Background technique

With the vigorous development of high-tech industries and the improvement of GDP, people’s pursuit of fashion is becoming more and more intense. Since the barber shop perm is expensive and the damage to the hair is increasing, choosing a smart electric curling iron is nothing more than a best choice.

However, the traditional curling iron has no program setting function and no angle detection, so the curling arc cannot be fixed, and the hairstyle is often asymmetrical or messy due to shaking and dislocation, and the curling iron is always heated during the operation. In this state, the user is often scalded, and the long-term operation causes excessive burden on the hands and a sore feeling. Therefore, the traditional curling iron is quite inconvenient to use and has many defects.

Utility model content

The purpose of the utility model is to solve the problem that the electric hair curling iron in the prior art cannot be controlled by electric signals, and to provide an electric hair curler control module that reduces the complexity of self-styling and has safety protection measures.

The technical scheme of the present utility model is:

An electric hair curler controlled by a MEMS gyroscope, comprising a hair curler handle and a hair curler with a heating core, the hair curler handle being provided with a switch, a program panel, a heating module electrically connected with the heating core of the hair curler, and a The hair curling iron is driven and connected to a micro motor, the program panel is electrically connected with the heating module and the micro motor; the electric hair curler further includes a control module, the control module includes a controller and a rotation angle for detecting the rotation angle of the hair curling iron The controller provides a gyroscope with electrical signals; the controller is respectively electrically connected with the micromotor, the heating module and the gyroscope.

The gyroscope is a MEMS gyroscope sensor.

The electrical signal represents the rotational angular velocity or angle of the curling iron.

The utility model has the following beneficial effects:

(1) The curling program can be freely selected through the program panel to meet the different needs of different groups of people and achieve different curling degrees, so that the hair can be blown and straightened.

(2) It has an angle detection feedback system, but if it detects that the angle of curling is incorrect, feedback control can be performed to achieve the desired effect;

(3) With safety protection measures, when it is detected that the curling rod reaches a certain angle, the curling rod will be heated and set, will not be scalded, and prevent the micro motor from further rotating and wrapping the hair.

detailed description

In order to make the technical means, technical features, utility model purpose and technical effect realized by the present utility model easy to understand, the present utility model will be further described below with reference to the specific figures.

As shown in Figure 1: an electric hair curler controlled by a MEMS gyroscope, including a hair curler 1, the hair curler is provided with a switch 2, a hair curler 3, a heating module 4, a micro motor 5, a program panel 6 and a control module 7. The micromotor 5 drives and connects the curling iron 3, the heating core in the curling iron 3 is electrically connected to the heating module 4, and the program panel 6 is arranged at the handle 11 of the curling iron 1 and is connected to the heating module 4. , the micro motor 5 , the program panel 6 and the control module 7 are electrically connected.

The control module 7 includes: a MEMS gyroscope sensor 71, the MEMS gyroscope sensor 71 detects the rotation angle of the hair curling rod 3, thereby providing an electrical signal, the electrical signal represents the rotation angular velocity/angle of the hair curling rod 3, as shown in FIG. 2 : the MEMS gyro chip 73 of the MEMS gyro sensor 71 , the arrow in the figure is the rolling direction of the curling iron 3 .

A controller 72 configured to receive electrical signals from the MEMS gyroscope sensor 71 and operate to determine and respond to whether the angular velocity/angle of curling of the curling iron 3 exceeds a threshold value while the curling iron 3 begins to heat and set, thereby preventing The micro motor 5 continues to drive the rotation of the curling iron 3 .
