Description

Technical Field

[0001] This invention relates to the field of aquarium cleaning technology, specifically to a magnetic aquarium brush and its cleaning method. Background Technology

[0002] Aquarium cleaning is crucial for maintaining water quality and promoting fish health. During daily use, fish waste and food accumulate in the tank, decaying and forming algae that adheres to the tank walls, making it difficult to keep the water clean. To maintain cleanliness, users use filtration systems, but the water quality can still deteriorate due to the contamination of waste and food, forming toxic nitrites that harm the fish. Therefore, regular water changes are essential to prevent fish deaths.

[0003] Besides changing the aquarium water, the main problem is that if the algae adhering to the aquarium isn't removed promptly during water changes, the newly added water will quickly become contaminated. Normally, after draining the water, the aquarium walls are wiped clean with a cloth. However, for larger, deeper aquariums, an adult's arm is too long to reach the bottom and sides to clean them. Over time, a large amount of algae accumulates on the sides and bottom of the aquarium, severely affecting water quality. Summary of the Invention

[0016] One end of the blade holder is an insertion end, and the other end is an external end. The side wall of the external end extends with a limiting piece 2. The side wall of the blade holder is provided with a matching block. The side wall of the blade 2 is provided with an insertion hole for insertion with the matching block. The insertion end is inserted into the blade groove along the transverse insertion port and fits against the blocking part. The limiting piece 2 abuts against the insertion port. The blade 2 is located in the guide groove and the cutting edge of the blade 2 extends out of the blade groove opening.

[0017] In a further embodiment, a positioning hole 1 is provided on the outer wall of the end of the blade groove near the insertion port, and a protrusion 3 matching the positioning hole 1 is provided on the side wall of the end of the blade holder near the limiting piece 2.

[0018] The blocking part is provided with a positioning hole two, and the side wall of the knife holder facing the blocking part is provided with a protrusion four that is inserted into the positioning hole two.

[0019] In a further embodiment, a material leakage notch is provided on the clean sidewall of the outer casing one, near the knife groove.

[0020] In a further embodiment, a T-shaped snap-fit ​​notch is provided on one of the short side walls of the outer casing 2, and a T-shaped holding rod is snapped into the T-shaped snap-fit ​​notch;

[0021] The second outer shell has an adhesive layer on its bonding sidewall.

[0022] In a further embodiment, there are two built-in magnet blocks, namely magnet block one and magnet block two, and two external magnet blocks, namely magnet block three and magnet block four. The magnetic poles of magnet block one and magnet block three are arranged oppositely on their opposite side walls, and the magnetic poles of magnet block two and magnet block four are arranged oppositely on their opposite side walls.

[0023] The magnetic poles of magnet block one and magnet block two are arranged oppositely on the side wall facing the outer shell one;

[0024] The magnetic poles of the second magnet block and the four magnet blocks facing the outer shell second are set to be opposite.

[0025] A method for cleaning a fish tank with a magnetic brush includes the following steps:

[0026] A1. To perform cleaning, place the S pole of magnet one and the N pole of magnet three facing each other, and the N pole of magnet two and the S pole of magnet four facing each other. According to the principle that opposite poles of magnets attract each other, magnet one and magnet three can be attracted to each other, and magnet two and magnet four can be attracted to each other. The user stands outside the fish tank, holds the outer shell two against the outer wall of the fish tank, and faces the outer shell one. This allows the entire cleaning component to be set up in the air through the side wall of the fish tank. The user moves the outer shell two horizontally, and under the action of magnetic force, the blade moves along the inner wall of the fish tank to scrape.

[0027] A2. When using the cleaning cloth for cleaning, simply flip the outer casing one over so that the cleaning cloth faces directly onto the inner wall of the aquarium. At the same time, invert the outer casing two in a vertical plane, with magnet three at the lower position and magnet four at the higher position. The N pole of magnet one and the S pole of magnet four are directly opposite each other, and the S pole of magnet two and the N pole of magnet three are directly opposite each other. In this state, according to the principle of attraction between opposite poles of magnets, magnet one and magnet four can be attracted to each other, and magnet two and magnet three can be attracted to each other. The user stands outside the aquarium, holds the outer casing two against the outer wall of the aquarium, and faces the outer casing one. This allows the entire cleaning component to be suspended in the air through the side wall of the aquarium. The user holds the outer casing two and moves it horizontally. Under the action of magnetic force, the cleaning cloth moves along the inner wall of the aquarium to wipe.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention integrates a cleaning component inside the aquarium and attaches it to the circumferential side wall of the aquarium. Simultaneously, a handheld component is attached to the outer side wall of the aquarium. The built-in and external magnets attract each other, allowing the cleaning component to move synchronously and in the same direction across the aquarium side wall simply by moving the handheld component. Depending on the cleaning needs, a cleaning cloth or a knife can be positioned directly opposite the aquarium wall. During the movement of the cleaning component, the inner wall of the aquarium is wiped clean with the cleaning cloth or scraped clean with the knife. This invention is suitable for large and deep aquariums, eliminating the need for handheld cleaning tools to enter the aquarium for cleaning, thus improving aquarium cleaning efficiency.

[0030] 2. The blades in this invention come in two styles: one is a plastic blade that is directly installed in the blade groove, and the other is a metal blade equipped with a blade holder installed in the blade groove. Both types of blades can be used to scrape the inner wall of the aquarium. The plastic blade is used to clean various algae and scale that adhere to the inner wall of the aquarium in a short period of time, while the metal blade is suitable for cleaning various harder algae and scale that adhere to the inner wall of the aquarium for a long time. Users can choose according to their needs.

[0031] 3. Based on cleaning needs, when cleaning the inner wall of the aquarium on the side facing the wall, it is inconvenient for the user to hold the handheld part and move it on the outer wall of the aquarium on the side facing the wall. Therefore, a T-shaped handle is used to remotely operate the handheld part to move on the outer wall of the aquarium on the side facing the wall, so as to meet the operation needs of moving the cleaning part synchronously on the inner wall of the aquarium.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This embodiment provides a magnetic brush for aquariums, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a cleaning component and a handheld component. The cleaning component includes a housing 2 and a cover 22 detachably connected to the housing 2. The cover 22 and the housing 2 are assembled together by snap-fit ​​and slot-fitting or by tight insertion, so that the interior of the housing 2 is relatively sealed. The side wall of the housing 2 facing away from the cover 22 is the cleaning side wall. A blade groove 27 is provided on the cleaning side wall, and a blade is detachably installed in the blade groove 27. When the cleaning side wall is facing the inner wall of the aquarium, the blade is suitable for scraping various algae and scale residues on the inner wall of the aquarium.

[0047] Meanwhile, the handheld component includes a second outer shell 12 and a second outer cover 1 detachably connected to the second outer shell 12. The second outer cover 1 and the second outer shell 12 are assembled together by means of snap-fit ​​and slot-fitting or by tight insertion. The side wall of the second outer shell 12 facing away from the second outer cover 1 is a fitting side wall. A fitting layer 15 is provided on the fitting side wall of the second outer shell 12. The fitting layer 15 can be made of felt fabric, which is used to fit against the outer wall of the aquarium and is not easy to scratch the outer wall of the aquarium.

[0048] Furthermore, a support base 23 is provided inside the outer shell 12. A placement groove 1 is formed on the side wall of the support base 23 facing the cleaning side wall, and a built-in magnet is placed in placement groove 1. A placement groove 2 is provided inside the outer shell 22, and an external magnet is placed in placement groove 2. A baffle 11 is placed over the opening of placement groove 2. The purpose of adding baffle 11 is to weaken the magnetic force of the external magnet on the side near the outer shell 22. The magnetic poles of the external and internal magnets are opposite on opposite sides, generating a mutual attraction force. This allows the outer shell 22 to be held outside the aquarium while the outer shell 12 is placed inside the aquarium, directly opposite the outer shell 12 across the aquarium side wall. The mutually attracting external and internal magnets allow the outer shell 12 to be suspended and attached to the inner wall of the aquarium. Whenever the outer shell 22 moves, the outer shell 12 moves synchronously.

[0049] Meanwhile, a cleaning cloth 21 is provided on the side wall of the cover 22 facing away from the outer shell 2. By flipping the outer shell 2 over, the outer wall of the cleaning cloth 21 is brought into contact with the inner wall of the aquarium for wiping and cleaning. The cleaning cloth 21 is made of microfiber, which has the characteristics of strong water absorption, thorough cleaning, and no damage to the surface. It can also be reused and is not easily deformed or damaged, making it suitable for wiping and cleaning the inner wall of the aquarium.

[0050] Specifically, such as Figure 10 As shown, there are two built-in magnets, namely magnet block 1 (25) and magnet block 2 (26), and two external magnets, namely magnet block 3 (13) and magnet block 4 (14). It should be noted that, as... Figure 11 As shown, the magnetic poles of magnet block 1 25 and magnet block 3 13 on opposite side walls are arranged with opposite magnetic poles, and the magnetic poles of magnet block 2 26 and magnet block 4 14 on opposite side walls are arranged with opposite magnetic poles; the magnetic poles of magnet block 1 25 and magnet block 2 26 on the side walls facing outer shell 1 2 are arranged with opposite magnetic poles, and magnet block 1 25 and magnet block 2 26 attract each other when facing each other; the magnetic poles of magnet block 2 26 and magnet block 4 14 on the side walls facing outer shell 2 12 are arranged with opposite magnetic poles, and magnet block 2 26 and magnet block 4 14 attract each other when facing each other.

[0051] For example, when using a knife for cleaning, refer to... Figure 11As shown, the S pole of magnet 1 25 and the N pole of magnet 3 13 are directly opposite each other, and the N pole of magnet 2 26 and the S pole of magnet 4 14 are directly opposite each other. In this state, according to the principle of attraction between opposite poles of magnets, magnet 1 25 and magnet 3 13 can be attracted to each other, and magnet 2 26 and magnet 4 14 can be attracted to each other. The cleaning parts are suspended in the air through the aquarium glass to achieve the purpose of moving the scraper along the inner wall of the aquarium for cleaning.

[0052] For another example, cleaning the fish tank can be completed simply by wiping with cleaning cloth 21, without the need for knives or scrapers. Therefore, it is only necessary to flip the outer casing 2, place the cleaning cloth 21 face-up against the inner wall of the fish tank, and simultaneously invert the outer casing 12 in a vertical plane. Figure 12 As shown, magnet block 3 (13) is at a lower position, and magnet block 4 (14) is at a higher position. Therefore, referring to... Figure 13 As shown, the N pole of magnet 1 25 and the S pole of magnet 4 14 are directly opposite each other, and the S pole of magnet 2 26 and the N pole of magnet 3 13 are directly opposite each other. In this state, according to the principle of attraction between opposite poles of magnets, magnet 1 25 and magnet 4 14 can be attracted to each other, and magnet 2 26 and magnet 3 13 can be attracted to each other. The cleaning parts are suspended in the air through the aquarium glass so as to move and wipe along the inner wall of the aquarium.

[0053] Furthermore, the first design structure of the cutting tool, such as Figure 3 and Figure 4 As shown, the knife includes a blade 4. One side of the groove 27 extends to the side wall of the outer shell 2, serving as the insertion port for the blade 4. The other side wall of the groove 27 is provided with a blocking part 272. One end of the blade 4 is the insertion end, and the other end is the external end. A limiting piece 43 extends from the side wall of the external end. The insertion end of the blade 4 is inserted laterally into the groove 27 along the transverse insertion port and fits against the blocking part 272. The limiting piece 43 abuts against the insertion port, so that the blade 4 is stably installed in the groove 27. At the same time, the blade of the blade 4 extends out of the groove 27. The blade 4 moves along the inner wall of the aquarium with the outer shell 2. During the movement, the blade of the blade 4 scrapes various algae and scale on the inner wall of the aquarium.

[0054] To increase the stability of the blade 4 when inserted into the slot 27, a positioning hole 28 is provided on the outer wall of the slot 27 near the insertion port. The side wall of the blade 4 near the limiting piece 43 has a protrusion 41 that matches the positioning hole 28. At the same time, a second positioning hole 271 is provided on the blocking part 272. The side wall of the blade 4 facing the blocking part 272 has a protrusion 42 that engages with the second positioning hole 271. When the blade 4 is inserted laterally into the slot 27, the protrusion 41 can be engaged in the positioning hole 28, and the protrusion 42 can be engaged in the positioning hole 271. By limiting the blade 4 at two points, the installation stability of the blade 4 is enhanced, and the blade 4 is prevented from jumping off the inner wall of the aquarium during the scraping process. This would prevent the blade from being unable to scrape the inner wall of the aquarium during the movement of the aquarium, requiring multiple scrapings and resulting in low cleaning efficiency.

[0055] The aforementioned blade 4 is made of plastic (PVC plastic is sufficient) and is used to scrape off various algae and scale that remain in the fish tank for a short period of time.

[0056] In addition to the first structure mentioned above, the second design structure of the cutting tool is as follows: (See...) Figure 5 , Figure 6 and Figure 7 As shown, the tool includes a second blade 52 and a blade holder 5. One side of the blade groove 27 extends to the side wall of the outer casing 2, serving as the insertion port for the blade holder 5 and the second blade 52. The other side wall of the blade groove 27 has a blocking part 272. One end of the blade holder 5 is the insertion end, and the other end is the external end. A limiting piece 55 extends from the side wall of the external end. A matching block 54 is provided on the side wall of the blade holder 5. An insertion hole 53 is provided on the side wall of the second blade 52 to engage with the matching block 54. The insertion end is inserted laterally into the blade groove 27 along the transverse insertion port and fits against the blocking part 272. The limiting piece 55 abuts against the insertion port, ensuring that the second blade 52 is stably installed in the blade groove 27. At the same time, the second blade 52 is located in the guide groove, and the cutting edge of the second blade 52 extends out of the groove opening of the blade groove 27. The second blade 52 moves along the inner wall of the aquarium with the outer casing 2. During the movement, the cutting edge of the second blade 52 scrapes away various algae and scale on the inner wall of the aquarium.

[0057] A positioning hole 28 is provided on the outer wall of the blade groove 27 near the insertion port. A protrusion 51 matching the positioning hole 28 is provided on the side wall of the blade holder 5 near the limiting piece 55. At the same time, a positioning hole 271 is provided on the blocking part 272, and a protrusion 56 that engages with the positioning hole 271 is provided on the side wall of the blade holder 5 facing the blocking part 272. When the blade 2 52 and the blade holder 5 are inserted laterally into the blade groove 27, the protrusion 3 51 can be engaged in the positioning hole 28, and the protrusion 4 56 can be inserted into the positioning hole 271. Through the two-point limiting method, the installation stability of the blade 2 52 is enhanced, and the blade 2 52 is prevented from jumping off the inner wall of the aquarium during the scraping process. This would prevent the blade from being unable to scrape the inner wall of the aquarium during the movement of the aquarium, requiring multiple scrapings and resulting in low cleaning efficiency.

[0058] The aforementioned blade 2, 52, is a metal blade (such as a thin stainless steel blade; a 1mm thick blade is sufficient). It is used for scraping away hardened algae and scale that have accumulated in the aquarium over a long period. Users can choose either blade 1, 4, or blade 2, 52 as their scraping tool according to their needs.

[0059] In addition, whether it is a plastic blade or a metal blade, there are two blades. One blade is located at the front of the direction of travel, and the other blade is located at the rear of the direction of travel, which is equivalent to the belly (middle position) of the outer shell 2. This ensures that the blade can be evenly stressed in all four directions and fit perfectly against the inner wall of the aquarium to achieve the best scraping effect.

[0060] The specific cleaning process is as follows: When using a blade as the cleaning tool, place the cleaning sidewall facing the inner wall of the aquarium. The mutually attracted external and internal magnets will lift the outer shell 12 and attach it to the inner wall of the aquarium. By moving the outer shell 12 from the outside of the aquarium, the blade will move synchronously through the sidewall, thus scraping away algae and scale residue. When using a cleaning cloth 21 as the cleaning tool, flip the outer shell 12 over and place its outer wall against the inner wall of the aquarium. The mutually attracted external and internal magnets will lift the outer shell 12 and attach it to the inner wall of the aquarium. By moving the outer shell 22 from the outside of the aquarium, the cloth will move synchronously through the sidewall, thus wiping and cleaning the inner wall of the aquarium.

[0061] In summary, simply moving the handheld component allows the cleaning component to move synchronously and in the same direction across the side wall of the aquarium. Depending on the cleaning needs, the cleaning cloth 21 or the blade can be positioned directly opposite the inner wall of the aquarium. During the movement of the cleaning component, the inner wall of the aquarium can be wiped clean with the cleaning cloth 21 or scraped clean with the blade. This method is suitable for large and deep aquariums, eliminating the need to manually enter the aquarium to perform cleaning operations, thus improving the efficiency of aquarium cleaning.

[0062] To improve the sealing performance inside the outer casing 2, a sealing element such as... can be added between the cover 22 and the outer casing 2. Figure 2 The rubber gasket 24 shown is to prevent water from entering the outer casing 2 when it is placed inside the fish tank. Water inside the outer casing 2 would increase its weight and affect the resistance to its movement against the inner wall of the fish tank. Simultaneously, to prevent water from entering the outer casing 2 and causing the internal magnet to rust and demagnetize, and to ensure that the inner casing 2 is relatively sealed and buoyant, the outer casing 2 can float to the surface for easy retrieval after being separated from the outer casing 12.

[0063] In this embodiment, furthermore, a material leakage notch 210 is provided on the clean sidewall of the outer casing 2, near the knife groove 27, such as... Figure 9 As shown, regardless of the type of blade used, during the scraping process, various algae and scale will move synchronously with the blade as it moves. By adding a material leakage notch 210, various algae and scale can be pushed into the material leakage notch 210 and then discharged from the openings on both sides of the material leakage notch 210, thus avoiding the accumulation of a large amount of dirt at the blade edge and affecting the cleaning efficiency of the blade.

[0064] A ball bearing 29 is embedded in the upper corner of the cleaning sidewall, and the outer wall of the ball bearing 29 protrudes from the cleaning sidewall, such as... Figure 2 As shown, there are four ball bearings 29, distributed at the four corners of the cleaning sidewall. The ball bearings 29 protrude from the outer wall of the cleaning sidewall and are in the same plane as the blade 4 or the blade 52 extending from the groove 27. In this way, during the cleaning process, the ball bearings 29 roll and fit against the inner wall of the aquarium, reducing the resistance of the outer shell 2 moving along the inner wall of the aquarium while ensuring that the blade can make seamless contact with the inner wall of the aquarium, thus achieving the purpose of scraping and cleaning the inner wall of the aquarium.

[0065] Furthermore, another advantage of adding the ball bearings 29 is that it creates a gap between the cleaning sidewall and the inner wall of the aquarium. This prevents the dirt scraped off by the blade from accumulating on the cleaning sidewall, thus avoiding a large accumulation of dirt between the cleaning sidewall and the inner wall of the aquarium, which would affect the cleaning efficiency of the blade. At the same time, the four ball bearings 29 create a gap between the outer casing 2 and the aquarium glass, preventing fine sand and hard limescale from getting stuck between the outer casing 2 and the glass and causing scratches on the glass.

[0066] like Figure 8 As shown, a T-shaped snap-fit ​​notch 16 is provided on one of the short side walls of the outer casing 2 12. A T-shaped handle 3 is snapped into the T-shaped snap-fit ​​notch 16. Based on cleaning needs, when cleaning the inner wall of the aquarium against the wall, it is inconvenient for the user to hold the handheld component and move it along the outer wall of the aquarium against the wall. Therefore, the T-shaped handle 3 allows for remote operation of the handheld component to move along the outer wall of the aquarium facing the wall, thus meeting the operational requirement of synchronously moving the cleaning component along the inner wall of the aquarium. In summary, without compromising the overall shape of the product, hidden T-shaped snap-fit ​​notches 16 are designed on both short side walls of the outer casing 2 12 for splicing with the T-shaped handle 3. This facilitates control of the outer casing 2 12 via the T-shaped handle 3, making it convenient to clean the inner wall of the aquarium against the wall.

[0067] This embodiment also discloses a method for cleaning a fish tank magnetic brush, including the following steps:

[0068] A1. To perform cleaning using a blade, position the S pole of magnet 1 (25) opposite the N pole of magnet 3 (13), and the N pole of magnet 2 (26) opposite the S pole of magnet 4 (14). Based on the principle that opposite poles attract, magnet 1 (25) and magnet 3 (13) will attract each other, as will magnet 2 (26) and magnet 4 (14). The user stands outside the fish tank, holding the outer casing 2 (12) against the outer wall of the fish tank, directly opposite outer casing 1 (2). This allows the entire cleaning component to be suspended in mid-air over the side wall of the fish tank. The user then moves the outer casing 2 (12) horizontally, and under the influence of the magnetic force, the blade moves along the inner wall of the fish tank to scrape.

[0069] A2. When using the cleaning cloth 21 for cleaning, simply flip the outer casing 1 2 and place the cleaning cloth 21 facing the inner wall of the fish tank. At the same time, invert the outer casing 2 12 in a vertical plane, with the magnet 3 13 at the lower position and the magnet 4 14 at the higher position. The N pole of the magnet 1 25 and the S pole of the magnet 4 14 are directly opposite each other, and the S pole of the magnet 2 26 and the N pole of the magnet 3 13 are directly opposite each other. In this state, according to the principle of attraction between opposite poles of magnets, the magnet 1 25 and the magnet 4 14 can be attracted to each other, and the magnet 2 26 and the magnet 3 13 can be attracted to each other. The user stands outside the fish tank, holds the outer casing 2 12 against the outer wall of the fish tank, and faces the outer casing 1 2.
