Description

Electronic control board for fan Technical Field The utility model relates to the field of electronic control boards, in particular to an electronic control board for a fan. Background The fan electronic control board is a core component for adjusting the running state of the fan, and is generally composed of a substrate, electronic components (such as a microcontroller, a capacitor, a resistor and a relay) welded on the substrate and wires, and controls such as motor speed regulation, mode switching (natural wind/sleep wind), timing function, overload protection and the like are realized through circuit logic. Its stability directly affects fan performance and life. The existing electronic control board has the defects that the existing electronic control board is usually installed by adopting screws, the screw installation needs to use special tools such as screwdrivers, the operation is difficult in a narrow fan inner space (especially a ceiling fan or an embedded fan), peripheral components are easy to damage due to tool slippage, the screw holes of the base board and the hole positions of a fan bracket are required to be aligned accurately during installation, the warping of the base board or the inclined locking of the screws are easy to be caused due to misalignment, welding spots are cracked after long-term use, the electronic control board is inconvenient to install and detach, the screws are required to be detached one by one during maintenance or upgrading of the control board, time and effort are consumed, the screws are easy to lose (especially micro screws), and the downtime is increased, so that the electronic control board is inconvenient to install and detach by adopting the screws. Disclosure of utility model In order to overcome the defects of the prior art, the utility model provides the electronic control board for the fan, which can effectively solve the technical problem that the electronic control board is inconvenient to install and detach due to the fact that the existing electronic control board is installed by adopting screws. The technical scheme includes that the electronic control board for the fan comprises a substrate, a plurality of electronic components welded on the substrate and a plurality of wires, wherein the adjacent electronic components are electrically connected through the wires, a plurality of fixing rods are fixedly arranged at the bottom of the substrate, the adjacent fixing rods are symmetrically arranged, one ends of the fixing rods extend outwards to form a circular ring part, the diameter of one ends of the fixing rods, far away from the circular ring part, is gradually reduced, a plurality of connecting blocks are arranged at one ends of the fixing rods, close to the circular ring part, and are symmetrically arranged between the adjacent connecting blocks, a plurality of clamping strips are arranged at one ends of the fixing rods, close to the circular ring part, extend along the axial direction of the fixing rods, and are symmetrically arranged between the adjacent clamping strips. Further, the length of the clamping strip is smaller than that of the fixing rod, and the clamping strip is rectangular. Further, one end of the substrate is provided with a limit groove, and the limit groove extends along the height direction of the substrate. Further, the fixing rod is provided with three. Further, the fixing rods are all positioned on the same horizontal plane. Compared with the prior art, the electronic control board for the fan has the beneficial effects that the electronic control board is quickly assembled and disassembled by arranging the fixing rod and the connecting blocks and the clamping strips on the fixing rod, and compared with the traditional assembly by adopting screws and the like, the electronic control board is simple in structure, convenient to quickly assemble and convenient to disassemble, and other tools are not required to be used for assembly and disassembly.
