[0014] In order to make the technical means, creative features, achieved purposes and functions of the present invention clearer and easier to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners:

[0015] The present invention provides a sensing switch, including a switch body 1. The switch body 1 has a window 2 with an opening facing the side. An induction sensor 3 capable of sensing a limb is provided on the inner wall of the window 2. The induction sensor 3 is an inductor in the prior art that can sense a human hand. The induction sensor 3 is connected to a controller built into the switch body 1. The controller is used to control the turning on or off of a lamp. A groove is provided in the window 2, and a slider 4 is provided in the groove. The slider 4 is connected to a strip member 5. The strip member 5 extends into a sliding cavity 6 of the switch body 1. A gear set 8 and a retracting mechanism 7 in the prior art are installed in the switch body 1. The retracting mechanism 7 is the same as the internal structure of a tape measure in the prior art. The retracting mechanism 7 is connected to the gear set 8. The gear set 8 is formed by multiple gears meshing with each other. The gear set meshes with the strip member 5. A first contact piece is provided on the side of the slider 4, and a second contact piece 9 capable of contacting the first contact piece is provided on the inner wall of the groove. When the first contact piece contacts the second contact piece 9, the retracting mechanism 7 is in a state with elastic force. At the same time, the controller is connected to the induction sensor 3 and controls its operation. When the retracting mechanism 7 is in a natural state, the first contact piece is separated from the second contact piece 9, and the controller is connected to the induction sensor 3 and controls it to close. The controller is in the prior art. When the induction sensor 3 senses a human hand, it controls the corresponding lamp to turn on. When it senses a human hand again, the controller controls the corresponding lamp to turn off, so as to turn the lamp on and off by sensing the hand. The switch body 1 is connected to a power supply, that is, the processor, the controller and the sensor are all connected to the power supply. The processor is connected to the controller and the sensor. The controller is electrically connected to the lamp installed in this room to control the turning on and off of the lamp in this room.

[0016] Before starting work every day, the staff member presses the slider 4 to push the strip 5 connected thereto towards the sliding cavity 6 until the end of the strip 5 contacts the innermost side of the sliding cavity 6. At this time, the rewinding mechanism 7 generates an elastic force, and the first contact piece contacts the second contact piece 5 to turn on the operation of the induction sensor 3; when in use, the hand reaches into the window 2 and then turns on or off the lamp controlled by the controller. When the rewinding mechanism 7 is rewinding, the first contact piece and the second contact piece 5 are always in contact, so the induction sensor 3 is operating. When the rewinding mechanism 7 finishes rewinding and there is no elastic force, the first contact piece just separates from the second contact piece 9, and the operating state of the induction sensor 3 is turned off and it no longer has the induction function. When setting the elastic force of the rewinding mechanism 7, it is designed according to the daily usage of the lamp. For example, when it is required to work for 12 hours, the rewinding mechanism 7 and the gear set 8 cooperate with each other to make the rewinding mechanism 7 rewind until the elastic force disappears in 12 to 13 hours.

[0017] The rewinding mechanism 7 includes a tape measure assembly 10 installed in the switch body 1. The internal structure of the tape measure assembly 10 is the same as that of the existing tape measure and includes a coiled spring 15 with elasticity. The tape measure assembly 10 is connected with a connecting column 11. The cross-section of the connecting column 11 is plum blossom-shaped. A sliding sleeve 12 that can slide up and down is sleeved on the connecting column 11. A plum blossom protrusion 13 is provided at the lower end of the sliding sleeve 12. A plum blossom groove 14 that can be engaged with the plum blossom protrusion 13 is provided on the surface of the switch body 1; when it is necessary to adjust the rewinding time of the rewinding mechanism 7, the sliding sleeve 12 is pulled out upwards to separate it from the plum blossom groove 14, and then the sliding sleeve 12 is rotated to drive the connecting column 11 to rotate, thereby driving one end of the coiled spring connected to the connecting column 11 to rotate, so that the rewinding elastic force of the tape measure assembly 10 is changed, thereby changing the time until the elastic force disappears when the rewinding mechanism 7 rewinds; when the connecting column 11 rotates, the position of the entire tape measure assembly 10 is changed, and the end of the coiled spring is fixedly wound on the connecting rod connected to the end gear of the gear set 8.

[0018] A mechanical switch 24 is provided on the switch body 1. The mechanical switch 24 is electrically connected to the lamp in the room and is used for emergency situations.

[0019] A row of teeth is provided on the lower surface of the strip 5 and meshes with the gear set 8 installed in the switch body 1, so that when the gear set 8 operates, it can drive the strip 5 to slide left and right. The gear set 8 is composed of multiple meshing gears. The gear at the driving end of the gear set 8 is connected to the rewinding mechanism 7 through a connecting piece. When the rewinding mechanism 7 moves to the innermost side of its sliding cavity 6, it generates an elastic force that can rebound.

[0020] The groove is located on the left side of the window 2. A baffle 19 is provided at the opening of the groove. The baffle 19 and the inner wall of the groove form a sliding cavity 20 for sliding the slider 4. The baffle 19 has a perforation 25. The inner diameter of the perforation 25 is 5 cm to 15 cm. The pen 22 can pass through the perforation 25 to push the slider 4 to move in the direction of the chute. The slider 4 can move left and right in cooperation with the groove. The first contact piece is inlaid on the upper surface of the slider 4, and the second contact piece 9 is inlaid on the inner wall of the groove. The first contact piece and the second contact piece 9 are connected to the induction sensor 3.

[0021] As a specific embodiment, the rewinding mechanism 7 and the gear set 8 are matched, and the principle is the same as that when the children's toy car moves backward a certain distance and then is released and can move forward a certain distance. Drawing on the principle of the prior art, the switch body 1 has an installation cavity 10 for installing the rewinding mechanism 7.

[0022] An active wheel 16 and a driven wheel 17 are installed in the sensing switch. A protective film is wound around the active wheel 16 and the driven wheel 17. The perforation 25 is misaligned with the position of the protective film, so that it is convenient for an object to pass through the perforation 25. The controller is connected to the motor connected to the active wheel 16. By controlling the rotation of the active wheel 16, the protective film protects the inner side of the window 2 to reduce infection. A plurality of rotating wheels 18 are installed on the switch body 1. The protective film 21 is steered by the plurality of rotating wheels 18 and straddles the rotating wheels 18.

[0023] An indicator light 23 is provided at the bottom of the window 2. The indicator light 23 is connected to the controller. The controller is connected to a processor provided in the switch body 1. The processor can record the long-on time of the indicator light 23. The processor is connected to a display provided on the switch body 1. The display shows the long-on time of the indicator light 23.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
