《Action》 Ash, which is a dust component in the butts sucked into the hose and mixed in the air flow, flows in a labyrinth along the guide plate, separates from the air flow at the discharge port, and is discharged into the dust pan. .

<< Embodiment >> An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, reference numeral 1 is a hand-held rectangular case having casters 2 and 3 provided at the bottom thereof, and a worker pushes a hand-pushing handle 4 provided at the rear portion of the case 1 so that the floor surface of the passage is raised. Moving.

A flexible hose 5 for suction is projected from the rear part of the case 1, and a worker holds a nozzle 6 provided at the tip thereof to bring the nozzle close to a butts holder attached to a pachinko machine, and the front side of the handle 4 of the case 1 The suction of the butts is performed by operating a switch provided on the operation panel formed on the surface.

Inside the case 1, the suction device 7 and this suction device 7
A separation device 9 having a discharge end connected to the base of the hose 5 through a duct 8 and a bottom made of a non-combustible material that is detachably and airtightly coupled to the lower part of the separation device 9. A cylindrical dust pan 10 is provided.

The suction device 7 includes a motor 11 and an exhaust blower device 12 connected to the output shaft of the motor 11,
The motor 11 is rotationally driven by using a battery 13 built in a lower portion thereof as a driving power source.

In response to this rotational power, the exhaust blower device 12 exhausts the air taken in from the upper side duct 8 side to the side part at a right angle,
The gas is discharged from an exhaust port (not shown) that is opened in the side portion of the case 1.

The dust pan 10 is supported on an installation plate 14 that is vertically guided below the dust pan 10.

The installation plate 14 is connected via a flat link 17 to a seesaw lever 16 which is integral with a pedal 15 protruding to the lower end of the rear portion of the case, and is raised in the lowered state of the pedal 15 shown by the solid line in the figure, and is held above it. The upper part of the dust pan 10 is airtightly coupled to the lower surface of the separating device 9, and is held in this state by a lock mechanism (not shown). Also, pedal 1
The installation plate 14 and the dust pan 10 are lowered by raising 5 as an imaginary line, and the dust pan 10 can be removed from the case 1 by opening the door provided on the rear surface of the case 1.

The separating device 9 has the structure shown in FIGS. 2 and 3.

In the figure, this separating device 9 has an outer cylinder 19 having a lower opening, in which a pipe 18 communicating with the hose 5 is projected to the outer periphery and a discharge port 19a communicating with the duct 8 is provided on the upper surface,
An inner cylinder 20 arranged substantially concentrically on the inner peripheral portion of the outer cylinder 19.
And a bottom plate 21 that covers the bottom surfaces of the inner and outer cylinders 19 and 20.

A flange 19b is formed on a lower peripheral edge of the outer cylinder 19 and is airtightly coupled to an upper opening peripheral edge of the dust pan 10 via a packing 22 fitted inside thereof.

The inner side of the pipe 18 is provided between the inner cylinder 19 and the outer cylinder 20, is introduced to the outside of a partition wall 23 forming a part of the inner cylinder 20, and an upper portion of a discharge port 24 opened to the bottom plate 21. Is connected to a coarse first filter element 25 made of a perforated plate.

In addition, the roughness of the filter element 25 is set to be at least smaller than the diameter of the cigarette.
The suction, which is the solid content of the butts introduced through 8, is fractionated by this filter element 25, and is dropped and accumulated through the outlet 24 into the dust pan 10 joined to the lower part thereof.

The air flow after the solid content is shaken off is introduced from the outer circumference of the inner cylinder 20 to the inside, so that the inside of the dust pan 10 is separated from the flow path of the air flow, and the inside of the dust pan 10 is airtightly joined to the separation device 9. The pressure is reduced. Therefore, even if an ember with a fire is taken into the dust pan 10, it will be extinguished spontaneously by decompression.

Further, since this solid content is separated from the flow path of the airflow, even if there is a fire, it will not spread.

A lower portion of the partition wall 23 opposite to the pipe 18 is notched, and the air flow swirls the peripheral edge of the inner cylinder 20 through the notch 23a, and the inner wall of the inner cylinder 20 is opened through an opening 26 formed in the upper outer periphery of the inner cylinder 20. Introduced to the perimeter.

And, a spiral shape is formed in the flow passage of the air flow, and a first guide plate 27 for guiding the air flow in the descending direction and a spiral shape are also formed on the upper end of the end of the first guide plate 27.
A second guide plate 28 for guiding the airflow in the rising direction is arranged.

A dust outlet 29 is formed in the lower surface of the bottom plate 21 at the lower end of the first guide plate 27.

As a result, dust such as ash that has not been filtered by the first filter element 25 descends along the first guide plate 27 in a state of being mixed in the air flow, and the first guide plate 27
When the air flow turns back and rises at the terminal end of the air flow, the air flow becomes a spiral shape, is separated from the air flow, and is dropped and accumulated in the dust pan 10 through the discharge port 29. The airflow from which the dust has been shaken up rises along the second guide plate 28, is turned upside down at the end of the second guide plate 28, and is reversed and introduced into the inner circumference of the inner cylinder 20 through the opening 26.

Even during this reversal, the dust falls on the first guide plate 27 due to the vortex state of the air flow and is guided to the discharge port 29.

A fine second filter element 30 is housed in the inner circumference of the inner cylinder 20, and upper and lower end plates 30a thereof are provided around the top discharge port 19a of the outer cylinder 19 and the bottom plate 21.
It is airtightly sandwiched between the inner bottom surfaces of the.

Therefore, the airflow introduced into the inner circumference of the inner cylinder 20 permeates from the outer circumference to the inner circumference of the second filter element 30, and the fine particle components such as fine dust and smoke contained in the airflow are filtered and discharged there. It is discharged to the side of the case 1 through the outlet 19a, the duct 8 and the exhaust blower device 12.

A lid 31 that can be opened and closed is provided on the lower surface of the bottom plate 21 inside the inner cylinder 20 so that the lid 31 can be replaced when the filtering capacity of the filter element 30 is reduced.

<Effect> As described in detail with reference to the embodiments above, in the present invention, dust such as ash mixed in the air flow sucked into the hose flows in a labyrinth along the guide plate and is discharged. At that point, it is separated from the air flow and discharged into the dust pan.

Therefore, in this invention, since the dust is separated before reaching the filter element, the filter is not clogged early with the dust, the flow resistance is not increased, and even fine particles such as smoke can be removed. It is possible to achieve the practical application of a kind of vacuum cleaner for cigarette butts.
