Embodiment 1

[0052] Reference attached figure 1 to attach Figure 6 Embodiment 1 of the present invention proposes a filter device, which is used for air filtration of a diffuse oxygen and nitrogen separation device in a plateau environment. The filter screen 1 on the air intake side parts, the air intake side parts include an air intake cover 2 and an air intake side plate 3, the air intake side plate 3 is installed towards the air intake side of the inner cabinet 4, and the air intake cover 2 is provided with There is an air intake space 222 for inserting the external air intake joint 5, and the air intake space 222 is located above the insertion position of the external air intake joint 5;

[0053] The air intake cover 2 includes an integrally formed lower air intake frame 21 and an upper air intake frame 22; Extending to the other end, at least two positioning bosses 212 are fixed on the inner side of the first frame 211, and staggered support ribs for supporting the first frame 211...

Embodiment 2

[0060] see Figure 5 As shown, Embodiment 2 of the present invention proposes a diffused oxygen and nitrogen separation device, and the separation device uses the filter device in the above solution. The separation device also includes an inner casing 4 and an air intake joint 5 passing through the inner casing 4. The filter device is vertically fixed on the air inlet side of the inner casing 4, and is made by the cooperation of the fastener and the positioning boss 212. The air intake cover 2 and the air intake side plate 3 are fixed to the inner case 4, and the air intake joint 5 passes vertically upwards through the second frame 221 below and then enters the air intake space 222. The lower surface of the second frame 221 is in contact with the The upper surface of the inner case 4 is in close contact with each other.

[0061] One of the installation methods of the filter device in Embodiment 1 is described below:

[0062] When carrying out the installation of the filter d...

Abstract

The invention relates to a filter device and a dispersed oxygen and nitrogen separation device using the same. The filter device comprises an air inlet side part installed on the air inlet side of aninner case and a filter screen sleeving the air inlet side part; the air inlet side part comprises an air inlet cover and an air inlet side plate, wherein the air inlet cover comprises a lower air inlet rack and an upper air inlet rack which are integrally formed; a first frame is arranged on the lower air inlet rack, and positioning bosses, supporting ribs and first supporting columns are arranged on the first frame; the upper air inlet rack is provided with second frames, and an air inlet space allowing an external air inlet connector to be inserted therein is formed between the second frames. With the filter device provided by to the technical schemes of the invention adopted, the problems that a filter device in the prior art is complex in structure, complex in production and assembly,high in cost, time-consuming and labor-consuming in replacement and the like are solved. The filter device of the invention which is ingenious in structure, easy to produce, convenient to replace andcapable of saving labor. The dispersed oxygen and nitrogen separation device using the filter device is provided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a filter device and a diffuse oxygen-nitrogen separation device using the filter device. Background technique [0002] The oxygen and nitrogen separation device is a device that separates nitrogen and oxygen in the air. It is divided into a nitrogen generator and an oxygen generator. The oxygen generator is a device that can provide high-concentration oxygen for human breathing. The oxygen generator supplies Oxygen therapy for people suffering from respiratory system diseases, cardiovascular system diseases, cerebrovascular diseases, altitude sickness and altitude sickness, for middle-aged and elderly frail people, students and pregnant women who overuse their brains, and people who work and live in hypoxic environments For people, inhaling more pure oxygen can promote blood circulation, refresh the mind, eliminate fatigue, and effectively improve work efficiency. Therefo...
