The bottle mouth is provided with a spraying device 2 used for atomizing the liquid into aerial fog to be sprayed.

The piston 3 divides the cavity in the bottle body 1 into a liquid chamber 10 at the upper part and a gas chamber 11 at the lower part, i.e. the liquid chamber 10 is above the piston 3 and the gas chamber 11 is below. The compressed gas container 4 is inserted from the bottom of the flask body 1 and is hermetically connected to the inner surface of the flask body 1. The liquid chamber 10 is filled with liquid and the compressed gas container 4 is filled with compressed gas. The compressed gas container 4 has a container mouth at the top center, and in an initial state, i.e., when not loaded in the bottle body 1, the container mouth is closed by the lid body 40, and the bottom of the compressed gas container 4 is closed by the bottom lid 42. The lower part of the container mouth is provided with a circular arc-shaped container shoulder 41 which is matched with the shape of the piston 3 and leads the compressed gas to be converged at the container mouth. The bottom of the piston 3 is provided with a convex part 30 which can open the cover body 40 to release compressed gas, the convex part 30 is a circular convex part 30, the cover body 40 is a sealing plug, the sealing plug is tightly plugged through a limiting structure of a container opening in an initial state, and when the compressed gas container 4 is sleeved in the bottle body 1, the convex part 30 acts on the cover body 40 to push the cover body 40 downwards. When the cover 40 is in an open state, the compressed gas container 4 is communicated with the gas cavity 11 to form a closed structure.

The upper part of the piston 3 has an arc part which is attached to the shoulder 12 of the bottle body, and the center of the arc part is depressed downward to form a groove 33 which is matched with the bottom of the spraying device 2, and when the piston 3 is positioned at the top of the bottle body 1, the bottom of the spraying device 2 is placed in the groove 33.

As shown in fig. 2, the piston 3 is made of rubber, a plurality of beads 32 attached to the inner wall of the bottle body 1 are provided on the circumferential portion of the piston 3, the beads 32 are stacked in the axial direction, the maximum diameter of each bead 32 is equal, and the top end of the bead 32 positioned at the lower stage is positioned inside the upper bead 32. Each folded edge 32 is attached to the inner side wall of the bottle body 1 to form a multi-layer closed structure, so as to enhance the sealing effect and prevent the compressed gas from entering the liquid chamber 10.

As shown in fig. 3, a plurality of ribs 31 are provided at intervals in the circumferential direction inside the arc portion of the piston 3. The mechanical property of the arc-shaped piston 3 can be enhanced, and the deformation of the arc-shaped piston can be prevented.

As shown in fig. 1, the spray device 2 is an aerosol spray head including a pressing head 21 connected to a head case 20 to be pressed, a resilient mechanism 22 and a stopper mechanism for resiliently urging the pressing head 21 to an initial position, and an extraction tube 23 provided inside the pressing head 21 for extracting liquid, and a nozzle 24 is provided on one side of the extraction tube 23. In the initial state, the pressing head 21 is restricted by the stopper mechanism by the resilient mechanism 22 to seal the space between the nozzle 24 and the bottle body 1, and when in use, the pressing head 21 is pressed to draw out the liquid from the liquid drawing tube 23, and the liquid mist is ejected through the nozzle 24.

The working principle of the embodiment is as follows:

the piston 3 presses the pressing head 21 of the spraying device 2 upward to press the liquid upward by the compressed gas, and the liquid forms a gas mist through the spraying device 2 and is sprayed.

Example two

This embodiment is substantially the same as the first embodiment, except that:

referring to fig. 1 and 4, the protrusion 30 provided at the bottom of the piston 3 has a spike 300, the cap 40 is a plastic cap, the sealing plug is plugged by the limiting structure of the container mouth in the initial state, and when the compressed gas container 4 is mounted in the bottle body 1, the protrusion 30 acts on the cap 40 to puncture the cap 40. When the cover 40 is in an open state, the compressed gas container 4 is communicated with the gas cavity 11 to form a closed structure.
