[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0034] Unless otherwise defined, 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 pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0035] See Figures 1-6 This utility model discloses a spiral rice dispenser, comprising: a box body 10, a storage compartment 20 inside the box body 10, and a first rice outlet 30 at the lower part of the storage compartment 20; a rice dispensing mechanism 40, which is located at the first rice outlet 30, and includes a drive motor 401 and a rice dispensing screw 402, wherein the drive motor 401 is connected to the rice dispensing screw 402 to drive the rice dispensing screw 402 to rotate and dispense rice; and a control module, which includes a detection unit 50 for detecting the rotational speed and / or number of rotations of the drive motor 401.
[0036] This utility model uses a rice-dispensing screw 402 to achieve spiral rice dispensing by rotation, which makes it convenient for users to take rice. Furthermore, the detection unit 50 detects the speed and / or number of rotations of the drive motor 401. By controlling the speed and / or number of rotations of the drive motor 401, users can achieve quantitative rice dispensing with just one operation.
[0037] In this embodiment of the utility model, the rice dispensing mechanism 40 further includes a rice dispensing cylinder 403, which is sleeved on the outside of the rice dispensing screw 402; the detection unit 50 includes a Hall sensor 501 and a magnet 502, which are respectively disposed on the base of the drive motor 401 or the rice dispensing cylinder 403, and the magnet 502 is disposed on the output shaft of the drive motor 401 or the rice dispensing screw 402, and the magnet 502 rotates with the output shaft of the drive motor 401 or the rice dispensing screw 402.
[0038] Specifically, the Hall sensor 501 is fixed relative to the magnet 502. When the output shaft of the drive motor 401 rotates, the magnet 502 rotates along with the output shaft of the drive motor 401 or the feed screw 402. The magnet 502 generates a rotating magnetic field. Each rotation of the magnetic field causes a change in the magnetic field, which in turn causes a change in the output voltage of the Hall sensor 501, thus forming a pulse signal. This pulse signal is then used in conjunction with the control circuit board 160 of the control module described below to measure the rotational speed of the drive motor 401 using frequency measurement and period measurement methods. Frequency measurement refers to calculating the number of pulses per unit time; period measurement refers to measuring the length of one cycle. Thus, through the interaction of the Hall sensor 501 and the magnet 502, the rotational speed and / or number of rotations of the drive motor 401 can be obtained.
[0039] The target rice output can be obtained by measuring the amount of rice produced per revolution of the rice-producing screw 402 and then calculating the number of revolutions of the drive motor 401.
[0040] Alternatively, the target amount of rice can be obtained by measuring the amount of rice dispensed by the rice dispenser screw 402 within a predetermined time and then adjusting the rotational speed of the drive motor 401.
[0041] In this embodiment of the utility model, a rice outlet 30 is provided with a rice outlet end 60 protruding outward; a rice inlet 404 communicating with the first rice outlet 30 is provided on the rice outlet 403, and a rice inlet 405 for sleeved on the outside of the rice outlet end 60 is provided at the rice inlet 404 to prevent rice leakage.
[0042] In this embodiment of the utility model, the rice-proof trough structure 405 includes an annular step 4051 and an annular baffle 4052 connected to each other; the annular step 4051 is used to support the rice-discharging end 60, and the annular baffle 4052 extends from the annular step 4051 toward the rice-discharging end 60 and is sleeved on the outside of the rice-discharging end 60.
[0043] Specifically, the first rice outlet 30 and the rice inlet 404 are coaxially arranged, and the diameter of the rice inlet 404 on the rice dispensing cylinder 403 is smaller than or equal to the diameter of the first rice outlet 30, so as to prevent rice from leaking out of the storage bin 20 and the outside of the rice dispensing structure from the connection position of the first rice outlet 30 and the rice inlet 404.
[0044] Because the annular step 4051 is concave and the annular baffle 4052 is convex, the annular baffle 4052 is higher than the connection between the first rice outlet 30 and the rice inlet 404, further preventing rice from leaking out of the storage bin 20 and the outside of the rice outlet structure from the connection between the first rice outlet 30 and the rice inlet 404.
[0045] In this embodiment of the utility model, the rice dispensing screw 402 includes a rod body and a flexible spiral blade connected to each other. The flexible spiral blade is coiled on the outside of the rod body, and the outer edge of the flexible spiral blade abuts against the inner wall of the rice dispensing cylinder 403.
[0046] Because the outer edge of the flexible spiral blade abuts against the inner wall of the rice dispensing cylinder 403, the rice dispensing screw 402 can push out rice grains during rotation. When a few rice grains get stuck between the flexible spiral blade and the inner wall of the rice dispensing cylinder 403, the flexible spiral blade itself is flexible. Compared with the rigid spiral blade, the rice dispensing screw 402 with the flexible spiral blade can continue to rotate, thereby pushing the rice grains stuck between the flexible spiral blade and the inner wall of the rice dispensing cylinder 403 to the second rice dispensing port 406. This can avoid the phenomenon of rice getting stuck between the rice dispensing screw 402 and the rice dispensing cylinder 403.
[0047] In this embodiment of the invention, the flexible helical blade is a silicone helical blade.
[0048] Specifically, the silicone spiral blade has a Shore hardness of 60 to ensure that rice does not get stuck and to prevent rice from getting trapped inside the rice dispenser 403.
[0049] Specifically, the rod and the flexible helical blade can be integrally formed, or the rod and the flexible helical blade can be separately manufactured and then connected into one unit by bonding, snap-fitting, welding and other connection methods, so as to achieve integral rotation.
[0050] Specifically, in order to enhance strength and ensure transmission stability, the rod can be made of metal materials, such as steel or iron.
[0051] In this embodiment of the utility model, the rice dispensing cylinder 403 and the rice dispensing screw 402 are both arranged horizontally, the drive motor 401 is located behind the rice dispensing cylinder 403 and the rice dispensing screw 402, a second rice dispensing port 406 is provided in front of the rice dispensing cylinder 403 and the rice dispensing screw 402, and the rice inlet 404 is located near the rear of the rice dispensing cylinder 403.
[0052] In this embodiment of the utility model, the storage compartment 20 is disposed in the upper space of the box 10, the rice dispensing compartment 70 is disposed in the lower space of the box 10, the rice dispensing mechanism 40 is disposed in the upper space of the rice dispensing compartment 70, and the second rice dispensing port 406 is disposed near the middle of the rice dispensing compartment 70.
[0053] A rice dispensing drawer 80 is slidably connected in the lower space of the rice dispensing compartment 70, and a rice dispensing opening 90 for taking out and putting in the rice dispensing drawer 80 is provided at the front of the box body 10.
[0054] It is understandable that the top of the storage compartment 20 is provided with a rice inlet, and a first cover plate 100 is movably connected to the rice inlet, and a second cover plate 110 is movably connected to the rice dispensing inlet 90.
[0055] To better arrange the internal space of the housing 10 and improve space utilization, the rice dispensing drive motor 401 is located behind the rice dispensing cylinder 403 and the rice dispensing screw 402. The second rice dispensing port 406 is located near the middle of the rice dispensing compartment 70. The front of the housing 10 is provided with a rice dispensing port 90 for taking out and putting in the rice dispensing drawer 80. Rice can enter the rice dispensing drawer 80 from the second rice dispensing port 406, so that the rice dispensing drawer 80 can receive the falling rice grains more evenly. The rice grains will not accumulate in front of or behind the rice dispensing drawer 80. It can also avoid the rice dispensing drive motor 401 occupying the front space of the rice dispensing compartment 70 and further avoid the rice dispensing drive motor 401 obstructing the user's view. The user can observe the rice dispensing situation of the second rice dispensing port 406 from the rice dispensing port 90.
[0056] In this embodiment of the utility model, the bottom of the rice drawer 80 is provided with a retrieval recess 120, the side wall of the rice dispensing compartment 70 is provided with a slide rail 130 for sliding connection with the rice drawer 80, and a guide slope 140 is provided in front of the slide rail 130.
[0057] The guide ramp 140 is set at an angle of 30°-60°, preferably 45°.
[0058] Users can insert their fingers into the retrieval recess 120 to retrieve or place the rice drawer 80. When retrieving or placing the rice drawer 80, it can slide along the slide rail 130. Furthermore, due to the guiding effect of the guide slope 140 on the retrieval and placement of the drawer, users are prevented from repeatedly aligning with the slide rail 130 or searching for the angle when retrieving or placing the rice drawer 80. This makes it easier for users to remove or place the rice drawer 80 from the slide rail 130 or into the slide rail 130.
[0059] In this embodiment of the utility model, the control module includes an operation panel 150 and a control circuit board 160. The operation panel 150, the control circuit board 160, the Hall sensor 501 and the drive motor 401 communicate with each other. The operation panel is located outside the box 10, the control circuit board 160 is located in the lower space of the box 10, and the control circuit board 160 is located behind the rice discharge bin 70.
[0060] Understandably, during the production of this spiral rice dispenser, the amount of rice dispensed per revolution of the screw 402 or within a predetermined time is determined based on the size of the screw 402 and the specifications of the rice grains. The user inputs the desired amount of rice dispensed from the operation panel 150. The control circuit board 160 calculates the target number of revolutions or the target time required for the drive motor 401 to produce the desired amount of rice, and controls the drive motor 401 to rotate for the target number of revolutions or the target time. After the detection unit 50 detects the target number of revolutions or the target time of the drive motor 401, the screw 402 follows the drive motor 401 to rotate and produce the desired amount of rice grains. The control circuit board 160 then controls the drive motor 401 to stop working, and the user obtains the desired amount of rice.
[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
