Description

Laser cigarette lighter device and preparation method thereof

[0001] This application claims priority to the U.S. provisional patent application serial number 63 / 472,782 filed on June 13, 2023, and priority to the Chinese patent application filed with the China Patent Office on August 18, 2023, with application number 202311052241.6. The entire contents of the above applications are incorporated herein by reference. Technical Field

[0002] The embodiments of the present application relate to the field of laser technology, for example, to a laser cigarette lighter device and a preparation method thereof. Background Art

[0003] E-cigarettes are electronic products that mimic cigarettes, with the same appearance, smoke, taste, and feel as cigarettes. They convert nicotine and other substances into vapor through atomization and other means, which are then inhaled by the user.

[0004] E-cigarettes primarily use electrode heating and electronic induction coil heating. For electrode heating, electrodes are typically plated on a ceramic surface and processed into a "dagger" shape for insertion into tobacco leaves or e-liquid, which are then atomized. However, electrode heating can cause the temperature of the tobacco leaves or e-liquid to reach 200-300°C, causing them to release a variety of harmful substances. Electronic induction coil heating, on the other hand, allows for a higher temperature to prevent the release of these harmful substances. However, both ceramics, metal electrodes plated on ceramic surfaces, and electronic induction coils, as well as heavy metal materials, release harmful substances over time or during dry burning. These substances, when inhaled into the body after atomization, can harm smokers and are also environmentally unfriendly.

[0049] An embodiment of the present application provides a laser cigarette lighting device. Figure 1 is a structural schematic diagram of a laser cigarette lighting device provided by an embodiment of the present application, Figure 2 is a disassembled diagram of the structure shown in Figure 1, and Figure 3 is a bottom schematic diagram of the structure shown in Figure 2. Referring to Figures 1 to 3, the laser cigarette lighting device includes: a shell 10; a light-transmitting container 20, located in the shell 10; a laser emitting unit, including a plurality of lasers 30; the plurality of lasers 30 are arranged between the shell 10 and the light-transmitting container 20, and the light emitting direction of the laser 30 is toward the light-transmitting container 20; wherein, the light-transmitting container 20 is provided with a raw material to be atomized and a heat-absorbing material, and the laser 30 is configured to heat and atomize the raw material to be atomized; the heat-absorbing material is configured to absorb heat to increase the degree of atomization of the raw material to be atomized.

[0050] The laser cigarette lighting device includes a shell 10, a light-transmitting container 20 and a laser emitting unit. The light-transmitting container 20 is configured to accommodate the raw materials to be atomized. The raw materials to be atomized may include solid smoke or liquid smoke, or other raw materials that can be heated and inhaled for entertainment or medical purposes, which is not limited in the embodiments of the present application. The light-transmitting container 20 is arranged in the shell 10, and a plurality of lasers 30 are fixed on the inner surface of the shell 10, so that a plurality of lasers 30 with light emitting directions facing the light-transmitting container 20 are arranged around or at the bottom of the light-transmitting container 20. Through the coherent light advantage of the laser, the heat of the laser is transferred to the raw materials to be atomized, so that the raw materials to be atomized are heated and atomized. The material of the light-transmitting container 20 includes one or more of glass, silicon carbide, ceramics, oxides and nitrides, which must meet the requirement of being transparent to the laser.

[0051] The shell 10 can be cylindrical, spherical, or cubic. The light-transmitting container 20 can be cylindrical, elongated, or pan-like. FIG1 exemplarily shows the light-transmitting container 20 as a cylindrical shape, FIG4 exemplarily shows the light-transmitting container 20 as a pan shape, and FIG5 exemplarily shows the light-transmitting container 20 as an elongated shape. In the cross-section of the shell 10, along the edge of the pattern formed by the shell 10, the lasers 30 can be arranged unilaterally, bilaterally, or multilaterally. Preferably, these lasers 30 can be evenly arranged on the outer ring of the light-transmitting container 20, so that the energy of the lasers 30 can be more evenly transferred to the raw material to be atomized.

[0052] The light-transmitting container 20 is also equipped with a heat-absorbing material that does not decompose above 200°C and can effectively absorb the heat of the laser. Such materials include graphite, silicon carbide, ceramics, metals, oxides, and nitrides, which have high absorption peaks between 650-1550nm. These heat-absorbing materials are configured to absorb heat from the laser and transfer it to the liquid or tobacco material to be atomized, facilitating the atomization of the material.

[0053] The laser cigarette lighting device provided in the embodiment of the present application uses the coherent light advantage of the laser to transfer the heat of the laser to the raw material to be atomized, thereby heating and atomizing the raw material to be atomized. The temperature of the laser heating can prevent the raw material to be atomized from releasing various types of substances harmful to the human body, and can also reduce or avoid the release of harmful substances from materials such as ceramics and metal electrodes in the device. In addition, the laser is used as a heating source and is arranged outside the light-transmitting container, which can prevent the laser from directly contacting the raw material to be atomized, solve the problem of increased heat loss caused by the raw material to be atomized covering the electrode or electronic coil, and reduce or avoid the harmful substances released by materials such as ceramics and metal electrodes being inhaled into the body with the atomized raw material, thereby reducing the harm caused to the smoker himself and improving the environmental friendliness of the electronic cigarette. In addition, a heat-absorbing material is provided in the light-transmitting container, which can increase the atomization degree of the raw material to be atomized, thereby improving the user experience.

[0054] In one embodiment of the present application, optionally, at least part of the heat absorbing material is in powder form, and the powdered heat absorbing material is uniformly mixed in the raw material to be atomized.

[0055] A heat-absorbing material that is resistant to decomposition and effectively absorbs laser heat is also disposed within the light-transmitting container 20. The added heat-absorbing material exhibits an absorption peak exceeding a preset value within the wavelength range of 650-1550 nm. Examples of such materials include silicon carbide powder, graphite powder, ceramic powder, metal powder, oxide powder, nitride powder, and nitride powder, each exhibiting a high absorption peak between 650-1550 nm. The powdered heat-absorbing material can be evenly mixed with the raw material to be atomized, ensuring more uniform heat transfer to the raw material, thereby achieving sufficient heating and atomization of the raw material.

[0056] In one embodiment of the present application, Figure 6 is a structural schematic diagram of a porous loose structure provided in an embodiment of the present application. Referring to Figure 6, at least part of the heat-absorbing material constitutes the porous loose structure 103, and the raw material to be atomized is filled in the pores 104 of the porous loose structure 103.

[0057] Figure 7 is a schematic structural diagram of a heat absorber provided in an embodiment of the present application. Referring to Figure 7, optionally, at least a portion of the heat absorbing material constitutes the heat absorber 101; the heat absorber 101 includes at least one hollow cavity 100 configured to accommodate the raw material to be atomized; the heat absorber 101 has a columnar structure, a spherical structure or a cubic structure; the shape of the hollow cavity 100 includes one or more of a circular, annular, elliptical, polygonal and irregular shape.

[0058] The heat-absorbing material added to the light-transmitting container 20 can also be made into a columnar structure, a spherical structure or a cubic structure, and hollowed out inside the three-dimensional structure to form a hollow cavity 100 of various shapes, so that the raw materials to be atomized can be filled in the hollow cavity 100. The heat-absorbing material can absorb more heat to transfer it to the raw materials to be atomized. For example, in Figure 7, the heat-absorbing body 101 forms an annular and a circular groove, each groove is a hollow cavity 100, and the raw materials to be atomized are filled in the groove of the heat-absorbing body 101. The heat-absorbing body 101 can also form multiple annular grooves. The light-transmitting container 20 can be provided with a heat-absorbing material in a three-dimensional structure and a heat-absorbing material in a powdered form, so as to further improve the atomization degree of the raw materials to be atomized.

[0059] In one embodiment of the present application, Figure 8 is a schematic diagram of the structure of a heat-absorbing film on the inner surface of a light-transmitting container provided in this embodiment. Referring to Figure 8 , at least a portion of the heat-absorbing material constitutes heat-absorbing film 102, which covers a portion of the inner surface of light-transmitting container 20. In other words, the interior of light-transmitting container 20 can also be coated with the aforementioned materials that effectively absorb laser heat to promote atomization of the raw material to be atomized. Because the condition of the e-liquid needs to be monitored, this coating only requires half-coating.

[0060] The laser cigarette lighter device may include a powdered heat-absorbing material, a porous loose structure 103 formed of the heat-absorbing material, a heat-absorbing body 101 and a heat-absorbing film 102 , or may include one or any combination thereof.

[0061] In one embodiment of the present application, the laser cigarette lighter device further includes an antireflection film 105. As shown in FIG2 , the antireflection film 105 covers at least one portion of the outer surface and inner surface of the light-transmitting container 20. It is understood that a corresponding film can be applied to the surface of the light-transmitting container 20 according to the wavelength of the laser 30 to achieve a higher transmittance, thereby further improving the atomization degree of the raw material to be atomized.

[0062] In one embodiment of the present application, Figure 9 is a structural schematic diagram of another laser cigarette lighting device provided in an embodiment of the present application, and Figure 10 is a disassembled diagram of the structure shown in Figure 9.

[0063] The bottom of the laser 30 is supported by a thermally conductive insulating substrate 40. A metal layer with a certain pattern exists on the surface of the thermally conductive insulating substrate 40, which is electrically connected to the laser 30. Multiple lasers 30 can be mounted on the surface of the metal layer using solder such as silver paste, indium, gold-tin, tin-silver-copper, or tin-bismuth. The metal layer includes a positive electrode and a negative electrode, which are electrically connected to the positive and negative poles of the laser 30, respectively. The thermally conductive insulating substrate 40 can be a highly thermally conductive insulating substrate such as aluminum nitride, copper-diamond, beryllium oxide, or aluminum oxide to facilitate heat dissipation from the laser 30 and reduce the release of harmful substances from the metal layer on the surface of the thermally conductive insulating substrate 40. In addition, the material of the housing 10 can be set to heat dissipation metal. The heat dissipation metal of the housing 10 can be a highly thermally conductive metal such as copper and / or aluminum to further effectively dissipate heat from the laser 30.

[0064] The positive and negative electrodes of the laser 30 can be led out using a metal electrode rod 60 (as shown in Figures 9 and 10), or a flexible printed circuit board (FPCB) 50 can be used to lead out the positive and negative electrodes of the laser 30 (as shown in Figures 1 to 3). The metal electrode rod 60 or the flexible printed circuit board 50 is inserted into the printed circuit board (PCB) using surface mount technology (SMT) or other methods to electrically connect the laser 30 to the driving circuit. A circuit with certain functions is provided on the PCB to drive the laser 30. The driving conditions can be that the laser 30 is in continuous mode or quasi-continuous wave (QCW) mode, such as 1 second on, 10 seconds off, a pulse width ranging from 10ns to 1 second, a duty cycle ranging from 1% to 100%, and a peak power ranging from 1W to 500W. When there are a large number of lasers 30 , different holes or pads can be set on the PCB, and the metal electrode rods 60 or FPCB 50 used to lead out the electrodes of the lasers 30 can be evenly welded to the surface of the PCB to achieve uniform distribution of the lasers 30 .

[0065] The laser 30 in the laser emitting unit can be one or more of an edge-emitting laser, a vertical-cavity surface-emitting laser, a photonic crystal laser, and a horizontal-cavity surface-emitting laser.
