[0020] Figure 2 yes Figure 1 A magnified view of a portion of the image;

[0021] Figure 3 This is a partial sectional view of the mounting support frame of this utility model. Detailed implementation method:

[0022] For example, see below. Figures 1 to 3As shown, a solar-powered roof ventilator includes a roof ventilator body 10 installed on the roof. A mounting support frame 20 is fixed to the top surface of the roof where the roof ventilator body 10 is located, and a solar photovoltaic panel 30 is fixed to the top of the mounting support frame 20.

[0023] The solar photovoltaic panel 30 is located directly above and covers the roof fan body 10.

[0024] Furthermore, the roof fan body 10 includes a base 12, which is fixed to the top surface of the roof and covers the ventilation channel formed on the roof (wherein, a fire damper can be fixed at the base 12, and the attached figure shows that the fire damper is not installed). An upwardly arc-shaped extension sleeve 121 is formed on the inner side wall of the through hole in the middle of the top plate of the base 12.

[0025] Multiple support plates are fixed around the central through hole on the top surface of the top plate of the base 12. The air duct 11 is located above the base 12. The top surfaces of all the support plates are fixed to the bottom surface of the top plate of the air duct 11. A motor 13 is fixed in the middle of the top surface of the top plate of the air duct 11. The bottom end of the output shaft of the motor 13 extends out of the bottom surface of the top plate of the air duct 11 and is fixed with an impeller 14. The impeller 14 faces the top of the extension sleeve 121.

[0026] The four vertical support columns at the bottom of the mounting support frame 20 are fixed to the front and rear roofs on the left and right sides of the roof fan body 10.

[0027] A horizontal windbreak plate 21 is fixed between the lower parts of the four vertical support columns. A central main through hole 22 is formed in the middle of the horizontal windbreak plate 21. The wind duct 11 of the roof fan body 10 is inserted into the central main through hole 22.

[0028] Furthermore, an annular sealing ring 23 is fixed to the top surface around the central main through hole 22 of the horizontal wind deflector 21, and the inner wall of the annular sealing ring 23 is close to the outer wall of the wind duct 11 of the roof fan body 10. This annular sealing ring 23 and the horizontal wind deflector 21 can prevent the air drawn from the house from blowing upward onto the solar photovoltaic panels 30 above, and instead discharge it to the left and right.

[0029] Furthermore, a filter sleeve 24 is fixed to the bottom surface of the horizontal windbreak plate 21 around the central main through hole 22, and the base 12 of the roof fan body 10 and the air duct 11 below the central main through hole 22 are inserted into the filter sleeve 24.

[0030] The bottom end of the filter sleeve 24 presses against the top surface of the roof. This filter sleeve 24 can prevent external insects and birds from entering the central through-hole of the air duct 11 or the base 12, thus providing protection.

[0031] Furthermore, a protective cover 15 is fixed on the top surface of the top plate of the air duct 11, and the motor 13 is located in the protective cover 15.

[0032] The protective cover 15 has multiple ventilation holes 151 formed on the top plate of the side plate. The filter screen 152 is fixed to the outer side wall of the side plate and the top surface of the top plate of the protective cover 15 and covers the corresponding ventilation holes 151.

[0033] Meanwhile, upper wind deflectors 2 are fixed to the four side walls of the mounting support frame 20 below the solar photovoltaic panel 30. The bottom surface of the upper wind deflector 2 is lower than the middle of the protective cover 15 or the bottom surface of the protective cover 15.

[0034] This structure allows the heat from the motor 13 to dissipate through the ventilation holes 151 of the protective cover 15, while the wind deflector 2 and solar photovoltaic panel 30 on top can prevent external wind and rain from directly hitting the roof fan body 10, so that water will basically not enter the protective cover 15, ensuring the normal operation of the motor 13.

[0035] In this embodiment, the solar photovoltaic panel 30 is connected to a battery via a photovoltaic controller, and then the battery is electrically connected to an inverter. The inverter converts direct current (DC) into alternating current (AC) to power the rooftop fan 10, achieving environmentally friendly power supply (the battery, inverter, and other components are all located at the control unit, which is a conventional structure and is not shown in the attached drawings). The electrical connection method of the solar photovoltaic panel 30 and the use of control circuits are all conventional structures and will not be described in detail here.

[0036] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
