Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a novel heating element and its cartridge. Background Technology

[0002] Electronic cigarettes, as alternatives to traditional cigarettes, are often used for smoking cessation. They have a similar appearance and taste to cigarettes, but generally do not contain tar, particulate matter, or other harmful components found in cigarettes. Related technologies for electronic cigarettes include an electronic cigarette casing, an atomizing component, a power supply component, and a liquid reservoir housed within the casing.

[0003] Existing replaceable e-cigarette cartridges typically include a heating element. The ceramic heating element within this element heats and evaporates the e-liquid. Therefore, the space between the heating element and the ceramic heating element is an airflow channel, which often leads to e-liquid leakage in current e-cigarette cartridges. Thus, there is an urgent need to develop a new type of heating element and cartridge to meet practical usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a novel heating element and its cartridge to solve the problem of oil leakage in existing electronic cigarette cartridges.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The ceramic heating element has a hollow structure. The outer cover is fitted onto the surface of the base shell. The bottom end of the ceramic heating element passes through the outer cover and is electrically connected to the electrodes. A ventilation hole is also provided on the top surface of the base shell. A conductive channel is provided between the ventilation hole and the ceramic heating element. A removable leak-proof component is provided inside the ventilation hole. The leak-proof component has a hollow frustum-shaped structure. The two ends of the leak-proof component are an air inlet and an air outlet, respectively. The air outlet of the leak-proof component extends to one side of the conductive channel.

[0007] As a further solution described above, the inner wall of the ventilation hole is provided with a groove, which is a ring structure. The leak-proof component has a rubber ring at one end near the air inlet. The leak-proof component is fixedly connected to the inside of the ventilation hole through the rubber ring, and the rubber ring and the groove are fitted together.

[0008] In the above description, as a further embodiment, the top of the ceramic heating element is the e-liquid contact part, the bottom of the ceramic heating element is the electrode connection part, the limiting cover is embedded in the e-liquid contact part, and the electrode connection part extends into the bottom shell and is electrically connected to the electrode.

[0009] As a further embodiment of the above description, the top of the outer cover is provided with a downwardly recessed inlay notch, and a positioning hole is opened at the bottom of the inlay notch. The positioning hole passes through the space between the outer cover and the bottom shell. The e-liquid contact part of the ceramic heating element is inlaid in the inlay notch, and the electrode connection part of the ceramic heating element is inserted into the positioning hole.

[0010] A cigarette holder includes a shell and a novel heating element as described above. The bottom of the shell is hollow, and the electronic cigarette heating element is embedded in the bottom of the shell to form a storage cavity. A extraction tube is provided at the top of the shell into the storage cavity, and the bottom end of the extraction tube extends into the interior of the ceramic heating element.

[0011] As a further embodiment, the inner wall of the shell is provided with a gasket and a permeation plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the leak-proof component with a hollow frustum-shaped structure inside the ventilation hole of the bottom shell, the size of the air inlet is reduced, which can prevent viscous oil from flowing out from the air inlet.

The electrode 4 is embedded in the bottom of the base shell 1. The ceramic heating element 3 has a hollow structure. The outer cover 2 is fitted onto the surface of the base shell 1. The bottom end of the ceramic heating element 3 passes through the outer cover 2 and is electrically connected to the electrode 4. A ventilation hole 13 is also provided on the top surface of the base shell 1. A conductive channel 11 is provided between the ventilation hole 13 and the ceramic heating element 3. A detachable leak-proof component 5 is provided inside the ventilation hole 13. The leak-proof component 5 has a hollow frustum-shaped structure. The two ends of the leak-proof component 5 are an air inlet 51 and an air outlet 52, respectively. The air outlet 52 of the leak-proof component 5 extends to one side of the conductive channel 11.

[0021] The leak-proof component 5, which has a hollow frustum-shaped structure, is installed inside the ventilation hole 13 of the bottom shell 1, reducing the size of the air inlet 51 and preventing viscous oil from flowing out of the air inlet 51. At the same time, the leak-proof component 5, through the rubber ring part 53 at one end of the air inlet 51, cooperates with the snap groove 12 in the ventilation hole 13, improving the sealing between the leak-proof component 5 and the bottom shell 1, further reducing the possibility of oil leakage. Meanwhile, the hollow frustum structure of the leak-proof component 5 ensures air circulation during the user's inhalation process.

[0022] Specifically, such as Figure 3-4 As shown, the inner wall of the ventilation hole 13 is provided with a groove 12, which is a ring structure. The leak-proof part 5 is provided with a rubber ring part 53 at one end near the air inlet 51. The leak-proof part 5 is fixedly connected to the inside of the ventilation hole 13 through the rubber ring part 53, and the rubber ring part 53 and the groove 12 are fitted together.

[0023] Specifically, such as Figure 2 and Figure 5As shown, the top of the ceramic heating element 3 is the e-liquid contact part 31, and the bottom of the ceramic heating element 3 is the electrode 4 connection part 32. The limiting cover is embedded in the e-liquid contact part 31. The electrode 4 connection part 32 extends into the bottom shell 1 and is electrically connected to the electrode 4. The top of the outer cover 2 is provided with a downward recessed inlay notch 21. A positioning hole 22 is opened at the bottom of the inlay notch 21.

The e-liquid contact part 31 of the ceramic heating element 3 is embedded in the inlay notch 21, and the electrode 4 connection part 32 of the ceramic heating element 3 is inserted into the positioning hole 22.

[0024] A cigarette holder includes a shell 6 and a novel heating element as described above.
