Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wine drinking equipment, and particularly relates to a pressure relief sealed wine spear. BACKGROUND

[0002] A wine barrel is a tool for containing wine, and a wine spear is generally arranged at the barrel opening of the wine barrel. The wine spear cooperates with a distributor to press the wine in the wine barrel out. After the distributor is connected to the wine spear, two pipelines are formed, i.e., an air inlet pipeline and a wine outlet pipeline. The air inlet pipeline is used to introduce air or high-pressure air into the wine barrel, so that the wine flows out through the wine outlet pipeline. The existing wine barrel generally comprises a barrel body and a wine bag, and a wine spear extending into the wine bag is arranged at the barrel opening of the barrel body. An elastic valve core capable of controlling the opening and closing of the wine path is movably connected in the wine spear. When wine is needed, a user installs a distributor and an air pump on the wine spear, pushes the valve core downward through the distributor, and opens the wine outlet channel in the wine spear. At this time, the user can inflate the wine barrel (between the wine barrel and the wine bag) through the air pump, so that the high-pressure air continuously presses the wine bag, and the wine in the wine bag enters the wine spear through the wine outlet channel and finally flows out of the wine spear.

[0003] In the process of daily transportation, the wine may be shaken due to transportation and sales, and gas may be generated. If the gas is not discharged in time, the barrel body and the wine bag may burst. Therefore, a safe pressure relief valve is needed to safely discharge the gas. However, the existing pressure relief structure of a wine barrel with an application number of 202220922007.9 has the following defects.

[0004] 1. Generally, it takes several days to sell a barrel of wine. During the selling process, the distributor is always connected. When the distributor is connected to the wine barrel, the mounting seat is pressed down, and the gap between the pressure relief valve one and the valve core is connected to the wine outlet connector in the distributor through the mounting seat to serve as a wine pipeline. The wine flows out of the gap between the pressure relief valve one and the valve core to the external wine pipeline. When the wine barrel is connected to the distributor, the water faucet at the end of the wine pipeline is used to control the outflow of the wine. When there is no customer to drink the wine, the water faucet is closed, and the wine pipeline is in a closed state. When the wine barrel is replaced, the distributor pipeline is in an exposed state, and the original wine pipeline is directly exposed to the air, which causes the beer in the wine pipeline to be infected with bacteria. When the wine is used, the beer flows back to the beer barrel from the external wine pipeline, causing the beer to be fermented again and generating a large amount of gas. At this time, the pressure relief valve for pressure relief in the wine bag is connected to the external wine pipeline of the distributor, so the pressure relief valve is in a static state and loses the pressure relief effect.

[0005] 2. The pressure relief valve described in this patent has poor sealing performance. The sealing end of the valve stem is conical, and the side wall is a smooth bevel. While it can achieve a sealing effect when storing wine, during transportation, especially with pressure on the pressure relief valve above the wine bag, some wine may seep into the valve stem and the side wall of the mounting seat gap. During the pressure relief process, the wine overflows from the upper surface of the valve stem and the side wall of the mounting seat gap. After contacting the air, especially in poor transportation environments, it may oxidize and contaminate the mounting seat and valve stem, and may also breed bacteria. Furthermore, since the wine inlet pipe and the pressure relief pipe are the same pipe, it will come into contact with the pressure relief gap between the mounting seat and the valve stem during the pouring process, affecting the flavor and taste of the wine.

[0029] The present invention will now be described in detail with reference to the embodiments illustrated in the drawings:

[0030] As Figs. 1-3As shown, in the present embodiment, a pressure relief sealing wine spear is provided, the wine outlet pipeline and the pressure relief pipeline of the wine spear are separated, and the gas is discharged from the pressure relief pipeline when the inner bag is relieved, and the wine outlet pipeline is used for the wine pouring and filling. The wine spear is connected to the barrel opening of the wine barrel, the wine barrel comprises a barrel body 1, the wine spear comprises an inner bag 2, an inner wine pipeline, a pressure relief pipeline and a first pressure relief valve 3, and the wine pipeline and the pressure relief pipeline are connected through the first pressure relief valve 3; the wine spear comprises a fastener 4 and a mounting seat 5, the fastener 4 is arranged on the barrel opening of the barrel body 1, and the fastener 4 is connected with the mounting seat 5 and the barrel body 1.

[0031] Further, the mounting seat 5 is internally provided with an air channel 7, the air channel 7 communicates the gap between the barrel body 1 and the inner bag 2 (the gap is used to allow the dispenser to fill the gas to increase the pressure in the barrel body 1, so as to act on the inner bag 2 to squeeze out the wine in the inner bag 2), specifically, the opening end of the inner bag is fixedly connected with the mounting portion through superplastic fusion, the opening end of the inner bag is located below the exhaust hole 8, and the mounting seat 5 is arranged on the barrel opening of the barrel body 1; the first pressure relief valve 3 is arranged in the air channel 7, the outer side of the mounting portion is further provided with a plurality of exhaust holes 8, the exhaust holes 8 are connected with the air channel 7, the plurality of exhaust holes 8 are arranged between the barrel body 1 and the inner bag, the buffer cavity 6 is connected with the air channel 7, the fastener 4 is provided with a pressure relief cavity 9, the pressure relief cavity 9 is connected with the buffer cavity 6, the second pressure relief valve 10 is arranged in the pressure relief cavity 9, the fastener 4 is provided with a pressure relief hole 11, the pressure relief hole 11 penetrates the fastener 4 and is connected with the pressure relief cavity 9, and the pressure relief cavity 9 is connected with the air pressure outside through the pressure relief hole 11.

[0032] In the present embodiment, the upper inner wall of the buffer cavity 6 is a tapered slope, the buffer cavity 6 is clamped with a sealing valve core 12, the outer side wall of the sealing valve core 12 forms an inflation gap 13 with the tapered slope, and in one embodiment, the sealing valve core 12 is clamped by a spring 19 under the elastic action; the outer edge top of the sealing valve core 12 is limitingly clamped with the upper end of the fastener 4, so as to prevent the inflation gap 13 from being communicated with the air outside; in another embodiment, the sealing valve core 12 is pressed downwardly, the spring 19 is pressed, the outer edge top of the sealing valve core 12 is not limitingly clamped with the upper end of the fastener 4, the inflation gap 13 between the two is enlarged, so that the buffer cavity 6 can be communicated with the air outside.

[0033] It is worth mentioning that the structure of the first pressure relief valve 3 is the same as that of the second pressure relief valve 10. The opening valve value of the first pressure relief valve 3 is greater than that of the second pressure relief valve 10, in order to prevent the first pressure relief valve 3 from being in an open state for a long time, in other words, when the wine is stored, the pressure between the barrel 1 and the inner bag 2 and the pressure of the pressure relief pipeline must be less than the pressure in the inner bag 2 and the wine pipeline; the wine will be jolted during transportation, and if the first pressure relief valve 3 is always in an open state, the wine in the inner bag 2 may flow into the pressure relief pipeline through the first pressure relief valve 3, and the barrel 1 needs to be cleaned regularly.

[0034] In this embodiment, the middle part of the mounting seat 5 is connected with the wine pipeline, the wine pipeline is vertically arranged inside the mounting seat 5, the infusion pipe 14 is connected with the wine pipeline in penetration, the top of the infusion pipe 14 is slidably provided with the sealing valve core 12, the upper side wall of the infusion pipe 14 is provided with the flow-through hole 15 in penetration, the middle part of the sealing valve core 12 is provided with the sliding hole, the sealing valve core 12 and the infusion pipe 14 cooperate to form the wine gap 17, and the flow-through hole 15 is connected with the wine gap 17 in penetration. In one of the embodiments, the sealing valve core 12 is limited to the top of the fastener 4 by the elastic stress of the spring 19, specifically, the top extension edge of the sliding hole is limited and clamped with the top of the infusion pipe 14, at this time, the wine gap 17 becomes very small, and the wine mainly flows out from the flow-through hole 15 to the wine gap 17 and then flows out from the top extension edge of the sliding hole or is connected with the wine pouring part of the distributor, so that the wine gap 17 becomes very small and the top extension edge of the sliding hole is in close contact with the top of the infusion pipe 14, and the wine cannot flow out to achieve the sealing effect. In another embodiment, the sealing valve core 12 is pressed down, the wine gap 17 becomes larger, the spring 19 is compressed, the top extension edge of the sliding hole is no longer in close contact with the top of the infusion pipe 14, and the wine can flow out from the wine gap 17 or be poured in.

[0035] Further, the bottom of the mounting seat 5 is provided with the dip tube 18, the dip tube 18 has a middle-through structure, the dip tube 18 is connected with the wine pipeline in penetration, the sealing valve core 12 is slidably arranged on the infusion pipe 14 through the sliding hole, the diameter of the infusion pipe 14 is smaller than the hole diameter of the sliding hole, and the wine in the inner bag 2 flows into the wine pipeline in the mounting seat 5 through the dip tube 18, and the wine needs to pass through the wine pipeline when being poured into the inner bag 2.

[0036] Further, the position of the spring 19 is described, the bottom of the sealing valve core 12 is sleeved with the spring 19, one end of the spring 19 is in contact with the bottom of the sealing valve core 12, and the other end of the spring 19 is in contact with the mounting seat 5; as shown in the drawings, the sealing valve core 12 and the mounting seat 5 are both provided with a limiting portion extending to the direction of the spring 19, the limiting portion has a cylindrical structure, and the limiting portion is used for limiting the position of the spring 19 in the buffer cavity 6. The spring 19 is kept stretching and contracting in the vertical direction.

[0037] In summary, the pressure relief process is that when the pressure inside the inner bag 2 is too large, the gas emitted by the inner bag 2 pushes the sealing spool of the first pressure relief valve 3 to enter the air passage 7 and then enters the buffer cavity 6. When the pressure in the buffer cavity 6 reaches the preset valve value of the second pressure relief valve 10, the gas pushes the sealing spool of the second pressure relief valve 10 to enter the pressure relief cavity 9 and is discharged to the outside environment through the pressure relief hole 11.

[0038] The wine taking process is that the sealing spool 12 is pressed downward by the dispenser to open the wine gap and the gas charging gap. Since the first pressure relief valve 3 and the second pressure relief valve 10 used are both one-way valves, the gas charged will not enter the wine pipeline. The gas sequentially passes through the gas charging gap, the buffer cavity 6, the air passage 7, the exhaust hole 8, and finally enters between the barrel body 1 and the inner bag 2, so that the pressure between the barrel body 1 and the inner bag 2 increases, and the wine in the inner bag 2 is squeezed out. The wine sequentially passes through the tapping pipe 18, the mounting seat 5, the infusion connector 14, the flow hole 15, and finally flows out to the dispenser through the wine gap 17.

[0039] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure. Those skilled in the art can make several modifications and improvements without departing from the concept of the present disclosure, which are all within the protection scope of the present disclosure. Therefore, the protection scope of the present patent should be subject to the appended claims.
