Description

Technical Field

[0001] This invention belongs to the field of wine preservation technology, specifically relating to a wine preservation machine and its preservation method. Background Technology

[0002] Wine preservation involves the oxidation process of wine and its impact on quality. Once opened, wine easily comes into contact with oxygen in the air, leading to oxidation, which affects the wine's flavor and aroma, and diminishes the drinking experience. Therefore, extending the shelf life of opened wine has become a key focus for wine enthusiasts and producers.

[0003] Wine oxidation is typically slowed by filling the bottle with inert gas to isolate it from air. However, existing devices often leave wine residue on the inner wall of the dispensing pipe after dispensing. If not cleaned promptly, this not only results in waste, but the residual wine, exposed to air for a long time, may also breed bacteria, affecting the hygiene and safety of subsequent dispensing. Furthermore, it is difficult to ensure that the dispensing port and the gas filling port open and close synchronously and reliably during the dispensing process. Therefore, those skilled in the art have provided a wine preservation machine and its preservation method to solve the problems mentioned in the background art. Summary of the Invention

[0014] A method for preserving wine, comprising the following steps: S1. Initial preparation and connection: Fill the storage bottle with the wine that needs to be preserved, and set the heating temperature of the electric heating tank according to the type of wine through the controller. Then, insert the sealing plug into the storage bottle, and at the same time, thread the second installation cap to the storage bottle. Meanwhile, connect the gas tank containing inert gas and the water pipe to the gas inlet pipe and water inlet pipe respectively. S2. Wine Dispensing: The servo motor is controlled by the main control module. The servo motor drives the second worm gear to rotate, so that the first worm and the second worm gear can rotate synchronously. At this time, the second worm gear drives the second worm to rotate, and the first worm will drive the first worm gear to rotate. As the second worm rotates, it will drive the shaft to rotate, so that the through holes at the gas filling port and the discharge port are open. At the same time, the first worm gear drives the lead screw to rotate, so that the slider on the side wall of the lead screw can drive the reversing block to slide in the square tube. This allows the through hole in the middle of the reversing block to connect the air inlet pipe and the connecting pipe, so that gas can flow from the gas storage tank into the connecting pipe, thereby delivering inert gas to the gas filling port. The inert gas is poured into the storage bottle through the discharge port. Under the action of air pressure, the wine can be forced into the discharge port through the air guide hole and sprayed out from the discharge pipe to realize the wine dispensing operation. S3. Anti-oxidation: After the wine is extracted, the servo motor is controlled to rotate in reverse. The second worm gear drives the shaft to rotate in reverse, and the first worm wheel drives the lead screw to rotate in reverse. This allows the ball valve to block the outlet and the gas filling port. At the same time, the reversing block can connect the water inlet pipe and the rinsing pipe. Since inert gas is injected into the storage bottle, and the density of inert gas is greater than that of air, air can be separated from the wine. The one-way sealing module blocks the air guide hole and the discharge port, which can initially prevent external air from entering. At the same time, the ball valve blocks the outlet and the gas filling port, further preventing air from entering and achieving the preservation treatment of the wine. S4. Pipeline cleaning: After the reversing block connects the inlet pipe and the flushing pipe, the pump can be turned on to draw water through the inlet pipe and enter the outlet pipe through the flushing pipe. This can clean the inner wall of the outlet pipe after the wine is taken out, and prevent wine residue.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, by setting up a discharge device and a power device, a servo motor drives the second worm gear to rotate, so that the first worm and the second worm gear can rotate synchronously. At this time, the second worm gear drives the second worm to rotate, and the first worm will drive the first worm gear to rotate. As the second worm rotates, it will drive the rotating shaft to rotate, so that the two through holes at the gas filling port and the discharge port are in the open state. Controlling the servo motor to rotate in the opposite direction can drive the second worm to rotate the rotating shaft in the opposite direction, so that the ball valve can block the discharge port and the gas filling port. Since inert gas is injected into the storage bottle, and the density of inert gas is greater than that of air, it can separate air from wine, effectively realizing the preservation of wine, while providing power for wine extraction.

[0016] 2. In this invention, by setting a reversing device and a connecting device, the first worm gear drives the lead screw to rotate, so that the slider on the side wall of the lead screw can drive the reversing block to slide in the square tube. This allows the through hole in the middle of the reversing block to connect the air inlet pipe and the connecting pipe, allowing gas to flow from the gas storage tank into the connecting pipe, thereby supplying inert gas to the gas filling port. The inert gas is then poured into the storage bottle through the discharge port. Under the action of air pressure, the wine is forced through the air guide hole into the discharge port and sprayed out from the discharge pipe, achieving... During the wine dispensing operation, the reversing block connects the water inlet pipe and the rinsing pipe. The one-way sealing module blocks the air vent and discharge port, which initially prevents external air from entering. At the same time, the ball valve flap blocks the discharge port and the air filling port, further preventing air from entering and achieving the preservation treatment of the wine. After the reversing block connects the water inlet pipe and the rinsing pipe, the pump can be turned on to draw water through the water inlet pipe and enter the discharge pipe through the rinsing pipe. This can clean the inner wall of the discharge pipe after the wine is dispensed, avoiding wine residue. Attached Figure Description

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wine preservation machine includes a housing 13. A discharge device 1 is installed through the top of the inner wall of the housing 13. A storage device 5 is installed on one side of the top of the inner wall of the housing 13. A reversing device 3 is installed on one side of the top of the discharge device 1. A power device 2 is installed at the front end of the discharge device 1. A connecting device 4 that cooperates with the storage device 5 is installed at the bottom end of the power device 2. A main control module 7 is fixedly connected to one side of the top of the housing 13. The main control module 7 is prior art and is used to control the operating status of the equipment. Cabinet doors 10 are hinged to both sides of the front end of the housing 13.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 As shown, the discharge device 1 includes a discharge pipe 101 that is fixedly penetrated through the top of the inner wall of the housing 13. A fixing block 102 is provided at the bottom of the discharge pipe 101. A wastewater tray 6 that cooperates with one end of the discharge pipe 101 is fixedly connected to one side of the top of the housing 13. A discharge port 104 that is fixedly connected to the other end of the discharge pipe 101 is provided through one side of the top of the fixing block 102. An air inlet 103 is provided through the other side of the top of the fixing block 102. A limiting ring 107 that is fixedly connected to the top of the fixing block 102 and communicates with the discharge port 104 and the air inlet 103 respectively is fixedly connected to the top of the fixing block 102. The limiting ring 107 is provided at the bottom of the discharge port 104 and the air inlet 103. The limiting ring 107 can improve the stability of the discharge device 1 and the connecting device 4 during installation and avoid misalignment during installation.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 As shown, the inner walls of the discharge pipe 101 and the air inlet 103 are respectively rotatably sealed with spherical valve discs 105. The two spherical valve discs 105 are fixedly connected, and one of the spherical valve discs 105 is fixedly connected to a rotating shaft 106 that rotatably passes through the side wall of the fixed block 102. As the power device 2 drives the rotating shaft 106 to rotate, the two through holes of the air inlet 103 and the discharge port 104 are in the open state.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 11As shown, the power unit 2 includes a protective cover 201 fixedly connected to the front end of the fixed block 102. A second worm gear 206 is rotatably connected to the front end of the fixed block 102 and fixedly sleeved on the other end of the rotating shaft 106. A mounting bracket 207 is fixedly connected to the front end of the fixed block 102. A servo motor 202 is fixedly connected to the side wall of the mounting bracket 207. A second worm 205 is fixedly connected to the output end of the servo motor 202 and rotatably passes through the inner wall of the mounting bracket 207. The second worm 205 meshes with the second worm gear 206. A first worm 204 is fixedly connected to the other end of the second worm 205. A first worm gear 203 that cooperates with the reversing device 3 meshes with the side wall of the first worm gear 204. The servo motor 202 drives the second worm gear 205 to rotate, so that the first worm gear 204 and the second worm gear 205 can rotate synchronously. At this time, the second worm gear 205 drives the second worm gear 206 to rotate, and the first worm gear 204 drives the first worm gear 203 to rotate.

[0024] like Figure 1 - Figure 10 As shown, the reversing device 3 includes a square tube 301 fixedly connected to one side of the top of the fixed block 102. A reversing block 307 is slidably sealed on the inner wall of the square tube 301. A positioning frame 308 is fixedly connected to the front side of the bottom end of the square tube 301. A lead screw 310 rotatably passes through the inner wall of the positioning frame 308, and one end of the lead screw 310 is fixedly connected to the middle of the first worm gear 203. A slider 309, which is fixedly connected to the middle of the bottom end of the reversing block 307, is threaded onto the side wall of the lead screw 310. A connecting pipe 305, which is fixedly connected to the air inlet 103, is fixedly connected to one side of the square tube 301. A flushing pipe 306, which is connected to the discharge pipe 101, is fixedly connected to one side of the square tube 301. A pump 304 is fixedly connected to the other side of the square tube 301. A water inlet pipe 303 is fixedly connected to the input end of the pump 304. A hole is provided in the middle of the reversing block 307. The air inlet pipe 302 can be connected to the connecting pipe 305 or the water inlet pipe 303 can be connected to the flushing pipe 306 through the hole, so as to realize the switching between cleaning and gas injection. And through the synchronous drive of the power device 2, when the ball valve 105 is in the connected state, the connecting pipe 305 is connected to the air inlet pipe 302 to inject inert gas into the storage device 5. When the ball valve 105 is closed, the water inlet pipe 303 is connected to the flushing pipe 306 to clean the discharge pipe 101.

[0025] like Figure 1 - Figure 10As shown, an air inlet pipe 302 is fixedly connected to the other side wall of the square tube 301. One end of the air inlet pipe 302 is connected to a gas storage tank containing inert gas. The inert gas isolates the wine from the air, preventing oxidation. A first sealing ball 312 and a second sealing ball 314 are installed in the air inlet pipe 302. When the hole in the reversing block 307 is connected to the air inlet pipe 302, the second sealing ball 314, under the elastic force of the first spring 313, causes the first sealing ball 312 to release its blockage of the air inlet pipe 302. When the hole in the reversing block 307 is removed, the side wall of the reversing block 307 exerts pressure on the second sealing ball 314, causing the first sealing ball 312 to seal the air inlet pipe 302, preventing gas leakage and allowing air to enter. A limiting frame 311 is fixedly connected to the middle of the inner wall of the pipe 302. A connecting rod 315 slides through the middle of the limiting frame 311. A second sealing ball 314 is fixedly connected to one end of the connecting rod 315, and a first sealing ball 312 is fixedly connected to the other end of the second sealing ball 314. A first spring 313 is sleeved on the side wall of the connecting rod 315 and fixedly connected to the side wall of the second sealing ball 314. The first worm gear 203 drives the lead screw 310 to rotate, so that the slider 309 on the side wall of the lead screw 310 can drive the reversing block 307 to slide in the square tube 301. Thus, the through hole in the middle of the reversing block 307 can connect the air inlet pipe 302 and the connecting pipe 305, so that gas can flow from the gas storage tank into the connecting pipe 305, thereby delivering inert gas to the gas filling port 103.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 and Figure 13As shown, the connecting device 4 includes a first mounting cover 401 threaded onto the bottom end of the fixing block 102. A mounting sealing plug 405 is provided through the bottom end of the first mounting cover 401. Several rubber rings 406 are fixedly fitted onto the side wall of the mounting sealing plug 405. An air guide hole 407 is provided through one side of the top end of the mounting sealing plug 405, and a discharge port 403 is provided through the other side wall of the top end of the mounting sealing plug 405. One-way sealing modules 404 are respectively fitted into the inner walls of the air guide hole 407 and the discharge port 403, and the two one-way sealing modules 404 are installed in opposite directions. The first mounting cover 401... The bottom end of the first mounting cover 401 is rotatably connected to a second mounting cover 402 that is sleeved on the side wall of the mounting sealing plug 405. The first mounting cover 401 can connect the discharge device 1 to the mounting sealing plug 405, so that the whole device can be disassembled and cleaned after a period of use, thus improving the preservation effect. At the same time, the bottom end of the first mounting cover 401 is rotatably provided with the second mounting cover 402. After the mounting sealing plug 405 is inserted into the storage device 5, the rubber ring 406 and the inside of the storage device 5 form a sealed environment. The second mounting cover 402 can further improve the sealing effect.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 and Figure 13 As shown, the one-way sealing module 404 includes a positioning ring 4044 fixedly connected to the inner wall of the discharge port 403. A through frame 4045 is fixedly connected to the top of the positioning ring 4044. A fixing rod 4042 slides through the middle of the through frame 4045. A one-way sealing plug 4041 is fixedly connected to the top of the fixing rod 4042. A second spring 4043 is sleeved on the side wall of the fixing rod 4042 and fixedly connected to the bottom end of the one-way sealing plug 4041. At the air guide hole 404... One-way sealing modules 404 are respectively provided in the air inlet 7 and the discharge port 403, and the one-way sealing modules 404 in the air guide hole 407 and the discharge port 403 are placed in opposite directions to form a one-way flow path. This allows the gas to enter the storage device 5 by pushing open the one-way sealing plug 4041 when it enters from the air inlet 103, and press the wine into the air guide hole 407, and push open the one-way sealing plug 4041 in the air guide hole 407, so that the wine is sprayed out through the discharge pipe 101.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the storage device 5 includes an electric heating barrel 501 fixedly connected to one side of the top of the inner wall of the housing 13. A controller 502 is fixedly connected to the front end of the electric heating barrel 501. A storage bottle 503 that cooperates with the sealing plug 405 is provided on the inner wall of the electric heating barrel 501. The top of the storage bottle 503 is threadedly connected to the second mounting cap 402. A storage box 15 is fixedly connected to one side of the inner wall of the gas inlet 103. The storage bottle 503 is filled with wine that needs to be preserved. The heating temperature of the electric heating barrel 501 is set by the controller 502 according to the type of wine.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a ventilation pipe 8 is fixedly connected to one side of the box 13. A fan 12 is installed on the inner wall of the ventilation pipe 8. A first filter 9 is fixedly connected to one end of the ventilation pipe 8. A second filter 14 is fixedly passed through the other side of the box 13. Several wiring holes 11 are opened at the bottom of the other side of the box 13. The ventilation pipe 8 is installed on the side wall of the box 13, and the fan 12 is installed on the inner wall of the ventilation pipe 8. With the second filter 14, external air can be drawn in by the fan 12 through the ventilation pipe 8 and discharged through the second filter 14, providing a dry and clean air environment for wine preservation.

[0030] It should be noted that, in the process of using this wine preservation machine and its preservation method, the wine to be preserved is filled into the storage bottle 503, and the heating temperature of the electric heating tank 501 is set by the controller 502 according to the type of wine. Then, the sealing plug 405 is inserted into the storage bottle 503, and the second mounting cap 402 is threadedly connected to the storage bottle 503. At the same time, the gas tank containing inert gas and the water pipe are respectively connected to the air inlet pipe 302 and the water inlet pipe 303. The servo motor 202 is controlled by the main control module 7. The servo motor 202 drives the second worm gear 205 to rotate, allowing the first worm 204 and the second worm gear 205 to rotate synchronously. At this time, the second worm gear 205 drives the second worm 206 to rotate, and the first worm 204 drives the first worm gear 203 to rotate. The rotation of the second worm 206 drives the rotating shaft 106 to rotate, opening the through holes at the air inlet 103 and the outlet 104. Simultaneously, the first worm gear 203 drives the lead screw 310 to rotate, causing the lead screw to rotate... The slider 309 on the side wall of the rod 310 can drive the reversing block 307 to slide in the square tube 301, so that the through hole in the middle of the reversing block 307 can connect the air inlet pipe 302 and the connecting pipe 305, so that gas can flow from the gas storage tank into the connecting pipe 305, thereby delivering inert gas to the gas filling port 103. The inert gas is poured into the storage bottle 503 through the discharge port 403. Under the action of air pressure, the wine can be forced into the discharge port 104 through the air guide hole 407 and sprayed out from the discharge pipe 101 to realize the wine taking operation. After the wine is extracted, the servo motor 202 is controlled to rotate in the reverse direction. The second worm gear 206 drives the rotating shaft 106 to rotate in the reverse direction, and the first worm wheel 203 drives the lead screw 310 to rotate in the reverse direction. This allows the ball valve 105 to block the discharge port 104 and the gas filling port 103. At the same time, the reversing block 307 can connect the water inlet pipe 303 and the rinsing pipe 306. Since inert gas is injected into the storage bottle 503, and the density of inert gas is greater than that of air, air can be separated from the wine. The one-way sealing module 404 blocks the air guide hole 407 and the discharge port 403, which can initially prevent the entry of external air. At the same time, the ball valve 105 blocks the discharge port 104 and the gas filling port 103, further preventing air from entering and achieving the preservation treatment of the wine.

[0031] After the reversing block 307 connects the water inlet pipe 303 and the flushing pipe 306, the pump 304 can be turned on to draw water through the water inlet pipe 303 and enter the discharge pipe 101 through the flushing pipe 306. This can clean the inner wall of the discharge pipe 101 after the wine is taken out, and prevent wine residue.

[0032] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.

10. A method for preserving wine, based on a wine preservation machine according to any one of claims 1-9, characterized in that: Includes the following steps: S1. Initial preparation and connection: Fill the storage bottle (503) with the wine that needs to be preserved, and set the heating temperature of the electric heating tank (501) according to the type of wine through the controller (502). Then, insert the sealing plug (405) into the storage bottle (503), and at the same time, thread the second mounting cap (402) to the storage bottle (503). At the same time, connect the gas tank containing inert gas and the water pipe to the air inlet pipe (302) and the water inlet pipe (303) respectively. S2, Wine Retrieval: The servo motor (202) is controlled by the main control module (7). The servo motor (202) drives the second worm gear (205) to rotate, so that the first worm (204) and the second worm gear (205) can rotate synchronously. At this time, the second worm gear (205) drives the second worm (206) to rotate, and the first worm (204) drives the first worm gear (203) to rotate. As the second worm (206) rotates, it drives the rotating shaft (106) to rotate, so that the two through holes at the gas filling port (103) and the discharge port (104) are in the open state. At the same time, the first worm gear (203) drives the screw (310) to rotate. The movement causes the slider (309) on the side wall of the lead screw (310) to drive the reversing block (307) to slide in the square tube (301), so that the through hole in the middle of the reversing block (307) can connect the air inlet pipe (302) and the connecting pipe (305), so that the gas can flow from the gas storage tank into the connecting pipe (305), thereby delivering inert gas to the gas filling port (103). The inert gas is poured into the storage bottle (503) through the discharge port (403). Under the action of air pressure, the wine can be forced into the discharge port (104) through the air guide hole (407) and sprayed out from the discharge pipe (101) to realize the wine taking operation. S3, Anti-oxidation: After the wine is extracted, the servo motor (202) is controlled to rotate in the opposite direction. The second worm (206) drives the rotating shaft (106) to rotate in the opposite direction, and the first worm wheel (203) drives the lead screw (310) to rotate in the opposite direction. This allows the ball valve (105) to block the discharge port (104) and the gas filling port (103). At the same time, the reversing block (307) can connect the water inlet pipe (303) and the rinsing pipe (306). Since the inert gas is injected into the storage bottle (503), and the density of the inert gas is greater than that of air, the air can be separated from the wine. The one-way sealing module (404) blocks the air guide hole (407) and the discharge port (403), which can initially prevent the entry of external air. At the same time, the ball valve (105) blocks the discharge port (104) and the gas filling port (103), which further prevents the entry of air and achieves the preservation treatment of the wine. S4. Pipeline cleaning: After the reversing block (307) connects the inlet pipe (303) and the flushing pipe (306), the pump (304) can be turned on to pump water through the inlet pipe (303) and enter the outlet pipe (101) through the flushing pipe (306). This can clean the inner wall of the outlet pipe (101) after the wine is taken out, and prevent wine residue.
