Description

A kind of oxygenerator filter device

Technical field

The utility model is related to a kind of the field of medical instrument technology, more particularly, to a kind of oxygenerator filter device.

Background technology

With the continuous improvement of living standards, Domestic oxygen erator (Oxygen concentrator) is increasingly made extensively With, be used to manufacture oxygen, be suitable for oxygen therapy and oxygen health care crowd.

Domestic oxygen erator manufactures oxygen using molecular sieve physical adsorption techniques, by loading molecule in Domestic oxygen erator Sieve, can be by the nitrogen adsorption in air in pressurization, and remaining unabsorbed oxygen is collected, by purified treatment Become the oxygen of high-purity afterwards.

Normally only air is simply filtered during making oxygen in traditional Domestic oxygen erator, filters out sky Larger impurity in gas, can not filter tiny impurity, influence the adsorption effect of molecular sieve.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art, provide a kind of oxygenerator filter device, can Air is fully filtered, the adsorption efficiency of analysis sieve is improved.

To achieve the above object, the utility model proposes following technical solutions：A kind of oxygenerator filter device, including shell Body, the shell include the first end face and second end face being oppositely arranged, and the first end face is equipped with plural air admission hole, described Second end face is equipped with gas outlet, and the first filter layer, the second filter layer and the third being cascading are equipped in the shell Filter layer, for first filter layer between air admission hole and the second filter layer, the third filter layer is located at the second filter layer Between gas outlet.

Preferably, first filter layer is wool carpet veneer, and the second filter layer is spongy layer, and third filter layer is wool felt Layer.

Preferably, first filter layer is spongy layer, and the second filter layer is wool carpet veneer, and third filter layer is sponge Layer.

Preferably, the shell includes the first shell and second shell being mutually flexibly connected, and the gas outlet is set to first On shell, the air admission hole is set in second shell.

Preferably, the first shell is connected using thread connecting mode with second shell or is connected using snap fit It connects.

Preferably, the first shell be cylindrical housings, the second shell be cylindrical housings, and second shell with The end that first shell is in contact is set on the outer wall of first shell.

The utility model has the beneficial effects that：

Compared with prior art, oxygenerator filter device described in the utility model, by the way that the first filter layer, the is arranged Two filter layers and third filter layer filter out the fine impurities in air, improve air degree of purity, and then improve the absorption of molecular sieve Efficiency；In addition, oxygenerator also has the advantages that simple in structure, low manufacture cost with filter device.

Specific implementation mode

Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete Description.

In conjunction with shown in Fig. 1 and Fig. 2, a kind of revealed oxygenerator filtering of the utility model, including shell 1, shell 1 wrap Include the first end face 11 being oppositely arranged and second end face 12, first end face 11 is equipped with plural air admission hole 111, in second end face 12 Equipped with a gas outlet 121.For the better fine impurities crossed in air filtering, first to be cascading is equipped in shell 1 Filter layer 2, the second filter layer 3 and third filter layer 4, the first filter layer 2 are located between air admission hole 111 and the second filter layer 3, the For three filter layers 4 between the second filter layer 3 and gas outlet 121, the air entered from air admission hole 111 passes through the first filtering successively The 2, second filter layer 3 of layer and third filter layer 4, to filter out fine impurities in air.

In the present embodiment, the first filter layer 2 is wool carpet veneer, and the second filter layer 3 is spongy layer, and third filter layer 4 is sheep Felt layers；Or first filter layer 2 be spongy layer, the second filter layer 3 be wool carpet veneer, 4 spongy layer of third filter layer.Implement When, with the first filter layer 2 for wool carpet veneer, the second filter layer 3 is spongy layer, and third filter layer 4 is that wool carpet veneer is best.

As shown in Figure 1, shell 1 includes first shell 13 and second shell 14.Wherein, gas outlet 121 is set to first shell On 13, air admission hole 111 is set in second shell 14.First shell 13 is flexibly connected with 14 the two of second shell, is connected using screw thread The mode of connecing is connected or is connected using snap fit, easy to disassemble, is conducive to the periodic replacement of filter layer.

Preferably, first shell 13 is cylindrical housings, and second shell 14 is similarly cylindrical housings, second shell 14 Internal diameter size is more than the outer diameter of first shell 13 so that the end that second shell 14 is in contact with first shell 13 can cover It is located on the outer wall of first shell 13.

At work, air enters from air admission hole 111, first passes around the first filter layer 2 and carries out primary filter, filters out part Secondly impurity carries out secondary filter by the second filter layer 3, and can filter out partial impurities, finally pass through third filter layer 4, then It is secondary to filter out impurity.After filtering three times, clean air can be made to enter in molecular sieve, improve its adsorption efficiency.

The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used Teaching and announcement that can be based on the utility model and make various replacements and modification without departing substantially from the spirit of the present invention, therefore, this Utility model protection range should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model And modification, and covered by present patent application claim.
