Micro bubbles device

Abstract

The present invention relates to a microbubble machine, including: a pump, including a water inlet pipeline and a water outlet pipeline; and a microbubble device, connected to the water inlet pipeline, including an axial hole and an air inlet channel, the axial hole including an inlet and an outlet, and a port of the air inlet channel connected to the axial hole between the inlet and the outlet. Thereby, regardless of whether the water outlet pipeline is additionally connected to a nozzle (or other spraying device) or whether the water outlet is reduced, the gas (such as oxygen, ozone, air or other gas) will not be affected by the pressure change (back pressure) in the water outlet pipeline, and can effectively and smoothly enter the axial hole from the air inlet channel, and the gas can be fully and evenly mixed in the liquid.

Description

[Technical Field]

[0001] The present invention relates to a liquid-gas mixing device, and more particularly to a microbubble machine. [Previous Technology]

[0002] Generally, microbubble machines are widely used in various fields, such as industry, medical care, hygiene, food processing, agricultural water, and aquaculture farms. Microbubble machines use liquids (such as water) and air to generate bubbles, providing water purification and cleaning services.

[0003] A conventional microbubble machine includes a pump and a microbubble device, which allows gas to be introduced into a fluid pipeline to generate bubbles in the liquid. However, the microbubble device is connected to a water outlet pipeline. When the water outlet pipeline is connected to a nozzle (or other spraying device) or the water outlet is narrowed, the gas will be affected by the pressure change (back pressure) in the water outlet pipeline, which will affect the negative pressure suction effect. The amount of gas entering the water outlet pipeline will decrease, and the mixing effect between the gas and the liquid will be reduced or even lost.

[0004] Therefore, it is necessary to provide a novel and progressive microbubble machine to solve the above-mentioned problems. [Summary of the Invention]

[0005] The main objective of this invention is to provide a microbubble generator that can avoid being affected by pressure changes (back pressure) in the water outlet pipe, can effectively and smoothly draw in air, and the gas can be fully and evenly mixed in the liquid.

[0006] To achieve the above objective, the present invention provides a microbubble machine, comprising: a pump including a water inlet pipe and a water outlet pipe; and a microbubble device connected to the water inlet pipe, including a shaft hole and an air inlet channel, the shaft hole including an inlet and an outlet, and a port of the air inlet channel communicating with the shaft hole between the inlet and the outlet.

Implementation Method

[0007] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The words "a" or "at least one" preceding the terms mentioned herein are not intended to limit the quantity. Depending on the requirements, there may also be "multiple" items. This variation in quantity is also within the scope of protection, as will be stated in advance.

[0008] Please refer to Figures 1 to 4, which show one embodiment of the present invention. The microbubble machine 1 of the present invention includes a pump 10 and a microbubble device 20.

[0009] The pump 10 includes an inlet pipe 11 and an outlet pipe 12. The microbubble device 20 is connected to the inlet pipe 11. The microbubble device 20 includes a shaft hole 21 and an air inlet channel 22. The microbubble device 20 is a single integrally formed component. The shaft hole 21 includes an inlet 211 and an outlet 212. A port 221 of the air inlet channel 22 connects to the shaft hole 21 between the inlet 211 and the outlet 212. Since the microbubble device 20 is connected to the inlet pipe 11, regardless of whether the outlet pipe 12 is connected to a nozzle (or other spraying device) or whether the outlet is reduced, the gas (e.g., oxygen, ozone, air, or other gases) will not be affected by the pressure change (back pressure) in the outlet pipe 12. It can effectively and smoothly enter the shaft hole 21 from the air inlet channel 22, and the gas can be fully and uniformly mixed in the liquid.

[0010] In detail, the shaft hole 21 further includes a small diameter section 213 and a large diameter section 214 that are connected to each other. The port 221 of the air intake channel 22 is located in the large diameter section 214. When liquid flows from the small diameter section 213 to the large diameter section 214, a low pressure (negative pressure) effect is generated due to the expansion of space, thereby causing gas to be drawn into the shaft hole 21 from the air intake channel 22. Preferably, the small diameter section 213 gradually narrows from the inlet 211 toward the large diameter section 214. The port 221 of the air intake channel 22 is adjacent to the junction of the large diameter section 214 and the small diameter section 213. The small diameter section 213 and the large diameter section 214 form a constriction channel 215. The air intake channel 22 is connected to the constriction channel 215, thereby improving the low pressure (negative pressure) effect and more effectively drawing in gas.

[0011] More specifically, the small diameter section 213 includes a tapering section 216 and a constant diameter section 217. The small diameter section 213 tapers from the inlet 211 toward the large diameter section 214. The constant diameter section 217 is connected to the large diameter section 214. The large diameter section 214 includes multiple sections 218. The radial dimensions of the multiple sections 218 increase sequentially from the small diameter section 213 toward the outlet 212, thereby further enhancing the low pressure (negative pressure) effect. The microbubble device 20 also includes an external thread section 23 and an internal thread section 24. The external thread section 23 and the internal thread section 24 are located on opposite sides of the port 221 of the air intake channel 22. In this embodiment, the external thread section 23 and the internal thread section 24 are respectively configured corresponding to the small diameter section 213 and the large diameter section 214 for connecting other pipelines or devices (nozzles or other spraying devices).

[0012] Preferably, the microbubble device 20 further includes a flange 25, which extends from the small diameter section 213 toward the large diameter section 214 and is located within the radial projection range of the port 221 of the air intake channel 22. The flange 25 includes an outer surface 251, and there is an intervening space 252 between the outer surface 251 and the port 221 of the air intake channel 22. This allows the intervening space 252 to have a larger vacuum degree, thus providing a better low pressure (negative pressure) effect. Furthermore, the outer surface 251 is a ring-shaped inclined surface that extends obliquely inward from one end edge 219 of the large diameter section 214 into the large diameter section 214. The end edge 219 of the large diameter section 214 is spaced apart from the edge of the port 221 of the air intake channel 22 by a distance. The intervening space 252 gradually expands towards the large diameter section 214 to ensure that the intervening space 252 has a stable and good negative pressure effect. Preferably, the microbubble machine 1 also includes a flow adjustment device 30, which is connected to the air intake channel 22 and is used to adjust the air intake volume.

[0013] In another possible embodiment shown in FIG5, the small diameter section 213a may have a fixed radial dimension; the small diameter section 213a and the large diameter section 214a are at right angles without flanges, which can also provide a good low pressure (negative pressure) effect for gas intake; the microbubble device 20a further includes a quick-release connecting section 22a and an external thread section 23a, the quick-release connecting section 22a and the external thread section 23a are respectively configured corresponding to the small diameter section 213a and the large diameter section 214a, the quick-release connecting section 22a can be quickly assembled or separated with a quick-release connector, and the external thread section 23a can be connected to other pipelines or devices (nozzles or other spraying devices).
