[0029] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0030] refer to Figure 1 The diagram shows the exploded structure of a laser-heated atomizing electronic cigarette. The laser head 4 works in conjunction with the ceramic atomizing core 2 to atomize the e-liquid, avoiding the carbon buildup caused by the chemical reaction between the traditional resistance wire and the e-liquid.

[0031] refer to Figures 1 to 4A laser-heated atomizing electronic cigarette includes an oil cup 1, a ceramic atomizing core 2, a mounting base 3, and a laser head 4. The ceramic atomizing core 2 is mounted on the oil cup 1 via a support 5. The support 5 has a first oil inlet 51 communicating with the oil cavity 11 of the oil cup 1, and the first oil inlet 51 extends to the ceramic atomizing core 2. The mounting base 3 is fixed to one side of the oil cup 1, and an atomizing cavity 91 is formed between the mounting base 3 and the support 5. An atomizing surface 21 is provided on the side of the ceramic atomizing core 2 near the atomizing cavity 91. The laser head 4 is mounted on the side of the mounting base 3 away from the atomizing cavity 91 and is positioned towards the ceramic atomizing core 2. An isolation lens 31 is provided between the mounting base 3 and the atomizing cavity 91. The laser emitted by the laser head 4 passes through the isolation lens 31 and irradiates the atomizing surface 21 of the ceramic atomizing core 2.

[0032] The laser-heated atomizing electronic cigarette of this application heats the ceramic atomizing core 2 using a laser, enabling the ceramic atomizing core 2 to be heated quickly and evenly. The ceramic atomizing core 2 will not discolor or accumulate carbon, ensuring a consistent taste. The isolation lens 31 separates the atomizing chamber 91 from the laser head 4 to protect the laser head 4 and prevent the laser head 4 from contacting the condensed e-liquid droplets after atomization, ensuring that the laser head 4 can work stably.

[0033] In order to better atomize the e-liquid, in this embodiment, the ceramic atomizing core 2 is a multi-microporous black ceramic atomizing core 2 without a metal heating element, and the pore diameter of the micropores inside the ceramic atomizing core 2 is 0.1um-0.2mm.

[0034] Understandably, with this design, the ceramic atomizing core 2 is a high-temperature resistant, multi-microporous black ceramic atomizing core 2. The e-liquid in the vapor chamber permeates into the micropores inside the ceramic atomizing core 2. The black ceramic material can effectively absorb the laser, improving heating efficiency. The heat released by the laser heats the ceramic atomizing core 2 and the e-liquid in the internal micropores. After heating, the e-liquid is atomized and diffused into the atomization chamber 91. The ceramic atomizing core 2 does not contain any metal heating elements, which refer to resistance heating wires or heating plates. This ensures that the ceramic atomizing core 2 will not chemically react with the e-liquid during the laser heating process. This makes it less prone to carbon buildup and discoloration during the atomization process, ensuring that the atomized ceramic core does not discolor or accumulate carbon, maintaining a consistent flavor.

[0035] To ensure the heating effect of the laser, in this embodiment, reference is made to... Figure 2 and Figure 3 The distance between the laser head 4 and the ceramic atomizing core 2 is less than 30mm.

[0036] Understandably, with this setup, the power of the laser head 4 is between 5W and 15W, preferably 5W. Given the limited power, the distance between the laser head 4 and the ceramic atomizing core 2 cannot be too long to prevent the laser from failing to penetrate the smoke formed by atomization within the atomization cavity 91, thus ensuring that the laser can effectively irradiate the atomization surface 21 of the ceramic atomizing core 2 and guarantee heating efficiency.

[0037] To ensure that the e-liquid can penetrate into the ceramic atomizing core 2, in this embodiment, reference is made to... Figure 3 A sealing silicone 6 is provided between the oil cup 1 and the support 5. An oil cavity 11 is formed between the sealing silicone 6 and the inner wall of the oil cup 1. The sealing silicone 6 is provided with a second oil inlet 61 that connects the oil cavity 11 and the first oil inlet 51. The support 5 is provided with a fixing groove 52 for installing the ceramic atomizing core 2. A sealing silicone 7 is provided between the ceramic atomizing core 2 and the fixing groove 52. The sealing silicone 7 is provided with a third oil inlet 71 that connects the first oil inlet 51 and the ceramic atomizing core 2.

[0038] Understandably, with this setup, the gap between the oil cup 1 and the support 5 is sealed by the sealing silicone 6, and the gap between the support 5 and the ceramic atomizing core 2 is sealed by the sealing silicone 7 to prevent e-liquid leakage. The oil chamber 11, the second oil inlet 61, the first oil inlet 51 and the third oil inlet 71 are connected in sequence and extend to the ceramic atomizing core 2, which can effectively guide the e-liquid in the oil chamber 11 to be delivered to the ceramic atomizing core 2.

[0039] To optimize the oil inlet path and smoke path, in this embodiment, reference is made to... Figures 1 to 3 The support 5 is provided with two first oil inlet holes 51 arranged in a V-shape. The support 5 is provided with a mixing chamber 94 between the two first oil inlet holes 51. The mixing chamber 94 is not connected to the first oil inlet holes 51. The mixing chamber 94 is connected to the nozzle 96 on the outer wall of the oil cup 1 through the air passage 95. The mixing chamber 94 is connected to the atomizing chamber 91 through multiple air distribution passages.

[0040] Understandably, with the two first oil inlets 51 arranged in a V-shape, located on both sides of the air passage 95 and the mixing chamber 94, the oil inlet path and the smoke path will not interfere with each other, allowing the smoke to be better mixed and delivered to the mouthpiece 96. The V-shaped arrangement of the two first oil inlets 51 can ensure sufficient oil intake, while also evenly delivering the e-liquid to the ceramic atomizing core 2.

[0041] To ensure thorough mixing of the smoke, in this embodiment, reference is made... Figure 2 The air distribution path includes a first air path 92 and a second air path 93 that are connected in sequence. The first air path 92 passes through the support 5 along the thickness direction, and the second air path 93 is located between the support 5 and the sealing silicone 6. The first air path 92 and the second air path 93 are perpendicular to each other.

[0042] Understandably, with this setup, the first air passage 92 and the second air passage 93 are perpendicular to each other. The smoke from the atomizing chamber 91 is split into two airflows through the two first air passages 92, and each first air passage 92 is split into two second air passages 93. The four second air passages are then split into four airflows. These four airflows converge in the mixing chamber 94 and counteract each other to create turbulence, ensuring that the smoke is mixed evenly in the mixing chamber 94 and maintaining the taste. The mixed smoke is then inhaled by the user through the mouthpiece 96.

[0043] It should be further explained that an O-ring 12 is provided between the oil cup 1 and the mounting base 3. The O-ring 12 seals the gap between the oil cup 1 and the mounting base 3, ensuring that the condensed e-liquid will not leak to the outside.

[0044] To prevent the laser from irradiating the suction nozzle 96, in this embodiment, reference is made... Figure 2 and Figure 3 The nozzle 96, ceramic atomizing core 2, and laser head 4 are arranged along the same straight line. The support 5 has a light-blocking part 53 between the ceramic atomizing core 2 and the nozzle 96. The laser emitted by the laser head 4 cannot reach the nozzle 96 due to the blocking effect of the light-blocking part 53.

[0045] Understandably, this setup, with the mouthpiece 96, ceramic atomizing core 2, and laser head 4 aligned in a straight line, ensures that the laser accurately illuminates the ceramic atomizing core 2. It also better adapts to the elongated structure of the electronic cigarette. The light-blocking part 53 of the support 5 can prevent the laser from shining on the mouthpiece 96, thus avoiding laser exposure to the user and ensuring safety.

[0046] In order to install the laser head 4, in this embodiment, refer to Figures 1 to 4 The laser head 4 is fixed on the mounting base 3 by the mounting plate 41. The mounting base 3 is provided with a mounting groove 32 at the corresponding position of the laser head 4. The laser head 4 is placed in the mounting groove 32. An isolation lens 31 is provided between the mounting groove 32 and the atomizing cavity 91.

[0047] Understandably, with this setup, the mounting plate 41 is a circuit board, the laser head 4 is fixed to the mounting base 3 via the mounting plate 41, the mounting groove 32 positions the laser head 4, and the isolation lens 31 protects the laser head 4 without affecting the laser irradiation.

[0048] To ensure the protective effect of the isolation lens 31 on the laser head 4, in this embodiment, reference is made to... Figure 4 The isolation lens 31 is integrally formed on the mounting base 3.

[0049] Understandably, with this setup, the isolation lens 31 can prevent the e-liquid droplets formed by smoke condensation from directly contacting the laser head 4. The mounting base 3 is made of PC material, and the isolation lens 31 and the mounting base 3 are integrally injection molded, which can ensure that there are no gaps between the isolation lens 31 and the mounting base 3 that would allow e-liquid droplets to seep into the laser head 4, while also simplifying the assembly process.

[0050] In order to power the laser head 4, in this embodiment, refer to Figures 1 to 3 The mounting base 3 is fixed to a base 8 at the end away from the oil cup 1. The base 8 contains a battery 81 that is electrically connected to the laser head 4.

[0051] Understandably, with this setup, the mounting plate 41 is a circuit board, and the battery 81 is electrically connected to the laser head 4 through the circuit board, thereby powering the laser head 4. The voltage of the battery 81 is 3.7V or 7.4V, which can stably power the 5W laser head 4.

[0052] In this embodiment, the battery 81 powers the laser head 4. The e-liquid in the oil chamber 11 continuously permeates into the micropores of the ceramic atomizing core 2. When the user inhales through the mouthpiece 96, the pressure sensor, such as the microphone, detects the pressure change inside the electronic cigarette, thereby activating the laser head 4. The laser emitted by the laser head 4 passes through the isolation lens 31 and irradiates the atomization surface 21 of the ceramic atomizing core 2, causing the ceramic atomizing core 2 to be rapidly heated by the laser, thereby atomizing the e-liquid inside the ceramic atomizing core 2 into an aerosol. The airflow carries the smoke in the atomization chamber 91 to the mixing chamber 94 for mixing. The mixed smoke is then delivered to the mouthpiece 96 through the air passage 95 for the user to inhale.

[0053] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
