Utility Model Registration No. 3197467

Therefore, the object of the present invention is to provide an aquarium cleaning tool that improves the efficiency of cleaning the inner wall surface of the aquarium.

The aquarium cleaning tool comprises an operating member arranged on the outer wall surface of the aquarium, and an inner wall cleaning member arranged on the inner wall surface of the aquarium facing the operating member across the wall of the aquarium, the inner wall cleaning member comprising a first inner wall cleaning section and a second inner wall cleaning section capable of magnetically attracting the operating member, the first inner wall cleaning section and the second inner wall cleaning section being arranged opposite each other.

With this configuration, the first inner wall cleaning unit and the second inner wall cleaning unit can each be brought into close contact with the inner wall surface by magnetic attraction with the operating member. This allows the cleaning unit (first inner wall cleaning unit or second inner wall cleaning unit) to be brought into close contact with the inner wall surface of the aquarium to be changed as appropriate, thereby improving the cleaning efficiency of the inner wall surface.

FIG. 1 is a perspective view of an aquarium cleaning tool according to one embodiment. FIG. 2 is a perspective view of the aquarium cleaning tool according to the embodiment. FIG. 3 is a left side view of the aquarium cleaning tool according to the embodiment. FIG. 4 is an enlarged cross-sectional view taken along line IV-IV in FIG. FIG. 5 is an enlarged cross-sectional view taken along line IV-IV in FIG. 3 with the inner wall cleaning member turned upside down. FIG. 6 is a diagram showing an aquarium cleaning tool according to another embodiment.

The aquarium cleaning tool according to this embodiment will be described below with reference to Figures 1 to 5. Note that in each figure (including Figure 6), the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either.

As shown in Figures 1 to 4, the aquarium cleaning tool 1 is provided with an operating member 2 that is disposed on the outer wall surface W1a of the aquarium and is operated by an operator, and an inner wall cleaning member 3 that is disposed on the inner wall surface W1b of the aquarium facing the operating member 2 with the wall W1 of the aquarium between them and cleans the inner wall surface W1b. The aquarium cleaning tool 1 is held to the wall W1 by magnetic attraction between the operating member 2 and the inner wall cleaning member 3.

The operating member 2 includes an operating cover 21 and an outer wall magnet 22 that is magnetically attracted to the inner wall cleaning member 3. The operating member 2 according to this embodiment further includes an outer wall cleaning section 23 that cleans the outer wall surface W1a. With this configuration, by operating the operating member 2, the inner wall cleaning member 3 follows the operating member 2, and the outer wall surface W1a and the inner wall surface W1b can be cleaned simultaneously.

The operation cover 21 according to this embodiment is a thin, approximately rectangular parallelepiped shape. The operation cover 21 according to this embodiment includes a container-shaped first operation cover 211 with an opening at the left end, a substantially rectangular flat second operation cover 212 that closes the opening of the first operation cover 211, and a square thin plate-shaped third operation cover 213 that is disposed between the first operation cover 211 and the outer wall cleaning unit 23 and holds the outer wall side magnet 22 with the first operation cover 211. The operation cover 21 may be, for example, a thin, approximately cylindrical shape.

The first operation cover 211 includes a handle portion 211a that facilitates operation of the operation member 2, a first outer wall side step surface 211b to which the outer wall cleaning portion 23 is attached, a second outer wall side step surface 211c to which the third operation cover 213 is attached, and an outer wall side magnet positioning portion 211d that positions the outer wall side magnet 22.

The handle portion 211a is a flange that protrudes in the up, down, left and right directions from the left end of the first operation cover 211. The first outer wall step surface 211b is a surface that is positioned at a position recessed to the left from the right end surface of the first operation cover 211.

The second outer wall side step surface 211c is a surface that is positioned at a position recessed to the left of the first outer wall side step surface 211b. The outer wall side magnet positioning portion 211d is container-shaped with an opening on the right side, and is positioned facing the left of the second outer wall side step surface 211c. The second outer wall side step surface 211c and the outer wall side magnet positioning portion 211d are positioned in the same number (2 locations) as the outer wall side magnets 22.

The first operation cover 211 is made of a transparent resin (e.g., PS). The second operation cover 212 is made of a white resin (e.g., ABS) and is positioned so that the outer wall magnet 22 is hidden by the second operation cover 212 when viewed from the left side. This configuration makes it difficult to see the outer wall magnet 22 and allows the operation member 2 to blend in with the rest of the interior. This makes it possible to prevent the operation member 2 from spoiling the aesthetic appearance of the area around the aquarium, for example.

The third operation cover 213 is made of, for example, a PET film, and is attached to the second outer wall side step surface 211c so as to cover the outer wall side magnet 22 positioned by the outer wall side magnet positioning portion 211d. When the third operation cover 213 is attached to the second outer wall side step surface 211c, the right surface of the third operation cover 213 is flush with the first outer wall side step surface 211b. This allows the outer wall cleaning portion 23 to be attached to a uniform surface. The third operation cover 213 may be, for example, a nylon or polyester film, or a thin plate coated with acrylic resin, epoxy resin, polyester resin, or the like. The third operation cover 213 may also be configured to be formed by directly coating the right surface of the outer wall side magnet 22 and the second outer wall side step surface 211c with acrylic resin, epoxy resin, polyester resin, or the like.

The outer wall magnets 22 are, for example, neodymium magnets, and an even number of them are arranged. In this embodiment, two outer wall magnets 22 are arranged in a vertical line, and the magnet size is larger than the inner wall magnet 32 described later. With this configuration, the magnetic force of the inner wall magnet 32 can be weakened, so the inner wall magnet 32 can be made smaller. This allows, for example, the inner wall cleaning member 3 to be made thinner, and the risk of the inner wall cleaning member 3 damaging the living organisms in the aquarium can be reduced. In addition, by increasing the size of the outer wall magnet 22, the magnetic attraction force with the inner wall magnet 32 can be strengthened, and the inner wall cleaning member 3 can be prevented from separating from the operating member 2 while cleaning the inner wall surface W1b.

In addition, the outer wall magnet 22 in this embodiment is arranged so that its magnetic poles face the outer wall cleaning unit 23 and the magnetic poles of adjacent magnets are different (for example, the magnetic poles on the right side are the north pole and the south pole from the top).

The exterior wall cleaning part 23 is made of, for example, nylon or polyester fabric, felt, etc., and is attached to the first exterior wall step surface 211b and the third operation cover 213. With this configuration, the exterior wall cleaning part 23 can remove dirt adhering to the exterior wall surface W1a and prevent the exterior wall surface W1a from being damaged. If the operation member 2 does not have the exterior wall cleaning part 23, a cushioning material that prevents the exterior wall surface W1a from being damaged may be used instead of the exterior wall cleaning part 23.

The inner wall cleaning member 3 includes an inner wall cleaning cover 31, an inner wall side magnet 32 that magnetically attracts the outer wall side magnet 22, and a first inner wall cleaning part 33 and a second inner wall cleaning part 34 that clean the inner wall surface W1b. With this configuration, the first inner wall cleaning part 33 and the second inner wall cleaning part 34 can each be brought into close contact with the inner wall surface by magnetic attraction with the operating member 2. This allows the cleaning part (first inner wall cleaning part 33 or second inner wall cleaning part 34) that is brought into close contact with the inner wall surface W1b of the water tank to be changed as appropriate (for example, when the first brush 33a or the second brush 34a described below becomes dirty), thereby improving the cleaning efficiency of the inner wall surface.

The inner wall cleaning cover 31 according to this embodiment is a thin, approximately rectangular parallelepiped shape. The inner wall cleaning cover 31 according to this embodiment includes a first inner wall cleaning cover 311 that is disposed on the left side and has a container-like shape with an opening on the right side, and a second inner wall cleaning cover 312 that is disposed on the right side and has a container-like shape with an opening on the left side. The inner wall cleaning cover 31 may be, for example, a thin, approximately cylindrical shape.

The first inner wall cleaning cover 311 and the second inner wall cleaning cover 312 are formed of black resin (e.g., ABS). This makes dirt on the inner wall cleaning cover 31 less noticeable. The first inner wall cleaning cover 311 and the second inner wall cleaning cover 312 are integrated without any gaps by ultrasonic welding. This prevents the adhesive components from dissolving and contaminating the water in the tank. In addition, air can be trapped inside the inner wall cleaning cover 31, allowing the inner wall cleaning member 3 to float in the water. This makes it easy for an operator to retrieve the inner wall cleaning member 3, for example, by floating the inner wall cleaning member 3 on the water surface when the inner wall cleaning member 3 separates from the operating member 2.

The first inner wall cleaning cover 311 has a first inner wall side step surface 311a to which the first inner wall cleaning part 33 is attached, and an inner wall side magnet positioning part 311b that positions the inner wall side magnet 32.

The first inner wall side step surface 311a is a surface that is positioned at a position recessed to the right from the left end surface of the first inner wall cleaning cover 311. The inner wall side magnet positioning parts 311b are container-shaped with an opening on the right side, and are arranged on the right side of the first inner wall cleaning cover 311 in the same number as the inner wall side magnets 32 (two locations).

The second inner wall cleaning cover 312 has a second inner wall side step surface 312a to which the second inner wall cleaning part 34 is attached, and a protrusion part 312b that holds the inner wall side magnet 32 by the inner wall side magnet positioning part 311b.

The second inner wall side step surface 312a is a surface that is positioned at a position recessed to the left from the right end surface of the second inner wall cleaning cover 312, and is positioned opposite the first inner wall side step surface 311a. The protrusion portion 312b is an annular protrusion that protrudes leftward from the left side of the second inner wall cleaning cover 312, and is positioned opposite the inner wall side magnet positioning portion 311b. The protrusion portions 312b are positioned in the same number (two locations) as the inner wall side magnets 32.

The inner wall side magnets 32 are, for example, neodymium magnets, and an even number of them are arranged between the first inner wall cleaning part 33 and the second inner wall cleaning part 34. In this embodiment, two inner wall side magnets 32 are arranged in a vertical line, with the magnetic poles facing the first inner wall cleaning part 33 and the second inner wall cleaning part 34, and the magnetic poles of adjacent magnets are different (for example, the magnetic poles on the left side are the S pole and the N pole from the top). Note that while FIG. 4 shows a state in which the operating member 2 and the first inner wall cleaning part 33 are magnetically attracted to each other, the operating member 2 and the second inner wall cleaning part 34 can be magnetically attracted to each other by rotating the inner wall cleaning member 3 clockwise or counterclockwise (see FIG. 5).

With this configuration, the operating member 2 and the first inner wall cleaning part 33 or the second inner wall cleaning part 34 can be magnetically attracted to each other by the outer wall side magnet 22 and the inner wall side magnet 32. This makes it possible to strengthen the magnetic attraction force between the operating member 2 and the inner wall cleaning member 3, and to increase the cleaning power of the outer wall surface W1a and the inner wall surface W1b, for example.

In addition, the inner wall side magnet 32 according to this embodiment is positioned closer to the first inner wall cleaning unit 33 than the second inner wall cleaning unit 34. That is, the first distance L1 from the inner wall side magnet 32 to the first inner wall side step surface 311a is shorter than the second distance L2 from the inner wall side magnet 32 to the second inner wall side step surface 312a. With this configuration, the magnetic attraction force between the operating member 2 and the first inner wall cleaning unit 33 can be made stronger than the magnetic attraction force between the operating member 2 and the second inner wall cleaning unit 34. This allows the first inner wall cleaning unit 33 and the second inner wall cleaning unit 34 to be used differently depending on the dirt on the inner wall surface W1b, and for example, the cleaning efficiency of the inner wall surface W1b can be improved.

The first inner wall cleaning part 33 according to this embodiment includes a first brush 33a with short bristles made of resin (e.g., nylon, polyester) and is attached to the first inner wall side step surface 311a. The second inner wall cleaning part 34 according to this embodiment includes a second brush 34a with longer bristles than the first brush 33a and is attached to the second inner wall side step surface 312a.

With this configuration, the first inner wall cleaning unit 33 and the second inner wall cleaning unit 34 can use different types of brushes. This allows, for example, the efficiency of cleaning the inner wall surface W1b to be improved by removing dirt from the inner wall surface W1b with the first brush 33a and then polishing it with the second brush 34a as a finishing touch. Note that the first brush 33a and the second brush 34a may be, for example, the same brush or may be an ultra-hard brush. The first inner wall cleaning unit 33 and the second inner wall cleaning unit 34 may be, for example, a cloth or a sponge.

As described above, the aquarium cleaning tool 1 according to this embodiment comprises an operating member 2 arranged on the outer wall surface W1a of the aquarium, and an inner wall cleaning member 3 arranged on the inner wall surface W1b of the aquarium facing the operating member 2 across the wall W1 of the aquarium, and the inner wall cleaning member 3 comprises a first inner wall cleaning part 33 and a second inner wall cleaning part 34 that can be magnetically attracted to the operating member 2, and the first inner wall cleaning part 33 and the second inner wall cleaning part 34 are arranged facing each other.

With this configuration, the first inner wall cleaning part 33 and the second inner wall cleaning part 34 can each be brought into close contact with the inner wall surface by magnetic attraction with the operating member 2. This allows the cleaning part (first inner wall cleaning part 33 or second inner wall cleaning part 34) to be brought into close contact with the inner wall surface W1b of the water tank to be changed as appropriate (for example, when the first brush 33a or the second brush 34a described below becomes dirty), thereby improving the cleaning efficiency of the inner wall surface.

In addition, in the aquarium cleaning tool 1 according to this embodiment, the operating member 2 has an even number of outer wall magnets 22, the inner wall cleaning member 3 has the same number of inner wall magnets 32 as the outer wall magnets 22, the outer wall magnets 22 are arranged in an aligned manner so that their magnetic poles face the outer wall surface contact portion (outer wall cleaning portion 23) of the operating member 2 and adjacent magnets have different magnetic poles, and the inner wall magnets 32 are arranged between the first inner wall cleaning portion 33 and the second inner wall cleaning portion 34, and are arranged in an aligned manner so that their magnetic poles face the first inner wall cleaning portion 33 and the second inner wall cleaning portion 34 and adjacent magnets have different magnetic poles.

With this configuration, the operating member 2 and the first inner wall cleaning part 33 or the second inner wall cleaning part 34 can be magnetically attracted to each other by the outer wall side magnet 22 and the inner wall side magnet 32. This makes it possible to strengthen the magnetic attraction force between the operating member 2 and the inner wall cleaning member 3, and to increase the cleaning power of the outer wall surface W1a and the inner wall surface W1b, for example.

In addition, in the aquarium cleaning tool 1 according to this embodiment, the inner wall side magnet 32 is positioned closer to the first inner wall cleaning part 33 than to the second inner wall cleaning part 34.

With this configuration, the magnetic attraction force between the operating member 2 and the first inner wall cleaning unit 33 can be made stronger than the magnetic attraction force between the operating member 2 and the second inner wall cleaning unit 34. This makes it possible to selectively use the first inner wall cleaning unit 33 and the second inner wall cleaning unit 34 depending on the degree of dirt on the inner wall surface W1b, thereby improving the cleaning efficiency of the inner wall surface W1b, for example.

In addition, in the aquarium cleaning tool 1 according to this embodiment, the inner wall cleaning member 3 is configured to be able to float in water when separated from the operating member 2.

With this configuration, when the inner wall cleaning member 3 separates from the operating member 2, the inner wall cleaning member 3 floats to the water surface. This makes it easier for an operator to retrieve the inner wall cleaning member 3, for example.

In addition, in the aquarium cleaning tool 1 according to this embodiment, the first inner wall cleaning part 33 is equipped with a first brush 33a, and the second inner wall cleaning part 34 is equipped with a second brush 34a whose bristles are longer than those of the first brush 33a.

With this configuration, the type of brush can be changed between the first inner wall cleaning unit 33 and the second inner wall cleaning unit 34. This allows, for example, the efficiency of cleaning the inner wall surface W1b to be improved by removing dirt from the inner wall surface W1b with the first brush 33a and then polishing it with the second brush 34a as a finishing touch.

The aquarium cleaning tool 1 is not limited to the configuration of the embodiment described above, nor is it limited to the effects described above. Furthermore, the aquarium cleaning tool 1 can of course be modified in various ways without departing from the spirit of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. related to the various modified examples described below and adopt them in the configurations, methods, etc. related to the embodiment described above.

(1) In this embodiment, the outer wall side magnets 22 and the inner wall side magnets 32 are arranged in pairs, one above the other. However, the outer wall side magnets 22 and the inner wall side magnets 32 are not limited to this configuration.

For example, as shown in FIG. 6, six outer wall magnets 22 and six inner wall magnets 32 may be arranged in two rows. With this configuration, the surface area of the outer wall cleaning section 23, the first inner wall cleaning section 33, and the second inner wall cleaning section 34 (see FIG. 4) can be increased, and the cleaning efficiency of the outer wall surface W1a (see FIG. 4) and the inner wall surface W1b (see FIG. 4) can be improved.

(2) In addition, the inner wall cleaning member 3 according to this embodiment is configured to include an inner wall side magnet 32 and two outer wall side magnets 22. However, this is not limited to the above configuration, and the inner wall cleaning member 3 may be configured to include a ferromagnetic material such as iron and an odd number of outer wall side magnets 22 may be arranged.
