[0001] This application belongs to the field of power supply technology, and more specifically, relates to a feeding device. Background Technology

[0002] With the improvement of people's living standards and technological levels, some intelligent feeding devices have been introduced to the market.

The compartment door can also automatically open to allow the pet to access the food. This saves labor and improves the convenience of pet feeding.

[0003] In related technologies, feeding devices generally require a power source to operate. That is, the feeding device's power adapter is electrically connected to an external power source, which supplies power to the feeding device so it can function intelligently.

[0050] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments:

[0051] Please see Figure 1 The feeding device provided in this embodiment includes a feeding structure 10, a control component 20, a battery 30, and a power adapter 40. The control component 20 is disposed on the feeding structure 10 and electrically connected to it. The battery 30 is disposed on the feeding structure 10 and electrically connected to the control component 20. The power adapter 40 is connected to the feeding structure 10 and electrically connected to the control component 20, and is used for electrical connection to an external power source. When the power adapter 40 provides normal power to the control component 20, the control component 20 controls the circuit between the battery 30 and the control component 20 to disconnect; when the power adapter 40 provides abnormal power to the control component 20, the control component 20 controls the circuit between the battery 30 and the control component 20 to connect.

[0052] The feeding structure 10 refers to a structure used for feeding pets. The feeding structure 10 can operate intelligently when powered on. For example, when powered on, the food storage compartment within the feeding structure 10 can automatically dispense food. Also, when powered on, the compartment door of the feeding structure 10 can automatically open, allowing the pet to access the food at the compartment door.

[0053] The power adapter 40 refers to an electrical connector used for connecting to an external power source. The external power source can be a power grid, generator, or other structure or system that outputs power. The power adapter 40 can be connected to the feeding structure 10 via a conductive structure such as a charging cable; alternatively, the power adapter 40 can be directly integrated into the feeding structure 10.

[0054] The battery 30 is a device capable of storing and outputting power. The battery 30 may include cylindrical batteries, prismatic batteries, button batteries, etc. The battery 30 can be a lithium battery, a dry cell battery, etc. The battery 30 is used to power the control component 20 and the feeding structure 10.

[0055] Control component 20 refers to a component structure with control functions.

[0056] It should be noted that "power adapter 40 providing normal power to control component 20" means that power adapter 40 can normally supply power to control component 20. Specifically, when power adapter 40 provides normal power to control component 20, control component 20 can disconnect the circuit between battery 30 and control component 20, so that battery 30 will not supply power to control component 20 or feeding structure 10; that is, control component 20 will not control battery 30 to supply power to feeding structure 10. Thus, by electrically connecting power adapter 40 to an external power source, power adapter 40 can supply power to both control component 20 and feeding structure 10. Specifically, when power adapter 40 provides normal power to control component 20, power adapter 40 can supply power to feeding structure 10 under the control of control component 20, or it can supply power to feeding structure 10 independently.

[0057] It should also be noted that a power adapter 40 supplying power to the control component 20 malfunctions, meaning the power adapter 40 cannot normally supply power to the control component 20. This can include situations such as an external power outage, a damaged power adapter 40, or the power adapter 40 being unable to connect to an external power source. When the power adapter 40 is supplying power to the control component 20, it will not supply power to either the control component 20 or the feeding structure 10. However, even when the power adapter 40 is supplying power to the control component 20, the control component 20 can still maintain the circuit connection between the battery 30 and itself. This allows the control component 20 to control the battery 30 to supply power to both itself and the feeding structure 10. It is worth noting that when the power adapter 40 is supplying power to the control component 20, the power adapter 40 experiences a power-down process. When the control component 20 detects the power loss, it can use its remaining power to control the circuit between the battery 30 and itself, thus controlling the battery 30 to supply power to both the control component 20 and the feeding structure 10.

[0058] The feeding device provided in this embodiment includes a control component 20, a battery 30, and a power adapter 40 on the feeding structure 10. Both the battery 30 and the power adapter 40 are electrically connected to the control component 20. When the power adapter 40 is electrically connected to an external power source and supplies power to the control component 20 normally, the control component 20 can disconnect the circuit between the battery 30 and the control component 20, allowing the power adapter 40 to supply external power to the feeding structure 10, enabling it to operate intelligently. In cases of power outages, power adapter 40 malfunction, or inability to connect to an external power source, the control component 20 can restore the circuit between the battery 30 and the control component 20, allowing the battery 30 to supply power to the feeding structure 10, thus enabling it to continue operating intelligently. This improves the ease of use of the feeding device.

[0059] It should be further explained that when the power adapter 40 is supplying power normally, it powers the feeding mechanism 10; when the power adapter 40 is malfunctioning, the battery 30 powers the feeding mechanism 10. Thus, the power adapter 40 and the battery 30 will not supply power simultaneously. That is, when the power adapter 40 is supplying power normally, the circuit between the battery 30 and the control component 20 is not working, and the battery 30 will not supply power. This serves two purposes: firstly, it protects the circuit between the battery 30 and the control component 20, extending the battery 30's lifespan; secondly, it prevents the power adapter 40 from supplying power to the battery 30, thereby improving the problem of the feeding mechanism 10 not being able to receive power in a timely manner.

[0060] In some embodiments, please refer to Figure 1 The control component 20 includes a control unit 21 and a power supply module 22. The control unit 21 is mounted on the feeding structure 10 and is used to control the feeding structure 10. The power supply module 22 is electrically connected to the control unit 21, the power adapter 40, and the battery 30.

[0061] The control unit 21 may be, but is not limited to, a microcontroller, and has processing and control capabilities. Specifically, the control unit 21 is electrically connected to the feeding structure 10 and is used to control the feeding structure 10.

[0062] Power supply module 22 refers to the circuit module used for power supply.

[0063] The circuit between the battery 30 and the control component 20 is the circuit between the battery 30 and the power supply module 22.

[0064] Understandably, when the power adapter 40 is supplying power normally, the control unit 21 can disconnect the circuit between the battery 30 and the power supply module 22, allowing the power adapter 40 to supply power to the power supply module 22, so that the power supply module 22 outputs the power provided by the power adapter 40 to the feeding structure 10, thereby achieving the effect of the power adapter 40 supplying power to the feeding structure 10. When the power adapter 40 is supplying power abnormally, the control unit 21 can connect the circuit between the battery 30 and the power supply module 22, allowing the control unit 21 to control the battery 30 to supply power to the power supply module 22, so that the power supply module 22 outputs the power provided by the battery 30 to the feeding structure 10, thereby achieving the effect of the battery 30 supplying power to the feeding structure 10.

[0065] This configuration allows the control component 20 to control the battery 30 to supply power to the feeding structure 10 when the power adapter 40 fails to provide power.

[0066] In some embodiments, please refer to Figure 1 The feeding device also includes a first switch 50, which is located in the circuit between the battery 30 and the power supply module 22. The control unit 21 controls the first switch 50 to open or close. When the first switch 50 is open, the circuit between the battery 30 and the power supply module 22 is disconnected. When the first switch 50 is closed, the circuit between the battery 30 and the power supply module 22 is connected.

[0067] The first switch 50 is a switch structure. Understandably, the first switch 50 is located between the output terminal of the battery 30 and the input terminal of the power supply module 22.

[0068] Understandably, the control unit 21 can control the first switch 50 to close, thereby connecting the circuit between the battery 30 and the power supply module 22. In this way, the battery 30 can supply power to the power supply module 22, allowing the control unit 21 to control the power output from the battery 30 to the power supply module 22 to the feeding structure 10. For example, in cases of power adapter 40 power failure, damage, or inability to connect to an external power source, the control unit 21 can control the first switch 50 to close.

[0069] The control unit 21 can also control the first switch 50 to open, thereby disconnecting the circuit between the battery 30 and the power supply module 22. This prevents the battery 30 from supplying power to the power supply module 22. For example, when the power adapter 40 is supplying power normally, the control unit 21 can control the first switch 50 to open.

[0070] By setting the first switch 50, the control unit 21 can control the connection or disconnection of the circuit between the battery 30 and the power supply module 22.

[0071] In some embodiments, please refer to Figure 1 The feeding device also includes a first power detection module 60, which is electrically connected between the power adapter 40 and the control unit 21. The first power detection module 60 is used to detect the power supply status of the power adapter 40. Specifically, when the first power detection module 60 detects an abnormal power supply from the power adapter 40, the control unit 21 controls the first switch 50 to close. When the first power detection module 60 detects a normal power supply from the power adapter 40, the control unit 21 controls the first switch 50 to open.

[0072] The first power supply detection module 60 is a module used to detect the circuit status between the power adapter 40 and the power supply module 22 to obtain the power supply status of the power adapter 40. It can be a circuit module for detecting power supply. Specifically, the first power supply detection module 60 can be used to detect the voltage of the circuit between the power adapter 40 and the power supply module 22 to obtain the power supply status of the power adapter 40.

[0073] Specifically, the input terminal of the first power detection module 60 is electrically connected to the output terminal of the power adapter 40, and the output terminal of the first power detection module 60 is electrically connected to the control unit 21.

[0074] Understandably, when the first power detection module 60 detects an abnormal power supply from the power adapter 40, it indicates a power supply failure, a damaged power adapter 40, or an inability of the power adapter 40 to connect to an external power source. In this case, the power adapter 40 cannot supply power to the feeding structure 10. Based on this, the control unit 21 controls the first switch 50 to close, allowing the battery 30 to supply power to the power supply module 22, thus ensuring timely power supply to the feeding structure 10.

[0075] When the first power detection module 60 detects that the power adapter 40 is supplying power normally, the power adapter 40 can supply power to the feeding structure 10 normally. Based on this, the control unit 21 controls the first switch 50 to open, so as to prevent the battery 30 and the power adapter 40 from supplying power at the same time, and to prevent the power adapter 40 from supplying power to the battery 30, which would cause the feeding structure 10 to fail to be powered in time.

[0076] By adopting the above technical solution, the feeding structure 10 achieves an intelligent power-on effect.

[0077] In some embodiments, the first switch 50 is a normally open switch.

[0078] Understandably, when the control unit 21 does not control the first switch 50, the first switch 50 is in the open state, and the circuit between the battery 30 and the power supply module 22 remains disconnected. That is, in the initial state, the first switch 50 is open, and the circuit between the battery 30 and the power supply module 22 is disconnected.

[0079] This configuration ensures that, in its initial state, the feeding device tends to use the power adapter 40 to power the power supply module 22, while the battery 30 remains as a backup. This simplifies the control circuitry of the control unit 21 for the battery 30 and helps extend the battery's lifespan.

[0080] In some embodiments, please refer to Figure 1 The feeding device also includes a second power detection module 70, which is electrically connected between the battery 30 and the control unit 21, and is used to detect the power supply status of the battery 30. When the second power detection module 70 detects an abnormal power supply to the battery 30, the control unit 21 controls the first switch 50 to open.

[0081] The second power supply detection module 70 is a module used to detect the circuit status between the battery 30 and the power supply module 22 to obtain the power supply status of the battery 30. It can be a circuit module for detecting power supply. Specifically, the second power supply detection module 70 can be used to detect the voltage of the circuit between the battery 30 and the power supply module 22. In particular, the second voltage detection module is used to detect the voltage of the circuit between the battery 30 and the first switch 50 to obtain the power supply status of the battery 30.

[0082] The input terminal of the second power detection module 70 is electrically connected to the output terminal of the battery 30. Specifically, the input terminal of the second power detection module 70 is electrically connected between the output terminal of the battery 30 and the first switch 50, and the output terminal of the second power detection module 70 is electrically connected to the control unit 21.

[0083] Understandably, when the second power detection module 70 detects an abnormal power supply to the battery 30, it indicates that the battery 30 is damaged or has insufficient power, thus preventing the battery 30 from supplying power to the feeding structure 10. Based on this, the control unit 21 controls the first switch 50 to open, thereby protecting the circuit between the battery 30 and the power supply module 22.

[0084] When the second power detection module 70 detects that the battery 30 is supplying power normally, the battery 30 can supply power to the feeding structure 10 normally. Based on this, the control unit 21 can control the first switch 50 to close as needed, so that the battery 30 supplies power to the feeding structure 10.

[0085] By adopting the above technical solution, the control unit 21 can control whether the battery 30 supplies power to the feeding structure 10 according to the power supply status of the battery 30.

[0086] In some embodiments, the feeding device may further include a reminder structure disposed on the feeding structure 10 and electrically connected to the control unit 21. When the second power detection module 70 detects an abnormal power supply from the battery 30, the control unit 21 controls the reminder structure to issue a prompt.

[0087] The reminder structure may include at least one of an audible reminder structure and an illuminated reminder structure. The audible reminder structure may include at least one of a buzzer and a speaker.

[0088] When the second power detection module 70 detects an abnormal power supply to the battery 30, the control unit 21 can also control the reminder structure to provide a prompt so that the feeding device can replace the battery 30.

[0089] In some embodiments, please refer to Figure 1 The feeding device also includes a second switch, which is located in the circuit between the power adapter 40 and the power supply module 22. The control unit 21 controls the second switch to open or close. When the second switch is open, the circuit between the power adapter 40 and the power supply module 22 is disconnected. When the second switch is closed, the circuit between the power adapter 40 and the power supply module 22 is connected.

[0090] The second switch is a switch structure. Understandably, the second switch is located between the output terminal of the power adapter 40 and the input terminal of the power supply module 22.

[0091] Understandably, the control unit 21 can control the second switch to close, thereby connecting the circuit between the power adapter 40 and the power supply module 22. In this way, the power adapter 40 can supply power to the power supply module 22, so that the control unit 21 controls the power adapter 40 to output power to the power supply module 22 to the feeding structure 10; that is, the control component 20 controls the power adapter 40 to supply power to the feeding structure 10.

[0092] The control unit 21 can also control the second switch to open, thereby disconnecting the circuit between the power adapter 40 and the power supply module 22, so that the power adapter 40 cannot supply power to the power supply module 22. For example, in the event of an abnormal power supply to the power adapter 40, such as an external power outage, a damaged power adapter 40, or the power adapter 40 being unable to connect to an external power source, the control unit 21 can control the second switch to open, which helps to protect the circuit between the power adapter 40 and the power supply module 22.

[0093] In some embodiments, the second switch is a normally closed switch.

[0094] Understandably, when the control unit 21 does not control the second switch, the second switch is in the closed state, and the circuit between the power adapter 40 and the power supply module 22 remains connected. That is, in the initial state, the second switch is closed, and the circuit between the power adapter 40 and the power supply module 22 is connected.

[0095] This configuration causes the feeding device to initially use the power adapter 40 to power the power supply module 22, while the battery 30 remains as a backup.

[0096] In some embodiments, please refer to Figure 1 The feeding structure 10 includes a chamber, a drive unit, and a door. The chamber has an outlet, the drive unit is mounted on the chamber and electrically connected to the control assembly 20. The door is located at the output end of the drive unit, which drives the door to open or close the outlet.

[0097] The feeding chamber is the main structure of the feeding structure 10. Understandably, the power adapter 40, battery 30, and control components 20 are all located on the feeding chamber.

[0098] The drive unit refers to the device used to drive the movement of the compartment door. Specifically, the drive unit is electrically connected to the control unit 21.

[0099] Understandably, the door is movably connected to the compartment body. The drive unit is used to move the door relative to the compartment body, so as to open or close the outlet.

[0100] With this configuration, when the power adapter 40 or the battery 30 supplies power to the feeding structure 10, specifically when the power adapter 40 or the battery 30 supplies power to the drive device, the chamber door moves under the drive of the drive device, thereby opening the outlet.

[0101] In some embodiments, the control component 20 may further include a drive module 23, which is electrically connected between the drive device and the control unit 21. The drive module 23 may be a circuit module for controlling the drive device.

[0102] Under the control of the control unit 21, the drive module 23 drives the drive device to open the compartment door.

[0103] In some embodiments, the bin door is rotatably connected to the bin body.

[0104] Understandably, the door can rotate relative to the compartment body under the drive of the drive device to open or close the outlet.

[0105] This setup simplifies the structure of the feeding structure 10.

[0106] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
