Description

Technical Field

[0001] The utility model relates to the technical field of coffee grinding, in particular to a portable coffee grinding device. Background Art

[0002] The Chinese patent application document with the Chinese application publication number CN113854864A discloses a technical solution entitled "A portable coffee grinder and coffee grinding method", which includes the following technical features: a grinding barrel, the two ends of which are open structures, and a receiving cup is threadedly connected to the lower end of the grinding barrel. Since the receiving cup is threadedly connected to the lower end of the grinding barrel, the inner cavity of the receiving cup cannot be completely fitted on the grinding barrel. When the receiving cup is threadedly connected to the grinding barrel, the height of the entire coffee grinder will be relatively large. Even if the receiving cup and the grinding barrel are separated and placed separately, they will still occupy a large space, which will make the coffee grinder inconvenient to store and carry.

[0003] Although there are technical solutions for changing the overall volume of a coffee grinder by changing the nesting amount, for example, the patent document "A coffee grinder" disclosed in the Chinese authorization announcement number CN219206648U, the coffee grinder adopts the following nesting amount adjustment structure: an adjustment component for adjusting the nesting amount of the serving cup is provided between the serving cup and the grinding device; the adjustment component includes a stepped trough body and an adjustment convex part, the stepped trough body is provided on the grinding device, the adjustment convex part is provided on the serving cup, and the adjustment convex part is embedded in the stepped trough body. This coffee grinder adjusts the nesting amount by making the adjustment convex part abut against different positions of the stepped trough body. Since the adjustment convex part on the serving cup only abuts against the stepped trough body, the limiting effect between the serving cup and the grinding device in the vertical direction is weak. When holding this coffee grinder for grinding operation, it is necessary to hold the serving cup and the grinding device at the same time to prevent the serving cup from slipping off the grinding device. Since the diameter of this coffee grinder is not too large, when switching hands to hold this coffee grinder, it is necessary to make enough space for the hand holding the coffee grinder to be grasped by the other hand, and at the same time, both hands must be used to always restrain the serving cup and the grinding device together during this process. Otherwise, the serving cup may easily slip off. Therefore, it is inconvenient to switch hands to hold the coffee grinder, which easily affects the convenience of hand-held grinding.

[0004] Therefore, it is very necessary to redesign the structure of the coffee grinder. Utility Model Content

[0034] like Figures 1 to 4 As shown, a portable coffee grinding device described in the utility model includes a grinding cylinder 1 and a serving cup 2. The serving cup 2 is movably mounted on the discharge end 11 of the grinding cylinder 1. In order to achieve the inventive purpose of the utility model, a first positioning body 10 is arranged on the discharge end 11, and a second positioning body 20 is arranged on the cup body of the serving cup 2. The second positioning body 20 can produce a magnetic positioning effect with the first positioning body 10.

[0035] In the portable coffee grinding device, by setting the first positioning body 10 on the discharge end 11 and setting the second positioning body 20 on the serving cup 2, the second positioning body 20 can also produce a magnetic positioning effect with the first positioning body 10. When the second positioning body 20 produces a magnetic positioning effect with the first positioning body 10, the serving cup 2 can be stably limited in the material receiving state to prevent the serving cup 2 from sliding freely, which not only makes it more convenient to hold, but also greatly facilitates the exchange of holding hands, thereby greatly improving the convenience of hand-held grinding. In the portable coffee grinding device, positioning is achieved through the magnetic positioning effect, which can make it extremely convenient to adjust the nesting amount of the serving cup 2, which not only makes it very convenient to adjust the overall volume, but also can quickly and stably limit the serving cup and the grinding cylinder together. The portable coffee grinding device has the advantages of easy use, high reliability, and strong applicability. The containing cup 2 is movably mounted on the discharge end 11 of the grinding cylinder 1, so that the overall volume of the portable coffee grinding device can be reduced by completely mounting the cup cavity of the containing cup 2 on the discharge end 11, making it very convenient to store and carry.

[0036] In the actual manufacturing process, at least two second positioning bodies 20 can be arranged side by side in the height direction of the serving cup 2, and each second positioning body 20 can produce a magnetic positioning effect with the first positioning body 10. In this way, by making different second positioning bodies 20 produce a magnetic positioning effect with the first positioning body 10, it can be ensured that the serving cup 2 can be stably placed on the grinding cylinder 1 under various nesting amounts. Therefore, when grinding different amounts, the serving cup 2 can be adjusted to the corresponding serving amount, which can facilitate meeting the needs of grinding different amounts, especially facilitating the grinding of large volumes of coffee powder. The portable coffee grinding device can meet more usage needs, thereby helping to further improve the applicability of the portable coffee grinding device.

[0037] The first positioning body 10 is a magnetic positioning body, and the second positioning body 20 is a magnetic positioning body and / or an iron positioning body; or, the first positioning body 10 is an iron positioning body, and the second positioning body 20 is a magnetic positioning body. This can help the second positioning body 20 to produce a stable and reliable magnetic positioning effect with the first positioning body 10, thereby ensuring that the portable coffee grinding device has high reliability and applicability.

[0038] When the first positioning body 10 is an iron positioning body, the first positioning body 10 can be formed by making a certain part of the structure on the grinding cylinder 1 adopt an iron material. When the second positioning body 20 is an iron positioning body, the second positioning body 20 can be formed by making a certain part of the containing cup 2 adopt an iron material. This can also well meet the needs of actual use.

[0039] like Figure 3As shown, the bottom of the serving cup 2 is provided with a third positioning body 30, and the third positioning body 30 can produce a magnetic positioning effect with the first positioning body 10 and / or the discharge end 11. In this way, when the cup cavity of the serving cup 2 is completely covered with the discharge end 11, the serving cup 2 can be stably restricted by the magnetic positioning effect generated by the third positioning body 30 and the first positioning body 10, which can ensure that the assembly at this time is very stable, thereby helping to further improve the stability and convenience of storage and carrying.

[0040] When a magnetic positioning effect is generated between the third positioning body 30 and the first positioning body 10, and the first positioning body 10 adopts a magnetic positioning body, the third positioning body 30 is a magnetic positioning body and / or an iron positioning body; when the first positioning body 10 adopts an iron positioning body, the third positioning body 30 is a magnetic positioning body.

[0041] When the third positioning body 30 is made of iron, the third positioning body 30 can be formed by making a certain part of the serving cup 2 made of iron material, which can also meet the actual use requirements very well.

[0042] like Figures 3 to 5 As shown, the third positioning body 30 includes a plurality of third magnet blocks 301, each of which is embedded on the bottom surface of the serving cup 2, and a covering pad 302 is installed on the bottom surface of the serving cup 2 for covering each of the third magnet blocks 301. This not only facilitates the generation of a stable and reliable magnetic positioning effect, but also prevents the third magnet blocks 301 from being exposed to the outside, thereby making the overall structure more stable and coordinated.

[0043] like Figure 5 As shown, each third magnet block 301 is arranged around the vertical center line of the serving cup 2, which can help produce a more stable and reliable magnetic attraction, thereby helping to further improve the stability and convenience of storage and carrying.

[0044] The covering pad 302 is a silicone gasket bonded to the bottom surface of the serving cup 2. This not only controls the material, but also plays a good covering role, and can help to make the placement of the portable coffee grinding device more stable and reduce the noise during the placement process, which helps to further improve the applicability of the portable coffee grinding device.

[0045] like Fig.10 As shown, the grinding cylinder 1 includes an outer cylinder 13, a grinding core 14, and an adjuster 15 for adjusting the position of the grinding core 14. The grinding core 14 and the adjuster 15 are both arranged in the outer cylinder 13, and the third positioning body 30 can produce a magnetic positioning effect with the adjuster 15. This not only facilitates manufacturing, but also helps to produce a stable magnetic positioning effect, thereby helping to further improve the reliability and applicability of the portable coffee grinding device.

[0046] like Fig.10 As shown, the assembly structure of the outer cylinder 13, the grinding core 14 and the regulator 15 directly adopts the structure of the existing grinding cylinder 1, but the regulator 15 adopts a material that can generate magnetic force with the third positioning body 30, so as to meet the actual manufacturing and use requirements.

[0047] like Fig.10 and Fig.13 As shown, when the third positioning body 30 and the regulator 15 produce a magnetic positioning effect, the regulator 15 can be made of an iron block, and the third positioning body 30 can be made of a magnet block or multiple magnet blocks. In this way, the third positioning body 30 and the regulator 15 can produce a magnetic positioning effect, thereby meeting the actual manufacturing and use requirements.

[0048] like Fig.10 and Fig.13 As shown, when the third positioning body 30 is a magnet block, the third positioning body 30 is embedded in the middle of the bottom surface of the serving cup 2, and the third positioning body 30 is covered by a silicone pad 220 attached to the bottom surface of the serving cup 2. This not only helps to produce a stable and reliable magnetic positioning effect, but also prevents the third positioning body 30 from being exposed to the outside, so that the overall structure can be more stable and coordinated. The silicone pad 220 can not only help to make the placement of the portable coffee grinding device more stable, but also reduce the noise during the placement process, which helps to further improve the applicability of the portable coffee grinding device.

[0049] like Figures 2 to 8 As shown, the first positioning body 10 includes a plurality of first magnet blocks 101, each of which is arranged around the discharge end 11, and the magnetic poles of the outer ends of adjacent first magnet blocks 101 are different, and the second positioning body 20 includes a plurality of second magnet blocks 201, each of which is arranged around the cup cavity of the serving cup 2, and the magnetic poles of the inner ends of adjacent second magnet blocks 201 are different. Arranging the first magnet block 101 and the second magnet block 201 in this way can not only achieve the purpose of magnetic locking, but also generate repulsive force when the grinding cylinder 1 and the serving cup 2 are relatively rotated, thereby achieving a suspension effect, and the magnetic locking state can make objects below 2.5KG in a locked state. When the grinding cylinder 1 and the serving cup 2 are relatively rotated, so that the repulsive force is generated between the first magnet block 101 and the second magnet block 201, it is convenient to pull the serving cup 2 on the grinding cylinder 1, so that the needs of adjusting the position of the serving cup 2 and detaching the serving cup 2 can be met very conveniently. This not only facilitates stable and reliable magnetic positioning between the first positioning body 10 and the second positioning body 20, but also helps to further improve the convenience of using the portable coffee grinding device.

[0050] like Figure 7 and Figure 8As shown, the number of the first magnet blocks 101 is equal to the number of the second magnet blocks 201. When the first magnet blocks 101 and the second magnet blocks 201 are both odd numbers and arranged in a circular array, there will be a pair of adjacent first magnet blocks 101 with the same magnetic poles at the outer ends, and similarly, there will be a pair of adjacent second magnet blocks 201 with the same magnetic poles at the inner ends. This does not affect normal use, and its magnetic positioning function is still very stable and reliable.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, a positioning ring groove 111 is provided on the outer side of the discharge end 11, and the first magnet block 101 is an arc-shaped magnet matching the positioning ring groove 111. Each first magnet block 101 is embedded in the positioning ring groove 111. A clamping ring 12 is provided on the port of the discharge end 11, and the clamping ring 12 and the positioning ring groove 111 are used to clamp each first magnet block 101. This not only enables the portable coffee grinding device to have a compact structure, but also facilitates and stably limits the first magnet block 101 on the discharge end 11, thereby helping to improve the convenience and stability of assembly.

[0052] like Figure 3 , Figure 4 and Figure 6 As shown, one end of the first magnet block 101 away from the clamping ring 12 is embedded in the groove wall of the positioning ring groove 111, and the clamping ring 12 is clamped on the first magnet block 101. In this way, the first magnet block 101 can be more stably fixed on the discharge end 11, thereby helping to further improve the stability and reliability of the installation and positioning of the first magnet block 101, and further helping to further improve the reliability of the portable coffee grinding device.

[0053] like Figure 3 , Figure 4 and Figure 6 As shown, the clamping ring 12 is fixed to the discharge end 11 by at least one screw 121. This can meet the requirements of stable clamping, thereby meeting the requirements of actual manufacturing and use.

[0054] like Figure 3 , Figure 4 and Figure 6As shown, when the third positioning body 30 and the discharge end 11 produce a magnetic positioning effect, one or more components of the discharge end 11 can be used to form a structure that produces a magnetic positioning effect with the third positioning body 30, for example: the clamping ring 12 is used to form a structure on the discharge end 11 that produces a magnetic positioning effect with the third positioning body 30. At this time, the clamping ring 12 is an iron ring, and the third positioning body 30 is a magnetic positioning body. In this way, the magnetic positioning effect can be stably achieved, thereby ensuring that the portable coffee grinding device has a very strong reliability. In the actual manufacturing process, not only can the regulator 15 or the clamping ring 12 on the discharge end 11 be used to form a structure that produces a magnetic positioning effect with the third positioning body 30, but also the rotating shaft, grinding core, grinding ring, spring, limit stopper or screw on the discharge end 11 can be used to form a structure that produces a magnetic positioning effect with the third positioning body 30. Similarly, one or more components on the discharge end 11 can be used to form the first positioning body 10, which can also meet the needs of actual manufacturing and use.

[0055] like Figure 3 , Figure 4 and Figure 6 As shown, when the third positioning body 30 adopts a plurality of third magnet blocks 301, each third magnet block 301 is made to correspond to the clamping ring 12, so that a more stable and reliable magnetic positioning effect can be achieved, thereby helping to further improve the reliability and applicability of the portable coffee grinding device.

[0056] like Figures 3 to 5 As shown, the outer circumferential surface of the serving cup 2 is provided with a limiting annular groove 21, and the second magnet block 201 is an arc-shaped magnet matching the limiting annular groove 21. Each second magnet block 201 is embedded in the limiting annular groove 21, and the serving cup 2 is covered with a limiting sleeve 22, and the limiting sleeve 22 covers the limiting annular groove 21. This not only enables the portable coffee grinding device to have a compact structure, but also facilitates the second magnet block 201 to be stably limited on the serving cup 2, thereby helping to improve the convenience and stability of assembly. This also facilitates cleaning and maintenance, which helps to further improve applicability.

[0057] The limiting cover 22 is a leather cover, which not only improves the comfort of use, but also improves the quality, thereby helping to further improve the market competitiveness of the portable coffee grinding device.

[0058] like Figures 3 to 5As shown, the serving cup 2 is provided with a mounting ring groove 23, the limiting ring groove 21 is located at the bottom of the mounting ring groove 23, the limiting sleeve 22 is composed of leather embedded in the mounting ring groove 23, and the inner wall of the leather is bonded to the bottom of the mounting ring groove 23 by 3M double-sided tape or glue. In this way, the requirement of stable mounting of the limiting sleeve 22 can be conveniently achieved, thereby helping to further improve the stability and reliability of the mounting and positioning of the limiting sleeve 22.

[0059] like Figures 1 to 4 As shown, the grinding cylinder 1 is connected to a rotating drive mechanism 3, and a shock-absorbing washer 4 is sandwiched between the rotating drive mechanism 3 and the grinding cylinder 1. This can reduce vibration and noise, thereby helping to further improve the applicability of the portable coffee grinding device.

[0060] like Figures 1 to 4 As shown, the shock-absorbing gasket 4 is a silicone gasket, and the shock-absorbing gasket 4 is sleeved on the rotary drive mechanism 3 or the grinding cylinder 1. This can play a more stable and reliable role in shock absorption and noise reduction.

[0061] like Figure 3 and Figure 4 As shown, when in use, the grinding cylinder 1 and the serving cup 2 are pulled apart by a certain distance, and the first positioning body 10 and the second positioning body 20 produce a magnetic positioning effect, which can make the serving cup 2 stably placed on the grinding cylinder 1, so that it is convenient to stably receive the powder ground by the grinding cylinder 1. When the cup cavity of the serving cup 2 is completely fitted on the discharge end 11, the third positioning body 30 and the clamping ring 12 produce a magnetic positioning effect, which can ensure that the storage and carrying are very stable and convenient.

[0062] like Figures 9 to 11 As shown, the rotary sleeve on the grinding cylinder 1 is connected to a rotary drive mechanism 3 that is connected to the grinding cylinder 1, and at least one elastic anti-rotation component 5 is provided between the non-rotating working part of the grinding cylinder 1 and the non-rotating working part of the rotary drive mechanism 3 to prevent the rotation of the rotary sleeve connection. In this way, the grinding cylinder 1 and the rotary drive mechanism 3 can be conveniently and accurately docked together, thereby helping to improve the convenience and stability of docking.

[0063] like Figures 1 to 4 , Fig. 9 and Fig.10 As shown, the rotary drive mechanism 3 is an electric drive mechanism or a manual drive mechanism. The electric drive mechanism can facilitate grinding, thereby improving the convenience of grinding. The manual drive mechanism can reduce the use cost.

[0064] The above-mentioned rotary sleeve connection can adopt both threaded rotary sleeve connection and Figures 9 to 12 The rotating sleeve structure shown can meet the needs of actual use very well.

[0065] like Figures 9 to 12 As shown, the rotation drive mechanism 3 is provided with a mounting hole 31, the elastic anti-rotation assembly 5 includes a spring 51 and an anti-rotation ball 52, the spring 51 and the anti-rotation ball 52 are arranged in the mounting hole 31, and the anti-rotation ball 52 is partially protruded out of the mounting hole 31 under the elastic action of the spring 51, and the grinding cylinder 1 is provided with a positioning groove 16, and the part of the anti-rotation ball 52 protruding from the mounting hole 31 is embedded in the positioning groove 16. Such an elastic anti-rotation assembly 5 is very reliable, which not only has a good anti-rotation effect, but also is convenient for users to disassemble and assemble, thereby ensuring that it is very convenient to use.

[0066] like Fig.10 and Fig.11 As shown, the rotary drive mechanism 3 is embedded with a positioning cylinder 32 with a closed inner end, and the inner hole of the positioning cylinder 32 constitutes a mounting hole 31, and the hole diameter of the mounting hole 31 is smaller than the diameter of the anti-rotation ball 52. In this way, during manufacturing, the spring 51 and the anti-rotation ball 52 can be installed in the positioning cylinder 32 first, and then the positioning cylinder 32 can be embedded in the rotary drive mechanism 3, which can help reduce the difficulty of assembly and ensure that the elastic anti-rotation component 5 has a very high reliability.

[0067] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
