Description

Technical Field

[0001] This utility model belongs to the field of coffee equipment technology, and specifically relates to a coffee grinder with an independent plasma release chamber. Background Technology

[0002] An electric coffee grinder is a device used to process coffee beans into coffee powder, capable of grinding coffee beans into powders of varying coarseness. The plasma release technology in electric coffee grinders primarily addresses the issue of static electricity generated during the grinding process. Coffee beans generate static electricity during grinding, causing the coffee powder to become charged and adhere to the grinder's inner wall or scatter. The ionized air released by the plasma neutralizes the charge carried by the coffee powder, causing it to lose its electrostatic attraction. However, in existing electric coffee grinders, the plasma nozzle is in direct contact with the powder outlet, making it prone to being covered by coffee powder, thus reducing the effectiveness of the plasma.

[0003] Therefore, to address the issue that existing electric coffee grinders have plasma needles that come into direct contact with the powder outlet and are easily covered by coffee powder, a coffee grinder with an independent plasma release chamber is needed. Utility Model Content

[0004] This invention provides a coffee grinder with an independent plasma release chamber, which solves the problem in existing electric coffee grinders where the plasma needle is in direct contact with the powder outlet and is easily covered by coffee powder.

[0006] The powder outlet chamber is located on the main body of the coffee grinder;

[0007] The plasma release chamber is arranged adjacent to the powder dispensing chamber, and the plasma release chamber is located on the main body of the coffee grinder. The plasma release chamber is equipped with a plasma release device.

[0008] To better realize this utility model, further optimizations are made to the above structure. The main body of the coffee grinder includes an upper body and a lower body, the upper body and the lower body are detachably connected, and the upper body and the lower body are provided with openings for engaging the powder dispensing chamber.

[0009] The perimeter of the powder outlet chamber is smaller than that of the upper body, and the perimeter of the cross-section of the powder outlet chamber exposed outside the main body of the grinder is smaller than the perimeter of the cross-section inside the main body of the grinder, so that the powder outlet chamber is engaged with the upper body and the lower body.

[0010] To better realize this utility model, further optimizations are made to the above structure. The plasma release device is a plasma needle, the angle between the opening direction of the plasma release chamber and the opening direction of the powder outlet chamber is no greater than 90 degrees, and the direction of the plasma needle is the same as the opening direction of the plasma release chamber.

[0011] To better realize this utility model, further optimization is made to the above structure.

[0029] Example 1:

[0030] A coffee grinder with an independent plasma release chamber includes a grinder body, a powder outlet chamber 1, and a plasma release chamber 2, wherein the powder outlet chamber 1 is located on the grinder body; the plasma release chamber 2 is located adjacent to the powder outlet chamber 1 and is located on the grinder body, and a plasma release device is provided inside the plasma release chamber 2.

[0031] The above structure, by setting a plasma release chamber 2 on the main body of the coffee grinder, and setting the plasma release chamber 2 adjacent to the powder dispensing chamber 1, allows the plasma release device in the plasma release chamber 2 to be separated from the powder dispensing chamber 1, while still removing static electricity from the coffee powder in the powder dispensing chamber 1 through the plasma release device, and avoids direct contact between the coffee powder and the plasma release device, so that the coffee powder will not be covered by the coffee powder, resulting in a better plasma effect.

[0032] The aforementioned coffee grinder body includes an upper body 3 and a lower body 4. The upper body 3 and the lower body 4 are detachably connected. The upper body 3 and the lower body 4 are provided with openings for engaging the powder dispensing chamber 1.

[0033] The perimeter of the powder dispensing chamber 1 is smaller than that of the upper body 3, and the perimeter of the cross-section of the powder dispensing chamber 1 exposed outside the grinder body is smaller than the perimeter of the cross-section inside the grinder body, so that the powder dispensing chamber 1 is engaged with the upper body 3 and the lower body 4. That is, the longitudinal direction of the powder dispensing chamber 1 is held in place by the upper body 3 and the lower body 4, thus limiting its longitudinal movement. Furthermore, because the perimeter of the powder dispensing chamber 1 is smaller than that of the upper body 3, and the perimeter of the powder dispensing chamber 1 inside the upper body 3 is greater than the perimeter outside the upper body 3, the lateral direction of the powder dispensing chamber 1 is also held in place by the upper body 3 and the lower body 4; this simplifies installation and eliminates the need for additional drilling.

[0034] The aforementioned plasma release device is a plasma needle 5. The angle between the opening direction of the plasma release chamber and the opening direction of the powder outlet chamber 1 is no greater than 90 degrees, and the direction of the plasma needle 5 is the same as the opening direction of the plasma release chamber. Because the direction of the plasma needle 5 is the same as the opening direction of the plasma release chamber, the plasma function is more complete.

[0035] The lower body 4 is provided with an upper insertion structure 6 and a lower insertion structure 7 at its upper and lower ends, respectively. A motor 8 is engaged between the upper insertion structure 6 and the lower insertion structure 7. A gap is left between the two ends of the motor 8 and the central through holes of the upper insertion structure 6 and the lower insertion structure 7. This gap allows for error margins during installation, facilitating installation. During operation, the motor 8 and the rotating shaft 9 automatically find their center under centrifugal force, improving working concentricity.

[0036] A rotating shaft 9 is inserted into the motor 8. A retaining ring 10 is provided at the upper end of the motor 8, which engages with the rotating shaft 9. A first bearing 11 and a second bearing 12 are spaced apart on the rotating shaft 9, and the outer rings of the first bearing 11 and the second bearing 12 are fixed to the upper insertion structure 6. A gap is provided between the second bearing 12 and the retaining ring 10 to allow the rotating shaft 9 to move vertically. This gap allows for easy installation and prevents the rotating shaft 9 from jamming or increasing the load due to foreign object intrusion during operation, thereby achieving an energy-saving effect.

[0037] The aforementioned rotating shaft 9 is connected to the powder sweeper 13 via a first thread. The powder sweeper 13 is located on the aforementioned first bearing 11, and an inner knife 14 is provided on the powder sweeper 13. The inner knife 14 is located on the aforementioned rotating shaft 9, and the first thread has the opposite rotation direction to the inner knife 14. The threaded connection is simple and ensures good concentricity between the powder sweeper 13 and the rotating shaft 9.

[0038] The aforementioned powder sweeper 13 is provided with a transmission post hole 15, and an inner knife 14 transmission post is provided in the transmission post hole 15. The powder sweeper 13 is connected to the inner knife 14 through the inner knife 14 transmission post. That is, the powder sweeper 13 drives the inner knife 14 to rotate through the inner knife 14 transmission post.

[0039] The upper body 3 is connected to the upper insertion structure 6 via fastening screws 16. A spring 18 is mounted on the fastening screw 16, and the spring 18 abuts against the traction member 17. An external blade 19 is located within the traction member 17. By placing the fastening screw 16 below the spring 18, only one hole is needed to install both the fastening screw 16 and the spring 18, reducing the number of holes required and minimizing cleaning dead zones.

[0040] The upper body 3 is provided with a cover, which is threadedly connected to the upper body 3. Rotating the cover on the upper body 3 adjusts the height of the traction member 17, which in turn drives the outer blade 19. That is, the traction member 17 is fixedly equipped with the outer blade 19. By rotating the cover, the traction member 17 is raised or lowered, thereby raising or lowering the outer blade 19. The cover is provided with a scale, allowing the user to intuitively operate the cover to control the height of the outer blade 19.

[0041] The lower body 4 is equipped with a base, which houses a power supply and a plasma generator. The power supply provides electricity to the motor 8, and the plasma generator provides plasma to the plasma needle.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
