In general, when pouring beer into a cup, bubbles are generated, which prevents the beer from coming into contact with oxygen, thereby preventing the carbon dioxide gas contained in the beer from being lost into the air and giving a visually pleasing feeling. It plays a role. Such bubbles are most preferably formed about 20-30% of the beer filled cup.

However, the conventional draft beer withdrawal device, although the foam is generated when pouring the draft beer in the cup, the foaming was not constant. Therefore, it was difficult to satisfy the various needs of the guests such as those who like a lot of bubbles or those who had a little bubble.

At this time, the first discharge hole 103 is formed in the discharge port 105 formed to extend downward from the lower portion of the valve body 100, the neck hole (smaller diameter than the lower portion in the upper portion of the second discharge hole 104) 106 is formed.

The inside of the space portion 101 is formed with a guide fitting seating jaw 107 in which the guide tool 501 of the switch guide 500 to be described later is formed, and the inlet side of the inlet hole 102 is connected to the fitting tool 600 to be described later. One end of the connection pipe 601 is inserted into the connector seating jaw 108 is formed.

On the other hand, a thread is formed in the outer upper portion of the space portion 101, the outer end of the inlet hole 102 and the lower end of the discharge port 105, so that the coupling nuts 503, 603 and 411, which will be described later, are respectively screwed together. do.

As shown in FIG. 2 and FIG. 3, the above-described first discharge hole switch 200 opens and closes the first discharge hole 103 formed in the lower portion of the valve body 100, and thus the space of the valve body 100. The first piston 201 is installed in the unit 101 so as to be lifted up and down, and is rotatably installed at the upper portion of the valve body 100 to open and close the first discharge hole 103 at the lower end thereof. It consists of a lever 202.

At this time, the lower end of the lever 202 is rotatably coupled to the upper portion of the first piston 201 exposed to the upper portion of the actuator guide 500 by the rotation pin 203. Rotating pin through hole 202a through which the rotating pin 203 penetrates at the lower end of the lever 202 and the upper portion of the first piston 201 with the upper portion of the first piston 201 inserted into the lower end of the lever 202. 201a are formed respectively.

A washer 204 for smoothly rotating the lever 202 is interposed between the lever 202 and the actuator guide 500, and the washer 204 has an upper portion of the first piston 201 penetrating therethrough. A falling rod through hole (not shown) through which the first piston through hole (not shown) and the descending rod 303 of the second discharge hole opening / closing device 300 to be described later is formed is respectively formed.

An open groove 201b is formed in the upper portion of the first piston 201, and a compression spring 205 is installed in the open groove 201b. The lower end of the compression spring 205 is fixed to the spring fixing pin 206 penetrating the lower portion of the opening groove 201b horizontally, the upper end is fixed to the outside of the rotation pin 203 in the opening groove 201b. It is fixed to the spring fixing plate 207.

A rotating pin through hole 207b through which the rotating pin 203 penetrates is formed at an upper portion of the spring fixing plate 207, and a spring fixing protrusion 207b is formed at the lower portion of the spring fixing plate 207 to fix the upper end of the compression spring 205. .

By such a coupling structure of the compression spring 205, the coupling relationship between the lever 202 and the first piston 201 is strengthened. That is, since the diameter of the pivot pin through hole 201b formed in the upper portion of the first piston 201 is larger than the diameter of the pivot pin 203, the first piston 201 flows up or down by the diameter difference, or vice versa. Although the rotating pin 203 and the lever 202 may move up and down about the piston 201, the coupling force between the lever 202 and the first piston 201 is caused by the compression force of the compression spring 205. Since it is firmly maintained, there is no fear that the lever 202 or the first piston 201 will flow up and down.

On the other hand, the shield member 208 for opening and closing the upper portion of the first discharge hole 103 is fixed to the outer side of the lower end of the first piston 201, the shield member 208 is made of a rubber material having elasticity and the like shield The upper portion of the member 208 is formed with a first piston insertion groove 208a into which the lower end of the first piston 201 is inserted.

In addition, a fixing protrusion 201c protrudes in the circumferential direction on the outer side of the lower end of the first piston 201 inserted into the first piston insertion groove 208a, and the inner side of the first piston insertion groove 208a corresponding thereto. The fixing protrusion insertion groove 208b into which the fixing protrusion 201c is inserted is formed.

The lower end of the shielding member 208 formed in this way is formed in a pointed shape to match the upper shape of the first discharge hole (103).

On the other hand, in the switch guide 500 is provided with a tension spring 209 is a force acting in the direction to lower the first piston 201, the upper end of the tension spring 209 of the switch guide 500 to be described later The lower surface of the tension spring 209 is in close contact with the bottom surface of the guide cover 502, and is in close contact with the tension spring contact plate 210 interposed outside the first piston 201 in the actuator guide 500.

At this time, the anti-rotation protrusion 201d is formed on the outer side of the first piston 201 to prevent the rotation of the tension spring contact plate 210, and the anti-rotation protrusion 201d inside the tension spring contact plate 210. ) Is inserted into the anti-rotation protrusion insertion groove (210a) is formed.

According to the first discharge hole switch 200 configured as described above, when the lever 202 is vertical, that is, in the home position, the first piston 201 is lowered so that the shielding member 208 of the first discharge hole 103 is closed. When the upper portion is shielded and the lever 202 is rotated forward, the first piston 201 is forcibly raised, so that the shielding member 208 is separated from the first discharge hole 103 so that the first discharge hole 103 is closed. Is opened.

As such, when the first piston 201 is raised, the tension spring 209 is in a compressed state. When the lever 202 is returned to its original state, the first piston 201 is moved by the restoring force of the tension spring 209. It descends to shield the first discharge hole 103 by the shielding member 208.

On the other hand, an airtight ring 211 is installed on the outside of the lower portion of the first piston 201 penetrating the switch guide 500 so that draft beer does not flow into the switch guide 500.

As shown in Figures 2 and 3, the second discharge hole opening and closing 300 is to open and close the second discharge hole 104 formed in the lower portion of the valve body 100, the win in the space 101 A second piston 301 that is strongly installed to open and close the second discharge hole 104 to the lower end, and a pusher 302, a pusher 302, and a second, which are installed on the inner side of the lever 202 in a liftable manner. Interposed between the piston 301 is pushed down by the pusher 302 and is composed of a lowering rod 303 for lowering the second piston 301.

In addition, a push button 304 for lowering the pusher 302 is provided outside the lever 202, and a guide slot 202b for guiding the lowering of the push button 304 is provided in the lever 202 in the vertical direction. It is formed long.

At this time, a through shaft 305 penetrating the upper portion of the pusher 302 is formed horizontally on the rear surface of the push button 304, and the through shaft 305 penetrates the upper portion of the pusher 302. The hole 302a is formed.

The through shaft 305 is elastically supported inside the guide slot 202a by the spring 306. Accordingly, when the push button 304 is pushed down by hand and then released, the push button 304 is raised to the original position by the restoring force of the spring 306, and the push button 302 is also raised to the original position.

A lower end of the second piston 301 is provided with a hermetic ring 307 is inserted into the neck hole 106 of the second discharge hole 104 to form a neck hole shielding portion 301a for shielding the neck hole 106. The neck portion 301b having a smaller diameter than the neck hole 106 is formed on the neck hole shielding portion 301a.

Accordingly, when the neck hole 106 is shielded by the neck hole shield 301 a and the neck hole shield 301 a is separated from the neck hole 106 by the lowering of the second piston 301, the neck part 301 b is the neck hole 106. The draft beer is discharged into a gap formed between the neck portion 301b and the neck hole 106.

The upper portion of the second piston 301 penetrates the bottom surface of the guide hole 501 of the actuator guide 500 to be described later, and is located in the guide hole 501. An inflow preventing stone 301c is formed in the circumferential direction to prevent the lower portion of the second piston 301 from flowing into the guide hole 501.

The second piston 301 is elastically supported by the spring 308 installed in the guide tool 501, so that the second piston 301 is raised by the restoring force of the spring 308 in a state where the pusher 302 is not lowered and thus the neck hole shielding part. 301a shields the neck hole 106.

The lower end of the spring contact hole 309 is fixed to the upper end of the spring 308, the elastic support for the second piston 301 is in close contact with the inner bottom surface of the guide sphere 501, the upper end of the second piston (301) Close to

Therefore, when the second piston 301 is lowered, the spring 308 is compressed by the spring contact hole 309 which is lowered at the same time, and then the restoring force of the spring 308 is removed when the force that is pressed against the second piston 301 is removed. As the spring contact hole 309 is pushed up, the second piston 301 is also raised.

On the other hand, since the hermetic ring 310 is mounted on the outer side of the upper portion of the upper portion of the guide piston 501 of the second piston 301, the draft beer does not flow into the guide sphere 501.

3, 5 and 6, the above-described bubble generator 400 is installed on the discharge passage of the draft beer discharged through the second discharge hole 104 through the second discharge hole 104 It is fixed by the bubble guide 410 by converting the draft beer discharged into the foam.

The bubble generator 400 is installed in the bubble guide hole 410a of the bubble guide 410 and the spray plate 401 having a plurality of fine holes 401a is formed therein to form the second discharge hole 104. Spray tube 402 for finely spraying the draft beer discharged through, and a plurality of expansion holes 403a which are installed on the lower side of the spray tube 402 and extended than the fine holes 401a of the spray plate 401 are formed The finely sprayed draft beer is composed of an expansion plate 403 to expand and produce bubbles.

At this time, the fine holes 401a and the expansion holes 403a are formed at regular intervals on the concentric circles, and the expansion holes 403a are formed in the form of long holes.

Herein, the diameter of the fine holes 401a is preferably 0.2 to 0.4 mm, most preferably 0.3 mm. If the diameter of the fine hole 401a exceeds 0.4mm, the size of the sprayed particles is too large, and if the diameter of the fine holes 401a is less than 0.2mm, it is difficult to pass draft beer. The shorter width of the expansion hole 403a is preferably 0.5 to 1.5 mm, most preferably 1 mm. If the width of the short side of the expansion hole 403a exceeds 1.5 mm, the particles of the foam are too large, and if the width of the expansion hole 403a is less than 0.5 mm, the particles of the foam are too small.

The upper end of the spray tube 402 is in close contact with the bottom surface of the neck hole 106 of the second discharge hole 104, and the lower end of the spray tube 402 is in close contact with the expansion plate 403. Here, the spray plate 401 is formed at a position spaced apart from the lower end of the spray tube 402 by a predetermined distance, the spray plate 401 and the expansion plate 403 is positioned to be spaced a predetermined distance.

On the other hand, one side of the bubble guide 410 is formed with a bubble generator 400 and a bubble guide hole 410a for guiding the discharge of bubbles generated from the bubble generator 400 is formed, the other side is the valve body 100 A discharge hole through hole 410b through which the discharge hole 105 of the filter penetrates is formed.

At this time, the bubble guide 410 is screwed into the lower end of the discharge port 105 in the state in which the discharge nut 105 through the discharge port through hole 410b, the lower portion of the valve body 100 Is coupled to. The upper side of the bubble guide hole 410a is inserted into the second discharge hole 104.

In addition, an expansion plate seating jaw 410c in which the expansion plate 403 is seated is formed inside the bubble guide hole 410a, and the coupling nut 411 is inserted into the lower portion of the discharge hole through hole 410b. At the lower end of the discharge port 105 is screwed.

On the other hand, because the fine holes 401a of the spray plate 401 and the expansion holes 403a of the expansion plate 403 produce small and fine bubbles (fine draft beer particles are discharged through the fine holes 401a). Even if it is expanded through the expansion hole 403a, the particles are constant and small), and the resulting foam can be maintained for a long time, and since the foam suppresses evaporation of the ingredients that give the draft beer the original taste, Can keep for a long time.

As illustrated in FIGS. 2 and 3, the above-described actuator guide 500 guides the operation of the first discharge hole actuator 200 and the second discharge hole actuator 300, and the valve body 100 of the valve body 100. A cylindrical guide sphere 501 inserted into the space portion 101 and having a space portion 101 opened therein, a guide cover 502 for shielding the open upper portion of the guide sphere 501, and a guide sphere. 501 and the guide cover 502 is composed of a coupling nut 503 for fixing in the valve body 100.

At this time, the guide sphere 501 is seated on the guide fitting seating jaw 107 formed at a position spaced apart a predetermined distance upward from the bottom in the space portion 101 of the valve body 100, the bottom of the guide sphere 501 Piston through holes 501b and 501c through which the first and second pistons 201 and 301 pass are formed, respectively.

In addition, an insertion part 502a is formed at the lower edge of the guide cover 502 to be inserted into the space portion 101 of the guide tool 501, and a first piston through which the upper part of the first piston 201 penetrates. A falling rod through hole 204b through which the through hole 502b and the falling rod 303 pass is formed.

The coupling nut 503 is screwed to the upper end of the valve body 100 while the guide cover 502 is wrapped around the upper end thereof, whereby the guide sphere 501 and the guide cover 502 are spaced parts of the valve body 100. It is fixed in 101.

An opening hole 503a is formed at the upper end of the coupling nut 503, and a washer seating jaw 503d is formed at the edge of the opening hole 503a to which the washer 204 of the first discharge hole switch 200 is seated. do.

As shown in Figures 2 to 4, the connector 600 is connected to the valve body 100 and the draft tower 2, one end is connected to the inlet hole 102 and the other end is a draft tower ( 2) the connection pipe 601 connected to, the plug 602 installed in the connection pipe 601 to adjust the flow rate of draft beer, coupling nut for fixing one end of the connection pipe 601 to the valve body 100 ( 603 and a flow rate adjustment bolt 604 for adjusting the position of the draft beer by adjusting the position of the plug 602.

At this time, one end of the plug 602 is inserted into the inlet hole 102 in the form of a fallopian tube and the other end is inserted into the front opening side of the connecting pipe 601, the diameter of one end of the plug 602 is the inlet hole ( 102) is smaller than the inlet side diameter.

Therefore, when the draft beer is introduced through the connecting pipe 601, the plug 602 is pushed by the draft beer to block the inlet hole 102, but the flow rate adjustment bolt penetrates diagonally from the outside of the inlet hole 102. By pushing one end of the plug 602 with 604, a gap is formed between the plug 602 and the inlet hole 102, and draft beer flows through the gap.

That is, if the flow control bolt 604 is tightened a lot, the plug 602 is pushed more and the gap between the plug 602 and the inlet hole 102 is increased, thereby increasing the flow rate and conversely, tightening the flow control bolt 604 less. Since the main surface plug 602 is pushed less, the clearance between the plug 602 and the inlet hole 102 becomes small, so that the inflow amount becomes small.

On the other hand, the front opening side of the connection pipe 601 is inserted into the inlet hole 102, the insertion portion 601b is formed on the connection pipe seating jaw 108 formed in the inlet hole 102, the front opening side outside A locking jaw 601a is formed on the locking jaw 603a formed at one end of the coupling nut 603.

Accordingly, the coupling nut 603 is screwed to the outside of the inlet hole 102 side of the valve body 100 while the other end of the coupling tube 601 is passed through the coupling nut 603. The valve body 100 is connected.

Hereinafter will be described in detail the process of drawing the draft beer and bubbles through the draft beer withdrawal device according to an embodiment of the present invention configured as described above.

After the draft beer in the draft beer flows into the space 101 of the valve body 100 along the flow path formed in the supply pipe, the connection pipe 601, the valve body 100 of the draft tower (2), It is discharged through the first and second discharge holes 103 and 104. At this time, the draft beer discharged through the second discharge hole 104 is converted into a bubble is discharged.

Referring to FIG. 7, a process of discharging draft beer through the first discharge hole 103 will be described first.

First, when the vertically standing lever 202 is tilted forward, the first piston 201 rises and the shielding member 208 that is shielding the first discharge hole 103 rises together with the first piston 201. As it is separated from the first discharge hole 103, the draft beer flowing into the space 101 is discharged to the outside through the first discharge hole 103.

As the first piston 201 rises, the tension spring contact plate 210 interposed on the outside of the first piston 201 in the guide hole 501 of the actuator guide 500 also rises at the same time. ) And the tension spring 209 interposed between the tension spring contact plate 210 is compressed.

Accordingly, when the hand is released from the lever 202 which is inclined forward after discharging the draft beer through the first discharge hole 103, the tension spring contact plate 210 is lowered by the restoring force of the tension spring 209, and at the same time, the first As the piston 201 descends, the shielding member 208 fixed to the lower end of the first piston 201 shields the first discharge hole 103 and the discharge of the draft beer is stopped. The lever 202 also returns to its original state, that is, the vertical state, when the first piston 201 is lowered.

Referring to FIG. 8, a process of generating bubbles while passing draft beer through the second discharge hole 104 and passing through the bubble generator 400 will be described.

When the lever 202 is in a vertical state, when the push button 304 of the second discharge hole actuator 300 installed in the lever 202 is pressed and lowered, the pusher 302 is lowered and the lowering rod 303 is pressed. When the second piston 301 is lowered by the lowering rod 303, the neck hole shielding portion 301a that is shielding the neck hole 106 of the second discharge hole 104 descends and the neck hole shielding portion 301a. The neck portion 301b formed at the top of the neck hole 106 is located.

At this time, since the diameter of the neck portion 301b is smaller than the inner diameter of the neck hole 106, draft beer flowing into the space portion 101 of the valve body 100 is formed through a gap between the neck portion 301b and the neck hole 106. 2 is discharged to the discharge hole 104.

Draft beer discharged into the second discharge hole 104 is introduced into the spray tube 402 of the bubble generator 400 and passes through the fine holes 401a of the spray plate 401 formed in the spray tube 402. Sprayed in a state.

The draft beer sprayed in such a fine particle state passes through the expansion hole 403a of the expansion plate 403 located below the spray tube 402 to generate bubbles. That is, when the draft beer passes through the fine holes 401a, the pressure is increased and compressed, and when the draft beer passes through the expansion hole 403a, the pressure is reduced to expand and thereby bubbles are generated.

As such, since the draft beer particles passing through the fine holes 401a of uniform diameter are constant and fine, the particles are constant and small even when expanded while passing through the expansion holes 403a. Therefore, bubbles generated while passing through the expansion hole 403a also have small and fine particles.

Bubbles generated while passing through the expansion plate 403 are discharged to the outside through the bubble guide hole 410a.

Meanwhile, when the push button 304 is pressed down, the second piston 301 descends and the spring 308 interposed on the upper portion of the second piston 301 in the guide port 501 of the actuator guide 500 is provided. It is pushed downward by the spring contact hole 309 mounted on the upper portion of the second piston 301 is compressed.

Accordingly, when the user releases the push button 304, the push button 304 returns to its original state while the push button 304 returns to its original state by the restoring force of the spring 306 that was elastically supporting the push button 304. Then, since the force for lowering the second piston 301 is released, the spring contact hole 309 is raised by the restoring force of the spring 308 that has been compressed by the spring contact hole 309, and the second piston 301 is also raised. Done.

As a result, the neck hole shielding portion 301a formed at the lower end of the second piston 301 is also raised to shield the neck hole 106, so that the draft beer is discharged through the second discharge hole 104 is stopped.

On the other hand, the flow rate flowing into the valve body 100 through the connector 600 is adjusted by the flow rate adjustment bolt 604 of the connector (600). That is, if the flow control bolt 604 is tightened a lot, the plug 602 is pushed more and the gap between the plug 602 and the inlet hole 102 is increased, thereby increasing the flow rate and conversely, tightening the flow control bolt 604 less. Since the main surface plug 602 is pushed less, the clearance between the plug 602 and the inlet hole 102 becomes small, so that the inflow amount becomes small.

As described above with reference to the accompanying drawings, draft beer drawing device according to a preferred embodiment of the present invention, the present invention is not limited to the embodiments and drawings described in detail herein, various within the technical scope of the invention Modifications can be made.

According to the present invention draft beer extracting device configured as described above, by allowing the foam to be produced and discharged through the passage and the separate passage through which the draft beer is discharged to selectively follow the foam, it is possible to meet the various needs of the guests.

In addition, since the draft beer particles passing through the fine holes of uniform diameter are constant and fine, the particles are constant and small even if they are expanded while passing through the expansion holes. Therefore, the foam generated while passing through the expansion hole also has a small and fine characteristic. In this way, the bubbles of the resulting bubbles are small and multiply, so that the foam can be maintained for a long time, thereby suppressing the evaporation of the ingredients that give the draft beer the natural flavor can be maintained for a long time the natural taste of the raw.
