Abstract

The creation is made using ultrasonic sensors, infrared sensors, voice module, Bluetooth module, hot and cold wind device and fan motor, when someone sit down and the induction hot and cold wind chair, the induction hot and cold wind chairs that automatically start cold or hot air, users can take advantage of the sound or Bluetooth to control the switching of wind strength, with hot and cold wind, allowing users to be able to sit comfortable this induction hot and cold winds chair. If the user to chair tilted at an angle, the induction hot and cold winds chair will send out a signal to the alarm device audible alarm to remind the user to fall down, and when the user leaves the chair, the hot and cold air will automatically stop the action, in order to achieve a convenient use and energy-saving effect.

Description

Induction hot and cold wind chair

This creation is a chair that uses electronic devices and sensors. Its application technology includes single-chip control technology, infrared sensing technology, ultrasonic sensing technology, tilting technology, voice control technology, Bluetooth technology, and alarm technology.

Generally, the chair can only be used for sitting. When the ambient temperature changes, the user needs to have an electric fan or a heater to use it. The old fan and the heater used in the past are easy to consume electricity and heat, and are not environmentally friendly. The fan blade is not easy to be cleaned by the user. The chair itself does not have the function of fan or hot air, sensor, voice control and alarm. Before the design of the cool wind cushion, the wind is not strong and there is no hot air design. The hot and cold wind chair can control the intensity of the wind and the switching of hot and cold air.

This creation is based on the convenience and safety of the user. The user can feel the intensity of the wind sitting on the inductive hot and cold air chair. At this time, the sound control module and the Bluetooth module can be used to control the hot and cold wind and the wind. Size, when the user wants to blow cold air or hot air, they can directly perform the action through the voice control module or the Bluetooth module; while the tilting device detects that the inductive hot and cold air chair has fallen backwards, at this time The alarm device will sound an alarm to protect the user's safety.

The application technology of the inductive hot and cold air chair of the creative function includes a single chip controller (10), an ultrasonic sensor (11), an infrared sensor (12), a sound control module (17), and a Bluetooth module ( 16), the fan motor (15), the hot air device (13), the cold air device (14), and the alarm device (20) are integrated, and when the human body sits on the inductive hot and cold air chair, the ultrasonic sensor (11) and When the infrared sensor (12) detects the user at the same time, it sends a signal to the single-chip controller (10), and the single-chip controller (10) sends the signal to the fan motor (15) to start the hot and cold wind. So that the cold air or hot air will guide the cold air or hot air to the user's hands and shoulders through the duct. At this time, the user can use the voice control module (17) and the Bluetooth module in the inductive hot and cold air chair. ) to control the switching of the hot air device (13) and the cold air device (14).

In addition, if the user accidentally tilts the inductive hot and cold air chair beyond a certain angle, the tilting device (19) sends a signal to the single chip controller (10), and the single chip controller (10) sends a signal. The alarm device (20) is sounded to alert the user that the user's life is safe from harm.
