Description

Technical Field

[0002] At present, many families are willing to feed pets, which not only adds to the fun of life, but also serves as an emotional sustenance. However, due to the accelerated pace of life, people often have to go out early and come back late or work overtime, so they often have no time to take care of their pets' three meals a day. If they give food to their pets all at once before going out in the morning, pets often eat without restraint or overturn the food bowl, wasting food. Sometimes they need to go out for several days, but when the owner is out, no one will take care of the pet. The general way to deal with it is to entrust the pet to foster care, which is ideal for longer-term outings. For breeders who are away for a short period of time, the cost of entrusting the pet to foster care is too high, but if they do not entrust the pet to foster care, the problem of feeding the pet becomes a problem that needs to be considered.

[0003] The current pet feeders use the principle of gravity. The more food the pet eats, the more food will flow out, causing food contamination or the pet to be oversatiated. Some pets even spill food and water when they are not eating, causing poor hygiene on the surrounding ground.

[0045] A baffle plate 9 is provided in the lower box body 1 , and an ultraviolet sterilization lamp 10 is provided on one side of the top baffle plate 9 of the lower box body 1 .

[0046] When the utility model is implemented, when in use, firstly, the controller 3 is used to set the program, set the feeding time, feeding amount, cleaning, sterilization, etc.;

[0047] When feeding is needed, the controller 3 controls the feeding motor 4-2 to rotate, and then drives the feeding hopper 4-1 to rotate through the toothed belt. When the feeding port 4-8 and the discharge port 4-5 are aligned, the food falls from the discharge port 4-5 and the feeding port 4-8 into the feeding hopper 4-1, and then falls into the cavity on the left side of the dining plate 5-2.

After completion, the controller 3 controls the drawer motor 5-4 to rotate. The rotation of the drawer motor 5-4 will drive the rack 5-3 to move through the second gear 5-9, and then drive the drawer 5-1 to move out of the lower box 1 along the slide rail 5-7, so that the pet can eat food and drink water; the camera 8 can take real-time photos of the movement of the drawer 5-1, and transmit the position signal of the signal drawer 5-1 to the controller 3 in real time. When the drawer 5-1 moves to a certain position, the controller 3 controls the drawer motor 5-4 to stop;

[0048] When the set feeding time is up, the controller 3 controls the drawer motor 5-4 to rotate, driving the drawer 5-1 along the slide rail 5-7 back to the lower box body 1. When the drawer 5-1 moves into the lower box body 1, the controller 3 controls the servo motor 6-1 and the cleaning motor 6-2 to rotate, driving the fixed plate 6-4 to rotate downward with the mechanism on the fixed plate 6-4. The camera 8 can transmit the position of the roller 6-3 and the bristles 6-6 in real time. When the bristles 6-6 touch the dining plate 5-2, the servo motor 6-1 is controlled to stop, and the cleaning motor 6-2 will drive the roller 6-3 and the bristles 6-6 to rotate. As the drawer 5-1 moves, the remaining food in the drawer 5-1 will be swept to the outside of the drawer 5-1, and finally swept into the residue recovery chamber 5-5 of the drawer 5-1. The speed of the cleaning motor 6-2 can be set by the controller 3, so that the bristles 6-6 will not sweep the food to the ground due to too fast a speed when cleaning;

[0049] Then, the meal plate lifting motor 5-10 is started and controlled to rotate 90 degrees, driving the diamond support plate 5-11 to rotate 90 degrees. The diamond support plate 5-11 will support one end of the meal plate 5-2, so that the meal plate 5-2 forms a slope. Then, the solenoid valve 7-2 on the pipeline between the water spray pipe body 7-1 and the three-way joint 7-4 is controlled to open, and water is sprayed onto the meal plate 5-2 through the water spray hole on the water spray pipe body 7-1, thereby achieving the purpose of cleaning the meal plate 5-2. After cleaning, the meal plate lifting motor 5-10 is controlled to rotate 90 degrees, the meal plate 5-2 is laid flat, and then the ultraviolet sterilization lamp 10 is started to sterilize the meal plate 5-2. After sterilization, the equipment is in standby state, waiting for the next feeding.
