[0002] Bird feeders are devices designed for wild birds to provide food in outdoor environments such as yards or parks. These devices are commonly found in hanging or standing structures, usually filled with a variety of seeds, grains or nuts, attracting a variety of birds to come and feed. By observing the natural behavior and beautiful feathers of birds, people can enjoy the pleasure of being close to nature while providing the birds with necessary food support.

[0003] Although bird feeders have the advantage of attracting and supporting birds, they often face interference from small animals such as squirrels during actual use. Squirrels are attracted to the food in the bird feeder, use their excellent climbing and jumping abilities to approach the feeding point, and consume a large amount of food originally prepared for birds. This interference not only affects the food supply of birds, but may also cause birds to avoid the feeding point, thereby reducing the effectiveness of the bird feeder.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] The terms "first" and "second" in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps, operations, components or modules is not limited to the listed steps, operations, components or modules, but may optionally include steps, operations, components or modules that are not listed, or may optionally include other steps, operations, components or modules that are inherent to these processes, methods, products or devices.

[0052] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] Embodiment 1 like Figures 1 to 16 As shown, an exemplary embodiment of a bird feeder for driving away squirrels by spraying pheromone repellents includes a bird feeder body 1, a spraying mechanism 2 for spraying the pheromone repellent, and an identification device 3 for identifying squirrels; the spraying mechanism 2 is used to spray the pheromone repellent for driving away squirrels, and when the identification device 3 identifies the squirrel, the spraying mechanism 2 sprays the pheromone repellent to drive away the squirrel.

[0054] In actual use, the bird feeder body 1 is installed at a suitable place for feeding, such as a building or a tree trunk. This is to facilitate birds to eat and people to watch. When a squirrel tries to reach the bird feeder and grab the bird food, the identification device 3 will identify the squirrel, and after confirming that the target is a squirrel, the spraying mechanism 2 is controlled to spray pheromone repellent to drive the squirrel away and prevent the squirrel from grabbing the bird food.

[0055] Pheromone repellent specifically refers to a compound designed to repel squirrels, which simulates natural pheromones that may make squirrels feel uncomfortable or threatened. These pheromones can be the smell of natural enemies or other environmental signals that squirrels consider to be unfavorable or dangerous. In this embodiment, the mechanism of action of the pheromone repellent is based on the olfactory sensitivity of squirrels, and by releasing specific chemical signals, squirrels' escape response is stimulated, thereby effectively preventing them from entering and staying in the bird feeder area. This repellent is usually highly selective, meaning that it is mainly effective against target animals (such as squirrels) and has minimal interference with other animals (such as birds).

[0056] The pheromone can be, but is not limited to, chili powder, chili oil, mint oil, urea products, onion extract, garlic extract or citrus oil.

[0057] The identification device 3 comprises: Infrared sensor 31: used to continuously monitor moving heat sources in the food tray area, such as small animals such as squirrels. This sensor detects infrared radiation generated by body temperature to achieve instant detection of animals and improve recognition efficiency. Specifically, a PIR (passive infrared) mobile monitoring sensor is used, which can respond quickly when an animal enters the monitoring area.

[0058] Camera 32: works in conjunction with the infrared sensor 31. When the infrared sensor 31 detects a moving heat source, the camera 32 automatically starts to capture and record real-time images in the area to achieve visual recognition function.

[0059] Image transmission module 33: responsible for transmitting the images captured by camera 32 to the server backend in real time. This module ensures the fast and safe transmission of image data, which facilitates further analysis by the server backend.

[0060] Server backend: Equipped with an AI algorithm model optimized for the smart bird feeder scenario, it specifically analyzes the image data sent by the image transmission module 33 and can accurately identify squirrels in the image. The AI ​​model is specially designed to improve recognition accuracy and reduce false alarms, ensuring that the repelling mechanism is only activated when a squirrel is confirmed to be detected.

[0061] Control module 34: Based on the analysis result of the server background, once it is confirmed that there are squirrels in the image, control module 34 will automatically start the spraying mechanism 2 of the bird feeder to spray pheromone repellent, thereby effectively driving away the squirrels.

[0062] Furthermore, the main responsibility of the server backend is to receive, process and analyze data from the identification device 3 (such as the camera 32 and the infrared sensor 31). Through the image transmission module 33, the server backend receives the real-time image data captured by the bird feeder camera 32, and may also receive the motion data provided by the infrared sensor 31. The server backend is equipped with an artificial intelligence (AI) model optimized for identifying squirrels and other possible intrusive animals. The model uses deep learning technology and is trained on a wide range of animal image data sets to distinguish between squirrels, birds and other animals. The AI ​​model is designed with special emphasis on improving the accuracy of recognition and reducing the possibility of false positives and false negatives.

[0063] After receiving the image data, the AI ​​model will analyze the content in the image, such as the shape, size and movement pattern of the animal, to determine whether there is a squirrel in the image. Once the AI ​​model confirms that there is indeed a squirrel in the image, the server backend sends a signal to the control module 34 of the bird feeder, instructing it to activate the spraying mechanism 2. After receiving the signal, the spraying mechanism 2 will spray the pheromone repellent according to the preset program.

[0064] The server background also includes the function of maintaining and updating the AI ​​model. By continuously collecting feedback data during use, iterative optimization of the AI ​​model is performed to improve its adaptability and overall recognition accuracy.

[0065] Specifically, the spraying mechanism 2 includes a conveying device 21, a spraying pipeline 22 and a storage tank 24. The spraying pipeline 22 is connected to at least one nozzle 23. The input end of the spraying pipeline 22 is connected to the output end of the conveying device 21. The input end of the conveying device 21 is connected to the storage tank 24. The storage tank 24 stores pheromone repellent. By controlling the conveying device 21, the conveying device 21 sucks the pheromone repellent in the storage tank 24 into the interior and conveys it to the spraying pipeline 22. The pheromone repellent is transmitted to the nozzle 23 through the spraying pipeline 22 and sprayed out by the nozzle 23 to drive away squirrels.

[0066] Specifically, the conveying device 21 is a pump.

[0067] Specifically, there are two nozzles 23, both of which are connected to the spraying pipeline 22, and the two nozzles 23 are arranged in a Y shape. Two nozzles 23 arranged in a Y shape are provided. During use, the pheromone repellent in the spraying pipeline 22 enters the two nozzles 23 and is sprayed out by the two nozzles 23. The Y-shaped arrangement of the nozzles 23 makes the sprayed pheromone repellent divergent, so that the coverage of the pheromone repellent is wider, thereby improving the squirrel repelling effect.

[0068] Embodiment 2 During the pheromone spraying process, bird food may be contaminated. To avoid this, Figures 2 to 6 As shown, the present embodiment is different from the first embodiment in that the present embodiment further comprises a shielding mechanism 4 for shielding the bird food in the bird feeder body 1, and the shielding mechanism 4 shields the bird food in the bird feeder body 1 before the spraying mechanism 2 sprays the pheromone repellent, thereby preventing the sprayed pheromone from contaminating the bird food.

[0069] Specifically, the shielding mechanism 4 includes a first baffle 41 and a lifting mechanism 42; the first baffle 41 is connected to the lifting mechanism 42, and the lifting mechanism 42 is used to drive the first baffle 41 to perform lifting movement. When the first baffle (41) rises, the bird food in the bird feeder body 1 is shielded to prevent the sprayed pheromone repellent from contaminating the bird food. In actual use, the first baffle 41 is controlled to move upward by the lifting mechanism 42. After the first baffle 41 is extended, Figure 2 As shown, the first baffle 41 shields the bird food.

[0070] Specifically, the lifting mechanism 42 includes two inner sleeves 421, two outer sleeves 422, two screws 423, a transmission assembly 424 and a drive assembly 44; the two outer sleeves 422 are connected to the bird feeder body 1, the two inner sleeves 421 are respectively slidably installed in the two outer sleeves 422, the first baffle 41 is connected between the two inner sleeves 421, the two screws 44 are respectively rotatably installed in the two outer sleeves 422, the two screws 44 are respectively threadedly connected to the two inner sleeves 421, the lower ends of the two screws 44 extend out of the outer sleeves 422 and are connected to the transmission assembly 424, the drive assembly 44 is connected to the transmission assembly 424, and the drive assembly 44 drives the two screws 423 to rotate synchronously through the transmission assembly 424. The driving assembly 44 drives the two screw rods 423 to rotate through the transmission assembly 424. The two screw rods 423 rotate synchronously. The rotation of the two screw rods 423 drives the two inner sleeves 421 to rotate. The two inner sleeves 421 perform telescopic movement relative to the outer sleeve 422. When the two inner sleeves 421 extend relative to the two outer sleeves 422, the two inner sleeves 421 drive the first baffle 41 to move upward, prompting the first baffle 41 to block the bird food.

[0071] Specifically, the sides of the two outer sleeves 422 are respectively provided with strip notches 4221 for the first baffle 41 to slide. With this structural design, when the two inner sleeves 421 are retracted into the outer sleeves 422, the strip notches 4221 provide space for the movement of the first baffle 41, ensuring the movement of the first baffle 41. At the same time, when the two inner sleeves 421 are retracted into the outer sleeves 422, the first baffle 41 is located between the two outer sleeves 422, and the structure is compact.

[0072] Specifically, the transmission assembly 424 includes two active bevel gears 4241, two driven bevel gears 4242 and a transmission shaft 4243; the two driven bevel gears 4242 are respectively connected to the lower ends of the two screw rods 44, the two active bevel gears 4241 are respectively connected to the transmission shaft 4243, the two active bevel gears 4241 are respectively meshed and connected with the two driven bevel gears 4242, and the driving assembly 44 is connected to the transmission shaft 4243 to drive the transmission shaft 4243 to rotate. When the driving assembly 44 drives the transmission shaft 4243, the transmission shaft 4243 drives the two active bevel gears 4241 to rotate, the two active bevel gears 4241 drive the two driven bevel gears 4242 to rotate, and the two driven bevel gears 4242 drive the two screw rods 44 to rotate. Since the power of the two driven bevel gears 4242 comes from the transmission shaft 4243, the two driven bevel gears 4242 rotate synchronously, thereby causing the two screw rods 44 to rotate synchronously.

[0073] Specifically, the driving assembly 44 includes a first motor 441, a worm wheel 442 and a worm 443. The first motor 441 is connected to the worm 443. The transmission shaft 4243 passes through the worm wheel 442 and is fixedly connected to the worm wheel 442. The worm wheel 442 is meshed and connected with the worm 443. When the first motor 441 is started, the output end of the first motor 441 drives the worm 443 to rotate, the worm 443 drives the worm wheel 442 to rotate, and the worm wheel 442 directly drives the transmission shaft 4243 to rotate, thereby realizing the driving of the transmission shaft 4243.

[0074] like Fig.13 As shown, in order to ensure stable transmission between the transmission shaft 4243, the active bevel gear 4241 and the driven bevel gear 4242, a mounting cavity 4244 is further provided outside the transmission shaft 4243. The lower end of the screw 44 extends into the mounting cavity 4244 and is rotatably connected to the top wall of the mounting cavity 4244.

[0075] Embodiment 3 Compared with the second embodiment, the present embodiment is different in that the spraying mechanism 2 further includes a swinging assembly 25, and the swinging assembly 25 is used to drive the spraying pipeline 22 to move so that the spray head 23 performs a swinging motion.

[0076] like Figure 7As shown, the swing assembly 25 includes a sleeve 251 and a rotating arm 252, the sleeve 251 is rotatably connected to the rotating arm 252, one end of the sleeve 251 away from the rotating arm 252 is connected to the worm 443, the sleeve 251 is sleeved on the spraying pipeline 22 and is slidably connected to the spraying pipeline 22; the spraying pipeline 22 is connected to a seat bearing 223; the spraying pipeline 22 is rotatably connected to the output end of the conveying device 21; The cross-sections of the outer sleeve 422 and the inner sleeve 421 are quadrilaterals. The screw 423 includes a threaded portion 4231 and a guide portion 4232. The guide portion 4232 extends into the inner sleeve 421. A limiting portion 4221 is provided at the top of the outer sleeve 422, and a limiting seat 4211 is provided at the bottom of the inner sleeve 421.

[0077] Specifically, the input end of the spraying pipeline 22 is rotatably connected to a connecting pipe 221, a first limiting clamp ring 222 is arranged in the connecting pipe 221, the input end of the spraying pipeline 22 extends into the connecting pipe 221, and a second limiting clamp ring 224 matching the first limiting clamp ring 222 is arranged at the input end of the spraying pipeline 22, and one end of the connecting pipe 221 away from the spraying pipeline 22 is connected to the output end of the conveying equipment 21.

[0078] In order to make the coverage of the pheromone repellent wider, in this embodiment, while spraying the pheromone repellent, the nozzle 23 is swung to make the coverage of the pheromone repellent wider and increase the range of squirrels.

[0079] Furthermore, the first motor 441 drives the rotating arm 252 to rotate through the worm 443, and the rotating arm 252 drives the sleeve 251 to perform circular motion. The rotation of the sleeve 251 drives the spraying pipeline 22 to swing, causing the nozzle 23 to swing, thereby increasing the spraying range of the pheromone repellent.

[0080] During the swinging process of the spraying pipe 22, the spraying pipe 22 rotates relative to the connecting pipe 221. Due to the cooperation between the first limit collar 222 and the second limit collar 224, the spraying pipe 22 is prevented from falling off relative to the connecting pipe 221. The setting of the seat bearing 223 provides a support point for the movement of the spraying pipe 22 with the seat bearing 223 as the center, so that the movement of the spraying pipe 22 takes the seat bearing 223 as the center, thereby improving the stability of the swinging of the spraying pipe 22. Fig.12 As shown, the seat bearing 223 is connected to the installation cavity 28 through a plate-shaped connecting piece to ensure stable installation of the seat bearing 223.

[0081] In actual use, since the spraying pipeline 22 needs to perform a reciprocating swinging motion, and the rotation of the worm 443 will indirectly drive the two screws 423 to rotate, the screw 423 is provided with a threaded portion 4231 and a guide portion 4232. When the screw 423 rotates continuously to make the inner sleeve 421 rise continuously, the threaded connection between the inner sleeve 421 and the threaded portion 4231 of the screw 423 is cancelled. At this time, due to the action of the limiting portion 4221 and the limiting seat 4211, the inner sleeve 421 will not be separated from the outer sleeve 422. At the same time, the guide portion 4232 maintains an active connection relationship with the inner sleeve 421. Due to the action of the threaded portion 4231 of the screw 423, the inner sleeve 421 can produce a small movement. When the first motor 441 reverses, the screw 423 also reverses, and under the action of gravity, the two inner sleeves 421 are threadedly connected to the two screws 423 again, and then the inner sleeves 421 descend under the action of the threads, and finally the first baffle 41 is retracted. The shielding of the bird feeding area 16 is cancelled.

[0082] This embodiment uses the same motor (first motor 441) to drive the first baffle 41 and the swing assembly 25 to reduce the complexity of the system. This design simplifies the mechanical structure and reduces the number of independent components that must be integrated, thereby reducing the probability of errors in the design process and the risk of system failure. The linkage operation of the first baffle 41 and the swing assembly 25 ensures the synchronization and coordination of the operation, which is crucial to the overall performance and effect of the system. For example, when a squirrel is identified and needs to be expelled, the baffle is raised and the pheromone spraying is started at the same time, which can more effectively prevent the squirrel from approaching the bird food. The linkage also ensures the optimal configuration of the spraying coverage and protective measures, making the expulsion effect more accurate and efficient.

[0083] Specifically, the spraying mechanism 2 further includes a regulating valve 26 for adjusting the flow of the spraying pipeline 22 .

[0084] like Fig.10 As shown, specifically, the regulating valve 26 includes a valve body 261, a valve plate 262, a rotating shaft 263 and a second motor 264. The valve body 261 is arranged on the spraying pipeline 22, the rotating shaft 263 extends into the valve body 261 and is connected to the valve plate 262, and the part of the rotating shaft 263 located outside the valve body 261 is connected to the second motor 264. The second motor 264 is used to drive the valve plate 262 to rotate through the rotating shaft 263.

[0085] When the plane of the valve plate 262 is perpendicular to the axis of the valve body 261, the valve body 261 is in a closed state. During use, the delivery device 21 delivers the pheromone repellent to the spraying pipeline 22 and passes through the regulating valve 26. The regulating valve 26 preferably adopts a small opening mode to adjust the flow of the spraying pipeline 22 so that a small amount of pheromone repellent passes through the spraying pipeline 22 and is sprayed out by the nozzle 23. If it is recognized that the squirrel has not left, the second motor 264 controls the rotation shaft 263 to rotate, so that the rotation shaft 263 drives the valve plate 262 to rotate, the opening of the regulating valve 26 gradually increases, the flow of the spraying pipeline 22 also increases, and the amount of pheromone repellent sprayed by the nozzle 23 also increases, thereby driving the squirrels more strongly.

[0086] Specifically, the bird feeder body 1 includes a bird feeding area 16 for storing bird food and a storage space 15 for storing the bird food, and the storage space 15 is communicated with the bird feeding area 16 .

[0087] Specifically, the bird feeder body 1 includes a shell 11, the storage space 15 is formed in the shell 11, the shell 11 is connected to a material box 12, and a portion of the material box 12 extends out of the shell 11 to form the bird feeding area 16. Bird food is stored in the storage space 15, and when the bird food in the bird feeding area 16 is eaten by a bird, the bird food in the storage space 15 will flow to the bird feeding area 16.

[0088] Specifically, a recessed portion 111 is provided on the housing 11 , and the recessed portion 111 is used for installing the identification device 3 .

[0089] Specifically, the feed box 12 is connected with a support member 13. The support member 13 is a mesh structure, which is convenient for birds to stand and eat.

[0090] Specifically, the outer shell 11 is equipped with a detachable cover 14 , and the user can conveniently fill the storage space 15 with bird food by opening the cover 14 , which not only facilitates the replenishment of the bird food and the maintenance of the storage space 15 , but also ensures that the bird food is effectively accumulated in the storage space 15 .

[0091] Embodiment 4 The difference between this embodiment and the second embodiment is that Fig.12 As shown, the shielding mechanism 4 includes a second baffle 43 and a first motor 441. The second baffle 43 is connected to the output end of the first motor 441. The second baffle 43 is driven to rotate by the first motor 441. A shielding portion 431 is provided on the second baffle 43. The second baffle 43 is driven to rotate by the first motor 441. When the shielding portion 431 of the second baffle 43 rotates to the bird feed area, the shielding portion 431 shields the bird feed to prevent the pheromone repellent from falling on the bird feed during the spraying process, thereby contaminating the bird feed.

[0092] Embodiment 5 The present invention also provides a method for using a bird feeder that drives away squirrels by spraying a pheromone repellent. The method is used for using the above-mentioned bird feeder that drives away squirrels by spraying a pheromone repellent. The method comprises the following steps: S1. Using the identification device 3 to continuously monitor the surrounding area of ​​the bird feeder body 1, capture and analyze animal activities, and determine whether the animal is a squirrel; S2. When the identification device 3 determines that the animal is a squirrel, the spraying mechanism 2 is activated, and the spraying mechanism 2 sprays pheromone repellent to drive away the squirrel.

[0093] Specifically, the step S2 further includes: S2-1. When the identification device 3 confirms that the detected animal is a squirrel, the shielding mechanism 4 drives the first baffle 41 to rise through the lifting mechanism 42, so that the first baffle 41 blocks the bird food to avoid contamination of the bird food by the sprayed pheromone repellent; S2-2. When the first baffle 41 rises into place, the nozzle 23 sprays pheromone repellent; S2-3. The rotating arm 262 drives the sleeve 261 to perform circular motion, causing the spraying pipeline 22 to swing.

[0094] Embodiment 6 The present embodiment is different from the fifth embodiment in that the step S2 includes: S2-4. When the identification device 3 confirms that the detected animal is a squirrel, the shielding mechanism 4 drives the second baffle 43 to rotate via the first motor 441, so that the shielding portion 411 of the first baffle 41 shields the bird food to prevent the sprayed pheromone repellent from contaminating the bird food.
