Description

Bubble machine with good sealing performance

Technical Field

The utility model relates to a bubbling machine.

Background

The bubble machine comprises a gas tank for storing carbon dioxide and a water cup for storing water. The water cup is screwed and fixed at one end of the bubbling machine, and a gas injection pipe inserted into the water cup is arranged on the bubbling machine.

When the water-saving air-blowing type water cup is used, water is injected into the water cup firstly, then the water-blowing machine is screwed, the button is pressed, the valve of the air tank is opened, carbon dioxide in the air tank passes through the water in the water cup through the air injection pipe, then air pressure in the water cup reaches a certain degree, air injection is stopped, then the water cup is unscrewed, and thus the water in the water cup is filled with the carbon dioxide and becomes bubble water.

The bubbling machine needs to pressurize when introducing carbon dioxide into water, so that the sealing between a water cup and a gas cylinder is a serious one, and if the sealing is poor, the leakage amount of the carbon dioxide is large when the gas is inflated every time, and the inflation times of the gas cylinder can be greatly reduced.

The sealing of the existing bubble machine is realized by forming pressure sealing by a cup opening at the top of a water cup and a sealing ring on the periphery of a gas injection pipe, and the mode has the great defect that the sealing pressure between the sealing ring and the bottle opening is required to be formed, so that the requirements on the manufacturing precision and the assembling precision of a product are high, and the condition of untight sealing or incapability of assembling is easy to occur. In addition, after the sealing ring is used for a period of time, the contact area of the sealing ring and the bottle mouth is easy to deform irreversibly, and the existing sealing structure does not have a compensation mechanism, so that the sealing performance is increasingly poor.

The iron block and the magnetic block are matched to form a second layer of seal outside the cup opening, and the magnetic block and the iron block can attract each other as long as being close to each other, so that the requirement on precision is not high.

In the above technical solution, preferably, the iron block and the magnetic block are circular rings.

The utility model has the advantages that: the iron block and the magnetic block are matched to form a second layer of seal outside the cup opening, and the magnetic block and the iron block can attract each other as long as being close to each other, so that the requirement on precision is not high. And the mutual attraction among the magnets is very large, so that good sealing can be formed without labor.

Detailed Description

Referring to fig. 1-4, the bubble machine comprises a shell 1 and a water cup 2, wherein a gas bottle 3, an air extractor 4 and a pure water kettle 5 are arranged in the shell 1.

The air bottle 3 is connected with one end of a hose 31, the other end of the hose 31 is connected with the top of an inflation tube 6, a sealing ring 61 is arranged on the periphery of the top of the inflation tube 6, an insertion hole 11 is formed in the periphery of the shell 1, which is located on the inflation tube 6, and the water cup 2 is inserted into the insertion hole 11.

The outer ring of the sealing ring 61 is in contact with the inner ring of the cup opening of the water cup 2, the sealing ring 61 is hollow, the inner wall of the sealing ring 61 is connected with the hose 31 through the vent pipe 62, and the inflation pipe 6 is internally provided with a first stop valve 63.

The air extracting device 4 is connected with the air charging pipe 6 through an air extracting pipe 41, the pure water kettle 5 is connected with the air charging pipe 6 through a water pipe 51, a second stop valve 42 is arranged in the air extracting pipe 41, and a third stop valve 52 is arranged in the water pipe 51.

The cup 2 is provided with a circle of bulges 21, and when the cup 21 is inserted into the shell 1, the sealing ring 61 is arranged below the bulges 21. The cup opening outer ring of the water cup 2 is provided with a rubber ring 22, the inner ring of the rubber ring 22 is fixed with the outer ring of the cup opening, an iron block 23 is arranged in the rubber ring 22, the outer ring of the sealing ring 61 is provided with a circle of magnetic blocks 62 matched with the iron block 23, and the iron block 23 and the magnetic blocks 62 are circular rings. When the water cup is inserted into the bubble machine, the iron block and the sealing ring attract each other. The iron block and the magnetic block are matched to form a second layer of seal outside the cup opening, and the magnetic block and the iron block can attract each other as long as being close to each other, so that the requirement on precision is not high.

When the gas cylinder is used, the first stop valve is closed firstly, then the gas cylinder is opened, the gas cylinder inflates gas into the sealing ring firstly, the sealing ring expands after being inflated to form close contact with the inner wall of the cup opening of the water cup, then the first stop valve is opened, gas in the gas cylinder enters the water cup, when the gas pressure in the water cup reaches a set value, the gas cylinder stops supplying gas, then the first stop valve is opened, and the gas in the sealing ring enters the water cup. The sealing ring is hollow, and the sealing ring can be inflated and expanded by high-pressure gas in the inflation bottle, so that even if a certain error exists between the sealing ring and the water cup, the sealing ring can be offset by expansion, the requirement on the precision of equipment is not high, and finally the gas filled into the sealing ring can be filled into the water cup, so that the waste is avoided.

The air extractor is connected with the inflation tube through an air extraction tube, the pure water kettle is connected with the inflation tube through a water tube, a second stop valve is arranged in the air extraction tube, a third stop valve is arranged in the water tube, the air extractor is used for evacuating air in the water cup, the water tube is opened after evacuation, pure water in the pure water kettle enters the water cup through the water tube under the action of atmospheric pressure, the third stop valve is closed after a specified amount of water is introduced into the water cup, then the gas cylinder is opened, carbon dioxide enters the water cup through the inflation tube, and the carbon dioxide rapidly expands due to the fact that the water cup is in a vacuum state when the pure water kettle just begins to enter the water cup, so that the temperature in the water cup can be rapidly reduced due to rapid expansion of the air, and the content.

When not aerifing, bellied internal diameter is greater than the external diameter of sealing washer, therefore the sealing washer can insert bellied below, and after the sealing washer aerifyd, the external diameter of sealing washer will be greater than bellied internal diameter, at this moment, the drinking cup just can't be extracted from the gas tube, when we aerify in the drinking cup, atmospheric pressure in the drinking cup increases, can promote the drinking cup and move down, and the sealing washer will be pushed up to the arch at this moment, prevents that the drinking cup from moving down, also can cross to form more reliable sealed simultaneously.
