Referring to fig. 1-4, in accordance with one embodiment of the present disclosure, an atomizing core assembly configured to form a sealing fit with a housing of an electronic cigarette is provided; the atomizing core assembly comprises a porous body 11 and a heating element assembly 12, wherein the porous body 11 is provided with a liquid absorbing surface and an atomizing surface, and the heating element assembly 12 is arranged on the atomizing surface of the porous body 11; the heating element assembly 12 comprises a first wire connection disc 121 and a second wire connection disc 122 which are arranged at intervals along the length direction of the porous body 11, the heating element assembly 12 further comprises a heating element 123, a first end of the heating element 123 is connected with the first wire connection disc 121, and a second end of the heating element 123 is connected with the second wire connection disc 122; the heating element 123 is provided with a curved bending part between the first end and the second end, and the curvature radius of the curved bending part is 0.1mm-2.5 mm.

Generally, since the area of the porous body in which the heat generating member is provided is very limited, in order to provide the heat generating member of the atomizing core assembly with high heat generation energy, the heat generating member needs to be curved, so that a large heat generating area can be obtained, and the more curved the curve, the larger the heat generating area can be obtained. However, if the curve of the heating element is too curved, the temperature difference between the two sides of the heating element is easily too large; and the more curved the curve of the heating member, the more thermal stress of the heating member, the higher the risk of the heating member breaking. Therefore, in the atomizing core subassembly that this application embodiment provided, the radius of curvature setting of the curved bending portion in 123 that will generate heat is in 0.1mm-2.5 mm's within range, can be favorable to the balanced area of generating heat and the temperature difference of a both sides that generate heat like this, under the circumstances of guaranteeing great area of generating heat, lets the difference in temperature of a both sides that generate heat less as far as possible, makes the thermal stress of the piece that generates heat less simultaneously, reduces the cracked risk of the piece that generates heat.

In one embodiment, the curved portion is further bent along the length direction of the porous body 11, and the curvature radius of the curved portion is 0.3mm-2.0 mm.

The larger the curvature radius of the curve bending part is, the smaller the curve bending degree is, namely the curve is more gentle, so that the temperature difference of two sides of the heating part is smaller, the thermal stress of the heating part is smaller when the heating part generates heat, and the risk of breakage of the heating part is lower; therefore, in this specific example, the minimum value of the curvature radius of the curved bent portion is set to 0.3mm to further ensure that the temperature difference between both sides of the heat generating member is small, and at the same time, the thermal stress of the heat generating member is made small, reducing the risk of breakage of the heat generating member; and the maximum value of the radius of curvature of the curved bent portion was set to 2.0mm to secure a sufficient heat generation area.

Referring to fig. 1, in one embodiment, the curved bent portion has bent peak portions 1231 and bent valley portions 1232 adjacently disposed, and a vertical distance between the bent peak portions 1231 and outer edges of the bent valley portions 1232 is 0.1mm to 3.0 mm.

The distance between the wave crest and the wave trough in the curve bending part of the heating part reflects the bending degree of the curve: the larger the distance between the peak and the trough is, the larger the bending degree of the curve is, and the smaller the distance between the peak and the trough is, the gentler the curve is. In this embodiment, the vertical distance between the outer edges of the bending wave crest portions 1231 and the bending wave trough portions 1232 which are adjacently arranged is set to be 0.1mm-3.0mm, so that the phenomenon that the line width error of the heating element after silk-screen printing is too large due to abrupt change of the curvature direction of the curve can be avoided under the condition that a large heating area is ensured, thereby avoiding the generation of local hot spots and local hot areas and greatly reducing the possibility of scorched smell.

More specifically, referring to fig. 1, the perpendicular distance between the outer edges of bending crest 1231 and bending trough 1232 refers to: referring to fig. 1, a vertical distance H between a first tangent and a second tangent is a distance between the outer edges of the bending crest 1231 and the bending trough 1232.

In one embodiment, the width of the heat generating member 123 in the width direction of the porous body 11 is 0.01mm to 1.5 mm.

The smaller the width of the heating member 123 is, the higher the heating temperature is, and the better the heating effect is; however, the smaller the width of the heat generating member, the greater the difficulty in manufacturing the heat generating member, and thus in this specific example, the width of the heat generating member 123 is set to be in the range of 0.01mm to 1.5 mm.

In one embodiment, the heat generating member 123 includes an effective heating section with a width smaller than a width threshold, the effective heating section is disposed in a middle section of the heat generating member 123, and a length of the effective heating section is 1mm-35 mm. Further, the width threshold of the effective heating section of the heat generating member 123 is 0.4 mm.

In this specific example, the length of the effective heating section is a length that the heating member can effectively generate heat; since the heating effect of the heating member is worse as the width of the heating member is larger, the part of the heating member 123 with the width smaller than the width threshold value is used as the effective heating section thereof, and the length of the effective heating section is ensured to be in the range of 1mm-35mm to ensure the heating effect of the heating member, and in some embodiments, the width threshold value may be 0.4 mm. Moreover, the effective heating section is arranged at the middle section of the heating member 123, so that a more uniform heating effect can be achieved.

In one embodiment, a part of the heat generating member 123 is embedded into the porous body 11 via the atomizing surface, and another part of the heat generating member 123 protrudes from the atomizing surface by 0.01mm to 1.5mm along the thickness direction of the porous body 11.

The smaller the thickness of the heating member 123 protruding the atomizing surface is, the higher the heating temperature of the heating member is, but the too high heating temperature may cause dry burning, thereby affecting the smoking taste of the electronic cigarette. The larger the thickness of the heating member 123 protruding out of the atomizing surface is, the lower the heating temperature of the heating member is, and the required heating requirement may not be met; in addition, when the total thickness of the heat generating member 123 is constant, the thickness of the protruding atomizing surface is smaller as the thickness of the protruding atomizing surface is larger, so that the bonding force between the heat generating member and the porous body is weak, and the heat generating member and the porous body are likely to be peeled off during the use of the electronic cigarette. Therefore, in the present embodiment, the thickness of the heat generating member 123 protruding from the atomizing surface is set to be in the range of 0.01mm to 1.5mm, so as to ensure a proper heat generating temperature and to ensure the bonding force of the heat generating member with the porous body.

As described above, referring to fig. 2, the longitudinal direction of the porous body 11 is the X direction in the drawing, the width direction of the porous body is the Y direction in the drawing, and the thickness direction of the porous body is the Z direction in the drawing.

In one embodiment, the heat generating members 123 are symmetrically disposed along a central axis of the porous body 11 in the width direction.

In one embodiment, a boss portion 13 is protruded from the surface of the porous body 11 away from the liquid absorption surface, the boss portion 13 protrudes from the outer surface of the porous body 11 to form the atomization surface, and the heat generating body assembly 12 is disposed on the atomization surface.

In this specific example, a boss portion 13 is provided on the porous body 11, the boss portion 13 having a first surface remote from the liquid-absorbing surface, and the heating element assembly 12 is provided on the first surface, so that both the first surface of the boss portion 13 and at least part of the side surface of the boss portion 13 can form the atomizing surface; the shape of the boss part 13 can be designed according to the shape and structure of the heating element assembly 12, so that the boss part 13 and the heating element assembly 12 are better adapted to achieve better heating effect and atomization effect.

In one embodiment, the outer edge of the heat generating member 123 is spaced from the outer edge of the boss portion 13 by a distance of 0.1mm to 8 mm.

Because the outside of the porous body 11 is sleeved with the sealing ring made of silica gel, and the porous body and the sealing ring are arranged in the shell of the electronic cigarette and form sealing abutment with the shell of the electronic cigarette; therefore, the smaller the distance between the outer edge of the heating member 123 and the outer edge of the boss portion 13, the closer the heating member 123 is to the seal ring and the casing of the electronic cigarette, which may cause the temperature of the seal ring and the casing of the electronic cigarette to increase too much, and may soften the seal ring and the casing of the electronic cigarette, thereby affecting the service life. However, the outer edge of the heat generating member 123 may not be as far from the outer edge of the boss portion 13 as possible. In this specific example, therefore, the distance of the outer edge of the heat generating member 123 from the outer edge of the boss portion 13 is set to 0.1mm to 8 mm.

Referring to fig. 2, in one embodiment, one side of the porous body 11 in the width direction is provided with a recessed portion 113, and the recessed portion 113 is formed by recessing one edge of the porous body 11 in the width direction toward the other edge.

Referring to fig. 1, in one embodiment, along the length direction of the porous body 11, the porous body 11 has a first edge 111 and a second edge 112, the first edge 111 is opened with a first ventilation groove 114, and the second edge 112 is opened with a second ventilation groove 115.

In this specific example, the porous body 11 is provided with the first ventilation through groove 114 and the second ventilation through groove 115, and when the porous body 11 is applied to an electronic cigarette, the first ventilation through groove 114 and the second ventilation through groove 115 are provided to facilitate the air pressure balance between the liquid storage cavity and the atomization cavity of the electronic cigarette, so as to avoid the occurrence of the situation that the tobacco tar is difficult to smoothly permeate from the liquid absorption surface to the atomization surface of the porous body, and prevent the dry burning from affecting the taste of the user during smoking.
