[0049] Please refer to Figures 1 to 3 , Figure 1 A schematic cross-sectional view of the electronic smoking device according to an embodiment of the present application; Figure 2 for Figure 1 Enlarged view of part A in the middle; Figure 3 This is a schematic diagram of the structure of the combination of the cigarette cup and the heating module of the electronic cigarette device according to the embodiment of the present application.

[0050] The embodiment of the present application provides an electronic smoking device 100 , which includes a cigarette cup 10 , a heating module 20 , a cigarette cup support 30 , a sealing cover 40 , an excitation coil 50 and a housing 60 .

[0051] The heating module 20 is detachably connected to the cigarette cup 10. The first end 10B of the cigarette cup 10 and the heating module 20 are fixedly arranged in the placement cavity 32a of the cigarette cup holder 30. The cigarette cup holder 30 and the sealing cover 40 are sealed and connected to form a sealed space 40a. The excitation coil 50 is arranged in the sealed space 40a and surrounds the outer circumference of the heating module 20. The excitation coil 50 is used to heat the heating module 20. The heating module 20 is used to heat tobacco products inserted into the placement cavity 32a, such as cigarette sticks, cigarette cartridges or bulk tobacco. The cigarette cup 10, the heating module 20, the cigarette cup holder 30, the sealing cover 40 and the excitation coil 50 are all arranged in the outer shell 60.

[0052] For details, please refer to Figure 3-Figure 5The cigarette cup 10 includes a cavity 11 with openings at opposite ends. The inner space 10a of the cavity 11 is used to place external tobacco products. The cavity 11 includes a first end 10B and a second end 10C that are arranged opposite to each other. The first end 10B and the second end 10C are both provided with openings. The side wall of the first end 10B is provided with at least two connection ports 12. Optionally, the number of the connection ports 12 is two, but is not limited thereto.

[0053] Each connection port 12 includes an insertion hollow portion 121 and a clamping hollow portion 122. The insertion hollow portion 121 is communicated with the clamping hollow portion 122. The insertion hollow portion 121 is used to insert the connection block 212.

[0054] The heating module 20 is connected to the first end 10B. Figure 6 and Figure 7 The heating module 20 includes a first fixing member 21 and a heating pin 22 , a second fixing member 23 , a plug electrode 24 and a fixing sleeve 25 .

[0055] The heating pin 22 is fixedly connected to one end of the first fixing member 21. The second fixing member 23 is fixedly connected to the other end of the first fixing member 21. The plug electrode 24 is disposed in the second fixing member 23 and electrically connected to the heating pin 22. The fixing sleeve 25 is disposed in the second fixing member 23.

[0056] The heating needle 22 includes a heating element 221, an outer cover 222 and a temperature sensing element 223. The temperature sensing element 223 is arranged on the heating element 221. The outer cover 222 is arranged on the peripheral side of the heating element 221. The outer cover 222 is fixedly connected to the first fixing member 21. A pair of electrical wires of the temperature sensing element 223 are connected to a pair of pin electrodes 24 in a one-to-one correspondence. Optionally, the temperature sensing element 223 is a thermocouple, but is not limited thereto.

[0057] Specifically, a recessed portion 224 is provided in the middle of the heating element 221. The temperature sensing element 223 is provided in the recessed portion 224 and is close to the heating element 221. Due to the skin effect, most of the induced current is on the surface of the heating element 221, and the surface temperature rises faster than the center temperature. Therefore, the temperature sensing element 223 is provided at the center position of the heating element 221 in the vertical direction, which improves the accuracy of the temperature sensing element 223 in collecting the actual temperature of the heating element 221.

[0058] Optionally, the outer cover 222 is a ceramic cover, but is not limited thereto.

[0059] Please refer to Figure 8-9 , and combined with Figure 2 and Figure 3The heating needle 22 is arranged in the cavity 11. The first fixing member 21 includes a first main body 211 and at least two connecting blocks 212. At least two connecting blocks 212 are arranged on the outer peripheral side of the first main body 211. The connecting blocks 212 and the connecting port 12 are snap-fitted in a one-to-one correspondence. Optionally, the number of the connecting blocks 212 is two.

[0060] The connecting block 212 is clamped in the clamping hollow portion 122. The insertion hollow portion 121 connects the inner space 10a of the cavity 11 with the outside air.

[0061] The electronic cigarette device 100 of this embodiment is provided with a connection port 12 at the first end 10B of the cigarette cup 10 and a connection block 212 on the peripheral side of the first fixing member 21 of the heating module 20. The connection block 212 and the connection port 12 are connected by a rotation snap, so that the heating module 20 and the cigarette cup 10 can be detachably connected, which is convenient for later maintenance. In addition, the connection port 12 includes an insertion hollow portion 121 and a clamping hollow portion 122. The connection block 212 is clamped in the clamping hollow portion 122, and the insertion hollow portion 121 connects the inner space 10a of the cavity 11 with the outside air. Since the connection block 212 is clamped in the clamping hollow portion 122, the insertion hollow portion 121 is left free, and the insertion hollow portion 121 just serves as a connecting channel connecting the inner space 10a of the cavity 11 of the cigarette cup 10 and the outside air, thereby avoiding the additional setting of the connecting channel and simplifying the structure.

[0062] Furthermore, in the electronic cigarette device 100 of this embodiment, taking the end surface of the first end 10B as the reference surface, the depth of the inserted hollow portion 121 is greater than the depth of the clamped hollow portion 122. This arrangement increases the area of ​​the space 10a in the communicating cavity 11, thereby increasing the flow rate of the outside air entering the inner space 10a per unit time.

[0063] Each connection port 12 further includes a connection hollow portion 113. The connection hollow portion 113 is connected between the insertion hollow portion 121 and the clamping hollow portion 122. The connection hollow portion 113 is extended along the circumferential direction of the cavity 11.

[0064] The width of the connecting hollow portion 113 is smaller than the width of the clamping hollow portion 122. This arrangement makes it difficult for the clamping portion 21b to be separated from the clamping hollow portion 122, further improving the connection stability between the first fixing member 21 and the cigarette cup 10.

[0065] Specifically, the extension direction of the insertion hollow portion 121 is perpendicular to the circumferential direction of the cavity 11 of the cigarette cup 10. The clamping hollow portion 122 and the connecting hollow portion 113 are arranged along the circumferential direction of the cavity 11. Such an arrangement facilitates the rotational clamping of the heating module 20 and the cigarette cup 10.

[0066] In addition, the connecting block 212 includes an abutting portion 21a and a clamping portion 21b. The abutting portion 21a is connected to the outer peripheral side of the first main body 211. The clamping portion 21b is convexly arranged at one end of the abutting portion 21a away from the first main body 211. The abutting portion 21a abuts against the inner wall of the cavity 11. The clamping portion 21b is clamped in the clamping hollow portion 122. The abutting portion 21a abuts against the inner wall of the cavity 11, that is, the abutting portion 21a and the inner wall of the cavity 11 are interference fit, which improves the connection stability between the first fixing member 21 and the cavity 11 of the cigarette cup 10.

[0067] Please refer to Figure 2 The cigarette cup support 30 includes a support body 31 and a cylindrical wall 32. The wall 32 is disposed at one end of the support body 31. The wall 32 surrounds and forms a placement cavity 32a.

[0068] The sealing cover 40 is disposed around the outer peripheral side of the wall 32. The sealing cover 40 is sealedly connected to the wall 32 and the bracket body 31 respectively to form a sealed space 40a.

[0069] The exciting coil 50 is disposed in the sealed space 40 a and is wound around the circumference of the wall 32 .

[0070] The first end 10B of the cigarette cup 10 and the heating module 20 are both disposed in the placement cavity 32a. The cigarette cup 10 further includes at least one ventilation hole 13. The second end 10C of the cigarette cup 10 is used to insert tobacco products. At least one ventilation hole 13 is disposed at the second end 10C and surrounds the outer peripheral side of the cavity 11. Optionally, the number of ventilation holes 13 is three, but is not limited thereto.

[0071] The outer wall of the cavity 11 and the inner wall of the wall 32 define an air passage D. One end of the air passage D is connected to the vent hole 13. The other end of the air passage D is connected to the inner space 10a of the cavity 11 by inserting the hollow portion 121.

[0072] The vent 13, the airway D, the inserted hollow portion 121 and the inner space 10a of the cavity 11 form an airway structure. Since the airway D is between the cigarette cup 10 and the cigarette cup holder 30, and air is a poor conductor of heat, the user can avoid the high temperature of the cigarette cup 10 being directly transmitted to the excitation coil 50 when smoking. At the same time, after the external air enters the airway D, it will be heated by the outer wall of the cavity 11 of the cigarette cup 10, and a preheating effect is obtained. In addition, the airway structure and the excitation coil 50 are completely isolated to prevent the odor generated by the heating of the excitation coil 50 from entering the airway structure and affecting the taste.

[0073] Please refer to Figure 8 and Fig. 9The first fixing member 21 further includes a base 213 and at least two matching blocks 214. The base 213 is connected to the other end of the first body 211. The matching blocks 214 are protruded on the outer peripheral side of the base 213. The outer peripheral wall of the base 213 protrudes from the outer peripheral wall of the first body 211. The matching blocks 214 and the wall 32 are interference fit.

[0074] The matching block 214 and the inner wall of the wall 32 are interference fit, so that the heating module 20 is fixed in the placement cavity 32a. In addition, the outer peripheral wall of the base 213 protrudes from the outer peripheral wall of the first body 211, and the protruding part of the base 213 is used to limit the first end 10B of the cigarette cup 10.

[0075] Please refer to Figure 7-Figure 11 , combined with Figure 2 The heating module 20 includes a second fixing member 23 . The base 213 is provided with a first receiving groove 215 and a clamping groove 216 . The clamping groove 216 is connected to the opposite side of the first receiving groove 215 .

[0076] The second fixing member 23 includes a second body 231 and a clamping protrusion 232. The clamping protrusion 232 is disposed on the opposite side of the second body 231. A portion of the second body 231 is inserted into the first receiving groove 215. The clamping protrusion 232 is clamped in the clamping groove 216.

[0077] The second fixing member 23 is used to fix the fixing sleeve 25. The first fixing member 21 and the second fixing member 23 are fixedly connected via the clamping groove 216 and the clamping protrusion 232.

[0078] The heating module 20 further includes a pair of plug electrodes 24 and a flexible fixing sleeve 25. A second receiving groove 233 is formed at one end of the second body 231 facing the first fixing member 21. The fixing sleeve 25 is disposed in the second receiving groove 233.

[0079] The fixing sleeve 25 defines two fixing through holes 251 . The electrical wires of the two heating pins 22 extend into the fixing through holes 251 in a one-to-one correspondence.

[0080] A 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 pin electrodes 24 are interference-connected with the inner wall of the fixing through holes 251 and are electrically connected to the electrical wire.

[0081] Due to the flexible nature of the fixing sleeve 25, the tightness of the electrical wire connection between the plug electrode 24 and the heating pin 22 and the connection stability between the plug electrode 24 and the fixing sleeve 25 are improved. In addition, the fixing sleeve 25 is also made of a high temperature resistant material to adapt to the high temperature generated by the plug electrode 24 during operation. Optionally, the fixing sleeve 25 is a silicone sleeve, but it is not limited thereto, as long as the fixing sleeve 25 is made of a high temperature resistant flexible material.

[0082] Further, the second body 231 is provided with a pair of through holes 234. The pair of through holes 234 are connected to the second receiving groove 233. Each through hole 234 includes a first hole portion 23a and a second hole portion 23b. One end of the first hole portion 23a is connected to the second receiving groove 233, and the other end of the first hole portion 23a is connected to the second hole portion 23b. The aperture of the second hole portion 23b is larger than the aperture of the first hole portion 23a.

[0083] Each plug electrode 24 includes a plug body 241 and a bottom 242. The bottom 242 is connected to one end of the plug body 241. The plug body 241 passes through the first hole portion 23a, and the bottom 242 is set in the second hole portion 23b with interference fit. The bottom 242 and the second hole portion 23b are fixedly connected by interference fit, and the plug body 241 and the fixing sleeve 25 are fixedly connected by interference fit, and are electrically connected to the lead wire of the heating pin 22 in the hole through interference contact. In addition, the bottom area of ​​the bottom 242 is larger than the bottom area of ​​the plug body 241, which facilitates the electrical connection between the bottom 242 of the plug electrode 24 and the contact terminal of the control circuit board.

[0084] The electronic cigarette device of the embodiment of the present application is provided with a connection port at the first end of the cigarette cup and a connection block on the peripheral side of the first fixing member of the heating module. The connection block and the connection port are connected by rotating snaps, so that the heating module and the cigarette cup can be detachably connected, which is convenient for later maintenance; in addition, the connection port includes an insertion hollow part for inserting the connection block and a clamping hollow part for clamping with the connection block. The connection block is clamped in the clamping hollow part, and the insertion hollow part connects the inner space of the cavity with the outside air. Since the connection block is clamped in the clamping hollow part, the insertion hollow part is left free, and the insertion hollow part just serves as a connecting channel connecting the inner space of the cigarette cup cavity with the outside air, thereby avoiding the additional setting of the connecting channel and simplifying the structure of the present embodiment.
