Description

Technical Field

[0001] This utility model relates to the technical field of coffee, and in particular to a rotating powder distribution structure and a coffee powder distributor. Background Technology

[0002] In recent years, with the continuous improvement of people's living standards, their enthusiasm for coffee culture has also increased. However, making a cup of coffee requires several processing steps for the coffee grounds. Among these, tamping and distributing the coffee grounds are particularly important. In response, some businesses have developed coffee grounds distributors specifically designed for this purpose.

[0003] For example, Chinese patent document CN221153790U discloses a gravity-adjustable powder distributor, including a fixed top cover and a support base. A gravity powder distribution unit is threadedly connected to the bottom of the fixed top cover, a bearing is fixedly installed on the top of the support base, and a connecting unit is snapped into the top of the support base. An adjustment unit is threadedly connected to the upper end of the connecting unit. Through the cooperation of the adjustment unit and the connecting unit, the height of the powder distributor can be adjusted.

[0004] However, although the gravity-adjustable powder dispenser mentioned above can adjust the height of the powder dispenser through the cooperation of the adjustment unit and the connection unit, when the powder dispenser is pressed down, it cannot work with the fixed top cover to rotate and stir the coffee powder, which makes it impossible to stir some firm coffee powder evenly. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotating powder distribution structure and a coffee powder distributor that can rotate and compact coffee powder.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A rotating powder-dispensing structure includes an upper cover, a fixed base, a connecting rod, and a powder-dispensing base. The upper cover has a sliding cavity, the fixed base is slidably disposed on the peripheral wall of the sliding cavity, and the powder-dispensing base abuts against the fixed base on the side away from the upper cover. The fixed base has a rotating cavity that communicates with the sliding cavity. A first end of the connecting rod is fixedly connected to the side of the upper cover near the fixed base, and a second end of the connecting rod passes through the sliding cavity and the rotating cavity and is connected to the powder-dispensing base.

[0008] In one embodiment, the top cover has a first screw hole on the side near the fixed base, the powder base has a second screw hole on the side near the fixed base, the first end of the connecting rod is threaded to the first screw hole, and the second end of the connecting rod passes through the sliding cavity and the rotating cavity in sequence and is threaded to the second screw hole.

[0009] In one embodiment, the rotating powder distribution structure further includes a ball bearing, and the mounting base has an installation cavity on the side near the top cover, in which the ball bearing is embedded.

[0010] In one embodiment, the rotating powder distribution structure further includes a first bearing and a second bearing. A first mounting groove and a second mounting groove are formed on the inner wall of the rotating cavity. A limiting boss is protruding from the inner peripheral wall of the rotating cavity, and the limiting boss has a through hole. The first mounting groove is connected to the second mounting groove through the through hole. The outer ring of the first bearing is embedded in the first mounting groove, and the inner ring of the first bearing is sleeved on the connecting rod. The outer ring of the second bearing is embedded in the second mounting groove, and the inner ring of the second bearing is sleeved on the connecting rod.

[0011] In one embodiment, there are multiple balls and multiple mounting cavities, with each ball corresponding to one mounting cavity.

[0012] In one embodiment, the connecting rod and the fixing seat are integrally formed.

[0013] In one embodiment, the fixing seat has a receiving cavity on the side away from the upper cover, and the powder base is disposed in the receiving cavity and fixedly connected to the second end of the connecting rod.

[0014] In one embodiment, the peripheral wall of the accommodating cavity is provided with an annular boss, which abuts against the side of the powder base near the fixing seat.

[0015] In one embodiment, the rotating powder distribution structure further includes several magnets, and the outer periphery of the powder distribution base away from the fixed base is provided with several adsorption holes, with each magnet correspondingly disposed in each adsorption hole.

[0016] A coffee powder dispenser includes the rotating powder dispensing structure described in any of the above embodiments.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] Because the top cover has a sliding cavity, and the fixing seat is slidably mounted on the inner wall of the sliding cavity, the fixing seat can slide up and down within the sliding cavity. Since the powder distribution base abuts against the side of the fixing seat away from the top cover, and the first end of the connecting rod is fixedly connected to the top cover, while the second end of the connecting rod passes through the sliding cavity and connects to the powder distribution base, when the top cover is pressed, the fixing seat slides within the sliding cavity, causing the top cover to move downwards relative to the peripheral wall of the fixing seat. This applies pressure to the powder distribution base, allowing it to press against the coffee portafilter. Simultaneously, the first end of the connecting rod passes through the sliding cavity and the rotating cavity and connects to the powder distribution base, allowing the connecting rod to rotate within the rotating cavity. Since both ends of the connecting rod are fixed to the top cover and the powder distribution base, rotating the top cover causes the powder distribution base to rotate as well. When the rotating powder distribution structure is installed in the portafilter, the top cover can drive the powder distribution base to rotate, thereby stirring the coffee powder in the portafilter. At the same time, during the stirring process, the top cover can slide downward relative to the outer peripheral wall of the fixed base, thereby applying pressure to the powder distribution base, so that the powder distribution base compacts the coffee powder in the portafilter.

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 3 An implemented rotating powder application structure 10 includes an upper cover 100, a fixing seat 200, a connecting rod 300, and a powder application base 400. The upper cover 100 has a sliding cavity 110, the fixing seat 200 is slidably disposed on the peripheral wall of the sliding cavity 110, and the powder application base 400 abuts against the side of the fixing seat 200 away from the upper cover 100. The fixing seat 200 has a rotating cavity 210, which communicates with the sliding cavity 110. The first end of the connecting rod 300 is fixedly connected to the side of the upper cover 100 near the fixing seat 200, and the second end of the connecting rod 300 passes through the sliding cavity 110 and the rotating cavity 210 and is connected to the powder application base 400.

[0028] In this embodiment, because the upper cover 100 has a sliding cavity 110, and the fixing seat 200 is slidably disposed on the inner wall of the sliding cavity 110, the fixing seat 200 can slide up and down in the sliding cavity 110. Because the powder distribution base 400 abuts against the side of the fixing seat 200 away from the upper cover 100, and the first end of the connecting rod 300 is fixedly connected to the upper cover 100, and the second end of the connecting rod 300 passes through the sliding cavity 110 and is connected to the powder distribution base 400, when the upper cover 100 is pressed, because the fixing seat 200 slides in the sliding cavity 110, the upper cover 100 can apply pressure to the powder distribution base 400 when it moves downward relative to the peripheral wall of the fixing seat 200, thereby enabling the powder distribution base 400 to press the pressure of the coffee handle. Meanwhile, the first end of the connecting rod 300 passes through the sliding cavity 110 and the rotating cavity 210 and is connected to the powder distribution base 400, allowing the connecting rod 300 to rotate within the rotating cavity 210. Since both ends of the connecting rod 300 are fixed to the upper cover 100 and the powder distribution base 400, the upper cover 100 can rotate, thus driving the powder distribution base 400 to rotate as well. When the rotating powder distribution structure 10 is installed in the coffee portafilter, the upper cover 100 can drive the powder distribution base 400 to rotate, thereby stirring the coffee powder in the portafilter. Simultaneously, during the stirring process, the upper cover 100 can slide downwards relative to the outer peripheral wall of the fixed base 200, applying pressure to the powder distribution base 400 and compacting the coffee powder in the portafilter.

[0029] Please see Figure 2 In one embodiment, the upper cover 100 has a first threaded hole 120 on the side near the fixed base 200, and the powder distribution base 400 has a second threaded hole 410 on the side near the fixed base 200. The first end of the connecting rod 300 is threaded to the first threaded hole 120, and the second end of the connecting rod 300 passes through the sliding cavity 110 and the rotating cavity 210 in sequence and is threaded to the second threaded hole 410. It can be understood that the presence of a first threaded hole 120 on one side of the upper cover 100 and a second threaded hole 410 on one side of the powder distribution base 400 allows the first end of the connecting rod 300 to be threaded to the first threaded hole 120, and the second end of the connecting rod 300 to be threaded to the second threaded hole 410, thereby connecting both ends of the connecting rod 300 to the upper cover 100 and the powder distribution base 400.

[0030] Please see Figure 2 and Figure 3In one embodiment, the rotating powder distribution structure further includes ball bearings 500. The mounting base 200 has a mounting cavity 220 on the side near the upper cover 100, and the ball bearings 500 are embedded in the mounting cavity 220. It is understood that by providing the mounting cavity 220 on the side of the mounting base 200 near the upper cover 100, and by adhesively embedding the ball bearings 500 within the mounting cavity 220, when the upper cover 100 slides downwards to a level abutting against the mounting base 200, the ball bearings 500 located in the mounting base 200 will contact the upper cover 100. This reduces frictional wear between the upper cover 100 and the mounting base 200 during rotation.

[0031] Please see Figure 2 In one embodiment, the rotating powder distribution structure further includes a first bearing 600 and a second bearing 700. A first mounting groove 2120 and a second mounting groove 2130 are formed on the inner wall of the rotating cavity 210. A limiting boss 2110 is protruding from the inner peripheral wall of the rotating cavity 210. The limiting boss 2110 has a through hole. The first mounting groove 2120 is connected to the second mounting groove 2130 through the through hole. The outer ring of the first bearing 600 is embedded in the first mounting groove 2120, and the inner ring of the first bearing 600 is sleeved on the connecting rod 300. The outer ring of the second bearing 700 is embedded in the second mounting groove 2130, and the inner ring of the second bearing 700 is sleeved on the connecting rod 300, so that the connecting rod 300 is reliably rotatably connected in the rotating cavity. Furthermore, the first bearing component 600 and the second bearing component 700 are sleeved on the body of the connecting rod 300. Using the first bearing component 600 and the second bearing component 700, the connecting rod 300 can rotate more stably within the rotating cavity 210.

[0032] Please see Figure 2 Furthermore, both the number of the ball bearings 500 and the number of the mounting cavities 220 are multiple, with each ball bearing 500 correspondingly disposed within one mounting cavity 220. It is understood that by providing multiple mounting cavities 220 in the fixed base 200, and with each ball bearing 500 correspondingly disposed within one mounting cavity 220, when the fixed base 200 rubs against the upper cover 100, the multiple balls bearings 500 work together to more stably rotate the upper cover 100, further reducing frictional wear and extending the service life of the component. The multiple balls bearings 500 can be evenly distributed circumferentially along the side of the fixed base 200 near the upper cover 100 to ensure balanced force distribution when the upper cover 100 rotates, avoiding jamming or uneven wear caused by excessive local friction, and improving the overall structural stability.

[0033] See Figure 3In one embodiment, the connecting rod 300 and the fixing seat 200 are integrally formed. It is understood that by designing the connecting rod 300 and the fixing seat 200 as an integrally formed structure, the stability and reliability of the overall structure can be further optimized. Specifically, integral forming avoids the assembly process between the connecting rod 300 and the fixing seat 200 and eliminates potential connection gaps, making them a more rigid whole. This effectively reduces connection loosening caused by long-term rotation or pressing operations and improves the fatigue resistance of the structure.

[0034] Please see Figure 1 and Figure 2 In one embodiment, the fixing base 200 has a receiving cavity 230 on the side away from the upper cover 100, and the powder distribution base 400 is disposed in the receiving cavity 230 and fixedly connected to the second end of the connecting rod 300. It can be understood that by providing a receiving cavity 230 on the side of the fixing base 200 away from the upper cover 100 and placing the powder distribution base 400 within it, radial limiting and protection of the powder distribution base 400 can be achieved. Specifically, the peripheral wall of the receiving cavity 230 can limit the radial swaying of the powder distribution base 400 during rotation or pressing, ensuring that the rotation axis of the powder distribution base 400 is consistent with the central axis of the fixing base 200, thereby ensuring a stable stirring trajectory of the coffee powder by the powder distribution base 400 and improving the uniformity of powder distribution.

[0035] See Figure 2 Furthermore, the accommodating cavity 230 has a protruding annular boss 2310 on its peripheral wall, which abuts against the side of the powder base 400 near the fixing seat 200. It can be understood that by providing the annular boss 2310 on the peripheral wall of the accommodating cavity 230, and with the annular boss 2310 abutting against the side of the powder base 400 near the fixing seat 200, the powder base 400 can be axially limited. Specifically, when the powder base 400 is pressed downwards with the upper cover 100, the annular boss 2310 can prevent the powder base 400 from moving excessively towards the fixing seat 200, avoiding excessive compression or collision between the powder base 400 and the internal structure of the fixing seat 200, thus protecting the powder base 400 and related components.

[0036] See Figure 2 and Figure 3In one embodiment, the rotating powder distribution structure further includes several magnets 800. The outer periphery of the powder distribution base 400, away from the fixing base 200, has several adsorption holes 420, with each magnet 800 corresponding to one adsorption hole 420. It is understood that having several adsorption holes 420 on the outer periphery of the powder distribution base 400 away from the fixing base 200, and each magnet 800 corresponding to one adsorption hole 420, allows the powder distribution base 400 to achieve stable magnetic adsorption positioning with the coffee handle. Specifically, the part of the coffee handle (usually made of metal, such as stainless steel) near the powder distribution base 400 can generate a magnetic attraction with the magnets 800. This attraction allows the powder distribution base 400 to quickly align and adhere to the coffee handle upon contact.

[0037] It should be noted that the coffee portafilter is a common tool in existing technology and coffee making, and will not be discussed in detail here.

[0038] This application also provides a coffee powder dispenser, including the rotating powder dispensing structure 10 described in any of the above embodiments. It is understood that the upper cover 100 drives the powder dispensing base 400 to rotate, thereby stirring the coffee powder in the portafilter. Simultaneously, during the stirring process, the upper cover 100 can slide downwards relative to the outer peripheral wall of the fixed base 200, thereby applying pressure to the powder dispensing base 400, causing the powder dispensing base 400 to compact the coffee powder in the portafilter.

[0039] Compared with the prior art, the present invention has at least the following advantages:

[0040] Because the top cover 100 has a sliding cavity 110, and the fixing seat 200 is slidably disposed on the inner wall of the sliding cavity 110, the fixing seat 200 can slide up and down in the sliding cavity 110. Because the powder distribution base 400 abuts against the side of the fixing seat 200 away from the top cover 100, and the first end of the connecting rod 300 is fixedly connected to the top cover 100, and the second end of the connecting rod 300 passes through the sliding cavity 110 and is connected to the powder distribution base 400, when the top cover 100 is pressed, because the fixing seat 200 slides in the sliding cavity 110, the top cover 100 moves downward relative to the peripheral wall of the fixing seat 200, and can apply pressure to the powder distribution base 400, so that the powder distribution base 400 can press the pressure of the coffee handle. Meanwhile, the first end of the connecting rod 300 passes through the sliding cavity 110 and the rotating cavity 210 and is connected to the powder distribution base 400, allowing the connecting rod 300 to rotate within the rotating cavity 210. Since both ends of the connecting rod 300 are fixed to the upper cover 100 and the powder distribution base 400, the upper cover 100 can rotate, thus driving the powder distribution base 400 to rotate as well. When the rotating powder distribution structure 10 is installed in the coffee portafilter, the upper cover 100 can drive the powder distribution base 400 to rotate, thereby stirring the coffee powder in the portafilter. Simultaneously, during the stirring process, the upper cover 100 can slide downwards relative to the outer peripheral wall of the fixed base 200, applying pressure to the powder distribution base 400 and compacting the coffee powder in the portafilter.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
