Detailed implementation mode

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] Please refer to Figures 1 to 9, the present invention provides an oxygen supply device for installation on furniture, comprising a cabinet 1, two oxygen cylinders, an automatic switching device 2, a pressure reducing and stabilizing device 3, a pipeline 4 and an oxygen outlet 5. The oxygen supply device for installation on furniture further comprises a plurality of universal wheels 6, two movable flaps 7, a door panel 8 and a drawer 9. The cabinet 1 has two storage grooves 10. The oxygen cylinder comprises a cylinder body 11, a valve 12 and a humidifying cup 13. The oxygen supply device for installation on furniture further comprises two docking units. The docking unit comprises an electric push rod 14, a frame 15, a telescopic hose 16, a sealing sleeve 17 and a docking pipe 18. The oxygen supply device for installation on furniture further comprises a pushing unit. The pushing unit comprises a chute 19, a slider 20, a moving block 21, a screw machine 22, a pushing box 23 and a plurality of clamping mechanisms. The pushing box 23 has a placement groove 24. The clamping mechanism comprises a telescopic rod 25, a first spring 26 and a clamping block 27. The clamping block 27 has a first inclined surface 28. The oxygen supply device for installation on furniture further comprises a plurality of limiting units. The limiting unit comprises a limiting block 29, a connecting plate 30, a plurality of second springs 31 and a button 32. The cabinet 1 further has a limiting groove 33. The door panel 8 has a groove 34. The limiting block 29 has a second inclined surface 35.

[0035] Among them, the two oxygen cylinders are sequentially placed inside the cabinet 1. The oxygen outlets 5 are symmetrically arranged on the cabinet 1. One end of the pipeline 4 is respectively communicated with the corresponding oxygen outlet 5. The other ends of the pipeline 4 are both connected to the pressure reducing and stabilizing device 3. The pressure reducing and stabilizing device 3 is connected to the automatic switching device 2. Both ends of the automatic switching device 2 are respectively connected to the corresponding oxygen cylinder. Place the oxygen cylinder inside the cabinet 1; when oxygen is discharged from the oxygen cylinder, the output of oxygen is kept stable by the pressure reducing and stabilizing device 3; oxygen reaches the oxygen outlet 5 through the pipeline 4 for oxygen supply; when the oxygen in the oxygen cylinder is exhausted, the automatic switching device 2 switches to another oxygen cylinder for oxygen supply.

[0036] Secondly, the plurality of universal wheels 6 are sequentially arranged below the cabinet 1. The two movable flaps 7 are both rotatably connected to the cabinet 1 and are located on one side of the corresponding oxygen outlet 5. The door panel 8 is rotatably connected to the cabinet 1 and is located on one side of the cabinet 1. The drawer 9 is arranged on one side of the door panel 8. The two storage grooves 10 are respectively arranged above and below the drawer 9. The position of the furniture on which the oxygen supply device is installed can be freely adjusted through the universal wheels 6. When oxygen supply is not required, rotate and close the movable flap 7 to protect the oxygen outlet 5 from being contaminated with dust. When the oxygen cylinder needs to be replaced, open the door panel 8 for installation and maintenance operations. The drawer 9 and the upper and lower storage grooves 10 can store personal items of users.

[0037] Meanwhile, the bottle body 11 is placed inside the cabinet body 1. The bottle body is connected to the automatic switching device through a connecting hose. When the pressure of one of the gas cylinders is lower than the set pressure value (0.5 mpa), the switching device automatically switches to the other gas cylinder. At this time, we can replace the used gas cylinder. By repeating this process, uninterrupted oxygen supply can be achieved. The humidifying cup and the flow regulating device are inserted into the oxygen outlet to achieve humidification and flow control of oxygen.

[0038] In addition, the two docking units are symmetrically arranged inside the cabinet body 1; the electric push rod 14 is arranged on the inner top wall of the cabinet body 1. The output end of the electric push rod 14 is fixedly connected to the frame 15. The two ends of the telescopic hose 16 are respectively fixedly connected to the automatic switching device 2 and the frame 15. The sealing sleeve 17 is arranged inside the frame 15. The sealing sleeve 17 is communicated with the telescopic hose 16. One end of the docking pipe 18 is communicated with the humidifying cup 13, and the other end of the docking pipe 18 is located below the sealing sleeve 17. Before automatically docking the oxygen cylinder, first close the valve 12. At this time, start the electric push rod 14 to drive the frame 15 to move downward, so that the telescopic hose 16 extends out, and then drive the sealing sleeve 17 to move downward and sleeved outside the docking pipe 18 to complete the docking of the oxygen cylinder and the automatic switching device 2. At this time, the valve 12 can be opened for oxygen supply; at the same time, the electric push rod 14 has a self-locking function and is self-locked after docking to prevent the sealing sleeve 17 and the docking pipe 18 from separating. When the pressure of the bottle body 11 is lower than 0.5 MPA, close the valve 12 of the bottle body 11, and then open the other valve 12. The oxygen of the other oxygen cylinder continues to supply oxygen through the automatic switching device 2. The automatic switching device 2 is a housing that provides a transfer for the oxygen of the two oxygen cylinders and reaches the decompression and voltage stabilization device 3 through this housing and then continues to output; thus, automatic switching of oxygen can be carried out; the valve 12 is a pressure detection electronic valve and has the function of monitoring the pressure of the bottle body 11.

[0039] Then, the pushing unit is arranged inside the cabinet body 1; the pushing box 23 has a placement groove 24, the sliding groove 19 is arranged on the inner side wall of the cabinet body 1, the sliding block 20 is fixedly connected to the sliding groove 19, the sliding block 20 is fixedly connected to the pushing box 23 and is located on one side of the pushing box 23, the moving block 21 is arranged above the pushing box 23, the screw machine 22 is arranged inside the cabinet body 1, the moving block 21 is adapted to the output end of the screw machine 22, and a plurality of the clamping mechanisms are all arranged inside the pushing box 23 and are distributed around the corresponding outer part of the bottle body 11. When the screw machine 22 is started, a threaded hole is arranged on the moving block 21, thereby driving the moving block 21 to move. At this time, the pushing box 23 is driven to slide inside the cabinet body 1, so that the sliding block 20 slides in the sliding groove 19 to maintain the moving stability. Finally, the pushing box 23 is stably moved out of the inside of the cabinet body 1. At this time, the oxygen cylinder can be disassembled and installed. After installation, the oxygen cylinder can be clamped by the clamping mechanism. At the same time, the bottle body 11 is placed inside the placement groove 24, thereby preventing the oxygen cylinder inside from shaking when the cabinet body 1 moves.

[0040] Again, the clamping block 27 has a first inclined surface 28. The two ends of the telescopic rod 25 are respectively fixedly connected to the inner wall of the pushing box 23 and the clamping block 27. The two ends of the first spring 26 are respectively movably connected to the inner wall of the pushing box 23 and the clamping block 27. The first spring 26 is sleeved outside the telescopic rod 25. When the bottle body 11 is lowered and placed, first, the lower end of the bottle body 11 contacts the first inclined surface 28 of the clamping block 27, thereby pushing the clamping block 27 to contract. Then, after the bottle body 11 is placed well, a plurality of the clamping blocks 27 are distributed around the outer part of the bottle body 11. At this time, the first spring 26 rebounds, driving the clamping block 27 to clamp the bottle body 11 to achieve limit protection. At the same time, the telescopic rod 25 extends and contracts along with the clamping block 27 to maintain the stability of the clamping block 27 and prevent the clamping block 27 from shaking.

[0041] Moreover, multiple said limiting units are respectively arranged on the two said movable flaps 7 and the door panel 8; the cabinet body 1 further has a limiting groove 33, the door panel 8 has a groove 34, the limiting block 29 is slidably connected to the door panel 8 and is located inside the groove 34, the limiting block 29 has a second inclined surface 35, the connecting plate 30 is fixedly connected to one end of the limiting block 29 and is located inside the groove 34, and both ends of multiple said second springs 31 are movably connected to the connecting plate 30 and the inner wall of the groove 34 respectively. The button 32 penetrates through the door panel 8 and is fixedly connected to the connecting plate 30. When closing the movable flap 7 and the door panel 8, the second inclined surface 35 of the limiting block 29 contacts the cabinet body 1, and thus is pushed to contract. Then when reaching the limiting groove 33, the second spring 31 rebounds, driving the connecting plate 30 and the limiting block 29 to rebound. The limiting block 29 enters the limiting groove 33 to complete the limiting operation of the door panel 8 or the movable flap 7. When it is necessary to open, press the button 32. Through the connection of the connecting plate 30, drive the limiting block 29 to contract. After disengaging from the limiting groove 33, it can be opened.

[0042] When using an oxygen supply device for installation on furniture according to this embodiment, first, the screw machine 22 is started. There is a threaded hole provided on the moving block 21, which then drives the moving block 21 to move. At this time, it drives the pushing box 23 to slide within the cabinet body 1, and finally stably moves the pushing box 23 out of the interior of the cabinet body 1. At this time, place the oxygen cylinder in the placement groove 24 of the pushing box 23 and clamp it through the clamping mechanism; then start the electric push rod 14 to drive the frame 15 to move downward, so that the telescopic hose 16 extends, and then drives the sealing sleeve 17 to move downward and sleeved on the outside of the docking pipe 18 to complete the docking of the oxygen cylinder and the automatic switching device 2; at this time, open the valve 12. When oxygen is discharged from the oxygen cylinder, the output of oxygen is kept stable through the pressure reducing and stabilizing device 3; the oxygen reaches the oxygen outlet 5 through the pipeline 4; at the same time, press the button 32. Through the connection of the connecting plate 30, drive the limiting block 29 to contract. After disengaging from the limiting groove 33, open the movable flap 7 to supply oxygen; when the pressure of the cylinder body 11 is lower than 0.5 MPA, close the valve 12 of the cylinder body 11 in use, and then open the other valve 12. Relying on the connection of the automatic switching device 2, switch to another oxygen cylinder for oxygen supply; through the above structural settings, the oxygen supply device is installed inside the cabinet body 1, making it integrated with the furniture. It is not only convenient for installation and maintenance, but also can move the position and be placed in any area of the room, greatly improving flexibility. Moreover, when users use the furniture, they can directly supply oxygen, getting closer to the oxygen, without large-scale renovation of the room, improving the indoor aesthetics. At the same time, the oxygen outlet 5 can be connected to an oxygen inhaler or an oxygen mask, so that when users have difficulty breathing in daily life, oxygen can be supplied in time.
