Description

Technical Field

[0001] This utility model relates to the field of coffee equipment, and in particular to a powder dispenser structure that can increase or decrease gravity and adjust height. Background Technology

[0002] A coffee grounds dispenser is a common tool used in coffee brewing. Typically, coffee grounds are placed in a coffee bowl beforehand, and after being poured into the bowl, they need to be smoothed out. Therefore, existing tools include a ring-shaped dispenser that is placed on the rim of the coffee bowl and has a scraper inside. Rotating the dispenser moves the scraper to smooth the coffee grounds at the rim of the bowl.

[0003] Patent No. ZL201721008912.9 discloses a coffee powder distribution device that can stably and evenly distribute coffee powder. It uses a threaded structure to adjust the height of the bottom scraper, which facilitates the leveling of coffee powder at different heights in the coffee bowl. However, in actual use, it was found that because the height of coffee powder in the coffee bowl is inconsistent each time coffee is brewed, the manually adjusted height of the bottom scraper cannot fully adapt to the height of coffee powder each time, resulting in uneven distribution of coffee powder and affecting the brewing effect. It is necessary to improve it. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a powder dispenser structure that is simple in structure and easy to use for increasing or decreasing gravity and adjusting height.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A powder dispenser structure for adjusting gravity and height includes a powder dispensing plate, a counterweight, a handheld component, an adjusting knob, a shaft assembly, and a limiting assembly. The counterweight is threaded to the top of the handheld component, and the bottom of the handheld component has a mounting cavity. The handheld component is fitted onto the outside of the top of the adjusting knob through the mounting cavity, and the inner wall of the mounting cavity is threaded to the outer wall of the top of the adjusting knob. The adjusting knob is fitted onto the outside of the top of the shaft assembly, and the adjusting knob is engaged with the shaft assembly. The bottom of the shaft assembly is fitted onto the outside of the top of the limiting assembly, and the shaft assembly and the limiting assembly are rotatably connected. The bottom of the limiting assembly has a receiving cavity, and the powder dispensing plate is disposed within the receiving cavity. A central post is located at the center of the bottom of the handheld component, a first central hole is located at the center of the shaft assembly, and a second central hole is located at the center of the limiting assembly. The bottom of the central post passes through the first central hole and the second central hole in sequence and extends into the receiving cavity, where it is threaded to the top of the powder dispensing plate.

[0006] Furthermore, the handheld component is cylindrical, with a counterweight cavity at the top of the handheld component, and the inner wall of the counterweight cavity is threadedly connected to the outer wall of the bottom end of the counterweight component.

[0007] Furthermore, the adjustment knob is ring-shaped, with its top end extending into the mounting cavity and threadedly connected to the handheld component. The outer diameter of the bottom end of the adjustment knob matches the outer diameter of the bottom end of the handheld component, and the outer peripheral wall of the bottom end of the adjustment knob is provided with a toothed structure for easy rotation and gripping.

[0008] Furthermore, the bottom end of the shaft assembly is provided with an annular cavity, which is coaxially arranged with the first central hole; the limiting assembly is cylindrical, and the top end of the limiting assembly is integrally formed with an annular mounting protrusion, which extends into the annular cavity. A rotary bearing is embedded between the outer wall of the mounting protrusion and the inner wall of the annular cavity, and the rotary bearing is fixedly sleeved on the outer circumference of the mounting protrusion.

[0009] Furthermore, the first central hole is sleeved on the outside of the central column and can slide along the height direction of the central column. The inner wall of the first central hole has a polygonal structure, and the outer diameter of the cross section of the outer wall of the central column is adapted to the inner diameter of the first central hole to realize the limiting connection between the central column and the first central hole.

[0010] Furthermore, the powder distribution plate is a cylindrical shell with an open top. The outer diameter of the powder distribution plate is adapted to the inner diameter of the receiving cavity, and the powder distribution plate can slide along the height direction of the limiting kit. A positioning screw sleeve is integrally formed at the center of the top of the powder distribution plate. The top of the positioning screw sleeve is sleeved on the outer side of the bottom end of the central column, and the inner wall of the positioning screw sleeve is threaded to the outer wall of the bottom end of the central column. Several powder distribution contact surfaces are evenly spaced along the circumference of the powder distribution plate at the bottom end. The powder distribution contact surfaces are fan-shaped and are inclined with one side higher and the other side lower.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are: This invention employs a design with a counterweight at the top of the handheld component. During use, the handheld component moves the counterweight, adjustment knob, and powder distribution plate upwards relative to the shaft assembly and limiting assembly. The limiting assembly is then positioned at the port of the coffee bowl. Releasing the handheld component causes the powder distribution plate to fall along with the counterweight, handheld component, and adjustment knob, ultimately landing on the coffee grounds inside the bowl. At this point, the handheld component rotates the powder distribution plate, causing the bottom surface of the plate to distribute the coffee powder. The powder leveling mechanism achieves a smooth distribution of coffee grounds within the coffee bowl. It utilizes the weight of a counterweight, a handle, and an adjustment knob to ensure the bottom of the powder distribution plate contacts the top of the coffee grounds, allowing the plate height to adapt to various coffee grounds heights. This overcomes the limitations of manually adjustable powder distribution plates, ensuring even distribution of coffee grounds. Furthermore, this invention allows for the replacement of counterweights of different weights to apply varying pressures to the coffee grounds, resulting in different brewing effects and effectively improving the overall performance of the powder distributor.

[0012] On the other hand, the design of the handheld part and the adjustment knob being threaded together allows the height of the handheld part, the counterweight, and the powder distribution plate to be adjusted by rotating the adjustment knob. This enables the adjustment of the height range of the powder distribution plate. Within the adjusted height range, the powder distribution plate can contact the top of the coffee powder through the gravity of the counterweight, the handheld part, and the adjustment knob. This expands the height range of the powder distribution plate in the powder distributor, making it more adaptable to coffee powder of different heights and further improving the effectiveness of the invention.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment discloses a powder dispenser structure for increasing or decreasing gravity and adjusting height, including a powder dispensing plate 6, a counterweight 1, a handheld component 2, an adjustment knob 3, a shaft assembly 4, and a limiting assembly 5; The handheld component 2 is cylindrical, with a counterweight cavity 201 at its top. The inner wall of the counterweight cavity 201 is threadedly connected to the outer wall of the bottom end of the counterweight component 1. The bottom end of the handheld component 2 is provided with a mounting cavity 202, and the handheld component 2 is sleeved on the outer side of the top end of the adjusting knob 3 through the mounting cavity 202. A central post 203 for connecting the powder distribution plate 6 is provided at the center of the bottom end of the handheld component 2. The adjustment knob 3 is ring-shaped, with its top end extending into the mounting cavity 202 and threadedly connected to the inner wall of the mounting cavity 202. The outer diameter of the bottom end of the adjustment knob 3 is consistent with the outer diameter of the bottom end of the handheld part 2. The outer peripheral side wall of the bottom end of the adjustment knob 3 is provided with a toothed structure 301 for easy rotation and gripping. The adjustment knob 3 is sleeved on the outer side of the top end of the shaft assembly 4 and is engaged with the shaft assembly 4. The shaft assembly 4 can slide axially and rotate circumferentially relative to the adjustment knob 3. The shaft assembly 4 has a first central hole 401 at its center for connecting with the central column 203. The first central hole 401 is sleeved on the outside of the central column 203 and can slide along the height direction of the central column 203. The inner wall of the first central hole 401 has a polygonal structure. The outer diameter of the cross-section of the outer wall of the central column 203 is adapted to the inner diameter of the first central hole 401 to realize circumferential rotation limit between the central column 203 and the first central hole 401. The bottom end of the shaft assembly 4 has an annular cavity 402, which is coaxially arranged with the first central hole 401. The shaft assembly 4 is set at the top of the limiting assembly 5. The limiting assembly 5 is cylindrical. The top of the limiting assembly 5 has an integrally formed ring-shaped mounting protrusion 501. The mounting protrusion 501 extends into the annular cavity 402. A rotary bearing 7 is embedded between the outer wall of the mounting protrusion 501 and the inner wall of the annular cavity 402. The rotary bearing 7 is fixedly sleeved on the outer circumference of the mounting protrusion 501. The bottom end of the limiting kit 5 is provided with a receiving cavity 502, and the powder distribution plate 6 is disposed in the receiving cavity 502; the center position of the limiting kit 5 is provided with a second center hole 503, and the bottom end of the center post 203 passes through the first center hole 401 and the second center hole 503 in sequence and extends into the receiving cavity 502 and is threadedly connected to the top end of the powder distribution plate 6.

[0017] The powder distribution plate 6 is a cylindrical shell with an open top. The outer diameter of the powder distribution plate 6 is adapted to the inner diameter of the receiving cavity 502, and the powder distribution plate 6 can slide along the height direction of the limiting kit 5. A positioning screw sleeve 601 is integrally formed at the center of the top of the powder distribution plate 6. The top of the positioning screw sleeve 601 is sleeved on the outer side of the bottom end of the central column 203, and the inner wall of the positioning screw sleeve 601 is threaded to the outer wall of the bottom end of the central column 203. A number of powder distribution contact surfaces 602 are evenly spaced along the circumference of the powder distribution plate 6 at the bottom end of the powder distribution plate 6. The powder distribution contact surfaces 602 are fan-shaped and are inclined with one side higher and the other side lower.

[0018] During use, the counterweight, handheld component, and adjustment knob can slide longitudinally relative to the shaft assembly and limit assembly, thereby causing the central column to drive the powder distribution plate to move longitudinally inside and below the receiving cavity, so that the powder distribution plate can use the gravity of the counterweight, handheld component, and adjustment knob to contact and flatten the coffee powder. When the handpiece is rotated, the handpiece, counterweight, shaft assembly, adjustment knob, and powder distribution plate rotate relative to the limiting assembly under the action of the rotating bearing. The limiting assembly is placed on the mouth of the coffee bowl, and the powder distribution plate smooths the coffee powder inside the coffee bowl. When adjusting the height range of the powder distribution plate, the handpiece and the adjustment knob rotate relative to each other. Under the action of the thread, the height of the handpiece changes. The central column at the bottom of the handpiece slides longitudinally relative to the shaft assembly, causing the powder distribution plate to change height. Ultimately, this changes the distance between the powder distribution plate and the inner wall of the top of the receiving cavity. The distance between the powder distribution plate and the inner wall of the top of the receiving cavity is the height range of the powder distribution plate.

[0019] This invention employs a design with a counterweight at the top of the handheld component. During use, the handheld component moves the counterweight, adjustment knob, and powder distribution plate upwards relative to the shaft assembly and limiting assembly. The limiting assembly is then positioned at the port of the coffee bowl. Releasing the handheld component causes the powder distribution plate to fall along with the counterweight, handheld component, and adjustment knob, ultimately landing on the coffee grounds inside the bowl. At this point, the handheld component rotates the powder distribution plate, causing the bottom surface of the plate to distribute the coffee powder. The powder leveling mechanism achieves a smooth distribution of coffee grounds within the coffee bowl. It utilizes the weight of a counterweight, a handle, and an adjustment knob to ensure the bottom of the powder distribution plate contacts the top of the coffee grounds, allowing the plate height to adapt to various coffee grounds heights. This overcomes the limitations of manually adjustable powder distribution plates, ensuring even distribution of coffee grounds. Furthermore, this invention allows for the replacement of counterweights of different weights to apply varying pressures to the coffee grounds, resulting in different brewing effects and effectively improving the overall performance of the powder distributor.

[0020] On the other hand, the design of the handheld part and the adjustment knob being threaded together allows the height of the handheld part, the counterweight, and the powder distribution plate to be adjusted by rotating the adjustment knob. This enables the adjustment of the height range of the powder distribution plate. Within the adjusted height range, the powder distribution plate can contact the top of the coffee powder through the gravity of the counterweight, the handheld part, and the adjustment knob. This expands the height range of the powder distribution plate in the powder distributor, making it more adaptable to coffee powder of different heights and further improving the effectiveness of the invention.
