For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] Please refer to Figures 1-5 , which is a schematic diagram of the preferred embodiment of the power supply device of the aerosol generator. The power supply device 100 includes a shell 1, a control board 4, a battery element 5, a USB interface 2 and a conductive part 3. The control board 4 and the battery element 5 are both installed in the shell 1, and the control board 4 is electrically connected with the battery element 5. The pin end 21 of the USB interface 2 is welded to the control board 4, and the interface end 22 penetrates the shell 1 for power contact. The conductive part 3 is adapted to the interface end 22. When the conductive part 3 is plugged into the interface end 22, the control board 4 receives the first electrical signal that the USB interface 2 is short-circuited, and turns off the output of the battery element 5, so that the battery element 5 is disconnected with the external load. When the conductive part 3 is taken out of the interface end 22, the control board 4 receives the second electrical signal that the USB interface 2 is not short-circuited, and turns on the output of the battery element 5, so that the battery element 5 is electrically connected with the external load. In this embodiment, by plugging the conductive part 3 into the USB interface 2, the output circuit of the battery element 5 is turned on and off, the output of the battery element 5 is effectively controlled, and the probability of false output of the battery element 5 of the aerosol generator is reduced.

[0037] In this embodiment, as Figure 3 and Figure 5As shown, the shell 1 is a hollow structure, the first end of which is loaded with a mounting bracket 11 for mounting electronic components such as the control board 4, battery element 5, USB interface 2, etc. The second end of the mounting bracket 11 opposite to the shell 1 encloses a mounting slot 12 for mounting external loads. The opening of the second end is the opening of the mounting slot 12. The first end of the shell 1 corresponds to the interface end 22 and is provided with a clearance hole, through which the interface end 22 is exposed outside the shell 1 for plugging. The control board can adopt a printed circuit board and be provided with various required components such as MCU, switch, charge protection circuit, air flow sensor, etc. The USB interface 2 includes a sleeve and a base, the base of which is provided with a plug-in tongue 23, and a plurality of pins 24 are arranged on the plug-in tongue 23 at intervals. The base is mounted on the opening of one end of the sleeve and closes the opening to form a pin end 21. Correspondingly, the opening of the other end of the sleeve is not provided with the base, thus forming an interface end 22 for plugging. The base and / or the sleeve are provided with fixing feet, by which the USB interface 2 is fastened to the control board 4, and the plurality of pins 24 are respectively electrically connected to the corresponding pins of the MCU on the control board 4. The plug-in tongue 23 extends in the direction from the pin end 21 to the interface end 22. The inner wall of the sleeve includes an upper wall and a lower wall respectively located on the upper and lower sides of the base, and two side walls respectively located on the left and right sides of the base. The plug-in tongue 23 is arranged parallel to the upper and lower walls and perpendicular to the two side walls. The plug-in tongue 23 can be attached to the upper wall or the lower wall, or can be located between the upper wall and the lower wall and have a gap with the upper wall and the lower wall respectively.

[0038] Further, the pins 24 can be arranged on one side of the plug-in tongue 23 towards the upper wall, or on one side of the plug-in tongue 23 towards the lower wall, or of course can be distributed on both sides of the plug-in tongue 23. The number of the plurality of pins 24 can be 2, 3, 4, 5 or more, and each pin 24 can define a function. In this embodiment, as shown in the figure, the pins 24 are arranged on one side of the plug-in tongue 23 towards the upper wall, and each pin 24 defines a function. Figure 6 and Figure 7As shown, the IO pin in the MCU for detecting the USB interface 2 is configured in a pull-up mode, which can be pulled up to a high level by a resistor inside the chip or by adding a pull-up resistor in the circuit. The high level is the working voltage, and the data read from the program of the IO pin is 1. That is, when the interface end 22 of the USB interface 2 is normally plugged with an external power supply 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 read from the pin in the program is 0. At this time, the MCU transmits an electrical signal to disconnect the output of the battery element 5. The conductive part 3 corresponds to the position of the plug 23 in structure, can be plugged into the interface end 22, and short-circuits the USB interface 2. The conductive part 3 is made of conductive material. Preferably, it is made of conductive silica gel, which is low in price, convenient to process, and has a certain hardness, facilitating plugging and unplugging.

[0039] In this embodiment, the plug 23 is taken as an example, which is provided with a pin 24 on the side facing the upper wall. As shown in Figures 1-4 The conductive part 3 includes a plug-in section 31 and a pull rod section 32 connected to the plug-in section 31. The plug-in section 31 is used for plugging into the interface end 22, and the pull rod section 32 is used for user force operation. At least two protrusions 33 are provided at the end of the plug-in section 31 away from the pull rod section 32, which are parallel to the extension direction of the pins 24, and the distance between adjacent two protrusions 33 and adjacent two pins 24 is equal. When the plug-in section 31 is plugged into the interface end 22, adjacent two protrusions 33 are in contact with adjacent two pins 24, respectively, to turn on at least two adjacent pins 24. At this time, the pin on the MCU of the control board 4 for sensing the USB interface 2 senses a low level that the USB is short-circuited, so as to disconnect the output circuit of the battery element 5, and ensure that the battery element 5 cannot output voltage to the external load. When the output of the battery element 5 is disconnected, even if the switch for ignition of the power supply device, including a mechanical switch, an air switch, a touch screen switch, and a key switch, is triggered, the battery element cannot output voltage to the external load, which can effectively prevent the device from being triggered by mistake in use. Figure 5 As shown in

[0040] In this embodiment, as Figure 4As shown, the number of the protrusions 33 can be two or more, and the number of the protrusions 33 can be less than or equal to the number of the pins. For example, the number of the pins is five, and the number of the protrusions 33 can be two, three, four or five. Preferably, the number of the protrusions 33 is equal to the number of the pins 24, and one-to-one correspondence. In this way, each protrusion 33 corresponds to each pin 24, which can maximize the probability of adjacent pins 24 being conducted, thereby reducing the probability of battery element 5 misoutput.

[0041] Further, the plug-in section 31 is provided with a guide slot 311 which is adapted to the plug-in tongue 23. Since the plug-in tongue 23 is located between the upper wall and the lower wall of the sleeve, and the pins 24 are provided on the side towards the upper wall, the bottom wall of the guide slot 311 is towards the plug-in tongue 23, and the bottom wall of the guide slot 311 is provided with at least two protrusions 33. Preferably, the width of the guide slot 311 is adapted to the width of the plug-in tongue 23. When the plug-in section 31 is inserted into the interface end 22, the guide slot 311 is sleeved on one side of the plug-in tongue 23, so that the two side walls of the guide slot 311 respectively cover the two side walls of the plug-in tongue 23 and move along the corresponding side walls, thereby playing a positioning and guiding role, so that each protrusion 33 can correspond to the corresponding pin one by one.

[0042] Further, the plug-in tongue 23 is provided with a first gap 25 between one side of the pin 24 and the upper wall of the sleeve. The thickness of the plug-in section 31 is adapted to the first gap 25. When the plug-in section 31 is inserted into the interface, the plug-in section 31 is interference fit with the first gap 25, so that the protrusions 33 and the corresponding pins 24 are in interference contact, thereby ensuring stable electrical connection.

[0043] In an embodiment of the present application, the plug-in tongue 23 is provided with pins 24 on both sides, and the plug-in section 31 is provided with a plug hole which is adapted to the plug-in tongue 23. The inner wall of the plug hole is provided with at least two protrusions 33. When the plug-in section 31 is inserted into the interface end 22, the plug hole is sleeved on the outer periphery of the plug-in tongue 23, and the two inner walls provided with the protrusions 33 are respectively attached to the upper and lower sides of the plug-in tongue 23, and at least two adjacent protrusions 33 are in electrical contact with two adjacent pins 24. Preferably, the plug-in tongue 23 is interference fit with the plug hole, so as to ensure that the protrusions 33 and the pins form stable electrical contact.

[0044] In the embodiment, the end face of the plug-in section 31 away from the pull rod section 32 is provided with a guide surface 312. The guide surface 312 is inclined relative to the moving direction of the plug-in section 31, so that the width of the end of the plug-in section 31 away from the pull rod section 32 gradually decreases in the direction away from the pull rod section 32. That is, the width of the end of the plug-in section 31 away from the pull rod section 32 is the smallest, which facilitates the alignment of the plug-in section 31 with the interface end and reduces the difficulty of operation.

[0045] In the embodiment, when the conductive member 3 is inserted into the interface end 22, the pull rod section 32 at least partially extends out of the interface end 22, and the user inserts or takes out the plug-in section 31 from the interface end 22 by operating the pull rod section 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, the control board 4 on which the electronic components such as the USB interface 2 and the sensor are welded, and the like are first fastened to the mounting bracket 11, and then the conductive member 3 is inserted into the interface end 22, so that the disconnection of the output of the power supply element in the installation process is realized. In this way, in the installation process, even if the battery element 5 is welded or electrically connected with the external load such as the atomization device 200, the voltage cannot be output to the atomization device 200. Finally, the external load, the battery element 5 mounted on the mounting bracket 11, the control board 4, and the conductive member 3 inserted into the USB interface 2 are inserted into the shell 1 as a whole through the opening of the second end of the shell 1, until the pull rod section 32 of the conductive member 3 extends out of the avoiding hole of the second end. Further, the width of the end of the pull rod section 32 away from the plug-in section 31 gradually decreases in the direction away from the pull rod section 32, which plays a guiding role. In actual application, the shape of the pull rod section 32 can be a straight bar, a pull ring, or other structures facilitating force application.

[0046] Please refer to Figures 8-10The application further provides an aerosol generator comprising the power supply device 100 as described in any of the above embodiments and an atomization device 200. The atomization device 200 comprises a cover 201, a base 202 and an atomization core 204. The cover 201 is provided with a suction port 206 at one end and an opening at the other end. The base 202 closes the opening to form an oil storage cavity 203. The atomization core 204 is inserted into the base and connected to the suction port 206 to form an atomization channel 205 extending through the oil storage cavity 203. The oil storage cavity 203 can be pre-stored with tobacco tar or provided with an oil injection hole for user to inject oil. The atomization device 200 is mounted at one end in the shell 1 and the atomization core 204 is electrically connected to the battery element 5, and the other end extends out of the shell 1 for user to smoke. In actual application, the atomization device 200 can be detachably mounted in the shell 1 or fixed in the shell 1. The lead wire from the atomization core 204 can be electrically connected to the battery element 5 through the elastic abutment of the conductive elastic needle or welded to the battery element 5. The specific structure of the power supply device 100 of the aerosol generator is referred to the above embodiments. Since the aerosol generator adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described here.

[0047] 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 and generating an electrical signal transmitted to the control board 4. The airflow sensor 300 is connected to the atomization airway of the atomization device 200. When the user inhales from the suction port 206, the airflow sensor 300 converts the negative pressure generated into an electrical signal and transmits it to the control board 4, and at this time the airflow sensor 300 is triggered. Only when the conductive part 3 is taken out of the interface end 22 and the atomization device 200 is smoked and the airflow sensor 300 is triggered, the battery element 5 outputs voltage to the atomization device 200, so that the atomization device 200 atomizes to generate aerosol. Only taking the conductive part 3 out of the interface end 22 or only smoking the atomization device 200 to trigger the airflow sensor 300 cannot make the battery element 5 output voltage to the atomization device 200. In this way, the probability of the atomization device 200 being mistakenly triggered can be reduced, and problems such as dry burning of the atomization core 204 or deterioration of the oil due to mistaken heating of the oil during installation, storage and transportation of the equipment can be prevented, thereby improving the safety of use.

[0048] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
