The disclosure relates to a bubble generating device.
Referring to
However, a length of the jet tube unit 13 is too long. The jet type bubble generating machine occupies a large space. Further, because the cutting webs 14 are disposed in the jet tube unit 13, impurities easily clog up the cutting webs 14 and need to be regularly cleaned.
Therefore, an object of the disclosure is to provide a bubble generating device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, a bubble generating device includes a casing unit, a gas intake unit, and a liquid input unit.
The casing unit includes a first casing end, a second casing end opposite to the first casing end, and a flow passage converging from the first casing end towards the second casing end to allow a fluid to flow in a flowing direction from the first casing end to the second casing end.
The gas intake unit includes a mounting part mounted to and closing the first casing end, a protrusion projecting and tapering from the mounting part into the flow passage, and a gas channel extending through the mounting part and the protrusion. The gas channel communicates with the flow passage for introducing the gas into the flow passage.
The liquid input unit is connected to the casing unit and includes a liquid channel communicating with the flow passage for introducing the liquid into the flow passage.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:
The casing unit 3 includes a first casing end 31, a second casing end 32 opposite to the first casing end 31, and a flow passage 33 converging from the first casing end 31 towards the second casing end 32 to allow a fluid to flow in a flowing direction (d1) from the first casing end 31 to the second casing end 32.
The flow passage 33 has a converging section 35, a constricted uniform width section 36, and a passage central axis 34 passing through the converging section 35 and the constricted uniform width section 36 along the flowing direction β(d1).
The converging section 35 has a substantially frustoconical cross section and tapers from the first casing end 31 toward the second casing end 32. The length (L11) thereof is 3.1 cm. An angle (A1) of 23.7 degrees is formed between a boundary wall of the converging section 35 and the passage central axis 34. The converging section 35 is the largest at the first casing end 31 and opens at the first casing end 31. In this embodiment, the diameter (D11) of the first casing end 31 is 3.8 cm. The diameter (D12) at a smallest end of the converging section 35 is 0.778 cm. In other embodiments, the angle (A1) may range between 18 and 30 degrees.
The constricted uniform width section 36 has a substantially cylindrical cross section, and a length (L12) of the constricted uniform width section 36 is measured from a smallest end of the converging section 35 to the second casing end 32. In this embodiment, the length (L12) is 1.0 cm. The constricted uniform width section 36 has a diameter (D21) of 0.778 cm.
The gas intake unit 4 includes a mounting part 41, a protrusion 42, a gas channel 44, and a connection tube 43. The mounting part 41 is mounted to and closes the first casing end 31. The protrusion 42 projects and tapers from the mounting part 41 into the flow passage 33. The gas channel 44 extends through the mounting part 41 and the protrusion 42, and communicates with the flow passage 33 for introducing the gas 22 into the flow passage 33. The connection tube 43 projects from the mounting part 41 opposite to the first casing ends 31 and communicates with the gas channel 44. An air supply tube 91 is sleeved on the connection tube 43.
As shown in
The liquid input unit 5 is tubular, and includes a narrowed tube portion 52, a widened portion 51 and a liquid channel 53. The narrowed tube portion 52 is integrally connected to the casing unit 3. The widened tube portion 51 is connected to the narrowed tube portion 52 opposite to the casing unit 3. The liquid channel 53 extends through the narrowed and widened tube portions 52, 51 and communicates with the flow passage 33 for introducing the liquid 21 into the flow passage 33. The liquid channel 53 has an open end proximate to the protrusion 42. In other embodiment, the liquid input unit 5 may be snappingly engaged to the casing unit 3.

The support unit 6 integrally connects and projects outwardly from the second casing end 32 in the flowing direction (d1) of the flow passage 33, and includes a mounting ring 61, and a plurality of spaced apart ribs 621, specifically two ribs 621. The mounting ring 61 is spaced apart from the second casing end 32. The two ribs 621 connect the mounting ring 61 to the second casing end 32. In other embodiment, the support unit 6 may be snappingly engaged to the casing unit 3.

As shown in
The protrusion 42 serves as a guide to help whirling of the liquid, thereby increasing the whirling effect of the liquid 21. Therefore, although a total length of the flow passage 33 is only 4.1 cm, by virtue of the protrusion 42, a sufficient fluid force can be generated in the flow passage 33 to mix the gas 22 with the liquid 21 for producing sufficient bubbles. In this embodiment, the protrusion 42 has a frustoconical shape that has an excellent effect to produce a vortex flow. However, the protrusion 42 may also have a pyramidal shape with a polygonal base such as a three-sided, four-sided or five-sided base.
Because the direction (d2) of the liquid in the liquid channel 53 is inclined to the flowing direction (d1) in the flow passage 33 and because the channel central axis 531 of the liquid channel 53 is eccentrically offset from the passage central axis 34 of the flow passage 33, when the liquid 21 is introduced into the flow passage 33, a vortical force of the liquid 21 and the gas 22 is increased in the flow passage 33 to enhance the outlet flow rate of the liquid 21 and the gas 22 and the producing efficiency of bubbles.
