[0040] The working principle of the quantitative oil bottle of the embodiment 1 of the utility model is shown in Figures 6 to 9 as follows, including the following working steps:

[0041] 1) as shown in Figure 6 , pour (stand on one's head) the quantitative oil bottle along the longitudinal direction (X-axis direction), so that the oil outlet pipe 232 of the siphon pipe 23 is vertically downward, at this time, the oil liquid in the inner cavity of the glass bottle body 100 flows into the quantitative cavity 20A from the oil inlet hole 211 on the bottom plate 21, at the same time, the air enters the oil outlet pipe 232 of the siphon pipe 23, flows into the upper part of the oil liquid in the inner cavity of the glass bottle body 100 through the air guide pipe 60, and fills the vacuum formed by the outflow of the oil liquid in the inner cavity of the glass bottle body 100; the air above the liquid surface in the quantitative cavity 20A flows out from the air vent hole 224 on the top plate 22 due to the decrease of the space caused by the inflow of the oil liquid.

[0042] 2) as shown in Figure 7 , the liquid level in the quantitative cavity 20A gradually rises, when the oil liquid enters the connecting part 233 from the oil inlet pipe 231 of the siphon pipe 23, the oil liquid entering the connecting part 233 blocks the air passage between the oil outlet pipe 232 and the air guide pipe 60, the air no longer enters the inner cavity of the glass bottle body 100, and the vacuum is formed in the upper part of the oil liquid in the inner cavity of the glass bottle body 100, so that the oil liquid in the inner cavity of the glass bottle body 100 stops flowing into the quantitative cavity 20A from the oil inlet hole 211 on the bottom plate 21.

[0043] 3) as shown in Figure 8 , due to the fact that the space above the liquid surface in the quantitative cavity 20A is connected with the atmosphere through the air vent hole 224, the oil liquid in the quantitative cavity 20A flows out through the oil outlet pipe 232 of the siphon pipe 23 under the siphon effect, the liquid surface in the quantitative cavity 20A gradually decreases, and the space vacated by the outflow of the oil liquid in the quantitative cavity 20A is supplemented by the inflow of the air through the air vent hole 224.

[0044] 4) as shown in Figure 9 , when the liquid surface in the quantitative cavity 20A drops to the inlet position of the oil inlet pipe 231 of the siphon pipe, the siphon effect stops, and the oil outlet pipe 232 of the siphon pipe 23 stops the outflow of oil; the amount of oil outflowed by the quantitative oil bottle at one time corresponds to the volume of oil corresponding to the vertical distance H between the inlet of the oil inlet pipe 231 and the bottom of the oil inlet pipe 231 in the quantitative cavity 20A.

[0045] 5) If the once ration is enough, the pouring (inverted) ration oil bottle can be restored to the upright state, and the oil output is stopped. If the oil output needs to continue, the ration oil bottle can be kept in the pouring (inverted) state, and the ration oil bottle will repeat the steps 1 to 4, and each cycle flows out the oil volume corresponding to the vertical interval H as shown, and the ration oil bottle pours out the integer times of the oil volume of the approved ration once. Figure 9

[0046] The structure of the ration oil bottle of the embodiment 2 is as shown in Figure 10 The difference between the embodiment 2 and the embodiment 1 is only that the siphon pipe 23 is replaced by the U-shaped elbow pipe instead of the nested pipe of the embodiment 1, the working principle is completely the same, and other structures are also completely the same.​
