Description

Heat radiation structure of cleaning machine
Technical Field
The invention relates to the technical field of cleaning equipment, in particular to a heat dissipation structure of a cleaning machine.
Background
With the development of society, people's awareness of environmental protection is also increasing, and people's requirements are getting higher in the aspect of garbage collection. At present, dust collection equipment is mainly adopted, the working principle of the dust collection equipment is that an impeller rotates at a high speed, air negative pressure is generated in a sealed shell, and dirt such as dust, garbage and the like is sucked into the shell. Dirt is then separated from the air internally, the dirt is left in place while clean air is discharged out of the cleaner. When handling heavy garbage, such as some glass bottles, small dust suction devices often have insufficient suction, and therefore use the engine as power to cause the dust suction device to generate more suction.
The dust collection equipment adopts the engine as power and has the problem of loud engine noise, so that a silencer is often arranged on the engine to reduce the noise generated when the dust collection equipment is used. The engine generates a large amount of heat during operation, and heat dissipation treatment is required for the engine and a muffler connected to the engine. In the prior art, the heat dissipation treatment of the silencer is mainly to add a heat shield or a heat dissipation plate structure of the silencer.
