Touch pen, control method thereof, touch device and readable storage medium

A touch device, comprising:

• a first device and a touch pen;
• wherein, the touch pen comprises a pen body, a controller, a detecting part, and an accommodation part, and the controller, the detecting part, and the accommodation part are arranged on the pen body;
• wherein the detecting part is provided with a current detecting circuit, there is a conductive fluid in the accommodation part, and the accommodation part is connected to the detecting part;
• wherein at least a part of the current detecting circuit is located inside the detecting part, and the current detecting circuit is configured to contact the conductive fluid and form a circuit with the conductive fluid when the pen body is in a tilt posture, and output a corresponding reference value according to magnitude of a current in the circuit;
• wherein the controller is electrically connected to the current detecting circuit, and is configured to output a control signal according to the reference value;
• and
• wherein the first device is configured to receive the control signal outputted by the controller of the touch pen,
• wherein when the touch pen is in a vertical state, the current detecting circuit is not in contact with the conductive fluid.
