[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] Combined with Figure 1 In order to solve the above technical problems, the technical solution provided by the utility model is: a smoke exhaust valve actuator, including a base 1, a control panel 2 is connected inside the base 1, and an adjustment button 20 is connected to the control panel 2. The base 1 is connected to the outside on the side close to the inlet and outlet 17 to facilitate the installation of the device on the wall.

[0024] The device is embedded in the wall through the base 1. The control panel 2 serves as a smoke exhaust valve actuator, that is, an adjustment switch panel. The base 1 is hollow to provide a storage space for the control panel 2.

[0025] Embodiment 2

[0026] Combined with Figure 1-5 The base 1 is rotatably connected to one end away from the control panel 2 and is provided with a transmission shaft 5. A driving motor 4 is connected inwardly on one side of the base 1 and cooperates with the transmission shaft 5 to provide power for the rotation of the transmission shaft 5. A bottom plate 3 that cooperates with the control panel 2 is connected inside the base 1. A support 6 is connected inside the base 1. A plurality of telescopic rods 11 are rotatably connected between the base 1 and the support 6. A plurality of support blocks 10 that cooperate with the telescopic rods 11 are connected on the bottom plate 3 and the support 6 to facilitate the movement of the telescopic rods 11 between the support 6 and the bottom plate 3. A threaded shaft 8 is connected to one side of the base 1 away from the control panel 2. A screw sleeve 7 that cooperates with the threaded shaft 8 is rotatably connected in the support 6. A gear transmission mechanism 9 is commonly connected between the screw sleeve 7 and the transmission shaft 5. One side of the base 1 is connected to The inlet and outlet 17, the base 1 is provided with baffles 16 on both sides of the inlet and outlet 17, the top of the base 1 is rotatably connected with a support shaft 12, a worm gear transmission mechanism 13 is commonly connected between the support shaft 12 and the transmission shaft 5, threaded ends 14 are connected at both ends of the support shaft 12, and the threaded ends 14 at both ends of the support shaft 12 are arranged in opposite directions, and a driving frame 15 with an internal thread structure at one end is connected at both ends of the support shaft 12, and the driving frame 15 is connected to the top of the baffle 16 at one end away from the support shaft 12, a support shaft 2 21 is connected to the bottom of the base 1, a support frame 18 is commonly connected between the support shaft 21 and the baffle 16, and one end of the support frame 18 is slidably connected to the support shaft 21, and through the above structure, an auxiliary support effect is provided for the baffle 16.

[0027] Through the rotation of the transmission shaft 5, under the action of the gear transmission mechanism 9 and the worm gear transmission mechanism 13, the following two effects are respectively achieved simultaneously. First, through the gear transmission mechanism 9, the screw sleeve 7 on the support 6 rotates, and under the limiting conditions provided by each telescopic rod 11 between the support 6 and the base plate 3, the threaded shaft 8 moves in the base 1, and one end is against the base plate 3 to telescope inside and outside the base 1, and each telescopic frame provides auxiliary support for it. Second, through the rotation of the support shaft 12 of the worm gear transmission mechanism 13, the baffles 16 on both sides of the inlet and outlet 17 move closer to or away from each other under the threaded cooperation with the driving frame 15, thereby opening or closing the inlet and outlet 17 of the base 1, and one side of the baffle 16 is close to the base 1, which can provide limiting conditions for the driving frame 15 to move on the support shaft 12. The lower support shaft 21 and the support frame 18 cooperate with each other, which can also provide limiting conditions for it and assist in supporting the baffle 16.
