Electronic device used for fan and intelligent fan with electronic device

Abstract

The invention relates to the field of electric fans, in particular to an electronic device used for a fan and the intelligent fan. The problems that when a common fan uses an infrared remote control, the remote control angle and the remote control distance are limited, and a timer is inaccurate and low in precision are solved. The fan has the problems that no stepless speed regulation exists / a user feels uncomfortable when the natural air is used / the wind speed is too large for infants / the sleeping needs cannot be met / the different use occasions cannot be met / remote operation cannot be achieved through the internet. The electronic device is mounted between an original fan circuit control system and a fan core component, by detecting whether voltage exists in the original fan circuit control system or not and through detection of the change condition of the voltage, the manual operation of the user for the fan is identified, meanwhile, the WIFI / Bluetooth / Zigbee / 2G / 3G / 4G wireless manner is used for replacing the traditional infrared manner, and the user can carry out remote control through an intelligent terminal; through the manner, fan new mold making / circuit board design / development and production investment for replacement of a direct-current motor can be avoided, and the production cost of the intelligent fan can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric fans, in particular to an electronic device for turning an ordinary electric fan into a smart fan and a smart fan with the remote control function of a smart terminal. Background technique [0002] There are a wide variety of electric fans, ranging in price from low-end tens of yuan to high-end hundreds of yuan or thousands of yuan. There are also desk fans, lucky fans, floor fans, wall-mounted fans, etc. in terms of appearance. Ordinary electric fans, humidifying fans with water pumps and mist generators, air-conditioning fans with humidification and heating functions, etc. But they generally have several problems. [0003] The problem of inconvenient operation: For low-end fans, there is generally no remote control, and the user must manually operate on the fan; for fans with a remote control, the remote control is usually an infrared remote control, and the characteristics of infrared signals...

AI Technical Summary

Problems solved by technology

[0003] The problem of inconvenient operation: For low-end fans, there is generally no remote control, and the user must manually operate on the fan; for fans with a remote control, the remote control is usually an infrared remote control, and the characteristics of infrared signals The control angle is limited, the distance is limited and the remote control cannot be controlled when it is blocked

There are still big deficiencies in this implementation method: 1. It is not suitable for fan products without IC chips, which are often lower-end and lower in price; 2. The original IC chip of the fan needs to be upgraded and replaced , Modify the original circuit board, re-mold the fan casing to adapt to the new circuit board

[0008] It is necessary to use a DC motor to achieve more wind speed adjustments, and the DC motor costs more, and the supporting control circuit is more complicated

Due to such shortcomings, new results have emerged: 1. Fan products without IC chips still cannot solve several problems existing in ordinary fans; 2. The transformation and research and development of fan products with IC chips, and DC motors The use of smart fans requires a lot of money and a lot of time, and the requirements for technicians are also higher, which also makes the cost of such smart fans much higher than that of ordinary fans.

At the same time, most small and medium fan manufacturers do not have such technical strength and cannot afford such research and development costs.

Therefore, the price of these very small number of smart fans is much higher than that of ordinary fans, and their market acceptance is not high, and users cannot enjoy the convenience brought by smart technology.
