The weak magnetic fan can circulate indoor air, and the air sterilization effect and efficiency are improved.
The unit of disinfecting is imitated by force for disinfect to indoor contact surface and air when nuclear magnetic resonance room does not use, imitate the ultraviolet disinfector that the structure that the unit of disinfecting includes this company's production is similar with application number 201810339297.2 by force, its power is 360W generally, and it is faster to adopt the speed of disinfecting behind the great power. As shown in fig. 4, the ultraviolet sterilizer is placed on the ground, and has three ultraviolet lamps 3, each of which is provided with an aluminum reflector 9 and a wheel 8 at the bottom thereof, so that the ultraviolet sterilizer can be moved to a desired position in a targeted manner to further improve the sterilization effect. And the parts of the ultraviolet sterilizer except the ultraviolet lamp tube are mainly made of non-magnetic materials, including but not limited to aluminum and copper.
The monitoring unit comprises a first inductor and a second inductor, the first inductor is arranged at the powerful sterilization unit or any indoor position capable of monitoring the whole field and is used for detecting whether human activities exist in the nuclear magnetic resonance chamber; the second sensor 10 is arranged on the continuous circulation sterilization unit and used for detecting whether human activities are in the position around the continuous circulation sterilization unit, mainly close to the bottom; the first sensor and the second sensor are sensors capable of detecting whether people exist, and include but are not limited to infrared sensors and human body microwave sensors, and the two sensors transmit detected information to the control unit in real time.
