Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of beverage container, and relates to a dispenser. BACKGROUND

[0002] The beverage barrel is a tool for containing wine and beverage, and a wine spear is arranged at the barrel opening of the beverage barrel, a valve core is arranged in the wine spear, and the valve core can control the gas-liquid flow state between the inside and outside of the barrel body. The dispenser is often connected to the top of the barrel body and cooperates with the wine spear, and is in a closed state under normal circumstances. When liquid needs to be discharged, the user presses the handle on the dispenser downward, so that the liquid guide pipe moves downward and pushes open the valve core on the wine spear, the valve core allows the gas-liquid flow between the inside and outside of the barrel body, at the same time, the external gas enters the valve hole of the dispenser, and then enters the barrel body through the wine spear, so as to press the liquid in the barrel body out.

[0003] However, the existing dispenser often needs to open a pressure relief hole for communicating the gas passage on the valve body, and a pressure relief valve is arranged in the pressure relief hole, so as to release the gas remaining in the gas passage. This design makes the structure more complex and the cost higher.

[0004] Therefore, the Chinese patent application (application number: 202321238740.X) discloses a dispenser, which comprises a valve body and a wine guide pipe, a guide hole, an air inlet hole and an air cavity communicated with the guide hole are arranged in the valve body, a sealing ring is arranged on the inner wall of the guide hole, the outer periphery of the wine guide pipe has a sealing part capable of forming a seal with the inner wall of the guide hole through the sealing ring, characterized in that the outer periphery of the wine guide pipe is further provided with an air passage groove and a sliding part, the sealing part is located above the air passage groove, the sliding part is located below the air passage groove, the sliding part is in sliding cooperation with the inner wall of the guide hole and a gas discharge gap communicated with the air passage groove is formed between the sliding part and the inner wall of the guide hole, and a valve core for controlling the opening and closing of the air inlet hole is arranged in the air inlet hole; when the dispenser is in a closed state, the valve core blocks the air inlet hole, the position of the air passage groove is opposite to the sealing ring and is communicated with the outside, and the sealing part and the inner wall of the guide hole are not sealed.

[0005] However, the above method has the following defects: 1. When the beverage barrel needs to be replaced, in order to avoid leakage and waste, the user needs to close the dispenser, the valve core blocks the air inlet hole, the sealing part and the inner wall of the guide hole form a closed state, and then the dispenser is transferred to a new beverage barrel, so that the use of the dispenser is troublesome. 2. If the dispenser is not operated properly when it is installed on the top of the barrel body, the dispenser and the wine spear cannot be stably installed and cooperated, at this time, the external gas cannot smoothly enter the inner cavity of the barrel body through the dispenser and the wine spear, and there is a leakage problem. UTILITY MODEL CONTENTS

[0006] The utility model discloses a kind of dispensers for the above problems existing in prior art, and the technical problems to be solved by the utility model are: how to avoid leakage problem caused by unstable installation on the basis of ensuring that dispenser is convenient to use.

[0007] The utility model discloses a kind of dispensers, including valve body and liquid guide pipe, the valve body is equipped with air chamber, air inlet and valve hole one, the valve hole one is communicated with air inlet, the liquid guide pipe is sequentially inserted valve hole one and air chamber, it is characterized in that, the inner side wall of valve hole one both ends respectively with liquid guide pipe outer side wall sealing cooperation, the valve body is also equipped with valve hole two, first through-hole and second through-hole, the both ends of first through-hole are respectively communicated with air chamber and valve hole two, the both ends of second through-hole are respectively communicated with valve hole one and valve hole two, valve rod is equipped in valve hole two, the valve rod can be extended valve hole two downwards and make first through-hole and second through-hole cut off, this valve rod can also be moved upwards and make first through-hole and second through-hole conduct.

[0008] Under normal circumstances, valve rod lower end extends valve hole two.When installing, valve body is connected with matching wine lance, wine lance is resisted to valve rod bottom end, valve rod is moved upwards by being pushed, after installation, valve rod makes first through-hole and second through-hole conduct, gas in cylinder is sequentially passed through air inlet, valve hole one, second through-hole, valve hole two, first through-hole and air chamber, and then enters barrel inner cavity through wine lance.Drinks barrel needs to be replaced, valve body is detached from wine lance, valve rod resets, extends valve hole two downwards and makes first through-hole and second through-hole cut off, without specially closing dispenser, valve body can be quickly installed on the wine lance of another barrel, without gas leakage problem, convenient to use.When dispenser is installed in place, valve rod is only moved upwards to the position that makes first through-hole and second through-hole conduct, otherwise, first through-hole and second through-hole are in cut-off state, so that gas is enclosed in dispenser, even if dispenser handle is pressed, there is no leakage problem.Valve rod controls the conduction and cut-off of first through-hole and second through-hole to manage gas flow state, not only makes gas flow path more clear, but also provides double protection for sealing property.

[0009] The above-mentioned dispenser, the valve hole two is also equipped with spring, the both ends of the spring are respectively resisted with valve hole two inner side wall and valve rod upper end.When installing, valve rod is moved upwards by being pushed by wine lance, spring is compressed, when disassembling, spring pushes valve rod to reset and move downwards.Valve rod resets under the joint action of its gravity and spring, spring not only provides sufficient pressure, but also can effectively absorb vibration, so that valve rod movement is stable.

[0010] The valve rod comprises a rod body and an adjusting nut arranged at the upper end of the rod body, the spring is sleeved on the rod part of the adjusting nut, and the spring abuts against the head part of the adjusting nut. The spring is sleeved on the rod part of the adjusting nut, which can effectively avoid the spring from shaking or mispositioning during work, the spring is constrained in the circumferential direction, and the correct working posture can be ensured, so that the movement of the valve rod is stable and reliable. When the spring abuts against the head part of the adjusting nut, the adjusting nut can be replaced when it is worn, instead of replacing the whole valve rod, so that the maintenance cost is greatly reduced.

[0011] The valve hole two has a large upper end and a small lower end, and the lower end has a smaller diameter than the head part of the adjusting nut. The large upper end of the valve hole two leaves sufficient space for the deformation of the spring, and the small lower end effectively limits the circumferential shaking of the valve rod during movement. In addition, since the lower end of the valve hole two has a smaller diameter than the head part of the adjusting nut, the valve rod is limited by the lower end of the valve hole two when it moves downward, thereby avoiding the valve rod from completely falling out of the valve hole two, and making the movement of the valve rod stable.

[0012] The higher end of the first through hole is inclined toward the valve hole two, and the lower end is inclined toward the air chamber, and the higher end of the second through hole is inclined toward the valve hole one, and the lower end is inclined toward the valve hole two. The inclined arrangement of the first through hole and the second through hole helps the smooth flow of gas into the through hole, and prevents the gas from flowing backward or stagnating when flowing out. In addition, by adjusting the inclination angle, the overall design of the dispenser can be more compact and reasonable, and unnecessary space waste can be reduced.

[0013] The inner side walls of the two ends of the valve hole one are respectively protruded inward to form annular protrusions, and the annular protrusions are in sealing cooperation with the liquid guide pipe. Compared with point contact sealing, the annular protrusions provide a large-area sealing contact surface, which not only has better sealing effect, but also has more uniform contact pressure, and can effectively disperse the sealing stress.

[0014] The annular protrusions are provided with annular grooves, and the annular grooves are provided with sealing rings. The annular grooves prevent the displacement of the sealing rings during use, and the sealing rings and the inner circumferential surface of the annular protrusions cooperate to achieve sealing, which makes the work stable and reliable and improves the sealing effect.

[0015] Compared with the prior art, the dispenser has the following advantages:

[0016] 1. When the beverage barrel needs to be replaced, the valve body is detached from the wine spear, the valve rod is reset, the valve hole two is extended downward, and the first through hole and the second through hole are cut off. Without the need to intentionally close the dispenser, the valve body can be quickly installed on the wine spear of another barrel body, and there is no gas leakage problem, which is convenient to use.

[0017] 2、The distributor, the valve rod is moved up to the position of the first through hole and the second through hole are in the open state, otherwise, the first through hole and the second through hole are in the closed state, so that the gas is closed in the distributor, even if the distributor handle is pressed, there will be no leakage problem.

[0018] 3、The distributor, the valve rod is moved up to the position of the first through hole and the second through hole are in the open state, otherwise, the first through hole and the second through hole are in the closed state, so that the gas is closed in the distributor, even if the distributor handle is pressed, there will be no leakage problem.

DETAILED DESCRIPTION

[0025] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the distributor comprises a valve body 1 and a liquid guide pipe 2, the valve body 1 is provided with an air chamber 3, an air inlet 4 and a valve hole one 5, the valve hole one 5 is communicated with the air inlet 4, the liquid guide pipe 2 extends into the valve hole one 5 and the air chamber 3 in sequence, the inner side wall of both ends of the valve hole one 5 is respectively sealed with the outer side wall of the liquid guide pipe 2.

[0028] Specifically, the inner side wall of both ends of the valve hole one 5 is respectively protruded inward to form a ring-shaped convex edge 5a, the ring-shaped convex edge 5a is sealed with the liquid guide pipe 2. Compared with point contact sealing, the ring-shaped convex edge 5a provides a large area of sealing contact surface, not only the sealing effect is better, but also the contact pressure is more uniform, which can effectively disperse the sealing stress.

[0029] The ring-shaped convex edge 5a is provided with a ring-shaped groove 5a1, and a sealing ring 11 is arranged in the ring-shaped groove 5a1. The ring-shaped groove 5a1 prevents the displacement of the sealing ring 11 during use, and the sealing ring 11 cooperates with the inner circumferential surface of the ring-shaped convex edge 5a to realize sealing, which stabilizes the work and improves the sealing effect.

[0030] Further, the inner side wall of the valve hole one 5 is provided with a plurality of sealing rings 11.

[0031] The valve body 1 is also provided with a valve hole two 6, a first through hole 7 and a second through hole 8, both ends of the first through hole 7 are respectively communicated with the air chamber 3 and the valve hole two 6, both ends of the second through hole 8 are respectively communicated with the valve hole one 5 and the valve hole two 6. The higher end of the first through hole 7 is inclined to the valve hole two 6 and the lower end is inclined to the air chamber 3, and the higher end of the second through hole 8 is inclined to the valve hole one 5 and the lower end is inclined to the valve hole two 6. The first through hole 7 and the second through hole 8 are inclined to help the gas flow smoothly into the through hole, and to prevent the gas from flowing backward or stagnating when flowing out. In addition, by adjusting the inclination angle, the overall design of the distributor can be more compact and reasonable, reducing unnecessary space waste.

[0032] The valve hole two 6 is provided with a valve rod 9 and a spring 10, the two ends of the spring 10 are respectively abutted with the inner side wall of the valve hole two 6 and the upper end of the valve rod 9, the valve rod 9 can extend out of the valve hole two 6 and cut off the first through hole 7 and the second through hole 8, and the valve rod 9 can also move upward and make the first through hole 7 and the second through hole 8 conductive. When installing, the valve rod 9 is pushed upward by the lance, and the spring 10 is compressed. When disassembling, the spring 10 pushes the valve rod 9 to move downward and reset. The valve rod 9 resets under the joint action of its own gravity and the spring 10, the spring 10 not only provides sufficient pressure, but also effectively absorbs vibration, so that the valve rod 9 moves stably.

[0033] The valve stem 9 comprises a stem body 9a and an adjusting nut 9b arranged at the upper end of the stem body 9a. The spring 10 is sleeved on the stem of the adjusting nut 9b and abuts against the head of the adjusting nut 9b. The spring 10 is sleeved on the stem of the adjusting nut 9b, which can effectively avoid the spring 10 from shaking or mispositioning during work. The spring 10 is constrained in the circumferential direction, which can ensure the correct working posture, so that the movement of the valve stem 9 is stable and reliable. When the spring 10 is worn, the adjusting nut 9b can be replaced, and the valve stem 9 does not need to be replaced as a whole, which greatly reduces the maintenance cost.

[0034] The valve hole two 6 has a large upper end and a small lower end. The lower end of the valve hole two 6 is smaller than the diameter of the head of the adjusting nut 9b. The large upper end of the valve hole two 6 leaves sufficient space for the deformation of the spring 10. The small lower end of the valve hole two 6 effectively limits the circumferential shaking of the valve stem 9 during movement. In addition, since the lower end of the valve hole two 6 is smaller than the diameter of the head of the adjusting nut 9b, the valve stem 9 is limited by the lower end of the valve hole two 6 when it moves downward, which avoids the valve stem 9 from completely falling out of the valve hole two 6, and makes the movement of the valve stem 9 stable.

[0035] Under normal circumstances, the spring 10 is in an elongated state, the lower end of the valve stem 9 protrudes out of the valve hole two 6, and the first through hole 7 and the second through hole 8 are in a cut-off state.

[0036] During installation, the valve body 1 is connected with a matching wine spear, the wine spear abuts against the bottom end of the valve stem 9, the valve stem 9 is pushed upward to move, the spring 10 is compressed, and after installation, the valve stem 9 makes the first through hole 7 and the second through hole 8 conductive. Pressing the handle, the gas in the gas cylinder enters the dispenser, and then enters the inner cavity of the barrel through the gas inlet 4, the valve hole one 5, the second through hole 8, the valve hole two 6, the first through hole 7 and the gas chamber 3.

[0037] When it is necessary to replace the beverage barrel, the valve body 1 is detached from the wine spear, the valve body 1 is reset under the action of its own gravity and the spring 10, the valve body 1 protrudes downward out of the valve hole two 6 and makes the first through hole 7 and the second through hole 8 cut off. Without the need to deliberately close the dispenser, the valve body 1 can be quickly installed on the wine spear of another barrel, and there is no gas leakage problem, which is convenient to use.

[0038] When the dispenser is installed in place, the valve stem 9 is moved upward to a position where the first through hole 7 and the second through hole 8 are conductive. Otherwise, the first through hole 7 and the second through hole 8 are in a cut-off state, so that the gas is sealed in the dispenser. Even if the handle of the dispenser is pressed, there will be no leakage problem. The valve stem 9 controls the conduction and cut-off of the first through hole 7 and the second through hole 8 to manage the gas flow state, which not only makes the gas flow path clearer, but also provides double protection for the sealing performance.

[0039] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0040] Although the valve body 1, the liquid guide pipe 2, the air chamber 3, the air inlet 4, the valve hole one 5, the annular convex edge 5a, the annular groove 5a1, the valve hole two 6, the first through hole 7, the second through hole 8, the valve rod 9, the rod body 9a, the adjusting nut 9b, the spring 10, the sealing ring 11 terms are used more in this paper, but it does not exclude the possibility of using other terms.
