Abstract
Description
Technical Field
[0001] The utility model discloses a wine taking device, which is specifically a wine spear structure. Background Art
[0002] A wine barrel is a tool for holding wine. Generally, a wine spear is set at the mouth of the barrel. The wine spear cooperates with a dispenser to press the wine out of the barrel. Currently, beer in barrels is usually equipped with a wine spear at the mouth of the barrel. When taking beer, the dispenser presses carbon dioxide into the barrel. The carbon dioxide in the barrel can reduce the dissolved oxygen in the beer, thereby improving the flavor stability and shelf life of the beer.
[0003] At the same time, the carbon dioxide in beer can give beer a refreshing taste and rich foam, giving a comfortable stimulating feeling after drinking, which is the so-called mouthfeel. The carbon dioxide and organic acids in beer have a refreshing and invigorating function.
[0004] Currently, carbon dioxide is directly pressed into the barrel through a wine spear at the barrel mouth. The carbon dioxide entering the barrel is concentrated in the space above the wine. These carbon dioxide cannot be fully dissolved in the wine, so the effect is limited. Utility Model Content
[0005] The purpose of the utility model is to provide a beer spear structure, in which an air intake pipe is provided at the bottom of the air intake cavity of the beer spear and extends to the bottom or lower part of the barrel body, so that the carbon dioxide pressed into the barrel through the beer spear at the barrel mouth can be fully dissolved in the beer, so that the beer has a better taste.
[0006] To achieve the above objectives, the following technical solutions are adopted:
[0007] A wine spear structure, comprising a columnar valve body and an annular valve cover, characterized in that: the valve body has an air inlet cavity with an upper end opening, the outer side of the upper end extending outward to form a flange, the valve body is placed at the end of a wine barrel, the flange rests against the edge of the wine barrel, the valve cover is screwed onto the end of the wine barrel and presses the flange against the edge of the wine barrel; a wine outlet pipe is provided at an axial position within the air inlet cavity, the upper end of the wine outlet pipe is closed, a plurality of wine outlets are provided on the side wall of the wine outlet pipe near the upper end, and a sealing ring and a reset spring are sleeved on the wine outlet pipe The valve cover is provided with a valve spring, and the sealing ring is sealed with the side wall of the wine outlet pipe. The upper end of the return spring is against the bottom of the sealing ring, and the lower end of the return spring is against the bottom of the air inlet cavity. A limiting convex ring is provided on the outer side of the upper end of the wine outlet pipe. Under the action of the return spring, the sealing ring is against the limiting convex ring and the bottom of the valve cover and seals the upper end of the air inlet cavity. The lower end of the wine outlet pipe passes through the bottom of the air inlet cavity and extends downward. An air inlet is also provided at the bottom or side of the air inlet cavity, and an air inlet pipe is connected to the air inlet, which extends downward to the bottom of the wine barrel or near the bottom.
[0008] The air inlet is arranged at the bottom of the air inlet cavity, the lower end of the air inlet extends downward to form an air inlet interface, and the air inlet pipe is sleeved on the air inlet interface.
[0009] The wine outlet pipe includes an upper wine outlet pipe, a lower wine outlet pipe and a connecting pipe. The connecting pipe is an upper tube body and a lower tube body formed by extending upward and downward from the wine outlet hole at the center position of the bottom of the air inlet cavity. The lower wine outlet pipe is sleeved on the lower tube body. The inner wall of the upper tube body is provided with an internal thread, and the outer wall of the lower end of the upper wine outlet pipe is provided with an external thread. The upper wine outlet pipe is threaded and sealed with the upper tube body.
[0010] The utility model provides an air intake pipe at the bottom of the air intake cavity, which extends to the bottom or lower part of the barrel body, so that carbon dioxide can be fully dissolved in the beer, which can reduce the dissolved oxygen in the beer, improve the flavor stability and shelf life of the beer, and make the beer foam richer and taste better.
