Abstract

Disclosed is a suction tool for an electric vacuum cleaner provided with: a suction tool main body which comprises an opening (12a) in a lower surface, and comprises a suction chamber (12) thereinside that communicates with the opening (12a); and a connection pipe (18) which is attached to the suction tool main body and communicates with the suction chamber (12). An air intake port (35) for taking in external air is provided in the external surface of the suction tool main body, and an air exhaust port (38) for providing communication between the air intake port (35) and the suction chamber (12) is provided inside the suction tool main body. A sound absorption chamber is provided adjacent to but separately from a communication passage (39) for providing communicating between the air intake port (35) and the air exhaust port (38) of the suction tool main body.

Description

Technical field [0001] The invention relates to a suction member for an electric vacuum cleaner and an electric vacuum cleaner having the suction member for an electric vacuum cleaner. Background technique [0002] With regard to electric vacuum cleaners, research has been conducted to reduce the wind noise of suction air sucked in from an external air inlet provided in the front portion of the suction tool body. [0003] For example, a structure is proposed in which a suction chamber provided in the suction part body with an opening below is provided on the top surface of the suction chamber with a sound absorbing member having air permeability and noise reduction effect. [0004] Figure 5 It is a side sectional view showing the structure of such a conventional suction tool for an electric vacuum cleaner. Such as Figure 5 As shown, the suction member main body 101 is composed of an upper casing 102 constituting the upper portion of the suction member main body 101 and a lower casin...
