Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, specifically to the field of floor scrubber technology of a float system and its application. Background Technology
[0002] In the field of modern cleaning equipment, floor scrubbers, as a highly efficient floor cleaning tool, are widely used in various environments, from large industrial facilities to small home settings. To prevent wastewater from overflowing into the machine due to excessively high water levels during use, which could cause equipment damage or performance degradation, float valves are commonly used as an anti-overflow mechanism.
[0003] This traditional float design involves placing a float near the air intake in a cage. When the water level in the tank is low, the float naturally droops, allowing air to pass smoothly through the air intake. As the water level rises, the float rises and eventually blocks the air intake, preventing sewage from rising further and thus protecting the equipment from damage.
[0004] However, the need for a specialized float cage to ensure the float can float freely and stay in position increases the system's complexity. Secondly, traditional float designs are better suited for larger industrial floor scrubbers with ample water tank capacity; these devices typically have sufficient space to accommodate additional components. In contrast, in the application scenarios of small household or portable floor scrubbers, due to their smaller size and limited internal space, traditional float systems become unsuitable because of their large size and space requirements. Summary of the Invention
[0005] In response to the aforementioned needs, this application proposes a float ball system and a floor scrubber with the same application, aiming to overcome the shortcomings of the prior art as described above. By designing a new float ball system and an exhaust system that connects with it, the two systems are coaxially connected, which can reduce the space occupied by the machine body and realize the miniaturization and lightweighting of the floor scrubber.
[0006] To achieve the above objectives, the present application adopts the following technical solution:
[0007] In one aspect, this application provides a float system that is coaxially connected to an exhaust system installed on a chassis and built into a sewage tank;
[0008] It includes, from top to bottom, a top cover, a T-shaped tube, a float, and a ventilation pipe;

The outer periphery of the horizontal part is provided with multiple air intake ports, and the lower end of the vertical part is fitted over the upper end of the ventilation pipe.
[0010] The floating ball is a ring structure which can be sleeved into the vertical part and the ventilation pipe and can be guided to move, and the floating ball can block the air suction port when moving upward.
[0011] In this way, the floating ball system adopts a compact design concept, and all components, including the top cover, T-shaped pipe, floating ball and ventilation pipe, are ingeniously integrated in the sewage tank and coaxially connected with the air suction system installed on the chassis. This design not only greatly saves space, making the entire system suitable for installation in small equipment with limited space, but also simplifies the overall structure, reducing unnecessary complexity and potential failure points.
[0012] The floating ball adopts a ring structure design, which can be directly sleeved into the vertical part of the T-shaped pipe and the ventilation pipe and can be freely guided to move in the vertical direction, ensuring the effectiveness of the anti-overflow function while reducing the volume of the system and improving the space utilization.
[0013] In some possible embodiments, the air suction port is 6, evenly distributed on the outer periphery of the horizontal part.
[0014] In some possible embodiments, the ventilation pipe passes through the rubber gasket and the opening at the bottom of the sewage tank in sequence from bottom to top and is fixedly connected to the sewage tank.
[0015] In the second aspect, the application also provides a scrubber applying the floating ball system as described above, the scrubber comprising a chassis and an air suction system installed on the chassis, and the air suction system and the floating ball system are coaxially connected through a reverse buckle silica gel ring.

Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.
[0032] Please refer to Figure 1 and Figure 2 This is an overall schematic diagram of a floor scrubber with a suction system and its application, as described in this application. The chassis 100 has a body 200 at its upper end, and wastewater tanks 300 are located at the front and sides of the body 200. A scrubbing mechanism 400 is located at the bottom of the chassis 100. Please refer to the reference. Figure 4 The upper end of the chassis 100 is provided with an exhaust system 2 and a float system 1. The exhaust system 2 and the float system 1 are coaxially connected, and the float system 1 is built into the sewage tank 300.
[0033] Please refer to the reference. Figure 5 The chassis 100 is a concave cuboid formed by die-casting of aluminum, and has an extended skirt 110. This design allows the chassis 100 to be lightweight while also providing strong shear strength, enabling it to support the entire machine body 200. A pivot 510 for connecting the rear main wheel 500 is located through the skirt 110.
[0034] Further, please refer to Figure 2 and Figure 3 The bottom of the chassis 100 is provided with a shovel head mechanism 400, which includes a shovel body 410 and a swing arm 420 whose lower end is connected to the shovel body 410 and whose upper end is connected to the shaft 510 of the rear main wheel 500. An auxiliary wheel 430 is installed on each of the two rear sides of the shovel body 410, and anti-collision guide wheels 440 are installed on both sides of the shovel body 410.
[0035] Furthermore, it also includes a pressure strip 460 that clamps the absorbent strip 450 with the squeegee body 410. Specifically, the pressure strip 460 is an injection-molded part with three sections of pressure strip 460 on each side, and the joints of the pressure strips 460 have beveled edges. Meanwhile, the absorbent strip 450 is made of rubber. During installation, the middle pressure strip 460 presses against the beveled edges of the two side pressure strips 460. Screws pass through the holes in the pressure strip 460, the absorbent strip 450, and the squeegee body 410 to the other end and are locked with nuts. Thus, the setting of the pressure strip 460 eliminates the need for the traditional method of using a strip-shaped metal edge to press the absorbent strip 450, saving production costs and enhancing product reliability and sealing. Also, the swing arm 420 set on the rotating shaft 510 that passes through the skirt 110 allows the entire squeegee mechanism 400 to maintain a stable structure on the chassis 100, providing feasible conditions for subsequent wastewater recycling.
[0036] The following is a detailed description of the wastewater recycling exhaust system 2 and float system 1. Please refer to [link / reference]. Figure 6 The float system 1 of this application is coaxially connected to the exhaust system 2 installed on the chassis 100 and built into the sewage tank 300.
[0037] Specifically, it includes a top cover 11, a T-shaped tube 12, a float ball 13, and a ventilation pipe 14 arranged sequentially from top to bottom. The top cover 11 covers the top of the T-shaped tube 12. The horizontal part 121 of the T-shaped tube 12 and the top cover 11 form an air intake chamber, while the vertical part 122 of the T-shaped tube 12 serves as an air intake pipe. Multiple air intake ports 1211 are provided on the outer periphery of the horizontal part 121, preferably six air intake ports 1211, evenly distributed on the outer periphery of the horizontal part 121.
[0038] Meanwhile, the lower end of the vertical part 122 is fitted over the upper end of the ventilation pipe 14. Specifically, the inner diameter of the lower end of the vertical part 122 is slightly larger than the inner diameter of the upper end of the ventilation pipe 14, so that the T-shaped pipe 12 can be easily fitted over the upper end of the ventilation pipe 14.
[0039] At this point, the vertical section 122 and the ventilation pipe 14 form a cylindrical guide structure. The float 13 is a ring structure that can be fitted into the cylindrical guide structure formed by the connection of the vertical section 122 and the ventilation pipe 14 as described above, and can be guided up and down. When the float 13 moves upward, it can block the air intake 1211.
[0040] The float 13 adopts a ring structure design, which can be directly fitted into the vertical part 122 of the T-shaped tube 12 and the ventilation tube 14, and can be freely guided and moved in the vertical direction. While ensuring the effectiveness of the anti-overflow function, it reduces the size of the system and improves the space utilization rate.
[0041] Please refer to the reference. Figure 4 The ventilation pipe 14 passes through the rubber gasket 141 and the bottom opening of the sewage tank 300 from bottom to top and is fixedly connected to the sewage tank 300. The rubber gasket 141 serves to seal and prevent water and air leakage. Specifically, the lower end of the ventilation pipe 14 has a flange 142 integrally molded with the ventilation pipe 14. The flange 142 fits against the rubber gasket 141 and is fixed to the sewage tank 300 with screws, serving to seal the tank and support the float system.
[0042] Thus, when the wastewater tank 300 is empty, the float 13 naturally falls. There is a distance between the float 13 and the upper horizontal section 121 of the T-shaped pipe 12, allowing air to reach the exhaust system 2 through the circumferential air intake 1211 of the horizontal section 121 and then be discharged. This creates negative pressure inside the wastewater tank 300, allowing the floor scrubber to suck up water normally. When the wastewater in the tank 300 reaches a certain height, the annular float 13 will rise, guiding it upwards and sealing the air intake 1211, preventing wastewater from being sucked into the exhaust system 2, thus providing good protection for the motor.
[0043] Thus, the float system adopts a compact design concept, with all components—including the top cover 11, T-tube 12, float 13, and ventilation duct 14—cleverly integrated within the wastewater tank 300 and coaxially connected to the exhaust system 2 mounted on the chassis 100. This design not only greatly saves space, making the entire system suitable for installation in small equipment with limited space, but also simplifies the overall structure, reducing unnecessary complexity and potential points of failure.
[0044] Please refer to Figure 7 and Figure 8The ventilation system 2 includes a motor base 21 mounted on the chassis 100, a vacuum motor 22, a sealing sleeve 23, and a motor cover 24 sequentially fitted into the motor base 21, and a bushing 241 provided in the middle of the motor cover 24.
[0045] The ventilation system 2 and the float system 1 are coaxially connected via an inverted silicone ring 3. Specifically, the ventilation pipe 14 of the float system 1 is inserted into the inner ring of the inverted silicone ring 3, and the outer ring of the lower part of the inverted silicone ring 3 is in contact with the inner ring of the bushing 241.
[0046] As stated above, this case protects a float system and a floor scrubber using it. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
