Specific embodiments
[0023] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a hot smoke generating device detector, which includes a base 1. Both sides of the top of the base 1 are fixedly connected with support seats 2. A fixed seat 3 is fixedly connected between the tops of the two support seats 2. Both sides of the top of the fixed seat 3 are fixedly connected with support plates 4. A top plate 5 is fixedly connected between the tops of the two support plates 4. A lifting assembly 6 penetrates between the bottom of the top plate 5 and the top of the fixed seat 3. The top of the lifting assembly 6 is fixedly connected with a smoke generating assembly 7. The top of the smoke generating assembly 7 is communicated with a protective cover 8. Four sides of the bottom of the base 1 are all fixedly connected with universal wheels 9. The four universal wheels 9 can assist the whole device to move. The protective cover 8 is in the shape of an inverted frustum and has an open top. When the protective cover 8 covers the smoke detector installed on the top of the room through the top opening, the smoke generated inside the smoke generating assembly 7 can be concentrated and transported to the smoke detector for detection.
[0025] Please refer to Figures 1-2 , the lifting assembly 6 includes a lead screw 61 and a threaded sleeve 63. The lead screw 61 is rotatably connected to the top of the fixed seat 3. The threaded sleeve 63 penetrates between the top and the bottom of the top plate 5. The top end of the lead screw 61 penetrates the bottom end of the threaded sleeve 63 and extends into the interior of the threaded sleeve 63. The top end of the threaded sleeve 63 is fixedly connected with a connecting plate 62. The bottom of the smoke generating assembly 7 is fixedly connected with the top of the connecting plate 62. Both sides of the bottom of the connecting plate 62 are fixedly connected with limiting rods 64. The bottom ends of the two limiting rods 64 penetrate the top of the top plate 5 and extend above the bottom end of the threaded sleeve 63. The bottom ends of the two limiting rods 64 are both fixedly connected with limiting blocks 65. The bottom end of the lead screw 61 penetrates the fixed seat 3 and extends below the fixed seat 3. The bottom end of the lead screw 61 is fixedly connected with a turntable 66. One side of the bottom of the turntable 66 is fixedly connected with a handle, which is convenient for quickly rotating the turntable 66. Both limiting rods 64 are in contact with the top plate 5. The threaded sleeve 63 is in contact with the top plate 5. The threaded sleeve 63 is threadedly connected with the lead screw 61. The limiting rods 64 have a limiting effect on the connecting plate 62. The limiting blocks 65 have a limiting effect on the limiting rods 64 and limit the upward movement distance of the threaded sleeve 63 to prevent the threaded sleeve 63 from disconnecting from the lead screw 61. When the lead screw 61 rotates forward and backward, the connecting plate 62 can be pushed up and down through the threaded sleeve 63.
[0026] Please refer to Figures 2-5The smoke generating assembly 7 comprises a fixing box 71, which is fixedly connected to the top of the connecting plate 62 in the lifting assembly 6, and the top of the fixing box 71 is connected to the bottom of the protective cover 8. A smoke baffle 72 runs through one side of the fixing box 71, and one side of the smoke baffle 72 extends to one side of the inner wall of the fixing box 71. A combustion box 73 is embedded on the other side of the fixing box 71 and below the smoke baffle 72. A handle 74 is fixedly connected to one side of the combustion box 73, and a mounting shaft 75 is fixedly connected to the other side of the fixing box 71 and just above the handle 74. The axial surface of the mounting shaft 75 is provided with a connecting sleeve 76 through a self-locking rotating shaft rotation sleeve, and a clamping block 77 is fixedly connected to the bottom of the connecting sleeve 76. A rubber block 78 is fixedly connected to one side of the clamping block 77 and located on one side of the combustion box 73. The front and back sides of the smoke baffle 72 are respectively embedded with the front and back sides of the inner wall of the fixing box 71. When the smoke baffle 72 is fully embedded in the fixing box 71, combustion inside the combustion box 73 can be prevented from burning. When the block 77 is rotated 180 degrees and moved to the side of the fixed box 71, it can be fixed by fitting the rubber block 78 to the side of the fixed box 71.
[0027] Specific implementation method: By rotating the block 77 inside the smoke generating assembly 7 by 180°, the block 77 is rotated on the axial surface of the mounting shaft 75 through the connecting sleeve 76, and the block 77 is removed from the connection between the top of the combustion box 73 and the fixed box 71. The combustion box 73 can be pulled out to the left from the inside of the fixed box 71 through the handle 74, and the ignitable material is placed in the combustion box 73. After the combustion box 73 is pushed to the right into the inside of the fixed box 71, the block 77 is rotated 180° and reset, and the combustion box 73 can be fixed in the fixed box 71. The smoke generated by the combustion material will gather under the smoke baffle 72 and will not overflow at will, thereby avoiding the phenomenon that the air quality of the fire passage is reduced due to smoke in the fire detection environment.
[0028] Push the whole device so that the top opening of the protective cover 8 is aligned with the lower part of the smoke detector. Manually rotate the turntable 66 inside the lifting component 6. When the turntable 66 rotates forward and backward, it can drive the lead screw 61 to rotate forward and backward, thereby driving the threaded sleeve 63 to push the connecting plate 62 to move up and down for adjustment. Then, the height of the smoke generating component 7 and the protective cover 8 can be adjusted. After the protective cover 8 covers the smoke detector installed on the top of the room through the top opening, stop rotating the turntable 66 and pull the smoke baffle 72 to the right, so as to open the channel between the fixed box 71 and the protective cover 8. Then, the smoke can be concentratedly conveyed to the smoke detector through the protective cover 8 for smoke alarm detection, reducing the amount of smoke generated during the fire detection process and avoiding the phenomenon of false triggering of smoke detectors in other positions.
[0029] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
