Description

Technical Field

[0001] The utility model belongs to the technical field of wine and beverage containers, in particular to a wine barrel. Background Art

[0002] Liquor such as beer is generally stored and transported in barrels. To facilitate the use of barrels, some barrels are equipped with gas cylinders in the barrel to maintain a constant pressure in the barrel. Specifically, a gas valve is generally provided in the gas cylinder, and a piston is provided on the gas valve. The upper side of the piston is a closed space. The piston moves up and down according to the pressure difference between the upper and lower sides thereof. When moving downward, the piston pushes the gas valve downward to open the gas valve, and the gas cylinder releases carbon dioxide. When the barrel is stored and transported in an empty barrel state, the barrel may be opened by mistake. In the above scheme, there is internal pressure on the upper part of the piston due to the sealing. When the barrel is opened by mistake, the gas in the barrel will be released outside the barrel, thereby causing the air pressure in the barrel to decrease, causing the piston to move downward to open the gas valve, and the gas cylinder releases carbon dioxide gas, resulting in gas waste. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems in the prior art and propose a wine barrel. The technical problem to be solved by the utility model is: how to prevent the wine barrel from being opened by mistake and causing the gas in the gas cylinder to be wasted.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a wine barrel, including a barrel body, a gas cylinder capable of supplying gas to the interior of the barrel body is provided in the barrel body, a gas valve is provided on the gas cylinder, a piston is slidably provided in the gas cylinder, the upper side of the piston has a closed pressure chamber, the lower side of the piston is communicated with the inner cavity of the barrel body, and it is characterized in that a trigger assembly is provided between the gas valve and the piston, and the trigger assembly has two working modes, namely, avoidance mode and activation mode. When the trigger assembly is in the avoidance mode, the piston can move downward relative to the trigger assembly, and when the piston moves upward to a set position, the trigger assembly is transformed into an activation mode and enables the piston to push the trigger assembly downward to move and open the gas valve.

[0005] When the gas cylinder is in the initial state, the trigger assembly is in an avoidance state. After the wine barrel is opened by mistake, the air pressure in the barrel body decreases due to the release of gas to the outside of the barrel. At this time, a pressure difference is generated between the upper and lower sides of the piston, and the pressure on the upper side is greater than the pressure on the lower side. The piston moves downward, but because the piston is slidably connected to the trigger assembly and the piston can move downward relative to the trigger assembly, the trigger assembly is in a relatively static state when the piston moves downward, so that the gas valve will not be opened as the piston moves downward. When in use, high-pressure gas must be filled into the barrel body to move the piston upward. When the filled high-pressure gas causes the piston to move upward to be separated from the trigger assembly, the trigger assembly changes from the avoidance state to the activation state, and the piston can push the trigger assembly downward to open and close the gas valve. Through the cooperation of the trigger assembly and the piston, the piston is slidably connected to the trigger assembly and can move downward relative to the trigger assembly, so that in the mistaken opening state, the pressure difference cannot reach the extent that the piston pushes the trigger assembly. Therefore, the gas valve in contact with the trigger assembly will not move downward with the piston, and the gas cylinder cannot be opened, thereby avoiding the waste of gas in the gas cylinder caused by mistakenly opening the wine barrel.

[0006] In the above-mentioned wine barrel, the trigger assembly has an elastic part, and the piston has a delay groove for accommodating the elastic part in a state of elastic reset force, the notch of the delay groove is downward, when the trigger assembly is in an avoidance state, the elastic part is located in the delay groove, and there is a movable space between the top of the elastic part and the bottom of the delay groove that can move the piston downward, when the piston moves up to the elastic part leaving the delay groove, the elastic part performs elastic recovery so that the trigger assembly is switched to an activated state, at which time the piston can press down the elastic part to open the air valve. Through the positional relationship between the delay groove on the piston and the elastic part of the trigger assembly, there is an movable space between the top of the elastic part and the bottom of the delay groove that can move the piston downward, so that the trigger assembly is in a relatively static state while the piston moves downward, avoiding the trigger assembly from moving downward with the piston. The trigger assembly can automatically change from the avoidance state to the activation state when the elastic part recovers, thereby improving convenience and practicality.

[0007] In the above-mentioned wine barrel, the trigger assembly further comprises a main body, the main body is in contact with and connected to the air valve, and the main body comprises an exhaust hole communicating with the air valve.

[0008] In the above wine barrel, the elastic part is an elastic sheet extending upward from the main body, the number of the elastic sheets is at least two and they are symmetrically distributed along the circumference of the exhaust hole, and when the elastic sheet is located in the delay groove, the elastic sheet abuts against the inner side wall of the delay groove. When the elastic sheet abuts against the inner side wall of the delay groove, it has a tendency to open outwards, and when the wine barrel is opened by mistake and the piston moves downward, there is friction between the piston and the elastic sheet, but the friction cannot meet the thrust required to open the gas valve, nor can it overcome the upward thrust of the gas valve on the trigger assembly, so the friction can be ignored.

[0009] In the above wine barrel, the piston is provided with an annular groove with a notch downward along the circumference of the delay groove, and after the elastic sheet leaves the delay groove, the elastic sheet is located in the annular groove and the top of the elastic sheet abuts against the bottom of the annular groove. During the process of inflating the barrel body, as the piston moves upward, the elastic sheet leaves the inner side wall of the delay groove and elastically recovers to be located in the annular groove, and when the piston moves downward, it pushes the elastic sheet downward to open the air valve.

[0010] In the above-mentioned wine barrel, the elastic part is an abutment pin, there are two abutment pins, the side of the main body is symmetrically provided with spring grooves, the two abutment pins are correspondingly arranged in the two spring grooves, a reset spring is arranged between the spring groove and the abutment pin, and when the abutment pin is located in the delay groove, the abutment pin abuts against the inner side wall of the delay groove, and the reset spring is compressed. When the abutment pin abuts against the inner side wall of the delay groove, it has a tendency to move outward under the action of the reset spring, and when the wine barrel is opened by mistake and the piston moves downward, there is friction between the piston and the abutment pin, but this friction cannot meet the thrust required for the opening of the gas valve, nor can it overcome the upward thrust of the gas valve on the trigger assembly, so this friction can be ignored.

[0011] In the above-mentioned wine barrel, an abutment groove is provided at the notch of the delay groove, and after the abutment pin leaves the delay groove, it abuts against the side wall of the abutment groove under the elastic restoring force of the restoring spring. In the activated state, the abutment pin moves outward under the elastic restoring force of the spring and abuts against the side wall of the abutment groove. When the piston moves downward, it pushes the abutment pin downward. Since the abutment pin part is still located in the spring groove, the accuracy of the downward movement of the main body is improved, thereby improving the control accuracy of the opening and closing of the gas valve.

[0012] In the above-mentioned wine barrel, a wine guide pipe is provided beside the gas cylinder, and a wine outlet pipe is connected to the barrel body, and the wine guide pipe and the wine outlet pipe are in communication. When the carbon dioxide in the gas cylinder is released, the air pressure in the barrel body rises, so that the air pressure acts on the liquid surface, so that the beer in the barrel body flows out after passing through the wine guide pipe and the wine outlet pipe in sequence.

[0013] Compared with the prior art, the utility model has the following advantages: through the cooperation between the trigger assembly and the piston, the piston is provided with a movable space that enables the piston to move downward relative to the trigger assembly, so that in the mistaken opening state, the pressure difference cannot reach the extent that the piston pushes the trigger assembly. Therefore, the gas valve in contact with the trigger assembly will not move downward with the piston, and the gas cylinder cannot be opened, thereby avoiding the waste of gas in the gas cylinder caused by mistaken opening of the wine barrel.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to the following embodiments.

[0023] Embodiment 1

[0024] Combination Figure 1-4As shown, a wine barrel comprises a barrel body 1, wherein a gas cylinder 2 capable of supplying gas to the inside of the barrel body 1 is arranged inside the barrel body 1, a gas valve 3 is arranged on the gas cylinder 2, a piston 4 is slidably arranged inside the gas cylinder 2, the upper side of the piston 4 has a closed pressure chamber 41, and the lower side of the piston 4 is communicated with the inner cavity of the barrel body 1, and is characterized in that a trigger assembly 5 is arranged between the gas valve 3 and the piston 4, and the trigger assembly 5 has two working modes of avoidance and activation. When the trigger assembly 5 is in the avoidance mode, the piston 4 can move downward relative to the trigger assembly 5, and when the piston 4 moves upward to the set position, the trigger assembly 5 can be transformed into the activation mode and the piston 4 can push the trigger assembly 5 downward to move and open the gas valve 3.

[0025] The trigger assembly 5 has an elastic part 51 and a main body 52. ​​The piston 4 has a delay groove 42 for accommodating the elastic part 51 in the state of elastic reset force. The notch of the delay groove 42 faces downward. When the trigger assembly 5 is in the avoidance state, the elastic part 51 is located in the delay groove 42, and there is an activity space 421 between the top of the elastic part 51 and the bottom of the delay groove 42 to enable the piston 4 to move downward. When the piston 4 moves up to the elastic part 51 and leaves the delay groove 42, the elastic part 51 performs elastic recovery so that the trigger assembly 5 is switched to the activated state. At this time, the piston 4 can press the elastic part 51 downward to open the gas valve 3. The main body 52 is in contact with the gas valve 3 and has an exhaust hole 521 communicated with the gas valve 3.

[0026] The elastic part 51 is an elastic sheet 51a extending upward from the main body 52. ​​There are at least two elastic sheets 51a and they are symmetrically distributed along the circumference of the exhaust hole 521. When the elastic sheet 51a is located in the delay groove 42, the elastic sheet 51a abuts against the inner wall of the delay groove 42. An annular groove 43 with a notch downward is provided on the piston 4 along the circumference of the delay groove 42. After the elastic sheet 51a leaves the delay groove 42, it is located in the annular groove 43 and the top of the elastic sheet 51a abuts against the bottom of the annular groove 43. When the elastic sheet 51a abuts against the inner wall of the delay groove 42, it has a tendency to open outward. When the wine barrel is opened by mistake and the piston 4 moves downward, there is friction between the piston 4 and the elastic sheet 51a, but the friction cannot meet the thrust required for the opening of the gas valve 3, nor can it overcome the upward thrust of the gas valve 3 on the trigger assembly 5, so the friction can be ignored.

[0027] During the process of inflating the barrel 1 , as the piston 4 moves upward, the elastic sheet 51 a leaves the inner wall of the delay groove 42 and elastically recovers to be located in the annular groove 43 . When the piston 4 moves downward, it pushes the elastic sheet 51 a downward to open the air valve 3 .

[0028] A wine guide pipe 7 is provided beside the gas cylinder 2, and a wine outlet pipe 6 is connected to the wine barrel 1, and the wine guide pipe 7 and the wine outlet pipe 6 are in communication. When the carbon dioxide in the gas cylinder 2 is released, the air pressure in the barrel body 1 rises, so that the air pressure acts on the liquid surface, so that the beer in the barrel body 1 flows out after passing through the wine guide pipe 7 and the wine outlet pipe 6 in sequence.

[0029] When the gas cylinder 2 is in the initial state, the elastic sheet 51a of the trigger assembly 5 is arranged in the delay groove 42 of the piston 4. At this time, the elastic sheet 51a is in contact with the inner groove wall of the delay groove 42 and has an active space 421 between the elastic sheet 51a and the bottom of the delay groove 42 so that the piston 4 can move downward relative to the trigger assembly 5. After the wine barrel is opened by mistake, the air pressure in the barrel body 1 is reduced due to the release of gas to the outside of the barrel. At this time, a pressure difference is generated between the upper and lower sides of the piston 4, and the pressure on the upper side is greater than the pressure on the lower side. The piston 4 moves downward, but since there is an active space 421 between the elastic sheet 51a and the bottom of the delay groove 42, there is friction between the elastic sheet 51a and the inner wall of the delay groove 42 when the piston 4 moves downward, but the friction cannot reach the thrust required for the gas valve 3 to move downward. Therefore, when the piston 4 moves downward, the trigger assembly 5 is in a relatively static state, so that the gas valve 3 will not be opened as the piston 4 moves downward. When in use, high-pressure gas is filled into the barrel body 1, and the piston 4 moves upward until the elastic sheet 51a leaves the delay groove 42. The elastic sheet 51a that has left the delay groove 42 elastically recovers to open outward and is located in the annular groove 43, and its top abuts against the bottom of the annular groove 43. When the pressure on the upper side of the piston 4 is greater than the pressure in the barrel body 1, the piston 4 moves downward. At this time, the elastic sheet 51a of the trigger assembly 5 moves downward with the piston 4, and the air valve 3 that is in contact with the main body 52 also moves downward to open the gas cylinder 2, releasing gas into the barrel body 1. The air pressure in the barrel body 1 increases accordingly, and the air pressure directly acts on the liquid surface, and the beer flows out after passing through the wine guide pipe 7 and the wine outlet pipe 6 once.

[0030] The utility model cooperates with the trigger component 5 and the piston 4, and the piston 4 is provided with an activity space 421 that enables the piston 4 to move downward relative to the trigger component 5, so that in the mistaken opening state, the pressure difference cannot reach the extent that the piston 4 pushes the trigger component 5, so the gas valve 3 contacting and connected with the trigger component 5 will not move downward with the piston 4, avoiding the waste of gas in the gas cylinder caused by mistaken opening of the wine barrel.

[0031] Embodiment 2

[0032] Combination Figure 5 , 6The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the elastic portion 51 is an abutment pin 51b, and there are two abutment pins 51b. A spring groove 522 is symmetrically provided on the side of the main body 52. ​​The two abutment pins 51b are correspondingly arranged in the two spring grooves 43. A return spring 51c is provided between the spring groove 522 and the abutment pin 51b. When the abutment pin 51b is located in the delay groove 42, the abutment pin 51b abuts against the inner side wall of the delay groove 42, and the return spring 51c is compressed. An abutment groove 44 is provided at the notch of the delay groove 42. After the abutment pin 51b leaves the delay groove 42, it abuts against the side wall of the abutment groove 44 under the elastic return force of the return spring 51c. The abutment pin 51b is located in the abutment groove 44. When the piston 4 moves downward, the abutment pin 51b is pushed downward, and the main body 52 moves accordingly to open the air valve 3.

[0033] Embodiment 3

[0034] Combination Figure 7 The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: a wine bag 8 is provided in the barrel body 1, the wine bag 8 is made of a flexible material, and the wine bag 8 is sleeved outside the gas cylinder 2. The inner cavity of the wine bag 8 may be in communication with the lower side of the piston 4, or may not be in communication with the lower side of the piston 4. When the inner cavity of the wine bag 8 is in communication with the lower side of the piston 4, the carbon dioxide released by the gas cylinder 2 is directly released into the wine bag 8, and the air pressure in the wine bag 8 directly acts on the liquid surface, thereby pumping out the beer; when the inner cavity of the wine bag 8 is not in communication with the lower side of the piston 4, the gas in the gas cylinder 2 is released into the space outside the wine bag 8 in the barrel body 1, thereby compressing the wine bag 8, so that the beer in the wine bag 8 flows out through the wine guide pipe 7 and the wine outlet pipe 6 in sequence.
