Abstract

A carbon dioxide filling nozzle device includes an air inlet pipe, a nozzle and a nozzle head. The air inlet pipe includes a head, a rod, a connecting part and an air inlet passage. The nozzle head includes an internal thread cavity part, a receiving cavity and an air outlet. The internal thread of the internal thread cavity part of the nozzle head is screwed with the external thread of the connecting part. The nozzle head is inserted into the air outlet, the lower end of the body is in contact with the bottom plate of the receiving cavity, and the upper end is in contact with the lower end of the connecting part. Since the nozzle is made of a material with a low friction coefficient and low adhesion or no adhesion to any substance, the formation and accumulation of ice in the process of filling the water of the pressure water bottle with carbon dioxide is effectively suppressed. Due to the use of such a structure, the gas is gradually compressed, the gas flow speed is increased, and the ice can be removed more promptly and quickly when ice is formed, so as to keep the nozzle head air outlet unblocked, and the gas quickly rushes into the water. At the same time, the contact time between the carbon dioxide gas flow and the ice water is also increased, thereby increasing the proportion of carbon dioxide dissolved in water.

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] like Figure 1 As shown, a carbon dioxide inflation nozzle device includes an air intake pipe 1, a nozzle 2 and a nozzle head 3. The air intake pipe 1 includes a head, a rod 11, a connecting portion 12 and an air intake passage 13. The nozzle head 3 includes an internal threaded cavity portion 31, an accommodating cavity 32 and an air outlet 33. The internal thread of the internal threaded cavity portion 31 of the nozzle head 3 is screwed with the external thread of the connecting portion 12, and the nozzle 2 is arranged in the accommodating cavity 32.

[0036] The nozzle 2 comprises a body 21, a nozzle head 22 and an air outlet cavity, wherein the air outlet cavity is provided with an inverted frustum-shaped cavity portion 231, a cylindrical cavity portion 232, an inverted frustum-shaped compression portion 233 and a cylindrical air outlet hole portion 234 in sequence from the air inlet end to the air outlet end;

[0037] The nozzle head 22 is inserted into the air outlet 33 , the lower end of the body 21 is in contact with the bottom plate of the accommodating cavity 32 , and the upper end is in contact with the lower end of the connecting portion 12 .

[0038] The inner and outer surfaces of the air outlet cavity of the nozzle 2 are lined with a material layer having a low friction coefficient and having low adhesion or no adhesion to any substance.

[0039] Or the nozzle 2 is made of a material with a low friction coefficient and low adhesion or no adhesion to any substance.

[0040] The air inlet pipe 1, the air nozzle head 3 and the nozzle 2 can be made separately or integrally;

[0041] Or the air inlet pipe 1 and the nozzle 2 can be made separately or in one piece;

[0042] Or the nozzle head 3 and the nozzle 2 can be made separately or integrally;

[0043] The inverted frustum-shaped cavity portion 231 of the nozzle 2 is in the shape of an inverted frustum, and the inverted frustum-shaped compression portion 233 is in the shape of an inverted frustum;

[0044] The cylindrical air outlet portion 234 of the nozzle 2 is in a straight or curved cylindrical or polygonal cylindrical shape.

[0045] For making carbonated beverages, the use temperature of the carbon dioxide cylinder loaded with carbon dioxide is generally higher than 15°C (room temperature). When carbon dioxide is injected into ice water below 6°C to make carbonated water, ice 4 will be formed or partially formed at the cylindrical air outlet portion 234 of the nozzle 2 and its outer edge 235. Any formed ice 4 can block or partially block the cylindrical air outlet portion 234 of the nozzle 2, blocking or reducing the carbon dioxide gas flow injected into the water, thereby reducing the proportion of carbon dioxide dissolved in water.

[0046] The nozzle 2 made of a material with a low friction coefficient and low adhesion or non-adhesion to any material can reduce the formation and accumulation of ice 4 during the inflation process. The formation and accumulation of ice 4 on the cylindrical air outlet portion 234 and the outer edge 235 of the nozzle 2 can be avoided, ensuring the smooth flow of the cylindrical air outlet portion 234, thereby increasing the proportion of carbon dioxide dissolved in water. Materials with a low friction coefficient and low adhesion or non-adhesion to any material, such as tetrafluoroethylene, perfluoroethylene propylene copolymer, perfluoropropyl perfluorovinyl ether and Polytetrafluoroethylene Copolymers, etc.

[0047] The cone angle of the inverted truncated cone compression portion 233 is α, i.e., the airflow guide angle 236;

[0048] The high-speed jet of carbon dioxide gas flow 5 forms an angle with the outer edge 235 of the cylindrical air outlet pipe portion 234, which has a punching effect, so that the carbon dioxide gas flow punches the cylindrical air outlet hole portion 234 and the outer edge 235. When ice 4 is formed, any accumulated ice 4 can be quickly and promptly removed, ensuring the smooth flow of the cylindrical air outlet hole portion 234, thereby increasing the proportion of carbon dioxide dissolved in water.

[0049] The cross-sectional area of ​​the cylindrical air outlet portion 234 is between 0.071 square millimeters and 0.785 square millimeters.

[0050] After the carbon dioxide 5 is ejected from the nozzle 2 of the carbon dioxide gas nozzle device, the contact time with the ice water 801 in the pressure water bottle 8 is proportional to the ratio of carbon dioxide dissolved in water, such as Figure 3 As shown. The contact time of carbon dioxide 5 with ice water is 0.196 square millimeters at the smallest cross-sectional area of ​​the cylindrical air outlet portion 234, which presents an arched trend towards both ends. It should be understood that the proportion of carbon dioxide 5 dissolved in water is 0.196 square millimeters at the smallest cross-sectional area of ​​the cylindrical air outlet portion 234, which presents an arched trend towards both ends, and the optimal cross-sectional area at the smallest point of the cylindrical air outlet portion 234 is between 0.071 square millimeters and 0.785 square millimeters. It should be understood that when the cross-sectional area at the smallest point of the cylindrical air outlet portion 234 is between 0.071 square millimeters and 0.785 square millimeters, the proportion of carbon dioxide dissolved in water is the highest.

[0051] As a further improvement of the present invention: it also includes a vortex guide 6, such as Figure 1 , Figure 4 , Figure 5 As shown, the vortex guide member 6 includes an air guide cavity portion 61 with an upper opening and an inverted frustum-shaped air guide head portion 62. The wall plate of the air guide cavity portion 61 is provided with evenly distributed axial air guide grooves 611, and the bottom plate is provided with axial guide holes 612 communicating with the axial air guide grooves 611; the inverted frustum-shaped air guide head portion 62 is provided with a spiral air guide groove 621; the spiral air guide groove 621 is communicated with the axial guide hole 612;

[0052] The inverted truncated cone-shaped gas guide head 62 is inserted into the inverted truncated cone-shaped cavity 231, the bottom plate of the gas guide cavity 61 is in contact with the upper end of the nozzle 2, and the top of the gas guide cavity 61 is in contact with the end of the connecting portion 12;

[0053] The air inlet pipe 1, the air nozzle head 3 and the nozzle 2 can be made separately or integrally;

[0054] Or the air inlet pipe 1 and the nozzle 2 can be made separately or in one piece;

[0055] Or the nozzle head 3 and the nozzle 2 can be made separately or integrally;

[0056] Or the air inlet pipe 1, the vortex guide 6 and the nozzle 2 may be made separately or integrally;

[0057] Or the air inlet pipe 1, the nozzle head 3, the vortex guide 6 and the nozzle 2 can be made in separate parts or in one piece;

[0058] Or the nozzle head 3, vortex guide 6 and nozzle 2 can be made in separate parts or in one piece;

[0059] The nozzle 2 and the vortex guide 6 can be manufactured separately or integrally.

[0060] The high-speed injection of the vortex carbon dioxide gas flow will further enhance the carbon dioxide gas flow to peel off the cylindrical gas outlet portion 234 and the outer edge 235 of the nozzle. The carbon dioxide gas flow is vortexed by the spiral air guide groove 621, further enhancing the carbon dioxide gas flow to peel off the cylindrical gas outlet portion 234 and the outer edge 235, and more effectively remove the accumulated ice 4 quickly and timely when forming ice 4, ensuring the smooth flow of the cylindrical gas outlet portion 234. At the same time, the contact time between the vortex carbon dioxide gas flow and the ice water is also increased, thereby increasing the proportion of carbon dioxide dissolved in water.
