[0052] Embodiment 1:

[0053] like Figure 1 As shown, Embodiment 1 of the present invention discloses an electronic cigarette rod 200, which is used to connect with the atomizer bomb 100. The connection structure between the cigarette rod 200 and the atomizer bomb 100 is as shown in FIG. Figure 2 and Figure 3 As shown, the atomizer bomb 100 includes a connection seat 101 located at one end of the atomizer bomb 100, and the connection seat 101 is made of magnetic material (magnetic material refers to a material that can be adsorbed by a magnet, such as iron, nickel, and cobalt). A first electrode 102, a second electrode 103, and an air inlet 104 are also provided at the end of the atomizer bomb 100. Since the structures of the first electrode 102, the second electrode 103, and the air inlet 104 in the atomizer bomb 100 are already well known to those skilled in the art, they are not described in detail here. At the same time, a connection port 211 is provided at one end of the cigarette rod (specifically, a connection port 211 is provided at one end of the cigarette rod housing 210), and the connection seat 101 on the atomizer bomb 100 is connected to the connection port 211 on the cigarette rod to connect the atomizer bomb 100 to the cigarette rod.

[0054] like Figures 4 to 7As shown, the state in which the connecting port 211 of the cigarette rod is vertically facing upward is used for description. The cigarette rod includes a cigarette rod housing 210, a bracket 220 and a sealing cover 230. The bracket 220 and the sealing cover 230 are both arranged inside the cigarette rod housing 210. The cross section on the cigarette rod housing 210 that is perpendicular to the length direction of the cigarette rod housing 210 is set as the first cross section. The bracket 220 includes a bracket body and a bracket plate 222. The shape of the bracket plate 222 is similar to the shape of the first cross section, but the size of the bracket plate 222 is smaller than the size of the first cross section; the bracket plate 222 is located above the bracket body, and the bracket body and the bracket plate 222 are integrally formed. The above-mentioned sealing cover 230 is covered on the bracket plate 222, and the sealing cover 230 is located above the bracket plate 222. The shape of the sealing cover 230 is the same as the shape of the first cross section, and the sealing cover 230 is made of silicone material. A battery 250 , a mainboard 240 , and a charging PCB board 260 are installed on the bracket body, and a charging interface 261 is provided on the charging PCB board 260 .

[0055] A fixing seat 245, a first pin 243 and a second pin 244 are provided on the upper portion of the main board 240. In this embodiment, the first pin 243 and the second pin 244 are arranged parallel to each other. Figure 8 As shown, the fixing seat 245 is provided with a first mounting groove 2451 and a second mounting groove 2453. A first through hole 2452 is provided above the first mounting groove 2451 on the fixing seat 245, and a second through hole 2454 is provided above the second mounting groove 2453 on the fixing seat. The first through hole 2452 is communicated with the first mounting groove 2451, and the second through hole 2454 is communicated with the second mounting groove 2453. A first mounting block 2431 is provided at the lower part of the first pin 243, and the shape of the first mounting block 2431 is the same as that of the first mounting groove 2451; a second mounting block 2441 is provided at the lower part of the second pin 244, and the shape of the second mounting block 2441 is the same as that of the second mounting groove 2453. The first pin 243 is installed in the fixing seat 245 from the bottom of the fixing seat 245 through the first installation groove 2451 and the first through hole 2452, the first installation block 2431 is located in the first installation groove 2451, the second pin 244 is installed in the fixing seat 245 from the bottom of the fixing seat 245 through the second installation groove 2453 and the second through hole 2454, and the second installation block 2441 is located in the second installation groove 2453. The fixing seat 245 is provided with a first positioning column 2455 and a second positioning column 2456 on the side facing the main board 240, and the fixing seat 245 is connected to the main board 240 through the first positioning column 2455 and the second positioning column 2456 (holes connected to the first positioning column 2455 and the second positioning column 2456 are provided on the main board 240).

[0056] like Figures 9 to 14As shown, the first pin needle 243 sequentially passes through the bracket plate 222 and the sealing cover 230 to connect with the first electrode 102 of the atomizer bomb 100, and the second pin needle 244 sequentially passes through the bracket plate 222 and the sealing cover 230 to connect with the second electrode 103 of the atomizer bomb 100, and the direction from the first pin needle 243 to the second pin needle 244 is set as the first direction (as shown in FIG. Fig.10 As shown by the arrow D in the middle. A first magnet 231 and a second magnet 232 are provided on the bracket plate 222. The first magnet 231 and the second magnet 232 are both in the shape of strips. The first magnet 231 and the second magnet 232 are respectively located on opposite sides of the first direction (i.e., the first magnet 231 is located on one side of the line connecting the first pin 243 and the second pin 244, and the second magnet 232 is located on the other side of the line connecting the first pin 243 and the second pin 244). The length direction of the first magnet 231 is parallel to the first direction, the length direction of the second magnet 232 is parallel to the first direction, and the projection of the first magnet 231 in the first direction does not overlap with the projection of the second magnet 232 in the first direction. A third mounting groove and a fourth mounting groove are provided on the surface of the bracket plate 222 facing the sealing cover 230. The shape of the third mounting groove is the same as that of the first magnet 231, and the first magnet 231 is installed in the third mounting groove; the shape of the fourth mounting groove is the same as that of the second magnet 232, and the second magnet 232 is installed in the fourth mounting groove. The first magnet 231 passes through the sealing cover 230 upwards and is connected to the connecting seat 101 of the atomizer bomb 100 , and the second magnet 232 passes through the sealing cover 230 and is connected to the connecting seat 101 of the atomizer bomb 100 .

[0057] The working principle of the electronic cigarette rod in Example 1 is as follows: since the connection base 101 of the atomizer bomb 100 is made of magnetic material, the first magnet 231 and the second magnet 232 adsorb the connection base 101 of the atomizer bomb 100 through magnetic force; the first magnet 231 and the second magnet 232 are respectively located on opposite sides of the first direction, and the projection of the first magnet 231 in the first direction and the projection of the second magnet 232 in the first direction do not overlap, ensuring that a larger distance is separated between the first magnet 231 and the second magnet 232, so that the distance between the two magnetic connection points of the atomizer bomb 100 and the cigarette rod is longer, thereby This makes the connection between the atomizer bomb 100 and the cigarette rod more stable (during the normal connection between the atomizer bomb 100 and the cigarette rod, the atomizer bomb 100 is not easily affected by the force parallel to the length direction of the cigarette rod, that is, the force along the direction of pulling the atomizer bomb 100 out of the cigarette rod. The force applied to the atomizer bomb 100 is mostly perpendicular to the length direction of the cigarette rod. The force perpendicular to the length direction of the cigarette rod causes the atomizer bomb 100 to rotate easily, and the distance between the two magnetic connection points of the atomizer bomb 100 and the cigarette rod is longer, so that the torque of the atomizer bomb 100 to resist rotation is greater, thereby improving the connection stability between the atomizer bomb 100 and the cigarette rod).

[0058] Embodiment 2:

[0059] like Fig.15 As shown, the electronic cigarette rod in Example 2 of the present invention is improved on the basis of Example 1. Specifically, an air outlet 233, an air inlet channel 272 and a negative pressure channel 273 are provided in the cigarette rod. When the cigarette rod is connected to the atomizer bomb 100, the air outlet 233 is connected to the air inlet 104 of the atomizer bomb 100. The air inlet channel 272 is connected to the atmosphere outside the cigarette rod, and the air inlet channel 272 is connected to the air outlet 233; a microphone switch 271 is provided in the negative pressure channel 273, and the negative pressure channel 273 is connected to the air outlet 233. When the above-mentioned air outlet 233 is inhaled (that is, when the electronic cigarette is used), the air outside the cigarette rod passes through the air inlet pipe and the air outlet 233 to enter the air inlet 104 of the atomizer bomb 100, and the air in the negative pressure channel 273 passes through the negative pressure channel 273 and the air outlet 233 in turn to enter the air inlet 104 of the atomizer bomb 100, and a negative pressure is formed in the negative pressure channel 273. The microphone switch 271 is electrically connected to the control unit in the cigarette holder.

[0060] The working principle of the electronic cigarette rod in Example 2 is as follows: when the user inhales the electronic cigarette, the air outside the cigarette rod passes through the air inlet duct and the air outlet 233 into the air inlet 104 of the atomizer cartridge 100, and the air in the negative pressure channel 273 passes through the negative pressure channel 273 and the air outlet 233 in turn into the air inlet 104 of the atomizer cartridge 100, forming a negative pressure in the negative pressure channel 273. At this time, the microphone switch 271 works to generate a first signal. After receiving the first signal, the control unit controls the atomizer in the atomizer cartridge 100 to work and atomize the tobacco oil in the atomizer cartridge 100 (the structure and working principle of the atomizer are well known to those skilled in the art and will not be described in detail here).

[0061] The rest of the structure and working principle of Example 2 are the same as those of Example 1.

[0062] Embodiment 3:

[0063] like Fig.16 As shown, the electronic cigarette rod in embodiment 3 of the present invention is improved on the basis of embodiment 2. Specifically, a liquid storage chamber 274 is further provided in the cigarette rod, the air inlet channel 272 is connected with the air outlet 233 through the liquid storage chamber 274, and the negative pressure channel 273 is connected with the air outlet 233 through the liquid storage chamber 274.

[0064] The working principle of the electronic cigarette rod in Example 2 is as follows: when the electronic cigarette is in use, condensate will form in the air inlet 104 of the atomizer cartridge 100. When the condensate flows into the air outlet 233 through the air inlet 104, it will be stored in the liquid storage chamber 274 for storage, thereby preventing the condensate from flowing into the negative pressure channel 273 and affecting the operation of the microphone switch 271.

[0065] Embodiment 3:

[0066] like Figures 9 to 14 As shown, the electronic cigarette rod in Example 3 of the present invention is improved on the basis of Example 2. Specifically, an annular convex rib 275 is provided on the side of the bracket plate 222 facing the sealing cover 230, and a liquid storage tank 2741 and a first groove 2731 are formed inside the annular convex rib 275. The liquid storage tank 2741 is connected to the first groove 2731, and the groove depth of the liquid storage tank 2741 is greater than the groove depth of the first groove 2731. The liquid storage tank 2741 and the sealing cover 230 on the side facing the bracket plate 222 form a liquid storage chamber 274, and the first groove 2731 and the sealing cover 230 on the side facing the bracket plate 222 form the negative pressure channel 273. A second groove 2721 is also provided on the annular convex rib 275, one end of the second groove 2721 is connected to the outside of the annular convex rib 275, and the other end of the second groove 2721 is connected to the inside of the annular convex rib 275, and the second groove 2721 and the sealing cover 230 on the side facing the bracket plate 222 form an air intake section 2722. An air intake hole 212 is provided at a position of the cigarette rod housing 210 relative to the air intake section 2722, and the air intake hole 212 and the air intake section 2722 together form the air intake channel 272.

[0067] Meanwhile, in this embodiment, a first protrusion is provided between the liquid storage tank 2741 and the first groove 2731, and the two ends of the first protrusion are respectively connected to the inner wall of the annular convex rib 275, and the height of the first protrusion is lower than the height of the annular convex rib 275. A second protrusion is also provided in the first groove 2731, and the second protrusion is located between the first protrusion and the microphone switch 271, and the two ends of the second protrusion are respectively connected to the inner wall of the annular convex rib 275, and the height of the second protrusion is lower than the height of the annular convex rib 275, and the height of the second protrusion is higher than the height of the first protrusion.

[0068] In this embodiment, the microphone switch 271 includes a microphone 241 and a microphone cover 242. Fig.12 As shown, the microphone 241 is arranged in the negative pressure channel 273, the microphone cover 242 is annular, and the microphone cover 242 is made of silicone material. The inner wall of the negative pressure channel 273 is wrapped on the outer ring of the microphone cover 242, and the inner ring of the microphone cover 242 is wrapped on the outside of the microphone 241 (that is, the microphone cover 242 seals the inner wall of the negative pressure channel 273 and the microphone 241).

[0069] The working principle of the electronic cigarette rod in Example 3 is as follows: when the electronic cigarette is in use, condensate will form in the air inlet 104 of the atomizer cartridge 100. When the condensate flows into the air outlet 233 through the air inlet 104, it will be stored in the liquid storage chamber 274 for storage. At the same time, a first protrusion and a second protrusion are provided to further limit the condensate from flowing to the microphone switch 271.

[0070] Embodiment 4:

[0071] like Figure 2 As shown, the electronic cigarette rod in the fourth embodiment of the present invention is improved on the basis of the third embodiment. Specifically, a fingerprint recognition module 280 is further provided on the cigarette rod housing 210. Fig.17 As shown, the fingerprint recognition module 280 includes a light guide cover plate 281, a light emitting layer 282 and a fingerprint recognition unit 283. The light guide cover plate 281 is arranged on the cigarette rod housing 210. The cigarette rod housing 210 is provided with a third through hole 213 for installing the light guide cover plate. The light emitting layer 282 is attached to the inner surface of the light guide cover (the surface of the light guide cover plate 281 facing the inside of the cigarette rod housing 210 is the inner surface). The light emitting layer 282 is used to emit light, and the light emitted by the light emitting layer 282 passes through the light guide cover plate 281. The fingerprint recognition unit 283 is an ultrasonic under-screen fingerprint chip. The fingerprint recognition unit 283 is attached to the inner surface of the light emitting layer 282 (the surface of the light emitting layer 282 facing the inside of the cigarette rod housing 210 is the inner surface). The fingerprint recognition unit 283 and the light emitting layer 282 are electrically connected to the control unit respectively.

[0072] In this embodiment 4, a Bluetooth chip is also provided in the cigarette rod housing 210, and the Bluetooth antenna of the Bluetooth chip is arranged on the inner surface of the light guide cover 281. The light guide cover 281 is made of non-metallic material. In this embodiment, the light guide cover 281 is made of plastic material (it can also be made of glass material).

[0073] The working principle of the electronic cigarette rod in Example 4 is: the user places his finger on the light guide cover 281, and the fingerprint recognition unit 283 collects the user's fingerprint. When the similarity between the user's fingerprint image and the preset fingerprint image reaches a preset value, the light-emitting layer 282 is driven to emit light (the preset fingerprint image is the fingerprint image collected when the user uses the electronic cigarette for the first time), and the light passes through the light guide cover 281 and is received by the user, so that the verification success information is fed back to the user after the user's fingerprint verification is successful.

[0074] At the same time, the Bluetooth antenna of the Bluetooth chip is arranged on the inner surface of the light guide cover 281, and the light guide cover 281 is made of non-metallic material. The Bluetooth signal can easily pass through the non-metallic material, thereby ensuring that the Bluetooth signal transmission is not interfered with (the existing cigarette rod shell 210 is made of metal material, and the Bluetooth antenna is located inside the cigarette rod shell 210, and the wall surface of the cigarette rod shell will interfere with the output of the Bluetooth signal).

[0075] Embodiment 5:

[0076] The electronic cigarette rod in the fifth embodiment of the present invention is improved on the basis of the fourth embodiment. Specifically, the structure of the fingerprint recognition module 280 on the cigarette rod housing 210 is different, such as Figures 18 to 20As shown, the fingerprint recognition module 280 also includes a light guide cover plate 281, a light emitting layer 282 and a fingerprint recognition chip 283. The light guide cover plate is annular, the light emitting layer is also annular, and the fingerprint recognition chip is cylindrical. The light guide cover plate 281 is arranged on the cigarette rod housing 210, and the cigarette rod housing 210 is provided with a third through hole 213 for installing the light guide cover plate. The light emitting layer 282 is attached to the inner surface of the light guide cover plate (the inner diameter and outer diameter of the annular light emitting layer are the same as those of the annular cover plate, and the surface of the light guide cover plate 281 facing the inside of the cigarette rod housing 210 is the inner surface), and the light emitting layer 282 is used to emit light, and the light emitted by the light emitting layer 282 passes through the light guide cover plate 281. The fingerprint recognition chip 283 is a capacitive fingerprint recognition chip, and the fingerprint recognition chip 283 is arranged in the inner hole of the light guide cover plate. After such setting, the user places his finger on the fingerprint recognition chip 283, and the fingerprint recognition chip 283 collects the user's fingerprint. When the similarity between the user's fingerprint image and the preset fingerprint image reaches a preset value, the light-emitting layer 282 is driven to emit light (the preset fingerprint image is the fingerprint image collected when the user uses the electronic cigarette for the first time). Since the light-emitting layer is annular, the user's finger can only block a part of the light emitted by the light-emitting layer, and the light emitted by the light-emitting layer 282 passes through the light-guiding cover plate 281 and is received by the user, so that after the user's fingerprint verification is successful, the verification success information is fed back to the user.

[0077] The remaining structure and working principle of Example 5 are the same as those of Example 4.

[0078] Embodiment 6:

[0079] Embodiment 6 of the present invention discloses an electronic cigarette, which includes an atomizer cartridge and any one of the electronic cigarette rods in Embodiments 1 to 5.

[0080] After the electronic cigarette in the sixth embodiment of the invention adopts the above structure, the electronic cigarette can identify the fingerprint of the user. When the similarity between the user's fingerprint image and the preset fingerprint image reaches a preset value, the light-emitting layer is driven to emit light, and the light passes through the light-guiding cover plate and is received by the user, so that after the user's fingerprint is successfully verified, the verification success information is fed back to the user.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
