Description

Technical Field

[0001] The utility model relates to the technical field of extracting container liquid, in particular to a red wine liquid extractor. Background Art

[0002] Existing wine extractors simply pump the wine into a storage container (such as a wine glass), which the user then needs to shake. Shaking the container serves two main functions: first, it aerates the wine, allowing it to fully come into contact with air and "breathe." Second, it releases the wine's aroma, allowing it to fully release its flavor. Both functions enhance the wine's flavor, making it more refined and full of character.

[0003] Some existing liquid extractors have an additional air pump to deliver gas to the liquid outlet channel to mix the gas and liquid for sobering up. However, the gas-liquid mixing is insufficient, and the addition of the air pump increases the volume of the liquid extractor.

[0004] Therefore, further improvement is needed. Utility Model Content

The gas-liquid mixing chamber (24) is provided between the liquid inlet chamber (23) and the air inlet chamber (25). The housing (19) is further provided with an oblique transmission member (26) and a leather cup (27) in a deformable state. The leather cup (27) is provided with a plurality of deformation chambers (28) located below the liquid inlet chamber (23), the gas-liquid mixing chamber (24) and the air inlet chamber (25). The leather cup (27) is connected to the oblique transmission member (26), and the motor (20) is provided with a drive shaft (30) which is inserted into the housing (19) and forms an eccentric transmission connection with the oblique transmission member (26); One end of the liquid inlet cavity (23) is connected to the input end (4), and the other end of the liquid inlet cavity (23) is provided with a liquid outlet (31); One end of the air inlet cavity (25) is connected to the air inlet end (6), and the other end of the air inlet cavity (25) is provided with an air outlet (33); One end of the gas-liquid mixing chamber (24) is connected to the gas-liquid mixing output end (5), and the other end of the gas-liquid mixing chamber (24) is provided with a liquid inlet (35) and an air inlet (36); The motor (20) runs and drives the driving shaft (30) to rotate. The driving shaft (30) drives the leather cup (27) to rotate through the oblique transmission member (26). The oblique transmission member (26) pulls the leather cup (27) to deform during the rotation. The multiple deformation chambers (28) of the leather cup (27) are alternately deformed and generate negative pressure. The multiple deformation chambers (28) alternately correspond to the liquid inlet chamber (23) and the air inlet chamber (25) during the rotation, so as to transport the liquid in the liquid inlet chamber (23) along the liquid outlet (31) and the liquid inlet (35) to the gas-liquid mixing chamber (24), and transport the gas in the air inlet chamber (25) along the air outlet (33) and the air inlet (36) to the gas-liquid mixing chamber (24).

9. The red wine extractor according to claim 8, characterized in that: The housing (19) comprises an upper housing (21) and a lower housing (22); a liquid inlet chamber (23), a gas-liquid mixing chamber (24) and an air inlet chamber (25) are arranged on the upper housing (21); and the motor (20) is fixedly arranged below the bottom of the lower housing (22).

10. The red wine extractor according to claim 8, characterized in that: The liquid inlet cavity (23) is provided with a first deformable sealing sheet (32) for sealing the liquid outlet (31), and the air inlet cavity (25) is provided with a second deformable sealing sheet (34) for sealing the air outlet (33); the gas-liquid mixing cavity (24) is provided with a third deformable sealing sheet (29) for sealing the liquid inlet (35) and the air inlet (36); When one of the deformation chambers (28) of the leather cup (27) rotates to the bottom of the liquid inlet chamber (23) or the air inlet chamber (25) and generates negative pressure, the liquid in the liquid inlet chamber (23) pushes open the first deformation sealing sheet (32) under the action of the negative pressure and pushes open the third deformation sealing sheet (29) through the deformation chamber (28) to enter the gas-liquid mixing chamber (24); while the gas in the air inlet chamber (25) pushes open the second deformation sealing sheet (34) under the action of the negative pressure and pushes open the third deformation sealing sheet (29) through the deformation chamber (28) to enter the gas-liquid mixing chamber (24).
