[0032] refer to Figure 1 The figure discloses a wet cleaning device 100, which can be an upright vacuum cleaner, including a main unit 1 and a cleaning head 2 movably connected to the main unit 1. The wet cleaning device 100 can also be a self-contained wet cleaning device 100 (see reference). Figure 2 , Figure 2 (A robotic vacuum cleaner is shown in the image). The cleaning head 2 is defined with a suction port, within which a roller brush capable of rotating around its own axis can be installed, and other types of wiping components can also be attached. (Reference) Figure 3 The wet cleaning equipment 100 also includes a dirt recovery system and a cleaning fluid 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 tank 12 for containing dirt. The suction airflow draws dirt from the surface to be cleaned through the suction port into the recovery tank 12, which may be equipped with a gas-liquid separator, a solid-liquid separator, etc. The cleaning fluid supply system includes a cleaning fluid tank 13 for containing cleaning fluid and a first supply pipe 14 for directly or indirectly supplying the cleaning fluid to the surface to be cleaned. The dirt recovery channel includes a first channel 18 disposed between the recovery tank 12 and the suction port. (Reference) Figure 3 and 4 The first channel 18 is generally defined by an injection-molded connecting tube 19. The connecting tube 19 is used to connect the main unit 1 and the cleaning head 2. The connecting tube 19 may include a rigid tube and a flexible tube, which are coupled together. The cleaning fluid supply system also includes a second supply line 15 for supplying cleaning fluid into the first channel 18.
[0033] The wet cleaning device 100 also includes a controller, which controls the opening / closing of the first supply pipe 14 and the second supply pipe 15 according to different operating modes of the wet cleaning device 100. The wet cleaning device 100 may include a dry suction mode (the dirt recovery system operates, but cleaning liquid is not sprayed onto the surface to be cleaned), a sweeping mode (the dirt recovery system simultaneously sprays cleaning liquid onto the surface to be cleaned), and a self-cleaning mode (the wet cleaning device 100 performs self-cleaning after being placed on a base station), etc. The controller can control whether the first supply pipe 14 and the second supply pipe 15 operate according to different operating modes. The controller is generally a circuit board, which integrates various electrical components to form a control circuit. The user can send control signals to the controller via control buttons, and the controller controls the various actuators of the wet cleaning device 100 according to the control signals. Controlling components to perform related actions through the controller is a conventional technical means and will not be described in detail here.
[0034] refer to Figure 8 You can also refer to Figure 2-7 ,exist Figure 8 In 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 two pipelines are independent, meaning they can each output water independently and do not rely on each other. Both pipelines can be connected to the cleaning solution tank 13, or they can be connected to the cleaning solution tank 13 via a T-junction. The second outlet 154 is located in the first channel 18 near the recovery tank 12. The second outlet 154 includes multiple outlets 156, which are distributed circumferentially along the first channel 18. The circumferential arrangement of multiple outlets 156 allows for the uniform spraying of cleaning solution within the first channel 18.
[0035] refer to Figure 5 and 6 The outer periphery of the connecting pipe 19 defines an annular channel, and multiple liquid outlets 156 are provided on the channel. The cleaning liquid is sprayed into the first channel 18 through the liquid outlets 156. Of course, in other embodiments, the liquid outlets 156 may also exist in other forms.
[0036] When the wet cleaning device 100 is in dry suction mode, the controller activates the dirt recovery system to recover dirt from the surface to be cleaned. Dry suction mode is primarily used to extract dirt without spraying cleaning fluid onto the surface. In this mode, the controller disables the first supply line 14. During cleaning, the controller can either activate or deactivate the second supply line 15. When the second supply line 15 is activated, since the suction motor 11 is operating normally, the liquid supplied by the second supply line 15 will not flow towards the surface to be cleaned under the suction airflow; the liquid sprayed by the second supply line 15 will only clean the first channel 18.
[0037] When the wet cleaning equipment 100 is in cleaning mode, while the dirt recovery system is working, the controller controls the first supply pipe 14 to spray cleaning liquid directly or indirectly onto the surface to be cleaned. In order to achieve cleaning within the first channel 18, the controller can control the second supply pipe 15 to spray cleaning liquid into the first channel 18. The controller can control the second supply pipe 15 to continuously or intermittently spray cleaning liquid into the first channel 18.
[0038] When the wet cleaning equipment 100 is connected to the base station, during the self-cleaning process, the controller can control the second supply pipeline 15 to continuously or intermittently spray cleaning liquid into the first channel 18 to improve the cleaning effect.
[0039] refer to Figure 4-7 To achieve intelligent design, the wet cleaning equipment 100 also includes a wastewater detector 16 disposed on the outer periphery of the first channel 18. The wastewater detector 16 is used to detect the flow rate of wastewater in the first channel 18. The wastewater detector 16 is located below the outlet 156. The connecting pipe 19 is generally made of a transparent material that allows light to pass through. The wastewater detector 16 is generally an optical element, including 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. The flow rate of dirt in the first channel 18 is determined based on the amount of change. In cleaning mode, the controller controls the opening / closing of the second supply pipe 15 according to the flow rate of wastewater in the first channel 18. When the flow rate of wastewater in the first channel 18 per unit time is less than a preset value, the second supply pipe 15 is opened. A relatively small amount of wastewater indicates that some dirt easily adheres to the inner wall of the first channel 18. Therefore, increasing the amount of cleaning liquid in the first channel 18 improves the cleaning effect. When the flow rate of sewage in the first channel 18 per unit time exceeds a preset value, the second supply pipeline 15 is shut off. When the sewage volume is relatively large, most of the dirt can be drawn into the recovery tank 12 along with the sewage, and it is not easy to adhere to the side wall of the first channel 18. Therefore, it is not necessary to supply cleaning fluid separately to the first channel 18.
[0040] refer to Figure 5 and 6 The second outlet 154 is located downstream of the location of the wastewater detector 16 (downstream of the airflow direction). This allows the inner wall of the first channel 18 to be cleaned, ensuring the detection accuracy of the wastewater detector 16.
[0041] refer to Figure 7 In a further embodiment, the first supply line 14 also includes a disinfectant generator 20, and the second inlet 155 is located downstream of the outlet 156 of the disinfectant generator 20. The disinfectant generator 20 can be an electrolyzed water generator, or of course, other types of disinfectant generator 20.
[0042] refer to Figure 9 You can also refer to Figure 3-7 ,exist Figure 9 In the illustrated embodiment, the first supply line 14 includes a first line 141 and a water pump. The first line 141 connects the cleaning fluid tank 13 and the distributor located at the cleaning head 2. The water pump pumps the cleaning fluid in the cleaning fluid tank 13 to the distributor through the first line 141. The second supply line 15 includes a second line 151, a second inlet 155, a second outlet 154, and a second actuator 153 that controls the opening / closing of the second line 151. The second line 151 is fluidly connected to the first line 141, and the second inlet 155 is located downstream of the water pump outlet 156. In this embodiment, the second supply line 15 cannot operate independently; it can only be controlled to spray cleaning fluid into the first channel 18 when the first supply line 14 is operating. When the first supply line 14 is not operating, the second supply line 15 also cannot operate.
[0043] refer to Figure 5 and 6 The outer periphery of the connecting pipe 19 defines an annular channel, and multiple liquid outlets 156 are provided on the channel. The cleaning liquid is sprayed into the first channel 18 through the liquid outlets 156. Of course, in other embodiments, the liquid outlets 156 may also exist in other forms.
[0044] When the wet cleaning device 100 is in dry suction mode, the controller activates the dirt recovery system to recover dirt from the surface to be cleaned. Dry suction mode is primarily used to extract dirt without spraying cleaning fluid onto the surface. In this mode, the controller disables both the first supply line 14 and the second supply line 15.
[0045] When the wet cleaning equipment 100 is in cleaning mode, while the dirt recovery system is working, the controller controls the first supply pipe 14 to spray cleaning fluid directly or indirectly onto the surface to be cleaned. In order to achieve cleaning within the first channel 18, the controller can control the second supply pipe 15 to spray cleaning fluid into the first channel 18. The controller can control the second supply pipe 15 to continuously or intermittently spray cleaning fluid into the first channel 18 while the first supply pipe 14 is working.
[0046] When the wet cleaning equipment 100 is connected to the base station, during the self-cleaning process, the controller can control the second supply pipeline 15 to continuously or intermittently spray cleaning liquid into the first channel 18 while the first supply pipeline 14 is working, so as to improve the cleaning effect.
[0047] refer to Figure 4-7 To achieve intelligent design, the wet cleaning equipment 100 also includes a wastewater detector 16 disposed on the outer periphery of the first channel 18. The wastewater detector 16 is used to detect the flow rate of wastewater in the first channel 18. The wastewater detector 16 is located below the outlet 156. The connecting pipe 19 is generally made of a transparent material that allows light to pass through. The wastewater detector 16 is generally an optical element, including 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. The flow rate of dirt in the first channel 18 is determined based on the amount of change. In cleaning mode, the controller controls the opening / closing of the second supply pipe 15 according to the flow rate of wastewater in the first channel 18. When the flow rate of wastewater in the first channel 18 per unit time is less than a preset value, the second supply pipe 15 is opened. A relatively small amount of wastewater indicates that some dirt easily adheres to the inner wall of the first channel 18. Therefore, increasing the amount of cleaning liquid in the first channel 18 improves the cleaning effect. When the flow rate of sewage in the first channel 18 per unit time exceeds a preset value, the second supply pipeline 15 is shut off. When the sewage volume is relatively large, most of the dirt can be drawn into the recovery tank 12 along with the sewage, and it is not easy to adhere to the side wall of the first channel 18. Therefore, it is not necessary to supply cleaning fluid separately to the first channel 18.
[0048] Referring to the diagram, the second outlet 154 is located downstream of the wastewater detector 16 (downstream of the airflow direction). This allows for cleaning of the inner wall of the first channel 18, ensuring the detection accuracy of the wastewater detector 16.
[0049] refer to Figure 7In a further embodiment, the first supply line 14 also includes a disinfectant generator 20, and the second inlet 155 is located downstream of the outlet 156 of the disinfectant generator 20. The disinfectant generator 20 can be an electrolyzed water generator, or of course, other types of disinfectant generator 20.
