In some embodiments, the liquid suction unit 4 further comprises a liquid suction circular tube 10, the outer surface 9 of the liquid suction circular tube 10 is a circumferential surface, the outer contour of the liquid suction circular tube 10 is a cylindrical shape, the lumen of the liquid suction circular tube 10 is the atomizing channel 3, and the inner surface of the liquid suction circular tube 10 is the atomizing surface 6. Of course, the pipetting unit 4 can also comprise a pipette with a prismatic outer contour.

In some embodiments, the atomization surface 6 includes a plurality of concave unit surfaces 7 and a plurality of convex unit surfaces 17, the number of the concave unit surfaces 7 and the number of the convex unit surfaces 8 are both plural, the concave unit surfaces 7 and the convex unit surfaces 17 both extend along the axial direction of the liquid suction circular tube 10, the plurality of concave unit surfaces 7 are arranged at intervals in the circumferential direction of the liquid suction circular tube 10, and two ends of the convex unit surfaces 17 are respectively connected with two adjacent concave unit surfaces 7.

Referring to fig. 4, in some embodiments, the radial distance a of the concave unit faces 7 from the central axis 2 of the barrel 10 is greater than the radial distance B of the unit faces 8 of the projections 17 from the central axis 2.

In the radial direction of the liquid absorption circular tube 10, the distance from the protrusion unit surface 8 to the outer surface 9 of the liquid absorption circular tube 10 is C, wherein the value range of C is 1.1mm or more and A or less and 1.3mm or less, for example, the value of C is 1.1mm, 1.2mm or 1.3mm or the like, so that the maximum thickness of the tube wall of the liquid absorption circular tube 10 can be reasonably selected, and the liquid absorption circular tube 10 is ensured to have enough mechanical strength. In the radial direction of the liquid suction circular tube 10, the distance from the concave unit surface 7 to the outer surface 9 of the liquid suction circular tube 10 is D, wherein the value range of D is 0.9mm or more and B or less and 1.1mm or less, for example, the value of D is 0.9mm, 1.0mm or 1.1mm or the like, and in consideration of the diameter of the heating wire 18, a reasonable distance is ensured between the edge of the coil part 11 and the outer surface 9 of the liquid suction circular tube 10, so that excessive heat on the coil part 11 is prevented from being transferred to the outer surface 9 of the liquid suction circular tube 10, and the bad experience of scalding hands of a user is prevented.

Since the heating wire 18 includes the coil part 11 and the lead part 12, the edge of the coil part 11 is inscribed in the recessed cell face 7, and the lead part 12 is held at a set radial distance from the central axis 2. At least the following three benefits can be achieved:

firstly, the lead part 12 is partially embedded and hidden in the liquid suction circular tube 10, the liquid suction circular tube 10 completely wraps the lead part 12, and the exposed part does not influence the movement of the heating wire 18, so that the freedom degree of the lead part 12 is better limited, the liquid suction circular tube 10 plays a good role in supporting and protecting the lead part 12, and the heating wire 18 can be effectively prevented from falling off from the liquid suction circular tube 10.

Secondly, since the lead portion 12 is entirely covered with the liquid absorbing circular tube 10, the amount of smoke liquid infiltrated into the surface of the lead portion 12 is relatively large compared to the coil portion 11, and when the entire heating wire 18 generates heat, the amount of heat generated by the lead portion 12 per unit length is not higher than the amount of heat generated by the coil portion 11 per unit length for a certain period of time, and the total amount of smoke liquid heated by the lead portion 12 per unit length is higher than the total amount of smoke liquid heated by the coil portion 11 per unit length. Therefore, the operating temperature of the lead portion 12 is lower than the operating temperature of the coil portion 11, the atomization temperature of the liquid smoke corresponding to the lead portion 12 is lower than the atomization temperature of the liquid smoke corresponding to the coil portion 11, the mist atomized by the lead portion 12 overflows from the convex unit surface 8 to the atomization channel 3, the mist atomized by the coil portion 11 overflows from the concave unit surface 7 to the atomization channel 3, the tastes of the two types of mist will be different, that is, the liquid smoke can be atomized at different temperatures, and finally, the diversification of the tastes of the mist atomized by the atomization assembly 1 is realized.

Thirdly, when the heating wire 18 generates heat, because the amount of smoke liquid soaked on the surface of the lead part 12 is relatively large, the temperature of the coil part 11 is quickly raised relative to the lead part 12, and the coil part 11 reaches the initial atomization temperature at which the liquid smoke liquid is converted into gaseous smoke, so that the coil part 11 atomizes the smoke liquid in a short time, and the atomization assembly 1 is ensured to quickly form smoke.

Certainly, for the coil part 11 and the lead part 12 of the heating wire 18, the surfaces of the two parts are directly contacted with the smoke liquid, the temperature distribution of the surface of the whole heating wire 18 is uniform, the smoke liquid is prevented from bursting due to the overhigh local temperature of the heating wire 18, and the smoke liquid is also prevented from generating cracking reaction at the overhigh temperature position of the heating wire 18 to form toxic gases such as formaldehyde and the like.

In some embodiments, the liquid absorbing circular tube 10 may be made of a porous ceramic material, a plurality of capillary tubes are formed on the liquid absorbing circular tube 10 made of the porous ceramic material, an outer surface 9 of the liquid absorbing circular tube 10 is in contact with the smoke in the liquid storage unit (not shown), and the outer surface 9 of the liquid absorbing circular tube 10 is used for absorbing the smoke in the liquid storage unit.

The porosity of the porous ceramic material is 30% -60%, the optimal value is 35% -50%, the porosity cannot be too high, the risk of smoke liquid leakage is increased, and the supply of smoke liquid is difficult to meet due to too low degree.

In some embodiments, the radial distance from the heater 18 to the outer surface 9 of the barrel 10 is greater than the radial distance from the heater 18 to the atomizing surface 6. When the heater 18 generates heat in order to atomize the tobacco juice, because the difference of the heat loss among the heat transfer process that leads to apart from the difference, thereby make the temperature of the surface 9 of imbibition unit 4 be less than the temperature of atomizing face 6, ensure that the produced thermal most of heater 18 is used for atomizing the tobacco juice, avoid too much heat transfer to the surface 9 of imbibition unit 4 and lead to not being atomized the tobacco juice temperature rise in the stock solution unit, prevent the scalding hand phenomenon among the user's the use, improve the utilization ratio of heater 18 energy simultaneously.

Referring to fig. 5, the present invention further provides a method for manufacturing the atomizing assembly 1, which includes the following steps:

step one, providing a fixed column 13, wherein the fixed column 13 consists of two parts, the upper part is provided with a cover, and the lower part is provided with a main body;

step two, arranging a plurality of bulges 17 arranged at intervals along the circumferential direction on the outer circumferential surface of the fixed column 13, wherein each bulge 17 extends along the axial direction of the fixed column 13, and each bulge 17 is formed by the protrusion of the outer circumferential surface of the fixed column 13 towards the central axis of the fixed column 13;

placing the fixing column 13 sleeved with the heating unit 5 into a mold, performing slip casting, allowing ceramic slurry to enter the protrusion 17 and the surface of the heating unit 5, and solidifying the ceramic slurry to form a solid ceramic material after cooling;

step five, taking out the solidified ceramic material from the fixed column 13;

and step six, sintering the solidified ceramic material.

Through the above steps, the coil part of the ceramic material forming the liquid suction unit 4 and the heating unit 5 is finally embedded in the liquid suction unit 4 with the edge thereof being in contact with the inner surface of the liquid suction unit 4, and a part of the lead part of the heating unit 5 is hidden inside the liquid suction unit 4 by being wrapped, and the other part is exposed outside the liquid suction unit 4.

When the fixing post 13 with the heating unit 5 mounted thereon is placed in a mold and molded by slip casting, the ceramic material is cured and sintered to form the liquid absorbing unit 4, and at this time, a portion of the heating unit 5 contacting and abutting against the outer peripheral surface of the fixing post 13 forms the coil portion 11, and another portion of the heating unit 5 not contacting the outer peripheral surface of the fixing post 13 at a predetermined distance forms a portion of the lead portion 12.
