Because the power interface of the current vehicle-mounted charger is generally arranged at the central armrest of the automobile, and the water cup is also arranged at the central armrest, when people in the automobile drink water, water in the water cup may drop onto the vehicle-mounted charger, and then water flows into the vehicle-mounted charger through the charging interface, so that the circuit board 21 in the vehicle is damaged due to short circuit. The bottom of the charging interface on the circuit board 21 is wrapped by the water storage box 4, when external water enters through the charging interface, water flow flows downwards along the inner wall of the water storage box 4 and flows downwards through the groove in the thermistor 42 and then flows to the bottom of the water storage box 4, because the bottom of the water storage box 4 is fixedly connected with the electrode plates 41, and the number of the electrode plates 41 is two, the two electrode plates 41 form a closed loop under the connection effect of the water flow, so that the heating plate 34 is electrified and started, the heating plate 34 dries a small amount of water at the bottom of the water storage box 4 by using the emitted heat, the electrode plates 41 are automatically disconnected, normal charging of electronic equipment is ensured, meanwhile, the heating plate 34 dries elements on the circuit board 21 by using waste heat, and the probability of short circuit of internal elements due to dampness is reduced.
Example three:
as shown in fig. 3-5, in the present embodiment, the problem that water is more supplied to the vehicle-mounted charger during the use process is solved. If a person in the vehicle carelessly turns over the water cup or the water cup with an opening is suddenly braked, a large amount of water in the water cup is spilled, so that the accident that the water enters the vehicle-mounted charger more, and the like is caused, at the moment, water flows into the water storage box 4 along the charging interface, as shown in fig. 5, a baffle is fixedly connected in the water storage box 4 and above the lead 43, and the water can be prevented from leaking out of the connecting position between the lead 43 and the inner wall of the water storage box 4; according to the second embodiment, the electrode plate 41 in the water storage box 4 forms a closed loop, so that the heating plate 34 starts to heat water in the water storage box 4 for drying, water in the water storage box 4 enters more water, and the water storage box cannot be dried quickly, the internal temperature of the water storage box 4 gradually rises, and then the thermistor 42 in the water storage box 4 is reduced by the thermistor, so that the magnetic force of the electromagnet in the buffer plate 32 is increased, the support rod 33 is pushed to move, the vehicle-mounted charger is pushed out from the power interface quickly, the power supply in the vehicle-mounted charger is cut off, the internal short circuit of the vehicle-mounted charger is prevented from being caused by excessive water, and further, in combination with the second embodiment, the vehicle-mounted charger can automatically carry out intelligent power-off protection according to the water volume, the normal charging of electronic equipment is guaranteed, and the internal safety of the vehicle-mounted charger is also protected.
Example four:
as shown in fig. 1, in this embodiment, if the service life of the vehicle-mounted charger is too long, when an aging short circuit occurs to electronic components on the circuit board 21 in the protective shell 1, the temperature inside the protective shell 1 will rise rapidly, so that the temperature of the thermistor 42 in the water storage box 4 rises, the internal structure of the thermistor 42 starts to decrease, the internal current of the second electromagnet in the buffer plate 32 starts to increase, and an effect of increasing magnetic force is generated, then the second electromagnet pushes the support rod 33 to move by means of magnetic force, and the vehicle-mounted charger is ejected out from the power interface, so that the internal part of the vehicle-mounted charger is prevented from being continuously powered on, and the automobile power interface is prevented from being burnt.
Example five:
as shown in fig. 3, in this embodiment, the buffer plate 32 in the power-off assembly 3 is fixedly connected to the support plate 31, and the buffer plate 32 is preferably a polystyrene foam plate as a main material and has good shock-resistant and flame-retardant properties, so that the anti-falling performance of the vehicle-mounted charger can be effectively enhanced through the buffer plate 31, and the service life of the vehicle-mounted charger is prolonged; meanwhile, the upper part of the inside of the water storage box 4 is narrow and the lower part of the inside of the water storage box 4 is wide, so that the thermistor 42 is fixed, the water storage box 4 is made of hard plastic, and good insulation and flame retardance are achieved, so that transition fit is performed between the thermistor 42 and the water storage box 4, the thermistor 42 is convenient to take down in the later period, and the installation stability of the thermistor 42 is improved.
