[0036] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0037] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0038] As people's material living standards improve, their pursuit of spiritual life is also increasing. Raising pets can enrich people's spiritual life and bring them happiness and companionship. Therefore, raising pets has become the choice of more and more people, and the convenience of feeding has become a concern for people when raising pets.

[0039] Typically, pets are fed a single serving of food, which is the amount of food they eat at each meal. This method requires manual feeding at each meal, which is quite cumbersome. Furthermore, if a large amount of food is fed at once, it may be affected by the environment and may cause mold, which is detrimental to the pet's health.

[0040] In order to solve the above problems, the present application embodiment proposes a pet feeder, such as Figure 1As shown, the pet feeder includes a food storage space 10, a refrigeration module 20, a food trough 30 and a control module 40. The food storage space can be used to store a large amount of food. The food storage space can be provided with a discharge port 101, which can be used to deliver food to the food trough 30. The discharge port can be controlled by the control module 40, including controlling it to be in an open state, and the food in the food storage space 10 can be delivered to the food trough 30 through the discharge port 101. When the discharge port 101 is in a closed state, the food storage space 10 is in a sealed state. The food storage space 10 may include structures such as a cavity.

[0041] The refrigeration module 20 can lower the temperature in the food storage space 10. The refrigeration module can include, for example, a mechanical refrigeration device (e.g., a compression-type cooling device), a semiconductor refrigeration device, or an electronic refrigeration chip. The refrigeration module 20 can be controlled to operate or shut down via control signals output by the control module 40. Pre-commissioning can determine the duration of the refrigeration module's on and off state during a control cycle when the food storage space 10 is at different temperatures.

[0042] The food trough 30 can be used to receive food delivered from the food storage space 10 so that the pet can eat it according to the set meal time.

[0043] The control module 40 can control the cooling module 20 to operate in different modes based on the pet's mealtime or feeding schedule. For example, multiple cooling gears can be pre-set, each with a corresponding on-time and off-time for the cooling module 20 during a control cycle. The corresponding gear can be selected based on the pet's feeding schedule or according to user input.

[0044] In a possible implementation, the pet feeder may further include a heat dissipation module for dissipating the heat absorbed by the refrigeration module.

[0045] Figure 2 A schematic diagram of a temperature control method for a pet feeder according to an embodiment of the present application is provided, as detailed below:

[0046] In S201, the feeding time of the pet feeder is obtained.

[0047] The feeding time of the pet feeder in the embodiment of the present application can be determined according to the feeding plan set by the user. For example, the user sets the feeding time of the pet feeder to twice a day or three times a day. If the feeding plan is set to twice a day, the feeding times are 9:00 am and 5:00 pm respectively. If the feeding plan is set to three times a day, the feeding times are 8:00 am, 12:00 pm, and 6:00 pm respectively. The feeding time of the pet can be obtained according to the feeding plan.

[0048] In a possible implementation, feeding can be performed according to a user's feeding instruction. For example, the user can generate a feeding instruction using a feeding button on the pet feeder, or the user can send a feeding instruction to the pet feeder via a smart terminal that has established a communication connection with the pet feeder. The time when the pet feeder receives the feeding instruction can be determined as the feeding time.

[0049] In S202, a time range corresponding to a cooling gear of the pet feeder is determined according to the feeding time, where the cooling gear includes an on time length and an off time length of the cooling module.

[0050] After determining the pet feeding time of the pet feeder, you can plan the cooling for different time ranges according to the feeding time of the pet feeder, so that different time periods are at different cooling gears.

[0051] For example, in one possible implementation, the pet feeder can be set to include three gears, namely the first gear, the second gear and the third gear. Among them, the first gear can change the temperature of the food storage space to a temperature close to room temperature and lower than room temperature. Figure 3 In the gear control diagram shown, when the refrigeration module controls the food storage space to be in the first gear, the on time of the refrigeration module can be made shorter than the off time within a control cycle.

[0052] When the control module controls the food storage space to be in the second gear, the difference between the on time of the refrigeration module in the second gear and the off time of the refrigeration module is less than the predetermined time threshold, that is, the difference between the on time and the off time of the refrigeration module in the second gear is small, and the temperature in the food storage space is at a medium temperature that is not frozen and is lower than the temperature corresponding to the first gear.

[0053] When the control module controls the food storage space to the third gear, the refrigeration module can remain in the on state. At this time, the temperature in the food storage space is lower, and food stored in this gear can be better preserved in the third gear compared to the first and second gears. When food is in the pre-feeding storage state, the refrigeration module of the pet feeder can be set to the third gear. During a first predetermined period before the pet is about to eat, the refrigeration module can be set to the second gear, and during a second predetermined period before the pet is about to eat, the refrigeration module can be set to the first gear. The second predetermined period is after the first predetermined period.

[0054] In a possible implementation, since different types of food have different temperature requirements, the temperature corresponding to different types of food can be set, and the temperature in the food storage space can be controlled through the first gear, second gear or third gear to meet different temperature preservation requirements.

[0055] In a possible implementation, the on-time and off-time of the refrigeration module in the first gear and the second gear may be determined according to the desired temperature.

[0056] For example, the temperature of the first gear can be set to 20 degrees and the temperature of the second gear can be set to 10 degrees. The on time and off time of the refrigeration module that need to be set when the food storage space is at this temperature can be obtained in advance through experimental data statistics.

[0057] In addition, to further improve the accuracy of temperature control, the storage capacity of the food storage space can be detected, and the on-time and off-time of the refrigeration module corresponding to the temperature can be determined according to the different storage capacities. For example, when the storage capacity of the food storage space is 1 / 2 of the entire space, the on-time of the first gear is t1 and the off-time is t2 in one control cycle. When the storage capacity of the food storage space is 1 / 3 of the entire space, the on-time of the first gear is t3 and the off-time is t4 in one control cycle. t1, t2, t3 and t4 can be different time periods.

[0058] In a possible implementation, the correspondence between different food storage amounts, different temperatures, and the on / off duration of the refrigeration module during a refrigeration cycle can be pre-set. The pet feeder can receive a temperature setting instruction, determine the current amount of food in the food storage space based on the temperature setting instruction, and determine the on / off duration of the refrigeration module during a refrigeration cycle based on the food amount and temperature.

[0059] The amount of food in the food storage space may be detected by a weight sensor, or the amount of remaining food in the food storage space may be detected by other sensing devices, including distance sensors.

[0060] In S203 , the temperature of the food storage space of the pet feeder is controlled according to the on-time and the off-time of the refrigeration module.

[0061] The refrigeration level of the refrigeration module in the food storage space is determined according to the pet's feeding time. According to the on-time and off-time of the refrigeration level in a refrigeration cycle, the temperature of the food storage space during different feeding stages can be accurately controlled, which is beneficial to improving the quality of food preservation, reducing the chance or degree of food spoilage, and improving the convenience of pet feeding.

[0062] In a possible implementation, when the refrigeration module is in the first gear, the temperature in the food storage space may drop to a low temperature, such as below zero. In this case, the food in the food storage space may freeze. In order to reduce the probability of failure in delivering food from the food storage space to the food trough, a pre-meal defrosting process can be performed within a predetermined time. Figure 4 The schematic diagram of the refrigeration module operating state shows that the refrigeration module can be controlled to stop operating within a predetermined time period before feeding time, such as 2-5 minutes before feeding time, so that the temperature of the food in the food storage space gradually rises and the food is thawed. During the pre-meal defrosting time range, the heat dissipation module can remain in operation or be controlled to be turned off.

[0063] In order to reduce the chance of food being frozen, the food can also be periodically defrosted when the pet feeder is not in a feeding state.

[0064] like Figure 4 As shown, within a feeding cycle, the time range between the completion of the kth feeding and the start of defrosting before the k+1th feeding is the periodic defrosting time range. Within the periodic defrosting time range, the refrigeration module can be deactivated for a second time period after operating for a first time period. During the second time period when the refrigeration module is deactivated, the temperature in the food storage space rises, causing the frozen food to cool down and reducing food freezing.

[0065] In an embodiment of the present application, in order to reduce the impact of the cooling module and the heat dissipation module on the pet, the cooling module and the heat dissipation module can be stopped when the pet feeder is in the feeding stage, thereby providing a quiet and comfortable dining environment for the pet.

[0066] Furthermore, the cooling module in the pet feeder of the present embodiment needs to cool the food storage space, generating a significant amount of heat during operation. To improve the reliability of the pet feeder, the temperature within the pet feeder, particularly the temperature of the cooling module, can be monitored. When the monitored temperature exceeds a predetermined threshold, the cooling module can be deactivated, reducing the risk of damage.

[0067] When the monitored temperature is greater than a predetermined temperature threshold, the heat dissipation module may fail. In order to reduce the probability of failure of the heat dissipation module, the cooling module may be stopped while the heat dissipation module is stopped.

[0068] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
