Description

Technical Field

[0001] The utility model belongs to the technical field of container plugs, and particularly relates to a pressing and air-releasing manual vacuum wine stopper. Background Art

[0002] With the improvement of people's living standards, red wine has become increasingly popular. At present, most of the wine bottle stoppers on the market are wooden soft stoppers. After opening, the stoppers are often damaged, and moreover, after re-capping the stoppers, it is impossible to prevent the red wine in the bottle from contacting the air. Usually, people cannot finish a whole bottle of red wine at once after opening a bottle of red wine. And the red wine will be oxidized after contacting the air, resulting in a deteriorated taste. Therefore, it is very important to preserve the remaining red wine and avoid its oxidation.

[0003] In order to avoid the oxidation problem of opened red wine, there is now a vacuum wine stopper on the market. This wine stopper is mainly composed of a stopper seat and an air extraction structure. The air extraction structure mainly has two types: manual piston air extraction and electric air pump air extraction. When in use, the stopper seat is covered on the wine bottle mouth to block the bottle mouth, and then the air in the bottle is extracted by the air extraction structure, so that the inside of the bottle is kept in a vacuum state, so that the remaining red wine in the bottle is stored in a vacuum state to avoid the oxidation of the red wine.

[0004] However, the existing vacuum wine stoppers only have the functions of vacuum extraction and sealing. After the air in the bottle is extracted, due to the large air pressure difference between the inside and outside of the bottle, it is difficult to take out the wine stopper from the bottle mouth, which is inconvenient to use. And forcibly pulling out the wine stopper is also easy to cause damage to the wine stopper or spillage of the red wine. Content of the Utility Model

[0005] Aiming at the above deficiencies in the prior art, the purpose of the utility model is to provide a pressing and air-releasing manual vacuum wine stopper that can be easily opened.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows: A pressing and air-releasing manual vacuum wine stopper, including a first stopper seat, a hollow air extraction pipe connected to the middle of the first stopper seat, a piston rod slidably arranged in the air extraction pipe, a handle arranged at the upper end of the piston rod, the handle is located above the first stopper seat, the piston rod passes through the middle of the first stopper seat, an air release rod is slidably arranged in the above-mentioned piston rod, the upper end part of the air release rod extends out of the piston rod, the lower end of the air release rod can extend out of and retract from the lower end of the piston rod, an air hole is arranged at the bottom of the air extraction pipe, a deformable hole plug is arranged at the position of the air hole, the hole plug blocks the air hole in the natural state, and when the lower end of the air release rod slides out of the lower end of the piston rod and squeezes the hole plug to deform, the air hole will be opened.

[0007] In the above scheme, when the red wine is opened but not finished, the user can use the wine stopper to seal the bottle mouth. Specifically, the user can insert the suction tube into the bottle mouth, and at the same time block the bottle mouth through the first stopper seat, and then operate the handle to drive the piston rod to slide up and down to extract the air in the bottle, so that the bottle reaches a vacuum state, so that the remaining red wine in the bottle is preserved in a vacuum state to prevent the red wine from being oxidized. When the user needs to enjoy the remaining red wine next time, he can press the deflation rod downward, so that the lower end of the deflation rod slides out of the lower end of the piston rod, and squeezes the hole plug to deform and open the air hole. At this time, since the bottle is in a negative pressure state, the air outside the bottle will automatically be discharged into the bottle from the air hole, so that the air pressure inside and outside the bottle is balanced, so that the wine stopper can be easily pulled out of the bottle mouth, and the wine stopper opening operation is convenient and labor-saving.

[0008] Furthermore, a convex ring is provided at the edge of the upper end surface of the above-mentioned air hole, and a notch connected to the air hole is opened on the side wall of the convex ring. The hole plug includes a plug column, a plug cap connected to the upper end of the plug column, and a second plug seat connected to the lower end of the plug column. The plug column is inserted into the air hole, and the second plug seat is located at the lower side of the air hole. The second plug seat can prevent the plug column from slipping out of the air hole upward, thereby ensuring the installation stability of the hole plug; the above-mentioned plug cap is located at the upper side of the air hole, and an air flow channel connected to the notch of the convex ring is formed between the plug column and the second plug seat and the air hole. In a natural state, the plug cap is sleeved on the outer side of the convex ring and connected to the upper end of the air hole. The surfaces of the plugs are pressed against each other to block the gap, and at this time, air cannot flow into the pore from the gap, thereby realizing the structural function of the hole plug to block the pore in a natural state; and when the lower end of the air-release rod is pressed to slide out of the lower end of the piston rod and squeeze the plug cap, the middle part of the upper side of the plug cap is subjected to the downward force of the air-release rod, while the lower side of the plug cap is simultaneously subjected to the upward force of the convex ring, so that the plug cap is deformed upward and outward and separated from the upper end surface of the pore, thereby opening the gap, and the gap is connected to the pore, so opening the gap will open the pore, thereby realizing the structural function of squeezing the hole plug to deform and open the pore.

[0009] Furthermore, the outer wall of the deflation rod is provided with a first sealing ring groove, the first sealing ring groove is sleeved with a first sealing ring, the outer side of the first sealing ring abuts against the inner wall of the piston rod, and the first sealing ring can improve the sealing between the deflation rod and the inner side of the piston rod.

[0010] Furthermore, a bottom cover is provided at the bottom of the above-mentioned air extraction pipe, and the air hole is opened at the bottom of the bottom cover. The side wall of the bottom cover is sleeved on the inner side of the lower end of the air extraction pipe, and the side wall of the bottom cover is tightly matched or clamped with the inner side of the lower end of the air extraction pipe. When the bottom cover needs to be removed, it is necessary to forcefully pull the bottom cover out of the lower end of the air extraction pipe, and after the bottom cover is removed and separated, the disassembly and assembly operation of the hole plug and the bottom cover can also be facilitated; in addition, the side wall of the bottom cover is tightly matched or clamped with the inner side of the lower end of the air extraction pipe, so that the bottom cover will not fall off during the air extraction and deflation operation.

[0011] Further, a receiving groove is provided on the bottom cover described above, and the second socket is located in the receiving groove, so that the second socket will not protrude outside the bottom wall of the bottom cover, and the structure is more compact.

[0012] Further, a second sealing ring groove is provided on the outer side wall of the bottom cover described above. A second sealing ring is sleeved in the second sealing ring groove, and the outer side of the second sealing ring abuts against the inner side wall of the air extraction pipe. The second sealing ring can improve the sealing performance between the side wall of the bottom cover and the inner side of the air extraction pipe.

[0013] Further, a return spring is sleeved on the outer side of the air release rod described above. A positioning block is provided on the outer side of the air release rod. The upper end of the return spring abuts against the positioning block, and the lower end abuts against the inner side wall of the piston rod. Without external force, the return spring will push the lower end of the air release rod to slide upward and retract into the piston rod by its own elastic force, without manual operation to slide the air release rod upward for reset, which is convenient for operation and can also prevent the lower end of the air release rod from being accidentally pushed to the plug cap to open the notch; in addition, the return spring can also prevent the air release rod from sliding downward due to the negative pressure generated during the air extraction process, causing the air release rod to abut against the plug cap and affecting the air extraction effect.

[0014] Further, a third sealing ring groove is provided on the outer side wall of the piston rod described above. A third sealing ring is sleeved in the third sealing ring groove. The width of the third sealing ring groove is greater than the thickness of the third sealing ring. An air passage opening is also provided on the upper side wall of the third sealing ring groove, and an air passage groove is provided at the bottom of the third sealing ring groove. The air passage opening is communicated with the air passage groove. During use, when the piston rod is pulled upward, the third sealing ring is pressed against the lower side wall of the third sealing ring groove by the downward frictional force of the inner side wall of the air extraction pipe. At this time, the upper end of the air passage groove is exposed above the third sealing ring. Since the third sealing ring abuts against the lower side wall of the third sealing ring groove and the inner side wall of the air extraction pipe to reach a sealed state, the air passage groove is isolated, so that the outside air of the bottle cannot enter the air extraction pipe through the air passage groove and the third sealing ring, and the air in the bottle will force the plug cap to deform or shift, so that an air flow gap is formed between the plug cap and the upper end face of the air hole to open the notch, so that the air in the bottle is discharged into the space between the third sealing ring and the plug cap on the inner side of the air extraction pipe; when the piston rod is pushed downward, the third sealing ring is pressed against the upper side wall of the third sealing ring groove by the upward frictional force of the inner side wall of the air extraction pipe. At this time, the lower end of the air passage groove is exposed below the third sealing ring, which is equivalent to connecting the upper and lower spaces of the third sealing ring by the air passage groove. At this time, the plug cap is restored to abut against the upper end face of the air hole under the action of air pressure and its own elasticity to seal and block the notch, and the air between the third sealing ring and the plug cap in the air extraction pipe is compressed by the piston rod and discharged out of the bottle through the air passage groove and the air passage opening. In this way, part of the air in the bottle can be pumped out of the bottle, and after repeating the above operation multiple times, all the air in the bottle can be pumped out, so that the inside of the bottle reaches a vacuum state.

[0015] Furthermore, a button groove is provided at the upper position of the above-mentioned handle. The upper end of the air release rod extends out of the upper end of the piston rod and is placed inside the button groove of the handle, which can avoid accidentally pressing the air release rod to slide down and improve the reliability of the wine stopper in use.

[0016] Furthermore, an inner stopper matching the bottle mouth is also provided inside the above-mentioned first stopper seat. The inner stopper is sleeved outside the air extraction pipe, and the bottle mouth can be better sealed through the inner stopper to improve the sealing performance of the wine stopper for the bottle mouth.

[0017] The press-and-release air type hand-pumped vacuum wine stopper of the present utility model can not only evacuate the air in the bottle to reach a vacuum state to avoid the oxidation of red wine, but also when the user needs to enjoy the remaining red wine next time, just press the air release rod to open the notch so that the air outside the bottle can be discharged into the bottle to make the air pressure inside and outside the bottle reach balance, and the wine stopper can be easily pulled out of the bottle mouth, and the operation of opening the wine stopper is very convenient.

[0034] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the drawings:

[0035] Embodiment 1

[0036] As Figure 1-7 shown, this embodiment provides a press-and-release air vent hand-operated vacuum wine stopper, which includes a first plug seat 1, a hollow air extraction pipe 2 connected to the middle of the first plug seat 1, a piston rod 31 slidably disposed in the air extraction pipe 2, and a handle 32 provided at the upper end of the piston rod 31. The handle 32 is located above the first plug seat 1, and the piston rod 31 passes through the middle of the first plug seat 1. An air release rod 51 is slidably disposed in the above-mentioned piston rod 31. The upper end portion of the air release rod 51 extends outside the upper end of the piston rod 31, and the lower end of the air release rod 51 can extend out of and retract from the lower end of the piston rod 31. An air hole 21 is provided at the bottom of the air extraction pipe 2, and a deformable hole plug 41 is provided at the position of the air hole 21. The hole plug 41 is preferably made of rubber. The hole plug 41 blocks the air hole 21 in the natural state, and when the lower end of the sliding air release rod 51 extends outside the lower end of the piston rod 31 and squeezes the hole plug 41 to deform, the air hole 21 will be opened.

[0037] In the above solution, when there is unfinished red wine after opening, the user can use this wine stopper to block the bottle mouth. Specifically, the user can insert the air extraction pipe 2 into the wine bottle from the bottle mouth, and at the same time block the bottle mouth through the first plug seat 1, and then operate the handle 32 to drive the piston rod 31 to slide up and down to extract the air in the bottle, so that the inside of the bottle reaches a vacuum state, so that the remaining red wine in the bottle is stored in a vacuum state to avoid oxidation of the red wine. When the user needs to enjoy the remaining red wine next time, the air release rod 51 can be pressed and slid downwards, so that the lower end of the air release rod 51 slides out of the lower end of the piston rod 31 and squeezes the hole plug 41 to deform and open the air hole 21. At this time, since the inside of the bottle is in a negative pressure state, the air outside the bottle will automatically enter the bottle from the air hole 21, so that the air pressure inside and outside the bottle reaches balance, and thus the wine stopper can be easily pulled out of the bottle mouth, and the operation of opening the wine stopper is convenient and labor-saving.

[0038] Specifically, a bottom cover 22 is provided at the bottom of the above-mentioned air extraction pipe 2. The bottom cover 22 is composed of a bottom cover bottom wall 221 and a bottom cover side wall 222 provided on the upper side edge of the bottom cover bottom wall 221. The above-mentioned air hole 21 is opened in the middle of the bottom cover bottom wall 221. The bottom cover side wall 222 is tightly fitted or clamped with the inner side of the lower end of the air extraction pipe 2. When the bottom cover 22 needs to be disassembled, the bottom cover 22 needs to be pulled out from the lower end of the air extraction pipe 2 with force. After the bottom cover 22 is disassembled and separated, it is also convenient for the disassembly and assembly operation of the hole plug 41 and the bottom cover 22; in addition, the bottom cover side wall 222 is tightly fitted or clamped with the inner side of the lower end of the air extraction pipe 2, so that the bottom cover 22 will not fall off during the air extraction and air release operations.

[0039] As Figure 8 shown, a convex ring 211 is provided on the upper surface of the above-mentioned bottom cover bottom wall 221 corresponding to the edge of the air hole 21, and a notch 212 communicating with the air hole 21 is opened on the side wall of the convex ring 211. As Figure 9 shown, the above-mentioned hole plug 41 includes a plug column 4111, a plug cap 412 connected to the upper end of the plug column 411, and a second plug seat 413 connected to the lower end of the plug column 411.Figure 4 , 5 As shown, the plug post 411 passes through the air hole 21, and the second plug seat 413 is located below the air hole 21. The width of the second plug seat 413 is greater than the diameter of the air hole 21, so as to ensure that the second plug seat 413 cannot pass through the air hole 21, thereby preventing the plug post 41 from protruding upward from the air hole 21 and ensuring the installation stability of the hole plug 41. The above-mentioned plug cap 412 is located above the air hole 21, and an air flow channel communicating with the notch 212 of the convex ring 211 is formed between the plug post 411 and the second plug seat 413 and the air hole 21. Through this air flow channel, the notch 212 can be communicated with the inside of the bottle. In the natural state, the plug cap 412 is sleeved outside the convex ring 211, and the lower edge of the plug cap 412 abuts against the upper surface of the bottom cover bottom wall 221 to block the notch 212. At this time, the entire convex ring 211 is completely covered by the plug cap 412, and at this time, air cannot flow from the notch 212 to the air hole 21, thereby realizing the structural function that the hole plug 41 blocks the air hole 21 in the natural state; as Figure 6 , 7 shown, when the lower end of the air release rod 51 slides out of the lower end of the piston rod 31 and presses the plug cap 412, the middle part of the upper side of the plug cap 412 is subjected to a downward force from the air release rod 51, and the lower side of the plug cap 412 is simultaneously subjected to an upward force from the convex ring 211, so as to cause the upper edge of the plug cap 412 to turn outwards and deform upwards, so that the lower edge of the plug cap 412 is separated from the upper surface of the bottom cover bottom wall 221. At this time, the plug cap 412 is in a state of incompletely covering the convex ring 211, causing an air flow channel to be formed between the lower edge of the plug cap 412 and the upper surface of the bottom cover bottom wall 221 to open the notch 212, and the notch 212 is communicated with the air hole 21, so opening the notch 212 opens the air hole 21, thereby realizing the structural function that squeezing the hole plug 41 to deform will open the air hole 21.

[0040] Embodiment 2

[0041] This embodiment is a further improvement on the basis of the hand-pumped vacuum wine stopper structure of Embodiment 1. The improvement lies in that, as Figure 2 shown, a button groove 320 is provided in the middle of the upper surface of the above-mentioned handle 32, and the upper end of the above-mentioned air release rod 51 extends out of the upper end of the piston rod 31 and is placed in the button groove 320 of the handle 32, so as to avoid accidentally pressing the air release rod 51 to slide downwards and improve the use reliability of the wine stopper.

[0042] As Figure 4 , 5 shown, a first sealing ring groove 511 is provided on the outer side wall of the above-mentioned air release rod 51, and a first sealing ring 52 is sleeved in the first sealing ring groove 511. The outer side of the first sealing ring 511 abuts against the inner side wall of the piston rod 31. The first sealing ring 52 can improve the sealing performance between the air release rod 51 and the inner side of the piston rod 31.

[0043] A return spring 53 is sleeved outside the deflation rod 51 described above. A positioning block 512 is provided on the outside of the deflation rod 51. A support platform 314 is provided on the inner side wall of the piston rod 31 corresponding to the position below the positioning block 512. The upper end of the return spring 53 abuts against the positioning block 512, and the lower end of the return spring 53 abuts against the support platform 314 on the inner side wall of the piston rod 31. Without external force, the return spring 53 will push the lower end of the deflation rod 51 to slide upward and retract into the piston rod 31 by its own elastic force, without the need to manually operate the deflation rod 51 to slide upward for reset, which is convenient to operate and can also prevent the lower end of the deflation rod 51 from being accidentally pushed against the plug cap 412 to open the notch 212. In addition, the return spring 53 can also prevent the deflation rod 51 from sliding downward due to the negative pressure generated during the air extraction process, causing the deflation rod 51 to abut against the plug cap 412 and affecting the air extraction effect.

[0044] As Figure 3 、 4 、shown in FIG. 5, a receiving groove 2210 is provided below the bottom wall 221 of the bottom cover described above. The second plug seat 413 is located in the receiving groove 2210, so that the second plug seat 413 will not protrude outside the bottom wall 221 of the bottom cover, and the structure is more compact. In addition, a second sealing ring groove 2221 is provided on the outer side wall of the side wall 222 of the bottom cover described above. A second sealing ring 223 is sleeved in the second sealing ring groove 2221. The outer side of the second sealing ring 223 abuts against the inner side wall of the air extraction pipe 2. The second sealing ring 223 can improve the sealing performance between the side wall 222 of the bottom cover and the inner side of the air extraction pipe 2.

[0045] Embodiment III

[0046] This embodiment is a further improvement based on the hand-pumped vacuum wine stopper structure of Embodiment II. The improvement lies in that, as Figure 10-12 shown, a third sealing ring groove 311 is provided on the outer side wall of the piston rod 31 described above. A third sealing ring 33 is sleeved in the third sealing ring groove 311. The width of the third sealing ring groove 311 is greater than the thickness of the third sealing ring 33. An air passage port 312 is also provided on the upper side wall of the third sealing ring groove 311. An air passage groove 313 is provided at the bottom of the third sealing ring groove 311. The air passage port 312 is communicated with the air passage groove 313.

[0047] When the hand-pumped vacuum wine stopper of this embodiment is used, when it is necessary to extract the air in the bottle, the air extraction pipe 2 can be first inserted into the wine bottle from the bottle mouth, and at the same time, the bottle mouth is blocked by the first plug seat 1, so as to install the wine stopper on the bottle mouth, as Figure 11 、 12As shown, then pull the handle 32 to drive the piston rod 31 to move upward. The third sealing ring 33 is pressed against the lower side wall of the third sealing ring groove 311 under the action of the downward frictional force of the inner wall of the air extraction pipe 2. At this time, the upper end of the air passage groove 313 is exposed above the third sealing ring 33. Since the third sealing ring 33 is pressed against the lower side wall of the third sealing ring groove 311 and the inner wall of the air extraction pipe 2 to reach a sealed state, the air passage groove 313 is isolated, so that the outside air of the bottle cannot enter the air extraction pipe 2 through the third sealing ring 33 from the air passage groove 313. And the air in the bottle will force the plug cap 412 to deform or slightly shift upward, so that an air flow gap is formed between the plug cap 412 and the upper surface of the bottom cover bottom wall 221 to open the notch 212, so that the air in the bottle is discharged into the space corresponding to the third sealing ring 33 and the plug cap 412 inside the air extraction pipe 2; As Figure 4 、 5 、shown in Figure 10, when pushing the handle 32 to drive the piston rod 31 to move downward, the third sealing ring 33 is pressed against the upper side wall of the third sealing ring groove 311 under the action of the upward frictional force of the inner wall of the air extraction pipe 2. At this time, the lower end of the air passage groove 313 is exposed below the third sealing ring 33, which is equivalent to connecting the upper and lower spaces of the third sealing ring 33 through the air passage groove 313. At this time, the plug cap 412 is restored under the action of air pressure and its own elasticity and is pressed against the upper surface of the bottom cover bottom wall 221 to seal and block the notch 212. And the air in the air extraction pipe 2 corresponding to the space between the third sealing ring 33 and the plug cap 412 is compressed by the piston rod 31 and discharged out of the bottle through the air passage groove 313 and the air passage opening 312. In this way, part of the air in the bottle can be pumped out of the bottle. After repeating the above operations many times, all the air in the bottle can be pumped out, so that the inside of the bottle reaches a vacuum state.

[0048] And when it is necessary to disassemble and separate the wine stopper from the bottle mouth, as Figure 6 、 7 shown, press the air release rod 51 to slide downward, so that the lower end of the air release rod 51 slides out of the lower end of the piston rod 31 and squeezes the plug cap 412 to deform and open the notch 212. At this time, since the inside of the bottle is in a negative pressure state, the outside air of the bottle will sequentially pass through the air passage opening 312, the air passage groove 313, the notch 212 and the air hole 21 and be discharged into the bottle, so that the air pressure inside and outside the bottle reaches balance, so that the wine stopper can be easily pulled out of the bottle mouth.

[0049] As Figure 1 、 3 、shown in Figure 4, an inner stopper 12 matching the bottle mouth is also provided in the above-mentioned first stopper seat 1. The inner stopper 12 is sleeved outside the air extraction pipe 2. The inner stopper 12 can better seal the bottle mouth to improve the sealing performance of the wine stopper to the bottle mouth.

[0050] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
