Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 - 3 As shown, the disposable electronic cigarette smoking device with easy oil filling of this embodiment includes an atomizer assembly 200 and a battery assembly 300. The atomizer assembly 200 includes an oil cup shell 100, an airway 21, an oil cup 22, a base 23, and a hollow heating core 24. The oil cup shell 100 includes a suction nozzle 101, an atomizer chamber 102, a battery chamber 103, and an intermediate baffle 104. The oil cup shell 100 is integrally formed, and the oil cup 22 is fixed to the base 23 to form a bottom-sealed atomizer device. The atomizer device is arranged in the atomizer chamber 102, and the battery chamber 103 is used to install the battery assembly 300. The intermediate baffle 104 is arranged between the atomizer chamber 102 and the battery The atomizing chamber 102 and the battery chamber 103 are arranged between the two chambers, so that the atomizing chamber 102 and the battery chamber 103 form independent spaces respectively; one end of the heating core 24 is connected with a lead wire 241, the number of the lead wires is not less than 2, at least one is a negative electrode and the other is a positive electrode, and the airway 21 is arranged in the middle of the heating core 24; the base 23 is arranged at the bottom of the oil cup 22, the base 23 is made of silicone material, and a lower airway opening 221, an oil filling hole 222, and a lead hole 223 are opened on its surface, and the number of the oil filling holes 222 and the lead hole 223 matches the number of the lead wires; the heating core 24 is arranged above the lower airway opening 221, and the lead wire 241 passes through the lead hole 223 and extends to the middle of the inner wall of the oil filling hole 222.

[0032] like Figures 4 - 7As shown in the figure, the battery assembly 300 of this embodiment includes a housing 31, a tail cover 32, a battery 33, a control board 34, an electrode 35, an air inlet hole 37 and an air outlet hole 38. The housing 31 and the tail cover 32 are fixedly connected to form a sealed space. The battery 33 and the control board 34 are arranged inside the housing 31. An air switch controller 39 is provided on the control board 34. The controller 39 and the air inlet hole 37 are arranged below the control board 34. An air port is also provided on the control board 34 so that gas can flow into the air outlet hole 38. The controller 39 is directly connected to the control board 34 by welding. One end of the electrode 35 is welded to the control board 34, and the other end of the electrode 35 penetrates the upper surface of the housing 31 and can be in interference fit with the oil injection hole 222. When the electrode 35 is inserted into the oil injection hole 222, the lead wire 241 extending into the oil injection hole 222 through the lead wire hole 223 can be connected to the electrode 35, so that while realizing the electrical connection between the electrode and the atomization assembly, the atomization assembly can be sealed at the same time.

[0033] Further, as Figures 3 - 4 shown, one end of the electrode 35 connected to the oil injection hole 222 is a stepped structure. The upper part is a small-diameter cylinder 351, and the middle part is a large-diameter cylinder 352. A small-diameter round hole 2221 and a large-diameter round hole 2222 matching the electrode 35 are provided in the oil injection hole 222, so as to form a tight fit connection between the electrode 35 and the oil injection hole 222, so that the electrode 35 and the oil injection hole can be better sealed. The lead wire 241 extends to the side wall of the large-diameter round hole 2222 of the oil injection hole 222, rather than extending into the small-diameter round hole 2221, so that the lead wire 241 does not penetrate the oil injection hole 222. Further, a third cylinder 353 is provided at the bottom of the large-diameter cylinder 352.

In the battery assembly 300 of this embodiment, the air inlet 37, the air port on the control panel 34, and the air outlet 38 are connected to form an air path, and the controller 39 is arranged in the air path. After the atomizer assembly 200 and the battery assembly 300 of this embodiment are filled with oil and assembled, the lower airway opening 221 of the atomizer assembly is connected to the air outlet 38 of the battery assembly. When external air enters the air path, the controller 39 is triggered to turn on the switch, and the circuit of the battery assembly 300 and the atomizer assembly 200 is connected, and the electronic cigarette can be powered on and work.

Assemble the components of the atomizer assembly 200 in sequence, install the atomizer device in the atomizer chamber 102 of the oil cup housing 100, so that the atomizer assembly 200 forms an integrated independent component, and assemble the components of the battery assembly 300 in sequence, so that the battery assembly 300 forms an integrated independent component, so that the atomizer assembly 200 and the battery assembly 300 can be transported in a separated manner;

[0041] 2. Inject specific smoke oil into the atomizer assembly 200 as needed, specifically including: placing the atomizer assembly 200 with one end of the oil injection hole 222 facing upward, and injecting a proper amount of smoke oil into the oil cup 22 through the oil injection hole 222;

[0042] 3. After the oil filling is completed, align the battery 33 of the battery assembly 300 with the battery cavity 103 of the atomizer assembly 200 and push them inward, and apply external force to make the atomizer assembly 200 and the battery assembly 300 snap into one body. At the same time, the electrode 35 can be interference-fitted with the oil filling hole 222, so that the oil filling hole 222 is completely sealed, thereby obtaining a finished disposable electronic cigarette that can be used directly.

[0043] When the present invention is in the market circulation, the e-cigarette middleman can inject specific e-cigarette oil into the atomization component as needed, and then assemble the atomization component and the battery component to obtain the final disposable e-cigarette product. The present invention can realize the connection between the atomization component and the battery component without welding, and at the same time, it can also realize the sealing of the oil injection hole without additionally providing an oil plug or other sealing parts. The assembly and oil injection processes are simple and fast, and it is especially suitable for being widely promoted as an e-cigarette intermediate product.
