DETAILED DESCRIPTION

[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figure 1-Figure 5 The utility model discloses an automatic feeding structure, including a feeding seat 10 and an opening and closing member. A feeding bin 20 is provided at the bottom end of the feeding seat 10. Specifically, the feeding bin 20 is provided with a storage cavity and a discharge port 21, and the discharge port 21 is connected with the storage cavity. The above-mentioned opening and closing member includes an opening and closing plate 30 and a force-bearing plate, and the opening and closing plate 30 and the force-bearing plate are connected to each other. The opening and closing plate 30 is rotatably assembled with the feeding bin 20, and can close or open the discharge port 21 of the feeding bin 20 during the rotation process. The above-mentioned force-bearing plate can drive the opening and closing plate 30 to rotate under the action of an external force.

[0031] On the basis of the above structure, when the automatic feeding structure of the utility model is used, the automatic feeding structure can be applied to a blender such as a food supplement machine, a soybean milk machine or a juice machine. When in use, the material to be added in the middle can be placed in advance in the storage cavity in the feeding bin 20. At this time, the opening and closing plate 30 of the opening and closing member closes the discharge port 21 of the feeding bin 20, and the force plate can extend from the bottom end of the feeding bin 20. The feeding seat 10 is sealed at the opening position of the blending cup 70 of the blender, and the force plate extends into the blending cup 70.

[0032] After that, start the stirring component 80 on the mixer, and the stirring component 80 can stir the material in the stirring cup 70. During the stirring process, the material can generate a rotating fluid during the stirring process of the stirring component 80, and form a fluid impact force in the stirring cup 70. After the feeding seat 10 is sealed on the stirring cup 70, the force-bearing plate at the bottom end of the feeding bin 20 will extend into the stirring cup 70, and be impacted by the fluid impact force during the stirring process to push the force-bearing plate, and then drive the opening and closing plate 30 connected to the force-bearing plate to rotate. After the opening and closing plate 30 rotates, the opening and closing plate 30 can be rotated from the closed discharge port 21 position in the initial state to the open discharge port 21 position.

[0033] After the discharge port 21 is opened, the material in the storage cavity of the feeding bin 20 can be discharged through the discharge port 21 and fed into the mixing cup 70. At this time, the material in the mixing cup 70 can be mixed with the material discharged from the feeding bin through the discharge port 21 to achieve automatic feeding of ingredients. That is, during the mixing process, the opening and closing plate 30 is opened by the mixing impact force formed during the mixing of the materials. There is no need to take out the feeding seat 10 or stop the machine for feeding, which improves the mixing efficiency and also reduces the probability of the mixing cup 70 being opened in the middle and bringing in impurities that affect the taste.

[0034] Of course, after the stirring action is completed, the opening and closing plate 30 can also be reset so that the opening and closing plate 30 is re-closed at the discharge port 21 of the feeding bin 20 for the next material feeding preparation. The above-mentioned opening and closing plate 30 can be reset manually, or it can be reset by flushing the stirring cup 70 with the flushing fluid to impact the force-bearing plate in the reverse direction. It should be noted that there are multiple ways to reset the opening and closing plate 30.

[0035] In addition, when the above-mentioned opening and closing plate 30 opens and closes and rotates, the force on the force-bearing plate can also be provided by another pushing structure in the mixing cup 70, such as providing a push rod in the mixing cup 70 to push the force-bearing plate, etc., and the impact of the fluid generated by the stirring in the mixing cup 70 can simplify the structure, and when the stirring in the mixing cup 70 produces a vortex, it is generally a state where the materials are mixed to a certain degree. At this time, the vortex impact force impacts the force-bearing plate to realize the opening of the opening and closing plate 30, the time of feeding is appropriate, and the mixing effect is better.

[0036] Furthermore, the discharge port 21 in this embodiment is arranged on the side wall of the feeding bin 20, and the opening and closing plate 30 is rotatably mounted on the outer wall of the feeding bin 20, that is, the opening and closing plate 30 can slide with the outer wall of the feeding bin 20. When the opening and closing plate 30 rotates, the discharge port 21 on the side wall of the feeding bin 20 can be opened or closed, and the above-mentioned force-bearing plate is connected to the bottom end of the opening and closing plate 30.

[0037] Since the force-bearing plate is connected to the bottom end of the opening and closing plate 30, it is used to extend into the stirring cup 70 after being assembled to the stirring cup 70 to be impacted by the fluid in the stirring cup 70. If the discharge port 21 is set at the bottom end of the feeding bin 20, after the opening and closing plate 30 is opened, the material in the storage cavity will fall from the bottom end into the stirring cup 70, which is easy to fall onto the force-bearing plate, causing the material to scatter. Therefore, in this embodiment, the discharge port 21 is set on the side wall of the feeding bin 20, and the opening and closing plate 30 rotates on the side wall of the feeding bin 20 to open the discharge port 21, and the force-bearing plate is located at the bottom end of the feeding bin 20. After the discharge port 21 is opened, the material falls from the side, reducing interference during the material falling process.

[0038] Furthermore, the opening and closing plate 30 includes an arc plate segment 31 and a connecting plate segment 32. When assembled, the arc plate segment 31 of the opening and closing plate 30 can be rotatably sleeved on the outer wall of the feeding bin 20 and rotated with the outer arc of the feeding bin 20. The connecting plate segment 32 can be connected to the bottom end of the arc plate segment 31. The connecting plate segment 32 can rotate with the bottom end of the feeding bin 20 through a rotating shaft, and then the force-bearing plate is connected to the connecting plate segment 32. In this way, the force-bearing plate is stressed, which can push the connecting plate segment 32 to rotate, and then the arc plate segment 31 connected to the connecting plate segment 32 is linked to rotate. Since the arc plate segment 31 matches the outer arc of the feeding bin 20, the rotation is smoother, and when the discharge port 21 of the feeding bin 20 is closed, the arc plate segment 31 can better match and fit with the outer wall of the feeding bin 20, reduce the assembly gap, and thus prevent the leakage of materials in the storage cavity after closing.

[0039] More specifically, a spiral guide surface 22 can be provided at the bottom end of the feeding bin 20, and the connecting plate segment 32 can be located in the extension direction of the spiral guide surface 22. Based on this structure, in addition to impacting the force-bearing plate to drive the connecting plate segment 32 to rotate, part of the fluid in the mixing cup 70 can also be guided by the spiral guide surface 22 to form a spiral vortex on the bottom end surface of the feeding bin 20, pushing the connecting plate segment 32 located in its extension direction, and superimposing the force on the force-bearing plate so that the arc plate segment 31 is easier to be pushed.

[0040] Furthermore, a guide plate section 23 is provided on the circumference of the bottom end of the feeding bin 20, and the guide plate section 23 is arranged around the outer circumference of the spiral guide surface 22, so that the guide plate section 23 and the spiral guide surface 22 can semi-enclose to form a spiral drainage space. After the rotating fluid in the stirring cup 70 flows to the spiral guide surface 22, it is blocked by the guide plate section 23. After being guided by the spiral guide surface 22, a larger vortex fluid can be formed at the bottom end of the feeding bin 20, which has a greater impact force on the connecting plate section 32 and is easier to drive the arc plate section 31 to rotate.

[0041] Furthermore, a first limiting step 24 and a second limiting step 25 may be provided on the outer side wall of the feeding bin 20. Specifically, the first limiting step 24 and one side wall of the discharge port 21 are spaced apart in the rotation direction of the opening and closing plate 30, and the second limiting step 25 is connected with the other side wall of the discharge port 21; the opening and closing plate 30 is used to abut against the first limiting step 24 or the second limiting step 25. In this way, when the opening and closing plate 30 rotates to close the discharge port 21, the side edge of the opening and closing plate 30 can abut against the second limiting step 25, that is, the opening and closing plate 30 can just rotate to a state where the discharge port 21 is completely closed. When the discharge port 21 is rotated to open, the opening and closing plate 30 can be rotated until the edge on the other side abuts against the first limiting step 24. In this way, the rotation position of the opening and closing plate 30 is limited by the first limiting step 24 and the second limiting step 25. That is, the opening and closing plate 30 will not rotate to a position that deviates too far from the discharge port 21, and can adapt to the rotation range formed by the swirl impact force in the mixing cup 70 to push the force-bearing plate.

[0042] It should be noted that, in this embodiment, the spacing distance between the first limiting step 24 and a side wall of the discharge port 21 can just match the width of the opening and closing plate 30, so that when the opening and closing plate 30 is rotated to abut against the first limiting step 24, the discharge port 21 can be just fully opened.

[0043] Furthermore, the above-mentioned force-bearing plate includes a first force-bearing plate segment and a second force-bearing plate segment. Specifically, the first force-bearing plate segment extends radially and is connected to the connecting plate segment 32, while the second force-bearing plate segment extends axially and is connected to the end of the first force-bearing plate segment. In this way, the force-bearing plate has radial and axial force-bearing plate segments, and the formed force surface is larger, which is more easily impacted by the stirring fluid in the stirring cup 70, and the opening and closing plate 30 is more easily pushed open.

[0044] Furthermore, an assembly channel 11 may be provided at the bottom end of the feeding seat 10, and specifically, a first step edge 111 and a limit buckle 113 may be provided at the bottom end of the assembly channel 11, and the limit buckle 113 may be provided above the first step edge 111 and spaced apart. Corresponding to the second step edge 26 of the feeding bin 20, the feeding bin 20 is loaded through the assembly channel 11, so that the second step edge 26 abuts against the first step edge 111, and the limit buckle 113 abuts against the second step edge 26.

[0045] Based on the above structure, the feeding bin 20 can be detachably assembled with the assembly channel 11 of the feeding seat 10. Specifically, during assembly, the bottom end of the feeding bin 20 can be inserted into the assembly channel 11 from top to bottom. After insertion, the second step edge 26 at the top of the feeding bin 20 can press the limit buckle 113 and cross the limit buckle 113 to be snapped into the gap between the limit buckle 113 and the first step edge 111. In this way, the position of the feeding bin 20 in the assembly channel 11 can be limited by the limit opening and the first step edge 111 respectively at the top and bottom to prevent axial separation.

[0046] It should be noted that the above-mentioned limit buckle 113 can be selected as a buckle, and the top of the buckle can be an inclined surface, which is convenient for the feeding bin 20 to be pressed against the feeding bin 20 when the feeding bin 20 is in a downward state, and is convenient for the second step edge 26 to be locked in.

[0047] More specifically, a limit column 112 can be provided on the inner wall of the assembly channel 11, and a limit hole 27 can be provided on the second step edge 26. When the feeding bin 20 is installed into the assembly channel 11, the limit column 112 can correspond to the position of the limit hole 27. When installed, the limit column 112 can be connected to the limit hole 27 to prevent the feeding bin 20 from rotating relative to the assembly channel 11. That is, circumferential limitation can be achieved by the limit insertion of the limit column 112 and the limit hole 27. The assembly structure of the feeding bin 20 is more stable, which prevents the feeding bin 20 from rotating when the opening and closing plate 30 rotates.

[0048] It should be noted that the above-mentioned limit buckles 113 can be arranged in plurality on the circumference of the assembly channel 11, and the plurality of limit buckles 113 can be distributed at intervals above the first step edge 111. After the feeding bin 20 is assembled, the plurality of limit buckles 113 can be evenly distributed above the second step edge 26, and the upper and lower limit structures formed are more stable.

[0049] Similarly, the above-mentioned limiting posts 112 and limiting holes 27 can be provided in plurality, and the plurality of limiting posts 112 and the plurality of limiting holes 27 can be distributed in the circumferential direction, so that the plurality of limiting posts 112 and the plurality of limiting holes 27 can realize multi-point limiting in the circumferential direction after being inserted and limited.

[0050] Embodiment 2,

[0051] See also Figure 1-Figure 6 The present embodiment provides a blender, including a machine base 60, a blending cup 70 and the automatic feeding structure in Embodiment 1, wherein the feeding base 10 is sealed to the top opening of the blending cup 70. Specifically, the blending cup 70 is detachably mounted on the machine base 60, and the detachable assembly of the blending cup 70 and the machine base 60 can be threaded assembly, or can be assembled by screws, or assembled by buckles.

[0052] Specifically, a stirring assembly 80 is provided on the machine base 60 , and the stirring assembly 80 is used to stir the materials in the stirring cup 70 , and the force-bearing plate can be impacted by the fluid when the materials in the stirring cup 70 rotate, so as to drive the opening and closing plate 30 to rotate.

[0053] When in use, the material to be added can be placed in advance in the storage cavity of the feeding bin 20, and the opening and closing plate 30 of the opening and closing member closes the discharge port 21 of the feeding bin 20, and the force plate can extend from the bottom end of the feeding bin 20. The feeding seat 10 is sealed at the opening position of the mixing cup 70 of the blender, and the force plate extends into the mixing cup 70.

[0054] After that, start the stirring component 80 on the mixer, and the stirring component 80 can stir the material in the stirring cup 70. During the stirring process, the material can generate a rotating fluid during the stirring process of the stirring component 80, and form a fluid impact force in the stirring cup 70. After the feeding seat 10 is sealed on the stirring cup 70, the force-bearing plate at the bottom end of the feeding bin 20 will extend into the stirring cup 70, and be impacted by the fluid impact force during the stirring process to push the force-bearing plate, and then drive the opening and closing plate 30 connected to the force-bearing plate to rotate. After the opening and closing plate 30 rotates, the opening and closing plate 30 can be rotated from the closed discharge port 21 position in the initial state to the open discharge port 21 position.

[0055] After the discharge port 21 is opened, the material in the storage cavity of the feeding bin 20 can be discharged through the discharge port 21 and fed into the mixing cup 70. At this time, the material in the mixing cup 70 can be mixed with the material discharged from the feeding bin through the discharge port 21 to achieve automatic feeding of ingredients. That is, during the mixing process, the opening and closing plate 30 is opened by the mixing impact force formed during the mixing of the materials. There is no need to take out the feeding seat 10 or stop the machine for feeding, which improves the mixing efficiency and also reduces the probability of the mixing cup 70 being opened in the middle and bringing in impurities that affect the taste.

[0056] Of course, after the stirring action is completed, the opening and closing plate 30 can also be reset so that the opening and closing plate 30 is re-closed at the discharge port 21 of the feeding bin 20 for the next material feeding preparation. The above-mentioned opening and closing plate 30 can be reset manually, or it can be reset by flushing the stirring cup 70 with the flushing fluid to impact the force-bearing plate in the reverse direction. It should be noted that there are multiple ways to reset the opening and closing plate 30.

[0057] In addition, when the above-mentioned opening and closing plate 30 opens and closes and rotates, the force on the force-bearing plate can also be provided by another pushing structure in the mixing cup 70, such as providing a push rod in the mixing cup 70 to push the force-bearing plate, etc., and the impact of the fluid generated by the stirring in the mixing cup 70 can simplify the structure, and when the stirring in the mixing cup 70 produces a vortex, it is generally a state where the materials are mixed to a certain degree. At this time, the vortex impact force impacts the force-bearing plate to realize the opening of the opening and closing plate 30, the time of feeding is appropriate, and the mixing effect is better.

[0058] It should be noted that the stirring assembly 80 may include a driving member and a stirring knife or a stirring blade. The driving member drives the stirring knife or the stirring blade to rotate in the stirring cup 70, so that the material in the stirring cup 70 can be stirred.

[0059] Furthermore, since the automatic feeding structure in this embodiment is the same as that in Embodiment 1, when the automatic feeding structure is applied to the mixer in this embodiment, the assembly structure, working principle and effect are the same as those in Embodiment 1, and will not be described in detail here.

[0060] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
