Abstract

The invention discloses a smoke detector testing device, which comprises a fixed end of a smoke column, a handle bar and a multi-section telescopic joint detachably connected with the handle bar. A fan and a battery compartment are arranged in the handle bar. The battery compartment is equipped with a battery, and the telescopic joint The first and last ends of the handle are respectively provided with an inner wire sleeve and an outer wire sleeve that cooperate with each other. The front end of the handle rod is provided with an inner wire sleeve. Shaped structure, the fixed end of the smoke column can be inserted into the inner wire sleeve of the expansion joint. In the present invention, incense sticks are arranged in the fixed end of the smoke column, and the fixed end of the smoke column and the handle rod are respectively arranged at the first and last ends of the multi-section assembled expansion joint, and the smoke of the incense stick is blown by using the fan and the ventilation hole arranged in the handle rod. To the smoke detector that needs to be detected, there is no secondary pollution to the smoke detector, and different numbers of expansion joints can be selected according to the distance from the smoke detector. The structure is simple, easy to implement, and easy to operate.

Description

A smoke detector testing device

technical field

The invention relates to a tester, in particular to a smoke detector testing device.

Background technique

Generally, the ignition process of a fire is accompanied by three combustion products: smoke, heat and light. In the early stage of the fire, due to the low temperature, most of the substances are in the smoldering stage, so a lot of smoke is produced. Smoke detectors are developed using this feature, and they are also called smoke detectors, smoke detectors, smoke detectors, smoke detectors and smoke sensors, which detect changes in the concentration of smoke A device that converts electrical signals to achieve alarm purposes. Smoke detectors are mainly used in fire protection systems and security systems. They have the characteristics of high sensitivity, stability and reliability, low power consumption, beautiful and durable, and easy to use. They are fire detectors that can respond to visible or invisible smoke particles. Due to the high sensitivity of the smoke detector, it needs to be debugged during the installation process, and the inspection and acceptance process after installation is very troublesome, time-consuming and labor-intensive.

Contents of the invention

The purpose of the present invention is to provide a smoke detector testing device, which can conveniently and quickly test the sensitivity of the smoke detector.

The present invention adopts following technical scheme:

A test device for a smoke detector, including a fixed end of a smoke column, a handle rod and a multi-section telescopic joint detachably connected to the handle rod, a fan and a battery compartment are arranged inside the handle rod, batteries are installed in the battery compartment, and the first and last ends of the telescopic joint are There are inner wire sleeves and outer wire sleeves that cooperate with each other respectively. The front end of the handle rod is provided with an inner wire sleeve. The fixed end can be inserted into the inner wire sleeve of the expansion joint.

A smoke column fixing screw is also arranged on the fixed end of the smoke column.

In the present invention, incense sticks are arranged in the fixed end of the smoke column, and the fixed end of the smoke column and the handle rod are respectively arranged at the first and last ends of the multi-section assembled expansion joint. For the smoke detector that needs to be detected, there is no secondary pollution to the smoke detector, and different numbers of expansion joints can be selected according to the distance from the smoke detector. The structure is simple, easy to implement, and easy to operate.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention includes a smoke column fixed end 1, a handle bar 2 and a multi-section telescopic joint 3 detachably connected with the handle bar 2, and the handle bar 2 is provided with a fan 4 and Battery compartment 5, batteries are housed in battery compartment 5, internal wire sleeves 6 and outer wire sleeves 7 that cooperate with each other are respectively provided at the first and last ends of expansion joint 3, inner wire sleeves 6 are provided at the front end of handle rod 2, and inner wire sleeves 6 of handle rod 2 are provided. 4 The front end and the expansion joint 3 are provided with a vent hole 8 through the end. The fixed end 1 of the smoke column is a hollow cylindrical structure. The fixed end 1 of the smoke column is also provided with a set screw 9 for the smoke column. Silk sleeve6.

When in use, the multi-section expansion joint 3 can be assembled with the inner wire sleeve 6 and the outer wire sleeve 7, and the handle rod 2 is installed on the tail end of the multi-section expansion joint 3, and the smoke column fixed end 1 is installed on the multi-section expansion joint 3 head end. After igniting the incense stick, insert it into the fixed end 1 of the smoke column, and fix the incense stick with the smoke column fixing screw 9 . After the fan 4 inside the handle rod 2 is working, the wind can be blown out from the fixed end 1 of the smoke column through the front end of the fan 4 inside the handle rod 2 and the vent hole 8 through the telescopic joint 3 to blow out the wind from the first end of the fixed end 1 of the smoke column, and the incense produced by the stick can be blown out. The smoke blows the direction of the smoke detector that the user needs to test to test whether the smoke detector is working normally and whether the response is sensitive. The smoke emitted by the present invention has no open flame, no soot, no smoke oil, no secondary pollution to the smoke detector, and different numbers of expansion joints 3 can be selected according to the distance from the smoke detector.
