An electronic cigarette capable of automatically and accurately supplying oil

Abstract

The utility model relates to an automatic precision oil supply's electronic cigarette, including shell and set up in the inside atomizer, battery host computer, oil storage bottle and pump oil subassembly of shell, atomizer and oil storage bottle all are detachable with shell, and the bottom of atomizer is provided with oil inlet hole, pump oil subassembly includes oil pump, oil inlet pipe and oil outlet pipe, and the both ends of oil inlet pipe are connected respectively oil storage bottle and the oil inlet of oil pump, and the both ends of oil outlet pipe are connected respectively the oil outlet of oil pump and the oil inlet hole of atomizer. Through setting up oil storage bottle and pump oil subassembly, when the tobacco tar in the atomizer is close to complete use, needs to add tobacco tar, battery host computer controls pump oil subassembly and pumps oil from oil storage bottle to the oil storage cavity of atomizer, and battery host computer will control the pump oil amount according to the oil storage cavity capacity size, realizes automatic precision pump oil, and moreover, still be provided with liquid level monitoring component in oil storage bottle, can replace in time before the tobacco tar in oil storage bottle is exhausted, avoids the risk that the oil storage bottle oil volume is insufficient and cannot fully supply oil to the atomizer to cause the atomizer dry burning or the risk that burns the paste.

Claims

1. An electronic cigarette with automatic and precise oil supply, characterized in that, The device includes a housing, an atomizer, a battery unit, an oil reservoir, and a pump assembly. The atomizer, battery unit, oil reservoir, and pump assembly are all housed within the housing, and the atomizer and oil reservoir are detachable from the housing. The atomizer has an oil inlet at its bottom. The pump assembly includes an oil pump, an inlet pipe, and an outlet pipe. The inlet pipe is connected to the oil reservoir and the inlet of the oil pump at both ends, and the outlet pipe is connected to the outlet of the oil pump and the inlet of the atomizer at both ends.

2. The electronic cigarette of claim 1, wherein, The atomizer includes a housing, a base, an atomizing core, and a dividing sleeve. The base is inserted into one end of the housing, and the dividing sleeve divides the interior of the housing into an oil storage chamber and an atomizing chamber. The base is symmetrically provided with two oil inlets, and the oil outlet pipe is inserted in a "Y" shape into the oil inlets and communicates with the oil storage chamber.

3. The electronic cigarette of claim 2, wherein, The oil storage cavity is filled with oil-absorbing cotton, which is used to absorb e-liquid.

4. The electronic cigarette of claim 3, wherein, The oil outlet pipe is inserted at one end of the oil storage cotton with a beveled end face.

5. The electronic cigarette of claim 4, wherein, The oil storage chamber is provided with a first sealing element and a second sealing element at both ends. The first sealing element has a pressure relief channel, which connects the oil storage chamber and the atomizing chamber.

6. The electronic cigarette of claim 5, wherein, The oil storage bottle includes a bottle body, a top cover, a bottom cover, and a piston. The top cover and the bottom cover are respectively disposed at both ends of the bottle body. The piston is housed in the bottle body. The top cover has an air inlet, and the bottom cover has an oil outlet. The oil outlet pipe is connected to the oil storage bottle through the oil outlet. The piston moves as the e-liquid level rises and falls.

7. The electronic cigarette of claim 6, wherein, The oil storage bottle also includes a sealing plug, which is adjacent to the base and the edge of the sealing plug is interference-fitted with the bottle body. The oil outlet pipe passes through the oil outlet hole and communicates with the sealing plug and the oil storage bottle.

8. The electronic cigarette of claim 7, wherein, The oil storage bottle is also equipped with a liquid level monitoring component to monitor the amount of e-liquid in the oil storage bottle.

9. The electronic cigarette of claim 8, wherein, The liquid level monitoring component includes a magnetic element and a Hall effect device, which are respectively disposed on the piston and the sealing plug; or The liquid level monitoring component includes a first capacitor and a second capacitor, the first capacitor and the second capacitor being respectively disposed on the piston and the sealing plug; or The liquid level monitoring component includes a liquid level sensor, which is disposed on the side wall of the oil storage cavity near the sealing plug; or The liquid level monitoring component includes a pressure sensor, which is disposed on the sealing plug; or The liquid level monitoring component includes a mechanical tactile switch disposed on the sealing plug.

10. The electronic cigarette with automatic and precise oil supply according to claim 8, characterized in that, The oil pump includes a power unit and a transmission unit. The oil inlet pipe and the oil outlet pipe are respectively connected to the oil inlet and oil outlet of the transmission unit. The power unit drives the transmission unit to move so that the e-liquid bottle adds e-liquid into the atomizer. The power unit is electrically connected to the battery host, and the battery host controls the power unit to automatically and accurately supply oil.
