[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0037] refer to Figure 1-8The present application discloses a wet cleaning device 100, comprising a handle 2, a main body 1 connected to the handle 2, and a cleaning head 3 connected to the main body 1. The user can operate the wet cleaning device 100 through the handle 2 to clean the floor. The wet cleaning device 100 includes a dirt recovery system. The dirt recovery system includes a suction motor 107 for generating a suction airflow and a recovery box 108 for recovering dirt. The suction airflow generated by the suction motor 107 recovers the dirt into the recovery box 108. The wet cleaning device 100 also includes a cleaning liquid supply system for directly or indirectly spraying a cleaning liquid onto a surface to be cleaned, the cleaning liquid supply system including a cleaning liquid tank and a water pump 112, the water pump 112 sprays the cleaning liquid in the cleaning liquid tank onto the surface to be cleaned through a cleaning pipeline.

[0038] refer to Figure 1-3 The main body 1 includes a first end 101 and a second end 102 opposite to each other. The first end 101 is used for docking with the handle 2, and the second end 102 is used for docking with the cleaning head 3. The main body 1 includes 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 a recycling box 108, and the third accommodating space is arranged between the first end 101 and the second end 102. A suction motor 107 and a battery pack 115 for providing power to the suction motor 107 are arranged in the main body 1.

[0039] refer to Figure 2 and 5 , you can also refer to Figure 7 , a circuit board 109 for controlling the wet cleaning device 100 is arranged in the first accommodating space 103, and the circuit board 109 is 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, and the information displayed on the display board is visible after passing through the light-transmitting material on the main body 1. In one embodiment, a light-transmitting plate 114 is arranged at the top of the main body 1, and the user can clearly see the information displayed on the display board through the light-transmitting plate 114. The main control board, the battery protection board and the display board are integrated into a circuit board 109, and the circuit board 109 includes components such as MCU, MOS, capacitors, resistors, etc. R&D personnel only need to compose circuits of various components according to relevant functions, and do not need to pay creative labor. Of course, the circuits on each board can also be directly integrated into one board, and the functional components remain unchanged. This can reduce the cost of manufacturing multiple boards separately, effectively reduce the cost of raw materials and assembly costs, and at the same time, the circuit board 109 is installed at the first end 101 of the main body 1. The first end 101 is close to the handle 2, which is rarely in contact with liquid, and can also effectively protect the circuit board 109.

[0040] In the prior art, the handle 2 is generally provided with a button 201, and the user sends a control signal through the button 201, and the control signal is transmitted to the circuit board 109 through the wiring harness. A plug-in terminal is generally provided in the handle 2, and is electrically connected to the main body 1 through the plug-in terminal. In this way, if there is liquid on the handle 2, the liquid may enter the space where the circuit board 109 is located along the wiring 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 an infrared pair of tubes. Of course, other wireless signal transmission can also be implemented, such as Bluetooth technology, other optoelectronic technologies, etc. In order to further reduce costs, the circuit board 109 is also integrated with a motor control board for controlling the suction motor 107.

[0041] refer to Figure 3-7 In a specific embodiment, the suction motor 107 and the battery pack 115 are both installed in the first accommodation space 103, the battery pack 115 is arranged above the suction motor 107 through the 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, and the first cover 111 is used to seal the first accommodation space 103. The suction motor 107, the battery pack 115 and the circuit board 109 are installed together in the first accommodation space 103, and then sealed by the first cover 111, so that a relatively good sealing performance can be achieved.

[0042] refer to Figure 6 and 8 Since the water pump 112 is also an electrical component, if it is corroded, the cleaning device cannot be used normally. Therefore, electrical components such as the water pump 112 also require a relatively good sealing environment. In order to achieve the sealing of the water pump 112 and other structures, the water pump 112 is arranged in the second accommodating space 104 defined by the second end 102. The second end 102 is provided with a second cover 113, and the second cover 113 is used to seal the second accommodating space 104, so that the second accommodating space 104 has a relatively good sealing effect. The lower end of the second cover 113 is rotatably connected to the cleaning head 3.

[0043] refer to Figure 9-13The wet cleaning device 100 also includes a clean water detection device, which is used to detect whether there is fluid flowing in the fluid pipeline. The clean water detection device includes an optical element, an optical structure 25 and a fluid detection controller. The clean water 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, and 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 will also change, thereby changing the intensity of the light signal received by the receiver. By processing the received light signal, the light signal is converted into an electrical signal and sent to the data processing algorithm for processing and analysis. The height information of the liquid level can be obtained. The optical liquid detection principle is also a relatively common detection technology, which will not be described in detail here. The optical element is usually composed of a light source and a receiver. The optical structure 25 is generally a prism-shaped structure that can reflect and refract light. The light source is used to emit light, and the receiver is used to receive light and convert it into an electrical signal. The light source is usually an LED or a fluorescent lamp, and the receiver is usually a detector or a photosensitive sensor. At least part of the optical structure 25 is constructed to form a part of the fluid pipeline. That is, the fluid flows through the surface of the optical structure 25 .

[0044] The cleaning liquid system also includes an electrolytic water generating device for generating an electrolytic water solution. The electrolytic water generating device is used to generate an electrolytic water solution, and the electrolytic ionized water changes the pH and redox potential of the water through electrolysis. The principle of electrolytic water is a prior art and will not be described in detail here. The electrolytic water generating device includes an electrode sheet and an electrolytic water controller. At least part of the electrode sheet is arranged in the fluid pipeline. The electrode sheet includes a first electrode sheet 16 and a second electrode sheet 17, and the two electrode sheets are respectively connected to the positive and negative poles of the power supply. When the power supply is turned on, the clean water will gradually become a sterilizing liquid. The electrolytic water controller is used to control the conduction and disconnection of the circuit connected to the electrode sheet. The electrolytic water generating device is arranged in the second accommodating space 104.

[0045] refer to Figure 9-13 , the figure discloses a functional component 10, which integrates an electrolytic water generating device and a clean water detection device. In a specific embodiment, the functional component 10 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 jointly define a flow area, and the flow area includes a first area 28, a second area 29 and a third area 21 that are fluidically connected in sequence. The first area 28 is fluidically connected to the fluid inlet 14, and the third area 21 is fluidically connected to the fluid outlet 15. The optical structure 25 can be integrally formed with the second shell 12, and the optical structure 25 and the inner wall of the first shell 11 form a partial fluid pipeline. In this way, the optical structure 25 of the clean water detection device is designed to be integrated with the electrolytic water generating device and molded as a whole, which can not only reduce at least one set of molds, but also reduce the installation cost of each machine.

[0046] 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, and the optical structure 25 and the inner wall of the second shell 12 form a part of the fluid pipeline. It is also possible that 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 with relatively good light transmittance. The first electrode sheet 16 and the second electrode sheet 17 are arranged in the third area 21. When the functional component 10 is installed on the device, the first area 28, the second area 29 and the third area 21 are in a positional relationship from top to bottom. In this way, the cleaning liquid gradually flows from the first area 28 to the third area 21, and the clean water detection device can detect whether there is a supply of cleaning liquid in the pipeline at the first time. Furthermore, due to

[0047] The control panel of the functional component 10 is mounted on the second housing 12, and a controller for controlling the electrolytic water generating device, the clean water detection device and the sewage detection device is integrated on the control panel. The functional component 10 can be mounted on the suction pipe 36 below the recovery box 108. The suction pipe 36 can also be provided with a sewage detection device for detecting whether there is sewage flowing in the suction pipe 36. The sewage detection device can also be integrated into the functional component 10. After the electrolytic water generating device, the clean water detection device and the sewage detection device are integrated into one component, the material cost and the assembly cost can be effectively reduced.

[0048] The water pump 112 and the electrolytic water generating device (functional component 10) are installed at the lowest end of the main body 1 (the position closest to the cleaning head 3), and the second accommodating space 104 is sealed. This can move the center of gravity downward as much as possible and improve the user experience of the user when using the floor scrubber.
