Specifically, the upper surface of the wireless board is provided with a heat conducting rubber layer.
Specifically, the main body is further provided with a charging port, a power key, an indicator light and a discharging port.
Specifically, heat insulation rubber is arranged between the temperature detection piece and the piezoelectric sensor, and the heat insulation rubber fixedly connects the temperature detection piece with the piezoelectric sensor.
The utility model relates to a wireless precious beneficial effect that charges with foreign matter detects function is, through piezoelectric sensor, can detect whether there is the object on the wireless board, and carry out quality detection to this object, and give controlling means with quality information transfer, controlling means compares the database, can screen out the object of the too big or quality undersize of quality, can detect the temperature variation of object in the charging process on the wireless board through the temperature detection piece, it must be the metallic foreign object to be very fast then this object when the temperature rate of rise, controlling means closes wireless charging device immediately.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the wireless power bank with a foreign object detection function of the present invention;
fig. 2 is a schematic structural diagram of the detection mechanism of the wireless power bank with the foreign matter detection function of the present invention;
in the figure: 1. the wireless power supply comprises a main body, a wireless board 2, a charging port 3, a power key 4, an indicator lamp 5, a discharging port 6, a temperature detection sheet 7 and a piezoelectric sensor 8.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, a wireless charger with a foreign matter detection function comprises a main body 1, a wireless board 2 arranged on the main body 1, and a detection mechanism arranged below the wireless board 2, wherein a storage battery, a wireless charging device and a control device are arranged in the main body 1, and the wireless charging device is fixed below the wireless board 2;
as shown in fig. 2, the detection mechanism includes a temperature detection sheet 7 fixed below the wireless board 2 and a piezoelectric sensor 8 arranged below the temperature detection sheet 7, and the wireless charging device, the temperature detection sheet 7 and the piezoelectric sensor 8 are all electrically connected with the control device.
Specifically, the upper surface of the wireless board 2 is provided with a heat conducting rubber layer. The heat conduction rubber layer can make the roughness of wireless board 2 upper surface increase, prevents that the mobile device from landing from wireless board 2, and heat conduction rubber can be with metallic foreign matter or mobile device's temperature conduction to wireless board 2 in addition, on wireless board 2 conduction to temperature detection piece 7 again.
Specifically, the main body 1 is further provided with a charging port 3, a power key 4, an indicator lamp 5 and a discharging port 6.
Specifically, heat insulation rubber is arranged between the temperature detection sheet 7 and the piezoelectric sensor 8, and the heat insulation rubber fixedly connects the temperature detection sheet 7 and the piezoelectric sensor 8. The heat insulation rubber has the functions of buffering and insulating heat, can buffer the pressure generated by the mobile equipment placed on the wireless board 2, and can prevent the heat on the temperature detection sheet 7 from being conducted to the piezoelectric sensor 8 to prevent the piezoelectric sensor 8 from being damaged.
This wireless precious theory of operation that charges with foreign matter detects function: at first through piezoelectric sensor 8, can detect whether there is the object on wireless board 2, and carry out the quality detection to this object, and give controlling means with quality information transfer, controlling means compares the database, can screen the object of quality too big or quality undersize, wireless charging device work afterwards, wirelessly charge to the object, can detect the temperature variation of object in charging process on the wireless board 2 through temperature detection piece 7, it must be the metallic foreign object to be when very fast then this object of temperature rate of rise, controlling means closes wireless charging device immediately, and because the mobile device also can heat up when charging, when the object temperature rises to predetermineeing early warning temperature, controlling means closes wireless charging device immediately, prevent that mobile device and this wireless treasured that charges from damaging 1 because the temperature is too high.
Compared with the prior art, this wireless treasured that charges with foreign matter detects function, through piezoelectric sensor 8, can detect whether there is the object on the wireless board 2, and carry out quality detection to this object, and give controlling means with quality information transfer, controlling means compares the database, can screen the object of the too big or quality undersize of quality, can detect the temperature variation of object in charging process on the wireless board 2 through temperature detection piece 7, very fast then this object must be the metallic foreign object when temperature rate of rise, controlling means closes wireless charging device immediately.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
