[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0036] In the description of the present 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific situations.

[0037] Reference Figures 1-10, this application discloses a floor washer 100, which includes a cleaning head 2 and a main body 1 pivotally connected to the cleaning head 2. During use, the main body 1 can pivot around a pivot axis to facilitate user operation. The cleaning head 2 is used to clean the surface to be cleaned, and the cleaning head 2 defines a suction port. Generally, a roller brush is provided at the suction port. When the surface cleaning device is working, the presence of the roller brush can improve the cleaning efficiency. Of course, a roller brush may not be provided at the suction port, and a cleaning cloth or nothing can be provided instead. The floor washer 100 further includes a cleaning liquid supply system and a dirt recovery system. The cleaning liquid supply system includes a cleaning pipeline and a water pump 13 for pumping the cleaning liquid. The cleaning pipeline includes an electrolyzed water device 19 for generating an electrolyzed aqueous solution. The electrolyzed ionic water changes the pH value and redox potential of water through electrolysis. The principle of electrolyzed water is prior art and will not be elaborated here. The electrolyzed water device 19 includes electrode plates and an electrolyzed water controller 18. At least part of the electrode plates are disposed in the fluid pipeline. The electrode plates include a first electrode plate 16 and a second electrode plate 17, and the two electrode plates 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 bactericidal liquid. The electrolyzed water controller 18 is used to control the conduction and disconnection of the circuit connected to the electrode plates.

[0038] Reference Figure 2 and 3 , the dirt recovery system includes a suction motor 15 for generating a suction airflow and a recovery box 20 for recovering dirt. A suction pipeline 34 is provided between the recovery box 20 and the suction port. The suction pipeline 34 includes a lower pipeline 35 located at the cleaning head 2 and an upper pipeline 36 located at the main body 1. Among them, both the electrolyzed water device 19 and the water pump 13 are disposed around the upper pipeline 36. Setting the electrolyzed water device 19 and the water pump 13 at the lowest position of the main body 1, that is, the position closest to the cleaning head 2, can effectively prevent the liquid or water vapor from affecting the electrolyzed water device 19 and the water pump 13 when the user cleans the cleaning head 2. It can also make the center of gravity of the main body 1 move down as much as possible, as close to the cleaning head 2 as possible, making it more labor-saving for the user to use.

[0039] Reference Figure 3 , the main body 1 includes a main housing 37 and a docking housing 38 located below the main housing 37. The docking housing 38 is used to dock the cleaning head 2. An installation space 39 is defined between the main housing 37 and the docking housing 38, and both the electrolyzed water device 19 and the water pump 13 are disposed in the installation space 39. Sealing the periphery of the installation space 39 can more effectively protect the electrolyzed water device 19 and the water pump 13 disposed inside. The electrolyzed water device 19 is installed on the upper pipeline 36, and the electrolyzed water device 19 and the water pump 13 are disposed on opposite sides of the upper pipeline 36. In one embodiment, the electrolyzed water device 19 includes a first housing 11 and a second housing 12. The first housing 11 is installed on the upper pipeline 36, and the second housing 12 is installed on the first housing 11.

[0040] Reference Figures 4-10 Moreover, the cleaning liquid supply system further includes a fluid detection device for detecting whether there is fluid flowing through the cleaning pipeline. The fluid detection device includes an optical element 22, an optical structure 25, and a fluid detection controller 26. The fluid detection device is disposed in the installation space 39. The fluid detection device is used to detect whether there is fluid flowing through the fluid pipeline, and the fluid detection device includes 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 the light and convert it into an electrical signal. The light source 23 is usually an LED or a fluorescent lamp, and the receiver 24 is usually a detector or a photosensitive sensor. At least part of the optical structure 25 is configured as a part of the fluid pipeline. That is, when the fluid flows, it passes 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, and the height of the liquid level is determined by measuring the change in the intensity of light. When the liquid in the pipeline changes, the degree of absorption and reflection of light also changes, thereby changing the intensity of the optical signal received by the receiver 24. By processing the received optical signal, the optical 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 optical liquid detection principle is also a relatively commonly used detection technology, which will not be elaborated here.

[0041] Reference Figures 4-10 Moreover, the electrolyzer 19 and the fluid detection device can be integrated into a functional component 10. In a specific embodiment, the functional component 10 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 jointly define a fluid pipeline, and the fluid pipeline includes 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 and the inner wall of the first housing 11 form part of the fluid pipeline. The optical structure 25 can be integrally formed with the first housing 11, and the optical structure 25 and the inner wall of the second housing 12 form part of the fluid pipeline. It can also be 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 a channel is formed between the two. The fluid detection controller 26 and the electrolysis controller 18 of the electrolyzer 19 are integrated on the same circuit board 27. In this way, by integrating the optical structure 25 of the fluid detection device with the electrolyzer 19 and integrally molding them, not only can at least one set of molds be reduced, but also the installation cost of each machine can be reduced.

[0042] The dirt recovery system further includes a sewage detection device for detecting whether there is fluid flowing in the upper pipeline 36, and the sewage detection device is installed on the upper pipeline 36. The sewage detection device includes a transmitting element 31, a receiving element 32, and a sewage detection controller 33, and the sewage detection device is installed on the upper pipeline 36. 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 will change the direction of the light. At this time, the light received by the receiving element 32 will change. After the optical signal changes, it will further cause the electrical signal to change, so as to realize the detection of the dirt flow rate 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 to 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 electrolyzed water device 19, the fluid detection device, and the sewage detection device, achieving the effect of three-in-one and further reducing costs. The arrangement of the electronic control components on the circuit board 27 will not be described in detail here, and those skilled in the art can design it according to relevant functions. In one embodiment, one of the transmitting element 31 or the receiving element 32 is integrated with the electrolyzed water controller 18 on the same circuit board 27.

[0043] Continue to refer to Figures 4-10 , after the sewage detection device, the fluid detection device, and the electrolyzed water device 19 are integrated together, a functional component 10 is formed and installed on the upper pipeline 36. This can further reduce the material cost and installation cost. Referring to the figure, the first housing 11 and the second housing 12 in the figure are generally rectangular in shape. Of course, in other embodiments, they can also be of any other shape. A receiving space is defined between the first housing 11 and the second housing 12, and the receiving space can allow fluid to flow. The fluid flows into the fluid space from the fluid inlet 14 and flows out from the fluid outlet 15. In order to ensure that the detection result of the fluid detection device is relatively accurate, the optical structure 25 is arranged above the electrode plate. The above here does not specifically refer to directly above, and it can also be obliquely above. Because when the electrode plate is working, the two electrode plates need to be immersed in the liquid. If the position of the optical structure 25 is lower than that of the electrode plate, then only after the water in the area where the electrode plate is located is consumed, the fluid detection device will alarm, which will result in a blank period of fluid supply for a certain period of time, which is not what the user wants to see. By arranging the optical structure 25 above, when there is no fluid supply in the pipeline, an alarm signal can be generated in the first place.

[0044] Continue to refer to Figures 4-10, since a large number of bubbles are generated when the electrolyzed water device 19 is operating, if these bubbles enter the area where the optical structure 25 is located, it will affect the detection result. Therefore, the entire accommodation space is divided into three areas by a partition plate, and communication holes are provided at the partition plate to facilitate the flow of fluid. The optical structure 25 is arranged in the first area 28, and the electrode plate is arranged in the third area 21, with a second area 29 in between. Partition plates with communication holes are provided in the first area 28 and the second area 29 to ensure that the fluid in the first area 28 cannot flow quickly into the second area 29. A partition plate with a communication hole is provided between the second area 29 and the third area 21 to prevent the bubbles in the third area 21 from moving into the second area 29. That is to say, the fluid pipeline includes a first pipeline (the first area 28), a second pipeline (the second area 29), and a third pipeline (the third area 21) that are connected in sequence. The first pipeline is in fluid communication with the fluid inlet 14, and the third pipeline is in fluid communication with the fluid outlet 15. Figure 10 Taking the placement method of the middle housing as a reference, the vertical direction is the height direction. The first pipeline is arranged above the second pipeline, and the second pipeline is arranged above the third pipeline. At least part of the optical structure 25 is configured as a part of the first pipeline, and at least part of the electrode plate is arranged in the third pipeline.

[0045] Furthermore, to ensure the accuracy of the detection result, along the height direction, the fluid outlet 15 is lower than the fluid inlet 14 and higher than the position where the electrode plate is located.

[0046] Furthermore, to achieve the control of each device, the functional component 10 further includes a circuit board 27, and the circuit board 27 is installed on the second housing 12 or the first housing 11. To reduce the production cost and the installation space, the optical element 22, the electrolyzed water controller 18, and the fluid detection controller 26 are integrated onto the circuit board 27. In this way, the control elements (such as electronic components such as MCU, resistor, electrode, receiver 24, transmitter, etc.) of two or more devices are integrated on one circuit board 27 to form a complete control circuit. Figures 6-9 , in one embodiment, an optical structure 25 is integrated on the side of the second housing 12 facing the first housing 11, and an installation groove is defined on the other side of the second housing 12 for installing the circuit board 27. The optical element 22 on the circuit board 27 cooperates with the optical structure 25 to achieve the fluid detection function.

[0047] The functional component 10 further includes a sewage detection device, and the sewage detection device is used to detect whether there is sewage flowing in the suction pipeline 34. The sewage detection device includes a transmitting element 31, a receiving element 32, and a sewage detection controller 33, and the transmitting element 31 or the receiving element 32 is arranged on the circuit board 27.

[0048] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples herein.
