[0015] Embodiment 1

[0016] See also Figure 1-3 A combined rubber plug includes a main body 1, a cavity is formed in the main body 1, a tube sleeve 8 is fixedly connected to the main body 1, a bottom plate 6 is fixedly connected to the tube sleeve 8, a plurality of through holes are formed in the tube sleeve 8, an air bag 5 is fixedly connected to the edge of the through hole, a piston rod 4 is airtightly and slidably connected in the main body 1, a handle 3 is fixedly connected to the piston rod 4, the air bag 5 is communicated with the cavity, and there is damping between the piston rod 4 and the main body 1.

[0017] A clearance hole is provided in the bottom plate 6 , and the airbag 2 7 is fixedly connected in the clearance hole. The airbag 2 7 , the airbag 1 5 and the cavity are connected, and the elastic coefficient of the airbag 2 7 is greater than the elastic coefficient of the airbag 1 5 .

[0018] Before use, the main body 1 is inserted into the bottle mouth and the airbag 5 is located below the bottle mouth. Then the user pushes the handle 3 to let the handle 3 drive the piston rod 4 to move downward in the main body 1, pushing the gas in the cavity into the airbag 5, and the airbag 5 is inflated. The inflated airbag 5 can be stuck around the bottle mouth. Even bottles of different calibers can use this design, and the ductility of the airbag 5 is used to fill the bottle mouth to achieve sealing ability. In order to improve the tightness of the fit between multiple airbags 5 as much as possible, it is necessary to move the piston rod 4 downward as much as possible. The moving paths of the piston rod 4 corresponding to bottles of different calibers are different. In order to improve the fault tolerance of users when using this design, the design of airbag 2 7 can share the air pressure to a certain extent, reduce the bursting of airbag 1 5 due to improper operation of the user, that is, when the air pressure of airbag 1 5 reaches a certain value, the airflow will enter airbag 2 7, expand airbag 2 7, and will not continue to expand airbag 1 5 at the same rate.

[0019] A slide plate 10 is slidably connected to the bottom plate 6, a brush 11 is fixedly connected to one end of the slide plate 10, and a plurality of abutment plates 12 are fixedly connected to the end surface of the slide plate 10, and the abutment plates 12 are located on the moving path of the expanded airbag 5. During the expansion of the airbag 5, the slide plate 10 and the brush 11 can be extended through the abutment contact between the side wall of the airbag 5 and the abutment plates 12, so that the brush 11 can contact the inner wall of the bottle. At this time, the main body 1 is rotated to drive the main body 1 to wipe the powder on the contacted surface, thereby achieving a certain cleaning purpose.

[0020] Embodiment 2

[0021] See also Figure 1-3 On the basis of the above embodiment, a one-way valve 9 is installed in the cavity of the main body 1, and the one-way valve 9 divides the cavity into an upper chamber and a lower chamber. The lower chamber is arranged close to the airbag 5, and a negative pressure mechanism is arranged on the side wall of the upper chamber.

[0022] The negative pressure mechanism includes a side opening pipe 14, a sealing plate 15 and a sealing cover 2. A plurality of connecting pipes 17 are opened on the main body 1. Each connecting pipe 17 is elastically and slidably connected to a sealing plate 15. The sealing plate 15 is located on the inner side of the main body 1. The outer side of the main body 1 is sleeved with a sealing cover 2. The sealing cover 2 is connected to the side opening pipe 14. The side opening pipe 14 and the sealing cover 2 are both made of rubber. A magnetic valve 13 is elastically and slidably connected to the main body 1.

[0023] When in use, due to the presence of the one-way valve 9, this design is specifically divided into two operating steps. The first operating step is to extend the bottom plate 6 into the bottle. At this time, you can choose to clamp the airbag 5 at the bottle mouth or the bottleneck. The above two places can allow the airbag 5 to achieve the purpose of sealing and plugging. The second operating step is when the bottle mouth of the target bottle is provided with a thread, clamp the cover 2 to the edge of the bottle so that the cover 2 can surround the edge. Because the rubber cover 2 has a certain ductility, bottles of different calibers can be wrapped with the same cover 2 within a certain range. Then, the position of the cover 2 is adjusted so that the cover 2 is inserted into a suitable connecting tube 17. At this time, the side opening pipe 14 on the cover 2 will lift the sealing plate 15 corresponding to the connecting tube 17, so that the cover 2 is connected to the upper chamber. Then, the user pulls the piston rod 4 upwards. Due to the presence of the one-way valve 9, the gas in the lower chamber will not flow, and the inner wall of the cover 2 The sealing plate 15 on the connecting tube 17 on both sides of the sealing cap 2 will not move due to the limitation of elastic force. When the main body 1 needs to be removed from the bottle, a magnet with the same magnetic property as the magnetic valve 13 is used to approach the magnetic valve 13 from the outside of the bottle. Under the action of magnetic repulsion, the magnetic valve 13 is pushed to shrink into the main body 1. At this time, the gas in the lower chamber leaks out, the airbag 15 is restored, and the piston rod 4 is pushed downward again, so that the pressure between the sealing cap 2 and the bottle mouth is restored, so that the entire rubber stopper can be taken out. Compared with the prior art, the present design utilizes double sealing effect, which can greatly improve the sealing ability of the bottle.
