In order to make the oil pot can accommodate more oil as much as possible, the oil pipe is inclined upwards, so that the oil nozzle can have a certain height to ensure higher than the oil surface. . Since the oil discharge nozzle is at a position higher than the oil surface, when the oil in the bottle is not much, the oil needs to flow from the bottom of the bottle body to the oil outlet pipe in the upper part of the bottle body, and the oil discharge path is long; and the oil itself has adhesion, when the oil When there are few, the speed of the flow along the inner wall of the bottle is slow. It can be seen that the oil flow rate of the traditional oil pot is slow, and in many cases, the time for draining oil is high, so it is necessary to develop a fast oil output. Oil can.

In order to overcome the above problems, it is thought that the oil discharge pipe is disposed at the bottom position of the bottle body, so that even if there is only a small amount of oil, it can quickly flow into and out of the oil pipe. However, when the oil pipe is located at the bottom of the bottle body, the oil will automatically flow out of the oil pipe under the influence of the atmospheric pressure. The existing sealing technology is inconvenient to operate when opening or closing the oil nozzle, and it is easy to drip, and the existing When the oil nozzle is facing upwards, after the oil is poured, the bottle body is tilted from the inclined state, and the outer wall of the oil pipe is attracted downward toward the oil in the oil nozzle, causing the oil to flow down the outer wall of the oil pipe, wasting oil. It also pollutes the outer wall of the bottle. Therefore, it is necessary to develop an oil can that automatically closes the oil discharge nozzle after the oil is poured, and the oil discharge nozzle does not drip; when the oil is required to be poured, the oil discharge nozzle automatically opens.

The oil is squeezed under the action of atmospheric pressure and opens the first check valve so that the oil enters the auxiliary oil chamber. After the oil in the auxiliary oil chamber reaches a certain amount, the push-pull portion is pressed, and the oil in the auxiliary oil chamber is pressed by the pressing portion of the piston rod, and the oil is pressed to open the second one-way valve, and the oil is discharged from the oil discharge nozzle. Flow out. Therefore, the oil flows out under the influence of the squeezing force, so the flow rate is fast and the oil discharge time is short; at the same time, even if the oil content in the bottle is small, the oil discharge speed is not affected.

After the oil in the auxiliary oil chamber is poured, the pressing force acting on the second one-way valve disappears, and the second one-way valve is automatically closed. At this time, since the second one-way valve has a certain opening pressure, The oil in the oil passage and the oil discharge pipe cannot flow through the second check valve, that is, the oil cannot continue to flow out. Moreover, due to the downward design of the oil discharge nozzle, the outer wall near the oil discharge nozzle forms a downward attraction force to the oil in the oil discharge nozzle, and the oil in the oil discharge nozzle remains in the oil discharge nozzle under the action of its own surface tension, that is, There will be a problem with dripping.
