Description

Nonlinear check valve structure

The invention provides a non-linear check valve structure, in particular to a gas stop valve for an air seal body which can greatly reduce gas backflow, in particular to an inner film of a gas stop valve, and relates to an air inlet, an air outlet, an arc of an inner membrane and gap.

According to the air sealing body, there is a gas bag for packaging and a gas bag for buffering. The air sealing body is generally provided with a one-way air check valve for inflation, and the air sealing body is automatically closed after being inflated through the air stop valve.

It is also known that the conventional air sealing body is developed into a continuous one-way air check valve and is disposed in the continuous air column, that is, a state in which one air can be inflated so that each individual air column can be in the air, and the air check valve is utilized After entering the air, it can automatically close the air. This continuous one-way air valve brings the inflated air column into the industrial use, which becomes the buffer package of the product, which can be used in transportation or storage, such as the US NO.2007-02670941A And the patent case of NO.2003-10-610501 and the like is disclosed.

However, the above structure also shows a serious disadvantage that the one-way gas stop valve can be closed, but the time for locking the gas in the air column of the air seal body by the gas-closing ability cannot be sustained, that is, the air inside the air column cannot be blocked. The original path entering the air column is returned to the outside atmosphere, so that the air in the air column of the air sealing body slowly unknowingly scatters to the outside, causing the air sealing body to degas and lose the buffer function.

A detailed comparison of the problems of the prior art.

1. In the U.S. Patent No. 2003-3329777BZ patent, the one-way air check valve structure uses a lower end heat-sealed arrow-shaped grain for the purpose of diverting gas from the arrow into the air-tight body, and if the air is recirculated, it is bottomed. Blocked, but still maintains linearity at the split, that is, a straight path, which causes the gas in the airtight body to flow back.

2. In the US Patent No. 2003-10-610501, it is disclosed that the one-way valve adopts three-stage control, that is, an inlet, an intermediate diverting section and an outlet section, but the connection between each section and each section must still be maintained. The linear path allows air to enter, and because of the linear path, air can flow back to the outside through this linear path.

3. In the U.S. Patent No. 2003-0094394A1, a linear blocking gas stop structure is proposed which adopts a cross type to leave a gap at the end of the straight path, allowing air to enter the next layer from the gap and immediately block the lower layer. Forcing the air to turn to the other end of the gap to continue to advance, the purpose is to make the backflow air back into the gap and then be blocked, resulting in difficulty in returning to achieve the effect of closing the gas, but its structure adopts linear blocking and straight turning, violating the theory of fluid mechanics. Extremely unsatisfactory when inflated.

4. In the US Patent No. 2007-0267094A1, the structure of the gas stop valve with a wide inlet and a narrow middle and a widening at the gas outlet is proposed, but the linear or straight path is still used, and it is still impossible to get rid of the air circulation. The problem of the path returning to the outside world. Therefore, the above problems are in urgent need of improvement.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a gas sealing valve for an air sealing body which can greatly reduce gas backflow, thereby overcoming the above-mentioned prior art, a linear path in which a conventional air check valve easily enters and returns to the outside, resulting in difficulty in durability. The problem of sealing the gas causes the air seal to maintain a better buffer condition.

In order to achieve the above object, the non-linear check valve structure of the present invention is constructed by placing two narrow plastic inner membranes in an air seal body composed of two wide plastic outer membranes, including: on the inner membrane The heat seal forms a plurality of arc lines, which are respectively located on both sides of the inner membrane, and include a plurality of left arcs on one side of the inner membrane and a plurality of right arcs on the other side, and the left and right arcs are left and right Arranged in an asymmetrical manner, a gap is formed between the left end of the left arc and the bottom end of the right arc, and the notch is adjacent to an arc concave surface of the other side arc, and is arranged in a plurality of groups from top to bottom in a left-right matching manner to form a non-linear gas stop. Valve structure.

By the above, when the sealing body is inflated via the air insufflation valve structure, air enters the air inlet from one of the tops of the inner membrane and then flows along an arc of one of the left and right arcs to a lower arc, and Blocked by the arc concave surface and turned into the gap, the gap is guided by the arc above the other side arc to the arc below the arc, and flows into the gap, forming a right arc, a notch, a left arc, a gap, etc., according to the right Or, in a left-right manner, turn over to an air outlet of the bottom of the inner membrane to enter the sealing body.

According to this, when the air in the sealing body is recirculated through the air inlet path of the air valve, the left and right arcs can be subjected to layer blocking and drainage, and the return air is successively shunted, so that the return air rarely flows to the air inlet. The purpose of resisting the reflow is achieved, but the problem that the inflation is difficult or not smooth due to the emphasis on blocking the backflow of the air is not caused, so that the air sealing body is kept in a better buffer state.

Further embodiments of the present invention are further described below: a heat-resistant material is pre-coated at a predetermined air inlet port on the inner surface of any of the inner membranes at the top of the inner membrane, and the inner membrane is placed in the outer membrane and heat-sealed together. After the wire is sealed, the inner surface of the inner film at the heat-resistant material is not heat-sealed, and the air inlet of the sealing body is formed. When inflating, the air flows through the air inlet and the right and left arcs until the bottom of the inner film The gas port enters the sealing body.

A drain channel for withdrawing return air is preset between the upper and lower arc lines, and the lower end of the arc is a natural blockage when the air is recirculated, so that the backflow air is blocked by the lower end of the arc when the return air is returned, and the drain channel is taken out by the blocked air. Introducing a confined space, such that the gas stored in the sealing body is not easily returned to the original gas inlet due to the blocking and drainage of the left and right arc layers, so that the sealing body retains gas for a long time. Ensuring the buffering capacity of the sealing body; the heat sealing length of the drainage channel extends to a boundary line of the sealing space, and the sealing space is spaced apart from the plurality of independent sealing chambers, so that the gas extracted by the drainage channel can mutually Do not stack, do not interfere with each other.

The inner film and the single outer film of the sealing body pre-heat seal the arc to form a tight connection between the gas stop valve and the outer film. After the sealing body is inflated, no internal air expands to generate an internal pressure, and the gas stop valve is pressed to form a lock. Improve the air lock effect.

Alternatively, the gas stop valve is separately disposed between the outer membranes. When the sealing body is inflated, the inside of the sealing body is increased due to the air expansion pressure, so that the gas sealing valve is pressed on both sides to form a lock to improve the air lock. Gas effect.

An air travel route from the air inlet to the air outlet is formed between the left arc line and the right arc line, and the air travel route is mixed with the traditional linear mode in a nonlinear manner, and is matched with the upper section as needed, or Match.

Forming at least one air chamber between the outer membranes, each of the air chambers is provided with at least a single air inlet, and the air inlets formed by the left and right arcs connecting the air inlets and the heat resistant material are heated. The sealing line is closely butted to form an air travel path sealed to the left and right to prevent the air returning from the air from leaking from the air inlet and the left and right arcs through an air passage of the sealing body.

The number of combinations of the arcs and the bottoms arranged, and the distance between the arcs and the notches, may be determined according to the number and spacing.

The gas stop valve is used as a separate piece, or is disposed in a continuous manner on the continuous air column type air sealing body, and is ensured to be continuously set when an inflation passage of the continuous air column type air sealing body is inflated. The air inlet of the air valve can be automatically opened, and the heat-resistant material preset on the inner film is extended to the air passage, and a heat sealing node is disposed on the inner film and the outer film on the heat-resistant material. The inner surface of the inner membrane is coated with a heat-resistant material, so that the inner surface of the inner membrane is not adhered when heat-sealed, and the inner membrane and the adjacent outer membrane are heat-sealed, and then when the inflation passage is inflated The film will expand outwardly, and the action causes the opposite outer film to be pulled outward together with the inner film, which naturally forms the inflation channel to automatically pull the inner film and the air inlet.

The air passage of the continuous air column type air sealing body does not have a heat sealing node, and the inner and outer membranes of the gas column inlet of the air inlet are simultaneously heat sealed to form a heat sealing block, and the air is sealed. When the road is inflated, the heat sealing block does not inflate and expand, and the air passage of the heat-free sealing block expands due to inflation, so that the air inlet port is pressed by the two heat sealing blocks, so that the air inlet port is automatically opened.

The invention further includes that the left and right arcs are arranged in an asymmetrical manner, and the arc and the lower phase are connected up to the bottom of the inner membrane to form a closed air travel route.

The air outlet 24 enters the inside of the sealing body 1. Wherein, an air travel route 5 from the air inlet 23 to the air outlet 24 is formed between the left and right arcs 3, 4.

The number of combinations of the left and right arcs 3, 4 up and down, and the distance between the left and right arcs 3, 4 and the notch 51 can be determined according to the number and spacing.

A draining passage 52 for withdrawing return air is preset between the upper arcs 31 and 41 and the lower arcs 32 and 42. The arcs 32 and 42 below the lower ends of the left and right arcs 3 and 4 are used for natural blocking when the air is recirculated. It is designed such that the returning air is blocked by the arcs 32, 42 below the lower ends of the left and right arcs 3, 4, and the drain 52 is taken out of the blocked air and introduced into a sealed space 200.

In this way, because the left and right arcs 3 and 4 layers are blocked and drained, the gas stored in the sealing body 1 is not easily returned to the original gas inlet port 23, and the gas is sealed for a long time. The buffering capacity of the sealing body 1.

In a specific implementation, the sealing body 1 has at least one air chamber 10 located between the outer membranes 11, 12, and the inner membranes 21, 22 extend into the air chamber 10, respectively. And 22 are connected to each other, and a valve chamber 20 is formed between the inner membranes 21 and 22, and the top end and the bottom end of the inner membranes 21 and 22 respectively form an air inlet 23 connecting the outside and the valve chamber 20, and The valve chamber 20 and the air outlet 24 inside the air chamber 10 are connected.

The left and right arcs 3 and 4 are alternately arranged in the valve chamber 20 between the air inlet 23 and the air outlet 24, and are respectively connected between the inner membranes 21 and 22, the left and right arcs. 3, 4 lower end arcs 32, 42 respectively extend to the central axis 202 of one of the air inlet 23 and the air outlet 24, and the left side of the left and right arcs 3, 4 are respectively formed toward the air inlet. 23, the arc concave surfaces 33, 43 which are inclined toward the air outlet 24, and the other arc convex surfaces 34, 44 which are inclined toward the air inlet 24 and inclined toward the air inlet 23.

The air travel path 5 forms a meandering pattern between the air inlet 23, the arc concave surfaces 33, 43 and the air outlet 24, and the air that is directed from the air inlet 23 to the air outlet 24 is along the concave surface of the arc. 33, 43 enter the air outlet 24 in a winding manner.

The confined space 200 may be plural, respectively formed between the arcuate convex surfaces 34, 44 and the inner wall of the valve chamber 20, and the top ends of the left and right arcs 3, 4 adjacent to the air inlet 23 respectively extend to the air inlet. The inner wall of the peripheral valve chamber 20 is blocked, and the top end of the sealed space 200 is blocked from communicating with the air inlet port 23.

The drainage channels 52 are respectively formed between the upper and lower adjacent arcuate surfaces 34, 44 and the left and right arcs 3, 4, and communicate with the air travel route 5 and the confined space 200, and are guided from the air outlet 24 Part of the air flowing in the direction of the air inlet 23 enters the sealed space 200 along the arcuate surfaces 34, 44.

In another specific implementation, the sealing body 1 can be a cushioning air bag; or the sealing body 1a can also be a packaging air bag (as shown in FIG. 10).

The top ends of the arcs 31 and 41 on the left and right arcs 3 and 4 extend toward the sealed space 200 to form a flow guiding portion 311 and 411 corresponding to the upper adjacent arc convex surfaces 34 and 44. .

The lower arcs 32, 42 at the bottom ends of the left and right arcs 3, 4 on the valve chamber 20 side correspond to the arcuate concave surfaces 33, 43 of the left and right arcs 3, 4 on the other side of the valve chamber 20.

The arcuate concave surfaces 33, 43 of the left and right arcs 3, 4 on the side of the valve chamber 20 are interdigitated with the arcuate concave surfaces 33, 43 of the left and right arcs 3, 4 on the other side of the valve chamber 20.

The flow path 52 on the side of the valve chamber 20 corresponds to the arc concave surfaces 33, 43 on the other side of the valve chamber 20.

Further, other embodiments of the present invention are further described. A heat-resistant material 6 is pre-coated at a predetermined air inlet port on the inner surface of any of the inner films 21 and 22 at the top of the inner film 21, 22. The heat-resistant material 6 may be a heat-resistant ink. After the inner films 21, 22 are placed in the outer film 11, 12 and the horizontal heat seal line 7 is heat sealed together, the inner faces of the inner films 21, 22 at the heat resistant material 6 are not heat sealed. The air inlet port 23 of the sealing body 1 is formed, and when inflated, the air flows through the air inlet port 23 along the left and right arcs 3, 4 until the air outlet port 24 at the bottom of the inner film 21, 22 enters the air chamber 10 of the sealing body 1.

Each of the air chambers 10 is provided with at least a single air inlet port 23, and the left and right arcs 3, 4 connected to the air inlet port 23 are closely abutted with the heat seal line formed by the heat resistant material 6 to make the air travel route 5 The left and right airtight seals prevent the air that flows back in the future from leaking from the air inlet 23, the air travel path 5, and the left and right arcs 3, 4 through the air passage 13 of the sealing body 1 to leak out the sealing body 1.

The inner membranes 21 and 22 and the single outer membranes 11 and 12 of the sealing body 1 may heat seal the left and right arcs 3 and 4 in advance to form the gas stop valve and the outer membranes 11 and 12 in close contact with each other. The sealing body 1 After the inflation, no internal air expands to generate an internal pressure, and the anti-gas valve is pressed to form a lock to improve the air-locking effect; or the air stop valve is separately disposed between the outer membranes 11 and 12, when the sealing body 1 is inflated, The inside of the sealing body 1 is increased in air expansion pressure, so that the air-closing valve is pressed on both sides to form a lock, thereby improving the air-locking effect.

When implemented, the outer membranes 11 and 12 of the sealing body 1 are combined with a gas inner membrane 21, 22 to form a plurality of independent gas chambers 10, wherein each gas chamber is provided with at least one gas inlet port 23, as shown in FIG. One air chamber 10 is provided with an air inlet port 23, and two or more air inlet ports 23 may be provided in one air chamber 10, and the non-linear air stop structure of the present invention is disposed thereafter.

With the above configuration, when air is charged into the valve chamber 20 via the air inlet port 23, the air flows along the arcuate surface 33 and the lower arc line 32 of the upper arc line 31 of the left arc 3 of the layer, and the air is circumscribed by the concave surface 33. Then, the arc concave surface 43 of the right arc 4 is guided to quickly turn into the notch 51, and then flows along the upper arc 31, the arc concave surface 33 and the lower arc line 32 along the left arc 3 of the other layer; therefore, the air can be passed through The arc concave surfaces 33 and 43 are rotated in the same direction, and the right-handed and right-handed ends are formed, and the gap 51 is entered, and the flow form of the left-handed, left-handed, and entering the notch 51 is formed.

It is worth mentioning that, because the left and right arcs 3 and 4 are streamlined and the wind resistance is low, the air is easy to slide, and will turn left and right, causing the air to travel in the route 5 to rotate and accelerate the inflation. And the gas is continuously oscillated by left and right, right and left, corresponding to a semicircle rotation at the end of the arcs 32 and 42 below the left and right arcs 3 and 4. Since the left and right arcs 3 and 4 have a low drag coefficient, The upper semi-circular rotary displacement causes the air to rotate automatically to increase the flow rate, which helps the air to accelerate into the sealing body 1 and can pass quickly.

In this way, the flow is downward in the non-linear direction by the left shift and the right shift, and because the arc concave surfaces 33 and 43 have the air streamline type, the wind resistance is extremely low, and the air enters the left and right arcs 3 and 4 from the air inlet 23 . The oscillating curved track forms a rotating wind sway, which is not only blocked by the left and right arcs 3, 4, but is accelerated by the displacement oscillating motion, and has the effect that the lift gas quickly passes through the air travel route 5.

When the sealing body 1 is inflated, when the air in the air chamber 10 flows back and the return air flows back through the original air inlet path, first, the arcs 32 and 42 below the left and right arcs 3 and 4 are blocked, so that About half of the air flows along the arcuate surfaces 34, 44 and is diverted into the confined space 200 via the drain 52; the other half of the air flows back through the notch 51 to the air travel path 5, ie, the left and right arcs of the layer arrangement The lower arcs 32, 42 of 3, 4 are blocked from the arcuate faces 34, 44, and finally the air flowing back to the air inlet 23 is seldom, that is, the object of the present invention is achieved.

Accordingly, when the air in the sealing body 1 recirculates through the air inlet path of the air valve, the left and right arcs 3 and 4 can be subjected to layer blocking and drainage, and the return air is sequentially divided, so that the return air rarely flows to At the air inlet 23, the purpose of blocking the reflow is achieved, but the problem that the inflation is difficult or not smooth due to the emphasis on blocking the air backflow is not caused, so that the air sealing body 1 is kept in a better buffer state.

In practice, the heat seal length of the flow guiding portions 311, 411 at the drain passage 52 may also extend to a boundary line 203 of the sealed space 200 (as shown in FIGS. 5 and 6), and the sealed space 200 is spaced apart. The plurality of independent sealed chambers 201 are connected to each other, and the adjacent flow guiding portions 311 and 411 can be connected to each other, so that the gases drawn from the draining passages 52 can be stacked without mutual interference.

In implementation, the air travel route 5 can be mixed with the traditional linear mode in a non-linear manner (as shown in FIG. 7 and FIG. 8), and can be matched with the upper segment or the upper and lower sides as needed; wherein, the upper segment of FIG. 7 is a conventional In the linear mode, the lower segment is a nonlinear mode; the upper segment of Figure 8 is a nonlinear mode, and the lower segment is a traditional linear mode.

In practice, the left and right arcs 3a, 4a are arranged in an asymmetrical manner (as shown in FIG. 9), and the upper and lower ends of the arcs 3a, 4a are connected until the bottom of the inner membranes 21, 22, forming a closed Air travel route 5a.

In addition, the gas stop valve is used as a separate piece, or is disposed in a continuous manner on the continuous air column type air sealing body 1 (as shown in FIGS. 1 and 5), in the continuous gas column type. When the inflation passage 13 of the air seal body 1 is inflated, the air inlet port 23 of the air check valve that is continuously disposed can be automatically opened, and the heat-resistant material 6 preset on the inner film 21, 22 can be extended to the air passage 13 . And pre-applying a heat-sealing node 14 on the heat-resistant material 6 on the inner film 21, 22 and the outer film 11, 12, because the inner surface of the inner film 21, 22 is coated with a heat-resistant material 6, so when heat-sealed The inner surfaces of the inner membranes 21, 22 are not followed, and the inner membranes 21, 22 and the adjacent outer membranes 11, 12 are followed by heat sealing; thus, the outer membrane 11, when the inflation passage 13 is inflated, 12 will expand outward, this action causes the opposite outer membranes 11, 12 and the inner membranes 21, 22 to be pulled outward together, which naturally forms the inflation passage 13 to automatically pull the inner membrane 21 apart. 22 and the action of the air inlet 23.

Moreover, another preferred implementation side of the automatic opening air inlet 23 is to cancel the extension of the preset heat-resistant material 6 of 21, 22, and directly heat-sea the inner membrane 21, 22 on both sides of the air inlet 23 of the air column 13 . Forming a stack of block heat sealing blocks 8 (shown in FIG. 7) with the outer membranes 11, 12, in order to cause the inflating block 13 to inflate, and the heat-free sealing block 8 will contract due to inflation and heat. The sealing block 8 is pressed toward the air inlet 23, causing the air inlet 23 to automatically open.

The non-linear air valve structure according to claim 1, wherein the inner film and the single outer film of the sealing body pre-heat seal the arc to form the gas stop valve and the outer film, and the sealing body is inflated. After the internal air is not expanded, the internal pressure is generated, and the air lock valve is pressed to form a lock to improve the air lock effect. The non-linear air valve structure according to claim 1, wherein the gas stop valve is separately disposed between the outer membranes, and when the sealing body is inflated, the inside of the sealing body is increased due to air expansion pressure, so that The gas stop valve is pressed on both sides to form a lock to improve the air lock effect. The non-linear air valve structure according to claim 1, wherein the left arc line and the right arc line form an air travel route from the air inlet port to the air outlet port, and the air travel route is in a nonlinear manner. Mix with traditional linear methods, match the upper section as needed, or mix up and down. The non-linear check valve structure according to claim 1, wherein the inside of the sealing body forms at least one air chamber between the outer membranes, and each of the air chambers has at least a single air inlet port, and the connection is made The left and right arcs of the air port are closely abutted with the air inlet heat sealing line formed by the heat resistant material, so as to prevent the air returning from the air from leaking from the air inlet and the left and right arcs. The sealing body. The non-linear air valve structure according to claim 1, wherein the number of combinations of the arcs and the bottoms, and the distance between the arcs and the notches can be determined according to requirements. The non-linear air valve structure according to claim 1, wherein the gas stop valve is used as a separate piece or is continuously disposed on the continuous air column type air sealing body, and the continuous gas column is used. The air inlet of the air sealing body is inflated to ensure that the air inlet of the air valve can be automatically opened, and the heat resistant material preset in the inner film extends to the air passage, and a heat sealing node is pre-applied. In the inner film and the outer film on the heat-resistant material, since the inner surface of the inner film is coated with a heat-resistant material, the inner surface of the inner film is not adhered during heat sealing, and the inner film is in contact with the inner film The outer membrane is then heat-sealed, and the outer membrane is deployed outward when the inflation passage is inflated. This action causes the opposite outer membrane to be pulled outward together with the inner membrane, thereby naturally forming the inflation passage. The inflation automatically pulls open the inner membrane and the air inlet. The non-linear air valve structure according to claim 10 of the patent application scope is further included in the continuous air column type air sealing body, and the air passage is not provided with a heat sealing node, and is replaced by an air inlet port of the air column. The inner membrane and the second outer membrane are simultaneously heat-sealed to form a heat-sealed block. When the inflation channel is inflated, the heat-sealed block does not inflate and expand, and the air-filled channel without the heat-sealed block expands and contracts due to inflation, resulting in two The heat sealing block squeezes the air inlet to automatically open the air inlet. The non-linear air valve structure according to claim 1, further comprising the left and right arcs arranged in an asymmetric manner, wherein the arc and the bottom are connected to the bottom of the inner membrane to form a closed type. Air travel route.
