[0040] As Figures 1-7 shown, this embodiment provides an e-cigarette, including an atomization device and a power supply component for powering the atomization device.

[0041] The atomization device includes an atomization core 1 and an oil storage body 2. The atomization core 1 is installed in the oil storage body 2, and an oil storage chamber 27 is formed between the atomization core 1 and the inner wall of the oil storage body 2. The atomization core 1 includes an atomization tube 11. A plurality of porous hard wicking blocks 13 are arranged in the atomization tube 11. An atomization channel 14 for the smoke generated by heating to flow through is provided in the atomization tube 11. The atomization channel 14 is located between the plurality of porous hard wicking blocks 13. A heating element 15 is provided on one side of each porous hard wicking block 13 facing the atomization channel 14. An oil hole 111 corresponding to each porous hard wicking block 13 is formed in the atomization tube 11.

[0042] Among them, an atomization matrix is stored in the oil storage cavity 27. The atomization matrix is transmitted to the porous hard oil guiding block 13 in the atomizer core 1 through the oil passage hole 111, and after being heated by the heating element 15 on the porous hard oil guiding block 13, smoke is generated, and the smoke is discharged from the atomization channel 14 and inhaled by the user.

[0043] In some embodiments, one side of each porous hard oil guiding block 13 faces the tube wall of the atomization tube 11, and a heating element 15 is provided on the other side of each porous hard oil guiding block 13. The atomization channel 14 is formed between the side walls of the porous hard oil guiding block 13 where the heating element 15 is provided. The heating element 15 heats the e-liquid on the porous hard oil guiding block 13, and the generated smoke is discharged from the atomization channel 14 between the porous hard oil guiding blocks 13. In some examples, the porous hard oil guiding block 13 can be directly attached to the atomization tube 11. In other examples, a certain gap can also be left between the porous hard oil guiding block 13 and the atomization tube 11, and the present disclosure does not limit this.

[0044] Refer to Figure 5 , in some examples, the number of the porous hard oil guiding blocks 13 is two, and the two porous hard oil guiding blocks 13 are arranged oppositely. When the heating elements 15 on the two porous hard oil guiding blocks 13 act together, the heat is more concentrated, and the energy consumption required to reach the same temperature is smaller. In other examples, the number of the porous hard oil guiding blocks 13 can also be more, including but not limited to three, four, five, and so on.

[0045] In some embodiments, the atomizer core 1 further includes a fixing seat 12. Each porous hard oil guiding block 13 is arranged along the circumferential direction of the atomization tube 11, and one end of each porous hard oil guiding block 13 is installed on the fixing seat 12. A through hole 129 corresponding to the atomization channel 14 is also formed on the fixing seat 12, and the through hole 129 is communicated with the atomization channel 14; the fixing seat 12 is used to cooperate with the atomization tube 11 to limit the porous hard oil guiding block 13.

The limiting members 121 are arranged along the circumferential direction of the atomizing tube 11, and the porous hard oil guiding block 13 is clamped between adjacent limiting members 121. The limiting member 121 includes a body. The shape of one side wall of the body is adapted to the tube wall of the atomizing tube 11. At both ends of the other side wall of the body, clamping grooves 122 are respectively formed. The porous hard oil guiding block 13 is clamped in the clamping grooves 122. The porous hard oil guiding block 13 and the limiting member 121 jointly enclose a hollow columnar structure, and the atomizing channel 14 is formed in the hollow part. The clamping grooves 122 of adjacent limiting members 121 limit the porous hard oil guiding block 13 along the circumferential direction of the atomizing tube 11. At the same time, the porous hard oil guiding block 13 is clamped between the atomizing tube 11 and the fixed seat 12 up and down, thereby limiting the porous hard oil guiding block 13 along the length extension direction of the atomizing tube 11. At this time, the hollow channel surrounded by the porous hard oil guiding block 13 and the inner wall of the limiting member 121 serves as the atomizing channel 14.

One end of each porous hard oil guiding block 13 is inserted into the corresponding groove 124.

[0048] In some embodiments, an oil guiding cotton 16 is provided between the porous hard oil guiding block 13 and the tube wall of the atomizing tube 11. The oil guiding cotton 16 is used to buffer the oil supply speed from the oil storage cavity 27 to the porous hard oil guiding block 13 and prevent oil leakage caused by excessive oil supply.

[0049] In some embodiments, a pressure relief hole 112 is provided at the corresponding position of the atomizing tube 11 and the oil storage cavity 27. An elongated groove 123 communicated with the pressure relief hole 112 is provided on the fixed seat 12 and / or the atomizing tube 11. The pressure relief hole 112 communicates with the outside air through the elongated groove 123. The size of the elongated groove 123 only allows air flow to pass through. The pressure relief hole 112 and the elongated groove 123 are provided to balance the air pressure inside and outside the oil storage cavity 27 and prevent the situation of unsmooth oil supply caused by negative pressure.

[0050] In some embodiments, the porous hard oil guiding block 13 is made of quartz, and its porous structure has a good oil absorption effect. In some other embodiments, the porous hard oil guiding block 13 can be made of porous ceramic or mica material.

Specifically, the seal 3 is arranged at one end of the atomization tube 11 close to the mouthpiece 22, and the seal 23 is arranged between the base 24 and the housing 21. The seals 3 and 23 are used to prevent the e-liquid in the oil storage cavity 27 from leaking. The mouthpiece 22 has a suction port 221, and the base 24 is provided with an air inlet 241. The two ends of the atomization channel 14 communicate with the suction port 221 and the air inlet 241 respectively. The smoke generated in the atomization channel 14 is inhaled by the user through the suction port 221. Among them, the seal 23 is made of silica gel, plastic or latex.

[0052] In some embodiments, a magnet 25 and a conductive electrode 26 are provided on the base 24. The conductive electrode 26 is electrically connected to the heating element 15. The power supply assembly supplies power to the heating element 15 through the conductive electrode 26, and the power supply assembly and the atomization device are magnetically connected together through the magnet 25. In some other embodiments, other detachable or fixed connection methods can be adopted between the power supply assembly and the atomization device, and the present application does not limit this.

[0053] In some embodiments, the heating element 15 can be fixed on the porous hard oil guiding block 13 by means of printing, electroplating or pasting, etc. Each of the heating elements 15 is connected in parallel with each other. By adopting the parallel connection method, after some of the heating elements 15 are damaged, it will not affect the normal operation of the undamaged heating elements 15, and the stability is high. The heating element 15 is made of conductive metal, graphite, graphene or conductive nanofiber tubes.
