The connection member is formed with an insertion part in the shape of a tube, so that the insertion part of the connection member is inserted by an accessory from the front end of the insertion part by pressing the accessory.
In the vacuum cleaner, the most important function is the dust-collection force. In spite of this fact, the conventional vacuum cleaner has a disadvantage in that there has been no equipment to measure the dust-collection force of the vacuum cleaner by visual inspection, and the absorption force is simply regarded as the dust-collection force.
On the other hand, the conventional vacuum cleaner has another disadvantage that the absorption force becomes weaker when the filter, which is installed in a dust collection box, becomes clogged. In this case, even though it is easily checked that the dust collection force becomes reduced relative to the absorption force, it is still difficult to actually measure the dust collection force of the vacuum cleaner. Further, filters are usually changed one after another after a predetermined time lapses.
The present invention overcomes the disadvantages of the conventional vacuum designs and it is an object of the present invention to provide a dust collection tester for a vacuum cleaner that can or conveniently clean by vacuum absorption, floors, carpets, sofas, etc., and which makes it possible to visually confirm that the dust collection force of the vacuum cleaner and the dust collection states according to absorption force of the vacuum cleaner.
In order to achieve the above objects of the present invention, a dust collection tester to be coupled with a vacuum cleaner, in which a dust collection member having a vacuum motor and a filter is installed in a main body and formed with an insertion opening portion having protrusions at one side of the main body. The device includes a lower body formed with a transparent material and having a hinge part at one side, a locking part at the other side, and an insertion part formed with grooves to be inserted into the insertion opening portion of the vacuum cleaner by locking the protrusion of the opening portion of the vacuum cleaner in the grooves of the insertion part of the lower body, and an upper body formed with a transparent material and symmetrically to the lower body and having a hinge part at one side, a locking piece at the other side, and a dust collection hole, wherein the hinge parts of the lower body and the upper body are connected by a hinge pin, and the locking part of the lower body is coupled with the locking piece of the upper body, such that the lower body and the upper body are coupled together.
The present invention will become better understood from the detailed description given herein with reference to the accompanying drawings which are given by way of illustration only, and thus are not limited of the present invention, and wherein:

A dust collection tester for a vacuum cleaner according to preferred embodiments of the present invention would be explained in detail herein with reference to the accompanying drawings.
A vacuum cleaner includes a dust collection member connected to a vacuum motor and a filter, the cleaner having a dust collection box 2 in a main body 1. The vacuum cleaner includes an insertion-opening portion 3 having protrusions 4 extending from one side of the main body 1.
A dust collection tester includes a lower body 5 formed with transparent material and having a hinge part 6 at one side, a locking art 11 at the other side, a dust collection conduit 9, and an insertion part 7 formed with grooves 8, such that the insertion part 1 can be inserted into the insertion opening portion 3 of the vacuum cleaner by locking the protrusion 4 of the insertion opening portion 3 of the vacuum cleaner in the grooves 8 of the insertion part 7 of the lower body 5.
The dust collection tester includes an upper body 12 formed with a transparent material and substantially symmetrical to the lower body 5. The upper body 12 includes an insertion part 13 provided with locking grooves, a hinge part 14 at one side, a locking piece 17 at the other side, and a dust collection conduit 15.
The hinge part 6 of the lower body 5 and the other hinge part 14 of the upper body 12 are connected by the hinge pin 16, and the locking part 11 of the lower body 5 is coupled with the locking piece 17 of the upper body 12, thereby the lower body 5 and the upper body 12 are coupled together.
All of the lower body 5 and the upper body 12, need not be formed with transparent material except for portions that would permit a user to externally to see through the transparent portions to view a dust collection net 10 and a filter 18. Also, even though the lower body 5 and the upper body 12 are in the shape of circle in FIG. 1 to FIG. 5, the present invention is not limited thereto but any modification, for example, square, pentagon etc. may be made.
According to the present invention as described above, the lower body 5 and the upper body 12 are preferably formed of transparent materials and provided with the hinge parts 6, 14, the insertion parts 7, 13 respectively having grooves 8, and the dust collection conduits 9, 15 symmetrically in pairs, so that the lower and upper bodies 5, 12 can be formed with only one metallic mold and coupled together facing each other to compose a tester. The lower and upper bodies 5, 12 are opened and/or closed by the hinge pin 16 installed on the hinge parts 6, 14. The lower body 5 is provided with the dust collection net 10 on which to place the filter 18, and the locking part 11, and the locking piece 17 (formed on the upper body 12) is locked in the locking part 11 of the lower body 5, thereby finishing the assembly of the dust collection tester.
