Description

TECHNICAL FIELD

[0001] The present invention relates to the field of electronic atomization, and more particularly to an optically heating electronic atomization assembly, a light source assembly, and an electronic atomization device.THE RELATED ART

[0002] Traditional electronic atomization devices primarily rely on the atomization core for performing heating and atomization. The atomization core commonly comprises a liquid guide member for conducting liquid and a heating piece in contact with the liquid guide member. The heating piece is electrically connected to a power supply and uses electricity as energy. The liquid in the liquid guide member is heated to the boiling point and evaporated into atomized vapor by controlling the heating piece to generate heat. The atomization core is currently widely used in the field of electronic cigarettes, and, at present, what is mostly adopted is using the heating effect of the electrical resistance of the heating piece to convert electrical energy into thermal energy to heat the atomizable liquid for evaporation into vapor.

[0003] There are some disadvantages of resistive heating, such as the problem of core sticking caused by poor contact between the heating body and the liquid guide member. The electronic atomization device used in electronic cigarettes often includes an atomization assembly and a power supply assembly combined with each other. The atomization core is usually arranged in the atomization assembly, and combination of the atomization assembly with the power supply assembly is to achieve a conductive connection and supply electrical power to the heating piece. If the conductive connection is poor, malfunction may result. Further, the resistive heating piece is mostly made of materials of metals or alloys, and electronic cigarettes are consumables and are used in large quantities. After use, these metals and alloys are often discarded together with the atomization assembly, causing waste and environmental pollution.

[0004] In addition, some electronic atomization devices use light to irradiate the liquid guide member to heat the atomizable liquid, but there are also some problems:

[0005] The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing atomized vapor of a certain temperature with air. A major portion of the atomized vapor passes through an air outlet channel to flow out of the electronic atomization device, while a minor portion of the atomized vapor becomes condensed when encountering a wall surface having a lower temperature in the interior of an electronic atomization assembly and gathers into condensation droplets. Since the electronic atomization device is usually used with the air outlet channel in a longitudinal state, and a light-emitting unit is also located at one side of the liquid guide member in the longitudinal direction, it can be easy for the condensed liquid or the liquid particles splashed during atomization to block the light path, affecting the atomization effect. The condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member to change, resulting in uneven heating.

[0006] Therefore, how to develop a new way of heating to overcome the above defects has become an urgent problem to be solved.SUMMARY OF THE INVENTION

[0029] Referring to FIGS. 1-3, in an optically heating electronic atomization assembly 1 according to one embodiment of the present invention, the electronic atomization assembly 1 comprises a first base 11 and a liquid guide member 12 arranged on the first base 11 for storing and conducting liquid. The first base 11 is provided with an atomization cavity 1121, an air outlet channel 1112, a light-transmitting hole 1123, and an air passage hole 1124. The air outlet channel 1112 is arranged along a first direction 31 and has one end in communication with the atomization cavity 1121 and an opposite end in communication with the outside of the electronic atomization assembly 1. The light-transmitting hole 1123 is opened along a second direction 32 and in communication with the outside of the electronic atomization assembly 1 and the atomization cavity 1121. The liquid guide member 12 comprises an atomization surface 121. The atomization surface 121 is exposed in the atomization cavity 1121 and is arranged at a position corresponding to the light-transmitting hole 1123 along the second direction 32, and the air passage hole 1124 is in communication with the atomization cavity 1121, so that light outside the electronic atomization assembly 1 passes through the light-transmitting hole 1123 along the second direction 32 to irradiate and heat the atomization surface 121 of the liquid guide member 12 to generate atomized vapor, and a gas flow passes, in sequence, through the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112 to carry the atomized vapor along the first direction 31 into the air outlet channel 1112. The first direction 31 intersects with the second direction 32, and the two are not parallel to each other.

[0030] The electronic atomization assembly 1 generates heat by light. Specifically, the liquid guide member 12 conducts and stores the atomizable liquid, and light outside the electronic atomization assembly 1 (such as light emitting from a light-emitting unit 22 of a light source assembly 2) irradiates the liquid guide member 12 along the second direction 32 through the light-transmitting hole 1123 to generate heat and heats the atomizable liquid on the liquid guide member 12 to the boiling point and to evaporate to produce atomized vapor. Compared with the traditional electronic atomization assembly 1 discussed in THE RELATED ART, the atomization assembly of the present invention has the following beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating piece and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating body and the liquid guide member 12. (5) The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing atomized vapor of a certain temperature and air. The electronic atomization assembly 1 of the present invention is made by taking into account that the atomized vapor, when encountering a wall surface having a lower temperature in the interior of the electronic atomization assembly 1, induces a phenomenon of condensation and gathers into condensation droplets. Since the electronic atomization assembly 1, after being combined with the light source assembly 2, is usually used with the air outlet channel 1112 set in a longitudinal state, that is, the first direction 31 is longitudinal, if the direction of opening of the air passage hole 1124 is also along the first direction 31, then the direction of light irradiation is usually also along the first direction 31, so that the light path can be easily blocked by the condensed liquid or the liquid particles splashed during atomization, affecting the atomization effect. The condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member 12 to change, resulting in problems of uneven heating. Therefore, in the electronic atomization assembly 1 of the present invention, the air outlet channel 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32, making the directions of the light path and the air outlet channel 1112 are different, so that the light path is not easily obstructed by the condensed liquid; in addition, the gas flow, after passing through the light-transmitting hole 1123 along the first direction 31 to enter the atomization cavity 1121, carries aerosol formed by the hot atomized vapor to enter the air outlet channel 1112 along the second direction 32, so that the particles of the atomized aerosol do not easily block the light path; further, the atomizable liquid usually adheres to the internal wall of electronic atomization assembly, and the light-transmitting hole 1123 allows the light to bypass the condensed liquid.

[0031] In the above, the liquid guide member 12 is generally made of porous materials or fiber materials, and is composed of fiber filaments such as non-woven fabrics, linen fiber cloth, and aramid cloth, and can also be a porous material of a solid form, such as porous ceramics, porous glass, and porous metal (since it does not need to be used in combination with a conductive heating piece and does not require power supply, metal can also be used), or a combination of materials thereof.

[0032] The air passage hole 1124 is opened along the second direction 32, and is on the same side of the first base 11 as the air passage hole 1124. One end of the air outlet channel 1112 is in communication with the atomization cavity 1121, and the opposite end is in communication with the outside of the electronic atomization assembly 1, so that a gas flow first passes through the air passage hole 1124 along the second direction 32 to enter the atomization cavity 1121, and then enters the air outlet channel 1112 along the first direction 31. Being on the same side of the first base 11 as the air passage hole 1124 facilitates the design of the light path and gas path of the electronic atomization assembly 1 and the light source assembly 2 described below.

[0033] The air passage hole 1124 is the light-transmitting hole 1123, so that the air passage hole 1124 is also the path of light, and in this way, there is no wall existing on the light path, and no condensed liquid will attach on the wall to affect the propagation of light; or alternatively, the air passage hole 1124 and the light-transmitting hole 1123 are separate holes, and gas flow and light pass through different holes. The light-transmitting hole 1123 and the atomization surface 121of the liquid guide body are respectively arranged on opposite sides of the atomization cavity 1121.

[0034] The first base 11 comprises a first main body portion 111 and a first combination portion 112 arranged on the first main body portion 111 and extending outwardly for combination with an external assembly (such as the light source assembly 2). The first base 11 is provided with a first combination vacancy 110 at a position corresponding to the light-transmitting hole 1123 for disposition of the light-emitting unit 22 of the light source assembly 2. The first combination vacancy 110 is located outside the atomization cavity 1121 in the second direction 32. The atomization cavity 1121 and the liquid guide member 12 are arranged in the first combination portion 112. The light-transmitting hole 1123 is formed in a side wall of the first combination portion 112 facing the first combination vacancy 110. The air outlet channel 1112 is arranged in the first main body portion 111.

[0035] 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. A 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 with the air passage hole 1124 formed therein jointly define the first combination vacancy 110.

[0036] Preferably, the first combination portion 112 protrudes outward from the first main body portion 111 along the first direction 31 to be pluggable into and connectable with the external assembly.

[0037] The first base 11 is provided, on the outside thereof, with a first foolproof step 114 inclined with respect to the first direction 31 for foolproofness during combination of the electronic atomization assembly 1 with the external assembly, such as the light source assembly 2. For example, foolproofness is achieved with the first foolproof step 114 when the electronic atomization assembly 1 is plugged to and connected with the light source assembly 2.

[0038] The first main body portion 111 is provided with a liquid storage cavity 1111 for storing atomizable liquid. The first combination portion 112 comprises a separation portion 1120 arranged therein, and the separation portion 1120 divides an internal space of the first combination portion 112 into the atomization cavity 1121 and a liquid entry cavity 1122 for storing the atomizable liquid and communicating with the liquid storage cavity 1111. In other words, the atomization cavity 1121 is provided on the first combination portion 112. The separation portion 1120 is provided with a mounting aperture 11200 in communication with the atomization cavity 1121 and the liquid entry cavity 1122. The liquid guide member 12 is arranged in the first combination portion 112 and mounted on the mounting aperture 11200. The liquid guide member 12 comprises a liquid entry surface 122 exposed in the liquid entry cavity 1122 for allowing the atomizable liquid to enter a liquid guide body. The atomization cavity 1121 and the liquid storage cavity 1111 are respectively provided on two sides of the separation portion 1120 in the first direction 31, so that the atomizable liquid in the liquid storage cavity 1111, after entering the liquid entry cavity 1122, passes through the liquid entry surface 122 to enter the liquid guide member 12.

[0039] The first main body portion 111 is provided with the liquid storage cavity 1111 in communication with the liquid entry cavity 1122. The electronic atomization assembly 1 is a consumable product, which is used to store the atomizable liquid, and to form a channel for atomized vapor and accommodate the liquid guide member 12.

[0040] The first base 11 comprises a liquid-guide sealing member 13. The liquid-guide sealing member 13 is arranged between the liquid guide member 12 and the mounting aperture 11200 for sealing between the atomization cavity 1121 and the liquid entry cavity 1122, so that the atomizable liquid in the liquid entry cavity 1122 does not enter the atomization cavity 1121.

[0041] Referring to FIGS. 4-8, an optically heating light source assembly 2 according to one embodiment of the present invention comprises a second base 21 and a light-emitting unit 22 arranged on the second base 21. The second base 21 comprises a second main body portion 211 and a second combination portion 212 arranged on one side of the second main body portion 211 in the first direction 31. A second combination vacancy 210 is provided on one side of the second combination portion 212 in the second direction 32 for disposition of an external assembly. The light-emitting unit 22 is arranged on the second combination portion 212, and the light-emitting unit 22 irradiates light along the second direction 32 toward the second combination vacancy 210. The first direction 31 intersects with the second direction 32, and the two are not parallel to each other.

[0042] The light source assembly 2 according to the present invention is combinable with the above-described electronic atomization assembly 1 to provide irradiation of light to the electronic atomization assembly 1 so as to utilize the light for heating to atomize. Specifically, when the light source assembly 2 is combined with the electronic atomization assembly 1, the portion of the electronic atomization assembly 1 that is provided with the light-transmitting hole 1123 is set in the second combination vacancy 210, and light from the light-emitting unit 22 of power supply device passes through the light-transmitting hole 1123 along the second direction 32 to irradiate the atomization surface 121 of the liquid guide member 12, causing the atomizable liquid to heat up and atomize.

[0043] The second base 21 comprises a casing 213. The size of the second combination portion 212 is smaller than the size of the second main body portion 211 in the second direction 32. The second main body portion 211 and the second combination portion 212 are arranged in the casing 213. The second main body portion 211, the second combination portion 212, and the casing 213 define the second combination vacancy 210. The second combination vacancy 210 is open to one side in the first direction 31 to allow the first combination portion of the electronic atomization assembly 1 to get into the second combination vacancy 210, while the second combination portion 212 gets into the first combination vacancy 110, so as to realize the combination of the electronic 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.

[0044] The electronic atomization assembly 1 is a consumable product, which is used to store the atomizable liquid, and to form a channel for atomized vapor and accommodate the liquid guide member 12. The light source assembly 2 functions to convert electrical energy to optical energy, and then convert the optical energy into thermal energy so as to use the thermal energy to heat the atomizable liquid of the atomization assembly.

[0045] The light source assembly 2 comprises a heat dissipating member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is provided therein with an air inlet channel 214 communicating with the outside. The heat dissipating member 23 and the light-emitting unit 22 are connected in a heat conducting manner (such as the two being connected through direct contact, or the two being connected via some heat-conducting materials therebetween). The heat dissipating member 23 is provided on the second combination portion 212, and the heat dissipating member 23 is provided with a plurality of heat dissipating grooves 231. The heat dissipating grooves 231 communicate with the air inlet channel 214 and the outside of the light source assembly 2. The heat dissipating member 23 is primarily for dissipating heat from the light-emitting unit 22 to prevent damage to the light-emitting unit 22 due to excessive temperatures during use, and is generally made of a metallic material with high thermal conductivity, such as aluminum, aluminum alloy, or copper, and a relatively large area thereof is in contact with the light-emitting unit 22 and is provided with a plurality of heat dissipating grooves 231 to allow gas to pass therethrough to take away heat. Specifically, on the one hand, the heat dissipating grooves 231 increases the area of contact between the heat dissipating member 23 and air to improve the heat dissipation effect, and on the other hand, in the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the external air flows sequentially through the air inlet channel 214, the heat dissipating grooves 231, the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112. First, the gas flow takes away heat from the heat dissipating member 23 to achieve heat dissipation for heat from the light-emitting unit 22, and then, the gas flow enters the atomization cavity 1121 to carry the atomized vapor into the air outlet channel 1112. Preferably, the heat dissipating member 23 is arranged on one side of the light-emitting unit 22 that faces away from the light-emitting side in the second direction 32. The heat dissipating grooves 231 are formed in the first direction 31.

[0046] The second combination vacancy 210 is an insertion hole open to one side in the first direction 31 for insertion of the first combination portion 112 of the electronic atomization assembly 1 therein. The light-emitting unit 22 and / or the heat dissipating member 23 are arranged on one side of the second combination vacancy 210 in the second direction 32.

[0047] The second base 21 is provided, on the outside thereof, with a second foolproof step 215 inclined with respect to the first direction 31 for foolproofness during combination of the light source assembly 2 with an external assembly (such as the electronic atomization assembly 1). For example, foolproofness is achieved with the second foolproof step 215 when the electronic atomization assembly 1 is plugged to and connected with the light source assembly 2.

[0048] The light source assembly 2 further comprises a battery 24 arranged on the second base 21 to supply electrical power to the light-emitting unit 22.

[0049] Referring to FIGS. 9-15, an optically heating electronic atomization device according to one embodiment of the present invention comprises the above-described light source assembly 2 and the above-described electronic atomization assembly 1 detachably combinable with the light source assembly 2. The light source assembly 2 comprises the second base 21 and the light-emitting unit 22 arranged on the second base 21. In the state that the light source assembly 2 and the electronic atomization 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 of the light-emitting unit 22 is irradiated along the second direction 32 through the light-transmitting hole 1123 and heats the atomization 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 atomization surface 121 of the liquid guide member 12 are all in the second direction 32 and in a straight line. This ensures that light can be concentrated on the liquid guide member 12, and also, there is no obstruction on the path of the light, which can avoid that the light cannot be concentrated on liquid conducting cotton to induce heat due to blockage of light. Also, this arrangement has the advantage that the absence of obstructions can prevent condensed liquid from accumulating on the wall. Condensed liquid on the path of light will refract the light and causes the light energy to disperse.

[0050] The electronic atomization device generates heat by light. Specifically, the liquid guide member 12 conducts and stores the atomizable liquid, and in the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, light from the light-emitting unit 22 of the light source assembly 2 irradiates the liquid guide member 12 along the second direction 32 through the light-transmitting hole 1123 to generate heat and heats the atomizable liquid on the liquid guide member 12 to the boiling point and evaporating to produce atomized vapor. Compared with the traditional electronic atomization device discussed in THE RELATED ART, the atomization device of the present invention has the following beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating body and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating piece and the liquid guide member 12.

[0051] The first base 11 comprises the first main body portion 111 and the first combination portion 112 arranged the first main body portion 111 and extending outwardly for combination with an external assembly (such as the light source assembly 2). The first base 11 is provided with the first combination vacancy 110 at a position corresponding to the light-transmitting hole 1123 for disposition of the light-emitting unit 22 of the light source assembly 2. The first combination vacancy 110 is located outside the atomization cavity 1121 in the second direction 32. The atomization cavity 1121 and the liquid guide member 12 are arranged in the first combination portion 112. The light-transmitting hole 1123 is formed in a side wall of the first combination portion 112 facing the first combination vacancy 110. The air outlet channel 1112 is arranged in the first main body portion 111. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the first combination portion 112 is set in the second combination vacancy 210, and the second combination portion 212 is set in the first combination vacancy 110.

[0052] The first base 11 is provided, on the outside thereof, with the first foolproof step 114 inclined with respect to the first direction 31, and the second base 21 is provided, on the outside thereof, with the second foolproof step 215 inclined with respect to the first direction 31 and matching the first foolproof step 114. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the first foolproof step 114 and the second foolproof step 215 abut against each other.

[0053] The light source assembly 2 comprises the heat dissipating member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is provided therein with the air inlet channel 214 communicating with the outside. The heat dissipating member 23 and the light-emitting unit 22 are connected in a heat conducting manner (such as the two being connected through direct contact, or the two being connected via some heat-conducting materials therebetween). The heat dissipating member 23 is provided on the second combination portion 212, and the heat dissipating member 23 is provided with the plurality of heat dissipating grooves 231. The heat dissipating grooves 231 communicate with the air inlet channel 214 and the outside of the light source assembly 2. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the air inlet channel 214, the heat dissipating grooves 231, the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112 are in communication with each other in order to allow a gas flow to take away heat from the heat dissipating member 23 to realize heat dissipation for the light-emitting unit 22, and the gas flow enters the atomization cavity 1121 to carry atomized vapor into the air outlet channel 1112.

[0054] For the electronic atomization assembly 1 and the light source assembly 2, or the electronic atomization device described above, reference may be made to FIG. 11, wherein the first direction 31 is inclined relative to the second direction 32, or reference may be made to FIG. 10, where the first direction 31 is perpendicular to the second direction 32.

[0055] The light-emitting unit 22 refers to an element that can generate light after being supplied with electrical power. The light-emitting unit 22 of the electronic atomization device according to the present invention may comprise a light-emitting body 221 for emitting light and a light condensing lens 222 connected to the light-emitting body 221 for concentrating light onto the atomization surface 121 of the liquid guide member 12. Heat is generated by concentrating the light from the light-emitting unit 22. Specifically, a high-power LED light source, an incandescent light source, a halogen light source, an infrared heating lamp light source, or a single-mode laser source, a multi-mode laser source, a semiconductor laser source, and a laser, which is integrated with the light condensing lens 222, can be used, and among them, a light-emitting unit 22 that emits infrared light is preferably selected. Specifically, a concave-convex mirror or a reflective material is provided in the light-emitting unit 22 to make the light emitting from the light-emitting body 221 concentrated in one direction or one spot.

[0056] In the electronic atomization device according to the present invention, the light of the light-emitting unit 22 converges onto the liquid guide member 12 to form a light spot, which heats the atomizable liquid on the liquid guide member 12. The size of the light spot is generally 2*2mm, or φ2mm in diameter. No limitation is imposed herein. If the power is large and the atomization amount is large, the power of the light emitting element and the size of the light spot can be appropriately increased.

[0057] The number of the light-emitting unit 22 can be multiple, such as multiple lasers. The light emitted by the light-emitting unit 22 has a single wavelength and thus highly concentrated energy and a high degree of the heat concentration.

[0058] The electronic atomization assembly 1 and the electronic atomization device according to the present invention use light to heat and atomize the atomizable liquid. Light is also a type of energy. 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 light wave ovens for cooking, using high-power lasers to cut metals, and using lasers for welding, all of which use light to generate heat. With the development of technology, light-generated heat is also widely used in some special industries, and the existing electronic atomization devices also need to convert electrical energy into thermal energy for heating and atomizing liquid, and therefore, the feasibility of the present invention for applying this technology to the electronic atomization assembly 1 and the electronic atomization device is very high. Moreover, with the development of technology, the light-emitting and focusing module can be made into a very small size. For example, the core light-emitting unit 22 can be made into 4*4*2mm, and the temperature required for the atomization of the atomizable liquid is only more than 200 degrees. The light-emitting unit 22 of 3-8W can meet this temperature after focusing of light. Therefore, the feasibility is very high.

[0059] When the electronic atomization device of the present invention is in use, airflow enters the light source assembly 2 from an opening of the air inlet channel 214 in the bottom of the light source assembly 2, passes through the air inlet channel 214, and then passes through the heat dissipating grooves 231 of the heat dissipating member 23 to then flow in through the air passage hole 1124 of the electronic atomization assembly 1 to enter the atomization cavity 1121 and pass over the atomization surface 121 of the liquid guide member 12, and the air flow carries atomized vapor and then enters the air outlet channel 1112 to finally flow out of the electronic atomization assembly 1.

[0060] In summary, the electronic atomization assembly 1, the light source assembly 2, and the electronic atomization device according to the present invention have at least beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating piece and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating body and the liquid guide member 12. (5) The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing vapor of a certain temperature and air. The electronic atomization assembly 1 of the present invention is made by taking into account that the vapor, when encountering a wall surface having a lower temperature in the interior of the electronic atomization assembly 1, induces a phenomenon of condensation and gathers into condensation droplets. If light hits the condensed liquid, the condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member 12 to change, resulting in problems of uneven heating. Since the electronic atomization assembly 1, after being combined with the light source assembly 2, is usually used with the air outlet channel 1112 set in a longitudinal state (namely the first direction 31 being longitudinal), if the direction of opening of the air passage hole 1124 is also along the first direction 31, then the direction of light irradiation is usually also along the first direction 31, so that the light path can be easily blocked by the condensed liquid or the liquid particles splashed during atomization, affecting the atomization effect. Therefore, in the electronic atomization assembly 1 of the present invention, the air outlet channel 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32, making the directions of the light path and the air outlet channel 1112 different, so that the light path is not easily obstructed by the condensed liquid; in addition, the gas flow, after passing through the light-transmitting hole 1123 along the first direction 31 to enter the atomization cavity 1121, carries aerosol formed by the hot atomized vapor to enter the air outlet channel 1112 along the second direction 32, so that the particles of the atomized aerosol do not easily block the light path; further, the atomizable liquid usually adheres to the internal wall of electronic atomization, and the light-transmitting hole 1123 allows the light to bypass the condensed liquid.

[0061] The above describes only preferred embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may be modified, combined and varied in various ways. Any modification, equivalent substitution, and improvement made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.

TECHNICAL FIELD

[0001] The present invention relates to the field of electronic atomization, and more particularly to an optically heating electronic atomization assembly, a light source assembly, and an electronic atomization device.THE RELATED ART

[0002] Traditional electronic atomization devices primarily rely on the atomization core for performing heating and atomization. The atomization core commonly comprises a liquid guide member for conducting liquid and a heating piece in contact with the liquid guide member. The heating piece is electrically connected to a power supply and uses electricity as energy. The liquid in the liquid guide member is heated to the boiling point and evaporated into atomized vapor by controlling the heating piece to generate heat. The atomization core is currently widely used in the field of electronic cigarettes, and, at present, what is mostly adopted is using the heating effect of the electrical resistance of the heating piece to convert electrical energy into thermal energy to heat the atomizable liquid for evaporation into vapor.

[0003] There are some disadvantages of resistive heating, such as the problem of core sticking caused by poor contact between the heating body and the liquid guide member. The electronic atomization device used in electronic cigarettes often includes an atomization assembly and a power supply assembly combined with each other. The atomization core is usually arranged in the atomization assembly, and combination of the atomization assembly with the power supply assembly is to achieve a conductive connection and supply electrical power to the heating piece. If the conductive connection is poor, malfunction may result. Further, the resistive heating piece is mostly made of materials of metals or alloys, and electronic cigarettes are consumables and are used in large quantities. After use, these metals and alloys are often discarded together with the atomization assembly, causing waste and environmental pollution.

[0004] In addition, some electronic atomization devices use light to irradiate the liquid guide member to heat the atomizable liquid, but there are also some problems:

[0005] The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing atomized vapor of a certain temperature with air. A major portion of the atomized vapor passes through an air outlet channel to flow out of the electronic atomization device, while a minor portion of the atomized vapor becomes condensed when encountering a wall surface having a lower temperature in the interior of an electronic atomization assembly and gathers into condensation droplets. Since the electronic atomization device is usually used with the air outlet channel in a longitudinal state, and a light-emitting unit is also located at one side of the liquid guide member in the longitudinal direction, it can be easy for the condensed liquid or the liquid particles splashed during atomization to block the light path, affecting the atomization effect. The condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member to change, resulting in uneven heating.

[0006] Therefore, how to develop a new way of heating to overcome the above defects has become an urgent problem to be solved.SUMMARY OF THE INVENTION

[0029] Referring to FIGS. 1-3, in an optically heating electronic atomization assembly 1 according to one embodiment of the present invention, the electronic atomization assembly 1 comprises a first base 11 and a liquid guide member 12 arranged on the first base 11 for storing and conducting liquid. The first base 11 is provided with an atomization cavity 1121, an air outlet channel 1112, a light-transmitting hole 1123, and an air passage hole 1124. The air outlet channel 1112 is arranged along a first direction 31 and has one end in communication with the atomization cavity 1121 and an opposite end in communication with the outside of the electronic atomization assembly 1. The light-transmitting hole 1123 is opened along a second direction 32 and in communication with the outside of the electronic atomization assembly 1 and the atomization cavity 1121. The liquid guide member 12 comprises an atomization surface 121. The atomization surface 121 is exposed in the atomization cavity 1121 and is arranged at a position corresponding to the light-transmitting hole 1123 along the second direction 32, and the air passage hole 1124 is in communication with the atomization cavity 1121, so that light outside the electronic atomization assembly 1 passes through the light-transmitting hole 1123 along the second direction 32 to irradiate and heat the atomization surface 121 of the liquid guide member 12 to generate atomized vapor, and a gas flow passes, in sequence, through the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112 to carry the atomized vapor along the first direction 31 into the air outlet channel 1112. The first direction 31 intersects with the second direction 32, and the two are not parallel to each other.

[0030] The electronic atomization assembly 1 generates heat by light. Specifically, the liquid guide member 12 conducts and stores the atomizable liquid, and light outside the electronic atomization assembly 1 (such as light emitting from a light-emitting unit 22 of a light source assembly 2) irradiates the liquid guide member 12 along the second direction 32 through the light-transmitting hole 1123 to generate heat and heats the atomizable liquid on the liquid guide member 12 to the boiling point and to evaporate to produce atomized vapor. Compared with the traditional electronic atomization assembly 1 discussed in THE RELATED ART, the atomization assembly of the present invention has the following beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating piece and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating body and the liquid guide member 12. (5) The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing atomized vapor of a certain temperature and air. The electronic atomization assembly 1 of the present invention is made by taking into account that the atomized vapor, when encountering a wall surface having a lower temperature in the interior of the electronic atomization assembly 1, induces a phenomenon of condensation and gathers into condensation droplets. Since the electronic atomization assembly 1, after being combined with the light source assembly 2, is usually used with the air outlet channel 1112 set in a longitudinal state, that is, the first direction 31 is longitudinal, if the direction of opening of the air passage hole 1124 is also along the first direction 31, then the direction of light irradiation is usually also along the first direction 31, so that the light path can be easily blocked by the condensed liquid or the liquid particles splashed during atomization, affecting the atomization effect. The condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member 12 to change, resulting in problems of uneven heating. Therefore, in the electronic atomization assembly 1 of the present invention, the air outlet channel 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32, making the directions of the light path and the air outlet channel 1112 are different, so that the light path is not easily obstructed by the condensed liquid; in addition, the gas flow, after passing through the light-transmitting hole 1123 along the first direction 31 to enter the atomization cavity 1121, carries aerosol formed by the hot atomized vapor to enter the air outlet channel 1112 along the second direction 32, so that the particles of the atomized aerosol do not easily block the light path; further, the atomizable liquid usually adheres to the internal wall of electronic atomization assembly, and the light-transmitting hole 1123 allows the light to bypass the condensed liquid.

[0031] In the above, the liquid guide member 12 is generally made of porous materials or fiber materials, and is composed of fiber filaments such as non-woven fabrics, linen fiber cloth, and aramid cloth, and can also be a porous material of a solid form, such as porous ceramics, porous glass, and porous metal (since it does not need to be used in combination with a conductive heating piece and does not require power supply, metal can also be used), or a combination of materials thereof.

[0032] The air passage hole 1124 is opened along the second direction 32, and is on the same side of the first base 11 as the air passage hole 1124. One end of the air outlet channel 1112 is in communication with the atomization cavity 1121, and the opposite end is in communication with the outside of the electronic atomization assembly 1, so that a gas flow first passes through the air passage hole 1124 along the second direction 32 to enter the atomization cavity 1121, and then enters the air outlet channel 1112 along the first direction 31. Being on the same side of the first base 11 as the air passage hole 1124 facilitates the design of the light path and gas path of the electronic atomization assembly 1 and the light source assembly 2 described below.

[0033] The air passage hole 1124 is the light-transmitting hole 1123, so that the air passage hole 1124 is also the path of light, and in this way, there is no wall existing on the light path, and no condensed liquid will attach on the wall to affect the propagation of light; or alternatively, the air passage hole 1124 and the light-transmitting hole 1123 are separate holes, and gas flow and light pass through different holes. The light-transmitting hole 1123 and the atomization surface 121of the liquid guide body are respectively arranged on opposite sides of the atomization cavity 1121.

[0034] The first base 11 comprises a first main body portion 111 and a first combination portion 112 arranged on the first main body portion 111 and extending outwardly for combination with an external assembly (such as the light source assembly 2). The first base 11 is provided with a first combination vacancy 110 at a position corresponding to the light-transmitting hole 1123 for disposition of the light-emitting unit 22 of the light source assembly 2. The first combination vacancy 110 is located outside the atomization cavity 1121 in the second direction 32. The atomization cavity 1121 and the liquid guide member 12 are arranged in the first combination portion 112. The light-transmitting hole 1123 is formed in a side wall of the first combination portion 112 facing the first combination vacancy 110. The air outlet channel 1112 is arranged in the first main body portion 111.

[0035] 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. A 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 with the air passage hole 1124 formed therein jointly define the first combination vacancy 110.

[0036] Preferably, the first combination portion 112 protrudes outward from the first main body portion 111 along the first direction 31 to be pluggable into and connectable with the external assembly.

[0037] The first base 11 is provided, on the outside thereof, with a first foolproof step 114 inclined with respect to the first direction 31 for foolproofness during combination of the electronic atomization assembly 1 with the external assembly, such as the light source assembly 2. For example, foolproofness is achieved with the first foolproof step 114 when the electronic atomization assembly 1 is plugged to and connected with the light source assembly 2.

[0038] The first main body portion 111 is provided with a liquid storage cavity 1111 for storing atomizable liquid. The first combination portion 112 comprises a separation portion 1120 arranged therein, and the separation portion 1120 divides an internal space of the first combination portion 112 into the atomization cavity 1121 and a liquid entry cavity 1122 for storing the atomizable liquid and communicating with the liquid storage cavity 1111. In other words, the atomization cavity 1121 is provided on the first combination portion 112. The separation portion 1120 is provided with a mounting aperture 11200 in communication with the atomization cavity 1121 and the liquid entry cavity 1122. The liquid guide member 12 is arranged in the first combination portion 112 and mounted on the mounting aperture 11200. The liquid guide member 12 comprises a liquid entry surface 122 exposed in the liquid entry cavity 1122 for allowing the atomizable liquid to enter a liquid guide body. The atomization cavity 1121 and the liquid storage cavity 1111 are respectively provided on two sides of the separation portion 1120 in the first direction 31, so that the atomizable liquid in the liquid storage cavity 1111, after entering the liquid entry cavity 1122, passes through the liquid entry surface 122 to enter the liquid guide member 12.

[0039] The first main body portion 111 is provided with the liquid storage cavity 1111 in communication with the liquid entry cavity 1122. The electronic atomization assembly 1 is a consumable product, which is used to store the atomizable liquid, and to form a channel for atomized vapor and accommodate the liquid guide member 12.

[0040] The first base 11 comprises a liquid-guide sealing member 13. The liquid-guide sealing member 13 is arranged between the liquid guide member 12 and the mounting aperture 11200 for sealing between the atomization cavity 1121 and the liquid entry cavity 1122, so that the atomizable liquid in the liquid entry cavity 1122 does not enter the atomization cavity 1121.

[0041] Referring to FIGS. 4-8, an optically heating light source assembly 2 according to one embodiment of the present invention comprises a second base 21 and a light-emitting unit 22 arranged on the second base 21. The second base 21 comprises a second main body portion 211 and a second combination portion 212 arranged on one side of the second main body portion 211 in the first direction 31. A second combination vacancy 210 is provided on one side of the second combination portion 212 in the second direction 32 for disposition of an external assembly. The light-emitting unit 22 is arranged on the second combination portion 212, and the light-emitting unit 22 irradiates light along the second direction 32 toward the second combination vacancy 210. The first direction 31 intersects with the second direction 32, and the two are not parallel to each other.

[0042] The light source assembly 2 according to the present invention is combinable with the above-described electronic atomization assembly 1 to provide irradiation of light to the electronic atomization assembly 1 so as to utilize the light for heating to atomize. Specifically, when the light source assembly 2 is combined with the electronic atomization assembly 1, the portion of the electronic atomization assembly 1 that is provided with the light-transmitting hole 1123 is set in the second combination vacancy 210, and light from the light-emitting unit 22 of power supply device passes through the light-transmitting hole 1123 along the second direction 32 to irradiate the atomization surface 121 of the liquid guide member 12, causing the atomizable liquid to heat up and atomize.

[0043] The second base 21 comprises a casing 213. The size of the second combination portion 212 is smaller than the size of the second main body portion 211 in the second direction 32. The second main body portion 211 and the second combination portion 212 are arranged in the casing 213. The second main body portion 211, the second combination portion 212, and the casing 213 define the second combination vacancy 210. The second combination vacancy 210 is open to one side in the first direction 31 to allow the first combination portion of the electronic atomization assembly 1 to get into the second combination vacancy 210, while the second combination portion 212 gets into the first combination vacancy 110, so as to realize the combination of the electronic 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.

[0044] The electronic atomization assembly 1 is a consumable product, which is used to store the atomizable liquid, and to form a channel for atomized vapor and accommodate the liquid guide member 12. The light source assembly 2 functions to convert electrical energy to optical energy, and then convert the optical energy into thermal energy so as to use the thermal energy to heat the atomizable liquid of the atomization assembly.

[0045] The light source assembly 2 comprises a heat dissipating member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is provided therein with an air inlet channel 214 communicating with the outside. The heat dissipating member 23 and the light-emitting unit 22 are connected in a heat conducting manner (such as the two being connected through direct contact, or the two being connected via some heat-conducting materials therebetween). The heat dissipating member 23 is provided on the second combination portion 212, and the heat dissipating member 23 is provided with a plurality of heat dissipating grooves 231. The heat dissipating grooves 231 communicate with the air inlet channel 214 and the outside of the light source assembly 2. The heat dissipating member 23 is primarily for dissipating heat from the light-emitting unit 22 to prevent damage to the light-emitting unit 22 due to excessive temperatures during use, and is generally made of a metallic material with high thermal conductivity, such as aluminum, aluminum alloy, or copper, and a relatively large area thereof is in contact with the light-emitting unit 22 and is provided with a plurality of heat dissipating grooves 231 to allow gas to pass therethrough to take away heat. Specifically, on the one hand, the heat dissipating grooves 231 increases the area of contact between the heat dissipating member 23 and air to improve the heat dissipation effect, and on the other hand, in the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the external air flows sequentially through the air inlet channel 214, the heat dissipating grooves 231, the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112. First, the gas flow takes away heat from the heat dissipating member 23 to achieve heat dissipation for heat from the light-emitting unit 22, and then, the gas flow enters the atomization cavity 1121 to carry the atomized vapor into the air outlet channel 1112. Preferably, the heat dissipating member 23 is arranged on one side of the light-emitting unit 22 that faces away from the light-emitting side in the second direction 32. The heat dissipating grooves 231 are formed in the first direction 31.

[0046] The second combination vacancy 210 is an insertion hole open to one side in the first direction 31 for insertion of the first combination portion 112 of the electronic atomization assembly 1 therein. The light-emitting unit 22 and / or the heat dissipating member 23 are arranged on one side of the second combination vacancy 210 in the second direction 32.

[0047] The second base 21 is provided, on the outside thereof, with a second foolproof step 215 inclined with respect to the first direction 31 for foolproofness during combination of the light source assembly 2 with an external assembly (such as the electronic atomization assembly 1). For example, foolproofness is achieved with the second foolproof step 215 when the electronic atomization assembly 1 is plugged to and connected with the light source assembly 2.

[0048] The light source assembly 2 further comprises a battery 24 arranged on the second base 21 to supply electrical power to the light-emitting unit 22.

[0049] Referring to FIGS. 9-15, an optically heating electronic atomization device according to one embodiment of the present invention comprises the above-described light source assembly 2 and the above-described electronic atomization assembly 1 detachably combinable with the light source assembly 2. The light source assembly 2 comprises the second base 21 and the light-emitting unit 22 arranged on the second base 21. In the state that the light source assembly 2 and the electronic atomization 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 of the light-emitting unit 22 is irradiated along the second direction 32 through the light-transmitting hole 1123 and heats the atomization 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 atomization surface 121 of the liquid guide member 12 are all in the second direction 32 and in a straight line. This ensures that light can be concentrated on the liquid guide member 12, and also, there is no obstruction on the path of the light, which can avoid that the light cannot be concentrated on liquid conducting cotton to induce heat due to blockage of light. Also, this arrangement has the advantage that the absence of obstructions can prevent condensed liquid from accumulating on the wall. Condensed liquid on the path of light will refract the light and causes the light energy to disperse.

[0050] The electronic atomization device generates heat by light. Specifically, the liquid guide member 12 conducts and stores the atomizable liquid, and in the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, light from the light-emitting unit 22 of the light source assembly 2 irradiates the liquid guide member 12 along the second direction 32 through the light-transmitting hole 1123 to generate heat and heats the atomizable liquid on the liquid guide member 12 to the boiling point and evaporating to produce atomized vapor. Compared with the traditional electronic atomization device discussed in THE RELATED ART, the atomization device of the present invention has the following beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating body and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating piece and the liquid guide member 12.

[0051] The first base 11 comprises the first main body portion 111 and the first combination portion 112 arranged the first main body portion 111 and extending outwardly for combination with an external assembly (such as the light source assembly 2). The first base 11 is provided with the first combination vacancy 110 at a position corresponding to the light-transmitting hole 1123 for disposition of the light-emitting unit 22 of the light source assembly 2. The first combination vacancy 110 is located outside the atomization cavity 1121 in the second direction 32. The atomization cavity 1121 and the liquid guide member 12 are arranged in the first combination portion 112. The light-transmitting hole 1123 is formed in a side wall of the first combination portion 112 facing the first combination vacancy 110. The air outlet channel 1112 is arranged in the first main body portion 111. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the first combination portion 112 is set in the second combination vacancy 210, and the second combination portion 212 is set in the first combination vacancy 110.

[0052] The first base 11 is provided, on the outside thereof, with the first foolproof step 114 inclined with respect to the first direction 31, and the second base 21 is provided, on the outside thereof, with the second foolproof step 215 inclined with respect to the first direction 31 and matching the first foolproof step 114. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the first foolproof step 114 and the second foolproof step 215 abut against each other.

[0053] The light source assembly 2 comprises the heat dissipating member 23 for dissipating heat from the light-emitting unit 22. The light source assembly 2 is provided therein with the air inlet channel 214 communicating with the outside. The heat dissipating member 23 and the light-emitting unit 22 are connected in a heat conducting manner (such as the two being connected through direct contact, or the two being connected via some heat-conducting materials therebetween). The heat dissipating member 23 is provided on the second combination portion 212, and the heat dissipating member 23 is provided with the plurality of heat dissipating grooves 231. The heat dissipating grooves 231 communicate with the air inlet channel 214 and the outside of the light source assembly 2. In the state that the electronic atomization assembly 1 and the light source assembly 2 are combined, the air inlet channel 214, the heat dissipating grooves 231, the air passage hole 1124, the atomization cavity 1121, and the air outlet channel 1112 are in communication with each other in order to allow a gas flow to take away heat from the heat dissipating member 23 to realize heat dissipation for the light-emitting unit 22, and the gas flow enters the atomization cavity 1121 to carry atomized vapor into the air outlet channel 1112.

[0054] For the electronic atomization assembly 1 and the light source assembly 2, or the electronic atomization device described above, reference may be made to FIG. 11, wherein the first direction 31 is inclined relative to the second direction 32, or reference may be made to FIG. 10, where the first direction 31 is perpendicular to the second direction 32.

[0055] The light-emitting unit 22 refers to an element that can generate light after being supplied with electrical power. The light-emitting unit 22 of the electronic atomization device according to the present invention may comprise a light-emitting body 221 for emitting light and a light condensing lens 222 connected to the light-emitting body 221 for concentrating light onto the atomization surface 121 of the liquid guide member 12. Heat is generated by concentrating the light from the light-emitting unit 22. Specifically, a high-power LED light source, an incandescent light source, a halogen light source, an infrared heating lamp light source, or a single-mode laser source, a multi-mode laser source, a semiconductor laser source, and a laser, which is integrated with the light condensing lens 222, can be used, and among them, a light-emitting unit 22 that emits infrared light is preferably selected. Specifically, a concave-convex mirror or a reflective material is provided in the light-emitting unit 22 to make the light emitting from the light-emitting body 221 concentrated in one direction or one spot.

[0056] In the electronic atomization device according to the present invention, the light of the light-emitting unit 22 converges onto the liquid guide member 12 to form a light spot, which heats the atomizable liquid on the liquid guide member 12. The size of the light spot is generally 2*2mm, or φ2mm in diameter. No limitation is imposed herein. If the power is large and the atomization amount is large, the power of the light emitting element and the size of the light spot can be appropriately increased.

[0057] The number of the light-emitting unit 22 can be multiple, such as multiple lasers. The light emitted by the light-emitting unit 22 has a single wavelength and thus highly concentrated energy and a high degree of the heat concentration.

[0058] The electronic atomization assembly 1 and the electronic atomization device according to the present invention use light to heat and atomize the atomizable liquid. Light is also a type of energy. 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 light wave ovens for cooking, using high-power lasers to cut metals, and using lasers for welding, all of which use light to generate heat. With the development of technology, light-generated heat is also widely used in some special industries, and the existing electronic atomization devices also need to convert electrical energy into thermal energy for heating and atomizing liquid, and therefore, the feasibility of the present invention for applying this technology to the electronic atomization assembly 1 and the electronic atomization device is very high. Moreover, with the development of technology, the light-emitting and focusing module can be made into a very small size. For example, the core light-emitting unit 22 can be made into 4*4*2mm, and the temperature required for the atomization of the atomizable liquid is only more than 200 degrees. The light-emitting unit 22 of 3-8W can meet this temperature after focusing of light. Therefore, the feasibility is very high.

[0059] When the electronic atomization device of the present invention is in use, airflow enters the light source assembly 2 from an opening of the air inlet channel 214 in the bottom of the light source assembly 2, passes through the air inlet channel 214, and then passes through the heat dissipating grooves 231 of the heat dissipating member 23 to then flow in through the air passage hole 1124 of the electronic atomization assembly 1 to enter the atomization cavity 1121 and pass over the atomization surface 121 of the liquid guide member 12, and the air flow carries atomized vapor and then enters the air outlet channel 1112 to finally flow out of the electronic atomization assembly 1.

[0060] In summary, the electronic atomization assembly 1, the light source assembly 2, and the electronic atomization device according to the present invention have at least beneficial technical effects: (1) The atomizable liquid contacts fewer substances (contacting only the first base 11 and the liquid-conducting material, and not contacting the metal or alloy heating piece as in the traditional resistive heating way discussed in THE RELATED ART), avoiding contact with metal conductors, so as to be safer. (2) The electronic atomization assembly 1 does not include a resistive heating type heating piece, and the electronic atomization assembly 1 does not need to be electrically connected to the light source assembly 2 to supply power to the heating piece, so that there is no need to consider issues of conductive contact between the electronic atomization assembly 1 and the light source assembly 2, and the failure rate is lower. (3) The electronic atomization assembly 1 does not include a resistive heating type heating piece, so that the structure is simpler, the components are fewer, and the cost is lower (for the electronic atomization assembly 1 used in electronic cigarettes, the electronic atomization assembly 1 is a consumable part, and reducing the components of this part greatly reduces the cost of use). (4) The atomization effect is more stable and reliable, and there is no need for stable connection between a heating piece and the liquid guide member 12 for heating of the atomizable liquid on the liquid guide member 12 is made directly by irradiating light, so that there is no problem of core sticking caused by poor contact between a heating body and the liquid guide member 12. (5) The atomized vapor produced through atomization is also called an aerosol, which is formed by mixing vapor of a certain temperature and air. The electronic atomization assembly 1 of the present invention is made by taking into account that the vapor, when encountering a wall surface having a lower temperature in the interior of the electronic atomization assembly 1, induces a phenomenon of condensation and gathers into condensation droplets. If light hits the condensed liquid, the condensed liquid will cause refraction of light, blocking and dispersing the propagation of light, causing the size and shape of the light spot acting on the liquid guide member 12 to change, resulting in problems of uneven heating. Since the electronic atomization assembly 1, after being combined with the light source assembly 2, is usually used with the air outlet channel 1112 set in a longitudinal state (namely the first direction 31 being longitudinal), if the direction of opening of the air passage hole 1124 is also along the first direction 31, then the direction of light irradiation is usually also along the first direction 31, so that the light path can be easily blocked by the condensed liquid or the liquid particles splashed during atomization, affecting the atomization effect. Therefore, in the electronic atomization assembly 1 of the present invention, the air outlet channel 1112 is arranged along the first direction 31, and the light-transmitting hole 1123 is opened along the second direction 32, making the directions of the light path and the air outlet channel 1112 different, so that the light path is not easily obstructed by the condensed liquid; in addition, the gas flow, after passing through the light-transmitting hole 1123 along the first direction 31 to enter the atomization cavity 1121, carries aerosol formed by the hot atomized vapor to enter the air outlet channel 1112 along the second direction 32, so that the particles of the atomized aerosol do not easily block the light path; further, the atomizable liquid usually adheres to the internal wall of electronic atomization, and the light-transmitting hole 1123 allows the light to bypass the condensed liquid.

For those skilled in the art, the present invention may be modified, combined and varied in various ways. Any modification, equivalent substitution, and improvement made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
