Technical Field

[0001] The utility model relates to the technical field of garden tools, in particular to an anti-collision and silencer device for a three-way catalytic converter. Background Art

[0002] Garden tools refer to various implements and equipment used specifically for landscaping, plant care, and landscape maintenance. These tools can be divided into multiple categories based on their purpose, function, and power source. Among garden tools, some fuel-powered equipment, such as fuel-powered lawn mowers and fuel-powered generators, require the installation of a three-way catalytic converter for exhaust purification to effectively clean exhaust gases and protect the environment.

[0003] For example, the Chinese patent application number CN206035590U (a novel three-way catalytic converter) includes an air intake grille, a heat-conducting column, an air outlet pipe, an air intake pipe, a fixing hole, a bearing, and a filler. The air intake grille is connected to a honeycomb porcelain, and a bearing is provided at its upper end. The bearing is provided with steel balls and an insulation layer on its side. The fixing shaft is connected to the fan blades. The primary filter is connected to the ionization plate, and a dust collecting plate is provided at the right end of the ionization plate. The right end of the composite filter is provided with a catalyst. The right end of the air outlet pipe is provided with a filter screen. The left end of the air intake pipe is provided with a fixing hole. The outer side of the buffer layer is provided with a protective shell and the interior is provided with a filler. This novel three-way catalytic converter is modified from the existing three-way catalytic converter for automobile exhaust treatment. We have set a movable honeycomb porcelain that can rotate with the exhaust gas, which can effectively avoid the problem of clogging over time and greatly increase the service life of the three-way catalytic converter.

[0004] However, the existing three-way catalytic converter lacks external protection and relies on its own shell to resist collision, which easily causes surface damage, has high replacement costs, is noisy, and has poor noise reduction effect; therefore, it does not meet existing needs. In this regard, we propose an anti-collision and noise reduction device for a three-way catalytic converter. Utility Model Content
