An intelligent detection and alarm device that is convenient for maintenance

Abstract

The present invention is applicable to the technical field of alarms, and provides a convenient maintenance intelligent detection alarm, comprising: a housing, the bottom of which is provided with mounting legs, and the bottom of the housing is provided with a smoke inlet channel; the filter assembly includes: filter screen and labyrinth column; detection assembly, which is fixedly connected inside the housing, and the detection assembly includes: circuit board, light source and light source receiver; cleaning assembly, which is fixedly connected to the housing, and the cleaning assembly is located at Above the light source and the light source receiver, the cleaning assembly includes: a rocker, two wipers arranged symmetrically with respect to the rocker, and a connecting rod. In this way, the present invention advances the alarm time by changing the position of the smoke inlet passage, and at the same time changes the installation method of the filter screen and the labyrinth cover, so as to realize the quick disassembly of the filter screen and the labyrinth cover, and adds a cleaning component. The light source and light receiver are automatically cleaned while the cover is closed, making subsequent maintenance more convenient.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to an intelligent detection alarm which is convenient for maintenance. Background technique [0002] Along with modern hotel, restaurant, place of entertainment and family etc. use fire, the increase of electricity consumption, the frequency that various fires take place is more and more higher. In order to be able to detect early and avoid significant loss of life and property, people are now generally equipped with fire alarm devices. The fire alarm uses the highly sensitive detection elements installed inside to capture abnormal changes in temperature and gas content in the air and send out alarm signals. The above-mentioned fire alarms are generally installed on the ceiling, and the early warning range of a single alarm is limited, and a large number of alarms are often installed in a building. [0003] But the structure of existing fire alarm has the following disadvantages: t...

AI Technical Summary

Problems solved by technology

[0003] But the structure of existing fire alarm has the following disadvantages: the alarm is generally installed upside down on the ceiling, and when a fire occurs, the smoke needs to gather a certain thickness on the ceiling to enter the fire alarm, delaying the alarm time; and after long-term use , Dust, dust, and smoke particles around the fire alarm will enter the sensing area from the opening on the shell. If used for a long time, the detection element will be insensitive and affect the detection effect.

There are two ways to clean the fire alarm: cleaning after disassembly or self-cleaning. In actual use, the cleaning effect of self-cleaning is not ideal, the structure is complicated, and the failure rate is high.

The method of cleaning after disassembly can effectively clean the dust on the filter screen and the labyrinth cover. The cleaning effect is good, but it is laborious to disassemble, and the work efficiency of the workers is low. At the same time, the installation position of the detection element is relatively hidden, and the dust on the surface of the detection element cannot be effectively detected. cleaning up

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
