Technical Field

[0001] This invention relates to the field of pet supplies technology, specifically an automatic pet feeder. Background Technology

[0002] With the increasing number of pet owners, pets can not only relieve people's work pressure, but also cultivate people's love. Now, the nutritional needs of pets are also getting higher and higher. However, most urban people are office workers who are busy with work and cannot feed their pets regularly. They often leave a lot of food for their pets when they leave in the morning. This will not only cause the pets to become obese, but also develop bad eating habits.

[0003] However, existing automatic pet feeders only feed pets and do not have the function of automatically preparing nutritional supplements. Summary of the Invention

[0004] This invention addresses the problem that existing automatic pet feeders cannot automatically prepare nutritional supplements for pets.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic pet feeder, comprising: a one-button brewing device for brewing nutritional supplements; a storage tank disposed below the one-button brewing device for storing and dispensing food; a pet food tray disposed below the one-button brewing device and the storage tank; and a microcontroller connected to the one-button brewing device and the storage tank for storing control programs and controlling the synchronous and coordinated operation of the various devices.

The timer switch and the temperature control switch are connected to the control valve and a microcontroller. The microcontroller controls the timer switch and the temperature control switch to turn on or off at set times. When the heating rod heats the water to a set temperature, the temperature control switch turns on. The timer switch and the temperature control switch are connected in series. The control valve only opens when both the timer switch and the temperature control switch are on. The hose is connected to the needle tube away from the control valve.

[0008] Preferably, the moving device includes: a crank, one end of which is rotatably connected to a side of the water tank; a first motor, which is connected to the microcontroller and whose output shaft is fixedly connected to the crank, driving the crank to rotate; a connecting rod, one end of which is rotatably connected to the other end of the crank; a slider, which is rotatably connected to the other end of the crank; a slide rail, which is fixedly connected to a side of the water tank where the crank is located, the slider being sleeved on the slide rail and slidably connected to the slide rail, and the needle tube being fixedly connected to the slider.

[0009] Preferably, the storage box is provided with a food dispensing door and a food dispensing chute. The food dispensing door is connected to the microcontroller, which controls the opening and closing of the food dispensing door. The food dispensing chute is used to transport food into the pet food tray.

[0010] Preferably, the delivery device includes a nutrient solution nozzle, a water nozzle with a control switch, a first hose, and a second hose. The nutrient solution nozzle is used to transfer the prepared nutrient solution into the pet food dish. One end of the water nozzle is connected to the water tank through the first hose, and the other end is connected to the second hose placed inside the pet food dish to transfer water into the pet food dish.

[0011] Preferably, the pet food tray is provided with a partition inside, which divides the pet food tray into two independent receiving areas. The nutrient nozzle and the food dispensing slide deliver the food to one receiving area, and the second hose is located in the other receiving area.

[0014] Preferably, the nutrient nozzle and the water nozzle are funnel-shaped.

[0015] Preferably, the outer packaging of the capsule is aluminum foil.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The microcontroller pre-stores the control program for controlling the synchronous and coordinated operation of each device, so the microcontroller can control the timer switch to turn on, so that the heating rod starts to heat the water. When the water temperature reaches the set value, the temperature control switch turns on. At this time, the temperature control switch and the timer switch control the valve to open, and then the water is introduced into the syringe through the hose. The first motor drives the crank to rotate, the crank drives the connecting rod to rotate, and the connecting rod drives the slider to move up and down along the slide rail. When the slider moves the syringe down to the set distance, the needle will puncture the upper surface of the capsule and inject warm water into the capsule. After waiting for the preset pause time, the slider continues to move the syringe down to the set distance, puncturing the lower surface of the capsule and transferring the prepared nutrient solution to the nutrient solution nozzle, which then delivers it to the pet food tray.

[0036] Working principle: The microcontroller 4 stores a control program that coordinates the operation of each device. Based on the pre-stored program, the microcontroller 4 controls the operation of each device. First, it controls the storage box 2 to open its door, allowing food to fall into the pet food tray 3 along the food dispensing chute 22. Then, it controls the timer switch 113 to open, causing the heating rod to heat the water. When the water temperature reaches the set value, the temperature control switch 114 opens. At this time, the temperature control switch 114 and the timer switch 113 control the valve 115 to open, and then the water is fed into the syringe 17 through the hose 112. The first motor 132 drives the crank 131 to rotate, and the crank drives the connecting rod 133 to rotate. The connecting rod 133 drives the slider 134 to move up and down along the slide rail 135. When the slider 134 drives the syringe 17 to move down to the set distance, the needle 18 will puncture the upper surface of the capsule 12 and inject warm water into the capsule 12. After waiting for the preset pause time, the slider 134 continues to drive the syringe 17 to move down to the set distance, puncturing the lower surface of the capsule 12 and transferring the prepared nutrient solution to the nutrient solution nozzle 161. The nutrient solution nozzle 161 delivers the solution into the pet food tray 3. When not in use, the timer switch 113 is turned off first, causing the control valve 115 to close. After the water in the water tank cools down, the temperature control switch 114 automatically turns off.

[0037] In summary, this invention can automatically prepare nutrient solutions and add them to pet food, thus effectively solving the problem that existing automatic pet feeders cannot automatically prepare nutrient solutions for pets.
