For example, Chinese Patent Publication No. CN216204466U discloses a circulating air source heat pump in the field of air source heat pump technology. It includes an air source heat pump body and a snap-fit structure. The snap-fit structure includes a ventilation pipe and an upper connecting pipe. The ventilation pipe is fixedly connected to the upper surface of the air source heat pump body. Multiple second snap-fit pieces are fixedly connected to the outer surface of the ventilation pipe. Each second snap-fit piece has a through groove. A connecting sleeve is fixedly connected to the second snap-fit piece at the position corresponding to the through groove. A movable rod is slidably connected inside the connecting sleeve. A push plate is fixedly connected to the end of the movable rod near the connecting sleeve.

The end of the second compression spring away from the push plate is fixedly connected to the connecting sleeve. A dustproof screen that is easy to install and remove is provided for easy cleaning by the user.
[0003] The existing technology described above uses a detachable structure for the dustproof net on the top of the air source heat pump, which facilitates the removal and cleaning of the dustproof net.
