Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-3, the portable smoke detector detecting device of the present invention includes a smoke generator 1 and a smoke collecting hood 2. The smoke generator 1 is communicated with the smoke collecting cover 2 through a smoke conveying pipe 3, the smoke conveying pipe 3 is provided with a regulating valve 4, and the smoke conveying pipe 3 positioned between the regulating valve 4 and the smoke collecting cover 2 is provided with a sensor mounting interface 5 for mounting a smoke concentration sensor so as to detect the smoke concentration in the smoke conveying pipe 3. The regulating valve 4 is used for controlling the smoke volume entering the smoke collecting hood 2. The smoke collecting cover 2 is internally provided with a smoke disturbing plate 6 which divides the smoke collecting cover 2 into an upper space and a lower space, and the smoke disturbing plate 6 is provided with a plurality of smoke outlet holes 7.

Specifically, a plurality of smoke outlets 7 are uniformly arranged on the smoke disturbing plate 6, and the aperture of the smoke outlets 7 is smaller than the inner diameter of the smoke conveying pipe 3. When the flue gas enters the smoke collecting hood 2 and impacts on the smoke disturbing plate 6, the flue gas is dispersed in the space below the smoke disturbing plate 6 under the blocking of the smoke disturbing plate 6. Because the smoke continuously enters the space below the smoke disturbing plate 6 from the smoke conveying pipe 3, the pressure in the smoke conveying pipe is larger than the pressure in the space above the smoke disturbing plate 6, the smoke enters the smoke collecting hood 2 above the smoke disturbing plate 6 through the smoke outlet 7 on the smoke disturbing plate 6, and therefore the smoke is scattered in the space above the smoke collecting hood 2, and a smoke scene in a fire is simulated.

When the smoke collecting hood is used, the smoke sensing detector is directly covered by the smoke collecting hood 2, so that a closed detection environment is formed, and the influence of environmental wind in the detection process is avoided. Then starting the smoke generator 1 to generate smoke, and controlling the smoke output amount through the regulating valve 4 to enable the smoke output amount to meet the alarm requirement of the smoke detector, so as to avoid the influence on the detection result caused by too large or too small smoke output amount. After the flue gas entered into collection petticoat pipe 2 along defeated tobacco pipe 3, disturbing blocking of cigarette board 6 down, the flue gas can not directly dash to smoke detector, but spreads in collection petticoat pipe 2, forms the smog environment like during the scene of a fire to realized simulating the scene of fuming when conflagration, avoided the problem that prior art open detection mode exists, great improvement the degree of accuracy and the reliability that detect.

Preferably, the smoke conveying pipe 3 is a transparent pipe body, so that a tester can observe the concentration of smoke in the smoke conveying pipe 3 in real time, and can adjust the smoke concentration in time.

Wherein, it is the umbelliform arc to disturb cigarette board 6, and the middle depressed part orientation of disturbing cigarette board 6 defeated tobacco pipe 3 goes out the mouth direction to make the flue gas when strikeing and disturbing cigarette board 6, the flue gas can upwards scatter along the lateral wall that disturbs cigarette board 6, and discharge by cigarette outlet 7 at the in-process that scatters, be favorable to reducing the flue gas to disturbing the impact of cigarette board 6, and also do benefit to the discharge of flue gas.

Be equipped with a holding ring 8 on the lateral wall of collection petticoat pipe 2 of this embodiment, the top of holding ring 8 is equipped with a plurality of spacing archs 9, disturbs cigarette board 6 joint in the grafting clearance that comprises holding ring 8 and spacing archs 9, has realized will disturbing cigarette board 6 and has installed in collection petticoat pipe 2. And the connection mode through the joint makes the cigarette disturbing plate 6 easy to detach, and is convenient for maintenance.

Preferably, collection petticoat pipe 2 is transparent tubbiness collection petticoat pipe, and the inspection personnel of being convenient for observe the flue gas condition in collection petticoat pipe 2.

Preferably, a smoke exhaust interface 10 is arranged below the smoke collecting cover 2 and used for exhausting smoke in the smoke collecting cover 2. In some spaces with more smoke detectors or poor ventilation, smoke is difficult to disperse after detection, and can be stored for a long time, so that the smoke detector is not beneficial to normal use in the place. In order to solve the problem, after the detection device is used for detecting a smoke detector, the smoke detector is continuously kept in a closed state, a smoke exhaust pipe is arranged on the smoke exhaust interface 10, smoke in the smoke collection cover 2 is quickly exhausted through a smoke exhaust machine, and therefore the smoke during detection is prevented from remaining in the space. When smoke is not required to be discharged, the smoke discharging interface 10 can be directly sealed through a plug, and the smoke discharging device is simple and convenient to use.

Preferably, the end of the smoker 1 is provided with a connector 11 for screwing the extension rod. To installing higher smoke detector, can install extension bar on connector 11 and realize the detection to smoke detector, need not with the help of instruments such as double ladder, make things convenient for the detection of measurement personnel to smoke detector more.

The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which will not affect the utility of the effect patent of the present invention.
