In an embodiment, referring to fig. 1, fig. 2, fig. 4 and fig. 5, a sealing structure 100 includes: the edge banding base 110, the first clamping member 120 and the second clamping member 130. The edge sealing base 110 is provided with a first engaging groove 111. The groove wall of the first engaging groove 111 includes a first abutting wall 112 and a second abutting wall 113 disposed opposite to each other. The first clamping member 120 and the second clamping member 130 are used for clamping the sealing edge 210, when the first clamping member 120 and the second clamping member 130 are inserted into the first clamping groove 111, the first clamping member 120 is in interference fit with the second clamping member 130, the first clamping member 120 is detachably connected with the first interference wall 112, and the second clamping member 130 is detachably connected with the second interference wall 113.

In the sealing structure 100, the sealing edge 210 is clamped between the first clamping member 120 and the second clamping member 130 during the sealing process; then the clamped first clamping piece 120 and the second clamping piece 130 are inserted into the first clamping groove 111 together; and the first clamping member 120 is coupled to the first interference wall 112 and the second clamping member 130 is coupled to the second interference wall 113. Because the first clamping member 120 and the second clamping member 130 are inserted into the first clamping groove 111 together and mutually abutted, the sealing edge 210 is tightly fixed under the action of the first clamping member 120 and the second clamping member 130, even if the bag body 200 expands under the action of a heavy object, the first clamping member 120 and the second clamping member 130 can also correspond to the first abutting wall 112 and the second abutting wall 113 and tightly clamp the sealing edge 210, so that the sealing edge 210 cannot be pulled out, thereby effectively improving the edge sealing effect of the bag body 200 and greatly improving the service quality of the storage bag. Meanwhile, the edge sealing operation difficulty of the bag body 200 is effectively reduced, and the edge sealing efficiency is improved. When the storage bag is used up, the first clamping member 120 and the second clamping member 130 are correspondingly removed from the first abutting wall 112 and the second abutting wall 113, respectively, so that the sealing edge 210 is separated from between the first clamping member 120 and the second clamping member 130. Because the sealing edge 210 is only clamped and not damaged in the sealing process, the separated bag body 200 does not affect secondary utilization, and thus sustainable development of limited resources is greatly promoted. Likewise, the removed edge banding structure 100 can be reused many times.

It should be noted that, when the first clamping member 120 and the second clamping member 130 are inserted into the first slot 111, the interference fit between the first clamping member 120 and the second clamping member 130 should be understood as: when the first clamping member 120 and the second clamping member 130 are inserted into the first slot 111, the first clamping member 120 is abutted by the first abutting wall 112, and the second clamping member 130 is abutted by the second abutting wall 113, so that the first clamping member 120 and the second clamping member are close to each other and extruded.

The first protrusion is obliquely disposed on the first interference wall 112, and a free end of the first protrusion is inclined toward the bottom of the first catching groove 111. Therefore, the first fastening portion 1121 of the present embodiment is inclined, and one end of the first fastening portion 1121 is inclined toward the bottom of the first locking slot 111, so that when the third fastening portion 121 is fastened to the first fastening portion 1121, the acting force of the first fastening portion 1121 on the third fastening portion 121 is directed toward the bottom of the first locking slot 111, so that the first clamping member 120 is stabilized in the first locking slot 111, the bag body 200 is prevented from slipping out of the first locking slot 111 under the action of a heavy object, and the sealing edge 210 is ensured to be more stabilized in the first locking slot 111.

It should be noted that the free end of the first projection is understood to be: the free end of the first protrusion is the end of the first protrusion away from the first interference wall 112. Meanwhile, the bottom of the first card slot 111 is understood as: the bottom of the first card slot 111 is a portion opposite to the notch of the first card slot 111.

Specifically, the third locking portion 121 of the present embodiment is also a protrusion, and the protrusion is also disposed obliquely on the first clamping member 120, and meanwhile, the free end of the protrusion is disposed toward the notch of the first locking groove 111.

Thus, the edge sealing structure 100 is designed to be a cylindrical structure, which is beneficial to enhancing the fixing force of the edge sealing base 110 to the first clamping piece 120 and the second clamping piece 130, and ensures that the edge sealing effect of the bag body 200 is more stable. At this time, the free end of the first protrusion is inclined toward the axis of the edge sealing base 110, and the free end of the third protrusion is inclined away from the axis of the edge sealing base 110.

In an embodiment, referring to fig. 2 and fig. 3, the first fastening portions 1121 and the third fastening portions 121 are both multiple, the multiple first fastening portions 1121 are disposed at intervals on the first abutting wall 112, and the multiple first fastening portions 1121 are disposed at intervals on the first clamping member 120, so that the combining force between the first clamping member 120 and the first abutting wall 112 is favorably enhanced.

In one embodiment, referring to fig. 2, the second locking portion 1131 is a second protrusion. The second protrusion is obliquely disposed on the second interference wall 113, and a free end of the second protrusion is inclined toward the bottom of the first card slot 111. Thus, when the fourth fastening portion 131 is fastened to the second fastening portion 1131, the acting force of the second fastening portion 1131 on the fourth fastening portion 131 is toward the bottom of the first engaging groove 111, so that the second clamping member 130 is stabilized in the first engaging groove 111, thereby preventing the bag body 200 from slipping off from the first engaging groove 111 under the action of a heavy object, and ensuring that the sealing edge 210 is more stabilized in the first engaging groove 111.

It should be noted that the free end of the second projection is understood to be: the free end of the second protrusion is the end of the second protrusion away from the second interference wall 113. Meanwhile, the bottom of the first card slot 111 is understood as: the bottom of the first card slot 111 is a portion opposite to the notch of the first card slot 111.

Specifically, the fourth locking portion 131 of the present embodiment is also a protruding structure, and the protruding structure is also disposed obliquely on the second clamping member 130, and meanwhile, a free end of the protruding structure is disposed toward the notch of the first locking groove 111.

Therefore, in the edge sealing process, the sealing edge 210 is inserted into the bayonet 114; the first clamping member 120 and the second clamping member 130 are inserted into the first slot 111, respectively.

Further, referring to fig. 4, a stop portion 220 is disposed on the sealing edge 210, the stop portion 220 is located in the bayonet 114, and the stop portion 220 is respectively in interference fit with the first clamping member 120 and the second clamping member 130. When a heavy object is loaded in the bag body 200, the sealing edge 210 tends to be separated from the first clamping groove 111 due to the stress, and the stopping portion 220 is disposed on the sealing edge 210, and the stopping portion 220 is in interference fit with the first clamping member 120 and the second clamping member 130, so that under the action of the first clamping member 120 and the second clamping member 130, an acting force is applied to the sealing edge 210 toward the inside of the first clamping groove 111 to prevent the sealing edge 210 from separating from the sealing structure 100.

Specifically, the stopper 220 is a sealing strip 230, and in actual use, the stopper 220 is a male and female plastic sealing strip 230, and both sides of the sealing edge 210 are hermetically connected through the male and female sealing strips 230.

In one embodiment, referring to fig. 2, the first abutting wall 112 and the second abutting wall 113 are disposed at an included angle, and an angle θ formed by the first abutting wall 112 and the second abutting wall 113 is a minor angle. In this way, the first clamping member 120 and the second clamping member 130 are stably combined in the first clamping groove 111.

Note that the inferior angle is a convex angle, which means an angle greater than 0 ° and less than 180 °.

In one embodiment, referring to fig. 2, a plurality of third protrusions 115 are spaced apart from each other on the edge sealing base 110, and the third protrusions 115 increase the friction force on the edge sealing base 110, so that the edge sealing base is convenient for a user to use. Meanwhile, the third convex peak 115 is arranged on the edge sealing base 110, so that a foundation is provided for subsequent buckling connection. Of course, the third hump 115 can also be disposed on the first support and the second support.

In one embodiment, referring to fig. 1, 2, 6 and 7, a storage bag includes a bag body 200 and the sealing edge structure 100 of any of the above embodiments. The bag body 200 has at least one set of sealing edges 210. The seal edge 210 is clamped between the first clamping member 120 and the second clamping member 130.

The storage bag adopts the edge sealing structure 100, and in the edge sealing process, the sealing edge 210 is clamped between the first clamping piece 120 and the second clamping piece 130; then the clamped first clamping piece 120 and the second clamping piece 130 are inserted into the first clamping groove 111 together; and the first clamping member 120 is coupled to the first interference wall 112 and the second clamping member 130 is coupled to the second interference wall 113. Because the first clamping member 120 and the second clamping member 130 are inserted into the first clamping groove 111 together and mutually abutted, the sealing edge 210 is tightly fixed under the action of the first clamping member 120 and the second clamping member 130, even if the bag body 200 expands under the action of a heavy object, the first clamping member 120 and the second clamping member 130 can also correspond to the first abutting wall 112 and the second abutting wall 113 and tightly clamp the sealing edge 210, so that the sealing edge 210 cannot be pulled out, thereby effectively improving the edge sealing effect of the bag body 200 and greatly improving the service quality of the storage bag. Meanwhile, the edge sealing operation difficulty of the bag body 200 is effectively reduced, and the edge sealing efficiency is improved. When the storage bag is used up, the first clamping member 120 and the second clamping member 130 are correspondingly removed from the first abutting wall 112 and the second abutting wall 113, respectively, so that the sealing edge 210 is separated from between the first clamping member 120 and the second clamping member 130. Because the sealing edge 210 is only clamped and not damaged in the sealing process, the separated bag body 200 does not affect secondary utilization, and thus sustainable development of limited resources is greatly promoted. Likewise, the removed edge banding structure 100 can be reused many times.

It should be noted that the sealing edge requires two sealing edges 210 to seal and make the bag body 200 have a bag-like structure, and therefore, the group of sealing edges 210 in this embodiment refers to two sealing edges 210. Meanwhile, the number of the sealing operations required to be performed on the bag body 200 may be one side, two sides, three sides, or more.

Further, referring to fig. 7 and 11, the storage bag further includes a handle 300, a first fastener 400, and a second fastener 500 connected to the first fastener 400. One side of the bag body 200 is fastened to the first fastener 400. The handle 300 is snapped onto the first snap-fit member 400. Therefore, in the assembly process of the storage bag, after the bag body 200 is sealed by the sealing structure 100, the first fastener 400 is fastened to the bag body 200; the handle 300 is then fastened to the second fastener 500, so that the handle 300 is stably connected to the bag body 200, and the storage bag is assembled, thereby improving the convenience of use of the storage bag.

Specifically, the handle 300 of the present embodiment adopts the edge sealing structure 100, that is, in the assembling process, one of the edge sealing structures 100 is used as the handle 300 and is fastened on the second fastener 500, so that the types of the parts on the storage bag are reduced, the structural types tend to be uniform, and the need of preparing various different types of parts in the assembly process of the storage bag is avoided.

Further, referring to fig. 8, 9 and 10, the end of the second locking member 500 is provided with a socket 510. A second locking groove 550 communicated with the socket 510 is arranged in the second locking element 500, a slit 520 communicated with the socket 510 is arranged on one side of the second locking element 500, and a locking ring 530 is sleeved on the second locking element 500. The handle 300 is provided with a first peak 310. When the handle 300 is inserted through the insertion opening 510 and extends into the second engagement groove 550, the locking ring 530 is inserted into the slit 520, and the first protrusion 310 is locked in the second engagement groove 550. Therefore, during the assembly process of the handle 300, the locking ring 530 is moved, so that the slit 520 on the second fastener 500 is in the unlocked state, i.e., the insertion opening 510 on the second fastener 500 can be enlarged; inserting one end of the handle 300 into the insertion opening 510 and extending into the second locking groove 550, so that the first convex peak 310 is located in the second locking groove 550; next, the locking ring 530 is moved to make the locking ring 530 fit on the position of the slit 520, so that the insertion opening 510 on the second fastener 500 cannot be expanded, that is, the slit 520 on the second fastener 500 is in a locked state, and at this time, the first hump 310 in the second slot 550 cannot be pulled out, so that the first hump 310 is caught in the second slot 550, thereby completing the fastening operation of the handle 300. Also, the other end of the handle 300 completes the snap connection through the same operation.

Optionally, the connection manner of the first fastener 400 and the second fastener 500 is a bolt connection, a thread connection, a snap connection, an adhesive connection, an integral molding manner, and the like. Similarly, the fastening manner of the first fastener 400 on the bag body 200 may adopt the above sealing edge structure 100 manner or a snap-fastener structure.

Optionally, the lock ring 530 of this embodiment is sleeved at the position of the slit 520 to lock the first convex peak 310 in the second slot 550: the locking ring 530 is an open ring, and when the locking ring 530 is rotated, the open end of the open ring is staggered with the slit 520, that is, the slit 520 cannot be expanded under the constraint of the locking ring 530; or, the locking ring 530 is also an open ring, and the locking ring 530 is provided with a locking bolt, when the locking ring 530 is sleeved at the position of the slit 520, the locking bolt locks the size of the ring of the locking ring 530, so that the slit 520 cannot be expanded; alternatively, the locking ring 530 is a closed loop structure, the locking ring 530 can slide up and down on the second locking member 500, when the locking ring 530 moves up, the closed loop structure is tightly sleeved on the position of the slit 520, of course, when the locking ring 530 is sleeved on the position of the slit 520, a convex part is arranged on the second locking member 500, and the locking ring 530 is prevented from automatically moving down and sliding away from the position of the slit 520.

Specifically, referring to fig. 9, the locking ring 530 is a split ring, and when the open end of the split ring is opposite to the slit 520, the first convex peak 310 can be inserted into or separated from the second locking groove 550; when the open end of the split ring is offset from the slit 520, the first hump 310 is locked in the second locking groove 550.

In an embodiment, referring to fig. 12, 13 and 14, the second locking member 500 includes a fifth locking portion 560 and a sixth locking portion 570 movably connected to each other, the fifth locking portion 560 and the sixth locking portion 570 enclose a first locking cavity 580 and a second locking cavity 590 with opposite space changes, the first locking cavity 580 includes a first component cavity 581 and a second component cavity 582 connected to each other, the first component cavity 581 is located between the second component cavity 582 and the second locking cavity 590, the handle 300 is provided with a first hump 310, the first locking member 400 is provided with a second hump 410, the first hump 310 and the second hump 410 are respectively inserted into the first component cavity 581 and the second locking cavity 590, and when the first hump 310 moves into and is locked in the second component cavity 582, the second locking cavity 590 is shrunk and can lock the second hump 410. Therefore, when the fifth fastening part 560 and the sixth fastening part 570 move relatively, the sizes of the first clamping cavity 580 and the second clamping cavity 590 change oppositely, that is, when the size of the first clamping cavity 580 increases, the size of the second clamping cavity 590 decreases; when the space of the first clamping cavity 580 becomes smaller, the space of the second clamping cavity 590 becomes larger. Thus, during the assembly process, the first protrusion 310 and the second protrusion 410 are inserted into the first split-cavity 581 and the second clamping cavity 590, respectively, and at this time, the space of the second clamping cavity 590 is larger than the size of the second protrusion 410. When the first hump 310 is transferred from the first split cavity 581 to the second split cavity 582, the first hump 310 catches in the second split cavity 582 and the space of the second clamping cavity 590 is reduced so that the cavity walls of the second clamping cavity 590 can catch the second hump 410. This means that the space of the second body cavity 582 is smaller than the first hump 310, so that when the first hump 310 is snapped into the second body cavity 582, the second body cavity 582 is expanded, and since the space of the first snap-fit cavity 580 is opposite to that of the second snap-fit cavity 590, the second snap-fit cavity 590 is gradually reduced and the second hump 410 is snapped, and at the same time, the larger the second body cavity 582 is expanded, the smaller the space of the second snap-fit cavity 590 is, and the tighter the second hump 410 is snapped in. Thus, the handle 300 is stably and conveniently connected to the bag body 200 through the second fastener 500.

It should be noted that the structure of the first clamping cavity 580 and the second clamping cavity 590 in this embodiment can be similarly applied to the connection between the first clamping part 400 and the second clamping part 500, that is, the connection structure also includes a fifth clamping part 560 and a sixth clamping part 570 movably connected, the fifth clamping part 560 and the sixth clamping part 570 enclose a first clamping cavity 580 and a second clamping cavity 590 with opposite space size changes, the first clamping cavity 580 includes a first split cavity 581 and a second split cavity 582 communicated with each other, the first split cavity 581 is located between the second split cavity 582 and the second clamping cavity 590, the second clamping part 500 is provided with a fourth hump 540, the first clamping part 400 is provided with the second hump 410, the fourth hump 540 and the second hump 410 are respectively inserted into the first split cavity 581 and the second clamping cavity 590, when the fourth hump 540 moves into the second split cavity 582 and is clamped, the second clamping cavity 590 is reduced, and can catch the second hump 410.

Optionally, the fifth latch 560 and the sixth latch 570 of the present embodiment are movably connected in a rotating manner or a sliding manner. When the fifth fastening portion 560 is slidably connected to the sixth fastening portion 570, the fifth fastening portion 560 and the sixth fastening portion 570 are S-shaped.

Further, referring to fig. 13, the fifth fastening portion 560 includes a first snap ring 561, a first connecting shaft 562, and a second snap ring 563 that are sequentially connected, an inner annular surface of the first snap ring 561 and an inner annular surface of the second snap ring 563 face to the same side, the fifth fastening portion 560 includes a third snap ring 571, a second connecting shaft 572, and a fourth snap ring 573 that are sequentially connected, an inner annular surface of the third snap ring 571 and an inner annular surface of the fourth snap ring 573 face to the same side, the first connecting shaft 562 is rotatably connected to the second connecting shaft 572, the first snap ring 561 and the third snap ring define a first fastening cavity 580, and the second snap ring 563 and the fourth snap ring 573 define a second fastening cavity 590. Therefore, the fifth locking portion 560 and the sixth locking portion 570 of the present embodiment are both "3" or substantially "3".

Specifically, referring to fig. 13, the first connecting shaft 562 and the second connecting shaft 572 are respectively provided with a shaft hole 5621, and the fifth locking portion 560 and the sixth locking portion 570 are rotatably connected through the shaft holes 5621.

In one embodiment, referring to fig. 15, the bag body 200 has sealing strips 230 on both sides, and the sealing strips 230 are sealed and engaged. In this way, the airtight performance inside the bag body 200 is ensured.

It should be noted that the sealing strip 230 may adopt a sealing structure on a zipper self-sealing bag; the sealing structure on the bone blowing self-sealing bag can also be adopted. When the sealing strip 230 is a sealing structure on the bone blowing self-sealing bag, the convex ribs are clamped in the concave ribs to realize sealing fit.

In one embodiment, referring to fig. 15, the bag body 200 is provided with a cut line 250. The storage bags on the market are fixed and formed in size, and the size and the use are single; and needs to be produced by corresponding equipment. The size of the containing bag can be freely cut according to the cutting line 250, and the containing bag is diversified in purpose and does not need to correspond to production equipment. Meanwhile, the storage bag in the market is a shaping bag. The storage bag is a deformable bag, and a large size is changed into a small size according to the cutting line 250 and the edge sealing structure 100, so that the storage bag is convenient to reuse.

In one embodiment, referring to fig. 1, fig. 2, fig. 6, fig. 7 and fig. 16, a storage apparatus includes a pump structure 600 and a storage bag in any of the above embodiments. The bag body 200 is provided with an air port 240 communicating with the pump structure 600. The pump structure 600 is used to evacuate and/or pressurize the bag body 200.

The above storage apparatus, which adopts the above edge sealing structure 100, clamps the edge sealing edge 210 between the first clamping member 120 and the second clamping member 130 during the edge sealing process; then the clamped first clamping piece 120 and the second clamping piece 130 are inserted into the first clamping groove 111 together; and the first clamping member 120 is coupled to the first interference wall 112 and the second clamping member 130 is coupled to the second interference wall 113. Because the first clamping member 120 and the second clamping member 130 are mutually abutted when being inserted into the first clamping groove 111 together, the sealing edge 210 is tightly fixed under the action of the first clamping member 120 and the second clamping member 130, even if the bag body 200 expands under the action of a heavy object, the first clamping member 120 and the second clamping member 130 can tightly clamp the sealing edge 210 under the action of the first abutting wall 112 and the second abutting wall 113 correspondingly, so that the sealing edge 210 cannot be pulled out, the sealing effect of the bag body 200 is effectively improved, and the use quality of the storage bag is greatly improved. Meanwhile, the edge sealing operation difficulty of the bag body 200 is effectively reduced, and the edge sealing efficiency is improved. When the storage bag is used up, the first clamping member 120 and the second clamping member 130 are respectively removed from the first abutting wall 112 and the second abutting wall 113, so that the sealing edge 210 is separated from the space between the first clamping member 120 and the second clamping member 130. Because the sealing edge 210 is only clamped and not damaged in the sealing process, the separated bag body 200 does not affect secondary utilization, and thus sustainable development of limited resources is greatly promoted. Likewise, the removed edge banding structure 100 can be reused many times.

It should be noted that the communication mode between the air interface 240 and the pump structure 600 can be realized by providing the primary and secondary sealing strips 230 or the internal and external thread structures on the pump structure 600 and the bag body 200, respectively.

In one embodiment, referring to fig. 16, 17, 18 and 19, the pump structure 600 includes: an air bag 610, a first valve core 620 and a second valve core 630. The air bag 610 can elastically stretch and contract, and a first opening 611 and a second opening 612 are arranged on the air bag 610. The first valve core 620 includes a first sealing plate 622 and a first seat 621 provided on the bladder 610. The first base 621 is provided with a first vent 6211 communicating with the first opening 611. The second valve spool 630 includes a second sealing plate 632 and a second seat 631 provided on the air bag 610. The second base 631 is provided with a second air vent 6311 for communicating with the second opening 612 and the air port 240 of the bag body 200, respectively. The expansion of the airbag 610 can trigger the first sealing sheet 622 and the second sealing sheet 632 to correspondingly control the opening and closing of the first vent 6211 and the second vent 6311, and when the airbag 610 is expanded or compressed, the opening and closing state of the first vent 6211 is opposite to the opening and closing state of the second vent 6311.

The pump structure 600 described above, during evacuation or pressurization, mounts the second base 631 on the bag body 200 such that the second vent 6311 communicates with the air port 240; after the connection, the airbag 610 is expanded and contracted. When the airbag 610 is compressed or expanded, the first sealing sheet 622 and the second sealing sheet 632 can be triggered to correspondingly control the opening and closing of the first vent 6211 and the second vent 6311, and the opening and closing states of the first vent 6211 and the second vent 6311 are opposite, so when the airbag 610 is compressed, if the first vent 6211 is in an open state, the second vent 6311 is in a closed state, and at this time, gas is exhausted from the first vent 6211 to the atmosphere; when the airbag 610 is expanded, the first vent 6211 is closed and the second vent 6311 is opened, and at this time, the airbag 610 sucks air from the bag body 200 to evacuate the bag body 200. In contrast, when the airbag 610 is compressed, if the first vent port 6211 is in the closed state, the second vent port 6311 is in the open state, and at this time, gas is discharged from the second vent port 6311 into the bag body 200; when the air bag 610 is expanded, the first vent 6211 is in an open state and the second vent 6311 is in a closed state, and at this time, the air bag 610 sucks air from the outside atmosphere, so that the pressurization operation of the bag body 200 is realized. Because this embodiment adopts flexible mode, evacuates or the pressure boost operation to bag body 200, consequently, the user only needs the one-hand operation to accomplish corresponding operation promptly, has simplified bag body 200 greatly and has evacuated or aerify in-process operation process, promotes the use experience of product and feels. Because the air bag 610 is of an elastic telescopic structure, after the operation is finished, the whole volume of the pump body can be reduced by compressing the air bag 610, the storage space is reduced, and the storage utilization rate of the space is improved.

It should be noted that the elastic expansion of the air bag 610 is understood as: after compression, the balloon 610 will rebound to return to its pre-compressed configuration by virtue of its elastic structural design or elastic material properties. Wherein the elastic structure design can be understood as a spring ring structure, and the elastic material is a rubber material.

It should be further noted that, the expansion and contraction of the airbag 610 can trigger the first sealing piece 622 and the second sealing piece 632 to correspondingly control the opening and closing of the first ventilation opening 6211 and the second ventilation opening 6311, which is understood as follows: the expansion and contraction of the airbag 610 can cause the gas at the first vent 6211 and the second vent 6311 to flow, when the first sealing piece 622 covers the first vent 6211, the flowing gas can cause the pressure difference at two sides of the first sealing piece 622 to be inconsistent, the first sealing piece 622 can be attached to the first vent 6211 or be far away from the first vent 6211, and if the first sealing piece 622 is attached to the first vent 6211, the first vent 6211 is closed; if the first sealing piece 622 is away from the first ventilation opening 6211, the first ventilation opening 6211 is opened. Similarly, the opening and closing principle of the second sealing sheet 632 for the second vent 6311 is similar, and is not described in detail here. Meanwhile, the first sealing piece 622 and the second sealing piece 632 both have a certain elastic deformation function, and a specific material may be a rubber piece or a plastic piece.

In addition, the open and closed state of the first vent 6211 as opposed to the open and closed state of the second vent 6311 when the airbag 610 is expanded or compressed should be understood as follows: when the airbag 610 is expanded or compressed, the first vent 6211 is opened, and the second vent 6311 is closed; when first vent 6211 is closed, second vent 6311 is open.

Optionally, the first base 621 and the second base 631 may be mounted on the airbag 610 in the following manners: the sealing strip 230 is clamped, adhered, screwed, etc. Meanwhile, the second base 631 may be connected to the bag body 200 by using the sealing strip 230 to be engaged or screwed. When the second base 631 adopts a threaded connection, the bag body 200 is provided with a base, the base is provided with an internal thread, and the second base 631 is provided with an external thread. Of course, the base may have external threads and the second base 631 may have internal threads.

Further, referring to fig. 19, 21, 22 and 23, the first valve core 620 further includes a first rotating shaft 623 rotatably connected to the first base 621. Two first seal pieces 622 are provided on the first rotation shaft 623. A first chamber 6212 is disposed in the first base 621, and first vents 6211 communicated with the first chamber 6212 are disposed on two opposite sides of the first base 621. The two first sealing sheets 622 are respectively located at two opposite sides of the first base 621, or the two first sealing sheets 622 are respectively located at two opposite sides of the first chamber 6212, and when one first ventilation opening 6211 is covered with the first sealing sheet 622, the other first ventilation opening 6211 is in an open state. As can be seen, only one first ventilation opening 6211 is covered with the first sealing sheet 622 between the two first ventilation openings 6211. This ensures that only one first vent 6211 is open and closed during evacuation or pressurization, and the other acts as a vent only. Because the two first sealing sheets 622 are respectively located on the two opposite surfaces of the first base 621, or the two first sealing sheets 622 are respectively located on the two opposite side walls in the first chamber 6212, when the air bag 610 is compressed, one first sealing sheet 622 is tightly attached to the first air vent 6211, and the other first sealing sheet 622 is far away from the first air vent 6211, so that two states, namely evacuation and pressurization, can be realized on the first base 621, and a structural basis is provided for realizing the back-and-forth switching of evacuation operation and pressurization operation.

It should be noted that the open state of the first air vent 6211 is understood as follows: the first sealing sheet 622 does not cover the first vent 6211.

Further, referring to fig. 19, 24, 25 and 26, the second valve core 630 further includes a second shaft 633 rotatably connected to the second base 631. Two second sealing pieces 632 are arranged on the second rotating shaft 633. A second chamber 6312 is disposed in the second base 631, and second vents 6311 communicating with the first chamber 6212 are disposed on two opposite sides of the second base 631. Two second sealing plates 632 are respectively located at opposite sides of the second base 631, or two second sealing plates 632 are respectively located at opposite sides of the second chamber 6312. When one of the second air ports 6311 is covered with the second seal fin 632, the other second air port 6311 is opened. Because the two second sealing pieces 632 are respectively located on two opposite surfaces of the second base 631, or the two second sealing pieces 632 are respectively located on two opposite sidewalls in the second chamber 6312, when the airbag 610 is compressed, one second sealing piece 632 is tightly attached to the second vent 6311, and the other second sealing piece 632 is far away from the second vent 6311, so that two states, namely evacuation and pressurization, can be realized on the second base 631, and a structural basis is also provided for realizing the back-and-forth switching of evacuation operation and pressurization operation.

It should be noted that, in the present embodiment, the first rotating shaft 623 and the second rotating shaft 633 can rotate independently, that is, the first rotating shaft 623 and the second rotating shaft 633 can rotate independently, so that the pump-down function and the pressure-increasing function of the pump structure 600 can be switched back and forth. For example, for the case where two first sealing pieces 622 are located on opposite sides of the first base 621 and two second sealing pieces 632 are located on opposite sides of the second base 631: first, by rotating the first rotating shaft 623, the first sealing plate 622 on the side of the first base 621 away from the air bag 610 covers the first vent 6211, and the other first vent 6211 is opened; next, by rotating the second rotating shaft 633 so that the second sealing sheet 632 on the side of the second base 631 close to the air bag 610 covers the second vent 6311, at this time, the air bag 610 is expanded and contracted, and the pump structure 600 can evacuate the bag body 200; secondly, by rotating the first rotating shaft 623, the first sealing sheet 622 on the side of the first base 621 close to the air bag 610 covers the first vent 6211; then, by rotating the second rotating shaft 633, the second seal piece 632 of the second base 631 on the side away from the air bag 610 covers the second vent 6311, and at this time, the air bag 610 expands and contracts, and the pump structure 600 can pressurize the bag body 200. Similarly, the principle is the same for the case where two first sealing plates 622 are located in the first cavity 6212, two second sealing plates 632 are located in the second cavity 6312, two first sealing plates 622 are located on two opposite sides of the first base 621, two second sealing plates 632 are located in the second cavity 6312, two first sealing plates 622 are located in the first cavity 6212, and two second sealing plates 632 are located on two opposite sides of the second base 631, and the description is omitted.
