Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner that hygienically disposes of dust by using an impermeable bag (hereinafter simply referred to as a bag) such as a plastic bag. If the plastic bag or the bypass passage of the dust collection case is blocked when attached to the dust outlet of the vacuum cleaner, the plastic bag will stick to the filter while the vacuum cleaner is running, and the vacuum cleaner's functionality will be paralyzed. Therefore, even if the bypass passage is blocked when a plastic bag is attached, when the dust collection case is attached to the main body using the rod provided in the bypass passage, the plastic bag can be torn to ensure its full functionality. purpose.

Conventionally, in vacuum cleaners that use plastic bags to dispose of dust, and which do not have a bypass passage, the bags are packed into small pieces and placed inside the dust collection case to prevent them from adhering to the filter while the vacuum cleaner is operating. It had to be fixed. Additionally, vacuum cleaners with bypass passages have the disadvantage that they must be installed with care so as not to cover the bypass passage with the attached bag.

The present invention aims to solve the above-mentioned conventional problems and provide a vacuum cleaner with high usability.The structure of the present invention will be explained below with reference to the drawings shown as examples.

Reference numeral 1 denotes a main body case, in which an electric blower 2 is built-in. Reference numeral 3 denotes a dust collection case coupled to the main body case 1, which can be detached with a buckle 4. An intake port 5 and a dust exhaust port 6 are provided on the front surface of the dust collection case opposite to the joining surface of the dust collection case 3 and the main body case 1. 7 is the front cover and the buckle 8 connects the dust collection case 3
is removably connected to. Reference numeral 9 denotes a front cover contact plate, which is fixed to the front cover 7 via a rubber gasket 10. Filter 11 is rubber gasket 12
It is removably attached to the rear opening of the dust collection case 3 through the holder while maintaining airtightness. 13 is a bypass passage formed so as to communicate from the filter 11 side of the dust collection case to the front cover of the dust collection case;
The pressure in front of the electric blower 2 and the pressure in the outer peripheral space of the dust exhaust port 6 are made equal. Reference numeral 14 denotes a rubber gasket that air-tightly connects the dust collection case 3 and the front cover 7. The front cover contact plate 9 has a ventilation hole 15 on the outer peripheral side of the dust exhaust port 6, and ventilation holes 16 and 17 on the inner peripheral side. When the front cover 7 with the front cover contact plate 9 attached is connected to the dust collection case 3, the pressure in the outer space of the dust exhaust port 6 and the space 18 formed by the front cover 7 and the front cover contact plate 9 are reduced. The pressure and the pressure inside the bag 20 fixedly attached to the dust exhaust port 6 with a fixed ring 19 are made to be equal. Reference numeral 21 denotes an outlet of the bypass passage 13, which opens toward the front cover 7 side of the dust collection case 3. Reference numeral 22 denotes a rod having a conical protrusion 22a formed at its tip and a spring body 23 attached to the other end for always biasing the rod 22 toward the main body 1 side. 22b is a spring receiving part formed at the end of the rod;
22c is a rod 22 that is more than a certain level than the bypass passage 13.
This is a protrusion formed to prevent the bypass passage 13 from falling out, and the protrusion receiver 13a of the bypass passage 13
It is formed to be able to slide freely inside.

Since the present invention has the above configuration, the bag 2
0 is attached to the dust exhaust port 6, a fixing ring 19 is attached to the outer periphery of the dust exhaust port 6 to fix the bag, and the front cover 7 is attached to the dust collection case 3 by operating the buckle 8. At this time, the outer peripheral edge of the bag 20 extends to the front surface of the dust collection case 3 and covers the front outlet 21 of the dust collection case 3 of the bypass passage 13. Further, the rod 22 provided in the bypass passage 13 is biased toward the main body 1 by a spring 23, and the conical protrusion 22a of the rod 22
is retracted from the end face of the front outlet 21, so the bag 20
Even if a finger is placed along the periphery of the outlet 21 during installation, the apex of the protrusion 22a will not injure the finger. Next, when the dust collection case 3 with the bag 20 and the front cover 7 attached is attached to the main body 1, the spring receiving part 22c of the rod 22
comes into contact with the main body 1 and presses the spring body 23 to release the rod body 22.
in order to push the bar 22 towards the front cover 7 side.
2a breaks the bag covering the front outlet 21 of the bypass passage 13 and releases the pressure in front of the electric blower 2, the bypass passage 13, the outer periphery of the dust outlet 6, and further through the ventilation hole 15 to the front cover 7 and the front cover backing plate 9. The pressures of the spaces 18 formed are the same vacuum pressure.
Therefore, the bag 20 is connected to the ventilation hole 16 of the front cover plate 9,
17 side, and does not stick to the filter 11, thereby preventing the vacuum cleaner function from deteriorating. Therefore, there is no need to fix the bag 20 to the dust collection case to prevent the bag 20 from adhering to the filter, or to install the bag 20 so as not to cover the bypass passage, which simplifies the operation of installing the bag 20 and makes it easy to use. sex has greatly improved.

As described above, according to the present invention, it is possible to provide a vacuum cleaner that can hygienically dispose of dust using a bag, prevent the bag from adhering to the filter, and at the same time fully demonstrate the function of the vacuum cleaner. This has the effect of improving usability.
