Technical Field
The invention relates to the technical field of electronic heating, in particular to a heating body, a heating assembly and an electronic atomizer.
Background
Electronic atomizers release aerosols by heating the atomizing medium or atomizing medium carrier (e.g., the cartridge) with a heat-generating body.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 and 2, according to an embodiment of the present invention, a heating assembly 10 is provided, where the heating assembly 10 includes a first casing 110 and a heating element 120.
Specifically, the first housing 110 is used to accommodate the object 100 to be heated. The object 100 to be heated may be selected according to the use of the heating assembly 10. In the present embodiment, the heating assembly 10 is used as a component of a cryogenic electronic atomizer for heating an aerosol bomb. Therefore, in the present embodiment, the object 100 to be heated is a cartomizer. It is understood that in other embodiments, the object 100 to be heated may be adjusted according to actual conditions.
Specifically, the first housing 110 has a heating groove that accommodates the object 100 to be heated. In the illustrated embodiment, the object 100 to be heated is partially accommodated in the heating tank. Of course, in other embodiments, the size of the heating slot may be adjusted according to actual requirements. For example, in some embodiments, the heating groove is provided as a space capable of completely accommodating the object 100 to be heated.
Specifically, the heating element 120 is used to heat the object 100 to be heated, and the heating element 120 is housed in a heating tank. In the illustrated embodiment, the heating element 120 is partially housed in a heating tank. Of course, in other embodiments, all of the heating elements 120 may be accommodated in the heating tank.
Referring to fig. 3 to 6, the heating element 120 includes a heating base 121, the heating base 121 is a hollow structure, one end of the heating base 121 is open, and the other end is closed, a vent hole 122 is disposed on the heating base 121, the vent hole 122 is close to the closed end of the heating base 121, and the vent hole 122 communicates the hollow portion of the heating base 121 with an external space to form an airflow channel.
Specifically, the heat generating base 121 includes a top portion 121a and a body 121b, the body 121b is a hollow structure with two open ends, the top portion 121a is hermetically connected to one end of the body 121b and shields the opening of the end of the body 121b, a vent hole 122 is disposed on the body 121b, and the vent hole 122 is close to the top portion 121a and communicates with the external space and the hollow portion of the body 121b to form an airflow channel.
The research of the application discovers that when a heating body of the traditional low-temperature electronic atomizer is matched with a first shell to heat an atomizing bullet, the outside air only enters a heating groove from the bottom of the first shell (namely the outside air is close to the end face of the first shell from the atomizing bullet) or the side wall of the first shell and is sucked away, however, after the atomizing bullet is inserted on the heating body, due to the fact that the density of the part close to the heating body is improved and is close to the heating body, excessive baking is easy to occur, and scorched substances generated by the excessive baking are easily sucked along with air flow; and the atomizing bomb is heated under the anoxic condition to generate stronger fragrance. Therefore, the above-mentioned heating element 120 (see fig. 5 or fig. 6, and the dotted arrows in fig. 5 and fig. 6 indicate the direction of the gas flow) changes the flow path of the air flow by providing the vent hole 122 in the area of the body 121b near the top 121a, so that the outside air flows in from the hollow part of the body 121b and flows into the heating tank through the vent hole 122 near the top 121a, thereby reducing the amount of the scorched substances generated by the high-temperature overbaking near the high-temperature region, which are carried out by the air flow, and simultaneously providing the anoxic environment to the mist bomb near the bottom of the first casing 110, so that the mist bomb can generate a strong fragrance, thereby reducing the scorched smell and increasing the fragrance, and improving the taste of the mist bomb after being heated.
Alternatively, the heat generating body 120 is hermetically connected to the first case 110. At this time, the entire air flow flows into the heating bath through the air flow passage of the heating element 120. Of course, the heat generating body 120 and the first case 110 may be connected in a non-sealed manner or a through hole may be provided in the bottom of the first case 110. At this time, a part of the air current enters the heating bath from the connection of the heating body 120 and the first case 110 or from the bottom of the first case 110.
Alternatively, the heating body 120 base is a metal heating base or a ceramic heating base. Specifically, the body 121b is a metal body or a ceramic heat-generating body. The top 121a is a metal top or a ceramic heating top. Of course, the materials of the heat generating base 121, the top 121a and the body 121b are not particularly limited as long as they can heat the object 100 to be heated by heat. In some embodiments, the heat generating base 121 includes a base and heat generating components stacked on the base. The heat generating base 121 generates heat by the heat generating components on the heat generating base 121. In other embodiments, the heat generating substrate 121 is directly made of a heat generating material, and in this case, the substrate is omitted. Alternatively, the heat generating base 121 is a hollow needle or a hollow cone. In the illustrated embodiment, the heat generating base 121 has a hollow needle shape. In the present embodiment, the body 121b is integrally formed with the top 121 a. Of course, in other embodiments, the body 121b and the top 121a may be spliced together.
Alternatively, the cross-sectional area of the top portion 121a gradually decreases from a direction close to the body 121b to a direction away from the body 121 b. Insertion of the object 100 to be heated (e.g., a cartomizer) into the heat-generating body 120 can be facilitated by disposing the top portion 121a in this manner. In the illustrated embodiment, the top portion 121a is tapered.
Optionally, the body 121b has a hollow cylindrical structure with two open ends. Of course, in other embodiments, the structure of the body 121b is not limited to the above, and may be other hollow structures. The body 121b has an inner surface 121c and an outer surface 121 d. The inner surface 121c of the body encloses a hollow portion of the body 121b, and the outer surface 121d of the body is closer to the inner surface of the first housing 110.
Specifically, the vent hole 122 being close to the top 121a means that the vent hole 122 is provided in a section of the body 121b close to the top 121a, which is closer to the top 121a than to the bottom end of the body 121b close to the first housing 110. Optionally, the vent 122 is disposed in a 0mm to 6mm area of the body 121b near the top 121 a. Further, the vent hole 122 is disposed in an area of 0mm to 4mm of the body 121b near the top 121 a. The research shows that the vent holes 122 are arranged in the area of 0 mm-4 mm of the body 121b close to the top 121a, so that the scorched flavor is less, the fragrance is stronger, and the overall taste is better.
Optionally, a plurality of vent holes 122 are spaced on the body 121b, each vent hole 122 is communicated with the hollow part and the external space of the body 121b to form a gas flow channel for gas to flow through, and the plurality of vent holes 122 spaced from each other are disposed in an area of 0mm to 6mm of the body 121b close to the top 121 a. That is, the plurality of vent holes 122 spaced apart from each other are provided in the vent hole installation area of the body 121b, and the maximum distance from the bottom side of the vent hole installation area close to the first casing 110 to the connection between the body 121b and the top 121a is 0mm to 6 mm.
Specifically, in some embodiments, the plurality of spaced apart vent holes 122 are disposed on the body 121b near the top 121a and distributed annularly around a central axis of the body 121b, wherein a distance between the vent hole 122 closest to the top 121a and a junction of the top 121a and the body 121b is greater than 0mm and less than 3mm (e.g., 0.5mm, 1mm, 2mm, or 2.5mm), and a distance between the vent hole 122 farthest from the top 121a and the junction of the top 121a and the body 121b is greater than 3mm and not greater than 6mm (e.g., 3.5mm, 4mm, 5mm, or 6 mm). In a specific example, a plurality of spaced vent holes 122 are disposed on the body 121b near the top 121a and distributed in a ring shape around the central axis of the body 121b, and the vent holes 122 are disposed in the middle of the body 121b near the top 121 a. For example, the distance between the vent hole 122 closest to the top 121a and the junction between the top 121a and the body 121b is 3mm, and the distance between the vent hole 122 farthest from the top 121a and the junction between the top 121a and the body 121b is 4 mm. That is, the vent hole 122 is provided in an area having a distance of 3mm to 4mm from the top 121 a. It is understood that in other embodiments, the distance between the vent hole 122 closest to the top 121a and the connection between the top 121a and the body 121b, and the distance between the vent hole 122 farthest from the top 121a and the connection between the top 121a and the body 121b are not limited to the above dimensions, and can be adjusted according to actual conditions.
Of course, in another specific example, the plurality of vent holes 122 may be arranged in a ring-shaped circle on the body 121b around the central axis of the body 121b, that is, the plurality of vent holes 122 may be arranged at a distance of 4mm from the top 121 a. It is understood that in other embodiments, the distance between the vent hole 122 and the top 121a is not limited to 4mm, but may be other sizes ranging from 0mm to 6 mm.
Further, the plurality of vent holes 122 are disposed in an area of 0mm to 4mm of the body 121b near the top 121 a. It should be noted that, herein, the distance between the vent hole 122 nearest to the top 121a and the junction between the top 121a and the body 121b refers to the minimum distance from the hole wall of the vent hole 122 nearest to the top 121a to the junction between the top 121a and the body 121 b; the distance between the vent hole 122 farthest from the top 121a and the junction of the top 121a and the body 121b refers to the maximum distance from the hole wall of the vent hole 122 farthest from the top 121a to the junction of the top 121a and the body 121 b.
In the illustrated embodiment, the plurality of vent holes 122 are arranged in an array with approximately equal spacing between adjacent vent holes 122. Of course, in other embodiments, the air holes 122 are not limited to be arranged in an array with substantially equal intervals, and may be adjusted according to actual requirements. It is understood that in other embodiments, the plurality of vent holes 122 are not limited to be distributed on the body 121b in a ring shape around the central axis of the body 121b, and may be adjusted according to actual requirements. For example, the plurality of vent holes 122 are arranged at intervals on one side of the body 121b, and the region opposite to the one side is free of the vent holes 122.
It is to be understood that the number of the vent holes 122 is not limited to the above-mentioned plurality, and may be only one as long as the external space and the hollow portion of the body 121b can be communicated. When the vent hole is one, the distance between the joint of the body 121b and the top 121a and the vent hole 122 is 0 mm-6 mm. Further, the distance between the joint of the body 121b and the top 121a and the vent hole 122 is 0mm to 4 mm. The research shows that when the distance between the joint of the body 121b and the top 121a and the vent 122 is set to be 0-4 mm, the scorched flavor is less, the fragrance is stronger, and the overall taste is better.
In some embodiments, each vent hole 122 is a tapered hole, and the section of each vent hole 122 near the inner surface 121c of the body has a larger aperture than the section thereof near the outer surface 121d of the body. By setting the aperture of the section of the vent hole 122 close to the inner surface 121c of the body to be larger than the aperture of the section of the vent hole 122 close to the outer surface 121d of the body, the flow passage of the air flow flowing out from the hollow part of the body 121b through the vent hole 122 is narrowed, so that the air flow flowing out from the body 121b has a larger impact force, and the outer surface 121d of the body is less prone to adhering or adhering dirt, and dirt residue is reduced. In a specific example, each of the vent holes 122 is a tapered hole, and the diameter of each of the vent holes 122 is gradually reduced from the central space of the heat generating base 121 to the outer space. In other embodiments, each vent hole 122 is a through hole. Of course, the vent hole 122 is not limited to the through hole and the tapered hole, and may be a through hole having any other shape.
Optionally, the area of the cross section of the hollow portion of the body 121b occupies 50% to 90% of the area of the cross section of the body 121 b. The arrangement can make the air flow more smoothly in the heat generating base body 121. It should be noted that the area of the cross-sectional area of the body 121b is the area of a figure defined by a projection of the outer surface 121d of the body on a plane perpendicular to the central axis of the body 121b, and includes the area of the cross-section of the hollow portion of the body 121 b. Taking the body 121b as a hollow cylinder as an example, after the body 121b is transversely cut along a central axis perpendicular to the body 121b, a ring shape is formed, the area of the cross section of the hollow portion of the body 121b is the area of the inner circle of the ring shape, and the area of the cross section of the body 121b is the area of the outer circle of the ring shape. In an alternative specific example, the area of the cross-section of the hollow portion of the body 121b accounts for 60%, 70%, 75%, 80%, 85%, or 90% of the area of the cross-section of the body 121 b.
Specifically, each vent hole 122 has an air inlet at the inner surface 121c of the body and an air outlet communicating with the air inlet and at the outer surface 121d of the body. In the illustrated embodiment, the vent hole 122 is a through hole, the center lines of the outlet air and the inlet air are collinear, the extending direction of the vent hole 122 is perpendicular to the extending direction of the body 121b, and the center line of the outlet air is perpendicular to the center line of the body 121 b. In other embodiments, the vent 122 is inclined away from the top 121a of the body 121b from the air inlet to the air outlet. At this time, the airflow flows towards the end of the body 121b away from the top 121a, so that more airflow flows through the cartomizer, and the utilization rate of the cartomizer can be improved. It will be appreciated that in some embodiments, the air outlets of each vent hole 122 may also be disposed toward the tip portion. In the present embodiment, the air outlets of the air vents 122 are all oriented in the same direction. It is understood that in other embodiments, the air outlets of the air vents 122 may not be oriented exactly the same. For example, the air outlets of a part of the vent holes 122 face a direction perpendicular to the extending direction of the body 121b, and the air outlets of a part of the vent holes 122 face one end of the body 121b far away from the top 121 a.
Optionally, the aperture of the vent 122 is 0.1mm to 0.3 mm. In one specific example, the vent 122 has a pore size of 0.1mm, 0.2mm, or 0.3 mm.
Alternatively, the area of the outer surface of the heat generating base 121 is 180mm2～360mm2(ii) a The total area of the openings of the respective vent holes 122 on the outer surface of the body 121b is not less than 0.6mm2(ii) a The opening area of each vent hole 122 is 0.07-0.4 mm2. Further, the area of the outer surface of the heat generating base 121 is 200mm2～260mm2(ii) a The total area of the openings of the respective vent holes 122 on the outer surface of the body 121b is 0.6mm2～2.4mm2。
In some embodiments, the heat generating body 120 further includes a protective layer 123 disposed on the outer surface of the heat generating base 121, and the protective layer 123 is also provided with air outlets 124 correspondingly communicating with the air vents 122. The air outlet 124 communicates with the vent hole 122 so that the air outlet 124, the vent hole 122 and the hollow portion of the body 121b form an air flow passage. The protective layer 123 is used to protect the heating substrate 121, reduce the influence of dirt on the utilization efficiency of heat generated by the heating element 120, and also reduce the influence of dirt on the taste of the aerosol bomb. In some embodiments, the orientation of the air exit aperture 124 is the same as the orientation of the air vent aperture 122. Of course, in other embodiments, the orientation of the air outlet 124 may be different from the orientation of the air vent 122.
Optionally, the protective layer 123 is a glass protective layer 123 or an infrared ceramic protective layer 123. The glass protective layer 123 makes dirt less likely to adhere to the surface thereof due to the anti-adhesion of glass. The infrared ceramic protective layer 123 makes dirt less likely to adhere by the infrared ceramic absorbing the heat of the heating body 120. In an alternative embodiment, the protective layer 123 is a glass glaze layer.
