[0013] The specific implementation of the present application is further described below in conjunction with the accompanying drawings.

[0014] In the description of the present application, it should be understood that the terms "first", "second", etc. are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0015] like Figures 1 to 3 As shown, the drainage bottle cap involved in the present application includes a bottle cap body 2, an assembly hole is provided at the upper end cover of the bottle cap body 2, a fixed body 1 is installed at the assembly hole, a mounting boss 1-1 is provided on the fixed body 1 along the circumferential direction, the upper end cover of the bottle cap body 2 is overlapped at the mounting boss 1-1, and the fixed body 1 is also threadedly connected with a fixing nut 3, and the bottle cap body 2 can be axially (up and down) limited by the fixing nut 3, so that the bottle cap body 2 can only rotate relative to the fixing body 1 and the fixing nut 3. A drainage tube 4 and a connecting tube 5 are also provided on the fixing body 1, respectively. The connecting tube 5 is used to make the air pressure in the liquid storage barrel the same as the external air pressure when the drainage bottle cap is assembled to the liquid storage barrel; the drainage tube 4 is used to connect an external drainage device to extract the liquid in the liquid storage barrel.

[0016] In order to be able to detect in real time whether the remaining amount of liquid in the liquid storage barrel has reached a set value, a guide cylinder 6 is further provided on the fixed body 1 involved in the present application, and a reed switch 11 is provided at the lower end of the inner cavity of the guide cylinder 6, and a lead 13 of the reed switch 11 is led out through an opening at the top of the guide cylinder 6 for external connection with a related control unit; a float 10 is sleeved on the outer wall of the guide cylinder 6, and a magnet 12 is provided on the inner wall of the float 10. Under the action of the buoyancy of the liquid, the float 10 can descend as the liquid level descends.

A limit plate is provided at the bottom end of the guide cylinder 6 to prevent the float 10 from detaching from the guide cylinder 6. Since the detection is whether the remaining amount of liquid in the liquid storage barrel reaches a set value, a limit plate is also provided on the outer wall of the guide cylinder 6 at a preset distance from the bottom end of the guide cylinder 6. The float 10 is located between the two limit plates. The upper limit plate is recorded as the first limit plate 8, and the lower limit plate is recorded as the second limit plate 9.

Two positioning holes are provided on the positioning plate 7 at intervals, and the drainage tube 4 and the guide cylinder 6 pass through the corresponding positioning holes respectively, so that the drainage tube 4 is at a preset distance from the float 10. Specifically, the positioning plate 7 can be fixed on the first limiting plate 8; or the drainage tube 4 and the guide cylinder 6 can be fixedly connected to the positioning plate 7.

[0018] In the specific use process, the drainage bottle cap is used for an external drainage device. During the cleaning process, the drainage bottle cap can seal the liquid storage barrel to prevent the smell of the cleaning liquid from polluting the working environment; the drainage bottle cap and the liquid storage barrel can be installed and disassembled by rotating the bottle cap body 2, and in this process, the fixed body 1 can be prevented from rotating, and then the drainage tube 4 and the lead 13 can be prevented from rotating, avoiding connection problems caused by rotation, such as the connection problem between the drainage tube 4 and the drainage device, and the connection problem between the lead 13 and the relevant control unit; after the drainage bottle cap and the liquid storage barrel are assembled, the liquid in the liquid storage barrel can be extracted through the external drainage device. The drainage bottle cap involved in the present application is provided with a float type liquid level sensor. When the liquid in the liquid storage barrel is reduced to a certain extent, the float 10 drops to a preset position. At this time, the magnet 12 can trigger the reed switch 11, and then the relevant control unit can receive a signal, and then it can be known that the remaining amount of liquid in the liquid storage barrel has reached the preset value.

[0019] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto.
