Description

Technical Field

[0001] The present invention particularly relates to an intelligent rice bucket. Background Art

[0002] Rice buckets are common in ordinary households and are used to store rice. With technological advancements, smart rice buckets have emerged on the market, combining functions such as freshness preservation, automatic metering, and moisture and insect protection, making them a more secure and convenient rice storage product for users.

[0003] In order to reduce the number of times the rice bucket is opened, reduce the possibility of pollution, and accurately control the amount of rice used, a rice discharging device with a metering function is often provided in the smart rice bucket. The traditional rice discharging device includes a horizontally arranged rice discharging channel, with a rice inlet connected to the rice storage chamber provided above one end of the rice discharging channel, and a rice outlet connected to the rice discharging box provided below the other end. The rice discharging channel is provided with a rice pushing screw driven by a motor and pushing the rice from the rice inlet to the rice outlet when rotating. The amount of rice discharged is controlled by the speed and rotation duration of the rice pushing screw. There are many factors that affect the amount of rice discharged, such as whether the amount of rice between adjacent threads of the rice pushing screw is consistent, whether the speed of the rice pushing screw is always consistent, whether there is rice residue at the rice outlet, etc., resulting in limited metering accuracy of this method. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide a smart rice bucket with improved measurement accuracy.

[0005] To achieve the above object, the present invention provides the following technical scheme: comprising a housing, a rice storage chamber and a rice discharging box, wherein the lower portion is provided with a lower rice outlet, the upper portion of the rice discharging box is provided with a rice connecting port, the housing is provided with a box taking port for taking the rice discharging box out of the housing, a metering rice discharging device is provided between the rice storage chamber and the rice discharging box, and the characteristic is that the metering rice discharging device comprises an upper baffle, a lower baffle, a metering slide and a driving mechanism, a metering channel for horizontal movement of the metering slide is provided between the upper baffle and the lower baffle, the metering slide is provided with a vertically connected metering chamber, the upper baffle is located below the lower rice outlet and is provided with a rice inlet communicated with the lower rice outlet, the lower baffle is located above the rice connecting port and is provided with a rice outlet communicated with the rice connecting port, and when the metering slide is driven by the driving mechanism to move, the metering chamber is above the rice inlet UNICOM and below is closed by the lower baffle at a rice inlet position and the rice inlet is closed by the metering slide and below is connected to the rice outlet UNICOM.

[0006] By adopting the above technical solution, the volume of the metering chamber is used as a unit of rice. When the metering slide is located at the rice inlet position, since the bottom of the metering chamber is closed by the lower baffle, the rice in the rice storage chamber falls into the metering chamber from the rice inlet until it is full. Then, the metering slide is driven by the driving mechanism to move. When it reaches the rice outlet position, the rice inlet is closed by the metering slide, and the rice will not continue to fall. The rice in the metering chamber falls through the rice outlet to the rice outlet box outside the metering chamber, thereby completing a single equal amount of rice outlet action. When several units of rice are needed, the metering slide can move back and forth between the rice inlet position and the rice outlet position multiple times. Compared with the traditional metering method, this method has fewer factors that affect the rice outlet amount, is easier to accurately control the rice outlet amount, and improves the metering accuracy. At the same time, it has the advantages of reducing the number of times the rice bucket is opened and reducing the possibility of pollution.

[0010] By adopting the above technical solution, the space under the lower baffle is rationally utilized to accommodate the motor, and the second connecting rod is designed to be above the first connecting rod so that the second connecting rod does not hinder the continuous rotation of the first connecting rod. As a result, the continuous rotation of the motor shaft in one direction can realize multiple round trips of the metering slide, simplifying the circuit control and making the rice feeding action smoother and more efficient.

[0014] By adopting the above technical solution, in order to optimize the cooling effect on rice, on the one hand, the main air duct is fixed on the outer side surface of the rice storage chamber composed of the height direction and the width direction, and the outer side surface composed of the height direction and the length direction with a larger area is reserved as a connecting position, which can effectively increase the circulation area of ​​the cooling airflow. On the other hand, the double air outlet branch ducts and the double air inlet branch ducts are coordinated to allow the cooling airflow to enter from both sides of the bottom of the rice storage chamber, that is, enter the gap at the depth of the rice and flow towards the middle of the depth of the rice. After reaching the middle, it gradually rises and flows out from both sides of the space above the rice, forming a comprehensive cooling airflow circulation, thereby avoiding the cooling airflow not passing through the rice at the deep end, resulting in the rice at the deep end still being damp and stale.

[0020] By adopting the above technical solution, the air flow will be cooled during the flow process and condensed to produce water vapor or water droplets.

In addition, the flow holes of the baffle will not hinder the condensed water from flowing to the condensation channel.

[0024] By adopting the above technical solution, when the remaining rice is large, the ultrasonic sensor can accurately measure the remaining rice and display it on the panel. When the remaining rice is small, the function of the ultrasonic sensor gradually weakens, and the infrared sensor is used to trigger an alarm when the remaining rice is lower than the set amount, accurately prompting the user to refill the rice.

The metering slide 4 is provided with a vertically penetrating metering cavity 44. The upper baffle 41 is located below the lower rice port 22 and is provided with a rice inlet 411 connected to the lower rice port 22. The lower baffle 42 is located above the rice receiving port 31 and is provided with a rice outlet 421 connected to the rice receiving port 31.

Figure 4 As shown) and the rice inlet 411 is closed by the metering slide 4, and the rice outlet position ( Figure 5 As shown), the volume of the metering chamber 44 is used as a unit of rice quantity. When the metering slide 4 is in the rice-in position, since the metering chamber 44 is closed by the lower baffle 42 below, the rice in the rice storage chamber 2 falls into the metering chamber 44 from the rice inlet 411 until it is full. Then, the metering slide 4 is driven by the driving mechanism to move. When it reaches the rice-out position, the rice inlet 411 is closed by the metering slide 4, and the rice does not continue to fall. The rice in the metering chamber 44 falls to the rice outlet box 3 outside the metering chamber 44 through the rice outlet 421, thereby completing a single equal amount of rice-out action. When several units of rice are needed, the metering slide 4 can go back and forth between the rice-in position and the rice-out position multiple times. Compared with the traditional metering method, this method has fewer factors affecting the amount of rice out, is easier to accurately control the amount of rice out, improves the measurement accuracy, and at the same time, has the advantages of reducing the number of times the rice bucket is opened and reducing the possibility of pollution.

The position sensor 431 corresponds to the position of the first connecting rod 452 or the second connecting rod 453 when detecting that the metering slide 4 is in the rice feeding position, and is used to detect whether the first connecting rod 452 or the second connecting rod 453 exists. The position sensor 431 is additionally provided to detect the first connecting rod 452 or the second connecting rod 453 passing each time, so as to control the number of round trips of the metering slide 4 by clicking, and thereby accurately control the total amount of rice output.

[0043] When the metering slide 4 is in the meter-out position, the first connecting rod 452 and the second connecting rod 453 are arranged in a straight line. When it is in the meter-in position, the first connecting rod 452 and the second connecting rod 453 are arranged in a vertical stack. The meter-in position and the meter-out position are opposite to the two extreme positions of the rotation of the first connecting rod 452, making the meter-in and meter-out actions easier to control accurately.

[0044] The metering slide 4 is provided with an extension portion 46 which is in contact with the upper baffle 41 and closes the rice inlet 411 when the metering slide 4 moves from the rice inlet position to the rice outlet position. The second connecting rod 453 is hinged to the bottom of the extension portion 46. The extension portion 46 is added to increase the sliding contact area between the slide and the upper baffle 41, thereby further improving the sliding stability. At the same time, the rice inlet 411 is closed to prevent rice from leaking between the upper baffle 41 and the lower baffle 42.
