Beer spear

Abstract

The invention provides a beer spear, and belongs to the technical field of beer drinking equipment. The problem of poor sealing performance of an existing beer spear is solved. The beer spear comprises a valve body. A fixing seat is connected inside the valve body. The upper end of the fixing seat is sleeved with a valve seat in a sliding mode. An air inlet passage is formed between the outer wall of the valve seat and the inner wall of the valve body. A spring I which enables the valve seat to move upwards and abut against the valve body to seal the air inlet passage is arranged in the valve body. A valve element is arranged in the fixing seat in a sliding mode. A beer outlet passage is formed between the outer wall of the valve element and the inner wall of the fixing seat. A spring II is arranged in the fixing seat. The valve element abuts against the fixing seat to form sealing under the action of the spring II. The valve seat is provided with a contact portion protruding downwards, or the valve element is provided with a contact portion protruding upwards. When the valve seat moves downwards to open the air inlet passage, the valve seat enables the valve element to move downwards to open the beer outlet passage through the contact portion. The beer spear has good sealing performance.

Description

Technical field [0001] The invention belongs to the technical field of wine drinking equipment and relates to a wine spear. Background technique [0002] A wine barrel is a tool for holding wine. Generally, a wine spear is set at the mouth of the wine barrel, and the wine spear cooperates with a dispenser to press out the wine in the wine barrel. At present, the commonly used wine barrels in the market are metal wine barrels. Metal wine barrels are expensive and troublesome to clean. Generally, businesses do not have special equipment for cleaning metal wine barrels. Therefore, when the wine in the wine barrel is used up, , The empty wine barrels need to be transported to the manufacturer for cleaning, which increases the cost of transportation back and forth. Moreover, when this kind of wine barrel presses out the wine, the gas is directly filled into the interior of the wine barrel, and the pressure of the gas is applied to the surface of the wine to press out the wine. In thi...

Problems solved by technology

At present, the wine barrels commonly used in the market are all metal wine barrels. Metal wine barrels are expensive and troublesome to clean. Generally, merchants do not have special equipment for cleaning metal wine barrels. Therefore, after the wine in the barrel is used up, , it is necessary to transport the empty wine barrels to the factory for cleaning, which increases the cost of transportation back and forth

Moreover, when this kind of wine barrel is pressing out the wine, the gas is directly filled into the inside of the wine barrel, and the pressure of the gas is applied to the surface of the wine to press out the wine. In this way, the gas and the wine need to be in contact, which is easy Cause beer to decline in wine quality due to oxidation and bacteria invasion

[0003] Further, as the Chinese invention patent application (application number: 201610792234.3) discloses a wine spear, including a valve body and a lower pipe body fixedly connected to the valve body, the upper pipe body is slidingly sleeved on the lower pipe body, A valve core is also slid in the lower body, wherein the upper body needs to form a seal with the lower body to separate the air intake path and the wine outlet path, and at the same time, the upper body needs to form a seal with the valve body to Block the air intake passage, and the upper pipe body needs to form a seal with the valve core to block the wine outlet passage, because the upper pipe body needs to form a seal with the valve body, lower pipe body and valve core at the same time, so the upper pipe body The location accuracy and the design accuracy of the whole wine spear put forward high requirements. At the same time, the processing accuracy and assembly accuracy of each component are high. At the same time, it is limited by the processing technology conditions. If the above components are made of plastic, it will be easier. Shrinkage deformation occurs, it is difficult to ensure the manufacturing accuracy, so it is difficult to ensure the sealing of the wine during use, and it is easy to leak the wine. Further, the wine spear needs to be used in conjunction with the dispenser when the wine is released, and the upper pipe body and the valve The core needs to be pressed down through different positions or parts of the distributor, so the stability of different positions or parts of the distributor must be guaranteed, otherwise it will affect the sliding stability of the upper pipe body and the valve core, and will eventually affect the sealing sex
