[0030] The present application proposes an electronic cigarette, which includes a shell, an atomization component, a nozzle, an air duct and an oil filling pipe; an oil storage chamber and an oil supply chamber are formed inside the shell, and the oil supply chamber is located below the oil storage chamber; the atomization component is arranged in the oil storage chamber; the nozzle is arranged above the shell, and a mist suction channel and an oil suction channel connected to the outside are formed inside the nozzle, and the mist suction channel is connected to the atomization component; the oil filling pipe is sequentially penetrated through the oil suction channel, the oil storage chamber and the oil supply chamber, the bottom end of the oil filling pipe is located at the bottom of the oil supply chamber, the oil filling pipe is located on one side of the atomization component, and a plurality of oil filling holes are opened on the part of the oil filling pipe located in the oil storage chamber; wherein, the length of the oil filling pipe is 5 to 20 cm, the inner diameter of the oil filling pipe is 1.5 to 2.0 mm, and the diameter of the oil filling hole is 0.5-1.0 mm.

[0031] In the electronic cigarette of the present application, when the user draws inhalation, negative pressure is formed in the oil suction channel, and the oil in the oil supply chamber flows into the oil filling tube, and flows into the oil storage chamber through the oil filling hole opened on the oil filling tube, so that the electronic cigarette of the present application can be filled with oil through the user's suction, and the user does not need to manually supply oil to the oil storage chamber, and the user experience is good. In addition, the amount of oil filled in the oil storage chamber is positively correlated with the suction force and frequency of the user's suction, and the oil consumption of the oil in the oil storage chamber is also positively correlated with the frequency of the user's suction (some are also positively correlated with the suction force). Therefore, the electronic cigarette of the present application can also automatically adjust the content of the oil in the oil storage chamber, ensuring the stability of the oil content in the oil storage chamber, and the atomization effect of the atomization component is good and not easy to burn.

[0032] The following will mainly describe the specific structure of the electronic cigarette.

[0033] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes a housing 100. The housing 100 is provided with an oil storage chamber 110 and an oil supply chamber 120, and the oil supply chamber 120 is located below the oil storage chamber 110. The oil supply chamber 120 is used to store the oil and supply the oil to the oil storage chamber 110.

[0034] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes an atomizer assembly 130 , which is disposed in the oil storage chamber 110 . The atomizer assembly 130 is communicated with the oil storage chamber 110 , and the atomizer assembly 130 can atomize the tobacco oil in the oil storage chamber 110 .

[0035] See also Figure 1 and Figure 2The electronic cigarette 10 of the present application includes a nozzle 140, which is arranged above the housing 100. A mist suction channel 141 connected to the outside is formed inside the nozzle 140, and the mist suction channel 141 is connected to the atomizing assembly 130. The atomizing assembly 130 and the mist suction channel 141 can be sleeved, so that the connection effect between the two is better. The aerosol generated by the atomizing assembly 130 can flow out through the mist suction channel 141 in the nozzle 140 and be inhaled by the user.

[0036] Specifically, the electronic cigarette 10 of the present application includes an air guide tube (not shown), which is arranged in the housing 100, and the two ends of the air guide tube are respectively connected to the mist suction channel 141 and the atomization chamber of the atomization assembly 130, and the aerosol generated in the atomization chamber flows into the aerosol suction channel 141 through the air guide tube and is inhaled by the user. The air guide tube has a guiding and limiting effect on the flow of the aerosol.

[0037] See also Figure 1 and Figure 2 , an oil suction channel 142 connected to the outside is formed inside the suction nozzle 140. The electronic cigarette 10 of the present application includes an oil filling tube 150. The oil filling tube 150 is sequentially arranged in the oil suction channel 142, the oil storage chamber 110 and the oil supply chamber 120. The bottom end of the oil filling tube 150 is located at the bottom of the oil supply chamber 120. The oil filling tube 150 is located on one side of the atomization assembly 130. A plurality of oil filling holes 151 are provided on the portion of the oil filling tube 150 located in the oil storage chamber 110. When the user inhales, a negative pressure is formed in the oil suction channel 142, and the tobacco oil in the oil supply chamber 120 flows into the oil filling tube 150, and flows into the oil storage chamber 110 through the oil filling holes 151 provided on the oil filling tube 150. Therefore, the user does not need to manually supply oil to the oil storage chamber 110, and the user has a good experience. In addition, the amount of oil filled in the oil storage chamber 110 is positively correlated with the suction force and frequency of the user's puffing, and the oil consumption in the oil storage chamber 110 is also positively correlated with the frequency of the user's puffing (some are also positively correlated with the suction force). Therefore, the electronic cigarette 10 of the present application can also automatically adjust the content of the oil in the oil storage chamber 110, ensuring the stability of the oil content in the oil storage chamber 110, and the atomization effect of the atomization component 130 is good and the atomization component 130 is not easy to burn.

[0038] See also Figure 1 and Figure 2The oil suction channel 142 is formed by extending downward from the top inner wall of the suction nozzle 140, and the top wall of the suction nozzle 140 is provided with an oil suction hole 143 corresponding to the oil suction channel 142 and connected to the oil suction channel 142. The diameter of the oil suction hole 143 can be 0.2-1.0 mm, so that the smoke oil is not easy to flow out of the top of the oil filling tube 150 during suction. Further, the diameter of the oil suction hole 143 can be 0.25-1.0 mm, 0.6-1.0 mm, 0.7-1.0 mm, 0.5-0.6 mm, 0.55-0.8 mm, 0.75-0.85 mm, 0.8-1.0 mm, 0.5-0.7 mm, 0.6-0.8 mm, 0.85-1.0 mm or 0.5-0.9 mm, etc. Furthermore, the diameter of the oil suction hole 143 may be 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm or 1.0 mm, etc. The shape of the oil suction hole 143 may be various, and the shape of the oil suction hole 143 is not limited to a circle. The above diameter may be the diameter of the circumscribed circle of the oil suction hole 143.

[0039] The length of the oil filling tube 150 is 3 to 20 cm. Therefore, the length of the oil filling tube 150 is suitable, and the smoke oil will not flow out from the top of the oil filling tube 150 when the oil filling tube 150 fills the oil storage chamber 110. Further, the length of the oil filling tube 150 includes but is not limited to 3 to 6 cm, 5 to 15 cm, 3 to 5 cm, 4 to 8 cm, 7 to 15 cm, 10 to 12 cm, 5 to 10 cm, 6 to 13 cm, 15 to 20 cm, 13 to 15 cm, 12 to 18 cm, 17 to 20 cm, 14 to 16 cm or 8 to 15 cm. Furthermore, the length of the oil filling tube 150 includes but is not limited to 3cm, 3.5cm, 4cm, 4.5cm, 5cm, 5.5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 11cm, 12cm, 13cm, 14cm, 15cm, 16cm, 17cm, 18cm, 19cm or 20cm.

[0040] The inner diameter (inner wall diameter) of the oil filling tube 150 is 1.5-2.0 mm. Therefore, the inner diameter of the oil filling tube 150 is suitable, and the e-liquid will not flow out from the top of the oil filling tube 150 when the user inhales. Further, the inner diameter of the oil filling tube 150 includes but is not limited to 1.55-2.0 mm, 1.6-2.0 mm, 1.7-2.0 mm, 1.5-1.6 mm, 1.55-1.8 mm, 1.75-1.85 mm, 1.8-2.0 mm, 1.5-1.7 mm, 1.6-1.8 mm, 1.85-2.0 mm or 1.5-1.9 mm, etc. Furthermore, the inner diameter of the oil filling tube 150 includes but is not limited to 1.5 mm, 1.55 mm, 1.6 mm, 1.65 mm, 1.7 mm, 1.75 mm, 1.8 mm, 1.85 mm, 1.9 mm, 1.95 mm or 2.0 mm.

[0041] The diameter of the oil filling hole 151 is 0.5-1.0 mm. Therefore, the size of the oil filling hole 151 is relatively suitable, the oil storage chamber 110 can have a relatively good oil filling effect, and the smoke oil will not flow to the top of the oil filling tube 150. Further, the diameter of the oil filling hole 151 includes but is not limited to 0.55-1.0 mm, 0.6-1.0 mm, 0.7-1.0 mm, 0.5-0.6 mm, 0.55-0.8 mm, 0.75-0.85 mm, 0.8-1.0 mm, 0.5-0.7 mm, 0.6-0.8 mm, 0.85-1.0 mm or 0.5-0.9 mm, etc. Furthermore, the diameter of the oil injection hole 151 includes but is not limited to 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm or 1.0 mm, etc. The shape of the oil injection hole 151 is not limited to a circle, and the above diameter may also be the diameter of the circumscribed circle of the oil injection hole 151. The shape of the oil injection hole 151 may be a circle, a square, a racetrack, a star, a petal or a special shape, etc.

[0042] It can be understood that the length of the oil filling tube 150, the inner diameter of the oil filling tube 150, the diameter of the oil filling hole 151 and the size of the oil suction hole 143 are set in a related manner. When the user inhales, it is ensured that the oil storage chamber 110 can be filled with oil and the tobacco oil does not flow out of the oil filling tube 150.

[0043] See also Figure 1 and Figure 2 The oil filling pipe 150 includes a curved pipe portion 152, and the curved pipe portion 152 has an extended length in the horizontal direction. The curved pipe portion 152 can slow down the flow speed of the smoke oil and lengthen the flow path of the smoke oil, thereby preventing the smoke oil from flowing out of the top of the oil filling pipe 150. The extension direction of the curved pipe portion 152 can be parallel to the horizontal direction or intersect with the horizontal direction, without specific limitation.

[0044] See also Figure 1 , the elbow portion 152 can be located in the oil supply chamber 120. Compared with the oil storage chamber 110 and the suction nozzle 140, the oil supply chamber 120 has a relatively large space, which is more convenient for the setting of the elbow portion 152. Of course, the elbow portion 152 can also be located in the oil storage chamber 110 or the suction nozzle 140.

[0045] The number of the curved pipe portion 152 may be one. The number of the curved pipe portion 152 may also be multiple, and the multiple curved pipe portions 152 may be respectively disposed in the oil supply cavity 120 , the oil storage cavity 110 or the suction nozzle 140 .

[0046] The curved tube portion 152 may be substantially in the shape of a spiral, end-to-end S (eg, Figure 1 ), a V shape connected end to end, or a Z shape connected end to end. When there are multiple curved tube portions 152, the shapes of different curved tube portions 152 may be different. Of course, the shape of the curved tube portion 152 may also be an irregular shape, as long as it can achieve the effect of preventing the smoke oil from flowing to the top of the oil filling tube 150.

[0047] See also Figure 2 In one embodiment, the oil filling pipe 150 includes a main body 153 and a branch part 154. The main body 153 is sequentially arranged to penetrate the oil suction channel 142, the oil storage chamber 110 and the oil supply chamber 120. One end of the branch part 154 is connected and communicated with the main body 153, and the other end of the branch part 154 is open and located in the oil storage chamber 110. The smoke oil can flow into the oil storage chamber 110 through the branch part 154, which can improve the oil filling effect of the oil storage chamber 110 on the one hand, and prevent the smoke oil from further flowing out to the top of the main body 153 on the other hand.

[0048] See also Figure 2 , the branch portion 154 can be a straight tube. Of course, the branch portion 154 can also be a curved tube, without specific limitation. The number of the branch portions 154 can be one or more. The extension direction of the branch portion 154 can be parallel to the horizontal direction; the extension direction of the branch portion 154 can also intersect with the horizontal direction, and the end of the branch portion 154 away from the main body 153 can be tilted upward or downward.

[0049] See also Figure 2 A plurality of oil filling holes 151 are provided on the main body 153 and the branch part 154, so that the oil storage cavity 110 can have a better oil filling effect.

[0050] In some embodiments, the inner wall of the oil filling tube 150 is uneven, thereby slowing down the flow speed of the tobacco oil to prevent the tobacco oil from flowing to the top of the oil filling tube 150 .

[0051] The length of the oil injection hole 151 in the axial direction of the oil injection tube 150 is greater than the length of the oil injection hole 151 in the circumferential direction of the oil injection tube 150. Therefore, the oil injection hole 151 is set relatively long in the flow direction of the smoke oil, and the smoke oil in the oil injection hole 151 can quickly flow out of the oil injection tube 150 when passing through the oil injection hole 151, and is not easily guided by the oil injection tube 150 to continue to flow upward.

[0052] The distance between the top of the mist suction channel 141 and the top of the oil suction channel 142 is 1 to 10 mm. Therefore, the distance between the top of the mist suction channel 141 and the top of the oil suction channel 142 is appropriate, and the user's inhalation can drive the smoke oil to flow from the oil supply chamber 120 into the oil storage chamber 110 through the oil injection pipe 150. Further, the distance between the top of the mist suction channel 141 and the top of the oil suction channel 142 includes but is not limited to 1 to 6 mm, 1 to 5 mm, 3 to 5 mm, 4 to 8 mm, 2 to 10 mm, 1 to 4 mm, 5 to 10 mm, 3 to 6 mm, 5 to 6 mm, 3 to 7 mm, 1 to 8 mm, 7 to 10 mm, 4 to 6 mm or 8 to 9 mm. Furthermore, the length of the oil filling tube 150 includes but is not limited to 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm, etc.

[0053] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes a buffer cotton 160, which is arranged in the top of the oil filling tube 150 and is used to buffer the flow of gas. The buffer cotton 160 can slow down the drop speed of the air pressure in the oil filling tube 150, thereby slowing down the flow speed of the smoke oil, so that more smoke oil can flow into the oil storage chamber 110, and the effect of oil filling is better. It can be understood that the buffer cotton 160 can also prevent the smoke oil from flowing out of the oil filling tube 150.

[0054] See also Figure 1 and Figure 2 The electronic cigarette 10 of the present application includes an oil storage cotton 170, which is arranged in the oil storage cavity 110 and sleeved outside the atomizer assembly 130, and the oil injection tube 150 is passed through the oil storage cotton 170, and the oil storage cotton 170 covers a plurality of oil injection holes 151. The oil storage cotton 170 is used to provide oil to the atomizer assembly 130. The oil storage cotton 170 can absorb the oil flowing out of the oil injection hole 151 in time, which makes the oil injection effect better on the one hand, and makes it difficult for the oil to flow to the top of the oil injection tube 150 on the other hand.

[0055] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
