Description

Technical Field

[0001] This invention relates to the field of electronic atomization, and in particular to a photothermal electronic atomization component, a light source component, and an electronic atomization device. Background Technology

[0002] Traditional electronic atomizing devices mainly rely on an atomizing core for heating and atomization. The atomizing core typically includes a liquid guide for conducting liquid and a heating element that is in contact with the liquid guide. The heating element is electrically connected to a power source and uses electricity as its energy source. By controlling the heat generated by the heating element, the liquid in the liquid guide is heated to its boiling point and evaporated into atomized vapor. It is currently widely used in the field of electronic cigarettes. Most of them currently use the thermal effect of the resistance of the heating element to convert electrical energy into heat energy to heat the atomized liquid and make it vaporize into vapor.

[0003] Resistance heating has several drawbacks, such as poor adhesion between the heating element and the liquid guiding component, leading to coil burn-in. Electronic atomizing devices used in e-cigarettes typically consist of an atomizing component and a power supply component. The atomizing coil is usually located within the atomizing component, and the combination of the atomizing component and the power supply component provides a conductive connection to supply power to the heating element. Poor conductivity can cause malfunctions. Furthermore, resistance heating elements are mostly made of metals or alloys, while e-cigarettes are consumables with high usage. After use, these metals and alloys are often discarded along with the atomizing component, resulting in waste and environmental pollution.

[0004] In addition, some electronic atomizing devices use light to irradiate the liquid guiding component to heat the atomizing liquid, but this also has some problems:

[0005] The atomized vapor produced by atomization, also known as aerosol, is formed by mixing atomized vapor at a certain temperature with air. Most of the atomized vapor flows out of the electronic atomizing device through the air outlet, while a small portion condenses upon encountering the cooler walls inside the electronic atomizing components, forming condensate droplets. Since electronic atomizing devices are typically used with the air outlet in a vertical orientation, and the light-emitting unit is also located on the vertical side of the liquid guide, the light path is easily blocked by condensate or splashed liquid particles during atomization, affecting the atomization effect. The condensate also causes light refraction, blocking and scattering the light propagation, leading to changes in the size and shape of the light spot acting on the liquid guide, resulting in inconsistent heat generation.

[0006] Therefore, designing a new heating method to overcome the above-mentioned defects has become an urgent problem to be solved. Summary of the Invention

The light source component includes a second substrate and a light-emitting unit disposed on the second substrate. In the state where the light source component and the electronic atomizing component are combined, the light-emitting unit is located on one side of the light-transmitting hole in the second direction.

[0043] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention.

[0044] See Figure 1-3In one embodiment of the present invention, a photothermal electronic atomizing component 1 includes a first substrate 11 and a liquid guiding component 12 disposed on the first substrate 11 for storing and conducting liquid. The first substrate 11 is provided with an atomizing chamber 1121, an air outlet 1112, a light-transmitting hole 1123, and a vent 1124. The air outlet 1112 is arranged along a first direction 31, with one end connected to the atomizing chamber 1121 and the other end connected to the outside of the electronic atomizing component 1. The light-transmitting hole 1123 is opened along a second direction 32 and connects the outside of the electronic atomizing component 1 with the atomizing chamber 1121. The liquid guiding component 1... 2 includes an atomizing surface 121, which is exposed in the atomizing cavity 1121 and is located at a position corresponding to the light-transmitting hole 1123 along the second direction 32. A vent 1124 is connected to the atomizing cavity 1121 so that light from outside the electronic atomizing component 1 can pass through the light-transmitting hole 1123 along the second direction 32 to irradiate and heat the atomizing surface 121 of the liquid guiding component 12 to generate atomized vapor. The airflow passes through the vent 1124, the atomizing cavity 1121 and the air outlet 1112 in sequence, carrying the atomized vapor into the air outlet 1112 along the first direction 31. The first direction 31 and the second direction 32 intersect each other and are not parallel to each other.

[0045] The electronic atomizing component 1 utilizes light to generate heat. Specifically, the liquid guiding component 12 conducts and stores the atomizing liquid. Light from outside the electronic atomizing component 1 (e.g., light emitted from the light-emitting unit 22 of the light source component 2) shines through the light-transmitting hole 1123 along the second direction 32 onto the liquid guiding component 12, generating heat and heating the atomizing liquid on the liquid guiding component 12 to its boiling point to evaporate and produce atomized vapor. Compared with the conventional electronic atomizing component 1 of the prior art, the atomizing component of the present invention has the following beneficial technical effects:

[0046] ① The atomizing liquid comes into contact with fewer substances (only with the first substrate 11 and the liquid-conducting material, unlike the traditional resistance heating method in the background art, which involves contact with metal or alloy heating elements), thus avoiding contact with metal conductors and making it safer.

[0047] ② The electronic atomization component 1 does not have a resistive heating element. The electronic atomization component 1 does not need to be electrically connected to the light source component 2 to supply power to the heating element. Therefore, there is no need to consider the issue of conductive contact between the electronic atomization component 1 and the light source component 2, resulting in a lower failure rate.

[0048] ③ Since the electronic atomization component 1 does not have a resistive heating element, its structure is simpler, it has fewer components, and its cost is reduced (for electronic atomization components 1 used in electronic cigarettes, electronic atomization components 1 are consumables, and reducing this part of the components greatly reduces the cost of use).

[0049] ④ The atomization effect is more stable and reliable. It does not require a stable combination of heating element and liquid guide 12. The atomizing liquid on the liquid guide 12 is directly heated by light, and there is no problem of core clogging due to poor adhesion between the heating element and the liquid guide 12.

[0050] ⑤ The atomized vapor produced by atomization is also called aerosol, which is formed by a mixture of atomized vapor with a certain temperature and air. The electronic atomization component 1 of the present invention takes into account that when the atomized vapor encounters the lower temperature wall surface inside the electronic atomization component 1, condensation will occur, and it will gather into condensate droplets. Since the electronic atomization component 1 is usually used in the longitudinal state of the air outlet 1112 after being combined with the light source component 2, that is, the first direction 31 is longitudinal, if the direction of the vent 1124 is also along the first direction 31, then the direction of light illumination is usually also along the first direction 31. It is easy for the light path to be blocked by condensate or liquid particles splashed during atomization, which will affect the atomization effect. The condensate will cause light to refract, blocking and scattering the propagation of light, which will cause changes in the size and shape of the light spot acting on the liquid guide 12, resulting in uneven heat. Therefore, in the electronic atomizing component 1 of the present invention, on the one hand, the air outlet 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32. The direction of the light path is different from that of the air outlet 1112, so that the light path is not easily blocked by the condensate. On the other hand, after the airflow enters the atomizing chamber 1121 along the first direction 31 through the light-transmitting hole 1123, it carries the hot atomized vapor to form an aerosol and enters the air outlet 1112 along the second direction 32. The atomized aerosol particles are not easily blocked by the light path. On the other hand, the atomizing liquid usually adheres to the inner wall between the electronic atomizers, and the light-transmitting hole 1123 can allow the light to avoid the condensate.

[0051] The liquid guiding component 12 is generally made of porous or fibrous materials, such as non-woven fabric, flax fiber cloth, aramid cloth and other fibrous filaments. It can also be a porous material in solid form, such as porous ceramic, porous glass, porous metal (since it does not need to be used in combination with a conductive heating element and does not need to be powered, metal can also be used), or a combination of these materials.

[0052] Vent 1124 is opened along the second direction 32 and is on the same side of the first substrate 11 as light-transmitting hole 1123; one end of air outlet 1112 is connected to atomizing chamber 1121 and the other end is connected to the outside of electronic atomizing component 1, so that airflow first enters atomizing chamber 1121 along the second direction 32 through vent 1124, and then enters air outlet 1112 along the first direction 31. Vent 1124 is on the same side of the first substrate 11 to facilitate the design of the optical and air paths of electronic atomizing component 1 and light source component 2 (described below).

[0053] The vent 1124 is also the light-transmitting hole 1123, thus the vent 1124 is also the path of light. In this way, there is no wall on the light path, and no condensate will adhere to the wall, affecting the propagation of light; or the vent 1124 and the light-transmitting hole 1123 are separate holes, in which case the airflow and light pass through different holes. The light-transmitting hole 1123 and the liquid-guiding atomizing surface 121 are respectively located on opposite sides of the atomizing chamber 1121.

[0054] The first substrate 11 includes a first main body 111 and a first assembly part 112 extending outward on the first main body 111 for assembly with external components (e.g., light source assembly 2). The first substrate 11 has a first assembly space 110 for arranging the light-emitting unit 22 of the light source assembly 2 at a position corresponding to the light-transmitting hole 1123. The first assembly space 110 is located outside the atomizing chamber 1121 in the second direction 32. The atomizing chamber 1121 and the liquid guiding member 12 are disposed in the first assembly part 112. The light-transmitting hole 1123 is disposed on the side wall of the first assembly part 112 facing the first assembly space 110. The air outlet 1112 is disposed in the first main body 111.

[0055] In the second direction 32, the size of the first assembly part 112 is smaller than the size of the first main body part 111. The side wall of the first main body part 111 in the first direction 31 and the side wall of the first assembly part 112 in the second direction 32, which is provided with a vent hole 1124, define the first assembly space 110.

[0056] Preferably, the first assembly portion 112 protrudes outward from the first main body portion 111 along the first direction 31 for insertion with an external component.

[0057] The outer side of the first substrate 11 is provided with a first anti-mistake step 114 that is inclined relative to the first direction 31 to prevent mistakes when the electronic atomizing component 1 is combined with an external component, such as the light source component 2. For example, the first anti-mistake step 114 prevents mistakes when the electronic atomizing component 1 is plugged into the light source component 2.

[0058] The first main body 111 has a storage chamber 1111 for storing atomizing liquid, and the first assembly 112 has a partition 1120. The partition 1120 divides the internal space of the first assembly 112 into an atomizing chamber 1121 and an inlet chamber 1122 that communicates with the storage chamber 1111 for storing atomizing liquid. In other words, the atomizing chamber 1121 is provided on the first assembly 112; the partition 1120 has a connection between the atomizing chamber 1121 and the inlet chamber 1122. Mounting hole 11200, liquid guide 12 is disposed in the first assembly part 112 and mounted on mounting hole 11200. Liquid guide 12 includes liquid inlet surface 122 exposed in liquid inlet chamber 1122 for allowing atomized liquid to enter the liquid guide. Atomized chamber 1121 and liquid storage chamber 1111 are respectively disposed on both sides of the first direction 31 of partition part 1120, so that after the atomized liquid in liquid storage chamber 1111 enters liquid inlet chamber 1122, it enters liquid guide 12 through liquid inlet surface 122.

[0059] The first main body 111 has a liquid storage chamber 1111 that communicates with the liquid inlet chamber 1122. The electronic atomizing component 1 is a consumable and serves to store atomizing liquid, form a channel for atomizing vapor, and accommodate the liquid guide 12.

[0060] The first substrate 11 includes a liquid guiding seal 13, which is disposed between the liquid guiding member 12 and the mounting hole 11200, so that the atomizing chamber 1121 and the liquid inlet chamber 1122 are sealed, and the atomized liquid in the liquid inlet chamber 1122 will not enter the atomizing chamber 1121.

[0061] See Figure 4-8 According to one embodiment of the present invention, a light-heating type light source assembly 2 includes a second substrate 21 and a light-emitting unit 22 disposed on the second substrate 21. The second substrate 21 includes a second main body 211 and a second assembly portion 212 disposed on one side of the second main body 211 in a first direction 31. A second assembly space 210 for mounting an external component is provided on one side of the second assembly portion 212 in a second direction 32. The light-emitting unit 22 is disposed on the second assembly portion 212 and irradiates light toward the second assembly space 210 along the second direction 32. The first direction 31 and the second direction 32 intersect each other but are not parallel to each other.

[0062] The light source component 2 of the present invention can be used in combination with the above-mentioned electronic atomizing component 1 to provide illumination to the electronic atomizing component 1 and use light to heat and atomize. Specifically, when the light source component 2 is combined with the electronic atomizing component 1, the portion of the electronic atomizing component 1 with the light-transmitting hole 1123 is disposed in the second combination space 210. The light from the light-emitting unit 22 of the power supply device shines through the light-transmitting hole 1123 along the second direction 32 and irradiates the atomizing surface 121 of the liquid guiding component 12, causing the atomized liquid to heat up and atomize.

[0063] The second substrate 21 includes a housing 213. The size of the second assembly part 212 in the second direction 32 is smaller than the size of the second main body part 211. The second main body part 211 and the second assembly part 212 are disposed in the housing 213. The second main body part 211, the second assembly part 212 and the housing 213 define a second assembly space 210. The second assembly space 210 is open to one side in the first direction 31 so that the first preparation of the electronic atomizing component 1 can enter the second assembly space 210 and the second assembly part 212 can enter the first assembly space 110 to realize the combination of the electronic atomizing component 1 and the light source component 2. In this state, the light-transmitting hole 1123 is located on one side in the second direction 32 of the light-emitting unit 22.

[0064] The electronic atomizing component 1 is a consumable, serving to store the atomizing liquid, act as a channel for forming atomized vapor, and accommodate the liquid guide 12. The light source component 2 converts electrical energy into light energy, which in turn converts the light energy into heat energy, using the heat energy to heat the atomizing liquid in the atomizing component.

[0065] The light source assembly 2 includes a heat sink 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 has an air inlet 214 communicating with the outside. The heat sink 23 is thermally conductively connected to the light-emitting unit 22 (e.g., through direct contact or by a thermally conductive material). The heat sink 23 is located on the second assembly 212 and has multiple heat dissipation grooves 231. These grooves connect the air inlet 214 to the outside of the light source assembly 2. The heat sink 23 primarily dissipates heat from the light-emitting unit 22, preventing damage due to excessive temperature during use. It is generally made of a metal with high thermal conductivity, such as aluminum, aluminum alloy, or copper. Its large surface area contacts the light-emitting unit 22, and multiple heat dissipation grooves 231 allow gas to pass through and carry away heat. Specifically, on the one hand, the heat dissipation groove 231 increases the contact area between the heat dissipation component 23 and the air, improving the heat dissipation effect. On the other hand, when the electronic atomizing component 1 and the light source component 2 are combined, external air flows sequentially through the air inlet duct 214, the heat dissipation groove 231, the vent 1124, the atomizing chamber 1121, and the air outlet duct 1112. First, the airflow carries away the heat from the heat dissipation component 23, achieving heat dissipation of the light-emitting unit 22. Then, the airflow enters the atomizing chamber 1121, carrying atomized vapor into the air outlet duct 1112. Preferably, the heat dissipation component 23 is located on the side of the light-emitting unit 22 facing away from the light-emitting side in the second direction 32, and the heat dissipation groove 231 is opened along the first direction 31.

[0066] The second assembly slot 210 is an insertion hole that opens to one side in the first direction 31 for the first assembly part 112 of the electronic atomizing component 1 to be inserted; the light-emitting unit 22 and / or heat sink 23 are provided on one side of the second assembly slot 210 in the second direction 32.

[0067] The outer side of the second substrate 21 is provided with a second anti-mistake step 215 that is inclined relative to the first direction 31 to prevent mistakes when the light source assembly 2 is combined with an external component (e.g., the electronic atomizing assembly 1). For example, the second anti-mistake step 215 prevents mistakes when the electronic atomizing assembly 1 is plugged into the light source assembly 2.

[0068] The light source assembly 2 also includes a battery 24 disposed on the second substrate 21 for supplying power to the light-emitting unit 22.

[0069] See Figure 9-15 According to one embodiment of the present invention, a photothermal electronic atomizing device includes the aforementioned light source assembly 2 and the aforementioned electronic atomizing assembly 1, which is detachably combined with the light source assembly 2. The light source assembly 2 includes a second substrate 21 and a light-emitting unit 22 disposed on the second substrate 21. When the light source assembly 2 and the electronic atomizing assembly 1 are combined, the light-emitting unit 22 is located on one side of the light-transmitting hole 1123 in the second direction 32. The light-emitting unit 22 emits light along the second direction 32 toward the light-transmitting hole 1123, so that the light from the light-emitting unit 22 irradiates and heats the atomizing surface 121 of the liquid guiding component 12 along the second direction 32 through the light-transmitting hole 1123 to generate atomized vapor. In other words, the light-emitting unit 22, the light-transmitting hole 1123, and the atomizing surface 121 of the liquid guiding component 12 are all in the second direction 32 and are in a straight line. This ensures that the light energy is concentrated on the liquid guiding component 12, and at the same time, there is no obstruction in the path of the light, so that the light cannot be blocked and will not be unable to concentrate on the liquid guiding cotton to generate heat. At the same time, this design also has the advantage that the lack of obstruction can prevent condensation from accumulating on the wall, while condensation on the path of light will refract the light and cause the light energy to be dispersed.

[0070] This electronic atomizing device utilizes light to generate heat. Specifically, the liquid guiding component 12 conducts and stores the atomized liquid. When the electronic atomizing component 1 and the light source component 2 are combined, the light emitted by the light-emitting unit 22 of the light source component 2 shines through the light-transmitting hole 1123 along the second direction 32 onto the liquid guiding component 12, generating heat and heating the atomized liquid on the liquid guiding component 12 to its boiling point to evaporate and produce atomized vapor. Compared with conventional electronic atomizing devices in the prior art, the atomizing device of the present invention has the following beneficial technical effects:

[0071] ① The atomizing liquid comes into contact with fewer substances (only with the first substrate 11 and the liquid-conducting material, unlike the traditional resistance heating method in the background art, which involves contact with metal or alloy heating elements), thus avoiding contact with metal conductors and making it safer.

[0072] ② The electronic atomization component 1 does not have a resistive heating element. The electronic atomization component 1 does not need to be electrically connected to the light source component 2 to supply power to the heating element. Therefore, there is no need to consider the issue of conductive contact between the electronic atomization component 1 and the light source component 2, resulting in a lower failure rate.

[0073] ③ Since the electronic atomization component 1 does not have a resistive heating element, its structure is simpler, it has fewer components, and its cost is reduced (for electronic atomization components 1 used in electronic cigarettes, electronic atomization components 1 are consumables, and reducing this part of the components greatly reduces the cost of use).

[0074] ④ The atomization effect is more stable and reliable. It does not require a stable combination of heating element and liquid guide 12. The atomizing liquid on the liquid guide 12 is directly heated by light, and there is no problem of core clogging due to poor adhesion between the heating element and the liquid guide 12.

[0075] The first substrate 11 includes a first main body 111 and a first assembly part 112 extending outward from the first main body 111 for combination with external components (e.g., light source assembly 2). The first substrate 11 has a first assembly space 110 for setting the light-emitting unit 22 of the light source assembly 2 at the position corresponding to the light-transmitting hole 1123. The first assembly space 110 is located outside the atomizing chamber 1121 in the second direction 32. The atomizing chamber 1121 and the liquid guide 12 are disposed in the first assembly part 112. The light-transmitting hole 1123 is disposed on the side wall of the first assembly part 112 facing the first assembly space 110. The air outlet 1112 is disposed in the first main body 111. When the electronic atomizing assembly 1 and the light source assembly 2 are combined, the first assembly part 112 is disposed in the second assembly space 210, and the second assembly part 212 is disposed in the first assembly space 110.

[0076] The outer side of the first substrate 11 is provided with a first anti-mistake step 114 that is inclined relative to the first direction 31, and the outer side of the second substrate 21 is provided with a second anti-mistake step 215 that is inclined relative to the first direction 31 and matches the first anti-mistake step 114; when the electronic atomizing component 1 and the light source component 2 are combined, the first anti-mistake step 114 and the second anti-mistake step 215 abut against each other.

[0077] The light source assembly 2 includes a heat sink 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 has an air inlet 214 that connects to the outside. The heat sink 23 and the light-emitting unit 22 are thermally conductively connected (e.g., they are directly in contact or connected by some thermally conductive material). The heat sink 23 is provided on the second assembly 212. The heat sink 23 has multiple heat dissipation slots 231 that connect the air inlet 214 to the outside of the light source assembly 2. When the electronic atomizing assembly 1 and the light source assembly 2 are combined, the air inlet 214, heat dissipation slots 231, vent 1124, atomizing chamber 1121 and air outlet 1112 are connected to each other so that the airflow can carry away the heat from the heat sink 23, thereby dissipating heat from the light-emitting unit 22. The airflow enters the atomizing chamber 1121 and carries the atomized vapor into the air outlet 1112.

[0078] For the aforementioned electronic atomizing component 1, light source component 2, or electronic atomizing device, please refer to... Figure 11 The first direction 31 is inclined relative to the second direction 32, or see Figure 10 The first direction 31 is perpendicular to the second direction 32.

[0079] In this invention, the light-emitting unit 22 refers to an element that can generate light when powered on. The light-emitting unit 22 of the electronic atomization device may include a light-emitting body 221 for emitting light and a condenser lens 222 connected to the light-emitting body 221 for focusing the light onto the atomization surface 121 of the liquid guide 12. Heat is generated by the light focusing of the light-emitting unit 22. Specifically, a high-power LED light source, incandescent lamp light source, halogen lamp light source, infrared heating lamp light source, or single-mode laser source, multi-mode laser source, semiconductor laser source, laser, etc., integrated with the condenser lens 222 can be used. Among them, the light-emitting unit 22 that emits infrared light is preferred. Specifically, the light-emitting unit 22 is provided with concave and convex mirrors or reflective materials, which can make the light emitted by the light-emitting body 221 focus in one direction or at one point.

[0080] In the electronic atomization device of the present invention, the light from the light-emitting unit 22 is focused onto the liquid guiding component 12 to form a light spot, which heats the atomized liquid on the liquid guiding component 12. The size of the light spot is generally 2*2mm or φ2mm in diameter, and is not limited here. If the power is high and the atomization volume is required, the power of the light-emitting component and the size of the light spot can be appropriately increased.

[0081] The number of light-emitting units 22 can be multiple, such as multiple lasers. The light emitted by the light-emitting unit 22 has a single wavelength and relatively concentrated energy, and a relatively high heat concentration.

[0082] The electronic atomizing component 1 and electronic atomizing device of the present invention utilize light to heat the atomized liquid. Light is a form of energy, and there are many examples of using light to generate heat in daily life, such as using a magnifying glass to focus light to ignite matches and wood, using microwave ovens for cooking, using high-power lasers to cut metal, and using lasers for welding. With technological advancements, light-generated heat is being used in many specialized industries. Previous electronic atomizing devices also required converting electrical energy into heat energy for heating and atomizing liquids. Therefore, the application of this technology to the electronic atomizing component 1 and electronic atomizing device of the present invention has a very high feasibility. Furthermore, with technological advancements, the light-emitting focusing module can be made very small; for example, the core light-emitting unit 22 can be as small as 4*4*2mm. The atomization temperature required for the liquid is only around 200 degrees Celsius, and a 3-8W light-emitting unit 22, after focusing the light, can achieve this temperature. Therefore, the feasibility is very high.

[0083] When the electronic atomizing device of the present invention is in use, the airflow enters the light source assembly 2 through the opening of the air inlet 214 at the bottom of the light source assembly 2, passes through the air inlet 214, then passes through the heat dissipation groove 231 of the heat sink 23, and then flows in through the vent hole 1124 of the electronic atomizing assembly 1, enters the atomizing chamber 1121, passes through the atomizing surface 121 of the liquid guide 12, the airflow carries the atomized vapor, then enters the air outlet 1112, and finally flows out of the electronic atomizing assembly 1.

[0084] In summary, the electronic atomization component 1, the light source component 2, and the electronic atomization device of the present invention have at least the following beneficial technical effects:

[0085] ① The atomizing liquid comes into contact with fewer substances (only with the first substrate 11 and the liquid-conducting material, unlike the traditional resistance heating method in the background art, which involves contact with metal or alloy heating elements), thus avoiding contact with metal conductors and making it safer.

[0086] ② The electronic atomization component 1 does not have a resistive heating element. The electronic atomization component 1 does not need to be electrically connected to the light source component 2 to supply power to the heating element. Therefore, there is no need to consider the issue of conductive contact between the electronic atomization component 1 and the light source component 2, resulting in a lower failure rate.

[0087] ③ Since the electronic atomization component 1 does not have a resistive heating element, its structure is simpler, it has fewer components, and its cost is reduced (for electronic atomization components 1 used in electronic cigarettes, electronic atomization components 1 are consumables, and reducing this part of the components greatly reduces the cost of use).

[0088] ④ The atomization effect is more stable and reliable. It does not require a stable combination of heating element and liquid guide 12. The atomizing liquid on the liquid guide 12 is directly heated by light, and there is no problem of core clogging due to poor adhesion between the heating element and the liquid guide 12.

[0089] ⑤ The atomized vapor produced by atomization is also called aerosol, which is formed by a mixture of steam and air at a certain temperature. The electronic atomization component 1 of the present invention takes into account that when the steam encounters the lower temperature wall surface inside the electronic atomization component 1, it will condense and gather into condensate droplets. If light shines on the condensate, the condensate will cause refraction, blocking and scattering the propagation of light, which will cause changes in the size and shape of the light spot acting on the liquid guide 12, resulting in uneven heat. Since the electronic atomization component 1 is usually used in the longitudinal state of the air outlet 1112 after being combined with the light source component 2 (that is, the first direction 31 is longitudinal), if the direction of the vent 1124 is also along the first direction 31, the direction of light illumination will usually also be along the first direction 31. It is easy for the light path to be blocked by the condensate or the liquid particles splashed during atomization, affecting the atomization effect. Therefore, in the electronic atomizing component 1 of the present invention, on the one hand, the air outlet 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32. The direction of the light path is different from that of the air outlet 1112, so that the light path is not easily blocked by the condensate. On the other hand, after the airflow enters the atomizing chamber 1121 along the first direction 31 through the light-transmitting hole 1123, it carries the hot atomized vapor to form an aerosol and enters the air outlet 1112 along the second direction 32. The atomized aerosol particles are not easily blocked by the light path. On the other hand, the atomizing liquid usually adheres to the inner wall between the electronic atomizers, and the light-transmitting hole 1123 can allow the light to avoid the condensate.

[0090] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
