[0024] like Figure 1-4 As shown, this embodiment includes a reaction chamber 1, wherein the upper end opening of the reaction chamber 1 is provided with:

[0025] The rotary chamber 2 is inserted into the upper port of the reaction chamber 1, and the lower end of the rotary chamber is rotated on the lower inner wall of the reaction chamber 1 through a rotating shaft;

[0026] The walls of the rotor bin 2 are provided with three bins at equal angles, and the shape of the bins matches the shape of the oxygen candles used for oxygen production;

[0027] An ignition rod 3 is screwed onto the wall of the reaction chamber 1 via a bearing. An exhaust port 4 is provided on the reaction chamber 1, and a side end of the ignition rod 3 is inserted into the exhaust port 4.

[0028] A waste door 5 is provided on the side wall of the reaction chamber 1 with a waste outlet 6. The waste door 5 is hinged to the side of the waste outlet 6 and is movable to cover the waste outlet 6.

[0029] The storage chamber 7 is placed on the wall of the reaction chamber 1 opposite to the exhaust port 4;

[0030] A support base 8, wherein the support base 8 is arranged in the storage compartment 7;

[0031] A reed 9, wherein the reed 9 is fixedly mounted on the support base 8, and the other end of the reed 9 is fixedly mounted on the inner wall of the receiving chamber 7 at the end away from the reaction chamber 1;

[0032] The connecting seat 10 is arranged in the receiving chamber 7, and the connecting seat 10 is arranged on the side of the supporting seat 8 facing the reaction chamber 1;

[0033] A connecting rod 11, wherein the connecting rod 11 is rotated on the connecting seat 10 via a rotating shaft, and the other end of the connecting rod 11 is rotated on the supporting seat 8 via a rotating shaft;

[0034] A driving gear 12, wherein the driving gear 12 is fixedly arranged at the upper end of the rotary chamber 2;

[0036] A driven gear 14 is fixedly mounted on the end of the crankshaft 13 and is meshed with the driving gear 12;

[0037] A guide rod 15, wherein the guide rod 15 is rotatably mounted on the handle end of the crankshaft 13 via a rotating shaft;

[0038] The guide sleeve 16 is rotatably mounted on the upper surface of the storage bin 7 via a rotating shaft, and the guide rod 15 is movably mounted on the guide sleeve 16;

[0039] The spring 17 is sleeved on the guide rod 15 and is clamped between the handle end of the crankshaft 13 and the guide sleeve 16.

[0040] By adopting the technical solution disclosed in this utility model, it is possible to achieve:

[0041] When the device is used, the oxygen candles for oxygen production are arranged in the storage bin 7, and the oxygen candles in the storage bin 7 are pressed against the connecting seat 10, and then the connecting seat 10 and the support seat 8 are pushed to the end of the storage bin 7 away from the reaction bin 1. At this time, the spring 9 on the support seat 8 is compressed and pressed, thereby pressing the arranged oxygen candles against the side wall of the rotary bin 2; when oxygen production is needed, the rotary bin 2 is rotated in one direction, and when the position of the rotary bin 2 is rotated and docked with the storage bin 7, the oxygen candles in the storage bin 7 are pushed into the position of the rotary bin 2, and when the rotary bin 2 drives the oxygen candles to rotate to the exhaust port 4, the ignition rod 3 is pressed against the oxygen candles, and then the ignition rod 3 is rotated to rub with the oxygen candles to ignite the oxygen candles and release oxygen. After a single oxygen candle is burned out, the rotary bin 2 is rotated to rotate the oxygen candle waste to the waste outlet 6, and then the waste door 5 is closed. The position of the rotary bin 2 is opened for cleaning, and the empty position is filled with oxygen candles during the rotation of the rotary bin 2; when the rotary bin 2 is rotated, the crankshaft 13 is manually rotated, and then the crankshaft 13 drives the driven gear 14 to rotate one circle, that is, the driven gear 14 drives the driving gear 12 to rotate 1 / 3 of a circle, that is, the driving gear 12 and the rotary bin 2 rotate at the same angle, to achieve a single rotation of the crankshaft 13, that is, to push a new oxygen candle position to dock with the exhaust port 4; when the crankshaft 13 is rotated, the first half circle of the crankshaft 13 is to push the guide rod 15 to tighten the spring 17, and the crankshaft 13 is released after it rotates more than half a circle, and the spring 17 pushes the crankshaft 13 to complete the remaining half circle and limits the crankshaft 13, thereby ensuring that the single rotation of the crankshaft 13 remains one circle.

[0042] The technical advantages that can be achieved by adopting the above technical solution are as follows:

[0043] This device is provided with a reaction chamber 1 with a storage chamber 7 and a rotary chamber 2 with multiple positions, so that the oxygen-generating medicine box can store multiple oxygen candles at a time, and when needed, the oxygen candles can be sent out one by one for oxygen-generating combustion by rotating the rotary chamber 2.
