[0002] With the increasing acceleration of modern life rhythm, the work and life pressure of people is increasing, which leads to it is difficult to spend a lot of time and energy to take care of the daily life of pet. Especially for the feeding of pet, many pet owners cannot feed on time due to busy work. In order to solve this problem, pet feeder emerges as the times require. The existing pet feeder is usually equipped with feed container, main shell, automatic feeding mechanism and feeding basin and other components, which realizes the function of timed and quantitative automatic feeding, ensures that pets intake balanced nutrition, avoids overeating or malnutrition, and greatly meets the needs of pet owners in pet feeding.

[0003] However, with the development of modern technology such as Internet of Things and artificial intelligence, the original automatic feeding function of pet feeder cannot meet the needs of people. The single timed and quantitative automatic feeding function cannot monitor the alone situation and real-time feeding situation of pet and make timely adjustment, and also cannot accompany and interact with pet. Therefore, while automatically feeding pet, the alone situation and feeding situation of pet need to be monitored in real time, pet needs to be called, and pet needs to be interacted with to strengthen the emotional connection between pet and owner, so as to ensure the healthy diet of pet and improve the use experience of pet owner. In addition, the feed container of the existing automatic pet feeder generally has fixed capacity, which cannot adjust the capacity of feed container and the storage amount of standby feed according to the changes of demand such as the length of time away from home of user or the growth of pet, causing inconvenience to the selection and use of user. SUMMARY

[0004] In order to solve the technical problems in the background art, the utility model provides an automatic pet feeder, which mainly aims to solve the technical problems that the existing automatic pet feeder cannot monitor the alone situation and feeding situation of pet in real time and make timely adjustment, cannot call and interact with pet, and cannot adjust the capacity of feed container according to needs, so as to provide an automatic pet feeder which can monitor the alone situation and feeding situation of pet in real time, can call and interact with pet, and can adjust the capacity of feed container according to actual needs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
