Time switch of controllable time adjustment

1. A time switch of controllable time adjustment, comprising:

a switch housing,

a control circuit board,

an input terminal,

an output terminal,

a connecting piece,

a first spring,

a warped plate, and

an electromagnet; wherein

the control circuit board is arranged inside the switch housing and electrically connected to the electromagnet and the output terminal; the control circuit board is configured to control the electromagnet to be powered on according to a turn-off time preset by the control circuit board;

the electromagnet is configured to push the warped plate;

the warped plate configured to bend the first spring is connected to the switch housing by means of a rotating shaft;

the first spring is provided between the warped plate and the connecting piece to enable the warped plate to sway around the rotating shaft and drive the connecting piece to sway;

the connecting piece is configured to connect the input terminal and the output terminal;

the input terminal and the output terminal are arranged on a bottom surface of the switch housing; the swaying of the connecting piece causes the input terminal and the output terminal to complete closing and opening, such that the time switch is turned on and off;

wherein the time switch further comprises a timing rotary switch electrically connected with the control circuit board;

wherein the timing rotary switch comprises a first circuit board, a rotary switch, a rotary knob and a case; a circular hole is arranged on a top surface of the case; the rotary knob is exposed out of the case through the circular hole for rotation; the rotary switch is set on the first circuit board; the rotary knob is sleeved on a rotary shaft of the rotary switch; and the first circuit board is electrically connected with the control circuit board by a plug wire;

wherein the time switch further comprises a waterproof rubber ring arranged inside the switch housing; and the waterproof rubber ring is provided between the warped plate, the connecting piece and the control circuit board.

2. The time switch of claim 1 , wherein the control circuit board comprises a microcontroller configured to control the electromagnet to be powered on according to the turn-off time.

3. The time switch of claim 1 , wherein the time switch further comprises a bottom cover connected to the switch housing of the time switch via a buckle.

4. The time switch of claim 1 , wherein an opening is provided on a top surface of the warped plate; a lamp cover is clamped in inner of the opening.

5. The time switch of claim 1 , wherein the electromagnet comprises a copper coil, a coil framework, a second spring, a terminal and an iron core; the second spring is sleeved on the iron core, the iron core is arranged inside the coil framework, the copper coil is wound and sleeved on the coil framework; the terminal is provided on the coil framework; and the copper coil is electrically connected to the terminal.
