DETAILED DESCRIPTION

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] like Figures 1-5 As shown, a defoaming device for beverage filling includes a mounting plate 1. A bottle neck pressure ring 2 is installed at the bottom of the mounting plate 1, and a silicone sealing ring 3 is provided at the bottom of the bottle neck pressure ring 2. A filling tube 4 is passed through and fixed between the top and bottom of the mounting plate 1. A ventilation exhaust pipe 5 is passed through and installed between the top and bottom of the mounting plate 1. The ventilation exhaust pipe 5 includes an airflow extraction pipe 6 and a first airflow intake pipe 7, which are fixed on the mounting plate 1 and are connected to each other. A second airflow intake pipe 8 is connected to the bottom of the airflow extraction pipe 6. An air filter 9 and a miniature air pump 10 are installed on the top of the mounting plate 1.

An expandable bubble puncturing device 14 is connected to the bottom of the first rotating shaft 13.

[0033] The beverage is fed into the beverage bottle through the filling tube 4. During the filling process, the micro vacuum pump 10 can be controlled to operate, creating negative pressure to draw air from the air extraction tube 6. Under the suction, the air inside the beverage bottle is drawn into the air extraction tube 6 through the second air intake pipe 8. At the same time, outside air enters the first air intake pipe 7 under negative pressure. The air in both the first and second air intake pipes enters the air extraction tube 6. By setting the first air intake pipe 7, the air in the beverage bottle can be extracted while maintaining the pressure in the beverage bottle at a normal level. Furthermore, because the silicone sealing ring 3 presses the bottle opening of the beverage bottle to be filled, no new air enters the bottle. As the air in the beverage bottle is continuously discharged with the rise of the liquid level and the suction of the micro vacuum pump 10, and no new air enters, fewer bubbles are generated at the top of the liquid surface during filling, reducing the time and difficulty required for defoaming.

[0034] After filling is completed, the motor 12 drives the first rotating shaft 13 and the expandable bubble puncturing device 14 to rotate. Under the action of centrifugal force, the centrifugal automatic expansion arm 17 expands, increasing the effective area of ​​the expandable bubble puncturing device 14.

[0039] The piercing rod mechanism comprises a bubble piercing sharp rod 19 installed at the bottom of the mounting seat 15 and the centrifugal automatic expansion cantilever 17, and a lateral sharp point 20 is arranged on the side of the bubble piercing sharp rod 19.

[0040] The bubble piercing sharp rod 19 and the lateral sharp point 20 cooperate to pierce the bubbles on the liquid surface.

[0041] The pipe diameters of the first air flow suction pipeline 7 and the second air flow suction pipeline 8 are smaller than the pipe diameter of the air flow suction pipeline 6.

[0042] The pipe diameters of the first air flow suction pipeline 7 and the second air flow suction pipeline 8 are smaller than the pipe diameter of the air flow suction pipeline 6, so that the air in the first air flow suction pipeline 7 and the second air flow suction pipeline 8 can be evenly sucked out to the air flow suction pipeline 6.

[0043] The bottom of the fixed cantilever 24 is provided with a limiting rod 21.

[0044] The limiting rod 21 is used for limiting the position of the centrifugal automatic unfolding cantilever 17 after reset.
