Description

Smart fan

The present invention relates to an electric fan structure with wireless communication and static electricity detection, in particular to a radio remote control electric fan, which is convenient for changing the rotational speed and wind direction of the electric fan, and a method for detecting human touch by using static electricity, thereby safely closing or opening. Electric fan.

For a long time, electric fans and air-conditioners are indispensable tools for people's daily life, and electric fans are a tool to improve the cooling effect of air-conditioners.

The design of the starting, closing, wind speed control and wind direction control of the conventional electric fan requires the user to operate the key switch to achieve the goal. These push button switches not only complicate the structure of the electric fan, but also increase the manufacturing cost and weight, which hinders the fashion design. Such a hard button design also makes the patient or the inconvenienced person inconvenienced, inconvenient to use (must move and bend down), and also makes the fingers of the young child have an unsafe feeling of turning the rotating blade.

[M404898] The structure of the electric fan mentioned is to increase the infrared detection to improve the wasteful electric behavior of the user who forgets to turn off the electric fan when he leaves. However, due to the use of such an electric fan, it is necessary to face the user for a certain period of time in order to continue to operate and send out the airflow, so that it is otherwise unwilling to blow the electric wind. The inconvenience of the fan user.

In view of the above requirements, the main purpose of this creation is to provide a smart and stylish electric fan that is easy to produce and assemble, saves electricity, is light, and is easy to operate and safe.

In order to achieve the above object, an electric fan structure having wireless communication and static electricity detection includes an airflow generating body having at least one blade, a motor and a motor driving circuit, and the motor driving circuit controls the one. The motor drives the blade to generate airflow; a microprocessor is used to program the normal operation of each unit of the electric fan device; and a communication module can accept external wireless control commands (for example, an APP program on a smart phone or a tablet) The Bluetooth remote control, the microprocessor drive circuit controls the motor to drive the blade to generate airflow of different directions and strengths; and an electrostatic sensing module for detecting the human body Touching static electricity and outputting a signal; the microprocessor can enable the static sensing module to detect static electricity of the human body in the airflow generation to turn off the airflow for safety purposes, and detect the special human body when the airflow stops Static input method (for example: finger touch, leave each three times) to restart the generation of airflow; a power supply unit is used to supply the power required by the device And an electric fan support seat for supporting the electric fan device. In addition, the microprocessor can allow the communication module to check whether the communication link still exists within a certain period of time (for example, 5 or 10 minutes). If it does not exist (that is, if the user forgets to turn off the electric fan when leaving), turn off the electric fan to save power.

The differences between the creation and the prior art are as follows: (1) The communication module can accept external wireless control commands (for example: wisdom hand) The application program on the computer or tablet is remotely controlled by Bluetooth or other communication interface to generate airflow in different directions and intensities. The airflow intensity can be changed in segments or without segments; (2) the communication module is in a certain period of time ( For example: 5 or 10 minutes), do you want to check if the communication link still exists? If it does not exist (that is, if the user forgets to turn off the electric fan when leaving), the electric fan is turned off to save power; (3) the soft button control design of the communication module also makes the patient or the inconvenienced person, It is convenient to use the electric fan without walking and bending down; (4) the static sensing module can detect the static electricity of the human body during the airflow generation to close the airflow for safety purposes; (5) the electrostatic sensing module In the group, when the airflow stops, the special human body static input mode is detected (for example, the finger touches and leaves each time three times) to restart the airflow generation (ie, the electric fan is turned on); (6) the creation does not use the conventional key switch. As a control of the airflow strength and direction, it simplifies the structure of the electric fan, reduces the manufacturing cost and weight, and is more conducive to fashion design.
