[0028] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs.

[0030] The present invention provides a cleaning machine. Figure 1 and Figure 3 As shown, the cleaning machine mainly includes a body 1, a cleaning head 3, a cleaning pipeline, a sewage detection component 11 and a control system.

[0031] The machine body 1 is provided with a sewage tank 2, a suction motor 5, a water pump (not shown), and a clean water tank (not shown). The suction motor 5 is connected to the sewage tank 2. When the suction motor 5 is activated, the sewage tank 2 is pumped into a negative pressure state. The sewage tank 2 is detachably connected to the machine body 1.

[0032] The cleaning surface of the cleaning head 3 is provided with at least a sewage inlet (not shown) and a clean water inlet (not shown). The cleaning circuit includes a clean water line (not shown) and a sewage line 4, which connects the sewage tank 2 and the sewage inlet. When the cleaning machine is in operation, the suction motor 5 is activated to draw sewage from the surface of the object 9 to be cleaned through the sewage inlet and sewage line 4 into the sewage tank 2.

[0033] The water pump is connected to the clean water tank and the clean water outlet through the clean water pipeline respectively. When the cleaning machine is working, the clean water in the clean water tank can be sprayed onto the surface of the object to be cleaned 9 through the clean water pipeline and the clean water outlet by the water pump, and then the surface of the object to be cleaned 9 can be cleaned with the help of an external cleaning tool or a cleaning head set on the cleaning head 3.

[0034] The outlet end of the sewage pipe 4 is connected to the water inlet of the sewage tank 2 through a transparent tube 10. The sewage detection component 11 is arranged on the outside of the transparent tube 10. The sewage detection component 11 can emit a detection light source into the transparent tube 10 and receive the emitted detection light source, and judge the turbidity of the sewage according to the parameter changes of the received detection light source.

[0035] The control system is electrically connected to the suction motor 5, the water pump and the sewage detection component 11 respectively. The control system can control the suction motor 5 and the water pump according to the turbidity of the sewage detected by the sewage detection component 11. Specifically, the operating gear of the cleaning machine can be adjusted by controlling the suction motor 5 to adjust the suction force, or by controlling the water pump to adjust other parameters such as the water spray flow rate. For example, when the turbidity of the sewage is large, the suction force of the suction motor 5 and the water spray volume of the water pump can be increased. It is easy to know that the suction force of the suction motor 5 and the water spray volume of the water pump corresponding to different operating gears of the cleaning machine are different.

[0036] In some embodiments, the cleaning head 3 may further include a brush head and a drive motor for controlling the rotation of the brush head. The brush head can be used to clean the surface of the object to be cleaned 9. A control system can also be connected to the drive motor to adjust the speed of the brush head based on the turbidity of the detected sewage. For example, when the sewage is relatively turbid, indicating that the surface of the object to be cleaned 9 is relatively dirty, the speed of the brush head can be increased to improve the cleaning speed and effectiveness.

[0037] Compared to traditional manual determination of soiling levels, the cleaning machine of this embodiment automatically senses the soiling level of the fabric being cleaned and autonomously adjusts the machine's operating gear based on the detected result, ensuring gentle cleaning for lightly soiled fabrics and heavy cleaning for heavier soiled fabrics, thereby improving cleaning efficiency and user experience. Furthermore, when the sewage tank 2 is removed, the user can conveniently clean the inner wall of the transparent tube 10, ensuring the detection effectiveness of the sewage detection assembly 11.

[0038] like Figure 3 As shown, in some embodiments, the sewage detection component 11 includes a light source emitting element 12, a light source receiving element 13 and a sewage detector (not shown in the figure) electrically connected to the light source emitting element 12 and the light source receiving element 13 respectively.

[0039] The light source emitting element 12 and the light source receiving element 13 are located on opposite sides of the transparent tube 10 . The light source emitting element 12 can emit a detection light source into the transparent tube 10 , and the light source receiving element 13 can receive the emitted detection light source.

[0040] The sewage detector is electrically connected to the control system. The sewage detector can determine the turbidity of the sewage based on changes in the parameters of the received detection light source and transmit the sewage turbidity information to the control system. Specifically, the sewage detector can use the principle of liquid blocking and absorbing light to detect the turbidity of the sewage in the sewage pipe 4.

[0041] Preferably, the transparent tube 10 of this embodiment is made of a highly transparent, light-transmitting material to facilitate detection of light source penetration.

[0042] Because the sewage of different turbidity levels in the sewage pipe 4 reacts very clearly to visible light, similar to the principle of human eyes seeing sewage, in some embodiments, the detection light source can use a white light source, so that all colors will have an impact on it, which can better distinguish between clear water and colored solutions, thereby identifying the degree of dirtiness.

[0043] In some embodiments, the cleaning machine further includes a waterproof box 14 for respectively enclosing the light source emitting element 12 and the light source receiving element 13 . The light source emitting element 12 and the light source receiving element 13 are respectively fixed in the corresponding waterproof box 14 .

[0044] The waterproof box 14 can be fixed to the body 1 by a common mechanical connection structure. The waterproof box 14 corresponding to the light source emitting element 12 and the light source receiving element 13 is open on one side facing the transparent tube 10, so as to facilitate the detection of light source emission and reception.

[0045] like Figure 2 As shown, in some embodiments, the cleaning machine further includes a flow guide box 6, which is detachably fastened to the cleaning surface of the cleaning head 3. When the flow guide box 6 is fastened to the cleaning surface of the cleaning head 3, the water pump and the suction motor 5 are respectively started, and the clean water sprayed from the clean water outlet can enter the flow guide box 6 and be sucked into the sewage tank 2 through the sewage outlet and the sewage pipe 4, thereby realizing the self-cleaning function of the cleaning machine.

[0046] In some embodiments, the diverter box 6 can also be movably mounted on the cleaning head 3, such as by being rotatably connected. The diverter box 6 can move relative to the cleaning head 3 to cover or expose the cleaning surface. When the cleaning machine is in cleaning mode, the diverter box 6 can be controlled to move relative to the cleaning head 3 to expose the cleaning surface, thereby cleaning the surface of the object to be cleaned 9; when the cleaning machine is in self-cleaning mode, the diverter box 6 can be controlled to move relative to the cleaning head 3 to cover the cleaning surface, thereby completing the cleaning of the sewage pipe 4.

[0047] As for the connection method between the guide box 6 and the cleaning head 3, the present invention does not make any specific limitation, and mechanical connection methods such as snap connection can be used.

[0048] In some embodiments, the diversion box 6 is a box structure with an open top. The diversion box 6 is buckled on the cleaning surface of the cleaning head 3 and covers the clean water outlet and the sewage outlet. The clean water spilled from the clean water outlet on the cleaning head 3 can directly enter the diversion box 6 and then be sucked into the sewage pipe 4 through the sewage outlet for cleaning, thereby improving the cleaning efficiency.

[0049] The open end of the guide box 6 has an annular sealing ring. When the guide box 6 is buckled on the cleaning surface of the cleaning head 3, the open end of the guide box 6 and the outer peripheral wall of the cleaning head 3 are sealed by the sealing ring to prevent leakage of cleaning water.

[0050] like Figure 1As shown, in some embodiments, the body 1 may be provided with a storage groove 8 for placing the sewage tank 2. The transparent tube 10 is located below the storage groove 8 and is placed vertically. The nozzle of the transparent tube 10 is located at the bottom of the storage groove 8, and the water outlet of the sewage tank 2 is located at the bottom of the tank. When the sewage tank 2 is placed in the storage groove 8, the water outlet of the sewage tank 2 is connected to the nozzle of the transparent tube 10, so that sewage can enter the sewage tank 2 through the transparent tube 10. At the same time, the nozzle of the transparent tube 10 is located at the bottom of the storage groove 8, which makes it convenient for the user to clean the transparent tube 10 when the sewage tank 2 is removed from the body 1.

[0051] In some embodiments, the cleaning machine further includes a cleaning brush (not shown in the figure), which is used to clean dirt on the inner wall of the transparent tube 10, and bristles are provided on the outer peripheral wall of the cleaning brush.

[0052] When the sewage tank 2 is separated from the body 1, the cleaning brush can be inserted into the transparent tube 10. By rotating the cleaning brush, the bristles on the brush can brush off the dirt on the inner wall of the transparent tube 10, thereby preventing the dirt on the inner wall from affecting the emission and reception of the detection light source of the sewage detection component 11.

[0053] In some embodiments, the cleaning head 3 of the cleaning machine may be provided with an indicator light 7 , and the indicator light 7 has a plurality of different colors of brightness, and each color represents the turbidity of a sewage.

[0054] For example, the sewage detector can determine several turbidity levels within the parameter range of the detection light source. Specifically, there are three levels of turbidity: light, medium, and heavy. The indicator light 7 is connected to the control system, and light, medium, and heavy levels correspond to different colors of indicator lights 7. When the sewage detector identifies the sewage as lightly polluted, the control system can control the indicator light 7 to display green; when the sewage detector identifies the sewage as medium polluted, the control system can control the indicator light 7 to display light red; when the sewage detector identifies the sewage as heavily polluted, the control system can control the indicator light 7 to display dark red. This allows users to easily monitor the cleaning status of the cleaning machine at all times.

[0055] In some embodiments, a transparent window may be provided at the front end of the cleaning head 3 for placing the indicator light 7 , thereby facilitating the user to observe the indicator light 7 .

[0056] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
