Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and in particular to automatic pet feeders and precision feeding control systems. Background Technology

[0002] Automatic pet feeders, as devices that can automatically dispense food to pets, solve the problem of pet owners being unable to feed their pets on time due to busy work schedules or travel, greatly facilitating the pet-raising process. Most current automatic pet feeders can only dispense a fixed amount of food at preset times. Since a pet's appetite is influenced by various factors, causing their condition to constantly change, a fixed amount of food cannot meet their actual needs. This results in either excessive food residue, leading to waste and potential spoilage if left unattended, affecting the pet's food safety; or insufficient food, leaving the pet hungry, which can negatively impact their growth, development, and health in the long run. Therefore, existing automatic feeders lack a targeted feeding adjustment mechanism, making it difficult to ensure the pet's health. Furthermore, most existing automatic pet feeders lack the ability to detect the pet's individual condition. When health problems arise, they cannot alert the owner through abnormalities during feeding, making it difficult for the owner to detect potential health issues in time and potentially causing them to miss the optimal treatment window, thus presenting limitations. The reason for this problem is that existing automatic pet feeders cannot sense changes in a pet's actual appetite in real time. Existing automatic feeders can only mechanically execute preset feeding instructions and cannot monitor and judge these dynamic factors that affect appetite. More importantly, because existing devices lack the ability to distinguish and analyze these situations, they cannot correlate feed residue information with the pet's health status. This makes it impossible for pet owners to obtain health warning information for their pets through automatic feeders, making it difficult to meet pet owners' needs for pet health management. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic pet feeder and a precise feeding control system to solve the problems of existing automatic pet feeders being unable to adjust the feeding amount according to changes in the pet's own condition, resulting in excessive or insufficient feed residue, affecting the pet's health, causing feed waste, and failing to alert the owner in advance of abnormal situations during the feeding process, making it difficult to ensure the pet's health.

This device, through the installation of a monitoring unit, can acquire real-time data on the pet's weight and the amount of food residue in the food bowl. The control component dynamically adjusts the feeding amount based on this data, breaking the limitations of existing automatic feeders that only provide quantitative feeding. Whether the pet's appetite fluctuates due to growth, exercise, or seasonal changes, or changes in appetite due to slight discomfort, the device can adjust the feeding amount accordingly to avoid excessive or insufficient food residue.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: This invention provides, for example Figures 1 to 3 The automatic pet feeder and precision feeding control system shown includes a body 1, a food bowl 2 on one side of the body 1, and a monitoring unit 3 on one side of the body 1. The monitoring unit 3 includes a vision lens 31, a leftover food weighing device 32, and a pet weighing device 33. The visual lens 31 is fixedly assembled with the body 1. The visual lens 31 is used to photograph the food left inside the food bowl 2. The leftover food weighing device 32 is set inside the food bowl 2. The leftover food weighing device 32 is used to weigh the food inside the food bowl 2. The pet weighing device 33 is rotatably connected to one side of the body 1. The pet weighing device 33 is used to weigh the pet. A control component 4 is provided on one side of the device 1. The control component 4 is electrically connected to the monitoring unit 3. The control component 4 achieves accurate monitoring of the pet's weight and the amount of food residue in the food bowl 2 through the monitoring unit 3. It sets an initial feeding threshold based on the pet's weight, and then comprehensively analyzes the feeding time and the amount of food residue during each feeding to dynamically adjust the feeding amount for the next feeding. Finally, by continuously recording the data of three meals, it achieves differentiated feeding based on the pet's eating patterns.

[0030] The leftover material weighing device 32 includes a first pressure plate 321 and a pressure sensor 322; the first pressure plate 321 is disposed inside the food bowl 2; the pressure sensor 322 is fixedly mounted on the inner bottom of the food bowl 2, and the pressure sensor 322 is fixedly mounted to the first pressure plate 321. The pet weighing device 33 includes a flip plate 331 and a second pressure plate 332; the second pressure plate 332 is disposed on one side of the flip plate 331, and a weighing sensor is disposed inside the flip plate 331, and the weighing sensor is fixedly mounted to the second pressure plate 332; elastic shock-absorbing pads are disposed at the bottom of the first pressure plate 321 and the second pressure plate 332.

[0031] In this embodiment, the vision lens 31 is used to photograph the feed remaining inside the food bowl 2, and to accurately determine the remaining feed in the food bowl 2 through image recognition technology. It can also be used to capture images of nearby pets to assist in pet identity verification. The feed weighing device 32 is installed inside the food bowl 2 and is used to weigh the feed inside the food bowl 2 to accurately obtain real-time weight data of the feed, providing a weight basis for adjusting the feeding amount. The pet weighing device 33 is used to weigh the pet and monitor the pet's weight changes in real time, providing basic data for setting a safe feeding amount threshold.

[0032] When the feed is placed on the first pressure plate 321, the first pressure plate 321 transmits pressure to the pressure sensor 322. The pressure sensor 322 converts the pressure signal into an electrical signal and transmits it to the control component 4, thereby achieving accurate measurement of the feed weight. The elastic shock-absorbing pad is made of silicone material, which can effectively absorb pressure impact and reduce the impact of vibration generated when the pet eats or stands on the sensor measurement accuracy. At the same time, it can also reduce noise and improve the user experience of the equipment. The rotary motor 36 works under the control of the control component 4, driving the flip plate 331 to rotate, realizing the unfolding and retraction of the pet weighing device 33. In the non-weighing state, the flip plate 331 can be retracted to reduce the space occupied by the equipment.

[0033] Example 2: like Figure 1 , Figure 4 The automatic pet feeder and precision feeding control system shown includes a body 1, a food bowl 2 on one side of the body 1, and a monitoring unit 3 on one side of the body 1. The monitoring unit 3 includes a vision lens 31, a leftover food weighing device 32, and a pet weighing device 33. The visual lens 31 is fixedly assembled with the body 1. The visual lens 31 is used to photograph the food left inside the food bowl 2. The leftover food weighing device 32 is set inside the food bowl 2. The leftover food weighing device 32 is used to weigh the food inside the food bowl 2. The pet weighing device 33 is rotatably connected to one side of the body 1. The pet weighing device 33 is used to weigh the pet. A control component 4 is provided on one side of the device 1. The control component 4 is electrically connected to the monitoring unit 3. The control component 4 achieves accurate monitoring of the pet's weight and the amount of food residue in the food bowl 2 through the monitoring unit 3. It sets an initial feeding threshold based on the pet's weight, and then comprehensively analyzes the feeding time and the amount of food residue during each feeding to dynamically adjust the feeding amount for the next feeding. Finally, by continuously recording the data of three meals, it achieves differentiated feeding based on the pet's eating patterns.

[0034] S1. Identity and weight confirmation: When the pet approaches during feeding time, the pet weighing device 33 flips over and measures its current weight. Simultaneously, the visual camera 31 performs image recognition to verify the pet's identity, ensure that it is the correct feeding target, and generate a safe feeding amount threshold. S2. Execute the baseline feeding. According to the currently set feeding amount, the discharge motor inside the controller body 1 starts to work and puts the predetermined amount of feed into the feeding trough 2. S3. Monitor the feeding process. The system records the start time of feeding and continuously monitors the remaining food in the food bowl 2 through the visual lens 31 until the pet leaves, and records the end time. S4. Calculate key indicators. The system calculates the average feeding speed and feed residue rate based on the feeding time and the remaining weight in the bowl. S5. Determine the feeding status. The system will compare the calculated feeding speed and feed residue rate with the preset normal range values ​​to determine whether the feeding is insufficient, normal or excessive. S6. Perform real-time adjustments. If the system determines that the feed is insufficient, it will immediately start the feed motor to supplement the feed. However, the total amount of feed given this time will not exceed the safe feeding threshold set for the pet. S7. Adjust subsequent feeding amount. Based on the judgment result, the system dynamically adjusts the feeding amount threshold for the pet's next meal to achieve precise feeding based on appetite. S8. Perform long-term trend recording. The system archives the feeding data for each day, including time, feeding amount, feed intake, and residual amount, forming a long-term database. Based on the database, the system generates the initial value of the feeding amount for each meal in S2. S9. Activate the health early warning mechanism, systematically analyze long-term data trends, and immediately send an alarm to the owner if a sudden change in food intake or weight is detected that exceeds the normal fluctuation range.

[0035] In this embodiment, at the set feeding time, when the pet approaches the feeder, the control component 4 controls the rotary motor 36 to operate, driving the flip plate 331 to rotate to a horizontal state, causing the pet weighing device 33 to unfold, and the pet to stand on the second pressure plate 332. The weighing sensor inside the pet weighing device 33 measures the pet's current weight. Simultaneously, the vision lens 31 synchronously captures images of the pet and compares the captured images with pet images pre-stored in the data storage module of the control component 4 to complete pet identity verification and ensure that the feeding object is correct. Based on the verified pet identity and its current weight, combined with preset parameters such as the pet's breed and age, the control component 4 uses a built-in algorithm to generate the safe feeding threshold for the pet this time. The control component 4 sends a control command to the dispensing motor inside the feeder 1 according to the currently set feeding amount for the pet. The dispensing motor starts working and drives the feeding structure inside the feeder through the transmission mechanism, dispensing the predetermined amount of feed into the feeding bowl 2. After the feed is dispensed, the control component 4 records the feeding start time. During this process, the vision lens 31 continuously captures images of the feeding bowl 2, using image recognition technology to monitor the remaining feed in the feeding bowl 2 in real time. At the same time, it combines the weight data fed back by the residual feed weighing device 32 to double confirm the amount of feed remaining. Until the vision lens 31 detects that the pet has left the feeding area, the control component 4 records the feeding end time. The control component 4 calculates the total feeding amount based on the recorded feeding start and end times. The system calculates the actual feed intake based on the weight of the initial feed given and the weight of the remaining feed after feeding, measured by the feed weighing device 32. Then, it calculates the average feeding speed by the ratio of the actual feed intake to the feeding time. Finally, it calculates the feed residue rate by the ratio of the remaining feed weight to the initial feed weight. The control component 4 compares the calculated feeding speed and feed residue rate with the normal feeding speed range and normal feed residue rate range for that pet breed, pre-stored in the data storage module. If the feeding speed is below the lower limit of the normal range and the feed residue rate is above the upper limit of the normal range, then the feeding is considered insufficient. If both the feeding speed and feed residue rate are within the normal range, then... If the current feeding is deemed normal, and the feeding speed is higher than the upper limit of the normal range while the feed residue rate is lower than the lower limit of the normal range, then the current feeding is deemed excessive. If the result indicates insufficient feed, the control component 4 immediately sends a supplementary feeding command to the discharge motor to start supplementary feeding. During the supplementary feeding process, the control component 4 monitors the total feeding amount in real time through the residual feed weighing device 32 to ensure that the total feeding amount does not exceed the safe feeding threshold set for the pet, thus avoiding overfeeding. Based on the current feeding status, the control component 4 dynamically adjusts the feeding threshold for the pet's next meal. If the current feeding is insufficient, the feeding threshold for the next meal can be appropriately lowered; if the current feeding is normal, the feeding threshold for the next meal remains unchanged.If the pet overeats in a given meal, the feeding threshold for the next meal can be appropriately increased, thus achieving precise feeding based on the pet's real-time appetite. Control component 4 automatically archives the daily feeding data to the data storage module, forming a long-term feeding database for the pet. When setting the initial feeding amount each time, control component 4 calls upon historical data from the long-term feeding database and analyzes the pet's eating patterns under similar weight conditions and time periods using algorithms. This generates the initial feeding amount for each meal in S2, making the initial feeding amount more aligned with the pet's dietary habits. Control component 4 periodically performs trend analysis on the data in the long-term feeding database, calculating the weekly and monthly rate of change in the pet's weight, as well as the weekly and monthly fluctuations in feeding amount. If it is found that the pet's food intake decreases or increases sharply within a short period, exceeding the normal fluctuation range, or its weight increases or decreases sharply within a short period, exceeding the normal fluctuation range, it is determined that the pet may have a health problem. Control component 4 immediately sends an alarm message to the pre-bound owner's mobile phone via the Wi-Fi module. The alarm message includes details of the abnormal data and potential health risk warnings, reminding the owner to pay attention to the pet's health status.

[0036] Example 3: like Figure 1 , Figure 5 , Figure 6 and Figure 7 The automatic pet feeder and precision feeding control system shown includes a body 1, a food bowl 2 on one side of the body 1, and a monitoring unit 3 on one side of the body 1.
