Embodiment 1

[0034] combine figure 1 and figure 2 , a portable container that can be repeatedly filled with compressed gas, including a bottle body 1 and a bottle cap 2 made of aluminum alloy. The two-way valve 4, the bottle cap 2, the bottle body 1 and the two-way valve 4 form a closed cavity 5; A sealing gasket 6 is provided at the fastening position; the bottle cap 2 is recessed into the bottle body 1; and the two-way valve 4 is located in the bottle body 1 .

[0035] combine figure 2 The two-way valve 4 includes a valve core 7, a valve seat 8, an oil seal 9 and a spring 10. The valve core 7 is slidably connected to the communication hole 3 of the bottle cap 2, and the valve seat 8 and the bottle cap 2 are fixed by interference fit and bonding. Connection, the valve seat 8 is located in the space enclosed by the bottle cap 2 and the bottle body 1, the valve seat 8 and the valve core 7 are connected by a spring 10, the oil seal 9 is located between the valve seat 8 and the bottle ca...

Embodiment 2

[0046] Example two such as image 3 As shown, Embodiment 2 changes the two-way valve 4 on the basis of Embodiment 1, and reduces the contact area between the valve seat 8 and the oil seal 9 on the valve seat 8, that is, the material on the valve seat 8 is partially removed and processed as image 3 As shown in the step, the compression spring 15 is installed on the step, and the compression spring 15 and the valve seat 8 are used to offset the oil seal 9. At the same time, a sealing ring 14 is set between the oil seal 9 and the bottle cap 2, and the sealing ring 14 is sleeved on the valve core. 7, the sealing ring 14 does not move or deform when the valve core 7 moves up and down.

[0047] Reduce the contact area between the valve seat 8 and the oil seal 9, and use the compression spring 15 to replace the material removal part of the valve seat 8. When the oil seal 9 is deformed by the downward movement of the valve core 7, the oil seal 9 will drive the compression spring 15 t...

Abstract

The invention relates to the technical field of outdoor equipment technologies, and particularly discloses a portable container capable of being repeatedly filled with compressed gas. The portable container comprises a bottle body and a bottle cap, wherein the bottle cap is provided with a communication hole, the communication hole is connected with a two-way valve for feeding in and discharging out oxygen, and the bottle cap, the bottle body and the two-way valve form a closed cavity. According to the scheme, oxygen filling is carried out on a vending machine through the two-way valve and thecommunication hole, the container can be repeatedly filled with the oxygen, and the problem that an oxygen bottle cannot be repeatedly used in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of outdoor equipment, in particular to a portable container that can be refilled with compressed gas. Background technique [0002] With the improvement of human living standards, more and more people choose to travel to plateau areas with unique scenery, and due to the high altitude in plateau areas, travelers often suffer from hypoxia, which is the so-called altitude sickness; To improve the situation of hypoxia, travelers often carry oxygen cylinders with them. If they stay on the plateau for a long time, they need to prepare or purchase multiple oxygen cylinders. [0003] The increase of the oxygen cylinder carried on the one hand increases the traveler's backpack weight and backpack volume. On the other hand, oxygen cylinders are usually discarded after use, causing pollution and damage to the plateau environment. Even though empty cylinders can be recycled, the recycling rate of empty cylinders is low...
