Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1

As shown in fig. 1 and fig. 2, a timer switch that gas stove was used, including switch body 1, be equipped with the cavity in the switch body 1, install battery 2 in the cavity, in this embodiment, battery 2 adopts high temperature resistance lithium cell, be equipped with OLED display screen 3 in lithium cell 2's top, below at lithium cell 2 is equipped with controller 4, controller 4 is connected with lithium cell 2 electricity, lithium cell 2 is controller 4 and OLED display screen 3 power supply, in addition, be equipped with USB interface 11 on switch body 1, the USB interface is used for charging for the lithium cell, be equipped with transparent upper cover 5 in OLED display screen 3's top, people can see the display screen through the upper cover like this, can play certain guard action to display screen and inside circuit structure when not influencing the use of display screen.

As shown in fig. 3, the controller includes a control unit, in this embodiment, the control unit employs a single chip microcomputer whose model is STM32F205RE, and since the working principle thereof belongs to the conventional technical means in the art, the details are not described in this embodiment.

This singlechip is connected with the time-recorder, and in this embodiment, the time-recorder adopts the 555 time-recorder, and the time-recorder is used for timing the heating time.

In addition, the single chip microcomputer is connected with an angular velocity sensor, the angular velocity sensor is used for detecting the rotating angle of the switch, so that whether the gas stove is opened or not is determined, and the specific opening degree is determined.

When the switch is used for the first time, the angular velocity sensor needs to be calibrated, and specifically, two calibration methods exist, as shown in fig. 4, the first method is to press the switch, rotate the switch counterclockwise by 180 degrees, rotate the switch clockwise by 180 degrees to reset the switch to 0 degree, and repeat the operation for 3 times to complete the calibration.

As shown in fig. 5, the second method is to press the switch, stay for 3 seconds, then release, and repeat this three times.

Further, this singlechip still is connected with gravity sensor, in this embodiment, gravity sensor adopts the four directions gravity sensor that the model that Shenzhen china's Hua Jingbaofeng electronics limited company produced is BF-16, because the gas-cooker switch need push down the switch when opening, so through increasing gravity sensor in the switch, it just can detect through gravity sensor to push down as the switch like this, thereby signal is given the singlechip, the singlechip signals is given the time-recorder, the time-recorder begins to count, and show through OLED display screen with concrete digit, convenience of customers knows concrete heating time, thereby the accuracy is controlled heating time, improve the taste of culinary art food.

In addition, the single chip microcomputer is also connected with a buzzer, the buzzer is a TMB12A05 buzzer, and the buzzer is used for reminding a user when the continuous heating time reaches or exceeds the set time of the user, so that the use risk of the gas stove is reduced.
