[0002] With the improvement of people's living standards, pets have become an important member of many families. However, due to work, travel and other reasons, people are sometimes unable to provide food for their pets in time, resulting in hunger or malnutrition of pets. In addition, the preservation and hygiene of pet food is also a problem. If the food is exposed to the air, it is easy to be contaminated by bacteria, dust, etc., affecting the health of pets.

[0003] In order to solve these problems, there are some pet feeding devices that can time or remotely control the discharge of materials to provide food for pets. However, these devices still have some shortcomings. The food trays of existing pet feeding devices are usually external structures, and the food trays cannot be automatically retracted, which takes up space and is not conducive to cleaning. In addition, when the pet is fed too much or the feed is not eaten in time, bacteria may grow, affecting the freshness of the food and the health of the pet. The traditional way is to disassemble and clean the food tray, and then disinfect it. However, this method not only requires human intervention, but is also inconvenient to operate, and cannot meet the needs of pet owners for feeding their pets when they are not at home for a long time.

[0004] Therefore, it is necessary to provide a pet feeding device that can automatically discharge materials, retract the food tray and perform disinfection to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] See also Figure 1 - Figure 6 In the present embodiment, a pet feeding device is provided, which is specifically used for feeding pets when the owner is outside, and specifically comprises: an upper shell 1 and a lower shell 2, wherein the upper shell 1 is adapted with a shell cover 3, the upper shell 1 is inserted on the top of the lower shell 2, a spiral tube 4 is rotatably arranged in the lower shell 2, the end of the spiral tube 4 is connected and adapted with a first driving component 5, a discharge port 6 is provided at the other end of the lower shell 2 close to the spiral tube 4, a food tray 7 is slidably arranged below the discharge port 6 of the lower shell 2, the food tray 7 is adapted with a second driving component 8 to make it extend and retract relative to the lower shell 2, and a disinfection module 9 is arranged above the food tray 7 inside the lower shell 2.

[0025] The first driving component 5 described in this embodiment adopts a DC motor (JGA25-370-0660), and the main control MCU (HK32F030MF4P6) controls the start and stop of the first driving component 5 (the speed and direction of the DC motor can be controlled by PWM), controls the rotation of the spiral tube 4, and thus controls the discharge of food. The number of rotations of the spiral tube 4 can be controlled according to the size and appetite of the pet, thereby adjusting the discharge amount to meet the needs of different pets.

[0026] Specifically, in this embodiment, the usage of the utility model is as follows:

[0027] (1) Adding feed: Open the shell cover 3, put the feed into the upper shell 1, and then close the shell cover 3 to complete the feed replenishment operation;

[0028] (2) Disinfection before feeding: Then the lower housing 2 is powered on, and the disinfection module 9 is operated to clean the food tray 7. After cleaning, the disinfection module 9 is closed;

[0029] (3) Feeding: The second driving component 8 causes the food tray 7 to extend out of the lower shell 2. The first driving component 5 operates, driving the spiral tube 4 to rotate. The feed enters the lower shell 2 from the upper shell 1 and is transported to the discharge port 6 along the spiral tube 4, and finally falls into the food tray 7. The pet can eat after the feeding operation.

[0030] (4) Disinfection after feeding: After the pet is fed, the second driving component 8 drives the food tray 7 to retract into the lower shell 2, and the disinfection module 9 is turned on again to disinfect the food tray 7 and the residual feed therein, preparing for the next feeding.

[0031] The second driving component 8 includes a driving motor 10, a driving pulley 11 is fixed to the motor shaft of the driving motor 10, a synchronous belt 12 is meshed with the driving pulley 11, a supporting ring 13 is fixed to the side of the synchronous belt 12, and the supporting ring 13 is adapted to the protrusion 14 at the bottom of the food tray 7. By controlling the forward and reverse rotation of the driving motor 10, the movement direction of the synchronous belt 12 can be controlled, thereby controlling the extension and retraction of the food tray 7. A drawing groove 15 is provided on the front side of the food tray 7, which is convenient for users to manually draw the food tray 7. The food tray 7 is a concave structure, which is low in the middle and high around, which can prevent food from spilling and is also convenient for pets to eat.

[0032] The disinfection module 9 includes an ultraviolet lamp group 16 and a micro fan 17. The ultraviolet lamp group 16 can emit ultraviolet rays to disinfect the food tray 7 and kill bacteria on the food tray 7. The micro fan 17 can air-dry the food tray 7, remove moisture on the food tray 7, and keep the food tray 7 dry. By controlling the start or stop of the disinfection module 9, the disinfection or stop of the food tray 7 can be controlled.

[0033] The lower shell 2 is hinged with a cover plate 18 above the discharge port 6, and the cover plate 18 can cover the discharge port 6 to prevent the pet from digging out the food.

[0034] The bottom of the lower shell 2 is provided with multiple groups of suction cups 19. The side of the lower shell 2 is provided with a lifting handle 20. When the user needs to move the device, the lifting handle 20 can be used to pull the device off the ground, and then the device can be placed in another area, so that the suction cups 19 are re-adsorbed on the ground or other planes to maintain the stability of the device.

[0035] The lower housing 2 is provided with a battery 21, and a charging port 22 and a corresponding power switch 23 are provided on the rear side. The battery 21 adopts a 18650 lithium battery 21, which can provide power to the device through a voltage stabilizing circuit (AMS1117-3.3), and the main control MCU is adapted to the Internet of Things module (Tuya Smart WBR3) to achieve wireless use. When the user needs to charge the device, the device can be connected to a power source through the charging port 22 to charge the battery 21, thereby extending the service life of the battery 21 and improving the reliability of the device. When the user does not need to provide food for the pet, the device can be turned off through the power switch 23 to save power.

[0036] The lower shell 2 is provided with a buzzer 24, and a passive buzzer 24 circuit is used to prompt the pet to eat. In addition, a weighing sensor is set between the upper shell 1 and the lower shell 2, and an ADC module (CS1237 chip) is used to accurately and quickly read the data of the weighing sensor. When the feed storage in the upper shell 1 is insufficient, an alarm is sounded to prompt the pet to replenish the feed. The above method can effectively improve the intelligence of the device.

[0037] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
