Abstract
Description
Technical Field
[0001] The present invention relates to the field of electronic atomization, and particularly to a photoheating type electronic atomization assembly, a light source assembly, and an electronic atomization device.
Background Art
[0002] Conventional electronic atomization devices mainly perform heating and atomization by an atomization core. Usually, the atomization core includes a liquid guiding member for guiding liquid, and a heating member in contact with the liquid guiding member. The heating member is electrically connected to a power source and uses electricity as an energy source. The method of controlling the generation of heat by the heating member to heat the liquid of the liquid guiding member to the boiling point and evaporate it into atomized vapor is currently widely used in the field of electronic cigarettes. At present, most of them utilize the thermal effect of the resistance of the heating member to convert electrical energy into thermal energy, and heat and vaporize the atomization liquid to form vapor.
[0003] There are several drawbacks to resistance heating. For example, Heating element When the adhesion to the liquid guiding member is inappropriate, coking of the core becomes a problem. Also, usually, an electronic atomization device used for electronic cigarettes includes an atomization assembly and an electrical supply assembly that are combined with each other. Usually, the atomization core is provided in the atomization assembly. When the atomization assembly and the electrical supply assembly are combined, a conductive connection is achieved and electricity is supplied to the heating member, but if there is a problem with the conductive connection, an abnormality occurs. Furthermore, most of the resistive heating members are made of materials such as metals or alloys, but electronic cigarettes belong to consumables and have a large usage amount. When an electronic cigarette is used up, these metals and alloys are often discarded together with the atomization assembly, resulting in waste and environmental pollution.
[0004] In addition, there are also electronic atomization devices that irradiate light on the liquid guiding member to heat the atomization liquid, but there are still several problems as follows.
[0005] The atomized vapor generated by atomization is also called an aerosol. This is formed by mixing atomized vapor, which has a certain temperature, with air. Most of the atomized vapor flows out of the electronic atomizer through the exhaust duct, but a small amount of atomized vapor condenses when it encounters the relatively low-temperature walls inside the electronic atomization assembly, and gathers to form condensed droplets. Normally, electronic atomizers are used with the exhaust duct oriented vertically, and since the light-emitting unit is also located on one side of the liquid guide member in the vertical direction, the path of light is easily blocked by the condensed liquid or liquid particles scattered during atomization, which impairs the atomization effect. The condensed liquid causes refraction of light rays, blocking and dispersing the propagation of light, which changes the size and shape of the spot acting on the liquid guide member, leading to the problem of uneven heat distribution.
[0006] Therefore, designing a new heating method that overcomes the aforementioned shortcomings is a pressing issue that needs to be addressed urgently. [Overview of the project] [Problems that the invention aims to solve]

[0029] Refer to Figures 1 to 3, which show a photothermal electron atomization assembly 1 in one embodiment of the present invention. The electron atomization assembly 1 includes a first base 11 and a fluid guide member 12 provided on the first base 11 for storing and conducting liquid. The first base 11 is provided with an atomization chamber 1121, an exhaust passage 1112, a light-transmitting hole 1123, and a ventilation hole 1124. The exhaust passage 1112 is provided along a first direction 31, with one end communicating with the atomization chamber 1121 and the other end communicating with the outside of the electron atomization assembly 1. The light-transmitting hole 1123 is opened along a second direction 32, connecting the outside of the electron atomization assembly 1 with the atomization chamber 1121. The fluid guide member 12 includes an atomizing surface 121. The atomizing surface 121 is exposed inside the atomization chamber 1121 and is provided in the second direction 32 at a position corresponding to the light-transmitting hole 1123. Electric External light rays from the atomizing assembly 1 pass through the light-transmitting holes 1123 along the second direction 32, irradiating and heating the atomizing surface 121 of the liquid guide member 12 to generate atomized vapor. The ventilation hole 1124 is in communication with the atomization chamber 1121. The airflow passes sequentially through the vent 1124, the atomization chamber 1121, and the exhaust passage 1112, causing the atomized steam to enter the exhaust passage 1112 along the first direction 31. Note that the first direction 31 and the second direction 32 are not parallel to each other, but intersect.
[0030] The electron atomizing assembly 1 generates heat using light. Specifically, the fluid guide member 12 conducts and stores the atomizing liquid. Light from outside the electron atomizing assembly 1 (for example, light rays emitted from the light-emitting unit 22 of the light source assembly 2) passes through the light-transmitting holes 1123 along the second direction 32, irradiating the fluid guide member 12 and generating heat. Then, atomizing vapor is generated by heating the atomizing liquid on the fluid guide member 12 to its boiling point and evaporating it. Conventional electron atomizing assemblies in the background art Ri In contrast, the present invention Electronic atomization assembly 1 It has the following beneficial technical effects:
[0031] (1) The atomizing liquid has few substances in contact with it (first substrate 11 and fluid guide member It is safer because it only comes into contact with the heating element and does not come into contact with metal or alloy heating elements as in conventional resistance heating methods in the background technology, thus avoiding contact with metal conductors.
[0032] (2) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the electron atomization assembly 1 does not need to supply electricity to a heating element through a conductive connection with the light source assembly 2. Therefore, there is no need to consider the issue of conductive contact between the electron atomization assembly 1 and the light source assembly 2, and the abnormality rate is lower.
[0033] (3) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the structure is simpler, the number of components is fewer, and the cost is reduced (in the case of the electron atomization assembly 1 used in e-cigarettes, the electron atomization assembly 1 is a consumable item, so reducing the number of components in this part significantly reduces the cost of use).
[0034] (4) The atomization effect becomes more stable and reliable. Since the atomizing liquid on the liquid guide member 12 is directly heated by light irradiation without requiring stability of the bond between the heating member and the liquid guide member 12, Heating element There is no problem of the core burning due to improper contact between the fluid guide member 12 and the core.
[0035] (5) The atomized vapor generated by atomization is also called an aerosol. This is formed by mixing atomized vapor having a certain temperature with air. The electronic atomization assembly 1 of the present invention takes into consideration that when the atomized vapor encounters the relatively low-temperature wall surface inside the electronic atomization assembly 1 again, condensation occurs and it gathers together to form condensed droplets. Normally, after the electronic atomization assembly 1 is combined with the light source assembly 2, the exhaust passage 1112 is oriented vertically, that is, the first direction 31 is oriented vertically. Transparent hole 1123 If the opening direction is also the first direction 31, then normally the direction of light irradiation will also be the first direction 31. In this case, the path of light is easily blocked by the condensate or liquid particles scattered during atomization, which hinders the atomization effect. The condensate causes a refraction phenomenon in the light, blocking and dispersing the propagation of light, which changes the size and shape of the spot acting on the liquid guide member 12, leading to the problem of uneven heat distribution. Therefore, in the electronic atomization assembly 1 of the present invention, the exhaust passage 1112 is provided along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32. By making the direction of the light path and the exhaust passage 1112 different, the light path is less likely to be obstructed by the condensate. Also, the airflow is 2nd direction 32 After entering the atomizing chamber 1121 from the light-transmitting hole 1123 along the way, it forms an aerosol accompanied by hot atomized vapor, 1st direction 31 It enters the exhaust passage 1112 along this line. This makes it less likely for atomized aerosol particles to block the path of light. Also, normally, Condensate teeth Electronic atomization assembly 1 Because it adheres to the inner wall, the light rays can avoid the condensate through the translucent pores 1123.
[0036] Generally, the fluid guide member 12 is made of a porous material or a fibrous material, and may be a fibrous material such as nonwoven fabric, linen fabric, or aramid fabric, or a solid porous material such as porous ceramic, porous glass, or porous metal (metal may be used as it does not need to be used in combination with a conductive heating element and does not require an electrical supply), or a combination of these materials.
[0037] The ventilation holes 1124 are provided along the second direction 32 and in the first base 11 Transparent hole 1123 It is located on the same side as the other. The exhaust passage 1112 has one end communicating with the atomization chamber 1121 and the other end communicating with the outside of the electronic atomization assembly 1. As a result, the airflow first enters the atomization chamber 1121 from the vent hole 1124 along the second direction 32, and then enters the exhaust passage 1112 along the first direction 31. Translucent pores 1123 and Ventilation hole 1124 but By being located on the same side of the first substrate 11, the design of the optical path and airflow path for the electron atomization assembly 1 and the light source assembly 2 (described later) becomes easier.
[0038] By making the ventilation hole 1124 a light-transmitting hole 1123, the ventilation hole 1124 also becomes a path for light. In this case, since there is no wall in the light path, the condensate will not adhere to the wall and affect the propagation of light. Alternatively, if the ventilation hole 1124 and the light-transmitting hole 1123 are separate holes, the airflow and light rays will pass through different holes. fluid guide member 12 The atomizing surfaces 121 are provided on opposite sides of the atomizing chamber 1121.
[0039] The first base 11 includes a first main body 111 and a first combination part 112 provided on the first main body 111, extending outward and being combined with an external assembly (e.g., a light source assembly 2). A first combination space 110 for arranging the light-emitting unit 22 of the light source assembly 2 is provided in the first base 11 at a position corresponding to the light-transmitting hole 1123. The first combination space 110 is located outside the atomizing chamber 1121 in the second direction 32. The atomizing chamber 1121 and the fluid guide member 12 are provided within the first combination part 112. The light-transmitting hole 1123 is provided in the side wall of the first combination part 112 facing the first combination space 110. The exhaust passage 1112 is provided in the first main body 111.
[0040] In the second direction 32, the size of the first combination portion 112 is smaller than the size of the first main body portion 111. The side wall of the first main body portion 111 in the first direction 31 and the side wall of the first combination portion 112 in the second direction 32, which is provided with the ventilation holes 1124, define the first combination space 110.
[0041] Preferably, the first combination portion 112 protrudes outward from the first main body portion 111 along the first direction 31 and is used for insertion with an external assembly.
[0042] On the outside of the first base body 11, there is a first poka-yoke step 114 that is inclined with respect to the first direction 31 and is used as a poka-yoke when the electron atomization assembly 1 is combined with an external assembly such as the light source assembly 2. For example, when the electron atomization assembly 1 and the light source assembly 2 are inserted into each other, the first poka-yoke step 114 provides poka-yoke protection.
[0043] The first main body 111 is provided with a liquid storage chamber 1111 for storing atomizing liquid. The first combination section 112 is provided with a dividing section 1120. The dividing section 1120 divides the internal space of the first combination section 112 into an atomizing chamber 1121 and a liquid supply chamber 1122 used for storing atomizing liquid and communicating with the liquid storage chamber 1111. In other words, the atomizing chamber 1121 is provided in the first combination section 112. The dividing section 1120 is provided with a mounting hole 11200 that connects the atomizing chamber 1121 and the liquid supply chamber 1122. The liquid guide member 12 is provided in the first combination section 112 and is attached to the mounting hole 11200. The liquid guide member 12 is exposed in the liquid supply chamber 1122 and supplies the atomizing liquid fluid guide member 12 Includes a liquid supply surface 122 for allowing liquid to enter. Atomization chamber 1121 and Liquid supply chamber 1122 These are provided on both sides of the first direction 31 of the divided section 1120. As a result, the atomizing liquid in the liquid storage chamber 1111 enters the liquid supply chamber 1122 and then enters the liquid guide member 12 via the liquid supply surface 122.
[0044] A liquid storage chamber 1111 is provided inside the first main body 111, which communicates with the liquid supply chamber 1122. The electronic atomization assembly 1 is a consumable item and has the functions of storing the atomizing liquid, forming a path for atomizing vapor, and housing the liquid guide member 12.
[0045] The first base body 11 includes a fluid seal member 13. The fluid seal member 13 is provided between the fluid seal member 12 and the mounting hole 11200. This seals the space between the atomization chamber 1121 and the liquid supply chamber 1122, preventing the atomizing liquid in the liquid supply chamber 1122 from entering the atomization chamber 1121.
[0046] Refer to Figures 4 to 8. The photoheated light source assembly 2 in one embodiment of the present invention includes a second base 21 and a light-emitting unit 22 provided on the second base 21. The second base 21 includes a second main body 211 and a second combination part 212 provided on one side of the second main body 211 in the first direction 31. A second combination space 210 for arranging an external assembly is provided on one side of the second combination part 212 in the second direction 32. The light-emitting unit 22 is provided on the second combination part 212. The light-emitting unit 22 irradiates a light ray toward the second combination space 210 along the second direction 32. Note that the first direction 31 and the second direction 32 are not parallel to each other but intersect.
[0047] The light source assembly 2 of the present invention is combined with the electron atomization assembly 1 to irradiate the electron atomization assembly 1 with light, thereby enabling heating and atomization by light. Specifically, when the light source assembly 2 and the electron atomization assembly 1 are combined, the portion of the electron atomization assembly 1 provided with the light-transmitting holes 1123 is placed within the second combination space 210. Light rays from the light-emitting unit 22 pass through the light-transmitting holes 1123 along the second direction 32 and are irradiated onto the atomization surface 121 of the liquid guide member 12, thereby raising the temperature of the atomization liquid and causing it to atomize.
[0048] The second base 21 includes a housing 213. The size of the second combination portion 212 in the second direction 32 is smaller than the size of the second main body portion 211. The second main body portion 211 and the second combination portion 212 are provided within the housing 213. The second main body portion 211, the second combination portion 212, and the housing 213 define a second combination space 210. The second combination space 210 is open toward one side in the first direction 31. This allows the electron atomizing assembly 1 to First combination section 112 The second combination space 210 enters the second combination part 212, and the second combination part 212 enters the first combination space 110, thereby realizing the combination of the electron atomization assembly 1 and the light source assembly 2. In this state, the light-transmitting hole 1123 is located on one side of the light-emitting unit 22 in the second direction 32.
[0049] The electronic atomization assembly 1 is a consumable item and has the functions of storing the atomizing liquid, forming a path for atomized vapor, and housing the liquid guide member 12. The light source assembly 2 converts electrical energy into light energy, converts the light energy into thermal energy, and heats the atomizing liquid in the atomization assembly with the thermal energy.
[0050] The light source assembly 2 includes a heat dissipation member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is also provided with an air supply passage 214 that communicates with the outside. The heat dissipation member 23 is connected to the light-emitting unit 22 in a way that allows heat to conduct (for example, they are connected in direct contact or connected via some heat-conducting material). The heat dissipation member 23 is provided in the second combination section 212. The heat dissipation member 23 is provided with a plurality of heat sinks 231. The heat sinks 231 communicate the air supply passage 214 with the outside of the light source assembly 2. The heat dissipation member 23 is mainly used to dissipate heat from the light-emitting unit 22, thereby preventing damage to the light-emitting unit 22 due to excessive temperature rise during use. Generally, the heat dissipation member 23 is made of aluminum, or an aluminum alloy, or copper, etc. Heat conductionIt is made of a metal material with excellent properties. The heat dissipation member 23 has a large surface area in contact with the light-emitting unit 22. The heat dissipation member 23 is also provided with multiple heat sinks 231 for transporting heat by passing gas through it. Specifically, the heat sinks 231 increase the contact area between the heat dissipation member 23 and the air, thereby improving the heat dissipation effect. When the electronic atomization assembly 1 and the light source assembly 2 are combined, the outside air passes sequentially through the air supply passage 214, the heat sinks 231, the vent holes 1124, the atomization chamber 1121, and the exhaust passage 1112. First, the airflow transports the heat from the heat dissipation member 23, thereby achieving heat dissipation of the light-emitting unit 22. After that, the airflow enters the atomization chamber 1121 and enters the exhaust passage 1112 accompanied by atomized steam. Preferably, the heat dissipation member 23 is provided on the side of the light-emitting unit 22 opposite to the light-emitting side in the second direction 32. Furthermore, the heatsink 231 is provided along the first direction 31.
[0051] The second combination space 210 is an insertion hole that opens toward one side in the first direction 31 and is used to insert the first combination portion 112 of the electron atomization assembly 1. The light-emitting unit 22 and / or heat dissipation member 23 are provided on one side of the second combination space 210 in the second direction 32.
[0052] On the outside of the second base body 21, there is a second poka-yoke step 215 that is inclined with respect to the first direction 31 and is used for poka-yoke when the light source assembly 2 and the external assembly (e.g., the electron atomization assembly 1) are combined. For example, when the electron atomization assembly 1 and the light source assembly 2 are inserted into each other, poka-yoke is performed by the second poka-yoke step 215.
[0053] The light source assembly 2 further includes a battery 24 provided on the second substrate 21 for supplying electricity to the light-emitting unit 22.
[0054] Refer to Figures 9 to 15. The photothermal electron atomizing device in one embodiment of the present invention includes the light source assembly 2 and the electron atomizing assembly 1 which is detachably combined with the light source assembly 2. The light source assembly 2 includes a second base 21 and a light-emitting unit 22 provided on the second base 21. When the light source assembly 2 and the electron 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 a light ray toward the light-transmitting hole 1123 along the second direction 32. As a result, the light from the light-emitting unit 22 passes through the light-transmitting hole 1123 along the second direction 32, irradiating and heating the atomizing surface 121 of the liquid guide member 12 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 guide member 12 are all located in a straight line in the second direction 32. This ensures that the light energy is focused onto the fluid guide member 12. Furthermore, because the light path is blocked, the blocking of light rays prevents... fluid guide member 12 This design prevents the situation where heat generation becomes impossible due to the focusing of light rays. Furthermore, this design has the added advantage of avoiding the situation where condensate accumulates on the walls due to the absence of obstruction, and the condensation along the light path causes refraction of the light rays, resulting in the dispersion of light energy.
[0055] The aforementioned electronic atomizing device generates heat using light. Specifically, the fluid guide member 12 conducts and stores the atomizing liquid. When the electronic atomizing assembly 1 and the light source assembly 2 are combined, light from the light-emitting unit 22 of the light source assembly 2 passes through the light-transmitting holes 1123 along the second direction 32, irradiating the fluid guide member 12 and generating heat. The atomizing liquid on the fluid guide member 12 is then heated to its boiling point and evaporated, generating atomized vapor. Compared to conventional electronic atomizing devices in the background art, the atomizing device of the present invention has the following beneficial technical effects.
[0056] (1) The atomizing liquid has few substances in contact with it (first substrate 11 and fluid guide member 12It is safer because it only comes into contact with the heating element and does not come into contact with metal or alloy heating elements as in conventional resistance heating methods in the background technology, thus avoiding contact with metal conductors.
[0057] (2) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the electron atomization assembly 1 does not need to supply electricity to a heating element through a conductive connection with the light source assembly 2. Therefore, there is no need to consider the issue of conductive contact between the electron atomization assembly 1 and the light source assembly 2, and the abnormality rate is lower.
[0058] (3) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the structure is simpler, the number of components is fewer, and the cost is reduced (in the case of the electron atomization assembly 1 used in e-cigarettes, the electron atomization assembly 1 is a consumable item, so reducing the number of components in this part significantly reduces the cost of use).
[0059] (4) The atomization effect becomes more stable and reliable. Since the atomizing liquid on the liquid guide member 12 is directly heated by light irradiation without requiring stability of the bond between the heating member and the liquid guide member 12, Heating element There is no problem of the core burning due to improper contact between the fluid guide member 12 and the core.
[0060] The first base 11 includes a first main body 111 and a first combination part 112 provided on the first main body 111, extending outward and being combined with an external assembly (e.g., a light source assembly 2). A first combination space 110 for arranging the light-emitting unit 22 of the light source assembly 2 is provided in the first base 11 at a position corresponding to the light-transmitting hole 1123. The first combination space 110 is located outside the atomizing chamber 1121 in the second direction 32. The atomizing chamber 1121 and the fluid guide member 12 are provided within the first combination part 112. The light-transmitting hole 1123 is provided in the side wall of the first combination part 112 facing the first combination space 110. The exhaust passage 1112 is provided in the first main body 111. With the electron atomization assembly 1 and the light source assembly 2 assembled, the first combination unit 112 is placed in the second combination space 210, and the second combination unit 212 is placed in the first combination space 110.
[0061] The outside of the first base body 11 is provided with a first poka-yoke step 114 inclined with respect to the first direction 31, and the outside of the second base body 21 is provided with a second poka-yoke step 215 that is inclined with respect to the first direction 31 and conforms to the first poka-yoke step 114. When the electron atomization assembly 1 and the light source assembly 2 are combined, the first poka-yoke step 114 and the second poka-yoke step 215 come into contact with each other.
[0062] The light source assembly 2 includes a heat dissipation member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is also provided with an air supply passage 214 that communicates with the outside. The heat dissipation member 23 is connected to the light-emitting unit 22 in a way that allows heat to conduct (for example, they are connected in direct contact or connected via some heat-conducting material). The heat dissipation member 23 is provided in the second combination section 212. The heat dissipation member 23 is provided with a plurality of heat sinks 231. The heat sinks 231 communicate the air supply passage 214 and the outside of the light source assembly 2. When the electronic atomization assembly 1 and the light source assembly 2 are combined, the air supply passage 214, heat sinks 231, vents 1124, atomization chamber 1121 and exhaust passage 1112 are in communication. As a result, the airflow transports the heat from the heat dissipation member 23, thereby achieving heat dissipation from the light-emitting unit 22. The airflow then enters the atomization chamber 1121 and, accompanied by atomized steam, enters the exhaust passage 1112.
[0063] In the electron atomization assembly 1, light source assembly 2, or electron atomization device described above, referring to Figure 11, the first direction 31 is inclined with respect to the second direction 32. Alternatively, referring to Figure 10, the first direction 31 is perpendicular to the second direction 32.
[0064] The light-emitting unit 22 is a component capable of generating light after power is applied. The light-emitting unit 22 of the electronic atomizing device in the present invention may include a light-emitting body 221 for emitting a light ray and a focusing lens 222 connected to the light-emitting body 221 for focusing the light ray onto the atomizing surface 121 of the liquid guide member 12, thereby generating heat by focusing the light from 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 light source, multi-mode laser light source, semiconductor laser light source, laser device, etc., with an integrated focusing lens 222 can be used, but it is preferable to select a light-emitting unit 22 that emits infrared rays. Specifically, the light-emitting unit 22 has a concave-convex lens or a light-reflecting material built in, making it possible to focus the light emitted by the light-emitting body 221 in one direction or to one point.
[0065] In the electronic atomizing device of the present invention, light from the light-emitting unit 22 is focused onto the liquid guide member 12 to form a spot, which heats the atomizing liquid on the liquid guide member 12. Generally, the size of the spot is 2*2 mm or φ2 mm in diameter, but this is not limited to that. Oh, fog When the demand for the amount of chemicals is high, Light-emitting unit 22 The output and spot size may be appropriately improved.
[0066] The number of light-emitting units 22 may be multiple; for example, they may be multiple laser devices. The light emitted from the light-emitting units 22 has a single wavelength and relatively concentrated energy, resulting in a relatively high degree of heat concentration.
[0067] The electronic atomization assembly 1 and electronic atomization device in the present invention heat and atomize a liquid for atomization using light. Light is a type of energy, and there are many examples in daily life where light is used to generate heat. For example, focusing light with a magnifying glass to light a match or wood, using a far-infrared oven for cooking, cutting metal with a high-power laser, or welding with a laser all use light to generate heat. Furthermore, with advances in technology, heat generation using light is widely used in some specialized industries. On the other hand, conventional electronic atomization devices also need to convert electrical energy into thermal energy for heating and atomizing liquids. Therefore, the feasibility of using the technology of the present invention in the electronic atomization assembly 1 and electronic atomization device is very high. Moreover, with advances in technology, the light emission and focusing modules can be made very small. For example, the core light emission unit 22 can be 4*4*2mm. Since the temperature required to atomize the atomizing liquid is only slightly over 200 degrees Celsius, this temperature can be achieved by focusing the light with a 3-8W light-emitting unit 22. Therefore, it is highly feasible.
[0068] In the present invention, during use, the electronic atomizing device allows airflow to enter the light source assembly 2 through the opening of the air supply passage 214 at the bottom of the light source assembly 2. After passing through the air supply passage 214 and the heat sink 231 of the heat dissipation member 23, the airflow flows in through the ventilation hole 1124 of the electronic atomizing assembly 1 and enters the atomizing chamber 1121, passing through the atomizing surface 121 of the liquid guide member 12. Subsequently, the airflow, accompanied by atomized vapor, enters the exhaust passage 1112 and finally flows out to the outside of the electronic atomizing assembly 1.
[0069] In summary, the electron atomization assembly 1, light source assembly 2, and electron atomization device of the present invention have at least the following beneficial technical effects.
[0070] (1) The atomizing liquid has few substances in contact with it (first substrate 11 and fluid guide member It is safer because it only comes into contact with the heating element and does not come into contact with metal or alloy heating elements as in conventional resistance heating methods in the background technology, thus avoiding contact with metal conductors.
[0071] (2) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the electron atomization assembly 1 does not need to supply electricity to a heating element through a conductive connection with the light source assembly 2. Therefore, there is no need to consider the issue of conductive contact between the electron atomization assembly 1 and the light source assembly 2, and the abnormality rate is lower.
[0072] (3) Since the electron atomization assembly 1 does not contain a heating element that generates resistive heat, the structure is simpler, the number of components is fewer, and the cost is reduced (in the case of the electron atomization assembly 1 used in e-cigarettes, the electron atomization assembly 1 is a consumable item, so reducing the number of components in this part significantly reduces the cost of use).
[0073] (4) The atomization effect becomes more stable and reliable. Since the atomizing liquid on the liquid guide member 12 is directly heated by light irradiation without requiring stability of the bond between the heating member and the liquid guide member 12, Heating element There is no problem of the core burning due to improper contact between the fluid guide member 12 and the core.
[0074] (5) The atomized vapor generated by atomization is also called an aerosol. This is formed by mixing vapor and air having a certain temperature. In the electronic atomization assembly 1 of the present invention, it is considered that when the vapor encounters the relatively low-temperature wall surface inside the electronic atomization assembly 1 again, condensation occurs and it gathers together to form condensed droplets. When light is irradiated onto the condensed liquid, the condensed liquid causes refraction, blocking and dispersing the propagation of light, which leads to a problem where the size and shape of the spot acting on the liquid guide member 12 changes, resulting in uneven heating. Normally, the electronic atomization assembly 1 is used after being combined with the light source assembly 2 with the exhaust passage 1112 oriented vertically (i.e., with the first direction 31 as the vertical direction). Transparent hole 1123 If the opening direction is also the first direction 31, then normally the direction of light irradiation is also the first direction 31. In this case, the light path is easily blocked by the condensate or liquid particles scattered during atomization, which hinders the atomization effect. Therefore, in the electronic atomization assembly 1 of the present invention, the exhaust passage 1112 is provided along the first direction 31, and the light-transmitting holes 1123 are opened along the second direction 32. By making the direction of the light path and the exhaust passage 1112 different, the light path is less likely to be obstructed by the condensate. Also, the airflow is 2nd direction 32 After entering the atomizing chamber 1121 from the light-transmitting hole 1123 along the way, it forms an aerosol accompanied by hot atomized vapor, 1st direction 31 It enters the exhaust passage 1112 along this line. This makes it less likely for atomized aerosol particles to block the path of light. Also, normally, Condensate teeth Electron atomization assembly Because it adheres to the inner wall, the light rays can avoid the condensate through the translucent pores 1123.
[0075] The foregoing description represents only preferred embodiments of the present invention and does not limit it. Various modifications, combinations, and variations of the present invention are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., implemented within the spirit and principles of the present invention are all included within the scope of the claims.
