Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, and in particular to a blade cleaning assembly and a grinding device having the same. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The coffee making process is generally as follows: first, the coffee beans are ground into coffee powder using a coffee bean grinding device (such as a coffee bean grinder or a coffee machine), the coffee powder is then flattened in the powder bowl of the extraction handle, and finally hot water is added for extraction and filtration to make coffee liquid.

[0004] The existing coffee bean grinding device needs to clean the blade disc assembly in the grinding chamber in time after using it for a period of time, so as to avoid the residual powder remaining for too long and causing food safety hazards such as taste change and deterioration. Among them, the blade disc assembly usually includes an outer blade disc and an inner blade disc that cooperate with each other. The outer blade disc is usually detachable, so that the user can disassemble it for cleaning; while the inner blade disc is generally not detachable, so the user needs to use a brush to manually clean it, which is not only time-consuming and labor-intensive, but also because the inner blade disc is set in the grinding chamber, its space is relatively limited, so that some positions cannot be cleaned in place, and the cleaning effect is poor. In addition, when the swept residual powder falls to the bottom of the grinding chamber and is swept out to the powder outlet channel by the powder sweeping plate, since there is a certain gap between the powder sweeping blades of the powder sweeping plate and the bottom wall of the grinding chamber, it is impossible to completely sweep out all the residual powder that falls to the bottom of the grinding chamber, thereby causing residual powder to appear in the grinding chamber.

[0005] Therefore, further improvement is needed. Summary of the invention

[0006] In order to overcome the defects of the above-mentioned prior art, the present invention provides a blade disc cleaning assembly and a grinding device having the same, so as to solve the problems mentioned in the above-mentioned background technology, such as time-consuming and labor-intensive cleaning, poor cleaning effect of the inner blade disc, and easy occurrence of residual powder in the grinding chamber.

[0042] 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.

[0043] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the modules or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0044] 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 in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] See also Figure 1-8The present invention provides a grinding device. Preferably, the grinding device is a coffee brewing machine with a bean grinding device. The coffee brewing machine comprises a body 1, a grinding chamber 11 is provided on the body 1, a knife disc assembly for grinding coffee beans and a powder sweeping plate 13 arranged below the knife disc assembly and used for discharging powder are provided in the grinding chamber 11, the knife disc assembly comprises a detachable outer knife disc and an inner knife disc 12 that cooperates with the outer knife disc and is not detachable; in addition, it also comprises a bean bin that can be detachably screwed into and assembled on the grinding chamber 11 of the body 1.

[0046] Therefore, when the bean bin is assembled on the grinding chamber 11 and rotated into place, the bean bin is opened and the coffee beans in the bean bin fall into the grinding chamber 11. After the coffee brewing machine is started, the coffee beans can be ground into coffee powder under the action of the blade assembly, and the powder sweeping plate 13 can sweep the coffee beans into the powder outlet channel and flow out.

[0047] Among them, after the bean grinding device has been used for a period of time, the user needs to clean the blade assembly in the grinding chamber 11 in time. Therefore, the present application also includes a blade disc cleaning assembly 2 that can be detachably screwed into and assembled on the grinding chamber 11 of the machine body 1, and the blade disc cleaning assembly 2 includes a mounting seat 21, a cleaning cylinder 22 that is movably inserted into the mounting seat 21 and can move up and down to completely cover the outside of the inner blade disc 12, and a powder sweeping cylinder 24 that is rotatably sleeved on the bottom of the cleaning cylinder 22; wherein, the inner side wall of the cleaning cylinder 22 is provided with at least one group of first cleaning bristles 221 that are in contact with the outer wall of the inner blade disc 12, and the first cleaning bristles 221 are used to sweep the residues adhered to the outer wall of the inner blade disc 12 when the inner blade disc 12 rotates; the bottom wall of the powder sweeping cylinder 24 is provided with at least one group of second cleaning bristles 241 that are used to contact the bottom of the grinding chamber 11 and to cooperate with the powder sweeping plate 13 in transmission, and the second cleaning bristles 241 are used to drive the powder sweeping plate 13 to rotate together when it rotates and sweep the swept residues out to the powder outlet channel.

[0048] Therefore, when it is necessary to clean the inner blade disc 12, the bean bin assembled on the machine body 1 and the outer blade disc arranged in the grinding chamber 11 of the machine body 1 can be taken out first, and then the blade disc cleaning assembly 2 is installed on the grinding chamber 11 and the cleaning cylinder 22 is driven to move downward until it is completely covered on the outside of the inner blade disc 12. At this time, the second cleaning bristles 241 on the powder sweeping cylinder 24 are located on the outer peripheral side of the powder sweeping plate 13. Then, the coffee brewing machine is started and the inner blade disc 12 and the powder sweeping plate 13 are rotated at the same time. The first cleaning bristles 221 on the inner side wall of the cleaning cylinder 22 can clean the residue adhering to the inner blade disc 12 when the inner blade disc 12 rotates so that it falls to the bottom of the grinding chamber 11. The second cleaning bristles 241 on the bottom wall of the powder sweeping cylinder 24 can be driven by the powder sweeping plate 13 to rotate so as to completely sweep the residue that falls to the bottom of the grinding chamber 11 out to the powder outlet channel, thereby completing the cleaning.

[0049] Therefore, the blade disc cleaning assembly 2 of the present application is used for cleaning. Since the inner blade disc 12 can be automatically cleaned by rotating, it is relatively easy and labor-saving. In addition, the first cleaning bristles 221 in the cleaning tube 22 can perform all-round cleaning on the outer wall of the inner blade disc 12, avoiding the problem of residual powder on the inner blade disc 12, and achieving a better cleaning effect.

[0050] In addition, the blade cleaning assembly 2 of the present application also has the function of improving the utilization rate of the residual coffee beans in the grinding chamber 11. Specifically, when the bean bin assembled on the machine body 1 is taken out without disassembling the outer blade, there are still a small amount of residual beans in the grinding chamber 11 of the machine body 1. In order to avoid waste, the blade cleaning assembly 2 can be installed on the grinding chamber 11 and the coffee brewing machine can be started. The residual beans in the grinding chamber 11 can be ground into coffee powder under the action of the blade assembly and swept out to the powder outlet channel through the powder sweeping plate 13, thereby improving the utilization rate of the residual beans.

[0051] In addition, when it is necessary to explain, the grinding device of the present invention is also applicable to a separately arranged bean grinder or other powder grinding device. As long as the powder grinding device is involved, it falls within the protection scope of this application and is not limited here.

[0052] Preferably, the shape of the first cleaning bristles 221 in the cleaning cylinder 22 is adapted to the shape of the inner blade disc 12. In the embodiment of the present invention, the inner blade disc 12 is an inner cone blade disc that is narrow at the top and wide at the bottom, and the shape of the first cleaning bristles 221 is a cone. In this way, the first cleaning bristles 221 can better clean the residue and powder adhering to the inner blade disc 12, and the cleaning effect is better.

[0053] In the embodiment of the present invention, the first cleaning bristles 221 and the second cleaning bristles 241 are provided in multiple groups, and the multiple groups of first cleaning bristles 221 are all arranged on the inner side wall of the cleaning cylinder 22, and the multiple groups of second cleaning bristles 241 are all arranged on the bottom wall of the powder sweeping cylinder 24. Therefore, the multiple groups of first cleaning bristles 221 can increase the cleaning times of the inner blade disc 12, thereby further improving the cleaning effect of the inner blade disc 12; the multiple groups of second cleaning bristles 241 can better sweep out all the residual powder that falls into the bottom of the grinding chamber 11, and the cleaning effect is better.

[0054] See also Figure 2-3 as well as Figure 5 The outer wall of the powder sweeping tube 24 is also provided with at least one group of third cleaning bristles 242 for contacting the inner wall of the grinding chamber 11. Preferably, the third cleaning bristles 242 are provided with multiple groups, and the multiple groups of third cleaning bristles 242 are all arranged on the outer wall of the powder sweeping tube 24.

[0055] Therefore, by setting the third cleaning brush 242, when the powder sweeping plate 13 rotates and drives the powder sweeping cylinder 24 to rotate, the third cleaning brush 242 can clean a small amount of residual powder adhering to the inner wall of the grinding chamber 11 so that it falls to the bottom of the grinding chamber 11 and is finally cleaned out by the second cleaning brush 241, thereby ensuring the cleanliness of the grinding chamber 11.

[0056] Furthermore, the powder sweeping cylinder 24 can be rotatably set on the cleaning cylinder 22 through a clamping structure, and the clamping structure includes an annular clamping groove 224 opened on the outer wall of the cleaning cylinder 22 and a plurality of hooks 243 arranged on the top of the powder sweeping cylinder 24. The plurality of hooks 243 are all inserted into the annular clamping groove 224 and can rotate along the annular clamping groove 224, thereby realizing a rotational connection between the two.

[0057] See also Figure 3 and Figure 6 The cutter disc cleaning assembly 2 is detachably screwed into and assembled to the grinding chamber 11 of the machine body 1 through the mounting seat 21; specifically, the mounting seat 21 and the grinding chamber 11 of the machine body 1 are detachably matched through a snap-fit ​​structure, and the snap-fit ​​structure includes a slide groove 213 and a slider 14 that are snap-fitted with each other, the slide groove 213 is opened on the outer bottom wall of the mounting seat 21, and the slider 14 is arranged on the inner side wall of the grinding chamber 11 of the machine body 1, wherein a convex point 2131 is also provided on the slide groove 213, and a concave point 141 is also provided on the slider 14; therefore, when the mounting seat 21 is screwed into and assembled to the grinding chamber 11 through the sliding snap-fitting cooperation between the slide groove 213 and the slider 14 until the convex point 2131 on the slide groove 213 is snap-fitted with the concave point 141 on the slider 14, the mounting seat 21 is screwed into and assembled into place.

[0058] Of course, it should be noted that in other embodiments, the positions of the slide groove 213 and the slider 14, the protrusion 2131 and the concave point 141 may be interchanged, which can also achieve the same technical effect, and there is no limitation here.

[0059] Furthermore, the body 1 is also provided with a controller, a driving device and a sensor. The driving device drives the powder sweeping plate 13 and the inner blade disc 12 to rotate simultaneously; the driving device and the sensor are both electrically connected to the controller. Among them, the outer wall of the mounting seat 21 is provided with a trigger block 214. When the mounting seat 21 is screwed into the grinding chamber 11 and is in place, the trigger block 214 can trigger the sensor. At this time, the sensor sends a signal to the controller, and the controller can determine that the blade disc cleaning component 2 has been assembled in place; then the controller can control the drive device to move to drive the blade disc component and the powder sweeping plate 13 to move, thereby realizing the cleaning operation. Such a setting can prevent the blade disc cleaning component 2 from being started before it is assembled in place, thereby ensuring the safety of the user.

[0060] In this embodiment, the sensing element is a micro switch, and the micro switch and the trigger block 214 are connected through a connecting rod 15 to achieve transmission cooperation. The grinding chamber 11 is provided with an avoidance groove 16 for avoiding the trigger block 214, and one end of the connecting rod 15 extends out of the avoidance groove 16 to cooperate with the trigger block 214.

[0061] Furthermore, the mounting seat 21 is provided with a through slot 211 and a mounting slot 212 connected to the through slot 211 , the cleaning cylinder 22 is inserted into the through slot 211 , and a limiting device 23 for limiting the moving position of the cleaning cylinder 22 is provided in the mounting slot 212 .

[0062] Specifically, the limiting device 23 includes a mounting bracket 231 fixed in the mounting groove 212, a pressure rod 232 movably provided on the mounting bracket 231 and movable up and down, a limiting block 233 movably provided on the mounting bracket 231 and movable horizontally, a first elastic member 234 provided in the mounting bracket 231 and abutting against the limiting block 233, and a second elastic member 235 provided in the mounting bracket 231 and abutting against the pressure rod 232; wherein, the limiting block 233 and the pressure rod 232 are matched through an inclined plane transmission, and when the pressure rod 232 is driven to move downward, the limiting block 233 can be driven by the inclined plane to overcome the elastic force of the first elastic member 234 and shrink inwardly in the horizontal direction.

[0063] In addition, the outer wall of the cleaning cylinder 22 is provided with two limit slots 223 arranged at intervals in the upper and lower directions. Under the elastic force of the first elastic member 234, the limit block 233 can be driven to extend horizontally until it is aligned with the limit slot 223, and the limit block 233 is inserted into the limit slot 223 to realize the limiting fixation of the cleaning cylinder 22; when the pressure rod 232 is driven to move downward, the limit block 233 can be driven by the inclined surface to overcome the elastic force of the first elastic member 234 and shrink inwardly in the horizontal direction, so that the limit block 233 is separated from the limit slot 223, and the cleaning cylinder 22 can move up and down at this time.

[0064] Under the elastic force of the second elastic member 235, one end of the pressure rod 232 can be driven to extend out of the mounting bracket 231 for the user to press down. When the user presses down on the pressure rod 232, the pressure rod 232 can overcome the elastic force of the second elastic member 235 and move. When the user releases the external force, the pressure rod 232 can rebound and reset under the elastic force of the second elastic member 235.

[0065] Therefore, when the pressure rod 232 is pressed down and drives the cleaning cylinder 22 to move downward until the limit block 233 is inserted into the limit slot 223 at the bottom, the cleaning cylinder 22 completely covers the outside of the inner knife disc 12 and the first cleaning bristles 221 in the cleaning cylinder 22 contact the outer wall of the inner knife disc 12. At this time, a plurality of second cleaning bristles 241 on the bottom wall of the powder sweeping cylinder 24 are arranged around the outer periphery of the powder sweeping plate 13 and the second cleaning bristles 241 contact the bottom of the grinding chamber 11; the pressure rod 232 is pressed down and drives the cleaning cylinder 22 to move upward until the limit block 233 is inserted into the limit slot 223 at the top, and the cleaning cylinder 22 is separated from the inner knife disc 12.

[0066] In this embodiment, the first elastic member 234 and the second elastic member 235 are both springs.

[0067] In addition, the outer wall of the cleaning cylinder 22 is further provided with a guide slot 222 extending in the height direction, and the two limit slots 223 are both located in the guide slot 222. The limit block 233 is partially inserted into the guide slot 222 and slidably engaged therewith.

[0068] Therefore, the cleaning cylinder 22 can move up and down through the guide groove 222 and the sliding guide of the limit block 233, thereby improving the movement stability.

[0069] In summary, the blade cleaning assembly 2 and the grinding device having the same provided by the present invention have the following beneficial effects:
