[0002] Molecular sieve oxygen generator refers to a new type of equipment that extracts oxygen from the air based on pressure swing adsorption (PSA) technology. It uses molecular sieve physical adsorption and desorption technology to fill the molecular sieve in the oxygen generator. It can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The specific working process is that the compressed air is purified by the air purification dryer and enters the adsorption tower through the switching valve. In the adsorption tower, nitrogen is adsorbed by the molecular sieve, and the oxygen is accumulated at the top of the adsorption tower and enters the oxygen storage tank. It is then filtered through the odor removal, dust removal filter and sterilization filter to obtain qualified medical oxygen.

[0003] The shell of a general small medical molecular sieve oxygen generator is usually fixed with screws or snap-fit ​​connections. Screw fixing makes it inconvenient to disassemble the shell, while snap-fit ​​connection leads to poor snap-fitting firmness of the shell, and the decorative panel on the shell surface cannot be removed, resulting in a relatively simple style of the decorative panel. In response to the above situation, we have introduced a shell structure with a replaceable decorative panel. Utility Model Content

[0030] like Figure 1-10 As shown, the front trim panel 8, the front housing 3, the rear housing 4 and the rear trim panel 13 are penetrated by a card strip 9, the outer surface of the front trim panel 8 is provided with a groove, the connecting head 10 is located in the groove, the other end of the card strip 9 is fixedly provided with a card head 12, the outer surface of the rear trim panel 13 is provided with a slide groove 14, the slide groove 14 is slidably connected with a shift block 15, the side of the shift block 15 close to the slide groove 14 is fixedly provided with a slider 16, and the side of the shift block 15 is provided with a third card slot 17 matching the card head 12, and the card strip 9 can be moved from the front trim panel 8 and penetrate through the outer surface of the rear trim 13, while the connector 10 at one end of the card strip 9 will be located in the groove and cannot be further inserted inward, and the shift block 15 at the slide groove 14 on the outer surface of the rear trim 13 can slide along the slide groove 14 through the slider 16, so that the third slot 17 on one side of the shift block 15 is engaged with the card head 12 at the other end of the card strip 9, thereby limiting the card strip 9 so that it cannot be pulled out of the shell, effectively improving the structural stability of the shell after assembly.

[0031] A connector 10 is sleeved on the outer wall of one end of the clamping strip 9, and a spring 11 is fixedly connected between the clamping strip 9 and the connector 10. By applying pressure to the clamping strip 9, the clamping strip 9 can be moved toward the shift block 15 due to the contraction of the spring 11, so that the clamping head 12 at the other end of the clamping strip 9 can be connected with the third clamping groove 17 on one side of the shift block 15. After the connection and engagement, the connector 11 can use the elastic force of the spring 11 to tightly clamp the front trim panel 8, the front housing 3, the rear housing 4 and the rear trim panel 13, making them less likely to separate, thereby further improving the structural stability of the outer shell.

After the shift block 15 is engaged with the card strip 9, the limiting marble 19 on the surface of the connecting block 18 on one side of the shift block 15 will pop outward at the limiting groove 20, thereby limiting and fixing the shift block 15 to prevent it from moving and causing the shift block 15 to separate from the card strip 9. The limiting marble 19 is connected through a spring inside the connecting block 18. When the connecting block 18 moves to contact the inner wall of the slide groove 14, the limiting marble 19 will be compressed and contracted inward by the spring, and pop outward at the limiting groove 20.

[0033] The shift block 15, the slider 16 and the connecting block 18 are integrally formed by injection molding, which can effectively improve the structural strength of the shift block 15 and ensure that it is not easily damaged during use.

[0034] A cup groove 21 is provided on the surface of the rear decorative plate 13 for placing a humidification cup, so as to improve the functionality of the housing.

[0035] Working principle: first, the front shell 3 and the rear shell 4 can be clamped with the first clamping groove 2 on the outer wall of the base 1 through the second clamping block 6 at the bottom, and the front shell 3 and the rear shell 4 can be clamped with each other through the first clamping block 5 and the second clamping groove, thereby completing the preliminary assembly of the shell, and the front decorative panel 8 and the rear decorative panel 13 can be similarly clamped with the clamping grooves on the surfaces of the front shell 3 and the rear shell 4 through the clamping blocks on the edges, thereby completing the installation of the decorative panels, and subsequently the decorative panels can be removed and replaced with decorative panels of different colors for decoration to improve the presentation effect of the shell, and then the set card strip 9 can be inserted from the groove of the front decorative panel 8 and pass through the outer surface of the rear decorative panel 13, and the connecting head 10 at one end of the card strip 9 will be located in the groove and cannot be inserted further inward, and then pressure is applied to the card strip 9, so that the card strip 9 moves toward the shift block 15 through the contraction of the spring 11, so that the card strip 9 The card head 12 at the other end of the 9 is on the same horizontal line with the third card slot 17 on one side of the shift block 15, and then the shift block 15 at the slide slot 14 on the outer surface of the rear decorative plate 13 can slide along the slide slot 14 through the slider 16, so that the third card slot 17 on one side of the shift block 15 is engaged with the card head 12 at the other end of the card strip 9, and then the card strip 9 is limited so that it cannot be pulled out of the shell. Finally, after the shift block 15 is engaged with the card strip 9, the limiting marble 19 on the surface of the connecting block 18 on one side of the shift block 15 will pop outward at the limiting groove 20, thereby limiting and fixing the shift block 15 to prevent it from moving and causing the shift block 15 to separate from the card strip 9. After docking and engaging, the connecting head 11 can use the elastic force of the spring 11 to tightly hold the front decorative plate 8, the front shell 3, the rear shell 4 and the rear decorative plate 13, so that they are not easy to separate, thereby further improving the structural stability of the shell.
