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. In addition to being used to lead out the wine in the barrel, it also needs to be removed under the action of the handle. Press and push down the valve core of the wine lance to connect the wine path and the air path. An air outlet is formed between the bottom of the valve body and the wine guide tube that can communicate with the inside of the beer barrel. The handle is hinged on the valve body and the handle is connected to the wine guide tube. The pipes are connected, and the side of the wine pipe has an air inlet structure. The handle of the wine outlet valve is hinged on the valve body, and the convex head on the handle is always stuck in the groove of the wine pipe to realize the linkage between the two. Therefore, It is difficult to disassemble the wine pipe from the valve body unless the handle is removed. The wine outlet valve is usually used as a non-detachable whole, and the whole body needs to be flushed after use. However, with the improvement of food safety requirements, and the overall flushing, especially for the pipe Rinsing the inside of the wine tube is also troublesome, so there is a dispenser with replaceable wine tubes, and the wine tube can be replaced directly after use.

For example, the patent document (Application No.: 201880051409.2) discloses a distribution system for dispensing beverages, including a one-way distribution pipeline and a distribution head. The one-way distribution pipeline includes a flexible tube and a connection unit. The connection unit is also called a top core. A valve used for the passage of wine and downward pressure on the wine barrel. The connection unit includes a first part and a second part. The lower end of the first part is plugged into the upper end of the second part. The two are connected by a tight fit. They need to be assembled during assembly. The connection unit is inserted downward from the upper end of the distribution head. After the connection unit falls in, the actuating handle is pulled downward. The actuating handle can press the connection unit downward, and the lower end of the connection unit presses down the valve on the wine barrel. The actuating handle has protruding legs, the top of the first part has a convex part, and the convex part has a flange. When disassembled, the legs on the actuating handle hook the flange, thereby lifting the first part upward and Separate from the second part which is left inside the dispensing head.

However, there are shortcomings in the above structure. First, since the connection unit is a columnar structure with a large outer diameter at the upper end and a small outer diameter at the lower end, the position is relatively deep when it is placed in the distribution head. Therefore, when the handheld connection unit is inserted into the distribution head, the connection The unit will not come into contact with the distribution head. At this time, the connecting unit needs to be released to let it fall freely for a larger distance until the lower end of the connecting unit contacts the valve on the barrel. However, if there is a certain Deflection, especially if the posture when releasing is not accurate, will easily lead to a certain overall deflection when the connecting unit falls, jamming of the connecting unit and the inner wall of the distribution head, inaccurate contact position of the valve between the lower end and the wine barrel, etc., which will affect the connection. The phenomenon of final accuracy of the unit, and then pressing down of the actuating handle will also lead to inaccurate cooperation between the connecting unit and the valve on the wine barrel, affecting the sealing effect of the wine path. This requires accurate alignment and correction every time the connecting unit is put in. Not easy to operate. Secondly, when disassembling, you need to manually apply force to lift the connection unit, and only the first part can be taken out. The second part will be left in the distribution head body and is difficult to take out, making disassembly inconvenient.

Contents of the invention

The purpose of the present invention is to solve the problem of how to ensure the matching accuracy between the existing dispenser and the wine spear after assembly on the basis of easy disassembly and assembly of the existing dispenser.

The object of the present invention can be achieved by the following technical solutions: a distributor, including a valve body and a cylindrical top core. The valve body is hinged with a device that can move downward when the top core is inserted from the upper end of the valve body in a vertical state. The handle for pressing the top core is characterized in that the valve body is provided with an elastic member with its lower end abutting and supported on the valve body, and the outer wall of the top core has a radially protruding abutment portion located at The upper part of the top core, when the top core is inserted downward into the valve body, the resisting part can press downward against the upper end of the elastic member and compress the elastic member downwards under the pressure of the handle.

The top core is inserted into the valve body from the upper end of the valve body and pressed downward into the valve body through the handle. After the handle releases the top core, the top core can also be taken out from the upper end of the valve body, making the top core removable and replaceable. An elastic member is provided in the valve body. The lower end of the elastic member is supported on the valve body and can generate upward elastic force. The outer wall of the top core has a resisting portion, and the resisting portion is located on the upper part of the top core. Therefore, the assembly First buckle the valve body on the wine spear of the wine barrel, then hold the top core and insert it into the valve body from the upper end of the valve body in a vertical state. The top core will not fall freely, but the lower end will pass through the top core. Elastic parts, the top core is placed on the elastic part, so that the abutment part is hung on the upper end of the elastic part. This process is performed by holding the top core, and after the top core is released, it has been supported by the elastic part. None of them exist. During the free falling process of the top core, since the abutment part is on the upper part of the top core, the lower end of the top core hangs freely, making itself vertical through its own center of gravity. The posture is more accurate and there is no need to repeat calibration during the assembly process. The position and posture of the top core make assembly more convenient, and then the upper end of the top core is acted on through the handle. Its acting position is relatively close to the position where the elastic member acts, which enables the top core to be supported stably on the elastic member, and the handle will be attached When the top core is pressed down on the elastic member, during the process of compressing the elastic member, the top core is also pressed against the handle by the elastic member, so that the top core is always restrained during the process of pressing down, and then after the top core is pressed down, the top core is pressed down on the handle. The position is more precise to ensure the accuracy of matching with the wine spear. After the top core is assembled, the elastic member is in a compressed energy storage state. Therefore, when disassembling the top core, you only need to pull the handle upward to release the top core. The elastic member can bounce the top core upwards. There is no need to manually lift the top core, and disassembly is relatively easy. convenient.

In the above distributor, the upper end of the elastic member is located at the upper end port of the valve body, and the upper end port of the valve body is also connected to a limiter for the upper end of the elastic member to abut upward before the top core is inserted into the valve body. pieces. The upper end of the elastic member is located at the upper end port of the valve body. Therefore, when the top core is inserted by hand, the abutment part can be pressed against the upper end of the elastic member, so that the top core can be supported by the elastic member in time. Before the top core is inserted, the elastic member The upper end of the elastic member is against the limiter, so the elastic member is in a certain state of compression and maintains a certain elastic support force to prevent the abutment part from abutting the upper end of the elastic member and releasing the top core due to its own gravity. Falling affects the stability and ensures the accurate posture of the top core.

In the above distributor, the limiter includes a limiter ring fixed in the upper end port of the valve body. The limiter ring is coaxially arranged with the valve body cavity, and the inner peripheral wall of the limiter ring protrudes radially inward. From the side wall of the valve body cavity, before the top core is inserted into the valve body, the upper end of the elastic member presses upward against the lower end surface of the limiting ring. The structure of the limit ring is more regular, which is used to abut the upper end of the elastic member and prevent the elastic member from falling out of the valve body after the top core is disassembled.

In the above distributor, the abutment part is annular, and the outer circumferential surface of the abutment part is a cylindrical surface. When the top core is inserted downward into the valve body, the outer circumferential surface of the abutment part is in sliding fit with the inner circumferential surface of the limiting ring. . Since the elastic member is located below the limiting ring, the outer peripheral surface of the resisting portion and the inner peripheral surface of the limiting ring have already contacted and slidably matched before the resisting portion abuts against the elastic member, so that the limiting ring is in contact with the upper end of the top core Provide guidance to ensure the posture and stability of the top core.

In the above-mentioned distributor, the inner peripheral wall of the lower part of the valve body has an annular guide part in the circumferential direction, and the lower end of the above-mentioned elastic member is supported downwardly on the upper end surface of the guide part. When the top core is inserted downward into the valve body, The outer circumferential surface of the top core is in sliding fit with the inner circumferential surface of the guide part. During the pressing process of the ejector core, the outer circumferential surface of the ejector core and the inner circumferential surface of the guide part slide and cooperate, so that the guide part guides the lower end of the ejector core. The guide part is combined with the limiting ring, thereby making the ejector core more stable and pressing down. The final position accuracy is higher, thus ensuring the matching accuracy between the top core and the wine spear.

In the above distributor, a pressure relief groove is provided along the axial direction on the inner circumferential surface of the limit ring. Both ends of the pressure relief groove penetrate through the two end surfaces of the limit ring respectively. The upper end of the limit ring The inner edge has an introduction tapered surface along the circumferential direction. After the top core and the valve body are assembled, an air inlet channel is formed between the lower end of the top core and the valve body. In order to prevent gas from leaking from between the top core and the valve body, a sealing groove is opened on the inner peripheral surface of the guide part. There is a rubber ring to form a seal with the outer circumferential surface of the top core, and the outer circumferential surface of the abutment part and the inner circumferential surface of the limit ring also form a sliding fit, making it difficult for the air under the top core abutment part to be discharged. A pressure relief groove is provided on the inner circumference of the ring to discharge the air when the top core is assembled and pressed down. The pressing operation is more labor-saving. When the top core is disassembled and bounced up, air enters. The bounce is smoother under the action of the elastic member, and the introduction cone surface can When the top core is inserted, the end of the top core is guided to make the insertion more convenient and faster.

In the above-mentioned distributor, the inner wall of the upper end port of the valve body has a relief groove in the circumferential direction, the limit ring is located in the relief groove, and the outer circumferential surface of the limit ring is connected to the wall of the relief groove through a threaded fit. . The limit ring and the valve body are connected through a threaded fit, so the height of the limit ring can be adjusted, and the position of the upper end of the elastic member and the pre-tightening force can be adjusted to match different types of top cores to improve versatility.

In the above-mentioned dispenser, the elastic member includes a plurality of butterfly springs, which are stacked vertically in sequence, and the lowermost butterfly spring is pressed downwardly against the upper end surface of the guide portion, and the uppermost butterfly spring can It abuts upward on the lower end surface of the limiting ring, and the inner edge of the butterfly spring protrudes radially inward from the inner circumferential surface of the limiting ring. There is a certain width between the inner edge and the outer edge of the butterfly spring. When the top core is not inserted into the valve body, the outer edge can abut against the lower end surface of the limit ring, and when the top core is inserted, it can abut against the inner edge.

In the above-mentioned dispenser, the top core is provided with a wine outlet hole along the axial direction, and a nozzle is fixed at the upper end of the wine outlet hole. There is a penetrating installation gap, and a clamping piece that can be clamped on the outer wall of the pipe when the handle is pressed downward on the top core is fixed in the installation gap. The nozzle is used to connect the hose, and the installation gap is used for the nozzle to pass through to avoid interference with the handle. The clamping piece can clamp the nozzle, so when the handle is pulled upward, it can produce upward pulling force on the nozzle, which can assist the elasticity. The piece facilitates the extraction of the top core from the wine spear in the early stages of disassembly. This structure serves as a safeguard to prevent the elastic member from being difficult to eject the top core due to the tight fit between the seal in the wine spear and the top core.

In the above dispenser, the clamping piece includes a clamping block fixed in the installation notch. The clamping block is made of rubber material. The side wall of the clamping block is provided with a clamping opening that penetrates up and down. , the width of the clamping opening is smaller than the outer diameter of the nozzle, and when the handle is pressed downward on the top core, the nozzle is inserted into the clamping opening. The clamping piece is a rubber clamping block instead of a linkage component. The structure is simplified and the top core is pulled upward through friction. This structure also facilitates the disassembly and assembly of the nozzle and handle.

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

1. Since the top core is inserted into the valve body until the abutment part abuts against the upper end of the elastic member, the operation is performed by holding the top core. After the top core is released, it has been supported by the elastic member, and there is no free movement of the top core. During the falling process, the abutment part is on the upper part of the top core, so the lower end of the top core hangs freely, making itself vertical through its own center of gravity. The posture is more accurate, and there is no need to repeatedly calibrate the top core during the assembly process. The position and posture make assembly more convenient.

2. Since during the process of compressing the elastic part, the top core is also pressed against the handle by the elastic part, so that the top core is always restrained during the process of pressing down, and the position of the top core after being pressed down is more accurate, ensuring that the top core is pressed down. The matching accuracy of the wine spear.

3. Since the elastic part is in a compressed energy storage state after the top core is assembled, when disassembling the top core, you only need to pull the handle upward to release the top core. The elastic part can bounce the top core upwards, and there is no need to manually lift the top core. , disassembly is more convenient.

4. Since the upper end of the elastic member is against the stopper before the top core is inserted, the elastic member is in a certain compression state and maintains a certain elastic support force to prevent the abutment part from abutting and releasing the upper end of the elastic member. When the core is lifted, it falls rapidly due to its own gravity, which affects the stability and ensures that the posture of the core is accurate.
