Description

Technical Field

[0001] This utility model relates to the technical field of aerosol generation devices, and in particular to a laser module and an aerosol generation device. Background Technology

[0002] The aerosol generation device includes a laser module comprising multiple emitters. These emitters are linearly arranged and irradiate the aerosol generation matrix. The edge portion of the aerosol generation matrix irradiated by the laser module exchanges heat with the outside, resulting in a lower temperature in this area compared to the central portion irradiated by the laser module. Increasing the emitter power can ensure adequate heating of the edge portion of the aerosol generation matrix irradiated by the laser module. However, this may lead to excessively high temperatures in the central portion of the aerosol generation matrix irradiated by the laser module, potentially causing scorching. Utility Model Content

[0003] This invention provides a laser module and an aerosol generating device to solve at least one of the aforementioned technical problems.

[0004] The laser module of this invention is used in an aerosol generating device. The laser module includes an emitter group, which includes multiple emitters arranged linearly with essentially the same emission direction. The multiple emitters include two edge emitters and at least two intermediate emitters. The at least two intermediate emitters are disposed between the two edge emitters. The distance between an edge emitter and an adjacent intermediate emitter is less than the distance between two adjacent intermediate emitters.

[0005] When a laser module is used in an aerosol generation device, edge emitters and intermediate emitters irradiate the aerosol generation matrix to heat it. In the laser module of this embodiment, because the distance between the edge emitters and the adjacent intermediate emitters is small, even if the edge portion of the aerosol generation matrix irradiated by the laser module exchanges heat with the external environment, the temperature of the edge portion of the aerosol generation matrix will not be too low. This is because the smaller distance allows the heat from the emitters to be transferred more concentratedly to the edge portion of the aerosol generation matrix, compensating for the temperature drop caused by heat exchange with the outside. Therefore, the heating quality of the edge portion of the aerosol generation matrix is ​​guaranteed, and there is no need to excessively increase the power of the emitters to compensate for insufficient temperature of the edge portion of the aerosol generation matrix. In this way, the temperature of the intermediate portion of the aerosol generation matrix can be avoided due to excessively increasing the emitter power, thereby preventing scorching of the intermediate portion of the aerosol generation matrix irradiated by the laser module.

[0006] In some implementations, the distance between two adjacent transmitters gradually decreases from the two edge transmitters toward the center of the two edge transmitters.

[0007] In some embodiments, the plurality of transmitters are substantially symmetrical about the centerline of the two edge transmitters, and the emission directions of the plurality of transmitters are substantially the same.

[0008] In some embodiments, the laser module includes a row of emitters, which includes multiple groups of emitters. The emitters in the same row are linearly arranged and have substantially the same emission direction. The multiple groups of emitters in the same row are sequentially excited.

[0009] In some embodiments, the laser module includes multiple rows of emitters, the lines connecting the corresponding emitters in the multiple rows of emitters are substantially parallel and aligned, and the emission directions of the corresponding emitters in the multiple rows of emitters are substantially the same.

[0010] In some embodiments, the laser module further includes a substrate and a light-transmitting protective element, the emitter and the light-transmitting protective element being disposed on the substrate, the light-transmitting protective element and the substrate forming an accommodating space, and the emitter being disposed within the accommodating space.

[0011] In some embodiments, the substrate is further provided with electrodes, which are electrically connected to the transmitter.

[0012] In some embodiments, the number of electrodes is multiple, and the laser module includes multiple emitter rows, including a first emitter row and a second emitter row. The first emitter row is disposed between the electrodes and the second emitter row, and the emitters in the second emitter row are electrically connected to the electrodes through the corresponding emitters in the first emitter row.

[0013] In some embodiments, the aerosol generating apparatus includes a laser module and an aerosol generating matrix as described in any of the above embodiments, wherein the laser module is used to emit a laser toward the aerosol generating matrix.

[0014] In some embodiments, the distance between the transmitter and the aerosol generating matrix ranges from [2 mm to 5 mm].

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The aerosol generating device 100 of this utility model includes a laser module and an aerosol generating matrix 20. The laser module 10 is used to emit lasers toward the aerosol generating matrix 20.

[0034] The aerosol generating device 100 is a device for generating aerosols and can be used in fields such as atomizers. The aerosol generating device 100 generates an aerosol that can be inhaled by a user by heating the aerosol generating matrix 20. The emitter 11 is used in the aerosol generating device 100 to heat the aerosol generating matrix 20 using a laser to form an aerosol.

[0035] The aerosol generating matrix 20 can be in liquid, solid, or semi-solid form. For example, the aerosol generating matrix 20 can be propylene glycol, glycerin, and nicotine; or it can be a solid substance containing tobacco or herbal ingredients. Under the heating action of the laser module 10, the aerosol generating matrix 20 releases aerosols. The aerosols generated in the aerosol generating device 100 can be used for various purposes such as food, medicine, and industrial production. The laser module 10 irradiates and heats the aerosol generating matrix 20. This can be done by directly irradiating the aerosol generating matrix 20 with the laser module 10, or by irradiating an intermediate element with the laser module 10, which then conducts heat to the aerosol generating matrix 20. No limitation is made here. In one example, the intermediate element and the aerosol generating matrix 20 together constitute an aerosol-generated product for user use.

[0036] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The laser module 10 of this utility model includes an emitter group 11z, which includes multiple emitters 11. The multiple emitters 11 are linearly arranged and have basically the same emission direction. The multiple emitters 11 include two edge emitters 11b and at least two intermediate emitters 11m. The at least two intermediate emitters 11m are disposed between the two edge emitters 11b. The distance between the edge emitter 11b and the adjacent intermediate emitter 11m is smaller than the distance between the two adjacent intermediate emitters 11m.

[0037] Edge emitters 11b and intermediate emitters 11m irradiate the aerosol generating matrix 20 to heat it. In the laser module 10 of this embodiment, because the distance between the edge emitter 11b and the adjacent intermediate emitter 11m is small, even if the edge portion of the aerosol generating matrix 20 irradiated by the laser module 10 exchanges heat with the external environment, the temperature of the edge portion of the aerosol generating matrix 20 will not be too low. This is because the smaller distance allows the heat from the emitter 11 to be transferred more concentratedly to the edge portion of the aerosol generating matrix 20, compensating for the temperature drop of the edge portion of the aerosol generating matrix 20 caused by heat exchange with the outside. Therefore, the heating quality of the edge portion of the aerosol generating matrix 20 is guaranteed, and there is no need to compensate for insufficient temperature of the edge portion of the aerosol generating matrix 20 by excessively increasing the power of the emitter 11. In this way, the temperature of the intermediate portion of the aerosol generating matrix 20 can be avoided from becoming too high due to excessively increasing the power of the emitter 11, thereby preventing scorching of the intermediate portion of the aerosol generating matrix 20 irradiated by the laser module 10.

[0038] Specifically, the laser module 10 is used to emit laser light to achieve specific functions, such as heating and cutting. For ease of explanation, this embodiment of the invention will be described using the laser module 10 applied to the aerosol generating device 100. The laser module 10 is used to emit laser light onto the aerosol generating matrix 20 to achieve the heating function.

[0039] Emitter group 11z refers to a group of transmitters 11 working together to output a specific beam of light. Emitter group 11z heats the target area uniformly through the coordinated operation of multiple transmitters 11. There can be one or more emitter groups 11z. Different emitter groups 11z can contain the same or different numbers of transmitters 11.

[0040] The emitter 11 can be a laser diode, a laser chip, or other type of laser emitting element. For example, the emitter 11 can be a laser chip, which can be used to irradiate the aerosol generating matrix 20 and form a light spot T on the aerosol generating matrix 20. The shape of the light spot T can be circular, square, or other shapes. As an example, Figure 4 and Figure 5 This shows the case where the light spot is square.

[0041] Laser module 10 can include different types such as semiconductor lasers, solid-state lasers or fiber lasers, and the specific choice depends on the application scenario and performance requirements.

[0042] Linear arrangement refers to multiple emitters 11 arranged in a straight line. A linear arrangement of emitters 11 ensures that the laser beam is output in a specific direction, facilitating uniform heating of the target area. "Emitting directions are basically the same" means that the beam directions of all emitters 11 are approximately the same. This ensures that the laser beam can be concentrated on the target area, improving heating efficiency and reducing the gaps between laser beams, thus increasing the utilization rate of the aerosol generation matrix 20.

[0043] Edge transmitters 11b refer to transmitters 11 located at both ends of transmitter group 11z. Intermediate transmitters 11m refer to transmitters 11 located inside transmitter group 11z. Edge transmitters 11b and intermediate transmitters 11m can have the same power. The number of intermediate transmitters 11m can be two, three, four, or even more. The distance between adjacent intermediate transmitters 11m can be equal or unequal. The distance between two edge transmitters 11b and their respective adjacent intermediate transmitters 11m can be equal or unequal.

[0044] By setting the distance between the edge emitter 11b and the adjacent intermediate emitter 11m to be smaller than the distance between two adjacent intermediate emitters 11m, the reduced temperature in the region of the aerosol generation matrix 20 corresponding to the edge emitter 11b can be compensated. Simultaneously, it can prevent the aerosol generation matrix 20 from overheating due to excessively increased power of the emitter 11, thus avoiding scorching. For example, if the distance between adjacent intermediate emitters 11m is 2.3mm, the distance between the edge emitter 11b and the intermediate emitters 11m can be set to 2mm.

[0045] In other embodiments, if the space of the laser module 10 is limited, the distance between at least two adjacent intermediate emitters 11m can be set to be greater than the distance between the edge emitter 11b and the adjacent intermediate emitter 11m. For example, the distance between two adjacent intermediate emitters 11m is equal to the distance between the edge emitter 11b and the adjacent intermediate emitter 11m, and the distance between two adjacent intermediate emitters 11m is greater than the distance between the edge emitter 11b and the adjacent intermediate emitter 11m, or in other words, the distance between at least two adjacent intermediate emitters 11m is greater than the distance between the edge emitter 11b and the adjacent intermediate emitter 11m.

[0046] Please refer to Figure 3 , Figure 4 and Figure 5, in some embodiments, the distance between two adjacent emitters 11 gradually decreases in the direction from the two edge emitters 11b towards the center of the two edge emitters 11b.

[0047] Thus, through the spacing distribution that gradually decreases from the edge to the center, the laser emitted by the emitters 11 as a whole is more uniform, thereby reducing the temperature gradient of the irradiated area of the aerosol - generating substrate 20, making the temperature of the irradiated area of the aerosol - generating substrate 20 more uniform, and thus improving the heating quality of the emitters 11.

[0048] Specifically, the middle emitter 11m may include a first emitter 110m, a second emitter 111m, and a third emitter 112m that are arranged adjacent to each other, and the second emitter 111m is located between the first emitter 110m and the third emitter 112m. The first emitter 110m is arranged adjacent to the edge emitter 11b.

[0049] The distance between the first emitter 110m and the edge emitter 11b is the first distance L1. The distance between the second emitter 111m and the first emitter 110m is the second distance L2. The distance between the third emitter 112m and the second emitter 111m is L3. Among them, L1 < L2 < L3. For example, L1 may be 2 mm, L2 may be 2.1 mm, and L3 may be 2.3 mm. In this way, the temperature of each area of the aerosol - generating substrate 20 irradiated by the emitters 11 is more uniform, and the probability that the aerosol - generating substrate 20 produces a burnt smell is relatively low.

[0050] The distance between two adjacent emitters 11 may refer to the distance between the geometric centers of two adjacent emitters 11.

[0051] Please refer to Figure 3 , in some embodiments, the multiple emitters 11 are substantially symmetric about the mid - line of the two edge emitters 11b.

[0052] Thus, the symmetric layout makes the heat emitted by the emitters 11 on both sides of the mid - line equivalent, thereby avoiding the situation where the temperature of the aerosol - generating substrate 20 in the corresponding areas is inconsistent, and thus achieving a more uniform heating effect.

[0053] Specifically, the mid - line of the two edge emitters 11b may be the perpendicular bisector of the line connecting the geometric centers of the two edge emitters 11b. Figure 3 The mid - line is shown as a dashed line a, but it should be noted that this is only a schematic for easy understanding and cannot be used as a limitation on the embodiments of the present utility model.

[0054] [[ID= 28]]Please refer to Figure 3 、 Figure 4 和 Figure 5In some embodiments, the laser module 10 includes a transmitter row 11p, which includes multiple transmitter groups 11z. The transmitters 11 of the same transmitter row 11p are linearly arranged and have basically the same emission direction. The multiple transmitter groups 11z of the same transmitter row 11p are excited sequentially.

[0055] Thus, when the laser module 10 is applied to the aerosol generating device 100, multiple emitter groups 11z of the same emitter row 11p in the laser module 10 are set to be excited sequentially, which can meet the user's multiple suction needs.

[0056] For example, during the user's first puff, the first emitter group 11z is activated, providing an appropriate amount of aerosol; during the user's second puff, the second emitter group 11z is activated, continuing to provide aerosol; and so on, until the Nth puff, when the Nth emitter group 11z is activated. This design ensures that a fresh and appropriate amount of aerosol is provided with each puff, avoiding waste or a decline in taste caused by excessive heating at once, thus significantly improving the user experience.

[0057] The sequential activation of the emitter groups 11z enables a "suck-and-heat" function. Each time aspiration occurs, only the corresponding number of emitter groups 11z are activated, making aerosol generation more immediate and reducing waiting time. Furthermore, by activating the emitter groups 11z on demand, the corresponding emitter groups 11z consume energy at different times, avoiding unnecessary energy waste. This design significantly reduces the overall energy consumption of the aerosol generation device 100 and extends its operating time.

[0058] Furthermore, by dividing the emitter 11 into multiple groups and sequentially activating these groups, segmented heating of the aerosol generation matrix 20 can be achieved. Segmented heating avoids the aerosol generation matrix 20 from experiencing excessively high temperature changes in a short period of time, thereby reducing the generation of thermal stress. By reducing thermal stress, thermal damage to the aerosol generation matrix 20 can be reduced, thus extending its service life.

[0059] Specifically, different emitter groups 11z in the same emitter row 11p are used to heat different portions of the aerosol generation matrix 20. The number of emitter groups 11z in the same emitter row 11p can be two, three, four, or even more. As an example, Figure 3 The diagram illustrates a configuration where an emitter array 11p comprises two emitter groups 11z, with both groups extending in the same direction. This allows the laser beams emitted by the two emitter groups 11z to be more closely spaced, resulting in more uniform heating and improved utilization of the aerosol generation matrix 20.

[0060] Please refer to Figure 6, Figure 7 and Figure 8 In some embodiments, the laser module 10 includes multiple emitter rows 11p, the lines connecting the corresponding emitters 11 of the multiple emitter rows 11p are substantially parallel and aligned, and the emission directions of the corresponding emitters 11 of the multiple emitter rows 11p are substantially the same.

[0061] In this way, multiple rows of emitters 11 can simultaneously or sequentially heat the aerosol generating matrix 20, achieving a more efficient heating effect. Because the lines connecting the corresponding emitters 11 are parallel and aligned, the heating areas of the multiple rows of emitters 11 are more compact, resulting in more uniform heating. Furthermore, the compact heating area improves the utilization rate of the aerosol generating matrix 20, reducing the possibility of some areas of the aerosol generating matrix 20 not being irradiated by the emitters 11.

[0062] Specifically, the number of transmitter rows 11p can be two, three, four, or even more. As an example, Figure 6 and Figure 7 The diagram illustrates a configuration with two emitter rows 11p, which can be arranged along the width of the laser module 10. The width of the laser module 10 can be perpendicular to the extending direction of the emitter rows 11p. This results in a more compact heating area between the two emitter rows 11p, leading to more uniform heating and improved utilization of the aerosol generation matrix 20.

[0063] The connection between the corresponding transmitters 11 of multiple transmitter rows 11p is in Figure 7 The figures are shown with dashed lines b and c, but this is only for illustrative purposes and should not be construed as limiting the embodiments of this utility model.

[0064] Please refer to Figure 6 In some implementations, the distance M between two adjacent transmitter rows 11p ranges from [1mm, 2mm].

[0065] Thus, by limiting the distance M between adjacent emitter rows 11p to [1mm, 2mm], it can be ensured that the irradiation range of each emitter 11 is neither too large nor too small. By limiting the upper limit to 2mm, it can be ensured that the emitter 11 can achieve effective heating with a low energy output.

[0066] By limiting the lower limit to 1 mm, the possibility of overlapping irradiation areas of the emitter 11 can be reduced, thereby reducing the probability of excessively high local temperature of the aerosol generation matrix 20 due to overlapping irradiation areas, maintaining the quality and taste of the aerosol, and preventing the aerosol generation matrix 20 from producing a burnt taste.

[0067] Specifically, the distance M between two adjacent transmitter rows 11p can range from [1mm, 1.9mm], [1.2mm, 1.8mm], [1.5mm, 1.6mm], [1.6mm, 1.8mm], [1.6mm, 2mm], etc.

[0068] The distance M between two adjacent transmitter rows 11p can refer to the distance between the center lines of two adjacent transmitter rows 11p.

[0069] Please refer to Figure 3 and Figure 6 In some embodiments, the laser module 10 further includes a substrate 12 and a light-transmitting protective element 13. The emitter 11 and the light-transmitting protective element 13 are disposed on the substrate 12. The light-transmitting protective element 13 and the substrate 12 form an accommodating space, and the emitter 11 is disposed within the accommodating space.

[0070] In this way, the light-transmitting protective component 13 allows the laser to pass through smoothly and prevents impurities such as dust and moisture from entering the transmitter 11 area, reducing transmitter 11 malfunctions caused by environmental factors and thus extending the service life of the transmitter 11.

[0071] Specifically, substrate 12 is a physical platform used to support and fix transmitter 11 and other components. Substrate 12 can be a printed circuit board. Substrate 12 can be made of ceramic material to give it good insulation properties.

[0072] The transmitter 11 can be mounted on the substrate 12 by bonding, welding or other fixing methods.

[0073] The light-transmitting protective element 13 protects the emitter 11 from external environmental influences and allows laser light to pass through. For example, the light-transmitting protective element 13 can be a cap-like structure made of optical silicone material, the edges of which can be adhered to the substrate 12. Alternatively, the light-transmitting protective element 13 can include a light-transmitting portion and a metal support portion formed on the substrate 12. The metal support portion can have an opening for laser light to pass through, and the light-transmitting portion can cover the opening. The light-transmitting portion can be made of materials such as optical glass, quartz glass, or transparent plastic.

[0074] Please refer to Figure 3 and Figure 6 In some embodiments, the substrate 12 is further provided with an electrode 14, which is electrically connected to the transmitter 11.

[0075] Thus, electrode 14, as a conductive component, can provide a stable current supply to transmitter 11, reducing power fluctuations caused by poor contact or unstable electrical connections. Electrode 14 can also serve as an intermediate component, allowing external controllers or control circuits to control parameters such as the power and irradiation time of transmitter 11.

[0076] Specifically, electrode 14 can be made of copper, aluminum, or other conductive materials. Electrode 14 can be electroplated onto substrate 12.

[0077] As an example, such as Figure 3 As shown, when the light-transmitting protective element 13 is a cap-like structure made of optical silicone material, the light-transmitting protective element 13 can directly contact the electrode 14. As an example, such as... Figure 6 As shown, when the light-transmitting protective member 13 may include a light-transmitting portion and a metal support portion formed on the substrate 12, the light-transmitting protective member 13 may be isolated from the electrode 14 to prevent the electrode 14 from contacting the metal support portion and causing a short circuit.

[0078] In some embodiments, the transmitter 11 is bonded to the electrode 14.

[0079] Thus, the bonding method ensures that the transmitter 11 will not shift due to vibration or mechanical impact during operation, thereby improving the stability of the transmitter 11. Furthermore, the bonding method reduces the complexity of the assembly process, reduces the use of fasteners, thereby improving assembly efficiency and reducing manufacturing costs.

[0080] When the transmitter 11 is bonded to the electrode 14 using conductive and thermally conductive adhesive, the thermally conductive adhesive can improve the heat conduction efficiency between the transmitter 11 and the electrode 14, thereby reducing the heat accumulation generated when the transmitter 11 is working and further extending the service life of the transmitter 11.

[0081] Specifically, bonding refers to the process of fixing the transmitter 11 to the electrode 14 using an adhesive material. The adhesive material can be silver paste, which is a conductive adhesive that can be used for electrical connection between the transmitter 11 and other components disposed on the electrode 14.

[0082] Please refer to Figure 6 In some embodiments, there are multiple electrodes 14, and the laser module 10 includes multiple emitter rows 11p. The multiple emitter rows 11p include a first emitter row 110p and a second emitter row 111p. The first emitter row 110p is disposed between the electrodes 14 and the second emitter row 111p, and the emitters 11 in the second emitter row 111p are electrically connected to the electrodes 14 through the corresponding emitters 11 in the first emitter row 110p.

[0083] Thus, by using the transmitter 11 in the first transmitter row 110p as an intermediate connection point, the second transmitter row 111p can be indirectly electrically connected to the electrode 14. This layered connection method reduces the need for direct connection, reduces the complexity of electrical connection, and reduces the connection structure between the transmitter 11 in the first transmitter row 110p and the electrode 14, thereby reducing the manufacturing cost of the laser module 10.

[0084] Specifically, the number of electrodes 14 can be two, three, four, or even more. For example, there can be five electrodes 14, which can be arranged along the extension direction of the transmitter row 11p. One electrode 14 can be connected to multiple transmitters 11. Multiple terminals or pins for connecting to the transmitters 11 can be provided on the electrode 14. The terminals or pins can be connected to the electrodes of the transmitters 11 through connection structures such as gold wire.

[0085] The aerosol generating apparatus 100 may further include a housing 30 and a mounting chamber 40. The mounting chamber 40 is detachably connected to the housing 30. The laser module 10 may be disposed within the housing 30. The aerosol generating matrix 20 is mounted within the mounting chamber 40. The mounting chamber 40 may be provided with a light-transmitting hole 41. The laser emitted by the emitter 11 toward the aerosol generating matrix 20 can pass through the light-transmitting hole 41.

[0086] Please refer to Figure 5 and Figure 8 In some embodiments, the distance D between the emitter 11 and the aerosol generating matrix 20 ranges from [2 mm to 5 mm].

[0087] Thus, by limiting the distance range to [2mm, 5mm], the laser energy is efficiently transferred to the aerosol generation matrix 20 while avoiding local overheating. By setting the upper limit to 5mm, the area of ​​the light spot formed by the emitter 11 on the aerosol generation matrix 20 will increase, resulting in energy dispersion and ineffective heating of the aerosol generation matrix 20, thus affecting the aerosol generation efficiency and quality.

[0088] By setting a lower limit of 2mm, the probability of mechanical interference between the emitter 11 and the aerosol generating matrix 20 can be reduced, thereby reducing the probability of damage to the emitter 11. Furthermore, the laser energy emitted by the emitter 11 will not be overly concentrated, which facilitates adjusting the heating intensity according to user needs, thereby adjusting the taste of the aerosol, and reducing the likelihood of the aerosol generating matrix 20 producing a burnt taste.

[0089] Specifically, the distance D between the emitter 11 and the aerosol generating matrix 20 can range from [2mm, 4.5mm], [1.5mm, 4mm], [2.5mm, 3mm], [2.5mm, 4.5mm], [2.5mm, 5mm], etc.

[0090] The distance D between the transmitter 11 and the aerosol generating matrix 20 can refer to the minimum distance between the transmitter 11 and the aerosol generating matrix 20.
