DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 5 As shown, this embodiment discloses a high-pressure medium container, including a bottle body 1, a plug 2, a pump body 3, a nozzle 4, a sealing gasket 5 and a spring 6. The bottle body 1 and the plug 2 are fixedly connected to form a storage space 7 with an open upper end. The bottle body 1 and the plug 2 are both made of plastic and are connected together by ultrasonic welding. The sealing gasket 5 is a soft rubber sealing gasket, the pump body 3 and the nozzle 4 are made of plastic, and the spring 6 is made of plastic or metal.

[0023] The pump body 3, sealing gasket 5 and spring 6 are located in the storage space 7, and the nozzle 4 is partially located in the storage space 7. The opening is formed in the opening seat 21 of the plug 2, and the opening is the center hole of the opening seat 21. The storage space 7 refers to the remaining space in the lower part except the upper end opening.

[0024] The storage space 7 contains a high-pressure medium. The high-pressure medium can be a high-pressure gas or a high-pressure liquid. The high-pressure medium can be a condensing agent, high-pressure oxygen, high-pressure hydrogen, high-pressure nitrogen, or other medium with storage conditions above atmospheric pressure, or a high-pressure cosmetic material, a high-pressure beverage, or other high-pressure liquid. High-pressure cosmetic material refers to a mixture of high-pressure gas and cosmetics, high-pressure beverage refers to a mixture of high-pressure gas and beverage, and other high-pressure liquids refer to a mixture of high-pressure gas and liquids other than cosmetics or beverages. The pressure of the high-pressure medium is greater than standard atmospheric pressure.

[0025] The filling pressure of high-pressure medium is 3-10kg. The high-pressure medium is filled to no more than 90% of the internal capacity and can be used once or multiple times. The internal pressure will vary depending on the filling medium each time, but it will not affect the spraying speed and volume of the medium until all the medium is sprayed out.

[0026] The plug 2 includes an opening seat 21 and a first transition section 23 located below the opening seat 21. The inner wall of the plug 2 is provided with a connecting seat 22, which is located below the first transition section 23. The connecting seat 22 is concave. The opening seat 21 and the first transition section 23 cooperate to form a step portion for accommodating the sealing gasket 5. The lower end of the sealing gasket 5 extends beyond the step portion. The outer diameter of the sealing gasket 5 is less than or equal to the inner diameter of the first transition section 23. The inner diameter of the connecting seat 22 is greater than the inner diameter of the first transition section 23, that is, the connecting seat 22 is located below the first transition section 23 and is relatively located on the periphery of the inner edge of the first transition section 23.

[0027] The pump body 3 includes a second pipe 32, a second transition section 33 and a first pipe 31 integrally formed from top to bottom. The inner diameter of the second pipe 32 is larger than the outer diameter of the first pipe 31, and the lower end of the second pipe 32 and the upper end of the first pipe 31 are connected by the second transition section 33.

[0028] The pump body 3 is connected to the plug 2. Specifically, the pump body 3 is provided with a connector 321 that cooperates with the connector seat 22. The connector 321 is provided at the upper outer edge of the second pipe 32. The connector 321 protrudes outward from the upper outer edge of the second pipe 32 and is snap-connected to the recessed connector seat 22. When the two are snap-connected, the upper end surface of the second pipe 32 abuts the lower end surface of the sealing gasket 5. Specifically, at least the upper inner edge of the second pipe 32 abuts the lower outer edge of the sealing gasket 5, ensuring a secure installation of the sealing gasket 5.

[0029] The nozzle 4 includes a protrusion 41, a guide body 43 located above the protrusion 41, and a guide seat 42 located below the protrusion 41. The top of the nozzle 4 (i.e., the upper end of the guide body 43) extends beyond the upper opening of the plug 2. The outer diameter of the guide body 43 is smaller than the diameter of the opening. The sidewall of the guide body 43 is provided with a through hole 431. The guide body 43 has a flow channel 432 along its central axis. The through hole 431 connects to the flow channel 432. There is at least one through hole 431 located near the protrusion 41.

[0030] The nozzle 4 and the pump body 3 are connected by a spring 6, which is located outside the guide seat 42. The upper end of the spring 6 abuts against the protrusion 41, and the lower end of the spring 6 abuts against the second transition section 33. The outer diameter of the guide seat 42 is smaller than the inner diameter of the first pipe 31, so the guide seat 42 does not block the first pipe 31 during its downward movement.

[0031] The sealing gasket 5 is sealed between the opening seat 21 and the protrusion 41. In the closed state, the spring 6 presses against the nozzle 4 to separate the flow channel 432 and the storage space 7, and the high-pressure medium cannot pass through the protrusion 41 and enter the through hole 431.

[0032] In the open state, the spring 6 is compressed, causing the nozzle 4 to move downward along its central axis, connecting the flow channel 432 with the storage space 7. In the open state, the protrusion 41 is disengaged from the sealing gasket 5, and the through-hole 431 is at least partially located below the sealing gasket 5. In the closed state, the pressure in the flow channel 432 is at standard atmospheric pressure. The outlet 43 is connected to an external nozzle. During use, pressing the nozzle to open it causes the nozzle 4 to move downward. Because the internal pressure of the container is greater than atmospheric pressure, the medium is ejected along the first pipe 31, the second pipe 32, the through-hole 431, the flow channel 432, and the nozzle.

[0033] The sealing gasket 5 is interference-fitted with the outer wall of the outlet body 43. This ensures that the medium will only be ejected from the flow channel 432 during the injection process, and will not be ejected from the gap between the sealing gasket 5 and the outlet body 43.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
