Description

Sound-activated electric fan

technical field

The utility model relates to an electric fan, in particular to a sound-controlled electric fan.

Background technique

Existing electric fans are mainly composed of fan blades, guards, motors, speed control switches, oscillating blade switches, timers and machine bases. The electric fans are controlled by manual operation.

At present, relatively new electric fan products include "remote control type" and "gust type". The advantage of "remote control electric fan" is that the user can control the operation by a transmitter (such as infrared or radio) within a certain distance, but it still cannot do without manual operation. The advantage of "gust-type electric fan" is that through program control, the fan moves according to a certain pattern, and the air volume sent out is cycled from weak to strong to weak, simulating natural wind, but manual operation is still inseparable.

The patent number 97210646.4 designed by Wang Bensheng is "Temperature Control Automatic Electric Fan". The temperature control automatic electric fan is characterized by a switch, a transmission, a temperature sensor and an electric fan connected in series. The electric fan can be automatically started or stopped according to the temperature set as required. The electric fan realizes the automatic control of the indoor temperature. The temperature-controlled automatic electric fan does not need to be manually operated. It is automatically controlled according to the change of the room temperature. The control setting temperature is fixed and single, but the physiological conditions of different people are different. needs, simply according to the ambient temperature can not meet people's needs.

Utility model content

The utility model provides a sound-activated electric fan in order to solve the problem that the above-mentioned electric fan is controlled by manual operation.

The sound-activated electric fan includes a fan body, and the fan body mainly includes five parts: a head, an oscillating head, a bracket, a machine base and a power cord. The power supply is connected to the voice control device through a switch, and the other end of the voice control device is connected to a motor and a light bulb in turn. The sound control device is composed of a sound sensor and a control circuit, and the sound sensor is connected with the control circuit. The power supply is connected with the rectification and voltage stabilization module, and the rectification and voltage stabilization module is connected with the alarm clock. The bottom of the fan body is provided with a pulley, and the pulley has a locking device.

The utility model solves the problem that the electric fan is controlled by manual operation, controls the electric fan by changing the sound level, and automatically starts, changes the wind speed or stops the electric fan according to the sound level set as required. Manual action is required. In addition, the electric fan can be adjusted by voice at any time according to actual needs, which is more flexible than the temperature-controlled automatic electric fan and meets actual needs.

The utility model is also designed with an electric bulb and an alarm clock, and a pulley is arranged under the support, and the pulley has a locking function. These designs increase the convenience and practicality of the electric fan. The light bulb has the function of lighting, and also has the function of a night light at night; the alarm clock is convenient for knowing the time; the pulley is convenient for the movement of the voice-activated electric fan, and the locking device of the pulley increases the safety and stability of the voice-activated electric fan.

The utility model is applicable to family rooms and offices for environment temperature regulation and heatstroke prevention and cooling of the human body. It does not need manual operation, and realizes automatic control of the electric fan by sound to meet actual needs.
