[0037] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0038] On the one hand, if Figure 1 and Figure 2 As shown, an external oxygen generator in one embodiment of the utility model includes:

[0039] The oxygen production box 1 has a connection seat 11 at the bottom, and a connection long groove is provided on the connection seat 11;

[0040] The mounting bracket 2 comprises a fixed vertical beam 21 and a mounting horizontal beam 22 arranged perpendicular to the fixed vertical beam 21, wherein the mounting horizontal beam 22 is provided with a mounting hole adapted to the connecting long groove;

[0041] The fixing rod 3 has one end connected to the fixing vertical beam 21 and the other end connected to the oxygen production box 1 .

[0042] The above-mentioned oxygen generator is connected to the long groove and the mounting hole by a bolt assembly, so that the oxygen generator box 1 is fixedly connected to the mounting bracket 2; at the same time, the fixing rod 3 is used to connect the fixed vertical beam 21 to the oxygen generator box 1 to form a quadrilateral connection structure, thereby strengthening the connection strength between the oxygen generator box 1 and the mounting bracket 2 and enhancing the safety of the use of the oxygen generator box 1.

[0043] In one embodiment, the mounting bracket 2 further includes a limiting unit 4 disposed on the mounting crossbeam 22; the limiting unit 4 includes a first crossbeam 41 and a second crossbeam 42 disposed in parallel, and the oxygen production box 1 is disposed between the first crossbeam 41 and the second crossbeam 42. In this way, a limiting space is formed by the first crossbeam 41 and the second crossbeam 42 to prevent the oxygen production box 1 from moving along the beam length direction of the mounting crossbeam 22 and detaching from the mounting bracket 2, thereby enhancing the safety of the oxygen production box 1.

[0044] In one embodiment, the limiting unit 4 includes an elastic member 43 provided on the first cross beam 41, and a pressing member 44 provided on the second cross beam 42; by adjusting the pressing member 44, the oxygen production box 1 is pushed to press the elastic member 43. In this way, by adjusting the pressing member 44, the oxygen production box 1 is pushed to press the elastic member 43, thereby fixing the position of the oxygen production box 1.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the elastic member 43 includes a first bolt 431, a rubber block 432 disposed at the threaded end of the first bolt 431, and a spring member 433 sleeved on the first bolt 431; the pressing member 44 is a second bolt threadedly connected to the second crossbeam 42.

In this way, the connecting holes of the two inclined surfaces of the ∧-shaped bending plate are used to connect the gas outlet chamber 102 with the oxygen production chamber 101, thereby preventing raindrops from entering the gas outlet chamber 102 from the gas outlet hole, ensuring that the oxygen production component 6 in the oxygen production box 1 can still work normally under harsh environments.

[0049] In one embodiment, an air outlet partition 13 is provided on the top of the oxygen production box 1, and the air outlet hole is arranged on the air outlet partition 13 and the air outlet direction is obliquely downward. In this way, the air outlet partition 13 is used to set the air outlet direction of the air outlet hole obliquely downward, ensuring that the oxygen production component 6 in the oxygen production box 1 can still work normally in a harsh environment.

[0050] On the other hand, Figure 1 and Figure 4As shown, an oxygen production device in an embodiment of the utility model includes an oxygen production external machine 5 and an oxygen production component 6; the oxygen production component 6 is arranged inside the oxygen production box 1. Specifically, the oxygen production component 6 uses air separation technology to compress the air at a high density, and then uses the difference in condensation points of various components in the air to separate gas and liquid at a certain temperature, and then performs distillation to separate oxygen.

[0051] In one embodiment, the oxygen generator 5 includes an oxygen generator outer shell 51 and an oxygen generator inner shell 52 disposed inside the oxygen generator outer shell 51; the oxygen generator component 6 includes an oxygen generator host 61 disposed inside the oxygen generator inner shell 52, and an oxygen generator filter 62 disposed outside the oxygen generator inner shell 52.
