Battery Powered Long-Lever Sander

Abstract

The utility model discloses a battery powered long-lever sander. The battery powered long-lever sander includes a sander head assembly and a handle. The sander head assembly is connected to the handle and includes a housing and a sanding disc that is disposed in the housing. The battery powered long-lever sander further includes a driving system connected to the sanding disc and configured to drive the sanding disc to run. The driving system is electrically connected to a driving power source, and the driving power source is a battery pack so that the sander can be used without limitations of plugging of a power wire and thus can be used more conveniently.

Description

BACKGROUND OF THE INVENTION[0001]The utility model relates to the technical field of sanders, and more particularly to a battery powered long-lever sander.[0002]Before plastering, painting or wallpapering of a wall, the wall needs to be sanded and cleaned. As a mature technology, wall sanders have been extensively used. In the prior art, wall sanders are mostly used for sanding a wall, and there may exist some defects as follows when they are used for sanding a ceiling: (1) To facilitate omnidirectional sanding of a ceiling and a wall, a sanding disc and a handle are movably connected to each other. When sanding a ceiling, the sanding disc has only one stressed side with the ceiling, and the load-bearing side comes into contact with the ceiling while the other side of the sanding disc will drop down. When sanding a ceiling, it needs more effort to operate due to uneven stress. (2) An existing sander with a dust suction device may have a poor dust suction effect due to limitations of...

AI Technical Summary

Benefits of technology

This patent describes a device called a sanding disc suspending device that is used to evenly sand hard surfaces. The device includes a LED strip lamp and a transparent lampshade that are connected together with a transparent encapsulating material, making them into an integrated structure. The device also includes a snap-in device for elastic connection between the LED strip lamp and the supporting arm, which ensures that the sander head remains parallel to the wall and the working center of gravity is balanced, making it easier to operate and comfortable for the operator. Additionally, the device uses a battery pack as a power source, making it convenient and easy to use. The device also has a dust suction fan blade that improves the dust suction effect. The handle of the device is flexible and can be lengthened and shortened with high flexibility. The patent aims to provide a novel design that is practical and extends the functionality of the device.

Problems solved by technology

When sanding a ceiling, it needs more effort to operate due to uneven stress.

(2) An existing sander with a dust suction device may have a poor dust suction effect due to limitations of the mechanism.

Secondly, a sanding disc of the wall sander has an abrasive surface structure and is a flat surface as a whole with single structure and function.

After being used for a long time, the sanding disc may have a rubbing surface apt to be damaged by the sanding disc and may be difficult to replace.

(3) An LED (Light Emitting Diode) strip lamp and a transparent lampshade in a lighting structure of an existing sander are structured separately, and during use, dust still can fall into the transparent lampshade and on the LED strip lamp, affecting the use of the LED strip lamp.

(4) Due to an unreasonable design of the dust suction mechanism, the dust suction effect may not be obvious.

(5) The handle cannot be extended, resulting in limitations of use.
