[0031] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] like Figure 1 and Figure 2As shown, the magnetic cleaner of the utility model embodiment includes an inner brush body 1 and an outer brush body 2 magnetically attracted to the inner brush body 1, the inner brush body 1 includes an inner brush body 11, a mounting seat 12, a connecting member 13 and a scraper 14 for scraping impurities from the inner wall of the cylinder body, the inner brush body 11 is provided with a mounting seat 12 on one side along a first direction (the first direction is the X direction shown in the figure), and the mounting seat 12 and the inner brush body 11 are spaced to form a mounting groove 3, the connecting member 13 is inserted in the mounting groove 3, and the end of the connecting member 13 exposed in the mounting groove 3 is connected to the scraper 14. It can be understood that by setting the mounting seat 12 and the inner brush body 1 to form a mounting groove 3 for the connector 13 to plug in, the damage to the structure of the inner brush body 1 is reduced, and the magnetic stability between the inner brush body 1 and the outer brush body 2 is ensured; and the connector 13 provided with a scraper 14 is connected in a detachable manner by plugging into the mounting groove 3, which is convenient for installation and reduces assembly time, and the later disassembly, cleaning or replacement of the scraper 14 is also simple to operate, thereby improving the convenience of using the magnetic cleaner. For example, the connector 13 provided with the scraper 14 is inserted into the mounting groove 3, that is, the connection between the scraper 14 and the inner brush body 1 is completed, and the connection is convenient. Then, the inner brush body 1 provided with the scraper 14 is placed in the fish tank, and the outer brush body 2 is used to magnetically attract the inner brush body 1 to drive the inner brush body 1 to move along the inner wall of the fish tank, so that the scraper 14 cleans the inner wall of the fish tank.

[0033] It should be noted that the mounting seat 12 includes a mounting body 121 and a third connecting portion 122. The mounting body 121 and the inner brush body 1 are spaced apart to form a mounting groove 3. The two ends of the mounting body 121 along the third direction are respectively connected to the inner brush body 1 through a third connecting portion 122 (the third direction is the Y direction shown in the figure). The mounting seat 12 has a simple structure and is easy to produce.

[0034] Optionally, in order to improve the cleaning rate of the fish tank, a detachable thin sponge body can be provided on the side of the inner brush body 1 and the outer brush body 2 adjacent to each other without affecting the magnetic attraction between the inner brush body 1 and the outer brush body 2, so that the inner brush body 1 can further wipe and clean the inner wall of the fish tank while moving, and the outer brush body 2 can wipe and clean the outer wall of the fish tank.

[0035] In this embodiment, if Figure 3As shown, the connecting member 13 includes a first connecting portion 131 and a first body portion 132 and a second body portion 133 arranged at intervals along the first direction. The first body portion 132 and the second body portion 133 are connected through the first connecting portion 131, and the first body portion 132 and the second body portion 133 are spaced to form a first clamping groove 4. The scraper 14 is connected to the second body portion 133, and the first body portion 132 is inserted in the mounting groove 3, and the mounting seat 12 is inserted in the first clamping groove 4. By inserting the first body portion 132 into the mounting groove 3, that is, the first body portion 132 is inserted between the mounting seat 12 and the inner brush body 1, and inserting the mounting seat 12 into the first clamping groove 4, that is, the mounting seat 12 is inserted between the first body portion 132 and the second body portion 133, the connecting member 13 and the mounting seat 12 have a connection relationship of two reverse plugging, which effectively improves the connection stability of the connecting member 13 and the mounting seat 12, thereby ensuring the installation stability of the scraper 14 and reducing the shaking of the scraper 14. Alternatively, if Figure 2 and Figure 3 As shown, a first clamping portion 15 is provided on the inner brush body 11 and at the notch of the mounting groove 3, and the first body portion 132 is clamped with the first clamping portion 15. When the first body portion 132 is inserted into the mounting groove 3, the clamping of the first clamping portion 15 on the first body portion 132 can prevent the first body portion 132 from falling out of the mounting groove 3, thereby ensuring the connection stability between the first body portion 132 and the mounting groove 3 and improving the connection strength between the connecting member 13 and the inner brush body 1.

[0036] Preferably, the first clamping portion 15 also has a guiding slope, which is inclined from an end abutting against the inner brush body 1 toward an end away from the inner brush body 1 and toward the mounting seat 12. Through the setting of the guiding slope, the first main body portion 132 can be guided when the first main body portion 132 is inserted into the mounting groove 3 to avoid the first main body portion 132 being blocked by the first clamping portion 15.

[0037] Of course, in order to further ensure the connection strength between the connecting member 13 and the inner brush body 1, in this embodiment, the size of the first main body portion 132 along the first direction will be slightly larger than the size of the mounting groove 3 along the first direction, that is, the first main body portion 132 and the mounting groove 3 are assembled by interference fit to reduce the shaking between the first main body portion 132 and the groove wall of the mounting groove 3, thereby improving the stability of the connection between the connecting member 13 and the inner brush body 1.

[0038] Furthermore, if Figure 3 and Figure 4As shown, the first body part 132 is recessed with a movable groove 1321 on one side away from the inner brush body 11, and the first body part 132 is also provided with two first cutting grooves 1322 penetrating the first body part 132 on both sides along the first direction, and the first body part 132 has a first side surface 1323 adjacent to the first connecting portion 131 along the second direction (the second direction is the Z direction in the figure), the length of the two first cutting grooves 1322 extends along the second direction and penetrates the first side surface 1323, the two first cutting grooves 1322 are arranged at intervals along the third direction and the first body part 132 is cut to form a second clamping portion 1324, and the second clamping portion 1324 is clamped with the first clamping portion 15. By setting the movable groove 1321, the contact surface between the first body part 132 and the groove wall of the installation groove 3 is reduced, that is, the interference abutment surface between the first body part 132 and the groove wall of the installation groove 3 is reduced, so that the first body part 132 is convenient to be taken out of the installation groove 3 later. In addition, the second clamping portion 1324 is cut out from the middle of the first main body portion 132 by utilizing the two first cutting grooves 1322, and the movable space provided by the movable groove 1321 allows the free end of the second clamping portion 1324 to be moved away from the inner brush body 1 when the first main body portion 132 needs to be taken out from the mounting groove 3, so that the second clamping portion 1324 is disengaged from the abutment with the first clamping portion 15, thereby allowing the first main body portion 132 to be taken out from the mounting groove 3 quickly and conveniently.

[0039] Furthermore, a toggle portion 1325 is provided on the side of the second clamping portion 1324 away from the inner brush body 11, and the toggle portion 1325 at least partially extends along the second direction and protrudes from the first side surface 1323. By providing the toggle portion 1325, the operator only needs to move the raised toggle portion 1325 away from the inner brush body 1 to move the second clamping portion 1324 away from the inner brush body 1, thereby improving the convenience of disassembly of the connecting member 13.

[0040] It should be noted that the first connecting portion 131 is provided at one end of the first main body portion 132 along the second direction. Therefore, in order to provide moving space for the second clamping portion 1324 and the toggle portion 1325, an avoidance groove 1311 is provided on the first connecting portion 131, which is used to provide an avoidance space when the second clamping portion 1324 and the toggle portion 1325 move away from the inner brush body 1, thereby avoiding the second clamping portion 1324 or the toggle portion 1325 from interfering with the first connecting portion 131, making it difficult to remove the first main body portion 132.

[0041] In some embodiments, both sides of the first body portion 132 along the third direction are protrudingly provided with stoppers 1326, and the stoppers 1326 can abut against the mounting seat 12. By setting the stoppers 1326, when the first body portion 132 is inserted into the mounting groove 3, the stoppers 1326 abut against the mounting seat 12, thereby improving the stability of the connection between the connecting member 13 and the mounting groove 3 and reducing the shaking of the connecting member 13. It can be understood that the ideal state of the first body portion 132 being inserted into the mounting groove 3 is that the stoppers 1326 abut against the mounting seat 12, the mounting seat 12 abuts against the first connecting portion 131, and the second clamping portion 1324 abuts against the first clamping portion 15, and the multi-point abutment can effectively ensure the stability of the connection between the connecting member 13 and the mounting seat 12.

[0042] Alternatively, if Figure 2 and Figure 3 As shown, the connecting member 13 further includes a second connecting portion 134, which is connected to the second body portion 133 at an angle, and the inner brush body 1 further includes a fixing seat 5, through which the scraper 14 is connected to the second connecting portion 134. By setting the first connecting portion 131 and the second body portion 133 at an angle, that is, by tilting the second connecting portion 134, the scraper 14 can be tilted along the moving direction, so that the scraper 14 can scrape and clean the inner wall of the fish tank.

[0043] Furthermore, the fixing seat 5 is detachably connected to the second connecting portion 134. The fixing seat 5 is detachably connected to the second connecting portion 134, which facilitates the disassembly and assembly of the fixing seat 5 or the connecting member 13.

[0044] Specifically, Figure 5 and Figure 6 As shown, a connection groove 51 is recessed on the fixing seat 5, and the second connection part 134 is inserted into the connection groove 51. The second connection part 134 is plugged into the connection groove 51 to achieve the installation of the second connection part 134 and the fixing seat 5. The plug-in structure is stable and easy to disassemble. In other embodiments, the second connection part 134 can also be detachably connected to the fixing seat 5 by means of a bolt and a threaded hole, which is not specifically limited here.

[0045] Furthermore, a second engaging groove 1341 is provided on the second connecting portion 134, and a third engaging portion 52 is protrudingly provided on the groove wall of the connecting groove 51, and the third engaging portion 52 is engaged with the second engaging groove 1341. By the engaging arrangement of the third engaging portion 52 with the second engaging groove 1341, the second connecting portion 134 can be prevented from being disengaged from the connecting groove 51, and the connection strength between the fixing seat 5 and the connecting member 13 is improved. In this embodiment, when the third engaging portion 52 is engaged with the second engaging groove 1341, the second connecting portion 134 abuts against the groove bottom of the connecting groove 51, reducing the shaking of the second connecting portion 134 and the fixing seat 5, thereby improving the connection stability between the connecting member 13 and the fixing seat 5, and making the installation of the scraper 14 more reliable.

[0046] Preferably, at least two second cutting grooves 53 communicating with the connecting groove 51 are arranged at intervals on the connecting seat, and the second cutting grooves 53 penetrate the end surface of the fixing seat 5 provided with the notch of the connecting groove 51, and the two adjacent second cutting grooves 53 cut the fixing seat 5 to form a swinging portion 54, and the third clamping portion 52 is arranged on the swinging portion 54. When it is necessary to separate the fixing seat 5 from the second connecting portion 134, the free end of the swinging portion 54 is moved outward to separate the third clamping portion 52 from the second clamping groove 1341. At this time, the second connecting portion 134 is pulled out of the connecting groove 51, and the disassembly of the connecting member 13 and the fixing seat 5 is completed, and the operation is simple.

[0047] Optionally, the scraper 14 is detachably connected to the fixing seat 5, which facilitates the disassembly and assembly of the scraper 14. For example, the fixing seat 5 is provided with a fixing groove on the other end face opposite to the end face provided with the connection groove 51, and the fixing seat 5 is provided with a threaded hole 55 on the other end face opposite to the end face provided with the second cutting groove 53. The scraper 14 is inserted into the fixing groove, and the bolt is screwed through the threaded hole 55 to abut the scraper 14 against the groove wall of the fixing groove to achieve the installation of the scraper 14. The threaded connection is stable and easy to disassemble and assemble. In addition, the scraper 14 of different thickness or different material can be replaced to adapt to the cleaning of different scenes.

[0048] Further, the angle between the second connecting portion 134 and the second body portion 133 is 20°-70°. For example, the angle between the second connecting portion 134 and the second body portion 133 can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65° or 70°, etc. If the angle is too small, the tip of the scraper 14 and the inner wall of the fish tank may be frustrated, causing damage to the tip of the scraper or the inner wall of the fish tank. If the angle is too large, the structural volume of the magnetic cleaner may be increased. The angle of this design is moderate, the scratching is smooth, the scraping effect is good, and the cleaning degree is high.

[0049] Of course, the connector 13 may also include reinforcing ribs, which are used to connect the second body portion 133 and the second connecting portion 134 to enhance the structural stability of the second connecting portion 134. In addition, the second body portion 133 and the second connecting portion 134 may be connected at a point where they are connected by an arc structure to enhance the smoothness of the connection between the second connecting portion 134 and the second body portion 133, enhance the force effect at the connection bend, and facilitate sheet metal bending production.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
