DETAILED DESCRIPTION

Specific implementations of the disclosure herein will further be described below in detail in combination with the drawings and embodiments. The following embodiments are used to describe the disclosure herein rather than limit the scope of the disclosure herein.

As shown in FIGS. 1 to 8, a distributor includes a keg head 1, a valve element 2, an elastic member 3, and a valve element switch 4 configured to control the valve element 2 to act. The keg head 1 is provided with a liquid inlet 101 in fluid communication with a beer keg, a liquid outlet 102 configured for liquid to flow out, and a valve element mounting hole 103 matched with the valve element 2. The liquid inlet 101 and the liquid outlet 102 are communicated with the valve element mounting hole 103 respectively to implement the communication of the liquid inlet 101 and the liquid outlet 102 through the valve element mounting hole 103. The valve element 2 includes a control portion 201 movably mounted in the valve element mounting hole 103 to control the communication or disconnection between the liquid inlet 101 and the liquid outlet 102 and a switch connecting portion 202 configured to be connected to the valve element switch 4.

The valve element 2 is provided with a first matching body 203. The valve element switch 4 is provided with a second matching body 401 matched with the first matching body 203. The elastic member 3 acts on the valve element 2 such that the first matching body 203 tends to move to abut against the second matching body 401.

With the adoption of the above-mentioned structure, the valve element switch 4 is operated to control a position of the valve element 2 in the valve element mounting hole 103 to implement the communication and disconnection between the liquid inlet 101 and the liquid outlet 102. When the liquid inlet 101 is communicated with the liquid outlet 102, liquid enters the keg head 1 from the liquid inlet 101 and flows out of the liquid outlet 102 through the valve element mounting hole 103.

In the above-mentioned structure, the floating connection between the valve element switch 4 and the valve element 2 is implemented through the first matching body 203, the second matching body 401 and the elastic member 3. The elastic member 3 causes the first matching body 203 to tend to move to abut against the second matching body 401, namely the first matching body 203 may always move to abut against the second matching body 401. Therefore, the connection between the valve element switch 4 and the valve element 2 is implemented, namely the valve element switch 4 may control the valve element 2.

If the valve element switch 4 is directly in rigid connection to the valve element 2, namely the valve element 2 and the valve element switch 4 act completely synchronously, the valve element 2 is inclined when the valve element switch 4 is slightly inclined during adjustment, and in such case, the valve element 2 and the valve element mounting hole 103 are easily locked. Compared with the rigid connection between the valve element switch 4 and the valve element 2, the floating connection between the valve element switch 4 and the valve element 2 may effectively eliminate the locking phenomenon. Since the valve element 2 is in movable floating connection to the valve element switch 4, the valve element 2 may be movably adjusted along a direction of the valve element mounting hole 103 under the adjustment of the valve element switch 4 when the valve element switch 4 is slightly inclined during adjustment. However, the valve element mounting hole 103 may limit the valve element 2 to prevent the valve element 2 from being inclined with the valve element switch 4 and further avoid the phenomenon that the valve element 2 is locked.

Preferably, the valve element switch 4 is provided with a mounting through hole 402. The switch connecting portion 202 extends into the mounting through hole 402 from an opening in one end of the mounting through hole 402. A side wall of the switch connecting portion 202 protrudes to an inner wall side of the mounting through hole 402 to form the first matching body 203. An inner wall of the mounting through hole 402 protrudes to an outer wall side of the switch connecting portion 202 to form the second matching body 401. The second matching body 401 is located between the first matching body 203 and the control portion 201. An elastic member limiter 403 is disposed in an opening in the other end of the mounting through hole 402. Two ends of the elastic member 3 are pressed against the valve element 2 and the elastic member limiter 403 respectively such that the elastic member 3 is deformed by axial pressure.

With the adoption of the above-mentioned structure, when an adjustment direction of the valve switch is a direction that the valve element 2 is separated from the valve element mounting hole 103, the second matching body 401 on the valve switch applies a force to the first matching body 203 on the valve element 2 such that the valve element 2 moves to the direction of separating from the valve element mounting hole 103. When the adjustment direction of the valve element switch 4 is a direction that the valve element 2 extends into the valve element mounting hole 103, the second matching body 401 on the valve switch moves to the direction of extending into the valve element mounting hole 103 and is separated from the first matching body 203. However, the elastic member 3 is deformed by the axial pressure and thus may apply a force to the valve element 2 to cause the valve element 2 to move to the side of extending into the valve element mounting hole 103 until the first matching body 203 abuts against the second matching body 401 again. The movement of the valve element 2 implements the communication or disconnection between the liquid inlet 101 and the liquid outlet 102.

The elastic member 3 is a spring, and an end thereof acting on the valve element 2 specifically acts on the first matching body 203 protruding from the valve element 2.

The elastic member limiter 403 is an end cover matched with the mounting through hole 402.

Preferably, a mounting opening of the valve element 2 penetrating through the keg head 1 is formed in one end of the valve element mounting hole 103. The valve element switch 4 is in threaded connection to the end, where the mounting opening of the valve element 2 is disposed, of the keg head 1. The valve element switch 4 implements the movable adjustment of the valve element 2 linked with the valve element switch 4 in the valve element mounting hole 103 by thread adjustment with the keg head 1.

With the adoption of the above-mentioned structure, an operator may control the valve element 2 only by rotating the valve element switch 4, so the simplicity and convenience for operation are ensured.

As shown in FIG. 3, preferably, the valve element switch 4 includes a thread fitting portion 404 extending into the valve element mounting hole 103, a switch matching portion 405 outside the keg head 1, and a switch transition portion 406 configured to connect the thread fitting portion 404 with the switch matching portion 405. A thread is disposed on an outer wall of the thread fitting portion 404. A thread matched with the thread of the thread fitting portion 404 is disposed on an inner wall of the valve element mounting hole 103 close to the side of the mounting opening of the valve element 2.

The switch matching portion 405 is provided with a limiting member 407 protruding to an outer wall side of the keg head 1. An outer wall of the keg head 1 protrudes to the side of the switch matching portion 405 to form a limiting portion 105. The limiting portion 105 is located between the limiting member 407 and the switch transition portion 406.

With the adoption of the above-mentioned structure, when the adjustment direction of the valve element switch 4 is a direction that the valve element 2 is separated from the valve element mounting hole 103, the limiting member 407 on the valve element switch 4 may gradually get close to until abutting against the limiting portion 105 of the keg head 1. In a state that the limiting member 407 abuts against the limiting portion 105, the limiting portion 105 limits the limiting member, namely limits the valve element switch 4, such that the valve element switch 4 cannot continue to be adjusted to the direction, and it indicates that the valve element switch 4 has been maximally adjusted to this side.

Specifically, the limiting member adopts a set screw. The set screw penetrates through the switch matching portion 405, and one end is beyond a side of the switch matching portion 405 facing an outer wall of the keg head.

Preferably, at least an end of the control portion 201 away from the switch control portion 201 presents a gradually enlarged tapered structure 2011 along a direction of getting close to the switch connecting portion 202. A matched taper hole is disposed at a position, configured to accommodate the tapered structure 2011 of the control portion 201, of the valve element mounting hole 103.

With the adoption of the above-mentioned structure, when the valve element 2 moves to the side of separating from the valve element mounting hole 103, a gap may be formed between the tapered structure 2011 of the control portion 201 and the taper hole of the valve element mounting hole 103, the liquid inlet 101 is communicated with the liquid outlet 102 through the gap, and positions of the tapered structure 2011 and the taper hole may be adjusted to adjust the size of the gap therebetween, thereby adjusting the flow. When the valve element 2 moves to the side of extending into the valve element mounting hole 103 until the tapered structure 2011 completely fits the taper hole, the liquid inlet 101 cannot be communicated with the liquid outlet 102 through the valve element mounting hole 103.

Specifically, the liquid inlet 101 is provided in a bottom end of the keg head 1. The liquid outlet 102 is provided in a side edge of the keg head 1. The valve element mounting hole 103 is provided in a top end of the keg head 1. The valve element 2 moves up and down in the valve element mounting hole 103 to implement the communication and disconnection of the liquid inlet 101 and the liquid outlet 102.

Preferably, the switch connecting portion 202 is clamped with the control portion 201. A first end face 2022 of the switch connecting portion 202 facing the control portion 201 is sunken to form a clamping groove 2021. A second end face 2013 of the control portion 201 facing the switch connecting portion 202 protrudes to form a clamping protruding block 2012 matched with the clamping groove 2021. The first matching body 203 is disposed on the switch connecting portion 202.

With the adoption of the above-mentioned structure, when being assembled, the valve element switch 4 and the valve element 2 are fixed by the clamping protruding block 2012 and the clamping groove 2021 by arranging the switch connecting portion 202 at first in the mounting through hole 402 such that the first matching body 203 is located on one side of the second matching body 401 and arranging the control portion 201 on the other side of the second matching body 401.

Preferably, an edge of a second end face 2013 of the control portion 201 facing the switch connecting portion 202 is beyond that of a first end face 2022 of the switch connecting portion 202 facing the control portion 201. The second end face 2013 forms a second matching body accommodation groove 204 with a third end face 2031 of the first matching body 203 facing the second end face 2013. An end face of the second matching body 401 facing the second end face 2013 forms a fourth end face 4011. An end face of the second matching body 401 facing the third end face 2031 forms a fifth end face 4012. A distance from the second end face 2013 to the third end face 2031 is greater than that from the fourth end face 4011 to the fifth end face 4012.

With the adoption of the above-mentioned structure, a thickness of the second matching body 401 is smaller than a width of the second matching body accommodation groove 204. That is, the inclination of the second matching body may be adjusted in an accommodation cavity of the second matching body 401 to prevent the valve element 2 from being inclined in the valve element mounting hole 103.

Preferably, the distributor includes a distributor seat 5 and an operating device 6. The distributor seat 5 is provided with a keg head sleeve-connection hole 501 in movable matched sleeve connection to the keg head 1. The operating device 6 is in matched connection to the distributor seat 5 and the keg head 1 respectively. The keg head 1 is driven by the operating device 6 to slide in the keg head sleeve-connection hole 501 to open and close a corresponding keg spear 7.

The keg spear 7 is mounted to a beer outlet 701 of the beer keg. With the adoption of the above-mentioned structure, the distributor is mounted to the keg spear 7. If intended to open the keg spear 7, a user needs to operate the operating device 6 to drive the keg head 1 to open the keg spear 7 and adjust the valve element switch 4 to communicate the liquid inlet 101 with the liquid outlet 102. If intended to close the keg spear 7, the user needs to reversely operate the operating device 6 to drive the keg head 1 to close the keg spear 7.

As shown in FIG. 8, generally, the keg spear 7 is provided with a beer outlet passage 702 and the beer outlet 701 is formed in the keg spear 7. A bore diameter of the beer outlet 701 is smaller than the beer outlet passage 702. A plug 703 configured to plug the beer outlet 701 and a plug reset member 704 acting on the plug 703 such that the plug moves to a side of plugging the beer outlet 701 are movably disposed in the beer outlet passage 702. When the keg head 1 moves to a side close to the plug 703, the keg head 1 drives the plug 703 to overcome an acting force of the plug reset member 704 to move to a side away from the beer outlet 701 to open the beer outlet 701. When the keg head 1 moves to a side away from the plug 703, the plug 703 moves to a side close to the beer outlet 701 under the action of the plug reset member 704 to plug the beer outlet 701.

Preferably, the operating device 6 includes a driving arm 601 and a handle 602. One end of the driving arm 601 is in matched hinged connection to the distributor seat 5, while the other end is in matched connection to the handle 602. A driving block 6011 is disposed on an inner side wall of the driving arm 601 facing the keg head 1. A driving sliding chute 106 matched with the driving block 6011 is disposed in a side wall of the keg head 1 facing the driving arm 601.

With the adoption of the above-mentioned structure, the operator acts on the handle to drive the driving arm 601 to rotate, and the driving block 6011 slides in the driving sliding chute 106. The driving block 6011 circumferentially moves with the rotation of the driving arm 601 and thus may apply an acting force to a side wall of the driving sliding chute 106 to slide the keg head 1 in the keg head sleeve-connection hole 501 of keg head 1. A support rod 506 configured to be hinged to the driving arm 601 protrudes from the distributor seat 5.

Specifically, there are two driving arms 601 located on two sides of the keg head 1 respectively. Ends, not hinged to the distributor seat 5, of the two driving arms 601 are connected by a driving arm connecting belt 603. The handle is disposed on the driving arm connecting belt 603.

As shown in FIG. 6, preferably, the handle 602 includes a fixed handle 6021, a movable handle 6022, an ejector rod 6023, and an ejector rod reset member 6024. The fixed handle 6021 is connected to the driving arm 601. The fixed handle 6021 is provided with an ejector rod ferrule hole 6021a for sliding of the ejector rod 6023. At least one end of the ejector rod ferrule hole 6021a penetrates through the fixed handle 6021 to expose an ejector head 6023a of the ejector rod 6023. A surface of a vertically distributed stopping plate 502 is provided at a position of the distributor seat 5 close to the ejector head 6023a. At least a first stopping slot 5021 and second stopping slot 5022 which are matched with the ejector head 6023a are provided on a side of the stopping plate 502 facing the ejector head 6023a.

The movable handle 6022 is connected to the ejector rod 6023 to drive the ejector head 6023a of the ejector rod 6023 to get close to or away from the stopping plate 502. The ejector rod reset member 6024 acts on the ejector rod 6023 such that the ejector rod 6023 tends to move to the side of the stopping plate 502.

The operating device 6 drives the keg head 1 to close the keg spear 7 when the ejector head 6023a of the ejector rod 6023 is in the first stopping slot 5021.

The operating device 6 drives the keg head 1 to open the keg spear 7 when the ejector head 6023a of the ejector rod 6023 is in the second stopping slot 5022.

With the adoption of the above-mentioned structure, the first stopping slot 5021 and the second stopping slot 5022 are matched with the ejector head 6023a of the ejector rod 6023 to lock the operating device 6, namely lock the keg head 1.

If intended to switch a state of the operating device 6, namely switch a state of the keg head 1, the operator needs to operate the movable handle at first to drive the ejector rod 6023 to overcome an acting force of the ejector rod reset member 6024 such that the ejector head 6023a moves to a side away from the stopping plate 502 until the ejector head 6023a is separated from the first stopping slot 5021 or the second stopping slot 5022. In such case, the operating device 6 is unlocked, and the operator may operate the operating device 6 to drive the keg head 1. After the operation, the movable handle is released, and the ejector rod 6023 moves to a side close to the stopping plate 502 under the action of an acting force of the ejector rod reset member 6024 until the ejector head 6023a reenters the first stopping slot 5021 or the second stopping slot 5022 to re-lock the operating device 6.

Preferably, the movable handle 6022 is provided with a handle ferrule hole 6022a. The movable handle 6022 is in sleeve connection outside the fixed handle 6021 by the handle ferrule hole 6022a.

Specifically, the ejector rod ferrule hole 6021a includes a first ejector rod ferrule hole 6021a1 with a large bore diameter and a second ejector rod ferrule hole 6021a2 with a small bore diameter. The ejector rod 6023 includes the ejector head 6023a, a large cylindrical section matched with the first ejector rod ferrule hole 6021a1 and a small cylindrical section 6023c matched with the second ejector rod ferrule hole 6021a2, which are coaxially connected into a whole in sequence. A snap spring slot 6023c1 is disposed in a tail end of the small cylindrical section 6023c. After the ejector rod 6023 penetrates through the ejector rod ferrule hole 6021a, tail ends of the snap spring slot 6023c1 and the fixed handle 6021 are sleeved with a gasket 6026 and limited by a snap spring 6025 clamped into the snap spring slot 6023c1. An external diameter of the gasket 6026 is larger than that of the fixed handle 6021. The ejector rod reset member 6024 is located between a bottom end of the first ejector rod ferrule hole 6021a1 and the large cylindrical section 6023b and in matched sleeve connection to the small cylindrical section 6023c. The handle ferrule hole 6022a includes a first handle ferrule hole 6022a1 matched with the external diameter of the fixed handle 6021 and a second handle ferrule hole 6022a2 of which a bore diameter is larger than that of the first handle ferrule hole 6022a1. The bore diameter of the second handle ferrule hole 6022a2 is matched with the external diameter of the gasket 6026.

With the adoption of the above-mentioned structure, when the operator pulls the movable handle 6022 to the side away from the stopping plate 502, since the bore diameter of the second handle ferrule hole 6022a2 is larger than that of the first handle ferrule hole 6022a1, a step surface is formed to apply an acting force to the gasket 6026 to cause the ejector rod 6023 to overcome an acting force of the ejector rod reset member 6024 to move to the side away from the stopping plate 502. After the operator releases the movable handle 6022, the ejector rod reset member 6024 acts on the large cylindrical section 6023b such that the ejector rod 6023 moves to the side close to the stopping plate 502. The ejector rod 6023 stops moving when the gasket 6026 contacts with the tail end of the fixed handle 6021.

Preferably, an end face at an opening of the handle ferrule hole 6022a circumferentially protrudes to form a first cambered bump 6022b, and is circumferentially sunken to form a first cambered recess 6022c. The first cambered bump 6022b is connected to the first cambered recess 6022c with a smooth transition formed at a junction. The fixed handle 6021 protrudes at the opening of the handle ferrule hole 6022a to form a matching surface 6021b contacting with the end face at the opening of the handle. The matching surface 6021b circumferentially protrudes to form a second cambered bump 6021b1 matched with the first cambered recess 6022c, and is circumferentially sunken to form a second cambered recess 6021b2 matched with the first cambered bump 6022b.

With the adoption of the above-mentioned structure, the operator only needs to rotate the movable handle 6022 such that a peak of the first cambered bump 6022b slides to be opposite to that of the second cambered bump 6021b1, and the movable handle 6022 may naturally slide along the fixed handle 6021 and drive the ejector rod 6023 to overcome the acting force of the ejector rod reset member 6024 to move. After the operator releases the movable handle 6022, the ejector rod 6023 is reset under the acting force of the ejector rod reset member 6024 and drives the movable handle 6022 to rotate such that the peak of the first cambered bump 6022b slides to be opposite to a trough of the second cambered recess 6021b2 and slides along a direction opposite to the fixed handle 6021. The above-mentioned operating manner is more labor-saving.

As shown in FIGS. 2 and 8, preferably, a cambered buckling plate 503 is disposed at a bottom end of the distributor seat 5. The cambered buckling plate 503 is provided with a cambered buckling groove 5031 horizontally matched and buckled with an annular step 705 on a side edge of a top surface of the keg spear 7. The distributor seat 5 is provided with an inserted pin 504 at a position where the cambered buckling plate 503 is not disposed. The inserted pin 504 is slidably mounted to the distributor seat 5. An extending surface of a cambered surface of the cambered buckling groove 5031 is tangent to a lateral surface of the inserted pin 504. The distributor seat 5 is provided with an inserted pin seat 505 at a position where the inserted pin 504 is disposed.

With the adoption of the above-mentioned structure, the operator operates the inserted pin 504 to make a bottom surface thereof not beyond that of the distributor seat 5, then causes the bottom end of the distributor seat 5 to abut against the top surface of the keg spear 7, and slides the distributor seat 5 to clamp the annular step 705 on the keg spear 7 into the cambered buckling groove 5031. The inserted pin 504 is operated to make the bottom surface thereof beyond that of the distributor seat 5 and the lateral surface thereof tangent to the annular step 705 of the keg spear 7, to implement the connection between the distributor and the keg spear 7. By the above-mentioned structure, the distributor may further rotate 360 degrees on the keg spear 7 to adjust the position of the liquid outlet 102. If the distributor needs to be separated from the keg spear 7, it is only necessary to operate the inserted pin 504 again to make the bottom surface thereof not beyond the bottom end of the distributor seat 5 and slide the distributor seat 5 to separate the annular step 705 on the keg spear 7 from the cambered buckling groove 5031, to separate the distributor seat 5 from the keg spear 7.

Preferably, a bottom surface of the keg head 1 is beyond that of the distributor seat 5 when the ejector head 6023a of the ejector rod 6023 is in the first stopping slot 5021 or the second stopping slot 5022. A third stopping slot 5023 is further provided on a side of the stopping plate 502 facing the ejector head 6023a. The bottom surface of the keg head 1 is not beyond that of the distributor seat 5 when the ejector head 6023a of the ejector rod 6023 is in the third stopping slot 5023.

With the adoption of the above-mentioned structure, the bottom surface of the keg head 1 is not beyond that of the distributor seat 5 when the operator operates the movable handle to locate the ejector head 6023a in the third stopping slot 5023. In such case, when the distributor seat 5 is mounted to the keg spear 7 or dismounted from the keg spear 7, the influence of the keg head 1 on the above-mentioned process is avoided.

The above is only the preferred implementations of the disclosure herein. It is to be pointed out that those of ordinary skill in the art may further make a plurality of improvements and embellishments without departing from the technical principle of the disclosure herein, and these improvements and embellishments should also fall within the scope of protection of the disclosure herein.
