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

As shown in fig. 1 to 4, the inflation assembly of the embodiment of the present invention includes an inflation socket 1, an inflation tube 2, a puncture needle 3, a compressed gas cylinder 4, and an adjustment cap 5. A cavity 14 at least penetrating to the upper end of the inflating seat 1 is arranged in the inflating seat 1; the first end of the inflation tube 2 is connected with the lower end of the inflation seat 1, and the second end of the inflation tube 2 forms an inflation opening 21; the puncture needle 3 is arranged on the inflation seat 1 and is communicated with the first end of the inflation tube 2, and at least the needle head of the puncture needle 3 extends into the cavity 14; a compressed gas cylinder 4 can be arranged in the chamber 14, and the mouth of the compressed gas cylinder 4 is opposite to the needle of the puncture needle 3; the adjusting cover 5 is adjustably arranged on the inflating seat 1, that is, the adjusting cover 5 can move on the inflating seat 1 to change the position of the adjusting cover 5 relative to the inflating seat 1, when the adjusting cover 5 moves downwards relative to the inflating seat 1, the compressed gas cylinder 4 can be pushed to move towards the puncture needle 3, so that the nozzle of the compressed gas cylinder 4 is abutted against the puncture needle 3, the puncture needle 3 punctures the compressed gas cylinder 4, and the gas in the compressed gas cylinder 4 enters the inflating tube 2 through the puncture needle 3 and is discharged from the inflating port 21 of the inflating tube 2 to inflate the part to be inflated.

The inflating assembly provided by the embodiment of the invention is simple in structure and convenient and fast in inflating operation, and can be applied to a juice cup to inflate juice in the juice cup, so that the juice has a refreshing and spicy taste, and the drinking experience of a user is improved.

In some embodiments, with continued reference to fig. 1-3, the first tube aperture of the first end of the gas-filled tube 2 is larger than the second tube aperture of the second end of the gas-filled tube 2, such that a step is formed therebetween; the first tube hole is internally provided with a gas one-way valve 6 which only allows gas to enter the second tube hole from the puncture needle 3. Through setting up gaseous check valve 6, after aerifing the completion, can prevent that the gas in the gas tube 2 from upwards flowing, and then can effectively avoid the liquid in the container (for example juice glass) to flow backwards via 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, and two ends of the elastic member 62 respectively abut against the valve core 61 and the step portion to apply an elastic force to the valve core 61 to seal the valve core 61 with the tail end of the puncture needle 3. That is, under the condition of no external force, the valve core 61 keeps the state of blocking the tail end of the puncture needle 3, and the puncture needle 3 is isolated from the inner part 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 element 62 to enable the valve core 61 to be separated from the tail end of the puncture needle 3, the puncture needle 3 is communicated with the interior of the gas filling pipe 2, and the gas in the compressed gas cylinder 4 enters the gas filling pipe 2 through the gas one-way valve 6. The specific structure of the elastic member 62 is not limited, and may be, for example, a spring, which has a simple structure, convenient material collection and good elastic effect.

In some embodiments, in order to stabilize the valve core 61, such that the valve core 61 can move smoothly in the first pipe hole as a valve cavity, the gas check valve 6 further comprises a valve core frame 63, wherein the valve core 61 comprises a head part and a tail part, and the head part is provided with a spherical surface for sealing the tail end of the puncture needle 3; the neck part is connected between the head part and the tail part, so that an annular groove surrounding the neck part is formed between the head part and the tail part; the spool frame 63 has an inner hole, the inner wall of which is provided with protrusions along the circumferential direction thereof, the neck and tail of the spool 61 are provided in the inner hole, and the protrusions are embedded in the annular grooves, see fig. 1 to 4. One end of a spring as the elastic member 62 may be connected to the outer circumference 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 smoothly move up and down in the first pipe hole so as to block the puncture needle 3 or make the gas in the puncture needle 3 externally discharged to the second pipe hole.

A sealing ring 64 is arranged between the inflation tube 2 and the inflation seat 1 to prevent the gas from leaking. Meanwhile, the liquid in the container to be inflated can be prevented from entering the inflation tube 2, and the inflation efficiency is prevented from being influenced. The number of the sealing rings 64 can be two, and the two sealing rings 64 are respectively arranged between the inflation tube 2 and the upper end and the lower end of the cavity wall of the installation cavity. Specifically, the upper end seal ring 64 is located between the end face of the first end of the inflation tube 2 and the bottom wall of the installation cavity (the cavity wall facing the cavity opening is defined as the bottom wall). So set up, can further promote sealed effect.

It should be noted that, the assembly sequence of the components of the gas charging assembly 400 and the assembly sequence of the gas charging assembly 400 and the juice glass 300 are not specifically limited in the embodiments of the present invention, as long as the final purpose can be achieved. Similarly, the sequence of assembling the components of the inflation assembly 400 and the material pressing rod 9 is not particularly limited in the embodiments of the present invention, as long as the final purpose can be achieved.

The inflation process of the inflation assembly 400 of the present invention will now be described with reference to the drawings.

The gas charging assembly 400 is first loaded into the juice glass 300 and prior to charging the gas charging assembly 400, as shown in fig. 2 and 3, the compressed gas cylinder 4 is positioned above the spike 3 and the spike 3 does not pierce the compressed gas cylinder 4. The adjusting cover 5 does not press against the push plate 84, the elastic body 83 is in a release state, and the sealing member 82 does not press against the pressure relief hole 81. When the adjusting cover 5 is screwed downwards, the top of the adjusting cover 5 first presses against the push plate 84, the push plate 84 moves downwards and compresses the elastic body 83, the elastic body 83 presses the sealing member 82, the sealing member 82 seals the pressure relief hole 81, and the air in the juice glass 300 cannot leak out. Continuing to rotate the adjusting cover 5 downwards, the adjusting cover pushes the bottom of the compressed gas cylinder 4 downwards to drive the compressed gas cylinder 4 to move downwards, the mouth of the compressed gas cylinder 4 gradually abuts against the pricking pin 3 and is pierced by the pricking pin 3, referring to fig. 1 and 2, and in combination with fig. 12, gas in the compressed gas cylinder 4 enters the pricking pin 3 and pushes the valve element 61 downwards to open the gas one-way valve 6, and the gas enters the gas-filled tube 2 through the pricking pin 3 and enters the fruit juice through the gas-filled port 21 of the gas-filled tube 2 to complete the inflation of the fruit juice. The fruit juice has a refreshing and spicy taste, and the user experience is improved. When the air pressure above the juice in the juice cup 300 is too large and is larger than the preset pressure, the air in the juice cup 300 pushes the sealing element 82 upwards through the pressure relief hole 81, the sealing element 82 pushes the elastic body 83 to compress, and the pressure relief hole 81 is opened to realize pressure relief. The aerated juice glass 300 can be sealed by a cup cover 301.
