Technical Field

The invention relates to air disinfection equipment, in particular to an ultraviolet air disinfector with a backup light source and a control method thereof.

Background

In recent years, air pollution has increased and the living standard of people has improved. A large amount of indoor decoration and chemical products are used; indoor air quality in public places as well as in private homes is increasingly poor. Therefore, a series of air purification measures are carried out: activated carbon adsorption, chemical reagent oxidation, ozone oxidation, nano-photocatalyst treatment, and the like. The active carbon has short service cycle and is easy to reach saturation, and the use of chemical reagents and ozone is easy to cause secondary pollution. The nanometer photocatalyst is more and more popular among people as a safe, simple and effective technology.

The nano photocatalyst products adopted in the current market are mainly divided into two types: photocatalyst emulsion and photocatalyst plate. When in use. The ultraviolet lamp tube is used for irradiating the photocatalyst, so that the photocatalyst is activated by ultraviolet light to be forced to react with air, and the effects of purifying and disinfecting the air are achieved. However, the conventional disinfection lamp for medical use is generally operated for 1000 hours at 800-.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a take ultraviolet ray air disinfector of back-up light source which characterized in that: it includes air disinfector body 1, and locates photocatalyst filter screen 2 and fan in it, and after the fan absorbed the air from the external world, the air was discharged from the air outlet after the filtration and the disinfection of photocatalyst filter screen 2, photocatalyst filter screen 2 top install first ultraviolet banks 3 and second group ultraviolet banks 4, first ultraviolet banks 3 inserts power module after being connected with first relay, inserts power module after second ultraviolet banks is connected with the second relay, power module still electric federation control MCU and detection module and alarm module, control MCU control first relay and second relay work.

The first ultraviolet lamp group 3 and the second ultraviolet lamp group are formed by connecting a plurality of ultraviolet lamp tubes in parallel.

The ultraviolet lamp tubes of the first ultraviolet lamp group 3 and the second ultraviolet lamp group are distributed at intervals.

The detection module is a current transformer arranged on the first ultraviolet lamp group 3 and the second ultraviolet lamp group and used for detecting the current of the lamp groups during working.

A control method of an ultraviolet air sterilizer with a backup light source comprises the following steps:

a, the control module is connected with a first relay and detects the working current of a first lamp group;

b: when the working current of the first lamp group is detected to deviate from a set value, the first relay is switched off, and the second relay is switched on;

c: after the second relay is switched on, the working current of the second lamp set is detected;

d: when the working current of the second lamp set is detected to deviate from the set value, the first relay is switched on, so that the first relay and the second relay work simultaneously, and a fault signal is sent to the alarm module, so that the alarm module sends an alarm indication.

The working principle is as follows: when producing this air disinfector, be the interval distribution installation with two sets of ultraviolet tube, during normal use, control system starts first banks through first relay and carries out work, at first banks working process, through current detection's mode real time monitoring this banks's operating condition. When one or more lamps in the lamp set are damaged, the working current of the lamp set is deviated. When the deviation value is larger than the set value, the lamp set is seriously damaged. The system switches on the second relay by switching off the first relay, so that the second lamp set works. And detects the operating current of the second lamp set. Because the lamp tubes of the first and second lamp sets are distributed at intervals, the ultraviolet radiation effect on the photocatalyst filter screen 2 can be ensured. When the working current of the second lamp group is detected to be deviated, the fact that the lamp tubes in the lamp group are damaged is indicated, at the moment, the control system is connected with the first relay and the second relay simultaneously, the first lamp group and the second lamp group work simultaneously, the lamp tubes which are not damaged in the two groups of lamps continue to work, and the air sterilizer can continue to work. Meanwhile, the control system sends an alarm instruction to the alarm module to remind a user of maintaining the alarm module. Theoretically, the service life of the air sterilizer can be more than 3 times of that of the traditional air sterilizer, so the air sterilizer can be widely popularized and used.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
