Preferably, the housing 11 is made of a transparent or semitransparent material, so that a user can conveniently check the oil remaining in the oil storage chamber 14. The base 13 is installed at one end of the housing 11 and closes an opening at one end of the housing 11. The base 13 includes a first electrode holder 131, a first insulator 133, and a first electrode column 132. The first electrode holder 131 is of a columnar structure, a first mounting hole is formed in the first electrode holder along the axial direction, and the outer side wall of the first mounting hole is turned outwards to form a support ring. An opening at one end of the shell 11 is sleeved on the periphery of the first electrode holder 131, and the end surface of the opening 161 is abutted to the support ring to realize positioning and supporting. In practical applications, the housing 11 and the first electrode holder 131 may be fixedly connected by interference fit or screw connection.

Further, the first insulating member 133 is sleeved on the first electrode column 132 and penetrates through the first mounting hole. The first insulating member 133 is made of an elastic and electrically insulating material, and is elastically abutted against the outer periphery of the first electrode column 132 and the inner wall of the first mounting hole, so as to fix the first electrode column 132 to the first electrode holder 131. Preferably, the first electrode holder 131 passes through the first mounting hole, and has one end extending into the housing 11 and the other end exposed outside the housing 11. In practical applications, the blind hole 16 may be disposed in the first electrode holder 131, the first insulating member 133, or the first electrode column 132, which may also be disposed between the first electrode holder 131 and the first insulating member 133, and between the first insulating member 133 and the first electrode column 132.

In the present embodiment, as shown in fig. 1, the atomizing assembly 12 includes an atomizing pipe, a heating member, and an oil guide member. The atomizing pipe is installed in the casing 11 along the axial direction of the casing 11, and an annular oil storage chamber 14 is formed between the outer side wall of the atomizing pipe and the inner side wall of the casing 11. The heating element and the oil guide element are arranged in the atomizing pipe and form an atomizing channel 15 which is independent from the oil storage cavity 14 with a channel in the atomizing pipe. In practical application, the heating member can be around rolling up in lead oily piece, lead oily piece and run through perpendicularly the atomizing pipe, and both ends stretch into in the oil storage chamber 14 to absorb the fluid in the oil storage chamber 14. The heating member also can be coaxial embedding lead in the oil spare, and lead in the oil spare is coaxial to be plugged into the atomizing pipe to the tobacco tar in the oil storage chamber 14 is absorbed through the oilhole of crossing of atomizing pipe lateral wall. One end of the heating element is electrically connected with the first electrode column 132, and the other end of the heating element is electrically connected with the first electrode holder 131, and is electrically connected with the power supply device 2 through the base 13 to obtain power supply.

Further, the atomization tube may be integrally formed with the housing 11, or may be mounted in the housing 11 by a fastener or a seal. Preferably, one end of the atomization tube passes through the first sealing element and is communicated with the suction port of the shell 11, and the other end of the atomization tube passes through the second sealing element 18 and is communicated to the blind hole 16, and the atomization tube is fastened in the shell 11 through elastic abutment between the first sealing element and the inner side wall of the shell 11 and the second sealing element 18.

Since the base 13 is provided with the first air intake hole 163 for intake air and the blind hole 16, the atomizing pipe communicates with the blind hole 16 to obtain air necessary for atomization. In practical applications, one end of the atomization tube may be directly connected with the open end 161 of the blind hole 16 in a sealing manner, or may not be connected with the open end 161 of the blind hole 16. Preferably, a liquid storage cavity 17 is further arranged between the atomizing pipe and the open end 161 of the blind hole 16. The blind holes 16 of the atomizing pipes are communicated with each other through the liquid storage cavity 17. The reservoir 17 is used for storing oil or condensate flowing out of the atomizing passage 15, so as to prevent the liquid flowing out of the atomizing pipe from directly flowing into the open end 161 of the blind hole 16 and further seeping out of the atomizing device 1 and entering the power supply device 2.

Further, as shown in fig. 6, the second sealing member 18 is located between the atomizing pipe and the open end 161 of the blind hole 16, and the second sealing member 18 is provided with a third mounting hole for mounting the atomizing pipe. And one end of the third mounting hole is connected with the atomizing pipe so as to fasten the atomizing pipe and communicate with the atomizing pipe. For example, one end of the atomization tube may be sleeved on the periphery of the third mounting hole, or may extend into the third mounting hole. The other end of the third mounting hole is communicated with the open end 161 of the blind hole 16, and the open end 161 of the blind hole 16 may be flush with the end surface of the third mounting hole, or may slightly extend into the third mounting hole, so as to ensure smooth circulation of air flow. Thus, the space between the second sealing element 18 and the base 13 is surrounded to form the oil storage chamber 14, the oil in the atomizing pipe flows into the third mounting hole under the action of gravity and then flows into the liquid storage chamber 17 from the third mounting hole, and therefore the probability of the oil permeating into the air inlet channel 21 can be reduced.

Preferably, the end of the third mounting hole, which is communicated with the blind hole 16, is tapered, the inner diameter of the third mounting hole gradually increases along the direction close to the base 13, and the maximum inner diameter of the third mounting hole is larger than the inner diameter of the open end 161 of the blind hole 16. The inner wall of third mounting hole one end is the inclined plane of outside expansion like this, is followed by the fluid that the atomizing pipe flowed into the third mounting hole the inner wall of third mounting hole is followed again the inclined plane flows in the stock solution chamber 17 to the probability in fluid inflow blind hole 16 has been reduced.

Further, the liquid storage cavity 17 is filled with an oil absorption member, and the oil absorption member may be made of porous material, such as oil absorption cotton, foam or porous ceramic. The oil liquid accumulated in the liquid storage cavity 17 is further absorbed by the oil absorption piece, so that the liquid storage capacity of the liquid storage cavity 17 is improved, and the oil liquid is effectively prevented from flowing or seeping in the liquid storage cavity 17.

The first air intake holes 163 are disposed on the sidewall of the second post 1322 and communicate with the opening end 161. By providing the first air inlet opening 163 in the side wall of the blind hole 16, air is admitted to the bottom of the atomizer 1, and condensate is prevented from flowing straight into the power supply unit 2 along with the air inlet channel 21. The first air intake holes 163 may be one, two or more. Preferably, the number of the first air intake holes 163 is four, and the four first air intake holes 163 are uniformly distributed along the circumferential direction of the second cylinder 1322 to achieve uniform air intake.

Preferably, the second cylinder 1322 has an outer diameter larger than that of the first cylinder 1321, so that the depth of the first air inlet hole 163 is increased, thereby delaying the leakage of oil when the oil flows into the blind hole 16 from the atomizing passage 15, and preventing the oil from directly flowing into the power supply unit 2. In addition, since the end surface of the second column 1322 facing away from the first column 1321 is exposed outside the housing 11 for the electrical connection of the atomizing device 1, the contact area can be increased, and thus a more stable electrical contact can be formed.

Further, a groove 1311 is formed at one end of the first electrode holder 131 exposed out of the housing 11, and a fourth mounting hole communicated with the first mounting hole is formed in a bottom wall of the groove 1311.
