When the passenger pulls down the pull switch 8, the electric explosion pressure reducing proportional valve group 7, the electronic lock bolt 5 and the onboard power source are connected, at this time, the electronic lock bolt 5 is unlocked to open the door plate 4, and then the oxygen masks 6 in the mask box 3 fall. At the same time, the electric explosion pressure reducing proportional valve group 7 blows open the exhaust nozzle at the bottle opening of the oxygen cylinder 2, and adjusts the pressure and flow of the oxygen output by the oxygen cylinder 2 according to the oxygen supply time point, to realize the supply of oxygen to the oxygen masks 6 at different flows in different time periods.

[0035] Embodiment 2:

[0036] A passenger time sequence oxygen supply device, improved on the basis of embodiment 1, as shown in Figure 6 and Figure 7 the electric explosion pressure reducing proportional valve group 7 includes an electric explosion valve 71, a pressure reducing valve 72 and a proportional valve 73, the electric explosion valve 71 is arranged corresponding to the exhaust nozzle of the oxygen cylinder 2, the outlet end of the electric explosion valve 71 is connected with the pressure reducing valve 72, and the outlet end of the pressure reducing valve 72 is connected with the proportional valve 73.

[0037] After the pull switch 8 is connected, the electric explosion valve 71, the pressure reducing valve 72 and the proportional valve 73 are all connected with the onboard power source, at this time, the electric explosion valve 71 blows open the exhaust nozzle at the bottle opening of the oxygen cylinder 2, and the oxygen output by the oxygen cylinder 2 is sequentially delivered to the oxygen masks 6 through the pressure reducing valve 72 and the proportional valve 73. The oxygen supply pressure is reduced to 0.35-0.85 Mpa through the pressure reducing valve 72, and then the oxygen supply flow is adjusted according to the oxygen supply time point through the proportional valve 73, specifically:

[0038] During the 0-150s period, the proportional valve 73 is at its maximum opening, outputting oxygen at a flow rate of not less than 3.12 L / min. During the 150-420s period, the proportional valve 73 decreases in opening, outputting oxygen at a flow rate of not less than 2.19 L / min. After 420s, the proportional valve 73 is at its minimum opening, outputting oxygen at a flow rate of not less than 1.71 L / min until the oxygen is exhausted.

[0039] Furthermore, the outlet of the proportional valve 73 is provided with an oxygen connector 74, which includes at least one diverter. Diverter connectors are provided for multiple oxygen masks 6, thereby enabling simultaneous oxygen supply to multiple oxygen masks 6.

[0040] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0041] Example 3:

[0042] A passenger sequential oxygen supply device, improved based on Embodiment 1 or 2, such as... Figures 1-4 As shown, the oxygen panel 1 is provided with a mask drop opening. One end of the door panel 4 is hinged to one side of the mask drop opening, and the other end of the door panel 4 is engaged with the other side of the mask drop opening via an electronic latch 5. A mask box 3 is installed on the top of the mask drop opening, and a mask limiting part is provided inside the mask box 3. An oxygen mask 6 is installed in the mask limiting part.

[0043] The other end of the door panel 4 is equipped with a lock. The electronic bolt 5 is normally extended and engaged with the lock to lock the door panel 4, preventing it from opening. In oxygen supply mode, the electronic bolt 5 is connected to the onboard power supply, retracts, and disengages from the lock. At this time, the door panel 4 rotates and opens under its own weight around the hinge, allowing the oxygen masks 6 to drop down for passengers to breathe oxygen.

[0044] Furthermore, the mask limiting strap is fitted snugly to one side of the oxygen mask 6, with one end connected to the electronic locking bolt 5 and the other end connected to the inside of the mask box 3. The mask limiting strap restricts the oxygen mask 6 inside the mask box 3, ensuring that the oxygen mask 6 always faces the mask drop opening, allowing it to fall smoothly through the opening when the door panel 4 is opened. After the electronic locking bolt 5 retracts, it disengages from one end of the mask limiting strap, at which point the strap no longer restricts the position of the oxygen mask 6, allowing it to fall smoothly.

[0045] The other parts of this embodiment are the same as those in Embodiment 1 or 2, so they will not be described again.

[0046] Example 4:

[0047] A passenger sequential oxygen supply device, improved based on any one of embodiments 1-3, such as... Figure 5 As shown, the electronic bolt 5 includes a bolt 51, an electromagnetic component 52, a manual component 53, and a housing. The bolt 51 is movably disposed inside the housing and is located between the oxygen panel 1 and the door panel 4. The electromagnetic component 52 and the manual component 53 are disposed on one side of the bolt 51, and both the electromagnetic component 52 and the manual component 53 can drive the bolt 51 to move relative to the door panel 4.

[0048] After the electromagnetic component 52 is connected to the onboard power supply, it generates a magnetic force to attract the bolt 51 to retract, causing the bolt 51 to disengage from the lock on the door panel 4, thereby unlocking the door panel 4. At the same time, a manual component 53 is also provided. When the electromagnetic component 52 fails, passengers can manually operate the manual component 53 to retract the bolt 51, thereby manually opening the door panel 4.

[0049] Furthermore, the electromagnetic component 52 includes a housing, a spring 521, an electromagnet 522, and a magnetic plate 523. A latch 51 is slidably disposed inside the housing, and the spring 521 is sleeved on the outside of the latch 51. The end of the latch 51 near the door panel 4 is connected to the door panel 4, and the end of the latch 51 away from the door panel 4 is provided with a magnetic plate 523. An electromagnet 522 is disposed on one side of the magnetic plate 523. The electromagnet 522 is connected to the onboard power supply via a pull-cord switch 8. A sliding cavity is provided inside the housing, and the latch 51 is slidably disposed inside the sliding cavity. One end of the latch 51 is inserted into the lock slot on the door panel 4, and the other end of the latch 51 is connected to the sliding cavity with the spring 521. When the electromagnet 522 is disconnected, the spring force of the spring 521 ensures that the latch 51 is securely inserted into the lock slot, keeping the door panel 4 closed. After the electromagnet 522 is connected to the onboard power supply, the electromagnet 522 generates the same magnetism as the magnetic sheet 523, so as to repel the magnetic sheet 523. Then, the magnetic sheet 523 drives the latch 51 to overcome the elastic force of the spring 521 and move away from the door panel 4. Finally, the latch 51 is disengaged from the lock, and the door panel 4 is unlocked.

[0050] Furthermore, the manual component 53 includes a rocker arm 531, which is rotatably mounted on one side of the latch 51. The rocker arm 531 has a latch that engages with one end of the latch 51. The middle part of the rocker arm 531 is rotatably connected to the housing via a rotating pin. One end of the rocker arm 531 extends outside the housing for manual operation by the passenger, while the other end of the rocker arm 531 has a latch with a diameter larger than that of the latch 51. When the passenger manually rotates the rocker arm 531, the latch engages with the side wall of the latch 51, causing the latch 51 to move until it disengages from the lock on the door panel 4 and unlocks.

[0051] The other parts of this embodiment are the same as any one of embodiments 1-3, so they will not be described again.

[0052] Example 5:

[0053] A passenger sequential oxygen supply device, improved based on any one of embodiments 1-4, such as... Figure 8 As shown, the oxygen cylinder 2 is also equipped with an overpressure relief valve 9. The pressure-receiving end of the overpressure relief valve 9 is connected to the internal environment of the oxygen cylinder 2, and the pressure-relieving end of the overpressure relief valve 9 is threadedly fitted with a pressure-relieving nut. A rupture disc is installed between the pressure-receiving end and the pressure-relieving end. When the pressure inside the oxygen cylinder 2 exceeds the safety threshold, the rupture disc breaks under pressure, connecting the pressure-receiving end and the pressure-relieving end, allowing the oxygen inside the oxygen cylinder 2 to be released to the external environment, thereby safely relieving the pressure of the oxygen cylinder 2. At the same time, by rotating the pressure-relieving nut, the opening degree of the pressure-relieving end can be adjusted, thereby adjusting the pressure relief speed of the oxygen cylinder 2. After the pressure is relieved to a safe pressure, the pressure-relieving nut is tightened to close the pressure-relieving end, preventing the oxygen inside the oxygen cylinder 2 from being completely lost.

[0054] The other parts of this embodiment are the same as any one of embodiments 1-4, so they will not be described again.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
