[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a backpack-type vacuum cleaner mainly used for cleaning work in stations, underground malls, building passages, roads, etc., and is characterized by being excellent in workability regardless of location.

[0002]

[Prior art]

 Conventionally, when cleaning a station, an underground mall, a building passageway, or a road, an operator generally has a collection pipe, and a traveling wheel is attached to a main body composed of a motor, a suction blower, a garbage storage tank, etc. The provided vacuum cleaner is used.

A power cord for driving the motor is connected to the main body of the vacuum cleaner.

[0004]

[Problems to be solved by the device]

 Since the power cord is connected to the main body of the conventional vacuum cleaner, the length of the power cord is the limit of the cleaning work range when cleaning a building passage, a road or the like.

Therefore, the power cord is replaced, and the collection tube connected to the main body is made long to extend the working range. However, it takes time to handle the power cord. Moreover, when the collection tube is made long, there is a problem that the suction performance deteriorates.

[0006] In a place with more steps, for example, when cleaning the stairs of a station, or the spectator seats of a theater, a stadium, etc., the main body cannot be freely moved, and the cleaning work is extremely difficult. There is a problem that it takes time and that the power cord is entangled.

The present invention has been made in view of the above circumstances, and can be used in any place, has excellent workability, and further, the amount of collected dust can be visually confirmed for efficient waste treatment. The purpose is to provide a backpack-type vacuum cleaner that can be used.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a waste container having a lid provided with a suction part, a motor, an exhaust fan, a filter surrounding the exhaust fan, and an exhaust hole on an upper stage of a two-stage backpack mount. It is detachably mounted, and the battery for driving the motor is detachably mounted in the lower stage. Furthermore, the dust container is made of a transparent or translucent material. A smoke detector is installed at an appropriate position in the passage.

[0009]

[Action]

 Since the backpack vacuum cleaner of the present invention uses a battery as a power source, it does not require a power cord like conventional vacuum cleaners, and since it is a backpack, it can be used anywhere regardless of work. It has excellent properties. Furthermore, if the configuration is such that the amount of collected dust can be easily confirmed from the outside, swift dust disposal is possible and extremely efficient cleaning work can be performed.

The backpack-type vacuum cleaner of the present invention is carried by an operator and holds the collecting tube 17 for cleaning work. When the power switch 16 provided in the collection tube 17 is turned on and the motor 8 provided in the lid 6 is driven, the exhaust fan 9 is rotated by the motor 8 and the air in the dust container 2 is exhausted. After being discharged from the hole 13, the inside of the dust container 2 becomes negative pressure.

As a result, air and dust are sucked from the nozzle 18 of the collection pipe 17 into the dust container 2 via the flexible hose 15 and the suction portion 7.

Then, of the air and dust sucked into the dust container 2, only air passes through the cloth filter 12 and the paper filter 11 and is discharged to the outside of the dust container 2 from the exhaust hole 13 of the lid 6. Then, only the dust that does not pass through the cloth filter 12 and the paper filter 11 is left in the dust container 2.

If the dust container 2 is made of a transparent or translucent material, the amount of dust trapped in the dust container 2 can be visually confirmed from the outside as described above, which is convenient.

In the present invention, in the cleaning work, the suction unit 7 and the exhaust hole 13 are provided in the lid 6 of the dust container 2 in the present invention. Therefore, when the lid 6 is removed, the dust container 2 becomes a complete container, and the dust treatment after removing it from the backpack mount 1 is extremely easy. At the same time, the exhaust air during the cleaning work is directed upwards and is not diffused to the worker and the surroundings.

Further, since the backpack mount 1 has a two-stage structure and a heavy battery is detachably mounted on the lower stage thereof, a sense of stability can be obtained and workability is enhanced even when the backpack is carried.

Furthermore, if a smoke detector is provided at an appropriate position in the intake / exhaust passage, it is safe even if a cigarette or the like is forgotten and smoked.
