In Examples 5, 6 and 7, the suction of water and its contrivance are shown in FIGS.
As for the suction of water or the like, a small example of the present invention has been described in the fifth embodiment. However, if the length of the suction pipe (5) is 30 cm or more, the water level in the suction pipe (5) only rises by several cm. Therefore, when part of the air blowing from the blower is directed to the suction port of the suction pipe and sprayed, the water becomes droplets in the suction pipe (5) and is discharged from the outlet (2a) of the blow pipe. The configuration is shown in FIGS. 10 and 11. FIG. Furthermore, a pipe (14) inside the pipe for suction is provided to effectively take in water. The configuration is shown in FIGS.
Example 8 Example 9 describes an application of the present invention to a dust collector or vacuum cleaner. A simple example thereof is shown in FIGS.

A cylindrical blowout pipe (2) having a diameter of 9 cm and a length of 30 cm is provided, a cover (2b) is provided at the entrance (2d) of the blowout pipe (2), and an air blower outlet (1a) having an outer diameter of 32 mm and an inner diameter of 30 mm is provided. The lid (2b) is provided with a hole (2c) of 32 mm in diameter for receiving the pipe (3) connected to the outlet of the blower. A connection hole (4a) for connecting to a circular suction pipe with a diameter of 9 cm is provided on the side of the blowing pipe (2) near the lid (2b), and a suction pipe (5) with a diameter of 9 cm and a length of 50 cm is provided. to connect. The pet invention is 200g. The cross section of the pipe may be not only circular but also polygonal such as square, and it should be considered that it is easy to manufacture and has little air resistance. The blowing pipe (2) and the suction pipe (5) may be movable as shown in FIG. 5, as long as the suction efficiency is good. Further, the connecting portion (4) of the blowing pipe may be of a fitting type, a fitting rotary type, an integral type, or the like. 2 can be used as a blower, and if the net bag (7) is covered with the outlet (2a) of the blowing pipe as shown in FIG. Substitute.

FIG. 4 is an enlarged view of the hole (4a) for connecting the suction pipe (5) and the suction pipe (5). It is designed to prevent sucked dead leaves (8) and the like from clogging the connecting hole (4a). When the blowing force of the blower (1) is strong, the sucked air (6c) is also strong, and the connection hole (4a) can be enlarged to widen the size of the suction pipe and the suction port (5a) as a whole.

When it is desired to expose the blowout port (3a) to the front without removing the present invention from the blower (1), as shown in FIG. The lid (2b) is used as the inner cylinder (3b) so that (3) is the center of the cylinder, and the inner cylinder (3b) is slid to the outlet (2a) of the blowing pipe. When using the present invention, it can be used by pulling the inner cylinder (3b) to the inlet (2d) of the blowing pipe as shown in FIG. The suction pipe (5) may be made into a bellows and stored in a foldable manner.

In FIG. 8, when the pipe (1b) of the blower is thick enough to pass the dead leaves (8) sucked, the pipe (1b) of the blower is used as the blowing pipe (2), and the side of the pipe (1b) of the blower is shown. A drawing is shown in which a connection hole (4a) is provided in and a suction pipe (5) is attached. In this case, various measures such as opening and closing the connection hole (4a) and attaching/detaching the suction pipe (5) are required. As described above, the suction pipe (5) may be detachable, or may be made into a bellows and stored in a foldable manner.

FIG. 9 shows how the size of FIG. 1 of the present invention is reduced to 15 cm in length and 15 cm in width and 4 cm in height when sucking water. Water is sucked from the 4×4 cm suction port (5a) of the suction pipe by the blowing wind (6a), forms droplets in the pipe, and is discharged from the outlet (2a) of the blowing pipe. When a general-purpose household blower with an air volume of 3.5 m ³ /min and a weight of 1.7 kg is used, 500 cc of water (10) stored in the container (11) is discharged in about 20 seconds in the form of water droplets (10a).

The left side of FIG. 10 shows a suction pipe (5) with a cross section of 40 cm and the same length as the blowing pipe (2) having a square cross section of 9 cm on each side and having a length of 30 cm. In the middle of the pipe (3) connected to the blower outlet of the blower on the right side of FIG. 10, a distribution part (9) made of a cube with a side of 4 cm and dividing the air into two was provided. There are several ways to divide the wind (6a) ejected from the blower into two, such as making the pipe Y-shaped. A method of standing in the passing section was adopted. If the distribution plate (9a) is made movable with a fulcrum or of a telescoping type, the air volume can be adjusted, and either hole can be completely closed when distribution is not required.
In FIG. 10 and FIG. 11, a rectangular plate with a distribution plate (9a) extending from the corners of the distribution part (9) to the center was installed at an angle of 45 degrees with respect to the wind direction. Fig. 10 shows a separate mounting type, and in Fig. 11, the distribution part (9) is shown inside the dotted circle, and the pipe (12) for guiding the air to the suction port of the suction pipe (12) and the suction pipe (5) are integrated. 1 is a side view of a midline cross-section in body shape; FIG. In the distribution section (9), the distribution plate (9a) divides the wind into wind (9b) that changes direction and wind (9c) that does not change direction. In FIG. 10, the wind (9b) that changes direction passes through the pipe (12) that guides the wind to the suction port of the suction pipe with a cross section of 2 x 2 cm, reaches the lower edge of the suction pipe (5), reverses and turns to the suction port ( 5a), it becomes a wind (13a) that blows out in the suction port of the suction pipe in the direction of the connection hole (4). The wind (9c), which does not change its direction in the distribution part (9), is jetted from the outlet (3a) of the jetting pipe to the jetting pipe (2).

In FIG. 12, the lower end is the pipe that covers the suction port (13) in the suction pipe and the surrounding water intake (15), and the upper end is near the ejection port (3a) of the pipe (3) that joins the blower port. The internal suction pipe (14) is shown outside the suction pipe (5). FIG. 13 shows a side view of a mid-section of the suction pipe inner pipe (14) assembled into the suction pipe (5). In FIG. 13, the pipe (12) for guiding air to the suction port of the suction pipe is shown separated from the suction pipe (5). The wind (13a) ejected from the suction pipe inner spout (13) sucks water from the water intake (15), passes through the suction pipe inner pipe (14), and exits the suction pipe inner pipe outlet (14a). erupt.

FIG. 14 shows an example in which the present invention is applied to a cyclone type dust collector. A pipe (17) connecting the outlet (16a) of the cyclone type dust collector and the air intake (1c) of the blower is provided to circulate the air. The thickness of the connecting pipe (17) needs to be adjusted according to the force of the wind from the blower. If the wind pressure is strong, it is necessary to widen the outlet (16a) of the cyclone type dust collector.

When collecting dust with a paper pack, a filter, or a net (18), an exhaust pipe must be provided and suction must be performed with the connection pipe (17) of the air intake port of the blower in order to suck the dust behind the paper pack (18). In this case, dust is sucked by the suction pipe with the blowing air, so if it is applied to a canister-type vacuum cleaner, dust does not fly behind the vacuum cleaner.

Although the suction device that generates a suction force in the suction pipe by ejecting air from the blower to the blow pipe has been described above, the configuration and operation are not limited to those illustrated. It is well understood that many modifications and changes to the present invention are possible in view of the horsepower and shape of the blower, the size of the present invention, the thickness and arrangement of the pipes, the strength and materials of the present invention, the manufacturing cost, and the like. Therefore, all such modifications and alterations should be considered within the scope of the present invention.

It can be used as a suction device because it can suck things up with the pipe using the force of the wind blown by the blower. As an example, as described in Example 1, dead leaves can be blown off as a blower, and dead leaves can be easily sucked and collected by attaching a 200 g main unit and using a net bag. Also, it can be applied to a dust collector, an exhaust device, a vacuum cleaner, or the like.
