[0024] refer to Figure 5 A connecting plate 6 is fixedly connected to the back of the outer casing 51, and the front of the connecting plate 6 is fixedly connected to the back of the protective net 54.

[0025] As a technical optimization of this utility model, the connection plate 6 can reinforce the protective net 54, strengthen the connection between the protective net 54 and the outer shell 51, and enable the two to be connected more stably, thus preventing the protective net 54 from falling off.

[0026] refer to Figure 4 An auxiliary pull rod 7 is fixedly connected to the front of the cleaning groove 53, and the auxiliary pull rod 7 is used in conjunction with the cleaning groove 53.

[0027] As a technical optimization of this utility model, the auxiliary pull rod 7 can assist the cleaning groove 53, making it easier for the user to move the cleaning groove 53 and providing convenience for the user.

When the transmission screw block 43 moves, the transmission gear 47 on the surface of the rotating rod 45 meshes with the transmission tooth plate 48 fixed on the front of the body 1, forcing the rotating rod 45 to rotate while sliding. The cleaning component 49 (such as a brush or scraper) fixed on the surface of the rotating rod 45 rotates with the rotating rod 45 and rotates to clean the surface of the heat dissipation mesh 2. The fan component 52 in the recycling mechanism 5 starts and generates negative pressure airflow, which sucks the dust that has been cleaned off into the inner cavity of the outer shell 51 through the protective net 54, preventing the dust from spreading into the environment.

[0033] In summary, this air-cooled screw heat pump unit, by incorporating a cleaning mechanism, addresses the issue of dust accumulation in the airflow areas during long-term use, which reduces its cooling efficiency and ensures normal operation unaffected by external factors.
