Problems solved by technology

Most of the existing mufflers have a relatively high temperature of the airflow discharged from the exhaust port. Although some existing mufflers have designed some structural optimization measures inside, the actual cooling effect is not ideal. Those skilled in the art In order to obtain a better cooling effect, it is necessary to improve the current muffler structure

Abstract

The invention discloses a catalytic agent silencer capable of lowering the exhaust temperature, and belongs to the technical field of air flow silencers. The catalytic agent silencer solves the technical problem that an existing catalytic agent silencer is high in exhaust temperature. The catalytic agent silencer comprises a silencer body. The silencer body is provided with an exhaust passageway, an exhaust gas outlet and an exhaust port. A diversion cover is arranged outside the exhaust port and comprises a diversion wall and a flow blocking wall. Diversion holes are formed in the diversion wall. A semi-closed air flow buffer space is defined by the diversion wall and the flow blocking wall. The catalytic agent silencer serves as an air flow silencer of a machine or an engine or serves as an air flow silencer of an internal combustion engine, for example, a catalytic agent silencer applied to a gardening tool gasoline engine.

Description

【Technical field】 [0001] The invention relates to a catalyst muffler and belongs to the technical field of airflow mufflers. 【Background technique】 [0002] The existing domestic and foreign production of hand-held garden tools powered by gasoline engines, in order to meet the emission standards, a catalytic silencer is installed on the tool. Most of the existing mufflers have a relatively high temperature of the airflow discharged from the exhaust port. Although some existing mufflers have designed some structural optimization measures inside, the actual cooling effect is not ideal. Those skilled in the art In order to obtain a better cooling effect, it is necessary to improve the current muffler structure. 【Content of invention】 [0003] The problem to be solved by the present invention is to provide a catalytic silencer which can effectively reduce the exhaust gas temperature. [0004] In order to solve the problems of the technologies described above, the present inv...
