[0046] like Figures 1 to 6 As shown, an embodiment of the present invention provides a quantitative rice dispensing mechanism, including an upper cover 100 , a control box 200 , a sealing member 500 , a mounting seat 600 , a reset structure 700 and an operating member 800 .

[0047] Among them, such as Figure 3 As shown, the control box 200 is provided with an intercepting groove 210 for holding rice grains, and one side of the open end of the intercepting groove 210 is closed by an intercepting wall 220.

[0048] The control box 200 can rotate along its axial direction, and has a first position for outputting rice and a second position.

[0049] like Figure 4 As shown, when the control box 200 rotates to the first position, the intercepting wall 220 is in a low position, and part of the rice grains in the intercepting groove are intercepted by the intercepting wall and retained in the intercepting groove, and part of the rice grains in the intercepting groove 210 can be discharged.

[0050] like Figure 5 As shown, when the control box 200 rotates to the second position, the intercepting wall 220 is in a high position, and all the rice grains in the intercepting groove 210 can be discharged.

[0051] It should be understood that the direction in which the control box 200 rotates to the first position is opposite to the direction in which it rotates to the second position for ease of operation. Specifically, the control box 200 is preferably set to rotate 90 degrees counterclockwise to reach the first position, and rotate 180 degrees clockwise from the first position to reach the second position.

[0052] Of course, the control box 200 can also be set to rotate 90 degrees in a clockwise direction to reach the first position, and rotate 180 degrees in a counterclockwise direction from the first position to reach the second position, which is selected according to design requirements.

[0053] That is, the rice output of two specifications can be controlled by cooperating with the intercepting groove 210 and the intercepting wall 220, which is easy to operate. The overall structure of the rice output mechanism is simple and reasonable, and is easy to disassemble and clean, which can greatly improve the user experience.

[0054] In one embodiment, if Figure 3 As shown, the upper cover 100 is provided with a groove 110 with an opening facing downward, and the control box 200 is disposed at the groove 110 and forms a quantitative bin 300 for accommodating rice grains together with the groove 110 .

[0055] like Figure 4 As shown, when the control box 200 rotates to the first position, the intercepting groove 210 can form a first outlet 310 connected to the outside with the groove 110, and the rice grains in the quantitative bin 300 can be discharged from the first outlet 310, and the intercepting groove 210 can intercept part of the rice grains.

[0056] like Figure 5 As shown, when the control box 200 rotates to the second position, the intercepting groove 210 can form a second outlet 320 connected to the outside with the groove 110, and the rice grains in the quantitative bin 300 can be completely discharged from the second outlet 320.

[0057] It should be understood that the amount of rice grains intercepted by the intercepting groove 210 is set according to actual design requirements. In this embodiment, the intercepting groove 210 is preferably set to intercept 75 grams. For example, the quantitative bin 300 contains 150 grams of rice grains. When the control box 200 is rotated to the first position, the first outlet 310 can discharge 75 grams of rice grains; and when the control box 200 is rotated to the second position, all 150 grams of rice grains in the quantitative bin 300 can be discharged, so that users can make choices, which is highly adaptable and convenient.

[0058] In one embodiment, if Figures 3 to 5 As shown, in order to achieve that when the control box 200 is in the first position, the intercepting groove 210 can intercept part of the rice grains, and when it is in the second position, the quantitative bin 300 can completely discharge the rice grains, specifically, the control box 200 includes an intercepting wall 220 and an oblique straight wall 230, wherein the intercepting wall 220 extends upward and the oblique straight wall 230 is inclined downward, and the lower end of the intercepting wall 220 is connected to the lower end of the oblique straight wall 230 to form the intercepting groove 210.

[0059] Specifically, such as Figure 4 As shown, when the control box 200 is rotated to the first position, some rice grains can be intercepted by the intercepting wall 220. More specifically, the intercepting wall 220 is curved, and the inner arc surface of the intercepting wall 220 faces the oblique straight wall 230, that is, some rice grains are intercepted by the curved intercepting wall 220.

[0060] Specifically, such as Figure 5 As shown, when the control box 200 rotates to the second position, the rice grains in the quantitative bin 300 are not blocked by the intercepting wall 220 and can therefore all flow out.

[0061] In one embodiment, the groove 110 is provided with a rice inlet 111 connected to the quantitative bin 300. When the control box 200 is in the initial state, the rice inlet 111 can correspond to the intercepting groove 210, and the rice inlet 111 is engaged with the rice storage bin (not shown) on the rice bucket. The rice grains in the rice storage bin fill the quantitative bin 300 through the rice inlet 111 for subsequent use.

[0062] Further, such as Figures 3 to 5 As shown, the control box 200 also includes a blocking wall 240, wherein the blocking wall 240 extends downward, and the upper end of the blocking wall 240 is connected to the upper end of the oblique straight wall 230. It should be understood that when the control box 200 is in the first position, the blocking wall 240 corresponds to the rice inlet 111; when the control box 200 is in the second position, the intercepting wall 220 corresponds to the rice inlet 111, that is, the intercepting wall 220 and the blocking wall 240 can play a blocking role to prevent a large amount of rice grains in the rice storage bin from flowing into the quantitative bin 300, affecting the accuracy of the rice output. It should be noted that the blocking wall 240 is curved.

[0063] In one embodiment, seals 500 are provided on both sides of the control box 200, and a gap 400 is formed between the intercepting wall 220 and the blocking wall 230 and the groove 110. The two seals 500 can respectively contact the intercepting wall 220 and the blocking wall 230 to close the gap 400.

[0064] Further, such as Figure 4 As shown, when the control box 200 rotates to the first position, the intercepting wall 220 is disconnected from the corresponding sealing member 500, and the end of the intercepting wall 220 away from the oblique wall 230 forms a first outlet 310 with the corresponding sealing member 500, through which part of the rice grains can be intercepted; further, as shown Figure 5 As shown, when the control box 200 rotates to the second position, the end of the inclined straight wall 230 away from the intercepting wall 220 forms a second outlet 320 with the adjacent seal 500, that is, the problem of stuck rice and rice grain residue in the quantitative bin 300 can be avoided through the cooperation of the gap 400 and the seal 500.

[0065] In one embodiment, if Figures 3 to 5 As shown, the seal 500 is tilted toward the control box 200, so that the contact between the intercepting wall 220 and the blocking wall 240 and the corresponding seal 500 is more stable and smooth, and has a longer service life. The lower end of the seal 500 is bent toward the end away from the control box 200, which can improve the stability of the structure at this location. The seal 500 is preferably a soft rubber seal 500.

[0066] In one embodiment, if Figures 3 to 5As shown, the upper cover 100 is clamped on the mounting seat 600 to limit the control box 200. It should be noted that the seal 500 is clamped on the mounting seat 600, and the upper cover 100 is abutted against the clamping end of the seal 500 to compress the seal 500 and ensure the stability of the seal 500.

[0067] Further, if Figure 1 As shown, both ends of the control box 200 are provided with connecting parts 250 extending axially outward, and the mounting seat 600 is rotatably connected to the connecting parts 250 to ensure that the control box 200 can rotate stably. It should be noted that the operating member 800 is connected to one of the connecting parts 250 to operate the control box 200 to rotate.

[0068] Further, if Figure 1 、 2 As shown in FIG6 , the reset structure 700 is provided corresponding to the connecting portion 250 , and one reset structure 700 can drive the control box 200 rotated to the first position to reset, and the other reset structure 700 can drive the control box 200 rotated to the second position to reset, so as to facilitate subsequent operations.

[0069] In certain specific embodiments, such as Figure 1 As shown, the reset structure 700 includes a rotating seat 710 and a reset spring 720, wherein the rotating seat 710 is sleeved on the connecting portion 250 and is rotatably connected to the connecting portion 250, the mounting seat 600 is rotatably connected to the rotating seat 710 and the connecting portion 250, and the reset spring 720 connects the mounting seat 600 and the rotating seat 710. Specifically, the reset spring 720 is arranged at an angle, and a connecting arm connected to the upper end of the reset spring 720 is provided on the rotating seat 710, and the lower end of the reset spring 720 is connected to the mounting seat 600, that is, the reset spring 720 is used to drive the rotating seat 710 to rotate to drive the control box 200 to achieve reset, and the structure is simple and stable.

[0070] Furthermore, an arc-shaped protrusion 711 is provided on one of the rotating seat 710 and the connecting part 250, and an arc-shaped groove 251 cooperating with the arc-shaped protrusion 711 is provided on the other of the rotating seat 710 and the connecting part 250. Specifically, the arc-shaped protrusion 711 is preferably arranged inside the rotating seat 710, and the arc-shaped groove 251 is opened on the outside of the connecting part 250, that is, the connecting part 250 can drive the rotating seat 710 to rotate through the arc-shaped protrusion 711.

[0071] Furthermore, the arc-shaped protrusion 711 and the arc-shaped groove 251 form a movable space (not shown in the figure), through which when one of the connecting parts 250 drives the corresponding rotating seat 710 to rotate, the other connecting part 250 cannot drive the corresponding rotating seat 710 to rotate, thereby preventing the two reset structures 700 from interfering with each other and affecting use.

[0072] In order to make the control box 200 accurately reach the first position after rotating 90 degrees in the counterclockwise direction, and accurately reach the second position after rotating 90 degrees in the clockwise direction, for this purpose, as shown in FIG. Figure 1 As shown, an arc-shaped limit block 712 is provided on the outer side of the rotating seat 710, and both ends of the arc-shaped limit block 712 can abut against the mounting seat 600. After the control box 200 rotates 90 degrees, the arc-shaped limit block 712 can abut against the mounting seat 600, thereby limiting the position and ensuring the accuracy of the rotation position of the control box 200.

[0073] In order to improve the convenience of operation, an operating member 800 connected to the control box 200 is also installed on the rice discharging mechanism. When the operating member 800 is subjected to external force, it can drive the control box 200 to rotate. More specifically, the operating member 800 is a knob.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
