DOOR LOCK AND THE ELECTRICAL DEVICE CONTAINING IT

Claims

1. A door lock, characterized in that it contains: a main slider capable of being driven by a door hook into a reciprocating motion in the first direction; a control circuit and a control switch, wherein the control switch enables or disables the control circuit based on the position of the main slider; a reading circuit and a reading switch, wherein the reading switch enables or disables the reading circuit based on the position of the main slider; and a distribution box, wherein the control circuit and the control switch are located inside the distribution box, and the sensing circuit and the sensing switch are located outside the distribution box.

2. A door lock according to paragraph 1, characterized in that: The control circuit power supply is a high voltage power supply, and the sensing circuit power supply is a low voltage power supply.

3. A door lock according to paragraph 1, characterized in that: the main slide has a locked position and an unlocked position; and The door lock further comprises a reading switch actuating element configured to turn on the reading switch in response to the main slider being in the unlocked position, thereby connecting the reading circuit; and to turn off the reading switch in response to the main slider being in the locked position, thereby disconnecting the reading circuit.

4. A door lock according to paragraph 3, characterized in that: the main slider performs a reciprocating movement in the first direction between a locked position and an unlocked position, and the sensing switch actuating element comprises a switch slider; wherein the main slider is capable of causing the switch slider to move in the first direction.

5. A door lock according to paragraph 4, characterized in that: the sensing switch comprises a first contact terminal and a second contact terminal, and the sensing switch actuating element comprises an elastic member made of a conductive material; and wherein the elastic part is connected to the switch slider for moving in the first direction with the switch slider; wherein the sensing switch actuating element is designed in such a way that as the main slider causes the switch slider to move, the elastic member is capable of coming into contact with the first contact terminal and the second contact terminal to connect the first contact terminal and the second contact terminal; or the elastic member is capable of moving a distance from at least one of the first contact terminal and the second contact terminal to disconnect the first contact terminal and the second contact terminal.

6. A door lock according to paragraph 5, characterized in that: the elastic member comprises a pair of legs formed with an inclined offset from each other in a first direction; wherein the distance between the pair of legs in the second direction is set in such a way that the maximum distance is greater than the distance between the first contact terminal and the second contact terminal, and the minimum distance is less than the distance between the first contact terminal and the second contact terminal.

7. A door lock according to paragraph 6, characterized in that: each leg of the pair of legs further comprises an arcuate section, wherein the arcuate section of each leg of the pair of legs is curved into an arc in opposite directions, wherein the elastic part is designed with the possibility of coming into contact with the first contact terminal and the second contact terminal on the arcuate sections.

8. A door lock according to paragraph 4, characterized in that: the reading switch comprises a microswitch, and the reading switch actuating element comprises an elastic button elastically deformable in a first direction; wherein the actuating element of the reading switch is designed in such a way that the elastic button is capable of being compressed and deformed by the slider of the switch, turning on the microswitch, and is capable of being expanded and restored, turning off the microswitch, as the main slider causes the slider of the switch to move.

9. A door lock according to paragraph 1, characterized in that it contains: a cam configured to receive the door hook and cause the main slider to move in a first direction; and a locking pin capable of moving in a third direction to lock or unlock the main slider and cam, wherein one end of the locking pin extends into the distribution box to turn on the control switch when the main slider and cam are locked, or to turn off the control switch when the main slider and cam are unlocked.

10. An electrical appliance, characterized in that it contains: a door lock according to any of paragraphs 1-9.
