When the air blower works for a long time, the temperature of the cooling water rises, and the bimetallic strip of the outer wall of the relay pipe is bent due to high temperature, so that the cooling water flowing through is sprayed to the outside. With the air outlet hole of the air cooling pipe and the blade of the output end of the driving motor, the cooling water is scattered and blown to the outer wall of the fan by the airflow blown by the fan. The heat generated by the fan is absorbed and dissipated from the outside.

The use of cooling water is greatly reduced, and the spraying of cooling water also avoids affecting the cleanliness of the external environment, improving the safety of the air blower.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0027] The utility model provides a centrifugal blower with cooling mechanism, like Figures 1-5 The centrifugal blower with cooling mechanism includes the casing 1, the inside fixedly connected with the fan body 2 of casing 1, the lateral wall of fan body 2 is provided with cooling assembly,

[0028] Cooling assembly includes the fixed connection of water storage tank 3 in the lateral wall of fan body 2, the inside fixedly connected with water pump 4 of water storage tank 3, the output of water pump 4 is fixedly sleeved with water outlet pipe 5, the end of water outlet pipe 5 is fixedly sleeved with relay pipe 6, the upper top end of relay pipe 6 is fixedly connected with multiple bimetallic strips 7, the upper top end of water storage tank 3 is fixedly connected with drive motor 8 on the one side of relay pipe 6, the output of drive motor 8 is fixedly sleeved with the blade 9 for breaking up water flow.

[0032] Specifically, the shell 1 can provide sufficient external protection for the fan body 2, avoid external bumps to damage the fan body 2, and set the cooling assembly on the side wall of the fan body 2 to dissipate the heat generated by the fan body 2 during operation, avoid heat accumulation to cause the fan body 2 to overheat, and the water pump 4 extracts the cooling water in the water tank 3, and then enters the relay pipe 6 from the water outlet pipe 5, and then passes through the waterway pipe 14, and then enters the circulating pipe 13 on the side wall of the cooling tank 12, and then enters the other end of the cooling tank 12 through the circulating pipe 13, and then flows back to the inside of the water tank 3 through the waterway pipe 14, and the water body forms a circulation, and the circulating pipe 13 is used to dissipate heat from the fan body 2, and when the fan body 2 is used for a long time, the temperature reaches a certain degree, the temperature of the cooling water will rise, and the high-temperature cooling water will cause the bimetallic strip 7 on the top end of the relay pipe 6 to bend, and then the cooling water will flow out from the bent part of the bimetallic strip 7. Since the shell 1 is provided with the air cooling pipe 10, and the air outlet hole 11 of the air cooling pipe 10 is located on one side of the bimetallic strip 7, the airflow blown out by the air blower will drive the cooling water to impact the fan body 2, and the driving motor 8 on the top end of the water tank 3 is operated, and the high-speed rotating blades 9 at the output end are used to scatter the blown cooling water into particles, increase the contact area of the cooling water with the fan body 2, and dissipate the heat of the fan body 2 from the outside.
