Example 1:

as shown in fig. 1 and 2, the present embodiment provides an e-cigarette rod using magnetic coupling. Wherein the tobacco rod 2000 is used in conjunction with a cartridge 1000 capable of atomizing tobacco tar. A power supply 240 in the tobacco rod 2000 provides electrical power to the atomizing means of the cartridge 1000. The tobacco rod 2000 includes a power source 240 and control circuitry. The control circuitry therein is typically integrated on the PCB board 250. And the atomization device in the cartridge 1000 converts electrical energy into heat to atomize the tobacco tar stored in the sump of the cartridge 1000. When the user inhales at the mouthpiece, a negative pressure is created at the tobacco tar outlet of the cartridge 1000 already atomized by the device. Under the action of negative pressure, air enters the cartridge 1000 from the air inlet of the cartridge 1000 and brings atomized tobacco tar to the smoking port of the mouthpiece along the internal airflow channel of the cartridge 1000 for the user to smoke. The control circuit in the electronic cigarette rod adopting magnetic connection in the embodiment can utilize the bluetooth module 220 in the cigarette rod 2000 to communicate with other devices with the bluetooth module 220, such as mobile terminals like mobile phones, intelligent electric appliances like air conditioners, air purifiers, etc., and can receive information sent by these devices or send information to these devices.

In the electronic cigarette rod adopting magnetic connection of the embodiment, the magnetic element 300 and the mounting base 214 are formed into an integrated in-mold injection structure through in-mold injection. By adopting the mode of in-mold injection molding of the magnetic element 300 and the mounting seat 214, the structure of integrating the magnetic element 300 and the mounting seat 214 can be directly obtained, so that the magnetic element 300 can be accurately and reliably fixed on the support 210 without additionally assembling the magnetic element 300 and the support 210, and the connection between the cartridge 1000 and the cigarette rod 2000 can be conveniently and reliably ensured. Meanwhile, a complex assembly process is omitted, and a related professional is not required to specially manufacture and use a clamp to assist assembly, so that the production cost and the labor cost are reduced.

wherein the control circuitry may be integrated on the PCB board 250.

The bracket 210 is used for mounting the PCB 250 and the power supply 240, the bracket 210 is formed with a mounting seat 214, and the mounting seat 214 is positioned at one end of the bracket 210 opposite to the PCB 250 along the length direction of the cigarette rod 2000;

as shown in fig. 4, in which the bracket 210 serves as a base for mounting the main components of the cigarette rod 2000, components including the bluetooth module 220 and the microphone may also be mounted on the bracket 210.

The housing 230 is provided with an accommodating chamber, and is sleeved with the bracket 210, and the PCB board 250 and the power supply 240 are located in the accommodating chamber;

the outer casing 230 is a hollow structure, and the rest of the components of the cigarette rod 2000 are all wrapped in the outer casing 230. In order to ensure a certain structural strength and prevent important parts in the housing 230 from being damaged by external force, the housing 230 may be made of a metal material.

The magnetic element 300 is used for enabling the cigarette rod 2000 and the cigarette cartridge 1000 to be connected through magnetic attraction force generated by the magnetic element 300 on the cigarette cartridge 1000, the magnetic element 300 and the mounting seat 214 are integrally formed through in-mold injection molding, and the magnetic element 300 is located on one side, facing the cigarette cartridge 1000, of the mounting seat 214.

The magnetic element 300 is an element that can generate a magnetic field with a certain intensity in a certain range, such as a magnet. Accordingly, a component made of ferromagnetic material is provided on the cartridge 1000. Wherein the in-mold injection molding is an existing integrated forming process. The magnetic element 300 and the mounting base 214 are molded in a mold to form an integrated in-mold structure. The in-mold injection molding process of the magnetic element 300 is to place the needle of the magnetic element 300 in a mold, and then inject the injection molding material into the mold, so as to finally form the integrated product of the magnetic element 300 and the mounting seat 214. By adopting the mode of in-mold injection molding of the magnetic element 300 and the mounting seat 214, the structure of integrating the magnetic element 300 and the mounting seat 214 can be directly obtained, so that the magnetic element 300 can be accurately and reliably fixed on the support 210 without additionally assembling the magnetic element 300 and the support 210, and the connection between the cartridge 1000 and the cigarette rod 2000 can be conveniently and reliably ensured. Meanwhile, a complex assembly process is omitted, and a related professional is not required to specially manufacture and use a clamp to assist assembly, so that the production cost and the labor cost are reduced.

The mounting seat 214 is further provided with a positioning groove 215, the positioning groove 215 is formed by the end surface of the mounting seat 214 opposite to the PCB 250 sinking towards one side of the PCB 250, the positioning groove 215 is formed with a positioning hole 217 covering the outer surface of the magnetic element 300, the magnetic element 300 is formed by extending the bottom surface of the positioning hole 217 towards the smoke cartridge 1000, and the end surface of the magnetic element 300 facing the smoke cartridge 1000 is away from the mounting groove 213 by a preset distance. In order to ensure the reliability of the assembly of the cartridge 1000 and the rod 2000, it is necessary to have the magnetic element 300 in good contact with the ferromagnetic parts of the cartridge 1000 during assembly. For this purpose, the positioning slot 215 is provided on the mounting 214, and the positioning slot 215 can accurately define the position of the magnetic element 300 in the length direction of the cigarette rod 2000. In addition, in order to make the integrated structure formed by the magnetic element 300 and the bracket 210 after the in-film injection molding have better structural strength, in the embodiment, the positioning hole 217 is arranged on the positioning groove 215, and the positioning hole 217 is coated on the outer surface of the magnetic element 300, so that the magnetic element 300 can be better integrated with the mounting seat 214. The magnetic element 300 can be a cylindrical structure, correspondingly, the positioning hole 217 is a blind hole, and the bottom of the magnetic element 300 is attached to the bottom of the blind hole after the membrane is formed by injection molding, so that the magnetic element 300 and the bracket 210 can be stressed as a whole.

Example 2

As shown in fig. 2, 4 and 5, in the present embodiment, the electronic cigarette rod using magnetic connection further includes:

a sealing member 280, the sealing member 280 being used to form a seal between the inner wall of the housing 230 and the outer wall of the bracket 210 to prevent condensate from flowing to the PCB board 250 through a gap between the inner wall of the housing 230 and the outer wall of the bracket 210.

When assembled, the bracket 210, to which other parts are mounted, is inserted into the housing 230 with a certain gap between the outer wall of the bracket 210 and the inner wall of the housing 230. Condensate generated by the electronic cigarette can flow to the positions of the PCB board 250 and the battery through the gap between the outer wall of the bracket 210 and the inner wall of the housing 230, and a short circuit is easy to exist, so that the PCB board 250 is burnt. In this embodiment, the sealing member 280 is disposed between the bracket 210 and the housing 230, the sealing member 280 fills the gap between the outer wall of the bracket 210 and the inner wall of the housing 230, and a relatively independent space surrounding the PCB 250 and the battery is formed by the outer wall of the bracket 210, the inner wall of the housing 230 and the sealing member 280, so that external condensate is prevented from flowing to the PCB 250 and the battery.

In this embodiment, the sealing member 280 is an annular sealing member 280 surrounding the outer wall of the holder 210 by at least one circle, one side of the annular sealing member 280 facing the holder 210 abuts against the outer wall of the holder 210, and the other opposite side abuts against the inner wall of the housing 230 to form a seal between the inner wall of the housing 230 and the outer wall of the holder 210, and the sealing member 280 is located at one end of the holder 210 close to the cartridge 1000. The sealing member 280 may be made of a material with good elasticity, such as silica gel, and after the assembly, the sealing member 280 may be tightly abutted against the bracket 210 and the housing 230 by means of the property of recovering the elastic deformation, so as to avoid leaving a gap.

Since the holder 210 is intended to nest within the housing 230, the gap between the holder 210 and the housing 230 also surrounds the outer wall of the holder 210 at the end of the holder 210 adjacent the cartridge 1000. In this embodiment, the sealing member 280 is also configured to surround the bracket 210, and the sealing member 280 separates the portion of the bracket 210 where the battery and the PCB 250 are mounted from other portions where condensation is likely to occur by surrounding at least one circumference of the outer wall of the bracket 210 and forming a blocking surface on the cross section of the rod 2000 together with the bracket 210 and the housing 230. The sealing member 280 abuts on one side against the outer wall of the bracket 210 and on the opposite side against the inner wall of the housing 230, so that the sealing member 280 completely closes the gap between the bracket 210 and the housing 230, and thus the condensate is effectively prevented from flowing from the gap between the bracket 210 and the housing 230 to the PCB board 250 and the battery.

The bracket 210 is provided with an annular mounting groove 213, the mounting groove 213 is formed by recessing the outer wall of the bracket 210 to a predetermined depth in a direction opposite to the housing 230, one side of the annular sealing member 280 is embedded in the mounting groove 213, and the other opposite side is exposed out of the mounting groove 213 to abut against the inner wall of the housing 230.

In a specific application, the depth of the mounting groove 213 is adapted to the size of the cross section of the sealing member 280, such that after a portion of the sealing member 280 is inserted into the mounting groove 213, another portion of the sealing member 280 can be tightly pressed against the housing 230. The depth of the mounting groove 213 is set according to the size of the cross section of the sealing member 280 to control the abutting degree of the sealing member 280 with the housing 230, thereby adjusting the sealing effect and the assembling position of the bracket 210 and the housing 230.

In this embodiment, the sealing member 280 is formed around the bracket 210 along the circumferential direction of the outer wall of the bracket 210, one side of the sealing member 280 facing the bracket 210 abuts against the outer wall of the bracket 210, the opposite side abuts against the inner wall of the housing 230, and the sealing member 280 and the end surface of the bracket 210 facing the cartridge 1000 are spaced from each other by a predetermined distance along the length direction of the housing 230, so as to limit the relative positions of the housing 230 and the bracket 210 along the length direction of the housing 230 after the sealing member 280 abuts against the housing 230. The size of the cross-section of the housing 230 may gradually decrease along the length of the housing 230.

When the sealing member 280 is mounted on the mounting groove 213, the bracket 210 with the sealing member 280 mounted thereon is inserted into the housing 230, and the sealing member 280 is caught between the housing 230 and the bracket 210 after the bracket 210 has entered the housing 230 to a certain depth, the relative positions of the bracket 210 and the housing 230 are also locked, so that the relative positions between the bracket 210 and the housing 230 can be defined by setting the position of the sealing member 280 on the bracket 210 along the length direction of the housing 230 after assembly.

Example 3

As shown in fig. 2 and 5, in this embodiment, the cigarette rod 2000 further includes a ping needle 290, the ping needle 290 is integrally formed with the mounting seat 214 by injection molding, the ping needle 290 is used for forming an electrical connection between the PCB 250 located inside the cigarette rod 2000 and the atomization device located outside the cigarette rod 2000, and both ends of the ping needle 290 are respectively located at both sides of the mounting seat 214 along the length direction of the cigarette rod 2000.

The ping needle 290 and the mounting base 214 are molded to form an integrated in-mold structure. The in-mold injection molding process of the ping needle 290 includes placing the ping needle 290 at a specific position in a mold, and then injecting an injection molding material into the mold to finally form a product with the ping needle 290 and the mounting base 214 integrated.

In this embodiment, the ping pin 290 is used as a conductive element, one end of the ping pin 290 can be electrically connected to the PCB 250 by soldering, and the other end is in contact with the conductive element on the cartridge 1000. The power supply 240 thus increases the power conducted from the PCB 250 to the ping pin 290, through the ping pin 290 to the conductive element on the cartridge 1000, and from there to the heating element of the atomizer device to generate heat for atomizing the liquid smoke.

When the cartridge 1000 is assembled to the rod 2000, the cartridge 1000 and the PCB 250 are located on opposite sides of the mounting block 214, and when the holder 210 is inserted into the housing 230, the PCB 250 is separated from the atomizing device in the cartridge 1000 by the mounting block 214. Since the prior art is to form the mounting hole on the mounting seat 214 and then to fit the ping pin 290 into the mounting hole, a gap is easily formed between the ping pin 290 and the mounting hole, and condensate generated in the cartridge 1000 flows from the side of the mounting seat 214 close to the cartridge 1000 to the side of the mounting seat 214 close to the PCB 250 through the gap between the ping pin 290 and the mounting hole, so that the isolation effect of the mounting seat 214 is lost. Condensate in the cartridge 1000 may continuously flow to the PCB board 250 through the gap between the ping pin 290 and the mounting hole, causing damage to the PCB board 250.

In this embodiment, the prior art method of assembling the holder 210 and the ping needle 290 after they are separately manufactured is eliminated. Instead, the ping needle 290 as the conductive member is integrally formed with the mounting base 214 of the holder 210 by means of in-mold molding, using a structure in which the ping needle 290 is integrally formed with the holder 210. Thus, during the manufacturing process, the ping needle 290 and the bracket 210 do not need to be assembled, and the assembly gap between the ping needle 290 and the mounting seat 214 is not generated while the two ends of the ping needle 290 are respectively positioned at the two sides of the mounting seat 214. The condensate generated by the cartridge 1000 can not flow into the PCB 250 through the assembly gap between the ping pin 290 and the mounting seat 214, and the PCB 250 is effectively prevented from being damaged by the condensate.

As shown in fig. 7, in this embodiment, a positioning groove 215 is further disposed on the mounting base 214, the positioning groove 215 is formed by a depression toward one side of the PCB 250 from an end surface of the mounting base 214 opposite to the PCB 250, a through hole 216 covering an outer surface of the ping needle 290 is formed on the positioning groove 215, one end of the ping needle 290 and the end surface of the mounting base 214 facing the PCB 250 extend to a position electrically connected to the PCB 250, and the other end of the ping needle is exposed out of the positioning groove 215.

In order to accurately position the cartridge 1000 during assembly of the cartridge 1000, the positioning slot 215 is provided in the present embodiment. Wherein the positioning groove 215 is a groove depressed toward the slit direction of the PCB board 250. In order to enable the mounting seat 214 to form an integrated structure with the ping needle 290, in the present embodiment, a through hole 216 is provided on the positioning groove 215, and the through hole 216 is wrapped on the outer surface of the ping needle 290 by an injection molding method to form an integrated structure with the ping needle 290. The through holes 216 are formed along the grooves to extend a certain length toward both sides of the mounting seat 214 in the length direction of the cigarette rod 2000. Wherein the ping needle 290 comprises a head portion contacting with the cartridge 1000 and a tail portion connecting with the PCB board 250, and a step for positioning the relative position of the ping needle 290 and the mold during the in-mold injection is formed at the middle portion of the ping needle 290.

As shown in fig. 3, in this embodiment, the cigarette holder further includes a charging interface 260 and a bluetooth module 220, the charging interface 260 is electrically connected to the control board, the bluetooth module 220 and the charging interface 260 are located at two opposite ends of the PCB 250 along the length direction of the cigarette rod 2000, a receiving groove 251 is formed on the PCB 250, the power supply 240 is a battery, and the battery is placed in the receiving groove 251.

The PCB 250 is provided with a receiving groove 251 for receiving the battery, so that the PCB 250 is disposed at two ends of the battery in a straddling manner, and the battery can be embedded into the receiving groove of the PCB 250, thereby not increasing the width of the cigarette rod 2000 when the battery is mounted, and significantly reducing the overall size of the cigarette rod 2000. And both ends of the PCB board 250 in the length direction of the receiving groove 251 are connected to the positive and negative electrodes of the battery, respectively.
