Valve device adopting power-free air blowing to remove residual wine and wine dispenser

Abstract

The invention discloses a valve device adopting power-free air blowing to remove residual wine and a wine dispenser. The valve device comprises a valve body and an operating piece. The valve body is internally provided with a wine inlet passage and a wine outlet passage which communicate with each other. The operating piece is provided with a first work position and a second work position. The valve body is further internally provided with an air inlet passage, an air outlet passage, a transitional air chamber and an air storage chamber. The air inlet passage, the air outlet passage, the wine outlet passage and the air storage chamber are connected with the transitional air chamber. When the operating piece is located in the first work position, the air inlet passage, the air outlet passage and the air storage chamber are connected with the transitional air chamber, and the wine outlet passage is disconnected with the transitional air chamber; and when the operating piece is located in the second work position, the air inlet passage and the air outlet passage are disconnected with the transitional air chamber, and the wine outlet passage and the air storage chamber are connected with the transitional air chamber. The valve device adopting power-free air blowing to remove the residual wine and the wine dispense have the beneficial effects that operation is easy, the structure is ingenious, and the control process does not need to consume power energy.

Description

technical field [0001] The invention belongs to the technical field of wine dispensing devices for bottled wine, and in particular relates to a valve device and a wine dispensing machine for removing residual wine by blowing air without electricity. Background technique [0002] In the current wine dispensers on the market, we can observe that there is a "pneumatic blowing" system: after the machine finishes dispensing wine, this system generates a stream of gas and injects it into the wine outlet channel to blow out the remaining wine in the outlet channel. ; In this way, part of the wine remains in the wine outlet channel. If part of the wine remains at the outlet of the wine outlet, it will be oxidized, and when a glass of wine is taken again, the residual oxidized wine will affect the taste. For some of the more expensive wines, this is especially to be avoided. [0003] The existing machine is aimed at the system of blowing out the residual wine at the outlet, and ado...

The utility model patent with application number "201220666162.5" and titled "Automatic Wine Dispenser for Keeping Fresh and Refrigerated Wine without Residual Liquid in Wine Spout" discloses a wine dispensing machine. In this patent, the solution to the residual liquid in wine spout is to use Solenoid valve control, so that the gas from the gas storage bottle can clean the residual wine in the wine spout, but the defect of this method is: the solenoid valve needs to be driven by electricity, and an expensive circuit board is realized through program control; using this method The machine, its wine and gas passage is also controlled by solenoid valves, the most important thing is that these circuit boards and solenoid valves need to occupy a certain space, so the machine itself has a large volume and is not easy to maintain, and it also affects the appearance
