Problems solved by technology

However, the structure of the solenoid valve is complicated, the performance is not stable enough, and the cost is high
Using the two valves of solenoid valve 160 and flow valve 1207 to switch the atomization gas circuit and adjust the oxygen flow rate also results in complex structure and increased cost

Embodiment 1

[0037] image 3 It is a structural schematic diagram of the oxygen generator in Embodiment 1 of the present invention.

[0038] Such as image 3 As shown, the oxygen generator 2 of Embodiment 1 of the present invention includes a gas source 10 , an oxygen generator unit 20 , an atomization unit 30 , and a combination valve 40 .

[0039] In this embodiment, the air source 10 includes an air compressor, which inhales air, generates compressed air, and supplies the compressed air to the oxygen generating unit 20 or the atomizing unit 30 . The oxygen generating unit 20 converts the compressed air output from the air source 10 into oxygen. The atomization unit 30 blows the compressed air output from the air source 10 to the atomization cup 301 to generate drug mist, which is delivered to the atomization outlet 52 for use by the patient.

[0040] The air output from the air source 10 and the oxygen output from the oxygen generating unit 20 are input into the combined valve 40 , a...

Embodiment 2

[0061] The combined valve 70 of the oxygen generator in this embodiment is different from the combined valve 40 of the oxygen generator 2 in the first embodiment, and the rest of the components are the same as those in the oxygen generator 2 in the first embodiment, and repeated descriptions will be omitted below.

[0062] Figure 7 It is a structural schematic diagram of the combination valve of the second embodiment of the present invention.

[0063] Such as Figure 7 As shown, the combined valve 70 includes a control gear 71 , a first valve 72 and a second valve 73 . The first valve 72 includes a first valve core 722 and a first valve body 723 (see Figure 8 to Figure 9 ). The second valve 73 includes a second valve core 732 and a second valve body 733 (see Figure 8 to Figure 9 ). The first valve core 722 is provided with a first driven gear 721, and the second valve 72 is provided with a second driven gear 731. The control gear 71 meshes with the first driven gear 72...

Abstract

The oxygen generator involved in the present invention includes: a gas source, an oxygen generator unit and a combination valve. The air source outputs air for oxygen production, and the oxygen production unit converts the air output from the air source into oxygen. The combination valve is connected to the output end of the air source and the output end of the oxygen production unit to adjust the flow rate of the output air and oxygen . Wherein, the combined valve includes at least a first valve, a second valve, and a control unit for controlling the first valve and the second valve, the first valve is connected to the output end of the oxygen generating unit, and the second valve is connected to the output end of the gas source, The control unit controls the opening and closing states of the first valve and the second valve to adjust the flow rate of oxygen passing through the first valve and the flow rate of air passing through the second valve. The number of parts of the oxygen generator of the invention is reduced, the structure is simplified, the cost is reduced, and the stability of the device is improved.

Description

technical field [0001] The invention relates to the field of oxygen generators. Background technique [0002] Oxygen concentrators are used for oxygen supplementation and oxygen inhalation in leisure home or medical fields. The oxygen generator draws air into the compressor through the intake pipe, and then produces compressed air through the compressor, and then produces high-concentration oxygen through molecular sieves. [0003] figure 1 It is a structural schematic diagram of an existing oxygen generator. [0004] Such as figure 1 As shown, the existing oxygen generator 100 generally includes a gas source 110 , an oxygen generator unit 120 , an atomization unit 130 and a solenoid valve 160 . The air source 110 sends the compressed air to the oxygen generating unit 120 and the atomizing unit 130 through the solenoid valve 160 , the oxygen generating unit 120 generates oxygen from the compressed air, and the atomizing unit 130 uses the compressed air to generate atomiz...
