[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0042] like Figure 1-4 As shown, a multi-rice box feeding device comprises a rice box 1, a rice outlet cover 2, a metering impeller 3, a collecting funnel 4 and a pot 5 which are coaxially arranged in sequence;

[0043] The rice box 1 at least comprises a plurality of rice box bodies 11;

[0044] The rice discharging upper cover 2 comprises an upper cover body 21, an upper cover outer gear 22 arranged on the outer ring of the upper cover body 21, an upper cover rice inlet 23 arranged on the upper cover body 21, an upper cover rice discharging structure 24 arranged on the upper cover body 21, and an upper cover driving mechanism 25 for driving the upper cover body 21 to rotate, and the upper cover outer gear 22 is connected to the upper cover driving mechanism 25;

[0045] The quantitative impeller 3 includes an impeller body 31, a quantitative grid 32 arranged on the impeller body 31, an impeller outer gear 33 arranged on the outer ring of the impeller body 31, and an impeller driving mechanism 34 driving the impeller body 31 to rotate, and the impeller outer gear 33 is connected to the impeller driving mechanism 34.

[0046] like Figure 5 As shown, the rice box 1 is used to hold grains, ensuring that the grains inside it can smoothly pass through the rice outlet cover 2 and the metering impeller 3 into the cooker 5, and includes a plurality of rice box bodies 11 and a rice box shaft 12, wherein the plurality of rice box bodies 11 are arranged around the rice box shaft 12, and a rice box outlet 13 is provided at the bottom of the rice box body 11, ensuring that the grains in the rice box 1 can be smoothly discharged through the rice box outlet 13.

[0047] like Figure 3 and 6As shown, the rice discharging cover 2 is used for discharging rice, and includes a cover body 21, an upper cover outer gear 22 arranged on the outer ring of the upper cover body 21, an upper cover rice inlet 23 arranged on the upper cover body 21, an upper cover rice discharging structure 24 arranged on the upper cover body 21, and an upper cover driving mechanism 25 for driving the upper cover body 21 to rotate. The upper cover body 21 is an annular structure. In order to realize the coaxial arrangement of the rice discharging cover 2 and the rice box 1, an upper cover mounting column 26 is provided at the center of the upper cover body 21, and the upper cover mounting column sleeve 26 is arranged on the rice box shaft 12. The upper cover outer gear 22 is arranged on the outer ring of the upper cover body 21, and is connected to the upper cover driving mechanism 25 to ensure that the upper cover driving mechanism 25 can drive the upper cover body 21 to rotate.

[0048] Specifically, the upper cover driving mechanism 25 includes an upper cover motor 251 and an upper cover gear 252 connected to the upper cover motor 251. The upper cover gear 252 is meshed with the upper cover outer gear 22. Therefore, when the upper cover motor 251 is working, it drives the upper cover gear 252 to rotate, and the upper cover gear 252 drives the upper cover outer gear 22 to rotate, thereby driving the rice outlet upper cover 2 to rotate, thereby realizing the selection of grain in different rice box bodies 11 in the rice box 1.

[0049] The upper cover rice inlet 23 is provided on the upper cover body 21, which is a through hole provided on the upper cover body 21, so that the grain in the rice box body 11 can be discharged through the rice box rice outlet 13 and the upper cover rice inlet 23. The upper cover rice outlet structure 24 is located at the bottom of the upper cover body 21, which is an arc structure on the upper cover body 21 extending downward to form a notch 27 on one side thereof, so that the rice in the rice box passes through the rice box rice outlet 13, the upper cover rice inlet 23 and the notch 27 into the aggregate hopper, without the need to specially set a grain slideway, and the structure is simple.

[0050] In order to better measure the amount of rice, the grain needs to be temporarily sealed in the quantitative grid. Therefore, in this embodiment, the rice inlet 23 of the upper cover and the notch 27 are staggered with each other on the axial projection surface of the rice outlet upper cover 2.

[0051] In order to accurately know the rotation angle of the upper cover body, the rice outlet upper cover also includes an upper cover sensor 28 for sensing the rotation angle of the upper cover body 21 , and the upper cover sensor 28 is arranged on the outer side of the upper cover outer gear 22 .

[0052] like Figure 4As shown, the metering impeller 3 is used to control the amount of rice discharged, and includes an impeller body 31, a metering grid 32 arranged on the impeller body 31, an impeller outer gear 33 arranged on the outer ring of the impeller body 31, and an impeller driving mechanism 34 for driving the impeller body 31 to rotate. The impeller body 31 is a rotating body structure, which is coaxially arranged with the rice discharge cover 2, and can slide in the cavity surrounded by the rice discharge cover and the upper surface of the aggregate hopper to achieve grain metering.

[0053] An impeller mounting column 35 is provided on the impeller body, and the impeller mounting column 35 is sleeved on the upper cover rice outlet structure 24. The quantitative grid 32 is provided on the impeller body 31, and the interior of the impeller body 31 is divided into a plurality of spaces by a partition plate to form a plurality of quantitative grids. An impeller rice outlet 36 is provided on the side of the quantitative grid 32 facing the central axis of the impeller body 31. After assembly, the outer wall of the upper cover rice outlet structure 24 abuts against at least one of the impeller rice outlets 36, that is, when the upper cover rice outlet structure 24 blocks at least one of the impeller rice outlets 36, the grain inside the quantitative grid 32 cannot fall into the aggregate funnel. When the notch 27 corresponds to the position of the impeller rice outlet 36, the grain inside the quantitative grid falls into the aggregate funnel 4.

[0054] In order to be able to measure the volume of falling grain, the chord length of the arc structure where the upper cover rice outlet structure 24 is located is greater than the width of the impeller rice outlet, ensuring that the quantitative grid blocked by the upper cover rice outlet structure 24 can be filled with grain for measurement, thereby achieving quantitative delivery of grain.

[0055] The impeller outer gear 33 is arranged on the outer ring of the impeller body 31, and is connected to the impeller driving mechanism 34, so that the impeller driving mechanism 34 can drive the impeller body 31 to rotate. Specifically, the impeller driving mechanism 34 includes an impeller motor 341 and an impeller gear 342 connected to the impeller motor 341. The impeller gear 342 and the impeller outer gear 33 are meshed with each other. Therefore, when the impeller motor 341 drives the impeller gear 342 to rotate, the impeller outer gear 33 is driven to rotate, thereby realizing the rotation of the impeller body 31.

[0056] Correspondingly, in order to measure the amount of grain more accurately, the metering impeller 3 also includes an impeller sensor 37 for sensing the rotation angle of the impeller body 31 , and the impeller sensor 37 is arranged on the outside of the impeller outer gear 33 .

[0057] The collecting funnel 4 is used to collect the grains dropped from the metering impeller 3 so that the grains can smoothly enter the interior of the cookware, and the inner wall of the collecting funnel 4 abuts against the bottom of the partition plate to ensure that the metering grid 32 can form a closed space, thereby ensuring the smooth progress of the grain metering process.

[0058] The pot 5 is used for cooking grains and is located below the collecting hopper 4 .

[0059] like Figure 2 and 7 As shown, the multi-box feeding device provided by the present invention, during the working process, firstly, the required grains are placed inside the rice box body 11, and then the upper cover driving mechanism 25 drives the rice outlet upper cover 2 to rotate, so that the position of the upper cover rice inlet 23 corresponds to the rice box outlet 13 of the corresponding rice box body 11, and the grains fall into the quantitative grid just below the rice box body 11. At this time, because the upper cover rice outlet structure 24 blocks the impeller rice outlet 36 of the quantitative grid 32, the grains will not fall. When the quantitative grid 32 is filled with grains, the impeller driving mechanism 34 drives the The impeller body 31 rotates a quantitative grid until a preset number of quantitative grids 32 are filled, and a corresponding amount of grain can be obtained. When the grain in the quantitative grid 32 needs to be put down, the impeller body 31 only needs to be rotated so that the impeller rice outlet 36 corresponds to the gap 27. Here, since the number of the quantitative grids 32 is set according to actual needs, when the required amount of grain is large, grain will fall from the rice box body 11 into the quantitative grid on one side, and the quantitative grid 32 on the other side will correspond to the gap, and the grain will naturally fall into the aggregate funnel.

[0060] After measuring one type of grain, to measure another type of grain, it is only necessary to drive the upper cover body 21 to rotate through the upper cover driving mechanism 25 so that the upper cover rice inlet 23 corresponds to the rice box outlet 13 of the other rice box body 11, and repeat the above process.

[0061] The multi-rice box feeding device provided by the present invention is provided with a plurality of rice box bodies 11, which realizes the mixing of various grains and meets people's needs for steaming different grains. Through the setting of the quantitative impeller 3, accurate measurement of the quantities of different grains is achieved, which can be achieved by installing only two driving mechanisms. The volume of the device is effectively controlled, the production cost is low, and it is conducive to the promotion and market application of the product.

[0062] Correspondingly, such as Figure 8 As shown, the present invention also provides a feeding method based on the above-mentioned multi-box feeding device, comprising the following steps:

[0063] S1, adding food into the corresponding rice box body 11 as needed;

[0064] S2, the upper cover driving mechanism 25 drives the upper cover body 21 to rotate, so that the upper cover rice inlet 23 corresponds to the rice box rice outlet 13, and the grain falls into the quantitative grid just below the upper cover rice inlet 23;

[0065] S3, after the quantitative grid in step S2 is filled, the impeller driving mechanism 34 drives the impeller body 31 to rotate, so that the next quantitative grid 32 is located below the rice inlet 23 of the upper cover, and the grain falls into the quantitative grid 32. As the quantitative grid 32 rotates, the grain slides from the rice outlet mechanism into the cooker, and this operation is repeated until the grain of the preset number of quantitative grids slides into the cooker;

[0066] S4, the upper cover driving mechanism 25 drives the upper cover body 21 to rotate, so that the upper cover rice inlet 23 corresponds to the next rice box rice outlet 13, and the grain falls into the quantitative grid 32 just below the upper cover rice inlet 23;

[0067] Repeat steps S3 and S4 until all the grains are measured.

[0068] Preferably, in order to more accurately control the rotation angle of the upper cover body 21 and the impeller body 31, so as to accurately measure the amount of falling grain, in step S2, the rotation angle of the upper cover body 21 is sensed by the upper cover sensor 28, and in step S3, the rotation angle of the impeller body 31 is sensed by the impeller sensor 37.

[0069] The following is an example of the quantitative impeller metering process. Figure 8 As shown: the grain in the rice box body 11 falls into the corresponding quantitative grid a through the rice box rice outlet 13 and the upper cover rice inlet 23, and the quantitative grid a is filled (i.e., state A in the figure), and the impeller driving mechanism 34 drives the impeller body 31 to rotate a certain angle, so that the grain falls into the quantitative grid b, and the quantitative grid b is filled (i.e., state B in the figure), and the impeller driving mechanism 34 drives the impeller body 31 to rotate a certain angle again, at which time the position of the impeller rice outlet 36 of the quantitative grid a reaches the notch 27, and the grain is released (i.e., states C, D, and E in the figure), until the grain in the quantitative grid a is emptied (i.e., state F in the figure), thus, a quantitative grid volume of grain is released into the cooker.

[0070] In this embodiment, the internal volume of all the quantitative grids is V. By releasing the grains in n quantitative grids, a volume of nV of grains can be obtained, that is, the preset grain volume Y=nV, wherein n represents the number of quantitative grids, and V represents the volume of a single quantitative grid.

[0071] Assume that the types of food are i, n1 is the number of quantitative grids for the first type of food, n2 is the number of quantitative grids for the second type of food, and n iis the number of quantitative grids for holding the i-th type of grain, and the volume of the grain in the pot can be obtained as Y'=n1V+n2V+…+n i V;

[0072] where i, n, n1 n2…n i are all integers and are greater than or equal to 1, and the n1 n2…n i They can be equal or unequal.

[0073] The feeding method provided by the present invention can automatically measure the amount of rice, and the user can select different quantities of grain combinations according to the needs, thereby meeting the needs of the user, and the operation is automated, convenient and quick.

[0074] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
