The heating assembly 130 includes a liquid conducting body 131 and a heating element 132. The liquid conducting body 131 is located on the opening end 121, and the conducting body 131 has a liquid absorbing surface 131a facing an inside of the liquid storage cavity 122, and has an atomizing surface 131b located outside of the liquid storage cavity 122, the liquid conducting body 131 conducts the atomizing liquid in the liquid storage cavity 122 to the atomizing surface 131b. The heating element 132 is formed on the atomizing surface 131b, and the heating element 132 atomizes the atomizing liquid conducted to the atomizing surface 131b, so as to obtain an atomized gas for smoking.
In addition, the liquid absorbing surface 131a defines a recess 131c, and an minimum conduction distance of the atomizing liquid from a bottom wall of the recess 131c to the atomizing surface 131b is less than a minimum conduction distance of the atomizing liquid from the liquid absorbing surface 131b to the atomizing surface 131b. In the illustrated embodiment, the liquid conducting body 131 can be of any shape. The liquid absorbing surface 131a and the atomizing surface 131b can be a flat surface or a curved surface. The liquid absorbing surface 131a and the atomizing surface 131b can be arranged in parallel, or form a certain angle. When no recess 131c is formed on the liquid absorbing surface 131a, the atomizing liquid has a minimum conduction distance, and when the recess 131c is defined on the liquid absorbing surface 131a, another minimum conduction distance is formed between an bottom wall of the recess 131c and the atomizing surface 131b. Since the minimum conduction distance of the atomizing liquid from the bottom wall of the recess 131c to the atomizing surface 131b is further less than the minimum conduction distance of the atomizing liquid from the liquid absorbing surface 131a to the atomizing surface 131b, the atomizing liquid can enter the recess 131c quickly and travel along the a shortest traveling path formed between the bottom wall of the recess 131c and the atomizing surface 131b, such that a conduction distance of the atomizing liquid is reduced, the resistance subjected during the flow of the atomizing liquid is reduced, and the conduction efficiency of the liquid conducting body 131 is improved. Meanwhile, compared with the solution in which the recess 131c is not formed on the liquid absorbing surface 131a, the liquid conducting body 131 of this solution has a greater contact area with the atomizing liquid, which facilitates the conduction of the atomizing liquid, and also increases the volume of the liquid storage cavity 122, so as to increase the amount of liquid stored in the liquid storage cavity 122.

In one of the embodiments, the recess 131c extends along a direction from the liquid absorbing surface 131a to the atomizing surface 131b. The bottom wall of the recess 131c can be a curved surface, or a planar surface that is parallel to the atomizing surface 131b, or forms an angle with the atomizing surface 131b, or any other shape. Regardless of the shape of the bottom wall of the recess 131c, the recess 131c extends along a linear direction perpendicular to the atomizing surface 131b and approaches the atomizing surface 131b. In this case, a flowing path of the atomizing liquid along the recess 131c is a straight line, therefore this configuration can prevent the problem of a relatively large resistance of the atomizing liquid caused by a longer flowing path of the atomizing liquid along the recess 131c when the recess 131c is curved, so as to shorten the flowing path of the atomizing liquid along the recess 131c, reduce the resistance to the atomizing liquid, and improve a transfer efficiency of the atomizing liquid. Meanwhile, a depth d2 of the recess 131c is a distance from the bottom wall of the recess 131c to the liquid absorbing surface 131a, and the minimum conduction distance d3 from the bottom wall of the recess 131c to the liquid absorbing surface is a distance from a position at the bottom wall of the recess 131c farthest from the liquid absorbing surface 131a to the atomizing surface 131b. When the atomizing liquid enters the recess 131c, the atomizing liquid will be conducted from the position at the bottom wall of the recess 131c farthest from the liquid absorbing surface 131a to the atomizing surface 131b.
Additionally, in one of the embodiments, the minimum conduction distance between the bottom wall of the recess 131c and the atomizing 131b is less than the depth of the recess 131c, in this way, the minimum conduction distance d3 between the bottom wall of the recess 131c is further less than the depth d2 of the recess 131c. When the thickness of the liquid conducting body 131 is constant, the minimum conduction distance d3 can be reduced via increasing the depth d2 of the recess 131c, such that the atomizing liquid can flow to a position at the bottom wall of the recess 131c that nearest to the atomizing surface 131b as soon as possible, and the atomizing liquid can be conducted through the minimum conduction distance d3 between the bottom wall of the recess 131c and the atomizing surface 131b to the atomizing surface 131b under a relatively less resistance, so as to improve the conduction efficiency of the liquid conducting body 131.
In one of the embodiments, a cross-sectional area of the recess gradually decreases along a direction from the liquid absorbing surface 131a to the atomizing surface 131b, such that the recess 131c can have a relatively greater opening at the liquid absorbing surface 131a, and the atomizing liquid can enter the recess 131c smoothly without forming a film at the opening of the recess 131c to block the atomizing liquid from flowing along the recess 131c. The recess 131c can have a step shape, a cone shape, or a frustum shape.
In one of the embodiments, the bottom wall of the recess 131c is parallel to the atomizing surface 131b. In this case, the minimum conduction distance between the bottom wall of the recess 131c and the atomizing surface 131b is the distance between the bottom wall of the recess 131c and the atomizing surface 131b. The atomizing liquid can be conducted to the atomizing surface 131b with the minimum conduction distance from any position at the bottom wall of the recess 131c, thus the conduction efficiency of the liquid conducting body 131 is further improved.
In one of the embodiments, the liquid conducting body 131 is a porous body. The liquid conducting body 131 defines a plurality of micropores, and the atomizing liquid can flow along the micropores and be conducted to the atomizing surface 131b. Pore size of the micropores can be adjusted according to the type of the atomizing liquid, for example, if the viscosity of the atomizing liquid is large, a liquid conducting body 131 with greater pore size can be selected, such that the conduction efficiency of the liquid conducting body 131 is moderate. Moreover, in one of the embodiments, the liquid conducting body 131 is a porous ceramic.
In one of the embodiments, the heating element 132 can be a heating coat, a heating circuit, a heating chip, or a heating net. The heating coat can be coated on the atomizing surface 131b. The heating circuit can be plated on the atomizing surface 131b. The heating chip and the heating net can be mounted on the atomizing surface 131b via other auxiliary mounting means. The heating element 132 has a thin layer structure aligned with the atomizing surface 131b, so as to uniformly heat the atomizing surface 131b, such that the temperature for atomizing is consistent to avoid greater atomized particles caused by local lower temperatures, the atomized particles are uniform and the taste of the electronic cigarette is improved. Meanwhile, the heating element 132 has a greater contact area with the atomizing liquid, so as to improve the atomization efficiency.

Additionally, in one of the embodiments, a side of the liquid conducting body 131 adjacent to the liquid absorbing surface 131a extends into the opening of the liquid reservoir 120. The sealing element 133 includes a sealing body 133a, which is sleeved on a side surface 131d of the liquid conducting body 131, and abuts against an inner wall of the liquid reservoir 120, so as to seal a gap between the liquid conducting body 131 and the inner wall of the liquid reservoir 120.
In one of the embodiments, the sealing element 133 further includes a first latching portion 133b and a second latching portion 133c. The first latching portion 133b is formed on an end of the sealing body 133a adjacent to the liquid absorption 131b, and the second latching portion 133c is formed on an end of the sealing body 133a adjacent to the atomizing surface 131b. The first latching portion 133b and the second latching portion 133c are latched to both ends of the liquid conducting body 131, respectively, so as to limit the relative mounting of the liquid conducting body 131 and the sealing element 133, which not only facilitates the mounting of the liquid conducting body 131 and the sealing element 133, but also prevents the liquid conducting body 131 from separating with the sealing element 133 to ensure an effective sealing of the sealing body 133a. Moreover, in one of the embodiments, the first latching portion 133b and the second latching portion 133c are both formed on an inner wall of the sealing body 133a. A boss portion 131e is formed on the side wall 131d of the liquid conducting body 131, the first latching portion 133b abuts against the boss portion 131e, and the second latching portion 133c abuts against the atomizing surface 131b, so as to limit the position of the liquid conducting body 131.
In one of the embodiments, the sealing element 133 further includes a third latching portion 133d. The third latching portion 133d is formed on an end of an outer wall of the sealing body 133a adjacent to the atomizing surface 131b, and the third latching portion 133d abuts against the end surface of the opening end 121 of the liquid reservoir 120. The configuration of the third latching portion 133d can limit the mounting of the heating assembly 130 at the opening of the liquid reservoir 120, so as to prevent the sealing element 133 and the liquid conducting body 131 from extending into the opening too deep, and to facilitate the mounting of the heating assembly 130 and the liquid reservoir 120.
In one of the embodiments, the sealing element 133 further includes a sealing ring 133e formed on an end of an outer wall of the sealing body 133a adjacent to the liquid absorbing surface. The sealing ring 133e can firmly abut against an inner wall of the liquid reservoir 120, so as to improve the sealing between the liquid conducting body 131 and the liquid reservoir 120.
In one of the embodiments, the sealing element 133 is an integrated structure. The sealing body 133a, the first latching portion 133d, the second latching portion 133c, the third latching portion 133d and the sealing ring 133e are integrally formed. The sealing element 133 can be made of silicone material, or other materials with sealing and thermal insulation features. The sealing element 133 enwraps the liquid conducting body 131, so as to reduce the unnecessary volatilization of the atomizing liquid, and also to achieve a thermal insulation effect. The silicon material can also avoid a hard contact between the liquid conducting body 131 and other parts, so as to avoid a damage of the liquid conducting body 131.

In one of the embodiments, the atomizer 100 further includes a housing 110. The housing 110 defines an air inlet 111 and an air outlet 112, the heating assembly 130 and the liquid reservoir 120 are received in the housing 110. The heating assembly 130 is located adjacent to the air inlet 111, and an airflow passage communicating the air inlet 111 and the air outlet 112 is provided between the housing 110 and the liquid reservoir 120. Airflow can enter from the air inlet 111, and the atomized gas obtained via an atomization of the heating element 132 flows along with the airflow, passes through the airflow passage and flows out from the air outlet 112 for smoking.
Moreover, in one of embodiments, the liquid reservoir 120 has a long tubular structure, and an outer wall of the liquid reservoir 120 is slightly less than an inner wall of the housing 110, such that the liquid reservoir 120 can be received in the housing 110. A gap between the outer wall of the liquid reservoir 120 and the inner wall of the housing 110 is relatively small, which is not conducive for the airflow and the atomized gas to be conducted out. A longitudinal groove 125 is defined on the outer wall of the liquid reservoir 120, such that an airflow passage is formed between the liquid reservoir 120 and the housing 110, so as to facilitate the airflow flowing along the longitudinal groove 125 and being conducted to the air outlet 112. Alternatively, the longitudinal groove 125 can be defined on the inner wall of the housing 110. Alternatively, the longitudinal grooves 125 can be simultaneously defined on the outer wall of the liquid reservoir 120 and the inner wall of the housing 110. Moreover, two longitudinal grooves 125 can be defined on the outer wall of the liquid reservoir 120, and the two longitudinal grooves 125 are oppositely arranged, so as to form two symmetrical airflow passages between the liquid reservoir 120 and the housing 110, such that a flux of gas and the atomized gas is increased, and the smoking taste is improved.
In one of the embodiments, a portion of the sealing element 133 is located between the liquid conducting body 131 and the liquid reservoir 120, so as to seal a gap between the liquid reservoir 120 and the liquid conducting body 131. The portion of the sealing element 133 abuts against the inner wall of the housing 110, such that more airflow entering through the air inlet 111 can reach the heating element 132 and is fully mixed with the atomized gas, so as to carry more atomized gas to the air outlet 112. At this time, the sealing element 133 defines a first notch 133f, the opening end 121 of the liquid reservoir 120 defines a second notch 126, and the first notch 133f and the second notch 126 communicate the air inlet 111 and the longitudinal groove 125. The airflow carrying the atomized gas enters the longitudinal groove 125 through the first notch 133f and the second notch 126, and is conducted out through the air outlet 112. Moreover, both of the number of the first notch 133f and the second notch 126 are two, such that two longitudinal grooves 125 can be in communication with the air inlet 111.
