In this embodiment, the air door panel body 1-1 is a circular plate, and the center of the circle coincides with the center of the through hole 1-2; the central axis of the air door panel body 1-1 is superposed with the central axis of the injection pipe 2-1.

As the air door plate 1 moves along the length direction of the nozzle 3 (namely moves towards the direction close to or far away from the injection pipe), the length of the fins 1-3 entering the injection pipe 2-1 is changed, the contact area of the fins 1-3 and the inner peripheral wall of the injection pipe 2-1 is changed, the shielding area of the inner peripheral wall of the injection pipe 2-1 to the primary air inlet 1-7 is changed, the area of a primary air introducing passage is changed, and the primary introduced air quantity of the injection pipe 2-1 is changed.

When the air door plate 1 moves towards the direction close to the injection pipe along the length direction of the nozzle 3, the length of the fins 1-3 entering the injection pipe 2-1 is increased, the contact area of the fins 1-3 and the inner peripheral wall of the injection pipe 2-1 is increased, the shielding area of the inner peripheral wall of the injection pipe 2-1 on the primary air inlet 1-7 is increased, the area of a primary air introducing channel is reduced, and the primary air introducing amount of the injection pipe 2-1 is reduced.

In the embodiment, the driving structure comprises a motor and a gear, the motor is connected with a central shaft of the gear, the gear is meshed with teeth on the outer peripheral surface of the air door plate body, and a through hole of the air door plate body is in threaded connection with the nozzle; the controller is connected with the motor, and control motor rotates, and the motor drives the gear and rotates, and the gear drives the wind door plant body and rotates, and the wind door plant is rotatory to be fed, moves to the direction that is close to or keeps away from to drawing the penetrating pipe along the nozzle. As another preferred design scheme of this embodiment, the driving structure includes an electric push rod, the electric push rod is fixed to the air door panel body, and the through hole of the air door panel body is slidably connected to the nozzle; the controller controls the electric push rod to stretch out and draw back, and the electric push rod drives the air door plate body to move towards the direction close to or far away from the injection pipe along the nozzle.

The controller receives the oxygen content sent by the sensor, when the oxygen content in the injection pipe is smaller than a set low threshold value, the controller sends a control signal to the driving structure, and the driving structure drives the air door plate to move along the nozzle in the direction far away from the injection pipe so as to increase the primary air introduction amount of the injection pipe 2-1; when the oxygen content is larger than a set high threshold value, the controller sends a control signal to the driving structure, and the driving structure drives the air door plate to move towards the direction close to the injection pipe along the nozzle so as to reduce the primary air introduction amount of the injection pipe 2-1.

In order to remind the user, the air door structure further comprises a voice alarm, and the voice alarm is connected with the controller. When the oxygen content in the injection pipe is smaller than a set low threshold value or larger than a set high threshold value, the controller sends a control signal to the voice alarm, and the voice alarm is controlled to send an alarm prompt to remind a user. Moreover, by designing the voice alarm, when the alarm is given continuously for multiple times, a user can manually rotate the air door plate or report the repair after obtaining the alarm prompt.

In this embodiment, the damper structure further includes a wireless communication module, the wireless communication module is connected to the controller, and the controller sends a signal to the outside through the wireless communication module. When the oxygen content is smaller than the set low threshold or larger than the set high threshold, the controller sends an alarm prompt signal to the mobile terminal through the wireless communication module so as to prompt a user in time.

An annular sealing boss 1-4 is formed on the periphery of the fin 1-3 on the air door plate body 1-1; when all the fins 1-3 completely extend into the injection pipe 2-1, the annular sealing boss 1-4 abuts against the air inlet end face 2-3 of the injection pipe 2-1, and the annular sealing boss 1-4 is tightly attached to the air inlet end face 2-3 to prevent the injection pipe 2-1 from air leakage.

When the air door panel 1 moves towards the direction far away from the injection pipe 2-1, and the fins 1-3 are just completely separated from the injection pipe 2-1, the primary air inlets 1-7 formed by the adjacent fins are completely exposed (as shown in fig. 3, the fins of the air door panel below the air door panel in fig. 3 are just separated from the injection pipe, and the fins of the air door panel above the air door panel in fig. 3 partially extend into the injection pipe), and the total area of the primary air inlets is maximum. Of course, if the air door plate is far away from the ejector pipe, the area can be infinite, but the area has no practical significance.

When the air door panel 1 moves towards the direction close to the injection pipe 2-1, and the fins 1-3 completely enter the injection pipe 2-1, the primary air inlets 1-7 formed by the adjacent fins are completely shielded (as shown in fig. 2, the fins of the air door panel at the lower part in fig. 2 completely enter the injection pipe, and the fins of the air door panel at the upper part in fig. 2 partially extend into the injection pipe), and the total area of the primary air inlets is minimum and is 0.

In order to facilitate the rotation of the air door panel 1, knob threads 1-5 are formed on the outer circumferential surface of the air door panel body 1-1. When the primary air quantity entering the injection pipe 2-1 needs to be adjusted, the air door plate 1 is rotated through the knob threads 1-5, so that time and labor are saved.

The central axis of the injection pipe 2-1 is superposed with the central axis of the air door panel body 1-1; the fins 1-3 are equal in size and shape, and the fins 1-3 are circumferentially arranged around the central axis of the air door plate body 1-1 at equal intervals, so that primary air entering the air inlet 2-2 of the injection pipe 2-1 is uniformly distributed in the circumferential direction, and the mixing uniformity of fuel gas and the primary air in the injection pipe 2-1 is improved.

The bottom edge of the fin 1-3 is flush with the table surface of the annular sealing boss 1-4. Namely, the height of the bottom edge of the fin 1-3 is equal to that of the annular sealing boss 1-4, and when the fin 1-3 just extends into the ejector tube completely, the annular sealing boss 1-4 is just abutted against the end face 2-3 of the air inlet. The maximum value of the total area of the primary air inlets formed by the adjacent fins is the circumference x (the distance between the annular sealing boss and the end face of the air inlet of the injection pipe) of the air inlet of the injection pipe/2. The fins are designed into a triangle, so that a primary air inlet is formed between the adjacent fins conveniently, the adjusting range of the air door plate is increased, and the adjusting range of the air door plate is doubled on the premise of the same primary air inlet area and the same injection pipe inlet area. And the appropriate primary air inlet area can be accurately determined.
