Description

Technical Field

[0001] This utility model relates to the field of coffee brewing equipment, and in particular to a coffee powder dispenser. Background Technology

[0002] Before brewing, the ground coffee needs to be leveled and tamped in the portafilter, a process usually accomplished using a distributor and tamper. The distributor breaks up clumps and distributes the coffee grounds evenly to prevent channeling during extraction and improve coffee quality.

[0003] Currently, there is a type of active coffee grounds dispenser on the market, which has a rotating disc with multiple stirring needles inside. By rotating the dispenser handle, the user drives the disc to rotate in the coffee grounds, effectively breaking up clumps and achieving even distribution of coffee grounds.

[0004] However, existing rotary disc coffee dispensers often have structural flaws. The most common design uses a simple shaft and bushing connection to rotate the disc. This sliding friction method results in significant resistance, leading to a stiff and unsmooth rotation and a poor user experience. With prolonged use, wear on the friction points can cause the disc to wobble or even seize, affecting product lifespan and reliability. Furthermore, many designs lack sufficient consideration for axial positioning of the disc. During operation, the disc may accidentally detach from the outer ring due to gravity or vibration, affecting normal use and potentially causing coffee powder spillage. Utility Model Content

[0044] Reference Figures 1-7 The basic embodiment of the first aspect of this utility model provides a coffee powder dispenser, comprising:

[0045] Outer ring 100;

[0046] Needle plate 200 is located within outer ring 100;

[0047] The outer ring 100 and the needle plate 200 have a first annular groove 210 on one wall and a ball bearing 300 on the other wall. The ball bearing 300 can slide in the first annular groove 210, so that the outer ring 100 and the needle plate 200 can rotate relative to each other.

[0048] According to embodiments of this utility model, the following effects can be achieved through this configuration: the needle disc 200 is equipped with several stirring needles, which can efficiently break up coffee powder clumps and achieve uniform powder distribution. By placing the needle disc 200 inside the outer ring 100, it has a rotation function, thereby achieving thorough stirring of the coffee powder during operation. The mating structure of the first annular groove 210 and the ball bearing 300 significantly improves the smoothness and stability of their relative rotation, making the rotation action smoother and less strenuous. At the same time, this structure also has an axial limiting function. When the ball bearing 300 is embedded in the first annular groove 210, it can effectively limit the vertical displacement of the needle disc 200, preventing it from detaching from the outer ring 100 and ensuring reliability and safety during use. In addition, this rolling friction method also reduces wear, extends the service life of components, and the overall structure is compact and reasonable, suitable for high-frequency rotation operation scenarios.

[0049] It should be noted that the ball bearing 300 and the first annular groove 210 can be respectively disposed on the outer ring 100 and the needle plate 200. The positions of the ball bearing 300 and the first annular groove 210 can be interchanged, and their functions remain the same. The first annular groove 210 disposed on the needle plate 200 and the ball bearing 300 disposed on the outer ring 100 in the attached figure is one embodiment.

[0050] In some embodiments, in the first embodiment, a first annular groove 210 is provided on the needle plate 200, and a second annular groove 110 is provided on the outer ring 100. Multiple balls 300 are provided, and the multiple balls 300 are disposed in the annular cavity between the first annular groove 210 and the second annular groove 110, allowing the outer ring 100 and the needle plate 200 to rotate relative to each other. The multiple balls 300, in conjunction with the double annular groove structure, constitute a simple yet efficient rolling support system, significantly reducing rotational friction resistance, improving operational smoothness and feel stability, while also helping to evenly distribute the load and extend service life.

[0051] In some embodiments, the outer ring 100 is provided with a feed inlet that communicates with the annular inner cavity. The ball bearing 300 can enter or exit the annular inner cavity through the feed inlet. The feed inlet is provided with a detachable sealing member 400 for closing the feed inlet. The sealing member 400 can effectively prevent the ball bearing 300 from falling off due to vibration during transportation or use, ensuring the durability and reliability of the structure and safe use.

[0052] In some embodiments, specifically the second embodiment, a first annular groove 210 is provided on the needle plate 200, and an outer ring 100 is provided with a ball positioning groove 120. The number of balls 300 and ball positioning grooves 120 corresponds, and multiple balls 300 are provided. The radially outer end of each ball 300 is located within the ball positioning groove 120, and the radially inner end of each ball 300 is located within the first annular groove 210. This structure ensures smooth rotation while simplifying the manufacturing process, which helps control costs and improve assembly reliability.

[0053] In some embodiments, the outer ring 100 is provided with a feed inlet, which communicates with the ball positioning groove 120. The feed inlet is provided with a detachable sealing member 400, which is used to close the feed inlet and whose radially inner end can abut against the ball 300. The sealing member 400 can effectively prevent the ball 300 from falling off due to vibration during transportation or use, ensuring the durability and reliability of the structure and safe use.

[0054] It should be noted that the position of the feed inlet on the outer ring 100 and the needle plate 200 depends on the position of the first annular groove 210. As shown in the attached figure, if the first annular groove 210 is located on the needle plate 200, then the feed inlet is located on the outer ring 100.

[0055] In some embodiments, the sealing element 400 is a screw, pin, or clip connected to the feed inlet. The sealing element 400 serves a sealing function, wherein a screw threaded connection, a pin directly inserted, or a clip engaging the feed inlet can all block the feed inlet.

[0056] In some embodiments, a powder receiving ring 230 is also included, which is disposed on the chuck 200. The powder receiving ring is used to collect coffee powder, which can enter the chuck 200 from the powder receiving ring.

[0057] In some embodiments, the needle plate 200 includes a powder application assembly 240. The needle plate 200 is rotatably mounted on the outer ring 100. The inner wall of the needle plate 200 has a mounting groove, within which the powder application assembly 240 is disposed. A powder receiving ring 230 is disposed on the mounting groove, and the powder receiving ring 230 restricts the movement of the powder application assembly 240. The needle plate 200 is mounted on the outer ring 100, and the powder application assembly 240 is mounted within the mounting groove of the needle plate 200. The limiting effect of the powder receiving ring 230 confines the powder application assembly 240 within the needle plate 200, facilitating installation and use. This modular structure not only facilitates assembly and maintenance but also allows for the replacement of the powder application assembly 240 to meet different powder application needs, enhancing the product's adaptability and practicality.

[0058] In some embodiments, the inner diameter of the receiving ring 230 gradually decreases from top to bottom. This continuous change in the inner diameter of the receiving ring 230 facilitates coffee powder feeding. This funnel-shaped design helps guide coffee powder smoothly into the portafilter 500, reducing residue and clogging, and further optimizing the uniformity of coffee powder distribution.

[0059] In some embodiments, a coffee dispenser 500 is also included, with an outer ring 100 or a needle plate 200 detachably disposed on the coffee dispenser 500. The coffee dispenser 500 is used to hold coffee powder. This design allows the dispenser to be adapted to various sizes of coffee dispensers 500, increasing flexibility of use and facilitating cleaning and storage.

[0060] In some embodiments, one or more of the portafilter 500 and outer ring 100 are equipped with magnetic elements, and the portafilter 500 and outer ring 100 are magnetically connected. A magnet is added to the bottom to attract the metal portafilter 500, preventing it from easily falling off. When loading coffee powder, the coffee powder falls directly onto the needle plate 200, passes through the beveled needle plate, and falls onto the portafilter 500. Rotating the powder receiving ring 230 by hand drives the inner ring, which in turn drives the needle plate, achieving even powder distribution. This magnetic connection method not only facilitates installation and removal but also provides sufficient connection stability during powder distribution, preventing the portafilter 500 from accidentally falling off due to operational vibrations, and is especially suitable for metal portafilters 500.

[0061] In some embodiments, the outer ring 100 is provided with a retaining foot 140 and also includes a coffee handle. The coffee handle has a retaining groove, and the retaining groove and the retaining foot 140 can cooperate to allow the outer ring 100 to be installed on the coffee handle. This product has both a coffee powder receiving function and a coffee powder dispensing function, allowing the coffee powder dispenser to be placed on the coffee handle to receive coffee powder from the grinder.

[0062] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0063] Although some embodiments of the present utility model have been shown and described in this specification, the present utility model should not be limited to the above embodiments. As long as they achieve the technical effects of the present utility model by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles disclosed in the present utility model, without departing from the principles and purpose of the present utility model, should be included within the scope of protection disclosed in the present utility model and should be considered to fall within the protection scope of the present utility model.
