The ceramic core heating wire combines the advantages of ceramic and heating wire. The ceramic material has excellent high-temperature resistance, good insulation and stability, and the heating wire can convert electric energy into heat energy. The heating wire is embedded in the ceramic core, and the heat generated by the heating wire is evenly emitted through the ceramic material, so that the atomization effect is better.

[0017] Further, the ceramic core body is a planar ceramic.

[0018] Preferably, the ceramic core body used in the utility model is a planar ceramic, and the planar ceramic core has a larger heat dissipation area. This means that under the same heating power, the planar ceramic core can more effectively dissipate heat to the surrounding environment, thereby improving the heat dissipation efficiency. In addition, the larger contact area of the planar ceramic core also makes the connection with other components more tight and stable, which is conducive to improving the overall heat conduction performance.

[0029] Embodiment 1

[0030] The present embodiment provides a structure for preventing cracking of the ceramic core heating wire of an electronic cigarette, the electronic cigarette comprising an electronic cigarette body 1, a battery support 2, a ceramic core heating wire 4, an oil cup 5, an air outlet sealing silica gel 6, a suction nozzle 7 and other structural components arranged in the electronic cigarette body 1; the air outlet sealing silica gel 6 is arranged below the suction nozzle 7 to avoid smoke leakage; the oil cup is arranged below the air outlet sealing silica gel 6, the battery support 2 is provided with an air inlet column 8, the top outlet of the air inlet column 8 is flush with the end face of the battery support 2, the air inlet column 8 communicates with the air inlet below, after the air current is introduced into the oil cup by the air inlet column 8, the air current moves horizontally first, passes through the ceramic core heating wire 4, and then moves upward and finally flows out of the suction nozzle 7.

[0031] In combination Figures 2-3As shown, the electronic cigarette ceramic core heating wire 4 includes a ceramic core body 41, a heating wire 42, an electrode 43 and a ceramic sealing silica gel 44; the electrode 43 is arranged at both ends of the heating wire 42, the connecting point of the electrode 43 and the heating wire 42 extends out of the ceramic core body 41, and the distance of the connecting point extending out of the ceramic core body 41 is 0.5-1mm. In the utility model, the two electrodes 43 are respectively located on the oblique diagonal extension lines of the two sides of the ceramic core body 41. The oblique angle distribution is adopted, the spatial symmetry is better, and the electrode 3 is heated more uniformly after being transmitted to the electrode 43.

[0032] Since the lower part of the ceramic core body 41 is an airway, and the airflow direction is parallel to the plane where the heating wire is located, that is, the horizontal direction flows, the electrodes 43 of the products on the market are generally distributed in the middle of the airway, which affects the airflow and easily produces condensate, thereby affecting the taste. After the pin of the connecting electrode 43 extends to the outside of the ceramic core body 41, the electrode 43 can reduce the shielding of the airway, the electrode 43 is distributed on the oblique angle of the two sides of the ceramic, avoids the airway, can make the aerosol pass smoothly, reduce the production of condensate, and avoid the phenomenon of hole blockage.

[0033] In combination Figures 4-5 As shown, the ceramic core body 41 is embedded into the bottom of the ceramic sealing silica gel 44; and the connecting point is located on both sides of the bottom of the ceramic sealing silica gel 44. The ceramic core body 41 is embedded into the ceramic sealing silica gel 44, and since the ceramic sealing silica gel 44 is a flexible structure, it can play a certain buffering role and better protect the ceramic core body 41. In combination with another invention point of the utility model, the electrode 43 is extended to the lower part of the ceramic sealing silica gel 44, so that the electrode 43 has the ceramic sealing silica gel 44 as a buffer in the stress direction, and the ceramic heating wire 42 can be more stably contacted with the electrode 3.

[0034] In the utility model, the electrode 43 of the electronic cigarette ceramic core heating wire 4 is used for connection and conduction. The electrode 43 is connected with the battery to form a conduction path, ensures that the current can be smoothly transmitted to the heating wire 42, thereby causing the heating wire 42 to generate heat, and atomizes the tobacco tar. In the utility model, the pin of the heating wire 42 is extended to both ends of the ceramic core body 41, so that the pin extends to the outside of the ceramic core body 41, so that the electrode 43 does not directly contact the ceramic core body 41 in the stress direction, avoids the top of the ceramic core body 41 from being cracked, improves the service life of the product, and reduces the product failure.

[0035] The ceramic core body 41 is a planar ceramic, unlike the columnar ceramic core body 41 in the prior art, which extends the pin to meet different line length connection conduction, while the ceramic core body 41 adopted by the utility model is a planar ceramic, and the planar ceramic core has a larger heat dissipation area. This means that under the same heating power, the planar ceramic core can more effectively dissipate heat to the surrounding environment, thereby improving the heat dissipation efficiency. In addition, the larger contact area of the planar ceramic core also makes the connection with other components more compact and stable, which is beneficial to improve the overall heat conduction performance. And the planar ceramic core extension pin first guarantees the basic function of contact conduction, and the extension can improve the crushing of the ceramic core body 41 under stress, and the extension of the ceramic core body 41 end face to the ceramic sealing silica gel 44 has elasticity, which satisfies the contact and improves the crushing problem. In addition, the design scheme of the utility model can improve the airflow affected by the electrode 3, and the entire air duct is not blocked, and the airflow is smooth.
