Fig. 1-3 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 comprises a main body 1 with a mounting hole 11, a type-C interface 3, a control circuit board 2 and a switching circuit board 4, wherein the control circuit board 2 is installed in the main body 1, and one side of the control circuit board is opposite to the mounting hole 11. The plug end 31 of the type-C interface 3 penetrates through the control circuit board 2 and is inserted into the mounting hole 11 to expose an external structure for plug-in connection, and the pin end 32 of the type-C interface 3 is plugged into the adapter circuit board 4 and is electrically connected with the adapter circuit board 4. The switching circuit board 4 is attached to the other side, deviating from the mounting hole 11, of the control circuit board 2 and is electrically connected with the control circuit board 2. According to the embodiment, the type-C interface 3 penetrates through the control circuit board 2 to be sunk into the control circuit board 2, and the adapter circuit board 4 is electrically connected to the back of the control circuit board 2, so that the installation length of the type-C interface 3 is reduced, the internal space of a power supply device is saved, and the size of equipment is reduced.
In the present embodiment, the main body 1 includes a housing, and a power source, a contact assembly for electrical connection with the atomizer, and the like, which are accommodated in the housing. The control circuit board 2 is accommodated in the housing, and has one side opposite to the mounting hole 11 and the other side opposite to the power supply. That is, a mounting space for mounting the type-C interface 3 is formed between the control circuit board 2 and the mounting hole 11. The typeC interface includes a plug end 31 and a pin end 32. The plug end 31 is provided with an opening for plugging an external structure, and the pin end 32 is provided with a plurality of pins 322 for realizing the functions of quick charging, data transmission, positive and negative plug and other functions. The pin end 32 is electrically connected with the control circuit board 2, and the plug end 31 is inserted into the mounting hole 11, so that the mounting space is mainly used for accommodating the position between the pin end 32 and the plug end 31 of the type-C interface 3, and the length of the type-C interface 3 along the direction from the pin end 32 to the plug end 31 needs to be matched with the mounting space. The present embodiment reduces the installation space by adjusting the length of the type-C interface 3 accommodated in the installation space, thereby achieving the purpose of reducing the size of the power supply device.
Specifically, as shown in fig. 2, the pin end 32 is provided with at least one pin 321, and the pin 321 bends and extends away from the insertion end 31. I.e. the pin 321 is L-shaped, so that the outwardly bent part of the pin 321 can reserve space at the end of the pin end 32 for routing the pin 322. Of course, in practical applications, the pins 321 may be linear, provided that the number of the pins 322 and the layout space are sufficient. Correspondingly, the adapting circuit board 4 is provided with at least one connection hole 41, and the at least one pin 321 is inserted into the corresponding connection hole 41 in an interference manner, so that the type-C interface 3 is fixedly connected with the adapting circuit board 4. Preferably, the cross section of the pin 321 is not circular, and it may be triangular, quadrangular or polygonal, and other irregular shapes. This prevents the smooth surface from causing slippage between the pins 321 and the connection holes 41, which may cause the connection pins 321 to slip out of the connection holes 41 and cause unreliable connection, resulting in the type-C being separated from the adapting circuit board 4. The number of the pins 321 may be 1, 2 or more, and preferably, the number of the pins 321 is 4, and the 4 pins 321 are respectively disposed at 4 corners of the pin end 32, so that the pin end 32 is subjected to uniform force in all directions.
Further, the pin end 32 is provided with at least one positioning post 323, the adapting circuit board 4 is provided with at least one positioning hole 42, and the at least one positioning post 323 is respectively accommodated in the corresponding positioning holes 42. Through the matching of the positioning columns 323 and the positioning holes 42, the relative positions of the type-C interface 3 and the adapter circuit board 4 are firstly determined, so that the pins 321 are accurately inserted into the corresponding connecting holes 41, and the assembly efficiency is improved.
In this embodiment, the pin end 32 is provided with at least one pin 322 at intervals, and each pin 322 correspondingly transmits a signal, so as to implement a corresponding function. The at least one pin 322 is electrically connected to the printed circuit on the adapting circuit board 4, respectively, so as to transmit signals to the control circuit board 2 through the adapting circuit board 4. In practical applications, the at least one pin 322 may be a sheet structure, and correspondingly, the pin is electrically connected to the pads spaced apart from each other on the adapting circuit board 4 by using a patch welding method. The at least one pin 322 may also be a column structure, which may be soldered to the adapting circuit board 4 in an in-line manner.
Further, as shown in fig. 3, one side of the adapting circuit board 4, which is attached to the control circuit board 2, is provided with at least one first bonding pad 43, and correspondingly, the control circuit board 2 is provided with at least one second bonding pad 21 corresponding to the first bonding pad 43. The at least one first bonding pad 43 is electrically connected to the corresponding second bonding pad 21, so that each pin 322 on the pin terminal 32 is electrically connected to the control circuit board 2. Preferably, the first pads 43 are distributed at intervals on the edge of the adapting circuit board 4, and the first pads 43 penetrate through the adapting circuit board 4 to form through holes or through slots. Thus, welding is facilitated, and assembling efficiency is improved.
In this embodiment, the type-C interface 3 may be first assembled on the adapting circuit board 4 to form a component, and then the component is integrally assembled on the control circuit board 2. Namely, the plug terminal 31 of the type-C interface 3 is inserted through the control circuit board 2 from the side of the control circuit board 2 away from the mounting hole 11 until the plug terminal is inserted into the mounting hole 11. At this time, the relay circuit board 4 may be attached to a side of the control circuit board 2 away from the mounting hole 11. Finally, the second land 21 and the third land are soldered to fix the relay circuit board 4 and the entire assembly to the control circuit board 2. Correspondingly, the control circuit board 2 is provided with a position-avoiding hole 22 for the insertion end 31 to pass through, and the pin end 32 is accommodated in the position-avoiding hole 22, so that the shape of the position-avoiding hole 22 is matched with that of the pin end 32. That is, the clearance hole 22 includes a clearance space through which the at least one pin 321 passes.
In the embodiment, the pin end 32 of the type-C interface 3 is sunk into the avoiding hole 22 of the control circuit board 2, so that the occupation of the type-C interface 3 on the installation space in the length direction is reduced, and the reduction of the required reserved distance between the control circuit board 2 and the installation hole 11 is facilitated. Further still add switching circuit board 4 and switch on type-C interface 3 and control circuit board 2, and set up switching circuit board 4 in the one side that control circuit board 2 deviates from mounting hole 11, thereby shift the produced back that highly shifts to control circuit board 2 of welding type-C interface 3 among the prior art, make welding height also not occupy installation space, further reduced the distance between control circuit board 2 and the mounting hole 11, make the installation space that installation type-C interface 3 required reduce to 5-6mm from current about 10mm, the very big inner space who has saved equipment, be favorable to reducing the equipment size.
