Problems solved by technology

[0002] Existing electric fans have fewer gears, and the wind speed remains unchanged after sleeping at night in summer. When the temperature is not very high and a little hot, the wind of the fan is larger and there is no breeze function, especially when the elderly and children sleep for a long time. easy to catch a cold

Embodiment Construction

[0010] The following combined with the accompanying drawings figure 2 Principle and feature of the present invention are described:

[0011] AC AC input terminal, when AC L and AC N are connected to the AC power supply, when the timer is turned on (normally closed), select the fan gear (1, 2, 3 gears) through the gear switch, and start the fan by starting the capacitor At this time, the fan works in the strong wind gear (3rd gear strong wind) state; when the timer is turned off (normally open), the AC power passes through the CBB step-down current limiting capacitor C1 and the gear switch to make the fan work in the breeze (3rd gear breeze) state , when working in the breeze state, it uses the CBB capacitor to step down and limit the current. Compared with the working mode of the inductor to step down and limit the current, the temperature is lower and the noise is smaller, and the exhausted wind is softer, so the life is longer. R1 is the discharge resistance of the CBB capa...

Abstract

The invention relates to an electric fan which comprises a fan motor, a starting capacitor, a gear switch, a timer, a CBB capacitor and a discharging capacitor. The electric fan is characterized in that the timer is provided with a speed governing circuit in parallel, and the speed governing circuit can change the power of the electric fan to enable discharged air to be soft and reduce the air discharging noise. The electric fan has the beneficial effects that work is stable, the structure is simple, cost is low, use is convenient, the service life is long, the electric fan is particularly suitable for use during sleeping at night in summer, after a user falls asleep, strong air is automatically changed into weak air, the user is not prone to catching a cold, a breeze gear can be used whenthe temperature is not too high and the user feels a little hot, a motor is small in generated heat and low in noise when the electric fan works in the breeze state, the discharged air is softer, andthe electric fan is particularly suitable for family and office spaces.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an electric fan. Background technique [0002] Existing electric fans have fewer gears, and the wind speed remains unchanged after sleeping at night in summer. When the temperature is not very high and a little hot, the wind of the fan is larger and there is no breeze function, especially when the elderly and children sleep for a long time. It is easy to catch a cold on the body. Contents of the invention [0003] The present invention aims at the above deficiencies, and provides a fan gear with several breeze gears added on the basis of the original fan gear, which can control the strong wind and breeze of the fan through the closing and disconnection of the timer, and automatically turn from strong wind to breeze after the timer is up. An electric fan. [0004] In order to solve the problems of the technologies described above, the solution of the present invention is a...
