[0002] The wet cleaning device is generally used for wet cleaning of floors and tiles. The wet cleaning device is generally used for spraying cleaning liquid on a surface to be cleaned or a cleaning cloth, and then cleaning the surface to be cleaned, so that dirt is recycled into a sewage tank through the cleaning liquid.

[0003] In order to improve the cleaning efficiency, users generally add cleaning agents to the cleaning liquid. However, in some specific environments, it is not appropriate to use cleaning agents.

[0073] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0074] Referring to FIGS. 1-8, the present application discloses a wet cleaning device 100, which comprises a handle 2, a main body 1 connected with the handle 2, and a cleaning head 3 connected with the main body 1. A user can operate the wet cleaning device 100 through the handle 2 to realize the cleaning of the ground. The wet cleaning device 100 comprises a dirt recycling system. The dirt recycling system comprises a suction motor 107 for generating a suction airflow and a recycling bin 108 for recycling dirt. The suction airflow generated by the suction motor 107 recycles the dirt into the recycling bin 108. The wet cleaning device 100 further comprises a cleaning liquid supply system for directly or indirectly spraying cleaning liquid to the surface to be cleaned, the cleaning liquid supply system comprising a cleaning liquid tank and a water pump 112, the water pump 112 spraying the cleaning liquid in the cleaning liquid tank to the surface to be cleaned through a cleaning pipeline.

[0075] Referring to FIGS. 1-3, the main body 1 comprises a first end 101 and a second end 102 opposite to each other. The first end 101 is used to dock the handle 2, and the second end 102 is used to dock the cleaning head 3. The main body 1 comprises an outer shell 106, and the first end 101 of the outer shell 106 defines a first accommodating space 103. The main body 1 defines a third accommodating space for accommodating the recycling bin 108, and the third accommodating space is arranged between the first end 101 and the second end 102. The main body 1 is provided with the suction motor 107 and a battery pack 115 for providing power for the suction motor 107.

[0076] Referring to FIGS. 2 and 5, and also to FIG. 7, the first accommodating space 103 is provided with a circuit board 109 for controlling the wet cleaning device 100, the circuit board 109 being integrated with a main control board for controlling the wet cleaning device 100, a battery protection board for controlling the battery pack 115, and a display board for displaying information, the information displayed by the display board being visible through the light-transmitting material on the main body 1. In an embodiment, the uppermost end of the main body 1 is provided with a light-transmitting plate 114, through which the user can clearly see the information displayed by the display board. The main control board, the battery protection board, and the display board are integrated on the circuit board 109, which includes MCU, MOS, capacitors, resistors, and other components, and the developer only needs to connect the components according to the relevant functions, without any creative labor. Of course, the circuits on the various boards can also be directly integrated on one board, and the various functional components remain unchanged, which can reduce the cost of manufacturing multiple boards, effectively reduce the raw material cost and assembly cost, and at the same time, the circuit board 109 is installed on the first end 101 of the main body 1, which is close to the handle 2 and is less likely to contact liquid, thereby effectively protecting the circuit board 109.

[0077] In the prior art, the handle 2 is generally provided with a button 201, through which the user sends a control signal, and the control signal is transmitted to the circuit board 109 through a wire harness. The handle 2 is generally provided with a plug-in terminal for electrical connection with the main body 1. In this way, if there is liquid on the handle 2, the liquid can enter the space where the circuit board 109 is located along the wire harness, causing damage to the circuit board 109. In order to improve the waterproof performance of the first accommodating space 103, the handle 2 is provided with a wireless signal transmitter 202 for transmitting signals. The circuit board 109 is integrated with a wireless signal receiver 110 corresponding to the wireless signal transmitter 202. The wireless signal transceiver can be implemented by infrared pairs, and of course, other wireless signal transmission technologies such as Bluetooth technology and other optoelectronic technologies can also be used. In order to further reduce the cost, the circuit board 109 is also integrated with a motor control board for controlling the suction motor 107.

[0078] Referring to FIGS. 3-7, in a specific embodiment, the suction motor 107 and the battery pack 115 are both installed in the first accommodating space 103, the battery pack 115 is arranged above the suction motor 107 through a mounting bracket, and the circuit board 109 is arranged above the battery pack 115. The first end 101 is provided with a first cover 111 for sealing the first accommodating space 103. The suction motor 107, the battery pack 115, and the circuit board 109 are installed together in the first accommodating space 103, and then sealed by the first cover 111, which can achieve good sealing performance.

[0079] Referring to Figs. 6 and 8, the water pump 112 is also an electrical device, and if it is corroded, the cleaning device cannot be used normally. Therefore, the water pump 112 and other electrical devices also need a relatively good sealing environment. In order to realize the sealing of the structure of the water pump 112, the water pump 112 is arranged in the second containing space 104 defined by the second end 102. The second end 102 is provided with a second cover body 113 for sealing the second containing space 104, so that the second containing space 104 has a relatively good sealing effect. The lower end of the second cover body 113 is rotatably connected with the cleaning head 3.

[0080] Referring to Figs. 9-16, the cleaning liquid supply system further comprises a fluid detection device for detecting whether fluid flows in the fluid pipeline. The fluid detection device comprises an optical element 22, an optical structure 25 and a fluid detection controller 26. The fluid detection device is arranged in the mounting space 39. The fluid detection device is used to detect whether fluid flows in the fluid pipeline. The fluid detection device comprises an optical element 22, an optical structure 25 and a fluid detection controller 26. The optical element 22 generally consists of a light source 23 and a receiver 24. The optical structure 25 is generally a prism that can reflect and refract light. The light source 23 is used to emit light, and the receiver 24 is used to receive light and convert it into an electrical signal. The light source 23 is generally an LED or a fluorescent lamp, and the receiver 24 is generally a detector or a photosensitive sensor. At least part of the optical structure 25 is configured as part of the fluid pipeline. That is, the fluid flows through the surface of the optical structure 25. The fluid detection device is generally an optical liquid level sensor. The principle of the pipeline photoelectric liquid level sensor is based on the propagation and reflection characteristics of light. The height of the liquid level is determined by measuring the change in light intensity. When the liquid in the pipeline changes, the degree of absorption and reflection of light also changes, thereby changing the intensity of the light signal received by the receiver 24. By processing the received light signal, the light signal is converted into an electrical signal and sent to a data processing algorithm for processing and analysis. The height information of the liquid level can be obtained. The principle of optical liquid detection is also a commonly used detection technology, which will not be described here.

[0081] The cleaning liquid supply system further comprises an electrolytic water generating device for generating electrolytic water solution. The electrolytic water generating device is used to generate electrolytic water solution. Electrolytic ion water changes the pH value and oxidation-reduction potential of water through electrolysis. The principle of electrolytic water is prior art, which will not be described here. The electrolytic water generating device comprises an electrode sheet and an electrolytic water controller. At least part of the electrode sheet is arranged in the fluid pipeline. The electrode sheet comprises a first electrode sheet 16 and a second electrode sheet 17, which are respectively connected to the positive and negative electrodes of the power supply. When the power supply is turned on, the clean water will gradually become sterilizing liquid. The electrolytic water controller is used to control the conduction and cut-off of the circuit connected to the electrode sheet. The electrolytic water generating device is arranged in the second containing space 104.

[0082] Referring to FIGS. 9-16, the electrolysis water device 19 and the fluid detection device can be integrated into a functional assembly 10. In one embodiment, the functional assembly 10 includes a first housing 11 and a second housing 12, which together define a fluid path including a fluid inlet 14 and a fluid outlet 15. The optical structure 25 can be integrally formed with the second housing 12, and the optical structure 25 forms part of the fluid path with the inner wall of the first housing 11. The optical structure 25 can be integrally formed with the first housing 11, and the optical structure 25 forms part of the fluid path with the inner wall of the second housing 12. It is also possible that part of the optical structure 25 is integrally formed with the second housing 12, and another part of the optical structure 25 is integrally formed with the first housing 11, and the two parts form a passage therebetween. The fluid detection controller 26 and the electrolysis water controller 18 of the electrolysis water device 19 are integrated on the same circuit board 27. In this way, the optical structure 25 of the fluid detection device is integrated with the electrolysis water device 19, and they are integrally molded, which can reduce at least one set of molds, and also reduce the installation cost of each machine.

[0083] Referring to FIGS. 9-16, a functional assembly 10 is disclosed, which integrates an electrolysis water generating device and a fluid detection device. In one embodiment, the functional assembly 10 includes a first housing 11 and a second housing 12, which together define a flow region including a first region 28, a second region 29, and a third region 21 in fluid communication in sequence. The first region 28 is in fluid communication with the fluid inlet 14, and the third region 21 is in fluid communication with the fluid outlet 15. The optical structure 25 can be integrally formed with the second housing 12, and the optical structure 25 forms part of the fluid path with the inner wall of the first housing 11. In this way, the optical structure 25 of the fluid detection device is integrated with the electrolysis water generating device, and they are integrally molded, which can reduce at least one set of molds, and also reduce the installation cost of each machine.

[0084] The optical structure 25 is arranged in the first area 28, and the optical structure 25 can be integrally formed with the first shell 11. The optical structure 25 forms part of the fluid pipeline with the inner wall of the second shell 12. Alternatively, part of the optical structure 25 is integrally formed with the second shell 12, and the other part of the optical structure 25 is integrally formed with the first shell 11, and a channel is formed between the two. The second shell 12 is generally molded with a material having relatively good light transmission performance. The first electrode sheet 16 and the second electrode sheet 17 are arranged in the third area 21. When the functional assembly 10 is installed on the device, the first area 28, the second area 29, and the third area 21 are in a top-to-bottom positional relationship. In this way, the cleaning liquid flows from the first area 28 to the third area 21 gradually, and the fluid detection device can detect whether the cleaning liquid is supplied in the pipeline at the first time. The water pump 112 and the electrolytic water generating device (functional assembly 10) are installed at the lowermost end of the main body 1 (the position closest to the cleaning head 3), and the second containing space 104 is sealed. In this way, the center of gravity can be moved downward as much as possible, and the user experience of the user using the wet cleaning device can be improved.

[0085] The dirt recycling system further comprises a sewage detection device for detecting whether there is fluid flowing in the upper pipeline 35. The sewage detection device is installed in the upper pipeline 35. The sewage detection device comprises a transmitting element 31, a receiving element 32, and a sewage detection controller 33. When there is no dirt flowing in the suction pipeline 34, part of the light emitted by the transmitting element 31 is received by the receiving element 32. When there is dirt flowing in the suction pipeline 34, the dirt changes the direction of the light. At this time, the light received by the receiving element 32 changes, and the change in the light signal further causes a change in the electrical signal, so as to realize detection of the flow of dirt in the suction pipeline 34. One of the transmitting element 31 and the receiving element 32 is arranged on the circuit board 27, and the other is arranged opposite the suction pipeline 34. The sewage detection controller 33 is also arranged on the circuit board 27. At this time, the circuit board 27 integrates the controllers of the electrolytic water device 19, the fluid detection device, and the sewage detection device, achieving a three-in-one effect and further reducing costs. The arrangement of the electrical components on the circuit board 27 will not be described in detail here, and those skilled in the art can design them according to the relevant functions. In one embodiment, one of the transmitting element 31 or the receiving element 32 is integrated with the electrolytic water controller 18 on the same circuit board 27.

[0086] Further, the control board of the functional assembly 10 is installed on the second housing 12, and the control board is integrated with the controller of the electrolytic water generating device, the fluid detecting device and the sewage detecting device. The functional assembly 10 can be installed on the suction pipe 34 below the recycling tank 108. The sewage detecting device for detecting whether there is sewage flowing in the suction pipe 34 can also be arranged on the suction pipe 34. The sewage detecting device can also be integrated into the functional assembly 10. The sewage detecting device includes a transmitting element 31, a receiving element 32 and a sewage detecting controller 33, and the transmitting element 31 or the receiving element 32 is arranged on the circuit board 27. By integrating the electrolytic water generating device, the fluid detecting device and the sewage detecting device into one assembly, the material cost and the assembly cost can be effectively reduced.

[0087] With reference to FIGS. 9-16, the sewage detecting device, the fluid detecting device and the electrolytic water generating device 19 are integrated into the functional assembly 10 which is installed on the upper pipe 35. In this way, the material cost and the assembly cost can be further reduced. With reference to FIGS. 12 and 13, the first housing 11 and the second housing 12 are cuboid in shape, and of course, in other embodiments, they can be any other shape. The first housing 11 and the second housing 12 define a containing space therebetween, and the containing space can be used for fluid flowing. The fluid flows into the containing space from the fluid inlet 14 and flows out of the containing space from the fluid outlet 15. In order to ensure that the detection result of the fluid detecting device is relatively accurate, the optical structure 25 is arranged above the electrode sheet. Here, above does not mean directly above, but also means obliquely above. Because the two electrode sheets need to be soaked in the liquid when working, if the optical structure 25 is arranged below the position of the electrode sheet, the fluid detecting device will not alarm until the water in the area where the electrode sheet is located is consumed, which will cause a blank period of fluid supply, which is not desirable for users. By arranging the optical structure 25 above, the alarm signal can be generated in the first time when there is no fluid supply in the pipe.

[0088] Continuing to refer to FIGS. 9-16, as the electrolytic water device 19 is working, a large amount of bubbles will be generated, which will affect the detection result if they enter the area where the optical structure 25 is located. Therefore, the entire accommodating space is divided into three areas by the partition plate, and the partition plate is provided with a communication hole to facilitate the flow of fluid. The optical structure 25 is arranged in the first area 28, and the electrode sheet is arranged in the third area 21, and the second area 29 is arranged in between. The partition plate with a communication hole is arranged in the first area 28 and the second area 29 to ensure that the fluid in the first area 28 cannot quickly flow to the second area 29. The partition plate with a communication hole is arranged between the second area 29 and the third area 21 to avoid the bubbles in the third area 21 moving to the second area 29.
