[0027] Please refer to Figures 1-5 , a household electrical appliance control switch based on the Internet of Things, comprising an outer housing 1, a main body 2, a wire contact mechanism, a rotary connection mechanism and an automatic disconnection mechanism. It is characterized in that the wire contact mechanism includes a fixed block 3, a fixed contact rod 4, a movable block 5, a movable contact rod 6, a first spring 7 and a limiting rod 8. The fixed block 3 is fixedly installed on the main body 2, the fixed contact rod 4 is fixedly installed inside the fixed block 3, the limiting rod 8 is fixedly installed on the main body 2, the movable block 5 is installed on the limiting rod 8 and is slidably connected to the limiting rod 8, the movable contact rod 6 is fixedly installed at the bottom of the movable block 5, the movable contact rod 6 is detachably connected to the fixed block, both ends of the first spring 7 are fixedly connected to the top end of the fixed block 3 and the bottom end of the movable block 5 respectively. The rotary connection mechanism includes a knob 9, a rotating rod 10, a connecting piece 11 and a connecting box 12. The knob 9 is installed on the main body 2 and is rotatably connected to the main body 2. The rotating rod 10 is fixedly installed at the bottom of the knob 9. The connecting piece 11 is fixedly installed on the rotating rod 10. The connecting box 12 is installed inside the main body 2 and is detachably connected to the connecting piece 11.

[0028] In this embodiment, the wire contact mechanism includes a fixed block 3, a fixed contact rod 4, a movable block 5, a movable contact rod 6, a first spring 7, and a limiting rod 8. When in use, the wire is inserted into the fixed block 3 and contacts the fixed contact rod 4. At this time, when the movable block 5 is pressed down, the movable contact rod 6 fixedly connected to the movable block 5 is in a crisscross pattern with the fixed contact rod 4, firmly connecting and clamping the wire. During the downward movement of the movable block 5, the limiting rod 8 slides inside the first guide rail 21, thereby restricting the displacement of the movable block 5. At this time, the first spring 7 is stressed and squeezed to both sides. Remove the limiting pin 24 located on the movable block 5 and install it inside the fixed block 3. Due to the acting force of the first spring 7, the two will be firmly connected, thereby implementing the contact and connection of the wire.

[0029] In this embodiment, the rotary connection mechanism includes a knob 9, a rotating rod 10, a connecting piece 11, and a connecting box 12. When in use, twist the knob 9, and the rotating rod 10 fixedly connected to the knob 9 rotates in the second guide rail 22, thereby driving the connecting piece 11 to rotate. During the downward rotation of the rotating rod 10, the connecting piece 11 contacts the connecting box 12, and the contact piece 17 inside the connecting box 12 and the second spring 18 generate deformation displacement after receiving the downward pressure of the connecting piece 11. During this process, the connecting piece 11 is tightly connected to the contact pieces 17 on both sides. After the connection, disconnection is required. At this time, the automatic disconnection mechanism starts to operate. The automatic disconnection mechanism includes a driving motor 13, a driving gear 14, and a driven gear 15. A through hole 16 is provided on the driven gear 15. During the rotation of the rotating rod 10, since the rotating rod 10 rotates downward, the rotating rod 10 is inserted into the through hole 16 inside the driven gear 15, and the driven gear 15 rotates accordingly. At this time, disconnection is implemented. The driving motor 13 rotates, driving the driving gear 14, and the driven gear 15 meshing with the driving gear 14 rotates accordingly, thereby driving the rotating rod 10 to rotate. Rotate the knob 9 to the original position as described above. At this time, the connecting piece 11 slides out of the connecting box 12, realizing the disconnection between the connecting piece 11 and the contact piece 17.

[0030] In this embodiment, when the main body 2 is installed inside the outer housing 1, a positioning rod 19 is installed on the outer housing 1. A wing nut 20 is fixedly installed at the top of the positioning rod 19. A wire hole 23 is provided on the external housing. When in use, press the main body 2 into the external housing at this time. The wire hole 23 in the external housing is in the same position as the fixed block 3 on the main body 2. At this time, rotate the wing nut 20. The wing nut 20 is fixedly connected to the positioning rod 19 installed inside the outer housing 1. After rotation, the limiting rod 8 locks the main body 2, so that it is fixedly placed inside the external housing.

[0031] In summary, when in use, first install the main body 2 in the external housing, press the main body 2 into the external housing, and the wire hole 23 in the external housing is in the same position as the fixing block 3 on the main body 2. At this time, rotate the wing nut 20. The wing nut 20 is fixedly connected to the positioning rod 19 installed inside the outer housing 1. After rotation, the limiting rod 8 then blocks the main body 2, so that it is fixedly placed inside the external housing. At this time, connect the wire to the main body 2 through the wire hole 23, insert the wire into the fixing block 3, and contact the fixed contact rod 4. At this time, press down the movable block 5, and the movable contact rod 6 fixedly connected to the movable block 5 is in a jagged state with the fixed contact rod 4, firmly connecting and clamping the wire. During the downward movement of the movable block 5, the limiting rod 8 slides inside the first guide rail 21, thereby restricting the displacement of the movable block 5. At this time, the first spring 7 is forced to squeeze to both sides, remove the limiting pin 24 on the movable block 5, and install it inside the fixing block 3. Due to the acting force of the first spring 7, the two will be firmly connected, so as to implement the contact and connection of the wire. The movable contact rod 6 and the fixed contact rod 4 are electrically connected to the connection box 12 inside the main body 2. At this time, the connection between the main body 2 and the external circuit is already on. When we need to use the electrical appliance, turn the knob 9, and the rotating rod 10 fixedly connected to the knob 9 rotates in the second guide rail 22, thereby driving the connecting piece 11 to rotate. During the downward rotation of the rotating rod 10, the connecting piece 11 contacts the connection box 12, and the contact piece 17 inside the connection box 12 and the second spring 18 generate deformation displacement after receiving the downward pressure of the connecting piece 11. During this process, the connecting piece 11 is firmly connected to the contact pieces 17 on both sides. If not at home and need to cut off the contact, send a signal at this time, and the cut-off mechanism that receives the signal starts to operate. During the rotation of the rotating rod 10, since the rotating rod 10 rotates downward, the rotating rod 10 is inserted into the through hole 16 inside the driven gear 15, and the driven gear 15 then rotates accordingly. At this time, cut off the contact. The drive motor 13 rotates, driving the driving gear 14, and the driven gear 15 meshing with the driving gear 14 then rotates accordingly, thereby driving the rotating rod 10 to rotate. Rotate the knob 9 to the original position as described above. At this time, the connecting piece 11 slides out of the connection box 12, realizing the cut-off between the connecting piece 11 and the contact piece 17, so as to complete the switching use of the remote household electrical appliance.
