Description

Technical Field

[0001] This disclosure generally relates to the field of beverage drinking equipment technology, and specifically to a plate-type wine spear and wine barrel. Background Technology

[0002] In the field of wine storage and consumption, wine barrels are common wine storage containers. Wine spears are needed to facilitate the extraction of wine and achieve gas balance in order to ensure the convenience of wine retrieval and the quality of the wine. As a key supporting component of wine barrels, the rationality of its structure and its performance directly affect the overall use of the wine barrels. They are widely used in commercial and home wine storage scenarios.

[0003] In the existing technology, some wine spears require many complex components to achieve the functions of guiding wine and air, resulting in redundant structures and cumbersome assembly processes, which increases the difficulty and cost of assembly. At the same time, the wine guiding structure of some wine spears cannot extend fully into the wine barrel, which can easily lead to a lot of wine residue at the bottom of the barrel, resulting in waste. In addition, the channel control design of some wine spears is difficult to balance the stability of wine extraction and the sealing performance when not extracting wine, which affects the performance.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1 Please refer to Figures 1-9 This embodiment provides a plate-type wine spear, including a wine spear body 100 and a wine guiding mechanism 200: wherein, the wine spear body 100 includes: Mounting component 110 is hollow inside and has an external interface 111 at one end and a connecting component at the other end. A wine guiding passage 141 is formed inside the connecting component. The wine guiding passage 141 extends into the wine barrel through the wine guiding mechanism 200. An air guiding passage 142 is formed between the connecting component and the inner wall of the mounting component 110. A fixing cap 120 is detachably connected to the opening of the barrel, and after connection, the mounting part 110 is fixed to the opening of the barrel; A switch assembly is provided at the external interface 111 and includes a first state and a second state. In the first state, the external interface 111 is connected to the wine guiding passage 141 and the air guiding passage 142 respectively. In the second state, the external interface 111 is disconnected from the wine guiding passage 141 and the air guiding passage 142.

[0021] Specifically, the mounting component 110 has a hollow tubular structure. One end has an integrally formed external interface 111 for detachable connection with external dispensing equipment (such as a dispenser or dispensing tap), ensuring a tight and universal connection. The other end has a detachable connecting component, providing a basic carrier for the formation of the wine guiding passage 141 and the air guiding passage 142. The fixing cap 120 adopts a ring-shaped structure design, with threads on the inner wall that fit the outer wall of the barrel opening, allowing for a stable and detachable connection with the barrel opening. When the fixing cap 120 is locked to the barrel opening, it can limit and fix the middle part of the mounting component 110 at the barrel opening, preventing the wine spear from shifting or falling off during use, while also enhancing the sealing performance at the barrel opening. When the mounting component 110 is installed at the barrel opening, the gap between the two is sealed by the second sealing ring 180. Figure 6 As shown.

[0022] The wine guiding passage 141 is formed inside the connecting component. One end of it communicates with the inside of the barrel through the wine guiding mechanism 200, and the other end extends into the mounting component 110 and corresponds to the position of the external interface 111, forming a complete wine outflow channel to ensure that the wine can be smoothly outflowed from the inside of the barrel to the external wine dispensing device. The air guiding passage 142 is formed by the gap between the outer wall of the connecting component and the inner wall of the mounting component 110. One end of it communicates with the inside of the barrel through the venting structure on the connecting component, and the other end also corresponds to the position of the external interface 111. When the wine is outflowed, external gas can enter the inside of the barrel through this passage to balance the air pressure inside and outside the barrel, preventing the wine from being unable to flow smoothly due to excessively low air pressure inside the barrel.

[0023] The switch assembly is installed inside the mounting part 110 corresponding to the external interface 111. It has two working states, which synchronously control the connection or disconnection of the external interface 111 with the wine guide passage 141 and the air guide passage 142 through state switching. When the external wine dispensing device is connected to the external interface 111 and a preset pressure is applied, the switch assembly switches to the first state. At this time, the external interface 111 is simultaneously connected to the wine guide passage 141 and the air guide passage 142. Under the action of the air pressure difference, the wine in the barrel enters the wine guide passage 141 through the wine guide mechanism 200, and then flows into the external wine dispensing device through the external interface 111. At the same time, external gas enters the air guide passage 142 through the external interface 111, and then enters the inside of the barrel through the connecting component, realizing air pressure balance and ensuring the continuous and stable output of wine. When the external wine dispensing device is disconnected, or when no preset pressure is applied, the switch assembly automatically resets to the second state. At this time, the sealing structure of the switch assembly simultaneously seals the connection between the wine guide passage 141 and the external interface 111, and the connection between the air guide passage 142 and the external interface 111, which not only prevents the wine in the barrel from leaking, but also prevents external air from entering the barrel and causing the wine to oxidize and deteriorate, thus ensuring the quality of the wine.

[0024] One end of the wine guiding mechanism 200 is fixedly connected to the connecting component, and the other end extends into the barrel. Its length is designed according to the depth of common barrels to ensure full contact with the wine inside. As an extension of the wine guiding passage 141, its core function is to guide the wine in the barrel to the wine guiding passage 141 of the connecting component, and then export it through the external interface 111, without affecting the gas flow in the gas guiding passage 142. Preferably, the plate-type wine spear provided in this embodiment is suitable for 20-liter barrels.

[0025] Furthermore, the connectivity component includes: The support 130 includes a connecting part 131 and a blocking part 132. The connecting part 131 is detachably connected to the mounting part 110. The blocking part 132 has a mounting part 133 through its center. The blocking part 132 has a vent 134 on its periphery around the mounting part 133. A connecting pipe 140 is connected to the mounting part 133 and forms the wine guiding passage 141 inside; one end of the connecting pipe 140 extends into the mounting part 110 and is provided with a wine inlet 143, and the other end is connected to the wine guiding mechanism 200; the connecting pipe 140 and the inner wall of the mounting part 110 form the air guiding passage 142.

[0026] Specifically, the connecting part 131 is tubular, with threads on its outer wall that fit the inner wall of the mounting part 110. It can be detachably connected to the end of the mounting part 110 away from the outer interface 111, sealing the gap after assembly to prevent gas and liquid leakage; its length is adapted to the depth of the mounting part 110. The sealing part 132 is disc-shaped, with a diameter larger than the outer diameter of the connecting part 131 and adapted to the outer diameter of the mounting part 110. The sealing part 132 separates the interior of the mounting part 110 from the interior space of the barrel. The mounting part 133 is a tubular structure that runs through the central axis of the sealing part 132. Its inner wall has an interference fit structure adapted to the connecting pipe 140 for fixing the connecting pipe 140; its two ends extend towards the mounting part 110 side and the barrel side respectively, ensuring that the connecting pipe 140 can simultaneously extend into the spaces on both sides to achieve passage connection. Three or more evenly distributed strip-shaped or circular holes are provided around the mounting part 133 to connect the inside of the barrel with the air passage 142, so that external gas can enter the barrel to balance the air pressure.

[0027] The wine guiding passage 141 is a hollow channel along the axis inside the connecting pipe 140, with its two ends corresponding to the interior of the mounting component 110 and the interior of the wine barrel, respectively, enabling the flow of wine from the wine barrel to the mounting component 110. The air guiding passage 142 is formed by the annular gap between the outer wall of the connecting pipe 140 and the inner wall of the mounting component 110, with one end connected to the outer interface 111 of the mounting component 110 and the other end connected to the interior of the wine barrel through the vent 134 of the support 130. The connecting pipe 140 has 2-4 side holes at one end extending into the mounting component 110, which are evenly distributed around the circumference of the connecting pipe 140; these holes connect the wine guiding passage 141 to the interior of the mounting component 110, allowing wine to flow into the mounting component 110 and then exit from the outer interface 111. The holes are positioned to correspond to the sealing component 150 of the switch assembly for easy sealing.

[0028] Furthermore, the switching assembly includes: A sealing element 150 is sleeved on the connecting pipe 140 and has a gap between it and the inner wall of the mounting element 110; a sealing gasket 151 is provided on the side of the sealing element 150 near the external interface 111. The elastic element 160 has one end abutting against the sealing element 150 and the other end abutting against the sealing part 132; when the elastic element 160 is in its natural state, it squeezes the sealing element 150 to block the external interface 111, and the sealing element 150 blocks the wine inlet 143.

[0029] Specifically, the sealing component 150 has a through hole at its center that fits the outer wall of the connecting pipe 140. It is fitted onto the portion of the connecting pipe 140 that extends into the mounting component 110, with a pre-reserved gap between it and the inner wall of the mounting component 110. This gap is part of the gas guide passage 142, ensuring normal gas flow. A sealing gasket 151 is fixed to the side of the sealing component 150 near the external interface 111 by adhesive bonding or embedding. The sealing gasket 151 is made of an elastic sealing material, and its diameter is larger than the diameter of the external interface 111. When the sealing component 150 moves outward, the sealing gasket 151 can tightly fit against the port of the external interface 111, achieving a seal on the external interface 111. The inner wall of the sealing member 150 is set to correspond to the wine inlet 143 of the connecting pipe 140. When the sealing member 150 is in the initial position, its inner wall can cover the wine inlet 143, blocking the connection between the wine guiding passage 141 and the interior of the mounting member 110. When the sealing member 150 moves inward, the inner wall separates from the wine inlet 143, the wine inlet 143 opens, and the wine guiding passage 141 is opened.

[0030] The elastic element 160 is sleeved on the connecting pipe 140, with one end abutting against the side of the sealing element 150 away from the external interface 111, and the other end abutting against the sealing part 132 of the support 130, in a compressed and pre-tightened state. When the elastic element 160 is in its natural state, its elastic restoring force pushes the sealing element 150 to move closer to the external interface 111, causing the sealing gasket 151 to seal the external interface 111, while the inner wall of the sealing element 150 seals the wine inlet 143. At this time, the switch assembly is in the second state. When the external wine dispensing device is connected to the external interface 111 and applies inward pressure, the pressure overcomes the elastic force of the elastic element 160, pushing the sealing element 150 to move closer to the sealing part 132, separating the sealing gasket 151 from the external interface 111, opening the wine inlet 143, and switching the switch assembly to the first state.

[0031] Furthermore, the wine guiding mechanism 200 includes: Connector 210, which is detachably connected to the connecting pipe 140, and a connecting plate 211 extending radially is provided on the outer side wall of connector 210; The extension 220 includes a connecting section 221 and an extension section 222. The connecting section 221 is connected to the end of the connector 210 away from the connecting pipe 140. The extension section 222 is used to extend to the bottom of the barrel. A wine guide port 230 communicating with the inside of the connector 210 is provided between the extension section 222 and the connecting section 221.

[0032] Specifically, the inner wall of one end of the connector 210 is provided with a thread that matches the outer wall of the end of the connecting pipe 140 away from the outer interface 111, allowing for a detachable connection with the connecting pipe 140. After assembly, it is sealed by the third sealing ring 190 to prevent leakage of liquor from the joint gap. The outer wall of the connector 210 is integrally formed or welded with a connecting plate 211 along the radial direction. The connecting plate 211 is disc-shaped or rectangular, and its diameter is slightly smaller than the limiting dimension inside the barrel opening. When the liquor guiding mechanism 200 is assembled with the connecting pipe 140, the connecting plate 211 extends into the barrel. The connecting section 221 is the upper part of the extension 220, and its inner wall matches the outer wall of the end of the connector 210 away from the connecting pipe 140. It is fixed to the connector 210 by interference fit or snap connection. The extension section 222 is the main part of the extension 220. Its length is designed according to the common barrel depth to ensure that its lower end can be close to the bottom of the barrel, reducing liquor residue at the bottom of the barrel. A wine guide port 230 is provided at the junction of the extension section 222 and the connecting section 221. The wine guide port 230 is connected to the internal channel of the connector 210. The wine in the barrel can enter the interior of the extension section 220 through the wine guide port 230, and then flow into the wine guide passage 141 of the connecting pipe 140 through the connector 210, so as to realize the wine export.

[0033] In this embodiment, the plate-type wine spear is suitable for double-layer barrels, which include an outer barrel wall and a wine bag located inside the outer barrel wall, containing wine. During installation, the wine guide mechanism 200 is inserted into the wine bag, and the opening of the wine bag is sealed to the connecting plate 211. The gap between the wine bag and the outer barrel wall is connected to the air guide passage 142. During the dispensing process, as the wine is continuously discharged, the wine bag will continuously shrink and deform due to external air pressure. The core function of the extension section 222 is to support the wine bag through its own structure, preventing the wine bag from clumping together after shrinkage and obstructing the flow of wine.

[0034] Furthermore, at least one groove 223 is provided on each of the opposite sides of the extension section 222, and the groove 223 extends along the length direction of the extension section 222 to the wine guide port 230.

[0035] Specifically, the groove 223 is a key supporting design of the extension section 222. It is opened through the extension section 222 and extends to the wine guide port 230. At least one groove 223 is provided on each side of the extension section 222. Its actual function is to reserve a passage for the wine. Even if the wine bag completely shrinks and tightly wraps the extension section 222 in the later stage of wine dispensing, the remaining wine in the wine bag can still be smoothly gathered to the wine guide port 230 through the channel formed by the groove 223, and then discharged through the wine guide passage 141, thereby ensuring that the wine in the wine bag is fully discharged and reducing residue.

[0036] Furthermore, the outer wall of the end of the connector 210 away from the connecting pipe 140 is provided with an outer protrusion 212, and the inner wall of the extension section 222 is provided with an inner protrusion 224 for engaging with the outer protrusion 212, and the inner protrusion 224 is provided with an inclined guide surface.

[0037] Specifically, by setting an outer protrusion 212 and an inner protrusion 224, the inclined guide surface on the inner protrusion 224 can guide the outer protrusion 212 to smoothly engage during assembly, thereby achieving a quick and detachable connection between the connector 210 and the extension 220.

[0038] Furthermore, at least two first sealing rings 170 are embedded on the outer wall of the connecting pipe 140 on the side of the wine inlet 143 away from the external interface 111.

[0039] Specifically, the sealing effect of the first sealing ring 170 prevents the wine in the wine guiding passage 141 from leaking into the gap between the connecting pipe 140 and the inner wall of the mounting part 110, ensuring that the wine is only discharged through the wine inlet 143, while avoiding the mixing of the wine with the gas in the gas guiding passage 142, thus ensuring the stable and independent operation of the wine guiding and gas guiding functions.

[0040] Furthermore, the inner wall of the connecting part 131 is provided with a plurality of first support plates 135, and the outer wall of the mounting part 133 is provided with a plurality of second support plates 136. The first support plates 135 and the second support plates 136 are provided with guide slopes on the side that are close to each other.

[0041] Specifically, the first support plate 135 enhances the structural strength of the connecting part 131, preventing deformation of the connecting part 131 when assembled with or under stress with the mounting part 110; the second support plate 136 improves the structural stability of the mounting part 133, preventing displacement or damage of the mounting part 133 when fixing the connecting pipe 140. By providing inclined guide slopes on the sides of the first support plate 135 and the second support plate 136 that are close to each other, the guide slopes can guide the elastic element 160 into the support seat 130 when assembling the elastic element 160 of the switch assembly.

[0042] Example 2 Please refer to Figure 10 Based on Embodiment 1 above, this embodiment provides another plate-type wine spear. The contents that are the same as in Embodiment 1 will not be repeated here; the differences are as follows: The wine guiding mechanism 200 is a wine guiding tube 240, which is inserted into the connecting tube 140, and a wine guiding port 230 is provided at one end away from the connecting tube 140.

[0043] Specifically, the wine spear provided in this embodiment is adapted to a single-layer barrel, meaning the barrel only includes the outer wall and does not include the wine bag inside. In this embodiment, the wine guiding mechanism 200 is a separate wine guiding tube 240. One end of the wine guiding tube 240 is directly inserted into the end of the connecting tube 140 away from the external interface 111. The two are quickly assembled and connected to the wine guiding passage 141 through the insertion and engagement, without the need for a complex connection structure. The end of the wine guiding tube 240 away from the connecting tube 140 is provided with a wine guiding port 230. Because it is adapted to a single-layer barrel, the overall length of the wine guiding tube 240 is designed according to the depth of the single-layer barrel, and can extend to near the bottom of the barrel. The wine can enter the wine guiding tube 240 through the wine guiding port 230 and then be discharged through the wine guiding passage 141 of the connecting tube 140.

[0044] Example 3 Please refer to Figures 11-12 Based on the above embodiments 1 and 2, this embodiment provides a wine barrel, including a barrel body 300 and a plate-type wine spear as described in embodiment 1 or embodiment 2, which is installed at the opening of the barrel body 300.

[0045] Specifically, such as Figure 11 As shown, the barrel is also equipped with a handle 400 at one end of the barrel body 300 opening for easy lifting.

[0046] The structure of the barrel body 300 differs depending on the type of split-plate spear used with the barrel. When the split-plate spear used with the barrel has the structure described in Example 2, the opening of the barrel body 300 only needs to be connected to the spear fixing cap 120, and the guide tube 240 is inserted into the barrel body 300, ensuring that the guide tube 240 extends to near the bottom of the barrel body 300. When the split-plate spear used with the barrel has the structure described in Example 1, a wine bag 500 is also provided inside the barrel body 300; during assembly, the opening of the barrel body 300 is connected to the spear fixing cap 120, and the extension section 222 is inserted into the wine bag 500. The opening of the wine bag 500 is sealed to the connecting plate 211, such as... Figure 12 As shown.

[0047] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
