Compared with the prior art, the invention has the beneficial effects that: when a user adds feed into the storage cavity, the handle is rotated to the inner limit position, the handle is pulled upwards, the handle assembly is taken down from the upper end of the shell, the reset button is pressed down, the controller controls the electromagnetic valve b and the electromagnetic valve g to be opened, the controller controls the air pump to work, the air pump pumps out air in the vent groove, the piston descends until the piston moves to the bottom in the storage cavity, the reset button is pressed down again, the controller controls the electromagnetic valve b and the electromagnetic valve g to be closed, and the air pump stops working; the user loads feed into the storage chamber and then mounts the lid assembly to the housing.

Or, a pipeline between the electromagnetic valve b and the air pump is connected with an air pressure sensor, when the air pressure sensor detects that the vacuum degree reaches a set value, the rear piston is lowered to the limit position, and the controller controls the air pump to stop working.

After pouring the fodder into the storage cavity, place the lid subassembly in the shell upper end, rotate handle to outside extreme position, make lid subassembly and shell joint.

When a certain storage tank discharges feed into the feeding tray, the controller controls the electromagnetic valve f and the electromagnetic valve c corresponding to the current storage tank to be opened, the air pump works, the air pressure in the air vent groove is increased, the driving piston moves upwards, and meanwhile, the feed pushes the upper piston to move upwards, so that the upper piston moves to the upper limit position.

And simultaneously, the controller controls the electromagnetic valve f and the corresponding electromagnetic valve h to work to inflate the vent pipe, so that the pushing cylinder drives the pushing plate to move forwards, then the controller controls the electromagnetic valve f and the corresponding electromagnetic valve h to close, the electromagnetic valve g and the corresponding electromagnetic valve a to work to exhaust the vent pipe, so that the pushing cylinder drives the pushing plate to move backwards, and the process is repeated, so that the pushing plate reciprocates and pushes the feed into the discharging cavity.

Along with the dropping of fodder, the weight that the electronic scale detected the edible dish seat increases gradually, and when the electronic scale detected the weight of edible dish seat and reached the setting value, the electronic scale sent the signal to the controller, and all solenoid valves of controller control were closed, and the fodder no longer drops in the feed dish.

When the electronic scale detects that the feed in the food tray reaches a set weight, the controller controls the solenoid valve e and the solenoid valve f to be opened, the controller controls the air pump to work for a set time (3-10 s), the pressure in the piston cylinder is increased, the piston rod drives the food tray seat to move towards the front side of the shell, the piston rod extends to the limit position, the food tray seat completely extends to the front side of the shell, the controller controls the solenoid valve e and the solenoid valve f to be closed, the air pump stops working, and at the moment, the pet can eat the feed in the food tray.

When the controller detects that the pet leaves, the controller controls the electromagnetic valve d and the electromagnetic valve g to be opened, the controller controls the air pump to work for a set time (3-10 s), and air in the piston cylinder is pumped out to enable the tray seat to return to the shell; after the tray seat is completely retracted, the controller controls the electromagnetic valve d and the electromagnetic valve g to be closed, and the controller controls the air pump to stop working.

When the radio frequency receiving module receives a signal sent by the radio frequency transmitting module, the controller controls the solenoid valve j and the solenoid valve f to be opened to inflate the water storage tank, so that water in the water storage tank enters the drinking trough, and after 15-20 days, the solenoid valve j and the solenoid valve f are closed, so that water does not enter the drinking trough any more, and a pet can drink the water conveniently.

When the pet leaves, the radio frequency receiving module cannot receive a signal sent by the radio frequency transmitting module, the controller controls the solenoid valve i and the solenoid valve g to be opened to pump air in the water storage tank, so that water in the drinking trough enters the water storage tank, after 15-20, the solenoid valve i and the solenoid valve g are closed, and the water in the drinking trough flows back into the water storage tank after being filtered.

The two material storage tanks are arranged for storing different types of feed, so that the feed with different tastes or different nutritional ingredients can be provided for pets.

The storage intracavity is used for promoting the fodder through setting up the piston and is in storage chamber upper portion, and the cooperation scraping wings makes the fodder discharge from storage chamber top, has avoided the fodder of large granule irregular shape to produce the problem of card material.

The linkage belts arranged on the two sides of the piston rotate synchronously, so that the long-strip-shaped piston cannot incline in the movement process.

The cover assembly and the shell are relatively fixed by rotating the handle to the outer limit position, and meanwhile, the wireless camera can shoot the state of a pet; rotate the handle to inboard extreme position, make lid subassembly can separate with the shell, the wireless camera is located the upper cover body upper end simultaneously, removes the in-process at the lid subassembly, and the wireless camera can not suffer to collide with.

The second one-way valve is designed to be in a mode that the water outlet faces upwards, so that the upper end of the water outlet of the valve plate is blocked by the water pumping valve plate under the action of self gravity, and when the air pump inflates the water storage tank, the second one-way valve prevents water in the water storage tank from flowing into the drinking trough from bottom to top through the filter box to cause upward overflow of dirt in the filter box.
