposed within the dirt suction chamber 10a. The third baffle 60 is arranged parallel to the roller brush 20. That is, the third baffle 60 extends axially along the roller brush 20 and is located on the side of the second baffle 50 away from the first baffle 40 in the direction of rotation of the roller brush 20. One side of the third baffle 60 is connected to the surface of the upper cover 12 facing the roller brush 20, and the other side of the third baffle 60 is in contact with the roller brush 20. This arrangement allows the second baffle 50, the third baffle 60, and the upper cover 12 to collectively enclose a dirt storage space. Waste on the roller brush 20 is scraped off by the third baffle 60 and stored in the dirt storage space between the second baffle 50 and the third baffle 60. Therefore, when cleaning the dirt suction chamber 10a, one only needs to remove the upper cover 12 from the base 11 and then clean out the waste in the dirt storage space.

[0062] It should be noted that the third baffle 60 and the upper cover 12 can be integrally formed. This configuration allows the third baffle 60 and the upper cover 12 to be injection molded using the same mold. This, on the one hand, reduces the number of parts in the entire cleaning device 100, and on the other hand, ensures the connection strength between the third baffle 60 and the upper cover 12. The third baffle 60 and the upper cover 12 can also be separate. When the third baffle 60 and the upper cover 12 are separate, the third baffle 60 and the upper cover 12 can be fixedly connected by screw connection, snap connection, welding, gluing, etc. Preferably, the third baffle 60 preferably adopts a detachable connection method, such as screw connection, snap connection, etc., so that the third baffle 60 can be replaced as an accessory.

[0063] Furthermore, please refer to Figures 5 and 7 together. A plurality of comb teeth 61 are provided on the side of the third baffle 60 away from the upper cover 12. The plurality of comb teeth 61 are arranged in sequence along the extension direction of the third baffle 60. The plurality of comb teeth 61 can extend into the interior of the roller brush 20 when in contact with the roller brush 20, so that the garbage on the surface of the roller brush 20 and the garbage inside the roller brush 20 can be cleaned in all directions. That is to say, although the garbage on the surface of the roller brush 20 is cleaned once by the first baffle 40, the garbage that is firmly stuck to the surface of the roller brush 20 and hidden inside the roller brush 20 can be cleaned out by the plurality of comb teeth 61 on the third baffle 60, so that the garbage on the roller brush 20 is cleaned, and the roller brush 20 can better clean the ground.

[0064] Furthermore, the third baffle 60 extends vertically, with the side of the third baffle 60 away from the upper cover 12 contacting the highest point of the roller brush 20. This arrangement, on the one hand, reduces the probability of debris scraped off the roller brush 20 by the third baffle 60 falling back onto the roller brush 20, and on the other hand, ensures that the volume of the dirt storage space is sufficiently large, thereby controlling the cleaning frequency of the dirt storage space within an appropriate range, thereby improving the user experience.

[0065] Furthermore, referring to Figures 2 and 5 , the suction chamber 10a is further provided with two side baffles 70 , which are spaced apart in the axial direction of the roller brush 20 . The side baffles 70 are connected to the upper cover 12 , and are respectively connected to the second baffle 50 and the third baffle 60 . The side baffles 70 , the second baffle 50 , and the third baffle 60 are arranged in an annular structure, with a waste storage space formed within the annular structure. This arrangement allows waste in the waste storage space to be simultaneously restrained by the second baffle 50 , the third baffle 60 , and the side baffles 70 , thereby preventing waste from leaking out of the waste storage space.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
