Problems solved by technology

However, the traditional oxygen inhalation method is far from being able to meet people's needs. For this reason, after decades of research, relevant experts at home and abroad have developed alternative products that can replace traditional, bulky and incapable of carrying oxygen cylinders. These products are Oxygen bags, small oxygen tanks and household portable oxygen concentrators will become one of the must-haves in people's future life
But oxygen bag and oxygen tank all have certain pressure, and the one, can not be carried on public transport, has limited traveler, old, infirm use on the road; The 2nd, because oxygen bag and oxygen tank are all disposable , leading to an increase in cost, which is unbearable for ordinary families
At present, the oxygen Lide portable oxygen generator used in domestic sales has brought great convenience to family health care, but there are problems of large size, inconvenient portability, and high price; and the oxygen generator cannot be put into the oxygen generator in advance. In the device, it needs to be used and put away immediately. If the oxygen generator is put in in advance, the internal pressure will be too high, which will be unsafe, and it cannot be used tilted or upside down, which brings inconvenience to the user.

Embodiment 1

[0014] Embodiment 1, this is an embodiment of the gas-liquid-solid separation control valve involved in the first technical solution of the present invention, and its structural schematic diagram refers to FIG. 1 . As can be seen from Figure 1, the gas, liquid and solid separation control valve is mainly composed of a valve body 3, a valve stem 17, a water valve core 10, a valve core sleeve 9 sleeved on the water valve core, a valve stem guide pipe 13, Located at the lower end of the valve stem guide pipe 13 and the water inlet hole 11 on the wall corresponding to the water valve core, the water vapor isolation sealing sleeve 12, and the air intake hole 14 located on the valve stem guide pipe wall; located on the upper part of the valve stem guide pipe 13 The filter air inlet 16 on the wall, the microporous filter membrane 15 between the valve stem 17 corresponding to the upper part of the filter inlet hole and the valve stem guide pipe 13, and the microporous filter membrane 1...

Embodiment 2

[0017] Embodiment 2, this is an embodiment of the portable chemical oxygen generator described in the second technical solution, refer to Fig. 2 and Fig. 3 . Fig. 2 is a schematic structural diagram of a portable chemical oxygen generator in a non-practical state, and Fig. 3 is a schematic diagram of an exploded structure of a portable chemical oxygen generator. It can be seen from these two drawings that all the oxygen generators are connected by threaded connection. It consists of an oxygen chamber 1, a preparation box 7 fixed therein, a humidification filter 4, an oxygen inhalation catheter 5, an oxygen inhalation nasal plug 6, a cover 23 and a gas, liquid and solid separation control valve. The mouth of the preparation box is connected with the lower end of the valve stem guide pipe of the gas, liquid, and solid separation control valve in a threaded manner, and the upper end of the oxygen generating chamber 1 is fixedly connected with the inner wall of the valve correspon...

Abstract

The invention discloses a gas-liquid-solid separating controlling valve and relative portable chemical oxygen producer, comprising a valve body 3, a water valve element 10, a valve element sheath 9, a compressing cover 20, a valve rod 17 and a button 21. The invention is characterized in that: the invention has a valve rod guide tube 13 whose lower end is arranged with a water inlet 11, a water feeding gas-insulated sealing sheath 12 and a porous filter membrane 15; the wall of the valve rod guide tube is arranged with an air inlet 14 and a filter air inlet 16; the upper chamber of the valve is arranged with a gas valve element 18, a spring 19 and an air outlet 22. The portable chemical oxygen producer is formed by an oxygen-generating room 1, a cover 23, an oxygen inlet tube 5, an oxygen inlet nose plug 6, a gas-liquid-solid separating controlling valve and an agent box 7. The invention can control the separation between liquid and solid, and between the liquid and gas. The invention presets the oxygen agent into the agent box.

Description

Technical field: [0001] The invention relates to a gas, liquid and solid separation control valve and a portable chemical oxygen generator using the valve, which belongs to the technology in the field of gas-liquid control and the technology in the field of medical and health care machinery. Background technique: [0002] The current control valve consists of a single liquid control valve or a single gas control valve. They can only be used to control the flow or closure of liquid and gas. Since gas-liquid separation cannot be performed, it is impossible to control liquid and gas at the same time. Therefore, Also just can't be applied to the field of not only controlling liquid but also controlling solid and gas. [0003] Oxygen is the source of sustaining life. It can oxidize the substances people eat into energy to meet the needs of human tissues and organs. Humans need supplemental oxygen for various reasons, such as mental workers, workers in high altitude areas, touris...
