Abstract

A hand pressing type vacuum device includes two movable piston sets, a fixed piston set and two compression spring sets, which are arranged in a coaxial manner to drive the suction stroke of the piston. With the design of the different cross-sectional areas of the pistons and the magnitude of the elastic resilience of the spring, it is able to generate the volume change and the suction vacuum pressure of the piston driven by the compressed and exhausted gas and the spring return while being pressed, thereby achieving rapid suction and low negative pressure of the large piston and achieving internal negative pressure environment of middle vacuum level of the small piston. The miniature fixing type piston is operated with three check valve sets to exhaust air and improve the vacuum level. When being designed as a container cover, the device can be a vacuum container for storage. Alternatively, when an extendable sleeve is added, a general plastic bag can be used as a vacuum storage. Alternatively, when being used as a female base sleeved onto the male head of the vacuum pressure-releasing check valve, the device can be used to store the daily supplies economically and conveniently.

Description

   Multipurpose pressing type vacuum generating device and application component   

The invention relates to a hand-held and lightweight pressing type vacuum generating device, which adopts the synchronous working principle of a coaxial 3-layer cylinder. The large piston on the outer layer generates large flow and fast suction to form a low negative pressure vacuum, and the small piston generates low flow and negative pressure. Pressure vacuum and forced exhaust of miniature fixed pistons to improve the design of high vacuum, to overcome the physical characteristics of high expansion when the gas is in a negative pressure environment. And apply a variety of combinations to make it suitable for various types of containers for vacuum storage and storage.

As shown in Figure 42, the conventional hand-pumped one-way air pump must be used to pull the piston quickly and frequently. It is inconvenient to use and the vacuum suction performance is not good. When the piston diameter is large, a very large output is required. It takes a lot of effort.

As shown in Figure 43, the conventional single-cylinder push-type suction device has a piston cross-sectional area that determines the pumping volume, but it also increases the working force of the pumped gas, which can only produce low vacuum results, so it cannot be an effective method. And multi-faceted design approach.

Because the conventional manual air extraction device is difficult to apply to existing daily life simply and effectively, such commodity items are not commonly sold in the market; therefore, the cheap price and simple, effective and convenient application are design concepts of the present invention.

The suction rod is the mainstream in the market. The working principle is to draw the piston to draw air to form a vacuum negative pressure. However, according to the specifications of the market suction rod, the diameter is 40mm. In theory, the maximum pulling force is 12.5kgf. The sub-high-frequency force can overcome the atmospheric pressure in order to approach the theoretical maximum vacuum. However, the suction rod is a hand-held device, and based on the physical characteristics of high air expansion, it is actually difficult to perfect it by simply using a one-way valve piston cylinder structure. To achieve the purpose of vacuum preservation with ultra-low negative pressure, it can only be said to be stored slightly below one atmosphere; and the operation of the suction rod does not conform to perfect ergonomics.

The invention provides a handheld pressing type vacuum generating device which is more in line with the ergonomics of the human body, and uses the synchronous working principle of a coaxial multi-layer cylinder. The pneumatic piston with a large cross-sectional area of the outer layer adopts a free-floating method. After the upper cover is pressed, the spring rebound force exerts the suction force on the cross section of the outer piston, and the back pressure of the atmospheric pressure formed with the vacuum degree will form at any point. Balance is a kind of low-negative pressure balance. The task function is to pump a large amount of air at a time to reduce the number of pressing operations required for a large-capacity container. The inner piston with a small cross-section area combined with the upper cover can rely on a stable and consistent pressing force and set the value of the spring restoring force to make the cross section of the small piston generate a set negative vacuum pressure.

In order to improve the application result of high vacuum, the invention provides a small radial central axis cylinder, and three check valves are arranged on the axis. The mission function is to exhaust the gas at the initial stage and to force the exhaust gas at the later stage to overcome the high air pressure. Expansion characteristics and achieve the set high vacuum negative pressure.

The vacuum generating device of the present invention is an application in which a general plastic bag can be sleeved for short-term vacuum preservation (in the form of economic utilization), and the elastic colloid on the outside of the sleeve provided below can be used in a commonly used plastic bag sleeve. The air-tight locking device achieves vacuum storage and storage that is economically convenient, simple, and practical for short periods of time, and can be carried out for various applications.

The vacuum generating device of the present invention is sleeved with a male and female head, that is, a set of female seats of a pressing type vacuum pumping device can be used, corresponding to dozens of check valve male head applications for economic and practical purposes, and can be sold on the market One-way valve male head leaks when the pressure difference between the inside and outside of the product container is low, that is, the commercially available product simply uses a silicon film as the one-way valve air-tight lock as the main structure. When the pressure difference between the inside and outside is reduced, it is impossible. In the state of airtight maintenance (in the form of economic use), the airtight ring on the inner side of the sleeve provided below is designed as a female connector for fast socketing of the vacuum indicating and pressure relief check valve group male connector. When the male connector of the vacuum check valve group and the bottle, can, box, and bag are combined into a closed container, the vacuum generating device of the present invention can be used to achieve the purpose of economically and inexpensively storing items with high vacuum for a long time.

The vacuum generating device of the present invention corresponds to a small and convenient container or a container that is used many times a day (in a special type), when using 2 sets of springs, 3 piston cylinders, 4 sets of check valves, etc., when combined into a container lid, With the use of various sizes of containers, it can become a variety of dedicated vacuum bottles, vacuum cans, and vacuum boxes, thereby improving the living needs of convenient carrying and storage.

The vacuum generating device of the present invention uses a special type as the lid of the container and is applied to the storage and storage of a larger container. It is equipped with an air-tight reclaiming design and a device that can be manually adjusted or automatically adjusted the invalid space during use. The vacuum generating device of the present invention improves the overall use efficiency in the labor time required to maintain a high degree of vacuum.

The vacuum generating device of the present invention uses a special type as the lid of the container, so that the container can be set as a double layer, which can be a double-layered cup and a box. The commercially available vacuum insulation products are made of the same material as stainless steel. The inner and outer cup box type is welded together at the mouth of the cup box, and the suction port is blocked after vacuuming at the bottom of the cup box. There is a 2 ~ 4mm insulated vacuum space between the inner and outer layers, so there is only the cup mouth during the heat preservation Or the welding at the mouth of the box will leak due to the material's conductive heat energy. The other inner cups or boxes will be in a vacuum insulation state without air, and will not be leaked by the air-conducted heat energy, so it can become a thermal insulation product. The upper cover uses the plastic material to dissipate the thermal energy and keep the contents at a non-high temperature for a long time, which is prone to breed bacteria. The accessories of the present invention can not necessarily be the same material for the inner and outer cups, inner cups, The layer box can be used to hold the beverages, food ingredients or suitable materials to be stored. The inner and outer layers are separated by a gap of 2mm ~ 4mm as the temperature and heat transfer layer, and the inner and outer cups and boxes are supported by a proper number of points. The gap clearance is ensured, and the cover clearance is obtained. In this way, the heat conduction area between the materials can be greatly reduced. The inner layer or the outer layer must be strengthened to resist the atmospheric pressure of high vacuum depending on the application conditions of the material. The device can suck the air in the airtight closed space inside the outer layer and the upper cover, and strengthen the storage and storage environment into a composite function of vacuum insulation, cold preservation, and freshness preservation, which will further provide the needs of carrying around in life, and more convenient Safe and hygienic diet and food preservation environment, and can use various transparent materials for vacuum insulation, cold preservation and freshness, to enhance the safety, convenience and fun of life.

Press type high vacuum degree generating device 20, please refer to the first figure, the sixth figure, the seventh figure, and the eighth figure. The present invention provides a device which is convenient to operate and can save effort and high vacuum degree, and includes a main body 3 and a small cover. Piston 1 and spring 10 with air-tight ring 8-1, check valve 9-2, one-way exhaust valve 9, large piston 2 and spring 11 with air-tight ring 8-2, 8-3, miniature central fixed shaft piston The rod 6 and the supercharging exhaust check valve 9-1, the central shaft lower cover fixing ring 7 and the vacuum extraction check valve 9-3, a total of 5 groups of components are combined into a push-type vacuum extraction device; Multi-purpose target, add a cylindrical shape 3-23 solid extension below the main body 3, and install elastic silicone 5 below the outside of the extension tube 3-23, install a plastic bag sleeve 4 above the outside of the extension tube, and extend the airtight ring 8 inside the barrel Used as airtight when the male and female heads are docked; when not in use, press the upper cover 1 down to the bottom and rotate clockwise to the right. At this time, the 1-2, 3-3 card slots will play a limiting role as shown in the eighth figure; At the beginning of use, turn the top cover 1 counterclockwise to the left and the top cover and the large piston pop up as shown in the sixth figure, that is, the limit stops after contacting 1-2 and 3-2 as shown in the eighth figure; Before starting to press the upper cover 1 to the bottom position, during the process, the air in the original internal space of the air chambers 14 and 15 is blocked by the check valve 9-3 and discharged through the check valves 9-2, 9-1, 9 in sequence, and the air chamber 17 Because the piston 1 moves downwards, the relative check valve 9-1 does not move, so the air chamber 17 gradually reduces the space and has the effect of lifting the air pressure until the check valve 9 is discharged. When the upper cover 1 is pushed down to the end, please review the eighth figure, At this time, the space of the air chambers 14-2 and 15-2 is minimized. The purpose is to reduce the air remaining in this space when the next pumping cycle is started, and the piston 1 and the piston 2 suck and expand, which further affects the suction efficiency. When the pressing force of the hand of the upper cover 1 is released, the piston 1 and the piston 2 cause the piston 1 and the piston 2 to suck up the air due to the restoring force of the compression spring 10 and the compression spring 11, and return to the sixth figure, via the air chamber 12, The air extraction check valve 9-3, the air chamber 13, the air chamber 14, and the air chamber 15 complete one air extraction and exhaust cycle at this time. Examining the seventh picture, after completing multiple cycles, when the next pumping task starts, 14-1, 15-1 already have a vacuum degree, which represents that the air in the air chambers 14-1 and 15-1 has been low and medium. Expansion, but because the cross-sectional areas of piston 1 and piston 2 are different, the difference in atmospheric pressure between the two is nearly 5 times. At this time, the compression spring 11 of piston 2 cannot be borrowed due to the back pressure of the atmospheric pressure. The piston 2 is rebounded and lifted by the restoring force of the compression spring 11 and stays at the equal pressure position of any cylinder. As the vacuum of the operating piston 1 increases, the negative pressure gradually increases. The positive pressure of the cross-sectional area on the piston 2 is equal to or greater than the atmospheric pressure. The return force of the compression spring 11 makes the air chamber 15-1 tend to be the smallest. For example, it is difficult to increase the vacuum degree by simply performing the suction action on the piston 1 and the piston 2. All the movements only leave the air physics of the air chamber 14-1. It expands and recovers at the same time. At the same time, the action of pressing the upper cover piston 1 simultaneously drives the check valve 9 and check valve 9-2 to move down. The check valve 9-1 does not move and pressurizes the space of 17-1. 9 For the purpose of exhaust, during the process 16-1 expands the space and is pushed into by the air chamber 14-1, 15-1, or by a single Air is sucked into the valve 9-1, so when the upper cylinder piston 1 is lifted up after the hand is released and pressed, the gas in the space volume of the air chamber 16-1 and the air chamber 17-1 is made by the micro one-way valve piston 9-1. Out exchange, at this time, the upper cover 1 of the suction device is pressed down. Due to the relationship between the external atmospheric pressure and the internal vacuum negative pressure, the pressure difference has been the return force of the drop spring 10, and only a very small spring return will be felt at this time. According to this cycle, when the upper cover 1 is pressed by the hand, the pressure of the air chamber 17-1 can be quickly and labor-saving by the minimum cross-sectional area piston 9-1 without increasing the hand pressing force load, until the atmospheric pressure is greater than 1 The exhaust is compulsorily exhausted via the exhaust check valve 9 to increase a higher vacuum.

The press-type intermediate-level vacuum generating device, please refer to the ninth figure, the present invention provides a vacuum pumping generating device which is convenient to operate and can save the demand of intermediate-level vacuum. It includes a main body 3, a small piston 1-5 and a spring 10 With check valve annular rubber ring 9-4 and one-way exhaust valve 9, large piston 2-1 and spring 11 with check valve annular rubber ring 9-5, 9-6, lower cover retaining ring 7 and check valve 9-3. A total of 4 sets of components are combined into a press-type intermediate vacuum pumping device. The operation mode of this press-type intermediate vacuum pumping device is the same as that of the press-type high vacuum generator of the embodiment [0014], and the related parts are configured differently. The points are as follows. When the upper cover piston 1-5 is pushed down, the large piston 2-1 is pushed down at the same time. The air chambers 14-3, 15-3, and 13-3 in this area communicate with each other. The loops 9, 9-4, 9-5, 9-6 are directly discharged. When the hands are not pressed, the piston 1-5 and piston 2-1 start to inhale due to the rebound of the compression spring. After several times of inhalation, The air chambers 14-3 and 15-3 already have a vacuum degree of negative pressure. When this vacuum degree of negative pressure is changed by the volume drawn by the piston 1-5 due to the rise of the spring, it can only be the air chambers 14-3, The physical expansion and recovery of the negative pressure air in 15-3 and 13-3 will not increase the vacuum negative pressure at this time, that is to say above the one-way valve ring rubber ring 9-4, 9-5, 9-6 Withstand an atmospheric pressure at any time. When the compression spring is restored and pressed down, the air in the air chambers 14-3, 15-3, and 13-3 cannot be compressed to a pressure greater than one atmosphere, that is, it cannot be discharged, so the degree of vacuum It cannot be lifted, so this is a press-type intermediate vacuum generator.

Please refer to the second, third, fourth, fifth, eighth, tenth, eleventh, twelfth, thirteenth, In the fourteenth figure, the present invention provides a short-term and convenient low-vacuum storage and storage application form. As shown in the eighth figure, the plug 62 is inserted into the air chamber 12-1 of the pressing vacuum generating device, as shown in the tenth figure. Put the plastic bag 60 and the opened plastic bag opening far side 60-1 into the soft elastomer silicone 5 applied in the plastic bag. As shown in Figure 11, the upper edge of the plastic bag opening far side 60-1 is put into the two sides of the plastic bag. The inner side of the folding board 59, after the two sides are hung in, the other side of the opening of the plastic bag is 60-2. From the outer side of the folding board 59-1 on both sides, it is folded around the center of the silicone 5 and wrapped around the outer side of the folding board 59-1. As shown in the twelfth figure, hold the airtight ring 5-1 or the clamping pad 5-2 with your fingers to prevent loosening, and use your other hand to gradually pull down the upper plastic bag closing sleeve 4 to the locked position, such as The 4-2 position shown in the fourteenth figure. If you examine the thirteenth figure, you can see that in the first process, the inner side of the closed sleeve 4-1 will be produced with the arc 5-4 on the clamping claw first. Interference, forcing the front tip 5-3 of the clamping claw to press the plastic bag 60 wrapped around it and continuously pressing the supporting clamping pad 5-2 below it, generating a deformation interference pressure of the front tip 5-3 to become a plastic bag The strong clamping force of 60, as shown in the fourteenth figure, forces the neatly wrapped plastic bag 60 in the second process, and interferes with the external pressure of the airtight ring 5-1 twice, and interferes with the outside It is airtight and sealed. Thereafter, the internal space of the plastic bag 60 only communicates with the air chamber 12-1 as shown in the eighth figure. As shown in the fourth and eighth figures, when the vacuum generating device of the present invention starts operating, the inside of the plastic bag 60 Air is exhausted to the outside through the air chamber 12-1, the exhaust check valves 9-3, 9-2, 9-1, and the check valve 9. In order to prevent the soft plastic bag 60 from being trapped in the air chamber due to the suction force during the process 12-1. Before inserting the plastic bag 60, insert the blocking member 62 in advance, and suck the air in the plastic bag 60 through the thin groove above the blocking member 62. After the air in the plastic bag 60 is sucked, the plastic bag 60 will In a dry state, as shown in the fifth figure, the plastic bag 60 will fit on the surface of 62-7, and it will show a convenient hanging type body with buckle pull-in points 62-3 ~ 62-6. At this time, Provide two kinds of operation countermeasures, one of them: as shown in the second figure, to seal the plastic bag airtight ring buckle 52, as shown in the third figure, fix the C-shaped inner edge 52-4 on the concave side of the concave side and hang it in The soft silicone airtight tongue 52-3 is fastened along the two sides of the clip 52-6, so that the soft silicone airtight tongue 52-3 and the sides 52-6 are clamped, and the plastic bag 60 is placed on the tongue 52- 3 The upper and lower sides are clamped airtight by 52-6, until the snap-on movable member 52-2 is inserted into the snap-in holder 52-1 to complete the airtight lock. After the airtight ring 52 of the plastic bag is locked, as in the fourteenth As shown in the figure, the position of the closing sleeve 4-2 is lifted upwards to release the airtightness produced by 5-1, and then to release the interference clamping of the clamping claw 5-3 as shown in the thirteenth figure, which can be easily removed. The vacuum-treated plastic bag with contents, as shown in the third picture, only needs to press the buckle to unlock the pressing point 52-5 when it is opened, until 52-2 is released from 52-1, and it can be opened to take out the contents of the plastic bag. Secondly, as shown in the fourteenth figure, the rubber band 61 which has been hung into the outermost bottom of the plastic bag closing sleeve 4-2 in advance is pulled out with one finger and then hung down the plug 62-2 plane circle.

The stopper seat of the vacuum indicating pressure relief joint 18 for quick and easy socket connection, please refer to FIG. 15, FIG. 16, and FIG. 17. As shown in FIG. 17, the present invention and the application embodiment provide a simple A three-dimensional illustration of the vacuum bottle stopper storage application and method; as shown in the sixteenth embodiment, including the pressure relief joint 18 by the body 22, the vacuum degree indicating ring is the pressure release button 21, the spring 25, the inner and outer ring The leak-proof elastic member 23 and the limiting rod 26 of the ring are composed of screws 21-1 interlocking the pressure-relief pressing button 21 and the limiting rod 26, O-rings 8-18, and the plug body seat 22-2 has a joint 18 insertion holes 22-12 Built-in filter paper 3-20, the outer ring is sleeved with a leak-proof elastic pad 24; when it is connected with a vacuum pumping device to suck air, as shown in Figure 15-1 of Figure 15 The inner and outer ring leak-proof elastic member 23 will rise due to the pressure difference. The air ring 23-1 of the elastic member shown in 18-3 and the main body 22 slope will create a gap 22-3, and the air will be sucked. Ascending and rising, the spring 25 is thus compressed. When the suction of gas is stopped, the elastic member 23 returns to its original position due to the return force of the spring 25, and once again becomes air-tight and locked. When the air device is removed, it is kept in a vacuum state, such as 18-2. At this time, the internal pressure of the container 27-2 is much lower than the external pressure 27-1. At this time, the atmospheric pressure difference is given a relative downforce according to the cross-sectional area of the limit rod 26. The position rod 26 moves downwards and the vacuum degree indicating ring 21 is pushed down, causing the compression spring 25 to change to generate a restoring force, and finally balance it at a certain position. Use this stay position to judge the high, medium and low vacuum degrees according to the pressure scale ring 22-4 The value is as shown in 18-4. When you want to release the vacuum storage and access the contents of the container, you need to press the vacuum degree indicating ring at this time to press the button 21 for pressure relief to the end. 26. There is a pressure relief groove at the upper edge of the limit lever 26. As shown in Figure 18-6, outside air passes through the inner ring air tight ring 23-2 of the inner and outer ring leak-proof elastic member 23 and the limit lever. The upper edge groove 26-3 enters the internal space 27-2 through the ventilation path 22-1, and the internal and external equal pressure is obtained at this time; this architecture design does not show poor air tightness due to the internal and external pressure difference. Completely improve the low-vacuum leakage state of commercially available products. The force application ring 22-8, the outer side seat 22-7 of the bottle mouth is longer than the stopper at the hand plug, which reduces the pollution caused by plugging and placing. If so, when the assembled vacuum stopper is finished, it is sealed with a silicone elastic ring pad 24. When inserted into a wine bottle, a press-type vacuum generating device can be operated to suck the air in the bottle into a vacuum storage state.

It is assembled by using the device of the vacuum indicating pressure relief joint 18, which is convenient and free of pulling out the stopper. Simply pull the vacuum stopper sleeve 57 and pull the slide sleeve to pour out the vacuum stopper device for wine. Please refer to the eighteenth and nineteenth diagrams. As the nineteenth diagram is a three-dimensional illustration of the present invention and its implementation, it provides a convenient combination of vacuum storage and retrieval modes without removing the stopper. Figure 18: Contains a liquid stopper holder 56 and a pull-out stopper 57 for the vacuum stopper. When the stopper silicone gas-tight ring gasket 24-3 is inserted into the container wine bottle 27, an air-tight seal is formed. The pressure of 27-2 in the container wine bottle will be slightly increased, and the extra gas pressure will push up the inner and outer ring leak-proof elastic member 23 to be discharged. At this time, the combined parts in the upper cover sliding sleeve 57 support the O-type in the sliding path. Ring 8-13 and sliding path air-tight O-ring 8-14 and the inner wall 56-2 of the sliding sleeve are hermetically sealed. Between the two paths O-ring 8-13 and 8-14, there is an opening 57-1 and Air path 57-2. At this time, the internal cavity 57-4 communicates with 56-3 and 27-2. The overall gas seal is present. At this moment, you can use the push-type vacuum generating device sleeve to connect to the sliding sleeve 57. The vacuum indication and pressure relief check valve sucks gas for vacuum storage. After the pressure is increased for multiple times, the pressure type vacuum generator can be removed and stored. When it is desired to be used, its vacuum indication pressure relief joint is operated. Is exactly the same as the above (embodiment [0017] vacuum indicating pressure relief joint 18). After the pressure is released, the upper cover sliding sleeve 57 pulls up the sliding guide plate 57-6, and the bottom is locked at the limit point. At this time, the sliding path is The air-tight O-ring 8-14 and the inner wall 56-2 of the sliding sleeve are still tightly sealed. The sliding path supports the O-ring 8-13 and the inner wall 56-2 of the sliding sleeve to be partially separated from each other, forming a drink channel opening. 57-1 communicates with the pouring glass outer cup mouth 57-1, and the gas passage opening 57-2 communicates with the gas passage groove 56-4. At this time, the wine liquid in the container is passed from the bottle 27-2 in the container via the stopper. The channel 56-3 to the inner cavity of the bottle stopper passage 57-5 is then discharged from the channel opening 57-1 and then through the outer cup opening 56-1. At the same time, the gas outside the bottle communicates with 57-2 through 57-5 Then enter the bottle through the 56-5 vent gap to replace the volume of the decanted wine. 27-2. When you want to store and pull or push down the sleeve 57-6, the outer cup mouth dust cover 57-3 is closed at the same time. Cup mouth 56-1, sliding path supporting O-ring 8-13 and inner wall 56-2 of the sliding sleeve are completely airtight again, so that users can quickly and conveniently use vacuum storage and retrieval, eliminating the need for pumping The laborious action of pulling and pressing the stopper. When it is time to replace the bottle, remove the wine stopper and place it arbitrarily. Because the edge protection base 22-7 is longer than the silicone rubber 24-3, the bottle can be protected from contamination.

The use of a press-type vacuum generating device is combined into a convenient type to avoid the pull-out of a press-type vacuum generating stopper. Please refer to FIG. 20, FIG. 21, and FIG. 22, which illustrate the present invention and its application. It provides a more convenient mode combination of vacuum storage and retrieval of self-exhausting and unplugging stoppers, as shown in the twentieth diagram of the implementation diagram; including the convenient mode as described above (the embodiment [0018] (Without pulling out the stopper) The same part of the description and operation will be explained. This embodiment will explain the differences. The push-type vacuum generating device is combined with the stopper base 56. The O-ring 8-13 is hermetically sealed from the outside because it is in an air-tight position. After pressing the vacuum generating device, it is in the state of vacuum storage. As shown in the figure 21, when you want to take the contents of the bottle, press the pressure relief plate 8-11, through the pressure relief plate rotation center hole 56-7 of the base 56 according to the lever The principle, the other end of the position of the pressing plate 8-11 is lifted by hand to pull up the conical air-tight plug 8-16. The combination of the two is because the pressing plate 8-11 is a larger hole and the air-tight plug 8 -16 fits the smaller mandrel, so the airtight plug 8-16 can float in the larger hole, The conical airtight head is automatically aligned with the centerline position of the pressure relief hole 56-6 in this way, and the external air enters through the pressure relief hole 56-6. At this time, the inside and outside of the bottle are at equal atmospheric pressure, and the upper cover is pulled up by the upper cover 1 or the main body 3. The seat 57, after being pulled up, the O-ring 8-13 is turned into an open position, and the wine outlet 57-1 and the air flow channel 57-2 are formed to be open to the outside. Limit guide 57-6 limit, go back to the twenty-first picture to review, you can pour out according to the wine pouring path 56-3, 57-5, 57-1, 56-1, gas from 56-4, 57 -2, 57-5, 56-5 enter 27-2 to fill the volume of the wine that has been poured out. If you want to store and store, push the slide 57 into the fixed wine stopper 5 6 by the upper cover to promote the O-ring 8- After the 13 turns to the airtight position, the counter top is turned counterclockwise to eject the upper cover to extract air. During the process, the anti-rotation stopper 56-8 and the anti-rotational reinforcement rib 57-7 maintain the same relationship between the two angles.

It is air-tight when in contact with the plane. When the seal 38 is purchased and started to be used, the cylindrical locking member 3-10 with the internal thread 3-12 is locked into the bottle 27, and it can be discarded and removed. The supporting semi-circle 19 is pushed down from the top of the upper cover 1. At this time, the outer cylinder wall 3-5 of the piston 2 of the main body moves down the air-tight ring 39-1 of the silicone ring 39 to the limit position 3-6. Until the limit 3-6 fits tightly on top of the silicone ring 39-3, make sure it is airtight. During the process, the air in the bottle 27-2 will be lowered by the cover 7-1 and the main body 3-5 times. Move to cause the 27-2 in the bottle to be squeezed to increase the internal air pressure. At the same time, the increased air pressure will be sequentially discharged from the check valves 9-3, 9-2, 9-1, 9 to the outside until In the twenty-ninth picture state, you can prepare for vacuum evacuation at this time, and press the upper cover 1 down. At this time, the external linkage teeth 3-25 and the internal linkage teeth 3-26 are connected in series, and the upper cover 1 is rotated counterclockwise to the left. And because the built-in two sets of compression springs 10 and 11 are ejected due to the restoring force, the air in the bottle 27-2 is sucked at the same time as the ejection. The next operation is the same as the description provided in the above embodiment [0014]. By After several operations, when it no longer rebounds quickly, it means that the restoring force of the spring 10 of the upper cover piston 1 and the atmospheric pressure applied to the cross-sectional area of the piston 1 tend to balance, that is, to reach the preset vacuum Degree range At this time, the upper cover 1 is pushed down to the bottom and turned clockwise to the right to lock. This is to achieve a vacuum storage state. When you want to retrieve the contents of the bottle 27, unscrew the cylinder 3 of the locking mechanism counterclockwise. -10 hours, using the labor-saving features provided by the thread gradient (only suitable for small-area press-type vacuum caps, that is, the inside diameter of the bottle mouth is about 10cm, which facilitates the design of the internal thread gradient operation), silicone ring After the mounting plate 3-11 is turned left due to the left-hand rotation, the tightness of the silicone rubber ring 39 disappears and the silicone rubber 39-2 is restored to produce a wavy shape. A gap is created, and the air vapor penetrates between the internal threads. When the airtightness is lost, the screw cap 3 -10 to unscrew the contents.

For an example of the top cover assembly of the press-type vacuum generating device, please refer to FIG. 30. The present invention and the implementation example are applications for providing vacuum storage bottles and cans for the press-type vacuum generation top cover combination. The seal is directly sealed by the push-type vacuum upper cover and pumped through the one-way valve 9 to be packaged for shipment. It does not need to increase the cost of the desiccant or deoxidizer. It has the function of reducing waste.

At this time, the wavy silicone ring 31-3 between the bottle and the mouth of the container is changed to the contact plane air-tight due to the screw-locking squeeze type. Position type. In the process, after the product is placed in the container 27, the manufacturer locks the press-type vacuum generating device according to the internal thread. The gas pressure in the bottle 27-2 is increased by 9-3, 9-2, 9-1, 9Sequential discharge, followed by the production line The suction head of the automatic machine suction equipment is placed on the exhaust check valve 9 in the center of the upper cover, and the suction is directly formed to form a low-pressure, low-oxygen, 27-2 vacuum storage in the bottle, a moisture-free storage environment. In order to prevent the upper cover from bouncing when left-handed, the upper cover 1 and the main body 3 are limited. Therefore, the internal thread can be rotated upwards. At this time, the wavy silicone ring 31-3 returns to its original state, and the air generated by the gap is penetrated between the internal threads. When the sound of air infiltration is heard, it means that the bottle has lost its airtightness. Turn the upper cover 1 to the left to easily unscrew the contents.

For an example of the top cover assembly and pressure relief member of the press-type vacuum generating device, please refer to FIG. 25.

During the process, the increased air pressure in the tank can be discharged to the outside by the pressure-relief air-tight plug shaft 8-10 or from the check valve in order from 9-3, 9-2, 9-1, 9 to the outside. To prepare for vacuum storage, that is, to rotate the upper cover 1 counterclockwise to the left until it pops up by itself. Due to the built-in 2 sets of compression springs, the upper cover is driven The piston 1 and the floating large piston 2 start to suck the air in the bottle and can. When the upper cover 1 floats to the top, the upper cover 1 is repeatedly pressed to the bottom position. After multiple pressings, the compression spring 11 of the floating large piston 2 has the restoring force and the bottle. The vacuum negative pressure inside the tank 27 forms an equilibrium state staying at any position. With the increase of the vacuum negative pressure, the relevant details are the same as the description provided in the above embodiment [0014]. When you want to open the container 27 to access the contents At this time, pressing the pressure-relief automatic reset platen 8-11 will pull out the air-tight plug 8-10 and squeeze the compression spring 8-9 to drive the air-tight plug shaft 8-10 and the small air-tight silicone ring 8-7. In the airtight state, at this time, the external negative pressure causes the external air to enter the bottle and can 27, and the pressure is equal to the internal and external moments. Then, the bottle and can 27 can be easily separated to combine with the upper cover to access the contents.

As shown in the enlarged illustration of 66-3 in Figure 34, the silicone 65 and the inner cup 67 follow the wave. When the interference type is pressed to form a negative pressure, the airtight 65-2 is enlarged as shown in 66-4, and the airtightness is supported by the lower side wall of the link ring 66. A bottle is set up at 3-15 at the mouth of the upper cover body. Stopper cap 22-6; Examine the 33rd figure, the stopper cap 22-6 is a vacuum indicating ring and a pressure relief check valve 18, with a pressure relief button 21 on the top, and a leak tight ring 24-2 on the bottom. In this way, after the stopper cap 22-6 is inserted, the inner space 27-2 of the outer cup is a sealed space after being combined with the inside of the main body of the upper cap. At this time, vacuum extraction can be started and the upper cap 1 can be unscrewed counterclockwise, with a built-in spring. At 10 and 11, the pop-up was returned, and the upper cover piston 1 and the large piston 2 started to pump. After several times of pressing, the vacuum of the inner space of the bottle 27-2, 27-3 increased synchronously, and the gap 27-3 between the inner cup 67 and the outer cup 68 Form a temperature insulation layer. The liquid beverage inside the inner cup 67 has a freshness preservation effect due to the vacuum, low pressure and low oxygen environment. Press the upper cover 1 to the bottom, and turn the upper cover clockwise to lock it for short-term storage. When you want to drink the beverage in the bottle, press After lowering the pressure release button 21 in the stopper cap 22-6, at this time 27-2 is the normal pressure after the pressure is released. 27-3 is pressure-reduced but due to the check valve 64-1 Therefore, the vacuum state is still maintained. Fingers can open the can 22-22 and follow the rotation center pivot point 63-1 of the bottle cap revolving arm 63-1 as shown in the thirty-fourth figure. Set on the outer circumference of the cup mouth extension. The arm can be hard plastic or soft silicone. When you drink, drink according to the mouth of the bottle 3-15 and drink it up. At this moment, the press-type vacuum double-layer cup flows out of the liquid beverage, and the air enters the bottle from the mouth inlet 3-16. When you want to temporarily store the lid, close the cap 22-6, unscrew the upper cap 1 counterclockwise, and press the vacuum again. At this time, because 27-3 is still in a high negative pressure vacuum state, only 27- 2Without the space for beverages, quickly obtain the low-pressure and low-oxygen fresh-keeping and anti-oxidation in the bottles and cans and the preservation environment that is not lost by cold or heat.

Refer to Figure 35, Figure 36, Figure 37, Figure 38, Figure 39 for examples of automatic adjustment of the use volume of the top cover of the press-type vacuum generator with a large-capacity container. The present invention and embodiments provide the application of a combination of a press-type vacuum generating device and a top cover of a pressure relief valve with a large-capacity storage box to achieve the purpose of vacuum preservation. As shown in Figure 35, an O-type is set on the press-type vacuum generating device. Ring 8-5, upper cover combination includes upper cover 69, detachable push-type vacuum generating device insertion holes 3-21 and exhaust vent holes 3-22 and filter paper 3-20 placed on the exhaust holes, the vacuum indicates the pressure relief ring 18, strengthened The rib lifter merges 69-1 with the anti-rotation key slot 3-19, and the upper cover airtight rubber ring 8-6 into the upper cover combination. As shown in the thirty-sixth figure, there is a piece in the container 70 that can float up and down. Base plate 73, the shape and dimensions of the outer edge of the base plate 73 are matched with the shape of the inner cavity of the lower part of the container and a clearance of 1 mm is provided. A ring-shaped groove is set on the upper and lower sides of the outer edge of the base plate. -1, air-tight seal installed in the annular groove below The ring 73-2, the retaining ring 73-1, and the sealing ring 73-2 keep the bottom plate seat 73 air-tightly sliding up and down inside the container 70. A bottom table 73-5 is arranged below the middle of the bottom plate seat 73, and the lower side is reinforced. Ribs 73-6, floating rods 74 on both sides, rotation center fulcrum 73-3, ratchet teeth 74-1 below the rotating floating rod 74, and a spring hook rod at about 3 ~ 5cm above it for stretching the spring 75 hanging, the other side of the spring hooked to the bottom of the container hook bar 70-3, two corresponding floating rods 74 due to the weight of the base seat and the spring tension normally make the ratchet 74-1 and the bottom of the container 70 fixed teeth Row 70-2 fits; as shown in the thirty-fifth figure, when it is in the starting state, open the upper cover and pour the grain white rice. Assuming that the white rice poured in accounts for about 9/10 of the volume of the container 70, then the upper cover 69 is closed. Combination and integration (including pressing type vacuum generating device and vacuum indicating ring); as shown in Figure 36, start pumping preparation, open the upper cover 1 left, start pressing to the end, and after several times of pressing, the vacuum will increase, and the atmospheric pressure will push up the bottom plate. The seat 73 floats up (similar to the sliding of a piston), and the white rice carried on the bottom and the bottom plate seat will be pushed up to the bottom 69-2 of the upper cover 69 Stop; but suppose that the white rice poured in only takes up 2/5 of the container space, which means that the volume of air in the remaining space is extremely large. It will be a hard work to lift the air with a press-type vacuum generator. Examining the thirty-sixth figure, the upper cover at this time After the 69 is closed and sealed, you can use both hands to hold the soft silicon tape 80 on both sides of the container 70. The thumbs of both hands are supported on the support plates 70-4 on both sides. Quickly pull up the soft silicon tape 80 on both sides to lift the base plate seat. 73 and the uppermost layer of white rice carried to a position close to 69-2 at the bottom of the upper cover, and then the use of a press-type vacuum generating device was started. At this time, the space volume of the unloaded white rice inside the container 70 tended to be the smallest, so the vacuum degree was increased. The load of pressing times can be quickly increased by pressing a few times. Therefore, this procedure can improve the operating efficiency. After the white rice in the container is stored in a vacuum, the area where the white rice is located is the upper concentrated area 73-7; In the seventh picture, due to the feeding relationship between the inclined plate 73-5 of the inner groove of the base plate and the right dump bucket 71, the storage and storage of white rice will slide to the right hollow cylindrical dump bucket 71; Gate 71-1 The upper part is as shown in Figure 79 in Figure 79 and is restricted by the limiting projection 72-1. When you need to retrieve the content, rotate the rotary table 72 by about 190 degrees from top to bottom. At the same time, it is also restricted by the limit projection 72-1, as shown in 79-2, that is, the white rice in the hollow rotating unloading bucket can be unloaded freely in the rice washing basin below. -1 can see the rotating airtight sealing strips 78, 78-1, 78-2 (shown in 78, 78-1, 78-2 and the O-rings on the upper and lower sides of the AA cross-sectional view are the same one-piece integral molding The air-tight silicone parts are connected at the opening of 71-1 in Figure 79. Both sides of the hollow bucket 71 are sealed by the air-tight ring 8-17 of the turntable and locked by the screws 72-3. Restricted left and right, it can only be rotated and cannot be shifted left and right, and does play the process of reclaiming and discharging without bringing in too much air.) When the 79 is shown in the diagram, the rotating unloading bucket 71-1 is on the top, and the sealing strips 78, 78 -1, 78-2 all have a sealing effect. When the discharge bucket rotates to the angle shown in 79-1, 78, 78-1, 78-2 all play a sealing role in the process, and finally stop at the discharge position. When 79-2 is shown, 78-1 and 78-2 are dense. The strip has a sealing effect, so it can be known that when the white rice is taken out, the volume of air in the hollow cylindrical rotating take-out and dump bucket 71 will be brought in once, so when it is taken multiple times at the same time, the air will be brought in to release the pressure. Figure 36: At this time, the bottom plate seat 73 will gradually lose the vacuum degree, and the positioning teeth 74-1 under the floating rod during the lowering process will catch the fixed rack 70-2 of the container base to limit the downward movement. At this time, when you want to return to the original vacuum degree, you can choose to lift the soft silicon tape 80 on both sides to make up for the volume occupied by taking a lot of white rice, or directly use the press-type vacuum generator to increase the vacuum degree to raise the base plate seat. 73. Because of the difference in height converted by the volume occupied by white rice that was lost after a small amount of consumption, if a family of two people only needs to take white rice once per meal, the vacuum in the concentrated area 73-7 will only decrease to a limited extent. The vacuum generating device can be pushed to the original vacuum degree by pressing it several times. When you want to know the vacuum level, you can observe the vacuum degree indicator button 21. When a small amount of white rice or grains is left in the container 70, it will be concentrated in the middle of the bottom plate base. Inner groove discharge oblique On 73-5, the discharge gate 73-4 is automatically opened and leaked at the end, as shown in Figure 37. (The purpose of setting up the discharge gate 73-45 is to increase the internal volume. The height can be smoothly moved up and down, so in order to obtain the volume in the base plate, a slope 73-5 is set up and the gate 73-4 is used to reduce the friction of the grain being moved up and down. For cereals, press the pressure release button 21 as shown in the thirty-fifth figure, and after removing the upper cover 69, examine the thirty-seventh figure to the right to rotate the manual lever knob 77 of the 90-degree stretcher 76, as shown in the third Figure 18: At this time, the propeller cam blade 76-1 is elevated, and the central cylinder 74-2 of the positioning rod of the floating rod is simultaneously raised, and the positioning rod 74-1 of the floating rod is separated from the fixed tooth row 70-2 below. At this time, the white rice grains are poured in. As the total weight is increased, when the load of the tension spring 75 is exceeded, the base plate starts to fall according to the accumulated load, and returns to the initial use situation shown in Figure 35.

For an example of an adjustable volume combination of a press-type vacuum generating device with a large-capacity container, please refer to FIG. 40 and FIG. 41.

When both sides are pressed down at the same time into the 82-9 shape, the upper cover fixing seat 82 is lifted up, and the air-tight silicone ring is lifted from 82-5 Before before lifting up to 82-5 After detaching. The mouth of the glass bottle is convenient for taking off the upper cover fixing seat 82, and taking or putting the storage items in the glass bottle can, as shown in Figure 40. Suppose that all the Chinese medicine wolfberry is started to be put. 2/5 total height, lift hands 82-7 Place the adjustable volume upper cover holder 82 into the glass bottle jar 81 and press it down from above to ensure that the sealing ring 82-5 enters the glass bottle jar 81. At this time, the maximum effective volume space is 81-2, and the adjustment ring 83 And the mounting seat 84 is at the highest position, that is, the position where the maximum volume is 83-8 and 84-8. It is found that the Chinese medicine wolfberry only accounts for 2/5 of the air space in the bottle 81, and the volume in the container can be adjusted. Effectively improve the aging time of vacuum preservation. Rotate the blade 83-6 clockwise to the right to move the adjustment ring 83 and the internal pressure-type vacuum suction device mounting seat 84 down until the outer upper limit position 83-5 is close to the inner lower limit position. 82-4, then adjust the suction device mounting seat 84, and with one hand, spread the rotating rib blades 84-7 until the outer upper limit position 84-5 is close to the inner lower limit position 83-4, as shown in the figure 41. At this moment, it is the minimum volume. At this time, the lowest position of the adjusting ring is 83-9 and the lowest position of the mounting seat is 84-9. During the volume adjustment process, as shown in Figure 40, the internal air in the maximum space 81-2 in the bottle, The adjustment process will be compressed and boosted. When the air pressure starts to increase, the check valve 9-3 will be pushed in sequence. , 9-2, 9-1, 9 and exhaust air from the check valve 9 (refer to the sixth figure), or from the outer ring of the leak-proof elastic member 23 below the vacuum indicating ring 21 (refer to the fifteenth figure) 18-3), keep the pressure inside and outside of the glass bottle and tank at all times. At this time, the shape of the large container with adjustable volume and lid combination operation is as shown in the forty-first illustration. At this time, the shape is only about 1 of the maximum volume of the edge. / 2, start to prepare for vacuum storage and storage. Refer to the fortieth figure.
