Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, specifically to a coffee grinder with adjustable coffee bean particle size. Background Technology

[0002] Coffee beans are the fruit of a plant used to make coffee. The caffeine in coffee beans can stimulate the central nervous system and increase its excitability, thus having a refreshing effect and helping people stay awake and energetic. The main reason for grinding coffee beans into powder is to increase the surface area, thereby improving extraction efficiency and allowing the aroma and flavor of coffee to be released better. After coffee beans are ground into powder, the surface area increases, and the contact area with water also increases. This helps to extract the soluble substances in coffee more fully, thereby obtaining a richer coffee aroma and flavor. This device is the coffee grinder used for coffee beans.

[0003] During the use of a coffee grinder, the particle size of the coffee powder is usually adjusted by adjusting the distance between the two sets of grinding discs inside. However, this method of adjustment will still produce irregular particles, such as long and thin particles that can pass through the gaps between the grinding discs.

[0004] Therefore, a coffee grinder with adjustable coffee bean particle size is needed to solve the above problems. Utility Model Content

Two sets of blades 7 are installed at the bottom of the outer wall of the rotating shaft 6, and the two sets of blades 7 are symmetrically distributed. A discharge port 8 is provided at the bottom of the interior of the second grinding disc 5, and the bottom of the discharge port 8 extends to the surface of the bottom of the processing chamber 3. A bottom box 9 is installed at the bottom of the processing chamber 3, and a feed box 10 is inserted into the inner side of the bottom box 9. An adjustable screen assembly is provided, which includes an inner groove 13, a rotating disk 14, a screen groove 15, a screen plate 16, a side platform 17, a fixing hole 18, and a fixing bolt 19. The inner groove 13 is provided inside the discharge port 8. The rotating disk 14 is movably installed inside the inner groove 13. The surface of the rotating disk 14 is provided with screen grooves 15. Several screen grooves 15 are provided on the surface of the rotating disk 14. The screen grooves 15 are arranged in a ring. The screen plate 16 is installed inside the screen grooves 15. The bottom right side of the processing box 3 is provided with a side platform 17. The right side of the rotating disk 14 extends to the inner side of the side platform 17. The right side of the bottom end of the side platform 17 is provided with a fixing hole 18. The fixing hole 18 is provided with a fixing bolt 19. The fixing hole 18 is provided with an internal thread. The surface of the fixing bolt 19 is provided with an external thread.

[0025] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, during use, multiple sets of sieve plates 16 with different apertures are distributed on the surface of the rotating disk 14. After the fixing bolt 19 is loosened, the rotating disk 14 can be rotated to switch the sieve grooves 15 with different apertures to connect with the discharge port 8 for powder screening operation.

[0026] The top of the first grinding disc 4 is provided with a mounting groove 20, the inside of which a nozzle 21 is installed. A connecting pipe 22 is installed at the top of the nozzle 21, the top of which extends into the inside of the housing 1, and an air pump 23 is installed at the top of the connecting pipe 22.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, when in use, starting the air pump 23 can accelerate the air through the nozzle 21 and spray it into the interior of the first grinding disc 4 and the second grinding disc 5, which can help to flush the powder inside the first grinding disc 4 and the second grinding disc 5 and avoid excessive powder residue.

[0028] A hopper 11 is installed at the top left side of the processing box 3. A feeding trough 12 is provided at the bottom right side of the inside of the hopper 11. The right side of the feeding trough 12 extends into the inside of the first grinding disc 4. A sliding groove 24 is provided at the bottom of the feeding trough 12. The right side of the sliding groove 24 extends into the inside of the first grinding disc 4. A sealing rod 25 is movably installed inside the sliding groove 24. A pull rod 26 is fixed on the left side of the sealing rod 25. The left side of the pull rod 26 extends into the outside of the processing box 3. A return spring 27 is provided on the outer wall of the pull rod 26.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, when in use, pull the lever 26 outward. After the sealing rod 25 separates from the feeding trough 12, the coffee beans inside the hopper 11 can enter the first grinding disc 4 and the second grinding disc 5 along the feeding trough 12. Release the lever 26, and with the assistance of the return spring 27, drive the sealing rod 25 to reset. The sealing rod 25 can block the feeding trough 12 to perform a sealing treatment and prevent the material from entering.

[0030] Working principle: During use, coffee beans are stored inside the hopper 11. After loosening the fixing bolt 19, the rotating disc 14 is rotated to switch the appropriate sieve plate 16 to the discharge port 8 for sieving coffee powder. Pulling the lever 26 outward drives the sealing rod 25 backward, opening the feeding chute 12 channel. The coffee powder inside the hopper 11 can then be fed into the first grinding disc 4 and the second grinding disc 5 along the feeding chute 12. Releasing the lever 26, with the assistance of the return spring 27, drives the sealing rod 25 to reset, sealing the feeding chute 12. Starting the motor 2 drives the rotating shaft 6 to rotate the blades 7 inside the first grinding disc 4 and the second grinding disc 5. The rotating blades 7 can cut and pulverize coffee beans. During the grinding of coffee beans, when the coffee beans collide with the inside of the first grinding disc 4 and the second grinding disc 5, the teeth inside the first grinding disc 4 and the second grinding disc 5 can assist in crushing the coffee beans. The crushed particles enter the discharge port 8, and the sieve plate 16 connected to the discharge port 8 performs sieving of the particles. The powder that passes through can fall into the material box 10 on the bottom side for collection. The powder that does not pass through can continue to be crushed with the assistance of the blade 7. After the coffee beans are ground, the air pump 23 can be started. The air pump 23 accelerates the gas and sprays it through the nozzle 21 into the inside of the first grinding disc 4 and the second grinding disc 5, which can flush the internal space and the discharge port 8 on the bottom side, and help the residual powder to be discharged through the discharge port 8, reducing powder residue.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
