In an embodiment, referring to fig. 1, fig. 2, fig. 3 and fig. 4, a pump device 100, the pump device 100 includes: an air bag 110, a first valve core 120, and a second valve core 130. The air bag 110 can elastically expand and contract, and the air bag 110 is provided with a first opening 111 and a second opening 112. The first valve core 120 includes a first sealing plate 122 and a first seat 121 disposed on the airbag 110. The first base 121 is provided with a first vent 1211 communicating with the first opening 111. Second valve spool 130 includes a second sealing flap 132 and a second seat 131 disposed on bladder 110. The second base 131 is provided with a second vent 1311 for communicating with the second opening 112 and the air port 210 of the bag 200, respectively. The expansion of the air bag 110 can trigger the first sealing sheet 122 and the second sealing sheet 132 to correspondingly control the opening and closing of the first vent 1211 and the second vent 1311, and when the air bag 110 is expanded or compressed, the opening and closing state of the first vent 1211 is opposite to the opening and closing state of the second vent 1311.

In the pump apparatus 100, during evacuation or pressurization, the second base 131 is mounted on the bag 200, such that the second vent 1311 is in communication with the air port 210; after the communication, the airbag 110 is operated to expand and contract. When the air bag 110 is compressed or expanded, the first sealing sheet 122 and the second sealing sheet 132 can be triggered to correspondingly control the opening and closing of the first vent 1211 and the second vent 1311, and the opening and closing states of the first vent 1211 and the second vent 1311 are opposite, so that when the air bag 110 is compressed, if the first vent 1211 is in an open state, the second vent 1311 is in a closed state, and at this time, gas is exhausted from the first vent 1211 to the atmosphere; when the air bag 110 is expanded, the first vent 1211 is closed and the second vent 1311 is opened, and at this time, the air bag 110 sucks air from the bag body 200 to evacuate the bag body 200. On the contrary, when the airbag 110 is compressed, if the first vent 1211 is in the closed state, the second vent 1311 is in the open state, and at this time, gas is discharged from the second vent 1311 into the bag body 200; when the air bag 110 is expanded, the first vent 1211 is opened and the second vent 1311 is closed, and at this time, the air bag 110 sucks air from the external atmosphere, thereby pressurizing the bag body 200. Because this embodiment adopts flexible mode, evacuates or the pressure boost operation to the 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 managed to find time or aerify in-process operation process, promotes the use of product and experiences the sense. And because the air bag 110 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 110, the storage space occupation is reduced, and the storage utilization rate of the space is improved.

It should be noted that the elastic expansion of the airbag 110 is understood as: after compression, the balloon 110 will rebound to return to its pre-compressed configuration depending on 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 110 can trigger the first sealing piece 122 and the second sealing piece 132 to control the opening and closing of the first vent 1211 and the second vent 1311 correspondingly, which should be understood as follows: the expansion and contraction of the airbag 110 causes the gas at the first vent 1211 and the second vent 1311 to flow, when the first sealing piece 122 covers the first vent 1211, the flowing gas causes the pressure difference between the two sides of the first sealing piece 122 to be inconsistent, the first sealing piece 122 is attached to the first vent 1211 or is far away from the first vent 1211, and if the first sealing piece 122 is attached to the first vent 1211, the first vent 1211 is closed; if the first seal piece 122 is away from the first vent 1211, the first vent 1211 is opened. Similarly, the opening and closing principle of the second sealing sheet 132 to the second vent 1311 is similar, and is not described in detail herein. Meanwhile, the first sealing sheet 122 and the second sealing sheet 132 both have a certain elastic deformation function, and a specific material may be a rubber sheet or a plastic sheet.

In addition, the open and closed state of the first vent 1211 opposite to the open and closed state of the second vent 1311 when the airbag 110 is expanded or compressed should be understood as: when the airbag 110 is expanded or compressed, the first vent 1211 is in an open state, and the second vent 1311 is in a closed state; when first vent 1211 is in a closed state, second vent 1311 is in an open state.

Optionally, the first base 121 and the second base 131 may be mounted on the airbag 110 in the following manner: the sealing strip 230 snaps, bonds, threads, etc. Meanwhile, the second base 131 can be connected to the bag body 200 by using the sealing strip 230 for clamping or screwing. When the second base 131 adopts a threaded connection mode, the bag body 200 is provided with a base, the base is provided with an internal thread, and the second base 131 is provided with an external thread. Of course, the base may have external threads and the second base 131 may have internal threads.

Further, referring to fig. 4, 6, 7 and 8, the first valve core 120 further includes a first rotating shaft 123 rotatably connected to the first base 121. Two first seal pieces 122 are provided on the first rotation shaft 123. The first base 121 has a first chamber 1212 therein, and two opposite sides of the first base 121 are respectively provided with a first vent 1211 communicating with the first chamber 1212. The two first sealing sheets 122 are respectively located at two opposite sides of the first base 121, or the two first sealing sheets 122 are respectively located at two opposite sides of the first chamber 1212, and when one first vent 1211 is covered with the first sealing sheet 122, the other first vent 1211 is in an open state. As can be seen, only one first vent 1211 can be covered by the first seal 122 between the two first vents 1211. This ensures that only one first vent 1211 is open and closed during evacuation or pressurization, and the other vent functions only as a vent. Because the two first sealing sheets 122 are respectively located on two opposite surfaces of the first base 121, or the two first sealing sheets 122 are respectively located on two opposite sidewalls in the first chamber 1212, when the airbag 110 is compressed, one first sealing sheet 122 is tightly attached to the first vent 1211, and the other first sealing sheet 122 is far away from the first vent 1211, so that two states, namely evacuation and pressurization, can be realized on the first base 121, and a structural basis is provided for realizing the back-and-forth switching between the evacuation operation and the pressurization operation.

It should be noted that the open state of the first vent 1211 is understood as follows: the first sealing sheet 122 does not cover the first vent 1211.

Further, referring to fig. 4, 9, 10 and 11, the second valve core 130 further includes a second shaft 133 rotatably connected to the second base 131. Two second sealing pieces 132 are arranged on the second rotating shaft 133. The second base 131 is provided with a second chamber 1312, and two opposite side surfaces of the second base 131 are provided with second vents 1311 communicated with the first chamber 1212. Two second sealing plates 132 are respectively located at opposite sides of the second base 131, or two second sealing plates 132 are respectively located at opposite sides of the second chamber 1312. When one of the second vents 1311 is covered with the second seal fin 132, the other second vent 1311 is in an open state. Because the two second sealing sheets 132 are respectively located on two opposite surfaces of the second base 131, or the two second sealing sheets 132 are respectively located on two opposite sidewalls in the second chamber 1312, when the airbag 110 is compressed, one second sealing sheet 132 is tightly attached to the second vent 1311, and the other second sealing sheet 132 is far away from the second vent 1311, so that two states, namely evacuation and pressurization, can be realized on the second base 131, 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 123 and the second rotating shaft 133 can rotate independently, that is, the first rotating shaft 123 and the second rotating shaft 133 can rotate independently, so that the pump body device 100 can switch between the evacuation function and the pressurization function. For example, for the case where two first sealing pieces 122 are located on opposite sides of the first base 121 and two second sealing pieces 132 are located on opposite sides of the second base 131: firstly, by rotating the first rotating shaft 123, the first sealing sheet 122 at the side of the first base 121 far away from the air bag 110 covers the first vent 1211, and the other first vent 1211 is opened; next, by rotating the second rotating shaft 133 so that the second sealing sheet 132 of the second base 131 close to the airbag 110 covers the second vent 1311, at this time, the airbag 110 is expanded and contracted, and the pump body device 100 can evacuate the bag body 200; secondly, the first sealing sheet 122 at one side of the first base 121 close to the air bag 110 covers the first vent 1211 by rotating the first rotating shaft 123; next, by rotating the second rotation shaft 133 so that the second seal piece 132 of the second base 131 on the side away from the airbag 110 covers the second vent 1311, the airbag 110 is expanded and contracted, and the pump device 100 can pressurize the bag body 200. Similarly, the principle is the same for the case where two first sealing plates 122 are located in the first cavity 1212, two second sealing plates 132 are located in the second cavity 1312, two first sealing plates 122 are located on two opposite sides of the first base 121, two second sealing plates 132 are located in the second cavity 1312, two first sealing plates 122 are located in the first cavity 1212, and two second sealing plates 132 are located on two opposite sides of the second base 131, and the description is omitted.

In an embodiment, referring to fig. 5 and 9, the first base 121 and the second base 131 are respectively provided with a first stopping peg 125 and a second stopping peg 135, the first stopping peg 125 is in limit fit with the first sealing piece 122, and the second stopping peg 135 is in limit fit with the second sealing piece 132, so as to effectively prevent the first sealing piece 122 and the second sealing piece 132 from rotating excessively. Meanwhile, the first rotating shaft 123 is provided with a first mounting base 1233, and the first sealing piece 122 is mounted on the first mounting base 1233. Further, a second mounting base 1332 is provided on the second shaft 133, and the second packing 132 is mounted on the second mounting base 1332.

In one embodiment, referring to fig. 4, a first clamping portion 1231 is disposed on the first shaft 123. The second shaft 133 is provided with a second clamping portion 1331 which is clamped and matched with the first clamping portion 1231. When the first shaft 123 drives the second shaft 133 to rotate, one first air vent 1211 is covered with the first sealing piece 122, and one second air vent 1311 is covered with the second sealing piece 132. Therefore, the first rotating shaft 123 and the second rotating shaft 133 of the present embodiment rotate synchronously through the first engaging portion 1231 and the second engaging portion 1331. In the actual operation process, the first rotating shaft 123 is drawn close to the second rotating shaft 133, so that the first clamping portion 1231 is clamped and matched with the second clamping portion 1331; then, the first shaft 123 is rotated to drive the second shaft 133 to rotate synchronously. Since one of the first air vent 1211 and the second air vent 1311 is covered when the first rotating shaft 123 and the second rotating shaft 133 rotate synchronously, and the first air vent 1211 and the second air vent 1311 are opposite in the process of extending and retracting the airbag 110, the first rotating shaft 123 and the second rotating shaft 133 rotate synchronously, and the evacuation and pressurization functions can be switched rapidly.
