When the cartridge is in a smoking state, the tobacco rod needle is inserted into the cartridge needle to electrically connect the power component and the heating component, and at the same time, the magnet on the tobacco rod provides a certain adsorption force to the tobacco rod needle, preventing the cartridge needle from being separated from the tobacco rod needle and affecting the normal operation of the cartridge. An electronic cigarette with such a structure has the following disadvantages. Since it is simply adsorbed to the cartridge needle by the magnet, the abutment force between the cartridge needle and the tobacco rod needle is limited, which makes it easy for the cartridge needle to fall off from the tobacco rod needle, and makes the connection between the cartridge needle and the tobacco rod needle uncertain. Additionally, in order to maintain sufficient magnetic attraction of the magnet to the cartridge needle, the cartridge needle must be designed to be large, which increases the cost of the cartridge.

This invention provides an electronic cigarette that has a reliable connection between the cartridge and the tobacco rod and is low in manufacturing cost.

The present invention provides an electronic cigarette including a cartridge and a tobacco rod, one end of the tobacco rod is provided with a mounting groove configured to accommodate the cartridge, a magnet and a tobacco rod needle are provided at the bottom of the mounting groove, one end of the tobacco rod needle passes through the magnet and protrudes from the upper end surface of the magnet, the cartridge has a first end and a second end opposite to each other, the first end has a suction port, the second end is provided with a cartridge needle and a magnetic attraction cover, the magnetic attraction cover can be attracted to the magnet, the magnetic attraction cover is provided to cover the outer surface of the second end, one end of the cartridge needle is electrically connected to a heat generating component in the cartridge, and the other end is exposed to the outside of the magnetic attraction cover, the tobacco rod needle is electrically connected to a power supply component in the tobacco rod, and when the cartridge is in a smoking state, the magnet is provided to attract the magnetic attraction cover, bringing the cartridge needle and the tobacco rod into close contact.

FIG. 3 is an enlarged view of part A in FIG. 2 .

Next, the technical aspects of the embodiment of the present invention will be described with reference to the drawings, but the described embodiment is only a part of the embodiment of the present invention.

In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense. For example, they may be fixedly connected, detachably connected, or integrated, mechanically connected, electrically connected, directly connected, indirectly connected via an intermediate medium, or in communication within two elements or in a relationship of interaction between two elements. A person skilled in the art can understand the meaning of the above terms in the present invention according to the specific situation.

In this invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include direct contact between the first feature and the second feature, or may include contact between the first feature and the second feature without direct contact and with another feature therebetween. Furthermore, a first feature being "on top," "above," and "on the top surface" of a second feature may include the first feature being directly above and diagonally above the second feature, or may simply indicate that the horizontal height of the first feature is higher than that of the second feature. A first feature being "below," "below," and "on the bottom surface" of a second feature may include the first feature being directly below and diagonally below the second feature, or may simply indicate that the horizontal height of the first feature is lower than that of the second feature.

As shown in Figures 1 to 3, the present invention provides an electronic cigarette which includes a cartridge 1 and a tobacco rod 2, one end of the tobacco rod 2 is provided with a mounting groove 21 for accommodating the cartridge 1, a magnet 22 and a tobacco rod needle 23 are provided at the bottom of the mounting groove 21, and one end of the tobacco rod needle 23 passes through the magnet 22 and protrudes from the upper end surface of the magnet 22. The cartridge 1 has a first end and a second end opposite to each other, the first end has an intake port 11, the second end is provided with a cartridge needle 13 and a magnetic attraction cover 12, the magnetic attraction cover 12 can be attracted to a magnet 22, the magnetic attraction cover 12 is arranged to cover the outer surface of the second end, one end of the cartridge needle 13 is electrically connected to a heat generating component 14 in the cartridge 1, and the other end is exposed to the outside of the magnetic attraction cover 12, the tobacco rod needle 23 is electrically connected to a power supply component in the tobacco rod 2, when the cartridge 1 is in a smoking state, the magnet 22 attracts the magnetic attraction cover 12 and brings the cartridge needle 13 into close contact with the tobacco rod 2. The magnet 22 is ring-mounted on the outside of the tobacco rod needle 23, and one end of the cartridge needle 13 exposed to the magnetic attraction cover 12 is recessed with an insertion groove into which the tobacco rod needle 23 is inserted, and when the cartridge 1 is in a smoking state, one end of the tobacco rod needle 23 is inserted into the insertion groove of the cartridge needle 13, and the heating component 14 is electrically connected to the power supply component through the tobacco rod needle 23 and the cartridge needle 13, and the heating component 14 is heated by the power supply component. In this embodiment, the magnet 22 at the bottom of the mounting groove 21 attracts the magnetic attraction cover 12 of the cartridge 1, so that the second end of the cartridge 1 can be easily inserted into the tobacco rod 2 and prevented from falling out of the mounting groove 21 of the cartridge 1, and when the cartridge 1 is in a smoking state, the mutual attraction between the magnet 22 and the magnetic attraction cover 12 brings the cartridge needle 13 and the tobacco rod needle 23 into close contact with each other, ensuring the reliability of the electrical connection between the cartridge needle 13 and the tobacco rod needle 23. In addition, since the magnet 22 can be attracted to the magnetic attraction cover 12 of the cartridge 1, the attraction force between the magnet 22 and the magnetic attraction cover 12 can be directly relied upon to provide sufficient contact force to the cartridge needle 13 and the tobacco rod needle 23, and the cartridge needle 13 does not need to be made of a magnetic material, reducing the manufacturing cost of the cartridge needle 13, or even when the overall dimensions of the cartridge needle 13 are designed to be small, sufficient contact force can be provided between the cartridge needle 13 and the tobacco rod needle 23, ensuring the reliability of the electrical connection between the two. The electronic cigarette of the present invention has the characteristics of a reliable connection between the cartridge 1 and the tobacco rod 2 and low manufacturing costs.

Preferably, the cartridge needle 13 is made of a magnetic material, and the cartridge needle 13 can be made to have conductive properties and then attracted to the magnet 22. When the cartridge needle 13 is made of such a material, when the cartridge needle 13 is inserted into a predetermined position with the tobacco rod needle 23, the magnet 22 on the tobacco rod 2 can simultaneously attract the magnetic attraction cover 12 and the cartridge needle 13, thereby increasing the attraction force between the tobacco rod 2 and the cartridge 1. Alternatively, when the cartridge needle 13 is made of a non-magnetic material, the cartridge needle 13 only has conductive properties, and when the cartridge needle 13 is inserted into a predetermined position with the tobacco rod needle 23, the magnet 22 on the tobacco rod 2 only attracts the magnetic attraction cover 12 on the cartridge 1. This design can also realize the reliability of the connection between the cartridge 1 and the tobacco rod 2.
