Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical oxygen concentrator capable of reducing the operating noise of a compressor. Background Art

[0002] A medical oxygen concentrator is a medical device that extracts oxygen from the air. It mainly uses pressure swing adsorption technology. This device separates nitrogen from the air and collects oxygen through the physical adsorption and desorption technology of molecular sieves. The molecular sieve adsorbs nitrogen under pressurized conditions and releases nitrogen when depressurized, thereby achieving periodic oxygen production. Most of the current medical oxygen concentrators do not have protective structures. When not in use, medical oxygen concentrators are prone to adsorbing dust and pollutants in the air, which may affect the performance of the equipment and the purity of oxygen. They are also easily damaged by collisions or falls during transportation or storage. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a medical oxygen concentrator capable of reducing the operating noise of a compressor comprises a body 1, an outer surface of the body 1 is provided with a locking structure 2, the outer surface of the locking structure 2 is rotatably connected to a protective shell 1 3, the outer surface of the locking structure 2 is rotatably connected to a protective shell 2 4, a connecting plate 2 6 is fixedly connected above the protective shell 1 3, a connecting plate 1 5 is fixedly connected above the protective shell 2 4, a clamping structure 7 is slidably connected inside the connecting plate 2 6, the clamping structure 7 is connected to the connecting plate 1 5, a push plate 8 is connected above the clamping structure 7, the clamping structure 7 comprises a support rod 701, a movable plate 702 and an inclined plate 2 704, an inclined plate 1 703 is fixedly connected to the left side above the movable plate 702, a fixed disk 705 is fixedly connected to the top of the support rod 701, and a spring 706 is connected to the outer surface of the support rod 701.

[0021] like Figure 1 and Figure 3 As shown, the push plate 8 is slidably connected in the connecting plate 2 6, a display screen 9 is provided above the body 1, a button 10 is provided on the front of the body 1, the movable plate 702 is slidably connected in the connecting plate 2 6, the movable plate 702 is clamped in the connecting plate 1 5, the support rod 701 is fixedly connected to the top of the connecting plate 1 5, the inclined plate 2 704 is slidably connected to the outside of the support rod 701, the inclined plate 2 704 is connected to the fixed plate 705 through the spring 706, the inclined plate 1 703 and the inclined plate 2 704 overlap, and the push plate 8 is fixedly connected to the top of the movable plate 702.

[0022] By setting the spring 706, the push plate 8 applies a thrust to the movable plate 702, and the movable plate 702 is stuck in the connecting plate 1 5 when it moves, and the inclined plate 1 703 above the movable plate 702 contacts the inclined plate 2 704. When the inclined plate 2 704 slides on the surface of the support rod 701, the spring 706 is driven to deform, so that the spring 706 plays a certain supporting role in the movement of the inclined plate 2 704. When the inclined plate 2 704 loses resistance, it is reset by the inclined plate 2 704 to prevent the inclined plate 2 704 from falling off when it moves.

[0023] like Figure 4 As shown, the locking structure 2 includes a fixing rod 1 201 and a fixing rod 2 202. The fixing rod 1 201 is fixedly connected to the front of the body 1, and the fixing rod 2 202 is fixedly connected to the front of the body 1. The fixing rod 1 201 is externally rotatably connected to a gear 1 203, and the fixing rod 2 202 is externally rotatably connected to a gear 2 204. The gear 1 203 is engaged with the gear 2 204. One side of the gear 1 203 is connected to the protective shell 2 4, and one side of the gear 2 204 is connected to the protective shell 1 3. A threaded groove 206 is provided on the outside of the fixing rod 2 202, and a nut 205 is externally threadedly connected to the threaded groove 206. The nut 205 overlaps the gear 2 204.

[0024] By setting up the locking structure 2, a rotational force is applied to the protective shell 1 3. Since the gear 2 204 is engaged with the gear 1 203, the protective shell 1 3 and the protective shell 2 4 can realize the function of relative rotation. When the protective shell 1 3 and the protective shell 2 4 are rotated to the appropriate position, the nut 205 and the thread groove 206 are driven to connect, and the nut 205 will contact the gear 2 204, so as to locate the position of the protective shell 1 3 and the protective shell 2 4 after flipping, and lock the flipped position of the protective shell 1 3 and the protective shell 2 4. After flipping, the protective shell 1 3 and the protective shell 2 4 can increase the contact area between the body 1 and the ground, thereby ensuring the stability of the body 1 when in use.

[0025] The utility model provides a medical oxygen concentrator that can reduce the operating noise of the compressor. The specific working principle is as follows:

[0026] When the medical oxygen concentrator is not in use, the protective shell 1 3 and the protective shell 2 4 are turned over and overlapped with each other, and the connecting plate 1 5 and the connecting plate 2 6 are on the same horizontal line. The push plate 8 applies a thrust to the movable plate 702, and the movable plate 702 is clamped in the connecting plate 1 5 when moving, and the inclined plate 1 703 above the movable plate 702 contacts the inclined plate 2 704. When the inclined plate 2 704 slides on the surface of the support rod 701, it drives the spring 706 to deform. When the movable plate 702 moves to the appropriate position, the inclined plate 1 703 is separated from the inclined plate 2 704. When the inclined plate 2 704 loses resistance, it is reset by the spring 706. After reset, the inclined plate 2 704 overlaps the inclined plate 1 703.

[0027] When the medical oxygen concentrator is in use, the protective shell 1 3 and the protective shell 2 4 are disassembled, and then a rotational force is applied to the protective shell 1 3. Since the gear 2 204 is engaged with the gear 1 203, the protective shell 1 3 and the protective shell 2 4 can realize the function of relative rotation. When the protective shell 1 3 and the protective shell 2 4 are rotated to the appropriate position, the nut 205 and the thread groove 206 are driven to connect, and the nut 205 will contact the gear 2 204, which can locate the position of the protective shell 1 3 and the protective shell 2 4 after flipping. The body 1 adopts an oil-free compressor, and a sound insulation sponge is provided inside to absorb and isolate the noise generated when the oil-free compressor is running.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
