Description

Technical Field

[0001] This utility model relates to the field of feeder technology, specifically to a fish tank feeder that adjusts the amount of fish food according to water quality. Background Technology

[0002] In aquaculture or home aquarium keeping, feeders are commonly used equipment. Their core function is to deliver fish food into the water to meet the feeding needs of fish.

[0003] Currently, traditional fish feeders on the market use a direct feeding method. The fish food tends to scatter during the fall, making it difficult to concentrate in a specific area for fish to eat. This also results in a large amount of uneaten fish food being scattered throughout the water. After these uneaten fish food decompose in the water, they can cause large-scale water pollution, leading to local water pollution problems and affecting the aquatic ecosystem and fish health. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fish tank feeder that adjusts the amount of fish food according to water quality, thus solving the technical problem of widespread water pollution caused by the scattered placement of existing feeders.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fish tank feeder that adjusts fish food feeding according to water quality, comprising a feeding tube, which is a hollow structure with openings at both ends. A drive rod that can move up and down is installed inside the feeding tube. A connecting frame is fixedly installed at the bottom of the feeding tube, and a sleeve is fixedly installed at the bottom of the connecting frame. A feeding tray is installed at the bottom of the drive rod. The feeding tray has a shape that contracts at the top and expands downwards at the bottom. The feeding tray is made of a resilient material, and the top of the feeding tray can pass through the sleeve. When the drive rod moves the feeding tray upwards, the feeding tray passes through the sleeve, and the expansion area at the bottom decreases under the action of the inner wall of the sleeve. When the drive rod moves the feeding tray downwards, the expansion area at the bottom of the feeding tray increases due to its own rebound force.

[0006] Furthermore, it also includes a monitoring probe, a cable, and a controller. The monitoring probe is used to monitor the water quality in the feeding area. One end of the cable is connected to the monitoring probe, and the other end of the cable is connected to the controller. The controller is used to receive the water quality monitoring data transmitted by the monitoring probe through the cable.

[0007] Furthermore, the top of the feeding tube has a flared feeding dish, which is connected to the feeding tube.

[0008] Furthermore, a support frame is installed on the top of the feeding tube, and a sleeve is installed on the support frame. The top of the drive rod is installed inside the sleeve.

[0009] Furthermore, a fixing block is fixedly installed on the inner wall of the sleeve, and a sliding groove is opened on the side wall of the drive rod. The fixing block is installed in the sliding groove and cooperates with the sliding groove. The extension direction of the sliding groove is parallel to the axis direction of the drive rod. Through the sliding cooperation between the fixing block and the sliding groove, the drive rod can be prevented from rotating when it moves up and down.

[0010] Furthermore, a threaded rod is provided at the top of the drive rod.

[0011] Furthermore, a nut is installed on the threaded rod via a threaded connection, and the diameter of the nut is larger than the diameter of the sleeve.

[0012] Furthermore, a through-type motor is installed on the sleeve, which is connected to the threaded rod. The through-type motor is electrically connected to the controller, which controls the rotation of the through-type motor.

[0013] Furthermore, a mounting frame is fixedly installed on the top of the feeding tube, and a mounting base is provided on the mounting frame.

[0014] Furthermore, the bottom of the mounting bracket is provided with two downward protruding clamping parts, forming a gap between the two clamping parts. One of the clamping parts is threaded with a set screw, and a stop block is provided at the end of the set screw located between the two clamping parts.

[0015] Compared with the prior art, this utility model provides a fish tank feeder that adjusts the amount of fish food according to water quality, which has the following beneficial effects: This aquarium feeder adjusts the feeding area based on water quality. Through the structural design of the feeding tube, drive rod, connecting frame, sleeve, and feeding tray, particularly the feeding tray's shape (contracting at the top and expanding downwards at the bottom) and its use of a resilient material, the expansion area of ​​the feeding tray's bottom can be flexibly adjusted by the up-and-down movement of the drive rod and the cooperation of the sleeve: when the drive rod moves the feeding tray upwards, the tray's bottom area shrinks due to the inner wall of the sleeve; when the drive rod moves the tray downwards, the tray's bottom area increases due to its own rebound force. During feeding, the fish food falls precisely onto the feeding tray as it falls from the feeding tube. By adjusting the area of ​​the feeding tray, the diffusion range of the fish food can be limited as needed, avoiding the large-scale water pollution caused by scattered fish food in traditional feeders. Furthermore, the feeding area can be flexibly adjusted according to the size of the water body, water quality, number of fish, or changes in the fish's activity area. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model discloses an aquarium feeder that adjusts fish food feeding according to water quality. It includes a feeding cylinder 1, which has a hollow structure with openings at both the top and bottom to form channels for fish food to pass through. Inside the feeding cylinder 1, a drive rod 5 that can move vertically up and down is installed. The drive rod 5 passes through the interior of the feeding cylinder 1 and extends to its lower part.

[0020] A connecting frame 2 is fixedly installed at the bottom of the feeding tube 1, and a sleeve 3 is fixedly installed at the bottom of the connecting frame 2. The sleeve 3 coincides with the central axis of the feeding tube 1. A feeding tray 4 is installed at the bottom of the drive rod 5. The feeding tray 4 is shaped with a tapered top and an expanded bottom, and is made of an elastic and resilient material. The top of the feeding tray 4 passes through the sleeve 3, so that the feeding tray 4 can cooperate with the sleeve 3.

[0021] When the drive rod 5 moves the feeding dish 4 upwards, the feeding dish 4 passes through the sleeve 3 and moves upwards. Under the squeezing action of the inner wall of the sleeve 3, the originally expanded part at the bottom of the feeding dish 4 will contract towards the middle, thus reducing the expansion area at the bottom. When the drive rod 5 moves the feeding dish 4 downwards, the feeding dish 4 gradually breaks free from the constraint of the sleeve 3. At this time, the feeding dish 4 will return to its original shape by its own elastic force, increasing the expansion area at the bottom. Through this structural design, the bottom area of ​​the feeding dish 4 can be flexibly adjusted, adapting to different feeding area requirements based on factors such as water size, water quality, fish population, or fish activity area.

[0022] The top of the feeding tube 1 is provided with a wide-mouthed feeding dish 9, which is connected to the interior of the feeding tube 1. The wide-mouthed feeding dish 9 makes it easier to pour fish food into the feeding tube 1, and the fish food can smoothly enter the interior of the feeding tube 1 through the feeding dish 9 and move along the feeding tube 1.

[0023] A support frame 10 is installed on the top of the feeding tube 1. The support frame 10 can be connected to the feeding tray 9 or the feeding tube 1 to achieve stable support. A sleeve 11 is fixedly installed on the support frame 10. The top of the drive rod 5 is installed inside the sleeve 11. The sleeve 11 guides the up and down movement of the drive rod 5, ensuring that the drive rod 5 maintains a vertical movement trajectory during movement and avoiding deviation or shaking.

[0024] To further enhance the stability of the drive rod 5's movement, a fixing block 12 is fixedly installed on the inner wall of the sleeve 3. Correspondingly, a sliding groove 13 adapted to the fixing block 12 is formed on the side wall of the drive rod 5. The fixing block 12 is embedded in the sliding groove 13, forming a sliding fit structure, and the extension direction of the sliding groove 13 is parallel to the axial direction of the drive rod 5. When the drive rod 5 moves up and down vertically, the fixing block 12 slides synchronously along the trajectory of the sliding groove 13. Through the cooperation of the two, the circumferential rotation of the drive rod 5 can be effectively constrained, preventing the drive rod 5 from tortuously shifting during movement, thus ensuring that the drive rod 5 can only move up and down and cannot rotate.

[0025] The up-and-down adjustment of the drive rod 5 can be achieved through different methods, such as electric drive or manual drive. The electric method can be achieved using an electric telescopic rod. The following two specific embodiments will illustrate the up-and-down adjustment method of the drive rod 5 in detail. Example 1, as Figure 1 and 4As shown, a threaded rod 14 is integrally formed or fixedly connected to the top of the drive rod 5. The threaded rod 14 is coaxially arranged with the drive rod 5, and the outer wall of the threaded rod 14 is machined with external threads. At the same time, a nut 15 is threadedly fitted onto the threaded rod 14. The outer diameter of the nut 15 is larger than the inner diameter of the sleeve 11 on the support frame 10. When it is necessary to adjust the vertical position of the drive rod 5, the user can directly hold the threaded rod 14 or the nut 15 and pull the drive rod 5 upward or press it downward, causing the drive rod 5 to move along the guide direction of the inner wall of the sleeve 11 until the feeding tray 4 is adjusted to the target position (i.e., the bottom expansion area of ​​the feeding tray 4 meets the current feeding needs). After the position of the drive rod 5 is determined, the nut 15 on the threaded rod 14 is turned clockwise, causing the nut 15 to move downward along the external thread of the threaded rod 14 until the bottom surface of the nut 15 is tightly abutted against the top of the sleeve 11. At this point, the downward movement of the drive rod 5 is limited by the clamping action of the nut 15 and the sleeve 11, thus fixing the position of the drive rod 5 and preventing it from shifting downwards due to its own weight or the impact of the fish food during subsequent feeding. This ensures the stability of the position of the feeding tray 4 and the feeding range. If the position of the drive rod 5 needs to be adjusted again, simply turn the nut 15 counterclockwise to release the clamping state between the nut 15 and the sleeve 11, and then repeat the above operation to adjust the height of the drive rod 5.

[0026] Example 2, as Figure 2-3 As shown in Figures 5-6, similar to Embodiment 1, a threaded rod 14 is integrally formed or fixedly connected to the top of the drive rod 5. The threaded rod 14 is coaxially arranged with the drive rod 5, and the outer wall of the threaded rod 14 is machined with a matching external thread. At the same time, a through-type motor 16 is fixedly installed on the sleeve 11 of the support frame 10. The through-type motor 16 has an internal thread structure that matches the threaded rod 14, so that the through-type motor 16 and the threaded rod 14 form a threaded connection. When it is necessary to adjust the height of the drive rod 5, a rotation control signal is sent to the through-type motor 16 through an external control device (such as a controller 8, a switch, etc.): if the through-type motor 16 is controlled to rotate forward, its internal thread will mesh with the external thread of the threaded rod 14, driving the threaded rod 14 to move upward along its own axis, and thus synchronously driving the drive rod 5 to move upward; if the through-type motor 16 is controlled to rotate in reverse, similarly, the threaded rod 14 will move downward along its own axis, and synchronously driving the drive rod 5 to move downward. By controlling the forward and reverse directions and rotation duration of the through-type motor 16, the up and down movement distance of the drive rod 5 can be precisely adjusted, thereby realizing the height of the feeding tray 4 and the area of ​​bottom expansion to meet the feeding range requirements in different scenarios.

[0027] This aquarium feeder adjusts the amount of fish food fed according to water quality, and also includes a monitoring probe 6, a cable 7, and a controller 8 for monitoring water quality. The three together constitute a water quality monitoring system. The water quality monitoring probe 6 needs to be installed in the water area of ​​the feeding area. Its core function is to monitor water quality parameters within the feeding area in real time, such as pH, dissolved oxygen content, ammonia nitrogen concentration, and other key indicators related to fish survival and water quality cleanliness. One end of the cable 7 is fixedly connected to the signal output end of the water quality monitoring probe 6, and the other end is electrically connected to the signal input end of the controller 8, forming a stable signal transmission channel to ensure that the real-time data collected by the water quality monitoring probe 6 can be transmitted to the controller 8 completely and accurately. As the core component for data reception and processing, the controller 8 can store and analyze the water quality monitoring data transmitted by the cable 7 in real time. Users can intuitively view the current water quality status of the feeding area through the display interface of the controller 8. If the monitored water quality parameters exceed the preset safety range, the feeding range of the feeding tray 4 can be adjusted in time (when the feeding range is large, the pollution range of the fish food will expand, and when the feeding range is small, the pollution range of the fish food will shrink), to avoid the impact of water quality deterioration on fish health and further enhance the device's role in protecting the aquatic ecosystem.

[0028] In Example 2 above, the through-type motor 16 can be electrically connected to the controller 8 (e.g., via a wire). When the monitoring probe 6 collects water quality data of the feeding area and transmits it to the controller 8 in real time via the cable 7, the controller 8 analyzes the received water quality data. If water quality parameters (such as increased ammonia nitrogen concentration or decreased dissolved oxygen) are detected, the controller 8 can determine whether to reduce or expand the feeding range based on the water quality data. If the feeding range needs to be reduced, the controller 8 controls the through-type motor 16 to rotate forward, driving the screw and drive rod 5 upward through threaded transmission. This causes the feeding tray 4 to reduce its bottom expansion area under the action of the inner wall of the sleeve 3, thereby reducing the spread of fish food and preventing excess fish food from polluting the water. If the water quality is good and the feeding range needs to be expanded, the controller 8 controls the through-type motor 16 to rotate in reverse, driving the drive rod 5 downward. The feeding tray 4 increases its bottom area by its own rebound force, meeting the needs of fish to disperse and feed.

[0029] A mounting bracket 17 is fixedly installed on the top of the feeding tube 1. The main function of the mounting bracket 17 is to provide fixed support for the feeding tube 1, ensuring that the feeding tube 1 remains stable during use. At the same time, a mounting base 18 is integrally formed or detachably connected to the mounting bracket 17. The structure and size of the mounting base 18 are adapted to common traditional automatic feeders (such as electric feeders) on the market. Traditional automatic feeders can be installed and fixed on the mounting base 18, realizing the combined use of this device and traditional automatic feeders.

[0030] The bottom of the mounting bracket 17 has two downward-protruding clamping portions 19, which are arranged opposite each other and form a certain gap between them. One of the clamping portions 19 has a threaded hole, through which a set screw 20 is threadedly connected to the clamping portion 19. A stop block 21 is fixedly installed at the end of the set screw 20 that extends between the two clamping portions 19. When it is necessary to fix the component, the component is placed in the gap between the two clamping portions 19, and the set screw 20 is turned to move the stop block 21 toward the other clamping portion 19 until the stop block 21 is tightly abutting against the component. The clamping and fixing of the component is achieved through the cooperation of the stop block 21 and the other clamping portion 19, thereby improving the stability of the connection between the mounting bracket 17 and the component.

[0031] A suction cup 22 is fixedly installed on the monitoring probe 6. The suction cup 22 can be directly attached to the inner wall of the fish tank or fish pond for fixed installation of the monitoring probe 6.

[0032] In summary, this aquarium feeder, which adjusts fish food feeding according to water quality, requires staff to first check the water quality monitoring data displayed on the controller 8. The water quality data is transmitted from the water quality monitoring probe 6, allowing for a direct understanding of the current water quality status of the aquarium or pond.

[0033] Subsequently, the staff adjusted the up and down position of the drive rod 5 according to the water quality: if the water quality was good, the drive rod 5 could be moved up and down manually or electrically (such as by turning the nut 15 on the threaded rod 14 or controlling the through motor 16); if the water quality was good, the drive rod 5 would be moved down to increase the expansion area at the bottom of the feeding plate 4; if the water quality was poor, the drive rod 5 would be moved up to reduce the expansion area at the bottom of the feeding plate 4.

[0034] After the area of ​​the feeding tray 4 is adjusted, the staff pours the fish food into the feeding tray 9 at the top of the feeding cylinder 1. The fish food falls down along the hollow channel of the feeding cylinder 1 and finally lands on the feeding tray 4. The fish can concentrate on feeding in the area of ​​the feeding tray 4. By adjusting the area of ​​the feeding tray 4 as needed, the feeding needs of the fish can be met while avoiding excessive pollution of the water by the fish food.
