Description

Technical Field

[0001] The present invention belongs to the technical field of drinking equipment and relates to a beer outlet joint for a beer barrel. Background Art

[0002] As a relatively common beverage in today's life, beer is widely favored by consumers due to its unique taste. Under further classification, there are various types of beer. In terms of storage methods, it includes canned and barreled beer, and the latter has a better taste. Among them, the beer barrel used to hold beer is generally called a beer barrel in the industry.

[0003] For example, a beer barrel disclosed in Chinese Patent CN220578919U includes a barrel body connected with an outlet valve. The outlet valve has an outlet channel, and a valve core for controlling the opening and closing of the liquor path is slidably connected in the outlet channel. The beer barrel further includes a joint assembly with a flow channel inside and detachably connected to the outlet valve. The joint assembly extends into the outlet channel and abuts against the valve core. A diversion head for blocking a part of the inlet end of the flow channel is arranged in the joint assembly, and a gap is formed between the outer wall of the diversion head and the inner wall of the flow channel. The joint assembly specifically includes a top core with a through hole inside, a joint pipe bent in an L shape, and an outlet pipe. When taking beer, the joint assembly is docked with the outlet valve on the barrel body. When the valve core is extruded, the beer liquid is ejected from the outlet channel. During this process, the beer liquid enters the top core of the joint assembly. Due to the existence of the diversion head, most of the pressure of the beer liquid is blocked, and a small part of the beer liquid flows into the overflow groove of the diversion head through the gap for further pressure stabilization, and then slowly flows out through the joint pipe and the outlet pipe in sequence, avoiding the generation of a large amount of foam during the process of drawing beer liquid and ensuring the taste of the drawn beer liquid.

[0004] Although the joint assembly designed in the above-mentioned existing beer barrel reduces the generation of beer outlet foam relatively well, through research, the above-mentioned joint assembly still has the following deficiencies: 1. Since the diversion head, also known as the diversion cone, is arranged vertically in the outlet channel composed of the top core and the joint pipe, although the beer liquid eliminates a certain amount of foam under the action of the diversion cone, when it enters the horizontally arranged outlet transverse hole of the joint pipe, it is easy to be blocked and impacted by the inner wall of this area at the corner of the outlet transverse hole and the above-mentioned vertical outlet channel, resulting in secondary foam; 2. In this joint assembly, the small end of the diversion cone is inserted into the top core, and then the top core is inserted into the joint pipe and the diversion cone is pressed against the shoulder at the inner end of the vertical hole of the joint pipe, thereby realizing the fixation of the diversion cone. However, such a design also causes the shoulder to block the beer liquid flowing through this place, resulting in easy foaming at this place. Summary of the Invention

[0005] The object of the present invention is to address the above problems existing in the prior art and propose a beer tap for a beer barrel. The technical problem to be solved by the present invention is how to better reduce the beer foam during pouring.

[0006] The object of the present invention can be achieved by the following technical solutions: A beer tap for a beer barrel includes a body and a flow guiding cone. The body has a vertically opened beer outlet vertical hole and a horizontally opened beer outlet horizontal hole. The upper end of the beer outlet vertical hole is communicated with the inner end of the beer outlet horizontal hole. The body also has a connection hole communicated with the outer end of the beer outlet horizontal hole. It is characterized in that the flow guiding cone is horizontally arranged in the beer outlet horizontal hole. The small end of the flow guiding cone is fixed on the bottom of the inner end of the beer outlet horizontal hole, so that the whole flow guiding cone is suspended relative to the hole wall of the beer outlet horizontal hole. A beer passing gap is formed between the outer peripheral surface of the flow guiding cone and the hole wall of the beer outlet horizontal hole. The large end of the flow guiding cone is located at the port of the outer end of the beer outlet horizontal hole. The flow guiding cone, the beer outlet horizontal hole and the connection hole are coaxial, and the outer diameter of the large end of the flow guiding cone is smaller than the inner diameter of the inner port of the connection hole.

[0007] In view of the situation of secondary foaming occurring during the wine outlet process of the existing wine outlet connector, those skilled in the art can easily think of using a technical means of arranging another defoaming structure at the outlet end of the wine outlet connector to reduce the generation of foam. Different from the existing conventional means, in this application, by changing the structure of the wine outlet connector, that is, canceling the design of the existing top core, and making ingenious improvements to the setting position and fixing method of the diversion cone and its cooperation relationship with the surrounding components, the problem of secondary foaming is well solved. Specifically, in this application, the diversion cone is arranged in the horizontal wine outlet hole, and a wine passing gap is formed between the outer peripheral surface of the diversion cone and the hole wall of the horizontal wine outlet hole. When the wine liquid flows out from the vertical wine outlet hole and enters the horizontal wine outlet hole, since the horizontal wine outlet hole is the last section of the flow path of the wine outlet connector, the wine liquid that has undergone the defoaming effect of the diversion cone will directly output from the wine passing gap to the wine outlet pipe or wine outlet nozzle installed in the connection hole, so that the wine liquid after the first defoaming effect of the diversion cone can be prevented from secondary foaming in the wine outlet connector, thereby better reducing the generation of wine outlet foam; at the same time, the small end of the diversion cone is fixed on the bottom of the inner end of the horizontal wine outlet hole so that the diversion cone forms a single-end fixation, which enables the whole diversion cone to be suspended relative to the horizontal wine outlet hole. That is to say, the wine liquid flowing inside the wine passing gap will not be blocked, thereby avoiding the generation of secondary foam inside the wine passing gap; moreover, the above single-end fixation method also makes it unnecessary for the large end of the diversion cone to cooperate with other positioning or fixing components. Coupled with the fact that the large end of the diversion cone is located at the outer end port of the horizontal wine outlet hole, and at the same time, in cooperation with the design that the diversion cone, the horizontal wine outlet hole, and the connection hole are coaxial and the outer diameter of the large end of the diversion part is smaller than the inner diameter of the inner port of the connection hole, the wine liquid that has undergone the buffering effect of the diversion cone and flows out along the diversion cone from the wine passing gap will not be additionally blocked and impacted when flowing out further, thereby further avoiding the generation of secondary foam; therefore, through the above improved design of the wine outlet connector, the generation of wine outlet foam can be finally better reduced.

[0008] In addition, since the existing top core design is canceled in this wine outlet structure, not only the number of components of the connector is reduced, which is beneficial to cost reduction, but also the installation of the diversion cone is more convenient, thereby making the assembly of the connector more convenient.

[0009] In the above-mentioned wine outlet connector for a beer barrel, a fixing hole is opened at the bottom of the inner end of the horizontal wine outlet hole, and a columnar connecting part extends coaxially from the small end of the diversion cone, and the connecting part is inserted and fixed with the fixing hole. Through the design of the above connecting part, the whole diversion cone can be suspended relative to the horizontal wine outlet hole, which is more conducive to avoiding the generation of foam when the wine liquid enters the initial section of the wine passing gap; moreover, since the fixing hole is opened at the bottom of the inner end of the horizontal wine outlet hole, the fixing structure of the insertion fit between the connecting part and the fixing hole is arranged outside the horizontal wine outlet hole, and this fixing structure will not affect the wine liquid flow, which is also beneficial to better reducing the generation of wine outlet foam.

[0010] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the cross-section of the connecting part is circular, and its outer diameter is the same as the outer diameter of the small end of the diversion cone. Through the above design, since there are no sharp parts at the connecting part and the junction of its small end and the diversion cone, when the wine liquid collides with the connecting part and the diversion cone, it is conducive to better reducing the generation of foam.

[0011] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the junction of the diversion cone and the connecting part is directly above the upper port of the vertical wine outlet hole, and the outer diameter of the connecting part is greater than the inner diameter of the upper port of the vertical wine outlet hole. Through the above design, when the wine liquid rushes out from the vertical wine outlet hole, it can be blocked by the junction of the diversion cone and the connecting part and the wine liquid can be shunted and buffered here immediately. While offsetting the impact force of the wine liquid, part of the wine liquid can be introduced into the wine passing gap, thereby reducing the impact of the wine liquid on the inner end hole wall of the horizontal wine outlet hole, and further better reducing the generation of wine outlet foam.

[0012] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the horizontal wine outlet hole and the connecting hole are connected through a flared opening in a conical shape. The small end of the flared opening faces the horizontal wine outlet hole and its inner diameter is greater than the inner diameter of the outer end port of the horizontal wine outlet hole. Through the above flared opening design, the height difference generated between the inner wall of the horizontal wine outlet hole and the inner wall of the connecting hole can be compensated, so that the defoamed wine liquid can flow into the connection more smoothly from the horizontal wine outlet hole, and further is conducive to better reducing the generation of wine outlet foam.

[0013] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the horizontal wine outlet hole is successively divided into three sections from inside to outside, namely a cylindrical inflow section, a conical buffer section, and a cylindrical outflow section. The upper end of the vertical wine outlet hole is connected to the inflow section, and the outflow section is connected to the connecting hole. Through the above design of the shape of the horizontal wine outlet hole, it can cooperate well with the diversion cone and play a better defoaming role, thereby being conducive to better reducing the generation of wine outlet foam.

[0014] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the edge of the fixed hole port has a conical guiding surface, and the inner port of the horizontal wine outlet hole and the fixed hole are transitioned through the guiding surface. Through the above design, on the one hand, it makes the installation of the diversion cone more convenient; on the other hand, the guiding surface also makes the corner around the inner end hole bottom of the horizontal wine outlet hole larger. In this way, when the wine liquid impacts here, it is conducive to better reducing the generation of wine liquid foam.

[0015] In the above-mentioned beer and carbonated beverage barrel's wine outlet connector, the inner diameter of the vertical wine outlet hole is smaller than the minimum inner diameter of the horizontal wine outlet hole. Through the above design, the impact force of the wine liquid rushing out from the vertical wine outlet hole can be quickly buffered and released, which is conducive to better reducing the generation of wine outlet foam.

[0016] In the above-mentioned beer and carbonated drink barrel wine outlet connector, a wine outlet nozzle is inserted into the connection hole. There is a gap between the end face of the inner end of the wine outlet nozzle and the outer end face of the flow guiding cone, and the inner diameter of the port at the inner end of the wine outlet nozzle is larger than the outer diameter of the large end of the flow guiding cone. Through the above design of the size and installation position of the wine outlet nozzle, the defoamed wine flowing out from the large end of the flow guiding cone will not be blocked by the inner end of the wine outlet nozzle, thus avoiding the generation of secondary foam here, and further being able to better reduce the wine outlet foam.

[0017] In the above-mentioned beer and carbonated drink barrel wine outlet connector, the inner end port of the wine outlet nozzle is conical and the inner diameter of the small end is larger than the outer diameter of the large end of the flow guiding cone. Through the above design, it is possible to further avoid the blockage of the inner end of the wine outlet nozzle to the defoamed wine, thus avoiding the generation of secondary foam here, and further being able to better reduce the wine outlet foam.

[0018] Compared with the prior art, the wine outlet connector for beer and carbonated drink barrels of the present invention has the following advantages:

[0019] 1. By cleverly improving the setting position and fixing structure of the flow guiding cone, this wine outlet connector can avoid the secondary generation of foam after the first defoaming of the wine outlet connector, thus being able to better reduce the generation of wine outlet foam.

[0020] 2. This wine outlet connector cancels the existing top core design, has fewer parts, lower manufacturing costs, and is more convenient to assemble. Description of the Drawings
