[0021] Reference Figure 1 , a wet cleaning device 100 is disclosed in the figure. The wet cleaning device 100 can be an upright vacuum cleaner, which includes a main body 1 and a cleaning head 2 movably connected to the main body 1. The wet cleaning device 100 can also be an autonomous wet cleaning device 100 (reference Figure 2 , Figure 2 shows a floor cleaning robot). The cleaning head 2 defines a suction port, and a rotatable roller brush around its own axis can be installed in the suction port, and other forms of wiping members can also be installed. Reference Figure 3, the wet cleaning device 100 further includes a dirt recovery system and a cleaning liquid supply system. The dirt recovery system includes a suction motor 11 for generating a suction airflow, a dirt recovery channel for guiding the suction airflow, and a recovery box 12 for accommodating dirt. The suction airflow sucks the dirt on the surface to be cleaned through the suction port into the recovery box 12. An air-liquid separation device, a solid-liquid separation device, etc. can be provided in the recovery box 12. The cleaning liquid supply system includes a cleaning liquid tank 13 for accommodating the cleaning liquid and a first supply pipeline 14 for directly or indirectly supplying the cleaning liquid to the surface to be cleaned. The dirt recovery channel includes a first channel 18 provided between the recovery box 12 and the suction port. Refer to Figure 3 and 4 , the first channel 18 is generally defined by an injection-molded connecting pipe 19. The connecting pipe 19 is used to connect the main body 1 and the cleaning head 2. The connecting pipe 19 can include a hard pipe and a flexible pipe, which cooperate with each other. The cleaning liquid supply system further includes a second supply pipeline 15 for supplying the cleaning liquid into the first channel 18.

[0022] The wet cleaning device 100 further includes a controller for controlling the opening / closing of the first supply pipeline 14 and for controlling the opening / closing of the second supply pipeline 15 according to different working modes of the wet cleaning device 100. The wet cleaning device 100 can include a dry suction mode (the dirt recovery system works and no cleaning liquid is sprayed on the surface to be cleaned), a cleaning mode (the dirt recovery system and cleaning liquid is sprayed on the surface to be cleaned at the same time), a self-cleaning mode (the wet cleaning device 100 is placed in the base station for self-cleaning), etc. The controller can control whether the first supply pipeline 14 and the second supply pipeline 15 work according to different working modes. The controller is generally a circuit board, and a variety of electrical components are integrated on the circuit board to form a control circuit. The user can send a control signal to the controller through a control button, and the controller controls each actuator of the wet cleaning device 100 according to the control signal. Controlling the components to perform related actions through the controller is a conventional technical means and will not be elaborated here.

[0023] Refer to Figure 8 , and can also refer to Figure 2-7 , in Figure 8In the illustrated embodiment, the first supply pipeline 14 and the second supply pipeline 15 are two independent pipelines. The first supply pipeline 14 includes a first pipeline 141 and a first water pump 142, and the second supply pipeline 15 includes a second pipeline 151 and a second water pump 152. The independence of the two pipelines means that the two pipelines can discharge water independently and do not rely on each other. The two pipelines can be respectively connected to the cleaning liquid tank 13, or can be connected to the cleaning liquid tank 13 through a tee structure. The second outlet 154 is arranged at a position of the first channel 18 close to the recovery tank 12. The second outlet 154 includes a plurality of liquid outlets 156, and the plurality of liquid outlets 156 are distributed along the circumferential direction of the first channel 18. Arranging a plurality of liquid outlets 156 along the circumferential direction can evenly spray the cleaning liquid into the first channel 18.

[0024] Reference Figure 5 and 6 , an annular channel is defined on the outer periphery of the connecting pipe 19, and a plurality of liquid outlets 156 are opened on the channel, and the cleaning liquid sprays the liquid into the first channel 18 through the liquid outlets 156. Of course, in other embodiments, the liquid outlets 156 can also exist in other forms.

[0025] When the wet cleaning device 100 is in the dry suction mode, the controller controls the dirty recovery system to work to recover the dirt on the surface to be cleaned. The dry suction mode is mainly used to suck some dirt without spraying the cleaning liquid onto the surface to be cleaned. At this time, the controller controls the first supply pipeline 14 not to work. During the cleaning process, the controller can control the second supply pipeline 15 to work or can control the second supply pipeline 15 not to work. When the second supply pipeline 15 works, since the suction motor 11 is working normally, the liquid provided by the second supply pipeline 15 will not flow to the surface to be cleaned under the action of the suction air flow, and the liquid sprayed by the second supply pipeline 15 will only clean the first channel 18.

[0026] When the wet cleaning device 100 is in the sweeping mode, while the dirty recovery system is working, the controller controls the first supply pipeline 14 to directly or indirectly spray the cleaning liquid onto the surface to be cleaned. To clean the inside of the first channel 18, the controller can control the second supply pipeline 15 to spray the cleaning liquid into the first channel 18, and the controller can control the second supply pipeline 15 to continuously or intermittently spray the cleaning liquid into the first channel 18.

[0027] When the wet cleaning device 100 is docked to the base station and during the self-cleaning process, the controller can control the second supply pipeline 15 to continuously or intermittently spray the cleaning liquid into the first channel 18 to improve the cleaning effect.

[0028] Reference Figure 4-7, To achieve intelligent design, the wet cleaning device 100 further includes a sewage detector 16 disposed outside the periphery of the first channel 18. The sewage detector 16 is used to detect the flow rate of sewage in the first channel 18. The sewage detector 16 is disposed at a position below the liquid outlet 156. The connecting pipe 19 is generally made of a transparent material through which light can pass. The sewage detector 16 is generally an optical element, which includes a light emitter 161 and a light receiver 162. When there is dirt flowing in the first channel 18, the light emitted by the light emitter 161 is blocked or deflected by the dirt, and the light received by the light receiver 162 changes. According to the change amount, the flow rate of dirt in the first channel 18 is determined. In the cleaning mode, the controller controls the opening / closing of the second supply line 15 according to the flow rate of sewage in the first channel 18. When the flow rate of sewage in the first channel 18 per unit time is less than a preset value, the opening of the second supply line 15 is controlled. A relatively small amount of sewage indicates that the inner wall of the first channel 18 is prone to adhering some dirt. Therefore, the amount of cleaning liquid in the first channel 18 is increased to improve the cleaning effect. When the flow rate of sewage in the first channel 18 per unit time is greater than the preset value, the closing of the second supply line 15 is controlled. When the amount of sewage is relatively large, most of the dirt can be sucked into the recovery box 12 along with the sewage and is not easily adhered to the side wall of the first channel 18. Therefore, it is not necessary to separately supply cleaning liquid to the first channel 18.

[0029] Reference Figure 5 and 6 , The second outlet 154 is located downstream of the position where the sewage detector 16 is located (downstream in the air flow direction). In this way, the inner wall of the first channel 18 can be cleaned to ensure the detection accuracy of the sewage detector 16.

[0030] Reference Figure 7 , In a further embodiment, the first supply line 14 further includes a germicidal liquid generator 20, and the second inlet 155 is located downstream of the liquid outlet 156 of the germicidal liquid generator 20. The germicidal liquid generator 20 can be an electrolyzed water generator, and of course, it can also be other forms of germicidal liquid generators 20.

[0031] Reference Figure 9 , At the same time, reference can also be made to Figure 3-7 , In Figure 9In the illustrated embodiment, the first supply line 14 includes a first line 141 and a water pump. The first line 141 is used to connect the cleaning liquid tank 13 and the liquid distributor located at the cleaning head 2. The water pump is used to pump the cleaning liquid in the cleaning liquid tank 13 through the first line 141 to the liquid distributor. The second supply line 15 includes a second line 151, a second inlet 155, a second outlet 154, and a second actuator 153 for controlling the on / off of the second line 151. The second line 151 is in fluid communication with the first line 141, and the second inlet 155 is located downstream of the liquid outlet 156 of the water pump. In this embodiment, the second supply line 15 cannot work independently. It must be controlled to spray the cleaning liquid into the first channel 18 when the first supply line 14 is working. When the first supply line 14 is not working, the second supply line 15 cannot work either.

[0032] Reference Figure 5 and 6 , an annular channel is defined on the outer periphery of the connecting pipe 19, and a plurality of liquid outlets 156 are provided on the channel. The cleaning liquid sprays the liquid into the first channel 18 through the liquid outlets 156. Of course, in other embodiments, the liquid outlets 156 may exist in other forms.

[0033] When the wet cleaning device 100 is in the dry suction mode, the controller controls the dirty water recovery system to work to recover the dirt on the surface to be cleaned. The dry suction mode is mainly used to suck some dirt without spraying the cleaning liquid onto the surface to be cleaned. At this time, the controller controls the first supply line 14 not to work, and at the same time, the second supply line 15 does not work.

[0034] When the wet cleaning device 100 is in the cleaning mode, while the dirty water recovery system is working, the controller controls the first supply line 14 to directly or indirectly spray the cleaning liquid onto the surface to be cleaned. To clean the inside of the first channel 18, the controller can control the second supply line 15 to spray the cleaning liquid into the first channel 18. The controller can control the second supply line 15 to continuously or intermittently spray the cleaning liquid into the first channel 18 while the first supply line 14 is working.

[0035] When the wet cleaning device 100 is docked to the base station and during the self-cleaning process, the controller can control the second supply line 15 to continuously or intermittently spray the cleaning liquid into the first channel 18 while the first supply line 14 is working to improve the cleaning effect.

[0036] Reference Figure 4-7, To achieve intelligent design, the wet cleaning device 100 further includes a sewage detector 16 disposed outside the periphery of the first channel 18. The sewage detector 16 is used to detect the flow rate of sewage in the first channel 18. The sewage detector 16 is disposed at a position below the liquid outlet 156. The connecting pipe 19 is generally made of a transparent material through which light can pass. The sewage detector 16 is generally an optical element, which includes a light emitter 161 and a light receiver 162. When there is dirt flowing in the first channel 18, the light emitted by the light emitter 161 is blocked or deflected by the dirt, and the light received by the light receiver 162 changes. According to the change amount, the flow rate of dirt in the first channel 18 is determined. In the cleaning mode, the controller controls the opening / closing of the second supply pipeline 15 according to the flow rate of sewage in the first channel 18. When the flow rate of sewage in the first channel 18 per unit time is less than a preset value, the second supply pipeline 15 is controlled to open. A relatively small amount of sewage indicates that the inner wall of the first channel 18 is prone to adhering some dirt. Therefore, the amount of cleaning liquid in the first channel 18 is increased to improve the cleaning effect. When the flow rate of sewage in the first channel 18 per unit time is greater than the preset value, the second supply pipeline 15 is controlled to close. When the amount of sewage is relatively large, most of the dirt can be sucked into the recovery box 12 along with the sewage and is not easily adhered to the side wall of the first channel 18. Therefore, it is not necessary to separately supply cleaning liquid into the first channel 18.

[0037] Referring to the figure, the second outlet 154 is located downstream of the position where the sewage detector 16 is located (downstream in the air flow direction). In this way, the inner wall of the first channel 18 can be cleaned to ensure the detection accuracy of the sewage detector 16 is guaranteed.

[0038] Reference Figure 7 , In a further embodiment, the first supply pipeline 14 further includes a germicidal liquid generator 20, and the second inlet 155 is located downstream of the liquid outlet 156 of the germicidal liquid generator 20. The germicidal liquid generator 20 can be an electrolyzed water generator, and of course, it can also be other forms of germicidal liquid generators 20.
