Description

Technical Field

[0001] The present invention relates to the technical field of electronic heating, and in particular to a heating element, a heating component and an electronic atomizer. Background Art

[0002] Electronic atomizers primarily release aerosols by heating the atomizing medium or a carrier (e.g., atomizer cartridge) through a heating element. Low-temperature electronic atomizers primarily produce aerosols by baking the atomizing cartridge at temperatures between 200°C and 400°C, but without the release of harmful substances that would be produced by high-temperature decomposition. This makes them popular with users.

[0003] Currently, low-temperature electronic atomizers use two heating methods: central heating (heating the atomizer cartridge by inserting a heating element directly into the cartridge) and peripheral heating (heating the atomizer cartridge by placing it in a tubular heating element). Central heating has high thermal efficiency and does not require insulation, making it the primary heating method. However, in actual use, it has been found that low-temperature electronic atomizers using central heating are prone to a burnt smell and lack aroma, resulting in a poor taste. Summary of the Invention

[0004] Based on this, it is necessary to provide a heating element that can make the low-temperature electronic atomizer less likely to have a burnt smell and make the aroma of the heated atomizer cartridge more intense.

[0005] A heating element includes a heating base, which is a hollow structure with one end open and the other end closed. A vent is provided on the heating base, and the vent is close to the closed end of the heating base. The vent connects the hollow part of the heating base with the external space to form an air flow channel.

[0006] The heating element is provided with an air vent near the closed end of the heating base, and the air vent is connected to the hollow part of the heating base and the external space to form an air flow channel for gas circulation. The air flow path of the heating element is different from that of traditional heating elements when in use. The air flow does not directly pass through the lower area of the atomizer, which makes this area heated in an oxygen-deficient environment and produces a richer aroma. The air vent is also located outside the high-temperature zone, which greatly reduces the burnt smell of the atomizer produced by over-baking in the high-temperature zone. Therefore, the heating element can improve the problem of insufficient aroma and easy burnt smell when the atomizer is heated by low-temperature electronic atomizers.

[0007] In one embodiment, the heating base includes a top and a body, the body is a hollow structure with openings at both ends, the top is sealedly connected to one end of the body and covers the opening at that end of the body, and the vent is arranged on the body and close to the top.

[0008] In one embodiment, there are multiple ventilation holes, and the multiple ventilation holes are arranged at intervals within a region of 0 mm to 6 mm near the top of the main body.

[0009] In one embodiment, the plurality of ventilation holes are arranged in a region of 0 mm to 4 mm near the top of the body.

[0010] In one embodiment, the number of the vent hole is one, and the distance between the connection between the body and the top and the vent hole is 0 mm to 6 mm.

[0011] In one embodiment, the distance between the connection between the body and the top and the vent hole is 0 mm to 4 mm.

[0012] In one embodiment, the vent hole is a cylindrical straight through hole;

[0013] Alternatively, the vent hole is a tapered hole, and the diameter of the vent hole gradually decreases from the hollow part of the body to the external space.

[0014] In one embodiment, the vent has an air inlet located on the inner surface of the body and an air outlet located on the outer surface of the body, and the vent is obliquely away from the top in a direction from the air inlet toward the air outlet.

[0015] In one embodiment, the diameter of the vent hole is 0.1 mm to 0.3 mm.

[0016] In one embodiment, the total area of the openings of the vent holes on the outer surface of the body is 0.6 mm 2 ~2.4mm 2 and / or,

[0017] The opening area of each vent hole is 0.07mm 2 ~0.4mm 2 .

[0018] In one embodiment, the cross-sectional area of the hollow portion of the body accounts for 50% to 90% of the cross-sectional area of the body.

[0019] In one embodiment, the heating substrate is in the shape of a hollow needle, a hollow sheet or a hollow cone;

[0020] And / or, the heating element substrate is a metal heating substrate or a ceramic heating substrate.

[0021] In one embodiment, the heating element further includes a protective layer located on the outer surface of the heating base, and the protective layer is also provided with air outlet holes corresponding to and connected to the air vents.

[0022] In one embodiment, the protective layer is a glass protective layer or an infrared ceramic protective layer.

The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See also Figure 1 and Figure 2 In one embodiment of the present invention, a heating assembly 10 is provided. The heating assembly 10 includes a first shell 110 and a heating element 120 .

[0045] Specifically, the first housing 110 is used to accommodate the object to be heated 100. The object to be heated 100 can be selected based on the purpose of the heating assembly 10. In this embodiment, the heating assembly 10 is a component of a low-temperature electronic atomizer, used to heat an atomizing cartridge. Therefore, in this embodiment, the object to be heated 100 is an atomizing cartridge. It is understood that in other embodiments, the object to be heated 100 can be adjusted based on actual conditions.

[0046] Specifically, the first housing 110 includes a heating tank for accommodating the object 100 to be heated. In the illustrated embodiment, the object 100 to be heated is partially accommodated within the heating tank. Of course, in other embodiments, the size of the heating tank can be adjusted based on actual needs. For example, in some embodiments, the heating tank is configured to completely accommodate the object 100 to be heated.

[0047] Specifically, the heating element 120 is used to heat the object to be heated 100, and the heating element 120 is accommodated in the heating tank. In the embodiment shown in the figure, the heating element 120 is partially accommodated in the heating tank. Of course, in other embodiments, the heating element 120 can also be fully accommodated in the heating tank.

[0048] See also Figures 3 to 6 The heating element 120 includes a heating base 121. The heating base 121 is a hollow structure with one end open and the other end closed. A vent 122 is provided on the heating base 121. The vent 122 is close to the closed end of the heating base 121. The vent 122 connects the hollow part of the heating base 121 with the external space to form an air flow channel.

[0049] Specifically, the heating base 121 includes a top 121a and a main body 121b. The main body 121b is a hollow structure with openings at both ends. The top 121a is sealed and connected to one end of the main body 121b and covers the opening at that end of the main body 121b. A vent 122 is provided on the main body 121b. The vent 122 is close to the top 121a and connects the external space and the hollow part of the main body 121b to form an air flow channel.

[0050] The research of this application found that when the heating element of the traditional low-temperature electronic atomizer cooperates with the first shell to heat the atomizer cartridge, the outside air only enters the heating tank from the bottom of the first shell (that is, the outside air enters the heating tank from the end face of the atomizer cartridge close to the first shell) or the side wall of the first shell and is then sucked away. However, after the atomizer cartridge is inserted into the heating element, it is easy to be over-baked because the density of the part close to the heating element is increased and it is closer to the heating element. The burnt smell generated by the over-baking is easily inhaled with the air flow; and the aroma generated by the atomizer cartridge when heated under oxygen-deficient conditions is more intense. Therefore, the above-mentioned heating element 120 (please refer to Figure 5 or Figure 6 , Figure 5 and Figure 6 (The dotted arrow in the figure indicates the direction of gas flow) By providing an air vent 122 in the area of the main body 121b near the top 121a, external air flows in from the hollow part of the main body 121b and flows into the heating tank through the air vent 122 near the top 121a, thereby changing the flow path of the airflow and reducing the amount of burnt odor substances produced by excessive baking near the high-temperature area and carried out by the airflow. At the same time, an oxygen-deficient environment is provided to the atomizer bomb near the bottom of the first shell 110, so that this part of the atomizer bomb can produce a rich aroma, thereby reducing the burnt smell and increasing the aroma, and improving the taste of the atomizer bomb after heating.

[0051] Optionally, the heating element 120 is sealedly connected to the first housing 110. In this case, the airflow flows entirely through the airflow channel of the heating element 120 into the heating tank. Of course, the heating element 120 and the first housing 110 may also be non-sealedly connected, or a through hole may be provided at the bottom of the first housing 110. In this case, part of the airflow enters the heating tank from the connection between the heating element 120 and the first housing 110 or from the bottom of the first housing 110.

[0052] Optionally, the base of the heating element 120 is a metal heating base or a ceramic heating base. Specifically, the main body 121b is a metal main body or a ceramic heating main body. The top 121a is a metal top or a ceramic heating top. Of course, there is no special restriction on the materials of the heating base 121, the top 121a and the main body 121b, as long as they can generate heat to heat the object 100 to be heated. In some embodiments, the heating base 121 includes a base and a heating component stacked on the base. The heating base 121 generates heat through the heating components on the heating base 121. In other embodiments, the heating base 121 is directly made of heating material, in which case the base is omitted. Optionally, the heating base 121 is hollow needle-shaped or hollow cone-shaped. In the illustrated embodiment, the heating base 121 is hollow needle-shaped. In this embodiment, the main body 121b and the top 121a are integrally formed. Of course, in other embodiments, the main body 121b and the top 121a can also be spliced together.

[0053] Optionally, the cross-sectional area of the top portion 121a gradually decreases from the direction close to the main body 121b to the direction away from the main body 121b. By configuring the top portion 121a in this manner, it is easier to insert the object 100 to be heated (e.g., an atomizer bomb) into the heating element 120. In the illustrated embodiment, the top portion 121a is tapered.

[0054] Optionally, the body 121b has a hollow cylindrical structure with both ends open. Of course, in other embodiments, the structure of the body 121b is not limited to the above and can also have other hollow structures. The body 121b has an inner surface 121c and an outer surface 121d. The inner surface 121c of the body encloses the hollow portion of the body 121b, and the outer surface 121d of the body is closer to the inner surface of the first shell 110.

[0055] Specifically, the vent 122 being located near the top 121a means that the vent 122 is located in an area on the body 121b near the top 121a, which is closer to the top 121a than the bottom of the body 121b near the first shell 110. Optionally, the vent 122 is located within the 0mm to 6mm area of the body 121b near the top 121a. Furthermore, the vent 122 is located within the 0mm to 4mm area of the body 121b near the top 121a. This study found that when the vent 122 is located within the 0mm to 4mm area of the body 121b near the top 121a, the burnt smell is less and the aroma is richer, resulting in a better overall taste.

[0056] Optionally, multiple vent holes 122 are spaced apart on the body 121b. Each vent hole 122 communicates with the hollow portion of the body 121b and the external space, forming an airflow channel for gas circulation. The multiple spaced-apart vent holes 122 are located within a 0 mm to 6 mm area of the body 121b near the top 121a. That is, the multiple spaced-apart vent holes 122 are located within the vent hole arrangement area of the body 121b, and the maximum distance from the bottom side of the vent hole arrangement area near the first shell 110 to the connection between the body 121b and the top 121a is 0 mm to 6 mm.

[0057] Specifically, in some embodiments, a plurality of mutually spaced vent holes 122 are arranged on the body 121b near the top 121a and around the central axis of the body 121b to be distributed in an annular shape, wherein the distance between the vent hole 122 closest to the top 121a and the connection between the top 121a and the body 121b is greater than 0 mm and less than 3 mm (e.g., 0.5 mm, 1 mm, 2 mm, or 2.5 mm), and the distance between the vent hole 122 farthest from the top 121a and the connection between the top 121a and the body 121b is greater than 3 mm and not more than 6 mm (e.g., 3.5 mm, 4 mm, 5 mm, or 6 mm). In a specific example, a plurality of mutually spaced vent holes 122 are arranged on the body 121b near the top 121a and around the central axis of the body 121b to be distributed in an annular shape, and the vent holes 122 are arranged in the middle area of the body 121b near the top 121a. For example, the distance between the vent hole 122 closest to the top 121a and the connection between the top 121a and the main body 121b is 3 mm, and the distance between the vent hole 122 farthest from the top 121a and the connection between the top 121a and the main body 121b is 4 mm. That is, the vent holes 122 are arranged within a range of 3 mm to 4 mm from the top 121a. 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 main body 121b, and the distance between the vent hole 122 farthest from the top 121a and the connection between the top 121a and the main body 121b are not limited to the above dimensions and can be adjusted according to actual conditions.

[0058] Of course, in another specific example, the plurality of vent holes 122 can be arranged in a ring around the central axis of the body 121b, that is, the plurality of vent holes 122 are arranged at a distance of 4 mm from the top 121a. It is understood that in other embodiments, the distance between the vent holes 122 and the top 121a is not limited to the aforementioned 4 mm, and can also be other sizes between 0 mm and 6 mm.

[0059] Furthermore, a plurality of vent holes 122 are provided in the 0 mm to 4 mm region of the main body 121b near the top 121a. It should be noted that, in this document, the distance between the vent hole 122 closest to the top 121a and the connection between the top 121a and the main body 121b refers to the minimum distance between the hole wall of the vent hole 122 closest to the top 121a and the connection between the top 121a and the main body 121b; the distance between the vent hole 122 farthest from the top 121a and the connection between the top 121a and the main body 121b refers to the maximum distance between the hole wall of the vent hole 122 farthest from the top 121a and the connection between the top 121a and the main body 121b.

[0060] In the illustrated embodiment, the plurality of vents 122 are arranged in an array, with the spacing between adjacent vents 122 being approximately equal. Of course, in other embodiments, the vents 122 are not limited to being arranged in an array with approximately equal spacing, and can be adjusted based on actual needs. It will be appreciated that in other embodiments, the plurality of vents 122 are not limited to being distributed in a ring around the central axis of the body 121b, and can be adjusted based on actual needs. For example, the plurality of vents 122 may be spaced and concentrated on one side of the body 121b, while the area opposite that side is devoid of vents 122.

[0061] It is understandable that the number of vents 122 is not limited to the multiple mentioned above, and there can also be only one, as long as it can connect the external space and the hollow part of the main body 121b. When there is one vent, the distance between the connection between the main body 121b and the top 121a and the vent 122 is 0mm to 6mm. Furthermore, the distance between the connection between the main body 121b and the top 121a and the vent 122 is 0mm to 4mm. This study found that when the distance between the connection between the main body 121b and the top 121a and the vent 122 is set to 0mm to 4mm, the burnt smell is less and the aroma is richer, and the overall taste is better.

[0062] In some embodiments, each vent 122 is a tapered hole, and the aperture of the section of each vent 122 close to the inner surface 121c of the body is larger than the aperture of the section close to the outer surface 121d of the body. By setting the aperture of the section of the vent 122 close to the inner surface 121c of the body to be larger than the aperture of the section close to the outer surface 121d of the body, the flow path of the air flow from the hollow part of the body 121b through the vent 122 is narrowed, so that the air flow out of the body 121b has a greater impact force, and the outer surface 121d of the body is less likely to adhere to or stick to dirt, thereby reducing dirt residue. In a specific example, each vent 122 is a tapered hole, and the aperture of each vent 122 gradually decreases from the middle space of the heating base 121 to the external space. In other embodiments, each vent 122 is a straight hole. Of course, the vent holes 122 are not limited to the straight through holes and tapered holes mentioned above, and may also be through holes of any other shapes.

[0063] Optionally, the cross-sectional area of the hollow portion of the body 121b accounts for 50% to 90% of the cross-sectional area of the body 121b. This arrangement allows the airflow to circulate more smoothly in the heating base 121. It should be noted that the cross-sectional area of the body 121b is the area of the figure enclosed by the projection of the outer surface 121d of the body on the plane perpendicular to the central axis of the body 121b, including the cross-sectional area of the hollow portion of the body 121b. Taking the body 121b as a hollow cylinder as an example, after the body 121b is cross-sectioned perpendicular to the central axis of the body 121b, a ring shape will be formed. The cross-sectional area of the hollow portion of the body 121b is the area of the inner circle of the ring, and the cross-sectional area of the body 121b is the area of the outer circle of the ring. In an optional specific example, the cross-sectional area of the hollow portion of the body 121b accounts for 60%, 70%, 75%, 80%, 85% or 90% of the cross-sectional area of the body 121b.

[0064] Specifically, each vent 122 has an air inlet located on the inner surface 121c of the body and an air outlet connected to the air inlet and located on the outer surface 121d of the body. In the illustrated embodiment, the vent 122 is a straight through hole, with the centerlines of the outlet and the air inlet collinear. The vent 122 extends perpendicularly to the extension of the body 121b, and the centerline of the air outlet is perpendicular to the centerline of the body 121b. In other embodiments, the vent 122 is oriented diagonally away from the top 121a of the body 121b, from the air inlet toward the air outlet. In this case, airflow flows toward the end of the body 121b away from the top 121a, allowing more airflow to flow through the atomizer bomb, thereby improving the utilization rate of the atomizer bomb. It is understood that in some embodiments, the air outlet of each vent 122 can also be positioned toward the tip. In this embodiment, the air outlets of each vent 122 are oriented in the same direction. It is understood that in other embodiments, the air outlets of the vents 122 may not be oriented in the same direction. For example, the air outlets of some of the vents 122 may be oriented perpendicular to the extension direction of the body 121b, while the air outlets of some of the vents 122 may be oriented toward an end of the body 121b away from the top 121a.

[0065] Optionally, the diameter of the vent hole 122 is 0.1 mm to 0.3 mm. In a specific example, the diameter of the vent hole 122 is 0.1 mm, 0.2 mm, or 0.3 mm.

[0066] Optionally, the outer surface area of the heating base 121 is 180 mm 2 ~360mm 2 The total area of each vent hole 122 on the outer surface of the body 121b is not less than 0.6mm 2The opening area of each vent hole 122 is 0.07~0.4mm 2 Furthermore, the outer surface area of the heating base 121 is 200 mm 2 ~260mm 2 The total area of each vent hole 122 on the outer surface of the body 121b is 0.6mm 2 ~2.4mm 2 .

[0067] In some embodiments, the heating element 120 further includes a protective layer 123 located on the outer surface of the heating base 121, and the protective layer 123 is also provided with air outlet holes 124 corresponding to and connected to each air vent 122. The air outlet holes 124 are connected to the air vents 122, so that the air outlet holes 124, the air vents 122 and the hollow portion of the main body 121b form an air flow channel. The protective layer 123 is used to protect the heating base 121, reduce the effect of dirt on the efficiency of heat generation by the heating element 120, and also reduce the effect of dirt on the taste of the atomized cartridge. In some embodiments, the direction of the air outlet holes 124 is the same as that of the air vents 122. Of course, in some other embodiments, the direction of the air outlet holes 124 may also be different from that of the air vents 122.

[0068] Optionally, protective layer 123 is a glass protective layer 123 or an infrared ceramic protective layer 123. Glass protective layer 123 resists dirt from adhering to its surface due to its anti-adhesion properties. Infrared ceramic protective layer 123 resists dirt from adhering to its surface by absorbing heat from heating element 120 through infrared ceramics. In one embodiment, protective layer 123 is a glass glaze layer.

[0069] In some embodiments, the heating element 120 further includes a temperature measurement circuit 125, which is located between the protective layer 123 and the heating base 121. The temperature measurement circuit 125 is used to provide feedback on the temperature of the heating base 121. In the illustrated embodiment, the temperature measurement circuit 125 is generally U-shaped, with the ends of the U-shaped temperature measurement circuit 125 away from the top 121a and the bottom close to the top 121a of the heating base 121. It will be understood that in other embodiments, the shape of the temperature measurement circuit 125 is not limited to the above, and may also be other shapes.

[0070] The above-mentioned heating element 120 has at least the following advantages: by providing an air vent 122 on the hollow main body 121b, and the air vent 122 connects the external space and the hollow part of the heating base 121 to form an air flow channel, thereby changing the air flow path during application, and then when the heating atomizer bullet of the heating element 120 is used, less burnt odor substances are inhaled and the aroma of the atomizer bullet is richer, and the taste is better.

[0071] In some embodiments, the heating assembly 10 further includes a fixing member 130, which is sleeved on the main body 121b of the heating element 120 and away from the top 121a of the heating element 120. The fixing member 130 is used to fix the heating element 120. Specifically, the fixing member 130 is located outside the first shell 110. In some embodiments, it is sleeved on the heating element 120. In an optional specific example, the fixing member 130 is a flange. Of course, in other embodiments, the fixing member 130 is not limited to a flange, and can also be other structures that can be used to fix the heating element 120.

[0072] The heating assembly 10 includes the heating element 120 and the first shell 110 , and has the corresponding advantages of the heating element 120 .

[0073] Also, see Figures 7 and 8 An embodiment of the present invention further provides another heating component 20, which is substantially the same as the above-mentioned heating component 10, except that the heating base 221 of the heating component 20 is in the form of a hollow sheet, and the main body 221b in this embodiment is in the form of a hollow sheet with openings at both ends.
