Description

[0001] Apparatus of generating micro bubble [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a micro bubble generating device, and more particularly, to a micro bubble generating device installed in a faucet such as a home, a restaurant, or a food manufacturing facility to clean dishes, fruits, vegetables, .

MICRO BUBBLE refers to ultrafine bubbles which can not be visually recognized because they have a size of several micrometers or less, for example, 50 micrometers or less.

Conventional bubbles (bubbles, water droplets) present in water usually rupture on the surface of water after rising to the surface of water.

However, it is known that micro bubbles are extinguished by generating various energy while being reduced by pressure in water.

Therefore, microbubbles have been widely used in applications such as the use of improving the washing power, the cleaning application for doubling the effect of the bath, and the purification of the water quality.

For this reason, researches on micro bubble generator have been actively conducted.

The micro bubble generating device is roughly classified into a method using ultrasonic waves and a method based on mutual collision between water and air, and the latter method is widely used.

However, the technologies known to date are actually complicated and large-sized, so that it is difficult for the general public to handle them easily. Especially when it is difficult to use for cleaning fruits, vegetables or dishes in general households or restaurants, Improvement is urgent.

Of course, the number of the connection holes 121 is not limited to two but may be one or more.

A first suction path 122 communicating with the connection pipe 130 is formed in an upper end of the second body part 120.

The first suction passage 122 is a passage through which water supplied from a water supply connected to the connection pipe 130 flows into the interior of the first suction passage 122. The rotary body 200 to be described later is rotatably installed inside.

Here, a lid 150 is provided at the upper end of the second body part 120 to block the upper part of the first suction path 122.

A second suction path 111 is formed between the first body part 110 and the second body part 120 to allow air to flow through the upper end of the first body part 110.

The second suction passage 111 communicates with the bubble generation chamber 123 formed in the lower end of the second body portion 120 to move the air introduced from the outside to the lower portion of the second body portion 120 .

The bubble generation chamber 123 is formed in the lower end of the second body 120 and the bubble generation plate 400 to be described later is installed at the lower end of the bubble generation chamber 123, And the air introduced from the second suction passage 111 are mixed to generate micro bubbles.

The discharge passage 112 is a passage for discharging microbubble-generated water from the bubble generation chamber 123 to the lower portion of the first body 100, and the valve means 600 to be described later is installed.

The rotating body 200 is rotatably mounted on the first suction path 122 and is rotated when water flows in from the first suction port. Specifically, the rotating body 200 includes a rotating shaft 210 and a rotating blade 220 .

The rotary shaft 210 is vertically long and cylindrically shaped. The lower end of the rotary shaft 210 is rotatably mounted at an intermediate portion of the second body 120, and the suction fan 300, which will be described later, is mounted.

The rotary vane 220 is formed in a rectangular plate shape, which is formed concentrically with the rotary shaft 210 and radially protrudes about the rotary shaft 210 between the upper and lower circular plates.

The bubble generation plate 400 is formed with a plurality of nozzle units 410 protruding downwardly and open at an end thereof and a screw protrusion 420 is formed at an upper portion of the nozzle unit 410 .

More specifically, the nozzle unit 410 has a shape in which the milk bottle nipple is inverted upside down and is arranged in a circle of about 20 or so, and the lower end thereof is opened so that the water passes downward at a high pressure.

The screw protrusion 420 is formed by twisting the upper and lower ends of the '+' protrusion so as to be fixed on the upper portion of the nozzle unit 410.

Since the gap of the screw protrusion 420 is communicated with the upper portion of the nozzle unit 410, the air moving from the second suction path 111 to the bubble generation chamber 123 flows into the gap Is mixed with water moving from the first suction passage 122 to the bubble generation chamber 123 and is moved to the discharge passage 112 .

Further, a guide shaft 430 for guiding the backflow prevention plate 500, which will be described later, in the vertical direction is formed in the lower portion of the bubble generation plate 400.

3, when the pressure of the discharge passage 112 is equal to the pressure of the second suction passage 111, the check valve 500 is provided at the middle portion of the discharge passage 112 And the lower end of the second suction passage 111 is opened.

4, when the water pressure of the discharge passage 112 is greater than the air pressure of the second suction passage 111, the water in the discharge passage 112 rises along the guide shaft 430, And blocks the lower end of the second suction passage 111 to prevent the water in the bubble generation chamber 123 from flowing back to the second suction passage 111. [

As described above, the backflow prevention plate 500 is installed in the discharge passage 112 to prevent the backflow of water to the second suction passage 111, thereby improving the stability and quality of the product.

On the other hand, the valve means 600 is disposed below the discharge passage 112 to control the discharge mode of water.

More specifically, the valve means 600 includes a valve lower plate 610, a valve top plate 620, a shower substrate 630, and a valve spool 640.

The shower substrate 630 is connected to the first through hole 611 A plurality of second exhaust holes 632 are formed on the outer side of the first exhaust holes 631 to communicate with the second through holes 612. [

The shower substrate 630 is disposed at a lower portion of the valve lower plate and is fixedly mounted to the lower end of the first body 100 and a rubber packing 650 for improving water tightness is mounted on the outer peripheral surface.

The valve spool 640 is formed in a substantially rod shape and has one end protruding outward at the lower end of the first body 100, a center portion rotatably mounted to the valve lower plate 610, The upper portion is connected to the opening 621 and the lower portion is formed with a spool groove 641 which is selectively connected to the first through hole 611 or the second through hole 612.

As the valve spool 640 rotates, the spool groove 641 communicates any one of the first through hole 611 and the second through hole 612 with the opening hole 621, To the outside.

As shown in FIGS. 3 and 5, when water is discharged through the first through-hole 611, water flows out through the shower substrate 630 in the form of a direct water stream. 7, when the valve spool 640 rotates so that the spool groove 641 is connected to the second through hole 612 and water is discharged to the second through hole 612, (630). ≪ / RTI >

Since the valve means 600 is provided at the lower portion of the discharge path 112 as described above, the water stream can be selected in the form of a straight line or a spray line, thereby making it easy to use.

3, when the water flows into the first suction passage 122 through the connection pipe 130, the microbubble generator according to the embodiment of the present invention, (200) rotates and simultaneously rotates the suction fan (300).

Then, water is introduced into the bubble generating chamber 123 from the first suction passage 122 and air is introduced into the bubble generating chamber 123 through the second suction passage 111.

The water and air introduced into the bubble generation chamber 123 are crushed and mixed while passing through the bubble generation plate 400 to generate micro bubbles.

The microbubble-containing water passes through the open hole 621 of the valve top plate 620 and is discharged to the first discharge hole 631 or the second discharge hole 632 of the shower substrate 630.
