Description

Technical Field

[0001] The present invention relates to the technical field of smoke sensor detection, in particular to a smoke sensor detection device. Background Art

[0002] The detection device of the smoke sensor is a device for performing functional detection on the smoke sensor. The commonly used detection device of the smoke sensor generates smoke to detect whether the sensing function of the smoke sensor in a smoky environment is qualified. However, the current detection device of the smoke sensor cannot control the smoke concentration, making it unable to adapt to the diversity of detection products and environments. In addition, the detection device often has a poor reaction effect when performing a chemical reaction to generate smoke. At the same time, the chemical reactant remains in the reaction device after the reaction, which will affect the detection device.

[0003] The patent with application number CN202120204021.0 discloses a detection device for a smoke sensor, which has the beneficial effects of simple structure, easy operation, high detection efficiency, and is suitable for detection of smoke sensors of different specifications, thereby improving production efficiency and reducing production costs. The device itself is simple to manufacture and low in cost, and is easy to promote. The device for detecting a smoke sensor described in the utility model ensures the sealing of the device by setting a first sealing ring, a second sealing ring and a sensor power port, thereby ensuring a stable, safe and reliable test environment. Although the patent solves the above-mentioned problems, there are still problems such as uncontrolled smoke concentration, uneven smoke reaction, and failure to clean up the residual chemical reactants on the inner wall of the reactor. Therefore, it is very necessary to design a detection device that is highly practical and can control the smoke concentration, make the smoke reaction more uniform, and remove the residual reactants. Summary of the invention

[0004] The object of the present invention is to provide a detection device for a smoke sensor to solve the problems raised in the above background technology.

When the smoke enters the conical smoke chamber, the rotation direction of the two-way fan is adjusted according to the required smoke concentration to pressurize or absorb the smoke. When the smoke is compressed, it converges to the smoke nozzle to increase its concentration. When a part of the smoke is absorbed, the smoke in the conical smoke chamber becomes less and the concentration decreases.

[0024] Working principle: When smoke enters the conical smoke chamber 310, the rotation direction of the two-way fan 22 is adjusted according to the required smoke concentration to pressurize or absorb the smoke. When the smoke is compressed, it converges to the smoke nozzle 311 to increase its concentration. When a part of the smoke is absorbed, the smoke in the conical smoke chamber 310 becomes less and the concentration decreases. In the process of smoke entering the conical smoke chamber 310 from the smoke outlet 45, the crank 31 drives the shaft 32 to rotate back and forth, thereby causing the driving turntable 33 to rotate back and forth.

When a certain amount of smoke in a certain space is squeezed by pressure, the activity space becomes smaller and the concentration becomes higher. On the contrary, when it is extracted, the activity space becomes larger and the concentration becomes lower. The larger the diameter of the sliding telescopic plate 35, the more smoke is discharged. The smaller the diameter, the less smoke is discharged. The more smoke is squeezed together, the higher the concentration is. The less smoke is dispersed everywhere, the lower the concentration is, so that the smoke concentration control is more accurate.

[0025] Before smoke is emitted, a chemical reaction is required to generate smoke. At this time, the motor 41 is started to work, the output shaft 42 rotates, and the stirring paddle 44 is driven to rotate. While the stirring paddle 44 rotates, the output shaft 42 drives the driving gear 46 to rotate. The driving gear 46 meshes with the crown gear 47 to make the rotating rod 48 rotate itself.
