Description

Technical Field

[0001] The utility model relates to the technical field of ventilation pipeline adjustment, in particular to a heating and ventilation pipeline adjustment device. Background Art

[0002] A heating and ventilation pipe regulating device is an important regulating device, which can ensure the normal operation and high efficiency of the heating, ventilation and gas transmission systems, and plays a very important role in realizing the reliable operation and transmission efficiency of the system. Publication No. CN 220436707 U discloses a heating and ventilation pipe regulating device. By starting the motor 2, the rotating shaft at the bottom of the motor 2 drives the rotating rod 2 to rotate, and the rotating rod 2 drives the incomplete gear 1 to mesh with the rack, so that the rack slides to the left on the inner wall of the pipe, driving the reset spring fixedly connected to the left side of the slider to contract, and at the same time the rack meshes with the incomplete gear 2, the incomplete gear 2 drives the rotating rod 3 to rotate synchronously, and the rotating rod 3 drives the cam to rotate, so that the raised part of the cam contacts the filter, so that the filter slides downward on the outer wall of the slide rod, driving the spring to extend, and when the raised part of the cam no longer contacts the filter, under the action of the spring, the filter slides upward, thereby causing the filter to reciprocate up and down, preventing the filter from being blocked, achieving the effect of self-cleaning of the filter, and solving the problem that the filter cannot be self-cleaned.

[0003] When cleaning the filter, the above patent mainly "contacts the raised part of the cam with the filter, causing the filter to slide downward on the outer wall of the slide rod, driving the spring to extend, and when the raised part of the cam is no longer in contact with the filter, the filter slides upward under the action of the spring, thereby causing the filter to reciprocate up and down to prevent the filter from being blocked, thereby achieving a self-cleaning effect of the filter." However, this operation method will shake the dust on the filter into the pipe, and the dust will be blown into the environment during heating, causing environmental pollution. In addition, if the filter is removed for cleaning as in the prior art, the vibration, movement and other factors during the disassembly process will also cause the dust on the filter to fall off, thereby polluting the disassembly environment, causing accidental inhalation by the disassembler, and even flying into the disassembler's eyes, posing a safety hazard.
