[0047] Embodiments of the present disclosure provide a cleaning system, such as Figures 1 to 6 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be a sweeping robot, a mopping robot, a sweeping-mopping robot, or the like; the cleaning device 10 can include a device body 11, a driving module 12, a sensing module 13, a control module 14, a cleaning module 15, an energy module 16, a human-machine interaction module 17, and the like. The base station 20 is used to dock the cleaning device 10, i.e., the cleaning device 10 can be parked on the base station 20, and the cleaning device 10 can perform functions such as charging, self-cleaning, parking, sewage discharge, and water replenishment on the base station 20.

[0048] In an embodiment, the device body 11 is configured to automatically move along a target direction on a travel surface, which can be a surface to be cleaned by the cleaning device 10. The cleaning device 10 can be a sweeping-mopping robot, and the cleaning device 10 works on the ground, which is the above-mentioned travel surface. The cleaning device 10 can travel on the ground by various combinations of movements relative to three mutually perpendicular axes defined by the device body 11: a fore-aft axis X, a lateral axis Y, and a central vertical axis Z. A forward driving direction along the fore-aft axis X is denoted as "forward", and a rearward driving direction along the fore-aft axis X is denoted as "rearward". The cleaning device 10 can rotate about the Y axis. When a forward portion of the cleaning device 10 is tilted upward and a rearward portion of the cleaning device 10 is tilted downward, it is "pitched up", and when the forward portion of the cleaning device 10 is tilted downward and the rearward portion of the cleaning device 10 is tilted upward, it is "pitched down". In addition, the cleaning device 10 can rotate about the Z axis. In the forward direction of the cleaning device 10, when the cleaning device 10 is tilted to the right side of the axis, it is "turned right", and when the cleaning device 10 is tilted to the left side of the Y axis, it is "turned left".

[0049] In an embodiment, the driving module 12 includes a driving wheel assembly 121, and the driving module 12 can simultaneously control the left wheel and the right wheel. In order to more accurately control the movement of the cleaning device 10, it is preferred that the driving module 12 includes a left driving wheel assembly and a right driving wheel assembly, respectively. The left and right driving wheel assemblies are symmetrically arranged along the lateral axis Y defined by the device body 11.

[0050] In an embodiment, as shown in Figure 3As shown, in order to make the cleaning device 10 more stable on the ground or more powerful movement ability, the cleaning device 10 can include one or more steering wheels 122; the steering wheel 122 can be a driven wheel, or a drive wheel, the structural form includes but is not limited to universal wheel, the steering wheel 122 can be located in front of the drive wheel assembly 121. The drive motor provides power for the drive wheel assembly 121 and / or the steering wheel 122.

[0051] In an embodiment, the perception module 13 includes a position determining device located above the device body 11, a bumper located at the front portion of the device body 11, a cliff sensor and an ultrasonic sensor located at the bottom of the device body 11, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, an odometer, and the like sensing device, providing various position information and motion state information of the device body 11 to the control module 14. For example, the front portion of the device body 11 is provided with a bumper, when the drive wheel assembly propels the cleaning device 10 to walk on the ground during the cleaning process, the bumper detects one or more events (or objects) in the travel path of the cleaning device 10 through the sensor module, such as an infrared sensor, the cleaning device 10 can control the drive structure to respond to the event (or object) by the event (or object) detected by the bumper, such as a step, an obstacle, a wall, for example, to climb over the step.

[0052] In an embodiment, the control module 14 can integrate distance information, speed information fed back by the bumper, the cliff sensor and the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, and the like to determine the current working state of the sweeper, such as climbing a step, passing a threshold, being on a carpet, being at a cliff, being stuck above or below, being full of dust box, being picked up, and the like, and give specific next action strategy for different situations, so that the working of the cleaning device 10 is more in line with the requirements of the owner, and has better user experience. Further, the control module 14 can plan the most efficient and reasonable cleaning path and cleaning method based on the real-time map information drawn by SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0053] In an embodiment, the energy module 16 includes a rechargeable battery, such as a nickel-hydrogen battery and a lithium battery. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit and a battery undervoltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit and the battery undervoltage monitoring circuit are connected with the single-chip microcomputer control circuit. The host is connected with the charging pile through the charging electrode arranged on the side or the lower side of the machine body for charging.

[0054] In an embodiment, the human-computer interaction module 17 includes keys on a host panel for a user to select functions; can also include a display screen and / or indicator lights and / or a loudspeaker to show the user the current state of the cleaning device 10 or the function selection item; and can also include a mobile phone client program. For path navigation type cleaning devices, the mobile phone client can show the user a map of the environment in which the cleaning device 10 is located, and the position of the cleaning device 10, and can provide the user with more abundant and humanized function items.

[0055] In an embodiment, the cleaning module 15 can include a dry cleaning module, or a dry and wet cleaning module. As shown in Figure 3 , the dry cleaning module can include a roller brush assembly 151, an edge brush 152, etc.; as shown in Figures 3 to 6 , the wet cleaning module includes a cleaning head 153, a water tank 19, etc. In an embodiment, the device body 11 is provided with a water injection nozzle 18, and the water injection nozzle 18 is formed with a water injection opening. By providing the water injection nozzle 18, the water injection opening is matched and connected with the base station 20, avoiding water leakage when water is injected through the water injection opening on the base station 20. Wherein, the water injection nozzle 18 is located on the side of the device body 11. As shown in Figure 6 , the water injection nozzle 18 is located on the mounting plate 110, that is, the water injection nozzle 18 is assembled on the mounting plate 110, or the water injection nozzle 18 is directly formed on the mounting plate 110.

[0056] In the related art, as shown in Figure 7 , one end of the water pipe 193' in the water tank is connected with the tank body 191', and the other end is connected with the tank cover 192'. When the water pipe 193' is connected with the tank body 191', a water replenishment opening support 195' is usually arranged between the tank body 191' and the water pipe 193' to facilitate the assembly of the water pipe 193'. Since the tank body 191', the tank cover 192' and the water replenishment opening support 195' are usually made of plastic material, the water replenishment opening support 195' is first connected with the tank body 191' by ultrasonic welding, and then the connection of the water pipe 193' with the water replenishment opening support 195' and the tank cover 192' is completed; then the tank cover 192' and the tank body 191' are connected together again by ultrasonic welding. However, when the tank cover 192' and the tank body 191' are ultrasonically welded for the second time, the water replenishment opening support 195' and the tank body 191' are easily shaken away from the position of the first ultrasonic welding, or the water replenishment opening support 195' and the tank body 191' are poorly welded during the first ultrasonic welding, which will both cause the water tank to have a risk of water leakage. In view of this, the embodiment of the present disclosure provides a water tank.

[0057] As shown in Figure 8 and Figure 9As shown, the water tank 19 comprises a tank body 191, a tank cover 192, and a first conduit 193. The tank body 191 is formed with a receiving portion 1914 having an opening 1915. The tank body 191 is provided with a liquid inlet hole 1910 communicating with the receiving portion 1914. The tank cover 192 is arranged on the opening 1915 of the tank body 191 and cooperates with the tank body 191 to form a receiving portion 1914 capable of accommodating a solution. The first conduit 193 comprises a first end and a second end. The inlet on the first end communicates with the liquid inlet hole 1910, and the first end is directly connected to the tank body 191. The second end is connected to the tank cover 192, and the outlet on the second end communicates with the receiving portion 1914.

[0058] When water is injected into the receiving portion 1914 of the water tank 19 through the liquid inlet hole 1910 of the water tank 19, the injected water can reach the tank cover 192 through the first conduit 193 and then flow into the receiving portion 1914 from the tank cover 192. Therefore, when the opening position on the tank body 191 is low due to structural limitations or other factors, the injected water can be injected into the receiving portion 1914 from a higher position close to the tank cover 192 through the first conduit 193, that is, more water or other solutions can be injected into the water tank 19 as much as possible. Further, since the first conduit 193 is directly connected to the tank body 191 without a support therebetween, the risk of water leakage of the water tank 19 caused by poor welding of the support and the tank body 191 during ultrasonic welding can be avoided. At the same time, the process of connecting the first conduit 193 to the tank body 191 does not use ultrasonic welding before the tank cover 192 and the tank body 191 are ultrasonically welded, thereby avoiding the support and the tank body 191 being shaken away from the ultrasonic welding position during ultrasonic welding of the tank cover 192 and the tank body 191, and improving the risk of water leakage of the water tank 19.

[0059] In an embodiment, as shown in Figure 8 and Figure 9 The tank body 191 comprises a tank wall and a first connector 1913. The tank wall and the first connector 1913 are formed with a through liquid inlet hole 1910. The first end of the first conduit 193 is connected to the first connector 1913. By providing the first connector 1913, the first end of the first conduit 193 can be connected to the tank body 191 through the first connector 1913, facilitating assembly between the first connector 1913 and the tank body 191, and improving the sealing performance of the first conduit 193 after being communicated with the liquid inlet hole 1910, thereby avoiding liquid leakage after the first conduit 193 is communicated with the tank body 191.

[0060] As shown in Figure 8 The first end of the first conduit 193 and the first connector 1913 can be connected in a plug-in manner, so that the inlet on the first end of the first conduit 193 communicates with the liquid inlet hole 1910 on the first connector 1913. After the first conduit 193 and the first connector 1913 are plugged in, the first end of the first conduit 193 can be directly connected to the tank body 191, and the second end of the first conduit 193 can be connected to the tank cover 192.Figure 8 The first end of the first conduit 193 is sleeved on the first connector 1913, so that the water injection is directly extended into the first conduit 193 through the first connector 1913, avoiding the water leakage between the inner wall of the first conduit 193 and the outer wall of the first connector 1913, thereby reducing the risk of water leakage between the first conduit 193 and the first connector 1913. In an embodiment, the first connector 1913 can also be sleeved on the first end of the first conduit 193 to realize the communication between the inlet on the first end of the first conduit 193 and the liquid inlet hole 1910 on the first connector 1913.

[0061] When the first end of the first conduit 193 and the first connector 1913 are connected in a plug-in manner, a sealant can be coated between the first end of the first conduit 193 and the first connector 1913 to improve the sealing performance between the first end of the first conduit 193 and the first connector 1913, avoid the first end of the first conduit 193 and the first connector 1913 from being shaken apart when the tank cover 192 and the tank body 191 are ultrasonically welded, and thereby avoid the water leakage between the first end of the first conduit 193 and the first connector 1913.

[0062] In an embodiment, the first connector 1913 and the tank wall are integrally formed, that is, the tank body 191 with the first connector 1913 on the tank wall can be directly formed by one-time injection molding process when the tank body 191 is formed, which can completely avoid the risk of water leakage between the first connector 1913 and the tank wall, and improve the connection strength between the first connector 1913 and the tank body 191. In another embodiment, the first connector 1913 and the tank wall can be sealed and connected together by adhesion, hot melting or the like.

[0063] As shown in Figure 8 and Figure 9 The tank body 191 includes a side wall 1911 and a bottom plate 1912, and the side wall 1911 and the bottom plate 1912 can be integrally formed. The first connector 1913 is arranged on the side wall 1911. In an embodiment, the first connector 1913 can extend on the side wall 1911 along the thickness direction of the side wall 1911 towards the containing portion 1914, so that after being connected with the first end of the first conduit 193, the first conduit 193 can avoid having a large bending angle at the position close to the first end, thereby reducing the bending angle of the first conduit 193, improving the stability of the connection between the first conduit 193 and the first connector 1913, and prolonging the service life of the first conduit 193.

[0064] As shown in Figure 9As shown, the liquid inlet hole 1910 is located on the side wall 1911 close to the bottom plate 1912. When water is injected into the containing portion 1914 of the water tank 19 through the liquid inlet hole 1910 of the water tank 19, due to the low position of the liquid inlet hole 1910, the water cannot be effectively injected into the water tank 19 directly through the liquid inlet hole 1910. By arranging the first conduit 193, the injected water can reach the tank cover 192 and then flow into the containing portion 1914 from the tank cover 192. Therefore, when the opening position of the liquid inlet hole 1910 on the tank body 191 is low due to structural limitations and other factors, the injected water can be injected into the containing portion 1914 from a high position close to the tank cover 192 through the first conduit 193, that is, more water or other solutions can be injected into the water tank 19 as much as possible.

[0065] In an embodiment, as shown in Figure 10 and Figure 11 As shown, the tank cover 192 is provided with a second connector 1921, which includes an inlet 19211 and an outlet 19212. The outlet 19212 of the second connector 1921 is in communication with the containing portion 1914, and the inlet 19211 of the second connector 1921 is connected with the second end of the first conduit 193. By arranging the second connector 1921, the second end of the first conduit 193 is connected to the side of the tank cover 192. The injected water can reach the tank cover 192 through the first conduit 193 and then flow into the containing portion 1914 from the tank cover 192. Therefore, when the opening position of the liquid inlet hole 1910 on the side wall 1911 is low due to structural limitations and other factors, the injected water can be injected into the containing portion 1914 from a high position close to the tank cover 192 through the first conduit 193, that is, more water or other solutions can be injected into the water tank 19 as much as possible.

[0066] In an embodiment, the second end of the first conduit 193 and the second connector 1921 can be connected in a plug-in manner, so that the outlet on the second end of the first conduit 193 is in communication with the inlet 19211 on the second connector 1921. After the first conduit 193 and the second connector 1921 are plugged in, the second end of the first conduit 193 is sleeved on the second connector 1921, and the second connector 1921 can also be sleeved on the second end of the first conduit 193, so that the inlet 19211 on the second end of the first conduit 193 is in communication with the liquid inlet hole 1910 on the second connector 1921.

[0067] When the second end of the first conduit 193 and the second connector 1921 are connected in a plug-in manner, a sealant can be applied between the second end of the first conduit 193 and the second connector 1921 to improve the sealing performance between the second end of the first conduit 193 and the second connector 1921, so as to avoid that the second end of the first conduit 193 and the second connector 1921 are shaken off when the tank cover 192 and the tank body 191 are ultrasonically welded.

[0068] In one embodiment, the second connector 1921 and the lid 192 are integrally molded, meaning that the lid 192 with the second connector 1921 can be directly formed through a single injection molding process, which improves the connection strength between the second connector 1921 and the lid 192. In another embodiment, the second connector 1921 and the lid 192 can be sealed together by means of bonding, heat fusion, or other methods.

[0069] like Figure 10 As shown, the second connector 1921 can extend along the thickness direction of the cover 192 towards the receiving portion 1914 on the cover 192. Therefore, after connecting with the second end of the first conduit 193, it can avoid the first conduit 193 from having a large bending angle near the second end, thereby reducing the bending angle of the first conduit 193 and improving the stability of the connection between the first conduit 193 and the second connector 1921, as well as the service life of the first conduit 193.

[0070] In one embodiment, after connecting the first end of the first conduit 193 to the first connector 1913 and the second end to the second connector 1921, ultrasonic welding can be used to seal the tank cover 192 and the tank body 191 together, forming a sealed receiving part 1914. The water tank 19 is made of a plastic material, which has advantages such as corrosion resistance, light weight, and long service life. Ultrasonic welding can ensure good sealing between the tank cover 192 and the tank body 191. In one embodiment, the tank cover 192 and the tank body 191 can be sealed together by means of bonding, heat fusion, etc.

[0071] Since the receiving part 1914 forms a sealed space, an exhaust hole 1923 can be provided on the cover 192 to avoid the situation where the pressure in the water tank 19 is too high when water is continuously poured into the water tank 19, which would prevent the water from being poured into the water tank 19. The exhaust hole 1923 can maintain the air pressure balance inside and outside the water tank 19, thereby ensuring that the water tank 19 can be filled with water.

[0072] In one embodiment, a one-way valve can be installed on the vent 1923. When the air pressure inside the water tank 19 exceeds a preset threshold, the one-way valve opens to release the gas inside the water tank 19, thereby reducing the air pressure inside the water tank 19 and allowing the water tank 19 to continuously fill with water until it is full. Furthermore, when the cleaning equipment 10 is in motion, it needs to perform operations such as overcoming obstacles and climbing steps. The one-way valve on the vent 1923 can prevent water from spilling out of the water tank 19 through the drain hole.
