[0001] This utility model relates to the field of heating technology for smoking devices, and in particular to an atomizer. Background Technology

[0002] Currently, when using e-cigarettes, heating wires are typically used to heat the e-liquid or e-sodium in the e-liquid chamber to achieve the atomization effect. However, the heating wires are usually exposed to the air, which can cause high-temperature oxidation during heating. On the other hand, the heat generated by the heating wires can be lost too quickly (resulting in high power consumption) and the temperature of the outer wall of the atomizer can become too high. Utility Model Content

[0003] The main purpose of this invention is to propose an atomizer that aims to improve the problems of the heating wire being easily oxidized, losing heat quickly, and consuming too much power in current atomizers.

[0004] To achieve the above objectives, this utility model proposes an atomizer having a Z-direction extending along its height direction, comprising: The cup body has a storage cavity formed on one side along the Z direction, and the storage cavity is used to store the substance to be atomized; A sealed cavity is provided within the cup body; and A heating element, housed within the sealed cavity, is used to heat the material to be atomized within the storage cavity; the sealed cavity includes: A first cavity is disposed outside the storage cavity and surrounds the storage cavity; in the Z direction, the first cavity at least partially overlaps with the storage cavity; and In the Z direction, the second cavity is spaced apart on one side of the storage cavity, and the second cavity is in communication with the first cavity.

[0005] In one embodiment, the sealing cavity is located outside the storage cavity, and the sealing cavity surrounds the storage cavity; In the Z direction, the sealing cavity is at least partially overlapped with the storage cavity.

[0006] In one embodiment, the heating element includes: A heating element, wherein the heating element is disposed within the first cavity, and at least one end of the heating element along the Z-direction is located within the second cavity; and A conductive element is at least partially housed within the second cavity and electrically connected to one end of the heating element that extends into the second cavity; the end of the conductive element away from the heating element extends outward from the second cavity into the cup body for connection to an external power source.

[0007] In one embodiment, the heating element includes: Insulating structural member, the insulating structural member being arranged in a tubular shape; and A heating wire is disposed on the outer and / or inner peripheral side of the insulating structural member, and the heating wire is electrically connected to the conductive member to generate heat when the conductive member is energized.

[0008] In one embodiment, the cup body includes: A first cup portion, the first cavity and the storage cavity are both formed within the first cup portion, and the second cavity is at least partially formed within the first cup portion; and The second cup portion is connected to the first cup portion, and the second cavity is formed at the end of the second cup portion away from the storage cavity.

[0009] In one embodiment, the second cup portion includes: In the Z-direction, the arc-shaped portion has a large-diameter end and a small-diameter end, the large-diameter end being connected to the first cup portion; and A straight portion is provided on the side of the arc-shaped portion away from the first cup portion, and the straight portion is connected to the small diameter end.

[0010] In one embodiment, in the Z direction, an opening is formed on the side of the first cup portion away from the second cup portion, and the storage cavity communicates with the outside through the opening.

[0012] In one embodiment, the sealing cavity is provided under negative pressure.

[0013] This atomizer features a sealed cavity within the cup body, housing the heating element within this cavity. This allows the heating element to heat and atomize the e-liquid or e-cream stored within the cavity. Because the heating element is within the sealed cavity and isolated from the external environment, it avoids high-temperature oxidation caused by contact with air during heating of the e-liquid or e-cream. This prevents increased resistance, reduced heating efficiency, and shortened lifespan due to high-temperature oxidation. Furthermore, the sealed cavity minimizes heat loss, reducing power consumption and contributing to energy conservation. Attached Figure Description

[0021] Currently, when using e-cigarettes, heating wires are typically used to heat the e-liquid or e-soak in the e-liquid chamber to achieve atomization. However, the heating wire is usually exposed to air, which leads to high-temperature oxidation during heating. This high-temperature oxidation forms an oxide layer on the surface of the heating wire, increasing resistance. With a constant voltage, increased resistance means decreased current, resulting in reduced heating power. At the same time, the formation of the oxide layer hinders heat conduction, as heat must pass through the oxide layer to be transferred to the e-liquid or e-soak, increasing thermal resistance. Furthermore, it can cause the heat generated by the heating wire to dissipate too quickly (leading to higher power consumption) and cause the outer wall temperature of the atomizer to become too high.

[0022] Based on this, refer to Figures 1-6 As shown, this application provides an atomizer with a Z-direction extending along its height. The atomizer includes a cup body 1 and a heating element 2. A storage cavity 3 is formed on one side of the cup body 1 along the Z-direction. The storage cavity 3 is used to store the substance to be atomized, which may be e-liquid or e-soap. A sealed cavity 4 is disposed inside the cup body 1, and its internal environment is isolated from the outside. The heating element 2 is housed in the sealed cavity 4 and is used to heat the e-liquid or e-soap in the storage cavity 3, thereby producing an atomization effect.

[0023] In this embodiment, by placing the heating element 2 inside the sealed cavity 4 and isolating it from the external environment, the heating element 2 will not come into contact with the air in the external environment when heating the e-liquid or e-oil in the storage cavity 3. This avoids high-temperature oxidation and extends the service life of the heating element 2. Since high-temperature oxidation is avoided, no oxide layer will form on the surface of the heating element 2 during operation, which can significantly improve heating efficiency.

[0024] In this embodiment, the heating element 2 is disposed in the sealed cavity 4 to heat and atomize the e-liquid or e-soap in the storage cavity 3. This reduces the rate at which the heat generated by the heating element 2 dissipates to the outside. Since the heating element 2 is housed in the sealed cavity 4 and does not directly contact the external environment, there is no direct heat conduction path between the heating element 2 and the external environment. This significantly reduces the rate at which heat is transferred to the outside through the wall of the cup body 1. Furthermore, there is no air flow in the sealed cavity 4, so there is no thermal convection. Heat cannot be transferred to the outside through air convection, thereby reducing heat loss.

[0025] It is understandable that in this solution, the sealed cavity 4 can be filled with inert gas or the sealed cavity 4 can be evacuated to a certain degree of vacuum, so that there is no oxygen in the environment inside the sealed cavity 4, thereby completely eliminating the situation of high-temperature oxidation of the heating element 2 during operation.

[0026] Reference Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment of this application, the sealing cavity 4 is located outside the storage cavity 3 and surrounds the storage cavity 3; thereby, the heat generated by the heating element 2 during operation can be transferred and diffused from any position on the periphery of the storage cavity 3 into the storage cavity 3, thereby improving the heating effect of the e-liquid or e-sodium in the storage cavity 3 and ensuring the uniformity of heating of the e-liquid or e-sodium.

[0027] It is understandable that, in the Z direction, the sealing cavity 4 is at least partially overlapped with the storage cavity 3, thereby shortening the distance between the storage cavity 3 and the heating cavity and reducing the heat transfer path, thereby accelerating the heat transfer speed into the storage cavity 3 and improving the heating atomization effect.

[0028] Reference Figure 3 , Figure 5 As shown, in one embodiment of this application, the sealing cavity 4 includes a first cavity 41 and a second cavity 42; wherein, the first cavity 41 is disposed outside the storage cavity 3, and the first cavity 41 surrounds the storage cavity 3; it can be understood that, as Figure 3 As shown, the first cavity 41 and the storage cavity 3 can be coaxially spaced or disaxially spaced within the cup body 1. When coaxially spaced, it helps to evenly transfer the heat generated by the heating element 2 to the storage cavity 3, thereby improving the uniformity of heating of the e-liquid or e-sodium in each area of ​​the storage cavity 3. Preferably, this solution adopts the arrangement of the first cavity 41 and the storage cavity 3 being coaxially spaced. Figure 3 , Figure 5As shown, in the Z direction, the first cavity 41 at least partially overlaps with the storage cavity 3, thereby shortening the heat transfer path between the first cavity 41 and the storage cavity 3, which can accelerate the speed of heat transfer into the storage cavity 3 and improve heating efficiency.

[0029] In one embodiment of this application, in the Z direction, the second cavity 42 is spaced apart on one side of the storage cavity 3, and the second cavity 42 and the first cavity 41 are connected to form the aforementioned sealed cavity 4. For example, in the Z direction, the projection of the storage cavity 3 can be made to fall within the projection range of the second cavity 42, that is, the storage cavity 3 is wrapped by the second cavity 42 along the Z direction, while the first cavity 41 is arranged in a ring. Thus, through the cooperation of the first cavity 41 and the second cavity 42, the periphery and the side along the Z direction of the storage cavity 3 are wrapped and covered, thereby enabling the heat generated by the heating element 2 to be transferred into the storage cavity 3 from more paths and directions, thereby improving the heating speed.

[0030] Reference Figure 3 , Figure 4 As shown, in one embodiment of this application, the heating element 2 includes a heating tube 21 and a conductive element 22; wherein, the heating tube 21 is a hollow tubular structure (when powered, it can generate heat, thereby achieving the effect of heating the e-liquid or e-soap in the storage cavity 3), and is inserted into the first cavity 41; it can be understood that the heating tube 21, the first cavity 41, and the storage cavity 3 are all coaxially arranged. In order to further improve the heating rate, the inner surface of the heating tube 21 can be as close as possible to the side wall of the first cavity 41 near the storage cavity 3, so that the heat generated by the heating tube 21 can be quickly transferred to the storage cavity 3 to improve the heating efficiency.

[0031] It is understood that, in the Z direction, the heating element 21 is at least partially located within the second cavity 42, so that the heat generated by this portion of the heating element 21 can be transferred from one side of the storage cavity 3 along the Z direction into the storage cavity 3, thereby further improving the heating efficiency.

[0032] In this embodiment, the conductive element 22 is housed in the second cavity 42 and is electrically connected to one end of the heating tube 21 that extends into the second cavity 42. At least part of the end of the conductive element 22 away from the heating tube 21 extends outward from the cup body 1 from the second cavity 42 for connection with an external power source (power supply component), thereby enabling power supply to the heating tube 21 and achieving the heating effect.

[0033] Understandably, the conductive element 22 consists of two conductive metal wires, one for introducing current and the other for leading it out, thus forming an electrical circuit with the heating element 21 to supply power to the heating element 21. One end of the metal wire is fixedly connected to the heating element 21 within the second cavity 42. Since the metal wire passes through the wall of the cup 1 when it extends outward from the second cavity 42, a hole needs to be provided inside the wall of the cup 1 for the metal wire to pass through, to ensure that the external... Air will not enter the sealed cavity 4 through the aforementioned holes. High-temperature resistant sealant (such as epoxy resin sealant, silicone sealant, etc.) can be filled or injected into the aforementioned holes. At the same time, the metal wire is fixedly bonded to the hole through the filling of the aforementioned sealant. The heating tube 21 is fixedly connected to one end of the metal wire in the second cavity 42, thereby fixing the heating tube 21 in the sealed cavity 4. It can be understood that a separate fixing component can also be set in the sealed cavity 4 to fix the heating tube 21.

[0034] Reference Figure 6 As shown, in one embodiment of this application, the heating element 21 includes an insulating structure 211 and a heating wire 212. The insulating structure 211 is tubular, and the heating wire 212 is provided on the outer or inner circumferential surface of the insulating structure 211 (the heating wire 212 is a common electric heating element; when current passes through the heating wire 212, electrons and atoms inside the conductor collide, thereby generating heat). The density of the heating wire 212 on the outer circumferential surface of the insulating structure 211 can be determined according to actual needs. It is understood that the heating wire 212 has a first end and a second end that are arranged opposite to each other along its length. The first end is used to be electrically connected to one of the metal wires, and the second end is used to be electrically connected to the other metal wire, thereby realizing the introduction and extraction of external current, so that the heating wire 212 is energized and generates heat for heating.

[0035] In this embodiment, the insulating structural component 211 can be a ceramic structure, which has a high melting point, good thermal stability and chemical stability, and can withstand high temperatures and maintain structural integrity; at the same time, ceramic materials also have good insulation properties to avoid short circuits and leakage.

[0036] It is understandable that the arrangement of the heating wire 212 on the surface of the insulating structure 211 can be set arbitrarily, but it should be arranged as evenly as possible to ensure the uniformity of heating, thereby achieving relatively uniform heating of the e-liquid or e-oil in the storage cavity 3.

[0037] Reference Figure 1 , Figure 2As shown, in one embodiment of this application, the cup body 1 includes a first cup portion 11 and a second cup portion 12; wherein, a first cavity 41 and a storage cavity 3 are both formed in the first cup portion 11, and a second cavity 42 is at least partially formed in the first cup portion 11; in the Z direction, the second cup portion 12 is connected to the first cup portion 11, thereby forming the aforementioned sealing cavity 4 between the first cup portion 11 and the second cup portion 12; one end of the second cavity 42 away from the storage cavity 3 is formed in the second cup portion 12.

[0038] Reference Figure 4 , Figure 5 As shown, in one embodiment of this application, the second cup portion 12 includes an arc-shaped portion 121 and a straight portion 122. In the Z direction, the arc-shaped portion 121 has a large-diameter end and a small-diameter end. That is, the end of the second cavity 42 away from the storage cavity 3 extends in a gradually narrowing trend. Because the distance between this area and the storage cavity 3 gradually increases, and the heating tube 21 no longer extends into this area, the cross-section of the end of the second cavity 42 away from the storage cavity 3 is set to gradually narrow, which can reduce the volume size of the cup 1, thereby reducing its space occupation and helping to achieve miniaturization of the overall structure size of the atomizer.

[0039] In this embodiment, the straight portion 122 is connected to the small-diameter end, and in the Z direction, the projections of the straight portion 122 and the small-diameter end coincide; as Figure 3 , Figure 4 As shown, the conductive element 22 is inserted into the straight portion 122 and extends outward from the cup body 1 through the straight portion 122. That is, the hole for the metal wire to pass through is provided in the straight portion 122.

[0040] Reference Figure 1 , Figure 5 As shown, in one embodiment of this application, in the Z direction, an opening 111 is formed on the side of the first cup portion 11 away from the second cup portion 12. The storage cavity 3 is connected to the outside through the opening 111, thereby allowing the gas generated after the e-liquid or e-oil in the storage cavity 3 is heated and atomized to be transmitted and transported to the outside through the opening 111.

[0041] In one embodiment of this application, the cup body 1 is a glass structural component, such as quartz glass. The main component of quartz glass is silicon dioxide, which is chemically very stable and hardly reacts with other acidic substances. It also has high temperature resistance, allowing the quartz glass container to withstand high-temperature environments and ensure the stability of e-liquid or e-cigarette during the heating process. In addition, quartz glass has good electrical insulation properties, maintaining stable electrical insulation characteristics even at high temperatures. This allows quartz glass to effectively prevent safety hazards such as leakage when used in devices that require electric heating, such as electronic cigarettes.

[0042] In one embodiment of this application, in order to further improve the protection effect on the heating element 2, the sealing cavity 4 can be evacuated to a certain degree of vacuum to remove the air inside and completely prevent the heating element 2 from contacting the air. At the same time, since the sealing cavity 4 is in a certain degree of vacuum environment, it helps to achieve heat preservation and insulation, which reduces the efficiency of heat loss to the outside (reduces power consumption) and also avoids the surface temperature of the outer wall of the cup 1 from being too high.

[0043] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
