Description

TECHNICAL FIELD

[0001] The utility model relates to fish tank accessory technical field especially, it relates to a fish tank feeding ring for fish tank fixed point feeding. BACKGROUND

[0002] With the improvement of living standards, people start to pursue the quality of spiritual life, more and more families choose to keep pets, such as cats, dogs, tropical ornamental fish etc.For fish, in addition to the fish tank, the most important accessory is the filter system, which is used to filter out harmful substances in the fish tank to purify water quality, making the water clear and transparent, not only can make the fish more healthy, but also can improve the ornamental nature.But, the cause of poor water quality in addition to the normal production of waste, there is an important reason is fish food.Fish generally use automatic feeder to realize fixed point and quantitative automatic feeding, but the fish food particles will be scattered in the water, especially the floating type fish food, more easily follow the water flow full cylinder, the fish food that fish has not eaten will sink to the fish tank everywhere, not easy to clean, thereby polluting the water quality.Therefore, the person who often raises fish will use fish tank feeding ring to enclose the fish food in the fixed position range.

[0003] The fish tank feeding ring of related art includes a food ring that can float on the water surface, a suction cup fixed on the fish tank wall, and a connecting rod connecting the food ring and the suction cup.The connecting rod and the food ring form a hinge, and the suction cup and the connecting rod form a hinge, so that the food ring can rotate up and down relative to the connecting rod, and the connecting rod can rotate up and down relative to the suction cup.On the one hand, the food ring floats on the water surface, and the food ring is fixed to the suction cup through the connecting rod, so that the food ring floats on the water surface at a fixed position and is limited within a fixed horizontal range.On the other hand, beautiful ornamental fish are mostly tropical fish, which need to be heated and kept warm, and the water in the fish tank will evaporate slowly due to heating, especially when it is cold, which is particularly obvious, causing the water level to drop, and the water level drop will make the food ring, which is originally floating on the water surface, suspended on one side of the connecting rod, and the food ring will float out of the food ring from the suspended position after the feeder drops the fish food, causing the phenomenon of full cylinder floating food.The hinge of the suction cup and the connecting rod and the hinge of the food ring and the connecting rod make the connecting rod rotate downward relative to the suction cup under the action of gravity when the water level drops, and the food ring rotates downward relative to the connecting rod, so as to adjust the food ring to always keep floating on the water surface, enclosing the fish food.

[0004] However, in the related aquarium feeders, the hinge structure has a connecting rod with a rotating shaft extending perpendicularly to both ends. Both the suction cup and the feeding ring have matching shaft holes, and the rotating shaft is locked in the shaft hole to achieve the hinge. However, this hinge structure is very small and made of plastic. The smoothness of rotation is not as good as that of a metal structure, and it cannot use lubricating oil. Moreover, the feeding ring is soaked in water for a long time, which causes a thin layer of algae (such as brown algae) to grow at the hinge structure. The algae further increases the resistance when the hinge structure rotates, which can cause it to get stuck and not rotate normally automatically. The reliability is poor, and it is easy to fail to prevent the fish from floating all over the tank. Manual cleaning or even water changes are still required. Furthermore, when the connecting rod rotates from a horizontal to a vertical position, the distance between the feeding ring and the tank wall changes, resulting in a horizontal displacement of the feeding ring on the horizontal plane (within the length range of the connecting rod). This change in the position of the feeding ring affects the fixed-point feeding. To ensure that the feeding ring does not fall out of the ring, the horizontal position of the feeding ring should be as small as possible. For example, in the current technology, the connecting rod is set to be 2-3cm long. However, this limits the applicability of the feeding ring to a water level fluctuation of 2-3cm. In cold weather and under heating conditions, the water level in the aquarium quickly exceeds this range, thus limiting its use.

[0005] Therefore, it is necessary to provide a new aquarium feeder to solve the above-mentioned technical problems. Utility Model Content

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Embodiment one

[0031] Please refer to Figures 1-3 The fish tank feeder 100 provided in the embodiment comprises a fixing device 1, a track 2, a connecting rod 3, a food ring 4 and a power assisting device 5. In the embodiment, the fish tank feeder 100 is a plastic product, which is simple in structure and low in production cost.

[0032] The fixing device 1 is installed and fixed on the back of the track, and is used for fixing the track on the wall of the fish tank. Specifically, the fixing device 1 can be a suction cup or a back adhesive tape. In the embodiment, the fixing device 1 is taken as an example of a suction cup, and two suction cups are arranged along the length direction of the track.

[0033] In the embodiment, two fixing devices 1 are arranged along the length direction of the track 2 to improve the stability of the track 2 fixed on the wall of the fish tank.

[0034] The track 2 comprises a track body 21 in the shape of a column, a channel 22 formed through the track body 21 from one end to the other end, and a sliding groove 23 arranged on one side of the track body 21. The track 2 is generally arranged vertically.

[0035] The sliding groove 23 penetrates the track body 21 along the axial direction of the track body 21 and communicates with the channel 22, and the fixing device 1 is fixed on the opposite side of the track body 21 where the sliding groove 23 is arranged, that is, the sliding groove 23 and the fixing device 1 are arranged on the opposite sides of the track body 21 respectively.

[0036] In the embodiment, the length of the track 2 is 5-10 cm. Generally, when the water level of a household fish tank is reduced by about 5 cm due to evaporation, it will be obviously perceived, so that the water level can be supplemented in time. Therefore, the design length of the track 2 does not need to be too long to meet the use requirement. In special cases, such as when the user is not at home for a period of time, the water level can be reduced more, so the design length of 5-10 cm can meet the requirement. In the embodiment, the cross section of the track 2 is rectangular, specifically, the rectangular shape has an opening shape forming the sliding groove 23. That is, the channel 22 communicates with the outside through the sliding groove 23.

[0037] The connecting rod 3 can float on the water surface, which includes a connecting rod body 31 and a sliding block 32 formed at one end of the connecting rod body 31. The sliding block 32 is accommodated in the channel 22 and its shape matches the cross-sectional shape of the channel 22.

[0038] The size of the sliding block 32 is smaller than the cross-sectional size of the channel 22 and larger than the size of the sliding groove 23. The above structure size design makes the sliding block 32 freely slide up and down in the channel 22 after entering the channel 22 from the top of the track 2, and at the same time makes the sliding block 32 unable to escape through the sliding groove 23 on the water surface plane, effectively realizing the limiting on the horizontal plane, so that the food ring 4 does not move horizontally when floating on the water surface and is in a fixed position, and the distance from the cylinder wall depends on the length of the connecting rod 3. Therefore, the length of the connecting rod 3 is small, such as 0.5-1cm, which can make the distance from the cylinder wall small, facilitate the installation of an automatic feeder on the top of the cylinder wall, and realize real fixed-point feeding, and save materials.

[0039] The width of the connecting rod body 31 is smaller than the width of the sliding groove 23, so that the connecting rod body 31 can extend from the channel 22 to the outside of the track 2 through the sliding groove 23, and be connected to the food ring 4.

[0040] In the embodiment, the connecting rod 3 is made of plastic material, of course, not limited to this, but also can be made of other materials that can float on the water surface. The inside of the connecting rod 3 can be a hollow structure, which is convenient to float on the water surface. Of course, it can also float on the water surface due to the material itself.

[0041] The food ring 4 is annular and can float on the water surface. The connecting rod body 31 and the food ring 4 are located on the same horizontal plane, and the end away from the sliding block 32 is fixed to the outer circumferential side of the food ring 4. In the embodiment, the connecting rod 3 and the food ring 4 are integrally formed of plastic, which is simple to produce and has lower cost. In addition, the connecting rod 3 and the food ring 4 are both hollow structures, which can effectively float on the water surface. The food ring 4 can also have the structure in the prior art, which is provided with a ring of grooves at the bottom, and a ring of buoyancy foams is arranged in the grooves, which is feasible.

[0042] Please refer to Figure 4The structure shown in the figure is a structure schematic diagram of the fish tank food feeding ring of the utility model installed in a fish tank. In the above structure, the fixing device 1 is adsorbed on one tank wall of the fish tank 10, the sliding block 32 of the connecting rod 3 is freely slid up and down in the channel 22 of the track 2, so that the food ring 4 floats on the water surface and synchronously rises or falls with the rising or falling of the water surface, especially when the water level of the fish tank is lowered due to evaporation, the food ring 4 synchronously falls with the connecting rod 3 and the gravity of the food ring 4 itself, so that the food ring 4 is always completely floated on the water surface to ensure that the fish food does not float out of the food ring, and the food ring 4 is always in a fixed position relative to the water surface of the fish tank, so that the effect of the automatic food feeder is better. In the prior art, the hinge adjustment structure, the horizontal position of the food ring changes in a small range during the process of lowering with the water level, that is, the distance between the food ring and the tank wall of the installation fixing device will increase during the process of lowering with the water level, and the distance range of the horizontal movement of the food ring is the length of the connecting rod. Because the size of the track 2 and the channel 22 is much larger than that of the hinge structure in the prior art, the structure design and production are simpler and more convenient, so that the size of the channel 22 can be designed to be larger than that of the sliding block, that is, there is enough sliding space, even if the inner wall of the channel 22 grows a layer of thin algae when the track 2 is soaked in water for a long time, there will be no effective resistance to affect the sliding of the sliding block 32, which greatly improves the reliability of the food ring 4 in automatically adjusting the height in time following the change of the water level, thereby facilitating the control and cleaning of the fish food, prolonging the water change period due to water pollution, saving manpower and water resources, and providing better use experience and simple structure. The food ring 4 also rises with the rising of the water level, which is also the same reason, and more importantly, it effectively solves the smooth problem in the lowering process.

[0043] Of course, in order to make the sliding block 32 smoothly slide in the channel 22, the inner side of the channel 22 can also be designed as a smooth surface, and the outer periphery of the sliding block 32 is designed as a smooth surface.

[0044] More preferably, the fish tank food feeding ring 100 further comprises a power assisting device 5 arranged in the channel 22. The power assisting device 5 connects the sliding block 32 and the track body 21, and generates a pulling force for pulling the sliding block 32 downward in the travel range of the sliding block 32, and the pulling force is smaller than the buoyancy of the water on the food ring 4, thereby further improving the reliability of the food ring 4 in automatically falling with the lowering of the water level, even when the algae in the channel 22 grows more in the extreme case, the food ring 4 can still smoothly fall with the lowering of the water level to keep floating in the same position on the water surface, thereby further improving the reliability and effectively avoiding the phenomenon that the food ring 4 is partially suspended to cause the fish food to scatter.

[0045] In this embodiment, specifically, the assisting device 5 includes a first magnet 51 and a second magnet 52, the first magnet 51 is fixed to the bottom of the sliding block 32, the second magnet 52 is fixed to the bottom of the track body 21, the first magnet 51 and the second magnet 52 are located within the magnetic attraction range of each other, and the maximum mutual magnetic attraction between the first magnet 51 and the second magnet 52 is less than the buoyancy of water to the food ring 4. It should be noted that the first magnet 51 is relatively small with respect to the connecting rod 3 and the food ring 4, and the buoyancy of water still makes the food ring 4 float on the water surface as a whole.

[0046] In this embodiment, the track 2, the connecting rod 3 and the food ring 4 are all made of plastic, and the connecting rod 3 and the food ring 4 can be integrally injection molded.

[0047] Example two

[0048] Please combine Figures 5-6 The structure of this embodiment is basically the same as that of the above-mentioned embodiment one, except that the shape of the track 2' is different, and the structure of the assisting device 5' is different. Specifically, in this embodiment, the cross section of the track 2' is circular or C-shaped with a sliding groove 23' opening, and the fixing device 1' is installed at the position opposite to the opening, and of course, the shape of the sliding block 32' matches it. In addition, the assisting device 5' includes a spring 51', one end of the spring 51' is fixed to the bottom of the track body 21', the other end of the spring 51' is fixed to the bottom of the sliding block 32', so that the spring 51' is in a stretched state in the effective stroke of the sliding block 32', generating a downward pulling force, and the maximum pulling force of the spring 51' is less than the buoyancy of water to the food ring 4', so that the food ring 4' always floats on the water surface, and when the water level drops, it is easier to smoothly and automatically drop to the position, and the reliability is higher.

[0049] In addition to the above-mentioned differences, the other structures are the same as those of embodiment one, and the technical problems and technical effects are also the same, which will not be repeated here.

[0050] Compared with the related art, the fish tank feeding device has the track, the food ring is clamped in the channel of the track through the connecting rod, so that the food ring forms the horizontal plane limiting when floating on the water surface, avoids horizontal movement of the food ring on the water surface, realizes the food ring being held when feeding at the fixed point and not being scattered, meanwhile, the sliding block of the connecting rod freely slides up and down in the channel of the track, so that the food ring floats on the water surface and synchronously rises or falls with the water surface, especially when the water level of the fish tank decreases due to evaporation, the connecting rod and the food ring synchronously decrease through the gravity, so that the food ring always completely floats on the water surface and ensures that the fish food does not come out of the food ring, and the horizontal position of the food ring does not change during the rising and falling process, so that the fixed-point effect is better. The size of the track and the channel is much larger than the hinge structure of the related art, so that the structure design and production are simpler and more convenient, so that the size of the channel can be designed to be larger than the sliding block, so that enough sliding space is left, even if the track is soaked in water for a long time and a layer of water algae grows on the inner wall of the channel, the sliding of the sliding block will not be affected, the reliability of the food ring timely following the water level change and automatically adjusting the height is greatly improved, so that the fish food is conveniently controlled and cleaned, the water changing period due to water pollution is prolonged, and the use experience effect is better.

[0051] The above is only the embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, improvements can be made without departing from the creative concept of the utility model, but these all belong to the protection scope of the utility model.
