Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric vacuum cleaner that sucks in dust and cleans the inside of a general household or automobile.

Conventional Technology Conventionally, in this type of electric vacuum cleaner, the filter was manually pushed into the dust case.

Problems that the invention aims to solve In this conventional configuration, the filter is pushed in too much, reducing the volume of the dust case.
On the contrary, there was a problem in that insufficient pushing caused instability such as a gap being created between the inner surface of the dust case and the outer periphery of the opening of the filter, and that the filter was likely to fall when removed from the dust case.

This invention solves these problems,
The purpose is to stably insert the filter into the dust case and to prevent the filter from falling.

Means for Solving the Problem In order to solve this problem, the present invention has a main body case containing a rotary vane and a motor for driving the rotary vane, and a main body case located on the suction side of the rotary vane and detachable from the front of the main body case. a rear-open dust case that is freely coupled; a filter installed in the dust case and held in place by a rib in the dust case and a part of the front wall of the main case; In order to maintain the combined state of the main body case and the dust case, a stopper is movably attached to the dust case side, and this stopper has a filter holding piece that retracts from the back side of the filter in response to the movement of the stopper. It was formed.

Operation In the above configuration, the filter is positioned at a predetermined portion within the dust case by the rib and the front wall of the main case. Furthermore, when the dust case is removed from the main body case, the filter holding piece of the stopper prevents the filter from being accidentally removed.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. In the figure, 1 is a main body case, and this main case 1 includes a switch 2, a motor mounting plate 3, a motor 4, a power supply battery 5, and a battery pressing spring 6.
and a rotating blade 7 driven by the motor 4
Built-in. Further, the main body case 1 has a locking pawl 8 at the upper end of the front surface and a locking pawl 9 at the lower end of the front surface. 10 is the front wall of the main body case 1. 11
is a dust case, which has a filter 12 and a check valve 13 inside, a stopper 15 that swings up and down about a fulcrum 14, and a push spring 16 at the top, and a locking spring 16 at the bottom. It has a hole 17. Further, the front part of the dust case 11 is provided with a suction port 18 for sucking in dust. 19 is a filter holding piece provided on the stopper 15.

Next, the operation will be explained. When attaching the dust case 11 to the main body case 1 as shown in FIG. After inserting the dust case 11 into the slope part of the locking claw 8 on the upper part of the main body case 1.
When the stopper 15 attached to the main body case 1 is pressed against the stopper 15, the stopper 15 swings upward, and then passes over the locking pawl 8 of the main body case 1 and the stopper 15
is swung downward by the elasticity of the push spring 16 and is locked to the back side of the claw. At this time, the area around the opening of the filter 12 is pushed in by the front wall 10 of the main body case 1, and the filter 12 is housed in a fixed position. Next, when the dust suction is finished and the main body case 1 and dust case 11 are removed, a stopper 15 is installed to prevent the filter 12 inside the dust case 11 from falling naturally.
It is locked with a filter holding piece 19 provided on the filter.

FIG. 2 shows a state in which the main body case 1 and the dust case 11 are assembled. As shown in this figure, the area around the opening of the filter 12 is held between the ribs inside the dust case 11 and the front wall of the main case 1, and is fixed by the locking claw 9 of the main case 1 and the stopper 15 of the dust case 11. This is done stably.

Effects of the invention As described above, according to the invention, since the position of the filter in the dust case is determined mechanically,
There is no reduction in the volume of the dust case due to pushing the filter in too much, or there is no gap between the filter opening and the inner surface of the dust case due to insufficient pushing, and stable dust suction is performed, and the filter holding piece provided on the stopper prevents the dust case from being separated. This prevents the filter from accidentally falling off and prevents dust from scattering inside.
