Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner in which a dust collection box has an opening for disposing of dust that can be opened and closed by a lid.

Conventionally, an opening for disposing of dust was provided in a dust collection box that was removably connected to the main body with a built-in electric blower.
In addition, a vacuum cleaner in which the opening was opened and closed by a lid was constructed as shown in FIG. 4. That is, the hinge device 4 of the lid body 41
2 is first screwed to the lid 41, then screwed to the dust collection box 43, and the lid 41 and dust collection box 43 are screwed together.
were combined. Also, a buckle claw 44 is slidably held on the lid 41 or the dust collection box 43 and is used to connect the two to keep the lid 41 in the closed state.
A button 45 for disengaging the buckle claw 44 from the dust collection box 43 is held by the dust collection box 43 and a handle 46 attached above the dust collection box 43. . To assemble these, the hinge device 42 and the lid 41 are attached to the dust collection box 43, and then,
Since a button 45 is set at the upper end of the buckle pawl 44 and a handle 46 is further attached,
The button 45 had to be supported, making assembly very difficult.

The present invention solves the above-mentioned conventional drawbacks and provides a vacuum cleaner that is easy to assemble.

To this end, the present invention provides a dust collection box having an opening facing the surface that is connected to the main body, a lid body that covers this opening so that it can be opened and closed, and a buckle button opening that is attached to the upper part of the dust collection box and located in the front. A handle with a
A hinge device consisting of a hinge shaft that connects the hinge fitting via a hinge spring that biases the lid in the opening direction, and a stepped part that is inserted from below into the buckle button opening and is biased by the buckle button spring and is integrally formed. The buckle button and the buckle button spring are sandwiched between the handle and the hinge plate to form the handle, buckle button, buckle button spring, and hinge device into a unit. and is screwed onto the dust collection box.

This function allows the lid, hinge device, buckle button, buckle button spring, and handle to be easily assembled and connected to the dust collection box by unitizing the dust collection box.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

1 is the main body with built-in electric blower 2, 3 is the buckle 4
This is a dust collection box that is detachably connected to the main body, and has a large opening 5 and a small opening 6 on its front surface.
7 is a wall formed integrally with the dust collection box and partitions the large opening 5 and the small opening 6; 8 is a filter frame having a primary filter 9 for collecting coarse dust; It is pressure welded and dust tight. Reference numeral 11 denotes a secondary filter for collecting fine dust. Vibration is applied by a slider 13 slidably held in the center of the filter holder 12, and the fine dust attached is collected at the bottom of the dust collection box 3. It falls into a deposition chamber 14 communicating with the opening 6 and is deposited thereon.
Further, the filter frame 8, the secondary filter 11, and the filter holder 12 are integrated with a packing B14 and inserted into the dust collection box 3.

15 is a handle attached above the dust collection box 3 for carrying the dust collection box 3, and a buckle button 1 is attached to the front.
It has a buckle button opening 17 for slidably holding the button 6. The buckle button 16 includes an operating portion 18, a buckle button body 19, and a buckle button pawl 2 protruding from the buckle button body 19.
0, and the stepped portion 21 of the buckle button body 19 prevents it from protruding above the buckle button opening 17 of the handle 15.

Reference numeral 22 denotes a front lid, which has an intake port 23 near the center to which a hose is connected. Reference numeral 24 denotes a front cover plate, which is screwed to the front cover 22 via a gasket C25. A buckle claw 26 is held between the front cover 22 and the front cover plate 24 so as to be slidable upward and downward, and is normally biased upward by a buckle claw spring 27.

The hinge fitting 28 is rotatably fixed to a hinge abutment plate 31 by a hinge shaft 30 to which a hinge spring 29 is attached, and is also screwed to the front cover 17.

The hinge support plate 31 has a buckle button spring seat 33 for supporting the buckle button spring 32 at the rear, and
It is screwed to the lower side of the buckle button opening 17 of the handle 15. In these assemblies, the hinge metal fitting 28 and the hinge abutment plate 31 are pivotally supported by a hinge shaft 30 through which a hinge spring 29 is inserted. Next, the buckle button 16 with the buckle button spring 32 inserted is inserted into the buckle button opening 17 of the handle 15, and the lower end of the buckle button spring 32 is supported by the buckle button spring seat 32 of the hinge plate 31. and screw the handle 15. Furthermore, by holding the buckle claw 26 and screwing the front cover 22 connected to the front cover abutting plate 24 and the hinge fitting 28, these parts are made into a unit as shown in FIG. These unit parts are fixed to the dust collection box 3 by inserting the hinge contact plate wings 31a projecting on both sides of the hinge contact plate 31 into the hinge grooves 31b of the dust collection box 3, and screwing them together at the same time.

The buckle claw 26 has a buckle claw piece 35 whose lower end engages with an engagement protrusion 34 provided on the bottom surface of the dust collection box 3. Normally, the buckle claw 26 is urged upward by the buckle claw spring 27, and the buckle claw piece 35 engages with the engagement protrusion 34, so that the front cover 22 is closed to the large opening via the rubber gasket 25. 5. Covers the small opening 6. When the operation part 18 of the buckle button 16 is pushed downward with a fingertip, the buckle button 16 slides downward, the buckle button pawl 20 slides the buckle pawl 26 downward, and the buckle pawl piece 35 slides down on the dust collection box 3. After being disengaged from the engagement protrusion 34, the front cover 22 and the like are rotated about the hinge shaft 30 by the bias of the hinge spring 29 to the position shown by the imaginary line in FIG. 1, and are in the open state.

In the above configuration, when the buckle button 16 is slid downward, the buckle button protrusion 20 moves between the front cover 22 and the front cover abutting plate 24.
The buckle claw 26, which is slidably held by the buckle claw 26, is pushed down, and the engagement between the buckle claw piece 35 and the engagement claw 34 is released.
At this time, the front lid 2 is biased by the hinge spring 29.
2. The front cover plate 24 and the like rotate around the hinge shaft 30 and are opened to the large opening 5 and small opening 6 of the dust collection box 3.

The buckle button 16 and buckle button spring 32 are attached to the handle 15
It is supported by the buckle button opening 17 and the buckle button spring seat 33 of the hinge backing plate 31, and since the handle 15 and the hinge backing plate 31 are screwed together, it can be made into a unit. It is not necessary to insert it into the buckle button opening of the handle 15 while supporting it and to attach it to the dust collection box together with the handle, making assembly easy. Furthermore, this unit and the front cover 22
By tightening the screws, the unit can be expanded and assembled into the dust collection box 3.

As described above, according to the present invention, the hinge device, the buckle button, and the buckle button spring for rotating the lid body relative to the dust collection box to open the dust collection box, and the hinge device, the buckle button and the buckle button spring, and the buckle button and the buckle button spring. By making it into a unit by holding it with the handle, it is possible to extremely easily attach and assemble it to the dust collection box, and as a result, it is possible to provide an inexpensive vacuum cleaner.
