Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

The first embodiment is as follows:

a heating core for an electronic cigarette is shown in figures 1, 2, 3 and 4 and comprises a heating body 1, a cotton core layer 2, a stainless steel outer shell 3 and a base 4. The base 4 is made of plastic. The cotton core layer 2 is used for guiding oil, and the oil can reach the position of the heating body 1 through the cotton core layer 2. The heating body 1 is made of ceramic materials, the cotton core layer 2 is coated outside the heating body 1, a first through groove 31 and an open groove 32 are formed in the side wall of the stainless steel shell, the stainless steel shell is sleeved with the cotton core layer 2 through the open groove 32, part of the cotton core layer 2 is left in the outer side of the stainless steel shell, and the bottom of the stainless steel shell is sleeved and fixed on the base 4.

During assembly, the cotton core layer 2 surrounds the heating body 1 and is embedded into the stainless steel sleeve, and the heating body is directly inserted into the stainless steel sleeve through the open slot 32 during embedding, so that the assembly mode is simple and quick. The heating body 1 adopts ceramic materials for heating, so that the support strength is high, and a built-in stainless steel pipe is not needed. Meanwhile, the ceramic has micropores, so that the atomization effect is realized when the ceramic generates heat.

The heating element 1 has a conductive pin 5. The base 4 is provided with two channels 41, the heating element 1 is electrically connected with two pins 5, and the two pins 5 respectively penetrate through the two channels 41. This allows the external circuit to supply power to the heating element 1, thereby realizing heating.

In order to increase the contact area, the heating element 1 is provided in a hollow columnar structure, and a plurality of second through grooves 11 are provided in the side surface of the heating element 1. Thus, the contact area between the heating body 1 and the cotton core layer 2 is increased, which is beneficial to uniformly heating the cotton core layer 2. The oil is continuously absorbed by the cotton core layer 2. The first through groove 31 and the second through groove 11 are located opposite to each other. Can ventilate inside and outside when can realizing the atomization effect like this, the gas permeability is better.

In order to improve the service life, the pin 5 and the channel 41 are fixed by filling insulating glue. This makes it difficult to break the pin 5 at the time of assembly. The bottom of the base 4 is provided with a ring groove 42, and the channel 41 is positioned in the ring groove 42. This arrangement facilitates insertion of the pin 5 into the channel 41. As shown in fig. 4, the channel 41 is inclined and has a guiding function, so that the pin 5 is bent to facilitate the glue fixation.

Example two:

the difference from the first embodiment is that the channel 41 is arranged vertically, as shown in fig. 5, so that the assembly of the pin 5 is easier.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
