Description

Technical Field

[0001] The utility model relates to the technical field of fish tank cleaning, in particular to a magnetic fish tank brush. Background Art

[0002] Fish tank cleaning is an important link to maintain water quality and promote the health of fish. During daily use, fish excrement and fish food will accumulate in the fish tank. When they decay, moss will be generated and adhere to the inner wall of the fish tank, making it difficult to maintain clean water quality in the fish tank. In order to keep the fish tank clean, users will use filtration equipment to filter the water quality. However, the water quality will also deteriorate due to the mixing and soaking of excrement and fish food, forming toxic nitrous acid, which endangers the health of fish. Therefore, the fish tank water needs to be changed regularly to prevent the death of fish.

[0003] In addition to changing the fish tank water, the most important thing is that when changing the water, the moss adhering to the inner wall of the fish tank is not cleaned in time, and the newly changed water will quickly deteriorate due to the presence of moss.

[0041] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] Embodiment. This embodiment provides a fish tank magnetic brush, as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a cleaning component and a handheld component. The cleaning component includes a first housing 2 and a first cover 22 detachably connected to the first housing 2. The first cover 22 and the first housing 2 are assembled together by means of snap - fit with a snap - groove or a tight plug - in method, so that the inside of the first housing 2 is in a relatively enclosed state. One side wall of the first housing 2 facing away from the first cover 22 is a cleaning side wall. A knife groove 27 is formed on the cleaning side wall, and a tool is detachably arranged in the knife groove 27. When the cleaning side wall is facing the inner wall of the fish tank, the tool is suitable for scraping various algae and scale residues on the inner wall of the fish tank.

[0043] At the same time, the handheld component includes a second housing 12 and a second cover 1 detachably connected to the second housing 12. The second cover 1 and the second housing 12 are assembled together by means of snap - fit with a snap - groove or a tight plug - in method. One side wall of the second housing 12 facing away from the second cover 1 is a fitting side wall. A fitting layer 15 is provided on the fitting side wall of the second housing 12. The fitting layer 15 can be made of felt fabric and is used to fit with the outer wall of the fish tank, and it is not easy to scratch the outer wall of the fish tank.

[0044] There is also a support seat 23 arranged inside the first housing 2. A first placement groove is formed on one side wall of the support seat 23 facing the cleaning side wall. An internal magnet block is arranged in the first placement groove. A second placement groove is arranged inside the second housing 12, and an external magnet block is arranged in the second placement groove. And a baffle 11 covers the opening of the second placement groove. The purpose of adding the baffle 11 is to weaken the magnetic force of the external magnet block on the side close to the second cover 1. The opposite side walls of the external magnet block and the internal magnet block are set with different magnetic poles, generating an attractive force that attracts each other. The purpose is that when holding the second housing 12 outside the fish tank and placing the first housing 2 inside the fish tank, with the first housing 2 and the second housing 12 facing each other across the side wall of the fish tank, the external magnet block and the internal magnet block that attract each other can attach the first housing 2 to the inner wall of the fish tank in the air. As long as the second housing 12 moves, the first housing 2 can move synchronously.

[0045] At the same time, a cleaning cloth 21 is provided on one side wall of the first cover 22 facing away from the first housing 2. By flipping the first housing 2, the outer wall of the cleaning cloth 21 is attached to the inner wall of the fish tank to perform a wiping and cleaning operation on the inner wall of the fish tank. Here, the material of the cleaning cloth 21 is made of ultra - fine fiber, which has the characteristics of strong water absorption, thorough cleaning, and no damage to the surface. Moreover, it can be used repeatedly, is not easy to deform or break, and is suitable for wiping and cleaning the inner wall of the fish tank.

[0046] Specifically, as Figure 10 shown, there are two internal magnet blocks, namely magnet block one 25 and magnet block two 26, and two external magnet blocks, namely magnet block three 13 and magnet block four 14. It should be particularly noted that as Figure 11As shown, the magnetic poles of the side walls of magnet block one 25 and magnet block three 13 are arranged differently, and the magnetic poles of the side walls of magnet block two 26 and magnet block four 14 are arranged differently; the magnetic poles of the side walls of magnet block one 25 and magnet block two 26 facing the outer shell one 2 are arranged differently, and magnet block one 25 and magnet block two 26 attract each other when facing each other; magnet block two 26 and magnet block four 14 have different magnetic poles on the side walls facing the outer shell two 12, and magnet block two 26 and magnet block four 14 attract each other when facing each other.

[0047] For example, when using a knife for cleaning operations, refer to Figure 11 As shown, the S pole of magnet block one 25 is directly opposite to the N pole of magnet block three 13, and the N pole of magnet block two 26 is directly opposite to the S pole of magnet block four 14. In this state, according to the principle of opposite magnets attract each other, magnet block one 25 and magnet block three 13 can be adsorbed to each other, and magnet block two 26 and magnet block four 14 can be adsorbed to each other, and the cleaning component can be set in the air through the fish tank glass to achieve the purpose of moving the scraper along the inner wall of the fish tank for cleaning.

[0048] For another example, when the cleaning operation of the fish tank can be completed by wiping with the cleaning cloth 21, there is no need to use a knife or a scraper. Therefore, it is only necessary to flip the housing 1 2, put the cleaning cloth 21 against the inner wall of the fish tank, and at the same time invert the housing 2 12 in the vertical plane, such as Figure 12 As shown, the magnet block 3 13 is at a low position, and the magnet block 4 14 is at a high position. Figure 13 As shown, the N pole of magnet block one 25 is directly opposite to the S pole of magnet block four 14, and the S pole of magnet block two 26 is directly opposite to the N pole of magnet block three 13. In this state, according to the principle of opposite magnets attract each other, magnet block one 25 and magnet block four 14 can be adsorbed to each other, and magnet block two 26 and magnet block three 13 can be adsorbed to each other, and the cleaning component can be set in the air through the glass of the fish tank to achieve the purpose of moving and wiping along the fish tank for cleaning.

[0049] Furthermore, the first design structure of the tool, such as Figure 3 and Figure 4 As shown, the tool includes a blade 4, one side of the knife groove 27 extends to the side wall of the shell 2, which is the insertion port of the blade 4, and the other side wall of the knife groove 27 is provided with a blocking portion 272; one end of the blade 4 is an insertion end, and the other end is an external end, and a limiting piece 43 is extended from the side wall of the external end, and the insertion end of the blade 4 is horizontally inserted into the knife groove 27 along the horizontal insertion port and fits with the blocking portion 272, and the limiting piece 43 is against the insertion port position, so that the blade 4 is stably installed in the knife groove 27, and at the same time, the blade of the blade 4 extends out of the notch of the knife groove 27, and the blade 4 moves along the inner wall of the fish tank with the shell 2, and the blade of the blade 4 scrapes various algae and scale on the inner wall of the fish tank during the movement.

[0050] To increase the stability of the first blade 4 inserted into the knife groove 27, a first positioning hole 28 is provided on the outer wall of one end of the knife groove 27 near the insertion opening. A first bump 41 matching the first positioning hole 28 is provided on the side wall of one end of the first blade 4 close to the first limiting piece 43. At the same time, a second positioning hole 271 is provided on the blocking portion 272. A second bump 42 inserted into the second positioning hole 271 is provided on the side wall of one end of the first blade 4 facing the blocking portion 272. When the first blade 4 is horizontally inserted into the knife groove 27, the first bump 41 can be stuck into the first positioning hole 28, and the second bump 42 is inserted into the second positioning hole 271. By means of two-point position limiting, the installation stability of the first blade 4 is enhanced, avoiding the phenomenon of the first blade 4 jumping during the scraping process against the inner wall of the fish tank, resulting in the situation that the inner wall of the fish tank cannot be scraped during the movement and needs to be scraped multiple times, causing low cleaning efficiency.

[0051] The above-mentioned first blade 4 is made of a plastic blade (PVC plastic material is acceptable) and is used for scraping various algae and scale residues in the fish tank in a short time.

[0052] In addition to the above first structure, the second design structure of the tool is as follows: As Figure 5 、 Figure 6 and Figure 7 shown, the tool includes a second blade 52 and a tool holder 5. One side of the knife groove 27 extends to the side wall of the first housing 2, which is the insertion opening for the tool holder 5 and the second blade 52. The other side wall of the knife groove 27 is provided with a blocking portion 272. One end of the tool holder 5 is the insertion end, and the other end is the external end. And a second limiting piece 55 extends from the side wall of the external end. A matching block 54 is provided on the side wall of the tool holder 5. A jack 53 inserted into the matching block 54 is provided on the side wall of the second blade 52. The insertion end is horizontally inserted into the knife groove 27 along the horizontal insertion opening and fits with the blocking portion 272, and the second limiting piece 55 abuts against the insertion opening position, realizing the stable installation of the second blade 52 in the knife 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 notch of the knife groove 27. The second blade 52 moves along with the first housing 2 on the inner wall of the fish tank, and the cutting edge of the second blade 52 scrapes various algae and scale on the inner wall of the fish tank during the movement.

[0053] A positioning hole 28 is provided on the outer wall of one end of the cutter groove 27 close to the insertion port, and a bump 51 matching the positioning hole 28 is provided on the side wall of one end of the cutter holder 5 close to the second limiting piece 55; at the same time, a positioning hole 271 is provided on the blocking portion 272, and a bump 56 inserted into the positioning hole 271 is provided on the side wall of one end of the cutter holder 5 facing the blocking portion 272. When the second blade 52 and the cutter holder 5 are horizontally inserted into the cutter groove 27, the bump 51 can be snapped into the positioning hole 28, and the bump 56 is inserted into the positioning hole 271. By means of two-point position limiting, the installation stability of the second blade 52 is enhanced, and during the scraping process against the inner wall of the fish tank, the phenomenon of the second blade 52 jumping out of the knife is avoided, resulting in the situation that the inner wall of the fish tank cannot be scraped during the movement, and multiple scraping operations are required, resulting in low cleaning efficiency.

[0054] The above-mentioned second blade 52 is a metal blade (such as a stainless steel blade, with a relatively thin thickness, and a blade with a thickness of 1 mm can be used), which is used for scraping various hard algae and scale residues in the fish tank for a long time. The user can select the above-mentioned first blade 4 or the second blade 52 as the scraping tool according to the usage requirements.

[0055] The specific cleaning process is as follows: When selecting a tool as the cleaning tool, the cleaning side wall is facing the inner wall of the fish tank, and the outer shell 2 can be attached to the inner wall of the fish tank by the external magnet block and the internal magnet block that attract each other. By moving the outer shell 12 on the outside of the fish tank, the outer shell 2 can be driven to move synchronously across the side wall of the fish tank, and then the tool can be driven to move along the inner wall of the fish tank, so as to scrape the various algae and scale residues remaining on the inner wall of the fish tank. When selecting the cleaning cloth 21 as the cleaning tool, the outer shell 2 is turned over, and the outer wall of the cleaning cloth 21 is attached to the inner wall of the fish tank. The outer shell 2 can be attached to the inner wall of the fish tank by the external magnet block and the internal magnet block that attract each other. By moving the outer shell 12 on the outside of the fish tank, the outer shell 2 can be driven to move synchronously across the side wall of the fish tank, and then the cleaning cloth 21 can be driven to move along the inner wall of the fish tank, so as to wipe and clean the inner wall of the fish tank.

[0056] In summary, only by moving the handheld part, the cleaning part can be driven to move synchronously and in the same direction across the side wall of the fish tank. According to the cleaning requirements, the cleaning cloth 21 or the tool is selected to face the inner wall of the fish tank. During the movement of the cleaning part, the inner wall of the fish tank is wiped and cleaned by the cleaning cloth 21 or scraped and cleaned by the tool. It is applicable to fish tanks with large volume and deep depth, and there is no need to hold the cleaning utensils to enter the inner wall of the fish tank for cleaning operations, which improves the cleaning efficiency of the fish tank.

[0057] In order to increase the sealing performance inside the outer shell 2, a Figure 2The rubber washer 24 shown is provided to prevent water from entering the outer shell 2 when it is placed inside the fish tank. If water enters the outer shell 2, it will increase the weight, affecting the resistance of the outer shell 2 to move along the inner wall of the fish tank. At the same time, to prevent water from entering the outer shell 2, which may cause the built-in magnet block to rust and demagnetize, and to ensure that the inside of the outer shell 2 is relatively airtight and has buoyancy, after the outer shell 2 is separated from the outer shell 12, the outer shell 2 can float on the water surface for easy picking up by the user.

[0058] In this embodiment, further, a material leakage notch 210 is provided on the cleaning side wall of the outer shell 2 near the knife groove 27, as Figure 9 shown. No matter which tool is used, during the scraping process, as the blade moves, various algae and scale scraped off will move synchronously with the blade. Then, by adding the material leakage notch 210, various algae and scale can be pushed into the material leakage notch 210 and then exported from the openings on both sides of the material leakage notch 210, preventing a large amount of dirt from accumulating at the edge of the blade and affecting the cleaning efficiency of the blade.

[0059] At the corner position of the cleaning side wall, balls 29 are rotatably embedded. The outer wall of the balls 29 protrudes from the cleaning side wall, as Figure 2 shown. There are four balls 29, distributed at the four corner positions of the cleaning side wall. The outer wall of the balls 29 protruding from the cleaning side wall and the cutting edges of the first blade 4 or the second blade 52 extending out of the knife groove 27 are in the same setting plane. In this way, during the cleaning process, the balls 29 roll and fit against the inner wall of the fish tank, reducing the resistance of the outer shell 2 to translate along the inner wall of the fish tank while ensuring that the cutting edge of the blade can be in seamless contact with the inner wall of the fish tank, achieving the purpose of scraping and cleaning the inner wall of the fish tank.

[0060] Moreover, another advantage of adding the balls 29 is that there is a gap between the cleaning side wall and the inner wall of the fish tank, and the dirt scraped off by the blade is not easy to accumulate on the cleaning side wall, thus preventing a large amount of dirt from accumulating between the cleaning side wall and the inner wall of the fish tank and affecting the cleaning efficiency of the blade. At the same time, the four balls 29 create a gap between the outer shell 2 and the fish tank glass, preventing fine sand and hard scale in the fish tank from staying between the outer shell 2 and the glass and scratching the glass.

[0061] As Figure 8As shown, a T-shaped clamping notch 16 is provided on one of the short side side walls of the outer shell two 12, and a T-shaped holding rod 3 is clamped in the T-shaped clamping notch 16. According to the cleaning requirements, when cleaning the inner side wall of the fish tank against the wall, it is inconvenient for the user to hold the handheld part and move it on the outer wall of the fish tank against the wall. Therefore, the T-shaped holding rod 3 is used to remotely operate the handheld part to move on the outer wall of the fish tank facing the wall, so as to meet the operation requirement of driving the cleaning part to move synchronously on the inner wall of the fish tank for cleaning. In summary, without damaging the overall shape of the product, hidden T-shaped clamping notches 16 are designed on both short side side walls of the outer shell two 12 for splicing with the T-shaped holding rod 3, which is convenient for controlling the outer shell two 12 through the T-shaped holding rod 3 to achieve convenient cleaning of the inner wall of the fish tank against the wall.

[0062] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
