In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components thereof have been omitted.

The embodiment of the invention provides an inflation assembly which can be used for inflating a container, for example, a juice cup filled with juice can be inflated, so that the juice is fully mixed with gas, the taste of the juice is improved, and the juice is tasty and spicy.

As shown in fig. 1 to 4, the inflation assembly of the embodiment of the present invention includes an inflation seat 1, an inflation tube 2, a puncture needle 3, a compressed gas cylinder 4, and an adjustment cap 5. The inflatable seat 1 is internally provided with a cavity 14 which at least penetrates through the upper end of the inflatable seat 1, the first end of the inflatable tube 2 is connected to the lower end of the inflatable seat 1, the second end of the inflatable tube 2 forms an inflation port 21, the puncture needle 3 is arranged on the inflatable seat 1 and is communicated with the first end of the inflatable tube 2, at least the needle head of the puncture needle 3 stretches into the cavity 14, the compressed gas bottle 4 can be arranged in the cavity 14, the bottle mouth of the compressed gas bottle 4 is opposite to the needle head of the puncture needle 3, the adjusting cover 5 can be adjustably arranged on the inflatable seat 1, namely, the adjusting cover 5 can move on the inflatable seat 1 to change the position of the adjusting cover 5 relative to the inflatable seat 1, when the adjusting cover 5 moves downwards relative to the inflatable seat 1, the compressed gas bottle 4 can be pushed to move towards the puncture needle 3, the bottle mouth of the compressed gas bottle 4 is enabled to abut against the puncture needle 3, gas in the compressed gas bottle 4 is enabled to enter the inflatable tube 2 through the puncture needle 3, and gas in the compressed gas bottle 4 is discharged from the inflation port 21 of the inflatable tube 2 to be inflated by the inflatable part.

The inflation assembly provided by the embodiment of the invention has a simple structure, is convenient to inflate, can be applied to the juice cup to inflate juice in the juice cup, ensures that the juice has a refreshing and spicy taste, and improves the drinking experience of users.

In some embodiments, with continued reference to fig. 1-3, the first tube aperture of the first end of the inflation tube 2 is larger than the second tube aperture of the second end of the inflation tube 2, such that a step is formed therebetween, and a gas check valve 6 is disposed in the first tube aperture to allow gas to enter the second tube aperture only from the spike 3. Through setting up gaseous check valve 6, after the inflation is accomplished, can prevent that the gas in the gas tube 2 from upwards flowing, and then can effectively avoid the liquid in the container (e.g. juice glass) to flow backwards through gas tube 2.

In some embodiments, as shown in fig. 1 to 4, the gas check valve 6 includes a valve core 61 and an elastic member 62, both ends of the elastic member 62 respectively abut against the valve core 61 and the stepped portion to apply an elastic force to the valve core 61 to seal the valve core 61 against the trailing end of the lancet 3. That is, the valve core 61 keeps the state of blocking the tail end of the puncture needle 3 without the action of external force, and the puncture needle 3 is isolated from the inside of the inflation tube 2. When the puncture needle 3 punctures the compressed gas cylinder 4, the gas in the compressed gas cylinder 4 enters the puncture needle 3 and acts on the valve core 61 to push the valve core 61 to overcome the elastic force of the elastic piece 62 so as to separate the valve core 61 from the tail end of the puncture needle 3, the puncture needle 3 is communicated with the inside of the inflation tube 2, and the gas in the compressed gas cylinder 4 enters the inflation tube 2 through the gas one-way valve 6. The specific structure of the elastic member 62 is not limited, and for example, the elastic member can be a spring, and the spring has a simple structure, convenient material taking and good elastic effect.

In some embodiments, in order to stabilize the valve core 61, the valve core 61 is smoothly moved in the first orifice as the valve cavity, the gas check valve 6 further includes a valve core holder 63, the valve core 61 including a head portion and a tail portion, the head portion having a spherical surface for sealing the tail end of the lancet 3, a neck portion connected between the head portion and the tail portion such that an annular groove surrounding the neck portion is formed therebetween, the valve core holder 63 having an inner hole whose inner wall is provided with protrusions along its circumference, the neck portion and the tail portion of the valve core 61 being provided in the inner hole, and the protrusions being embedded in the annular groove, see fig. 1 to 4. One end of a spring as the elastic member 62 may be connected to the outer periphery of the spool frame 63, and the other end of the spring is connected to the stepped portion. Thus, when the spring is compressed or released, the valve core frame 63 is pushed to drive the valve core 61 to move up and down in the first pipe hole smoothly, so as to seal the puncture needle 3 or enable the gas in the puncture needle 3 to be discharged to the second pipe hole.

With continued reference to fig. 1 to 4, the lower end of the inflatable seat 1 is provided with a mounting cavity, the inner wall of the mounting cavity is provided with internal threads 13, the outer wall of the first end of the inflatable tube 2 is provided with external threads 92, and the first end of the inflatable tube 2 is in threaded connection with the mounting cavity. So as to facilitate the disassembly and assembly of the inflation tube 2 and the inflation seat 1 and the maintenance of products. The cross-sectional shape of the mounting cavity may be circular in order to facilitate the threaded connection. A sealing ring 64 is arranged between the inflation tube 2 and the inflation seat 1 to prevent the gas from leaking. Meanwhile, liquid in the container to be inflated can be prevented from entering the inflation tube 2, and inflation efficiency is affected. The number of the sealing rings 64 can be two, and the two sealing rings 64 are respectively arranged between the upper end and the lower end of the inflation tube 2 and the cavity wall of the installation cavity. In particular, the sealing ring 64 at the upper end thereof is located between the end face of the first end of the inflation tube 2 and the cavity bottom wall of the mounting cavity (the cavity wall facing the cavity opening is defined as cavity bottom wall). So set up, can further promote sealed effect.

With continued reference to fig. 1-3, the spike 3 is disposed within the inflatable seat 1 between the chamber 14 and the mounting cavity, and the needle of the spike 3 extends into the chamber 14. The tail end of the puncture needle 3 is communicated with the first end of the inflation tube 2 through an air hole 31. That is, an air hole 31 is arranged in the inflatable seat 1 for communicating the tail end of the puncture needle 3 with the inflatable tube 2. The lower end of the air hole 31 penetrates through the middle of the cavity bottom of the installation cavity. The valve core 61 seals the tail end of the puncture needle 3 by sealing the lower end of the air hole 31. In order to realize the sealing and the bonding of the valve core 61 and the part provided with the air hole 31 in the middle of the cavity bottom of the installation cavity, the head part of the valve core 61 forms a spherical convex surface, and the surface of the middle of the cavity bottom forms a concave surface matched with the head part of the valve core 61.
