[0027] The inner wall of the fixed rod 5 is provided with a discharging device 7, which comprises a sliding block 71, a through hole 72, a connecting hole 73 and a cavity 74. The sliding block 71 is slidingly connected to the inner wall of the fixed rod 5. The connecting hole 73 is arranged in the interior of the sliding block 71. The connecting hole 73 is arranged on the surface of the fixed rod 5. The cavity 74 is arranged in the inner wall of the top of the fixed rod 5. The through hole 72 is arranged in the interior of the sliding block 71. When the pressing is finished, the spring will drive the sliding rod 2 to move upward and reset through the ball 13. At this time, the discharge hole 14 moves into the cavity 74 at the top of the fixed rod 5. The spring compressed above the pressing plate 16 will drive the pressing plate 16 to move downward. The pressing plate 16 will push the remaining emulsion in the sliding rod 2 out, so that the excess emulsion enters the cavity 74. The pressing plate 16 moves downward while applying pressure to the emulsion. At this time, the pressure in the cavity 74 increases. The pressure will drive the sliding block 71 to move, so that the through hole 72 in the sliding block 71 is in communication with the connecting hole 73 in the fixed rod 5, allowing the excess emulsion in the cavity 74 to flow out into the bottle, preventing waste. The cavity 74 and the discharge hole 14 are in communication with each other. The sliding block 71 and the fixed rod 5 are provided with a spring.

[0028] The working principle is that the device is installed on the bottle. When in use, the pressing block 3 is pressed down. The pressing block 3 will drive the sliding rod 2 to move downward. The discharge hole 14 on the sliding rod 2 will move to the inner wall of the fixed rod 5. At this time, the fixed rod 5 is in communication with the sliding rod 2. At the same time, the pressing block 3 will contact the pressing switch 11. When the pressing switch 11 is pressed, it will send an electrical signal to the booster pump 10. At this time, the booster pump 10 starts and delivers gas into the bottle, thereby increasing the pressure inside the bottle. After the pressure in the bottle increases, the emulsion will be squeezed into the straw 6 and flow to the pressing block 3 through the sliding rod 2 and the fixed rod 5 in communication. At the same time, it will lift the pressing plate 16 and compress the spring on the top of the pressing plate 16. When the pressing plate 16 moves to the upper side of the discharge pipe 4, the emulsion will be squeezed out through the discharge pipe 4. Thus, after the pressing block 3 is pressed, the pressure in the bottle can be automatically increased, thereby eliminating the need for reciprocating pressing, saving more labor and being more convenient.

[0029] When the pressing is finished, the spring will drive the sliding rod 2 to move upward and reset through the ball 13. At this time, the discharge hole 14 moves into the cavity 74 at the top of the fixed rod 5. The spring compressed above the pressing plate 16 will drive the pressing plate 16 to move downward. The pressing plate 16 will push the remaining emulsion in the sliding rod 2 out, so that the excess emulsion enters the cavity 74. The pressing plate 16 moves downward while applying pressure to the emulsion. At this time, the pressure in the cavity 74 increases. The pressure will drive the sliding block 71 to move, so that the through hole 72 in the sliding block 71 is in communication with the connecting hole 73 in the fixed rod 5, allowing the excess emulsion in the cavity 74 to flow out into the bottle, preventing waste.
