Description

[Detailed Description of the Invention] Industrial Application Field The present invention includes a dust lid that is detachably attached to an upper opening of a dust collection chamber;
This invention relates to a vacuum cleaner equipped with a buckle for locking the dust cover to the main body in a closed state.

Conventional Structure and Problems Conventionally, in this type of vacuum cleaner, as shown in FIG. The opening of the dust collection chamber 3 is provided with a dust lid 4 that can be opened and closed freely, and a buckle 5 for locking the dust lid 4 in a closed state.

The dust cover 4 has a hook part 4a on the rear part for hooking on the upper part 6 of the main body, and a part 4b on the front part for hooking on the buckle 6, and is attached to the opening on the lower part 1 of the main body. It is.

Further, the buckle 5 is installed at the lower part of the main body 1 and the front cover 7 so as to be able to rotate back and forth.
The upper end has an operation part 5a for hooking a finger and rotating it.
is formed.

The operating portion 5a of the buckle 6 is generally formed into a vertical surface or a vertical concave surface so that it can be easily hooked with a finger.

Therefore, when operating the buckle 5 to open the dust cover 4, it is easy for your finger to get caught and pull it, which often applies more force than necessary to the pivot point or stopper of the buckle 6, causing damage to related parts. There was a problem that this led to unsafe behavior. In addition, as a countermeasure to this problem, some vacuum cleaners have been strengthened by making the related parts larger, but these have had the disadvantage of making the vacuum cleaner itself larger.

Note that 8 is a handle placed at the front of the vacuum cleaner body, and if the buckle 6 is made larger for reinforcement or if the rotation range of the buckle 6 is expanded, problems with the handle 8 will occur.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a vacuum cleaner that is easy to operate with a buckle and has improved safety.

Structure of the Invention In the vacuum cleaner of the present invention, the operating surface of the buckle that locks the dust cover in the closed state is formed into an inclined surface that is easy to catch a finger on, and when it is rotated toward the front, the inclined surface is close to horizontal. This prevents the fingers from coming off the operating surface and applying more force than necessary.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 6, reference numeral 20 denotes the lower part of the main body, which has an upward-opening dust collection chamber 21 on the front side and an electric blower chamber 24 containing an electric blower 23 on the rear side partitioned by a partition wall 22.

Reference numeral 26 denotes a suction port 2 arranged at the front of the dust collection chamber 21 and connected to the hose 26 through a front cover fixed to the lower part 20 of the main body.
7.

A dust collection bag 28 is attached to the dust collection chamber 21, and a removable dust lid 29 is attached to the upper opening and is locked with a buckle 3o.

A dust indicator 31 for detecting the amount of collected dust is arranged at the rear part of the dust lid 29, and a handle 32 for carrying the dust lid 29 is formed at the front part so as to match the handle 33 formed at the front part of the lower body 20. It is set to 20 on the bottom of the main body.
By attaching ii29, a handle as a main body of the vacuum cleaner is formed.

An electric blower 24 and a cord winding device (not shown) are housed therein by attaching an upper body 34 to the rear upper part of the lower body 2o.

3.Haba, Paa, front, 84 bodies T20 and the main body.
It is installed between the door 34 and the dust lid 29.

36.3γ is a tananozzle placed on the upper part of the main body 34,
The gap nozzle is further covered with a cuff nozzle 38 that can be opened and closed, and the upper surface is configured to be a clean surface without any irregularities.

Reference numerals 39 and 40 are front wheels and rear wheels for movement disposed at the lower part of the lower body 20.

As shown in FIGS. 4 and 5, the buckle 3o has a shaft 30a on both sides, an operation part 30b on the upper part that can be hooked with a finger and pulled in the direction of the arrow, and a coil spring 41 on the lower part that biases in one direction. The spring bearing forms a portion 30c, and is rotatably held by the bearing portion 20a of the lower body 20 and the shaft support portion 25a of the front cover 25.

Further, below the operation part 30b of the buckle 30, there is a
The hook formed in M29 has a locking part 30d that is hooked onto the part 29a and fixed.

29b is a buckle 30'f: a concave portion 29 formed in the dust cover for easy operation, and 29c is a protrusion for hooking the rear part of the dust cover 29 onto the hook portion 34a formed on the main body 34.

As shown in FIG. 4, the operating portion 30b of the buckle 30 is formed on an inclined surface so that it can be easily rotated by hooking a finger thereon.
When rotated, the inclined surface of the operating portion 30b becomes nearly horizontal as shown by the dotted line, and the finger is naturally removed.

Using the above configuration, when attaching and detaching the dust collection bag 28, the buckle 30 is rotated to release the lock and the dust cover 29 is removed. Next, the dust collection bag 28 is removed from the bag support 42, taken out from the dust collection chamber 21, and replaced with a new dust collection bag.

Effects of the Invention As described above, in the configuration of the present invention, the finger hook provided to facilitate the operation of the buckle is formed with an inclined surface to make it easier to fit the pad of the finger. At times, the operation part of the inclined surface is set so that it is almost horizontal, so that the finger naturally comes off the operation part, and abnormal force is applied to the buckle shaft and its bearing part, causing damage. There is no
It has improved operability, reliability, and safety.

Therefore, there is no need to increase the size of the lock and related parts, and the vacuum cleaner body also has the advantage of being able to be made smaller.
