Description

Technical Field

[0001] The invention relates to a micro-bubble generating device. Background Art

[0002] Currently, the most common bubble water is based on the Venturi suction principle. However, although the existing structure can achieve the water-gas mixing effect, the use of the Venturi principle for suction makes the bubbles in the water very large. At the same time, the current rotary cutting structure does not produce enough microbubbles. In order to enhance the deep cleaning effect of the water body, due to the large amount of microbubbles, an air pump or the like is required, which has a complex structure. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] References herein to "one embodiment" or "embodiment" refer to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. In describing the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," and the like, which indicate orientations or positional relationships based on those shown in the accompanying drawings, are intended solely for ease of description and simplification of the present invention and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not intended to indicate or imply relative importance or to implicitly specify the number of the technical features referred to. Thus, a feature designated "first" or "second" may explicitly or implicitly include one or more of the features. Furthermore, the terms "first," "second," and the like are used to distinguish similar objects and are not necessarily intended to describe a specific order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0023] Referring to the drawings of the specification, a micro-bubble generating device includes a body 10, a water outlet 11 is provided at the lower end of the body, and the water outlet is a mesh-shaped water outlet. The upper end of the body is provided with a water inlet 12, and the upper end of the body is provided with an air duct 20 communicating with the inside and outside of the body. The air outlet end of the air duct is located in the middle of the water outlet end of the water inlet. In one embodiment, the water inlet is annularly distributed at the upper end of the body, and the air outlet end of the air duct is located in the middle of the water inlet and outlet ends. A partition is provided in the body. Plate 30, the partition divides the interior of the main body into an upper chamber 13 and a lower chamber 14. In the present invention, water flows in from the water inlet and the vertical water inlet straight channel described below, and remains in the upper chamber. At the same time, through the principle of Venturi, gas also flows from the air duct into the upper chamber for mixing. The partition is provided with a through hole 31 connecting the upper chamber and the lower chamber. The water inlet end of the through hole is connected to the air outlet end of the air duct and the water outlet end of the water inlet. At least two layers of partition nets 40 distributed up and down are provided in the lower chamber, and a gasket 50 is provided between the partition nets.

[0024] In a preferred embodiment of the present invention, the through hole is a tapered mouth, and the diameter of the inlet end of the through hole is larger than the diameter of the outlet end. In this way, after the water flows into the upper chamber, the direction of the incoming water will not flow out directly from the through hole, but will rotate on the conical surface. In this way, the incoming water rotates in the upper chamber, which can cut the gas entering the upper chamber and cut the gas into smaller pieces, so that the small bubbles are fully mixed with the water flow.

[0025] Furthermore, the air duct includes a horizontal air duct 21 and a vertical air duct 22 connected to each other, and the air inlet end of the air duct is located on the peripheral side of the body.

[0026] Specifically: the water outlet end of the through hole and the water inlet end of the water outlet hole are both provided with a partition net. Referring to the attached figure of the specification, the mixed water (a mixture of gas and water) coming out of the through hole first enters the partition net, enters the partition net again after passing through the gasket, and directly discharges from the water outlet hole after passing through the last layer of partition net. Three layers of partition nets are drawn in the figure, the first and third layers are respectively at the water outlet end of the through hole and the water inlet end of the water outlet hole. Two gaskets are also provided. These gaskets are located on the peripheral side of the partition net and can be connected with the internal peripheral wall of the main body.

[0027] In one embodiment, a vertical water inlet straight channel 15 is further provided on the main body, and the water outlet end of the water inlet straight channel is connected to the upper chamber. The water inlet straight channel can also be distributed in a ring shape at the upper end of the main body, which is located at the inner periphery of the water inlet and the outer periphery of the vertical air channel.

[0028] Furthermore, the water inlet is an inclined port, so that a rotating water flow can be formed after the water enters the upper chamber.

[0029] More specifically, the main body comprises an upper body 16 and a lower body 17. The water inlet and air duct are located on the upper body, while the water outlet is located on the lower body. An annular flange 18 is provided on the inner periphery of the lower end of the upper body. The outer periphery of the annular flange 18 mates with the inner circumferential wall of the upper end of the lower body. An annular groove 32 mates with the annular flange on the outer circumferential wall of the upper end of the partition. The outer circumferential wall of the partition mates with the inner circumferential wall of the lower body. The lower end surface of the upper body is sealed with the upper end surface of the lower body.

[0030] In the present invention, the gasket and the partition are stacked and placed in the lower body, and then the partition is placed on the partition, and the upper body is buckled into the lower body to complete the installation; in one embodiment, a boss 19 can be provided on the inner peripheral wall of the body for placing the partition, and at the same time, the partition is also sealed and connected to the inner peripheral wall of the annular flange.

[0031] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
