Description

Technical Field

[0001] The present invention relates to the technical field of fish tanks, and in particular to a food dropping detection system and a fish tank. Background Art

[0002] Nowadays, some miniature aquarium fish tanks on the market are equipped with automatic feeders; users can load a large amount of feed into the automatic feeder in advance, and then remotely issue a "feeding" instruction through a mobile phone APP. The motor of the automatic feeder will run and push the feed into the fish tank. However, in actual use, the automatic feeder may be affected by factors such as foreign object occlusion, mechanical structure jamming, and feed dampening and clotting, resulting in the situation that the automatic feeder may not push the feed into the fish tank after receiving the instruction issued by the mobile phone APP. Due to the current sensing ability of the automatic feeder, neither the underlying software of the automatic feeder nor the mobile phone APP can know that the feed has not been pushed into the fish tank. In this way, without the user's knowledge, the fish being raised are at risk of starving to death. Summary of the Invention

[0003] To solve the above technical problems, the present invention proposes a food dropping detection system and a fish tank, which can detect whether the feed is successfully pushed into the tank body for the user to judge whether the "feeding" instruction is successfully executed.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] In a first aspect, the present invention discloses a food dropping detection system, including a carrier, an automatic feeding device, and a blanking detector. The automatic feeding device includes a housing, a driving member, and a moving block. The driving member and the moving block are respectively arranged inside the housing. The driving member is connected to the moving block and is used to make the moving block extend out of or retract into the housing. The housing is arranged on the carrier; the blanking detector is arranged on the housing or the carrier. The blanking detector is provided with a detection channel and a detection module. The detection side of the detection module faces the detection channel to detect whether the feed passes through; the moving block forms a quantitative bin with a lower opening to accommodate the feed; when the moving block extends out of the housing, the quantitative bin is communicated with the detection channel.

[0006] Preferably, the food dropping detection system further includes a guiding member. The blanking detector is arranged on the guiding member. The guiding member is formed with a guiding channel that penetrates up and down. The guiding channel has an upper opening that is closer to the housing than the detection channel. The lower opening of the guiding channel is communicated with the detection channel.

[0007] Preferably, the lower opening of the guiding channel is smaller than the upper opening of the detection channel and is located in the middle area of the upper opening of the detection channel, and the edge of the lower opening of the guiding channel is vertically offset from the edge of the upper opening of the detection channel.

[0008] Preferably, the blanking detector is arranged below the moving block when the moving block extends out of the housing. When the moving block extends out of the housing, the lower opening of the quantitative bin is exposed above the blanking detector. The detection module is arranged on the side wall of the detection channel. The guiding channel sequentially includes a ramp channel and a vertical channel communicating with each other from top to bottom, and the vertical channel faces the upper opening of the detection channel.

[0009] Preferably, the food falling detection system further includes a waterproof housing, and an installation cavity is arranged in the waterproof housing. The blanking detector is arranged in the installation cavity so as to be surrounded by the waterproof housing at least partially on the circumferential side. A blanking port is arranged below the waterproof housing, and the blanking port is communicated with the detection channel.

[0010] Preferably, the blanking port of the waterproof housing is a bent channel in the vertical direction, and the outlet of the blanking port of the waterproof housing is vertically offset from the detection channel.

[0011] Preferably, the food falling detection system further includes a sliding baffle blocking above the detection channel. In the direction in which the moving block extends out of the housing, the sliding baffle is slidably connected to the waterproof housing and at least partially faces the moving block; when the moving block extends out of the housing, it can push the sliding baffle away from above the detection channel.

[0012] Preferably, a return spring is arranged between the sliding baffle and the inner wall of the waterproof housing to push the sliding baffle back to block above the detection channel when the moving block retracts into the housing.

[0013] Preferably, the detection module includes a transmissive photoelectric sensor, and the transmissive photoelectric sensor includes a laser emitting end and a laser receiving end arranged on opposite side walls of the detection channel; alternatively, the detection module includes a camera arranged on the side wall of the detection channel.

[0014] In a second aspect, the present invention discloses an aquarium, including a tank body and the food falling detection system described in the first aspect, and the bearing member is fixedly connected to the top of the tank body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The disclosed food dropping detection system and fish tank of the present invention are provided with a feeding detector below the moving block protruding from the housing. The feeding detector is provided with a detection channel and a detection module. The detection side of the detection module faces the detection channel to be able to detect whether an object passes through, and thereby judge whether the feed is successfully pushed into the tank body, so that the user can judge whether the "feeding" instruction is successfully executed, thus avoiding the risk of starvation and death of the raised fish.

[0016] In a further aspect, the present invention also has the following beneficial effects:

[0017] (1) A guiding member is further provided between the lower part of the moving block protruding from the housing and the detection channel. A vertically penetrating guiding channel is formed on the guiding member, which can enable the feed dropped from the quantitative bin to pass through the guiding channel and then drop to the detection channel first, avoiding the disordered collision of the feed after dropping from the quantitative bin and polluting the detection module; further, the lower opening of the guiding channel is set to be smaller than the upper opening of the detection channel, and the guiding channel is set as a ramp channel and a vertical channel connected from top to bottom, both of which can further prevent the dropped feed from hitting the detection module.

[0018] (2) The periphery of the feeding detector is wrapped in the installation cavity of the waterproof housing to achieve the side waterproofing of the feeding detector.

[0019] (3) The feeding port of the waterproof housing is set as a bent channel in the vertical direction, which can prevent the water splash from splashing into the detection module from below.

[0020] (4) A movable sliding baffle is further provided above the detection channel to prevent the water splash in the tank from falling onto the detection module from above the detection channel when not working. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0047] As Figure 1As shown, a preferred embodiment of the present invention discloses an aquarium and its food-drop detection system. The aquarium includes a tank body 40 and a top cover 30. The tank body 40 is used to store water to provide a space for fish to move. 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 on the edge of the tank body 40 by opening a slot or other common fixing methods. And a food-drop detection system is fixedly connected to the top cover 30. The food-drop detection system includes a carrier, an automatic feeding device 10, and a feeding detection device 20.

[0048] Combined with Figures 2 to 4 , the automatic feeding device 10 includes a housing 11, a driving member 12, and a moving block 13. The housing 11 is disposed in the top cover 30. The driving member 12 and the moving block 13 are respectively disposed inside the housing 11. The driving member 12 is connected to the moving block 13 and is used to make the moving block 13 extend out of or retract into the housing 11. The feeding detection device 20 includes a feeding detector 21. The feeding detector 21 is disposed below the moving block 13 when the moving block 13 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 the carrier through the housing 11. The feeding detector 21 can be directly or indirectly fixed on the carrier, or can be directly or indirectly fixed on the housing 11. The carrier can be, for example, the top cover 30 of the aquarium, or can also be a detachable bracket fitting fixed on the aquarium, etc.

[0049] The feeding detector 21 is provided with a detection channel 211, and a detection module 212 is provided on the side wall of the detection channel 211. The moving block 13 forms a quantitative bin 131 with an opening at the bottom to accommodate feed. When the moving block 13 extends out of the housing 11, the opening at the bottom of the quantitative bin 131 is exposed above the feeding detector 21 and the quantitative bin 131 is communicated with the detection channel 211, so that the feed in the quantitative bin 131 can fall into the detection channel 211. It should be noted that the feeding detector 21 can also be arranged side by side with the housing 11 in the horizontal direction or form a vertical offset. At this time, the detection channel 211 can be inclinedly communicated with the quantitative bin 131 extending out of the housing 11 in the horizontal direction. At this time, the feed in the quantitative bin 131 falls into the detection channel 211 obliquely. The detection module 212 can also be arranged outside the upper and lower openings of the detection channel 211, and its detection side faces the detection channel to detect whether the feed passes 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 laser; for a camera, its detection side is the side where the lens faces; for an ultrasonic sensor, its detection side is the side that emits sound waves.

[0050] Among them, in one embodiment, the automatic feeding device 10 further includes a storage bin 14, which is arranged above the housing 11 for storing feed. The storage bin 14 can be an integrally formed structure with the housing 11 or separable and detachable from the housing 11. A first discharge opening 141 is formed at the bottom of the storage bin 14. An avoidance opening 111 is formed on the housing 11. A sliding part is provided on the housing 11. The moving block 13 is connected to the sliding part, and the 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 out of or retract into the avoidance opening 111. Specifically, the driving member 12 is, for example, a motor. An output gear 121 is fixed on the output shaft of the motor. A rack 132 is fixed at one 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, and then extend out of or retract into the avoidance opening 111. A quantitative bin 131 is formed through the upper and lower surfaces of the moving block 13. When the moving block 13 retracts into the telescopic opening 111, the top of the quantitative bin 131 is communicated with the first discharge opening 141 at the bottom of the storage bin 14, and the bottom of the quantitative bin 131 is blocked by the sliding part, so that the feed in the storage bin 14 can fall into and be restricted in the quantitative bin 131. The volume of the quantitative bin 131 is fixed, and it can hold a fixed amount of feed each time. When the moving block 13 extends out of the avoidance opening 111, the first discharge opening 141 is blocked by the moving block 13 and cannot discharge materials, while the quantitative bin 131 is exposed above the cylinder body 40 and is directly above the feeding detector 21. At this time, the feed in the quantitative bin 131 will fall into the cylinder body 40 after passing through the detection channel 211, completing the feeding. A cover plate 133 is provided at the outer end of the moving block 13 to block the avoidance opening 111 when the moving block 13 retracts into the avoidance opening 111, preventing water vapor from entering the housing 11 and making the feed in the quantitative bin 131 damp. Further, a sealing ring 1331 surrounding the cover plate 133 can be provided on the side of the cover plate 133 facing the avoidance opening 111 to further improve the moisture-proof performance. The sealing ring 1331 can be, for example, a rubber ring.

[0051] In order to know whether the "feeding" instruction of the automatic feeder is correctly executed, an embodiment of the present application proposes a falling food detection system integrated with a detection module 212. The feeding detector 21 is arranged below the moving block 13 when it extends out of the housing 11, and the detection module 212 is used to detect whether an object passes through to judge whether the feed has successfully fallen. Finally, the detection result of the detection module 212 can be sent to the user's mobile phone through communication methods such as Bluetooth / WiFi for the user to judge whether the "feeding" instruction is successfully executed. The feeding detector 21 can be directly fixedly connected to the top cover 30 or the housing 11.

[0052] The mobile control process of the food dropping detection system is as follows: First, the mobile APP issues a "feeding" instruction, or the automatic feeding device 10 automatically executes the "feeding" instruction according to the preset feeding time; Second, the driving member 12 starts to work, and the moving block 13 extends outwards to push the feed in the quantitative bin 131 into the feed dropping channel; Third, the feed falls under the action of gravity and passes through the detection channel 211; Fourth, the detection module 212 reports the message of "detecting an object passing through" to the electronic circuit control main board, and the electronic circuit control main board forwards this message to the background server and the mobile APP through a wireless communication module such as a wireless WiFi module through a wireless router.

[0053] The blanking detection device 20 further includes a guiding member 221. A vertically penetrating guiding channel 2211 is formed on the guiding member 221. The guiding channel 2211 has an upper opening closer to the housing 11 than the detection channel 211. The lower opening of the guiding channel 2211 is communicated with the detection channel 211. The feed dropped from the quantitative bin 131 can be guided into the detection channel 211 through the guiding channel 2211.

[0054] In one embodiment, the detection module 212 can be a type of 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 provided 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. A detection channel 211 is formed between the two. The feed dropped from the quantitative bin 131 will pass through this detection channel 211, and thus will block the route between the laser emitting end and the laser receiving end. When the laser receiving end cannot receive the laser beam, it indicates that an object has passed through the detection channel 211, and thus it is determined that the feed has dropped. In another embodiment, the detection module 212 includes a camera. The image inside the detection channel 211 can be captured by the camera, and then it is detected whether an object has passed through the detection channel 211 through an image recognition algorithm, and thus it is determined whether there is feed dropping. In other embodiments, the detection module 212 can also include any one of a capacitance sensor, an inductance sensor, an ultrasonic sensor, etc., which can detect whether there is an object passing in front. For example, the capacitance sensor and the inductance sensor can be triggered by the changes in capacitance and inductance caused when the dropped feed passes near the detection module 212, and thus it is determined whether there is feed in the detection channel 211; or the ultrasonic sensor emits ultrasonic waves in the detection channel 211 and measures the reflection time, and determines whether there is an object dropping in the detection channel by calculating the change in the round-trip time of the sound wave.

[0055] As Figures 5 to 10As shown, it is a schematic structural diagram of an aquarium and its food dropping detection system disclosed in a further embodiment of the present invention. In this further embodiment, the feeding detection device 20 includes a feeding detector 21, a housing 22, a sliding baffle 23, and a reset member 24. A detection channel 211 is vertically formed in the feeding detector 21, and a detection module 212 is provided on the side wall of the detection channel 211. The reset member 24 is provided on the housing 22, and the 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, the sliding baffle 23 blocks the upper opening of the detection channel 211. When the sliding baffle 23 is in the second position, the sliding baffle 23 disengages from the upper opening of the detection channel 211. By providing the sliding baffle 23, the waterproof property of the feeding detector 21 can be improved, preventing water in the cylinder body 40 from splashing and sputtering into the detection channel 211 from above the detection channel 211 to contaminate the detection module 212. The upper opening and the lower opening of the detection channel 211 can be respectively formed on the upper end surface and the lower end surface of the feeding detector 21. In some other embodiments, the detection channel 211 can be inclined relative to the vertical direction. Therefore, the upper opening and the lower opening can be on any opposite or non-opposite side surfaces, as long as there is a height difference between the upper opening and the lower opening, and the upper opening is higher than the lower opening, so that the feed entering the upper opening of the detection channel 211 can fall towards the lower opening under the action of gravity.

[0056] As Figure 7 and Figure 8 , a wire passing hole 31 and a threaded hole 32 are formed on the bottom side of the top cover 30 near the avoidance opening 111. Through the wire passing hole 31, the wire in the feeding detection device 20 can penetrate into the top cover 30 to be connected to the PCB control board in the top cover 30. Then, the feeding detection device 20 is fixedly connected to the threaded hole 32 by a screw 201 to fixedly connect the feeding detection device 20 to the top cover 30.

[0057] In this embodiment, the housing 22 includes a guiding member 221 and a waterproof housing 222, which are detachably connected. A mounting cavity is fixedly formed between the guiding member 221 and the waterproof housing 222 to surround the feeding detector 21. A guiding channel 2211 that penetrates up and down is formed on the guiding member 221. The guiding channel 2211 has an upper opening that is closer to the outer shell 11 than the detection channel 211. The lower opening of the guiding channel 2211 is communicated with the detection channel 211. A second feeding port 2221 is provided below the waterproof housing 222, and the second feeding port 2221 is communicated with the detection channel 211. The waterproof housing 222 surrounds the peripheral space of the feeding detector 21 to achieve waterproofing on the side.

[0058] As Figure 11 and Figure 12, the lower opening of the guiding 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 guiding channel 2211 is vertically offset from the edge of the upper opening of the detection channel 211, which can prevent the dropped feed from directly hitting the detection module 212. In this embodiment, the guiding channel 2211 is an overall ramp channel, and the lower opening of the ramp channel is smaller than the upper opening of the detection channel 211. The feed dropped from the metering bin 131 can slide along the ramp channel to the upper part of the detection channel 211 and then drop, avoiding the disordered collision of the feed after dropping from the metering bin 131 and contaminating the detection module 212 on the side wall of the detection channel 211; in another embodiment, the guiding channel 2211 sequentially includes a connected ramp channel and a vertical channel from top to bottom. The vertical channel is directly opposite to 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. At this time, it can further make the feed dropped from the metering bin 131 drop more orderly from the middle position of the detection channel 211.

[0059] In this embodiment, the second material outlet 2221 of the waterproof housing 222 is a bent channel in the vertical direction, which can prevent the water in the cylinder body 40 from splashing onto the detection module 212 from below. Further, the outlet of the second material outlet 2221 of the waterproof housing 222 is vertically offset from the detection channel 211, that is, there is no directly opposite area between the outlet of the second material outlet 2221 of the waterproof housing 222 and the detection channel 211 in the vertical direction.

[0060] In this embodiment, when the sliding baffle 23 is in the first position, it is in a natural state. Among them, in the direction in which the moving block 13 extends out of the housing 11, the sliding baffle 23 is at least partially directly opposite to the moving block 13. When the moving block 13 extends out of the housing 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 housing 11, the sliding baffle 23 is disposed opposite to the cover plate 133 at the outer end of the moving block 13. When the cover plate 133 is driven by the driving member 12 to be pushed out, the cover plate 133 can push the sliding baffle 23 to move. In this embodiment, the reset member 24 is a reset spring, and the reset spring is disposed between the sliding baffle 23 and the inner wall of the waterproof housing 222. When the moving block 13 retracts into the housing 11, the reset spring pushes the sliding baffle 23 from the second position back to the first position in the natural state. In some other embodiments, the reset member 24 can also be 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 housing 222. Among them, 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 close to each other are the same, so as to realize that when the moving block 13 retracts into the housing 11, the sliding baffle 23 is pushed back from the second position to the first position in the natural state due to the repulsive force between the first magnet and the second magnet.

[0061] The sliding baffle 23 includes a first sub-sliding baffle 231 and a second sub-sliding baffle 232 which are connected to each other. The first sub-sliding baffle 231 is located above the guiding channel 2211, and the second sub-sliding baffle 232 is inserted between the guiding 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 guiding 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 respectively disengage from the guiding channel 2211. A slider 233 is further provided on the sliding baffle 23, and a sliding groove 2222 is provided in the waterproof housing 222. The extending direction of the sliding groove 2222 is parallel to the sliding direction of the sliding baffle 23 relative to the housing 22. The slider 233 is slidably connected in the sliding groove 2222, and the reset spring therein can be arranged in the sliding groove 2222 and is located between the slider 233 and the inner wall of the waterproof housing 222 at the end of the sliding groove 2222.

[0062] As Figures 13 to 17 , when the cover plate 133 is driven by the driving member 12 to be pushed out, 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 along the sliding groove 2222 and leave. The first sub-sliding baffle 231 and the second sub-sliding baffle 232 respectively disengage from the guiding channel 2211, that is, the sliding baffle 23 is in the second position. At this time, the guiding channel 2211 is communicated with the detection channel 211, and the feed drops normally.

[0063] As Figure 9 、 Figure 11 and Figure 12 , when the cover plate 133 retracts, the sliding baffle 23 is reset under the action of the reset member 24 and returns to the first position again to block between the guiding 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 guiding channel 2211; in this embodiment, when the sliding baffle 23 is in the first position, the first sub-sliding baffle 231 only blocks a part above the guiding channel 2211, while the second sub-sliding baffle 232 blocks the lower opening of the guiding channel 2211, that is, blocks above the detection channel 211. In other embodiments, when the sliding baffle 23 is in the first position, it is also possible that only the first sub-sliding baffle 231 blocks the upper opening of the guiding channel 2211; or it is also possible to simultaneously let the first sub-sliding baffle 231 block the upper opening of the guiding channel 211 and let the second sub-sliding baffle 232 block the lower opening of the guiding channel 211.

[0064] By setting the sliding baffle 23, it is possible to prevent the water splashes in the cylinder block 40 from falling from above the detection channel 211 into the detection module 212 when not in operation, avoiding the failure or false reporting of the detection module 212.
