Abstract

PROBLEM TO BE SOLVED: To perform a comfortable cleaning free from clogging without sucking small stones to a narrow diameter part by providing a protecting wall for receiving the water flow of a suction part major diameter part with a shape curvature close to a right angle so as to suck light dust by specific gravity difference. SOLUTION: The rear wall 3 of a major diameter part 1 is set substantially vertical to a side inner wall 7 and a bottom inner wall 8. Thus, small stones 9 carried by a water flow 6 are collided with the rear wall 3, and never physically carried to a narrow diameter part 10. This effect is enhanced by a height 11. Since a room wider in the rear than in the front is formed, the water flow is weakened, and only the dust having a light specific gravity is sucked by a sucking narrow diameter part 5. The substantially right-angled rear wall 3 and the size of a large racemes chamber 12 produce a synergistic effect, and stones are never sucked to the narrow diameter part 10. The stones collected on the bottom inner wall 8 is vertically vibrated (shaken), and the high rear wall is useful to further float the dust. Since a suction port 2 has wide frontage, stones are never clogged in the top end as in a conventional one having a small hole.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cleaning of aquariums, ponds, etc. in live fish rearing and breeding of aquatic plants. More specifically, the present invention uses pressure or the like to reduce clogs such as pebbles or the like with narrow through holes. Considering the physical principle so that it does not reach, and adopting a nearly right-angled sharp curve that makes it difficult for pebbles etc. to enter the large diameter part of the aspirator, so that pebbles etc. of the aquarium and pond do not enter the cleaning equipment narrow tube part. Cleaning efficiency.

[0002]

2. Description of the Related Art A large diameter suction port is used for pebbles using the difference in the specific gravity of garbage. Pebbles and the like also entered the small diameter portion, and the efficiency was not improved due to clogging.

[0003]

In order to prevent pebbles from entering, if only a large diameter is used, the specific gravity difference between dust and pebbles cannot be fully utilized, and pebbles will also enter the small diameter portion of the joint and become clogged. . It is necessary to prevent clogging where stones do not enter.

[0004]

SUMMARY OF THE INVENTION In view of the conventional drawbacks, the inventor of the present invention has provided a protection wall for receiving a water flow near a right angle, that is, a sharp curve, at a large diameter of a suction portion, and while absorbing light debris with a specific gravity difference, pebbles and the like. The internal form that does not suck up to the small diameter part was adopted. This is called the back wall (meaning the wall behind the water flow).

[0005]

FIG. 1 shows a first embodiment. (A) Left side view, (b) Plan view, (c) Left side view turned upside down. The inner wall is indicated by a dotted line in the description. The rear wall 3 of the large diameter portion 1 is set substantially perpendicular to the side wall 7 and the bottom wall 8. As a result, the pebbles 9 carried by the water flow 6 that has naturally entered the rear wall 3 at a substantially right angle do not physically go to the small-diameter portion 10. There is a height 11 and the effect increases. Since the room is wider at the back than at the front, the water flow is weakened and only light trash can be sucked well. The approximate right angle and the size of the room create a synergistic effect, and no stones are sucked up to 10. In addition, the stones that have accumulated on the inner wall of the bottom surface vibrate up and down (shake), and the height of the rear wall is useful to further lift the dust. Since the suction port 2 is wide, the stone does not get clogged at the forefront unlike the conventional one having a small hole. FIG. 7C shows that the design is such that the stones or the like in the room can easily come out by turning the stone upside down.

[Description of the conventional one]

FIG. 3 shows a conventional one. Since the diameters (13, 14) are the same from the suction port 2 to the rear wall 3, the water flow is constant despite the large-diameter portion 1, and the pebbles 9 are carried to the small-diameter portion 10, which is often inconvenient. Was. Also
The reason was that there was no stagnation due to the constant water flow, and the rear wall 3 with respect to the entrance 2 was a gentle curve, so that it was physically easy to reach the small diameter portion 10. Here (1
At 0), the inefficiency was strongly felt. A sufficient maximum diameter part, that is, a chamber that creates stagnation of water should be provided between the entrance and the small diameter part 10. Back wall 3
Should be substantially perpendicular to the inner side wall 7. Had such disadvantages. Also, there was no way to shake up and down to make only the garbage float. It is not shaking up and down.

[0007]

FIG. 2 shows a second embodiment. The pebbles that have entered the bunch (room formed by constriction) 12 can be immediately removed by turning them upside down as in the first embodiment, so that they are omitted. The constriction (recess) 17 may be a flat surface. In the following embodiment, 17 may or may not be provided. Although the embodiment is omitted by way of example only, it is assumed that the present invention is included in the present invention regardless of whether 17 is provided or not. It can be said that the effect of the constriction (recess) 16 is sufficient. In each of the examples, the left side surface is centered. The inner wall is represented by a dotted line. In the second embodiment shown in FIG.
Since (c) and (d) are the same, a plan view is omitted. A feature of the second embodiment is that two or more walls 3, 18, 19, 20, 21 are received in a state almost perpendicular to the water flow. Other advantages are the same as those described in the first embodiment, and a description thereof will not be repeated. Another major feature of the second embodiment is that there are a plurality of large atrioventricular chambers 12. As a result, there is very little pebbles going to the smaller diameter portion 10. The number of rear walls increases and the protection of incoming pebbles becomes more complete. Arrows indicate that the pebbles moved by the water flow fall down on the rear wall (3, 18, 19, 20, 21) and do not reach the small diameter portion 10. Thus, pebbles that once lost momentum due to the installation of the rear wall will fall down, but if there is no rear wall, the pebbles that have gained momentum will go to 10 except for the other, and they will be clogged. In both the first embodiment and the second embodiment, a hose joint or a hose is connected to the attachment portion 4 to suck and discharge dust using a motor, pressure (siphon) or the like.
In addition, the rear wall which receives and removes the pebbles is formed by a constriction, and the one which is formed as a protrusion and whose outer surface is not constricted is also included in the present patent.

[0008]

FIG. 4 shows a third embodiment. (A) is a side view, (b)
Is a plan view. The inner wall is represented by a dotted line. As shown in the first and second embodiments (several patterns), the rear wall (2
4, 25, 26), the stone (9) hitting the rear wall goes outside and falls down. Mogami Room 12
Going to is a configuration in which only light, garbage is collected. The angle of the rear wall is set so that the stone that goes up can easily return to the bottom. (Arrow 27) In all of the first to third embodiments, the energy of the discharge is obtained from the motor, pressure and siphon by connecting to the joint.

[0009]

Fourth Embodiment FIG. 5 shows a fourth embodiment. Suction port (2)
Four pillars were installed around. This suction port is 31. These four suction ports (31) are still wide enough and have a frontage that does not cause 10 clogging.
Many conventional products have many small holes in the bottom surface 28, and the small holes are quickly blocked by small stones 9 due to water suction or pressing force when cleaning the bottom of the water tank. However, if the size of the suction port (31) is large, the stone will not be jammed. Other things first
Since the third embodiment has already been described, the description is omitted. The feature is a spherical shape at the tip (meaning that the shape is round, but not limited to a sphere). The projection (30) has a small amount of snagging, etc. and is safe without breaking such as a net laid under a stone. . The protrusions (30) are used to stir the stones, and to help light dust to be sucked from the suction port 28 at the same time as the start of work.

[0010]

FIG. 6 is a left side view of the fifth embodiment.
(A) is a bottom view thereof. (C) is a diagram illustrating a method of taking out a stone (a stone that has not been reached to the drainage small-diameter portion 10) in the back. (D) is a cross-sectional view of the cross-section 39 viewed from the direction of the arrow 40. In FIG.
It represents. The central part has a large diameter to weaken the water flow and stabilize the water, so that only the light garbage (a) 38 is brought into the small-diameter pipe 10 so that pebbles are not allowed to go to this part. The third, fourth, and sixth embodiments may also employ this method. Each embodiment has been described by way of example only, and those having advantages apply to other embodiments. The rear wall of the present embodiment that protects pebbles at a substantially right angle or at an angle larger than that is described in this embodiment as, for example,
Regarding the rear wall 33, a cross section of this portion (a cross section of the 39 cross section as viewed from the arrow 40) is shown in FIG. This rear wall 33 (the rear wall is called the wall behind the water flow)
The heavy stone rolls down, so stop it at this wall to keep it from going to the small diameter pipe (10). In the past, stones often clogged this area and made cleaning impossible. Light garbage floats and passes through the upper half (A) 10 (D) 41. In Figure (a), it can be seen that the bottom of the cleaning tool is flat to make it easier to slide the bottom of the tank. This device has a streamlined shape and can be used for gravel.
The spherical projection 30 at the tip is effective for breaking up the gravel. A large amount of gravel enters through the suction port 2, but the first rear wall 33
Stop at.

At this time, if there is no wall, a considerable amount of water flows to the narrow tube entrance 10 by the force of the water flow 6, which causes clogging. Even if a small stone 9 breaks through this part, the force is weakened even if a small stone 9 pierces this rear wall 33, so that the stone 9 rolls on the opposite surface of the wall 33 and falls into the through hole 42 to the outside to go out. At this time, the device is slipping on the bottom of the aquarium, so the energy sucked into it is not working here. So you can get out. The declining stone goes down by gravity. Even if a fairly light stone goes to the rear wall 34, this part can be completely protected by the rear wall 34 because the chamber 12 is wide and the water flow is not strong, so either go out of the hole 42 or enter the hollow here. Stand still. Later, if time passes, it may be taken out of the hole 42. Lift up the back (c)
When sucking out all the pebbles in the instrument as in the above, the suction water flow is strong and even if a light stone goes to the rear wall 36 at the rear end, it will hit the rear wall 35 and fall down. Eventually I can get out of 2,42. The movement of such a stone is being prototyped using a transparent container, and is being studied. If you devise many steps in this way, it is unlikely that you can easily go to 10 parts as in the conventional type (Fig. 3). The effectiveness of this ingenuity is great. The arrow 43 at the rear of FIG.
It indicates that the user can move up and down freely during operation.

The amount of stone in the instrument can be determined from the movement of the dirty water (near the suction port 2). If there is a lot of stone inside, it will be harder to suck in the garbage outside. If the suction becomes worse, the movement 43 may be performed. Discharge as shown in (c). With such a mechanism, only dirty dust (see FIG. 38) can be sent to the thin pipe portion 10. Most of the above description is common to the first to fourth embodiments. Each embodiment shows an example, and the above may be applied. Many of these aquarium and pond cleaning tools have been developed based on simple ideas in the past, and many of them lack research. Fig. 13 (a) shows that the joint is inserted into the thin pipe section 4. The suction energy following this is currently excellent, but the essential suction section is currently in trouble. It's not an exaggeration to go,
This is the invention. The number of back walls is not limited.
This should be considered depending on whether the tank is a large tank (large pond) or a small tank. What is important is that the water flows at a substantially right angle to the bottom inner wall and the side inner wall.

[0013]

FIG. 7 shows a sixth embodiment. In the second embodiment [FIG. 2] and the third embodiment [FIG. 4], this term is used to mean that the rear wall is located behind the water flow. The wall that catches the pebbles and the like that enters the final thin pipe section 10 to prevent clogging by clogging) is a constriction (16 in FIG. 4).
And no constriction like the first embodiment (FIG. 1), the fourth embodiment (FIG. 5), the fifth embodiment (FIG. 6), and the sixth embodiment (FIG. 7). However, each embodiment shows an example, and the absence of constriction is not an important part of the present invention. The important thing is that there is a back wall. In the case of the first, fourth, fifth and sixth embodiments, there is no constriction as shown in FIGS. If there is no constriction, FIGS. 1, 5, 6, and 7 show a racket-shaped rear wall (the rear wall can be brought to the center of the suction chamber by a support 47 as shown at 44 in FIG. 7). It is an effective wall, as can be seen in the description of the way the stone flows in 7. The water flow naturally has an orientation to the arrow (50), but the wall there is very effective, ie the rear wall 44 The next wall 45 protects the outside even if it shifts left and right, and the rear wall used in each of the eighth and sixth embodiments is compatible. 7A, which is not limited by the embodiment, is a plan sectional view formed by the sectional designating line 48. A donut-shaped rear wall is shown. When this wall 44 is provided, the stone off this center is the next wall 4
5 and so on. In other words, it is possible to receive in a zigzag manner. Considering the water flow and further studying, it should be possible to clean the stones and the like that do not go to the small-diameter portion entrance (10) at all.

Although various methods have been adopted from the first embodiment to the sixth embodiment, it is very difficult to suck and discharge only dust as described above, and pebbles are immediately sucked into the hose joint portion which is a thin tube. The work is interrupted due to blindness. To put it simply, it might be a good idea to provide a small hole or the like at the tip of the suction unit, but this does not work at all. It's something that you can finally realize after keeping fish for decades. In the stoma, stones of the same diameter are immediately inserted into the stoma and completely clogged. In contrast, the presence of the rear wall (partition wall) as in the present invention caused sufficient stagnation of the water, and almost no stones or the like reached the capillary.

[0015]

According to the effect of the large-diameter portion, the rear wall receiving the water flow, which has increased the rear diameter and changed the stagnation of the water flow, has been set to a state close to a right angle or more. A rear wall (partition) was installed to conveniently reduce the water flow. As a result, the pebbles harmful to fish (sludge) can be discharged out of the water tank and the pond comfortably without bringing the pebbles close to the small diameter portion 10.
Everyone easily thinks that if a net or a small hole is made at the tip of the suction port, pebbles will not enter, but this is not the case. This can only be realized after decades of fish breeding. In view of this, the present invention was born. The effect can be said to be sufficient. The idea of the back wall, which gives a stagnation to the water flow, eliminates only trash, and pebbles etc. can be cleaned without clogging and comfortable without being sucked into a thin part such as a hose.
