The heating element 42 heats and atomizes the atomized liquid in the liquid guide body 41. As can be understood, the heating atomizing assembly 4 is separated from the oil storage tank 5. The atomized liquid in the oil storage tank 5 is guided to the heating atomizing assembly 4 by the liquid guide assembly 3, which effectively avoids the occurrence of over-rapid oil filling, uneven oil filling, oil leakage, and insufficient atomization.

[0043] like Figure 4 As shown, in this embodiment, the housing 1 is a hollow columnar structure, which can be a cylindrical structure or a rectangular parallelepiped structure. Furthermore, the housing 1 can be made of a hard insulating material, such as phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, silicone resin, acrylic resin, etc. and modified resins thereof. Of course, the housing 1 can also be made of tubular metal, such as stainless steel, copper iron, aluminum, aluminum alloy and other metals and then electroplated on the surface. It can be understood that the material of the housing 1 can be selected and set according to actual needs and is not specifically limited here. Furthermore, the outer periphery of the housing 1 can be provided with textures to facilitate the user's grip.

[0044] In this embodiment, the upper shell 2 can be an interference fit, threaded connection, or snap-fit connection with the housing 1. An air hole 21 is provided at the top of the upper shell 2, and an air duct 22 extends downwardly from the periphery of the air hole 21.

The air duct 22 can be made of metal, such as a stainless steel tube.

[0045] Combine Figure 5 、 Figure 6 、 Figure 8 As shown, further, the liquid guiding seat 31 can be a roughly cylindrical structure, whose circumferential outer side surface abuts the inner circumferential surface of the casing 1. Furthermore, the upper surface of the liquid guiding seat 31 is recessed with a positioning groove 311, and one side of the positioning groove 311 passes through one side of the circumferential side surface of the liquid guiding seat 31.

[0046] The positioning groove 311 cooperates with the inner circumference of the housing 1 opposite thereto to form a first atomizing space A. The liquid guide 41 is detachably installed in the positioning groove 311 , and the heating element 421 is exposed in the first atomizing space A.

[0047] Furthermore, the positioning groove 311 may include a bottom surface 3111, a first side surface 3112 arranged in an annular manner on the bottom surface 3111, and a pair of second side surfaces 3113 arranged opposite to each other, wherein the first side surface 3112 is connected to the side of the second side surface 3113.

It also includes an opposite first surface and a second surface, wherein the first surface contacts the first side surface 3112, and the second surface forms an atomizing surface, and the heating element 421 is embedded in or attached to the atomizing surface. It can be understood that the liquid-guiding core 32 introduces the atomized liquid in the liquid storage chamber 5 into the liquid-guiding seat 31, and then introduces it into the liquid-guiding liquid 41 through the side surface of the positioning groove 311, and is heated and atomized into an aerosol by the heating element 421. Preferably, the liquid guide seat 31 and the liquid guide core 32 are an integral structure, and the liquid guide seat 31 and the liquid guide core 32 can be a single piece of cotton. In this embodiment, the bottom of the liquid guide core 32 contacts the inner bottom surface of the liquid storage tank 5. The end of the liquid guide core 32 can be in contact with the inner bottom surface of the liquid storage tank 5, or the length of the liquid guide core 32 can be greater than the height of the liquid storage tank 5. As a result, most of the bottom of the liquid guide core 32 contacts the inner bottom surface of the liquid storage tank 5, which can promote the atomized liquid at the bottom of the liquid storage tank 5 to be introduced into the heating atomizing assembly 4, avoiding burning or scorching due to insufficient oil and liquid supply.

[0048] In this embodiment, the liquid guide 41 is made of porous ceramic. It is understood that the material for making the liquid guide 31 can also be a porous material with a microporous capillary effect, such as foamed metal, porous glass, or hard fiberglass tube. Of course, the liquid guide 41 can also be liquid guide cotton, etc. Its structure and material can be selected according to needs and are not specifically limited here.

[0049] The material of the heating element 421 can be a metal material, metal alloy, graphite, carbon, conductive ceramic, or other ceramic and metal composite material with appropriate impedance.

The heating element 42 can be a heating wire bent into a disc shape or a grid-shaped heating sheet. The heating element 42 can be sintered into an integral structure with the liquid-conducting body 41 to be attached to the above-mentioned atomizing surface. In some embodiments, the above-mentioned heating element 42 can also be a heating circuit, heating track, heating coating or heating film formed on the atomizing surface of the liquid-conducting body 41. Its structural shape can be diverse and can be selected according to needs. The above-mentioned heating net, heating wire, heating sheet, heating circuit, heating track, heating coating or heating film are arranged corresponding to the atomizing surface, so that the distance between the atomizing surface and the heating element 42 is shortest, so that the atomized liquid such as tobacco oil can quickly reach the heating track for atomization.

[0053] In this embodiment, the liquid storage tank 5 is a columnar structure, which may be a cylindrical structure, with an inner cavity for storing atomized liquid. The liquid storage tank 5 may be a one-piece structure, provided with a through hole for the liquid guide core 32 to pass through.

[0054] Furthermore, the liquid storage tank 5 can be made of a hard insulating material, such as phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, silicone resin, acrylic resin, and modified resins thereof. Of course, the liquid storage tank 5 can also be made of metal, such as stainless steel, copper iron, aluminum, aluminum alloy, and other metals with surface electroplating. It is understood that the material of the liquid storage tank 5 can be selected and set according to actual needs and is not specifically limited here. Furthermore, the height of the liquid storage tank 5 is 5-80 mm. A height exceeding 80 mm or less than 5 mm may result in the risk of insufficient or excessive oil supply.

[0055] Combine Figure 4-Figure 7 As shown, further, the electronic atomization device includes a first seal 7 mounted on the lower part of the liquid storage chamber 5 and a second seal 8 disposed above the liquid guide seat 31, and the electrode 422 passes through the first seal 7 to be connected to the battery 6.

[0056] In this embodiment, the first sealing member 7 is a columnar structure, which may be a cylindrical structure, with its circumferential side surface abutting the inner circumferential surface of the housing 1. Furthermore, the first sealing member 7 has a bearing groove formed on its upper surface, which is sleeved on the bottom of the liquid storage chamber 5. Furthermore, the first sealing member 1 has a first annular protrusion 72 formed on its circumferential side surface for abutting the inner wall of the housing 1 to improve airtightness. The first sealing member 7 may be a silicone member.

[0057] Furthermore, the second sealing member 8 is a columnar structure, which may be a cylindrical structure, with its circumferential side surface abutting the inner circumferential surface of the housing 1. Furthermore, the lower surface of the second sealing member 8 abuts the surface of the liquid guide seat 31. Furthermore, the lower surface of the second sealing member 8 may be provided with a limiting groove, which is sleeved on a portion of the outer circumference of the upper portion of the liquid guide seat 3 to limit the position of the liquid guide seat 3. Furthermore, the circumferential side surface of the second sealing member 8 is provided with a second annular protrusion 82 for abutting the inner wall of the housing 1 to improve airtightness. The second sealing member 8 may be a silicone member.

[0058] Furthermore, the first sealing member 7 is provided with a first air inlet 71 passing through its upper and lower opposite surfaces, and the second sealing member 8 is provided with a first air outlet 81 passing through its upper and lower opposite surfaces. The first air inlet 71 and the first air outlet 81 are both arranged opposite to the first atomization space A. Preferably, the first air inlet 71 and the first air outlet 81 are coaxially arranged. Of course, they can also be staggered. One or more first air inlet holes 71 and the second air inlet holes 72 can be provided.

[0059] It can be understood that a first gap is left between the outer periphery of the liquid storage tank 5 and the inner wall of the casing 1, and the first air inlet 71, the first gap, the first atomization space A and the first air outlet 81 cooperate to form a first air flow channel. The external air flow brings out the aerosol in the first atomization space A through the first air flow channel for the user to enjoy.

[0060] Furthermore, the electronic atomizer device includes a base 9 housed within the opening of the housing 1. The base 9 includes a bottom wall 91 and an annular peripheral wall 92 disposed on the bottom wall 91. The bottom wall 91 is provided with an air inlet hole 911 extending through its upper and lower opposing surfaces. The base 9 and the housing 1 may be secured by an interference fit, a threaded connection, or a snap-fit connection. Various securing methods are possible and are not specifically limited herein.

[0061] Furthermore, predetermined gaps are left between the bottom surface of the battery 6 and the upper surface of the base 9, as well as between the circumferential side surfaces of the battery 6 and the inner periphery of the housing 1. The air intake holes and the predetermined gaps cooperate to form an air channel, which communicates with the first airflow channel at the front. In this embodiment, the battery 6 is secured to the housing 1 using adhesive 61, but can alternatively be secured using a bracket. A control motherboard, etc., may be provided on the battery 6. Example

[0062] like Figure 9 As shown, the electronic atomization device of the present invention includes a cylindrical housing 1a and an upper housing 2a connected to the housing 1a, and also includes a liquid guide component 3a housed in the housing 1a, a heating atomization component 4a, a liquid storage chamber 5a and a battery 6a connected to the heating atomization component 4a to provide power therefor.

[0063] The liquid guiding assembly 3a includes a liquid guiding seat 31a disposed above the liquid storage chamber 5a, and a liquid guiding core 32a connected to the liquid guiding seat 31a and extending into the liquid storage chamber 5a.

[0064] The heating atomization assembly 4a includes a liquid guide 41a and a heating element 42a connected to the liquid guide 41a. The liquid guide 41a is installed on the liquid guide seat 31a. The heating element 42a includes a heating body 421a embedded in or attached to the liquid guide 41a, and an electrode 422a having one end connected to the heating body 421a and the other end extending downward to connect to the battery 6a.

[0065] The liquid guide core 32a guides the atomized liquid in the liquid storage tank 5a to the liquid guide seat 31a and then to the liquid guide body 41a. The heating element 42a heats and atomizes the atomized liquid in the liquid guide body 41a. As will be appreciated, the heating atomizing assembly 4a is separated from the oil storage tank 5a. The liquid guide assembly 3a guides the atomized liquid in the oil storage tank 5a to the heating atomizing assembly 4a, effectively preventing over-rapid and uneven oil filling, as well as oil leakage and inadequate atomization.

[0066] In this embodiment, the housing 1a is a hollow cylindrical structure, which can be a cylindrical structure or a rectangular parallelepiped structure. Furthermore, the housing 1a can be made of a hard insulating material, such as phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, silicone resin, acrylic resin, etc. and modified resins thereof. Of course, the housing 1a can also be made of tubular metal, such as stainless steel, copper iron, aluminum, aluminum alloy, etc., and then electroplated on the surface. It is understandable that the material of the housing 1a can be selected and set according to actual needs and is not specifically limited here. Furthermore, the outer periphery of the housing 1a can be provided with textures to facilitate user gripping.

[0067] In this embodiment, the upper shell 2a can be an interference fit, threaded connection, or snap-fit connection with the housing 1a. An air hole 21a is provided at the top of the upper shell 2a, and an air duct 22a extends downwardly from the periphery of the air hole 21a. The housing 1a can be made of a rigid insulating material, such as phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, silicone resin, acrylic resin, or modified resins thereof. The air duct 22a can be made of metal, such as a stainless steel tube.

[0068] Furthermore, the liquid guide base 31a is generally a plate-shaped structure, and the liquid guide 41a is disposed on the liquid guide base 31a, with a gap between its circumferential side and the inner circumference of the housing 1a to form the second atomization space B. Alternatively, the liquid guide base 31a can be a plate-shaped structure with a slot provided therein, the slot having a height less than that of the liquid guide 41a, thereby limiting and fixing the liquid guide 41a, while leaving most of the liquid guide 41a exposed.

[0069] The liquid guiding liquid 41a is roughly a columnar structure, such as a cylindrical structure or a square structure. The bottom surface of the liquid guiding liquid 41a forms a liquid inlet surface, and part or all of its circumferential side surfaces form an atomizing surface. The heating element 421 is embedded or attached to the atomizing surface. The heating element 421a can be an arc structure or a flat structure. It can be understood that the liquid guiding core 32a guides the atomized liquid in the liquid storage chamber 5a into the liquid guiding seat 31a, and then into the liquid guiding liquid 41a, and is heated and atomized into an aerosol by the heating element 421a. Preferably, the liquid guiding seat 31a and the liquid guiding core 32a are an integrated structure, and the liquid guiding seat 31a and the liquid guiding core 32a can be an integrated cotton. In this embodiment, the bottom of the liquid-conducting core 32a contacts the inner bottom surface of the liquid storage tank 5a. The end portion may contact the inner bottom surface of the liquid storage tank 5a, or the length of the liquid-conducting core 32a may be greater than the height of the liquid storage tank 5a. Thus, most of the bottom of the liquid-conducting core 32a contacts the inner bottom surface of the liquid storage tank 5a, which can promote the introduction of the atomized liquid at the bottom of the liquid storage tank 5a into the heating atomizing component 4a, avoiding burning or scorching due to insufficient oil and liquid supply.

[0070] In this embodiment, the liquid guide 41a is made of porous ceramic. It is understood that the liquid guide 31a can also be made of porous materials with a microporous capillary effect, such as foamed metal, porous glass, or rigid fiberglass tubes. Of course, the liquid guide 41a can also be made of liquid guide cotton, etc. Its structure and material can be selected according to needs and are not specifically limited here.

The first and second conductive portions are arranged parallel to the heating portion to form a planar structure. The positive and negative electrodes 422a are connected to the first and second conductive portions, respectively.

[0073] Preferably, the first conductive portion, the second conductive portion, and / or the heating portion are provided with a hook portion embedded in the liquid-conducting body 41a. The hook portion is an L-shaped structure, which improves the fixing stability of the heating element 41a. It is understood that the heating element 421a can be an integral structure with the liquid-conducting body 41a, or can be printed on the liquid-conducting body 41a using a printing process. Its structure can be various and is not specifically limited here.

[0074] Of course, the heating element 42a can be a sheet-like heating net, and the heating element 42a is fixed on the atomizing surface of the liquid-conducting body 41a. The heating element 42a can be a heating wire bent into a disc or a grid-shaped heating sheet. The heating element 42a can be sintered into an integral structure with the liquid-conducting body 41a to be attached to the above-mentioned atomizing surface.
