Description of the Invention: [Technical Field of the Invention] The present invention particularly relates to a solar exhaust technology that makes an external battery an optional device and can ensure the service life of the motor. [Prior Art], China's invention patent No. 1308419 "Solar heat dissipation device for houses" The first picture reveals the most traditional roof ventilation device. As described in the specification of this patent, such a traditional roof ventilation device has a ventilation row. The disadvantages of poor gas and cooling effects. Therefore, there is an invention of the second to seventh embodiments of the patent, which mainly includes a solar wafer 31, and a motor 22 that can actuate the fan 23 to operate. When the solar panel 31 absorbs solar energy, it can The solar light energy is converted into electrical energy for the motor 22, which in turn drives the fan 23 to rotate to produce a flowing gas stream that acts on the plurality of blades n of the ventilator 1 to rotate the ventilator 10 to form another flowing gas stream. However, the patent still has the following disadvantages: 1. The solar panel 31 can directly supply the converted electric energy to the design of the motor, and the output voltage is unstable, so that the failure rate of the motor 22 is extremely high, and the ventilation is high. When the heat sink is installed in the house and environment, the maintenance is quite difficult; therefore, it is better to reduce the failure rate of the motor 22 through the intermediary or parallel connection of a battery. However, the battery cannot withstand high temperature and volume. The disadvantage of the big b, so it can not be installed to the roof with the ventilation heat sink, and the battery must be installed in the house through the connection of the line. It is 201144719. In the most reasonable state, the battery is a module. The necessary components of the configuration, resulting in high cost of installation and assembly. 2. Since the motor 22 is mounted below the fan 23, the motor 22 may be retarded or reduce the flow of air through 'making the fan 23 less plentiful, so as to detract from the fan 23's exhaust performance'. In addition, the motor 22 and the solar chip 31 are connected. The wire 33' will be exposed, except for the overall appearance, and it is easy to fall off. Lu 3·the solar panel 31 has to be fixed by erecting a tripod 32, and the ventilator 10 is required to be self-rotating, and the assembly structure is quite complicated' and when the motor affects the fan exhausting performance, The improvement of the ventilation function of the ventilator 1 实 is quite limited, so it is not economically beneficial. In view of the above-mentioned patent cases, the inventors have actively studied and researched, and after many trials and improvements, finally developed the present invention which has practical effects. SUMMARY OF THE INVENTION The present invention is directed to: providing a solar exhaust fan comprising: a base having an inner bore extending through the upper and lower air ducts; and a set of seats disposed on the base having a guide a cover plate directly above the air duct, and a hat sill extending downward along the outer periphery of the cover plate, so that a slat-shaped flow path for preventing rainwater from entering is formed between the cover plate, the visor and the top end of the air guide tube; The corresponding ring is disposed on the braided flow path between the top end of the air duct and the cover plate; a motor fixed to the seat; 201144719 A fan is installed under the motor and in the braided flow path so that it can be a motor driven; a solar wafer directly mounted on the top surface of the cover plate; and a controller assembled to the socket for receiving the solar wafer to absorb the electrical energy emitted by the solar energy, the controller having at least one The voltage stabilizing circuit enables it to process the electric energy* to actuate the motor, and force the air to flow in the inner hole of the air duct and the meandering flow path.

Can provide battery (9 〇) charging, or directly convert to the required DC power preset value, and can be used by the exhaust fan, thereby forming a second power supply circuit, in order to meet the needs of the sun light source or nighttime use Expand the scope of use. As described above, the present invention has the advantages of ensuring the service life of the motor, making the external battery suitable for use, not detracting from the fan exhausting performance, the wires are not exposed, and the structure is more compact, compared with the currently known solar exhaust fan. The advantage is a rather outstanding and excellent design, and it is not found in the publication or public use, and is in combination with the application requirements of the invention patent. However, the above description is only a preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention should still be covered by the present invention. Within the scope. 10 201144719 [Simple description of the drawings] The first figure is an exploded view of the solar wafer and the socket of the present invention.
