Referring to fig. 1 and 2, an embodiment of the present utility model provides an automatic feeding system, which includes a storage bin 1, a discharging mechanism, a feeding pipe 4, a discharging mechanism and an air extracting device 8 that are sequentially connected, and further includes a cooking dish 9 located below the discharging mechanism, the air extracting device 8 provides suction force to pump the material in the storage bin 1 to the interior of the discharging mechanism, the discharging mechanism selectively discharges or prevents the material in the storage bin 1 from entering the feeding pipe 4, and the discharging mechanism selectively discharges or prevents the material in the discharging mechanism from entering the cooking dish 9.

The storage bin 1 is used for storing materials such as grains and the like, and realizes the grain storage function of the applied cooking equipment.

When the automatic feeding system is in a feeding state, as shown in fig. 3, the discharging mechanism selects to discharge the materials in the storage bin 1 so that the materials are allowed to enter the feeding pipe 4; the blanking mechanism is selected to discharge the contents of its interior so that the contents are allowed to enter the cooking vessel 9. During feeding, the suction force is provided by the work of the air draft device 8, rice and other materials stored in the storage bin 1 are sequentially subjected to the suction force and pass through the discharging mechanism, the feeding pipe 4 and the discharging mechanism, and finally enter the cooking vessel 9, so that automatic feeding can be realized, manual addition of a user is not needed, and the convenience is improved by releasing both hands.

The embodiment has the advantages of simple structure and wide application range, and can improve the automation degree of cooking equipment such as an electric cooker and the like and improve the use experience of a user. The method solves the problem that in the prior art, when the cooking equipment is used, the step of adding rice and other materials into the cooking vessel still needs manual participation of a user to be completed, so that the degree of automation is low.

The automatic feeding system can be matched with the preset feeding function of the cooking equipment, the user can specify the feeding time, the cooking equipment can automatically feed according to the specified feeding time, and the degree of automation is further improved.

The automatic feeding system may have the following condition, when the height of the partial or whole structure of the feeding pipe 4 is lower than the height of the discharging mechanism, the partial material remains in the feeding pipe 4 under the self gravity when the air exhausting device 8 stops exhausting air, and the problem that the material in the feeding pipe 4 cannot be completely discharged exists.

For the problems described in the previous paragraph, please refer to fig. 1, 2 and 6 in combination, as an alternative embodiment, the discharging mechanism includes a three-way member 3 and a first valve 5 disposed outside the three-way member 3, where the three-way member 3 has three ports, namely, a first port 31, a second port 32 and a third port 33. The first port 31 is communicated with the storage bin 1, the second port 32 is communicated with the feeding pipe 4, and the third port 33 is communicated with the outside. The first valve 5 controls the third port 33 to be opened or closed.

In this way, according to the above structure, the function of evacuating the inside of the feed pipe 4 can be realized. When the feeding pipe 4 is required to be emptied, the air exhausting device 8 keeps the air exhausting work, the first valve 5 selectively opens the third port 33, as shown in fig. 4, so that the third port 33 is communicated with the outside, the internal space of the three-way piece 3 is further communicated with the outside, the outside air is sucked into the three-way piece 3 from the third port 33 to balance the negative pressure in the three-way piece 3, and the suction force of the negative pressure on the materials in the storage bin 1 is relieved. Outside air is sucked into the three-way piece 3 from the third port 33, then enters the feeding pipe 4 through the second port 32, the air flow brings the material in the feeding pipe 4 into the discharging mechanism to discharge the material into the cooking dish 9, and the residual material in the feeding pipe 4 is completely conveyed to the cooking dish 9, so that the emptying function of the feeding pipe 4 is realized.

Optionally, a feed delay condition is set for the automatic feed system, and the feed pipe 4 is emptied when the automatic feed system is in the feed delay condition. As an alternative example, the following is:

In the non-feeding state, as the air draft device 8 does not draft air, negative pressure cannot be generated in the three-way piece 3, and therefore the materials in the storage bin 1 are static;

when the automatic feeding system is in a feeding state, as shown in fig. 3, the air suction device 8 performs air suction, the discharging mechanism is in a state of allowing the materials in the discharging mechanism to enter the cooking dish 9, and the first valve 5 closes the third port 33. The suction device 8 works to provide suction force, and as the first valve 5 closes the third port 33, negative pressure is generated in the three-way piece 3, and the materials in the storage bin 1 sequentially pass through the three-way piece 3, the feed pipe 4 and the discharging mechanism by the suction force and finally enter the cooking vessel 9 to realize the feeding process, and when the feeding reaches the required or required material quantity, the automatic feeding system enters a feeding delay state;

when the automatic feeding system is in a feeding delay state, as shown in fig. 4, the air draft device 8 keeps the air draft and blanking mechanism in a state of allowing the materials in the air draft and blanking mechanism to enter the cooking dish 9, the first valve 5 opens the third port 33, so that the internal space of the three-way piece 3 is communicated with the outside, the outside air is sucked into the three-way piece 3 from the third port 33 to balance the negative pressure in the three-way piece 3, the suction of the negative pressure on the materials in the storage bin 1 is relieved, and the materials in the storage bin 1 stop entering the three-way piece 3. Outside air is sucked into the three-way piece 3 from the third port 33, then enters the feeding pipe 4 through the second port 32, the air flow brings the material in the feeding pipe 4 into the discharging mechanism to discharge the material into the cooking dish 9, and the residual material in the feeding pipe 4 is completely conveyed to the cooking dish 9, so that the emptying function of the feeding pipe 4 is realized. Optionally, a time delay period may be set, and when the air extracting device 8 works to meet the time delay period, the air extracting device 8 stops the air extracting and discharging mechanism to enter a state of preventing the materials in the air extracting and discharging mechanism from entering the cooking dish 9.

As an alternative example, as shown in fig. 6, the first port 31 is located at the top of the tee 3, the second port 32 and the third port 33 are located below the first port 31, and the second port 32 and the third port 33 are located on the same horizontal line. The inner wall of the three-way member 3 may be provided with an inclined surface inclined gradually from top to bottom to the inner direction so as to concentrate the material to the second port 32, so that the material is sucked out through the second port 32.

As an alternative example, as shown in fig. 6, the side of the three-way member 3 near the first valve 5 has a plurality of second through holes, and the third through hole 33 is formed by a plurality of second through holes, and the aperture of the second through holes is smaller than the diameter of the material stored in the storage bin 1, so as to prevent the material in the three-way member 3 from leaking out of the second through holes to the outside. The first valve 5 comprises a first driving structure 51 and a first valve core 52 which are arranged outside the three-way piece 3, the first driving structure 51 is connected with and controls the first valve core 52 to move, and the first valve core 52 is pressed against and sealed or separated from the third port 33.

The second through hole has an aperture of less than 1.5mm, which is smaller than the diameter of most grains.

When the first valve core 52 pushes against the three-way component 3, the first valve core 52 seals the third port 33 completely, and when the third port 33 leaves the third port 33, the third port 33 is exposed, and at this time, the third port 33 is communicated with the outside.

The tee piece 3 can be fixed at the bottom of the storage bin 1 through locking pieces such as screws. When the automatic feeding system is applied in a cooking apparatus, the first valve 5 may be fixed inside the housing of the cooking apparatus.

The first valve 5 may be, but is not limited to, an electrically operated valve, a pneumatic valve, a solenoid valve, etc.

The discharging channel 13 and the corner 133 thereof can realize the function of automatically stopping discharging the material in the storage bin 1 when the automatic feeding system jumps from the feeding state to the feeding delay state. When the movable feeding system jumps into the feeding delay state from the feeding state, the first valve 5 opens the third port 33, so that the internal space of the three-way piece 3 is communicated with the outside, the suction force of the negative pressure on the material in the storage bin 1 is relieved, the material in the storage bin 11 can be prevented from discharging outwards due to the existence of the corner 133, and the material in the storage bin 1 stops entering the three-way piece 3. The material remaining in the part from the corner 133 of the discharge channel 13 to the channel outlet 132 falls into the three-way element 3 under the action of the atmosphere for emptying.
