Therefore, in some embodiments, the new foaming device includes a nozzle, an infusion unit, a medicine supply unit, and a gas supply unit. The infusion unit includes a mixed liquid delivery pipe, a foam delivery pipe, a bubble tube and a bubble net plate. The bubbling pipe connects the mixed liquid conveying pipe and the foam conveying pipe and has a cross-sectional area larger than that of the mixed liquid conveying pipe and the foam conveying pipe. One end of the mixed liquid conveying pipe is used to connect a water source, and one end of the foam conveying pipe is connected to the Nozzle, the foaming net plate has a plurality of holes and is arranged on a cross section of the foaming tube. The medicine supply unit is connected to the mixed liquid delivery pipe for supplying medicine to the mixed liquid delivery pipe to be mixed with water. The gas supply unit is connected to the mixed liquid conveying pipe for supplying gas into the mixed liquid conveying pipe.

In some embodiments, the cross-sectional area of the bubbling tube is at least 7 times the cross-sectional area of the mixed liquid delivery tube and the foam delivery tube.

In some embodiments, the hole diameter of the foamed mesh plate is 1 mm.

In some embodiments, the bubbling tube has a main section and a connecting end with a diameter tapering from the main section to the direction of the foam delivery pipe, and the bubbling net plate is close to the main section and the connecting end. And the connecting end forms an expansion space for generating foam.

In some embodiments, the medicine supply unit is located upstream of the gas supply unit, the infusion unit further includes a one-way valve provided in the mixed liquid delivery pipe, and the one-way valve is located in the mixed liquid delivery pipe Between the connection with the medicine supply unit and the connection with the gas supply unit.

In some embodiments, the length of the bubble tube is between 5 and 7 cm.

In some embodiments, the mixed solution delivery tube has a necked section with a smaller cross-sectional area, and the medicine supply unit is connected to the necked section.

The new type has the following effects: better foaming effect can be produced by the simple structure of the foaming tube and the foaming net plate, not only can save the manufacturing cost, but also can save the volume occupied by the equipment.

1 and FIG. 2, the embodiment of the foaming device of the present invention includes a nozzle 1, an infusion unit 2, a medicine supply unit 3, and a gas supply unit 4.

The infusion unit 2 includes a mixed liquid conveying pipe 21, a foam conveying pipe 22, a bubble pipe 23, and a bubble net plate 24. The bubble pipe 23 connects the mixed liquid conveying pipe 21 and the foam conveying pipe 22 and has a cross-sectional area. Larger than the mixed liquid conveying pipe 21 and the foam conveying pipe 22, one end of the mixed liquid conveying pipe 21 is used to connect a water source W, one end of the foam conveying pipe 22 is connected to the nozzle 1, and the foaming mesh plate 24 has a plurality of holes 241 is also arranged on a cross section of the bubbling tube 23. In this embodiment, the cross-sectional area of the bubbling tube 23 is at least 7 times the cross-sectional area of the mixed liquid conveying pipe 21 and the foam conveying pipe 22. The bubbling pipe 23 has a main section 231 and a main section 231. 231 is a connecting end 232 whose diameter is tapered toward the foam delivery pipe 22. The foaming mesh plate 24 is close to the junction of the main body section 231 and the connecting end 232, and the connecting end 232 forms a foam generating The expansion space 233. Specifically, in this embodiment, the mixed liquid delivery pipe 21 and the foam delivery pipe 22 are divided into two pipes, and the bubble pipe 23 is a 1-inch pipe. The length of the bubble tube 23 is between 5 and 7 cm, which can save materials and reduce the volume. The hole 241 of the foamed mesh plate 24 has a hole diameter of 1 mm.

The medicine supply unit 3 is connected to the mixed liquid delivery pipe 21 for supplying medicine into the mixed liquid delivery pipe 21 to be mixed with water. In this embodiment, the mixed solution delivery pipe 21 has a necked section 211 with a smaller cross-sectional area, and the medicine supply unit 3 is connected to the necked section 211, so that the medicine can be mixed into the water more uniformly. The gas supply unit 4 is connected to the mixed liquid conveying pipe 21 for supplying gas into the mixed liquid conveying pipe 21. In this embodiment, the medicine supply unit 3 is located upstream of the gas supply unit 4. The infusion unit 2 further includes a check valve 25 provided in the mixed liquid delivery pipe 21, and the check valve 25 is located Between the connection point A of the mixed liquid delivery pipe 21 and the medicine supply unit 3 and the connection point B of the gas supply unit 4. Specifically, the medicament supply unit 3 includes a medicament barrel (not shown) to store medicaments, and a pump (not shown) that controls the flow rate to supply medicaments to the mixed liquid delivery pipe 21 to form a mixture with water. liquid. The gas supply unit 4 includes an air pump (not shown) to pump air into the mixed liquid. The one-way valve 25 is used to prevent the mixture of medicine and water from flowing back into the medicine barrel.

When this embodiment is in operation, the water pressure entering the mixed liquid delivery pipe 21 is about 200 psi, and the air pressure of the air pump is about 80 psi. When the mixture of medicine and water is mixed with air and then flows into the bubbling pipe 23, due to the mixing The liquid flows from the mixed liquid delivery pipe 21 with a smaller diameter into the bubble tube 23 with a larger diameter, which will slow down the flow rate. When the mixed liquid enters the expansion space 233 through the bubble mesh plate 24, it can penetrate Press to produce more foam, and make the foam more dense and fine.

In summary, the simple structure of the bubble tube 23 and the bubble mesh plate 24 can produce a better bubble effect, which not only saves manufacturing costs, but also saves the volume of equipment occupied.

However, the above are only examples of the present model. When the scope of implementation of the present model cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present model and the contents of the patent specification still belong to This new patent covers the scope.
