[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0024] like Figure 1-4As shown, an electronic cigarette includes a shell 1, in which an electronic atomization device is arranged, and the electronic atomization device is used to heat the atomized smoke oil. A suction nozzle 2 is arranged at one end of the shell 1, and the suction nozzle 2 is connected to the electronic atomization device for the user to smoke the electronic cigarette; an air inlet 3 is arranged at the other end of the shell 1, and the air inlet 3 is connected to the electronic atomization device. A microphone silicone 4 is fixedly installed in the shell 1, and a control board 5 and a battery 6 are installed on the microphone silicone 4. The battery 6 is limitedly connected to the shell 1, and the battery 6 and the electronic atomization device are electrically connected to the control board 5 respectively, for supplying power to the electronic cigarette. A start switch 7 is arranged on the control board 5, and the start switch 7 is connected to the air inlet 3. When the user draws on the electronic cigarette, he inhales through the mouthpiece 2, and the external air flows into the shell 1 through the air inlet 3; the start signal is triggered when the airflow flows through the start switch 7; the control board 5 controls the battery 6 to power the electronic atomization device, and the electronic atomization device works to heat the tobacco oil and atomize it into aerosol; after the external air enters the shell 1, it will flow into the electronic atomization device and mix with the atomized aerosol. Finally, the aerosol is inhaled by the user through the mouthpiece 2 along with the inhalation airflow, completing the inhalation process of the electronic cigarette.
[0025] The electronic atomization device includes an oil separator, and an upper seal 8 and a lower seal 9 are respectively provided at both ends of the oil separator, and the upper seal 8 and the lower seal 9 are respectively connected to the housing 1 in a limiting manner. The inner wall of the housing 1, the upper seal 8, the lower seal 9 and the outer wall of the oil separator form a relatively closed oil storage chamber 10, and the oil storage chamber 10 is used to hold the tobacco oil. An airway tube 11 is provided in the oil separator, and a heating core 12 is provided on the lower seal 9. The heating core 12 is electrically connected to the control board 5, and the heating core 12 is connected to one end of the airway tube 11, and the other end of the airway tube 11 is connected to the suction nozzle 2. The heating core 12 is connected to the oil storage chamber 10 through the oil separator. When the electronic cigarette is used, the tobacco oil in the oil storage chamber 10 can penetrate into the heating core 12 through the oil separator, so that the tobacco oil is heated and atomized into an aerosol through the heating core 12; then the atomized aerosol will flow into the airway tube 11 with the suction airflow, and finally flow out of the suction nozzle 2 to be inhaled by the user. The oil separator can prevent the smoke oil in the oil storage chamber 10 from flowing directly onto the heating core 12 , thereby preventing the problem of excessive smoke oil and leakage of the heating core 12 .
[0026] like Figure 3As shown, specifically, the oil separator device includes an oil separator tube 13 made of stainless steel, and the two ends of the oil separator tube 13 are respectively plugged and fixed with the upper seal 8 and the lower seal 9. The upper seal 8 and the lower seal 9 are respectively made of silicone material. Since silicone has a certain elasticity, the oil separator tube 13 can be sealed and connected with the upper seal 8 and the lower seal 9 after being inserted into the upper seal 8 and the lower seal 9. An oil storage cotton 14 is arranged in the oil separator tube 13, and the oil storage cotton 14 is sleeved on the periphery of the airway tube 11, and the oil storage cotton 14 is in contact with the outer wall of the airway tube 11; the oil storage cotton 14 is used to absorb the smoke oil to prevent the smoke oil from flowing freely in the oil separator tube 13, thereby reducing the possibility of smoke oil leakage. The oil separator 13 is provided with an oil hole 131, and the smoke oil in the oil storage chamber 10 can flow into the oil separator 13 through the oil hole 131, and then enter the oil storage cotton 14; the heating core 12 is provided with an oil inlet hole 121, and the oil inlet hole 121 is connected with the oil storage cotton 14, and the horizontal position of the oil hole 131 is lower than the horizontal position of the oil inlet hole 121; the oil hole 131 is arranged below the oil inlet hole 121, which can reduce the smoke oil from flowing into the heating core 12 through the oil inlet hole 121, thereby reducing the possibility of the smoke oil leaking from the heating core 12. When inhaling, the smoke oil in the oil storage chamber 10 flows into the oil storage cotton 14 through the oil hole 131, and then flows into the heating core 12 through the oil inlet hole 121. The heating core 12 heats up and atomizes the smoke oil into aerosol for the user to inhale.
[0027] A pressure relief airway 15 is provided on the upper seal 8, and a ventilation airway 16 is provided between the inner wall of the oil separator 13 and the outer wall of the oil storage cotton 14. One end of the pressure relief airway 15 is connected to the inner cavity of the airway tube 11, and the other end is connected to the ventilation airway 16, and the ventilation airway 16 is connected to the oil hole 131. After the electronic cigarette is used for a period of time, as the oil in the oil storage cavity 10 and the oil storage cotton 14 gradually decreases, negative pressure will be generated in the oil storage cavity 10 and the oil storage cotton 14, which will not only make the oil flow unsmooth and cause the smoking taste to deteriorate, but also easily cause the oil to leak due to the negative pressure in the inner cavity. By setting up the ventilation airway 16 and the pressure relief airway 15, it is convenient to replenish air and relieve pressure on the oil storage cotton 14 and the oil storage chamber 10; when negative pressure is generated in the oil storage chamber 10 or the oil storage cotton 14, the external air will flow into the airway tube 11 through the suction nozzle 2, and then flow into the pressure relief airway 15 and the ventilation airway 16, and then flow into the oil storage cotton 14, or flow into the oil storage chamber 10 through the oil hole 131, so that the internal and external air pressures of the oil storage chamber 10 and the oil storage cotton 14 are balanced, thereby achieving the purpose of pressure relief and air replenishment.
[0028] like Figure 4As shown, in this embodiment, the pressure relief airway 15 includes a first annular groove 151, a connecting airway 152 and a second annular groove 153 respectively arranged in the upper seal 8, and a pressure relief hole 111 is provided on the airway tube 11, the pressure relief hole 111 is communicated with the first annular groove 151, the connecting airway 152 is communicated with the first annular groove 151 and the second annular groove 153 respectively, and the second annular groove 153 is communicated with the oil storage cotton 14. After the electronic cigarette is assembled, the airway tube 11 is inserted into the upper seal 8, so that the outer side wall of the airway tube 11 and the first annular groove 151 and the second annular groove 153 respectively form two independent annular cavities. After negative pressure is generated in the oil storage cotton 14 or the oil storage chamber 10, the external air flows into the airway tube 11 through the suction nozzle 2, and then flows into the first annular groove 151, the connecting airway 152, the second annular groove 153 and the ventilation airway 16 in sequence through the pressure relief hole 111, and then flows into the oil storage cotton 14, or flows into the oil storage chamber 10 through the oil hole 131, so that the internal and external air pressures of the oil storage chamber 10 and the oil storage cotton 14 are balanced, and pressure relief and air replenishment are achieved. By providing the first annular groove 151 and the second annular groove 153, the external airflow can flow into the oil storage cotton 14 or the oil storage chamber 10 evenly, improving the stability of the pressure relief and air replenishment process.
[0029] like Figure 2 As shown, the lower sealing member 9 is provided with an air inlet duct 17, one end of the air inlet duct 17 is an air inlet end 171, and the other end is an air outlet end 172. The air inlet end 171 is connected to the air inlet hole 3, and the air outlet end 172 is connected to the heating core 12. The horizontal position of the air inlet end 171 is higher than the horizontal position of the air outlet end 172, and the air outlet end 172 is connected to the heating core 12. The air inlet duct 17 is provided so that the heating core 12 can be connected to the air inlet hole 3, so that the external air flow can flow into the heating core 12 and mix with the aerosol; the air outlet end 172 in the air inlet duct 17 is set to be lower than the air inlet end 171, so as to prevent the smoke oil leaking from the heating core 12 from flowing down to the battery 6 and the control board 5. The air inlet duct 17 is configured as a "high-in, low-out" structure. Even if some of the smoke oil leaks from the heating core 12, the leaked smoke oil will not flow into the electrical components below the atomizer, thereby preventing the smoke oil from flowing out of the electronic cigarette or the smoke oil from corroding the control board 5 or the start switch 7. This can extend the service life of the electronic cigarette and improve the user's usage experience.
[0030] In this embodiment, there are two air inlet passages 17, and the two air inlet passages 17 are symmetrically distributed along the central axis of the lower sealing member 9, so that the air inlet passages 17 are in an "inverted eight" shape as a whole. In other embodiments, the air inlet passages 17 can also be any other number.
[0031] In order to further reduce the possibility of oil leakage, an oil-absorbing cotton 18 is provided on the lower sealing member 9. The oil-absorbing cotton 18 is arranged below the air inlet duct 17 and directly below the heating core 12 to absorb the oil dropped from the heating core 12. When oil leaks from the heating core 12, the leaked oil will fall onto the oil-absorbing cotton 18 due to its own gravity and be absorbed by the oil-absorbing cotton 18, thereby preventing the oil from flowing from the air inlet duct 17 to the battery 6 and the control panel below.
[0032] like Figure 1 As shown, an oil filling hole is provided on the side wall of the housing 1, and the oil filling hole is connected with the oil storage chamber 10, so that smoke oil can be easily injected into the oil storage chamber 10 through the oil filling hole. A detachable oil filling sealing plug 19 is provided on the oil filling hole; when filling oil, the oil filling sealing plug 19 is taken out from the oil filling hole; after the oil filling is completed, the oil filling sealing plug 19 is used to cover the oil filling hole to prevent the smoke oil from leaking.
[0033] Working principle:
[0034] During the electronic cigarette inhalation process, the user inhales through the mouthpiece 2, and the external air flows into the housing 1 through the air inlet 3. Part of the airflow passes through the start switch 7 to trigger the start signal. The oil in the oil storage chamber 10 flows into the oil storage cotton 14 through the oil hole 131, and then flows into the heating core 12 through the oil inlet 121; the control board 5 controls the battery 6 to supply power to the heating core 12, and the heating core 12 works to heat the oil and atomize it into aerosol. After passing through the air inlet 3, the inhaled airflow flows into the gap between the battery 6 and the housing 1, and then flows into the air inlet duct 17, and then flows into the heating core 12 through the air inlet duct 17 to mix with the aerosol. The mixed aerosol then flows into the mouthpiece 2 through the airway tube 11, and is finally inhaled by the user, completing the electronic cigarette inhalation process.
[0035] As the oil in the oil storage cotton 14 and the oil storage chamber 10 gradually decreases, negative pressure will be generated therein; at this time, the external air will flow into the airway tube 11 through the suction nozzle 2, and then flow into the first annular groove 151, the connecting airway 152, the second annular groove 153 and the ventilation airway 16 in sequence through the pressure relief hole 111, and then flow into the oil storage cotton 14, or flow into the oil storage chamber 10 through the oil hole 131, so that the internal and external air pressures of the oil storage chamber 10 and the oil storage cotton 14 are balanced, pressure relief and air replenishment are achieved, the stability of the electronic cigarette is improved, and the possibility of oil leakage is reduced.
[0036] If some of the smoke oil leaks through the heating core 12 , it can only fall onto the oil-absorbing cotton 18 and be absorbed by the oil-absorbing cotton 18 , and the smoke oil will not leak onto the control board 5 or flow out of the air inlet 3 .
[0037] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
