Description

Gas pressurizing device of beverage container

Technical Field

The invention belongs to the technical field of beverage equipment, and relates to a gas pressurizing device of a beverage container.

Background

A beverage dispensing device is a device for dispensing a beverage (e.g., beer, coffee, soda, etc.) in a beverage container. Generally, the method is applied to commercial scenes such as bars, coffee shops and the like and home scenes such as parties and the like. The user can dispense the beverage quickly through the beverage dispensing device. Beverage dispensing devices include beverage containers, dispensers, taps, and the like, wherein, to ensure that beverage can be dispensed from the beverage container, the beverage container is typically filled with a high pressure gas, such as carbon dioxide gas, for applying pressure to the beverage within the container so that the beverage can be expressed from the container.

In the prior art, in order to avoid the shortage of air pressure of the beverage container, an air pressurizing device is generally arranged in the container to perform air compensation and pressurization, as disclosed in fig. 6 of Chinese patent document CN1125762C, the pressurizing device comprises an air bottle, a top cover connected to the air bottle and a piston slidably arranged in the top cover, the top cover is divided into an upper closed cavity and a lower cavity communicated with the inner cavity of the container by the piston, when the air pressure of the lower cavity fluctuates, the piston moves up and down under the action of the pressure difference of the upper cavity and the lower cavity, the piston is connected with an air tap of the air bottle through a trigger piece, and the piston can push the air tap to be opened through the trigger piece. The lower end of the trigger piece is inserted in the air hole of the air tap and fixedly connected with the air tap, the upper end of the trigger piece is provided with two pins, and the two pins are inserted in the piston. In order to prevent the situation that the pressurizing device is triggered by mistake due to air pressure fluctuation in the storage or transportation process before being mounted on the container, a triggering structure is further designed on the piston in the pressurizing device, before the pressurizing device is not triggered, the pins of the triggering piece are positioned in the sliding holes 475 of the piston, at the moment, the pressurizing device is in an un-triggered state, the triggering piece can slide relative to the piston, and even if the piston moves under the influence of the air pressure fluctuation, the triggering piece cannot move to open the air tap; when the pressurizing device is arranged in the container, the piston can be pushed to move upwards by high-pressure gas filled in the container, so that the pins are separated from the sliding holes and clamped on the piston, and the pressurizing device is triggered to be opened and is in a triggering state; at this time, if the air pressure of the piston fluctuates, the piston can adaptively adjust and move and drive the trigger piece to control the air tap to act.

The prior art gas pressurizing devices of the type described above have the following drawbacks: because the trigger piece is fixed with the air tap in a mode of being inserted into the air hole of the air tap, on one hand, when the piston presses the trigger piece to push the air tap, the trigger piece is easy to bend and deform after being used for many times, and finally, the piston cannot push the air tap to be opened completely, so that the air outlet of the air bottle is reduced and cannot meet the requirement to be scrapped; on the other hand, the trigger piece is plugged in the air hole, the air hole can be blocked, the air outlet amount of the air cylinder can be influenced, and finally the air cylinder is scrapped without being discharged, so that the service life of the air cylinder is influenced.
