Description

Technical Field

[0001] The utility model belongs to the technical field of induction switches, in particular to a three-stage double-throw infrared induction switch. Background Art

[0002] The infrared sensor switch is an automatic control switch based on passive infrared sensing technology. The main sensing device is the human body pyroelectric infrared sensor. The human body temperature is generally 37°C, and it will emit infrared rays with a wavelength of about 10μm, while the temperature around the human body is generally lower than 37°C. The pyroelectric infrared sensor contains two pyroelectric elements connected in series or in parallel, which are very sensitive to infrared radiation with a wavelength range of 0.2 to 20μm. When the human body moves within the sensing range of the infrared sensor switch, the infrared radiation received by the two elements is different and constantly changing. The sensor outputs the sensing signal, which is amplified by the circuit to achieve the purpose of controlling the circuit. Infrared sensor switches are usually used for automatic control of street light switches in public places, such as schools, hospitals, office buildings, etc. They are also widely used in homes, such as lighting control in corridors, toilets, kitchens, etc. In addition, infrared sensor switches can also be used to control equipment such as automatic doors and burglar alarms.

[0003] In the prior art, the two electric elements of the pyroelectric infrared sensor are structured in opposite directions to suppress the interference caused by the increase in their own temperature. When the human body is stationary within the sensing range, the pyroelectric effect is offset to a fixed value, and the sensor has no signal output; only when the human body moves within the sensing range, the infrared radiation received by the two electric elements is different and constantly changing, and the sensor outputs a sensing signal.

[0004] After long-term use and observation, it was found that the existing infrared sensor switches on the market do not have a three-speed switch. If the power is kept on all the time, there will be power loss. If the power is not kept on all the time, the light time cannot be maintained for a long time.

[0005] To this end, the utility model provides a three-stage double-throw infrared induction switch. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one problem raised in the background technology, a three-speed double-throw infrared induction switch is proposed.

[0007] The technical solution adopted by the utility model to solve its technical problem is: the three-speed double-throw infrared induction switch described in the utility model comprises a switch group; one end of the switch group is electrically connected to a live wire, and the other end is electrically connected to an infrared induction switch; the other end of the infrared induction switch is electrically connected to an electrical device; the other end of the electrical device is electrically connected to a neutral wire.

[0008] Preferably, the switch group includes a first knife switch; the A2 interface in the first knife switch is electrically connected to the live wire; the A3 interface in the first knife switch is electrically connected to the live wire interface of the infrared sensing switch; and the neutral wire interface of the infrared sensing switch is electrically connected to the electrical equipment.

[0009] Preferably, the switch group includes a first knife switch and a second knife switch; the A2 interface in the first knife switch is electrically connected to the live wire; the A1 interface in the first knife switch is electrically connected to the B1 interface in the second knife switch; the A3 interface in the first knife switch is electrically connected to the infrared sensing switch and the live wire interface; the B2 interface in the second knife switch is electrically connected to the electrical equipment; the B3 interface in the second knife switch is electrically connected to the neutral wire interface of the infrared sensing switch.

[0010] The beneficial effects of the utility model are as follows:

[0011] The three-speed double-throw infrared induction switch described in the utility model is an infrared induction switch with a single-pole double-throw switch or a double-pole double-throw switch added. A three-speed switch can be added to the infrared induction switch to add a three-speed function, so that the staff or users can switch the power-on status of the electrical equipment according to the usage scenario and switch the gears at will, which is convenient and practical, reduces the situation where the electrical equipment is kept in the power-on state and causes power loss, and reduces the situation where the power is not kept in the power-on state and the lighting time cannot be maintained for a long time.
