Example 1:

as shown in fig. 1 and 2, the present embodiment provides an e-cigarette rod 2000 preventing backflow of condensate. 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 2000 for preventing the backflow of the condensed liquid 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.

As shown in fig. 2, the cigarette rod 2000 for preventing backflow of condensed liquid of the present embodiment is provided with a sealing member 280 between the holder 210 and the housing 230, and the sealing member 280 is used to fill a gap between the outer wall of the holder 210 and the inner wall of the housing 230, so that a relatively independent space surrounding the PCB 250 and the battery is formed by the outer wall of the holder 210, the inner wall of the housing 230 and the sealing member 280, and the external condensed liquid is prevented from flowing to the positions of the PCB 250 and the battery, thereby preventing the control circuit and the power supply 240 from being damaged.

As shown in fig. 2 and 3, the electronic cigarette rod 2000 for preventing backflow of condensed liquid of the present embodiment includes:

a power supply 240 for supplying electrical power to the electronic cigarette;

wherein, the power supply 240 can supply power for the circuit board of the electronic cigarette, the bluetooth module 220, the atomization device and other devices.

A PCB board 250 formed with a control circuit electrically connected to the power supply 240;

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

A conductive element 290 for forming an electrical connection between the PCB board 250 and the atomization device;

the power supply 240 delivers electrical power to the conductive element 290 through the PCB 250, and the conductive element 290 delivers electrical current to the aerosolization device by contacting the conductive member of the cartridge 1000.

A bracket 210 for mounting the PCB 250, the power supply 240 and the conductive member 290, the conductive member 290 being mounted at an end of the bracket 210 opposite to the PCB 250;

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;

as shown in fig. 5, the housing 230 is a hollow structure, and the rest of the components of the tobacco rod 2000 are all wrapped in the housing 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.

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.

As shown in fig. 4, in the present embodiment, an annular mounting groove 213 is formed on the holder 210, the mounting groove 213 is formed by recessing the outer wall of the holder 210 by a predetermined depth in a direction opposite to the housing 230, one side of the annular sealing member 280 is inserted into the mounting groove 213, and the 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.

The bracket 210 is formed with a mounting hole for mounting a conductive member 290, which is located at a side of the sealing member 280 opposite to the PCB board 250.

Since the conductive member 290 needs to be in contact with the cartridge 1000, the condensate generated from the part of the cartridge 1000 is easy to flow from one side of the conductive member 290 to the PCB 250, and in this embodiment, the PCB 250 and the conductive member 290 are respectively located at two ends of the sealing member 280, so that the condensate generated from the cartridge 1000 cannot flow from the position of the conductive member 290 to the position of the PCB 250 due to the blocking effect of the sealing member 280.

Example 2

As shown in fig. 4, in this embodiment, the control circuit is electrically connected to the power supply 240, a second height limiting structure 212 for limiting a height position of an upper surface of the PCB 250 and a second height limiting structure for limiting a height position of a lower surface of the PCB 250 are formed on the bracket 210, and the PCB 250 is clamped between the second height limiting structure 212 and the second height limiting structure.

The tobacco rod 2000 is mainly used for providing electric energy for the atomization device in the cartridge 1000. The tobacco rod 2000 thus includes a power supply 240 and control circuitry. The control circuitry therein is typically integrated on the PCB board 250. In order to reliably connect the PCB 250 to other electrical components, the exact position of the PCB 250 in the tobacco rod 2000, especially in the height direction, must be ensured when assembling the tobacco rod 2000.

In order to accurately position and reliably mount the PCB 250, in this embodiment, a second height limiting structure 212 for limiting the height position of the upper surface of the PCB 250 and a second height limiting structure for limiting the height position of the lower surface of the PCB 250 are formed on the bracket 210, and the PCB 250 is clamped between the second height limiting structure 212 and the second height limiting structure.

Wherein the first height position defined by the second height limiting structure 212 is an ideal position at which the lower surface of the PCB 250 is mounted, and the second height position defined by the second height limiting structure is an ideal position at which the upper surface of the PCB 250 is mounted. Since the PCB board 250 has a certain thickness and an appropriate installation gap may be left for the convenience of installation operation, the first preset distance of the second height position from the first height position may be determined according to the thickness of the PCB board 250 and the installation gap. In this embodiment, the positions at the two ends of the PCB 250 are accurately limited by the second height limiting structures 212 and the second height limiting structures, respectively, and the first height limiting structures can be arranged in pairs, so that at least 3 limiting points can be formed on the upper and lower surfaces of the PCB 250, the height of the PCB 250 can be accurately limited by the limiting points at the positions, and the stability of the PCB 250 in the height direction when the PCB 250 is installed in the cigarette rod 2000 is ensured under the constraint of the at least three limiting points. During specific installation, the PCB 250 is inserted between the second limiting structure and the first limiting structure along the direction parallel to the PCB 250.

As shown in fig. 3, in order to charge the power source 240 of the cigarette rod 2000 in time and enable the cigarette rod 2000 to be continuously used for a long time, in this embodiment, the cigarette rod further includes a charging interface 260, 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 source 240 is a battery, and the battery is placed in the receiving groove 251.

In this embodiment, the accommodating groove 251 for accommodating the battery is disposed on the PCB 250, so that the PCB 250 spans over two ends of the battery, and the battery can be embedded into the accommodating groove of the PCB 250, thereby not increasing the width of the tobacco rod 2000 when the battery is installed, and significantly reducing the overall size of the tobacco 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. Because the PCB board 250 has better structural strength, the adoption of the arrangement mode can reduce the width size of the tobacco rod 2000 and improve the reliability of the connection of the positive electrode and the negative electrode of the battery by utilizing the structural strength of the PCB board 250. In addition, in this embodiment, 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, so that the cigarette rod 2000 can be conveniently connected to a charging device at the end for charging, and the charging process is controlled by the control circuit on the PCB 250.

Control circuitry on PCB board 250 controls bluetooth module 220 to receive or transmit information through bluetooth module 220 as required by the application.

As shown in fig. 5, the housing 230 is often made of a metal material. However, the metal shields the bluetooth signal, so the embodiment may provide an opening 232 on the metal housing 230, and the size of the opening 232 may be determined according to the requirement of the bluetooth signal propagation strength. The bluetooth signal emitted from the bluetooth module 220 in the housing 230 may be propagated from the set opening 232 of the metal housing 230 to the outside of the metal housing 230. External bluetooth signals may also enter the metal housing 230 from an opening 232 provided in the metal housing 230. The bluetooth module 220 in the cigarette rod 2000 thus enables bluetooth communication with other devices through the opening 232 provided in the housing 230.

In order to prevent the substances such as dust and liquid which are easy to damage the important components in the tobacco rod 2000 from entering the tobacco rod 2000, the shielding member 270 is added in the embodiment, the shielding member 270 is used to seal the opening 232 on the metal shell 230, wherein the shielding member 270 can be made of plastic material, so that the important components of the tobacco rod 2000 are protected, and the bluetooth signal can smoothly pass through the opening 232 on the metal shell 230.

In this embodiment, the cigarette rod 2000 further includes a connecting member for forming a rigid connection between the bracket 210 and the outer casing 230 along the length direction of the outer casing 230 to define a relative position of the bracket 210 with respect to the outer casing 230 along the length direction of the outer casing 230, one end of the connecting member is connected to the bracket 210, the other opposite end is connected to the outer casing 230, a first connecting structure is formed on a side surface of the bracket 210 along the width direction of the outer casing 230, the first connecting structure is used for being connected to one end of the connecting member, and the end of the connecting member connected to the outer casing 230 is protruded to a first predetermined distance along the direction of the outer casing 230, the end of the connecting member opposite to the first connecting structure is connected to the outer casing 230, an escape space communicated with the first connecting structure is further formed on the bracket 210, and the escape space is located on one side or both sides of the first connecting structure along the length direction of the outer, the avoiding space is used for forming an operation space capable of applying radial force to the outer surface of the connecting piece near the outer surface of the connecting piece after the connecting piece is connected with the first connecting structure.

In this embodiment, the connector forms a rigid connection between the bracket 210 and the housing 230 along the length of the housing 230, so that the relative position of the bracket 210 with respect to the housing 230 along the length of the housing 230 is kept fixed, and the bracket 210 is prevented from sliding with respect to the housing 230. In particular, the two ends of the connector are connected to the housing 230 and the bracket 210, respectively. The position of antenna and the opening 232 of shell 230 in the shell 230 is also injectd by the accuracy like this, makes bluetooth signal can propagate through the opening 232 of shell 230 by furthest, makes the bluetooth signal that the electron cigarette is used for communicating can keep better intensity to let bluetooth communication's effect obtain showing promotion. In addition, since the connecting member fixes the housing 230 and the bracket 210, the bracket 210 does not slip out of the housing 230. In order to improve the effect of bluetooth communication, the bluetooth communication of the bluetooth module 220 mounted on the cradle 210 may be located at the middle position of the opening 232 by a connector.

In this embodiment, the first connecting structure may be a blind hole, and the connecting member may be a pin, one end of the pin is inserted into the blind hole and abuts against the bottom surface of the blind hole, and the other end of the pin is connected to the housing 230.
