It uses ion smoke sensor inside and is widely used in various fire alarm systems. In order to ensure the normal use of the internal components of the smoke alarm, the smoke sensor needs to be tested for smoke regularly.

[0003] In the existing smoke test on the smoke sensor, since the smoke sensor is generally installed at a high place, the temperature of the smoke is low when it reaches the installation position, and the high temperature resistance performance of the smoke sensor cannot be tested well. It has high limitations, and when the test rod is held manually, the smoke nozzle can only be tested by rotating the entire test rod, and the pitch angle of the smoke nozzle cannot be adjusted. It cannot adapt to the use of smoke sensor tests in different installation positions and directions, has poor flexibility and adaptability, and is not practical. Utility Model Content

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0024] As attached Figure 1 To Attachment Figure 5 As shown:

[0025] Embodiment 1: The utility model provides a high temperature resistance testing device for smoke sensing components, including a holding component 1, the holding component 1 includes a gripping handle 101, an operating column 102 and an extension column 103, the bottom of the operating column 102 is rotatably connected to the inside of the gripping handle 101, and the extension column 103 is fixedly installed on the top of the operating column 102; an adjusting component 2, the adjusting component 2 includes a control seat 201 and a linkage rod 202, the control seat 201 is plugged into the inside of the operating column 102, and the rod body of the linkage rod 202 is rotatably connected to the inside of the operating column 102 and the extension column 103; a testing component 3, the testing component 3 includes a smoke guide tube 301, the smoke guide tube 301 is connected to the top of the extension column 103, and the smoke guide tube 301 is connected to the smoke generator through a hose.

[0026] In the disclosed embodiment, the test component 3 also includes a heating seat 302, which is fixedly mounted inside the smoke guide tube 301, and a heating wire is provided inside the heating seat 302. During use, the test component 3 can guide the smoke emitted by the smoke generator so as to spray it toward the smoke sensor to be tested for testing. During use, the tester can hold the grip 101 and extend the test component 3 to the smoke sensor position for use. The operation is convenient and flexible, and the smoke can be heated by the heating seat 302 when it is sprayed out from the smoke guide tube 301. The heated smoke can also test the high temperature resistance of the smoke sensor. The function is powerful and the use is flexible.

[0027] In the disclosed embodiment, a linkage gear 2021 is provided on the top of the linkage rod 202, and a pitch gear 3011 is provided on the side of the rotating shaft of the smoke guide tube 301. The pitch gear 3011 and the linkage gear 2021 are meshed and transmitted. In use, the regulating component 2 can realize the positioning of the use angle of the smoke guide tube 301. When the control seat 201 is directly rotated, the control seat 201 can drive the operating column 102 to rotate synchronously. When the operating column 102 rotates, it can drive the test component 3 to rotate synchronously and coaxially with the operating column 102 through the extension column 103 at its top, thereby changing the use angle of the smoke guide tube 301. At the same time, the regulating component 2 can also adjust the pitch angle of the smoke guide tube 301. When it is necessary to adjust the smoke guide tube 3 01, it is only necessary to move the control seat 201 up and down. A linkage protrusion 2011 is provided inside the control seat 201, and a spiral linkage groove 2022 is provided inside the linkage rod 202. The linkage protrusion 2011 is inserted into the linkage groove 2022. When the control seat 201 moves up and down, the linkage protrusion 2011 can drive the linkage rod 202 to rotate independently of the lifting component 1 through the linkage groove 2022. Therefore, when the linkage rod 202 rotates alone, the linkage gear 2021 can drive the smoke guide tube 301 to rotate and adjust in the pitch direction through the pitch gear 3011, thereby adjusting the pitch angle of the smoke guide tube 301. It can adapt to the test of smoke sensors and internal components in different installation positions and directions, and has strong adaptability.

[0028] In the disclosed embodiment, a reset spring 1021 is provided on the side of the operating column 102, and the two ends of the reset spring 1021 are respectively fixedly installed on the outside of the operating column 102 and the outside of the control seat 201. There are two reset springs 1021, and the two reset springs 1021 are symmetrically arranged on both sides of the control seat 201. During use, the two reset springs 1021 can automatically be in the middle position of the operating column 102 when the control seat 201 is not pushed or pulled by external force, thereby automatically putting the test component 3 in a reset state, which is convenient for regulation and use.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In the present invention, the tester can use the test component 3 by holding the gripping handle 101 and extending it to the smoke sensing position. The test component 3 can guide the smoke emitted by the smoke generator so as to spray it toward the smoke sensing device to be tested. The smoke can be heated by the heating seat 302 when it is sprayed out from the smoke guide tube 301. The heated smoke can also test the high temperature resistance of the smoke sensing device. When it is necessary to adjust various angle parameters of the smoke guide tube 301, the corresponding operation can be achieved through the control seat 201. The regulating component 2 can position the use angle of the smoke guide tube 301. When the control seat 201 is directly rotated, the control seat 201 can drive the operating column 102 to rotate synchronously. When the operating column 102 rotates, it can drive the test component 2 through the extension column 103 at its top. Component 3 rotates synchronously and coaxially with the operating column 102, thereby changing the use angle of the smoke guide tube 301. At the same time, the control component 2 can also adjust the pitch angle of the smoke guide tube 301. When the pitch angle of the smoke guide tube 301 needs to be adjusted, it is only necessary to move the control seat 201 up and down. When the control seat 201 moves up and down, the linkage protrusion 2011 can drive the linkage rod 202 to rotate independently of the lifting component 1 through the linkage groove 2022. Therefore, when the linkage rod 202 rotates alone, the linkage gear 2021 can drive the smoke guide tube 301 to rotate and adjust in the pitch direction through the pitch gear 3011, thereby adjusting the pitch angle of the smoke guide tube 301, which can adapt to the testing of smoke sensors and their internal components in different installation positions and orientations.

[0031] In another embodiment, the length of the extension column 103 can be set according to actual needs, so as to adapt to the testing of smoke detectors at different installation heights, further improving the flexibility of the device.
