Detailed Description

In order to make the objects, features and advantages of the present utility model more comprehensible, the technical solutions in the embodiments of the present utility model are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. It is noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the present utility model provides a microbubble generator, including a generator body 1, wherein two end surfaces of the generator body 1 are respectively provided with a water inlet 11 and a water outlet 12, and a water flow channel 2 is formed between the water inlet 11 and the water outlet 12; the preset position of the water flow channel 2 is provided with an air flow channel 3 communicated with the water flow channel 2; the cross-sectional area of the air flow channel 3 gradually decreases in the flow direction of the air flow.

With reference to fig. 2, two groups of dark arrows in the vertical direction in the drawing are respectively a water inlet 11 and a water outlet 12, and the directions of the arrows are the flowing directions of water flow; wherein the light arrows in the generator body 1 are the flow direction of the air flow.

It should be noted that, the cross-sectional area of the airflow channel 3 gradually decreases, so when the airflow flows along the airflow channel 3, the airflow is coarsely thinned to accelerate the airflow velocity, so that the airflow forms a vacuum area at the intersection of the airflow channel 3, the vacuum area generates an adsorption force, so that the air is sucked into the water flow to generate micro bubbles, the diameter of the bubbles is smaller, and a mixture of the bubbles and the water flow is formed after the bubbles are converged into the water flow, namely the bubble water with a washing effect.

The working principle of the utility model is as follows: when the high-speed water flow is injected through the water inlet 11, when the water flow flows along the water flow channel 2, the air flow simultaneously enters the air flow channel 3, air bubbles are generated when the air flow enters the water flow channel 2 along the air flow channel 3, and the water flow mixed air bubbles flow out from the water outlet 12; wherein, as the airflow is coarsely thinned along the airflow channel 3 to accelerate the airflow velocity, a Venturi tube effect is formed, and the air is sucked into water to generate micro bubbles to act on a target object, thereby playing a role of washing; compared with the washing equipment in the prior art, the micro-bubble generator reduces the diameter of generated bubbles through the structural design of the airflow channel 3, and is beneficial to improving the washing effect.

In the embodiment, the water inlet 11 is provided with the ejector 4, the ejector 4 is provided with the water injection hole 41, the water inlet 11 is arranged at one end of the water injection hole 41, and the water injection hole 41 is communicated with the water flow channel 2; the water injection hole 41 has a sectional diameter gradually decreasing in the direction of the water flow in the water flow path 2.

It should be noted that, the water injection hole 41 in this embodiment is located at the first half section of the water flow channel 2, when water flows in the water injection hole 41, the water flow cross-sectional area gradually decreases, and the flow speed increases, so that the water flow flowing out from the outlet of the ejector 4 is high-speed water flow, so as to be capable of forcefully impacting the air flow, and forming a mixture of bubbles and water flow.

Further, the first end surface of the generator body 1 is provided with a mounting hole 141, and the ejector 4 is mounted in the mounting hole 141; the outer side wall of the ejector 4 is sleeved with a first sealing ring 5, and the first sealing ring 5 is abutted against the inner wall of the mounting hole 141.

In this embodiment, the number of the ejectors 4 is plural, and the first end surface of the generator body 1 is provided with a plurality of mounting holes 141, and each ejector 4 is respectively mounted in the corresponding mounting hole 141.

Referring to fig. 3, the number of the ejectors 4 in the scheme is two, and the two ejectors 4 are arranged side by side; in actual operation, the number of the ejectors 4 can be flexibly adjusted according to the needs, such as three or four, wherein the preferred arrangement mode is that a plurality of ejectors 4 are uniformly arranged along the axle center of the end face of the generator body 1.

As a preferable aspect of the present embodiment, a clearance space is formed between an end of the ejector 4 remote from the water inlet 11 and the inner wall of the mounting hole 141, and the air flow passage 3 is provided in the clearance space. A gap space is arranged at one port of the ejector 4, and the sectional area of the gap space is larger than that of the port of the water injection hole 41, so that the pressure intensity is reduced when water flows from the port of the water injection hole 41 into the gap space;

when the jet device works, water enters the jet device 4 from the water inlet 11, the flow speed of the water is accelerated through the jet device 4, the pressure at the periphery of the port of the water injection hole 41 of the jet device 4 is reduced after the flow speed is accelerated, so that the air is pressed into the water by the external atmospheric pressure, and then micro bubbles are sucked into the water flow by combining with the Venturi tube effect of the airflow channel 3, so that a mixture of the water flow bubbles is formed.

In this embodiment, the generator body 1 includes an outer casing 13, and a casing assembly sleeved in the outer casing 13; an intake passage 7 is formed between the outer housing 13 and the housing assembly, and the intake passage 7 communicates with one end of the airflow passage 3. As shown in fig. 2, the air inlet channel 7 is an annular flow channel arranged at the periphery of the shell assembly, and plays a role in air inlet through the air inlet channel 7.

Illustratively, the housing assembly includes an upper housing 14, and a lower housing 15 threadably coupled to the upper housing 14; a second sealing ring 16 is sealingly arranged between the upper housing 14 and the lower housing 15. The housing assembly comprises a detachably arranged upper housing 14 and a lower housing 15, wherein the two housings are connected by screw threads, and in order to ensure the tightness of the joint, a second sealing ring 16 is arranged between the two housings to improve the air tightness.

It is further explained that an end of the outer housing 13 is provided with a threaded connection 131 for connecting to a microbubble generator. Since the microbubble generator is usually installed at the water outlet 12 of the cleaning device, and thus needs to be connected with the cleaning device, the present embodiment is connected by means of screw rotation, and thus the preferred mode of the housing assembly of the present embodiment is set to be cylindrical.

As a preferable scheme of the embodiment, one end part of the water flow channel 2 near the water outlet 12 is provided with a steel mesh 6, and the steel mesh 6 is used for filtering water flow of the water flow channel 2. Wherein, the steel mesh 6 plays a role in filtering impurities in water flow on one hand; on the other hand, the bubbles with larger diameters cannot pass through the meshes of the steel mesh 6 and can be adsorbed on the steel mesh 6, so that the effect of filtering the bubbles with larger diameters is achieved.

The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
