Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a multi-serrated blade disc for a coffee grinder. Background Technology

[0002] A coffee grinder grinds coffee beans into the desired coarseness using rotating blades or a conical grinding disc. The main components include the grinding disc, grinding disc base, motor, coffee bean container, and control panel. When coffee beans are poured into the grinding disc, the motor starts and rotates the disc, crushing and grinding the beans into particles. Coffee grinders are mainly divided into manual and electric types.

[0003] Traditional coffee grinders for electric coffee grinders typically have fewer blades, which limits grinding efficiency and increases the force required during grinding. To improve grinding efficiency and enhance the user experience, a new blade design is needed that can increase grinding efficiency and the quality of coffee bean cutting while reducing the required force. Utility Model Content

The coffee grinder includes a blade holder, an inner ring is fixedly connected to the inner side of the blade holder, and a plurality of inner blades are fixedly connected to the inner side of the inner ring. A cutter disc is provided on the inner side of the cutter holder, and a through hole is provided in the middle of the cutter disc; The outer surface of the cutter disc is fixedly connected with a plurality of blades, and each blade is fixedly connected with irregularly shaped serrations. The cutter head is generally conical.

[0007] Preferably, as described in any of the above embodiments, there is a gap between the inner ring and the edge of the cutter head.

[0008] The above-mentioned technical solution refers specifically to a coffee bean grinder blade that improves grinding efficiency, reduces operating force, and increases cutting area by increasing the number of blades and adopting a multi-irregular serration design.

[0009] Preferably, in any of the above embodiments, the cutter head is made of stainless steel, and the top area of ​​the cutter head is smaller than its bottom area.

[0010] The technical solution described above comprises the following core structure: a cutter head, a through hole, cutting edges, and serrations. The cutter head design includes multiple cutting edges, for example, more than 10, significantly increasing the number of cutting edges per unit area, thereby increasing the cutting area. Each cutting edge is designed with irregularly shaped serrations, the shape and distribution of which are specifically designed to improve cutting efficiency and reduce grinding force. The serration design of the cutter head reduces the crushing action during the grinding process, thereby reducing the heat generated by friction.

[0011] Key features: Significantly less effort required: The increased number of blades and irregular serrated design significantly reduce the force required to grind coffee beans, improving the user experience.

[0012] Increased cutting area: Irregular serrations increase the contact area between the blade and the coffee beans, improving cutting efficiency.

[0013] Reduced heat generation: Reducing the grinding action effectively reduces the heat generated during the grinding process, which helps to preserve the original flavor of the coffee beans.

[0014] When the coffee grinder is working, there is a motor inside the grinder. Its output end drives the shaft to rotate at high speed. Screws are used to fix the burr to the shaft. When the burr rotates at high speed, the blades and serrations work together with the inner blade of the inner ring to grind the coffee beans. The coffee bean powder falls into the chamber below through the gap between the inner ring and the burr.

[0015] Preferably, in any of the above solutions, screws are installed in the through hole of the blade disc to achieve coaxial installation of the blade disc on the grinder shaft.

[0016] Preferably, in any of the above schemes, the serrations are arranged obliquely, and the serrations are stacked from top to bottom on the corresponding single cutting edge.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This coffee grinder uses a multi-serrated blade disc, with the disc design containing multiple blades, significantly increasing the number of blades per unit area and thus increasing the cutting area. Each blade is designed with irregularly shaped serrations, the shape and distribution of which are specifically designed to improve cutting efficiency and reduce grinding force; the serrated design of the disc reduces the crushing action during the grinding process, thereby reducing the heat generated by friction.

[0018] These designs offer the following core advantages: Significantly reduced effort: The increased number of blades and the irregular serrated design significantly reduce the force required to grind coffee beans, enhancing the user experience.

[0019] Increased cutting area: Irregular serrations increase the contact area between the blade and the coffee beans, improving cutting efficiency.
