Smart voice-control safety vertical electric fan with infrared positioning function

Abstract

The invention discloses a smart voice-control safety vertical electric fan with an infrared positioning function. A steering engine is mounted in a fixing frame, a steering engine arm on a steering engine rotary shaft is connected with a support, an electric fan is mounted on the upper portion of the support, pyroelectric infrared sensors are mounted in two holes of the middle of the support perpendicularly, Fresnel lenses are respectively mounted on the outer sides of the two pyroelectric infrared sensors, and a temperature sensor, a voice control sensor and a gravity acceleration sensor are mounted in the support and connected with a single-chip microcomputer through respective circuits. By induction functions of the sensors and smart processing of the single-chip microcomputer, various environmental information of the external can be fed back by the circuits in real time, working states of the electric fan can be changed along with change of the external environment according to different angle and rotation speed of the steering engine and the fan, and users feel more comfortable when using the electric fan. When the electric fan topples, the power source can be cut off in time, so that the users and the electric fan can be protected. When the users leave a work range of the electric fan, the electric fan can be turned off automatically, so that energy saving and environmental protection effect can be realized.

Description

technical field [0001] The invention relates to a safety electric fan, in particular to an infrared ray positioning intelligent sound control safety vertical electric fan. Background technique [0002] At present, most of the existing vertical fans are open-loop control without feedback, and can only rotate mechanically at a certain frequency and angle during operation. Most of the fans on the market today adopt mechanical swinging air supply structure and timing shutdown design, which is not enough control It is flexible, and cannot sense the user's position and ambient temperature, and cannot realize smart switches. Among the smart electric fans that have come out so far, such as the utility model ZL200920020891 "a kind of intelligent electric fan" has an infrared positioning device, which can track the human body moving indoors in real time, but it does not have a two-person blower mode, nor can it adjust the fan according to indoor temperature changes. The speed is adju...

[0002] At present, most of the existing vertical fans are open-loop control without feedback, and can only rotate mechanically at a certain frequency and angle during operation. Most of the fans on the market today adopt mechanical swinging air supply structure and timing shutdown design, which is not enough control Flexible, and unable to sense the user's position and ambient temperature, and cannot realize smart switches

Among the smart electric fans that have come out so far, such as the utility model ZL200920020891 "a kind of intelligent electric fan" has an infrared positioning device, which can track the human body moving indoors in real time, but it does not have a two-person blower mode, nor can it adjust the fan according to indoor temperature changes. The speed is adjusted; another example is the utility model ZL200520057178 "temperature-controlled intelligent electric fan" that can adjust the fan speed by sensing changes in the external temperature, but it does not have a human body tracking and positioning system and a voice control mode, and there is still a certain waste in resource utilization.
