[0027] Below, in conjunction with Figures 1 to 6 The present invention will be further described in the preferred embodiments and other embodiments. It should be noted that, without conflict, the technical features described below can be arbitrarily combined to form new embodiments.

[0028] Reference Appendix Figures 1-5 In a preferred embodiment, the present invention provides a beverage device, including a powder dispenser 10 and a drive mechanism 20. The powder dispenser 10 is used to distribute coffee powder onto an extraction container for extraction. The powder dispenser 10 includes a receiving cavity 3 and a rotating shaft L arranged in a vertical direction. The receiving cavity 3 includes a first section 4 and a second section 5. The first section 4 includes a powder inlet 41 at its upper end and a first powder outlet 42 at its lower end. The rotating shaft L passes through both the powder inlet 41 and the first powder outlet 42. The cross-section of the first section 4 gradually decreases from the powder inlet 41 toward the first powder outlet 42. The second section 5 is connected to the first... The powder outlet 42, the second section 5 is provided with a dividing rib 6, the dividing rib 6 divides the second section 5 into at least two powder feeding channels 51, and each powder feeding channel 51 is provided with a second powder outlet 53. The second section 5 includes a junction 52, the junction 52 is located below the first powder outlet 42, each powder feeding channel 51 includes a branching section 511, all of the branching sections 511 converge at the junction 52, each branching section 511 extends downward from the junction 52 in a direction away from the rotation axis L and connects to its corresponding second powder outlet 53, and the outer periphery of the powder distributor 10 is provided with gear teeth 10c. The drive wheel of the drive mechanism 20 meshes with the gear teeth 10c to drive the powder distributor 10 to rotate along the rotating shaft L. By setting the cross-section of the first section 4 to gradually decrease from the powder inlet 41 toward the first powder outlet 42, the powder distributor 10 of this invention can gradually gather as the coffee powder flows down from the powder inlet 41 to the first powder outlet 42 in the first section 4 during the process of distributing coffee powder to the extraction container. This allows the coffee powder to have sufficient gravity to overcome static electricity and fall off, preventing the coffee powder from adhering to the first section 4 and forming an accumulation. In addition, since the first powder outlet 42 is the part with the smallest aperture of the first section 4, by setting the intersection 52 below the first powder outlet 42, the separation rib 6 located at the first powder outlet 42 is prevented from causing coffee powder blockage.

[0029] Reference Appendix Figure 4In a preferred embodiment, each of the flow-diverting sections 511 of the powder dispenser 10 of this invention has a first side surface 61 formed by the dividing ribs 6. The first side surfaces 61 of all the flow-diverting sections 511 intersect at the junction 52, so that the top of the dividing ribs 6 forms a sharp angle. When the powder dispenser 10 of this invention is performing the powder dispensing operation, the coffee powder is prevented from accumulating on the top of the dividing ribs 6 during the process of entering the junction 52 from the first section 4, so as to avoid clogging. In this embodiment, the dividing ribs 6 are located below the first powder outlet 42 to prevent the coffee powder from accumulating at the first powder outlet 42.

[0030] Reference Appendix Figure 4 In a preferred embodiment, the powder inlet 41 and the first powder outlet 42 of the powder distributor 10 of this utility model are centrally located along the rotation axis L.

[0031] Reference Appendix Figure 4 In a preferred embodiment, each of the powder feeding channels 51 of the powder distributor 10 of this utility model further includes a vertical section 512 arranged vertically in the up-down direction. The vertical section 512 extends from the lower end of the diversion section 511 to its corresponding second powder outlet 53. Since coffee powder is relatively light, it is easy to adhere to the powder feeding channel 51. By setting the vertical section 512, the adhesion of coffee powder to the powder feeding channel 51 is reduced, thus avoiding blockage.

[0032] Reference Appendix Figure 3 and Figure 4 In a preferred embodiment, the device includes a main body 1 and a powder pressing part 2 protruding downward from the main body 1. The receiving cavity 3 extends from the main body 1 to the powder pressing part 2. The second powder outlet 53 is opened on the bottom wall of the powder pressing part 2. The bottom wall of the powder pressing part 2 is provided with a powder scraping part 21. The powder scraping part 21 extends from the rotating shaft L to the edge of the bottom wall of the powder pressing part 2. The powder scraping part 21 protrudes downward from the second powder outlet 53. In this embodiment, the powder scraping part 21 passes through the rotating shaft L and extends to opposite sides of the bottom wall of the powder pressing part 2. Two second powder outlets 53 are provided and are respectively opened on the bottom wall of the powder pressing part 2. On both sides of the scraper 21, the two second powder outlets 53 are arranged symmetrically along the rotation axis L. By setting the scraper 21, the powder distributor 10 of this utility model can promptly disperse the coffee powder located below the second powder outlets 53 during the powder distribution process, preventing it from accumulating below the second powder outlets 53. By setting the pressing surface 22, the scraper 21 flattens the coffee powder in the extraction container while the pressing surface 22 presses down on the coffee powder, making the coffee powder density uniform throughout the extraction container, and also ensuring more space between the extraction container and the second powder outlets 53.

[0033] Reference Appendix Figure 3, Figure 4 and Figure 5 In a preferred embodiment, the bottom wall of the powder pressing part 2 of the powder dispenser 10 of this invention is provided with powder pressing surfaces 22 located on both sides of the powder scraping part 21. Each powder pressing surface 22 extends upward from the edge of the bottom wall of the powder pressing part 2 along a direction perpendicular to the powder scraping part 21 to the powder scraping part 21. In this embodiment, each powder pressing surface 22 includes a middle region 221, a left region 222, and a right region 223. The right region 223, the middle region 221, and the left region 222 are arranged sequentially along the direction of extension of the powder scraping part 21. The middle region 221 is concave upward relative to the left region 222 and the right region 223. The middle region 221 is tangentially connected to both the left region 222 and the right region 223. The second powder outlet 53 is opened in the left region 222 or the right region 223. By setting the middle region 221 to be concave, the powder pressing part 222 is provided with powder pressing surfaces 222 located on both sides of the powder scraping part 21. The left region 222 and the right region 223 are concave upwards, and the second powder outlet 53 is opened in the left region 222 or the right region 223, so that there is more space between the middle region 221 and the extraction container, so that the coffee powder between the second powder outlet 53 and the extraction container can be dispersed to the middle region 221 in time, avoiding the accumulation of coffee powder in the second powder outlet 53; by setting the middle region 221 to be tangentially connected to both the left region 222 and the right region 223, the coffee powder can be evenly distributed; in this embodiment, an anti-cavity groove 24 is formed by the upward concavity of the tamping surface 22, and the anti-cavity groove 24 extends from the middle region 221 to the second powder outlet 53; by setting the anti-cavity groove 24, more space is provided between the extraction container and the tamping surface 22 to accommodate coffee powder, avoiding the accumulation of coffee powder between the second powder outlet 53 and the extraction container.

[0034] Reference Appendix Figure 3 In a preferred embodiment, the side wall of the pressing part 2 of the powder dispenser 10 of this invention has protruding ribs 26. During the powder dispensing process, the side wall of the pressing part 2 is in clearance fit with the extraction container, and the protruding ribs 26 contact the side wall of the extraction container to promptly scrape off the coffee powder adhering to the side wall of the extraction container. In this embodiment, the protruding ribs 26 are vertically arranged. In other embodiments, such as... Figure 6 As shown, the upper end of the rib 26 is inclined toward the rotation direction A of the powder distributor 10.

[0035] Reference Appendix Figure 4 In a preferred embodiment, the angle r of the side wall of the first section 4 of the powder dispenser 10 of this invention tilting from bottom to top toward the direction away from the rotation axis L ranges from 5° to 30°, preferably 15°, so as to ensure that coffee powder can be smoothly gathered from the first section 4 to the first powder outlet 42.

[0036] In reference appendix Figure 3 In a preferred embodiment, the sum of the cross-sections of all the branching sections 511 of the powder distributor 10 of this invention is greater than the size of the first powder outlet 42, so as to ensure that the coffee powder gathered at the intersection 52 can be transported away from each of the branching sections 511 in a timely manner to avoid accumulation. The distance from the first powder outlet 42 to the second powder outlet 53 is less than the distance from the powder inlet 41 to the first powder outlet 42 to prevent coffee powder from accumulating in the second section 5.

[0037] Reference Appendix Figure 2 and Figure 4 The powder distributor 10 of this utility model includes a first part 10a and a second part 10b. The first segment 4 is disposed in the first part 10a and the second segment 5 is disposed in the second part 10b. The first part 10a and the second part 10b are formed separately to facilitate the manufacture of the powder distributor 10 and simplify the manufacturing process of the powder distributor 10.

[0038] The working principle of this utility model of a beverage device is as follows: The extraction container is placed below the powder distributor 10, and the tamping part 2 extends into the extraction container. At the same time, the driving mechanism 20 drives the powder distributor 10 to rotate. Coffee powder is transported from the powder inlet 41 into the first section 4, and under the action of gravity, it enters the confluence 52 from the first powder outlet 42, then enters each of the branch sections 511, and finally enters the extraction container from the second powder outlet 53. During the rotation of the powder distributor 10, the powder scraping part 21 will scrape the coffee powder accumulated below the second powder outlet 53 in time to make the coffee powder evenly distributed in the extraction container. At the same time, the tamping surface 22 presses down on the coffee powder in the extraction container until the powder distribution is completed.

[0039] The beneficial effects of the technical solution of this utility model of a coffee powder dispenser and beverage equipment are as follows: By setting the cross-section of the first section to gradually decrease from the powder inlet to the first powder outlet, the coffee powder can gradually gather during the process of the dispenser distributing coffee powder to the extraction container, so that the coffee powder has enough gravity to overcome static electricity and fall down, avoiding the coffee powder from adhering to the first section and forming a pile; in addition, since the first powder outlet is the part with the smallest aperture of the first section, the intersection is located below the first powder outlet, avoiding the separation ribs being located at the first powder outlet and causing coffee powder blockage.

[0040] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
