In other examples, the atomizer core 50 may further include an oil guide body 53. The atomizer core 50 is arranged in the oil storage tank body 20. The smoke oil in the oil storage tank body 20 flows into the atomizer core 50 and is atomized by the atomizer core 50. The atomized smoke enters the smoking port 25 through the smoke exhaust channel 23 for the user to inhale. The atomizer component is electrically connected to the power supply component 70. The power supply component 70 is installed at the bottom of the oil storage tank body 20. The battery 71 is used to supply power to the atomizer core 50. The airflow sensor controls the connection or disconnection of the circuit between the battery 71 and the heating element 54 through airflow sensing. The battery core is electrically connected to the heating element and the airflow sensor respectively. It should be noted that the electrical connection can be directly connected or indirectly connected, including but not limited to through a control circuit board, pins, wires, etc.

[0053] In some instances, an oil storage cavity 21 is formed in the oil storage tank body 20, and the oil storage cavity 21 is used to store tobacco oil. A smoke guide pipe 22 is formed in the oil storage tank body 20, and the smoke guide pipe 22 is connected from top to bottom. A smoke exhaust channel 23 is formed in the smoke guide pipe 22, and the oil storage cavity 21 surrounds the periphery of the smoke guide pipe 22; one end of the oil storage tank body 20 is provided with a smoking nozzle 24, and the smoking nozzle 24 is provided with a smoking port 25, and the smoking port 25 is communicated with the smoke exhaust channel 23, and the smoke generated by the atomization core 50 enters the smoking port through the smoke exhaust channel 23 for the user to inhale; a cigarette holder cap 10 is provided on the smoking nozzle 24, which can be covered when the electronic cigarette is not in use, which is more hygienic; the other end of the oil storage tank body 20 is provided with an opening, and a sealing seat 40 is provided at the opening for sealing to prevent oil leakage.

[0054] Reference Figure 1-5 The atomizer core 50 is installed in the oil storage tank body 20, and the atomizer core 50 includes a porous hard sheet 51, a heating element 54 is provided on one side of the porous hard sheet 51, and a porous flexible sheet 52 is provided on the other side of the porous hard sheet 51, and at least one end of the porous hard sheet 51 and / or the porous flexible sheet 52 is exposed relative to the oil storage chamber 21; it should be noted that the exposure here means that the end of the porous hard sheet 51 and / or the porous flexible sheet 52 is directly or indirectly connected to the oil storage chamber 21, and the smoke oil in the oil storage chamber 21 can be directly or indirectly transferred to the porous hard sheet 51 and / or the porous flexible sheet 52. In some examples, only at least one end of the porous flexible sheet 52 is exposed relative to the oil storage chamber 21, and the oil absorbed by the porous flexible sheet 52 is transferred to the porous hard sheet 51 for absorption, wherein one end of the porous flexible sheet 52 may be exposed relative to the oil storage chamber 21, or both ends of the porous flexible sheet 52 may be exposed relative to the oil storage chamber 21. In other examples, at least one end of the porous hard sheet 51 and the porous flexible sheet 52 are both exposed relative to the oil storage chamber 21, and the tobacco oil is supplied to the porous hard sheet 51 and the porous flexible sheet 52 at the same time, so as to ensure sufficient oil supply and prevent dry burning, wherein one end of the porous hard sheet 51 and the porous flexible sheet 52 may be exposed relative to the oil storage chamber 21, or both ends of the porous hard sheet 51 and the porous flexible sheet 52 may be exposed relative to the oil storage chamber 21.

[0055] The porous hard sheet and the porous flexible sheet designed in the atomizer core 50 are used to absorb oil, which can meet the demand for oil absorption and produce a sufficiently large amount of smoke without dry burning. At the same time, the space occupied is small, which can make the electronic cigarette design thinner and lighter.

[0056] An oil guide 53 is provided in the oil storage cavity 21, and the oil guide 53 is located at the end of the porous hard sheet 51 and / or the porous flexible sheet 52 exposed relative to the oil storage cavity 21. The oil guide 53 can reduce the impact force of the incoming oil and avoid the problem of oil leakage caused by large incoming oil.

[0057] The porous hard sheet 51 is a porous ceramic sheet or a porous mica sheet, etc., which has a certain hardness and a porous structure capable of absorbing oil. The heating element 54 is a heating wire printed or etched and embedded on the porous hard sheet 51. The heating wire is electrically connected to the battery core 71 through a wire. The heating wire conducts electricity and generates heat, which can heat and atomize the tobacco oil on the porous hard sheet 51. The oil guide body 53 and the porous flexible sheet 52 can be made of cotton or oil-absorbing fiber. Specifically, for example, the porous flexible sheet 52 is a sheet structure made of H7 cotton, and the oil guide body 53 is made of special fiber cotton. The porous flexible sheet 52 made of H7 cotton abuts or is fixed on the side of the porous hard sheet 51. The ends of both sides of the porous hard sheet 51 and the porous flexible sheet 52 are respectively exposed relative to the oil storage chamber 21, and the oil guide body 53 abuts on the exposed ends of the porous hard sheet 51 and / or the porous flexible sheet 52.

[0058] Since the ends of the porous hard sheet 51 and the porous flexible sheet 52 have limited oil absorption capacity, if the two are allowed to directly contact the oil storage chamber 21, oil leakage is likely to occur. Therefore, an oil guide body 53 is provided to buffer the smoke oil in the oil storage chamber 21. At the same time, the porosity of the porous flexible sheet 52 is greater than that of the oil guide body 53. The larger the porosity, the better the water and oil absorption performance. The smoke oil can be smoothly transferred from the oil guide body 53 to the porous flexible sheet 52; the oil guide body 53 transfers the smoke oil in the oil storage chamber 21 to the two ends of the porous hard sheet 51 and the porous flexible sheet 52. After absorbing the smoke oil, the porous flexible sheet 52 further supplies oil to the porous hard sheet 51, thereby realizing three-sided oil supply to the porous hard sheet 51, and the oil supply efficiency is higher. At the same time, compared with the traditional atomization core 50, the sheet-like structure of the porous hard sheet 51 and the porous flexible sheet 52 saves more space, so that the electronic cigarette can be made thinner, thereby improving the user experience.

[0059] Reference Figure 6-9 In some examples, the base 60 is used to install the atomizer core 50, and the base 60 has a receiving space 604, the porous flexible sheet 52 and the porous hard sheet 51 are installed in the receiving space 604, and the base 60 has a notch 605 that allows the receiving space 604 to communicate with the oil storage chamber 21, and the notch 605 is a "U"-shaped structure (such as Figure 8 As shown), in other embodiments, the shape of the notch 605 is set as needed, as long as the accommodating space 604 is connected to the oil storage chamber 21, and the notch 605 corresponds to one end of the porous flexible sheet 52 and the porous hard sheet 51 exposed in the oil storage chamber 21.

[0062] In some other examples, the recess 607 may be formed on the porous hard sheet 51 . In some other embodiments, the recess 607 may be formed on both the porous hard sheet 51 and the first protruding portion 602 .

[0063] In some other examples, a through hole 608 is formed on the wall of the base 60 opposite to the heating element 54, and a sealing seat 40 is provided on the outer cover of the base 60. The sealing seat 40 covers the through hole 608, and the area formed by the through hole 608 serves as a second gap channel (see Figure 5 ), the second gap channel is connected to the first gap channel and at least partially overlaps. Specifically, the through hole 608 is provided on the first protruding portion 602, and the provision of the through hole 608 increases the size of the first gap channel, further increases the air flow, and thus increases the amount of smoke that can be inhaled by the user.

[0064] In some examples, a distance is left between the porous hard sheet 51 and the porous flexible sheet 52 and the through-holes 606 to prevent the porous hard sheet 51 and the porous flexible sheet 52 from blocking the through-holes 606 .

[0065] In some embodiments, the base 60 is formed with a notch 609 (eg, Figure 7 As shown), the entire base 60 is in a "convex" shape, and the oil guide body 53 is arranged at the notches 609 on both sides of the "convex" shape, so that the oil guide body 53 is installed more stably.

The sealing seat 40 has a connecting hole 41 connected to the smoke guide pipe 22, and the connecting hole 41 is communicated with the through-hole 606. The sealing seat 40 is provided with an oil inlet hole 42 at a position corresponding to the oil guide body 53, and the oil guide body 53 abuts against the oil inlet hole 42 to connect the oil storage chamber 21 and the atomization core 50.

[0067] Among them, the sealing seat 40 plays the role of sealing the bottom opening of the oil storage tank body 20. At the same time, holes are opened at the positions corresponding to the oil guide body 53 and the smoke guide tube 22 to ensure the smooth flow of the electronic cigarette oil path and airway. The connecting hole 41 is used to connect the smoke guide tube 22 above the sealing seat 40 and the through air hole 606 below the sealing seat 40. At the same time, the smoke oil in the oil storage chamber 21 flows to the oil guide body 53 through the oil inlet hole 42, and then is transferred to the atomization core 50 through the oil guide body 53.

[0068] Reference Figure 4 and Figure 6 An elongated groove 610 is provided at the joint between the base 601 and the oil-conducting body 53. The elongated groove 610 is communicated with the through-hole 606. The size of the elongated groove 610 only allows airflow to pass through. Specifically, the depth and width of the elongated groove 610 are both less than 1 mm. The elongated groove 610 is used for ventilation to prevent the negative pressure from causing the oil-conducting body 53 to deform and affect the oil-blocking effect. The elongated groove 610 is set to a slender structure, which prevents the smoke oil on the oil-conducting body 53 from flowing into the elongated groove 610 while ventilating.
