Description

Technical Field

[0001] This utility model belongs to the field of tap technology, specifically referring to a beer tap. Background Technology

[0002] A beer tap is a special device used to dispense kegs of beer into open containers during consumption. A beer tap typically includes a valve and a nozzle to control and guide the beer into the open container.

[0003] A faucet, as disclosed in Chinese Patent Publication No. CN221300242U, includes a faucet body. One end of the faucet body has an inlet pipe for connecting to a container, and the other end has an outlet pipe for discharging liquid. The outlet pipe is integral with the inlet pipe and they are connected. The outlet pipe is perpendicular to the inlet pipe. A valve stem and an adjusting component are provided at the outlet pipe. The valve stem is vertically positioned along the outlet pipe and is movably connected to the inlet pipe. The adjusting component controls the movement of the valve stem. A blocking component is provided at the lower end of the valve stem; when the valve stem moves downward, the blocking component blocks the passage between the inlet and outlet pipes. Moving the valve stem controls the flow of the beverage. The end of the valve stem away from the blocking component extends out of the outlet pipe, and a handle is provided on this end. The handle is hinged to the valve stem, and an arc surface is provided at the hinge point. This arc surface abuts against the outer wall of the outlet pipe, causing interference between the handle and the outer wall of the outlet pipe. An elastic element is installed inside the water outlet pipe. One end of the elastic element is fixedly connected to the inner wall of the water outlet pipe, and the other end is fixedly connected to a blocking element. The elastic element has the tendency to push the blocking element to block the passage between the water inlet and outlet pipes. The elastic element includes a spring and a rubber block. Under the action of elasticity and gravity, the blocking element moves in the direction of blocking the passage. The blocking element pulls the valve stem, causing the handle to move vertically with the valve stem. When you need to take out a beverage, simply turn the handle to pull up the valve stem, thereby opening the passage. After releasing the handle, the valve stem will be pushed back to its original position to block the passage.

[0004] The above technical solution has at least the following drawbacks: the structure of the above faucet is relatively complex and the production cost is high. Moreover, the use of a spring as an elastic element requires the user to manually maintain the rotation angle of the handle in order to maintain the valve stem in the pulled-up state and thus maintain the dispensing state of the faucet. The operation is not convenient. Furthermore, the durability of the spring reset method is limited, and the service life of the faucet is limited. Utility Model Content
