[0019] The utility model will be further described below in combination with the drawings and specific embodiments.
[0020] As Figure 1 , Figure 2 And Figure 3 As shown in the utility model electronic cigarette charger, including shell 1, the inside of shell 1 is hollow, shell 1 is mainly used for installing and protecting each part, the side of shell 1 is equipped with the charging position for electronic cigarette insertion, electronic cigarette is equipped with magnet, for starting electronic cigarette charger.
[0021] The shell 1 is provided with a charging electrode 2 and a power plug 3, and the shell 1 is provided with a PCBA main board 4, a Hall switch 5, a single-chip microcomputer, a MOS tube, a power module 6, and an output module 7. The single-chip microcomputer, the MOS tube, the power module 6, and the output module 7 are all mounted on the PCBA main board 4. The PCBA main board 4 is used to realize the power supply and signal connection between the single-chip microcomputer and each module.
[0022] The charging electrode 2 is located at a charging position, the power plug 3 is used to connect a 220V power supply, the power module 6 is used to convert the 220V alternating current connected by the power plug 3 into 5V direct current, and the 5V direct current is used to supply power to each module and an electronic cigarette. The output module 7 is used to output the 5V direct current through the charging electrode 2, the Hall switch 5 is used to sense a magnetic field and output a level signal, and the single-chip microcomputer controls the opening and closing of the output module 7 according to the level signal of the Hall switch 5.
[0023] Specifically, the Hall switch 5 is arranged on one side of the charging electrode 2. When the Hall switch 5 senses the approach of a magnetic field, the Hall switch 5 outputs a high-level signal. The single-chip microcomputer detects the high-level signal, thereby opening the MOS tube to output a DC 5V power supply to charge the electronic cigarette. When the magnet on the electronic cigarette (i.e., the electronic cigarette) moves away from the charging position, the Hall switch 5 cannot sense the magnetic field, and the Hall switch 5 outputs a low-level signal. The single-chip microcomputer detects the low-level signal and immediately closes the MOS tube to stop outputting the DC 5V power supply.
[0024] The shell 1 is provided with an indicator light 8, and the PCBA main board 4 is provided with a display module 9. The display module 9 is used to control the state of the indicator light 8.
[0025] The shell 1 is further provided with a PCBA secondary board 10. The PCBA secondary board 10 is connected to the PCBA main board 4 through a connecting line 11. The charging electrode 2 and the Hall switch 5 are both connected to the PCBA secondary board 10. The PCBA secondary board 10 is used to realize the switching of the charging electrode 2 and the Hall switch 5.
[0026] The shell 1 is provided with a clamping plate 12 for fixing the PCBA main board 4 and a mounting column 13 for fixing the PCBA secondary board 10.
[0027] When the electronic cigarette needs to be charged, it is inserted into the charging position of the shell 1. The electronic cigarette and the shell 1 have a magnet and a Hall switch 5 at the corresponding positions, respectively. When the Hall switch 5 senses the magnetic field, the switch is opened, and the charging electrode 2 outputs a charging current. When the product is fully charged, the output module 7 detects the low current and disconnects the output.
[0028] The traditional mechanical switch in the electronic cigarette charger can be accidentally started for various reasons (such as vibration, accidental touch, etc.), resulting in unnecessary power consumption and even safety hazards. The charger of the embodiment starts the charging process only when a specific action or condition (such as the user inserting the electronic cigarette for charging) is sensed through the Hall switch, thereby avoiding the risk of accidental triggering. In addition, the Hall switch has the characteristics of low power consumption, and can maintain very low power consumption when not working, further prolonging the service life and battery endurance time of the electronic cigarette charger.
[0029] The utility model is not limited to the above optional implementation, and anyone can derive other various forms of products under the enlightenment of the utility model, but no matter any change in its shape or structure, any technical scheme falling within the scope defined by the claims of the utility model falls within the protection scope of the utility model.
