Description

Technical Field

[0001] This utility model relates to the field of control system technology, specifically to a wind-oil linkage control mechanism. Background Technology

[0002] The air-fuel linkage control mechanism refers to a control device or system in a fuel combustion system used to coordinate the automatic, orderly, and safe start-up, shutdown, and operation of the blower and fuel supply system, maintaining a reasonable air-fuel ratio during operation. During the operation of fuel combustion equipment, to ensure complete combustion, safe operation, and improved thermal efficiency, precise coordination and control of the supply of combustion air and fuel are essential. Traditional combustion systems often use mechanical or relay logic circuits to achieve simple linkage between air and fuel. When the ignition device activates, the fuel solenoid valve simultaneously opens to supply fuel for ignition, while the blower starts to supply air.

[0003] Traditional air-fuel linkage control relies on fixed-time relays and mechanical pressure switches. When using mechanical control structures, it is difficult to adjust the airflow synchronously according to the fuel supply. When the fuel supply increases, if the airflow does not increase synchronously, it will lead to insufficient air. Conversely, if the fuel supply decreases while the airflow remains unchanged, it will result in excessive air, causing a decrease in combustion efficiency and serious energy waste. Utility Model Content

[0004] The purpose of this utility model is to provide a wind-oil linkage control mechanism, which has the advantages of wind-oil linkage control and solves the problem that the existing oil valve control structure is difficult to adjust the air force synchronously according to the oil supply. When the fuel quantity increases, if the air volume does not increase synchronously, it will lead to insufficient air. Conversely, if the fuel quantity decreases and the air volume remains unchanged, it will result in excessive air, which will cause a decrease in combustion efficiency and serious energy waste.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model combines the mechanical operation of the control handle with electronic sensing technology to achieve precise synchronous adjustment of oil supply and air volume. When the user rotates the control handle, not only does the oil valve opening change directly through the mechanical connection, but the magnet on the handle also generates a magnetic field change with rotation. This change is detected in real time by the Hall sensor and converted into a voltage signal. The central controller calculates the rotation angle of the handle based on this signal and automatically adjusts the fan volume according to the preset air-oil ratio. This mechatronic design abandons the traditional independent air-oil control method and realizes the proportional linkage control of air volume and oil volume, improving the response speed and control accuracy of the combustion system, ensuring that the combustion process is always in a highly efficient and stable state, effectively improving energy utilization efficiency and reducing emissions.

[0019] 2. This utility model features a high degree of integration and intuitive, convenient operation. The gear adjustment indicators and pointers on the control panel provide clear mechanical angle feedback. The display module shows the current wind speed in real time. Combined with the control buttons, it can realize functions such as system start / stop, mode switching, and parameter setting, enhancing the human-machine interaction experience. The design of the shell and sealing ring effectively protects the internal electronic components from external oil and impurities, improving the reliability and service life of the system. The overall structure is compact and easy to install. It is suitable for various combustion equipment that requires coordinated wind and oil control, and has good practicality and promotional value.

[0028] Please see Figures 1-7 A wind-oil linkage control mechanism includes a control handle 1, which is connected to an oil valve. The oil supply is adjusted by rotating the control handle 1. A control panel 2 and a control module 3 are installed on the control handle 1. The control module 3 detects the rotation angle of the control handle 1 and adjusts the air volume according to the rotation angle.

[0029] Furthermore, the control handle 1 includes a control head 101 and a magnet 104.

[0030] Furthermore, the control module 3 includes a circuit board 301, on the top of which is a Hall sensor 305. The Hall sensor 305 is located outside the magnet 104 and adjusts the airflow according to the voltage signal.

[0031] Furthermore, a handle 102 is mounted on the surface of the control head 101, and a rotating head 103 is provided at the bottom of the control head 101. A magnet 104 is mounted on the surface of the rotating head 103 or the bottom of the handle 102, and the magnet 104 rotates with the rotating head 103 or the handle 102.

[0032] Furthermore, a control lever 105 is mounted on the bottom of the rotary head 103, and a connector 106 is mounted on the bottom of the control lever 105. The connector 106 is mounted on the valve core of the oil valve.

[0033] Furthermore, the control panel 2 includes a board 201, a first through hole 205 is provided at the center of the board 201, a second through hole 306 is provided at the center of the circuit board 301, and the rotating head 103 is located in the first through hole 205 and the second through hole 306 and is rotatably connected to them.

[0034] Furthermore, the top of the plate 201 is surrounded by gear adjustment markings 204, and the top of the control head 101 is provided with an indicator head that works in conjunction with the gear adjustment markings 204.

[0035] Furthermore, the top of the panel 201 is provided with a button hole 202 and a display hole 203.

[0036] Furthermore, a display module 302, a control button 303, and a central controller 304 are also installed on the top of the circuit board 301. The control button 303 is located inside the button hole 202, and the display module 302 is located inside the display hole 203.

[0037] Furthermore, a housing 4 is installed on the control handle 1 and the control panel 2, the control module 3 is located in the inner cavity of the housing 4, the control panel 2 is located on the top of the housing 4, and a mounting base 5 is installed on the bottom of the housing 4, which is mounted on the top of the oil valve.

[0038] Furthermore, a mounting ring 7 is installed at the bottom of the control module 3. The mounting ring 7 is located inside the control handle 1 and is movably connected to its interior.

[0039] Furthermore, a bottom cover 6 is fixedly connected to the bottom of the housing 4.

[0040] Furthermore, the display module 302, control button 303, and central controller 304 are electrically connected to the circuit board 301. The start and stop can be controlled by the control button 303, the display module 302 displays the real-time wind force, and the central controller 304 receives the voltage signal from the Hall sensor 305 and adjusts the wind force of the fan according to the change of the voltage signal.

[0041] Furthermore, when the magnet 104 rotates around the circumference inside the Hall sensor 305, the direction and intensity of the magnetic field change. The charges in the Hall sensor 305 are deflected by the Lorentz force, thereby generating a Hall voltage. The Hall voltage is processed by the signal conditioning circuit, and finally output voltage or digital signal change.

[0042] When controlling the oil supply, the user holds the handle 102 and rotates the control head 101 clockwise or counterclockwise. The control head 101 drives the rotating head 103 at the bottom to rotate together. The control rod 105 and connector 106 at the bottom of the rotating head 103 rotate accordingly, mechanically connecting the oil valve core, thereby linearly adjusting the oil valve opening and changing the oil supply.

[0043] The magnet 104, mounted on the rotating head 103 or handle 102, rotates synchronously with it. The Hall sensor 305, fixed on the circuit board 301, is located outside or at the bottom of the magnet 104 and detects changes in the magnetic field. The Hall sensor 305 outputs a continuously changing analog voltage signal based on the changes in the magnetic field. The voltage value has a linear or preset functional relationship with the rotation angle of the control handle 1. The voltage signal output by the Hall sensor 305 is transmitted to the central controller 304 on the circuit board 301. The central controller 304 performs analog-to-digital conversion and filtering on the received voltage signal to calculate the precise angular position of the current control handle 1. The central controller 304 generates a corresponding air volume control command based on the preset air-oil ratio mapping relationship. The command is sent to the fan frequency converter or damper actuator through the communication interface to adjust the fan speed or damper opening in real time, thereby achieving synchronous and proportional adjustment of the air volume and oil supply.

[0044] The preset airflow can be set to N levels, allowing users to observe the oil delivery and combustion status. Users can also change the preset airflow via control button 303 to achieve real-time linkage control between the airflow and the oil.

[0045] The existing fuel delivery is pumped by a fuel pump. With the air-fuel linkage control mechanism, the control and delivery of fuel can be saved by the fuel pump. Fuel enters the fuel valve directly by gravity. The fuel quantity is directly regulated by adjusting the valve core of the fuel valve through the air-fuel linkage control mechanism. Through integrated design, the failure rate is reduced and the fuel delivery cost is reduced.

[0046] The oil pump output can also be controlled by the air-oil linkage control mechanism. The oil pump is connected to the oil valve, and the oil output can be directly adjusted by adjusting the valve core of the oil valve through the air-oil linkage control mechanism.

[0047] The display module 302 displays the current gear position in real time. The gear adjustment indicator 204 works in conjunction with the indicator head on the handle 102 to provide intuitive mechanical angle indication. Users can perform operations such as system start / stop, mode switching, and parameter setting through the control button 303.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
