Fan with adjustable speed for industry and commerce

Abstract

The invention discloses a fan with an adjustable speed for industry and commerce. The fan with the adjustable speed comprises a fan main body, a shaking motor, a blade rotation motor and a circuit board, wherein the fan main body at least comprises a housing and blades, the circuit board comprises a circuit main board, and a display and key control board, the shaking motor, the blade rotation motor, the circuit main board, and the display and key control board are arranged in the housing, and the blades are rotationally arranged outside the housing and mutually drive with the blade rotation motor; and the circuit main board comprises a main control chip circuit, a shaking control circuit, a blade rotational speed control circuit, an alternating-voltage zero-crossing detection circuit, a direct-current stabilization circuit, an isolation transformer circuit, a temperature sensor circuit, a buzzer circuit and an emulator circuit. The fan with the adjustable speed further comprises a display and key control module, and a remote control module, wherein the display and key control module is connected with the display and key control board in a matching manner, and connected with the main control chip circuit in an electronic control manner through a display and key control connection port, and the remote control module is connected with the main control chip circuit in an electronic control manner through a remote control connection port.

Description

technical field [0001] The invention relates to an adjustable speed fan for industry and commerce. Background technique [0002] Existing industrial and commercial fan control methods are mainly realized by manual and mechanical methods. When using it, you need to approach and turn on the fan to let the fan operate. It is inconvenient for users to use related operation modes. In order to solve the above problems, the technicians developed a remote control for remote control of the fan. Although it can solve the problem that the user must approach the fan to control it, the remote control only has "high-end", "middle-end" and "low-end". Or "first gear", "second gear", "third gear" and other gear speed selections. These gear speeds have been basically fixed at the factory, resulting in uncontrollable wind speed. With the improvement of people's living standards, people's requirements for fans are also increasing. As the wind speed increases day by day, the fixed wind speed m...

In order to solve the above problems, the technicians developed a remote control for remote control of the fan. Although it can solve the problem that the user must approach the fan to control it, the remote control only has "high-end", "middle-end" and "low-end". Or "first gear", "second gear", "third gear" and other gear speed selections. These gear speeds have been basically fixed at the factory, resulting in uncontrollable wind speed. With the improvement of people's living standards, people's requirements for fans are also increasing. As the wind speed increases day by day, the fixed wind speed may easily cause the wind speed required by the user to be too large or too small, and these multi-speed switches cannot intuitively reflect the current use status of the fan, which is not conducive to the user's correct judgment and selection of the appropriate speed, resulting in insufficient wind speed of the fan or excessive, and there is no intuitive display of the speed on the fan, the user experience is not high
