[0046] A cover body 110, wherein the upper surface of the cover body 110 is concave to form a piston groove 111, a first through hole 112 penetrating through the bottom wall of the piston groove 111 is provided at the bottom of the piston groove 111, and a first one-way plug 113 is provided at the first through hole 112;

[0047] A piston 120, the piston 120 is sealed and inserted into the piston groove 111, and can reciprocate in the piston groove 111, the piston 120 is provided with a second through hole 121, the second through hole 121 is connected to the piston groove 111, and a second one-way plug 122 is provided at the second through hole 121;

[0048] an abutment member 130 , wherein the abutment member 130 is connected to the piston 120 , and the abutment member 130 is disposed toward the first one-way plug 113 ;

[0049] The first elastic member 140 has one end connected to the piston 120 and the other end connected to the abutment member 130 . The first elastic member 140 drives the abutment member 130 so that the abutment member 130 squeezes the first one-way plug 113 at the first through hole 112 .

[0050] Through the arrangement of the above structure, when in use, the user drives the piston 120 to reciprocate in the piston groove 111. When the piston 120 moves toward the bottom of the piston groove 111, positive air pressure is generated, and the air pressure drives the first one-way plug 113 to close and the second one-way plug 122 to open. At this time, the gas between the piston 120 and the piston groove 111 is discharged to the outside along the second through hole; when the piston 120 moves away from the bottom of the piston groove 111, negative air pressure is generated, and the air pressure drives the second one-way plug 122 to close and the first one-way plug 113 to open. The gas between the cover body 110 and the accommodating body 200 is discharged to the outside through the second through hole. It is sucked between the piston 120 and the piston groove 111; the piston can be repeatedly moved to extract the gas between the cover body 110 and the containing body 200, thereby reducing the oxygen content in the containing body 200 and increasing the shelf life of the food in the containing body 200; and after the suction is completed, the piston 120 is pressed downward. At this time, the first elastic member 140 drives the abutment member 130, so that the abutment member 130 can abut against the surface of the first one-way plug 113, and squeeze the first one-way plug 113 to the first through hole 112, thereby further achieving sealing at the first through hole 112 and improving the sealing of the product.

[0051] In this embodiment, a second elastic member 150 is further included, one end of the second elastic member 150 abuts against the piston 120, and the other end of the second elastic member 150 abuts against the bottom wall of the piston groove 111. The second elastic member 150 drives the piston 120 to move in a direction away from the bottom wall of the piston groove 111. With the above-mentioned structure, when the user presses the piston 120 downward, the second elastic member 150 deforms and stores elastic potential energy. When the user releases the piston 120, the second elastic member 150 resets and lifts the piston 120, which can reduce the user's operation, make it easier to use, and save effort. The user only needs to press the piston 120 downward.

[0052] In this embodiment, the piston 120 extends downward along the edge of the second through hole 121 to form a mounting tube 123, and a first air guide channel 124 connected to the second through hole 121 is provided in the middle of the mounting tube 123. The abutment member 130 includes a sliding portion 131 and an abutment portion 132, and the sliding portion 131 can be slidably inserted in the first air guide channel 124. The two ends of the first elastic member 140 respectively abut against the upper surface of the abutment portion 132 and the end of the mounting tube 123. With the arrangement of the above structure, when in use, when the user presses the piston 120, the gas in the container can be extracted by cooperating with the first one-way plug 113 and the second one-way plug 122, and the first air guide channel 124 is connected to the second through hole 121, allowing the gas to be discharged through the second through hole 121; when the vacuum degree in the container is not high, the elastic force of the second elastic member 150 can bounce the piston 120, and the distance between the piston 120 and the bottom wall of the piston groove 111 is large, the sliding part 131 slides in the mounting tube 123, and the first elastic member 140 pushes against The connecting portion 132 moves downward, and the abutting portion 132 lightly touches the surface of the first one-way plug 113. The first one-way plug 113 can still be opened or closed normally under the action of air pressure; and when the suction is finished, the distance between the piston 120 and the bottom wall of the piston groove 111 is small, and the abutting portion 132 tightly abuts against the surface of the first one-way plug 113, which can prevent the first one-way plug 113 from opening, effectively strengthen the seal between the first one-way plug 113 and the first through hole 112, improve the sealing performance of the product, and extend the storage time of food and medicine in the product.

[0053] In this embodiment, the upper end of the sliding part 131 protrudes outward to form a first clamping block 133, and the inner wall of the lower end of the first air guide channel 124 protrudes to form a second clamping block 125. When the first elastic member 140 drives the abutting member 130 to move toward the first one-way plug 113, the first clamping block 133 abuts against the second clamping block 125. Through the above-mentioned structure, when in use, the first elastic member 140 drives the abutting member 130 to move toward the first one-way plug 113, and the first clamping block 133 cooperates with the second clamping block 125 to prevent the abutting member 130 from being detached from the mounting tube 123, thereby ensuring the stability of the product; and when the piston reciprocates, the abutting member 130 can be limited to prevent the abutting member 130 from excessively squeezing the first one-way plug 113, so that the first one-way plug 113 can be opened or closed normally, effectively sucking the gas in the container, and achieving a vacuum sealing effect.

[0054] In this embodiment, the abutment member 130 is provided with a second air guide channel 134, and the second air guide channel 134 runs through the sliding portion 131 and the abutment portion 132, and is connected to the first air guide channel 124. Through the above-mentioned structure, the second air guide channel 134 is connected to the first air guide channel 124, and when the sliding portion 131 slides in the first air guide channel 124, the gas between the piston 120 and the piston groove 111 can be discharged through the second air guide channel 134, the first air guide channel 124 and the second through hole 121, thereby ensuring the smooth flow of the exhaust passage, preventing the sliding portion 131 from being blocked and hindering the flow of gas, and ensuring the suction effect of the product.

[0055] In this embodiment, the abutment member 130 is further provided with a slot 135, and the slot 135 penetrates the sliding portion 131 along the radial direction of the second air-guiding channel 134, and the slot 135 is connected to the piston groove 111 and the second air-guiding channel 134. Through the arrangement of the above structure, when in use, the slot 135 is connected to the second air-guiding channel 134, and then can be connected to the first air-guiding channel 124 through the second air-guiding channel 134. When the sliding portion 131 is inserted into the first air-guiding channel 124, and the abutment portion 132 abuts against the surface of the first one-way plug 113, at this time, the sliding portion blocks the first air-guiding channel 124, and the surface of the first one-way plug 113 blocks the gas outlet end of the second air-guiding channel 134. The slot 135 can allow the gas between the piston 120 and the piston groove 111 to pass through, thereby entering the second air-guiding channel 134 and the first air-guiding channel 124, and then discharged through the second through hole 121, further ensuring the smooth flow of the gas channel and the suction effect of the product.

[0056] In this embodiment, a cylindrical mounting platform 114 is protruded from the bottom wall of the piston groove 111 at the edge of the first through hole 112, and the second elastic member 150 is sleeved on the mounting platform 114 and the mounting tube 123. Through the above-mentioned structural arrangement, the outer diameter of the cylindrical mounting platform 114 matches the inner diameter of the second elastic member 150, and the second elastic member 150 can be conveniently sleeved and installed on the mounting platform 114, so that the second elastic member 150 is installed more stably, thereby improving the stability and service life of the product.

[0057] In this embodiment, the piston 120 can rotate between a locking position and a release position in the piston groove 111. A first locking portion 126 is provided on the upper edge of the piston 120, and a second locking portion 115 is provided on the upper edge of the inner wall of the piston groove 111. When the piston 120 is fully inserted into the piston groove 111 and rotated to the locking position, the first locking portion 126 is locked to the second locking portion 115. When the piston 120 rotates to the release position, the first locking portion 126 is detached from the second locking portion 115. Through the arrangement of the above structure, when sucking gas, the piston 120 is rotated to the release position, at which time the first locking portion 126 is detached from the second locking portion 115, and the piston 120 can reciprocate in the piston groove 111 to suck the gas in the container, thereby increasing the vacuum degree of the product and thereby increasing the shelf life of the food, medicine, etc. in the product; and when the suction action is completed, the user can press the piston 120 downward and rotate the piston 120 to the locking position, at which time the first locking portion 126 is locked to the second locking portion 115, so that the position of the piston 120 and the piston groove 111 can be relatively fixed, and the abutment portion 132 is tightly pressed against the surface of the first one-way plug 113 under the action of the first elastic member 140, thereby preventing the first one-way plug 113 from being detached from the first through hole 112, thereby improving the air tightness between the first one-way plug 113 and the first through hole 112 and thereby improving the air tightness of the product.

[0058] In this embodiment, an exhaust component 160 is further included. An exhaust hole 116 is provided on the surface of the cover body 110. The exhaust component 160 is arranged at the exhaust hole 116 and is used to connect the accommodating cavity 210 of the accommodating body 200 and the external atmosphere. Through the above-mentioned structure, when the user needs to open the cover body 110, the exhaust component 160 can be used to connect the atmosphere with the accommodating cavity 210 of the accommodating body 200 to release the air pressure, so that the user can open the cover body 110 more easily, which is convenient for the user to operate, and is simpler and more labor-saving to use.
