The height dimension of the porous substrate 12 is 3.0 mm or more and 5 mm or less, and the height dimension may be 3.0 mm, 3.3 mm, 3.5 mm, 4.5 mm, or 5 mm.

The above dimensions of the porous matrix 12 are suitable for its application in the atomizer 100, facilitating its compact design while also meeting drainage requirements.

On the basis, the present application further optimizes the dimensions of the atomizing assembly 10 to make the atomizing efficiency of the atomizing assembly 10 more efficient and to avoid dry-out and scorched smell in the areas of the atomizing surface 122 due to insufficient liquid supply.

Specifically, referring to fig. 4 and 7 in combination, the atomizing surface 122 has a first length side 1221 and a second length side 1222 spaced apart in the width direction, the heat generating line 143 is disposed in a spaced area between the first length side 1221 and the second length side 1222, an outer liquid supply area is formed between the heat generating line 143 and the first length side 1221 and the second length side 1222, respectively, and the heat generating line 143 is spaced apart from the first length side 1221 and the second length side 1222 by the same distance.

In this embodiment, in the width direction of the porous substrate 12, the ratio between the spacing distance C between the outermost edges of the two farthest straight segments 144 away from each other and the width dimension a of the atomizing surface 122 is greater than or equal to 0.45 and less than or equal to 0.65, so that the heat generating line 143 can simultaneously consider the middle liquid supply region and the outer liquid supply region along the width direction on the atomizing surface 122, the temperature unevenness on the atomizing surface 122 is improved, the atomizing effect is improved, and the energy utilization rate and the atomizing efficiency of the heat generating line 143 are favorably improved.

Wherein the first length edge 1221 and the second length edge 1222 are spaced apart by a distance equal to the width dimension a of the atomizing surface 122. In this embodiment, the first straight line segment 1441 is disposed adjacent to the first length side 1221, the third straight line segment 1443 is disposed adjacent to the second length side 1222, and the spacing distance C between the outermost edges of the first straight line segment 1441 and the third straight line segment 1443 is the maximum dimension of the heat generating line 143 in the width direction.

Through a great deal of research and demonstration, regarding the possible adopted size of the atomizing surface 122 of the existing porous substrate 12, the position of the heating wire 143 on the atomizing surface 122 meets the ratio range, the middle liquid supply area covered by the heating wire 143 and the formed outer liquid supply area can be considered at the same time, the outer liquid supply area can ensure sufficient liquid supply, dryness and scorched smell caused by insufficient liquid supply can be avoided, and the overall atomizing efficiency and the energy utilization rate of the heating wire 143 on the atomizing surface 122 are effectively improved.

If the ratio of the separation distance C to the width dimension A is less than 0.45, the outer liquid supply region is formed too large, and the stronger the liquid supply capacity of the outer liquid supply region, the more liquid supply may result, such that the liquid substrate atomization efficiency of the outer liquid supply region by the heat generating line 143 is not high. If the ratio of the spacing distance C to the width dimension a is greater than 0.65, the formed outside liquid supply area is too small, which may result in insufficient liquid supply in the outside liquid supply area, and further the heating wire 143 may easily generate scorched smell during atomization, so that the energy utilization rate is not high, which may cause a great amount of energy waste and may impair the service life of the atomization assembly 10.

Further, in the width direction of the porous substrate 12, the ratio of the spacing distance E of the adjacent straight line segments 144 along the width direction of the porous substrate 12 to the line width H of the heat generating line 143 is greater than or equal to 1.3 and less than or equal to 2.5, so as to further improve the atomization efficiency of the liquid supply area between the adjacent straight line segments 144, and enable the heat generating line 143 to reasonably cover and radiate more middle liquid supply areas in the atomization surface 122, that is, the overall atomization efficiency of the heat generating line 143 to the middle liquid supply area is optimized, the temperature unevenness on the atomization surface 122 is further improved, the atomization effect is improved, and the energy utilization rate and the atomization efficiency of the heat generating line 143 are favorably improved.

The line width H of the heat generating line 143 is in a range of 0.3 mm to 0.45 mm, and may be 0.3 mm, 0.35 mm, 0.38 mm, 0.40 mm, 0.42 mm, or 0.45 mm, and the spacing distance E between adjacent straight line segments 144 in the width direction of the porous base 12 may be 0.6 mm, 0.7 mm, or 1.0 mm, or the like.

Accordingly, the number of the straight line segments 144 on the atomizing surface 122 can be reasonably adjusted by combining with the width dimension A of the porous substrate 12, so that the atomizing surface 122 has uniform temperature in the range of the middle liquid supply area in the width direction, and the atomizing efficiency is high.

Further, the ratio of the distance D between the outermost edge of the straight line segment 144 and the edge of the adjacent atomizing surface 122 to the line width H of the heat generating line 143 is greater than or equal to 2.5 and less than or equal to 3.0, the distance D is the interval between the first straight line segment 1441 and the first length edge 1221, or the distance D is the distance between the third straight line segment 1443 and the second length edge 1222, so as to further improve the atomizing efficiency of the heat generating line 143 on the outer liquid supply region, balance the liquid supply amount of the outer liquid supply region and the heating efficiency of the heat generating line 143 on the outer liquid supply region, further improve the temperature unevenness of the outer liquid supply region on the atomizing surface 122, and improve the atomizing effect.

The spacing D may be 0.9 mm, 1.0 mm, 1.15 mm, or 1.2 mm.

It should be noted that the liquid supply efficiency of the liquid supply region in the middle of the atomizing surface 122 is generally higher than that of the liquid supply region at the outer side, that is, the liquid supply amount per unit time of the liquid supply region in the middle is higher than that of the liquid supply region at the outer side under the same area, so that the ratio of the spacing distance E to the line width H is smaller than that of the spacing distance D to the line width H.

Further, in the length direction of the porous substrate 12, the ratio of the distance F between the arc tops of the first arc segment 1451 and the second arc segment 1452 to the distance G between the first electric connection part 141 and the second electric connection part 142 is greater than or equal to 0.5 and less than or equal to 0.7, so that the heating wire 143 can simultaneously take into account the middle liquid supply area and the outer liquid supply area along the length direction on the atomizing surface 122, the temperature unevenness on the atomizing surface 122 is improved, the atomizing effect is improved, and the energy utilization rate and the atomizing efficiency of the heating wire 143 are improved.

An area between the arc top of the first arc segment 1451 and the first electric connection part 141 and an area between the arc top of the second arc segment 1452 and the second electric connection part 142 are outer liquid supply areas of the atomizing surface 122 in the length direction, and an area between the arc top of the first arc segment 1451 and the arc top of the second arc segment 1452 is a middle liquid supply area of the atomizing surface 122 in the length direction.

The first arc 1451 and the second arc 1452 outside the range will result in insufficient liquid supply area of the outer liquid supply region and dry burning, or will result in sufficient area of the outer oil supply region and low atomization efficiency, which will result in low energy utilization rate.

Further, the ratio of the area occupied by the heat generation line 143 in the atomizing surface 122 to the total area of the atomizing surface 122 is 0.1 or more and 0.3 or less. Controlling the ratio to 0.1 to 0.3 by adjusting the shape of the heating wire 143 and the area of the atomizing surface 122 effectively reduces heat transfer to the porous base 12 and the air, improves high temperature concentration in the middle of the atomizing surface 122, effectively improves energy utilization on the heating wire 143, and improves atomization.

Further, the ratio of the length L of the atomizing surface 122 to the length B of the porous substrate 12 is greater than or equal to 0.75 and less than or equal to 1.0, so as to optimize the range occupied by the atomizing surface 122, improve the liquid guiding efficiency of the porous substrate 12, and avoid the insufficient liquid supply to the heat generating line 143 due to unsmooth liquid discharge of the porous substrate 12 caused by a small atomizing surface.

The length dimension L of the atomizing surface 122 is smaller than the length dimension B of the porous base body 12, i.e., the porous base body 12 is provided with a stopper step.

Further, the ratio of the distance G between the first power connection part 141 and the second power connection part 142 to the length L of the atomizing surface 122 is greater than or equal to 0.55 and less than or equal to 0.8, so as to reasonably plan the area irradiated by the heating wire 143, improve the atomizing effect, avoid the phenomena of dry burning and the like in the area between the first power connection part 141 and the second power connection part 142, and improve the energy utilization rate.
