Portable gas cylinder switch assembly

Abstract

The invention relates to a portable gas cylinder switch assembly. The portable gas cylinder switching assembly comprises a switch body, a gas nozzle, a pilot valve, a positioning sleeve, a microswitch and a gas transmission display. The portable gas cylinder switching assembly can be used in a household medical oxygen cylinder and also in a bottle filled with other gases. When the assembly is used in the household medical oxygen cylinder, the gas nozzle is driven by rotation of a high-pressure knob of the pilot valve to rotate along a thread and stretch into a connecting inner chamber side of the oxygen cylinder of the switch body. The oxygen in the oxygen bottle enters the inner chamber of the pilot valve. As a gaseous core is closely adhered to a seal ring, the oxygen in the cylinder does not overflow. When a low-pressure knob is screwed so that the valve touches the gaseous core and leaves away from the seal ring, the oxygen enters a micromotion area, enters a gap between the small-diameter cylinder of the positioning sleeve and the inner wall of the switch body from a gas outlet and then enters the gas transmission display through the gas outlet of the switch body. When a floater in the air passage floats, the oxygen begins to overflow. The portable gas cylinder switching assembly has the advantages of reasonable structure, full utilization of materials, no waste, convenience of use, and popularization.

Description

Technical field: [0001] The invention relates to a portable gas cylinder, in particular to a portable gas cylinder switch assembly. Background technique: [0002] With the take-off of the national economy and the improvement of people's living standards, people's attention began to focus on the improvement of the quality of life. The improvement of hygiene, health care, and medical services has become the focus of heated discussions. Patients who originally needed to receive oxygen in the hospital are now Treatment can be obtained at home by using small medical oxygen cylinders, which not only facilitates the patients but also reduces the pressure on the hospital. However, the sealing of medical oxygen cylinders currently available in the market is too simple. The sealing structure is only to press the sealing copper sheet with the cover and the "O" ring under the sealing copper sheet.

Problems solved by technology

However, the sealing of medical oxygen cylinders currently available in the market is too simple. The sealing structure is only to press the sealing copper sheet with the cover and the "O" ring under the sealing copper sheet. Once the sealing copper sheet is pierced, the oxygen in the bottle will start to release immediately. , there is no sign of release, and the release is often started before the patient is ready. When the patient's family members wake up, the oxygen in the bottle is almost released, and there is not much to save. It can be said that it comes and goes in a hurry. In the patient Oxygen cannot be obtained when there is an urgent need for oxygen infusion, which delays the best time for rescue, and the consequences are extremely serious. This is an urgent problem to be solved
