Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to the design of a feeding detection device, a feeding detection system, and an aquarium. Background Technology

[0002] Currently, some mini aquariums on the market are equipped with automatic feeders. Users can preload a large amount of food into the feeder and then remotely issue a "feed" command via a mobile app. The feeder's motor will then activate and push the food into the aquarium. However, in actual use, the automatic feeder may be affected by factors such as obstructions from foreign objects, mechanical jamming, or food clumping due to moisture. This can cause the feeder to fail to push the food into the aquarium after receiving the command from the mobile app. Due to the current limitations of the automatic feeder's sensing capabilities, neither the underlying software of the feeder nor the mobile app can detect that the food has not been pushed into the aquarium. Thus, without the user's knowledge, the fish are at risk of starvation and death. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a feeding detection device, a feeding detection system, and a fish tank, which can detect whether the feed has been successfully pushed into the tank so that the user can judge whether the "feeding" command has been successfully executed. On this basis, the waterproof effect of the feeding detector is guaranteed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, this utility model discloses a feeding detection device, including a housing, a feeding detector, a reset member, and a sliding baffle. The feeding detector has a detection channel and a detection module, with the detection side of the detection module facing the detection channel to detect whether feed has passed through. The reset member is disposed on the housing, and the sliding baffle is slidably connected to the housing to move between a first position and a second position. When the sliding baffle is in the first position, it blocks the upper opening of the detection channel; when the sliding baffle is in the second position, it disengages from the upper opening of the detection channel.

[0006] Preferably, the housing includes a guide member, the feeding detector is disposed on the guide member, a guide channel is formed on the guide member that runs vertically through it, the detection channel is located below the guide channel, and the lower opening of the guide channel is connected to the detection channel.

[0007] Preferably, the lower opening of the guide channel is smaller than the upper opening of the detection channel and is located in the middle region of the upper opening of the detection channel, and the edge of the lower opening of the guide channel and the edge of the upper opening of the detection channel are vertically offset from each other.

[0008] Preferably, the guide channel includes, from top to bottom, a connected ramp channel and a vertical channel, the vertical channel being directly opposite the upper opening of the detection channel, the detection channel extending in a vertical direction, and the detection module being disposed on the side wall of the detection channel.

[0009] Preferably, the sliding baffle includes a first sub-sliding baffle and a second sub-sliding baffle, the first sub-sliding baffle being located above the guide channel, and the second sub-sliding baffle being inserted between the guide channel and the detection channel; when the sliding baffle is in the first position, at least one of the first sub-sliding baffle and the second sub-sliding baffle blocks the guide channel; when the sliding baffle is in the second position, the first sub-sliding baffle and the second sub-sliding baffle are respectively disengaged from the guide channel.

[0010] Preferably, the housing includes a waterproof shell, the waterproof shell has an installation cavity, the material discharge detector is disposed in the installation cavity so that it is surrounded by at least part of the peripheral space by the waterproof shell, and the bottom of the waterproof shell has a material discharge port, the material discharge port being connected to the detection channel.

[0011] Preferably, the discharge port of the waterproof shell is a bent channel in the vertical direction, and the outlet of the discharge port of the waterproof shell is staggered from the detection channel in the vertical direction.

[0012] Secondly, this utility model discloses a feeding detection system, including a carrier, an automatic feeding device, and the feeding detection device described in the first aspect. The automatic feeding device includes a housing, a drive member, and a moving block. The drive member and the moving block are respectively disposed within the housing. The drive member is connected to the moving block and is used to extend or retract the moving block from the housing. The housing is disposed on the carrier, and the feeding detection device is disposed on the carrier or the housing. The moving block forms a metering bin with a lower opening to accommodate feed. When the moving block extends from the housing, the lower opening of the metering bin is exposed above the feeding detector, and the metering bin communicates with the detection channel. In the direction in which the moving block extends from the housing, the sliding baffle is at least partially opposite to the moving block. When the moving block extends from the housing, the sliding baffle can be pushed from the first position to the second position.

[0013] Preferably, the reset element is a reset spring, which pushes the sliding baffle back from the second position to the first position when the moving block retracts into the outer shell.

[0014] Thirdly, this utility model discloses a fish tank, including a tank body and the feeding detection system described in the second aspect, wherein the support member is fixedly connected to the top of the tank body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The feeding detection device, feeding detection system and fish tank disclosed in this utility model are provided with a detection channel and a detection module in the feeding detector. The detection side of the detection channel faces the detection channel to detect whether an object passes through, and thereby determine whether the feed has been successfully pushed into the tank. This allows the user to determine whether the "feeding" command has been successfully executed, thereby avoiding the risk of the fish starving to death. In addition, a reset part and a sliding baffle are provided on the shell to block the upper opening of the detection channel, preventing water from the tank from falling into the detection module from above the detection channel when not in operation, thus ensuring the waterproof effect of the feeding detector.

[0016] In a further embodiment, this utility model also has the following beneficial effects:

[0017] (1) The housing includes a guide member, on which a guide channel is formed that runs vertically through the feed. This allows the feed to pass through the guide channel before falling into the detection channel, thus preventing the feed from colliding randomly and contaminating the detection module. Furthermore, the lower opening of the guide channel is made smaller than the upper opening of the detection channel. The guide channel is also made into a ramp channel and a vertical channel that run vertically from top to bottom, which further prevents the falling feed from hitting the detection module.

[0018] (2) The housing includes a waterproof shell, and the periphery of the unloading detector is wrapped in the mounting cavity of the waterproof shell to achieve side waterproofing of the unloading detector.

[0019] (3) The discharge port of the waterproof shell is set as a bent channel in the vertical direction to prevent water from splashing into the detection module from below. Attached Figure Description

[0040] The embodiments of this utility model are described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] like Figure 1 and Figure 2As shown, a preferred embodiment of this utility model discloses a fish tank and its feeding detection system and feeding detection device 20. The fish tank includes a tank body 40 and a top cover 30. The tank body 40 is used to store water to provide space for fish to move around. The top cover 30 is fixedly connected to the top of the tank body 40. The top cover 30 can be used to block or partially block the top of the tank body 40. The top cover 30 can be fixed to the edge of the tank body 40 by opening a slot or other common fixing methods. The feeding detection system is fixedly connected to the top cover 30. The feeding detection system includes a carrier, an automatic feeding device 10 and a feeding detection device 20.

[0045] Combination Figures 3 to 5 The automatic feeding device 10 includes a housing 11, a drive unit 12, and a moving block 13. The housing 11 is located within a top cover 30. The drive unit 12 and the moving block 13 are respectively located within the housing 11. The drive unit 12 connects to the moving block 13 and is used to extend or retract the moving block 13 into the housing 11. The feeding detection device 20 includes a feeding detector 21, a housing 22, a sliding baffle 23, and a reset unit 24. The feeding detector 21 is located below the moving block 13 when it extends out of the housing 11. The feeding detector 21 is fixed relative to the housing 11 and can be directly or indirectly connected to the housing 11. The automatic feeding device 10 is fixed to a support member via the housing 11. The feeding detector 21 can be directly or indirectly fixed to the support member or directly or indirectly fixed to the housing 11. The support member can be, for example, the top cover 30 of the fish tank, or a detachable bracket accessory fixed to the fish tank.

[0046] The feed detector 21 has a detection channel 211 vertically oriented, and a detection module 212 is provided on the side wall of the detection channel 211. A reset member 24 is provided on the housing 22. A sliding baffle 23 is slidably connected to the housing 22 in the horizontal direction to move between a first position and a second position. When the sliding baffle 23 is in the first position, it blocks the upper opening of the detection channel 211. When the sliding baffle 23 is in the second position, it disengages from the upper opening of the detection channel 211. The moving block 13 forms a metering bin 131 with a lower opening to accommodate feed. When the moving block 13 extends out of the housing 11, the lower opening of the metering bin 131 is exposed above the feed detector 21, and the metering bin 131 communicates with the detection channel 211, so that the feed in the metering bin 131 can fall into the detection channel 211. At this time, the sliding baffle 23 is in the second position. It should be noted that the feed detector 21 can also be arranged side-by-side with the housing 11 in the horizontal direction or in a staggered configuration. In this case, the detection channel 211 can be inclinedly connected to the metering bin 131 extending from the housing 11 in the horizontal direction, allowing the feed in the metering bin 131 to fall into the detection channel 211 at an angle. The detection module 212 can also be located outside the upper and lower openings of the detection channel 211, with its detection side facing the detection channel to detect whether feed has passed through. The detection side is the side of the detection module 212 used to interact with the environment to identify environmental changes. For example, for a laser sensor, its detection side is the side that emits the laser; for a camera, its detection side is the side the lens is facing; and for an ultrasonic sensor, its detection side is the side that emits the sound wave.

[0047] By setting the sliding baffle 23, the waterproofness of the feed detector 21 can be improved, preventing water in the cylinder 40 from splashing up and entering the detection channel 211 from above, thus contaminating the detection module 212. The upper and lower openings of the detection channel 211 can be respectively opened on the upper and lower surfaces of the feed detector 21. In some embodiments, the detection channel 211 can be inclined relative to the vertical direction, so the upper and lower openings can be on any opposite or non-opposite side surfaces, as long as there is a height difference between the upper and lower openings, with the upper opening being higher than the lower opening, so that the feed entering the upper opening of the detection channel 211 can fall to the lower opening by gravity.

[0048] In one embodiment, the automatic feeding device 10 further includes a storage bin 14, which is located above the outer casing 11 for storing feed. The storage bin 14 can be integrally formed with the outer casing 11 or can be detached from the outer casing 11. A first discharge port 141 is formed at the bottom of the storage bin 14. An avoidance opening 111 is provided on the outer casing 11, and a sliding part is provided on the outer casing 11. A moving block 13 is connected to the sliding part, and a driving member 12 is connected to the moving block 13 to drive the moving block 13 to move back and forth along the sliding part to extend or retract into the avoidance opening 111. Specifically, the driving member 12 is, for example, a motor, and an output gear 121 is fixed on the output shaft of the motor. A rack 132 is fixed to the end of the moving block 13 away from the avoidance opening 111. The output gear 121 and the rack 132 mesh with each other to drive the moving block 13 to move along the sliding part, thereby extending or retracting into the avoidance opening 111. The upper and lower sides of the movable block 13 form a metering bin 131. When the movable block 13 retracts into the telescopic opening 111, the top of the metering bin 131 is connected to the first discharge port 141 at the bottom of the storage bin 14, and the bottom of the metering bin 131 is blocked by the sliding part, so that the feed in the storage bin 14 can fall into and be confined in the metering bin 131. The volume of the metering bin 131 is fixed, and it can hold a fixed amount of feed each time. When the movable block 13 extends out of the clearance opening 111, the first discharge port 141 is blocked by the movable block 13 and cannot discharge feed. The metering bin 131 is exposed above the cylinder 40 and is located directly above the discharge detector 21. At this time, the feed in the metering bin 131 will fall into the cylinder 40 after passing through the detection channel 211, thus completing the feeding. A cover plate 133 is provided at the outer end of the movable block 13 to seal the relief opening 111 when the movable block 13 retracts into the relief opening 111, so as to prevent moisture from entering the outer shell 11 and making the feed in the metering bin 131 damp; furthermore, a sealing ring 1331 can be provided on the side of the cover plate 133 facing the relief opening 111 to further improve the moisture-proof performance. The sealing ring 1331 can be, for example, a rubber ring.

[0049] To determine whether the "feeding" command of the automatic feeder has been executed correctly, this application proposes a feed detection system integrating a detection module 212. The feed detector 21 is positioned below the movable block 13 when it extends out of the outer casing 11. The detection module 212 detects whether any object passes by to determine if the feed has been successfully dropped. Finally, the detection result from the detection module 212 can be sent to the user's mobile phone via Bluetooth / WiFi or other communication methods, allowing the user to determine whether the "feeding" command was executed successfully. The feed detector 21 can be directly and fixedly connected to the top cover 30 or the outer casing 11.

[0050] The mobile control process of the feeding detection system is as follows: First, the mobile APP issues a "feeding" command, or the automatic feeding device 10 automatically executes the "feeding" command according to the preset feeding time; Second, the drive component 12 starts working, and the moving block 13 extends outward to push the feed in the quantitative bin 131 to the feed drop channel; Third, the feed falls due to gravity and passes through the detection channel 211; Fourth, the detection module 212 reports the message "object detected passing through" to the electronic circuit control motherboard, and the electronic circuit control motherboard forwards this message to the backend server and mobile APP through a wireless router via a wireless communication module such as a wireless WiFi module.

[0051] In one embodiment, the detection module 212 may be an optical detection module. For example, the detection module 212 includes a transmissive photoelectric sensor. The transmissive photoelectric sensor includes a laser emitting end and a laser receiving end disposed on opposite side walls of the detection channel 211. The laser emitting end emits a laser beam, and the laser receiving end receives the laser beam, forming a detection channel 211 between them. Feed falling from the metering bin 131 will pass through this detection channel 211, thus blocking the path between the laser emitting end and the laser receiving end. When the laser receiving end does not receive the laser beam, it indicates that an object has passed through the detection channel 211, thereby determining that feed has fallen. In another embodiment, the detection module 212 includes a camera. The camera can capture images within the detection channel 211, and then an image recognition algorithm can be used to detect whether an object has passed through the detection channel 211, thereby determining whether feed has fallen. In yet another embodiment, the detection module 212 may also include any small sensor capable of detecting whether an object is passing in front of it, such as a capacitive sensor, an inductive sensor, or an ultrasonic sensor. For example, the capacitance and inductance changes caused by the falling feed passing near the detection module 212 can trigger the capacitance sensor and inductance sensor, thereby determining whether feed has fallen into the detection channel 211; or an ultrasonic sensor can emit ultrasonic waves in the detection channel 211 and measure the reflection time, and the change in the round-trip time of the sound wave can be calculated to determine whether an object has fallen into the detection channel.

[0052] like Figure 6 and Figure 7 A wiring hole 31 and a threaded hole 32 are provided on the bottom side of the top cover 30 near the clearance opening 111. The wires in the unloading detection device 20 can be passed through the wiring hole 31 to the top cover 30 to connect to the PCB control board in the top cover 30. Then the unloading detection device 20 is fixedly connected to the threaded hole 32 by screws 201 to fix the unloading detection device 20 to the top cover 30.

[0053] In this embodiment, the housing 22 includes a guide member 221 and a waterproof shell 222, which are detachably connected. The guide member 221 and the waterproof shell 222 are fixedly connected to form an installation cavity that surrounds the feed detector 21. A vertically penetrating guide channel 2211 is formed on the guide member 221. The guide channel 2211 has an upper opening that is closer to the housing 11 than the detection channel 211. The lower opening of the guide channel 2211 is connected to the detection channel 211. Feed falling from the metering bin 131 can be guided into the detection channel 211 through the guide channel 2211. A second feed port 2221 is provided below the waterproof shell 222, which is connected to the detection channel 211. The waterproof shell 222 surrounds the peripheral space of the feed detector 21, achieving side waterproofing.

[0054] like Figures 8 to 10 The lower opening of the guide channel 2211 is smaller than the upper opening of the detection channel 211 and is located in the middle area of ​​the upper opening of the detection channel 211. The edge of the lower opening of the guide channel 2211 and the edge of the upper opening of the detection channel 211 are vertically offset from each other, which can prevent the falling feed from directly hitting the detection module 212. In this embodiment, the guide channel 2211 is generally a ramp channel, and the lower opening of the ramp channel is smaller than the upper opening of the detection channel 211. The feed falling from the metering bin 131 can slide along the ramp channel to the top of the detection channel 211 before falling, avoiding disorderly collisions after the feed falls from the metering bin 131 and contaminating the detection module 212 located on the side wall of the detection channel 211. In another embodiment, the guide channel 2211 includes a ramp channel and a vertical channel connected from top to bottom. The vertical channel is directly opposite the upper opening of the detection channel 211, and the lower opening of the vertical channel is smaller than the upper opening of the detection channel 211. In this case, the feed falling from the metering bin 131 can fall more orderly from the middle position of the detection channel 211.

[0055] In this embodiment, the second discharge port 2221 of the waterproof shell 222 is a bent channel in the vertical direction, which can prevent water in the cylinder 40 from splashing onto the detection module 212 from below. Furthermore, the outlet of the second discharge port 2221 of the waterproof shell 222 is vertically offset from the detection channel 211, that is, there is no area in the vertical direction where the outlet of the second discharge port 2221 of the waterproof shell 222 is directly opposite to the detection channel 211.

[0056] In this embodiment, the sliding baffle 23 is in its natural state when it is in the first position. Specifically, in the direction in which the moving block 13 extends out of the outer shell 11, the sliding baffle 23 and the moving block 13 are at least partially opposite each other. When the moving block 13 extends out of the outer shell 11, it can push the sliding baffle 23 from the first position to the second position. Specifically, in the direction in which the moving block 13 extends out of the outer shell 11, the sliding baffle 23 and the cover plate 133 at the outer end of the moving block 13 are opposite each other. When the cover plate 133 is pushed out by the driving member 12, the cover plate 133 can push the sliding baffle 23 to move. In this embodiment, the reset member 24 is a reset spring, which is disposed between the sliding baffle 23 and the inner wall of the waterproof shell 222. When the moving block 13 retracts into the outer shell 11, the reset spring pushes the sliding baffle 23 from the second position back to the first position in its natural state. In other embodiments, the reset member 24 may also include a first magnet and a second magnet. The first magnet is disposed on the sliding baffle 23, and the second magnet is disposed on the inner wall of the waterproof shell 222. The first magnet and the second magnet are disposed opposite to each other, and the polarities of the sides of the first magnet and the second magnet that are close to each other are the same, so that when the moving block 13 retracts into the shell 11, the repulsive action of the first magnet and the second magnet pushes the sliding baffle 23 from the second position back to the first position in its natural state.

[0057] The sliding baffle 23 includes a first sub-sliding baffle 231 and a second sub-sliding baffle 232 connected to each other. The first sub-sliding baffle 231 is located above the guide channel 2211, and the second sub-sliding baffle 232 is inserted between the guide channel 2211 and the detection channel 211. When the sliding baffle 23 is in the first position, at least one of the first sub-sliding baffle 231 and the second sub-sliding baffle 232 blocks the guide channel 2211; when the sliding baffle 23 is in the second position, the first sub-sliding baffle 231 and the second sub-sliding baffle 232 are respectively disengaged from the guide channel 2211. The sliding baffle 23 is also provided with a slider 233, and the waterproof shell 222 is provided with a groove 2222. The extension direction of the groove 2222 is parallel to the sliding direction of the sliding baffle 23 relative to the shell 22. The slider 233 is slidably connected in the groove 2222. The return spring can be set in the groove 2222 and is located between the slider 233 and the inner wall of the waterproof shell 222 located at the end of the groove 2222.

[0058] like Figures 11 to 15 When the cover plate 133 is pushed out by the drive member 12, the cover plate 133 will push the first sub-sliding baffle 231 to move. At this time, the first sub-sliding baffle 231 and the second sub-sliding baffle 232 will move away along the slide groove 2222. The first sub-sliding baffle 231 and the second sub-sliding baffle 232 will disengage from the guide channel 2211 respectively. That is, the sliding baffle 23 is in the second position. At this time, the guide channel 2211 is connected to the detection channel 211, and the feed falls normally.

[0059] like Figures 8 to 10 When the cover plate 133 retracts, the sliding baffle 23 is reset by the reset member 24, returning to the first position to block between the guide channel 2211 and the detection channel 211. That is, at least one of the first sub-sliding baffle 231 and the second sub-sliding baffle 232 blocks the guide channel 2211. In this embodiment, when the sliding baffle 23 is in the first position, the first sub-sliding baffle 231 only blocks a portion of the upper part of the guide channel 2211, while the second sub-sliding baffle 232 blocks the lower opening of the guide channel 2211, i.e., blocks the upper part of the detection channel 211. In other embodiments, when the sliding baffle 23 is in the first position, only the first sub-sliding baffle 231 may block the upper opening of the guide channel 2211; or the first sub-sliding baffle 231 may block the upper opening of the guide channel 211 and the second sub-sliding baffle 232 may block the lower opening of the guide channel 211 simultaneously.

[0060] By setting the sliding baffle 23, water splashed in the cylinder 40 can be prevented from falling into the detection module 212 from above the detection channel 211 when the cylinder is not in operation, thus avoiding the detection module 212 from malfunctioning or generating false alarms.
