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 and solid separation control valve involved in the first technical solution of the present invention, its structural schematic diagram refers to figure 1 . pass figure 1 It can be seen that 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, and a valve stem guide pipe 13, which are positioned at the valve stem. The water inlet hole 11 on the lower end of the guide pipe 13 and the wall corresponding to the water valve core, the water-air isolation sealing sleeve 12, the air inlet 14 located on the water-air isolation sealing sleeve 12; The filter air inlet 16 on the top, 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 tube 13, and the microporous filter membrane 15 extends downward to the val...

Embodiment 2

[0017] Embodiment 2, this is an embodiment of the portable chemical oxygen generator described in the second technical solution, refer to figure 2 and image 3 . figure 2 It is a schematic diagram of the structure of a portable chemical oxygen generator in a non-practical state, image 3 It is a schematic diagram of the decomposition 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 ...

Abstract

The invention discloses a gas, liquid and solid separation control valve and a portable chemical oxygen generator using the valve, belonging to gas-liquid control and medical and health care technologies. This valve is made up of valve body (3), water spool (10), spool cover (9), gland (20), valve stem (17) and knob (21). It is characterized in that a valve stem guide pipe (13) is set, and a water inlet hole (11) is set at its lower end, a water-gas isolation sealing sleeve (12), a microporous filter membrane (15), and a water-air isolation sealing sleeve (12) are provided. There is an air inlet (14) on the top, a filter air inlet (16) on the guide pipe wall of the valve stem, and an air valve core (18), a spring (19) and an air outlet (22) in the upper chamber of the valve body. . The portable chemical oxygen generator consists of an oxygen generator chamber (1), a cover (23), an oxygen inhalation catheter (5), an oxygen inhalation nasal plug (6), a gas, liquid and solid separation control valve and a preparation box (7). The gas, liquid, and solid separation control valve can control liquid, solid separation, liquid, and gas separation respectively. The portable chemical oxygen generator can put the oxygen generator into the preparation box in advance, without any pressure before use, which is convenient for travel and home use. Come to great convenience.

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...
