[0026] The specific embodiments of the scrubber of the utility model will be described below in combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 .

[0027] As shown in Figure 1 and Figure 4 , the utility model provides a kind of scrubber, comprising: body, body is provided with main machine 10, the lower portion of main machine 10 is formed with installation groove 20 towards the side of body, main machine 10 is provided with air inlet structure 11 and air outlet structure 12 in the side towards installation groove 20, negative pressure device integrated in main machine 10 guides gas from air inlet structure 11 to air outlet structure 12;Sewage tank 21, it is detachably installed in installation groove 20, in the installation state of sewage tank 21, the top air outlet of sewage tank 21 is communicated with air inlet structure 11, sewage tank 21 has structural clearance 22 between the inner side wall of installation groove 20, air outlet structure 12 is located in structural clearance 22.According to the scrubber of the utility model, by optimizing the design of air outlet path, it is realized to prevent sewage stain from adhering to the surface of body and power source 13, while avoiding the risk of sewage infiltration into electrical components.

[0028] Specifically, the scrubber utilizes the negative pressure device in the main machine 10 to suck the air in the sewage tank 21 into the air inlet structure 11 through the top air outlet, and then guide it to the air outlet structure 12 for discharge. Since the air outlet structure 12 is ingeniously arranged in the structural gap 22 between the sewage tank 21 and the inner side wall of the mounting groove 20, it not only effectively prevents the sewage from directly contacting the surface of the machine body when being discharged with the air, but also ensures that even if a small amount of water follows the airflow to the air outlet, it will be limited in the structural gap 22 and will not contact the electrical components at other positions of the machine body, thereby improving the safety and durability of the equipment, ensuring the cleanliness of the appearance of the scrubber, and improving the user experience.

[0029] It can be understood that the complete scrubber includes a cleaning head, a roller brush, a clean water tank, a control system and other components in addition to the machine body and the sewage tank 21. During the operation of the scrubber, the cleaning liquid in the clean water tank is delivered to the cleaning head through the pipeline, and after contacting the ground, it is removed by the high-speed rotation of the roller brush. At the same time, the sewage tank 21 collects the sewage mixed with stains through the suction force generated by the negative pressure device. During the entire cleaning process, the negative pressure device in the main machine 10 also sucks the air in the sewage tank 21 into the air inlet structure 11 through the top air outlet, and then guides it to the air outlet structure 12 in the structural gap 22 between the sewage tank 21 and the inner side wall of the mounting groove 20, thereby ensuring the cleaning efficiency and effectively preventing the sewage stains from adhering to the surface of the machine body and possibly penetrating into the electrical components. In addition, the control system is responsible for coordinating the working state of each component to ensure that the scrubber can stably and efficiently complete the cleaning task.

[0030] As shown in Figure 1 and Figure 2 , according to the scrubber of the utility model, the main machine 10 is provided with a power source 13, the power source 13 is located above the negative pressure device, and the power source 13 is isolated from the negative pressure device. Specifically, by placing the power source 13 above the negative pressure device and taking isolation measures, the mutual interference between the power source 13 and the negative pressure device can be effectively reduced. The isolation design of the power source 13 and the negative pressure device not only helps to prevent the sewage or moisture from penetrating upward from the negative pressure device to the power source 13 area, protects the power source 13 from the influence of the humid environment, prolongs its service life, but also reduces the influence of the heat and vibration generated by the power source 13 during work on the performance of the negative pressure device, and ensures the stable operation of the negative pressure device.

[0031] As shown in Figure 2 and Figure 3As shown, according to the utility model discloses a floor washing machine, negative pressure device includes: negative pressure chamber 31, be located below power source 13, the air inlet structure 11 set up between negative pressure chamber 31 and mounting groove 20, air guide duct 32, set up in one side of negative pressure chamber 31, and communicate in air outlet structure 12, negative pressure fan 33, set up in negative pressure chamber 31, for the gas in negative pressure chamber 31 is guided air guide duct 32. Specifically, negative pressure fan 33 when working will form strong suction in negative pressure chamber 31, through air inlet structure 11 and air in sewage tank 21 are sucked into negative pressure chamber 31. Subsequently, the gas is guided into air guide duct 32 by negative pressure fan 33, and finally is discharged through air outlet structure 12. Under the guidance of air guide duct 32, it is also helpful to reduce the risk of humidity and sewage into the power source 13 area, improve the safety and reliability of the floor washing machine. Air guide duct 32 can be arc-shaped, or be L-shaped channel shape with arc-shaped chamfer.

[0032] Further, according to the utility model discloses a floor washing machine, air guide duct 32 towards the air inlet end of negative pressure chamber 31 is provided with first sealing ring 34, and / or, air guide duct 32 towards the air outlet end of air outlet structure 12 is provided with second sealing ring 35. The first sealing ring 34 and / or second sealing ring 35 can enhance the sealing property between air guide duct 32 and negative pressure chamber 31 and air outlet structure 12, prevent leakage, ensure the effective operation of negative pressure device. At the same time, good sealing property can further reduce the possibility of humidity and sewage into the power source 13 area, enhance the safety and reliability of the floor washing machine.

[0033] Further, according to the utility model discloses a floor washing machine, the air inlet end of air guide duct 32 is provided with first one-way diaphragm 36, and first one-way diaphragm 36 only allows gas to flow from negative pressure chamber 31 to air guide duct 32. The role of first one-way diaphragm 36 is to ensure that the gas can only flow in one direction from negative pressure chamber 31 to air guide duct 32, and cannot flow in reverse. Can effectively avoid when the floor washing machine stops working or appears abnormal, the gas in air guide duct 32 flows back to negative pressure chamber 31.

[0034] Further, according to the utility model discloses a floor washing machine, the air outlet end of air guide duct 32 is provided with second one-way diaphragm 37, and second one-way diaphragm 37 only allows gas to flow from air guide duct 32 to the outside of air outlet structure 12. The role of second one-way diaphragm 37 is to ensure that the gas can only flow out of air guide duct 32 to the outside of air outlet structure 12, to prevent external air from flowing into air guide duct 32. Not only help to maintain the negative pressure state inside the floor washing machine, improve cleaning efficiency, but also can effectively avoid external dust and pollutants from flowing into the floor washing machine through air outlet structure 12, guarantee the cleanliness and service life of the equipment.

[0035] According to the scrubber, the negative pressure fan 33 is a centrifugal fan; the wind wall structure 38 surrounding the axial air inlet side of the negative pressure fan 33 is arranged in the negative pressure chamber 31; the inner side of the wind wall structure 38 forms an air inlet channel between the negative pressure fan 33 and the air inlet structure 11; and the height of the wind wall structure 38 is not higher than the radial air outlet side of the negative pressure fan 33. Specifically, the design of the wind wall structure 38 can concentrate and guide the airflow, so that the airflow can more effectively enter the negative pressure fan 33 through the air inlet structure 11, thereby enhancing the suction capacity of the negative pressure fan 33. At the same time, since the height of the wind wall structure 38 is controlled to be not higher than the radial air outlet side of the negative pressure fan 33, the airflow can be ensured to smoothly enter the air guide duct 32 from the radial air outlet side of the negative pressure fan 33, and the vortex or backflow phenomenon of the airflow near the negative pressure fan 33 is avoided, thereby further improving the flow efficiency and stability of the airflow. In summary, the wind wall structure 38 not only optimizes the airflow path, enhances the suction force, but also improves the working efficiency and safety of the entire negative pressure device.

[0036] As shown in Figure 4 According to the scrubber, the air inlet structure 11 is a mesh-shaped air inlet formed by a plurality of hollow hole structures. The mesh-shaped air inlet can be a grid composed of uniformly distributed small holes, which can not only ensure sufficient air inlet area, but also effectively filter out larger impurities to prevent large particles from entering the inside of the negative pressure chamber 31 and affecting the normal work of the negative pressure fan 33. The design of the mesh-shaped air inlet not only increases the uniformity of the air inlet and improves the air flow efficiency, but also facilitates cleaning and maintenance, ensuring the performance stability of the scrubber for a long time. In addition, by adjusting the size and density of the hollow holes, the air inlet amount can be flexibly optimized according to different use scenarios and requirements, thereby improving the adaptability and cleaning effect of the scrubber.

[0037] According to the scrubber, the inner side wall of the mounting groove 20 is an arc-shaped structure with a cross-sectional arc less than π. Specifically, the inner side wall of the mounting groove 20 forms an open semicircular or similar shaped space, which is beneficial to reduce the resistance of the airflow when passing through, promote the airflow to enter the structural gap 22 from the air outlet structure 12 more smoothly, and then discharge to the outside. In addition, the arc-shaped structure is also helpful to form a stable structural gap 22 between the sewage tank 21 and the mounting groove 20, ensure that the air outlet structure 12 is located in this gap, and facilitate the user to install and disassemble the sewage tank 21, improve the convenience of operation, and help to keep the inside of the scrubber clean and dry, prolong the service life of the equipment.

[0038] Further, according to the scrubber, the outer side surface of the sewage tank 21 is an arc surface matched with the inner side wall of the mounting groove 20; in the mounting state of the sewage tank 21, the structural gap 22 maintains uniform spacing at each position. A continuous and uniform structural gap 22 is formed between the sewage tank 21 and the inner side wall of the mounting groove 20. This uniform structural gap 22 not only facilitates uniform distribution of airflow, but also effectively prevents the problem of uneven pressure caused by excessive concentration of airflow in some positions. At the same time, the arc design of the outer side surface of the sewage tank 21 matches the arc structure of the inner side wall of the mounting groove 20, so that the installation and disassembly of the sewage tank 21 are more convenient and fast, and the aesthetic appearance and user experience are improved.
