Description

[Detailed Description of the Invention] The present invention is an improvement in the bumper attachment to the lid body that opens and closes the waste dust opening of the dust collection case.

Conventionally, the bumper of this type of vacuum cleaner was mostly attached to the lid using screws. However, this method not only required special work and tools to tighten the screws, which was time-consuming, but also caused the screw heads to stick out, resulting in a poor appearance. In addition, an adhesive was applied to prevent the end of the bumper from lifting off the lid, but this adhesive oozed out, causing the lid to get dirty.

The present invention solves these conventional drawbacks, and its structure and operation will be described below with reference to the accompanying drawings.

In the figure, 1 is a dust collection case that is detachably connected to the vacuum cleaner body (not shown) that has a built-in fan motor etc. via a buckle.The front and back of the case are open, and one front opening can be opened and closed. A removable filter device (not shown) is provided in the other opening of the lid body 2, respectively. 3 is an air intake port formed in the lid body 2; 4 is a handle of the dust collection case 1 having an opening/closing operation button 5 of the lid body 2 and an operation button 6 of the buckle;
7 is a bumper of the dust collection case 1, and 8 is a bumper of the lid body 2.

Next, a configuration for attaching the bumper 8 to the lid body 2 will be explained. The bumper 8 has some degree of elasticity, has a shape that follows the front surface of the lid body 2, and has L-shaped bent pieces 10 each having a locking hole 9 at both ends. On the other hand, recesses 12 having protrusions 11 protruding from the bottom are formed at the edges of the lid 2 and at opposite positions on both sides. The widths of the recess 12 and the bumper 8 are approximately the same, and the depth of the recess 12 is approximately the same.
The thickness of the bumper 8 and the height of the protrusion 11 are also set approximately equal. Reference numeral 13 denotes an inclined surface formed on the outside of the upper part of the protrusion 11.

In the above configuration, the bumper 8 can be attached to the lid body 2 by first aligning the bumper 8 along the front surface of the lid body 2, and then applying the bent piece 10 to the protrusion 11 and pressing it. That is, the bent piece 10 slides on the protrusion 11 using the inclined surface 13 as a guide, and during constant movement, the protrusion 11 engages with the locking hole 9, and the bent piece 10 closes in the recess due to its elastic restoring force. 12.

As described above, according to the present invention, the following excellent effects can be expected.

The bumper can be installed without much effort, greatly improving installation work efficiency.

Costs can be reduced because special mounting parts such as screws are not required.

There is no lifting of both ends of the bumper, so there is no staining of the lid body due to the use of adhesive.

Due to the dimensional relationship between the recess and the bumper, there is no gap between the dust collection case and the lid, and the dust can be kept tightly.

Claims (1)

[Scope of utility model registration request] In a case where an opening for waste dust is formed in the front of the dust collection case, and this opening is opened and closed with a lid, a bottom portion is installed at opposite positions on both sides of the edge of the lid that comes into contact with the opening end of the dust collection case. A recess with a protrusion formed therein is formed, and both ends of the bumper along the front surface of the lid body are fitted into the recess, and holes formed at both ends are engaged with the protrusion, and the thickness of the bumper is equal to the thickness of the bumper. A bumper attachment device for a vacuum cleaner, in which the depth of the recess and the height of the protrusion are set to be approximately the same, and an inclined surface is formed on the outside of the tip of the protrusion.
