Description

Technical Field

[0001] This utility model relates to the field of exhaust fans, and in particular to an intelligent control solar-powered exhaust fan. Background Technology

[0002] An exhaust fan, also known as a ventilation fan, is an air conditioning appliance that uses a motor to drive fan blades to rotate and create airflow, exchanging indoor and outdoor air. Exhaust fans utilize air convection to maintain a negative pressure state indoors, forming a suction force that continuously draws in outdoor air and expels hot, stuffy air from inside, thus achieving ventilation, cooling, and other effects. They are widely used in homes and some public places. Currently, exhaust fans are generally quite simple in function, with low levels of intelligence. Most only have simple on / off functions, and their structures are often complex, making them prone to accumulating dust and debris over time, resulting in generally poor ventilation. Utility Model Content

[0003] The purpose of this utility model is to provide a simple and intelligently controlled solar-powered exhaust fan. This exhaust fan includes an upper housing, a lower housing, a solar photovoltaic panel, a support frame, a motor, fan blades, and a controller. The upper housing includes a cover plate. The lower housing is connected below the upper housing, and there is a gap between the upper end of the lower housing and the cover plate. The motor is connected to the lower housing, and the fan blades are connected to the motor. The solar photovoltaic panel is adjustablely connected to the support frame, which is connected above the upper housing. The controller is connected to the inside of the upper housing. The solar photovoltaic panel and the motor are electrically connected to the controller, which is electrically connected to a power plug for connecting to mains power. The controller includes a power module, a temperature control module, and a humidity control module. When the temperature and humidity reach preset values, the power module controls the motor to power on, driving the fan blades to rotate.

[0004] Furthermore, it also includes a wireless remote controller, the controller including a wireless transmission module, the wireless transmission module being adaptable to connect to the wireless remote controller.

[0005] Furthermore, the controller includes a speed adjustment module, which controls the motor rotation speed when the speed button on the wireless remote control is operated.

[0006] Furthermore, the power module includes a solar power module and a mains power module. When the amount of electricity received by the solar photovoltaic panel is greater than the minimum value, the control circuit of the solar power module is connected; when the amount of electricity received by the solar photovoltaic panel is less than the minimum value, the control circuit of the mains power module is connected.

[0007] Furthermore, the controller includes a timing module.

[0008] Furthermore, the bracket is provided with through holes, through which the cables of the solar photovoltaic panels pass and are connected to the controller.

[0009] Furthermore, the upper housing includes a sidewall that extends downward perpendicularly to the cover plate, such that the upper housing covers part of the lower housing, and the controller is connected to the inside of the sidewall.

[0010] Furthermore, the lower housing is connected to the side wall of the upper housing via several connecting pieces.

[0011] Furthermore, the radial dimension of the outer side of the lower housing is smaller than the inner dimension of the side wall of the upper housing, so that when the upper housing is connected to the lower housing, the gap between the upper end of the lower housing and the cover plate connects the gap between the lower housing and the side wall of the upper housing, thus forming a ventilation channel.

[0012] Furthermore, the connecting piece is V-shaped, with the top end of the V-shape connected to the outside of the lower housing, and the two legs of the V-shape arranged at intervals connected to the inside of the side wall of the upper housing.

[0013] This intelligent control solar exhaust fan has the following advantages over existing technologies:

[0014] 1. The controller of this exhaust fan includes a power module, a temperature control module, and a humidity control module. When the temperature and / or humidity reach a preset value, the power module controls the motor to be energized, driving the fan blades to rotate. When the temperature and humidity do not reach the preset value, the exhaust fan does not rotate. Therefore, the exhaust fan can be turned on and off according to the actual indoor temperature and humidity, thereby intelligently regulating the indoor temperature and humidity.

[0015] 2. This utility model exhaust fan includes a wireless remote control, and the controller includes a wireless transmission module, which can be adapted to connect to the wireless remote control. The preset values ​​for temperature and humidity can be modified via the wireless remote control, enabling intelligent on / off operation of the exhaust fan.

[0016] 3. The exhaust fan power module of this utility model includes a solar power module and a mains power module. When the power received by the solar photovoltaic panel is greater than the minimum value, the control circuit of the solar power module is connected; when the power received by the solar photovoltaic panel is less than the minimum value, the control circuit of the mains power module is connected. Thus, when there is sufficient sunlight, the fan is driven by solar energy, and when there is insufficient sunlight, it is driven by mains power, thereby saving energy.

[0017] 4. The upper housing of this utility model exhaust fan includes a side wall that extends downward perpendicularly to the cover plate, allowing the upper housing to partially cover the lower housing and prevent items from falling into the housing. The lower housing is connected to the side wall of the upper housing via several V-shaped connecting pieces. When the upper housing is connected to the lower housing, the gap between the upper end of the lower housing and the cover plate connects the gap between the lower housing and the side wall of the upper housing, forming a ventilation channel. The structure is simple and the ventilation effect is good. Attached Figure Description

[0025] See attached document Figures 1-4 In this embodiment, the up and down directions correspond to the attached... Figure 1 The exhaust fan is normally installed in the vertical extension direction of the installation location. This utility model of an intelligent control solar-powered exhaust fan includes an upper housing 1, a lower housing 2, a solar photovoltaic panel 3, a bracket 4, a motor 5, fan blades 6, and a controller 7. The upper housing 1 includes a cover plate 11. The lower housing 2 is connected to the lower part of the upper housing 1, and there is a gap D between the upper end of the lower housing 2 and the cover plate 11. That is, the upper end of the lower housing 2 and the cover plate 11 are not fitted together; there is a height difference between them in the axial direction, forming the gap D. In this embodiment, the size of the gap D ranges from 2cm to 10cm.

[0026] The motor 5 is connected to the lower housing 2, the fan blade 6 is connected to the motor 5, and the solar photovoltaic panel 3 is angle-adjustably connected to the bracket 4. Specifically, the solar photovoltaic panel 3 is connected to the bracket via a support rod 42. The bracket 4 has multiple fixing holes 43. By connecting the support rod 42 to the fixing holes at different positions, the tilt angle of the solar photovoltaic panel 3 can be adjusted, allowing the exhaust fan to adapt to different usage environments and improve solar energy absorption. The bracket 4 is connected to the upper housing 1. Specifically, the lower end face of the bracket 4 is attached to the cover plate 11 of the upper housing 1. The bracket 4 has several annularly arranged strip grooves 44, and the bracket 4 and the cover plate 11 of the upper housing 1 are connected by bolts. The strip grooves 44 make the connection angle of the bracket 4 relative to the upper housing 1 adjustable. Adjustment is made by rotating the bracket 4 and then fixing the bolts, further allowing the exhaust fan to adapt to different usage environments and improve solar energy absorption.

[0027] In this embodiment, the bracket 4 is provided with a through hole 41, and the cable of the solar photovoltaic panel 3 passes through the through hole 41 and is connected to the controller 7. In this embodiment, the electrical connection end of the solar photovoltaic panel 3 is located on the back of the photovoltaic panel, and the connecting cable is connected from the back of the photovoltaic panel, passes through the through hole 41, and then connects to the controller 7.

[0028] In this embodiment, the upper housing 1 includes a side wall 12, which extends downward perpendicularly to the cover plate 11, allowing the upper housing 1 to cover part of the lower housing, preventing items from falling into the housing. The controller 7 is connected to the inner side of the side wall 12. In this embodiment, the lower housing 2 is connected to the side wall 12 of the upper housing 1 via several connecting pieces 21. In this embodiment, the radial dimension of the outer side of the lower housing 2 is smaller than the inner dimension of the side wall 12 of the upper housing 1, so that when the upper housing 1 is connected to the lower housing 2, the gap between the upper end of the lower housing 2 and the cover plate 11 connects the gap between the lower housing 2 and the side wall 12 of the upper housing 1, forming a ventilation channel. In this embodiment, the connecting piece 21 is V-shaped, with the top of the V-shape connected to the outer side of the lower housing 2, and the two legs of the V-shape spaced apart and connected to the inner side of the side wall 12 of the upper housing. The V-shaped structure allows for a stable gap and secure fixation between the upper and lower housings, ensuring unobstructed ventilation and a stable ventilation effect. In this embodiment, the lower housing 2 includes a mounting plate 22. The mounting plate 22 has several mounting holes near its edge. The mounting plate 22 is located at the lower end of the lower housing 2 and can be fixed in the position to be installed by passing bolts through the mounting holes.

[0029] In this embodiment, the controller 7 is connected to the inside of the upper housing 1. The solar photovoltaic panel 3 and the motor 5 are electrically connected to the controller 7. The controller 7 is electrically connected to a power plug (not shown), which is used to connect to mains power. The controller 7 includes a power module, a temperature control module, and a humidity control module. When the temperature and / or humidity reaches a preset value, the power module controls the motor to power on, driving the fan blades to rotate. In this embodiment, the power module includes a solar power module and a mains power module. When the amount of electricity received by the solar photovoltaic panel is greater than the minimum value, the solar power module control circuit is connected; when the amount of electricity received by the solar photovoltaic panel is less than the minimum value, the mains power module control circuit is connected.

[0030] In this embodiment, the exhaust fan also includes a wireless remote control. The controller 7 includes a wireless transmission module, which can be adapted to connect to the wireless remote control. In this embodiment, the pairing window for the wireless remote control is within 15 seconds after power-on. The operation steps are as follows: Power on the host, then press the pairing button (WiFi icon) on the wireless remote control 5 times. The screen will display a random ID number. Then press the "OFF" button once. Pairing is complete when the screen displays "oo". If it fails, repeat the above operation. Pressing the pairing button as frequently as possible, once per second, can improve the pairing success rate.

[0031] In this embodiment, the controller includes a speed adjustment module. When the speed button on the wireless remote control is operated, the speed adjustment module controls the rotation speed of the motor. Specifically, the wireless remote control has two speed adjustment buttons, "Gear +" and "Gear -", which allow the speed to be adjusted between levels 1 and 5 by pressing the buttons. The wireless remote control also has "ON" and "OFF" buttons. Pressing and holding the "ON" button for 2 seconds turns on the exhaust fan, and pressing the "OFF" button turns off the exhaust fan.

[0032] In this embodiment, the controller includes a timing module. Specifically, the wireless remote control has two timing buttons, "Timer+" and "Timer-", which can be adjusted between 10, 20, 30, 40, 50, 60, 70, 80, 90, and 0 minutes by pressing the timing button. 0 minutes disables the timing function.

[0033] In this embodiment, the minimum voltage for the solar photovoltaic panel to receive electricity is set to 6V. When the voltage is below 6V, the mains power module control circuit is connected, and the device enters standby mode. Preset temperature and humidity trigger values ​​are configured in advance (automatic activation occurs when the environment reaches the preset values). The controller enables intelligent switching between solar and mains power; by default, solar power is prioritized when the device is powered on. The exhaust fan can also be manually turned on via a wireless remote control. If manually turned on, the exhaust fan will not automatically turn off and must be manually turned off via the wireless remote control.

[0034] In this embodiment, temperature triggering and humidity triggering are implemented through a temperature control module and a humidity control module. In temperature triggering mode, the system is set to operate at a specific temperature; once this temperature is reached, the device automatically starts. Setting the temperature to "0" indicates that temperature triggering is disabled. In humidity triggering mode, the system is set to operate at a specific humidity level; once this humidity level is reached, the device automatically starts. Setting the humidity to "0" indicates that humidity triggering is disabled.

[0035] In actual operation, install the exhaust fan mounting plate 22 to the desired location, adjust the installation angle of the solar photovoltaic panel 3 to maximize sunlight reception, and connect the power plug to mains power. Turn on the wireless remote control and pair it with the exhaust fan. Once pairing is complete, it is ready for use.

[0036] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
