[0036] To facilitate the understanding of the above technical solution of the present invention, the above technical solution of the present invention will be described in detail below through specific usage methods.

[0037] In specific use, a ventilation fan for a motorhome according to the present invention includes a flange connection seat 1, a panel 2 and a top cover 3.

[0038] The flange connection seat 1 is installed with a fan bracket 4 and a motor bracket 5. The fan bracket 4 is installed with a fan motor 6 and a fan blade 7. The motor bracket 5 is installed with a window opening motor 8. The lower end of the window opening motor 8 passes through the panel 2 and is connected to a manual knob 11, and the upper end is connected to a rotating piece 9. The upper port of the rotating piece 9 is provided with a triangular bevel 10.

[0039] Rectangular grooves 23 are provided around the middle of the upper end of the panel 2. A filter screen 12, a grille 13, a light bar 14, a lamp cover 15, a PCB board 16 and a surface mount 17 are respectively installed inside the panel 2. There are sensors on the PCB board 16, and the sensors are one or more of gas sensors for flammable gases such as gas and ethanol, temperature sensors or rain sensors.

[0040] The top cover 3 is installed with a sealing ring 18 at the window and an iron mesh 20 at the front end.

[0041] Mounting holes 22 are provided on both sides of the upper edge of the window of the top cover 3. A window door 19 is installed in the mounting holes 22, and the rotating shaft 21 of the window door 19 can be flipped up and down along the mounting holes 22.

[0042] The bottom of the flange connection seat 1 is installed on the rectangular groove on the panel 2.

[0043] The panel 2 is installed on the inner roof of the motorhome. The top cover 3 is installed on the outer roof of the motorhome.

[0044] The electrical components such as the fan motor 6, the window-opening motor 8, the light strip 14, and the face sticker 17 are all connected to the PCB board 16 and then externally connected to the power cord.

[0045] There are command buttons on the face sticker 17 to turn on the fan motor 6, the window-opening motor 8, the light strip 14, etc. The fan blade 7 can play the role of air replacement.

[0046] The rotation of the window-opening motor 8 drives the rotating piece 9 to rotate. Since the rotating piece 9 is provided with a triangular bevel, the window can be opened and closed at an angle from 0 degrees to 90 degrees. Specifically: when the rotating piece is parallel to the door and window, the door and window are closed; when the rotating piece rotates towards the door and window, the door and window will be pushed open. That is, when the rotating piece rotates 90°, the door and window are just opened 90°. The bevel is set to consider the large contact surface between the rotating piece and the door and window during rotation. If the rotating piece is a right angle, the right-angle tip will press against the door and window during the rotation of the rotating piece, and the door and window will be blocked, resulting in a non-smooth phenomenon. The manual knob 11 can also be manually rotated to open or close the window door in the power-off state.

[0047] The function of the iron net 20 is to prevent mosquitoes and other insects from flying in.

[0048] Specific operation method:

[0049] Conventional mode: Press the start button on the control face sticker 17 switch. The window-opening motor 8 drives the rotating piece 9 to rotate, so that the window door 19 opens. The fan motor 6 rotates, driving the fan blade 7 to rotate for air ventilation. In the power-off state, the manual knob can be manually rotated to open or close the window door 19.

[0050] The sensor on the PCB board 16 on the panel 2 senses flammable gases such as gas and ethanol, and the fan blade 7 will automatically start. The window-opening motor 8 rotates to drive the rotating piece 9 to rotate and open the window door 19 for ventilation; when the temperature sensor sets a certain temperature, when the ambient temperature is higher than the set temperature, the fan blade 7 automatically starts and automatically closes after the temperature drops. When rain is sensed after the ventilator is turned on, it automatically closes.

[0051] In summary, by means of the above technical solutions of the present utility model, by providing a side ventilation opening on the top cover, the PCB board realizes the automatic opening and closing of the window door through the window-opening motor and the rotating piece, and can be used according to the actual environmental changes. The automatic sensing device can prevent the entry of rainwater, and timely discharge toxic and harmful gases or inhale the surrounding air and control the temperature. The product of the present utility model has a simple structure, is easy to use, and has great practical value.

[0052] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
