Description

Technical Field

[0001] This patent relates to a technology for preserving the remaining wine or sparkling wine in a wine bottle or a sparkling wine bottle, and in particular to a device that can evacuate air from a wine bottle and add air to a sparkling wine bottle. Background Art

[0002] As for wine, how to keep the remaining wine fresh after opening is a technology that people have been studying. Chinese utility model patent 201420348583.2 records an electric vacuum device for wine, which includes a charging base and a vacuum main body. When in use, the vacuum main body cooperates with a one-way valve placed at the mouth of the wine bottle to extract gas from the wine bottle. After the gas in the bottle is reduced, the remaining air in the wine bottle is reduced, which reduces the oxidation rate of the remaining wine in the bottle.

[0003] For sparkling wine, the gas in the bottle decreases after opening, which will affect the taste of the sparkling wine. In order to maintain the taste of the wine as much as possible, it is necessary to add carbon dioxide and other gases to the remaining wine.

[0004] The existing technology has defects, that is, the function is single, and a product can only pump air or only add air. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, this patent adopts the following technical solution: a device with the functions of exhausting and adding gas, including a shell and a power mechanism, a transmission mechanism, a piston, and a gas guide mechanism in the shell. The transmission mechanism transmits power to the piston and allows the piston to reciprocate. It also includes a gas filling mechanism, a gas extraction mechanism, and a conversion mechanism. The gas filling mechanism can be used in conjunction with the gas filling one-way valve on the sparkling wine bottle to add gas to the sparkling wine bottle and seal the bottle mouth to maintain the air pressure in the bottle. The gas extraction mechanism can be used in conjunction with the gas extraction one-way valve on the wine bottle to extract the gas in the wine bottle and seal the bottle mouth to maintain the air pressure in the bottle. The conversion mechanism switches the working state of the gas filling mechanism or the gas extraction mechanism, thereby controlling the closing or opening of the gas filling mechanism or the gas extraction mechanism.

[0006] In addition, this patent also simplifies and improves the transmission mechanism, piston, gas guide mechanism, gas filling mechanism, air extraction mechanism and conversion mechanism, reducing spare parts and production processes.

[0007] This patent provides a pressure relief device to relieve pressure when the pressure in the bottle is too high during the gas filling operation to prevent the bottle from breaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See Figure 2 , 3, 5, 6. The air filling mechanism and the air exhaust mechanism include a common air guide mechanism, which includes a hose (5.1) and an air nozzle hard tube (5.2). One end of the hose (5.1) is connected to the air nozzle hard tube (5.2) by air, and the other end of the hose (5.1) is connected to the knob hard tube (8.5) by air. The knob hard tube (8.5) and the knob (8.1) are integrally formed, and the knob hard tube (8.5) is connected to the air channel (8.2.1) on the sealing gasket (8.2) by air. It also includes a rotary cover (11), and a gas nozzle cavity (11.1) is provided in the rotary cover (11). The hose (5.1) and the gas nozzle hard tube (5.2) are both arranged in the gas nozzle cavity (11.1).

[0024] See Figure 1 , 2 , 3, 4, 5, 6. A buckle (8.6) and a positioning groove (8.7) are provided on the lower side of the knob (8.1), a screw cap groove (11.2) and a rib (11.3) are provided on the inner wall of the screw cap (11), the buckle (8.6) is inserted into the screw cap groove (11.2) for buckling connection, and the rib (11.3) is inserted into the positioning groove (8.7) for positioning.

[0025] When the remaining wine in the wine bottle is to be degassed, the screw cap (11) is rotated to drive the knob (8.1) to rotate, so that the device enters a degassed state: after the knob (8.1) is rotated to a certain angle, the protrusion (8.4) on the knob (8.1) is engaged with the concave position (10.3) in the valve seat (10) corresponding to the degassed sealing space (7.2), so that the sealing gasket (8.2) is aligned with the degassed check valve (7.1) and the surrounding wall where the degassed check valve (7.1) is located is closed. (10.2), at this time, the hose (5.1) rotates along with the air nozzle hard tube (5.2) on the rotary cover (11) and the knob hard tube (8.5) on the knob (8.1) and connects the through hole (9.1) at the bottom of the cylinder (9), the air extraction valve body space (7.5) and the air extraction sealing space (7.2), the air channel (8.2.1) on the sealing gasket (8.2), the knob hard tube (8.5), the hose (5.1) and the air nozzle hard tube (5.2) to form a gas channel.

[0026] Afterwards, the screw cap (11) is placed on the bottle stopper with the exhaust check valve at the mouth of the wine bottle, and the exhaust mechanism cooperates with the exhaust check valve placed at the mouth of the wine bottle to exhaust air from the wine bottle. In this exhaust state, the motor (2.2) is started, the worm (3.1) and the worm wheel (3.2) move, and the transmission connecting rod (3.4) drives the piston (4) to reciprocate. When the piston (4) moves from bottom to top, the air pressure in the cylinder (9) decreases. Due to the air pressure difference, the gas in the wine bottle flows from the wine bottle to the cylinder (9) through the air channel formed between the components. When the piston (4) moves upward, the exhaust check valve (7.1) opens and the gas filling check valve (6.1) closes. The gas extracted from the wine bottle enters the exhaust sealing space (7.2) through the exhaust check valve on the bottle stopper, the screw cap air nozzle (5.2), the hose (5.1), the knob hard tube (8.5), and the air channel (8.2.1) on the sealing gasket (8.2), and then enters the exhaust valve body space (7.5) through the vent hole (10.2.1) on the surrounding wall (10.2) on the exhaust check valve (7.1), and then passes through the through hole (9.1) at the bottom of the cylinder (9). ) enters the cylinder (9). When the piston (4) moves downward, the gas in the cylinder is compressed and the air pressure increases. Under the action of the air pressure difference, the exhaust check valve (7.1) is closed and the filling check valve (6.1) is opened. The gas drawn into the cylinder (9) is pressed downward by the piston (4) and enters the device housing through the through hole (9.1) at the bottom of the cylinder (9), the filling valve body space (6.5), and the vent hole (10.2.1) on the surrounding wall (10.2) on the filling check valve (6.1) in sequence, and is discharged into the atmosphere from the gap (1.1) on the device housing. After the gas in the bottle is reduced, the remaining air in the wine bottle is reduced, which reduces the oxidation rate of the remaining wine in the bottle. In addition, the exhaust check valve at the bottle mouth has the function of sealing the bottle mouth, which can prevent the atmosphere from entering the wine bottle.

[0027] If it is necessary to add gas into the sparkling wine bottle, the screw cap (11) is rotated to drive the knob (8.1) to rotate, so that the device enters the gas filling state: after the knob (8.1) is rotated to a certain angle, the protrusion (8.4) on the knob (8.1) is engaged with the concave position (10.3) in the valve seat (10) corresponding to the gas filling sealing space (6.2), so that the sealing gasket (8.2) is aligned with the gas filling check valve (6.1) and the surrounding wall (10.3) where the gas filling check valve (6.1) is located is closed. .2), at this time, the hose (5.1) rotates along with the air nozzle hard tube (5.2) on the rotary cover (11) and the knob hard tube (8.5) on the knob (8.1) and connects the bottom through hole (9.1) of the cylinder (9), the air filling valve body space (6.5) and the air filling sealing space (6.2), the air channel (8.2.1) on the sealing gasket (8.2), the knob hard tube (8.5), the hose (5.1) and the air nozzle hard tube (5.2) to form a gas channel.

[0028] Afterwards, the screw cap (11) is placed on the bottle stopper with the gas filling check valve at the mouth of the wine bottle, and the gas filling mechanism cooperates with the gas filling check valve placed at the mouth of the sparkling wine bottle to fill the sparkling wine bottle with gas. In this gas filling state, the motor (2.2) is started, the worm (3.1) and the worm wheel (3.2) move, and the transmission connecting rod (3.4) drives the piston (4) to do reciprocating motion. When the piston (4) moves from top to bottom, the gas in the cylinder (9) is compressed and the gas pressure increases, and the gas flows from the cylinder (9) into the wine bottle through the gas channel formed between the components.

[0029] When the piston (4) moves upward, the air pressure in the cylinder (9) decreases. Under the action of the air pressure difference, the air extraction check valve (7.1) opens and the air filling check valve (6.1) closes. The gas in the atmosphere passes through the gap (1.1) between the device shells and the vent hole (10.2.1) on the surrounding wall (10.2) on the air extraction check valve (7.1) into the air extraction valve body space (7.5), and then passes through the through hole (9.1) at the bottom of the cylinder (9) into the cylinder (9). When the piston (4) moves downward, the gas in the cylinder is compressed to increase the air pressure. Under the action of the air pressure difference, the gas in the cylinder (9) is compressed. In this case, the gas filling check valve (6.1) is opened, the gas extraction check valve (7.1) is closed, and the gas in the cylinder (9) enters the gas filling sealing space (6.2) through the through hole (9.1) at the bottom of the cylinder (9), the gas filling valve body space (6.5), and the vent hole (10.2.1) on the surrounding wall (10.2) on the gas filling check valve (6.1), and then passes through the air channel (8.2.1) on the sealing pad (8.2), the knob hard tube (8.5), the hose (5.1), the screw cap gas nozzle (5.2), and the gas filling check valve at the wine bottle mouth, and finally enters the wine bottle. After gas is added to the sparkling wine bottle, the gas filling check valve at the wine bottle mouth seals the wine bottle mouth, so that a certain pressure can be maintained in the wine bottle.

[0030] See Figure 2 , 3, 4, 5. It also includes a pressure relief device (12), which includes a compression spring (12.1) and a washer screw (12.2), the cylinder (8.3) on the knob (8.1) is inserted into the interior of the compression spring (12.1), the washer screw (12.2) is inserted into the bottom of the column (10.1), and one end of the compression spring (12.1) is pressed on the washer of the washer screw (12.2), and the other end of the compression spring (12.1) is pressed on the washer of the washer screw (12.2). When the bottle is filled with gas, if the air pressure is too high, the air pressure between the valve seat (10) and the knob (8.1) increases, and the air pressure acts on the knob (8.1), so that the knob (8.1) can compress the compression spring (12.1), so that the knob (8.1) is separated from the valve seat (10), and a gap is formed between the knob (8.1) and the valve seat (10), so that the gas overflows from the gap, thereby achieving the purpose of pressure relief.
