Description

a distributor

Technical field

The invention belongs to the technical field of wine drinking equipment and relates to a dispenser.

Background technique

The distributor is a device that is connected to the top of the beer barrel and cooperates with the wine spear in the beer barrel to lead the wine out of the beer barrel. The operator pulls the handle on the distributor, which can drive the wine pipe in the distributor to telescopically move. When the wine pipe moves downward, it can push down the valve core on the wine lance, causing the wine path to open, and at the same time, the external air The source can also be connected to the wine barrel, allowing the gas to enter the wine barrel through the distributor and the wine spear in sequence, thereby pressing out the wine in the wine barrel.

More traditional distributors such as the wine outlet valve of a beer barrel disclosed in the patent document (Application No.: 201310513342.9), that is, the distributor, include a valve body, a wine guide pipe and a handle. The center of the valve body has a penetrating guide hole, and the side of the valve body The bottom part has an air inlet pipe that communicates with the guide hole. The wine guide pipe is also called the top core. It is located at the guide hole and is sealingly connected to the valve body. An air outlet that can communicate with the inside of the beer barrel is formed between the bottom of the valve body and the wine guide pipe. , the handle is hinged on the valve body and is connected with the wine guide pipe. The side of the wine guide pipe has an air inlet structure. The handle of the wine outlet valve is hinged on the valve body, and the protrusion on the handle is always stuck in the wine guide pipe. In the groove of the two, the linkage between the two is realized, so the wine pipe is difficult to disassemble from the valve body, unless the handle is removed. The wine outlet valve is usually used as a non-detachable whole, and the whole is rinsed after use, but with the food Safety requirements have increased, and overall flushing, especially the inside of the wine tube, is troublesome. Therefore, a replaceable dispenser for the wine tube has emerged, and the wine tube can be replaced directly after use.

For example, the patent document (Application No.: 201880051409.2) is a dispensing system for dispensing beverages, including a one-way distribution pipeline and a distribution head. The one-way distribution pipeline includes a flexible pipe and a connection unit. During assembly, the connection unit is inserted into the distribution head and pulled. The actuating handle can press the connection unit downward into the distribution head, and the lower end of the connection unit can push down to open the valve and open the wine path. Then it is necessary to manually operate the gas cut-off element at the gas inlet to open the gas path and the gas source. Press gas into the barrel through the air path to press out the wine in the barrel. It is also necessary to manually close the gas cutoff component in advance during disassembly. Otherwise, the gas from the gas source will be removed when the distribution head is removed from the barrel and the connection unit is disassembled. Leakage causes waste, and then the actuating handle is pulled for disassembly. It can be seen that the distribution system requires manual operation of the gas cut-off unit when disassembling and assembling the connection unit, making the disassembly and assembly of the connection unit more troublesome.

Contents of the invention

The purpose of the present invention is to solve the problem of the above-mentioned problems existing in the existing technology and to propose a dispenser to solve the troublesome problem of disassembling, assembling and replacing the top core of the existing dispenser.

The object of the present invention can be achieved through the following technical solutions: a distributor, including a valve body, a cylindrical top core and a handle capable of pressing the top core downwardly into the valve body cavity from the upper end of the valve body. There is an air inlet hole, which is characterized in that the inner end of the air inlet hole penetrates to the inner cavity side wall of the valve body, and an air path core is provided in the air inlet hole and the air path core is directed toward the air inlet hole. The inner end direction acts on the valve body and blocks the air inlet hole. The inner end of the air path core has a structure that can protrude from the inner end of the air inlet hole to the inner cavity side of the valve body when the air inlet hole is blocked. The working part of the wall, the outer surface of the top core has a concave and convex structure, and when the top core is pressed down into the valve body cavity, the concave and convex structure can push the working part to make the air inlet conductive.

The top core is pressed downwards into the valve body cavity from the upper end of the valve body by the handle. Therefore, after the handle releases the top core, the top core can also be pulled out from the upper end of the valve body, making the top core removable and replaceable. The outer end of the air hole is connected to a gas source such as a high-pressure gas bottle through a trachea. Since there is a gas path core in the air inlet hole, before the top core is assembled, the gas path core is pressed against the valve body under the action of the elastic member and blocked. The air inlet hole prevents gas cylinder leakage, so there is no need to close the gas cylinder valve. When assembling the top core, buckle the valve body on the wine spear of the wine barrel. The top core is cylindrical. Insert it vertically from the upper end of the valve body. Pull the handle and press the top core downward. At this time, because the air path core is Sealing is achieved under the elastic force of the elastic member toward the inner end of the air inlet, and the working part on the air path core protrudes from the side wall of the inner cavity of the valve body, so the concave and convex structure can Push the working part protruding from the side wall of the valve body, causing the air path core to compress the elastic member to open the air inlet. At the same time, the lower end of the push core can press down the valve core of the wine lance to open the wine path, that is, by pulling the One-step operation of the handle simultaneously realizes the two functions of pushing the working part of the air path core to open the air inlet and pushing the valve core of the wine lance to open the wine path, and the two functions are realized simultaneously. When it is necessary to disassemble and replace the ejector core, pull the handle to release the ejector core. During the process of pulling out the ejector core upwards, the valve core of the wine spear loses the pressure from the lower end of the ejector core and gradually closes. The concave and convex structure on the ejector core is also separated from the working part. , the air path core blocks the air inlet hole again under the action of elastic parts. It can be seen that when assembling the top core of this distributor, only one step of pulling the handle is needed to simultaneously open the wine path and the air inlet. There is no need to operate the stop valve to open the air inlet after assembly. At the same time, When disassembling the top core, you only need to pull the handle in one step to close the wine path and the air inlet simultaneously. There is no need to close the stop valve first, so it is more convenient to disassemble and replace the top core.

In the above distributor, the concave-convex structure includes a radially protruding push portion on the outer peripheral wall of the top core. When the top core is pressed downward into the valve body cavity, the push portion can push the working part so that the air inlet hole conduction. The pushing part protrudes from the outer peripheral wall of the ejector core, so a convex and concave structure is formed between the two. When the ejector core is just inserted into the valve body cavity, the working part protrudes from the side wall of the valve body cavity or is in contact with the outer circumference of the ejector core. The wall has a gap, or only touches the outer peripheral wall of the top core, but the air path core is not pushed until the push part acts on the working part and can push the working part, causing the air inlet to open. As another method of concave-convex structure, the outer diameter of the top core can be made close to the inner diameter of the valve body cavity, so that the outer peripheral wall of the top core fits the inner wall of the valve body cavity, and a lower end is opened along the axial direction on the outer peripheral wall of the top core. A concave and convex structure is formed between the relief groove and the outer peripheral wall of the top core. When the top core is just inserted into the valve body cavity, the working part protruding from the side wall of the valve body cavity is located in the relief groove. In the groove, the air path core will not be pushed until the upper end of the groove wall acts on the working part and can push the working part, causing the air inlet to open.

In the above distributor, the push part is arranged circumferentially along the ejector core, and the lower end of the push part has a push cone surface arranged circumferentially with the small end facing downward. When the ejector core is pressed downward into the valve body When the cavity is in operation, the conical surface can be pushed up to push the working part to open the air inlet. By pushing the working part through the pushing cone surface, the air path core is gradually pushed, making the operation smoother and more labor-saving. The pushing cone surface surrounds the circumference, so the ejector core only needs to be inserted into the valve body, and there is no need to adjust the circumference of the ejector core. The angle is aligned with the working part, making the operation more convenient.

In the above distributor, the outer peripheral surface of the pushing part is a cylindrical surface, and the inner cavity side wall of the valve body is circumferentially provided with an annular sealing groove, and a rubber ring is provided in the sealing groove. It is located above the inner end orifice of the air inlet. When the ejector core is pressed downward into the valve body cavity, the outer peripheral surface of the push part slides with the side wall of the valve body cavity, and the outer peripheral surface of the push part is pressed against the rubber ring. After the ejector core is pressed into the valve body, the rubber ring is pressed tightly between the outer peripheral surface of the ejector part and the valve body, sealing the two to prevent gas from leaking upward from between the valve body and the ejector core. After the top core is assembled, the working part is always pressed against the outer circumferential surface of the push part, causing the top core to receive lateral force. Through the cooperation between the outer circumferential surface of the push part and the side wall of the lamp body cavity, the top core can be radially Limit the position in the direction to prevent the top core from shifting and affecting the sealing of the wine path and air path.

In the above distributor, the lower edge of the inner cavity side wall of the valve body has a conical relief surface with a large end facing downward along the circumferential direction, and the inner end of the air inlet hole penetrates to the lower part of the inner cavity side wall of the valve body, and The inner end of the air inlet hole penetrates to the relief cone surface. In order to limit the radial position of the ejector core, the outer circumferential surface of the ejector part is close to the side wall of the valve body cavity. This also causes the outer circumferential surface of the ejector part to block the air inlet hole and penetrate into the valve body after the ejector core is pressed down. The orifice on the side wall of the cavity, for this purpose, a relief cone surface is provided on the lower edge of the side wall of the valve body, and the inner end of the air inlet hole is penetrated to the relief cone surface, and the relief cone surface is connected with the outer peripheral surface of the push part Avoid gaps to prevent the inner end of the air inlet from being blocked.

In the above distributor, the inner end opening of the air inlet has a sealing convex edge in the circumferential direction, the sealing convex edge has a sealing tapered surface in the circumferential direction, the air path core is columnar, and the working part Located at the inner end of the air path core, the air path core is covered with a sealing ring. Under the action of the elastic member, the sealing ring can abut against the sealing cone surface to block the air inlet. This structure allows the air path core to be affected not only by the force of the elastic member, but also by the air pressure in the trachea, thereby making the sealing more stable. When the pushing part pushes the working part, the sealing ring breaks away from the sealing cone surface, and the air enters The hole is open.

In the above distributor, the working part is hemispherical, and the outer diameter of the working part is larger than the outer diameter of the air path core. When the sealing ring abuts the sealing cone surface, the spherical surface of the working part protrudes from the valve body. lumen side wall. By pushing the spherical surface of the working part through the pushing conical surface of the pushing part, the sliding friction between the two is smaller, making the operation smoother and more labor-saving.

In the above distributor, the outer wall of the air path core has a guide portion in the circumferential direction, and the outer peripheral wall of the guide portion is in sliding fit with the wall of the air inlet. The sealing ring is located between the guide portion and the working portion. A limit sleeve is screwed into the air inlet. The inner wall of the limit sleeve has a limit ring in its circumferential direction. The elastic member is a coil spring, and one end of the elastic member is sleeved on the air path core and abuts against the guide part. , the other end extends into the limit sleeve and abuts against the limit ring. Since the pushing force of the pushing cone facing the working part is a lateral force, the outer peripheral surface of the guide part is slidably matched with the wall of the air inlet hole to provide guidance for the movement of the air path core, thereby preventing the air path core from tilting etc., to ensure the sealing performance when the sealing ring and the sealing cone surface are in contact.

In the above distributor, the air inlet hole is arranged obliquely, and the inner end of the air inlet hole is lower than the outer end. The inner end of the air inlet hole is located at the lower part of the valve body, closer to the air inlet of the wine spear. There is also more space above the inner end of the air inlet hole for the setting of sealing and other structures to ensure the overall sealing effect of the air path.

In the above dispenser, the lower end of the valve body has an annular buckle portion, an annular sealing gasket is circumferentially fixed on the inner peripheral wall of the buckle portion, and the lower end of the top core has a small peripheral wall circumferentially. The closed cone surface is facing downward. The closed cone surface is located below the push cone surface. When the push core is pressed downward into the valve body cavity, the closed cone surface is pressed against the sealing gasket, and the working part is against the outer periphery of the push part. On the surface. When the valve body is buckled on the wine lance of the wine barrel through the buckling part, the sealing gasket is pressed downwardly against the upper end surface of the wine lance. When the top core presses downwards against the valve core of the wine lance, the closing cone surface is pressed against the sealing gasket. , thereby preventing gas from leaking from between the valve body and the wine spear when the pushing cone surface pushes open the working part.

Compared with the existing technology, this dispenser has the following advantages:

1. Since the working part on the air path core protrudes from the inner cavity side wall of the valve body, the top core can push the working part when it moves downward, causing the air path core to compress the elastic member and open the air inlet. At the same time, the lower end of the top core can press down the valve core of the wine spear to open the wine path. When the top core is disassembled, the air inlet hole and the wine path can also be closed at the same time. That is, the opening and closing of the air inlet hole and the wine path can be simultaneously realized in one step. The wine path has two functions: opening and closing, so it is more convenient to disassemble and replace the top core.

2. Since the top core can push the air path core through the pushing cone surface during the process of pressing into the valve body, and at the same time press the valve core of the wine lance through the lower end, the synchronization of the opening and closing of the wine path and the air inlet can be ensured.

3. Since the outer circumferential surface of the pushing part is close to the side wall of the valve body cavity, it also causes the outer circumferential surface of the pushing part to block the air inlet hole penetrating to the orifice on the side wall of the valve body cavity after the ejector core is pressed down. , for this reason, an escape cone surface is set on the lower edge of the side wall of the valve body, and the inner end of the air inlet hole is penetrated to the relief cone surface, so that there is no gap between the relief cone surface and the outer peripheral surface of the push part, thereby preventing the inlet from entering. The inner end orifice of the stomata is blocked.
