Description

Technical Field

[0001] This utility model relates to the field of wine utensils technology, and in particular to a decanter for warming wine. Background Technology

[0002] With more and more people drinking wine these days, it's common practice to decant it before drinking to improve its flavor. Decanting typically involves pouring the wine into a vessel with a large opening and ample space, allowing it to come into contact with air over a wide area. After a period of time, the wine has decanted. During this process, shaking the wine helps it rise to the surface, promoting oxidation and accelerating the oxidation of tannins that have been stored under high pressure for a long time.

[0003] To accelerate the decanting process, existing decanting devices use an air pump to introduce oxygen-containing gas from the bottom of the container into the wine through an air intake mechanism, making the decanting process simpler and faster. However, the air intake mechanism of some current decanting devices is quite complex, making production and assembly more troublesome, which has a certain impact on the user experience.

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] like Figures 1 to 8 As shown in the figure, this is the first embodiment of the present invention, a decanter for warming wine, including a container 1, an air inlet structure 2 at the bottom of the container 1, and an air inlet one-way valve 3 sealed at the air inlet structure 2. The one-way inlet valve 3 includes a one-way inlet 301 and a mounting part 302. The one-way inlet valve 3 is sealed at the bottom of the container 1 through the mounting part 302. The one-way inlet 301 is configured to allow gas to pass through in one direction and prevent liquid from passing through.

[0019] Specifically, the intake check valve 3 includes an intake passage 304 and a duckbill-shaped check valve 303 with a pressure-receiving surface 306, and the one-way intake port 301 is located at the top of the duckbill-shaped check valve 303. A cover tube 202 is provided on both sides of the vent hole. A duckbill-shaped one-way valve 303 passes through the vent hole and is placed inside the container 1. The mounting part 302 is located at the tail end of the duckbill-shaped one-way valve 303 and is tightly fitted with the inner wall of the cover tube 202 on both sides to form a sealed connection. The cover tube 202 and the duckbill-shaped one-way valve 303 are located at the bottom of the container 1. When liquid is poured into the container 1, the height of the top of the cover tube 202 and the duckbill-shaped one-way valve 303 is lower than the liquid level in the container 1, so that oxygen can be directly delivered to the liquid and speed up the decanting process.

[0020] Furthermore, such as Figures 1 to 3 As shown, the cover tube 202 protrudes into the container 1 to form a channel 203. The air inlet one-way valve 3 is sealed in the channel 203, and the cover tube 202 protrudes into the container 1 to form an inverted U-shaped cover tube 204. The inverted U-shaped cover tube 204 is provided with a through hole 205 communicating with the inside of the container 1. The air inlet one-way valve 3 is sealed in the channel 203 of the inverted U-shaped cover tube 204. The through hole 205 is located on the upper side of the mounting part 302 in the inverted U-shaped cover tube 204. There can be one through hole 205, which can be located on the top or side of the cover tube 204, and can be groove-shaped or circular.

[0021] The through holes 205 can also be provided as at least two and evenly distributed on the tube body of the inverted U-shaped cover tube 204, and can be located on the top or side of the cover tube 204, and can be as follows: Figure 1 and Figure 2 As shown, the transverse groove structure is provided on the side wall of the cover tube 204, or as... Figure 3 As shown, the arc-shaped structure that diffuses from the inside out on the side wall of the cover tube 204 can be arranged in a ring on the wall of the inverted U-shaped cover tube 204. By increasing the number of ventilation holes and releasing oxygen in 360 degrees, the liquid in container 1 is mixed with oxygen more evenly, achieving a better decanting effect and greatly shortening the decanting time.

[0022] Meanwhile, an internal thread can be provided inside the cover tube 202, and an external thread can be provided outside the mounting part 302. The intake one-way valve 3 is threadedly connected to the cover tube 202. Alternatively, the intake one-way valve 3 can be fused into the cover tube 202, or the intake one-way valve 3 can be snapped into the cover tube 202. There are various connection methods, making it more convenient to use. Sealing ribs can also be provided outside the mounting part 302 to make the connection between the intake one-way valve 3 and the wall of the cover tube 202 tighter, while also ensuring a seal.

[0023] Furthermore, the lower end of the mounting part 302 is provided with an outwardly protruding protrusion structure 305, and the lower end of the cover tube 202 is provided with a positioning recess 206 that matches the protrusion structure 305, so that the air intake one-way valve 3 can be better embedded in the air intake structure 2 installed at the bottom of the container 1.

[0024] Its air intake one-way valve 3 is preferably made of silicone material, which fits better with the cover tube 202 and prevents water and air leakage.

[0025] Furthermore, a base 4 is provided on the lower side of the one-way air inlet valve 3, and an air supply device 5 is provided inside the base 4. The air supply device 5 includes an air supply port 501 and an air supply channel 502. The air supply port 501 corresponds to the one-way air inlet 301. The lower surface of the mounting part 302 is in contact with the outer side of the air supply channel 502 to ensure that the one-way air inlet valve 3 and the air supply port 501 form a sealed connection. A recessed positioning structure 6 is provided in the middle of the base 4. The air supply port 501 and the air supply channel 502 are located in the center of the recessed positioning structure 6. The mounting part 302 is set at the bottom of the container 1 and forms a protrusion 305 that matches the recessed positioning structure 6. The connection between the container 1 and the base 4 is positioned by the protrusion 305 and the recessed positioning structure 6.

[0026] When the duckbill-shaped one-way valve 303 is placed inside the cover tube 202, the one-way air inlet 301 is naturally closed. When the air supply port 501 and the air supply channel 502 supply air, the air pressure in the air inlet channel 304 gradually increases and becomes greater than the gas pressure in the container 1, causing the one-way air inlet 301 to open and allowing the gas in the air inlet channel 304 to enter the cover tube 202 through the one-way air inlet 301, and to come into contact with the liquid in the container 1 cavity through the through hole 205. When the air supply ends, the air pressure in the air inlet channel 304 returns to balance with the gas in the container 1, and the liquid in the cover tube 202 forms a downward and inward pressure on the pressure-receiving surface 306 of the duckbill-shaped one-way valve 303. At this time, the one-way air inlet 301 at the top closes quickly under the pressure of the pressure-receiving surface 306, effectively preventing the liquid in the container 1 cavity from leaking through the one-way air inlet 301.

[0027] The pressure-bearing surface 306 can be set as two and symmetrically arranged on the upper end of the duckbill-shaped one-way valve 303.

[0028] Even better, a waterproof and breathable membrane can also be installed at the through-hole 205. This waterproof and breathable membrane is a new type of material whose main function is to allow air and water vapor to pass freely while ensuring waterproofing, thus achieving a breathable effect. By adopting the above structure, without affecting airflow, the waterproof and breathable membrane creates a partition cavity within the channel 203 of the inverted U-shaped cover tube 204. When the inlet check valve 3 is disconnected from the container 1, the liquid inside the container 1 will not leak out through the through-hole 205, keeping the inside of the inverted U-shaped cover tube 204 dry and preventing leakage. This extends the service life of the inlet check valve 3 to a certain extent and is applicable to the disassembly and reassembly of the inlet check valve 3 and the container 1. The waterproof and breathable membrane can be directly embedded into the through-hole 205 during the production of the container 1, or attached to either side of the through-hole 205.

[0029] When a waterproof and breathable membrane is installed at the through hole 205, the one-way air inlet 301 will be closed under natural conditions or when the air supply ends.

[0030] Furthermore, its one-way air inlet 301 can also be a slit. Under normal circumstances, the slit is in a closed state. When the airflow passes through the one-way air inlet 301 from the outside to the inside, the slit is in a closed state. When the air supply port 501 and the air supply channel 502 supply air, the air pressure in the air intake channel 304 gradually increases and becomes greater than the gas pressure in the container 1, causing the slit to open and allowing the gas in the air intake channel 304 to enter the cavity of the container 1 through the slit and come into contact with the liquid. When the air supply ends, the air pressure in the air intake channel 304 returns to equilibrium with the gas in the container 1, and the slit closes quickly, effectively preventing the liquid in the cavity of the container 1 from leaking through the slit.

[0031] The gas supply equipment 5 also includes an oxygen pump 8 and an air intake filter chamber 9. The air intake filter chamber is equipped with activated carbon filter cotton. This filtration function can prevent dust and odors from contaminating the wine and ensure that the original basic taste of the wine is not affected.

[0032] Since the decanting process is actually the oxidation of tannins in wine, it needs to be in full contact with oxygen in the air. When the oxygen pump 8 is working, air is drawn into the oxygen pump 8 through the air inlet of the air supply device 5 and the activated carbon filter cotton in the air intake filter chamber 9. The air is then pumped into the wine in the container 1 through the air supply channel 502, the air supply port 501, the duckbill-shaped one-way valve 303, and the one-way air inlet 301, so that the oxygen in the air reacts with the wine to improve the taste of the wine.

[0033] Newly made red wines contain a lot of tannins. Using a decanter softens the tannins through oxidation with oxygen, eliminating most of the acidity and astringency, and greatly improving the taste. It also reduces the residual flavors from winemaking equipment such as corks and pressing tools that may have been present in the wine during the brewing and aging process.

[0034] Due to the brewing process, baijiu will have residual phenolic compounds and furfural in the liquor, which will manifest as bitterness, spiciness and sourness in the taste. Through large-scale reaction with oxygen microbubbles and evaporation, the substances that affect the taste, such as fusel alcohols and tannins, can be reduced, ultimately improving the taste of the liquor.

[0035] Furthermore, such as Figure 6 and Figure 8 As shown, a heating plate 7 is embedded in the base 4. The heating plate 7 is separated from the container 1 by the upper partition of the base 4. The lower surface of the container 1 is in contact with the upper surface of the upper partition of the base 4. The heating plate 7 is placed under the upper partition of the base 4. The heat from the heating plate 7 is transferred to the lower surface of the container 1 through the upper partition of the base 4, thereby heating the solution in the container 1.

[0036] Its heating plate 7 can be heated by heating wires, and then conducted to the lower surface of container 1 through heating plate 7 to heat the liquor in container 1. Especially in cold winter, the appropriate temperature can improve the taste of drinking, avoid the stimulation of large temperature difference, allow the smooth muscle of blood vessels to relax appropriately, relieve the tension of blood vessels, and expel methanol in liquor due to the increase in temperature, thus improving the taste. It can also slightly reduce the alcohol content and reduce the damage of alcohol to the body.

[0037] like Figure 9 As shown in the figure, this is a second embodiment of the container 1 and the one-way valve 3 of this utility model. A wine decanter for warming wine includes a container 1. The bottom of the container 1 is provided with an air inlet structure 2. An air inlet valve 3 is sealed at the air inlet structure 2. The one-way valve 3 includes a one-way air inlet 301 and a mounting part 302. The one-way valve 3 is sealed at the bottom of the container 1 through the mounting part 302. The one-way air inlet 301 is configured to allow gas to pass through in one direction and prevent liquid from passing through.

[0038] Specifically, the intake check valve 3 includes an intake passage 304 and a duckbill-shaped check valve 303 with a pressure-receiving surface 306, and the one-way intake port 301 is located at the top of the duckbill-shaped check valve 303. A vent is flanked by two cover tubes 202, which are at the same height as the bottom wall of container 1. A duckbill-shaped one-way valve 303 passes through the vent and is placed inside container 1. The mounting part 302 is located at the tail end of the duckbill-shaped one-way valve 303 and is tightly fitted to the inner wall of the cover tube 202 on both sides to form a sealed connection. Alternatively, a sealing rib can be provided on the outside of the mounting part 302 to make the connection between the air inlet one-way valve 3 and the wall of the cover tube 202 tighter, while also ensuring a seal. When liquid is poured into container 1, the height of the cover tube 202 and the top of the duckbill-shaped one-way valve 303 is lower than the liquid level in container 1, allowing oxygen to be directly delivered into the liquid and accelerating the decanting process.

[0039] Furthermore, the lower end of the mounting part 302 is provided with an outwardly protruding protrusion structure 305, and the lower end of the cover tube 202 is provided with a positioning recess 206 that matches the protrusion structure 305, so that the air intake one-way valve 3 can be better embedded in the air intake structure 2 installed at the bottom of the container 1.

[0040] Its air intake one-way valve 3 is preferably made of silicone material, which fits better with the cover tube 202 at the vent hole to prevent water and air leakage.

[0041] A base 4 is provided on the lower side of the one-way air inlet valve 3. An air supply device 5 is provided inside the base 4. The air supply device 5 includes an air supply port 501 and an air supply channel 502. The air supply port 501 corresponds to the one-way air inlet 301. The lower surface of the mounting part 302 is attached to the outside of the air supply channel 502 to ensure that the one-way air inlet valve 3 and the air supply port 501 form a sealed connection. A recessed positioning structure 6 is provided in the middle of the base 4. The air supply port 501 and the air supply channel 502 are located in the center of the recessed positioning structure 6. The mounting part 302 is set at the bottom of the container 1 and forms a protrusion 305 that matches the recessed positioning structure 6. The connection between the container 1 and the base 4 is positioned by the protrusion 305 and the recessed positioning structure 6.

[0042] When the duckbill-shaped one-way valve 303 is placed inside the container 1, the one-way air inlet 301 is naturally closed. When the air supply port 501 and the air supply channel 502 supply air, the air pressure in the air inlet channel 304 gradually increases and becomes greater than the gas pressure in the container 1, causing the one-way air inlet 301 to open and allowing the gas in the air inlet channel 304 to enter the container 1 through the one-way air inlet 301 and come into contact with the liquid inside the container 1. When the air supply ends, the air pressure in the air inlet channel 304 returns to equilibrium with the gas in the container 1. The liquid inside the container 1 exerts a downward and inward pressure on the pressure-bearing surface 306 of the duckbill-shaped one-way valve 303. At this time, the one-way air inlet 301 at the top closes quickly under the pressure of the pressure-bearing surfaces 306 on both sides, effectively preventing the liquid inside the container 1 from leaking through the one-way air inlet 301.

[0043] The pressure-bearing surface 306 can be set as two and symmetrically arranged on the upper end of the duckbill-shaped one-way valve 303.

[0044] Furthermore, its one-way air inlet 301 can also be a slit.

[0045] like Figure 10 and Figure 11 As shown in the figure, this figure represents the third and fourth embodiments of the container 1 and the one-way valve 3 of this utility model. The container 1 includes an air intake structure 2 at the bottom of the container 1, and an air intake one-way valve 3 is sealed at the air intake structure 2. The air intake one-way valve 3 includes a one-way air inlet 301 and a mounting part 302. The air intake one-way valve 3 is sealed at the bottom of the container 1 through the mounting part 302. The one-way air inlet 301 is configured to allow gas to pass through in one direction and prevent liquid from passing through.

[0046] Specifically, the intake check valve 3 includes an intake passage 304 and a duckbill-shaped check valve 303 with a pressure-receiving surface 306, and the one-way intake port 301 is located at the top of the duckbill-shaped check valve 303. A vent is flanked by two hoods 202, which protrude into the container 1 to form a channel 203. An air inlet one-way valve 3 is sealed within the channel 203, and a duckbill-shaped one-way valve 303 is placed inside the container 1. An mounting part 302 is located at the tail end of the duckbill-shaped one-way valve 303, and its two sides are tightly fitted to the inner wall of the hood 202 to form a sealed connection. Alternatively, a sealing rib can be provided on the outside of the mounting part 302 to make the connection between the air inlet one-way valve 3 and the wall of the hood 202 even tighter, while also ensuring a seal. When liquid is poured into the container 1, the height of the hood 202 and the top of the duckbill-shaped one-way valve 303 is lower than the liquid level in the container 1, allowing oxygen to be directly delivered into the liquid and accelerating the decanting process.

[0047] Furthermore, the lower end of the mounting part 302 is provided with an outwardly protruding protrusion structure 305, and the lower end of the cover tube 202 is provided with a positioning recess 206 that matches the protrusion structure 305, so that the air intake one-way valve 3 can be better embedded in the air intake structure 2 installed at the bottom of the container 1.

[0048] like Figure 8 As shown, the protruding cover tube 202 can be cylindrical, such as... Figure 9 As shown, the protruding cover tube 202 can also be conical.

[0049] Its air intake one-way valve 3 is preferably made of silicone material, which fits better with the cover tube 202 and prevents water and air leakage.

[0050] A base 4 is provided on the lower side of the one-way air inlet valve 3. An air supply device 5 is provided inside the base 4. The air supply device 5 includes an air supply port 501 and an air supply channel 502. The air supply port 501 corresponds to the one-way air inlet 301. The lower surface of the mounting part 302 is attached to the outside of the air supply channel 502 to ensure that the one-way air inlet valve 3 and the air supply port 501 form a sealed connection. A recessed positioning structure 6 is provided in the middle of the base 4. The air supply port 501 and the air supply channel 502 are located in the center of the recessed positioning structure 6. The mounting part 302 is set at the bottom of the container 1 and forms a protrusion 305 that matches the recessed positioning structure 6. The connection between the container 1 and the base 4 is positioned by the protrusion 305 and the recessed positioning structure 6.

[0051] When the duckbill-shaped one-way valve 303 is placed inside the container 1, the one-way air inlet 301 is naturally closed. When the air supply port 501 and the air supply channel 502 supply air, the air pressure in the air inlet channel 304 gradually increases and becomes greater than the gas pressure in the container 1, causing the one-way air inlet 301 to open and allowing the gas in the air inlet channel 304 to enter the container 1 through the one-way air inlet 301 and come into contact with the liquid inside the container 1. When the air supply ends, the air pressure in the air inlet channel 304 returns to equilibrium with the gas in the container 1. The liquid inside the container 1 exerts a downward and inward pressure on the pressure-bearing surface 306 of the duckbill-shaped one-way valve 303. At this time, the one-way air inlet 301 at the top closes quickly under the pressure of the pressure-bearing surfaces 306 on both sides, effectively preventing the liquid inside the container 1 from leaking through the one-way air inlet 301.

[0052] The pressure-bearing surface 306 can be set as two and symmetrically arranged on the upper end of the duckbill-shaped one-way valve 303.

[0053] Furthermore, its one-way air inlet 301 can also be a slit.

[0054] This invention features an air inlet check valve 3 installed at the bottom of container 1 via mounting part 302, connecting the vent hole and the one-way air inlet 301. The one-way air inlet 301 allows gas from the outside of container 1 to enter while preventing liquid from flowing out of container 1, ensuring that the airflow can fully enter the liquid storage chamber. A cover tube 202 is provided at the bottom of container 1, which is detachably connected to the air inlet check valve 3, facilitating user cleaning of the venting part and preventing bacterial growth after long-term use. The air inlet check valve 3 has a simple structure and can also be welded to container 1 or directly generated.

[0055] Its one-way air inlet valve 3 can be connected to the container 1 in different ways. The air vent, the one-way air inlet valve 3, and the air supply port 501 on the base 4 can also be set to multiple, which can adapt to a variety of alcoholic beverages. Different decanting times and warming times can be selected according to different types of alcoholic beverages. It has more comprehensive functions and is more convenient to use.

[0056] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
