Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a versatile surface treatment apparatus driven by a vacuum cleaner. The surface treatment device according to the present invention can perform polishing, cleaning, polishing, etc. by exchanging attachments.
It can be used for many purposes such as puffing or pine surge.

[Prior Art] A conventional surface treatment apparatus of this type includes an electric motor, a reduction gear connected to the drive shaft of the electric motor, and an attachment detachably connected to the output shaft of the reduction gear.

[Problems to be solved by the invention] Such surface treatment equipment has an electric fl unit and a speed reducer integrated into the main body of the equipment, so it is large in size and has a large weight ω, making it difficult to work. It was very tiring and difficult to work for long hours.

Furthermore, conventional surface treatment apparatuses are unfavorable from a hygienic point of view because workers inhale dust and the like generated during the work.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems of the conventional device.

For this reason, the present invention provides a hollow casing in the form of a truncated cone, which has a large number of openings on the upper side surface and has a hose connector protruding from the side wall for connecting to a hose of a vacuum cleaner; a cover attached to the upper part of the casing, a hollow cylindrical sleeve fixed within the casing, a diaphragm provided between the lower edge of the casing and the lower end of the sleeve, a brush fixed to the lower edge of the sleeve and around the lower edge. A multi-purpose surface treatment driven by a vacuum cleaner, characterized in that it comprises a base having a base and a turbo fan unit 1 fixed in the base and rotationally driven by the suction force of the vacuum cleaner. It provides equipment.

[Function] The surface treatment device according to the present invention generates vibration by rotating a turbo fan provided with an eccentric weight by using the suction force of the vacuum cleaner by connecting it to a suction hose of a vacuum cleaner. By attaching various attachments to the bottom of the device, it can be used for many purposes such as polishing, cleaning, polishing, puffing, and pine surge.

[Example] Next, an example of the present invention will be described in detail with reference to the accompanying drawings.

The versatile surface treatment device according to the invention, shown in cross-section in FIG. 1, comprises a hollow casing 1 in the form of a frusto-cone. This casing is provided with a number of openings 2, preferably rectangular, on the upper side and a vacuum cleaner (
A cylindrical hose connector 3 for connecting to a hose (not shown) is provided in a protruding manner. This connector also serves as a handle when working.

A cover 4 is rotatably attached to the upper part of the casing 1. This cover 4 is provided with a hose connector 5 on the top. The inner diameter of this connector is the same as the inner diameter of the connector protruding from the casing, and when used, a suction hose of a vacuum cleaner is connected to one of the connectors. The unused connector is also closed with a cap 6 that can be inserted into it. The cover 4 also has a large number of fingers that can cover the large number of openings 2 provided on the upper side of the casing. ! IS7, and the protrusion 8 of the finger 7 engages with a groove provided below the opening 2 of the casing, so that the cover is rotatably attached to the upper part of the casing.

A hollow cylindrical sleeve 9 is fixed within the casing 1, and this sleeve has an upper flange 10 and a lower flange 11.
These flanges are interconnected by multiple spiders 12. The sleeve 9 is provided with a number of vent holes 9a in its cylindrical side wall.

A thin diaphragm 13 is attached between the lower edge 1a of the casing 1 and the lower end of the sleeve 9, that is, the lower flange 11. Preferably, this diaphragm is made of an elastic material, especially rubber.

A base 14 is attached to the lower end of the sleeve, ie, the lower flange 11, and this base is provided with an annular wall 15 in the center of its upper part, in which a circular hole 16 is bored. Further, a brush 17 is installed around the lower edge of the base, and this brush prevents dust from scattering to the outside of the apparatus during operation.

When installing the base, the inner circumferential portion of the annular wall portion 15 is attached to the diaphragm 1.
3, thus achieving an airtight seal between the base and the casing 1.

A turbo fan unit 18 is mounted within the base 14. This turbo fan unit includes a bottom plate 21 having a circular recess 19 and at least two suction ports 20, 208 that open tangentially to the recess, and an annular shape rotatably attached to the bottom plate via a bearing 22. It is equipped with a turbo fan 23. The turbo fan unit 18 is attached with its bottom plate 21 maintaining a constant distance G from the outer edge of the base 14. An eccentric weight 24 is attached to the turbo fan 23 so as to be eccentric from the rotation axis of the fan.

The turbo fan generates airflow as shown by the arrow in Figure 1 by the suction of the vacuum cleaner, and the suction port 20.208
It sucks in more air and rotates at high speed. The turbo fan generates vibrations when rotating at high speed due to the eccentric weight 24 attached thereto.

To adjust the suction force and vibration force, the intake of outside air is controlled by rotating the cover 4 and partially covering the opening 2 of the casing with the fingers 7 of the cover.

The surface treatment apparatus according to the present invention utilizes this vibration to perform polishing, cleaning, polishing, or puffing, and at the same time sucks up dust, paint particles, and other dust generated during the operation.

On the bottom surface of the base 21, Velcro (trade name) tape, which is generally referred to as Velcro tape, is attached over almost the entire surface.

A sheet that engages with the Velcro tape on the bottom of the bottom plate 21 is attached to the center of various attachments (not shown) such as sandpaper used as a sander, a pad used as a poly lasher, and a pine surge pad used for pine surge. The attachment can be quickly Ha.

[Effects of the Invention] Since the present invention is configured as detailed above, it is extremely lightweight and more compact than conventional devices that incorporate a dedicated electric motor and reduction gear. [f
I can do 3J.

Furthermore, the surface treatment device according to the present invention can suck up dust and paint particles generated during surface treatment work, so that workers can work without inhaling particles that are harmful to their health and can work without getting dirty. .
