Description

Technical Field

[0001] This utility model relates to the field of birdwatching technology, specifically to a birdwatching device. Background Technology

[0002] Birdwatching devices, used by bird enthusiasts to observe bird activity, are widely used in ecological research, science education, and leisure activities. Existing birdwatching devices typically consist of a stand, feeding device, and observation tools; some products are equipped with camera units for remote observation. However, different designs of birdwatching devices vary in terms of structural protection, level of intelligence, and functional integration.

[0003] In existing technologies, while some birdwatching devices are equipped with camera units for photographing birds, these units are typically directly exposed to the outdoor environment and located near feeding areas. This makes them susceptible to pecking, scratching, or contamination from bird droppings, leading to lens damage or decreased image quality. Furthermore, outdoor elements like wind and rain can cause corrosion or water ingress, shortening their lifespan. Especially in the absence of effective physical insulation, larger birds may even directly touch the camera unit, causing mechanical damage.

[0004] Therefore, how to improve the protection capabilities of camera units and prevent interference from non-target animals remains a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a birdwatching device that addresses the shortcomings of the existing technology. This device effectively protects the camera unit from direct contact with birds and the influence of environmental pollutants, extends the service life of the equipment, and reduces the risk of mechanical damage through physical isolation.

[0006] The technical solution is as follows:

[0007] A birdwatching device includes: a birdwatching device body, detachably disposed on a first side of a light-transmitting barrier, the birdwatching device body having an observation area; and a camera unit disposed on a second side of the light-transmitting barrier and used to photograph the observation area, wherein the light-transmitting barrier is located between the birdwatching device body and the camera unit.

[0008] As can be seen from the above, the present invention effectively protects the camera unit through a physical isolation structure, which has the advantages of effectively protecting the camera unit from direct contact with birds and the influence of environmental pollutants, extending the service life of the equipment, and reducing the risk of mechanical damage through physical isolation.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] In existing technologies, the camera units of birdwatching devices are often directly exposed near the feeding area, making them susceptible to damage from bird pecking or environmental factors. While some devices incorporate physical barriers, these often suffer from fixed, non-adjustable structures and limited protective effectiveness. For example, in a backyard setting, when birds approach the feeding dish, the camera unit may experience short circuits due to wing movements that could cause rainwater seepage, affecting long-term stable operation.

[0032] To address these issues, analysis revealed that the primary cause of damage to the camera unit was its excessive proximity to the birds' activity area. Attempts were made to physically isolate the camera unit from the feeding area, but traditional isolation methods obstructed the field of view. Further research showed that translucent materials could form a physical barrier without affecting light transmission. Therefore, it was proposed to place the camera unit and the birdwatcher itself on opposite sides of a translucent barrier, achieving a balance between physical protection and optical transmission through the barrier.

[0033] Therefore, refer to Figures 1-8This application proposes a device including a birdwatching device body and a camera unit 3. The birdwatching device body is detachably mounted on the first side of a light-transmitting barrier 1 and includes an observation area 2. The camera unit 3 is mounted on the second side of the light-transmitting barrier 1 for photographing the observation area 2. The light-transmitting barrier 1 is located between the two.

[0034] The birdwatching device itself refers to the container structure that houses the area where birds can move around. It can be constructed using a plastic or metal frame with transparent panels, and its position can be adjusted via detachable connections. The light-transmitting barrier 1 is a physical barrier that allows light to pass through, preventing birds from contacting the camera unit 3 while ensuring image quality. The observation area 2 is a specific space for birds to perch, which can be formed by setting up feeding trays 9 or perches, providing a stable target area for the camera unit 3.

[0035] It should be noted that the light-transmitting barrier 1 refers to a structural component that allows light to pass through while physically separating two spaces or areas. Its material can be a transparent or translucent glass plate, plexiglass plate, polycarbonate plate, transparent resin plate, or a sandwich material with optical transmittance. The light-transmitting barrier 1 can be a single-layer or multi-layer structure, and its surface can be coated with anti-fog, anti-reflective, or UV-protective functional coatings to adapt to different environments and usage requirements.

[0036] It should be noted that the first side of the light-transmitting isolator 1 refers to the side of the light-transmitting isolator 1 along its thickness direction, which can correspond to the side facing the observation area 2 or the equipment for collecting optical signals, such as the side facing the camera unit 3, the optical sensor, or the observation subject. The second side of the light-transmitting isolator 1 refers to the side of the light-transmitting isolator 1 opposite to the first side along its thickness direction, which can correspond to the side facing the external environment, the observed object, or the light source.

[0037] In practice, the birdwatching device is fixed to the outside of the window glass via clips or magnetic attachment, forming an observation space that includes a feeding area. The camera unit 3 is installed indoors, with its lens facing the observation area 2. When birds enter the observation area 2 to feed, the light-transmitting barrier 1 prevents their wings or beaks from contacting the camera unit 3, while the glass material ensures light penetration, allowing the camera unit 3 to clearly record the bird's behavior. The detachable structure allows for the replacement of different sized birdwatching devices to suit various bird sizes, adapting to diverse application scenarios.

[0038] Compared to existing technologies, traditional devices place the camera unit 3 and the feeding area in the same space, which cannot avoid the risk of mechanical contact. This solution uses a light-transmitting insulating layer 1 to create a physical protective layer while maintaining the shooting function, thus resolving the contradiction between equipment damage and image quality degradation.

[0039] Through the above technical solution, this application effectively prevents birds from directly impacting the camera unit 3, reduces equipment maintenance frequency, and extends the outdoor usage period. The light-transmitting barrier 1 maintains optical transmittance while blocking rain and foreign objects, ensuring image clarity. The detachable structure enhances the device's adaptability to different observation scenarios, providing a hardware foundation for long-term stable observation.

[0040] This application further proposes that the main body of the birdwatching device includes a back plate 4, on which an observation hole 4a is provided, and the camera unit 3 takes pictures of the observation area 2 through the observation hole 4a.

[0041] The back plate 4 refers to the plate-shaped component that forms the supporting structure of the birdwatcher body. It can be made of metal or high-strength plastic and is used to fix the observation hole 4a and provide a mounting base for other components. The observation hole 4a refers to the through-hole structure opened on the back plate 4. It can be made of circular or rectangular holes and its position is aligned with the optical axis of the camera unit 3 to ensure that the field of view of the camera unit 3 covers the observation area 2.

[0042] In practice, the backplate 4, as the main load-bearing component of the birdwatching device, is formed into an observation hole 4a through machining or injection molding. The camera unit 3 is positioned on the other side of the light-transmitting barrier 1, with its lens facing the observation hole 4a, allowing light to pass through the observation hole 4a and enter the camera unit 3 to form an image. The aperture size of the observation hole 4a can be adjusted according to the field of view of the camera unit 3 to ensure that the captured image completely covers the bird activity area within the observation area 2.

[0043] This embodiment achieves physical isolation between the camera unit 3 and the observation area 2, effectively preventing equipment damage caused by bird collisions or excrement pollution, reducing the maintenance frequency of the camera unit 3, and ensuring that the clarity of the captured images is not affected by the structure.

[0044] Reference Figure 8 This application further proposes that the back plate 4 is also provided with a connector 5, and the back plate 4 is detachably connected to the light-transmitting barrier 1 through the connector 5.

[0045] The connector 5 refers to the mechanical structure used to achieve a detachable connection between the back panel 4 and the light-transmitting barrier 1. Its function is to provide a stable fixing method while allowing for quick disassembly. A detachable connection refers to a connection method that does not compromise the structural integrity, such as through a sliding groove or plug-in structure. Its function is to facilitate the user in cleaning, replacing, or adjusting the installation position of the back panel 4.

[0046] Furthermore, the connector 5 includes a suction cup 5a, on which a snap-fit ​​part 5a1 is provided, and on the back plate 4 a snap-fit ​​hole 4b that mates with the snap-fit ​​part 5a1; the snap-fit ​​hole 4b has a keyhole-type structure that is narrow at the top and wide at the bottom, including a narrow guide section for insertion and a receiving section with a diameter larger than the guide section.

[0047] The snap-fit ​​component 5a1 can be integrally disposed on the back of the suction cup 5a. The snap-fit ​​hole 4b has a rod portion 4b1 and a ball head 4b2. The size of the rod portion 4b1 matches the guide section, and the outer diameter of the ball head 4b2 is larger than the width of the guide section and matches the receiving section.

[0048] Specifically, during installation, the rod 4b1 of the snap-fit ​​part 5a1 is first inserted into the guide section of the snap-fit ​​hole 4b on the back plate 4, and then moved down to allow the ball head 4b2 to enter the receiving section and form an interference or limiting fit with the hole wall, thereby realizing a detachable and stable connection between the suction cup 5a and the back plate 4; during disassembly, the ball head 4b2 is pulled out after being pushed back into the guide section along the opposite path.

[0049] Compared to existing technologies, simply attaching adhesive or screws to glass is inconvenient to maintain and has poor reusability. This solution uses a combination of suction cup 5a and keyhole snap-fit ​​to achieve quick installation, stable positioning, and convenient replacement.

[0050] Reference Figures 5-6 This application further proposes that the main body of the birdwatching device also includes a base plate 6 and a brim 7, and the back plate 4, the base plate 6 and the brim 7 are arranged to form the main body of the birdwatching device.

[0051] The base plate 6 refers to the planar support structure located at the bottom of the back plate 4 and perpendicularly connected to it. It can be made of a reinforced plastic sheet using injection molding, serving to support the internal components of the observation area 2 and distribute the load. The brim 7 refers to the arc-shaped shielding component extending outward from the top of the back plate 4. It can be made of polycarbonate material using a hot bending process, serving to prevent rainwater from directly flowing into the observation hole 4a and creating a visually shielded area. The enclosure formation refers to the semi-enclosed space formed by the edge connection of the back plate 4, base plate 6, and brim 7. This can be achieved using mortise and tenon joints combined with waterproof sealing strips, creating an observation environment with dust and splash protection.

[0052] Specifically, after the back panel 4 is fixed to the surface of the light-transmitting isolator 1 by the connector 5, the bottom plate 6 is connected to the bottom of the back panel 4 at a vertical angle to form an L-shaped base, and the brim 7 is connected to the top of the back panel 4 at an inclined angle to form a top covering structure. The edges of the back panel 4, the bottom plate 6, and the brim 7 are continuously spliced ​​to form a semi-enclosed space with a front opening, and the interior of this space is defined as the observation area 2. The observation hole 4a is set in the middle area of ​​the back panel 4, and its axis is parallel to the surface of the light-transmitting isolator 1, so that the camera unit 3 can take unobstructed pictures of the observation area 2 through the light-transmitting isolator 1 and the observation hole 4a.

[0053] Compared to existing technologies, most birdwatching devices use a single-layer plate structure or an open frame structure, which cannot effectively prevent rainwater penetration and animal contact. This solution forms a physical barrier through a three-sided enclosure structure, which maintains the light transmittance of the observation hole 4a while preventing bird droppings from flowing into the observation area 2 along the surface of the back plate 4, and prevents animals such as squirrels from entering the device from the top or sides.

[0054] This application further proposes that the base plate 6 has side plates 8 on both sides, and the side plates 8 are integrally formed with the base plate 6. The side plates 8 extend from both sides of the base plate 6 as a supporting structure, and there are no seams or splicing marks at the connection between the side plates 8 and the base plate 6. During bird activity or external impact, the integral structure formed by the side plates 8 and the base plate 6 can resist the lateral force generated by the sliding of the feeding dish 9, avoiding deformation or breakage caused by the separate connection. When the feeding dish 9 slides along the side plates 8, the side plates 8 physically constrain the movement trajectory of the feeding dish 9, preventing it from deviating from the predetermined position.

[0055] The side plates 8 refer to the plate-like structures located on both sides of the base plate 6. They can be made of plastic or metal and formed integrally with the base plate 6 through injection molding or die casting processes. This enhances the structural strength of the birdwatcher and limits the lateral displacement of the feeding tray 9. One-piece molding refers to the process of creating an inseparable continuous entity between the side plates 8 and the base plate 6 through mold processing. This can be achieved using injection molding or die casting processes, eliminating the connection gaps between the separate structures and improving overall rigidity.

[0056] Reference Figure 3 This application further proposes that the main body of the birdwatching device includes a feeding tray 9, with guide grooves 9a on both sides of the feeding tray 9, and guide strips 9b on the side plate 8 that cooperate with the guide grooves 9a. The feeding tray 9 is slidably connected to the side plate 8 through the guide grooves 9a.

[0057] The feeding tray 9 refers to a container used to hold bird feed. The guide groove 9a is a recessed structure on the side of the feeding tray 9, used to form a sliding fit with the guide strip 9b on the side plate 8. The guide strip 9b is a protruding structure on the side plate 8, whose cross-sectional shape matches the guide groove 9a to achieve sliding constraint. The sliding connection refers to an assembly method in which the feeding tray 9 and the side plate 8 achieve linear movement through the cooperation of the guide groove 9a and the guide strip 9b. Specifically, a clearance fit or a transition fit can be used to achieve this, allowing the feeding tray 9 to move smoothly on a fixed track.

[0058] Specifically, the feeding tray 9 slides into the side plate 8 via guide grooves 9a on both sides, allowing it to be pushed in or pulled out along the length of the side plate 8 during operation. When feed needs to be changed or cleaned, the feeding tray 9 can be completely removed from the side plate 8, and then pushed back into place after maintenance. The clearance between the guide grooves 9a and the guide strips 9b is controlled within a range that allows for sliding but prevents loosening, ensuring the feeding tray 9 remains stable when carrying feed. The side plate 8 and the guide strips 9b are manufactured using a one-piece molding process to avoid assembly errors affecting sliding accuracy.

[0059] Compared to existing technologies, traditional birdwatching devices often use bolts or clips for fixing the feeding tray 9, requiring individual removal of fasteners during disassembly, resulting in low efficiency and easy wear and tear on components. This solution utilizes the sliding engagement of the guide groove 9a and guide strip 9b to achieve tool-free assembly and disassembly of the feeding tray 9, significantly reducing maintenance time. Existing technologies lack a guiding structure between the feeding tray 9 and the side plate 8, requiring repeated adjustments during installation. This solution, however, achieves precise positioning through a pre-set sliding track, preventing feed spillage due to misalignment.

[0060] This application further proposes that the feeding tray 9 includes at least two adjacent feeding troughs, and the bottom of the feeding troughs is provided with multiple drain holes 9c.

[0061] The feeding trough refers to a recessed structure used to hold feed. It can be made using a split or one-piece molding process. Adjacent feeding troughs can allow for the separate storage of different types of feed, avoiding feed mixing and contamination. The drain hole 9c refers to a through hole located at the bottom of the feeding trough. It can be made using a circular, square, or strip-shaped hole structure to drain feed residue, bird droppings, or rainwater, maintaining the hygiene of the feeding area.

[0062] In practice, when birds are active in the feeding dish 9, different types of feed, such as grains and fruits, can be placed in the two adjacent feeding troughs respectively, achieving precise feeding. Debris or excrement produced by the birds during feeding can fall naturally through the drain hole 9c at the bottom, preventing accumulation in the feeding troughs. For example, in rainy weather, rainwater can be quickly drained along the surface of the feeding trough through the drain hole 9c, preventing water accumulation and feed spoilage. A guide channel or collection container can be installed at the bottom of the feeding dish 9 to centrally process the discharged waste.

[0063] Compared to existing technologies, traditional birdwatching devices typically use a single feed container, and mixing different types of feed makes it difficult for birds to pick and choose their food, and the feed is prone to spoilage. Existing devices lack a drainage structure, and feed residue and excrement accumulate, requiring frequent manual cleaning. This solution uses a trough design to achieve classified storage of feed, combined with a bottom drainage hole 9c to form a self-cleaning structure, effectively reducing maintenance frequency.

[0064] This application further proposes that a support member 10 is provided on the side of the feeding tray 9 away from the light-transmitting barrier 1, and the feeding tray 9 and the support member 10 are integrally formed.

[0065] Among them, the support component 10 refers to the rigid structural component set on the side of the feeding dish 9 away from the light-transmitting barrier 1. Specifically, it can be made of injection-molded plastic or metal material, which is used to provide stable support for the feeding dish 9 and prevent the feeding dish 9 from tilting or shifting due to the activities of birds or non-target animals.

[0066] Specifically, the support member 10 is located on the side of the feeding dish 9 away from the light-transmitting barrier 1. When birds or non-target animals move on the feeding dish 9, the support member 10 resists external forces through its rigid structure, maintaining the balance of the feeding dish 9. The feeding dish 9 and the support member 10 are formed into an integral structure through a one-piece molding process, eliminating the weak links at the connection points in traditional split designs, making the feeding dish 9 less prone to deformation or damage when subjected to external forces. For example, when squirrels climb or birds peck at the feeding dish 9, the support member 10 can distribute the force and maintain the stability of the feeding dish 9, avoiding structural failure caused by local stress concentration.

[0067] This embodiment effectively solves the problem that the feeding tray 9 is prone to displacement or damage under the disturbance of animal activities. The integrated support component 10 improves structural stability, reduces maintenance frequency, and at the same time reduces feed waste and obstruction of the shooting area of ​​the camera unit 3 caused by the tilting of the feeding tray 9, ensuring the long-term reliable operation of the bird watching device.

[0068] Furthermore, the support member 10 includes a first support vertical bar 10a, a second support vertical bar 10b, a third support vertical bar 10c, a first support horizontal bar 10d, and a second support horizontal bar 10e. The first support vertical bar 10a and the second support vertical bar 10b are spaced apart, and the third support vertical bar 10c is located between the first support vertical bar 10a and the second support vertical bar 10b. The first support horizontal bar 10d and the second support horizontal bar 10e are respectively connected to the first support vertical bar 10a, the second support vertical bar 10b, and the third support vertical bar 10c. The first support vertical bar 10a, the second support vertical bar 10b, the third support vertical bar 10c, the first support horizontal bar 10d, and the second support horizontal bar 10e are integrally formed.

[0069] The vertical support bars are strip-shaped structures extending in the vertical direction, and can be made of metal or engineering plastic materials. They are used to bear the vertical load of the feeding dish 9 and distribute the pressure. The horizontal support bars are strip-shaped structures extending in the horizontal direction, and can be made of the same material as the vertical support bars. They are used to connect multiple vertical support bars to form a stable frame structure. One-piece molding refers to integrating multiple support components 10 into a single solid structure through injection molding or casting processes. This can be achieved using mold forming technology to eliminate connection gaps and enhance overall rigidity. The support components 10 form a basic support surface through the spaced arrangement of the first and second vertical support bars 10a and 10b, respectively. The third vertical support bar 10c is centrally located to provide additional support points. The first and second horizontal support bars 10d and 10e respectively connect the upper and middle parts of the three vertical support bars laterally, forming a double-layer cross-reinforced structure. The one-piece molded support components 10 avoid the loosening risks that may occur with bolts or welding in traditional assembly structures, while ensuring that the force on the feeding dish 9 is evenly distributed when carrying birds.

[0070] In some specific embodiments, the spacing between the supporting vertical bars can be 1 / 3 to 1 / 2 of the width of the feeding tray 9, and the height of the horizontal bars can be adjusted according to the installation requirements of the feeding tray 9. The cross-sectional shape of the supporting vertical bars can be designed as rectangular or trapezoidal to improve bending resistance, and an arc-shaped transition structure can be provided at the connection between the horizontal and vertical bars to reduce stress concentration.

[0071] Compared to existing technologies, traditional birdwatching devices often use single beams or simple supports, lacking multi-point support and rigid connections, making them susceptible to structural deformation due to bird activity or external impacts. This solution significantly improves the torsional resistance of the support structure through a cross-layout of three vertical bars and two horizontal bars, while the one-piece molding process eliminates the risk of crevice corrosion associated with traditional assembled components.

[0072] Through the above technical solution, this application can effectively prevent the feeding tray 9 from tilting or sinking when birds trample on it or when food accumulates, avoiding the problem of the feeding tray 9 getting stuck or falling off due to support failure, thereby ensuring that the camera unit 3 can continuously and stably film bird activities in the observation area 2. The rigid structure of the support member 10 can also accommodate birds of different weights, reducing maintenance needs caused by device deformation.

[0073] This application further proposes that the birdwatching device is also equipped with a repelling device 11, which is used to spray a repelling scent when a squirrel is detected.

[0074] The repelling device 11 refers to a device that repels animals by releasing a specific odor. Specifically, it can be implemented using a combination of a miniature air pump and a liquid reservoir, filled with a repellent liquid such as peppermint oil or capsaicin solution. Squirrel detection refers to sensing the presence of the target animal through sensors, specifically infrared sensors or image recognition modules. When the squirrel's body shape or movement trajectory is detected, a repelling action is triggered. Spraying the repellent odor refers to dispersing the repellent substance in the form of atomization or mist. Specifically, a solenoid valve can control the nozzle to spray directionally, covering the feeding dish 9 and its surrounding area.

[0075] Specifically, the repelling device 11 is configured to operate in conjunction with the detection device 12. When the infrared sensor detects the squirrel's body temperature signal around the feeding dish 9 or the image recognition module captures the squirrel's features through the camera, the main control unit immediately activates the air pump and solenoid valve, causing the repelling liquid in the storage tank to diffuse outwards as atomized particles through the nozzle. The spray direction can be set to face outwards from the feeding dish 9 to avoid affecting the birds' activities in the observation area 2.

[0076] It should be noted that when the detection device 12 and the identification module jointly determine that the visiting object is a squirrel, the main control unit issues a driving command, and the driving device 11 starts a spraying cycle: the metering pump outputs 10ml of peppermint oil, and the screw feeder simultaneously feeds in 50g of sulfur powder. After the two are fully mixed in the mixing chamber, they are atomized and sprayed out through the nozzle. The spraying direction is directed towards the outer edge of the feeding tray 9 and its adjacent area to reduce the impact on birds in the observation area 2.

[0077] Furthermore, the repelling device 11 can integrate an infrasound generator to emit low-frequency sound waves while spraying odors, creating a composite repelling effect.

[0078] In one specific implementation, the sound-based deterrent unit 11a is configured to emit ultrasonic signals with a frequency range of 18kHz-22kHz. Utilizing the squirrel's sensitivity to high-frequency sound waves, which are imperceptible to the human ear, it achieves a non-interference deterrent effect. The signal is generated by the main control unit or retrieves waveform data stored in the drive circuit. After being amplified by a power amplifier, it drives the piezoelectric ceramic speaker to emit the signal. The continuous operating time is preferably 3-5 seconds, and it can be cyclically triggered as long as the squirrel's continued presence is detected.

[0079] In another specific implementation, the sound repelling unit 11a is configured to emit low-frequency infrasound waves, preferably in the frequency range of 15Hz-25Hz. By generating slight low-frequency vibrations in the air and support structure, the squirrel senses the abnormal environment and actively leaves. This mode can be triggered synchronously with the odor repelling unit, that is, while spraying 10ml of peppermint oil + 50g of sulfur powder, a low-frequency signal is emitted for 2-4 seconds, forming a multi-sensory repelling effect.

[0080] Compared to existing technologies, current birdwatching devices lack an active deterrent mechanism for non-target animals, and relying solely on physical barriers or human intervention is insufficient to prevent squirrel intrusion in real time. This solution, through a sensor-based detection and scent-based deterrent mechanism, can immediately trigger a deterrent action when squirrels approach the feeding area, effectively preventing feed from being stolen or the device from being damaged, while also avoiding interference with bird activities.

[0081] This application further proposes that the birdwatching device is also equipped with a detection device 12, which is used to detect whether there is an object on the support 10 and / or the feeding tray 9.

[0082] Among them, the detection device 12 refers to the sensing component used to collect the bearing state or occupancy state, which can be realized by pressure, displacement or photoelectric principles to adapt to different structural arrangements.

[0083] Specifically, the detection device 12 collects the load changes or displacement changes generated on the support surface and outputs a detection signal indicating the presence or absence of an object, providing a trigger basis for subsequent shooting or driving decisions.

[0084] Reference Figure 4 This application further proposes that the detection device 12 is located between the bottom of the feeding tray 9 and the base plate 6.

[0085] The detection device 12 is located between the bottom of the feeding tray 9 and the base plate 6. This means that the detection device 12 is clamped in the mounting cavity between the bearing surface of the feeding tray 9 and the supporting surface of the base plate 6. This allows it to sense changes in bearing capacity while avoiding direct contact with the outside. An installation space is reserved between the lower surface of the feeding tray 9 and the upper surface of the base plate 6. The detection device 12 is fixed by a limiting rib or mounting base. The force path is transmitted from the feeding tray 9 to the detection device 12 and then to the base plate 6, achieving high-sensitivity detection.

[0086] In one embodiment, the detection device 12 is a Hall sensor.

[0087] Specifically, a magnetic element is fixed to the bottom of the feeding dish 9, and a Hall sensor is installed in a mounting bracket at the corresponding position on the base plate 6. When a bird or other animal lands on the feeding dish 9, the dish 9 undergoes a slight displacement or deformation due to the force applied, thereby changing the relative position between the magnetic element and the Hall sensor, causing a change in the magnetic field sensing signal output by the Hall sensor. The main control unit can calculate the load change based on the amplitude of the signal change and compare it with a preset threshold to determine the presence or absence of the target being carried and its weight range.

[0088] This embodiment uses a Hall sensor to achieve non-contact, high-precision detection without direct contact with the load. It also has the advantages of being dustproof, moisture-proof, and durable, making it suitable for long-term operation in outdoor environments.

[0089] In one embodiment, the detection device 12 is a pressure sensor; the pressure sensor can be a strain gauge type, piezoresistive type or capacitive force sensor, which outputs an electrical signal proportional to the load.

[0090] Specifically, the pressure sensor is placed on the load-bearing path. Through calibration, the electrical signal can be converted into a weight value. Combined with filtering and temperature drift compensation algorithms, the measurement stability in outdoor environments is improved.

[0091] This application further proposes a main control unit configured to compare the detected pressure value with a preset threshold range: when the pressure value is within the threshold range, a shooting signal is sent to the camera unit 3; when the pressure value exceeds the upper limit of the threshold range, the driving device 11 is controlled to work.

[0092] In practice, the main control unit is a circuit system that integrates sensor signal acquisition and the coordinated operation of various control execution components, including an embedded processor, sensor signal input interface, device component control signal output interface, and related electronic circuits.

[0093] In one embodiment, the threshold range is set to 20g to 200g to distinguish the difference in load-bearing capacity between birds landing and larger animals stepping on them.

[0094] In one embodiment, when the detected pressure value is in the range of 20g to 200g, the main control unit sends a shooting signal to the camera unit 3 to capture images or videos of birds visiting.

[0095] In one embodiment, when the detected pressure value is greater than 200g, the main control unit controls the repelling device 11 to work, causing the repelling device 11 to spray a repelling mist formed by 10mL of peppermint oil and 50g of sulfur powder, or at the same time emit a sound wave signal of a preset frequency to repel non-target animals such as squirrels.

[0096] In one embodiment, when the detected pressure value is less than 20g, the main control unit does not trigger the operation of the camera unit 3 and the driving device 11 to avoid false triggering caused by minor disturbances such as fallen leaves, raindrops or small insects.

[0097] This application further proposes that a power supply unit is also included, which is used to provide power to the birdwatching device.

[0098] The power supply unit can be a rechargeable battery pack, and can be equipped with a Type-C power interface or a solar power module to achieve multi-source power supply.

[0099] In one embodiment, the birdwatching device further includes a power supply interface connected to a power supply circuit for charging the device's internal battery via an external power adapter, power bank, or solar panel. The power supply interface can be a standard interface such as USB Type-C, Micro USB, or a DC power strip, and can be optionally equipped with a waterproof and dustproof structure to adapt to outdoor environments.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
