[0002] The breeding of ornamental fish refers to the special breeding and reproduction of fish with ornamental value for ornamental purposes, sales or competitions. When breeding, fish are usually cultured in a fish tank. A fish tank is a transparent container used for raising and displaying fish and other aquatic organisms, usually made of glass or acrylic.

[0003] In the breeding of ornamental fish, a fish tank filter plays a crucial role. It can remove impurities and harmful substances in the water, maintain the cleanliness and stability of the water quality, and provide a healthy living environment for the fish.

[0004] There are some deficiencies in the existing fish tank filters: on the one hand, when replacing the active plate, many filters need to disassemble the entire shell or use special tools to replace it, which is inconvenient to operate. Moreover, during the replacement process, water leakage is likely to occur, increasing the difficulty of maintenance. On the other hand, in terms of stability, the existing filters often lack effective vibration damping measures. When the water pump in the filter works, it will not only generate noise but also may damage the fish tank. Therefore, a novel fish tank filter is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a novel fish tank filter, aiming to improve the problem that the filter in the existing technology needs to disassemble the entire shell or use special tools to replace it.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a new type of fish tank filter, including a housing 1, a water pump 2 is detachably installed on the outer wall of the housing 1. The water pump 2 is a prior art. Water is pumped into the housing 1 from the fish tank through the bottom end of the water pump 2, and then filtered by the active plate 5, and re-enters the fish tank through the drain port on the right side of the housing 1. A damping component 6 is arranged at the bottom end of the outer wall of the housing 1. Two groups of partition plates 3 are fixedly connected to the inner wall of the housing 1. An active plate 5 is detachably installed on the inner wall of the housing 1 through a quick-release component 4. By arranging two groups of stoppers on the surface of the left partition plate 3, two installation spaces for the active plate 5 can be separated in cooperation with the partition plate 3.

[0034] Referring to Figure 2 - Figure 4 , the quick-release component 4 includes a wedge block 41. The wedge block 41 is elastically connected to the inner side wall of the housing 1 through a limiting spring 42. The wedge block 41 is slidably connected to the inner side wall of the housing 1. A notch is formed on the outer wall of the active plate 5. The wedge block 41 is clamped with the inner wall of the notch. The clamping between the two can fix the position of the active plate 5 installed on the inner wall of the housing 1, so as to filter the fish tank water inhaled by the water pump 2. At the same time, the length of the wedge block 41 penetrates through the installation positions of the two groups of active plates 5 that fit. One end of the limiting spring 42 is fixedly connected to the inner side wall of the housing 1, and the other end of the limiting spring 42 is fixedly connected to the outer wall of the wedge block 41. The function of the limiting spring 42 is that when the active plate 5 is installed at the corresponding installation position inside the housing 1, the outer wall of its bottom end will squeeze the arc surface at the top of the wedge block 41, causing the wedge block 41 to move on the inner side wall of the housing 1 until the active plate 5 is completely installed inside the housing 1. The wedge block 41 will be elastically reset by the limiting spring 42 and clamped with the notch of the active plate 5 to fix the installation position of the active plate 5.

[0035] Referring to Figure 4, the inner wall of the bottom end of the housing 1 is elastically connected with a contact plate 44 through a return spring 43. Two groups of stoppers are arranged on the inner side wall of the housing 1. The outer wall of the active plate 5 is in contact with the outer wall of the stopper. By arranging two groups of stoppers, the two groups of active plates 5 can be placed in partitions. One end of the return spring 43 is fixedly connected to the bottom end of the outer wall of the contact plate 44, and the other end of the return spring 43 is fixedly connected to the bottom end of the inner wall of the housing 1. The function of the return spring 43 is that when a new active plate 5 is installed into the inner side of the housing 1 and is fixed by the wedge 41, it will also push the contact plate 44 to descend on the inner wall of the housing 1, so that the return spring 43 is elastically compressed. Until the new active plate 5 pushes the arc surface of the wedge 41 and moves on the inner wall of the housing 1, the contact plate 44 will be elastically acted on by the return spring 43 to automatically push the old active plate 5 outwards, so as to facilitate its replacement. A sealing ring 45 is arranged on the outer wall of the contact plate 44. The contact plate 44 is slidably connected to the inner wall of the bottom end of the housing 1. The outer wall of the sealing ring 45 is in contact with the inner wall of the bottom end of the housing 1. The contact between the two can seal the position of the contact plate 44 through the sealing ring 45, so as to avoid water flowing into the return spring 43 from the gap of the contact plate 44 when used in the housing 1, thereby corroding the return spring 43. The top end of the outer wall of the contact plate 44 is in contact with the bottom end of the outer wall of the active plate 5. The contact between the two makes the active plate 5 push the contact plate 44 to move on the inner wall of the bottom end of the housing 1 when installed inside the housing 1, so that the return spring 43 is elastically compressed.

[0036] Referring to Figure 1 and Figure 5 , the damping assembly 6 includes a mounting plate 61. The surface of the mounting plate 61 is elastically connected with a connecting plate 64 through a connecting spring 65. The mounting plate 61 is fixedly connected to the bottom end of the outer wall of the housing 1. One end of the connecting spring 65 is fixedly connected to the outer wall of the mounting plate 61, and the other end of the connecting spring 65 is fixedly connected to the outer wall of the connecting plate 64. The function of the connecting spring 65 is that when the water pump 2 drives the whole housing 1 to shake during operation, it can be automatically reset through the connecting spring 65. A suction cup 67 is fixedly connected to the left outer wall of the connecting plate 64. The suction cup 67 is a prior art. Through the suction cup 67, the whole can be attached to the outer wall of the fish tank, thereby increasing the overall stability. A sliding sleeve 63 is fixedly connected to the right outer wall of the connecting plate 64. The outer wall of the sliding sleeve 63 is slidably connected with a fixed sleeve 62. The inside of the fixed sleeve 62 is provided with damping liquid, so that when the whole housing 1 shakes, the damping liquid inside it and the connecting spring 65 can be used to slow down the shaking of the whole housing 1, thereby avoiding generating noise. A hinge rod 66 is hinged to the right outer wall of the connecting plate 64. The fixed sleeve 62 is fixedly connected to the outer wall of the mounting plate 61. One end of the hinge rod 66 far from the connecting plate 64 is fixedly connected to the outer wall of the mounting plate 61.

[0037] Working principle: The water pump 2 pumps the water in the fish tank into the interior of the housing 1. After being filtered by the activated plate 5, it re-enters the fish tank from the drain outlet on the right side of the housing 1. When a new activated plate 5 needs to be replaced, when the new activated plate 5 is installed inside the housing 1, it will squeeze the arc surface at the top of the wedge block 41, so that the wedge block 41 moves on the inner wall of the housing 1, thus disengaging from the notch at the current position of the activated plate 5. The contact plate 44 will be elastically acted upon by the return spring 43 to automatically push out the old activated plate 5, facilitating its replacement. At the same time, after the new activated plate 5 descends to the position where the contact plate 44 can move, its notch will be clamped and fixed by the wedge block 41 elastically reset by the limit spring 42.

[0038] On the left outer wall of the connecting plate 64, a suction cup 67 is fixedly connected. The whole is attached to the outer wall of the fish tank through the suction cup 67 to increase the overall stability. On the right outer wall of the connecting plate 64, a sliding sleeve 63 is fixedly connected. The outer wall of the sliding sleeve 63 is slidably connected with a fixed sleeve 62. The fixed sleeve 62 is internally provided with damping fluid. When the whole housing 1 shakes, the damping fluid inside it, combined with the connecting spring 65, can slow down the shaking of the whole housing 1 to avoid generating noise.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
