Description

TECHNICAL FIELD

[0001] The utility model is applied to the technical field of cloth powder needle, and particularly relates to an electric cloth powder device self-adaptive cloth powder needle structure. BACKGROUND

[0002] In the field of coffee making, various different coffee devices or instruments, such as coffee machines, bean grinders, extraction handles, etc., are used. After the grinding of coffee beans is completed, the coffee powder is concentrated on the powder bowl of the extraction handle. Since the initial state of the coffee powder is in a poor fluffy state, direct extraction will affect the taste of the coffee. Therefore, the coffee powder needs to be spread, so that the coffee powder can be evenly arranged in the powder bowl. At present, the coffee powder is mainly spread by a traditional cloth powder device. The operator needs to place the cloth powder device on the upper end of the powder bowl, and then manually rotates the cloth powder device to make a plurality of powder needles contact the coffee powder, so that the coffee powder can be more evenly distributed on the powder bowl. Since the coffee powder will accumulate on one side of the powder bowl during the powder taking process, the coffee powder will overflow or fall during the powder spreading. Therefore, a new type of electric cloth powder device gradually replaces the traditional cloth powder device. The electric cloth powder device can vibrate synchronously during powder taking to prevent the coffee powder from accumulating on one side, and can automatically rotate the coffee powder. After the powder taking is completed, the powder spreading operation can be realized. Since different types of coffee have different making methods, some coffee needs a powder bowl with a large diameter for extraction, and some coffee needs a powder bowl with a shallow depth for extraction. The current electric cloth powder device is single, and the powder needle cannot be adapted to powder bowls of different sizes. When powder spreading operation of powder bowls with different depths is needed, a plurality of powder needle assemblies need to be prepared for replacement, which is high in cost and low in replacement efficiency. If an electric cloth powder device self-adaptive cloth powder needle structure with simple structure, modular quick release design and self-adaptive adjustment of powder needle height according to the depth of the powder bowl can be designed, the above problems can be solved.

[0018] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a rotating ring 1 and a powder needle module 2. The powder needle module 2 includes a connecting ring 3, a powder distribution frame 4, and several floating powder needles 5. The powder distribution frame 4 is connected to the inner side of the rotating ring 1 through the connecting ring 3. The floating powder needles 5 include a sleeve 51, a needle sleeve 52, and powder needles 53. The powder needles 53 slide against the inner wall of the sleeve 51 through the needle sleeve 52. The rotating ring 1 drives several powder needles 53 to engage with the inner wall of the outer powder bowl. Therefore, when the powder needles 53 and the needle sleeve 52 are combined, and the powder needles 53 contact the bottom of the outer powder bowl, further pressing down on the sleeve 51 and the needle sleeve 52 allows for relative sliding, thereby achieving independent adaptive adjustment of several sets of powder needles 53.

[0019] like Figures 4 to 6 As shown, in this embodiment, a sliding channel 54 is provided in the middle of the upper end of the sleeve 51. The needle sleeve 52 slides in conjunction with the sliding channel 54. The powder needle 53 is connected to the lower end of the needle sleeve 52. The powder needle 53 cooperates with the powder needle clearance hole 55 at the lower end of the sleeve 51. The inner wall of the outer portafilter drives the powder needle 53 and the needle sleeve 52 to cooperate with the sleeve 51. Therefore, the needle sleeve 52 and the sliding channel 54 are adapted to each other, allowing the powder needle to slide. The powder needle clearance hole 55, adapted to the powder needle 53, prevents coffee powder from entering the sleeve 51 and causing blockage.

[0020] like Figures 1 to 3 As shown, in this embodiment, the outer side of the rotating ring 1 is configured as an arc surface, and the outer arc surface of the rotating ring 1 cooperates with the sliding end of the external rotating device. Therefore, the rotating ring 1 cooperates with the electric assembly of the external powder distributor to achieve rotation.

[0021] like Figures 1 to 3 As shown, in this embodiment, a plurality of teeth 6 are provided on the upper end of the outer arc surface of the rotating ring 1, and the teeth 6 are rotatably engaged with the rotating end of the motor of the external rotating device. Thus, the plurality of teeth 6 enable the rotating ring 1 to rotate on the electric assembly of the external powder distributor, and control the opening and stopping of the rotating ring 1.

[0022] like Figure 3 As shown, in this embodiment, the powder distribution frame 4 includes a support column 41 and a plurality of support rods 42. One end of each support rod 42 is disposed on the outer side of the support rod 42, and the support column 41 is connected to the inner side of the connecting ring 3 through the plurality of support rods 42. Thus, the plurality of support rods 42 are configured as arc-shaped rod structures, radiating outwards from the support column 41 and connected to the inner wall of the connecting ring 3.

[0023] As Figure 3 shown in the embodiment, the upper end of each support rod 42 is provided with an anti-piling protrusion 7, and the lower end surface of each support rod 42 is uniformly provided with a sleeve 51. As can be seen, the anti-piling protrusion 7 can effectively prevent coffee powder from piling up on the powder distribution frame 4 during powder taking.

[0024] As Figure 3 shown in the embodiment, the outer side of the connecting ring 3 is provided with a plurality of elastic buckles 8, and the inner side of the rotating ring 1 is provided with a plurality of limiting grooves 9, and the plurality of elastic buckles 8 are limited and matched with the plurality of limiting grooves 9. As can be seen, the plurality of elastic buckles 8 and the plurality of limiting grooves 9 can be quickly disassembled, and when different diameter powder bowls are used for extraction, the powder needle module 2 is pulled out upward, which can realize quick replacement, so as to adjust the density and range of the powder needle, and the applicability is strong.

[0025] The working principle of the utility model: before the equipment starts, the rotating ring 1 is connected with the external powder distributor electric component, the powder needle module 2 is buckled into the inner side of the rotating ring 1, the external powder distributor is placed vertically on the upper end of the powder bowl, and the plurality of powder needles 53 extend into the bottom of the powder bowl, when the powder needle 53 contacts the bottom of the powder bowl, the sleeve 51 and the needle sleeve 52 will slide relatively, when the external powder distributor is accurately placed on the upper end of the powder bowl, the plurality of needle sleeves 52 will adaptively adjust the relative position with the sleeve 51 according to the height of the bottom of the powder bowl, so as to achieve the independent adaptive depth adjustment of the plurality of powder needles 53, and the external powder distributor can be started to carry out powder distribution operation.

[0026] Although the embodiments of the utility model are described in actual schemes, but do not constitute the limitation to the meaning of the utility model, for the person skilled in the art, according to the modification of its implementation scheme and the combination with other schemes, it is obvious.
