The pair of pin electrodes 24 pass through the second fixing member 23 and are inserted into the fixing through-holes 251 in a one-to-one correspondence. The plug electrode 24 is in interference connection with the inner wall of the fixing through hole 251, and is electrically connected to the electrical lead.

Due to the flexible property of the fixing sleeve 25, the tightness of the electrical wire connection between the pin electrode 24 and the heating pin 22 and the connection stability between the pin electrode 24 and the fixing sleeve 25 are improved. In addition, the fixing sleeve 25 is made of a high-temperature resistant material so as to adapt to the high temperature generated by the pin electrode 24 in operation. Optionally, the fixing sleeve 25 is a silicone sleeve, but is not limited thereto, as long as the fixing sleeve 25 is made of a high-temperature-resistant flexible material.

Further, the second body 231 is provided with a pair of through holes 234. The pair of through holes 234 communicate with the second receiving grooves 233. Each through hole 234 includes a first hole portion 23a and a second hole portion 23 b. One end of the first hole 23a communicates with the second receiving groove 234, and the other end of the first hole 23a communicates with the second hole 23 b. The second hole portion 23b has a larger diameter than the first hole portion 23 a.

Each of the pin electrodes 24 includes a pin body 241 and a bottom 242. The bottom 242 is connected to one end of the latch body 241. The plug main body 241 penetrates the first hole 23a, and the bottom 242 is disposed in the second hole 23b with interference. The bottom 242 and the second hole portion 23b are fixedly connected by interference fit, and the plug main body 241 and the silicone sleeve 25 are fixedly connected by interference fit and are in interference contact with the lead of the heating pin 22 in the hole to realize electrical connection. In addition, the bottom area of the bottom portion 23b is larger than the bottom area of the plug main body 241, so that the bottom portion 23b of the plug electrode 24 is electrically connected with the contact terminal of the control circuit board.

According to the electronic smoking set provided by the embodiment of the application, the connection port is arranged at the first end of the smoking cup, the connection block is arranged on the peripheral side of the first fixing piece of the heating module, and the connection block and the connection port are connected in a rotating and buckling manner, so that the heating module is detachably connected with the smoking cup, and later maintenance is facilitated; in addition, the connector includes the fretwork portion of inserting that is used for inserting the connecting block and is used for with connecting block joint complex joint fretwork portion, and the connecting block joint is in joint fretwork portion, inserts the inner space and the outside air of fretwork portion intercommunication cavity. Because the connecting block joint is in joint fretwork portion to the vacant has left and has inserted fretwork portion, and inserts the intercommunication passageway that fretwork portion just in time regarded as the inner space of intercommunication cigarette cup cavity and outside air, thereby avoids additionally setting up this intercommunication passageway, has simplified the structure of this embodiment.

The electronic smoking set provided by the embodiment of the present application is described in detail above, and the principle and the implementation of the present application are explained in the present application by applying specific examples, and the description of the above embodiment is only used to help understanding the technical scheme and the core idea of the present application; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
