Microbubble jet nozzle device for pollutants removal {microbubble jet nozzle device for pollutants removal}

The present invention relates to a nozzle device, and more specifically, to clean contaminants by quickly generating a large amount of microbubbles using a non-powered method, thereby enabling smooth removal of contaminants from the cleaning object through the injection of a fluid containing microbubbles. It relates to a microbubble jet nozzle device for

Skin, food, clothing, and machine parts can be contaminated by various substances.

For example, skin may be contaminated by cosmetics, etc., and foodstuffs may be contaminated by microorganisms or residual pesticides.

Accordingly, washing is performed to remove contaminants from skin, food, clothing, and machine parts.

At this time, when washing was performed using general washing water such as tap water, there was a problem in that the removal of contaminants did not meet expectations.

For this reason, washing is performed using washing water containing a large amount of bubbles.

Bubbles penetrate and burst into the object to be cleaned, and contaminants are separated by the pressure applied when the bubbles burst. As a result, cleaning power can be improved, and contaminants can be removed more smoothly than when using general washing water.

However, regular bubbles having a mm size had a problem of difficulty penetrating into minute areas such as skin pores, and in particular, as shown in Figure 1, a gap occurred between one of the regular bubbles 200' and the other. As the surface area that can come into contact with the contaminants 500 present in the cleaning object 600 decreases, the cleaning efficiency decreases.

Accordingly, recently, there has been an increasing number of cases where washing is performed using washing water containing bubbles, and washing water containing microbubbles having a size of μm .

Microbubbles are extremely small in size and can penetrate deeply into every nook and cranny of the object to be cleaned, such as the pores of the skin, thus allowing more smooth removal of contaminants.

Meanwhile, microbubbles can be generated by various 'microbubble generating devices' such as those disclosed in Korean Patent Publication No. 10-2019-0031012.

However, the majority of conventional microbubble generating devices generate microbubbles in still water by transmitting power to an ultrasonic generator placed within the housing. As a power device is required, the cost and hassle of preparing and installing it is increased. There was a problem of contamination, and there was a problem of contaminants remaining in the housing after cleaning reaching the object to be cleaned during the subsequent cleaning process, causing re-contamination of the object to be cleaned.

To solve this problem, a 'non-powered microbubble generator' such as a type including a spiral flow path or a single venturi tube with a skirt-shaped cross section has been proposed.

However, the conventional non-powered microbubble generator including a spiral flow path has a complicated structure due to the spiral flow path, making manufacturing and management inconvenient.

In addition, the conventional non-powered microbubble generator, which includes a single venturi tube with a skirt-shaped cross section, had a problem in that the amount of bubbles produced did not meet expectations, and water consumption increased because a significant amount of water was required to be introduced. There was a problem that durability and sealability were reduced due to the air inlet being required.

For the above reasons, attempts are being made in the field to develop a nozzle device that not only improves durability and sealability, but also allows a large amount of microbubbles to be quickly generated by a non-powered method. However, satisfactory results have not been obtained to date. This is the situation.

Republic of Korea Patent Publication No. 10-2019-0031012

The present invention was proposed to solve the problems of the prior art as described above. By quickly generating a large amount of microbubbles using a non-powered method, contaminants can be smoothly removed from the cleaning object through the injection of a fluid containing microbubbles. The purpose is to provide a nozzle device that allows

In order to achieve the above object, the present invention,

A connecting member connected to a fluid supplier and providing a flow path for the fluid supplied from the fluid supplier; a receptor that communicates with the connecting member and receives the fluid flowing through the connecting member; It is disposed radially in communication with the receptor, but the diameter of the distal end located farther from the receptor is formed to be larger than the diameter of the distal end through the change in fluid flow rate and internal pressure due to the difference in diameter between the distal end and the distal end. a plurality of expansion tubes that induce microbubble generation; a discharge pipe that communicates with each of the expansion pipes and discharges the fluid flowing in through each of the expansion pipes; We propose a microbubble jet nozzle device for cleaning contaminants, comprising a housing for accommodating the connecting member, the receptor, the expansion tube, and the discharge tube.

The fluid supplier may be a faucet or shower.

The diameter of the distal end of the expansion tube may be 2.5 to 4 times the diameter of the distal end.

The discharge pipe may include a net built into one end adjacent to the expansion pipe.

The opening/closing rate of the mesh may be 20 to 40%.

In the housing, the connection member connection portion may be formed to have a smaller diameter than other portions.

The present invention may further include a circulation pipe that communicates with the receptor and circulates the fluid contained in the receptor.

The length of the circulation tube may be 0.5 to 0.9 times the length of the expansion tube.

The circulation pipe is formed in the form of a straight pipe with one end closed and arranged as a single piece in the center of one side of the receptor, and is formed in the form of a straight pipe with one end closed and arranged radially on one side of the receptor or formed in a 'U' shape. It can be placed singly in the center of one side of the receptor.

The microbubble jet nozzle device for cleaning contaminants according to the present invention is disposed radially in communication with the receptor, and includes a plurality of expansion tubes in which the diameter of the distal end located farther from the receptor is larger than the diameter of the distal end. As the fluid flowing in from the receptor reaches the distal end of each expansion tube, the flow rate of the fluid decreases due to the difference in diameter and the internal pressure increases. As a result, a large amount of micro bubbles can be quickly generated without a separate power device. As the fluid containing bubbles is sprayed onto the object to be cleaned, contaminants can be smoothly cleaned.

The microbubble jet nozzle device for cleaning contaminants according to the present invention includes a connecting member. By connecting the connecting member to a fluid supplier, such as a faucet or shower, fluid can be smoothly supplied to the expansion pipe.

The microbubble jet nozzle device for cleaning contaminants according to the present invention may further include a circulation pipe in communication with the receptor, and as the fluid contained in the receptor circulates and flows turbulently through the circulation pipe, the amount of dissolved oxygen contained in the fluid is adjusted. Since this can be increased, microbubble generation in the expansion tube can be more smooth.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

In the description below, 'tip' refers to the longitudinal end located in the fluid inflow direction, and 'end' refers to the longitudinal end located in the fluid outflow direction.

As shown in Figure 2, the microbubble jet nozzle device (A) for cleaning contaminants according to the present invention includes a connecting member (10); receptor (20); Extension tube (30); discharge pipe (40); and housing 50.

The connecting member 10 of the present invention is connected to the fluid supplier 100 and provides a flow path for the fluid supplied from the fluid supplier 100.

At this time, the connecting member 10 is provided with a fastener 11 at one end, so that the connection with the fluid supply 100 can be easily accomplished by fastening the fastener 11 to the fluid supply 100.

Here, the fastener 11 may be of any conventional structure and method as long as it can be stably fastened to the fluid supplier 100 by thread engagement, etc., and a detailed description of the fastener 11 will be omitted.

Meanwhile, the connecting member 10 can be freely bent because it is made of a flexible material.

Additionally, the fluid supply device 100 to which the connecting member 10 is connected may be of any type as long as it is capable of supplying fluid. Examples of the fluid supply device 100 may be a faucet or a shower device.

The receptor 20 of the present invention communicates with the connecting member 10 and receives fluid flowing in through the connecting member 10.

Since this receptor 20 is formed in a cylindrical shape and only accommodates fluid, it has no special function, so a detailed description of the receptor 20 will be omitted.

A plurality of expansion tubes 30 of the present invention are arranged radially in communication with the receptor 20.

At this time, the diameter of the distal end (30b) of each of the expansion tubes (30) located further away from the receptor (20) is larger than the diameter of the distal end (30a).

Therefore, the fluid containing dissolved oxygen flows into the expansion tube 30 from the receptor 20, and bubbles can grow in the process of passing through the tip 30a with a relatively small diameter, and the distal end with a relatively large diameter ( In the process of passing through 30b), the bubbles are ruptured small due to shear force due to the flow velocity gradient, thereby generating a plurality of microbubbles 200 with a size of, for example, 10-100 μm .

Here, if the diameter of the distal end 30b of the expansion tube 30 is less than 2.5 times the diameter of the distal end 30a, the decrease in fluid flow rate and the increase in internal pressure within the distal end 30b may be minimal, and the distal end of the expansion tube 30 (30b) If the diameter exceeds 4 times the diameter of the distal end (30a), the generation of microbubbles 200 may be rapidly reduced, so the diameter of the distal end (30b) of the expansion tube (30) is 2.5 to 4 times the diameter of the distal end (30a). It is desirable.

For example, when the diameter of the distal end 30a of the expansion tube 30 is 0.8 to 2 mm, the diameter of the distal end 30b of the expansion tube 30 may be 2 to 5 mm.

In addition, if the length ratio between the distal end 30a and the distal end 30b of the expansion tube 30 is less than 0.6 times or exceeds 1.5 times, the generation of microbubbles 200 may be rapidly reduced, so the distal end 30a of the expansion tube 30 It is preferable that the length ratio of the end portion 30b is 0.6 to 1.5 times.

Meanwhile, there is no limit to the number of expansion tubes 30, but as the number increases, miniaturization becomes difficult, so it is preferable to provide 3 to 6 expansion tubes.

The discharge pipe 40 of the present invention communicates with each of the expansion pipes 30 and discharges fluid flowing in through each of the expansion pipes 30.

At this time, the discharge pipe 40 includes a mesh 41 built into one end adjacent to the expansion pipe 30, so that the fluid flowing into the discharge pipe 40 can be discharged uniformly as it is dispersed through the mesh 41. there is.

Here, if the opening/closing ratio of the mesh 41 is less than 20% or exceeds 40%, the amount of micro bubbles 200 generated may be reduced due to a decrease in the deceleration effect of the flowing fluid, so the opening/closing ratio of the mesh 41 is It is preferable that it is 20 to 40%.

The housing 50 of the present invention accommodates the connecting member 10, the receptor 20, the expansion pipe 30, and the discharge pipe 40.

This housing 50 only accommodates the connecting member 10, the receptor 20, the expansion pipe 30, and the discharge pipe 40 and does not have a special function. Detailed description of the housing 50 is omitted.

However, the connection portion of the connecting member 10 in the housing 50 is formed to have a smaller diameter than other portions, so that gripping can be easily performed by grasping the portion.

Additionally, the microbubble jet nozzle device (A) for cleaning contaminants may further include a circulation pipe (60) in communication with the receptor (20).

Therefore, as the fluid contained in the receptor 20 circulates through the circulation pipe 60 and flows in turbulent flow, the amount of dissolved oxygen contained in the fluid may increase, making the creation of micro bubbles 200 in the expansion pipe 30 more smooth. You can.

At this time, the shape and arrangement of the circulation pipe 60 may be various.

For example, the circulation pipe 60 is formed in the form of a straight pipe with one end closed and can be placed singly in the center of one side of the receptor 20 or radially disposed on one side of the receptor 20, and is formed in a 'U' shape. It can be placed singly in the center of one side of the receptor 20.

However, if the length of the circulation pipe 60 is less than 0.5 times or more than 0.9 times the length of the expansion pipe 30, the circulation of the fluid may be insufficient, so the length of the circulation pipe 60 is 0.5 times the length of the expansion pipe 30. ~0.9 times is preferred.

A detailed description of the injection of fluid containing microbubbles 200 through the microbubble 200 jet nozzle device (A) for cleaning contaminants 500 according to the present invention is as follows.

As shown in FIG. 3, the connecting member 10 of the present invention is connected to a fluid supplier 100, for example, a faucet or shower, and the fluid supplied from the fluid supplier 100 is used to clean the contaminants 500 according to the present invention. Micro bubbles 200 are introduced into the jet nozzle device (A).

At this time, the connecting member 10 is provided with a fastener 11 at one end, and the connection with the fluid supply 100 can be easily made by fastening the fastener 11 to the fluid supply 100.

And in the present invention, as shown in FIG. 4, a plurality of expansion pipes 30 are radially disposed on one side of the receptor 20 for accommodating the fluid flowing in through the connecting member 10. Fluid flows into each expansion pipe (30).

Here, the expansion tube 30 has a diameter of the distal end 30b, which is located farther from the receptor 20, larger than the diameter of the distal end 30a, so that the fluid containing dissolved oxygen flows from the receptor 20. Bubbles may grow in the process of flowing into the expansion pipe 30 and passing through the tip 30a of a relatively small diameter, and the shear force due to the flow velocity gradient in the process of passing through the distal end 30b of a relatively large diameter. As the bubbles are smallly ruptured, a plurality of microbubbles 200 may be generated.

And in the present invention, the discharge pipe 40 communicates with each of the expansion pipes 30, and the fluid in which microbubbles 200 are generated in the process of flowing along the expansion pipe 30 is discharged to the outside by the discharge pipe 40. It can be.

Therefore, as shown in FIG. 8, by directing the fluid containing microbubbles 200 discharged through the discharge pipe 40 to the cleaning object 600, the microbubbles 200 penetrate into every corner of the cleaning object 600. As shown in Figure 9, since the contaminants 500 are in close contact with each other and the contaminants 500 are separated, the contaminants 500 can be removed smoothly.

For example, by spraying a fluid containing microbubbles 200 discharged through the discharge pipe 40 onto the skin, as shown in FIG. 10, the microbubbles 200 penetrate the pores 400 of the skin and remain in the pores 400. Removal of cosmetic particles 300, etc. can be performed smoothly.

At this time, the discharge pipe 40 includes a mesh 41 built into one end adjacent to the expansion pipe 30, and the fluid flowing into the discharge pipe 40 is distributed uniformly as it passes through the mesh 41. Therefore, when the fluid containing the microbubbles 200 is especially sprayed onto the skin, the fluid containing the microbubbles 200 is prevented from being concentrated on a part of the skin, so skin irritation can be minimized.

However, if the generation of micro bubbles 200 in the expansion tube 30 is insufficient, the cleaning effect, that is, the effect of removing contaminants 500, may be reduced.

However, the present invention communicates with the receptor 20, but is formed in the form of a straight pipe with one end blocked as shown in FIG. 5, and is disposed singly in the center of one side of the receptor 20, and one end as shown in FIG. 6. A circulation pipe 60 formed in the form of a closed straight pipe and arranged radially on one side of the receptor 20, or formed in a 'U' shape as shown in FIG. 7 and arranged singly in the center of one side of the receptor 20. It may further include, as the fluid accommodated in the receptor 20 circulates through the circulation pipe 60 and flows in turbulent flow, the amount of dissolved oxygen contained in the fluid may increase, thereby increasing the amount of dissolved oxygen in the expansion pipe 30. As the generation of bubbles 200 becomes more smooth, the generation of microbubbles 200 is sufficiently achieved, thereby further enhancing the cleaning effect of the object to be cleaned by spraying a fluid containing microbubbles 200.

Meanwhile, Figure 11 shows the results of foundation cleaning through fluid injection without bubbles (corresponding to 'normal' in the drawing) and the results of foundation washing through fluid injection including microbubbles 200 (corresponding to 'present invention' in the drawing). It is an example diagram showing the results of lipstick cleaning through fluid injection without bubbles (corresponding to 'normal' in the drawing) and fluid injection including microbubbles 200 (corresponding to 'present invention' in the drawing). This is an example showing the results of lipstick cleaning.

Through the above cleaning results, it can be confirmed that by spraying a fluid containing microbubbles 200, contaminants can be removed from the cleaning object 600 more smoothly than when spraying a fluid that does not contain bubbles.

Through the above explanation, it may appear that the fluid containing microbubbles 200 is only sprayed onto the skin, but the skin is only one of the cleaning objects 600, and the cleaning objects 600 include food, clothing, and machine parts in addition to skin. It can be various things.

The present invention as described above is not limited to the above-described embodiments, so changes can be made without departing from the gist of the present invention claimed in the claims, and such changes may be made to the present invention as defined by the claims below. falls within the scope of protection of the invention.
