Extension pipe for vacuum cleaner

Abstract

The invention discloses an extension pipe for a vacuum cleaner, and belongs to the field of electrical appliances. The problem of large influences on an inner pipe due to arrangement of an electric wire on an extension pipe is solved. According to the technical scheme, the extension pipe mainly includes an inner pipe, an outer pipe and an electric wire, and the outer pipe sleeves the outside of the inner pipe; a first connector and a second connector are arranged at the two ends of the inner pipe correspondingly, the first connector includes a first communication hole in butt joint with the inner pipe, and the second connector includes a second communication hole in butt joint with the inner pipe; and the first connector and the second connector fix the outer pipe so that a wiring channelfor wiring the electric wire is formed between the outer pipe and the inner pipe, the first connector is provided with a first wiring terminal, the second connector is provided with a second wiring terminal, one end of the electric wire is connected to the first wiring terminal, and the other end of the electric wire is connected to the second wiring terminal. The extension pipe is mainly used forfacilitating the assembly of the extension pipe and reducing the influences of the arrangement of the electric wire on the inner pipe.

Description

technical field [0001] The invention relates to electrical appliances, in particular to an extension tube for a vacuum cleaner. Background technique [0002] Most of the existing vacuum cleaners are equipped with extension tubes for the convenience of users. When cleaning the ground or high places, the extension tubes can be connected between the main body of the vacuum cleaner and the suction head of the vacuum cleaner to increase the working radius of the vacuum cleaner. Because most of the existing vacuum cleaner suction heads are also provided with a motor that drives the roller brush, the main body of the vacuum cleaner needs to supply power to the motor. After connecting the extension tube, the motor needs to be connected to the power supply through the extension tube. [0003] In the prior art, the axial through hole for the power supply line is generally formed inside the extension tube. From the perspective of the cross section, the axial through hole will occupy t...

Problems solved by technology

[0003] In the prior art, the axial through hole for the power supply line is generally formed inside the extension tube. From the perspective of the cross section, the axial through hole will occupy the inner hole space inside the extension tube for air flow, resulting in the shape of the inner hole of the extension tube It becomes irregular, and the garbage is easily affected when it passes through the extension tube, and it is easy to form a hygienic dead angle on the partition separating the axial through hole and the inner hole, which further affects the dust collection effect

In addition, most of the existing extension rods are integrally injection-molded with plastic parts. Due to the need for injection-molded wiring channels, molding is difficult, and the obtained extension rods are heavy, with poor appearance and poor overall user experience.
