Technical Field

The invention relates to the technical field of a bubble water machine, in particular to an anti-condensation blocking gas injection pipe for the bubble water machine.

Background

Carbon dioxide dissolves to some extent in water and is called "bubble water" because of the presence of carbon dioxide gas. The bubble water has a fresh taste and plays a variety of roles of suppressing appetite, eliminating constipation, blocking absorption of carbohydrate fat, neutralizing acidity in the body, and the like, and thus is enjoyed by more and more users. A bubble water machine, which is a machine for manufacturing bubble water as the name implies, belongs to the field of small household appliances.

The operating principle of the bubble water machine is as follows: the valve of the carbon dioxide gas cylinder is opened through the air inlet pressure rod and the air inlet thimble, compressed air in the carbon dioxide gas cylinder is conveyed into the air injection pipe through the air guide pipe and is instantaneously released into purified water or other beverages in the container bottle from the lower end mouth part of the air injection pipe, and therefore bubble water is prepared. It follows that the gas injection tube in direct contact with the solution also plays a critical role throughout the operation of the bubble water.

At present, the gas injection pipe on the market is generally formed by integrally injection molding plastic parts, and has some defects due to the reason of manufacturing process: firstly, the pore diameter of the air outlet of the air injection pipe is often inconsistent in size, so that the air pressure in the water bottle is high after the pressure of the machine is released, liquid is easy to spray out, and meanwhile, the risk of explosion of the water bottle is caused when the pressure in the water bottle is increased; secondly, there are two types of gas outlet structures of gas injection pipes (refer to fig. 1 and 2, in the drawings, 1a is a conveying channel, 1b is a gas injection pipe, 1c is a gas outlet, and 1d is an airflow shape): one is that the outlet end is provided with a concave counter bore larger than the air outlet hole (figure 1), and the other is that the air outlet hole is a taper hole (figure 2), and the two structures can cause the icing of the air outlet hole position to cause the air outlet blockage to be incapable of discharging air. The reason is that the gas temperature of the carbon dioxide gas discharged through the gas outlet hole is about minus 20 ℃, so that when the high-pressure low-temperature gas of the carbon dioxide gas is discharged through the gas outlet hole, the shape of the gas flow is conical, the diameter of the end of the gas outlet hole is the hole of the gas outlet hole, the diameter of the gas flow is about 5 mm far away from the hole by about 3 mm, the gas outlet is structured as described above, the gas cannot be discharged smoothly, the temperature of the exhaust nozzle is reduced, the temperature cannot be quickly desorbed by water and absorbed to form ice, gas backflow is easily formed in the blocked gas outlet, and the carbon dioxide compressed gas can absorb a large amount of heat around the gas outlet when being released instantly, so that the gas injection pipe is easily frozen in a low-temperature environment (generally an environment lower than 10 ℃) to cause the blockage of the gas injection pipe. When a user manufactures bubble water, the refrigerated water is often used as a raw material to be processed, and the bubble water machine with the gas injection pipe structure is used without worry, so that the use experience is influenced.
