Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of smoke temperature detection equipment, specifically a device for testing smoke temperature probes. Background Technology
[0002] A smoke temperature probe testing device is a specialized device for performance testing and evaluation of smoke temperature probes. A smoke temperature probe gun is one such device. By simulating different concentrations of smoke and corresponding temperature environments, it verifies whether the smoke temperature probe's response sensitivity, alarm threshold, response time, and other key indicators are accurate and reliable under different smoke and temperature conditions. It is typically used after the smoke temperature probe is installed to verify whether it can operate normally.
[0003] In use, hot air or smoke is blown out by opening the smoke temperature detection nozzle. Then, through the connection of multiple rods, the smoke temperature detection nozzle blows air into the reserved hole of the smoke temperature probe. When the smoke temperature probe receives hot air or smoke, an alarm is triggered.
[0004] However, in actual use, the working environment may include outdoor installation, especially in environments such as the outside of ship cabins, the facades of high-rise buildings, large stadiums, and bridges. These environments generally have complex ventilation conditions and large air volumes. The smoke generated by the smoke temperature detector is quickly dispersed by the flowing air as soon as it is emitted, making it difficult to accumulate near the smoke temperature probe and form a stable concentration. Since the normal operation of the smoke temperature probe is based on the fact that it will only trigger an action after a certain smoke concentration is reached, the inability to maintain a stable concentration interferes with the normal test judgment, requiring repeated testing. It may even be necessary to wait until the wind is calm to conduct the test, making the originally simple test process lengthy and complicated. Therefore, it is necessary to design a practical and windproof device for smoke temperature probe testing. Utility Model Content
[0005] The purpose of this invention is to provide a device for testing smoke temperature probes, so as to solve the problems mentioned in the background art.

One side of each of the two locking plates is fixedly connected to a windproof cover that cooperates with the smoke temperature detection nozzle.

One side of the U-shaped locking block is inserted into the interior of the locking opening.
[0008] According to the above technical solution, a washer is fixedly connected to the lower end of the connecting rod, and a threaded groove is opened on the lower side of the connecting rod.
[0009] According to the above technical solution, a fitting pad is fixedly connected to the upper side of the windproof cover.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-5 The present invention provides a technical solution: a device for testing smoke temperature probe, including a connecting rod 1, an e-liquid cylinder 2 fixedly connected to the upper side of the connecting rod 1, a smoke temperature detection nozzle 3 set on the upper side of the e-liquid cylinder 2, the smoke temperature detection nozzle 3 having atomization principle, heating principle and pressure driving principle, which is a common existing technology on the market, a support ring 4 fixedly connected to the connecting rod 1, a compression spring 5 fixedly connected to the upper side of the support ring 4, a pressure block 6 that slides with the connecting rod 1 fixedly connected to the upper end of the compression spring 5, and hollow blocks 7 fixedly connected to both sides of the pressure block 6; Locking plates 8 are slidably fitted on adjacent sides of the two hollow blocks 7. Locking ports 9 are opened on adjacent sides of the two locking plates 8. A windproof cover 10 that cooperates with the smoke temperature detection nozzle 3 is fixedly connected to one side of the two locking plates 8. The windproof cover 10 is made of common high-definition transparent plastic material with a thickness of about 2mm. It is open at the top and bottom, and the smoke temperature detection nozzle 3 can be observed through its lower side without causing any interference. A quick-release mechanism 11 that cooperates with the locking port 9 is provided on the two hollow blocks 7. The quick-release mechanism 11 includes a movable port 111 opened on the upper side of the two hollow blocks 7, a U-shaped locking block 112 that is slidably fitted on the inner wall of the two movable ports 111, and a locking spring 113 that is fixedly connected between the U-shaped locking block 112 and the movable port 111. One side of the U-shaped locking block 112 is inserted into the inside of the locking port 9.
[0017] Please see Figure 1 and Figure 5 A washer 12 is fixedly connected to the lower end of the connecting rod 1. A threaded groove 13 is provided on the lower side of the connecting rod 1. The washer 12 fixed to the lower end of the connecting rod 1 can provide friction with other components after subsequent connection, while the threaded groove 13 on its lower side facilitates connection with other components.
[0018] Please see Figure 2 A bonding pad 14 is fixedly connected to the upper side of the wind shield 10. When the wind shield 10 comes into contact with the top of the object to be tested, the bonding pad 14 will come into contact with the corresponding top. On the one hand, it can better fill the gap between the wind shield 10 and the object, enhance the windproof effect, and ensure that the blown smoke or heat is not easily affected by the outside wind. On the other hand, it can also play a certain role in protecting the surface of the object in contact, avoiding scratches and other damage to the object during operation.
[0019] Please see Figure 2 and Figure 5 The e-liquid cartridge 2 has an injection port 15 on one side. The inner wall of the injection port 15 is threaded with a sealing bolt 16. When it is necessary to add e-liquid to the e-liquid cartridge 2 to generate smoke, the sealing bolt 16 can be unscrewed to open the injection port 15, so that the e-liquid can be injected into the cartridge. After the injection is completed, the sealing bolt 16 is screwed into the injection port 15. The tight thread fit forms a seal to prevent e-liquid leakage and prevent external impurities from entering the e-liquid cartridge 2. This ensures that the e-liquid cartridge 2 can store e-liquid normally and provides the material basis for the subsequent blowing of smoke through the smoke temperature detection nozzle 3.
[0020] Please see Figure 2A laser sensor 17 is fixedly connected to the upper side of the smoke temperature detection nozzle 3. The laser sensor 17 and the smoke temperature detection nozzle 3 are electrically connected. When using this smoke temperature probe testing device, the laser sensor 17 can sense and monitor the distance between itself and the smoke temperature probe being tested. When it senses that the distance to the target has reached the preset appropriate conditions, it will transmit the corresponding electrical signal to the smoke temperature detection nozzle 3, triggering the smoke temperature detection nozzle 3 to start and accurately blow out hot air or smoke to test the smoke temperature probe, avoiding spraying and wasting internal liquid during non-detection processes.
[0021] Please see Figure 4 A limiting block 18 is fixedly connected to the locking plate 8. The limiting block 18 fits against the hollow block 7. When the locking plate 8 is inserted into the hollow block 7, the limiting block 18 fits against one side of the hollow block 7. After fitting, the locking opening 9 and the U-shaped locking block 112 coincide.
[0022] The implementation principle of this application is as follows: When the smoke temperature probe testing device is in use, the smoke oil cylinder 2 is used to store substances such as smoke oil that generate smoke, and the smoke temperature probe can blow out hot air or smoke through the smoke temperature probe nozzle 3 to test the smoke temperature probe. When the wind shield 10 is needed to resist the interference of external wind, first determine the wind direction. By aligning the wind shield 10 with the wind direction, push the two locking plates 8 towards each other to move the wind shield 10 to the appropriate position. At this time, the locking port 9 on the locking plate 8 will correspond to the quick release mechanism 11 on the hollow block 7. The U-shaped locking block 112 in the quick release mechanism 11 is inserted into the locking port 9 under the action of the locking spring 113, thereby fixing the wind shield 10. During use, the wind shield 10 first contacts the top of the detection component and then continues to face upward. The compressed spring 5 contracts, so that the output end of the smoke temperature detection nozzle 3 is in contact with the probe to spray hot air or smoke. The wind shield 10 can effectively block the influence of external wind on the blown smoke or hot air, which helps to maintain a stable smoke concentration and ensures that the smoke temperature probe can be tested in a qualified environment, improving the accuracy and reliability of the test and avoiding problems such as repeated testing and extended test process due to wind interference. When the windproof cover 10 needs to be removed, the elastic force of the locking spring 113 is overcome, and the U-shaped locking block 112 is pushed from the locking port 9 in a similar direction to separate it from the locking port 9 and release the restriction. Then the locking plate 8 can be pushed to remove the windproof cover 10 from the working position, so that it will not cause any impact during indoor use. The laser sensor 17 on the smoke temperature detection nozzle 3 can be electrically coupled with the smoke temperature detection nozzle 3. When the laser sensor 17 is close to the top object, it controls the smoke temperature detection nozzle 3 to spray air. E-liquid can be injected into the e-liquid cylinder 2 through the injection port 15. After injection, it is sealed with the sealing bolt 16. The gasket 12 at the lower end of the connecting rod 1 can provide friction between it and the outer pipe fitting. The threaded groove 13 on its lower side facilitates connection with other components. The fitting pad 14 on the windproof cover 10 facilitates the protection of the wall surface.
