Electric hammer dust blower

Abstract

The invention provides an electric hammer dust blower which comprises a dust blowing device and a telescopic rod. The dust blowing device is fixed on the telescopic rod. A mounting seat for fixing the telescopic rod on an electric hammer is disposed on the telescopic rod. A drill bit hole allowing the drill bit of the electric hammer to pass is formed in the dust blowing device. A fan generating air flows, a dust collecting chamber and a filter for filtering the air flows are arranged inside the dust blowing device. The air flows generated by the fan sequentially pass the drill bit hole, the dust collecting chamber and the filter and returns to the position of the fan after being filtered by the filter. The electric hammer dust blower has the advantages that the dust generated during operation of the electric hammer is blown to the dust collecting chamber by the air flows generated by the fan so as to achieve dust collecting, and dust collecting is achieved through dust blowing; the filter is disposed in the downwind direction of the air flows, the fan is disposed in the upwind direction of the air flows, so that the electric hammer dust blower is low in airtightness requirements of air ducts allowing the air flows to pass and also low in the manufacturing process requirements and manufacturing cost.

Description

technical field [0001] The invention relates to an electric hammer protection device, in particular to an electric hammer dust blower. Background technique [0002] The electric hammer is mainly used to drill holes in concrete, floors, brick walls, stones and other objects. The electric hammer will generate a lot of dust during the working process, which will easily pollute the surrounding environment and cause physical injury to the staff. In order to reduce the pollution of dust to the environment and the harm to the human body, an electric hammer vacuum cleaner is generally installed on the electric hammer. When the commonly used electric hammer vacuum cleaner is used, the flow direction of the air is from the drill bit through the air duct to the dust collection room, then from the dust collection room through the filter to the fan that generates the airflow, and finally through the motor and then discharged. Since the fans that generate the airflow and the filters tha...

Problems solved by technology

In this way, the manufacture of the electric hammer vacuum cleaner will have higher requirements and higher manufacturing costs.

In addition, if the filtering effect of the filter is not good, there will still be a small amount of dust discharged from the electric hammer vacuum cleaner to cause pollution
