[0026] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:
[0027] As Figures 1 to 9 shown, an automatic opening and closing structure of a rice bucket cover includes a cover main body 1. A rice-taking port 2 and a placement cavity 3 with an outward opening are provided on the cover main body 1. A rice cup 4 is placed in the placement cavity 3. A movable cover 5 is also hinged on the cover main body 1. The movable cover 5 rotates to open and expose the rice-taking port 2, and rotates to close and cover the rice-taking port 2. An automatic opening and closing assembly 6 is provided on the cover main body 1. When the rice cup 4 enters / leaves the placement cavity 3, the automatic opening and closing assembly 6 is triggered. The automatic opening and closing assembly 6 is triggered to drive the movable cover 5 to rotate and open as the rice cup 4 is taken out from the placement cavity 3, and the automatic opening and closing assembly 6 is triggered to drive the movable cover 5 to rotate and close as the rice cup 4 is placed into the placement cavity 3.
[0028] In the automatic opening and closing structure of this case, a placement cavity 3 with an outward opening is provided on the cover main body 1. In this way, the rice cup 4 can be placed in the placement cavity 3 when not taking rice, and when the user needs to take rice, the rice cup 4 can be conveniently taken out directly from the placement cavity 3 without rummaging through the rice grains in the rice bucket to find the rice cup 4. This can effectively improve the convenience of the user's rice-taking process. In addition, the automatic opening and closing structure of this case also has an automatic opening and closing assembly 6 that drives the movable cover 5 to act, and this automatic opening and closing assembly 6 can be linked with the rice cup 4, thereby achieving the effect of automatically opening and closing the movable cover 5. When the user needs to take rice, just take out the rice cup 4 from the placement cavity 3, and the automatic opening and closing assembly 6 will drive the movable cover 5 to open, and the user can use the rice cup 4 to take rice through the rice-taking port 2; when the user finishes taking rice, just put the rice cup 4 back into the placement cavity 3, and the automatic opening and closing assembly 6 will drive the movable cover 5 to close. In this way, the opening and closing logic of the movable cover 5 is synchronized with the usage logic of the rice cup 4. The user does not need to unlock the movable cover 5 separately when taking rice, and the movable cover 5 can be ensured to be closed when not taking rice. Thus, through the automatic opening and closing structure of the rice bucket cover in this case, the steps of the user taking rice can be greatly simplified, the convenience of the user using the rice bucket can be improved, and the competitiveness of the product can be significantly enhanced.
[0029] Preferably, the automatic opening and closing assembly 6 is a non-electric pure mechanical assembly.
[0030] As Figures 1 to 7As shown, preferably, the automatic opening and closing component 6 includes a torsion spring 61 sleeved on the hinge shaft of the movable cover 5. One end of the torsion spring 61 abuts against the movable cover 5, and the other end abuts against the cover main body 1 to continuously apply a force to drive the movable cover 5 to rotate and open. An extension rod 62 that rotates synchronously is fixed on the movable cover 5. A hollow groove 63 is provided on the wall surface of the placement cavity 3. When the extension rod 62 rotates, it can pass through the hollow groove 63 and insert / withdraw from the placement cavity 3. When the extension rod 62 inserts into the placement cavity 3, the movable cover 5 is correspondingly in the open state. After the extension rod 62 withdraws from the placement cavity 3, the movable cover 5 is correspondingly in the closed state.
[0031] As described above, in the natural state, the movable cover 5 will rotate in the opening direction under the drive of the torsion spring 61. Correspondingly, the extension rod 62 will also pass through the hollow groove 63 and insert into the placement cavity 3. When the rice cup 4 is placed in the placement cavity 3, the extension rod 62 will be displaced by the rice cup 4 and withdraw from the placement cavity 3. Subsequently, the movable cover 5 can also overcome the elastic force of the torsion spring 61 and rotate synchronously with the extension rod 62 to close. When the user takes out the rice cup 4 to get rice, since the obstacle for the extension rod 62 to insert into the placement cavity 3 has been eliminated, the movable cover 5 can rotate and open under the drive of the torsion spring 61, and the extension rod 62 will also pass through the hollow groove 63 again and insert into the placement cavity 3. In this way, through the linkage of the torsion spring 61, the extension rod 62, the hollow groove 63 and the rice cup 4, the movable cover 5 can be automatically opened when the user gets rice, and automatically closed after getting rice, and there is no need for the user to perform an additional unlocking operation, thus greatly facilitating and simplifying the process of the user getting rice.
[0032] As Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, preferably, the end face of the extension rod 62 that can insert / withdraw from the placement cavity 3 is a smooth curved surface. In this way, the smoothness of the contact surface when the extension rod 62 contacts the rice cup 4 can be ensured, and the process of the rice cup 4 entering and exiting the placement cavity 3 can be made smoother.
[0033] As Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, preferably, the hinge shaft of the movable cover 5 is parallel to the bottom surface of the placement cavity 3. The distance from the end of the extension rod 62 that can insert / withdraw from the placement cavity 3 to the hinge shaft of the movable cover 5 is A, and the distance from the bottom surface of the placement cavity 3 to the hinge shaft of the movable cover 5 is B, and A < B.
[0034] As described above, in the opening and closing structure of this case, the distance A from the end of the extension rod 62 to the hinge axis of the movable cover 5 is less than the distance B from the bottom surface of the placement cavity 3 to the hinge axis of the movable cover 5. In this way, when the rice cup 4 is placed in place, the end of the extension rod 62 will press against the side surface of the rice cup 4. In this way, a certain extrusion force can be applied to the rice cup 4 through the extension rod 62 by means of the elastic force of the torsion spring 61, so that the rice cup 4 can be better fixed in the placement cavity 3 in the natural state. At the same time, it can also prevent the extension rod 62 from pressing against the bottom edge of the rice cup 4 after the rice cup 4 is placed in place, and forming a force that pushes the rice cup 4 out of the placement cavity 3.
[0035] As Figures 2 to 7 shown, preferably, a limit baffle 7 extending backward and downward is provided on the cover body 1, and the limit baffle 7 is used to prevent the movable cover 5 from continuing to rotate in the opening direction after the movable cover 5 is opened to the maximum amplitude, so as to limit the maximum opening amplitude of the movable cover 5.
[0036] As described above, by providing the limit baffle 7, the maximum opening amplitude of the movable cover 5 can be effectively controlled, and it is avoided that too many rice grains in the rice bucket are exposed to the external environment through the rice taking port 2 due to the too large opening amplitude of the movable cover 5, so that the probability of the rice grains being polluted by the external environment can be reduced.
[0037] As Figures 2 to 7 shown, preferably, the left, right, and upper edges of the limit baffle 7 extend to the corresponding side wall surfaces of the cover body 1, the lower edge of the limit baffle 7 is lower than the lowest point of the movable cover 5, and a rice dropping port 8 for the rice grains to fall below the rice taking port 2 is formed between the lower edge of the limit baffle 7 and the lower edge of the cover body 1.
[0038] As described above, by extending the edges of the limit baffle 7 to the left, right, and upper side wall surfaces of the cover body 1, and the lower edge of the limit baffle 7 is lower than the lowest point of the movable cover 5, the rice grains behind the movable cover 5 will be blocked by the limit baffle 7. In this way, it can be avoided that the rice grains are stacked within the rotation range of the movable cover 5 and then hinder the rotation of the movable cover 5, affecting the opening and closing of the movable cover 5. At the same time, the rice grains need to fall through the rice dropping port 8 to below the movable cover 5, so that these rice grains can just be exposed under the rice taking port 2 when the movable cover 5 is opened, thus facilitating the user to take.
[0039] As Figures 3 to 7 shown, preferably, the area of the movable cover 5 is larger than the area of the rice taking port 2, and a sealing ring 9 is provided on the edge of the movable cover 5, and the sealing ring 9 surrounds the rice taking port 2. In this way, when the movable cover 5 is closed, the rice taking port 2 can be further sealed through the sealing ring 9, ensuring that external moisture and foreign objects cannot enter the rice bucket through the rice taking port 2, so as to ensure that the rice grains are well preserved.
[0040] As Figures 1 to 7As shown, preferably, a convex portion 51 for filling the rice taking port 2 is provided on the movable cover 5, and the surface of the convex portion 51 is flush with the surface of the cover main body 1. In this way, by further providing the convex portion 51 on the movable cover 5 to fill the rice taking port 2, it can ensure that the rice dropping port 8 is better closed.
[0041] As Figures 1 to 7 shown, preferably, a bracket member 11 is fixed to the back of the cover main body 1, the placement cavity 3 is provided on the bracket member 11, and the movable cover 5 is hinged to the bracket member 11. In this way, by hinging the movable cover 5 to the bracket member 11 and providing the placement cavity 3 on the bracket member 11, the complexity of the structure of the cover main body 1 can be effectively reduced, the manufacturing cost can be reduced, and at the same time, the assembly of the opening and closing structure of this case can be made more convenient.
[0042] As Figures 1 to 7 shown, preferably, the limit baffle 7 is also provided on the bracket member 11.
[0043] As Figure 2 shown, specifically, one end of the torsion spring 61 abuts against the movable cover 5 and the other end abuts against the bracket member 11.
[0044] As described above, the present case protects an automatic opening and closing structure of a rice bucket cover, and all technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
