The working principle of the medical pager is the called user receiver in the wireless paging system. It consists of superheterodyne receiver, decoder, control and display. It selects the useful signal to be received from the paging signal and interference transmitted by the base station, restores it to the baseband signal of the original paging machine, and generates audio (or vibration) and digital (or letter, Chinese character) messages. The BP machine has two modes of manual tandem and automatic tandem, and the corresponding paging stations are called manual paging stations and automatic paging stations. The manual paging station needs manual operation to encode these information and send signals through the transmitter. According to the line number of the incoming phone, the automatic paging station automatically finds out the caller's phone number and sends it out at the same time, so that the callee can know which phone is calling. Pagers often used are divided into two categories: digital pagers and Chinese pagers. Digital pager is small, cheap and practical. The Chinese pager displays Chinese characters directly, and the information is easy to recognize.

Negative ions can quickly neutralize positive ions such as coke smoke, second-hand smoke, oil smoke, etc. in the air, so negative ion energy-saving lamps can purify harmful gases and smoke, make non-toxic reactions in the air and fall down after differentiation, achieving perfect air purification. In the clean technology of air conditioning products, negative ions can effectively remove trace harmful gas molecules in the air, improve indoor air quality, and provide healthy and comfortable indoor environment for indoor personnel. At the same time, the anion can effectively remove the leather smell, smoke smell and other odor in the closed car compartment, making the journey of the personnel in the car more pleasant. When negative ions are used, they can reduce the harm of radiation to human body. Computer users can also inhale sufficient negative ions in the process of use, refreshing and refreshing.

The current room air quality score will be displayed on the display screen of the air purification and disinfection device, and many consumers only pay attention to this score table. If they think that the standard is met, it means that the air purification and air disinfection are completed, without considering other air pollutant factors, which is obviously a mistake of many consumers. Because a room cannot be a separate individual, it is often adjacent to the kitchen and bathroom. If you only pay attention to the current air quality score and feel that it meets the standard, you can turn off the air purification sterilizer. What if it is infected by the air pollutants in the kitchen and bathroom? Therefore, we should not only focus on the air quality fraction, but also on the air purification and air disinfection of each room or space.

Whether a filter type air purification and disinfection machine is professional or not, the filter screen is the key. The principle is to suck air into the machine and let the air pass through the filter screen. The filter screen filters the carrier dust of bacteria and viruses, including some harmful substances, and sends clean air out. The material of the filter screen, whether it is thick enough, whether it is antibacterial, and how large the dust capacity are all directly related to its purification effect. During daily maintenance, pay attention to regularly cleaning or replacing the filter screen to avoid the filter screen becoming a hotbed of bacteria and viruses and causing secondary pollution.
