[0001] The invention relates to the technical field of bird feeders, in particular to a bird feeder with a squirrel repelling mechanism and a use method thereof. Background Art

[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. Therefore, developing a bird feeder that can effectively prevent squirrels from approaching and interfering with the bird feeding process is particularly important for maintaining the function of the bird feeder and improving its efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-8 The present invention provides a bird feeder with a squirrel repelling mechanism, comprising a bird feeder body 1, a squirrel repelling mechanism 2 for repelling squirrels, and an identification device 3 for identifying squirrels; wherein the squirrel repelling mechanism 2 and the identification device 3 are both connected to the bird feeder body 1. When the identification device 3 detects a squirrel, it activates the squirrel repelling mechanism 2, thereby executing the operation of repelling the squirrel. During the use of the bird feeder, the bird feeder body 1 needs to be installed in 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, it will control the squirrel driving mechanism 2 to operate and drive the squirrel away to prevent the squirrel from grabbing the bird food.

[0030] As an optional embodiment, the bird feeder body 1 includes an outer shell 11, an inner shell 12 and a feed box 13. The outer shell 11 is connected to the inner shell 12, and a recessed portion 121 is provided in the inner shell 12, which together with the outer shell 11 forms a storage space for storing bird food. The feed box 13 is connected to the outer shell 11 and the inner shell 12, and is partially located outside the outer shell 11 and the inner shell 12, and constitutes a bird feeding area, which is directly connected to the storage space. The identification device 3 is installed in the recessed portion 121 of the inner shell 12, and the squirrel repelling mechanism 2 is connected to the bottom of the feed box 13.

[0031] During use, the storage space is filled with bird food, and the bird food naturally flows into the feed box 13 through the structure connected to the storage space, forming a bird feeding area for birds to eat. The identification device 3 is responsible for monitoring the dynamics of the feed box 13 area, especially for identifying squirrels that may invade. Once the identification device 3 detects a squirrel and confirms its identity, it will activate the squirrel repelling mechanism 2, which will take necessary repelling actions to prevent squirrels from approaching the feeding area and snatching the bird food, ensuring the safe supply of bird food to birds.

[0032] As an optional embodiment, the feed box 13 is connected to a support member 14 in a mesh structure, wherein the support member 14 is designed as a mesh structure so that birds can stand on it conveniently. The outer shell 11 is equipped with a detachable cover 15, and by opening the cover 15, the user can conveniently fill the bird feed between the outer shell 11 and the inner shell 12. This ensures that the bird feed is effectively accumulated in the storage space, and is convenient for maintenance and replenishment of the bird feed.

[0033] This design not only optimizes the convenience of feeding, but also enhances the practical function of the bird feeder, making the feeding process more humane and safe. Through the support member 14 of the mesh structure, birds can stay and eat comfortably.

[0034] As an optional embodiment, a bird feeder with a squirrel repelling mechanism further includes a mounting base 4 connected to the bird feeder body 1, and the mounting base 4 is designed as an L-shaped structure. The mounting base 4 is mainly used to firmly connect the bird feeder to a tree trunk or a building. To this end, a plurality of mounting holes are preset on the mounting base 4, and these holes are used to fix the mounting base 4 to the tree trunk or the building by screws. In this way, the bird feeder body 1 can be stably combined with the mounting base 4, ensuring the stability and safety of the bird feeder when used outdoors.

[0035] As an optional embodiment, the squirrel driving mechanism 2 includes a first motor 22 and a driving lever 21. The first motor 22 is connected to the driving lever 21 and is responsible for driving the driving lever 21 to swing effectively to achieve the purpose of driving away the squirrel. The driving lever 21 is designed to include a connecting portion 211, a first bending portion 212, a second bending portion 213, a first toggle portion 214 and a second toggle portion 215, wherein the connecting portion 211 is directly connected to the output end of the first motor 22.

[0036] During operation, when the first motor 22 is started, it drives the connecting part 211 to rotate, and this action is effectively transmitted to the first toggle part 214 through the design of the first bending part 212 and the second bending part 213. The first toggle part 214 then drives the second toggle part 215 to perform reciprocating swings. This coherent power transmission mechanism not only enhances the response speed of the device, but also ensures that the swinging force is sufficient to drive away squirrels while avoiding harm to birds. Through such a design, the squirrel-repelling mechanism 2 can respond quickly and effectively to the invasion of squirrels, protect bird food from being snatched, and maintain the safety and friendly environment of the bird feeder.

[0037] As an optional embodiment, a driving cavity 5 is installed at the bottom of the bird feeder body 1, wherein the output end of the first motor 22 is connected to the connecting portion 211 through a torque converter 23. The torque converter 23 is installed inside the driving cavity 5, and its main function is to adjust the rotation torque of the driving lever 21 to meet the driving requirements in different situations.

[0038] In operation, when the first motor 22 starts to drive, the torque converter 23 precisely controls the rotational torque so that the driving lever 21 can effectively drive and drive away the squirrel approaching the bird feeder. If the squirrel fails to be driven away in the first operation or the squirrel continues to approach, the torque converter 23 will automatically increase the rotational torque of the lever 21 to ensure that the squirrel is effectively driven away. This intelligent adjustment mechanism not only improves the driving efficiency, but also ensures that the action is strong enough, while avoiding damage to the birds and the bird feeder itself, and maintaining the harmony and safety of the feeding environment.

[0039] The torque converter 23 includes an input shaft 231, a transmission shaft 232, an output shaft 233, a first driving gear 234, a second driving gear 235, a driven gear 236, a first transmission gear 237, a second transmission gear 238, a third transmission gear 239, a sliding sleeve 2310, a connecting handle 2311 and an electric push rod 2312. The input shaft 231 is directly connected to the output end of the first motor 22, and the first driving gear 234 and the second driving gear 235 are both mounted on the input shaft 231. The output shaft 233 is connected to the connecting portion 211 through the driven gear 236, and the driven gear 236 is meshed with the first transmission gear 237, which is connected to the transmission shaft 232.

[0040] On the transmission shaft 232, strip protrusions 2313 in an annular equidistant array are provided, and corresponding strip grooves are designed inside the sliding sleeve 2310, so that the sliding sleeve 2310 can be sleeved and slidably connected with the transmission shaft 232 through the strip protrusions 2313. The second transmission gear 238 and the third transmission gear 239 are both connected to the sliding sleeve 2310. The pitch circle diameter of the first driving gear 234 is larger than that of the second driving gear 235, so that the pitch circle diameter of the second driving gear 238 is meshed with the first driving gear 234, and the pitch circle diameter of the third driving gear 239 is the same as that of the second driving gear 235. The connecting handle 2311 is rotatably connected to the sliding sleeve 2310, and the electric push rod 2312 is connected to the connecting handle 2311.

[0041] The working process of the system is described in further detail as follows: the first motor 22 is started to drive the input shaft 231 to rotate. Figure 5 As shown, the first driving gear 234 is meshed with the third transmission gear 239. The input shaft 231 drives the first driving gear 234 to rotate, thereby driving the third transmission gear 239 to rotate. Subsequently, the third transmission gear 239 drives the sliding sleeve 2310 to rotate, and the sliding sleeve 2310 further drives the transmission shaft 232 to rotate through the bar-shaped protrusion 2313 inside it. The transmission shaft 232 drives the first transmission gear 237 to rotate, and the gear is meshed with the driven gear 236, thereby pushing the output shaft 233 and the connected driving lever 21 to perform a rotation action. The rotation direction of the driving lever 21 can be changed by changing the rotation direction of the output end of the first motor 22, and the swing of the driving lever 21 can be achieved by reciprocatingly changing the rotation direction of the output end of the first motor 22.

[0042] In this configuration, the swing of the driving lever 21 has a certain torque, which is sufficient to perform a basic driving operation. However, if the recognition device 3 detects that the driving lever 21 fails to effectively drive away the squirrel, the electric push rod 2312 will be activated. The electric push rod 2312 pushes the connecting handle 2311 to move, so that the connecting handle 2311 drives the sliding sleeve 2310 to slide along the transmission shaft 232. This movement causes the third transmission gear 239 in the sliding sleeve 2310 to disengage from the first driving gear 234, and at the same time, the second transmission gear 238 is meshed with the second driving gear 235. The rotation of the second driving gear 235 drives the second transmission gear 238 to rotate, the second transmission gear 238 drives the transmission shaft 232 to rotate, the transmission shaft 232 drives the output shaft 233 to rotate, and the output shaft 233 drives the driving lever 21 to rotate. Since the pitch circle diameter of the first driving gear 234 is larger than that of the second driving gear 235, this configuration amplifies the torque of the driving lever 21 through the second transmission gear 238. This enhanced torque enables the driving lever 21 to swing with greater force, thereby effectively driving the squirrel away completely, ensuring the normal operation of the bird feeder and the safety of the bird food.

[0043] This embodiment adopts a progressive driving strategy, which preferentially uses a smaller driving force to try to drive away the squirrel, which has the advantage of avoiding unnecessary harm to the squirrel to the greatest extent. In the initial state, the torque when the driving lever 21 is operated is small, which is enough to deal with small or slightly intrusive squirrels.

[0044] If the identification device 3 detects that the squirrel has not been driven away after the initial operation, the system will automatically adjust to increase the torque of the driving lever 21. During this process, the electric push rod 2312 will be activated to push the connecting handle 2311, causing the sliding sleeve 2310 to move along the transmission shaft 232. This movement causes the third transmission gear 239 in the sliding sleeve 2310 to disengage from the first driving gear 234, and causes the second transmission gear 238 to mesh with the second driving gear 235, thereby increasing the torque of the driving lever 21. The enhanced torque ensures that even large squirrels can be effectively driven away, achieving effective driving of squirrels and ensuring the safety of bird food and birds.

[0045] This embodiment adopts a progressive expulsion strategy to achieve efficient and humane expulsion of squirrels, which has significant beneficial effects. First, by using a small torque to try to expel the squirrels for the first time, this method can not only effectively avoid causing harm to the squirrels, but also ensure the harmony and safety of the environment around the bird feeder. This has important ecological significance for protecting wild animals and their habitats.

[0046] Secondly, for those large or stubborn squirrels, if the initial expulsion fails, the system can automatically adjust and increase the torque of the expulsion lever 21. This increase in torque can ensure that squirrels are effectively expelled without causing additional damage, thereby protecting the bird food in the bird feeding area from being snatched. This intelligently adjusted expulsion mechanism not only improves the efficiency of the bird feeder, but also enhances the adaptability of the device to different situations.

[0047] Overall, this design takes into account the dual needs of animal protection and resource protection. Through intelligent control and humane expulsion methods, it achieves the goal of protecting birds' food sources while minimizing interference with other animals, demonstrating the combination of environmental protection and technological innovation.

[0048] As an optional embodiment, the first toggle part 214 is equipped with a second motor 216, and the second toggle part 215 is connected to the first toggle part 214 through a rotational connection. The output end of the second motor 216 is directly connected to the second toggle part 215, responsible for driving the second toggle part 215 to rotate. This configuration allows the second motor 216 to not only drive the first toggle part 214 to rotate, but also accurately adjust its angle during the process of driving away squirrels.

[0049] Through this angle adjustment mechanism, the first toggle portion 214 can more flexibly adapt to squirrels of different sizes and action patterns, thereby improving the expulsion effect. Such a design enhances the adaptability and efficiency of the expulsion mechanism, ensuring that while minimizing the harm to squirrels, squirrels can be effectively prevented from intruding into the bird feeding area. In addition, this adjustable angle function also enables the bird feeder to be more widely adapted to various installation locations and environments, further improving its practicality and flexibility.

[0050] As an optional implementation, the identification device 3 includes: Infrared sensor 31: This sensor is used to continuously monitor moving heat sources in the food tray area, such as small animals such as squirrels. It can detect infrared radiation generated by body temperature, thereby effectively detecting animals immediately when they enter the monitoring area. The infrared sensor 31 is a PIR infrared motion monitoring sensor.

[0051] Camera 32: Linked with infrared sensor 31. When infrared sensor 31 detects a moving heat source, camera 32 automatically activates and captures real-time images of the area. This allows the system to visually identify animals entering the bird feeding area.

[0052] Image transmission module 33: responsible for transmitting the images captured by camera 32 to the server backend in real time. This module ensures that the image data is transmitted quickly and securely for further analysis.

[0053] Server backend: The server is equipped with an AI algorithm model optimized for the smart bird feeder scenario, which can analyze the image received from the image transmission module 33 and accurately identify whether there are squirrels in the image. The design of this AI model focuses on improving the accuracy of recognition and reducing the false alarm rate to ensure that the repelling mechanism is activated only when a squirrel is actually detected.

[0054] Control module 34: Based on the recognition result of the server background, when it is confirmed that there is a squirrel in the image, the control module 34 will automatically start the squirrel repelling mechanism of the bird feeder. This includes activating the repelling lever 21 and its related mechanisms, such as the first motor 22 and the second motor 216, and the torque conversion mechanism 23, so as to adjust the torque and angle of the repelling lever 21 to effectively repel the squirrel.

[0055] Furthermore, the server backend is mainly responsible for receiving, processing and analyzing data transmitted from identification devices (such as cameras and infrared sensors).

[0056] The server backend receives real-time image data from the bird feeder camera 32 through the image transmission module 33, and may also receive motion data provided by other sensors, such as the infrared sensor 31. The server backend is equipped with an artificial intelligence (AI) model optimized for identifying squirrels and other potentially invading animals. This AI model uses deep learning technology and is trained on a large number of animal image data sets to distinguish between squirrels, birds and other animals. The model is designed to improve the accuracy of recognition and reduce the possibility of false positives and false negatives. After receiving the image data, the AI ​​model analyzes the image content to determine whether there is a squirrel. The analysis process includes detecting features such as the shape, size, and movement pattern of the animal in the image to ensure accurate recognition. Once the AI ​​model confirms that there is 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 squirrel repelling mechanism 2. After receiving the signal, the repelling mechanism performs the corresponding repelling action according to the set program (such as using a smaller repelling force first, and then gradually increasing it if it fails). The server backend also includes the function of maintaining and updating the AI ​​model. By continuously collecting feedback data during use, the backend can iteratively optimize the AI ​​model to improve its adaptability and accuracy.

[0057] The present invention also provides a method for using a bird feeder with a squirrel repelling mechanism, the method comprising the following steps: Step 1: Start the identification device 3 to continuously monitor the area around the bird feeder body 1 to detect whether a squirrel enters the bird feeding area.

[0058] Step 2: Once the identification device 3 detects a squirrel, the squirrel driving mechanism 2 is immediately activated. The squirrel driving mechanism 2 performs a driving operation on the squirrel by swinging the driving lever 21, ensuring that the squirrel is effectively kept away from the bird feeding area.

[0059] Specifically, step 2 includes: Step 2A: Once the identification device 3 senses the activity of the squirrel, the control module 34 immediately activates the squirrel driving mechanism 2 and starts the basic driving operation. This operation is implemented by the first motor 22, which accurately controls the initial low-torque swing of the driving lever 21 through the torque converter 23, and tries to drive the squirrel away in a gentle manner, thereby effectively reducing potential harm to the animal, while reducing the sound and vibration of the device operation, and enhancing the user experience and animal welfare.

[0060] Step 2B: If step 2A fails to successfully drive away the squirrel, the identification device 3 continues to monitor and sends a signal to the control module 34 that the squirrel continues to exist. In response, the control module 34 adjusts the drive away strategy and activates the electric push rod 2312, which acts on the connecting handle 2311 to move the sliding sleeve 2310 along the transmission shaft 232. This displacement changes the transmission configuration, causing the third transmission gear 239 to disengage from the first driving gear 234 and the second transmission gear 238 to engage with the second driving gear 235. This adjustment increases the torque of the drive away lever 21 through the second transmission gear 238, thereby applying a stronger drive away force to larger or more stubborn squirrels, ensuring that the squirrels are effectively expelled while protecting the bird's food from interference. This staged force adjustment not only improves the drive away effect, but also optimizes energy use, making the equipment operation more economical and environmentally friendly.

[0061] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
