Further, between the hollow tubular collar upper portion 107 and the hollow tubular collar lower portion 108, there is a stepped portion 107a having a stepped shape that fills the diameter difference.

A tubular connecting pipe portion 105a in the connecting pipe 105 is arranged inside the collar lower portion 108. The diameter of the collar lower portion 108 has a diameter sufficient for the tubular connecting pipe portion 105a in the connecting pipe 105 to be slidably arranged, and has a slight clearance with respect to the diameter of the tubular connecting pipe portion 105a in the connecting pipe 105. have. Further, as described above, although the collar upper portion 107 has a larger diameter than the collar lower portion 108, it can accommodate the coil spring 109 arranged so as to be wound around the connection pipe portion 105a arranged inside the collar upper portion 107. It has a sufficient diameter.

One end of the coil spring 109 is in contact with the stepped portion 107a having a stepped shape between the collar upper portion 107 and the collar lower portion 108, and the other end is arranged so as to be in contact with the switching plate 110. As a result, the switching plate 110 is pressed in the direction in contact with the first wall portion 102 by the elastic force of the coil spring 109. As a result, the connection pipe portion 105a in the connection pipe 105 and the solid pipe 70 or the liquid pipe 80 connected to the switching portion 100 are connected at the will of the user. This will be described further later.

The connecting pipe 105 is pulled in the direction of the second wall portion 103 so as to oppose the elastic force of the coil spring 109. As a result, the connection between the solid pipe 70 or the liquid pipe 80 connected to the switching portion 100 and the connecting pipe 105 is released. After that, by sliding the switching plate 110 in the left-right direction, the liquid pipe 80 or the solid pipe 70 is connected to the connecting pipe portion 105a in the connecting pipe 105.

The cleaner 10 of this embodiment can be arranged on the trolley 200. The dolly 200 has a loading platform 201, a handle 202, front casters 203 and 203, and rear casters 204 and 204.

The diameter of the wheels of the front casters 203 and 203 is preferably 100 mm. Further, the rear casters 204 and 204 are casters fixed in the forward direction, and the diameter of the wheels thereof is preferably 150 mm. This is because it is suitable for traveling in a place where the ground is not leveled and can prevent a fall.

A method of using the cleaner 10 having the above configuration will be described. A user (not shown) determines whether the object to be aspirated is a solid or a liquid. A case where the object to be sucked is a solid and the liquid pipe 80 and the connecting pipe 105 are connected in advance will be described (see FIG. 5).

A user (not shown) pulls the connecting pipe 105 toward the second wall portion 103 so as to oppose the elastic force of the coil spring 109. As a result, the connection between the liquid pipe 80 and the connection pipe portion 105a in the connection pipe 105 is released (see FIG. 7). Further, a user (not shown) moves the connecting pipe 105 along the elongated hole 104 in the second wall portion 103. The length of the major axis in the horizontally long hole 104 is the amount of movement of the connecting pipe 105, which coincides with the distance between the solid pipe 70 and the liquid pipe 80. Therefore, the connecting pipe 105 can be moved from the other end of the major axis in the elongated hole 104 to one end (see FIG. 8).

By moving the connecting pipe 105 from the other end of the major axis in the elongated hole 104 to one end in this way, the switching plate 110 to which the connecting pipe 105 is connected also moves. The switching plate 110 is close to the other side wall portion 101b of the switching box portion 101 having a horizontally long rectangular parallelepiped shape, and the connecting pipe 105 moves to a position facing the solid pipe 70. After that, the connecting pipe portion 105a in the connecting pipe 10 pulled in the direction of the second wall portion 103 is restored according to the contraction force of the coil spring 109 so as to counter the elastic force of the coil spring 109, thereby causing the connecting pipe 105. The connection pipe portion 105a in the above and the solid pipe 70 are connected. Since the liquid pipe 80 is blocked by the switching plate 110, the air flow is not sucked from the liquid pipe 80.

After that, the user turns on a switch (not shown), exerts the suction force of the suction unit 20, and sucks the solid from the suction hose 160 connected to the connection pipe 105. This solid is stored in the solid storage unit 30 from the lower cover 22 in the suction unit 20 via the connecting pipe 105, the switching unit 100, and the solid pipe 70 by the suction force of the suction unit 20. (See FIG. 9B, arrow X). The air flow is discharged to the outside through the discharge hole 21a in the suction unit 20.

On the other hand, since the liquid pipe 80 is closed by the switching plate 110, the suction force of the suction unit 20 can be exerted to suck the solid by the solid suction pipe 70 (see FIG. 8).

Next, a case where the object to be sucked is a liquid and the solid pipe 70 and the connecting pipe portion 105a in the connecting pipe 105 are connected in advance will be described.

A user (not shown) pulls the connecting pipe 105 toward the second wall portion 103 so as to oppose the elastic force of the coil spring 109. As a result, the connection between the solid pipe 70 and the connecting pipe portion 105a in the connecting pipe 105 is released. Further, a user (not shown) moves the connecting pipe 105 along the elongated hole 104 in the second wall portion 103. The length of the major axis in the horizontally long hole 104 is the amount of movement of the connecting pipe 105, which coincides with the distance between the solid pipe 70 and the liquid pipe 80. Therefore, the connecting pipe 105 can be moved from one end to the other end of the major axis in the elongated hole 104 (see FIG. 5).

By moving the connecting pipe 105 from one end to the other end of the major axis in the elongated hole 104 in this way, the switching plate 110 to which the connecting pipe 105 is connected also moves. The switching plate 110 is close to the side wall portion 101a of the switching box portion 101 having a horizontally long rectangular parallelepiped shape, and the connecting pipe 105 moves to a position facing the liquid pipe 80. After that, the connecting pipe portion 105a in the connecting pipe 10 pulled in the direction of the second wall portion 103 is restored according to the contraction force of the coil spring 109 so as to counter the elastic force of the coil spring 109, thereby causing the connecting pipe. The connection pipe portion 105a in 105 and the liquid pipe 80 are connected. Since the solid pipe 70 is blocked by the switching plate 110, the air flow is not sucked from the solid pipe 70.

After that, the user turns on a switch (not shown) to exert the suction force of the suction unit 20. The suction force sucks the liquid from the suction hose 160. This liquid is stored in the tank portion 41 of the liquid storage portion 40 via the suction hose 160, the connecting pipe 105, the switching portion 100, and the liquid pipe 80 by the suction force of the suction portion 20. (See FIGS. 10A, B, arrow Y). Further, the sucked airflow flows from the upper part 42 of the tank in the liquid storage part 40 through the liquid suction pipe 85 (see FIGS. 11A, B, and arrow Z) into the lower cover 22 in the suction part 20, and is discharged to the outside through the discharge hole 21a. To.

On the other hand, since the solid pipe 70 is closed by the switching plate 110, the suction force of the suction unit 20 can be exerted to suck the liquid by the liquid pipe 80.

As described above, the float 401 is built in the tank upper portion 42 in the liquid storage unit 40, and the stopper 403 connected to the float 401 by the connecting rod 402 rises as the float 401 rises. It has a super stop mechanical mechanism 400 that stops overflow at the time of liquid suction by closing the inlet of the liquid suction pipe 85. Further, the suction wind M containing the mist in which the liquid is almost removed from the sucked liquid (see the arrow Y in FIG. 12) but the fine liquid is scattered is in the shape of a slit arranged so as to surround the float pipe 404. By invading the slit 410 having a gap between the two, the mist is collected and becomes a liquid from the splash, so that the invasion of the liquid is prevented from the liquid suction pipe 85. Therefore, the suction air (arrow Z) containing almost no mist is sucked into the liquid suction pipe 85. Therefore, it is possible to prevent the mist from entering the suction unit 20 through the liquid suction pipe 85 (see FIG. 12).

In this way, the liquid is stored in the liquid storage unit 40 and the solid is stored in the solid storage unit 30 by identifying the target to be sucked by the user (not shown) in advance. Separation becomes extremely easy, and it may be possible to reuse the liquid or solid. As a result, the recycling rate of resources can be increased, waste can be reduced, and disposal costs can be recovered. In addition, the amount of sludge and sewage washed can be reduced, and the labor and time for drying and separation work can be reduced.
