[0019] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , 2 As shown, a floor scrubber for preventing sewage from flowing out includes a floor scrubber main frame 1, an electric brush disc 3 is installed on the lower surface of the front end of the floor scrubber main frame 1, a water storage tank 2 is installed on the front surface of the floor scrubber main frame 1, and the water storage tank 2 is connected to the electric brush disc 3, a squeegee 7 is installed on the lower surface of the rear end of the floor scrubber main frame 1, a water absorption strip 5 is installed inside the squeegee 7, a sewage tank 8 is fixedly installed on the rear surface of the floor scrubber main frame 1, a vacuum pump 11 is installed on the sewage tank 8, an anti-outflow component 6 is arranged on the squeegee 7, a sewage pipe 12 is installed on the squeegee 7 through the anti-outflow component 6, and the top of the sewage pipe 12 is arranged inside the sewage tank 8.

[0021] like Figure 1 As shown, an electric roller 4 is installed on the lower end surface of the main frame 1 of the floor scrubber to facilitate the movement of the device.

[0022] like Figure 1 As shown, support rods 9 are fixedly installed on both sides of the rear end surface of the main frame 1 of the floor scrubber, and a pull rod 10 is fixedly installed between the inner walls of the two support rods 9 to facilitate the staff to push the device.

[0023] like Figure 2 , 3As shown in Figures 4 and 5, the anti-outflow component 6 includes a connecting pipe 601, which is installed on the upper surface of the squeegee 7, and the sewage pipe 12 is installed on the connecting pipe 601. A fixing plate 602 is fixedly installed in the middle of the connecting pipe 601, and a mounting rod 603 is fixedly installed between the inner walls on both sides of the connecting pipe 601. A guide column 604 is slidably installed through the middle of the mounting rod 603, and a top plate 606 is fixedly installed on the upper end of the guide column 604. A reset spring 605 is fixedly installed on the lower surface of the top plate 606, and the lower end of the reset spring 605 is arranged on the upper surface of the mounting rod 603. A sealing groove 609 is opened on the inner surface of the fixing plate 602, and a mounting plate 607 is fixedly installed on the lower end of the guide column 604. A sealing ring 608 is fixedly installed on the lower surface of the mounting plate 607. The sealing ring 608 is arranged inside the sealing groove 609, and works through the water pump 11 to draw the sewage tank 8 into a vacuum, thereby generating suction inside the sewage pipe 12 to absorb the sewage on the ground. After the absorption is completed, when the suction disappears, the elasticity of the reset spring 604 will reset the mounting plate 607, and the mounting plate 607 will be attached to the connection between the fixed plate 602 and the connecting pipe 601 to block the residual water in the sewage pipe 12 from flowing out and affecting the cleaning efficiency. In addition, due to the resilience of the reset spring 605, the upward distance of the mounting plate 607 will be limited, and the upper end of the fixed plate 602 will not be blocked. The sealing ring 608 is arranged inside the sealing groove 609, which can make the fixed plate 602 and the mounting plate 607 fit more closely.

[0024] The working principle of this kind of floor scrubber that prevents sewage from flowing out:

[0025] When in use, when the device needs to be used for floor washing, cleaning liquid is stored in the water tank 2 and the cleaning liquid flows to the electric brush plate 3. At this time, the electric brush plate 3 is rotated to clean the floor. At this time, the device is moved forward as a whole, and the squeegee 7 scrapes and collects the sewage on the floor. At this time, the water pump 11 works to draw the sewage tank 8 into a vacuum, so that suction is generated inside the sewage pipe 12 to absorb the sewage on the floor. After the absorption is completed, when the suction disappears, the elasticity of the reset spring 604 will reset the mounting plate 607, and the mounting plate 607 will be attached to the connection between the fixed plate 602 and the connecting pipe 601 for blocking, so as to prevent the residual water in the sewage pipe 12 from flowing out and affecting the cleaning efficiency. Moreover, due to the resilience of the reset spring 605, the upward distance of the mounting plate 607 will be limited, and the upper end of the fixed plate 602 will not be blocked.

[0026] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
