The end of the feed pipe 6 away from the dust tank 5 is fixedly connected to a shunt pipe 8 connected to the top inner side of the test box body 1. The dust can enter the test box body 1 evenly through the shunt pipe 8. A number of dust fans 9 with adjustable wind speeds are fixedly installed on the upper part of the right inner wall of the test box body 1. The dust fans 9 can be used for horizontal blowing. The dust transported by the shunt pipe 8 can simulate the impact and wear that the airflow in the horizontal dust blowing process may cause to the product surface, which is helpful to evaluate the durability and stability of the product during long-term use.
