Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0028] like Figure 1 As shown, a preferred embodiment of the present invention discloses a fish tank and an automatic feeder thereof. The fish tank includes a tank body 10 and a top cover 20 . The top cover 20 is fixedly connected to the top of the tank body 10 , and the automatic feeder 30 is fixedly connected to the top cover 20 .

[0029] Combine Figures 2 to 4 The automatic feeder 30 includes a storage bin 31, a shell 32, a driving member 33, a moving block 34 and a spring 35. The storage bin 31, the driving member 33 and the moving block 34 are respectively arranged in the shell 32. The shell 32 is provided with an avoidance opening 322. The storage bin 31 is located above the moving block 34. The storage bin 31 can be an integrally formed structure with the shell 32, or can be detachable from the shell 32. A sliding portion 321 is provided on the shell 32, and the moving block 34 is connected to the sliding portion 321, and the driving member 33 is connected to the moving block 34. It is used to drive the moving block 34 to move back and forth along the sliding portion 321 to extend or retract the avoidance opening 322; the upper and lower surfaces of the moving block 34 are penetrated to form a quantitative bin 341, and the spring piece 35 is provided on the moving block 34 and is located above the quantitative bin 341, and at least part of the spring piece 35 is tilted toward the side close to the storage bin 31. When the moving block 34 is retracted into the avoidance opening 322, the upper opening of the quantitative bin 341 is connected to the bottom of the storage bin 31 and the tilted part of the spring piece 35 extends into the storage bin 31, and the lower opening of the quantitative bin 341 is blocked.

[0030] By arranging the spring piece 35 on the moving block 34 and above the quantitative bin 341, and at least a portion of the spring piece 35 is tilted toward the side close to the storage bin 31; when the quantitative bin 341 is opposite to the bottom of the storage bin 31, the portion of the spring piece 35 tilted toward the side close to the storage bin 31 can extend into the storage bin 31; further, when the moving block 34 moves back and forth in the sliding portion 321, the tilted portion of the spring piece 35 can slide the feed in the storage bin 31, making it easier for it to fall into the quantitative bin 341, thereby effectively avoiding the problem of the feed being unable to fall due to moisture and sticking.

[0031] The top of the moving block 34 forms a fixed groove 342 at the edge of the upper opening of the quantitative bin 341, and the spring piece 35 is fixed in the fixed groove 342; specifically, the upper surface of the spring piece 35 in the fixed groove 342 is flush with the upper surface of the moving block 34, and the upper surface of the moving block 34 is against the bottom of the storage bin 31. In one embodiment, the spring piece 35 is an elongated structure, and the top of the moving block 34 is provided with a fixed groove 342 at two opposite edges of the upper opening of the quantitative bin 341. The two ends of the spring piece 35 are respectively fixed in the two fixed grooves 342, and the middle part of the spring piece 35 is tilted toward the side close to the storage bin 31. Furthermore, the two fixed grooves 342 are relatively opened along the moving direction of the moving block 34. During the process of the moving block extending out of the avoidance opening 322, the raised portion of the spring clip 35 (i.e., the middle portion of the spring clip 35) is held by the bottom edge of the storage bin 31 and deformed toward the metering bin 341, so that the spring clip 35 can smoothly extend along with the moving block 34. In another embodiment, the spring clip 35 is in the form of an elongated strip, with the first end of the spring clip 35 fixed in the fixing groove 342, and the second end of the spring clip 35 suspended above the metering bin 341 and raised toward the side close to the storage bin 31. Furthermore, the fixing groove 342 is provided at the edge of the upper opening of the metering bin 341 close to the avoidance opening 322, so that the spring clip 35 extends backward from the fixing groove 342, and the direction indicated by the backward is opposite to the direction of movement of the moving block 34 when it extends out of the avoidance opening 322. With such arrangement, in the process of the moving block 34 extending out of the avoidance opening 322, the raised part of the spring piece 35 (i.e., the end of the spring piece 35) can be more easily supported by the bottom edge of the storage bin 31 and deformed toward the quantitative bin 341, so that the spring piece 35 can smoothly follow the moving block 34 to extend out.

[0032] In a preferred embodiment, the length direction of the spring piece 35 with a long strip structure is arranged along the moving direction of the moving block 34, so that it can further facilitate the raised part of the spring piece 35 to be supported by the bottom edge of the storage bin 31 and deformed toward the quantitative bin 341 during the process of the moving block 34 extending out of the avoidance opening 322.

[0033] The width of the spring piece 35 in the direction perpendicular to the length of the strip-shaped spring piece 35 is less than 1 / 3 of the width of the quantitative bin 341 to avoid excessive covering of the upper opening of the quantitative bin 341 and causing the feed to fall.

[0034] The spring piece 35 can be made of metal or plastic, for example. In one embodiment, the spring piece 35 is a boss spring piece with flat sides and a raised structure in the middle. The two ends of the boss spring piece are fixed in the fixing groove 342, and the raised part is located directly above the quantitative bin 341 and faces the storage bin 31.

[0035] In other embodiments, the spring piece 35 may also be fixed on the side wall of the quantitative chamber 341 , that is, the fixing groove 342 may be opened on the side wall of the quantitative chamber 341 .

[0036] In other embodiments, the spring piece 35 can also be a flat plate structure with a hollow center and a raised portion in the middle of the hollow portion. The flat plate structure as a whole covers the top surface of the moving block 34, so that there is no need to set a fixing groove 342 above the moving block 34.

[0037] The automatic feeder 30 further includes a rotating plate 36, which is rotatably connected to the bottom of the moving block 34, so that when the moving block 34 retracts into the avoidance opening 322, the rotating plate 36 abuts against and closes the lower opening of the quantitative chamber 341; when the moving block 34 extends to the avoidance opening 322, the rotating plate 36 rotates and falls to open the lower opening of the quantitative chamber 341. Figure 5 and Figure 6 As shown, a cover plate 344 is provided at the outer end of the movable block 34. This is used to block the escape opening 322 when the movable block 34 is retracted into the escape opening 322, preventing moisture from entering the housing 32 through the escape opening 322 and dampening the feed in the metering chamber 341. A sealing ring 3441 is provided on the side of the cover plate 344 facing the escape opening 322, surrounding the movable block 34. When the movable block 34 is retracted into the escape opening 322, the sealing ring 3441 abuts against the escape opening 322 to block the escape opening 322, further improving moisture-proof performance. For example, the sealing ring 3441 is a rubber ring.

[0038] In this embodiment, the sliding portion 321 is a slot defined in the housing 32, within which the moving block 34 is restrained. A rack 343 is secured to the end of the moving block 34 facing away from the escape opening 322. An output gear 331 is secured to the output shaft of the driver 33. The output gear 331 and rack 343 mesh with each other to drive the moving block 34 along the slot, thereby extending or retracting the telescopic buckle 322. Both the output gear 331 and rack 343 are contained within the slot.
