[0012] Beneficial effects of the present invention:

[0013] The device provides a self-inflating and leak-proof universal oil bottle cap for quantitative oil discharge. A cap is arranged at the oil bottle mouth, and an extension tube, a high-pressure body and other devices are arranged inside the cap. The outside air can be squeezed into the high-pressure body by squeezing the oil bottle, and the high-pressure gas in the high-pressure body provides pressure for the oil bottle to discharge the oil. A high-pressure chamber, a sealing plate and an adjustment limit catch are arranged inside the high-pressure body. The adjustment limit catch can slide in the high-pressure chamber, and the sealing plate pushes the air in the high-pressure chamber to be discharged outward for a certain distance and then is caught by the adjustment limit catch, thereby controlling the volume of the gas sprayed out of the high-pressure chamber, thereby controlling the volume of the oil sprayed out of the oil bottle. The position of the adjustment limit catch can be adjusted by turning the adjustment knob, and the adjustment is relatively convenient, so that the volume of the oil poured each time remains roughly consistent.

[0014] The device is provided with a limit roller, a circular stopper, a support rod, a reset shell, a reset slider, etc. in the extension tube pipeline. When the extension tube is filled with high-pressure viscous oil, the circular stopper is pushed outward, and the limit roller pushes the circular stopper to rotate a certain angle, and the oil flows out from the gap between the circular stopper and the side of the extension tube. When the internal air pressure of the device is reduced, the spring pulls the circular stopper to reset through the support rod to block the outlet of the extension tube. The spring continues to pull the circular stopper inward, and the circular stopper can absorb a part of the viscous oil at the outlet of the oil outlet chamber and flow it back into the oil outlet chamber, thereby avoiding the generation of excess oil at the outlet of the oil outlet chamber. The device is suitable for relatively viscous oil, such as consumable oil. If the oil viscosity is low, it is necessary to reduce the diameter of the oil outlet chamber opening.

[0015] The device is provided with a gravity switch, an extension tube, an oil outlet head and an oil suction ring groove on one side of the cover. The oil discharged from the bottle flows outward through the gravity switch and the extension tube. When the pressure in the bottle is insufficient, the oil stops flowing out, and a part of the residual oil remains at the opening of the oil outlet cavity. The bottle is placed upright and the oil bottle is squeezed. The outside air flows inward through the opening of the oil suction ring groove and pushes the residual oil near the oil outlet cavity back into the bottle, thereby accelerating the recovery of the residual oil.

[0016] The device is provided with an intermediate cavity, a mass block, a movable cavity, a switch mass block, an air inlet groove, etc. When the device is placed forward, the high-pressure chamber is subjected to individual pressure, the pressure-bearing requirement of the bottle is reduced, and the manufacturing cost of the oil bottle is reduced; when the device is inverted, the mass block automatically opens the air outlet due to the influence of gravity, the switch mass block opens the oil outlet due to the action of gravity, and the oil automatically sprays out due to the action of the internal pressure; the mass block blocks the air inlet groove, and the oil is prevented from entering the high-pressure chamber, and there is no need to manually open the redundant switches. The sealing is guaranteed when the device is placed forward, and the oil outlet switch mode is related to the bottle posture, which is simple to operate, flexible, convenient and quick to use, and prevents external dust from entering the bottle through the opening.

[0026] The flexible bottle 10 is filled with a certain amount of oil, and the flexible bottle 10 is squeezed repeatedly, and the outside air flows into the flexible bottle 10 through the oil suction ring groove 42, the negative pressure hole 43, the concentration cavity 44, and the suction pipe 16. The outside air enters the bottle through the one-way valve 27 on the cover 11, and the air is squeezed into the high-pressure chamber 24 in one direction. The air pushes the sealing plate 25 to squeeze the pressure spring 50, and a certain amount of high-pressure gas accumulates in the high-pressure chamber 24. After the device is inverted, the gas in the high-pressure chamber 24 flows out, the air pressure in the flexible bottle 10 increases, the opening in the gravity switch 12 opens, and the liquid passes through the gravity switch 12, the extension tube 13, and the oil outlet cavity. 41 flows out to the outside to complete a quantitative oil injection action. During this process, the upper and lower positions of the limit grip 23 are adjusted to control the limit position of the downward movement of the sealing plate 25, thereby controlling the volume of the air pushed by the sealing plate 25 to be ejected, thereby controlling the air pressure in the flexible bottle 10, thereby quantifying the amount of oil sprayed by the device at one time. After one spraying is completed, when it is used next time, the flexible bottle 10 is squeezed, and the outside air flows into the flexible bottle 10 through the oil suction ring groove 42. The airflow blows the residual liquid around the oil outlet cavity 41 into the oil suction ring groove 42 and the negative pressure hole 43, completing the recovery of the residual oil and avoiding the oil stains at the bottle mouth to naturally remain on the outside of the bottle body.

[0027] Preferably, an active cavity 45 is provided in the gravity switch 12, and a switch mass block 46 is slidably provided in the active cavity 45.

A connecting groove 48 is provided on the side wall of the active cavity 45, and the lower opening of the connecting groove 48 is located at the lower side of the active cavity 45.

[0028] When the device is placed forward, the switch mass block 46 is located at the lower side of the active cavity 45, and the switch mass block 46 blocks the lower opening of the connecting groove 48, thereby cutting off the connection between the flexible bottle 10 and the outside world, thereby achieving sealing. When the device is placed reversely, the switch mass block 46 moves to the upper side of the active cavity 45, and the lower opening of the connecting groove 48 connects the inside and outside of the cover 11. The inside of the flexible bottle 10 is connected to the extension tube 13 and the oil outlet cavity 41 through the oil passage 47 and the connecting groove 48, thereby achieving the purpose of automatically opening or closing the oil outlet opening according to the bottle posture.

The side wall of the high-pressure chamber 24 is located at the upper side wall of the sealing plate 25 and a limit ring 26 is provided.

[0030] When air enters the high-pressure chamber 24, the air pushes the sealing plate 25 to squeeze the pressure spring 50 until the sealing plate 25 is against the limit ring 26. The limit ring 26 plays a limiting role and is affected by the rotation of the adjustment knob 17. The adjustment knob 17 rotates relative to the adjustment threaded shaft 21, and the adjustment threaded shaft 21 moves up and down. The adjustment threaded shaft 21 drives the adjustment limit grip 23 to slide up and down. The up and down movement of the adjustment limit grip 23 can control the limit position of the downward movement of the sealing plate 25, thereby controlling the volume of air pushed out by the sealing plate 25, thereby achieving the purpose of manually controlling the amount of oil sprayed each time.

[0031] Preferably, a dial 18 is provided on the upper surface of the adjustment knob 17 , and a straight needle 19 is provided on the upper side of the cover 11 around the adjustment knob 17 .
