DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Example

[0030] like Figure 1-4 As shown, the utility model provides a technical solution: a portable air inlet cover structure, including a side air inlet cover 100 with a plurality of filter holes opened inside, the filter holes can prevent external dust and impurities from entering the oxygen concentrator, the two sides of the bottom of the side air inlet cover 100 are symmetrically fixedly connected with lower clamping blocks 101, the top of the side air inlet cover 100 is fixedly connected with a reserved plate 205, the reserved plate 205 is provided with an empty slot inside, and an air inlet cover toggle member 200 adapted thereto is slidably connected in the empty slot of the reserved plate 205, and the top of the air inlet cover toggle member 200 is fixedly connected with a reserved plate 205, and an empty slot of the reserved plate 205 is provided with an air inlet cover toggle member 200 adapted thereto. One end of the part is fixedly connected with a pressure plate 201, and the setting of the pressure plate 201 can be convenient for users to operate, thereby driving the air inlet cover toggle member 200 to move. The two sides of the top of the air inlet cover toggle member 200 are symmetrically fixedly connected with upper clamping blocks 202, and the bottom of the air inlet cover toggle member 200 is provided with a movable component. The movable component is provided to facilitate the movement of the pressure plate 201, thereby realizing quick disassembly, and the side air inlet cover 100 can be deformed without applying pressure. At the same time, the side air inlet cover 100 can be constructed of a harder plastic material, thereby improving its protection capability.

[0031] As an implementation method in this embodiment, Figure 1-3As shown, in order to facilitate the user's operation and the removal and installation of the side air inlet cover 100, a movable component is provided, including an elastic skeleton 204 arranged at the bottom of the air inlet cover toggle member 200, the telescopic end at the top of the elastic skeleton 204 is fixedly connected to the bottom of the air inlet cover toggle member 200, the telescopic end at the bottom of the elastic skeleton 204 is fixedly connected to the inner wall of the empty groove of the reserved plate 205, the elastic skeleton 204 is constructed of rubber material, and the elastic skeleton 204 is constructed in a diamond shape.

[0032] Specifically, the pressure plate 201 can be pressed to drive the air inlet cover toggle member 200 to move, thereby compressing the elastic skeleton 204 to deform it and drive the upper clamping block 202 to disengage from the oxygen generator slot, thereby achieving disassembly. The elastic skeleton 204 can be provided to achieve the lifting and lowering of the air inlet cover toggle member 200, thereby achieving disassembly without applying force to deform the side air inlet cover 100, thereby improving the overall hardness of the side air inlet cover 100 and improving the protection capability.

[0033] Furthermore, in order to improve the stability of the movement of the air inlet cover toggle member 200, a limiting groove 206 is opened on one side of the reserved plate 205, and one side of the air inlet cover toggle member 200 is fixedly connected to the limiting block 203, the limiting block 203 is placed in the limiting groove 206, and the top of the limiting block 203 is in conflict with the top of the limiting groove 206, wherein the limiting block 203 is constructed of rubber material, and the bottom of the limiting block 203 is constructed as an inclined surface. By setting the limiting block 203 and the limiting groove 206 to cooperate with each other, the lifting and lowering range of the air inlet cover toggle member 200 can be limited, thereby preventing the air inlet cover toggle member 200 from detaching from the reserved plate 205, and thus improving the fault tolerance of the overall structure.

[0034] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, in order to improve the cleaning efficiency of the side air inlet cover 100 after disassembly and reduce the intervention of external tools, a rubber plate 301 is provided at one end of the side air inlet cover 100, and a plurality of brushes are fixedly connected to the end of the rubber plate 301 close to the side air inlet cover 100, and sliders 302 are fixedly connected to both sides of one end of the rubber plate 301, and guide grooves 300 for sliding connection of the sliders 302 are respectively provided on both sides of one end of the side air inlet cover 100. By providing the rubber plate 301 and the brush, the filter holes of the side air inlet cover 100 can be cleaned, thereby improving convenience, and the mutual cooperation of the guide groove 300 and the slider 302 can facilitate the guidance of the rubber plate 301, thereby facilitating user operation and improving cleaning efficiency.

[0035] In summary, by providing the cooperation between the air inlet cover toggle member 200 and the reserved plate 205, the problem of the side air inlet cover 100 being disassembled due to deformation under force in the prior art can be solved, so that the side air inlet cover 100 has a relatively stable hardness and improved protection capability. At the same time, the cooperation between the movable component and the air inlet cover toggle member 200 can be provided for user operation in a relatively limited space, thereby improving flexibility. By providing the rubber plate 301, it is convenient for the user to disassemble the side air inlet cover 100 for quick cleaning, thereby improving efficiency. By providing the cooperation between the slider 302 and the guide groove 300, the convenience of operation can be improved.

[0036] Working principle: When the side air inlet cover 100 needs to be disassembled, the pressure plate 201 can be pressed to drive the air inlet cover toggle member 200 to move downward, thereby applying a downward force to the top of the elastic frame 204. At this time, the elastic frame 204 will be contracted by the force, so that the air inlet cover toggle member 200 moves downward as a whole, so that the upper clamping block 202 moves downward away from the clamping slot of the oxygen concentrator. At this time, the pressure plate 201 can be pulled to tilt the side air inlet cover 100 and then pulled out to remove the side air inlet cover 100. When the side air inlet cover 100 is taken out and cleaned, it can be removed by Pull the rubber plate 301 to make the slider 302 slide back and forth in the guide groove 300 so as to clean the filter holes on the side air inlet cover 100 without the assistance of external tools. When the side air inlet cover 100 needs to be reinstalled, the side air inlet cover 100 can be tilted first so that the lower clamping block 101 is first inserted into the clamping slot in the oxygen concentrator, and then the pressing plate 201 is pressed and the side air inlet cover 100 is pushed close to the oxygen concentrator and then released. At this time, the pressing plate 201 is pushed by the elastic force of the elastic skeleton 204 to drive the upper clamping block 202 to move up and connect with the clamping slot of the oxygen concentrator.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
