Description

Non-contact aerosol generating device and electronic cigarette

[0001] The present application claims priority to the Chinese patent application No. 202410801027.4, filed on June 20, 2024, to the Chinese Patent Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic cigarettes, for example to a non-contact aerosol generating device and electronic cigarette. BACKGROUND

[0003] The electronic cigarette market is rapidly growing, and a common electronic cigarette has main components such as an atomization module, a power module, a controller, and a shell. The atomization module is used to heat the tobacco tar. In the electronic cigarette, an electric heating wire is often used to heat the tobacco tar. After the electric heating wire is powered on, it generates heat, and the generated heat heats the tobacco tar. When the tobacco tar reaches a certain temperature, it is atomized to generate aerosol for the smoker to smoke. However, when the electric heating wire is used to heat the tobacco tar, the electric heating wire is prone to generate heavy metals and other harmful substances when the temperature is too high, thereby affecting the taste of the electronic cigarette and the health of the user due to the unclean electronic cigarette.

[0004] With the increasing concern about the quality of tobacco tar and health, electronic cigarettes that heat tobacco tar by laser have emerged. In the electronic cigarette that heats tobacco tar by laser, the heating source does not need to contact the tobacco tar, and the tobacco tar can be heated and atomized, so that harmful substances are not generated to affect health. In the electronic cigarette that heats tobacco tar by laser, the laser source has a large laser divergence angle and cannot be adjusted, resulting in a low energy density of the laser, which affects the heating rate of the tobacco tar. If the laser power is increased to improve the heating rate of the tobacco tar, the laser module will generate a lot of heat, which makes it difficult to dissipate heat.

[0024] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0026] The embodiment provides a non-contact aerosol generating device, and Figure 1 is a structural schematic diagram of the non-contact aerosol generating device provided by the embodiment of the application. Referring to Figure 1, the non-contact aerosol generating device comprises a power module 1, a laser module 2, an atomizer module 3 and a transparent protective unit 4. The power module 1 is electrically connected with the laser module 2. The power module 1 is configured to supply power to the laser module 2. The laser module 2 is configured to emit laser to the atomizer module 3 when the power module 1 supplies power, so that the atomizer module 3 is rapidly heated to generate aerosol. The transparent protective unit 4 is arranged on the light-emitting surface of the laser module 2. The transparent protective unit 4 is configured to control the divergence angle of the laser emitted by the laser module 2.

[0027] The power module 1 is configured to supply power to the laser module 2, which can include but is not limited to a primary battery such as a dry battery or a button cell, or a secondary battery such as a lithium ion battery or a lead storage battery. In an optional embodiment, the power module 1 can further comprise a direct current-direct current (DC-DC) module to enable an external power supply to directly supply power to the non-contact aerosol generating device.

[0028] In an optional embodiment, the power module 1 comprises a switch, and a user can control the connection state of the power module 1 and the laser module 2 through the switch. When the switch is turned on, the power module 1 is electrically connected with the laser module 2, and the power module 1 can supply power to the laser module 2, so that the non-contact aerosol generating device generates aerosol. When the switch is turned off, the power module 1 is disconnected from the laser module 2, and the power module 1 cannot supply power to the laser module 2, so that the non-contact aerosol generating device does not generate aerosol.

[0029] In an optional embodiment, the atomizer module 3 comprises a tobacco tar tank 31 and a heated target material 32. The tobacco tar tank 31 is provided with a through hole on the side close to the heated target material 32, so that the tobacco tar in the tobacco tar tank 31 can flow to the heated target material 32 through the through hole. The laser emitted by the laser module 2 is irradiated to the heated target material 32 through the transparent protective unit 4, so that the tobacco tar on the heated target material 32 is rapidly heated to form aerosol.

[0030] The laser module 2 can include but is not limited to a laser 21, which is configured to emit laser to the atomizer module 3. It can be understood that the type of the laser 21 is not limited in the embodiment, and the laser 21 can emit laser to the atomizer module 3 to rapidly heat the atomizer module 3 to generate aerosol. In an optional embodiment, the laser 21 can include but is not limited to a vertical cavity surface emitting laser and an edge emitting laser.

[0031] The transparent protective unit 4 can be made of glass, quartz, plastic, silica gel or other high-temperature-resistant and insulating transparent materials, and in an exemplary embodiment, the transparent protective material can withstand a temperature of 300 DEG C. The transparent protective unit 4 covers the light-emitting surface of the laser module 2, and is configured to control the emission angle of the laser emitted by the laser module 2. For example, the emission angle of the laser emitted by the laser module 2 is controlled to be between 10 DEG and 35 DEG, so as to ensure that the power density of the laser emitted by the laser module 2 meets the requirements. In addition, the transparent protective unit 4 also has the function of isolating pollution and water vapor, preventing the laser module 2 from being damaged due to pollution, and improving the service life of the laser module 2.

[0032] In the embodiment, the non-contact aerosol generating device comprises a power module, a laser module, an atomizer module and a transparent protective unit. The power module is electrically connected to the laser module, and the power module is configured to supply power to the laser module. The laser module is configured to emit laser to the atomizer module when the power module supplies power, so as to rapidly heat the atomizer module and generate aerosol. The transparent protective unit covers the light-emitting surface of the laser module, and is configured to control the divergence angle of the laser emitted by the laser module, so that the divergence angle of the laser emitted by the laser module is reduced, which is beneficial to improve the energy density of the laser, thereby improving the heating speed of the atomizer module, rapidly atomizing the tobacco tar in the atomizer module, and improving the generation rate of the aerosol.

[0033] Optionally, the transparent protective unit 4 comprises at least one lens, and the optical axis of the lens is located on a straight line where the laser emitted by the laser module 2 is located, so that the divergence angle of the laser emitted by the laser module 2 can be controlled to meet the requirements by designing the parameters of the lens in the transparent protective unit 4.

[0034] In an optional embodiment, FIG. 2 is a structural schematic diagram of a laser module provided by the embodiment of the present application. As shown in FIG. 2, the laser module 2 comprises a heat dissipation substrate 22, a laser 21 attached to the heat dissipation substrate 22, and a conductive circuit (not shown in the figure). The transparent protective unit 4 covers the light-emitting surface of the laser module 2, and a cavity is provided between the transparent protective unit 4 and the laser 21. Therefore, when the laser emitted by the laser module 2 penetrates the transparent protective unit 4, the transparent protective unit 4 has an incident surface and an exit surface, so that the incident surface and the exit surface of the transparent protective unit 4 can control the divergence angle of the laser emitted by the laser module 2 by designing the lens, which is beneficial to improve the control range and accuracy of the emission angle of the laser, thereby further improving the concentration of the generated aerosol. However, this structure needs to prepare the transparent protective unit 4 first, and then cover the transparent protective unit 4 on the laser module 2, which is a complex process, and the sealing performance of the transparent protective unit 4 is poor.

[0035] In an optional embodiment, FIG. 3 is a structural schematic diagram of another laser module provided by the embodiments of the present application. Referring to FIG. 3, the laser module 2 includes a heat dissipation substrate 22, a laser 21 attached to the heat dissipation substrate 22, and a conductive circuit, etc. The transparent protective unit 4 is arranged on the light emitting surface of the laser module 2, and the transparent protective unit 4 is in contact with the laser 21, so that the light emitting surface of the transparent protective unit 4 can be designed as a lens to control the divergence angle of the laser emitted by the laser module 2. For example, the transparent protective unit 4 is made of silica gel, so that the liquid silica gel can be directly covered on the laser 21, and the liquid silica gel is solidified to obtain the transparent protective unit 4 arranged on the laser module 2, thereby simplifying the preparation process and improving the sealing performance of the transparent protective unit 4.

[0036] Optionally, in combination with the embodiments shown in FIGS. 1-3, the non-contact aerosol generating device further includes a controller 5; the laser module 2 includes at least one laser 21 and a signal acquisition unit 23, the signal acquisition unit 23 is configured to acquire a temperature signal and an electrical signal of the laser 21, the laser 21 and the signal acquisition unit 23 are respectively connected with the controller 5, and the controller 5 is configured to control the output power of the laser 21 according to the temperature signal and the electrical signal acquired by the signal acquisition unit 23 when the laser 21 is working.

[0037] The at least one laser 21 can be understood as one laser 21 or a plurality of lasers 21, and the embodiments are not limited in this regard. When the laser module 2 includes a plurality of lasers 21, the lasers emitted by the plurality of lasers 21 are all irradiated to the atomizer module 3, thereby further improving the generation rate of the aerosol and the taste of the electronic cigarette.

[0038] The signal acquisition unit 23 can include, but is not limited to, a thermistor and a photodiode, etc. The thermistor is configured to acquire a temperature signal of the laser 21, which can be a negative thermistor or a positive thermistor, and the embodiments are not limited in this regard. The photodiode is configured to acquire an electrical signal of the laser 21, thereby detecting the power stability of the laser 21. In an optional embodiment, the electrical signal includes a current signal and / or a voltage signal, and in other embodiments, the electrical signal can further include the power of the laser 21.

[0039] The laser 21 and the signal acquisition unit 23 are respectively connected with the controller 5, which can be electrically connected or communicatively connected with the controller 5, so that the controller 5 can control the output power of the laser 21 according to the temperature signal and the electrical signal acquired by the signal acquisition unit 23 when the laser 21 is working.

[0040] In an optional embodiment, the power module 1 is also electrically connected with the controller 5, and the power module 1 is configured to supply power to the controller 5.

[0041] When the smoker wants to smoke, the switch of the power module 1 can be opened, the power module 1 supplies power to the laser module 2 and the controller 5, the laser emitted by the laser 21 in the laser module 2 irradiates the heated target material 32 of the atomizer module 3 through the transparent protective unit 4, and because the tobacco oil in the tobacco oil tank 31 flows out and reaches the heated target material 32, the tobacco oil on the heated target material 32 rapidly increases in temperature under the irradiation of the laser, and is atomized to form an aerosol. After the switch of the power module 1 is opened, the signal acquisition unit 23 in the laser module 2 acquires the temperature signal and the electrical signal of the laser 21, and sends the temperature signal and the electrical signal to the controller 5, so that the controller 5 controls the power and other working states of the laser 21 according to the temperature signal and the electrical signal. In this way, the non-contact aerosol generating device can be stably heated, so that the generation rate of the aerosol is stable, which is beneficial to further improve the taste of the electronic cigarette, so that the smoker can have a better smoking experience.

[0042] Optionally, as shown in FIGS. 2 and 3, the laser module 2 includes at least one laser 21; the laser 21 is attached to a heat dissipation substrate 22, and the heat dissipation substrate 22 includes a metal substrate 221.

[0043] Optionally, FIG. 4 is a structural schematic diagram of another laser module provided by an embodiment of the present application. As shown in FIG. 4, the laser module 2 includes at least one laser 21; the laser 21 is attached to a heat dissipation substrate 22, and the heat dissipation substrate 22 includes an insulating substrate 224 provided with a heat dissipation plating layer 223.

[0044] The laser 21 attached to the heat dissipation substrate 22 can be understood as that the laser 21 is attached to the heat dissipation substrate 22 by high-thermal-conductivity glue or solder, etc.

[0045] Because the metal substrate 22 has a large thermal conductivity, the laser module 2 can quickly dissipate heat, so that the power of the laser 21 is stable, which is beneficial to improve the stability of the generation rate of the aerosol, thereby further improving the taste of the electronic cigarette, and at the same time, is beneficial to improve the service life of the laser module 2.

[0046] In an optional embodiment, the material of the metal substrate 22 can include, but is not limited to, copper, aluminum or alloys thereof, etc., so as to reduce the cost on the premise of ensuring the heat dissipation efficiency.

[0047] In a use scenario in which the heat dissipation requirement is not strict but the size requirement of the laser module 2 is high, the heat dissipation substrate 22 can include an insulating substrate 224 provided with a heat dissipation plating layer 223, wherein the main material of the insulating substrate 224 can include aluminum nitride, beryllium oxide, silicon carbide, aluminum oxide or diamond, etc., and the heat dissipation plating layer 223 arranged thereon can be a metal material with high heat dissipation efficiency, etc., so that the heat dissipation plating layer 223 can assist the insulating substrate 224 in heat dissipation, so as to improve the heat dissipation efficiency of the laser module 2.

[0048] It can be understood that when the user smokes, due to the high temperature of the atomizer module 3, the aerosol formed by the tobacco tar will suddenly cool down when passing through the mouthpiece 71 communicating with the outside or contacting with the laser module 2 with lower temperature, so that part of the aerosol produces water vapor. If the water vapor condenses on the surface of the transparent protective unit 4, the power density of the outgoing laser will be affected due to the absorption of the laser by the water vapor, thereby affecting the rate of aerosol generation. If the water vapor passes through the mouthpiece 71 together with the aerosol, the smoking taste of the user will be reduced, thereby affecting the user experience. Therefore, the anti-condensation structure can be provided in the non-contact aerosol generating device to eliminate the water vapor, thereby improving the taste of the electronic cigarette.

[0049] Optionally, FIG. 5 is a structural schematic diagram of another laser module provided by an embodiment of the present application. As shown in FIG. 5, the anti-condensation structure 6 includes a transparent conductive film 61 arranged on the surface of the transparent protective unit 4; the power supply module 1 is electrically connected with the transparent conductive film 61; and the power supply module 1 is arranged to supply power to the transparent conductive film 61.

[0050] The transparent conductive film 61 can include, but is not limited to, at least one of an indium tin oxide transparent conductive film, an aluminum-doped zinc oxide transparent conductive film, a boron-doped zinc oxide transparent conductive film, and a gallium-doped zinc oxide transparent conductive film.

[0051] The power supply module 1 is electrically connected with the transparent conductive film 61 to supply power to the transparent conductive film 61. Since the transparent conductive film 61 has poor conductivity, it will generate heat when powered on, so that the surface of the transparent protective unit 4 will not condense water vapor, thereby not affecting the power density of the outgoing laser, and further ensuring the rate of aerosol generation.

[0052] In an optional embodiment, the transparent conductive film 61 is in contact with the conductive circuit of the laser module 2, so that the power supply module 1 can supply power to the transparent conductive film 61 through the conductive circuit. The transparent conductive film 61 and the conductive circuit are fixed by the conductive adhesive 611, so that the transparent conductive film 61 is in stable contact with the conductive circuit, thereby improving the stability of the circuit.

[0053] Optionally, FIG. 6 is a structural schematic diagram of another non-contact aerosol generating device provided by an embodiment of the present application. As shown in FIG. 6, the atomizer module 3 includes a heated target material 32; and the transparent protective unit 4 is in contact with the heated target material 32 to form the anti-condensation structure 6.

[0054] The heated target material 32 can be a fiber material, thereby capable of absorbing the tobacco tar and not forming dew. The transparent protective unit 4 is in contact with the heated target material 32 to form the anti-dew structure 6, so that the heat of the heated target material 32 is transferred to the transparent protective unit 4, the temperature of the transparent protective unit 4 is increased, so that the surface of the transparent protective unit 4 does not condense water vapor, thereby not affecting the power density of the outgoing laser, and further ensuring the rate of aerosol generation. It should be noted that by contacting the transparent protective unit 4 with the heated target material 32, the heat of the heated target material 32 is transferred to the transparent protective unit 4, and the temperature of the two sides of the transparent protective unit 4 will not be significantly increased, so that the two sides of the transparent protective unit 4 may condense water vapor, but the two sides of the transparent protective unit 4 do not emit laser, so it will not affect the power density of the outgoing laser.

[0055] Optionally, FIG. 7 is a structural schematic diagram of another non-contact aerosol generating device provided by the embodiment of the present application. Referring to FIG. 7, the non-contact aerosol generating device further includes a housing 7; the power supply module 1, the laser module 2, the atomizer module 3 and the transparent protective unit 4 are accommodated in the housing 7, and the power supply module 1, the laser module 2 and the atomizer module 3 are arranged along a first direction L1; at least the atomizer module 3 and the housing 7 on both sides of the atomizer module 3 are respectively provided with a first airflow guide plate 81 and a second airflow guide plate 82 extending along the first direction L1, so as to form an airflow channel 8 between the first airflow guide plate 81 and the second airflow guide plate 82.

[0056] The housing 7 is arranged to protect the power supply module 1, the laser module 2, the atomizer module 3 and the transparent protective unit 4 in the non-contact aerosol generating device, and to make the multiple parts of the non-contact aerosol generating device assembled to form a whole, thereby facilitating carrying, and improving the aesthetic appearance of the non-contact aerosol generating device. In an optional embodiment, the housing 7 can be in a cylindrical shape, so that the shape of the housing 7 is more regular and facilitates molding and manufacturing, and the shape of the electronic cigarette is closer to that of a cigarette, thereby improving the sensory experience of the smoker.

[0057] The first airflow guide plate 81 and the second airflow guide plate 82 extend along the arrangement direction of the laser module 2 and the atomizer module 3, so that the airflow can be distributed around the laser module 2, rather than being concentrated at the heated target material 32 of the atomizer module 3, thereby reducing the heat loss of the heated target material 32, and facilitating further improving the generation rate of the aerosol.

[0058] Optionally, continuing to refer to FIG. 7, the anti-dew structure 6 includes a water-absorbing and air-permeable material 62; the water-absorbing and air-permeable material 62 is arranged between the atomizer module 3 and the first airflow guide plate 81, and between the atomizer module 3 and the second airflow guide plate 82.

[0059] The water-absorbing and air-permeable material 62 may, but is not limited to, include an expanded polytetrafluoroethylene film or the like, so that the anti-condensation structure 6 can absorb water vapor while ensuring the smoothness of the gas flow in the airflow channel 8. In an optional embodiment, the thickness of the water-absorbing and air-permeable material 62 in the first direction L1 can be set according to actual needs. When the thickness is too small, the water vapor absorption capacity is poor, and a better water vapor absorption effect cannot be achieved. When the thickness is too large, the smoothness of the gas flow in the airflow channel 8 is poor, thereby affecting the experience of the smoker. In an exemplary embodiment, the thickness of the water-absorbing and air-permeable material 62 in the first direction L1 can be 0.5 cm, so that the water vapor absorption capacity can be ensured, and the smoothness of the gas flow in the airflow channel 8 will not be affected, thereby further improving the taste of the electronic cigarette.

[0060] Based on the same inventive concept, the embodiments of the present application also provide an electronic cigarette, which includes the non-contact aerosol generating device provided by any of the above embodiments.

[0061] Since the electronic cigarette provided by the embodiments of the present application includes the non-contact aerosol generating device provided by the embodiments, it has the corresponding structures and features of the non-contact aerosol generating device, and the same parts can be referred to the description above.
