Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aquarium cleaner equipped with an electric suction pump that can easily clean dirt on the surface, underwater, or bottom of an aquarium.

Conventional aquarium cleaners are already known, such as a water surface cleaner that can only clean the water surface and a water bottom cleaner that can only clean the water bottom. Not proposed yet.

A conventional water surface cleaning device is explained using Fig. 1.
In the figure, 1 is the body of the water surface cleaner, 2 is the body 1
3 is a motor; 4 is a switch for operating the motor drive attached to the upper outer surface of the body 1; 5 is a rubber coupler connected to the output shaft of the motor 3; 6 is the driving force of the motor 3. A transmission shaft 7 is a screw fixed to the lower end of the transmission shaft 6. Reference numeral 8 denotes a filter made of a wire mesh or the like fixed slightly above the screw 7 in the body 1. The transmission shaft 6 passes through this filter 8, and the penetrating portion also serves as a bearing for the transmission shaft 6. 9
is a liquid inlet formed in the middle part of the body 1,
A liquid level line (not shown) is marked on the outer periphery of the body at the same height as the inlet 9 by an appropriate method. Reference numeral 10 denotes a liquid discharge port formed in four directions around the outer circumference at the same height as the screw 7 at the lower part of the body 1, and 11 is a lid fitted into the lower part of the body 1.

The function of this conventional water surface cleaning device is as follows:
When turned ON, the motor 3 is rotated by the dry battery 2, and the screw 7 is connected via the rubber coupler 5 and the transmission shaft 6.
rotates. Now, hold the body 1 by hand and insert it from the bottom of the body to a place other than the water surface A, and when the liquid level line marked on the outer circumference of the body 1 matches the water surface A, the water on the water surface will flow into the body 1. It is discharged from the discharge port 10 by the screw 7, and at this time, the garbage floating on the water surface A flows in with the water and is captured by the filter 8. Thus, the garbage floating on the water surface is collected at the upper part of the filter 8 in the body 1. That will happen.

However, this conventional water surface cleaning device cannot collect garbage underwater or especially on the bottom of the water, and in addition,
Even in the case of water surface cleaning, there are the following drawbacks. That is, since the lid 11 is attached to the lower part of the body to safely protect the screw 7, the outlet 10 is provided in the lateral direction of the screw part of the body, so the water flow is bent at right angles and does not flow smoothly. It is inefficient or inefficient, and the outlet is quite close to the water surface A (because it is for cleaning the water surface,
(It is not a good idea to make the body unnecessarily long), a path is created in which the discharged water returns to the inlet 9 and circulates, and furthermore, this discharged water pushes back the garbage that tries to enter the inlet 9. , the garbage collection function is low, the area of the filter 8 is small, so the mesh must be made large to reduce water resistance, so fine garbage can pass through, and the switch cannot be turned off after garbage collection. When the motor 3 is turned off and the rotation of the motor 3 is stopped, the garbage collected on the upper part of the filter 8 floats up and comes out of the mesh body 1 through the inlet 9. This method was not completely satisfactory due to drawbacks such as the fact that the body 1 had to be raised above the water surface while trying not to float up.

In addition, Fig. 2 shows a conventional bottom cleaning device, and in the figure, 12 is a power supply chamber at the top of the cleaning device;
3 is a dry battery, 14 is a motor, 15 is a switch, 1
6 is a connecting cylinder, 17 is a rubber coupler, 18 is a transmission shaft, 19 is a suction pipe/pump chamber fixed to the lower part of the connecting cylinder 16, 20 is a vane fixed to the lower end of the transmission shaft 18, and 21 is a suction pipe 19. Inlet at lower end, 22
2 is a connecting pipe connected to the side of the blade 20, 23 is a filter chamber attached to the connecting pipe 22, and 24 is a connecting pipe 2 for collecting dirt and water that have flowed into the filter chamber
2 is a check valve that prevents backflow to the blade 20 side through 2, 25 is cotton packed in the filter chamber 23 to capture garbage, and 26 is a discharge port for discharging water after the garbage has been removed. It is.

This conventional water bottom cleaning device connects the suction port 21 to the water bottom B.
When the motor 14 is rotated while the blade 20 rotates, the water containing dirt sucked in from the suction port 21 is sent to the filter chamber 23 via the connecting pipe 22, and the waste is collected by the cotton 25. , the remaining water is discharged from the outlet 26. After cleaning the bottom of the water, the switch 15 is turned OFF and the cleaner is taken out of the water, but at this time, the water in the filter chamber 23 is still prevented from flowing back by the check valve 24.
Therefore, the dust inside the filter chamber 23 can be removed and cleaned after the cleaner is taken out.

This conventional bottom cleaning device is suitable for cleaning debris on the bottom of the water, and there is no particular problem in its use.
It is not possible to clean debris on the water surface.

The present invention combines the functions of the conventional water surface cleaner and bottom cleaner described above, and
An object of the present invention is to provide an aquarium cleaner which is capable of cleaning both underwater and the bottom of the water, and which eliminates all of the above-mentioned drawbacks of conventional water surface cleaners.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 3 and 4, the power supply chamber 12, the connecting tube 16, and the components housed therein are almost the same as those of the conventional bottom cleaner shown in FIG. The same reference numerals are used to omit the explanation. In the figure, 27 is a pump chamber, 2
Reference numeral 8 denotes a bearing member that connects the connecting cylinder 16 and the pump chamber 27. The bearing member 28 itself is fixed to the outer periphery of the lower end of the connecting cylinder 16, and is detachably fixed to the pump chamber 27 by screwing. Furthermore, it has a bearing part 28a that supports the transmission shaft 18, and this bearing part 28a is arranged as close to the blade 20 as possible to prevent the transmission shaft 18 from bending. 29 is a suction pipe having a suction port 30 at its tip, which is connected to the pump chamber 2.
7, and is rotatably attached to the suction port 3.
It can be rotated and fixed at any position between the upward position C where 0 is at the top and the downward position D where the suction port 30 is at the bottom, and the fitting portion between the suction pipe 29 and the pump chamber 27 is, for example, A watertight structure is achieved by fitting the ring-shaped recess on the pump chamber 27 side and the ring-shaped protrusion on the suction pipe 29 side.

31 is a check valve provided on the opposite side of the suction pipe 29 attachment part of the pump chamber 27; 32 is the pump chamber 27;
The filter is detachably fixed to the filter, and is formed by integrating a net material 32a and a frame 32b. Further, reference numeral 33 is an adjustment collar slidably and fixedly attached to the outer periphery of the connecting cylinder 16, and is used to adjust the position of the suction port 30 of the suction pipe 29 from the water surface A.

Next, to explain the operation of the aquarium cleaner, first, when cleaning the water surface, as shown in FIG.
The pump chamber 27 is immersed in water, and the suction port 3 is
Hold the entire cleaner so that 0 matches the water surface A. At this time, for example, pass two plates over the water tank, and on the other hand, slide and fix the adjusting collar 33 at an appropriate position along the outer periphery of the connecting tube 16, so that the suction port 30 is at the water surface A.
The cleaner may be held by placing the adjusting collar 33 on a plate in a state that matches the above.

When the switch 15 is turned on, the motor 14 and therefore the blades 20 rotate, and the water in the pump chamber 27 is discharged through the check valve 31 and the filter 32. This drainage by the vanes 20 creates a head between the pump chamber 27 and the water surface A, and the water at the water surface A flows into the suction pipe 29.
It flows into the pump chamber 27 like a waterfall, but
In this case, if the water surface A is at an appropriate position in the suction port 30, the amount of inflow water and the amount of drainage will be balanced, and the water will sequentially flow in and be drained. Also at this time, feather 2
0 discharges air along with water, so the filter 32
Air bubbles E come out through it. The optimal position for the suction port 30 is a position where the maximum amount of surface water on the water surface A flows in.
Debris floating on the water surface A is sucked into the pump chamber 27 through the suction port 30 along with the inflow water, captured by the filter 32, and collected inside the filter 32 of the pump chamber 27. In addition, since the direction of inflow water entering and the direction of discharge water exiting are in one direction,
A constant flow occurs in the surface water in the aquarium, and debris on the surface of the aquarium naturally collects at the suction port 30.

Next, in the case of cleaning the bottom of the water, as shown in Fig. 6, turn the suction pipe 29 downward so that the suction port 30 is facing downward, and touch the tip of the suction port 30 to the bottom of the water or move it slightly away from the bottom. Motor 14 and blades 20
When rotated, water flow as shown in the figure is generated, and debris on the bottom of the water is similarly collected. At this time, the discharged water does not directly hit the garbage that has settled on the bottom of the water, so
It does not stir up debris and is easy to clean.

When cleaning dirt at a desired depth in the aquarium, the direction of the suction pipe 29 may be adjusted so that the suction port 30 is located at the desired depth. At this time, if necessary, the position of the adjustment collar 33 is also adjusted.

After collecting the garbage, turn on switch 15.
If you turn off the motor 14 and lift the cleaning device above the water surface, the water and dirt between the filter 32 and the check valve 31 will be prevented from flowing backwards, so the impeller 20 and the suction port will be blocked. Only the water does not return to the side of the filter 30 and flows out of the vessel through the filter 32. Dust accumulated inside the filter 32 can be easily removed and cleaned by removing the filter 32 from the pump chamber 27.

In addition, if debris gets wrapped around the blade 20 or transmission shaft 18, or if large debris gets clogged in the pump chamber 27 or suction pipe 29, you can easily remove the screws between the bearing member 28 and the pump chamber 27. Can be cleaned and removed.

Furthermore, since the suction pipe 29 and the pump chamber 27 are connected by fitting the ring-shaped concavo-convex portion, the rotation of the suction pipe 29 relative to the pump chamber 27 is smooth, and there is no leakage of water from this connection portion.

According to the aquarium cleaner shown in the above-mentioned embodiment, the direction of the suction pipe for sucking water and debris can be freely adjusted, so that it is possible to clean any part of the water tank, such as the surface, the water, or the bottom of the water tank. Moreover, since the inflow water and the discharge water are oriented in one direction so that they do not interfere with each other, the flow of water is smooth, the pump efficiency is high, and the efficiency of garbage collection is high.

In this way, according to the present invention, the suction pipe is rotatably mounted in the pump chamber so that the position of the suction port can be adjusted, and further, an adjustment flange is slidably and fixably mounted on the outer periphery of the connecting tube which connects the power supply chamber and the pump chamber.
Furthermore, since the collection filter and drain outlet are located on the opposite side of the pump chamber from where the suction pipe is attached, it is possible to clean debris from the entire area of the tank using a cleaner with a simple configuration.Furthermore, when cleaning such an entire area, the depth of the cleaner in the tank and the position of the suction port can be easily adjusted, resulting in various effects such as high pump efficiency and high debris collection efficiency.
