[0065] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0066] like Figures 1 to 3 As shown, according to the first aspect of an embodiment of the present application, a cleaning module is proposed, comprising: a shell 110, a sewage suction port 111 is formed on the shell 110; a cleaning member 120, the cleaning member 120 is arranged in the shell 110 and is rotatably connected to the shell 110; a nozzle 130, the nozzle 130 is connected to the shell 110, a sewage suction space 112 is formed between the cleaning member 120 and the shell 110, the output direction of the nozzle 130 is toward the sewage suction space 112, and the sewage suction port 111 is connected to the sewage suction space 112.

[0067] The cleaning module provided in the embodiment of the present application includes a shell 110, a cleaning member 120 and a nozzle 130. During use, the cleaning module can be moved on the surface to be cleaned, and the cleaning member 120 can be rotated to clean the surface to be cleaned. When the cleaning is completed and the cleaning module needs to be cleaned, the nozzle 130 can be opened to output the medium through the nozzle 130. The medium can flush the wall surface of the suction space 112, which can prevent dirt from accumulating in the dead corners of the suction space 112, and is conducive to the discharge of dirt through the suction space 112, thereby avoiding the growth of bacteria, improving the cleaning effect of the cleaning module next time, and improving the user experience.

[0068] It is understandable that the medium sprayed through the nozzle 130 can be liquid or gas, but considering that the suction space 112 uses airflow to discharge sewage when discharging sewage, if gas is output through the nozzle 130, the flow direction of the gas may be affected by the airflow of sewage discharge, so the medium sprayed through the nozzle 130 can be liquid. Further, in order to reduce costs, the medium sprayed through the nozzle 130 can be water.

[0069] like Figures 1 to 3 As shown, in a feasible implementation manner, the output direction of the nozzle 130 is toward the axial direction of the suction space 112 .

[0070] In this technical solution, an arrangement direction of the nozzle 130 is further provided, and the output direction of the nozzle 130 is toward the axial direction of the sewage suction space 112. When the nozzle 130 outputs the medium, the medium flow can be output along the axial direction of the sewage suction space 112, and the intersection area between the medium flow and the sewage suction space 112 is larger. The medium flow can better impact the inner wall of the sewage suction space 112, which can further improve the sewage discharge effect and reduce the probability of sewage accumulation in the sewage suction space 112.

[0071] On the other hand, considering that the suction space 112 usually discharges sewage through the middle of the suction space 112, the output direction of the nozzle 130 is toward the axial direction of the suction space 112. The medium flow direction output by the nozzle 130 can form a combined force with the suction direction of sewage discharge, which is more convenient for sewage discharge.

[0072] It is understandable that if Figure 1 As shown, Figure 1 The x direction is the axis direction.

[0073] It can be understood that there are multiple axes in the axial direction, and the nozzles can be arranged along any axis among the multiple axes.

[0074] like Figures 1 to 3 As shown, in a feasible implementation manner, the output direction of the nozzle 130 is toward the width direction of the suction space 112 .

[0075] In this technical solution, another arrangement of the nozzle 130 is further provided, in which the output direction of the nozzle 130 is toward the width direction of the suction space 112. This arrangement allows the medium flow output through the nozzle 130 to act on the wall surface of the suction space 112 as quickly as possible. When the medium flow contacts the inner wall of the suction space 112, it will have a greater impact force, which can further improve the sewage discharge effect and reduce the probability of dirt accumulating in the suction space 112.

[0076] It is understandable that if Figure 1 As shown, the y direction is the width direction.

[0077] like Figures 1 to 3 As shown, in a feasible implementation manner, there are two or more nozzles 130 .

[0078] In this technical solution, there may be two or more nozzles 130 , based on which the medium flow can be output through multiple nozzles 130 , which can better impact the dirt suction space 112 and reduce the probability of dirt residue.

[0079] In a feasible implementation, the plurality of nozzles 130 are arranged at intervals.

[0080] In this technical solution, when there are multiple nozzles 130, an arrangement method of the multiple nozzles 130 is provided, and the medium flow between the multiple nozzles 130 is not affected, the impact force of the medium flow can be guaranteed, and the impact effect on the remaining dirt is improved.

[0081] like Figures 1 to 3 As shown, in a feasible implementation manner, the plurality of nozzles 130 are divided into a plurality of groups, each group includes two nozzles 130, and the two nozzles 130 are arranged opposite to each other.

[0082] In this technical solution, when there are multiple nozzles 130, another arrangement method of the multiple nozzles 130 is provided. The multiple nozzles 130 are divided into multiple groups, each group includes two nozzles 130, and the two nozzles 130 are arranged opposite to each other. Such an arrangement can prevent the medium flow output through the nozzle 130 from impacting the dirt onto the wall of the suction space 112. The two nozzles 130 are arranged opposite to each other, so that the impacted dirt can be gathered between the two nozzles 130, which is convenient for the discharge of the dirt.

[0083] In a feasible implementation manner, the nozzle 130 is rotatably connected to the housing 110 .

[0084] In this technical solution, a connection method between the nozzle 130 and the shell 110 is further provided. The nozzle 130 is rotatably connected to the shell 110, so that the water flow output through the nozzle 130 can rotate relative to the shell 110, thereby increasing the coverage range of the liquid sprayed through the nozzle 130, and can better rinse the wall surface of the suction space 112, and can avoid the accumulation of dirt in the dead corner of the suction space 112, which is conducive to the discharge of dirt through the suction space 112, avoids the growth of bacteria, improves the cleaning effect of the next cleaning module, and improves the user experience.

[0085] like Figures 1 to 3 As shown, in a feasible embodiment, the cleaning module further includes: a scraper blade 140, which is connected to the housing 110 and extends toward the cleaning member 120, and the scraper blade 140 is used to scrape dirt on the cleaning member 120 away from the cleaning member 120 when the cleaning member 120 rotates.

[0086] like Figures 1 to 3 As shown, in a feasible embodiment, the cleaning module also includes: a scraper bar 150, which is connected to the shell 110 and is used to abut against the ground. The scraper bar 150 is used to extend toward the ground. The scraper blade 140, the scraper bar 150, the cleaning member 120 and the shell 110 enclose a dirt suction space 112.

[0087] In this technical solution, the structural composition of the cleaning module is further provided. The cleaning module may also include a scraper 140 and a scraper bar 150. During use, the cleaning member 120 rotates relative to the ground, and the scraper 140 contacts the cleaning member 120. The scraper 140 can remove dirt on the cleaning member 120, while the scraper bar 150 contacts the ground. Based on this, the scraper 140, the scraper bar 150 and the cleaning member 120 can be used to clean the surface to be cleaned by rotating the cleaning member 120, and the dirt can be discharged into the suction space 112, thereby improving the cleaning efficiency.

[0088] In a feasible implementation, the cleaning module further includes: a wheel body 160 , which is connected to the housing 110 and is located on a side of the housing 110 away from the cleaning member 120 ; and a driving assembly 170 , which is used to drive the cleaning member 120 to rotate.

[0089] In this technical solution, the cleaning module may further include a wheel body 160. The arrangement of the wheel body 160 may play an auxiliary role, facilitate the movement of the cleaning module, and enable the movement of the cleaning module to be more labor-saving.

[0090] like Figure 7 and Figure 8 As shown, Figure 8 The black frame in the middle is used to install the cleaning member 120. In order to better illustrate the setting position of the nozzle, the cleaning member 120 is hidden in the drawings. In a feasible implementation manner, there are two or more cleaning members 120.

[0091] In this technical solution, there may be multiple cleaning members 120, and the cleaning effect can be improved by having multiple cleaning members 120 contact the surface to be cleaned.

[0092] like Figure 7 and Figure 8 As shown, in a feasible implementation manner, when the axial directions of two or more cleaning members 120 are arranged coincident, the nozzle 130 is connected to the housing 110 and is located on one side of the cleaning member 120 .

[0093] In this technical solution, two or more cleaning members 120 can be arranged along the same axial direction, that is, multiple sections of cleaning members 120 are arranged in an axial direction, which can improve the cleaning efficiency. In this case, the nozzle 130 can be arranged on one side of the cleaning member 120. Such an arrangement allows the nozzle 130 to be located within the dirt suction space, so that the medium output by the nozzle 130 can be better sprayed onto the inner wall of the dirt suction space.

[0094] like Figure 7 and Figure 8As shown, in a feasible implementation manner, when two or more cleaning members 120 are arranged in parallel and at intervals, the nozzle 130 is connected to the housing 110 and is located between two adjacent cleaning members 120 .

[0095] In this technical solution, the cleaning members 120 are arranged in parallel and at intervals, and such an arrangement can also improve the cleaning efficiency. In this case, the nozzle 130 is located between two adjacent cleaning members 120, so that the nozzle 130 is in the dirt suction space, so that the medium output by the nozzle 130 can be better sprayed onto the inner wall of the dirt suction space.

[0096] In a feasible implementation manner, when there are two cleaning members 120 , the two cleaning members 120 rotate in different directions.

[0097] In this technical solution, when there are two cleaning members 120 , the two cleaning members 120 rotate in different directions. This arrangement can efficiently clean the stains on the surface to be cleaned and facilitates the transportation of the dirt into the dirt suction space 112 .

[0098] like Figure 7 and Figure 8 As shown, in a feasible implementation manner, when there are more than two cleaning members 120, the cleaning members 120 arranged in the same axial direction form a group of cleaning members, and the rotation directions of two adjacent cleaning groups are different.

[0099] In this technical solution, there may be more than two cleaning members 120. In this case, the cleaning members 120 may have a variety of arrangement methods. For example, there may be three cleaning members 120, two of which are arranged along the same axial direction, and the other cleaning member 120 is arranged parallel to the other two cleaning members 120. In this case, the cleaning members 120 with two coincident axes are a group of cleaning members, and the other cleaning member is another group of cleaning members. The two groups of cleaning members have different rotation directions, which can efficiently clean the stains on the surface to be cleaned and facilitate the transportation of dirt into the suction space 112.

[0100] It is understandable that there may be four cleaning members 120 , and the four cleaning members 120 are arranged in groups of two. The specific arrangement number of the cleaning members 120 is not limited in this application.

[0101] In this technical solution, a nozzle 130 is arranged between two adjacent cleaning members 120. Such an arrangement facilitates impacting the dirt suction space 112 of each cleaning member 120, thereby reducing the probability of dirt residue.

[0102] like Figures 4 to 9As shown, according to the second aspect of the embodiment of the present application, a cleaning device is proposed, including: a cleaning module as any of the above technical solutions; a body 210, the body 210 is used to be connected to the cleaning module and connected to the dirt suction space 112.

[0103] The cleaning device provided in the embodiment of the present application includes a cleaning module as described in any of the above technical solutions, and thus the cleaning device has all the beneficial effects of the cleaning module as described in any of the above technical solutions.

[0104] like Figure 6 As shown, during the use of the cleaning device provided by the embodiment of the present application, the cleaning module can be used to clean the surface to be cleaned, and the dirt will be collected in the dirt suction space 112 of the cleaning module. The body 210 can provide negative pressure to extract the dirt into the body 210. During the cleaning of the cleaning part 120 of the cleaning module, the nozzle 130 can be opened to output the medium through the nozzle 130. The medium can flush the wall surface of the dirt suction space 112, which can prevent the dirt from accumulating in the dead corner of the dirt suction space 112. The dirt is discharged into the body 210 through the dirt suction space 112. The dirt is uniformly stored through the body 210, which can prevent the growth of bacteria, improve the cleaning effect of the cleaning device next time, and improve the user experience.

[0105] like Figure 5 As shown, in a feasible embodiment, the body 210 includes: a casing 211, the casing 211 is used to be connected to the shell 110; a negative pressure piece and a negative pressure pipeline, the negative pressure piece is connected to the negative pressure pipeline, and the negative pressure pipeline is connected to the sewage suction space 112; a clean water tank body 221 212, the clean water tank body 221 212 is connected to the nozzle 130; a sewage tank body 213, the negative pressure pipeline is connected to the sewage tank body 213; a handle 214, and the handle 214 is connected to the casing 211.

[0106] In this technical solution, the structural composition of the body 210 is further provided. The body 210 may include a casing 211, a negative pressure part, a negative pressure pipeline and a sewage tank 213. During use, the negative pressure part can provide negative pressure, and the negative pressure acts on the sewage suction space 112 along the negative pressure pipeline. The casing 211 extracts the dirt in the sewage suction space 112. During this process, the clean water in the clean water tank can be output through the nozzle 130. The nozzle 130 can impact the sewage space, which can prevent dirt from accumulating in the dead corners of the sewage space, greatly reduce the probability of residual dirt, reduce the probability of bacterial growth, improve the cleaning effect, reduce the probability of odor, and improve user experience.

[0107] In a feasible embodiment, the fuselage 210 also includes: an output pipe, one end of the output pipe is connected to the clean water tank 221 body 212, and the other end is connected to the nozzle 130; a control valve, the control valve is arranged on the output pipe; and a pump body, the pump body is arranged in the clean water tank 221 body 212 and connected to the output pipe.

[0108] In this technical solution, the fuselage 210 may also include an output pipe, which is connected to the nozzle 130 to facilitate the spraying of water. A control valve is arranged on the output pipe to facilitate the control of the opening and closing of the nozzle 130. By arranging a pump body in the clean water tank, the clean water in the clean water tank can be pumped through the output pipe and then discharged through the nozzle 130, which can make the clean water flow have a certain impact force and improve the sewage discharge effect.

[0109] In a feasible embodiment, the cleaning device further includes: a booster valve, which is arranged on the output pipe. Such an arrangement allows the liquid to be output through the nozzle 130 at a higher flow rate when the liquid is output through the output pipe, so that the impact force of the medium output through the nozzle 130 is stronger, and the wall surface of the suction space 112 can be better washed, and the dirt can be prevented from accumulating in the dead corner of the suction space 112, which is conducive to the discharge of the dirt through the suction space 112, avoiding the growth of bacteria, improving the cleaning effect of the next cleaning module, and improving the user experience.

[0110] like Fig. 9 As shown, according to a third aspect of an embodiment of the present application, a cleaning system is proposed, comprising:

[0111] A cleaning device such as any of the above technical solutions; a base station 220, the base station 220 includes a clean water tank 221 or a water supply pipe, and the clean water tank 221 or the water supply pipe is connected to the nozzle 130.

[0112] In this technical solution, considering that the volume of the clean water tank on the fuselage 210 is limited, the clean water in the clean water tank also needs to be used to clean the surface to be cleaned, so it is not convenient to self-clean the cleaning element 120, which may cause the nozzle 130 to not have sufficient water output. Therefore, the cleaning equipment can also include a base station 220, and the base station 220 can also be equipped with a clean water tank 221. The clean water tank 221 can have greater convenience, and the clean water in the clean water tank 221 can be put into the self-cleaning of the cleaning element 120 and the water flow output of the nozzle 130, which can ensure the cleaning efficiency of the cleaning element 120, and at the same time ensure that the medium flow output through the nozzle 130 has a sufficiently large impact force to improve the cleaning effect.

[0113] In this technical solution, the base station 220 may also be provided with a water supply pipe. If the user has reserved a water supply pipe, the water supply pipe of the base station 220 may be directly connected to the user's water supply pipe, and clean water may be directly output through the water supply pipe. This clean water may be input into the self-cleaning of the cleaning element 120 and the water flow output of the nozzle 130, thereby ensuring the cleaning efficiency of the cleaning element 120 and ensuring that the medium flow output through the nozzle 130 has a sufficiently large impact force to improve the cleaning effect.

[0114] In a feasible embodiment, the cleaning device also includes: a first interface, the first interface is arranged on the shell 110 and is connected to the nozzle 130; a second interface is arranged at the end of the clean water tank 221 or the water supply pipe, and the second interface is used to connect to the first interface.

[0115] In this technical solution, the cleaning equipment may also include a first interface and a second interface. The first interface is opened on the shell 110 of the cleaning module and is connected to the nozzle 130 through a pipe, and the second interface is set on the clean water tank 221 or the water pipe. When the cleaning module is set in the base station 220, the first interface can be connected to the second interface. Based on this, clean water can be transported to the nozzle 130 through the clean water tank 221 or the water pipe, and the clean water can impact the suction space 112.
