[Prior Art] The sealed container can be used for placing food, precision instruments, accessories, musical instruments and other materials that are damp-proof. After the air is extracted, the moisture contacted by the articles can be reduced, thereby increasing the shelf life or preventing the articles from being damaged by moisture. . The sealed container generally has a cover body and a container can. The cover body is used for closing the container can, and the cover body is provided with an umbrella valve and at least one air hole penetrating through the cover body, and the umbrella valve shields the air hole. According to the user, the user can cover the umbrella valve by providing a negative pressure environment, and the air in the container can be pressed by the air hole to bend and leave the container, so that the container can be formed in the container. The vacuum space of the vacuum, and when the air pressure outside the container is larger than the inside of the container, the air will press the umbrella valve to tightly close the air hole, thereby maintaining the vacuum in the container. It is customary for the container to form a vacuum space with a certain degree of vacuum. The user must allow the piston device to cover the umbrella valve, and at the same time pull the piston device a plurality of times, which is quite inconvenient to use, and the user is easy because Negligence or laziness results in insufficient vacuum in the can, leaving the container still visibly humid, which can result in faster than expected preservation of the contents of the can.

The piston device includes at least one rubber piston relative to the shank, and each of the rubber pistons defines a variable space, and the rubber piston can be driven to change the volume of the variable space, and the rubber The piston is sleeved with the shank, and the one-way valve device has a plurality of two-way flow passages opposite to the variable space and two check valves disposed at opposite ends of the one-way flow passage and having the same stop direction Ci And the one-way flow path is in communication with the variable space. According to this, the mandrel can drive the eccentric seat to rotate, and the eccentric seat is eccentrically rotated to swing the shank of the piston crank back and forth, so that the shank can drive the rubber piston to change the volume of the variable space. That is, it can change the air pressure in the one-way flow passage to allow the air to pass through the one-way flow passage in a single direction by the two check valves to form an air suction device. [Embodiment] In order to enable your members to understand the characteristics, purpose and efficacy of the present invention, there is a better understanding and recognition of the 2010 201000371 ice, and the better real county j with the schema description as follows: read "Figure i" and "Figure 2 shows that the present invention is an exhaust garment, comprising a rotary power source, 10, an eccentric seat 20, a piston crank 30, a piston device 4〇, and a 1-way valve device 5〇, wherein the rotation There is a mandrel 11 which provides a rotational power. The power supply can be widely used as a motor. The battery can be rotated by a battery, an external power supply, and the spindle 11 can be rotated. Provides rotational power. The eccentric seat 20 has an input end 21 and a wheel end 22, and the input end 21 and the output end 22 are eccentric rt, and the input end 21 is When the mandrel 11 is sleeved, the piston is bent, and the connecting end 31 is disposed laterally with respect to the connecting end 31 to the shank 32', wherein the preferred number of the shanks 32 is three and The lateral direction of the connecting end 31 is self-distributed, and the output end 22 of the connecting end of the connecting end is sleeved and fixed. Therefore, when the core (4) rotates, the piston crank 30 will swing up and down due to eccentric rotation, that is, relative to the connection. The shank 32 disposed laterally of the end 31 is driven to swing back and forth. In addition, the present invention may further include a crank front cover 60 that is disposed to fit the rotary power source 1G, and the crank front cover 6Q has a hollow accommodation space 61 'the hollow accommodation space 61 is available The eccentric seat 20 is provided with the plug crank 30 to protect it. Referring to FIG. 4 again, the piston device 4 includes a quantity of at least a rubber piston 4 relative to the shank 32 and each of the rubber rafts 8 201000371. The plug 41 defines a variable space 411. Further, the piston device 4A may include a carrier plate 42'. The rubber piston 41 may be extended outwardly from one side of the carrier plate 42 to form 'as shown in the drawing. The rubber piston 41 of the piston device may be three. And disposed relative to the three shanks 32, and the three rubber pistons 41 are evenly distributed on the carrier plate 42. The present invention may further include a piston ring cover 70, the piston ring cover 7 is provided with at least one piston seat 71, the piston seat 71 is adapted to cover the rubber piston 41, and as shown, the piston seat 71 can Three and evenly distributed in the piston ring cover 7〇.
