The utility model provides a heating component of an atomizing device, which comprises an oil guide member 11 and a heating member 12, and refers to fig. 1. The oil guide member 11 is provided with a through hole 111, and the heating member 12 is installed at the through hole 111. The oil guide member 11 is used for absorbing oil, the heating member 12 is used for atomizing the oil absorbed by the oil guide member 11 into aerosol, and the generated aerosol flows out from the through hole 111 for the user to suck. The oil guiding member 11 is provided with at least one liquid guiding groove 112 isolated from the through hole 111 corresponding to the heating member 12. The oil liquid can be buffered in the liquid guide groove 112 and then absorbed by the part of the oil guide part 11 close to the heating part 12 for the heating part 12 to atomize, so that the oil absorption area and the oil guide efficiency are increased, and the atomization efficiency is improved.

In some embodiments, as shown in fig. 1 to 4, the oil guiding member 11 may be a cylinder 351, a cube, a rectangular parallelepiped, or other shape that is adaptable according to the requirement. Preferably, the oil guide 11 is a rectangular parallelepiped structure, that is, the oil guide 11 has three edge lengths of length, width and height, the edge length of the oil guide 11 parallel to the axial direction of the through hole 111 is recorded as the height, and the longer edge length of the oil guide 11 perpendicular to the axial direction of the through hole 111 is recorded as the length, and the shorter edge length is recorded as the width. The rectangular parallelepiped oil guide 11 further has six side surfaces, two side surfaces parallel to each other at a distance of height are referred to as a first side 113, two side surfaces parallel to each other at a distance of length are referred to as a second side 114, and two side surfaces parallel to each other at a distance of width are referred to as a third side 115. The rectangular oil guide member 11 adopted in the embodiment can reduce the size of the atomizing device in the width direction of the oil guide member 11, so as to realize the flat arrangement of the equipment. In practical applications, the oil guide 11 is made of a porous material, such as porous ceramic. Preferably, the oil guide 11 has a porosity of 55% to 60%, for example, it may be 55%, 58% or 60%. Therefore, the efficiency of the oil guide piece 11 for absorbing oil can be ensured, and the toughness and the strength of the oil guide piece 11 can be ensured.

In some embodiments, as shown in fig. 2, the through hole 111 is located at the center of the oil guide 11. Thus, the oil liquid absorbed by the oil guide 11 from various directions can reach the through hole 111 with the shortest path and time, and be atomized by the heating member 12 installed at the through hole 111. Taking the oil guide 11 as a cuboid as an example, the through hole 111 passes through the center of the cuboid. Correspondingly, the heating element 12 forms an inner bore 122 which is coaxial with the through-bore 111. The diameter of the inner bore 122 is 1.5-2 mm. Preferably, the heating member 12 is at least partially embedded in the inner wall of the through hole 111 to increase the contact area with the oil guide member 11, thereby increasing the atomization area and improving the atomization efficiency. Thus, the aperture of the through hole 111 may be slightly larger than the diameter of the inner hole 122. The heating member 12 may be a heating wire that is spirally wound in a hollow cylindrical structure to form an inner hole 122 coaxial with the through hole 111. One end of the heating wire is provided with a lead wire 121, and the lead wire extends out of the oil guide member 11 from the through hole 111 to supply power for contact. Of course, the heating member 12 may also be a heating sheet, a heating net, or the like. The heating member 12 and the oil guide member 11 may be connected separately or integrally. In practical application, the heating element 12 and the oil guide element 11 are sintered to form an integral structure, so that the structure is stable and the processing efficiency is high.

In some embodiments, the opening direction of the liquid guiding groove 112 may be parallel to the axial direction of the through hole 111, or form an inclined angle with the axial direction of the through hole 111, or be perpendicular to the axial direction of the through hole 111. Preferably, the opening direction of the liquid guiding groove 112 is away from the through hole 111, and is perpendicular to the axial direction of the through hole 111. The liquid guiding groove 112 includes a bottom wall 1121 opposite to the opening and a side wall surrounding the bottom wall 1121. Thus, the bottom wall of the liquid guide groove 112 is opposite to the through hole 111, i.e. the projection area of the bottom wall in the axial direction of the through hole 111 is the largest. So that the oil buffered in the liquid guiding tank 112 is most easily absorbed by the heating element 12 from the bottom wall direction of the liquid guiding tank 112.

In some embodiments, the shape of the liquid guide groove 112 may be a rectangular groove, a square groove, a circular groove, or other regular or irregular shapes. The shape and size of the liquid guiding groove 112 can be adaptively changed according to the shape of the oil guiding member 11. For example, when the oil guiding member 11 is a cylinder 351, the oil guiding groove 112 is an arc-shaped groove, which may have a fan-shaped structure, and may have an annular structure along the axial direction of the cylinder 351. The bottom wall of the liquid guiding groove 112 may be a plane, a curved surface, a folded surface or an irregular surface, which may be a smooth surface or a rough surface, and which may be parallel to the axial direction of the through hole 111 or may form an inclined angle.

Preferably, a center line of a projected length of the bottom wall 1121 in the axial direction of the through hole 111 is located on the same plane as a center line of the heating member 12 in the axial direction, that is, the projected length is arranged in alignment with the axial height of the heating member 12. Meanwhile, the projection length is not less than the axial height of the heating element 12, so that the heating element 12 is ensured to be covered by the liquid guide groove 112 at each part in the axial direction, and therefore sufficient oil liquid supplement is ensured when each part atomizes oil liquid, not only is the atomization efficiency improved, but also the dry burning phenomenon of the oil guide element 11 can be effectively prevented.

Preferably, a center line of a projected width of the bottom wall 1121 in the radial direction of the through hole 111 is located on the same plane as the central axis of the heating member 12, that is, the projected width is aligned with the radial width of the heating member 12. Meanwhile, the projection width is not less than the diameter of the inner hole 122 of the heating element 12, so that all parts of the heating element 12 in the radial direction are all covered by the liquid guide groove 112, and sufficient oil liquid is supplemented to all parts when oil liquid is atomized, thereby not only improving the atomization efficiency, but also effectively preventing the dry burning phenomenon of the oil guide element 11.

In a preferred embodiment, as shown in fig. 1 and 2, the liquid guide groove 112 is a rectangular groove with an opening facing away from the through hole 111. Bottom wall 1121 of liquid guide groove 112 is aligned with through hole 111, and the plane of bottom wall is parallel to the axial direction of through hole 111. That is, the projected area of the bottom wall 1121 in the axial direction of the through hole 111 is equal to the area of the bottom wall 1121. The length of the bottom wall 1121 parallel to the axial direction of the through hole 111 is referred to as length, and the length of the bottom wall 1121 parallel to the radial direction of the through hole 111 is referred to as width. Preferably, the length of the bottom wall 1121 is not less than the length of the heating element 12 in the axial direction of the through hole 111, and the width of the bottom wall 1121 is not less than the width of the heating element 12 in the radial direction of the through hole 111. When the heating member 12 atomizes oil, the oil absorbed from the first side 113 and the second side 114 of the oil guide member 11 can be rapidly supplemented to the heating member 12 for atomization, and meanwhile, aerosol generated by atomization directly flows out through the through hole 111, so that the output efficiency of the aerosol is increased, and the concentration and the taste of the aerosol are ensured.

In practical applications, the liquid guiding groove 112 may be one, two or more. The liquid guide grooves 112 may be the same size or different sizes, and the sizes thereof may be adaptively adjusted according to the sizes of the heating members 12 in various directions. When there are two liquid guiding grooves 112, two second sides 114 opposite to the oil guiding member 11 are radially and symmetrically distributed in the two liquid guiding grooves 112, and the through hole 111 sequentially penetrates through the two first sides 113. Because the distance between the two second sides 114 is the largest, the oil can be buffered by the liquid guiding groove 112, the atomization efficiency of the oil absorbed from the two second sides 114 is accelerated, and the oil guiding members 11 on the two sides are prevented from being burnt. This allows the heating element 12 to be quickly replenished with oil from both the second side 114 and the third side 115. As shown in fig. 4, the number of the liquid guiding grooves 112 may be four, and the four liquid guiding grooves 112 are distributed on four sides of the oil guiding member 11 with the through hole 111 as the center, so as to ensure that the oil absorbed in all directions can be quickly supplemented to the heating member 12. It should be noted that, when there are a plurality of liquid guiding grooves 112, the plurality of liquid guiding grooves 112 may also be sequentially distributed at intervals along the height direction of the oil guiding member 11, and the distance between the liquid guiding grooves 112 at two ends is not less than the length of the heating member 12 in the axial direction.

In this way, the oil storage chamber 23 is sealed by the first seal ring 33 and the fixing seat body 311, that is, the mounting seat 3 serves as a chamber wall on one side of the sealed oil storage chamber 23 to carry oil. Preferably, the mounting seat 3 is opposite to the air outlet 211, so that the mounting seat 3 serves as a bottom wall of the sealed oil storage chamber 23 to carry the smoke injected into the oil storage chamber 23.

In some embodiments, as shown in fig. 6, the fixing base body 311 is provided with at least one oil hole (not shown) and a suitable sealing plug 35, and the sealing plug 35 is made of a dense soft rubber material and is inserted into the corresponding oil hole to seal the oil hole.

The oil stored in the oil storage chamber 23 can enter the liquid guiding groove 112 through the second clearance hole 3121 and the first clearance hole 321 to increase the oil suction area and reduce the oil suction path. On the other hand, because the second clearance hole 3121 is disposed in the fixed seat 31, and the fixed seat 31 forms the bottom wall of the sealed oil storage cavity 23, the oil is buffered in the liquid guide groove 112 under the action of gravity, which is not only beneficial to accelerating the absorption of the oil guide member 11 to the oil, but also beneficial to the full utilization of the oil, and reduces the waste of the oil.

Preferably, in order to facilitate the oil to enter the second clearance hole 3121 more smoothly from the oil storage chamber 23, a guiding notch 3122 is provided on the hole wall of the second clearance hole 3121 near the second end 302 of the mounting seat 3. That is, the guide notch 3122 is disposed on one side of the second avoiding hole 3121 close to the second opening 313, the guide notch 3122 extends in a direction away from the center of the accommodating groove and has an inclined guide surface to increase an oil inlet area of the second avoiding hole 3121, so that the oil is guided to smoothly flow into the second avoiding hole 3121 and then enter the liquid guide groove 112.

Further, two support columns 2216 are respectively provided with a wire through groove 2213 communicated with the mounting holes 2212. The two leads 121 led out from the heating member 12 are bent into the supporting columns 2216, and sequentially pass through the corresponding supporting columns 2216 and the corresponding wire passing grooves 2213 to enter the mounting holes 2212, so that when the conductive contact piece 222 is pressed into the mounting hole 2212, the corresponding lead 121 is pressed into the mounting hole 2212, and stable electrical contact is ensured. The wire passing and mounting mode can form stable electric contact without additional welding wires, reduces the welding wire procedures and improves the assembly efficiency. Meanwhile, the wire passing and air passing of the embodiment share one channel, so that the internal space is saved, and the structure is simplified.

In some embodiments, the base 22 further includes a bottom cover 224 covering the base body 221, and the bottom cover 224 is provided with a fifth space-avoiding hole 2241 corresponding to the mounting hole 2212 and a sixth space-avoiding hole 2242 communicated with the air inlet hole 2211. Preferably, a vent groove 2214 is arranged on one side of the base body 221 away from the cover 21, and an air inlet end of the air inlet 2211 is located in the vent groove 2214. Preferably, the vent slots 2214 are cross-shaped. The two air inlet holes 2211 are respectively located at two opposite ends of the vent groove 2214, the number of the sixth avoiding holes 2242 is two, and the two sixth avoiding holes 2242 are respectively opposite to the other two opposite ends of the vent groove 2214. Thus, the air inlet holes 2211 are covered by the cover body 21, so that external dust or liquid is prevented from entering the air inlet holes 2211, and the air inlet holes 2211 are protected. Meanwhile, the two sixth avoiding holes 2242 are communicated with the air inlet holes 2211 through the vent grooves 2214, so that an air inlet passage of air flow is ensured. In practical application, the sixth avoiding holes 2242 which are symmetrically arranged can be matched with the ventilating column on the power supply device, so that the atomization device is convenient to assemble.
