Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner incorporating a detachable dust collection box.

Conventional structure and its problems Conventionally, in this type of vacuum cleaner, when inserting the dust collection box,
Problems such as incorrect insertion of the dust collection box may deform the backing between the dust collection box and the fan motor, or create a gap between the dust collection box and the packing, causing air leakage. was there. In addition, there was a difference in level or gap between the opening of the dust collection box and the main body of the vacuum cleaner, which caused air leakage and caused a bad appearance. In this way, problems such as air tightness have arisen due to improper installation of the dust collection box.Object of the InventionThe present invention solves such conventional problems, and aims to solve the problem of air tightness caused by incorrect installation of the dust collection box. This prevents deformation, gaps, and steps, and improves airtightness.

Structure of the Invention The vacuum cleaner of the present invention includes a vacuum cleaner body that includes a suction fan motor and a removable dust collection box provided on the suction side of the fan motor and having an opening for waste dust. It consists of a backing that is placed between the fan motor and the dust box to maintain airtightness, a front cover that freely opens and closes the opening of the dust box and has a hose insertion port, and a backing that is connected to the front cover. and a front cover backing plate equipped with a lid rubber that maintains airtightness with the opening of the dust collection box, and a flange portion that forms an airtightness maintaining surface with the lid rubber at the opening of the dust collection box. By providing a stopper for the dust collection box on the vacuum cleaner body, the air tightness between the dust collection box and the lid rubber is completely ensured. This is intended to improve airtightness with rubber and packing.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2, 1 is a vacuum cleaner body that has a built-in fan motor 2 and can be divided into upper and lower parts, 3
The dust collection box 6 includes a filter device 4 and a dust collection bag 6 which is discarded together with the collected dust, and is a removable dust collection box held by the main body 1 and is provided on the suction side of the fan motor 2. A dust collection bag outlet is provided on the front of the dust collection box 3,
A dust collection bag support plate 6 to which the dust collection bag 5 is attached is rotatably supported at the lower end thereof, and a flange portion 7 is provided on the outer periphery. Reference numeral 8 denotes a front cover which has a hose insertion port 9 and a handle 10, and is equipped with a front cover contact plate 12 having a lid rubber 11 attached to the outer periphery to maintain airtightness with the flange portion 7. It is rotatably supported on the lower front end of the dust collection bag, and is locked with a buckle 13 to open and close the dust collection bag outlet. The fan motor 2 and the dust collection box 3 are separated by a partition wall 16 having a ventilation hole 14, and the motor Zaport rubber 16 and a backing 17
They are in airtight contact with the partition wall 15 via the partition wall 15.

To attach and detach the dust collection box 3, as shown in FIG. It can be rotated [7] freely in the open state. As shown in FIGS. 4 and 6, the top and bottom surfaces of the main body 1 are provided with stoppers 20 made of flat surfaces and ribs, with which the flange portion 7 comes into contact when the dust collection box 3 is inserted.

In the above configuration, as shown in FIG. 4, the lid rubber 1 is
1 is widened to prevent the lip 21 of the lid rubber 11 from coming into contact with the fitting part between the main body 1 and the dust collection box 3, thereby ensuring reliable air talopage. In addition, by providing a stopper 20 inside the main body 1 that comes into contact with the flange portion 7,
When the dust collection box 3 is inserted, the rear surface of the dust collection box 3 does not apply excessive force to the gasket 17, so the gasket 1
7 can be prevented from becoming sagging, and also ensure airtightness between the dust collection box 3 and the lid rubber 11 by eliminating steps and gaps that occur between the main body 1 and the dust collection box 3 due to insufficient or insufficient insertion. It is.

Effects of the Invention As described above, the present invention provides a flange portion on the outer periphery of the opening of the dust collection box, thereby making it possible to widen the airtightness-maintaining surface, thereby achieving reliable air tightness, and ensuring that the flange portion and the abutting surface are wide. By providing a contacting stopper inside the vacuum cleaner body, it is possible to prevent incorrect insertion of the dust collection box, eliminate deformation of the backing, and eliminate steps and gaps that occur between the vacuum cleaner body and the dust collection box, ensuring airtightness. In addition, the dust collection box can be inserted correctly and reliably, and the six-page backing can be prevented from fading due to creep.
