In an optional embodiment, the base 10 is made of silicone. Further, the base 10 is provided with a through hole 101 penetrating from the first end face a to the second end face b, and accommodating grooves 102 recessed from the second end face b towards the first end face a. It should be noted that in the embodiment, the through hole 101 is for wiring and ventilation, and the accommodating grooves 102 are used for containing each of the terminals 20 so that the atomizer A is electrically connected with the electronic cigarette stem B through each of the terminals 20.
Specifically, FIG. 9 is a structural diagram of a terminal according to embodiments of the present disclosure; as shown in FIG. 9 , each of the terminals 20 is pressed and arranged in the accommodating grooves 102, and each of the terminals 20 comprises a fixing portion 201 and a clamping portion 202 extended from one end of the fixing portion 201. It should be noted that each of the terminals 20 is made of copper or other material having good conductivity. In an embodiment, the accommodating groove 102 is provided as a circular groove, and the fixing portion 201 is correspondingly provided as a cylindrical shape. When the atomizer A is connected with the electronic cigarette stem B, the power supply terminal B1 of the electronic cigarette stem B extends into the fixing portion 201, that is, into the accommodating groove 102. Further, the clamping portion 202 is recessed from an end towards the fixing portion 201 to form clamping grooves 203. In an optional embodiment, the clamping groove 203 is partially located on the fixed portion 201. It should be noted that the number and position of the clamping groove 203 can be set as required. In the embodiment, there are four clamping grooves 203 uniformly distributed on the clamping portion 202, and the two adjacent clamping grooves 203 are separated by a certain distance. The clamping grooves 203 enable the fixing portion 201 to be attached to an outer side of the power supply terminal B1 through elastic deformation when the power supply terminal B1 is assembled and connected to each of the terminals 20. Furthermore, the arrangement of a plurality of clamping grooves 203 is helpful for the user to quickly clamp and fix each of the terminals 20 during assembly, so as to realize quick assembly; when one of the clamping grooves 203 is damaged or deformed excessively after assembly or disassembly, there are other clamping grooves 203 to ensure the effective connection.
Further, FIG. 10 is a structural diagram of the atomizing core 30 according to embodiments of the present disclosure; as shown in FIG. 10 , the atomizing core 30 is provided with pins 301. In an optional embodiment, the atomizing core 30 is of ceramic, cotton or steel mesh which can realize the heating function. The atomizing core 30 is connected with the power supply terminal B1 of the electronic cigarette stem B through each of the pins 301, so that the tar can be atomized by heating. Optionally, each of the pins 301 is made of copper or other material having good conductivity. In an embodiment, each of the pins 301 comprises a main body portion 3011, a steering portion 3012 and a connecting portion 3013. The main body portion 3011 passes through the through hole 101, and the steering portion 3012 extends from the main body portion 3011 toward the accommodating groove 102, and the connecting portion 3013 extends into the accommodating groove 102 from the steering portion 3012. The pin 301 is bent by the steering portion 3012, so that the connecting portion 3013 can be arranged at a suitable position according to actual needs to be connected to each of the terminals 20, that is, to the power supply terminal B1 of the electronic cigarette stem B.
In the embodiment, the connecting portion 3013 passes through the clamping groove 203 and is fixed between the fixing portion 201 and the accommodating groove 102. In an embodiment, a gap 204 penetrating the fixing portion 201 is formed at the bottom of one of the clamping grooves 203 in a direction away from the clamping portion 202, and the length of the gap 204 is less than or equal to the depth of the clamping groove 203. The gap 204 enables each of the terminals 20 to be elastically deformed and the length of the gap 204 affects the state of the elastic deformation of each of the terminals 20. When the length of the gap 204 is less than or equal to the depth of the clamping groove 203, it is convenient for each of the terminals 20 to cling to an inner wall of the accommodating groove 102 after being inserted into the accommodating groove 102, and it is possible to ensure that the connecting portion 3013 is pressed tightly by each of the terminals 20, thereby preventing the electronic cigarette from being unusable due to each of the pins 301 falling off. In this way, the atomizing core 30 can be firmly and electrically connected with each of the terminals 20. Therefore, each of the terminals 20 presses each of the pins 301, thereby eliminating the welding process, saving manpower, facilitating the realization of automation and improving the process efficiency.
It should be noted that the atomizing core 30 of the embodiment has two pins 301, and so there are also two accommodating grooves 102 and two terminals 20. It should be further noted that when each of the terminals 20 is fitted into the accommodating groove 102, a clamping groove 203 is set toward the through hole 101 so as to arrange each of the pins 301.
In an embodiment, the base 10 is recessed from the second end face b towards the first end face a to form a groove 105, and the through hole 101 penetrates through the first end face a to the bottom of the groove 105. It should be noted that the shape and size of the groove 105 can be set according to the position of the air outlet on the electronic cigarette stem B. In the embodiment, the groove 105 facilitates the air flowing to the groove 105 to enter the atomizer A from the through hole 101 by forming a large space, and the groove 105 also provides space for the arrangement of each of the pins 301.
Further, the second end face b of the base 10 is recessed to form a wire groove 106 communicating the accommodating groove 102 and the groove 105. When each of the pins 301 is bent, the steering portion 3012 is located in the wire groove 106, and the wire groove 106 serves to guide and limit each of the pins 301.
Further, both ends of the wire groove 106 extend towards the first end face a to form a slope 107, and the angle of inclination of the slope 107 is set to be greater than 2 degrees or match a bending angle of the steering portion 3012. It is easy to understand that the bent region of each of the pins 301 extending from the main body portion 3011 to the steering portion 3012 and the bent region extending from the steering portion 3012 to the connecting portion 3013 are guided and supported by the structural setting of the slope 107.
FIG. 11 is a structural diagram of a holder 40 according to embodiments of the present disclosure; FIG. 12 is a structural diagram of the holder 40 from another angle of view according to embodiments of the present disclosure; as shown in FIGS. 11 to 12 , in an embodiment, the atomizer A further comprises the holder 40. Specifically, both ends of the holder 40 are opened to form a cavity, and a first end of the holder 40 is aligned with the through hole 101 and fixedly arranged on the base 10. Further, the atomizing core 30 is aligned with the cavity and arranged at a second end of the holder 40. Therefore, each of the pins 301 can pass the through hole 101 through the cavity. In addition, when the user uses the electronic cigarette, the air can continue to flow through the cavity of the holder 40 after passing through the through hole 101.
In an embodiment, the first end of the holder 40 is provided with an air hole 401 and a wire hole 402. The air passing through the through hole 101 can continue to flow through the air hole 401. The size of the wire hole 402 is matched with the main body portion 3011 of each of the pins 301. The pin 301 passes through the through hole 101 via the wire hole 402, and the wire hole 402 serves to fix the main body portion 3011 to a certain extent.
In an embodiment, the base 10 is recessed from the first end face a towards the second end face b to form a notch groove 103, and the through hole 101 penetrates the bottom of the notch groove 103. Further, the first end of the holder 40 is fixedly arranged in the notch groove 103. It is easy to understand that the opening size of the notch groove 103 is small, and the first end of the holder 40 protrudes outward. Therefore, the first end of the holder 40 cannot be moved longitudinally under the restriction of the notch groove 103, thereby achieving fixation. It should be noted that since the base 10 is made of silicone, the holder 40 can be mounted by jacking in from the opening of the notch groove 103.
FIG. 13 is a structural diagram of a guide pipe 50 according to embodiments of the present disclosure; as shown in FIG. 13 , in an embodiment, the atomizer A further comprises the guide pipe 50. Specifically, an orifice of the guide pipe 50 is aligned with an opening at the second end of the holder 40, so as to ensure air flow. It should be noted that the guide pipe 50 is made of fiber or other materials which can permeate and adsorb tar. When the electronic cigarette is used, the tar adsorbed by the guide pipe 50 is heated and atomized by the atomizing core 30, and finally sucked by the user along with the air.
Further, FIG. 14 is a structural diagram of a bracket 60 according to embodiments of the present disclosure; as shown in FIG. 14 , in an embodiment, the atomizer A further comprises the bracket 60. The bracket 60 fixedly is connected to the holder 40 and the guide pipe 50 to support and fix the guide pipe 50.

In an embodiment, a guide groove 601 is formed on the bracket 60. Correspondingly, a first bulging portion 302 is formed on the atomizing core 30, and a second bulging portion 403 is formed on the holder 40. By sliding the first bulging portion 302 and the second bulging portion 403 into the guide groove 601, the position between the atomizing core 30 and the holder 40 can be relatively fixed, so that the position between the atomizing core 30 and the base 10 can be relatively fixed. In this way, the condition that each of the pins 301 cannot pass through the wire hole 402 of the holder 40 and the through hole 101 of the base 10 due to dislocation can be avoided.
FIG. 15 is a structural diagram of a storage cotton 70 according to embodiments of the present disclosure; as shown in FIG. 15 , in an embodiment, the atomizer A further comprises the storage cotton 70. The storage cotton 70 is sleeved on the holder 40 and the guide pipe 50, and a first end of the storage cotton 70 is attached to the first end face a of the base 10.

The end cover 80 is provided with a guide hole 801, and the guide hole 801 is aligned with the orifice of the guide pipe 50. Therefore, the atomized tar and the air entering the atomizer A can continue to flow through the guide hole 801.
Further, FIG. 18 is a structural diagram of a tar-absorbing cotton 90 according to embodiments of the present disclosure; as shown in FIG. 18 , the atomizer A further comprises the tar-absorbing cotton 90. The tar-absorbing cotton 90 is made of felt embroidery or other fiber materials that can absorb tar. The tar-absorbing cotton 90 is provided on the end cover 80. It should be noted that a leak 901 is arranged on the tar-absorbing cotton 90, and the leak 901 is aligned with the guide hole 801. Therefore, the atomized tar and the air entering the atomizer A can continue to flow through the leak 901. In the embodiment, the tar-absorbing cotton 90 is used for absorbing residual tar by surface tension of internal voids to prevent tar leakage.
In an embodiment, the end cover 80 is provided with a limit slot 802, and the shape and size of the limit slot 802 match those of the tar-absorbing cotton 90 which is arranged in the limit slot 802.
