Description

Technical Field

[0001] This utility model relates to the field of coffee bean processing technology, and in particular to an anti-static coffee grinder. Background Technology

[0002] A coffee grinder is a specialized appliance used to grind coffee beans into coffee powder. It is one of the core pieces of equipment in coffee making, and its grinding effect directly affects the extraction rate and final taste of the coffee. Coffee grinders grind whole coffee beans into powders of varying coarseness, either mechanically or manually. During the grinding process, friction between the coffee beans and the burrs / grips generates static electricity, which can cause coffee powder to adhere to the inner wall of the grinder, scatter, or clump. Clumped coffee powder creates density differences during tamping, leading to uneven water flow during brewing. This can easily cause localized over-extraction resulting in bitterness or under-extraction, resulting in a weak and acidic taste. Scattered powder also causes fine particles to fall off, resulting in the loss of aroma compounds and affecting the coffee's concentration and flavor consistency. Furthermore, the coffee powder residue adhering to the inner wall needs to be manually cleaned, increasing the workload for the operator.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN202321134797.5, patent name: a coffee grinder that can eliminate static electricity) is as follows: the coffee powder produced by the grinding device is collected in the container. One end of the grounding conductive component is abutted against the metal base plate, and the other end is used for grounding. The static electricity in the coffee powder can be conducted to the ground through the metal base plate-grounding conductive component, effectively neutralizing the charge in the coffee powder, removing static electricity, making it convenient for users to pour out the coffee powder, reducing the user's cleaning work, and improving the user experience.

[0004] As can be seen from the above implementation plan and corresponding drawings, it uses a grounding conductive component to conduct the static electricity of the coffee powder in the container to the ground via a metal base plate, thereby neutralizing the charge and reducing residue. However, this solution only eliminates static electricity in the coffee powder stored in the container and cannot solve the problem of static electricity already generated in the output channel, which can easily lead to channel blockage and hinder equipment cleaning. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides an anti-static coffee grinder, which is equipped with positive and negative electrodes of a plasma generator and a feed channel baffle to force coffee powder to flow through the positive and negative electrode areas, avoiding uneven ion contact caused by a single channel and enhancing the static electricity elimination rate.

The bean box assembly includes a box body, and a box body sinking baffle is provided at the lower part of the box body.

[0011] By rotating the diverter plate, the perforated areas of the plate and the recessed baffles in the housing form an alternating covering structure, dynamically adjusting the size of the holes through which the coffee beans pass.

[0012] Furthermore, a diverter rod is connected to the center of the diverter plate, and a twist handle is provided at the end of the diverter rod away from the diverter plate. A protective umbrella is connected to the lower end of the twist handle.

[0019] Furthermore, the outer grinding tool is nested within a tool sleeve, which is equipped with a pull ring and is detachably connected to an outer adjustment assembly.

[0020] Furthermore, the inner grinding blade is connected to a central rotating shaft, which in turn is connected to a powder pushing component. The powder pushing component is equipped with at least one powder pushing blade and is rotatably connected to a powder storage base.

[0021] Furthermore, the external adjustment group includes an adjusting outer ring, which is meshed with a linkage rotating ring.

[0042] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0043] like Figures 1 to 10 As shown, an anti-static coffee grinder includes a bean box assembly 1, a grinding assembly 3 connected to the lower end of the bean box assembly 1, an external adjustment group 4 connected to the grinding assembly 3, and an external adjustment group 4 including a feeding base 407, a feeding port 4072 provided on the feeding base 407, a discharge cylinder 6 connected to the feeding port 4072, a plasma generator positive and negative electrode 4073 provided on the upper part of the feeding base 407, and a distribution plate 601 provided on the upper end of the discharge cylinder 6.

[0044] Coffee beans are ground into powder in the bean box assembly 1 by the grinding assembly 3 and then output through the discharge cylinder 6. During output, the coffee powder is supported by the distribution plate 601, so that the coffee powder can indirectly or directly contact the positive and negative electrodes 4073 of the plasma generator, thereby eliminating the static electricity carried by the coffee powder.

[0045] The grinding assembly 3 is equipped with a powder storage seat 303, which is embedded in the feeding base 407. The powder storage seat 303 is made of metal. In addition to its supporting and powder guiding functions, the powder storage seat 303 can also help release some static electricity through its grounding design, forming a synergistic anti-static effect with the plasma generator.

[0046] The powder storage holder 303 is equipped with a powder outlet 3031. The powder outlet 3031 and the feed inlet 4072 are arranged concurrently. The feed inlet 4072 is equipped with a diverting feed baffle 40721, which divides the feed inlet 4072 into two parts, so that the two small holes correspond to the positive and negative electrodes of the plasma generator 4073, respectively. When coffee powder falls from the powder outlet 3031, it is divided into two streams by the diverting feed baffle 40721, flowing through the positive and negative electrode areas respectively. At this time, the plasma... The positive and negative ion streams generated by the plasma generator come into full contact with the coffee powder, neutralizing the static charge generated on its surface by friction. At the same time, the distribution plate 601 at the upper end of the discharge cylinder 6 buffers and disperses the falling coffee powder: some coffee powder bounces back after directly hitting the distribution plate 601, indirectly contacting the positive and negative electrodes 4073 of the plasma generator; the processed coffee powder slides smoothly down the inner wall of the discharge cylinder 6, effectively avoiding the problems of adsorption, scattering or clumping on the inner wall caused by static electricity, ensuring uniform powder output and no residue, and significantly reducing the difficulty of cleaning.

[0047] By setting up positive and negative electrodes 4073 for the plasma generator and a feed divider 40721, the coffee powder is forced to flow through the positive and negative electrode areas, avoiding uneven ion contact caused by a single channel and enhancing the static electricity elimination rate.

[0048] By using the tray 601, some coffee powder is physically dispersed and comes into contact with secondary ions, solving the problem of static electricity that is difficult to eliminate in traditional equipment. It is especially suitable for anti-static treatment of finely ground coffee powder, realizing full anti-static treatment of coffee powder in the output channel, improving the ease of use of the equipment and the quality stability of coffee powder.

[0049] The bean box assembly 1 is provided with a diversion mechanism 2 inside, the diversion mechanism 2 is provided with a diversion plate 202, and the diversion plate 202 has a plate body hollowed-out position 2021 at intervals on the plate surface. The bean box assembly 1 includes a box body 101, and a box body sinking baffle 1011 is provided at the lower part of the inside of the box body 101.

[0050] By rotating the diverter plate 202, the perforated area 2021 of the plate and the recessed baffle 1011 of the housing form an alternating covering structure, dynamically adjusting the size of the coffee beans passing through the holes. This allows control over the number of coffee beans falling onto the grinding assembly 3 each time. Furthermore, before starting the grinding mode, because some parts of the grinding assembly 3 are blocked by the recessed baffle 1011, the space between the inner and outer grinding blades 304 in this part will not be filled with coffee beans, reducing the resistance when the motor 501 starts. This design effectively avoids the impact of high torque on the motor 501, extending the motor's lifespan.

[0051] The center of the diverter plate 202 is connected to the diverter rod 201. The end of the diverter rod 201 away from the diverter plate 202 is provided with a twist handle 204. The lower end of the twist handle 204 is connected to the protective umbrella 203. The protective umbrella 203 can prevent coffee beans from scattering in all directions when they are ground by the grinding component 3, so that the coffee beans are more concentrated, thereby improving the grinding efficiency and the uniformity of grinding.

[0052] The outer adjustment group 4 is used to adjust the relative position of the outer grinding blade 302 and the inner grinding blade 304 in the vertical direction. The grinding assembly 3 includes an outer grinding blade 302 and an inner grinding blade 304 arranged coaxially. The outer grinding blade 302 includes a first upper blade 3021 and a first lower blade 3022, both arranged in a ring shape with teeth on the inner surface of the ring. The inner cavity of the first upper blade 3021 is an inverted frustum shape, and the inner cavity of the first lower blade 3022 is a frustum shape. The teeth of the first upper blade 3021 are larger than the teeth of the first lower blade 3022. The inner grinding blade 304 includes a second upper blade 3041 and a second lower blade 3042, which together form a frustum. The shape of the upper blade 3041 is such that the teeth of the upper blade 3041 are larger than those of the lower blade 3042. When grinding coffee beans, the height of the upper blade 3021 can be adjusted to be level with that of the lower blade 3041, increasing the capacity of the grinding assembly 3 to hold the coffee beans and allowing more beans to be ground. When grinding enters the middle and later stages, the relative height of the outer grinding blade 302 and the inner grinding blade 304 in the vertical direction can be adjusted by rotating the outer ring 401, making the gap between the lower blade 3022 and the lower blade 3042 smaller, thereby grinding the coffee beans more finely.

[0053] The lower end of the grinding assembly 3 is connected to the power assembly 5, which provides power to the grinding assembly 3.

[0054] The outer grinding blade 302 is nested in the blade sleeve 301. The blade sleeve 301 is provided with a pull ring 3011. The blade sleeve 301 is detachably connected to the outer adjustment assembly 4. When the outer grinding blade 302 needs to be removed, simply pull up the pull ring 3011 and then rotate the blade sleeve 301 to disengage the blade sleeve 301 from the lifting inner support 405, thereby quickly removing the blade sleeve 301 and the outer grinding blade 302. This makes it convenient for the user to clean the grinding blade and other components inside the grinding assembly 3. Due to the frustum structure of the inner grinding blade 3, the outer grinding blade 302 can be very close to the inner grinding blade, but the two will not interfere with each other during disassembly.

[0055] A micro switch 408 is installed inside the feed base 407. The contact rod of the micro switch 408 is located below the blade sleeve 301. When the blade sleeve 301 is connected to the lifting inner support 405, the micro switch 408 is activated, and the grinder can enter the working state. When the blade sleeve 301 is separated from the lifting inner support 405, the micro switch 408 is not activated, and the grinder cannot work after being powered on. This ensures that the grinder will not be misoperated and also prevents accidental hand injury when the parts are not fully installed.

[0056] The internal grinding blade 304 is connected to the central rotating shaft 306, and the central rotating shaft 306 is connected to the powder pushing component 305. The powder pushing component 305 is provided with at least one powder pushing blade 3051. The powder pushing component 305 is rotatably connected to the powder storage seat 303. The powder storage seat 303 is provided with a powder outlet 3031. The powder storage seat 303 is made of metal and has the function of eliminating static electricity in the coffee powder, so that the coffee powder is output more smoothly after being ground, and the powder will not stick together due to static electricity.

[0057] The ground coffee powder falls into the powder storage base 303. When the central rotating shaft 306 rotates, it drives the powder pushing component 305 to rotate. Therefore, when the powder pushing blade 3051 rotates around the powder storage base 303, it pushes the coffee powder. When the coffee powder is pushed to the powder outlet 3031, it can fall out from the powder outlet 3031.

[0058] The outer adjustment group 4 includes an adjusting outer ring 401, which is meshed with a linkage rotating ring 402. The linkage rotating ring 402 is engaged with a lifting adjusting gear seat 406. The lifting adjusting gear seat 406 has a lifting inner support 405 coaxially threaded inside, and the lifting inner support 405 is connected to the tool sleeve 301. The inner wall of the lifting adjusting gear seat 406 is provided with a vertical adjusting thread 4061, and the outer wall is provided with a linkage gear ring 4062. At least one engaging block 604 is provided on the outer side of the linkage gear ring 4062. 3. Therefore, when the adjusting outer ring 401 is rotated by hand, the internal gear at the bottom of the adjusting outer ring 401 meshes with the external gear at the top of the linkage ring 402. The linkage ring 402 has an insert inside at the bottom, which is inserted into the linkage gear ring 4062. This can drive the lifting adjusting gear seat 406 to rotate, thereby connecting the vertical adjusting thread 4061 with the vertical thread of the outer ring of the lifting inner support 405, thus adjusting the lifting of the lifting inner support 405, and in turn driving the tool sleeve 301 to rise and fall.

[0059] The outer casing 8 has a feeding base 407 inside, and a sliding insertion post 4071 is provided at the upper end of the feeding base 407. The powder storage seat 303 is provided in the feeding base 407. A feeding port 4072 is provided on one side of the lower end of the feeding base 407. The feeding port 4072 is arranged to coincide with the powder outlet 3031. The powder outlet 3031 is connected to the discharge cylinder 6. The sliding insertion post 4071 is slidably inserted into the lifting inner support 405. The sliding insertion post 4071 allows the lifting inner support 405 to move along the guide of the sliding insertion post 4071 when it is lifted, making the lifting inner support 405 more stable when it is lifted.

[0060] A first separator 403 and a second separator 404 are provided between the outer ring 401 and the housing 101. The first separator 403 and the second separator 404 separate the housing 101 from the external adjustment structure, which on the one hand enhances the strength of the entire coffee grinder, and on the other hand buffers the vibration of the coffee beans inside the housing 101, thereby reducing the noise when the coffee grinder is working.

[0061] The outer ring 401 is rotatably connected to the outer casing 8. The outer casing 8 is also equipped with a control panel 7. A powder receiving cup pad 10 is provided on one side of the lower end of the outer casing 8. A powder receiving cup retaining ring 9 is provided directly above the powder receiving cup pad 10. When receiving coffee powder, the powder cup is placed on the powder receiving cup pad 10 and secured in the powder receiving cup retaining ring 9. This not only frees the operator's hands but also makes the powder cup more stable, preventing the powder from falling unevenly and causing the powder cup to tip over.

[0062] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
