[0041] Example:

[0042] See also Figure 1 and Figure 2 , an embodiment of the present invention provides an electronic atomization device, including a housing 100, an atomizer 200, a laser emitting assembly 300 and a control board 400. The atomizer 200 is connected to one end of the housing 100; wherein, the atomizer 200 and the housing 100 can be set in a detachable connection or a fixed connection. For example, when the atomizer 200 and the housing 100 are detachably connected, the connection mode between the atomizer 200 and the housing 100 can be a snap-fit ​​connection and a magnetic connection. The laser emitting assembly 300 is arranged in the housing 100, and the laser assembly is used to emit a laser to the atomizer 200; wherein, the light emitting direction of the laser emitting assembly 300 is toward the atomizer 200, and the atomizer 200 absorbs the laser energy and converts it into heat energy to heat the atomized medium to generate an aerosol; the control board 400 is arranged in the housing 100, and the control board 400 is electrically connected to the laser emitting assembly 300, and the control board 400 controls the laser power emitted by the laser emitting assembly 300.

[0043] See also Figure 2 , Figure 3 and Figure 4 The atomizer 200 includes a first cup body 210 and a light absorbing base 220. The two ends of the first cup body 210 are connected; the light absorbing base 220 is arranged on the first cup body 210, and the light absorbing base 220 and the first cup body 210 are enclosed to form a first accommodating cavity 212, and the first accommodating cavity 212 is used to store the atomized medium, and a portion of the light absorbing base 220 extends along the axial direction of the first cup body 210 to contact the inner circumferential wall of the first cup body 210; wherein the light absorbing base 220 is used to absorb laser energy and convert it into heat energy to heat the atomized medium to generate an aerosol.

[0044] The two ends of the first cup body 210 are connected, and the light absorbing base 220 and the first cup body 210 are enclosed to form a first accommodating chamber 212, and the first accommodating chamber 212 is used to store the atomized medium, and the atomized medium is placed on the light absorbing base 220. The light absorbing base 220 absorbs laser energy and converts it into heat energy to heat the atomized medium to generate an aerosol, and part of the light absorbing base 220 is in contact with the inner circumferential wall of the first cup body 210, so that the atomized medium attached to the side wall of the first cup body 210 can also be fully heated, so as to prevent the atomized medium from solidifying on the inner circumferential wall of the first cup body 210, so that the atomized medium in the first cup body 210 is fully atomized.

[0045] It should be noted that the atomizing medium is a paste, which evaporates when heated to generate an aerosol. The light absorbing base 220 is located at the bottom of the first cup body 210, and the light emitting direction of the laser emitting assembly 300 is toward the light absorbing base 220, so that the laser emitted by the laser emitting assembly 300 is convenient for irradiating the light absorbing base 220. The first cup body 210 is made of a high temperature resistant material, and the first cup body 210 can be a glass cup or a plastic cup.

[0046] In some embodiments, the light absorbing base 220 may have both light absorbing and liquid guiding functions. For example, the light absorbing base 220 may be a porous ceramic body. When the porous ceramic body heats the paste stored in the first accommodating cavity 212, part of the paste is heated and converted into atomized liquid. The part of the atomized liquid will be absorbed by the porous ceramic body, so that the porous ceramic body can heat the atomized liquid it holds and the paste stored in the first accommodating cavity 212 after absorbing the laser energy. At this time, the light absorbing base 220 is both a liquid guiding body and a heating body. Alternatively, the light absorbing base 220 only has a light absorbing function. For example, the light absorbing base 220 is made of light absorbing material only. At this time, the light absorbing base 220 is only a heating body.

[0047] See also Figure 2 , Figure 3 and Figure 4 The atomizer 200 further includes a second cup body 250, which is fixedly mounted on the outside of the first cup body 210 and is light-transmissive. The light-absorbing base 220 is disposed between the bottom end of the first cup body 210 and the bottom end of the second cup body 250, and the light-absorbing base 220 is clamped and fixed by the first cup body 210 and the second cup body 250, thereby achieving the fixation of the light-absorbing base 220. Moreover, the light-transmissive setting of the second cup body 250 ensures that the laser can be irradiated on the light-absorbing base 220 through the second cup body 250.

[0048] According to actual needs, the second cup body 250 is open at the top and closed at the bottom, and the bottom of the second cup body 250 is light-transmissive. The second cup body 250 is made of a material that is both thermally conductive and light-transmissive. For example, the second cup body 250 can be a glass cup or a plastic cup. The inner diameter of the second cup body 250 is the same as the outer diameter of the first cup body 210 to ensure that the second cup body 250 can be mounted and fixed on the outside of the first cup body 210.

[0049] It should be understood that, since the light absorbing base 220 is clamped and fixed by the first cup body 210 and the second cup body 250, the light absorbing base 220, the first cup body 210 and the second cup body 250 are detachably connected, which is convenient for installation and removal. In addition, when the light absorbing base 220 has both light absorbing function and liquid guiding function, for example, when the light absorbing base 220 is a porous ceramic body, since the light absorbing base 220 is arranged between the first cup body 210 and the second cup body 250, when the atomized liquid held by the light absorbing base 220 leaks, the second cup body 250 can store the leaked atomized liquid.

[0050] See also Figure 3 and Figure 4 , the light absorbing base 220 includes a light absorbing part 221 and a heat conducting part 222. The light absorbing part 221 is arranged at one end of the first cup body 210, and the light absorbing part 221 and the first cup body 210 are enclosed to form a first accommodating cavity 212, and the light absorbing part 221 is clamped and fixed by the first cup body 210 and the second cup body 250; wherein, the light absorbing part 221 is located at the bottom end of the first cup body 210, and the light absorbing part 221 can absorb laser energy and convert it into heat energy to heat the atomized medium to generate aerosol. The heat conducting part 222 is arranged on the plate surface of the light absorbing part 221, and the heat conducting part 222 extends along the axial direction of the first cup body 210 to contact the inner peripheral wall of the first cup body 210, and the heat on the light absorbing part 221 can be conducted to the heat conducting part 222, and the heat conducting part 222 heats the atomized medium attached to the inner peripheral wall of the first cup body 210.

[0051] According to actual needs, the light absorbing portion 221 can be a circular plate, and the diameter of the light absorbing portion 221 is larger than the inner diameter of the first cup body 210, so that the two sides of the light absorbing portion 221 can be respectively contacted with the first cup body 210 and the second cup body 250 to be clamped. The diameter of the light absorbing portion 221 is the same as the outer diameter of the first cup body 210, so as to ensure that the light absorbing base 220 can be clamped and fixed by the first cup body 210 and the second cup body 250.

[0052] It should be noted that the light absorbing portion 221 and the heat conducting portion 222 can be connected as one or separately. When the light absorbing portion 221 and the heat conducting portion 222 are connected as one, the light absorbing portion 221 and the heat conducting portion 222 are made of the same material, for example, the light absorbing portion 221 and the heat conducting portion 222 can be made of ceramic material. When the light absorbing portion 221 and the heat conducting portion 222 are separately provided, the light absorbing portion 221 and the heat conducting portion 222 can be made of different materials, for example, the light absorbing portion 221 is made of a light absorbing material with a higher light-to-heat conversion efficiency, and the heat conducting portion 222 is made of a heat conducting material with a higher thermal conductivity.

[0053] See also Figure 3 and Figure 4 In some embodiments, the heat conducting portion 222 and the light absorbing portion 221 enclose a second accommodating chamber 223 that is connected to the first accommodating chamber 212, wherein the heat conducting portion 222 is cylindrical. The atomizer 200 also includes a stirring member 230, which is accommodated in the second accommodating chamber 223. The stirring member 230 is in contact with the light absorbing portion 221 and / or the heat conducting portion 222. The heat on the light absorbing portion 221 and the heat conducting portion 222 can be transferred to the stirring member 230. The stirring member 230 moves under the heat to stir the atomized medium, thereby accelerating the thermal movement rate of the atomized medium, thereby accelerating the heating and atomization efficiency of the atomized medium. In addition, the stirring of the atomized medium by the stirring member 230 facilitates the discharge of air in the atomized medium to increase the rate at which the atomized medium is converted into an aerosol.

[0054] According to actual needs, the stirring member 230 can be a glass ball, and at least two stirring members 230 are provided, for example, two, three, four glass balls can be provided. The connection between the heat conducting portion 222 and the light absorbing portion 221 is arc-shaped, which improves the smoothness of the movement of the stirring member 230 in the second accommodating chamber 223.

[0055] In some embodiments, the heat conducting part 222 may be in the form of a sheet, and a plurality of heat conducting parts 222 may be distributed continuously or at intervals along the circumferential direction. In this case, the heat conducting part 222 and the light absorbing part 221 are preferably provided separately, and a mounting groove is provided on the light absorbing part 221, and the heat conducting part 222 is inserted into the mounting groove, thereby fixing the heat conducting part 222 on the light absorbing part 221.

[0056] See also Figure 2 , Figure 3 and Figure 4 The atomizer 200 further includes a light absorbing layer 240, which is disposed on the light absorbing portion 221 and in contact with the second cup body 250, so that the heat of the light absorbing layer 240 can be transferred to the second cup body 250, and the second cup body 250 is sleeved on the outside of the first cup body 210, that is, the second cup body 250 is in contact with the outer peripheral wall of the first cup body 210, so that the heat of the second cup body 250 can be transferred to the outer peripheral wall of the first cup body 210, thereby preheating the atomized medium in the first cup body 210, and the paste can be liquefied to facilitate the movement of the stirring member 230. The light-to-heat conversion efficiency of the light absorbing layer 240 is greater than the light-to-heat conversion efficiency of the light absorbing portion 221, thereby increasing the rate at which laser energy is converted into heat, so that the laser emitting assembly 300 gathers more heat at a unit emission output power, thereby rapidly increasing the temperature of the light absorbing portion 221, and effectively improving the atomization efficiency of the light absorbing base 220. According to actual needs, the light absorbing layer 240 may be a light absorbing coating, a light absorbing film, a light absorbing mesh, etc. The light absorbing layer 240 may be made of a black light absorbing material.

[0057] It should be noted that the light absorbing layer 240 may suffer losses (such as the appearance of small white spots) due to excessively high temperature during the atomization process, resulting in reduced light absorption efficiency of the light absorbing layer 240. By setting the light absorbing layer 240 in contact with the second cup body 250, the second cup body 250 can conduct the heat of the light absorbing layer 240 in a timely manner to avoid the temperature of the light absorbing layer 240 from rising, thereby effectively reducing the losses of the light absorbing layer 240 and ensuring the atomization effect.

[0058] See also Figure 2 , Figure 3 and Figure 4, the atomizer 200 also includes a bracket 260 and a nozzle 270. The bracket 260 is provided with an installation cavity, and the first cup body 210 is accommodated in the installation cavity. The nozzle 270 is arranged on the bracket 260, and the nozzle 270 is in sealing contact with the end of the first cup body 210 away from the light absorbing base 220 to prevent leakage of the atomized medium in the first cup body 210; the nozzle 270 is provided with an air outlet channel 271 connected to the first accommodating cavity 212, and the light absorbing base 220 heats the atomized medium in the first accommodating cavity 212 to generate an aerosol, and the aerosol is discharged through the air outlet channel 271 to be inhaled by the user. According to actual needs, the diameter of the air outlet channel 271 is smaller than the diameter of the stirring member 230 to prevent the stirring member 230 from flowing out through the air outlet channel 271.

[0059] See also Figure 3 and Figure 4 The first cup body 210 is provided with a support edge 211 extending from the outer peripheral wall of the first cup body 210 in the radial direction, and the support edge 211 is clamped and fixed by the suction nozzle 270 and the bracket 260, thereby fixing the first cup body 210.

The electronic atomization device also includes a second magnetic steel 900 arranged in the shell 100, and the second magnetic steel 900 and the first magnetic steel 290 are arranged opposite to each other; wherein, the magnetic poles on both sides of the first magnetic steel 290 and the second magnetic steel 900 are arranged oppositely, and when the first magnetic steel 290 and the second magnetic steel 900 are adsorbed together, the atomizer 200 and the shell 100 are connected together; when the first magnetic steel 290 and the second magnetic steel 900 are separated, the atomizer 200 and the shell 100 are separated, thereby realizing a detachable connection between the atomizer 200 and the shell 100. According to actual needs, two groups of the first magnetic steel 290 and the second magnetic steel 900 are provided. The two groups of the first magnetic steel 290 are arranged between the first cup body 210, and the two groups of the second magnetic steel 900 are arranged between the laser emitting assembly 300, and the two groups of the first magnetic steel 290 and the two groups of the second magnetic steel 900 are arranged one by one.

[0067] The atomizer 200 also includes a detection module for detecting the atomized medium. The detection module can detect the amount of atomized medium in the first cup body 210 to prevent the light absorbing base 220 from dry burning when the atomized medium is insufficient. The detection module includes a first sensing electrode and a second sensing electrode electrically connected to the control board 400. The first sensing electrode is arranged on the inner circumferential wall of the first cup body 210, and the first sensing electrode is used to detect the atomized medium on the inner circumferential wall of the first cup body 210; the second sensing electrode is arranged on the light absorbing base 220, and the second sensing electrode is used to detect the atomized medium on the light absorbing base 220. The first sensing electrode and the second sensing electrode do not contact each other. Among them, when the first sensing electrode and the second sensing electrode cannot detect the atomized medium, it is determined that the atomized medium is insufficient at this time, and the laser emitting assembly 300 should be controlled to stop emitting the laser to prevent the light absorbing base 220 from continuing to absorb the laser energy and converting it into heat to cause dry burning.

[0068] In some embodiments, the detection module can be a temperature sensor, which is electrically connected to the control board 400, and is used to detect the temperature of the surface of the light absorbing base 220; wherein, when the temperature sensor detects that the real-time surface temperature value of the light absorbing base 220 is greater than a preset threshold value (the preset threshold value is the temperature value when the light absorbing base 220 normally heats the atomized medium), it is judged that the atomized medium is insufficient at this time, and the laser emitting assembly 300 is controlled to stop emitting the laser to prevent the light absorbing base 220 from continuing to absorb laser energy and converting it into heat, thereby causing dry burning.

[0069] The laser emitting assembly 300 includes a substrate, a laser chip and a driver chip. The substrate is provided with a first surface and a second surface that are relatively distributed; the laser chip is arranged on the first surface of the substrate; the driver chip is arranged on the second surface of the substrate, and the substrate is provided with a clearance hole. The pins of the laser chip are connected to the driver chip through the clearance hole. The driver chip is electrically connected to the control board 400. The control board 400 sends a driving signal to the driver chip, and the driver chip drives the laser chip to emit light according to the driving signal. Among them, the laser chip can be a VCSEL (Vertical-Cavity Surface-Emitting Laser) chip, and a plurality of laser chips are provided, and a plurality of laser chips are arranged in series stacking, so as to increase the laser intensity while minimizing the lateral size of the laser chipset and reducing the cross-sectional area of ​​the electronic atomization device.

[0070] In some embodiments, there are multiple laser emitting components 300. For example, there are three laser emitting components 300, one of which is arranged opposite to the light absorbing part 221 of the light absorbing base 220. The laser emitted by the laser emitting component 300 irradiates the light absorbing part 221. The other two laser emitting components 300 are distributed on the left and right sides of the light absorbing base 220. The lasers emitted by these two laser emitting components 300 irradiate the heat conducting part 222 (the heat conducting part 222 has light absorption). The heat on the light absorbing part 221 and the heat on the heat conducting part 222 can be kept consistent, which can not only improve the atomization uniformity of the atomized medium, but also achieve rapid atomization.

[0071] See also Figure 2The electronic atomization device also includes a fixing frame 500, a battery 600, a button 700 and a heat dissipation assembly 800. The fixing frame 500 is arranged in the housing 100. The battery 600 and the heat dissipation assembly 800 are both fixed to the fixing frame 500 and accommodated in the housing 100. The battery 600 is electrically connected to the control board 400 and the laser emission assembly 300. The battery 600 is used to supply power to the laser emission assembly 300. The heat dissipation assembly 800 is used to cool the laser emission assembly 300 so that the laser emission assembly 300 is within a preferred operating temperature range. The button 700 is arranged on the surface of the housing 100. The button 700 is electrically connected to the control board 400. The button 700 is used to control the electronic atomization device to be in a power-on state or a power-off state. According to actual needs, the laser emitting component 300 can be fixed on the fixing frame 500. The fixing frame 500 is provided with a light-through hole. The laser emitted by the laser emitting component 300 passes through the light-through hole and irradiates the light-absorbing layer 240. The fixing frame 500 is also provided with a groove. The second magnetic steel 900 is fixed in the groove of the fixing frame 500.

[0072] See also Figure 1 , Figure 2 and Figure 3 The heat dissipation component 800 is in contact with the side of the laser emitting component 300 away from the light absorbing base 220. The heat dissipation component 800 serves as a heat dissipation component for the laser chip in the laser emitting component 300. When the laser chip emits a laser, since the laser it emits is a high-energy photon beam, its own surface will also have a local temperature rise rapidly. At this time, since the heat dissipation component 800 is in contact with the laser chip, the heat on the laser chip can be quickly discharged, which effectively reduces the temperature of the laser chip during operation and avoids the situation where the laser chip is scrapped due to local overheating. Among them, the housing 100 is provided with a heat dissipation hole 101, and the heat dissipation hole 101 is arranged opposite to the heat dissipation component 800. The heat carried by the heat dissipation component 800 is transported to the outside of the electronic atomization device through the heat dissipation hole 101, thereby achieving temperature cooling.

[0073] See also Figure 2 and Figure 3 In some embodiments, the fixing frame 500 is further provided with an air-avoiding groove and a light-through hole 501, the air-avoiding groove is adapted to the second cup body 250, and when the atomizer 200 and the housing 100 are connected together, the second cup body 250 is received in the air-avoiding groove to prevent the second cup body 250 from interfering with the connection between the atomizer 200 and the housing 100. The light-through hole 501 is connected to the air-avoiding groove, and the light-through hole 501 is arranged opposite to the light-absorbing part 221 of the light-absorbing base 220, and the laser emitting assembly 300 is arranged opposite to the light-through hole 501, and the laser emitted by the laser emitting assembly 300 passes through the light-through hole 501 and irradiates the light-absorbing part 221 of the light-absorbing base 220.
