Problems solved by technology

The core idea of ​​the above two schemes is to avoid accidental start-up of the operator when the operator is unconscious or not intending to start up, which reduces the risk of accidental injury when the cutting tool is turned on to a certain extent, but for some inexperienced, especially For children with a certain degree of curiosity, starting the machine unconsciously still often occurs. For example, in the scheme of the above-mentioned main and auxiliary switches, as long as the operator turns

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0037] according to figure 1 and figure 2 , taking an electric chain saw as an example, the illustrated electric chain saw includes a main casing 1, a cutting assembly 2, a main handle, an auxiliary handle, a hand brake plate 5, and a trigger 4 is provided on the main handle. The trigger 4 controls the closing or opening of the main switch S1, and the main control unit judges whether there is a switch signal by detecting whether the main switch S1 is closed. The hand guard brake plate 5 can be switched between the braking position and the non-braking position. In the braking position, the brake switch S2 is closed. In the non-braking position, the switch S2 is disconnected. Signal.

Abstract

The invention belongs to the field of electric cutting tools, particularly relates to a control system and a control method for an electric cutting tool, and is particularly suitable for controlling an electric chain saw. The control system comprises a main housing (1), a main switch S1, a brake switch S2 and a cutting component (2) positioned at the front end of the main housing (1), wherein a master control unit and a motor (3) are arranged in the main housing (1); the motor (3) is controlled by the master control unit to drive the cutting component (2). The control system is characterized in that an LED alarming lamp (6) and an alarming buzzer (7) are further arranged on the main housing (1), wherein the master control unit comprises a touch signal detection unit, a braking signal detection unit and a switching signal detection unit, and correspondingly controls the LED alarming lamp (6), the alarming buzzer (7) and the motor (3) under conditions a) to d) according to detected signal conditions. The control system and the control method are high in safety performance, and the risk of accidental injury caused by a cutting blade under an unconscious starting condition is further reduced.

Description

technical field [0001] The invention belongs to the field of electric cutting tools, and in particular relates to a control system and a control method of electric cutting tools, and is especially suitable for the control of electric chain saws. Background technique [0002] Electric cutting tools, such as electric chain saws, electric hedge trimmers, etc., usually have exposed cutting blades, and special attention needs to be paid to safety issues when starting the machine. In the existing electric cutting tools, the main and auxiliary switches are respectively set on the main handle and the auxiliary handle of the machine, and the machine can only be turned on by turning on the switches with both hands at the same time; , only when the lock is unlocked can the switch be turned on to start the machine. The core idea of ​​the above two schemes is to avoid accidental start-up of the operator when the operator is unconscious or not intending to start up, which reduces the ris...
