Fig. 1-5 are schematic diagrams of a power supply device of an aerosol generator according to a preferred embodiment of the present invention. The power supply device 100 includes a housing 1, a control board 4, a battery element 5, a USB interface 2, and a conductive member 3. The control board 4 and the battery element 5 are both installed in the housing 1, and the control board 4 is electrically connected with the battery element 5. The pin end 21 of the USB interface 2 is soldered to the control board 4, and the interface end 22 penetrates the housing 1 for power contact. The conductive member 3 is fitted to the interface end 22. When the conductive member 3 is inserted into the interface end 22, the control board 4 receives the first electrical signal short-circuited at the USB interface 2, and disconnects the output of the battery element 5, so that the battery element 5 is disconnected from an external load. When the conductive member 3 is taken out from the interface end 22, the control board 4 receives the second electrical signal that the USB interface 2 is not shorted, and turns on the output of the battery element 5, so that the battery element 5 is electrically connected to an external load. In the embodiment, the conductive piece 3 is configured to the USB interface 2 in a pluggable manner, so as to realize the connection and disconnection of the output circuit of the battery element 5, and effectively control the output of the battery element 5, thereby reducing the probability of the false output of the battery element 5 of the aerosol generator.

In the present embodiment, as shown in fig. 3 and 5, the housing 1 has a hollow structure, and a mounting bracket 11 is mounted on a first end of the housing, and the mounting bracket 11 is used for mounting electronic components such as the control board 4, the battery element 5, and the USB interface 2. The second end of the mounting bracket 11 opposite to the housing 1 encloses a mounting groove 12 for mounting an external load. The opening of the second end is the opening of the mounting groove 12. A first end of the housing 1 is provided with a clearance hole corresponding to the interface end 22, and the interface end 22 passes through the clearance hole and is exposed outside the housing 1 for plugging. The control panel can adopt a printed circuit board and is provided with various required components, such as an MCU, a switch, a charging protection circuit, an airflow sensor and the like. The USB interface 2 comprises a casing and a base, wherein a plug tongue 23 is convexly arranged on the base, and a plurality of pins 24 are arranged on the plug tongue 23 at intervals. The base is mounted to and closes the opening at one end of the housing to form a pin end 21. Correspondingly, the opening at the other end of the casing is not provided with the base, thus forming an interface end 22 for plugging. The base and/or the casing are provided with fixing pins, the USB interface 2 is fastened on the control panel 4 through the fixing pins, and meanwhile, the pins 24 are respectively electrically connected with pins corresponding to the MCU arranged on the control panel 4. The tongue 23 extends in the direction from the pin end 21 to the interface end 22. The casing inner wall is including being located respectively the upper wall and the lower wall of base upper and lower both sides, and be located respectively the both sides wall of base left and right sides. The insertion tongue 23 is arranged in parallel with the upper wall and the lower wall, and is arranged perpendicular to the two side walls. The tongue 23 may be attached to the upper wall or the lower wall, or may be located between the upper wall and the lower wall with a gap therebetween.

Further, the pins 24 may be disposed on one side of the tongue 23 facing the upper wall, may also be disposed on one side of the tongue 23 facing the lower wall, and of course, may also be respectively distributed on two sides of the tongue 23. The number of the plurality of pins 24 may be 2, 3, 4, 5 or more, and each pin 24 may define a function. In this embodiment, as shown in fig. 6 and 7, the IO pin in the MCU for detecting the USB interface 2 is configured in a pull-up mode, and the IO pin may be pulled up to a high level through a resistor inside the chip, or may be pulled up to a high level by adding a pull-up resistor in the circuit. The high level is the working voltage, and the IO pin data read from the program is 1. That is, when the interface terminal 22 of the USB interface 2 is normally plugged with an external power source or is not plugged, the IO pin senses a high level. When two adjacent pins in the USB interface 2 are turned on, the pull-up resistor in the circuit is short-circuited, so that the IO pin senses a low level, and the data of the pin read from the program is 0. At this time, the MCU transmits an electric signal to disconnect the output of the battery element 5. The conductive component 3 is configured to correspond to the position of the insertion tongue 23, and is detachably mounted on the interface end 22 and short-circuits the USB interface 2. The conductive member 3 is made of a conductive material. Preferably, the conductive silicone rubber is selected, so that the conductive silicone rubber is low in price, convenient to process, has certain hardness and is convenient to insert and pull.

In the present embodiment, the side of the tongue 23 facing the upper wall is provided with a pin 24 as an example. As shown in fig. 1 to 4, the conductive member 3 includes a plug section 31 and a pull rod section 32 connected to the plug section 31. The plug section 31 is used for being plugged into the interface end 22, and the pull rod section 32 is used for force application operation of a user. One end of the insertion section 31 departing from the pull rod section 32 is provided with at least two ribs 33 at intervals, at least two ribs 33 are parallel to the extending direction of the pins, and the distance between two adjacent ribs 33 and two adjacent pins 24 is equal. When the plug section 31 is inserted into the interface end 22, the two adjacent ribs 33 are respectively in contact with the two adjacent pins 24 to connect the at least two adjacent pins 24, and at this time, the pin on the MCU of the control board 4 for sensing the USB interface 2 senses the low level of the short circuit of the USB, so as to disconnect the output circuit of the battery element 5 and ensure that the battery element 5 does not output voltage to the external load. When the output of the battery element 3 is disconnected, even if a switch of the power supply device for ignition, including a mechanical switch, an air switch, a touch screen switch, a key switch and the like, is triggered, the battery element cannot output voltage to an external load, and false triggering in the using process can be effectively prevented. As shown in fig. 5, the control board 4 is provided with an airflow sensor 300, and when the output of the battery element 5 is cut off, even if the airflow sensor 300 is successfully triggered, the battery element 5 cannot output voltage to an external load, thereby effectively preventing the device from being triggered by mistake.

In this embodiment, as shown in fig. 4, the number of the ribs 33 may be 2 or more, and the number of the ribs 33 may be smaller than or equal to the number of the pins. For example, the number of the pins is 5, and the number of the ribs 33 may be 2, 3, 4, or 5. Preferably, the number of the ribs 33 is equal to the number of the pins 24, and the ribs correspond to the pins one by one. In this way, each rib 33 correspondingly contacts each pin 24, so that the probability of conduction of the adjacent pins 24 can be improved to the maximum extent, and the probability of error output of the battery element 5 is reduced.

Further, the insertion section 31 is provided with a guide slot 311 adapted to the insertion tongue 23. Since the tongue 23 is located between the upper wall and the lower wall of the casing and the pin 24 is provided on the side facing the upper wall, the bottom wall of the guide slot 311 faces the tongue 23 and the bottom wall of the guide slot 311 is provided with at least two ribs 33. Preferably, the width of the guide slot 311 is adapted to the width of the insert tongue 23. When the inserting section 31 is inserted into the interface end 22, the guiding slot 311 is sleeved on one side of the inserting tongue 23, so that the two side walls of the guiding slot 311 respectively cover the two side walls of the inserting tongue 23 and respectively move along the corresponding side walls to play a role in positioning and guiding, and the convex ribs 33 can be in one-to-one correspondence with the corresponding pins.

Further, a first gap 25 exists between the side of the plug tongue 23 provided with the pin 24 and the upper wall of the casing, and the thickness of the plug section 31 is matched with the first gap 25. When the plug section 31 is inserted into the interface, the plug section 31 is in interference fit with the first gap 25, so that the ribs 33 and the corresponding pins 24 are abutted against each other to form interference electrical contact, thereby ensuring stable electrical connection.

In an embodiment of the present invention, pins 24 are disposed on both sides of the tongue 23, and correspondingly, the insertion section 31 is provided with a jack adapted to the tongue 23, and at least two ribs 33 are disposed on inner walls of the jack respectively. When the inserting section 31 is inserted into the interface end 22, the inserting hole is sleeved on the periphery of the inserting tongue 23, the two inner walls provided with the convex ribs 33 are respectively attached to the upper side and the lower side of the inserting tongue 23, and at least two adjacent convex ribs 33 are electrically contacted with two adjacent pins 24. Preferably, the tongue 23 is in interference fit with the socket to ensure that the rib 33 forms a stable electrical contact with the pin.

In the present exemplary embodiment, the end face of the plug section 31 facing away from the pull rod section 32 is provided with a guide surface 312. The guide surface 312 is inclined relative to the direction of movement of the plug section 31, so that the width of the end of the plug section 31 facing away from the tie section 32 decreases in the direction away from the tie section 32. That is, the width of the end face of the plug section 31 departing from the pull rod section 32 is the smallest, so that the plug section 31 is conveniently aligned with the interface end, and the difficulty of operation is reduced.

In this embodiment, when the conductive member 3 is inserted into the interface end 22, the pull rod segment 32 at least partially protrudes out of the interface end 22, and a user inserts the insertion segment 31 into or removes the interface end 22 by operating the pull rod segment 32. Further, the width of the pull rod section 32 is smaller than the width of the interface end 22, which facilitates the installation of the conductive member 3. In the installation process, the battery element 5 and the control board 4 welded with electronic components such as the USB interface 2 and the sensor can be fastened on the installation support 11, and then the conductive piece 3 is inserted into the interface end 22, so that the output of the power supply element is disconnected in the installation process. Thus, even if the battery element 5 is soldered or electrically contacted to an external load such as the atomizer 200 during the mounting process, it is impossible to output a voltage to the atomizer 200. Finally, the external load, the battery element 5 mounted on the mounting bracket 11, the control board 4 and the conductive piece 3 plugged into the USB interface 2 are plugged into the housing 1 as an assembly from the opening of the second end of the housing 1 until the rod section 32 of the conductive piece 3 protrudes from the clearance hole of the second end. Further, the width of the end of the pull rod section 32 far away from the plug section 31 is gradually reduced along the direction far away from the pull rod section 32, so that a guiding effect is achieved. In practical applications, the tie rod segment 32 may be shaped as a straight strip, a pull ring, or other structure for facilitating force application.

Referring to fig. 8-10, the present invention further provides an aerosol generator, which includes an atomizing device 200 and the power supply device 100 as described above. The atomization device 200 comprises a cover 201, a base 202 and an atomization core 204, wherein one end of the cover 201 is provided with a suction port 206, and the other end of the cover is provided with an opening. The base 202 closes the opening to form a reservoir 203, and the atomizing core 204 is inserted into the base and connected to a suction port 206 to form an atomizing channel 205 extending through the reservoir 203. The oil storage cavity 203 can be pre-stored with tobacco tar, and can be provided with an oil filling hole for self-filling oil by a user. One end of the atomization device 200 is installed in the housing 1, the atomization core 204 is electrically connected with the battery element 5, and the other end extends out of the housing 1 for a user to suck. In practical applications, the atomization device 200 may be detachably mounted on the housing 1, or may be fixed to the housing 1. The lead wire led out from the atomizing core 204 may be electrically connected to the battery element 5 by elastic abutment of a conductive pogo pin, or may be soldered to the battery element 5 by a wire. The specific structure of the power supply device 100 of the aerosol generator refers to the above embodiments, and since the aerosol generator adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

Further, the aerosol generator further comprises an airflow sensor 300. The airflow sensor 300 is electrically connected to the control board 4, and can be used as an air switch for sensing the airflow passing through and generating an electrical signal to be transmitted to the control board 4. The airflow sensor 300 is communicated with the atomization air passage of the atomization device 200. When the user inhales from the suction port 206, the airflow sensor 300 converts the generated negative pressure into an electric signal and transmits the electric signal to the control board 4, and the airflow sensor 300 is activated. Only when the conductive member 3 is removed from the mouthpiece end 22 and the atomizer device 200 is sucked and the airflow sensor 300 is triggered, the battery element 5 outputs a voltage to the atomizer device 200, so that the atomizer device 200 atomizes to generate an aerosol. Neither removal of conductive member 3 from mouthpiece end 22 alone, nor merely pumping on atomization device 200, nor triggering of airflow sensor 300, will cause battery element 5 to output a voltage to atomization device 200. Therefore, the probability of false triggering of the atomizing device 200 can be reduced, the problems that the atomizing core 204 is dried and burnt or oil is heated by mistake and goes bad in the installation, storage and transportation processes of equipment are prevented, and the use safety is improved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
