Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a coffee bean hopper rotation positioning structure and a coffee machine. Background Technology

[0002] In existing coffee grinders, the bean hopper is typically mounted on the grinding chamber of the machine body. When the hopper rotates, it simultaneously activates the bean sealing assembly at the bottom of the hopper to open or close the bean outlet. The hopper and / or grinding chamber are equipped with a limiting structure to restrict the rotation angle of the hopper. During use, when the user rotates the hopper until it is stopped by the limiting structure, it can be determined that the hopper has reached its designated position.

[0003] However, when the bean hopper gets stuck, the user cannot rotate it. Since there is no rotation indicator on the machine, the user may mistakenly believe that the bean hopper has been rotated to the correct position, which is quite troublesome. Utility Model Content

[0004] To overcome the defects described in the prior art, this utility model provides a bean hopper rotation positioning structure and a coffee machine. By setting a positioning structure between the bean hopper body and the lower cover plate, when the user rotates the bean hopper body until it is in position, the elastic column can abut against the positioning slot and make a sound, so that the user knows that the bean hopper body has been rotated into position, thereby avoiding misjudgment by the user, which is relatively simple and convenient.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A rotating positioning structure for a soybean hopper includes:

[0007] The main body of the bean hopper has a lower bean opening at its bottom;

[0008] A lower cover plate is installed at the bottom of the bean hopper body; the lower cover plate has a bean drop hole that connects to the bean drop opening;

[0009] The blade is disposed between the lower bean inlet and the bean drop hole and is connected to the bean hopper body in a driving connection.

[0010] It also includes a positioning structure disposed between the bean hopper body and the lower cover plate. The positioning structure includes an elastic post and a positioning slot that cooperates with the elastic post. One of the elastic post and the positioning slot is disposed on the bean hopper body, and the other is disposed on the lower cover plate.

[0011] When the bean hopper body rotates relative to the lower cover plate, the blades can rotate synchronously until the elastic column abuts against the positioning slot and makes a sound. At this time, the bean hopper body is limited and fixed, and the blades fully open or fully close the connection between the bean outlet and the bean drop hole.

[0012] Furthermore, the elastic post includes a positioning post and an elastic element that cooperates with the positioning post. Under the elastic force of the elastic element, the positioning post can be driven to extend into the positioning slot.

[0013] Furthermore, the elastic element is a spring, wherein:

[0014] The lower cover plate has an installation groove, and the spring and part of the positioning post are both disposed in the installation groove; one end of the spring abuts against the positioning post, and the other end abuts against the inner wall of the installation groove.

[0015] The positioning slot is formed on the bean hopper body; under the elastic force of the spring, the positioning post can be driven to extend into the positioning slot and abut against the bottom wall of the positioning slot; when the bean hopper body is driven to rotate relative to the lower cover plate, the positioning slot can be driven to rotate relative to the positioning post until the positioning post abuts against the side wall of the positioning slot and makes a sound, at which point the bean hopper body is limited and fixed.

[0016] Furthermore, the positioning slot is provided with a protrusion. When the bean hopper body is rotated relative to the lower cover plate, the elastic column can pass over the protrusion and abut against the positioning slot.

[0017] Furthermore, the positioning slot is provided with guide portions on both sides of the protrusion, and the elastic post can pass over the protrusion by being guided by the guide portions.

[0018] Furthermore, the guide portion is a guide slope or a guide arc surface.

[0019] Furthermore, one end of the blade is connected to the bean hopper body via a transmission connection, and the other end is slidably engaged with the lower cover plate via a groove block sliding structure.

[0020] Furthermore, the sliding structure of the groove includes a groove and a slider that is engaged in the groove and slides with the groove. One of the lower cover plate and the blade is provided with the groove, and the other is provided with the slider.

[0021] In addition, this utility model also provides a coffee machine, including a machine body and the aforementioned bean hopper rotation positioning structure disposed on the machine body, wherein a grinding chamber is provided on the machine body, and the bean hopper body is detachably assembled to the grinding chamber.

[0022] Furthermore, the grinding chamber is provided with anti-rotation protrusions, and the lower cover plate is provided with grooves that engage with the anti-rotation protrusions;

[0023] When the bean hopper body is placed on the grinding chamber and the anti-rotation protrusion engages with the groove, the lower cover plate is fixed in place. Subsequently, the bean hopper body can rotate relative to the lower cover plate.

[0024] In summary, the coffee maker and bean hopper rotation positioning structure of this utility model have the following beneficial effects:

[0025] (1) The bean hopper rotation positioning structure of this utility model sets a positioning structure between the bean hopper body and the lower cover plate. When the user drives the bean hopper body to rotate until it rotates to the position, the elastic column can abut against the positioning slot and make a sound, so that the user knows that the bean hopper body has rotated to the position, thereby avoiding misjudgment by the user. It is relatively simple and convenient.

[0026] (2) The bean bin rotation positioning structure of this utility model can initially restrict the elastic column by setting a protrusion on the positioning slot to prevent the bean bin body from deflecting due to slight vibration; in addition, by setting guide parts on both sides of the protrusion, it is convenient to drive the elastic column over the protrusion to avoid jamming.

Detailed Implementation

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Example 1

[0038] See Figure 1-4 This utility model provides a rotating positioning structure for a bean hopper, including a bean hopper body 1, a lower cover plate 2 installed at the bottom of the bean hopper body 1, and a plurality of blades 3 disposed between the bean hopper body 1 and the lower cover plate 2; wherein, a bean outlet 11 is provided at the center of the bottom of the bean hopper body 1, and a plurality of bean dropping holes 21 are provided on the lower cover plate 2, which are arranged circumferentially and connected to the bean dropping hole 11; the plurality of blades 3 are arranged circumferentially and located between the bean dropping hole 11 and the bean dropping hole 21; the blades 3 are connected to the bean hopper body 1 in a transmission manner.

[0039] Therefore, when the bean hopper body 1 rotates relative to the lower cover plate 2, it simultaneously drives several blades 3 to rotate. Thus, when the bean hopper body 1 is loaded and tightened until it is in place, the blades 3 fully open the connection between the bean outlet 11 and the bean drop holes 21, thereby allowing the coffee beans to pass through (e.g., ...). Figure 4 (As shown); Similarly, when the bean hopper body 1 is unscrewed and removed until it is in place, several blades 3 completely close the connection between the bean outlet 11 and the bean drop hole 21, thereby blocking the coffee beans (as shown). Figure 3(As shown). Therefore, the bean hopper rotation positioning structure of this application realizes the function of dropping or sealing beans while loading and unloading the bean hopper body 1. It is convenient to use, has a simple structure, and low manufacturing cost.

[0040] Furthermore, it also includes a positioning structure disposed between the bean hopper body 1 and the lower cover plate 2. The positioning structure includes a positioning groove 13 disposed on an elastic post and cooperating with the elastic post. Specifically, the bean hopper body 1 has a first protrusion 12 in the middle, and the outer periphery of the first protrusion 12 is provided with several support strips to support and fix it on the bean hopper body 1. The bottom of the first protrusion 12 is provided with the aforementioned positioning groove 13. Similarly, the lower cover plate 2 is provided with a second protrusion 22 corresponding to the first protrusion 12. The second protrusion 22 is provided with the elastic post, and the elastic post extends into the positioning groove 13.

[0041] Therefore, when the bean hopper body 1 rotates relative to the lower cover plate 2 until the elastic column abuts against the positioning slot 13 and makes a sound, the user can know that the bean hopper body 1 has rotated into place, thus avoiding misjudgment by the user, which is relatively simple and convenient.

[0042] Of course, in other implementations, the positions of the elastic column and the positioning slot 13 can be interchanged to achieve the same technical effect, and there are no restrictions here.

[0043] The elastic column includes a positioning column 4 and an elastic element 5 that cooperates with the positioning column 4. Preferably, the elastic element 5 is a spring. The second protrusion 22 has a mounting groove 23. The spring and part of the positioning column 4 are both disposed in the mounting groove 23. One end of the spring abuts against the positioning column 4, and the other end abuts against the bottom wall of the mounting groove 23. Thus, under the elastic force of the spring, the positioning column 4 can be driven to extend into the positioning slot 13 and abut against the bottom wall of the positioning slot 13. When the bean hopper body 1 is rotated relative to the lower cover plate 2, the positioning slot 13 can be driven to rotate relative to the positioning column 4 until the positioning column 4 abuts against the side wall of the positioning slot 13 and makes a sound. At this point, the bean hopper body 1 is limited and fixed.

[0044] In this embodiment of the utility model, in order to increase the impact sound of the positioning post 4 and the positioning slot 13, the positioning post 4 and the first protrusion 12 can be made of metal, so that they make a louder sound when they come into contact.

[0045] In this embodiment of the utility model, the positioning structure can be provided in multiple sets and arranged circumferentially between the first boss 12 and the second boss 22, so as to improve the positioning reliability of the positioning structure.

[0046] See also Figure 2The positioning slot 13 has a protrusion 131. When the bean hopper body 1 rotates relative to the lower cover plate 2, the protrusion 131 can abut against the positioning post 4. At this time, the user needs to use a certain amount of force to rotate the bean hopper body 1 so that the protrusion 131 can drive the positioning post 4 to overcome the spring force and move past the protrusion 131. It can be seen that by setting the protrusion 131 on the positioning slot 13, the movement of the elastic post can be restricted to prevent the bean hopper body 1 from deflecting due to slight vibration, thereby ensuring the stability of the bean hopper body 1.

[0047] Furthermore, the positioning slot 13 is provided with guide portions 132 on both sides of the protrusion 131, allowing the positioning post 4 to more easily pass over the protrusion 131. Preferably, the guide portion 132 is a guide slope. Thus, by providing guide portions 132 on both sides of the protrusion 131, it is easier to drive the elastic post over the protrusion 131, avoiding jamming due to height difference.

[0048] Of course, in other embodiments, the guide portion 132 can also be a guide arc surface, which can also guide the positioning post 4 over the protrusion 131, and there are no restrictions here.

[0049] See also Figure 1-2 The blade 3 has a mounting hole 31 at one end, and the bottom of the bean hopper body 1 has a mounting post 14. The blade 3 is hinged to the mounting post 14 through the mounting hole 31 to achieve a transmission connection. The other end of the blade 3 is slidably engaged with the lower cover plate 2 through a groove block sliding structure.

[0050] Specifically, the sliding structure of the slot includes a groove 32 formed on the blade 3 and a slider 24 set on the lower cover plate 2 and slidably engaged in the groove 32. Thus, when the bean hopper body 1 is rotated, the groove 32 can be driven to slide along the slider 24 to realize the rotation of the blade 3, thereby opening or closing the connection between the lower bean opening 11 and the bean dropping hole 21.

[0051] Of course, in other embodiments, the positions of the slide groove 32 and the slider 24 can be interchanged to achieve the same rotation effect, and there is no limitation here.

[0052] Example 2

[0053] See Figure 5 The present invention also provides a coffee machine, including a body and a bean hopper rotation positioning structure as described in Embodiment 1, wherein the body has a grinding chamber 6, and the bean hopper body 1 is detachably screwed into the grinding chamber 6.

[0054] The grinding chamber 6 is provided with an anti-rotation protrusion 61, and the lower cover plate 2 is provided with a groove 25 that engages with the anti-rotation protrusion 61. Thus, when the bean hopper body 1 is placed on the grinding chamber and the anti-rotation protrusion 61 engages with the groove 25, the lower cover plate 2 is fixed in place. Subsequently, the bean hopper body 1 can rotate relative to the lower cover plate 2.

[0055] In summary, the coffee maker and bean hopper rotation positioning structure of this utility model have the following beneficial effects:

[0056] (I) The bean hopper rotation positioning structure of this utility model sets a positioning structure between the bean hopper body 1 and the lower cover plate 2. When the user drives the bean hopper body 1 to rotate until it rotates to the position, the elastic column can abut against the positioning slot 13 and make a sound, so that the user knows that the bean hopper body 1 has rotated to the position, thereby avoiding misjudgment by the user. It is relatively simple and convenient.

[0057] (II) The rotating positioning structure of the bean bin of this utility model can initially restrict the elastic column by setting a protrusion 131 on the positioning slot 13 to prevent the bean bin body 1 from deflecting due to slight vibration; in addition, by setting guide parts 132 on both sides of the protrusion 131, it is convenient to drive the elastic column over the protrusion 131 to avoid jamming.

[0058] 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.
