Description

Technical Field

[0001] This utility model belongs to the technical field of fan control equipment, specifically relating to a fan constant speed regulation device. Background Technology

[0002] As a key component in industrial and civil combustion systems, fans are widely used in boilers, stoves, water heaters, and other equipment. Their operating status directly affects the efficiency and safety of gas combustion. In traditional combustion systems, fans typically rely on simple on / off control or operate at a fixed speed, unable to dynamically adjust their output based on changes in gas input pressure or operating conditions. This fixed mode not only easily leads to incomplete combustion and energy waste but may also cause safety hazards such as backfire and flameout.

[0003] While some existing wind turbine speed control devices possess certain speed regulation capabilities, most suffer from complex structures, slow control response, or reliance on complex external control systems, making them inconvenient to use and resulting in high installation and maintenance costs. Furthermore, existing equipment commonly suffers from rudimentary human-machine interfaces, low adjustment precision, and inconvenient mode switching in practical use.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0018] like Figures 1 to 3As shown, a fan speed control device includes a control board 10 and a mounting housing 20. The mounting housing 20 has a recessed mounting groove 21, the size of which is larger than the size of the control board 10. The control board 10 is installed inside the mounting groove 21. During operation, power is input to the control board 10. The control board 10 collects data in real time based on changes in gas source pressure and uses the maximum pressure value as a reference to achieve constant-speed operation control of the fan. Furthermore, the control board 10 is externally connected to a valve speed controller, which automatically adjusts the fan output airflow according to the input gas pressure to achieve a reasonable match between gas and airflow, ensuring the stability and energy efficiency of the combustion process.

[0019] In practical implementation, the lower surface of the control panel 10 is provided with a button mounting surface 11. A switch button 111, a mode button 112, and a power button 113 are respectively mounted on the surface of the button mounting surface 11. The switch button 111, the power button 113, and the mode button 112 are arranged sequentially. The power button 113 includes a high-power button 113a and a low-power button 113b, used to control the fan output power by increasing and decreasing the output power. During use, the user can control the power on / off state of the device by pressing the switch button 111; switch different operating modes by using the mode button 112; and adjust the fan output airflow by using the high-power button 113a or the low-power button 113b, thereby achieving rapid adjustment of the gas combustion intensity to meet the usage needs under different working conditions. The switch button 111, the mode button 112, and the fire button 113 are electrically connected to the control circuit of the control board 10. The input signals are identified and processed through the built-in program logic, and combined with the air source pressure value and preset parameters, the corresponding control signals are output to the fan motor or air valve adjustment module to realize the constant speed regulation control function of the fan.

[0020] In practical implementation, the switch button 111, the mode button 112, and the fire button 113 can be tactile buttons or touch buttons. In addition to basic control functions, these buttons can also be used to collect maximum and minimum pressure signals during operation. The control board 10 dynamically monitors and records this pressure data, and, in conjunction with different button input commands, achieves precise adjustment of the gas-air ratio, thereby optimizing combustion efficiency, ensuring more complete gas combustion, and ensuring the airflow output better matches usage requirements, thus improving the overall energy efficiency and stability of the system.

[0021] In practical implementation, the lower surface of the mounting housing 20 is provided with a switch through hole 22, a mode through hole 23, a high flame through hole 24, and a low flame through hole 25, which are arranged sequentially. The end of the switch button 111 protrudes through the switch through hole 22, the end of the mode button 112 protrudes through the mode through hole 23, the end of the high flame button 113a protrudes through the high flame through hole 24, and the end of the low flame button 113b protrudes through the low flame through hole 25. In use, the user can control the fan device, switch operating modes, and adjust the wind speed by pressing the above buttons. Because the buttons protrude from the housing surface, they have good human-machine interaction and are easy to identify and operate.

[0022] In practical implementation, a control chip 12 is mounted on the upper surface of the control board 10 to realize core functions such as fan speed regulation, constant speed control, and signal processing. The upper edge of the control board 10 is equipped with a power connection port 13, a speed controller connection port 14, a constant speed connection port 15, and a fan connection port 16, respectively used to connect the power input module, external speed controller, constant speed controller, and fan actuator. During use, power is input to the control board 10 through the power connection port 13. The control chip 12 receives control signals from the speed controller connection port 14 and the constant speed connection port 15, processes the data according to the set logic, and outputs the corresponding drive signal to the fan connection port 16, thereby realizing fan start / stop control, speed regulation, and operating state switching, improving safety.

[0023] In practical implementation, the inner side of the mounting groove 21 is provided with a fixing post 211, and the surface of the control plate 10 is provided with a fixing hole 17. The fixing hole 17 corresponds to the fixing post 211, and is connected and fixed to the fixing post 211 by fasteners passing through the fixing hole 17, thereby fixing the control plate 10 inside the mounting housing 20. The structure is simple and the installation is convenient.

[0024] In summary, the lower surface of the control board 10 is provided with a button mounting surface 11. A switch button 111, a mode button 112, and a power button 113 are respectively mounted on the surface of the button mounting surface 11. These buttons can be tactile or touch buttons. A control chip 12 is mounted on the upper surface of the control board 10. A power connection port 13, a speed controller connection port 14, a constant speed connection port 15, and a fan connection port 16 are respectively mounted on the edge of the upper surface of the control board 10. The fan constant speed control device of this utility model has a compact structure and rich functions. It can dynamically adjust the fan output according to the gas source pressure and gas input, improving combustion efficiency.
