Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner in which the opening of a dust collection box is opened and closed by a lid.

2. - Conventional configuration and its problems Conventionally, in vacuum cleaners in which the dust collection box and the main body are detachable and the dust is disposed of through the opening of the dust collection box, a first As shown in the figure, a packing 1 made of a material such as rubber or soft vinyl chloride was provided, and a lip 2 formed on the backing 1 was pressed against an opening wall surface 3 of the dust collection box. However, in this configuration, the lip 2 and the front surface 4 of the wall surface 3
A V-shaped space is created between them, and the dust 5 enters this space in a wedge shape. Then, insert the hose into the hose insertion port provided on the lid body, and shake the hose widely from side to side to release the lip 2.
This has the disadvantage that a gap is created between the front surface 4 and the dust box 4, and the dust that has entered in a wedge shape and the dust in the dust collection box, especially fine dust, can fall and re-stain the floor surface or carpet after cleaning. Ta.

OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks, and ensures that the opening of the dust collection box and the lid are dust-tight, thereby preventing dust from leaking from that area.

Structure of the Invention The vacuum cleaner of the present invention includes a dust collection box that is detachable from a main body having a built-in electric blower and has a coarse dust outlet and a fine dust outlet on the side opposite to the attachable/detached surface to the main body. The dust collection box has a front cover that can freely open and close the coarse dust discharge port and fine dust discharge port, and a front cover that has an intake port for connecting a hose approximately in the center. It has a front cover plate equipped with a gasket that tightly connects the box's coarse dust outlet and fine dust outlet. The intended purpose is achieved by forming a lip protrusion with a substantially chevron-shaped cross section that presses against the inside of the wall that forms the fine dust outlet, and a thin lip that is approximately arc-shaped and presses against the wall. .

Description of examples Examples will be described below based on the accompanying drawings.

In FIGS. 2 and 3, 11 is a main body of a vacuum cleaner incorporating an electric blower 12, and 13 is a dust collection box that is detachably connected to the main body 11 with a buckle 14, and has an opening A16 and an opening B16 on the front side. Reference numeral 17 denotes an inner wall forming an opening A16 and an opening B16, which is molded integrally with the dust collection box 13. 18 is a filter frame having a primary filter 19 for collecting coarse dust;
It is pressed against the packing A20 attached to the inner wall 17 and is tight. Reference numeral 21 denotes a secondary filter for collecting fine dust, which is vibrated by a slider 23 slidably held in the center of the filter holder 22 to filter the filter frame 18.
It is formed so that fine dust adhering to the side falls and is deposited in the deposition chamber 24 communicating with the opening B16. 25 is a gasket B that clamps the filter frame 18, secondary filter 21, and filter holder 22, and prevents air leakage between the inner surface of the dust collection box 13 and the main body 11 within the dust collection box 13. keeping. 26 is a handle attached above the dust collection box 13;
Reference numeral 7 denotes a buckle push button held in the buckle push button hole 28 in front of the handle 26 and formed to be slidable in the vertical direction.
It is formed of a push button pawl 3o that protrudes forward.

Reference numeral 31 denotes a front lid, which has an air intake port 32 for connecting a hose approximately in the center thereof. 33 covers the opening A15 and the opening 16;
The front lid 31 is fitted with a front lid contact plate that is attached around the inner wall 17 of the dust collection box 13 and the opening wall surface 36 of the bottom surface 34, and a packing 36 made of a material such as soft vinyl chloride or natural rubber that is air tight and dust tight. Screw II-, fitted. Reference numeral 37 is a buckle type that is held by the front cover 31 and the front cover plate 33 so as to be slidable in the vertical direction, and is biased in three directions by a buckle type spring 38. The lower end of the buckled buckle 37 is bent at a nearly right angle toward the dust collection box 13, and is engaged with the engaging claw 39 protruding outward on the front side of the bottom surface 34 of the dust collection box 13, thereby collecting the front lid 31. It has a buckle claw piece 4o that locks the dust box 13 in a closed state. Further, when the front cover 31 is in a closed state with respect to the dust collection box 13, the upper part of the buckle mold 37 is in contact with the push button pawl 30 of the buckle push button 27 from below. 41 is the handle 26
, a dust collection box 13, and a hinge device connected to the front lid 31.

Now, the operation part 2 of the buckle push button 27 is pressed against the buckle push button spring 42.
When 9 is pressed with the tip of a finger, the push button pawl 30 slides the buckle mold 37 downward, disengaging the buckle pawl piece 40 from the engagement pawl 39, and moves the front cover 31 to a horizontal position around the hinge shaft 42'. Open and rotate at around 1.

The gasket 36 has an inverted ■-shaped lip protrusion 43 that protrudes into the opening B16 against the opening wall surface 35 of the bottom surface 34 of the dust collection box 13 forming the opening B16, and a lip 44 that is pressed against the opening wall surface 36 in an arc shape. have

The lower surface 46 of the lip projection 43 is pressed against the opening wall surface 35.

In the above configuration, when the vacuum cleaner is put into use by inserting a hose into the intake port 32 and sucking in dust, the coarse dust is collected by the primary filter 19 and accumulated in the space above the inner wall 17. - The fine dust that has passed through the secondary filter 19 is transferred to the secondary filter 21.
However, by sliding the slider 23,
This secondary filter 21 is vibrated and falls into the deposition chamber 24. By the way, fine dust accumulates in the opening B16 when the vacuum cleaner is in use or when it is moved after use, or when the front cover 31 is opened and discarded. However, since the lip protrusion 43 of the gasket 36 is in pressure contact with the opening wall surface 35 in the small opening B16, fine dust tends to accumulate on the lip protrusion 43, the lip 44, and the opening wall surface 35. No fine dust will fall on the floor or carpet surface after cleaning.

Effects of the Invention As described above, according to the present invention, the waste dust opening of the dust collection box is closed with a lid, and the lid is provided with a gasket that tightens dust between the opening and the opening. In addition, this gasket has a lip that is approximately arc-shaped and thin, as well as a lip that is approximately chevron-shaped in cross section, so that dust does not fall from the dust-tight area, which is effective in preventing stains on floors, etc. It is something.
