Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve oxygen generators, in particular to a modular medical molecular sieve oxygen generation device. Background Technique

[0002] A molecular sieve oxygen generator utilizes the physical adsorption and desorption technology of molecular sieves. The adsorption tower of the oxygen generator is filled with molecular sieves. When pressurized, nitrogen in the air can be adsorbed, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification.

[0003] In the prior art, a Chinese patent with the publication number CN212315533U discloses a medical molecular sieve oxygen generation device, which adopts the scheme of "including a device body, the device body has an output port for outputting oxygen, and the output port is used to externally connect an oxygen injection device; a placement rack is fixedly connected to the outside of the device body, and the placement rack is provided with at least one placement position for placing the oxygen injection device externally connected to the output port". This scheme is mainly used to output oxygen with different concentrations. Therefore, the device body is often externally connected with an oxygen injection device, and the oxygen injection device is connected to the output port of the device body; when using the oxygen injection device, the oxygen injection device is taken out from the placement position of the device body; after using the oxygen injection device, the oxygen injection device is put back into the placement position of the device body again; in this way, the problem that the oxygen injection device is not convenient to place in the prior art is solved, and the operation of the medical molecular sieve oxygen generation device is made more convenient.

For example, in the actual use process of the oxygen generation device, after injecting oxygen into the oxygen injection device, it is necessary to wait for re-oxygen generation before using the oxygen injection device for oxygen injection. The whole process is relatively cumbersome, and for some hospitals with a large demand for oxygen, its oxygen generation efficiency is low.

An oxygen delivery hose 400 is arranged on the surface of the molecular sieve oxygen generator 300, and an oxygen injection pipe 600 for injecting oxygen into the interior of an oxygen storage bottle 500 is arranged at the end of the oxygen delivery hose 400. A controller 1000 is fixedly arranged on the front surface of the base 100 through an L-shaped mounting rod;

[0043] A rotating assembly 700, which is used to drive a plurality of molecular sieve oxygen generators 300 to rotate and switch. The rotating assembly 700 includes a circular groove opened on the upper surface of the installation disk 200, and a rotating disk 701 rotatably arranged on the inner wall of the circular groove. A plurality of molecular sieve oxygen generators 300 are fixedly arranged in a circumferential array on the upper surface of the rotating disk 701. The rotating assembly 700 further includes a stepper motor 702 fixedly arranged on the inner bottom wall of the circular groove for driving the rotating disk 701 to rotate;

[0044] A driving gear disk 703 is fixedly arranged at the output end of the stepper motor 702. A rotating shaft 704 is rotatably arranged on the inner bottom wall of the circular groove, and the top end of the rotating shaft 704 is fixedly connected to the lower surface of the rotating disk 701. A driven gear disk 705 meshing with the driving gear disk 703 is fixedly arranged on the outer surface of the rotating shaft 704, which is convenient for driving the rotating disk 701 to rotate at a reduced speed through the rotation of the stepper motor 702.

[0045] A limiting ring 706 is fixedly arranged on the lower surface of the rotating disk 701, and a plurality of rotating grooves are circumferentially arrayed on the lower surface of the limiting ring 706. A metal ball 707 rotatably connected to the inner wall of the rotating groove and rollingly connected to the inner bottom wall of the circular groove is arranged on the inner wall of the rotating groove, effectively ensuring the stability of the rotating disk 701 during rotation.

[0046] An oxygen injection assembly 900, which is used to connect the oxygen injection pipe 600 with the oxygen storage bottle 500. The oxygen injection assembly 900 includes a mounting frame 901 fixedly arranged on the side surface of the molecular sieve oxygen generator 300, and a lifting plate 902 slidably arranged inside the mounting frame 901. The oxygen injection pipe 600 is fixedly installed at the end of the lifting plate 902, and a second motor 903 for driving the lifting plate 902 to lift is arranged on the upper surface of the mounting frame 901.

[0047] The oxygen injection assembly 900 further includes a threaded column 904 rotatably arranged on the inner top wall and inner bottom wall of the mounting frame 901.

[0053] A slider 805 is slidably arranged on the inner wall of the strip-shaped groove. A threaded hole threadedly connected to the outer surface of the lead screw 804 is formed on the side surface of the slider 805. The upper surface of the slider 805 is fixedly connected to the lower surface of the sliding plate 802. Two symmetrically arranged contact switches 806 are fixedly arranged on the inner bottom wall of the strip-shaped groove. Both contact switches 806 are signal-connected to the first motor 803 through wires. When the slider 805 contacts one of the contact switches 806, the contact switch 806 automatically controls the first motor 803 to turn off, realizing precise switching and protecting the first motor 803 at the same time, avoiding the situation of the first motor 803 idling.
