The terms "install", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

In one aspect, an embodiment of the present invention provides a grain adding device, as shown in FIG. 1, which includes: a grain box 10, a transmission unit 20, a grain leakage pipe 30, a strainer 40, a first pipe member 50, and a grain collection unit 60. The exhaust fan 70 and the controller 80; the grain box 10 is connected to the feed opening of the grain leak pipe 30 through the transmission unit 20; the air inlet of the grain leak pipe 30 is provided with a filter 40 and communicates with the outside air; The outlet is in communication with the inlet of the grain collection unit 60 through the first pipe 50; the outlet of the grain collection unit 60 is provided with an exhaust fan 70, and the transfer unit 20 is used to transfer the grain in the grain box 10 to the grain drain pipe 30; The controller 80 is electrically connected to the transmission unit 20 and the exhaust fan 70, respectively.

The grain box 10 refers to a box for storing grain. The transfer unit 20 refers to a device for connecting the grain tank 10 and the grain drain pipe 30, and is used to transfer the grain in the grain tank 10 into the grain drain pipe 30. For example, the transmission unit 20 may be a device including a valve 21, or may be a device including a conveyor belt, a motor, and the like. The grain leakage pipe 30 refers to a pipe that can provide an air source and can provide a path from the grain tank 10 to the grain collection unit 60. The strainer 40 refers to a strainer 40 for providing a source of wind power and for preventing the grain from falling out of the device. The first pipe member 50 refers to a pipe connecting the grain drain pipe 30 and the grain collection unit 60. The grain collection unit 60 refers to a device for collecting grains, that is, a target container to which grains are to be added, such as an inner pot of a rice cooker or the like.

Specifically, when it is necessary to add grain, the controller 80 may first control the exhaust fan 70 to start working to ensure that sufficient suction power is provided before the grain falls. When the exhaust fan 70 runs for a certain period of time, a stable and sufficient wind is formed. The controller 80 then controls the transmission unit 20 to send the grain from the grain box 10 to the grain leak pipe 30, and the grain in the grain leak pipe 30 flows with the wind to the entrance of the grain collection unit 60. Under the action of gravity, the grain falls on the Grain collection unit 60. After the grain is added, the controller 80 may also control the transmission unit 20 and the exhaust fan 70 to stop working to complete the automatic grain addition.

It should be noted that the controller 80 can control the amount of grain output from the grain box 10 to the grain collection unit 60 by controlling the operation of the transmission unit 20 to start and stop. There can be various detections of the amount of grain output by the grain box 10 Method to realize. For example, the weight of the remaining grain in the grain box 10 can be measured, and the amount of grain output by the grain box 10 can be measured by measuring the weight change amount of the remaining grain. It is also possible to measure the weight change of the grain collection unit 60 to detect the weight of the grain input to the grain collection unit 60, and to estimate the amount of grain output from the grain bin 10.

The grain adding device provided by the embodiment of the present invention uses the controller 80 to control the exhaust fan 70 and the transmission unit 20 to realize the automatic grain adding, instead of the manual operation in the conventional technology.

In one embodiment, as shown in FIG. 2, the grain tank 10 is located above the grain leak pipe 30, and the transmission unit 20 includes a valve 21; the controller 80 is electrically connected to the valve 21 for controlling the opening or closing of the valve 21, The amount of grain transferred from the grain tank 10 to the grain drain pipe 30 is brought to a target amount.

The upper part refers to the direction that the cereal drain pipe 30 and the cereal box 10 are generally vertically upward when horizontally arranged, so that when the valve 21 is opened, the grain in the cereal box 10 can fall into the cereal drain pipe 30 by gravity. .

Specifically, the controller 80 is electrically connected to the valve 21, and the valve 21 is in a closed state when grain addition is not required. When it is necessary to add grain, the controller 80 controls the valve 21 to open, and the grain in the grain tank 10 falls into the grain leakage pipe 30 along the opening of the valve 21 under the action of gravity, and the grain falling into the grain leakage pipe 30 is in a ventilation. The wind generated by the operation of the machine 70 moves along the first pipe 50 toward the grain collection unit 60. After the grain moves to the entrance of the grain collection unit 60, the grain falls into the grain collection unit 60 to complete the grain addition and transmission.

The controller 60 can control the opening and closing of the valve 21 to control the amount of added grain. For example, the controller 60 stores an opening cross-section of the valve 21, and the timer starts when the controller 60 controls the valve 21 to open. According to the opening time of the valve 21, the amount of grain output by the grain box 10 can be calculated. When the amount of grain output by the grain box 10 reaches the target amount, the controller 60 controls the valve 21 to close, so as to achieve precise control of the amount of grain added.

In one embodiment, as shown in FIG. 2, it further includes an electronic scale 22. The electronic scale 22 is used to collect the weight information of the remaining grain in the grain box 10. The controller 60 is electrically connected to the electronic scale 22 and used to receive the electronic scale. 22 The weight information of the grain remaining in the grain box 10 transmitted.

In order to achieve the precise addition and transmission of grain, the judgment of whether the amount of grain output from the grain box 10 reaches the target amount can also be set by setting up an electronic scale 22, which is used to weigh the current remaining grain in the grain box 10 and give The controller 80 feeds back weight information to determine whether a target amount of grain has been transferred to the grain collection unit 60. The electronic scale 22 may be provided at the bottom of the grain bin 10 or the like. For example, 500 g of rice needs to be added to the grain collection unit 60. The controller 80 first controls the exhaust fan 70 to work for a period of time to form a stable wind, and obtains the weight information of the electronic scale 22 to obtain the initial grain weight in the grain box 10. Then control the transmission unit 20 to work and continuously transmit the grain to the grain collection unit 60. When the controller 80 determines that 500 g of rice has been output from the grain box 10 according to the remaining grain weight in the grain box 10 fed back by the electronic scale 22, it means that To achieve the target amount of grain transmission, the controller 80 may control the transmission unit 20 to stop working, and then control the exhaust fan 70 to stop working to complete the grain addition.

In one embodiment, as shown in FIG. 2, the grain adding device further includes a second pipe piece 90. One end of the second pipe piece 90 passes through the outlet of the grain collection unit 60 and is connected to the grain collection unit 60. The second pipe piece 90 The other end is connected to the exhaust fan 70.

The second pipe 90 is used to provide an air duct between the grain collection unit 60 and the exhaust fan 70. Specifically, one end of the second pipe 90 passes through the outlet of the grain collection unit 60 and is connected to the grain collection unit 60, and the other end is connected to the exhaust fan 70. When the exhaust fan 70 operates, the air leaking from the grain 40 is used to form a leakage from the grain. The wind from the pipe 30 to the first pipe member 50, to the grain collection unit 60, and finally to the second pipe member 90.

In one embodiment, as shown in FIG. 2, a part of the pipes of the first pipe fitting 50 is at the same height as the second pipe fitting 90. To provide a stable grain movement route, a portion of the first pipe member 50 is at the same height as the second pipe member 90.

In one embodiment, as shown in FIG. 2, a dust filter 91 is provided at the exit of the grain collection unit 60.

When adding grain, the grain may be doped with a small amount of dust. Because the dust is very light, when the dust moves with the grain to the entrance of the grain collection unit 60, the grain falls into the grain collection unit 60 with the effect of gravity, and the dust follows the wind. The force flies towards the exhaust fan 70 and is discharged. In order to avoid some light-weight grains also being discharged with the dust, a dust filter 91 is provided at the outlet of the grain collection unit 60. The dust filter 91 can allow small particles of dust to pass through and The grain is intercepted to prevent it from being transmitted to the exhaust fan 70 by the wind. Among them, preferably, one end of the dust filter 91 may be disposed at the upper edge of the entrance of the grain collection unit 60, and the other end of the dust filter 92 may be disposed at the lower edge of the exit of the grain collection unit 60, that is, the dust filter 91 is disposed obliquely at the grain collection unit The top of 60 is used to intercept the grain that is transmitted to the entrance of the grain collection unit 60 with the wind, change the movement route of the grain, make the grain fall into the grain collection unit 60, and prevent the grain from being transmitted to the exhaust fan 70 with the wind .

On the other hand, the embodiment of the present invention also provides a grain adding control method applied to the grain adding device, as shown in FIG. 3, including:

S120: After the exhaust fan 70 is operated for the first preset time, the control transmission unit 20 is controlled to operate, so that the grain in the grain box 10 is transmitted to the grain drain pipe 30;

S140: When the amount of grain output by the grain tank 10 reaches the target amount, the control transmission unit 20 stops working.

The definitions of the terms such as the grain box 10 and the grain leakage pipe 30 are the same as those in the above embodiment, and will not be repeated here. The first preset time refers to the time left for the exhaust fan 70 to form a stable wind first, for example, it may be a time less than 1 minute and may be 10 seconds. This time setting is obtained in advance according to the test and is the same as the first pipe 50 And so on. The target amount refers to the amount of grain to be added to the grain collection unit 60.

Specifically, when a certain amount of grain needs to be added to the grain collection unit 60, after the first preset time of the exhaust fan 70 is operated, it is considered that a stable wind has been formed. At this time, the control transmission unit 20 is operated, and the grain tank 10 The grains in are conveyed into the grain leakage pipe 30 with the transmission unit 20, and the grains falling into the grain leakage pipe 30 are moved by the wind through the first pipe member 50 into the grain collection unit 60. When the amount of grain output by the grain box 10 reaches the target amount, it means that the amount of grain added to the grain collection unit 60 has reached the requirement at this time, the control transmission unit 20 stops working, and stops conveying the grain to the grain collection unit 60, thereby realizing the grain Add and transfer automatically.

In one embodiment, as shown in FIG. 4, after the step of controlling the transmission unit 20 to stop working, the method further includes:

S160: At a second preset time after the transmission unit 20 stops working, the exhaust fan 70 is controlled to stop working.

The second preset time is an amount of time preset according to the test, and may be, for example, a time less than 1 minute. Specifically, in order to prevent grains remaining in the first pipe 50 or the grain leaking pipe 30, after the second preset time after the transmission unit 20 stops working, and then controlling the exhaust fan 70 to stop working, the first pipe 50, All the grains remaining in the grain leakage pipe 30 are output to the grain collection unit 60.

In order to better describe the solution in the embodiment of the present invention, a specific embodiment is listed here, but it should be noted that this embodiment does not limit the protection scope of the solution. For example, if it is necessary to add 500g of rice to the grain collection unit 60, the controller 80 first controls the exhaust fan 70 to start working to ensure that sufficient suction power is provided before the rice falls, and is formed when the exhaust fan 70 runs for the first preset time T Stable and sufficient wind, T can be less than 1 minute, the controller 80 then controls the transmission unit 20 to send the rice into the cereal leakage pipe 30. The advantage of starting the exhaust fan 70 first is to ensure that the rice has sufficient pumping force before the rice falls. Suction is not easy to cause clogging. At the same time, the ash layer after the rice falls will only remain in the first pipe 50, and will not remain outside the air duct system.

Then, after controlling the transmission unit 20 to add the amount of rice required by the user, stop the transmission unit 20 first, wait for the exhaust fan 70 to run for a second preset time T1, and then control the exhaust fan 70 to stop working. T1 can be less than 1 minute. Stopping the transmission unit 20 for a period of time and then stopping the extraction fan 70 to ensure that there is no rice residue in the air duct system.

In one embodiment, as shown in FIG. 4, before the step of controlling the transmission unit 20 to stop working when the amount of grain output by the grain tank 10 reaches the target amount, the method further includes:

S130: Determine whether the amount of grain output by the grain tank 10 reaches the target amount.

In order to ensure that the required amount of grain can be accurately added to the grain collection unit 60, it is necessary to determine whether the amount of grain output by the grain tank 10 has reached the target amount. There can be multiple implementations of the judgment. For example, the remaining grain weight information in the grain box 10 can be obtained through an electronic scale or the like. According to the change of the remaining grain weight information in the grain box 10, the grain amount transmitted by the transmission unit 20 can be obtained. Specifically, if the initial remaining grain amount is M0 and the remaining grain amount at a certain time is M1, when M0-M1 = My, it is considered that the required grain amount has been added to the grain collection unit 60, where My is Target amount.

If the output of the grain from the grain box 10 is achieved by controlling the opening or closing of the valve 21, specifically, it can be timed when the grain box 10 starts to output the grain, and then calculated based on the opening degree of the valve, the flow rate of the grain, and the opening time of the valve 21 The amount of grain output from the grain box 10 is output, and then the obtained grain amount is compared with the target amount to determine whether the grain box 10 has currently output the target amount of grain.

In one embodiment, as shown in FIG. 4, after the exhaust fan 70 is operated for a first preset time, before the step of controlling the operation of the transmission unit 20 further includes:

S110: Control the operation of the exhaust fan 70 according to the received trigger instruction.

The trigger instruction refers to an instruction for notifying the controller 80 to perform grain transmission control. The trigger instruction may be sent by a remote terminal, or may be triggered by a manual trigger on a related key on the controller 80 or the like. For example, it can be a function button on a rice cooker, or it can be an icon button on a mobile terminal App interface.

It should be understood that although the steps in the flowchart of FIG. 3-4 are sequentially displayed according to the directions of the arrows, these steps are not necessarily performed sequentially in the order indicated by the arrows. Unless explicitly stated in this document, the execution of these steps is not strictly limited, and these steps can be performed in other orders.

A power control module 1 configured to control the transmission unit 20 to operate after the exhaust fan 70 runs for a first preset time, so that the grain in the grain box 10 is transmitted to the grain drain pipe 30;

The stop transmission control module 2 is used for controlling the transmission unit 20 to stop working when the amount of grain output by the grain box 10 reaches a target amount.

Specifically, the power control module 1 controls the transmission unit 20 to operate after the exhaust fan 70 runs for the first preset time, so that the transmission unit 20 drives the grain in the grain box 10 to the grain drain pipe 30, and then, when the grain box 10 outputs When the amount of grain reaches the target amount, it is considered that a sufficient amount of grain has been added to the grain collection unit 60 at this time, and the stop transmission control module 2 controls the transmission unit 20 to stop working.
