Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a planar ceramic atomization air intake structure for electronic cigarettes. Background Art

[0002] When airflow enters the oil cup of single-airway e-cigarettes currently on the market, it generally impacts the ceramic bottom directly at a 90-degree vertical angle, or impacts the side of the ceramic bottom at a small angle through an inclined surface. The airflow of existing airway intake methods on the market cannot adhere closely to the atomization plane, and cannot fully and timely carry the atomized particles out of the atomization chamber. Alternatively, the airflow of airway intake methods is dispersed, and the atomized particles cannot be carried out of the atomization chamber in a concentrated manner. All of these results in less rich smoke, a poor puffing experience, and a large amount of condensate, which affects the puffing experience. Condensate and e-liquid accumulate, and in severe cases, it can block the air inlet, resulting in changes in draw resistance or even no smoke. In response to the above common situations in the industry, this solution will optimize airflow and airway improvements. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The electronic cigarette has a flat ceramic atomization air intake structure. The air intake hole set on the side of the ceramic atomization core is 0-5mm higher than the atomization plane.

[0021] An atomizing plane 22 is provided on the top of the ceramic atomizing core 7, and its bottom is connected to the main part of the ceramic atomizing core 7. A side air inlet 20 is provided on the side of the ceramic atomizing core 7. A columnar bone position 21 is designed inside the plastic bracket 9. The ceramic atomizing core 7 is fixedly installed in the atomizing bin 14, and an atomizing core sealing silicone 6 is provided on the outside. The atomizing core sealing silicone 6 is sealed and connected to the bottom of the oil bin 16 of the plastic oil cup 5. The plastic bracket 9 is fixedly installed at the bottom of the atomizing bin 14 of the plastic oil cup 5, and an electrode column 13 is assembled inside it. The electrode column 13 is in contact with the bottom of the ceramic atomizing core 7.

[0022] Two silicone sealing rings 8 are sleeved on the outside of the plastic bracket 9. The silicone sealing rings 8 fit tightly against the inner wall of the plastic oil cup 5. A PCBA assembly is fixedly mounted on one side of the bottom of the plastic oil cup 5, on which a charging port 10 is provided. The charging port 10 passes through the plastic bottom cover 12 and extends to the outside. The bottom cover near the air hole 11 is opened at the bottom of the plastic oil cup 5, and the plastic bottom cover 12 is fixedly mounted on the bottom of the aluminum alloy shell 2.

[0023] The plastic nozzle 1 is fixedly connected to the top of the aluminum alloy shell 2, the battery core 4 is fixedly installed on the right side of the aluminum alloy shell 2, the smoke outlet 19 is opened inside the plastic nozzle 1, and the switch microphone 3 is fixedly installed on the left side of the aluminum alloy shell 2, located directly below the plastic nozzle 1, and its top is tightly fitted with the oil tank sealing silicone 17.

[0024] The plastic oil cup 5 is fixedly installed inside the aluminum alloy shell 2, located between the switch microphone 3 and the battery core 4. Its top is snap-fitted with the plastic suction nozzle 1. The oil tank 16 is opened on the upper side of the interior of the plastic oil cup 5.

The atomization bin 14 is opened on the lower side of the interior of the plastic oil cup 5 and is connected to the bottom of the oil tank 16.

[0025] The inner wall of the plastic bracket 9 is provided with an oil guide rib 25, and an oil reservoir 26 is located within the plastic bracket 9. This reservoir 26 and the oil guide rib 25 are connected by a micro-drainage channel with a diameter of 0.2-0.3mm. This channel directs and stores condensed liquid to prevent airway blockage. Regularly clean the condensed liquid in the oil reservoir 26 by disassembling the bottom to ensure long-term stable operation of the device.

[0026] The side air inlet 20 is 2-5mm higher than the ceramic atomization plane. The side air inlet 20 is circular in shape, which is conducive to concentrating the airflow to impact the ceramic atomization area. The side air inlet 20 is set parallel to or higher than the ceramic plane and on the side of the ceramic. The airflow enters the oil cup from the side to prevent the downward flowing condensation or smoke oil from blocking the side air inlet 20.

[0027] The plastic oil cup 5 is designed with a bevel or arc surface on the side where the ceramic atomizer core 7 is assembled. The bevel angle is between 5° and 60°, and the arc angle is between R1-R1000. The airflow is directly close to the ceramic atomizer surface, which can maximize the removal of the smoke medium on the ceramic atomizer surface, improve the ceramic atomization efficiency, enhance the puff taste, and reduce the generation of condensation.

[0028] The plastic bracket 9 is internally designed with columnar bones 21. The columnar bones 21 are cylindrical or strip-shaped, and the spacing gradually changes from 0.5mm on the side close to the atomization chamber 14 to 3mm on the side away from it. The columnar bones 21 can guide condensed liquid or e-liquid into the bracket oil tank 26 through the principle of capillary adsorption, preventing condensation or e-liquid from affecting the smoking experience.

[0029] Assembly steps: First, put the ceramic atomizer core 7 on the atomizer core sealing silicone 6, install it into the atomizer chamber 14 of the plastic oil cup 5, and make sure the atomization plane 22 is facing upward. Then install the electrode column 13 and the silicone sealing ring 8 on the plastic bracket 9, screw it into the atomizer chamber 14 from the bottom, tighten and seal it, then install the PCBA component and charging port 10, buckle the plastic bottom cover 12, and ensure that the air inlet hole 11 of the bottom cover is unobstructed. Then, embed the switch microphone 3 into the oil tank sealing silicone 17 and install it on the top of the oil cup. Buckle the plastic suction nozzle 1 so that the suction nozzle oil sealing column 18 is tightly fitted with the sealing silicone. Finally, put on the aluminum alloy shell 2 to complete the overall assembly. Example 2: Based on Example 1, a stepped guide groove 23 is provided at the position corresponding to the air inlet on the inner side of the plastic oil cup 5. A slope is provided at the position corresponding to the air inlet on the inner side of the plastic oil cup 5 with an angle of 5°-60° or an arc R angle of R1-R1000. The surface is processed with a stepped guide groove with a depth of 0.1-0.5mm and a width of 0.5-2mm to guide the airflow to flow close to the atomizing plane 22.

[0030] The surface of the columnar bone position 21 is coated with a hydrophilic nanocoating, which is composed of a polymer of silicon dioxide (SiO2) nanoparticles, hydroxyapatite, and graphene oxide. The hydrophilic nanocoating is attached to the surface of the columnar bone position 21 by spraying, dipping, etc., and utilizes nano-level surface roughness and hydrophilic groups to improve the hydrophilicity and adsorption performance of the columnar bone position 21. Example 3: Please refer to Figure 7 On the basis of the first embodiment, the side air inlet 20 is a contraction-type air passage, which is designed as a contraction structure with an inlet diameter of 2-3 mm and an outlet diameter of 1-1.5 mm, accelerating the air flow rate and enhancing the carrying capacity of atomized particles; an air flow sensor 24 is fixedly installed in the atomization chamber 14, an electromagnetic micro valve is provided at the side air inlet 20, and a spare air inlet 27 is reserved in the plastic bottom cover 12. When the sensor detects blockage, the side air inlet 20 is automatically closed and the spare air inlet 27 is opened to ensure stable suction resistance.

[0031] The inner side of the side air inlet 20 is covered with an ultra-thin elastic silicone membrane, and a cross-shaped micro-slit is opened on the membrane to match the shape of the air inlet. The slit width is 0.1-0.2mm. When air flows through, the micro-slit opens under the action of air pressure, allowing air to enter. When you stop inhaling, the micro-slit automatically closes to prevent condensation or smoke oil from flowing back.

[0032] An airflow recoil channel 28 is added inside the curved surface of the plastic oil cup 5. One end of the airflow recoil channel 28 is connected to the upper part of the atomization chamber 14, and the other end is tangent to the outer side of the side air inlet 20. The channel diameter is 0.5-0.8mm. When the user stops inhaling, the residual air pressure in the atomization chamber 14 will push a small amount of air out through the recoil channel 28 quickly, blowing back the surface of the side air inlet 20 to remove attached tiny droplets or e-liquid particles.

[0033] Working Principle: When the user holds the plastic mouthpiece 1 and draws, the switch microphone 3 senses the change in air pressure, triggering the PCBA assembly to start the circuit. The battery cell 4 supplies power to the ceramic atomizer core 7 through the electrode column 13, causing the atomizer plane 22 to heat up, atomizing the e-liquid in the oil tank 16 into smoke. Outside air enters through the bottom cover air inlet 11 and flows into the atomizer chamber 14 through the side air inlet 20. Guided by the stepped guide groove 23, it flows close to the atomizer plane 22, efficiently carrying the smoke through the main air duct 15 of the oil cup and the smoke outlet 19 of the mouthpiece into the oral cavity. The condensate generated during the atomization process is absorbed by the columnar bone part 21 and directed into the oil storage tank through the oil guide bone part and micro-drainage channel to avoid entering the airway. The airflow sensor 24 monitors the flow rate in real time. The PCBA assembly dynamically adjusts the power of the ceramic atomizer core 7 according to the flow rate to ensure stable smoke volume. If blockage is detected, it automatically switches to the backup air inlet to maintain normal inhalation.
