[0026] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0027] Embodiment 1: As shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown: The present invention provides an automatic igniter for a purification and emission chimney, comprising a purification chimney 1, a telescopic component and a traction component;

[0028] A mounting seat 2 is fixed on the side of the purification chimney 1, and a fixing frame 3 is fixedly connected to the side of the mounting seat 2;

[0029] The telescopic assembly includes a cylinder 4, a support rod 5 and a mounting rod 7. The cylinder 4 is mounted on the inner wall of the fixing frame 3. The telescopic end of the cylinder 4 is connected to the support rod 5. The mounting rod 7 is fixed at the side wall of the support rod 5. An inclined rod 8 is fixed at one end of the mounting rod 7. A protective rod 10 is rotatably mounted at one end of the inclined rod 8. Both the protective rod 10 and the inclined rod 8 are made of stainless steel. A reset shaft 9 is connected between the ends of the protective rod 10 and the inclined rod 8. An igniter 11 is installed in the inner cavity of the protective rod 10. The support rod 5 is driven to telescope by controlling the cylinder 4, so that the igniter 11 is raised to the side around the top of the purification chimney 1. The ignition operation can be quickly realized by controlling the igniter 11 to work. By wrapping the igniter 11 with the protective rod 10, the influence of the high temperature of the flame burning at the chimney mouth on the igniter 11 can be effectively alleviated.

[0030] As attached Figure 4As shown: the traction assembly includes an electric push rod 15, a stretching plate 18, a pull rope 19, a guide frame 24 and a pull rope 19. The inner wall of the support rod 5 is provided with a control groove 14. The electric push rod 15 is installed on the inner bottom surface of the control groove 14. A connecting rod 16 is installed at the telescopic end of the electric push rod 15. One end of the connecting rod 16 is connected to the stretching plate 18. The pull rope 19 is connected between the stretching plate 18 and the protective rod 10. The guide frame 24 is fixed to the side wall of the inclined rod 8, and the pull rope 19 passes through the guide frame 24; the pull rope 19 is a metal rope; by setting the inclined rod 8, the protective rod 10 and the igniter 11 can be located away from the chimney mouth;

[0031] As attached Figure 6 As shown: when the igniter 11 is far away from the chimney opening and cannot be ignited, the electric push rod 15 is controlled to drive the connecting rod 16 to extend and retract, the connecting rod 16 pulls the stretching plate 18 to move, the stretching plate 18 drives the pull rope 19 to move, and the pull rope 19 can stably pull the protective rod 10 to rotate through the guide frame 24, so that the igniter 11 is close to the chimney opening, thereby achieving precise ignition.

[0032] A return spring 17 is connected to the top wall of the control groove 14, and the bottom end of the return spring 17 is connected to the stretching plate 18. The bottom surface of the stretching plate 18 is fixedly connected to a clamping frame 21. A micro cylinder 22 is installed at one end of the connecting rod 16. A pin rod 23 is connected to the telescopic end of the micro cylinder 22, and the pin rod 23 is engaged with the clamping frame 21. When the ignition is completed, since the igniter 11 is too close to the fire source, the flame at the chimney mouth will quickly burn to the vicinity of the igniter 11. After the ignition of the igniter 11 is completed, the micro cylinder 22 works quickly to move the pin rod 23. 3 is retracted, the pin rod 23 is separated from the card frame 21, and the limit of the card frame 21 is released. At this time, the reset spring 17 is quickly reset. After the protection rod 10 loses its pulling force, the reset shaft 9 is quickly reset, and the protection rod 10 rotates clockwise to restore the igniter 11 to a position away from the chimney. In this process, the rebound is rapid, thereby greatly protecting the igniter 11, so that the igniter 11 can be continuously used in subsequent work; after the ignition is completed, the igniter 11 can be quickly lowered to a safe position in cooperation with the work of the cylinder 4.

[0033] The top wall of the control groove 14 is fixedly connected to a limit rod 20, which is located in the reset spring 17, and the position of the limit rod 20 corresponds to the stretching plate 18. When the reset spring 17 is reset, the stretching plate 18 reaches the bottom end of the limit rod 20, and the limit rod 20 limits the stretching plate 18, ensuring that the micro cylinder 22 can stably cooperate with the card frame 21 to ensure the stability of the entire device.

[0034] A battery 13 and a control board 12 are also installed in the support rod 5, and the electric push rod 15, the micro cylinder 22, and the igniter 11 are all electrically connected to the control board 12;

[0035] The battery 13 is installed in the support rod 5 to provide the required power for the control board 12 and the electric push rod 15, the micro cylinder 22 and the igniter 11 connected thereto. As a power source, the battery provides a stable DC power supply for the entire system, ensuring that these components can work normally without external power supply access.

[0036] The control panel 12 sends a control signal to the electric push rod 15 through a preset program; when the position of the igniter 11 needs to be adjusted to make it closer to the chimney opening to achieve precise ignition, the control panel 12 will send a start signal to the electric push rod 15; after the electric push rod 15 receives the signal, the internal motor starts working, pushing its telescopic end to extend or retract, driving the connecting rod 16 to perform corresponding telescopic movement, thereby achieving the pulling or release of the tension plate 18, and driving the position adjustment of the protective rod 10 and the igniter 11 through the pull rope 19.

[0037] After ignition is completed, in order to protect the igniter 11, it needs to be quickly pulled back to the position away from the chimney. At this moment, the control panel 12 can send a signal to the miniature cylinder 22.

[0038] After receiving the signal, the telescopic end of the micro cylinder 22 will retract the pin 23, so that the pin 23 will be separated from the card frame 21, triggering the reset spring 17 to drive the stretching plate 18 to reset, thereby driving the protection rod 10 to rotate and pulling the igniter 11 back.

[0039] The control panel 12 can control the ignition operation of the igniter 11; when the cylinder 4 lifts the igniter 11 to a position near the chimney mouth and ignition is required, the control panel 12 sends a start signal to the igniter 11 to generate sparks or flames.

[0040] As attached Figure 5 As shown: two sets of guide wheels 25 are installed on the inner wall of the guide frame 24, and the pull rope 19 is located inside the two sets of guide wheels 25; by providing the guide wheels 25, the pull rope 19 can be effectively limited to ensure the stability of the pull rope 19 during use.

[0041] A positioning frame 6 is fixedly connected to the peripheral side of the support rod 5 , and an installation rod 7 is fixedly connected to the inner wall of the positioning frame 6 .

[0042] As can be seen from the above, when the purification and emission chimney needs to be ignited, the cylinder 4 is first controlled to extend and retract, and the telescopic end of the cylinder 4 drives the support rod 5 to perform telescopic movement, thereby raising the igniter 11 installed in the inner cavity of the protective rod 10 to the position around the top opening of the purification chimney 1.

[0043] The igniter 11 is controlled to start working, and the spark or flame generated by it is used to ignite the combustible gas in the chimney to achieve the ignition operation. In this process, the protective rod 10 will wrap the igniter 11. Since the protective rod 10 and the inclined rod 8 are made of stainless steel, the high temperature of the burning flame at the chimney mouth can effectively alleviate the influence of the igniter 11, and play a certain protective role.

[0044] In the initial state, the protection rod 10 and the igniter 11 are placed away from the chimney opening by setting the inclined rod 8, which may result in a poor ignition effect.

[0045] When this happens, by controlling the electric push rod 15 to work, the telescopic end of the electric push rod 15 drives the connecting rod 16 to telescope, and the connecting rod 16 pulls the stretching plate 18 to move.

[0046] The movement of the stretching plate 18 will drive the pull rope 19 to move in the guide frame 24. Because the pull rope 19 passes through the guide frame 24 and is a metal rope, it has certain strength and stability. Under the limiting and guiding action of the two sets of guide wheels 25 in the guide frame 24, the pull rope 19 can stably pull the protective rod 10 to rotate around the reset shaft 9, so that the igniter 11 is close to the chimney mouth, thereby achieving precise ignition.

[0047] After the igniter 11 completes the ignition, the flame at the chimney mouth will burn around the igniter 11 due to the close distance. At this time, the micro cylinder 22 works quickly to retract the pin rod 23 at its telescopic end, so that the pin rod 23 is separated from the card frame 21, thereby releasing the limit on the card frame 21.

[0048] At this time, the reset spring 17 quickly resets under the action of its own elastic potential energy, the tension plate 18 moves upward under the drive of the reset spring 17, the protective rod 10 loses the tension of the pull rope 19, and rotates clockwise under the action of the reset shaft 9, so that the igniter 11 returns to a position away from the chimney mouth, thereby achieving the purpose of protecting the igniter 11.

[0049] During this process, the limit rod 20 on the top wall of the control groove 14 will limit the stretching plate 18. When the reset spring 17 is reset, the stretching plate 18 reaches the bottom end of the limit rod 20, ensuring that the micro cylinder 22 can stably cooperate with the card frame 21 to ensure the stability of the entire device.

[0050] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a side frame 26 is fixed to the side wall of the fixing frame 3, and an automatic wire reel 27 is installed on the inner wall of the side frame 26.

[0051] As can be seen from the above, the automatic reel 27 organizes and stores the cables of the device to ensure that the cables can stably follow the rise during the extension and retraction of the cylinder 4, and the routing of the igniter 11 is carried out through the inside of the protective rod 10, avoiding the wire protection outside and improving the safety of the equipment.
