The upper part of the cavity 20 includes a cylindrical sidewall 26, and the cover plate 40 is snapped into the upper end of the cylindrical sidewall 26. The bottom plate 24 of the cavity 20 also serves as the bottom plate of the bottle cap 200. An oil outlet 21 is located at the front of the cavity 20 along the longitudinal direction (X-axis).

[0028] The electric pump 50 can be a 310 micro DC electric pump. The electric pump 50 includes an oil inlet pipe 51 and an oil outlet pipe 52. The oil inlet pipe 51 of the electric pump 50 passes through the bottom plate 24 of the machine cavity 20 and is inserted into the inner cavity of the bottle body 100. The oil inlet 511 of the oil inlet pipe 51 is located at the lower part of the inner cavity of the bottle body 100. The oil outlet 521 of the electric pump 50 oil outlet pipe 52 is connected to the oil outlet 21 on the upper part of the bottle cap 200. In this embodiment, the oil outlet 21 of the bottle cap 200 has an oil outlet hole 211, and one end of the electric pump 50 oil outlet pipe 52 with the oil outlet 521 is inserted into the oil outlet hole 211.

[0029] The control circuit includes a microcontroller (MCU), a keyboard, a tilt sensor (accelerometer), and an electric pump drive circuit. The power input of the electric pump drive circuit is connected to battery 60, and the power input of the electric pump 50 is connected to the output of the electric pump drive circuit. The control terminal of the electric pump drive circuit is connected to the microcontroller. The keyboard includes fuel volume increment / decrement buttons, and their signal outputs are connected to the microcontroller's electric pump operation time increment / decrement signal input. The tilt sensor's signal output is connected to the corresponding signal input of the microcontroller.

[0030] The electric pump drive circuit can be a relay drive circuit, a transistor drive circuit, a MOSFET drive circuit, or a DC motor drive chip.

[0031] The control circuit includes a main control circuit board 70, a power supply circuit board 80, and a power button 28.

[0032] A microcontroller (MCU), keyboard, electric pump drive circuit, tilt sensor 71, and display screen 72 are arranged on the main control circuit board 70. The display screen 72 is connected to the display signal output terminal of the microcontroller. The main control circuit board 70 is arranged in the machine cavity 20A, above the electric pump 50 and battery 60.

[0035] In this embodiment, the oil dispensing increment / decrease buttons include an increase button 73 and a decrease button 74. The signal output of the increase button 73 is connected to the input signal of the microcontroller regarding the increase in the electric pump's operating time, and the signal output of the decrease button 74 is connected to the input signal of the microcontroller regarding the decrease in the electric pump's operating time. Structurally, the oil dispensing increment / decrease buttons employ microswitches with a return spring. In this embodiment, the display screen 72 is a digital screen that displays the final oil dispensing volume in milliliters set by the oil dispensing increment / decrease buttons. Each press of the increase button 73 increases the oil dispensing volume by 5 ml, and each press of the decrease button 74 decreases the oil dispensing volume by 5 ml.

[0036] In another embodiment, the dispensing volume adjustment buttons can be replaced by a single dispensing mode setting button. The mode signal output of the dispensing mode setting button is connected to the mode signal input of the microcontroller. Each press of the dispensing mode setting button switches between a large-capacity mode and a small-capacity mode. The large-capacity mode sets the dispensing volume to 30ml, and the small-capacity mode sets the dispensing volume to 5ml. In this case, a display screen is not required on the main control circuit board 70; only a mode indicator light is needed.

[0037] In another embodiment, the dispensing volume increment / decrement button can also be a single dispensing volume increment button. The initial dispensing volume is set to 5ml, and each press of the dispensing volume increment / decrement button increases the dispensing volume by 5ml until the maximum dispensing volume of 50ml is reached. After reaching the maximum dispensing volume of 50ml, pressing the dispensing volume increment button again will return the set dispensing volume to the initial dispensing volume of 5ml, and this cycle repeats.

[0038] The lower part of the machine cavity 20 has an annular groove around its outer periphery, and an elastic sealing ring 25 is installed in the annular groove. The lower part of the machine cavity 20 is sealed to the bearing hole 12 of the cover 10 by the elastic sealing ring 25.

Buckle 31 includes a button 311 and a hook 312, with the hook 312 located below the button 311 and its hook head facing outwards. A spring seat 313 is located inside the button 311. The machine cavity 20 includes a buckle mounting groove 27 corresponding to the buckle 31, with a button hole 271 at its upper part. Buckles 31 and the compression spring 33 are arranged in the buckle mounting groove 27, and the button 311 of the buckle 31 is arranged in the button hole 271. A gap Δ is left between the inner side of the buckle 31 and the bottom of the buckle mounting groove 27 to facilitate pressing the buckle 31 inwards. The compression spring 33 is installed between the bottom of the buckle mounting groove 27 and the spring seat 313 of the button 311. The inner wall of the cover receiving hole 12 includes a groove 13 corresponding to the buckle hook 312. The hook 312 of the buckle 31 hooks the upper edge of the groove 13.

[0040] The button hole 271 of the snap-fit ​​mounting groove 27 is opened on the cylindrical side wall 26. The upper end of the snap-fit ​​mounting groove 27 is open, and the opening at the upper end of the snap-fit ​​mounting groove 27 serves as the entry port for the snap-fit ​​31. When the button 311 is pressed, the hook 312 at the lower end of the snap-fit ​​31 disengages from the groove 13. At this time, the machine part cavity 20 can be removed from the receiving hole 12.

[0041] The working process of the intelligent quantitative oil bottle in this embodiment of the invention is as follows:

[0042] When the user presses the power button 28, the battery 60 supplies power to the main control circuit board 70 through the push-button power switch 81 on the power circuit board 80. The display screen (digital screen) 72 displays the initial oil output value or the previously set oil output value, and the intelligent quantitative oil bottle is in standby mode.

[0043] If the oil dispensing volume displayed on the screen 72 meets the user's needs, the user can directly pick up the smart metering oil bottle and pour oil; if the oil dispensing volume displayed on the screen 72 does not meet the user's needs, the user can adjust the oil dispensing volume displayed on the screen 72 by pressing the oil dispensing volume increase button 73 or the oil dispensing volume decrease button 74. At the same time, the controller stores the data to meet the user's requirements and stores the user data.

[0044] When the user tilts the oil bottle to the set angle, the tilt sensor sends a signal to the microcontroller (MCU), which controls the operation of the electric pump based on the user data. The MCU sends a control signal to the electric pump drive circuit, which then supplies power to the electric pump. After the electric pump starts working, the oil outlet 21 begins to dispense oil.

[0045] When the oil output of the oil nozzle 21 reaches the value displayed on the display screen (digital screen) 72, the microcontroller (MCU) sends a control signal to the electric pump drive circuit, the electric pump drive circuit stops supplying power to the electric pump, and after the electric pump stops working, the oil nozzle 21 stops discharging oil.

[0046] After the user finishes pouring the oil and straightens the tilted oil bottle, the tilt sensor sends a signal to the microcontroller again, and the microcontroller (MCU) returns to standby mode.

[0047] In this embodiment of the intelligent metering oil bottle, the microcontroller monitors the operating time of the electric pump in real time during the oil dispensing process. Once the electric pump's operating time reaches the time corresponding to the preset oil dispensing volume, the microcontroller cuts off the power to the electric pump, ensuring that the oil dispensing volume meets the set quantitative value. This invention provides high precision in quantitative adjustment, avoiding both waste caused by excessive dispensing and underdispensing that affects usability.
