Description

Bubble generating device

The present invention relates to a bubble generating device, and more particularly to a bubble generating device for generating microbubbles in a liquid flowing therethrough.

Today's micron-sized water bubbles have been widely used in various fields. When micron-sized bubbles rupture in water, they release a lot of energy and cause the temperature to rise sharply and release free radicals. The temperature can be as high as 2000K, called sonoluminescence, and finally the high temperature and generated Free radicals achieve the effects of sterilization and destruction of organic matter.

The manner in which microbubbles are generally produced is by ultrasonic excitation or, as in U.S. Patent No. 2009001320, the method of shearing large bubbles to produce microbubbles.

However, whether it is ultrasonic excitation or shear generation of microbubbles, it requires a large equipment and driving energy and cannot be easily carried or used, which will limit the application range of microbubbles.

Therefore, the object of the present invention is to provide a bubble generating device capable of generating microbubbles in a liquid without any additional energy and being convenient to carry. .

Therefore, the novel bubble generating device comprises a tube body and a blocking portion.

The pipe body defines a pipe having an inlet and an outlet respectively at both ends, and a pressing portion extending from the inlet and gradually decreasing in inner diameter toward the outlet, and extending from the pressing portion a communicating portion having a uniform diameter, and a decompressing portion extending from the communicating portion to the outlet and gradually expanding toward the inner diameter of the outlet, allowing liquid to flow through the duct and being gradually pressurized and connected in the pressurizing portion The portion maintains a certain pressure and is gradually depressurized via the pressure reducing portion to form micron-sized bubbles in the liquid.

A barrier is provided to the tube and is located at the outlet of the conduit. The barrier includes at least one barrier wall and the barrier wall defines a flow guiding channel. The barrier wall provides the liquid impact. The flow guiding channel directs the liquid to form a vortex.

Preferably, the blocking portion is a vane having a plurality of blades, and the vane is rotatably disposed on the tubular body. Each blade of the vane is a blocking wall, and a guiding channel is defined between each two adjacent barrier walls.

Preferably, the blocking portion comprises a plurality of barrier walls, each barrier wall having a curved surface, and the curved surfaces of the blocking walls cooperate to define the flow guiding channels.

The utility model has the advantages that the pressing portion of the pipe cooperates with the decompressing portion, so that a large amount of micron-sized bubbles are formed in the process of pressurizing and then decompressing the liquid flowing through the nozzle, and then blocking The setting of the part increases the number of water bubbles of the micron level, and the nozzle is small in size and does not need to be Drive energy is added to achieve convenient carrying and use.

The other features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments, wherein: FIG. 1 is a cross-sectional view illustrating a preferred embodiment of the novel bubble generating device, wherein A blocking portion of the bubble generating device is illustrated; and Figure 2 is a cross-sectional view showing the preferred embodiment including a casing encased in the bubble generating device and an outer casing outside the blocking portion.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to Figure 1, the novel bubble generating device is for assembly in, for example, a liquid piping system for allowing liquid to pass and increasing the amount of microbubbles in the liquid. A preferred embodiment comprises a tubular body 1 and a blocking portion. 2.

The pipe body 1 defines a pipe 11. The pipe 11 has an inlet 111 and an outlet 112 at both ends, and a pressing portion 113 extending from the inlet 111 and tapered in the direction of the outlet 112, and a connecting portion extending from the pressing portion 113 and having the same inner diameter. 114, and a pressure reducing portion 115 extending from the communicating portion 114 to the outlet 112 and expanding inward in the direction of the outlet 112.

The barrier 2 is connected to the tubular body 1 and is located at the outlet 112 of the conduit 11. In the preferred embodiment, the barrier 2 is a vane having a plurality of vanes. The barrier wall 21 includes four barrier walls 21. Each barrier wall has a curved surface A flow guiding channel 211 is defined between each two adjacent barrier walls 21. The liquid from the tube 1 will impinge on the barrier wall 21, increasing the number of micron-sized bubbles in the liquid. Finally, the liquid is guided through the flow guiding passage 211 to generate a vortex and eject. The number of the barrier walls 21 in the preferred embodiment is four, but not limited to four, and may be two, three or more. The blocking portion 2 may also comprise only one barrier wall 21.

At the time of use, the liquid flows through the pipe 11 from the inlet 111 to the outlet 112, is gradually pressurized by the pressurizing portion 113, and after the constant pressure is maintained in the communicating portion 114, the pressure is gradually reduced by the pressure reducing portion 115, and the pressure is reduced. During the process, many micron-sized bubbles and relatively large micron-sized bubbles are formed in the liquid. When the liquid flows through the blocking portion 2, the bubbles having a larger micron level are split into micron-sized bubbles by the barrier wall 21 of the impact blocking portion 2, thereby greatly increasing the number of micron-sized bubbles in the liquid, and at the same time, the liquid can generate eddy currents. The range in which the liquid is ejected from the barrier 2 is larger.

When the liquid flows through the barrier wall 21, eddy current is generated due to the curved shape of the barrier wall 21.

The barrier wall 21 of the blocking portion 2 in the preferred embodiment may specifically be a blade that is freely rotatable and has a plurality of blades or a blade or wall structure integrally connected to the pipe body 1, and functions to block liquid flow. In the second portion, it is within the scope of the present invention to provide a fluid impact so that the bubbles in the liquid are further split into micron-sized bubbles by the impact, and the fluid can also be guided by the flow guiding passage 211 to form a vortex.

Referring to FIG. 2, in order to facilitate assembly in, for example, a piping system, the bubble generating device may further include a casing 3 covering the outside of the pipe body 1 and the blocking portion 2. The outer casing may be formed by molding a plastic material around the tubular body 1 and the blocking portion 2, and a connecting structure 31 such as a thread or other hooks or buckles may be formed at both ends of the outer casing 3 for coupling with other pipelines.

As described above, the pressurizing portion 113 and the communicating portion 114 that pass through the duct 11 cooperate with the decompressing portion 115, so that the liquid flowing through the nozzle is pressurized and then decompressed to form micron-sized bubbles. By the arrangement of the blocking portion 2, the number of micron-sized bubbles is greatly increased, and the nozzle volume is small, and the driving energy is not required, so that the utility model can be easily carried and used, so that the object of the present invention can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
