A receiving chamber is provided between the oil inlet outer cap 311 and the oil inlet inner cap 312, and an impeller 313 is positioned in the receiving chamber and fixedly connected with the rotation shaft of the rotation driving unit 20.
The oil inlet cover 311 is provided with a first oil inlet channel 3111 and a first exhaust port 3112 which are communicated with the accommodating cavity, and an exhaust valve is arranged in the first exhaust port 3112.
A second oil inlet passage (not shown) communicating with the receiving chamber is formed in the oil inlet cover 312.
An oil path communicating with the second oil inlet passage is provided in the inner side wall of the casing 10.
The oil outlet cap 32 includes an oil outlet cover 321 disposed away from the rotation driving unit 20, an oil outlet inner cover 322 disposed close to the rotation driving unit 20, and balls 323.
The oil outlet cover 321 is provided with a first oil outlet channel 3211 and a first air outlet hole 3212.
The second oil outlet passage is provided in the inner oil outlet cover 322 corresponding to the first oil outlet passage 3211, and the second air outlet hole 3222 is provided corresponding to the first air outlet hole 3212.
A ball accommodating cavity communicated with the first air exhaust hole 3212 and the second air exhaust hole 3222 is arranged between the oil outlet outer cover 321 and the oil outlet inner cover 322, and the ball 323 is positioned in the ball accommodating cavity.
In the present embodiment, the rotation driving unit 20 is a motor, and one end of the motor facing the oil outlet cap 32 is provided with the brush 21.
Referring to fig. 2 and 4, an electrode slot is further formed on the oil outlet cover 321, and an electrode 3213 connected to the brush 21 is disposed in the electrode slot.
Referring to fig. 3, a second oil outlet channel 3221 and a second air outlet hole 3222 are formed in the oil outlet inner cover 322 and are communicated with the oil path of the housing 10. An axial hole 3223 is provided in the middle of the side of the oil outlet inner cap 322 facing the rotation driving unit 20, and the center axis of the rotation driving unit 20 is located in the axial hole 3223.
The oil outlet inner cover 322 is provided with mounting grooves 3224 at two sides of the shaft hole 3223 respectively, the electric brush 21 is arranged on a brush frame, the brush frame is provided with two supporting legs, and the two supporting legs of the brush frame are positioned in the mounting grooves 3224.
Referring to fig. 5 to 7, a partition 3228 is provided in the oil outlet inner cap 322, and the second air outlet aperture 3222 protrudes from the partition 3228 toward one end of the ball 323. The end of the second exhaust hole 3222 facing the ball 323 has an inner sidewall 32221 and an outer sidewall 32222, and the height of the outer sidewall 32222 relative to the partition plate 3228 is greater than the height of the inner sidewall 32221 relative to the partition plate 3228.

The height of inner side 3226 of groove 3225 relative to spacer 3228 is greater than the height of outer side 3227 relative to spacer 3228. This ensures that there is no seal between the ball 323 and the end of the second air outlet 3222 facing the ball 323, and air or petrol can enter the ball receiving chamber from the second air outlet 3222.
Air enters the ball receiving chamber through the groove 3225 of the second air discharge hole 3222, and the flow force of the air pushes the ball 323 to be fixed, since the flow force of the air is much smaller than the gravity of the ball 323, the ball does not move, so the first air discharge hole 3212 is not closed, and the air can be discharged through the first air discharge hole 3212.
After the air is exhausted, as a pressure difference is formed between the inside and the outside of the pump, the gasoline enters the ball accommodating cavity through the second exhaust hole 3222, the flowing force of the gasoline is far greater than the gravity of the ball 323, and the flowing of the air flow drives the ball 323 to move towards the first exhaust hole 3212 and seal the first exhaust hole 3212. After the ball 323 closes the first air outlet 3212, the gasoline is not discharged from the first air outlet 3212.
This facilitates the evacuation of the oil passages of the housing 10 and the air in the oil outlet end cap 32, accelerating the pumping out of the gasoline.
