[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0022] Embodiment 1:

[0023] like Figure 1-4 As shown, a vacuum flushing device of the utility model includes a filter barrel 20, a cover plate 4 is provided on the top of the filter barrel 20, a motor 5 is fixedly installed on the upper surface of the cover plate 4, the output shaft of the motor 5 passes through the cover plate 4 and is fixedly connected to a connecting shaft 14, a filter element 19 is sleeved on the outer side of the connecting shaft 14, and a rectangular column 18 is fixedly connected to the lower end of the connecting shaft 14, a cleaning brush 16 is sleeved on the outer side of the rectangular column 18, a tension spring 22 is fixedly installed on the bottom of the cleaning brush 16, and one end of the tension spring 22 is fixedly connected to a positioning piece 21 that passes through the U-shaped block 17 and the rectangular column 18.

[0024] like Figure 1As shown, two clips 7 are fixedly installed between the cover plate 4 and the filter barrel 20, a short tube 3 is fixedly connected to the outside of the filter barrel 20, a water storage pipe 12 is screwed to the bottom of the filter barrel 20, a fixing plate 11 is sleeved on the outside of the water storage pipe 12, four fixing holes 6 are evenly opened on the upper surface of the fixing plate 11, and a vacuum pump 1 is fixedly installed on the upper surface of the fixing plate 11, and a connecting pipe 2 is connected between the vacuum pump 1 and the short tube 3.

[0025] During implementation, a cleaning brush 16 is provided at the bottom of the filter element 19. By starting the motor 5, the connecting shaft 14 connected to its output shaft is driven to rotate, so that the rectangular column 18 connected to it is controlled to drive the cleaning brush 16 to rotate, thereby facilitating the removal of dirt at the bottom of the filter element 19. Moreover, by pulling the positioning member 21, the tension spring 22 is stretched, so that one end of the positioning member 21 is separated from the interior of the rectangular column 18, thereby facilitating the removal and replacement of the cleaning brush 16. This solves the technical problem that for the vacuum flushing device, the structure adopted by the device is to prevent particulate matter from entering the interior of the vacuum pump 1, and a filtering structure is usually provided inside. However, long-term use may cause the filtering structure to be blocked, thereby affecting the air extraction effect.

[0026] Embodiment 2:

[0027] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: the outer side of the water storage pipe 12 is fixedly connected with the air intake pipe 9, the pipe of the air intake pipe 9 is provided with a solenoid valve 10, and one end of the air intake pipe 9 is screwed with a cover shell 25, the inner side of the cover shell 25 is fixedly installed with a filter screen 8, the lower surface of the cover plate 4 is symmetrically fixedly installed with a limit plate 13, the bottom of each limit plate 13 is in contact with the filter element 19, the inner side of the filter barrel 20 is symmetrically provided with a slide groove 23, the outer side of the filter element 19 is symmetrically fixedly installed with a slider 24 slidably connected to the slide groove 23, the bottom of the filter element 19 is provided with a support plate 15 connected to the filter barrel 20, and the support plate 15 is an annular structure.

[0028] During implementation, the filter element 19 and the filter barrel 20 are movably connected by a slider 24 and a slide groove 23, and the vertical position of the filter element 19 is limited by a support plate 15 and a limit plate 13. By opening the cover plate 4, the filter element 19 can be easily disassembled for replacement or cleaning.

[0029] In the present technical solution, a liquid level sensor is provided at a certain height inside the water storage pipe 12. When in use, the vacuum pump 1 is started to evacuate the air inside the water storage pipe 12, so that the water storage pipe 12 reaches a negative pressure state, thereby pumping the water in the regulating reservoir into the water storage pipe 12 through the water storage pipe 12. When the water reaches a certain height, the liquid level sensor controls the solenoid valve 10 to open, and the vacuum pump 1 is closed at the same time. The air enters the inside of the water storage pipe 12 after being filtered by the filter screen 8, and contacts the negative pressure state. Under the action of gravity, the water falls and impacts the regulating reservoir to clean the regulating reservoir. When the bottom of the filter element 19 needs to be cleaned, the motor 5 is started to drive the connecting shaft 14 connected to its output shaft to rotate, and the rectangular column 18 connected to it drives the cleaning brush 16 to rotate to remove the dirt at the bottom of the filter element 19. When it is necessary to remove the cleaning brush 16 and the filter element 19, first open the buckle 7, separate the cover plate 4 from the filter barrel 20, and make the filter element 19 detach from the interior of the filter barrel 20, then pull the positioning piece 21 to stretch the tension spring 22, so that one end of the positioning piece 21 detaches from the interior of the rectangular column 18, and finally remove the cleaning brush 16 from the outside of the rectangular column 18, and remove the filter element 19 from the outside of the connecting shaft 14 and the rectangular column 18.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
