Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and in particular to a coffee grinder with adjustable grinding gap. Background Technology

[0002] The existing coffee grinder, as seen in Chinese Utility Model Patent CN219229669U, entitled "Dual-Adjustment Coarse / Fine Structure for Coffee Grinder and Coffee Grinder," authorized on June 23, 2023, includes a housing, a grinding assembly, a gap adjustment assembly, a coarse adjustment assembly, and a fine adjustment assembly. The grinding assembly includes a fixed grinding disc mounted on the housing and a movable grinding disc mounted on the housing that can move up and down. A grinding gap is formed between the movable and fixed grinding discs. By linking the coarse adjustment assembly and the gap adjustment assembly, the movable grinding disc can be moved up and down, thereby achieving coarse adjustment of the grinding gap to change the coarseness of the coffee bean powder. At the same time, by linking the fine adjustment assembly and the gap adjustment assembly, the movable grinding disc can be moved up and down, thereby achieving fine adjustment of the grinding gap. This allows for both coarse and fine adjustment of the grinding gap, resulting in a more precise division of the fineness of the ground powder to meet different user needs.

[0003] However, the above-mentioned coffee grinder still has the following shortcomings: (1) The above-mentioned coffee grinder's adjustment gap structure includes a gap adjustment component, a coarse adjustment component and a fine adjustment component. The three components involve a large number of parts, have a complex structure and are cumbersome to operate, which makes it inconvenient for users to adjust the grinding gap and maintain the product, and is not conducive to the promotion and application of the product. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a coffee grinder with fewer parts, simple structure, and convenient user operation with adjustable grinding gap.

[0005] The purpose of this utility model is achieved as follows:

[0006] A coffee grinder with an adjustable grinding gap includes a main unit, a feed box assembly, a first grinding element, and a second grinding element. The main unit has a grinding space, and the first grinding element is rotatably mounted in the grinding space. The grinder also includes an adjustment component. The feed box assembly is rotatably connected to the main unit, and one end of the feed box assembly is linked to the adjustment component. The other end of the second grinding element is linked to the adjustment component. The second grinding element is located on the outer periphery of the first grinding element, and a grinding gap is formed between the second and first grinding elements. In this coffee grinder, the feed box assembly moves the second grinding element via the adjustment component to adjust the grinding gap. That is, rotating the feed box assembly adjusts the grinding gap without requiring other components, resulting in fewer parts and a simpler structure, which also facilitates user operation.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Furthermore, it also includes an intermediate transmission component, which is movably mounted on the main unit. The two ends of the intermediate transmission component are respectively linked to the feed box assembly and the adjustment assembly. This allows the feed box assembly to drive the adjustment assembly through the intermediate transmission component, while also facilitating the positioning of the feed box assembly and the adjustment assembly on the main unit and simplifying the transmission structure of the feed box assembly and the adjustment assembly.

[0009] Specifically, the adjustment assembly includes an outer adjustment ring and an inner adjustment ring. The outer adjustment ring is connected to one end of the intermediate transmission component, and the inner circumference of the inner adjustment ring is connected to the second grinding component. The inner adjustment ring is located inside the outer adjustment ring, and the inner circumference of the outer adjustment ring is connected to the outer circumference of the inner adjustment ring in a transmission connection. This is so that when the outer adjustment ring rotates, it drives the inner adjustment ring to move, thereby realizing the movement of the second grinding component.

[0010] Specifically, the upper part of the intermediate transmission component is provided with a groove, the lower part of the feed box assembly is provided with a protrusion extending into the groove, the lower inner circumference of the intermediate transmission component is provided with a raised strip, the upper outer circumference of the adjusting outer ring is provided with a concave portion, and the lower part of the intermediate transmission component is fitted onto the upper outer circumference of the adjusting outer ring with the raised strip extending into the concave portion. The intermediate transmission component is connected to the feed box assembly and the adjusting outer ring respectively through the cooperation of the protrusion and the groove, and the cooperation of the raised strip and the concave portion. These two connection methods have simple structures and stable connections, which are conducive to the linkage between the intermediate transmission component, the feed box assembly and the adjusting outer ring.

[0011] Specifically, the inner circumference of the adjusting outer ring is provided with internal threads, and the outer circumference of the adjusting inner ring is provided with external threads, and the external threads are connected to the internal threads in a driving connection; this thread drive method is convenient to operate and has stable transmission.

[0012] Specifically, the second grinding element is a grinding disc, the upper outer periphery of which is provided with a groove, and the upper inner periphery of the adjusting inner ring is provided with a locking block, which is inserted into the groove by rotation to achieve a stable connection of the grinding disc on the adjusting inner ring.

[0013] Furthermore, the main unit is also equipped with a micro switch, and the outer periphery of the intermediate transmission component is provided with a triggering protrusion for activating the micro switch; only when the feed box assembly is installed in place and the feed box assembly drives the intermediate rotating component to rotate, the intermediate rotating component triggers the micro switch through the triggering protrusion, thereby controlling the conduction of the working circuit in the main unit, making the coffee grinder safer to use.

[0014] Specifically, the outer periphery of the intermediate transmission component extends outward with an arc-shaped strip, the length of which accounts for one-quarter to one-third of the outer periphery length of the intermediate transmission component, and the arc-shaped strip constitutes the actuating protrusion; the arc-shaped strip is relatively long so that the intermediate rotating component can maintain the actuation of the micro switch when rotating to adjust the grinding gap.

[0015] Specifically, it further includes a hollow main unit cover, which covers the upper part of the main unit. The upper end of the main unit cover extends inward to form a support portion with an insertion port. The lower part of the feed box assembly is provided with a locking buckle. The feed box assembly is rotatably connected to the main unit cover so that after the locking buckle passes through the insertion port, the locking buckle is close to the inner side of the support portion. The support portion can both support the feed box assembly to achieve stable installation of the feed box assembly on the main unit and restrict the locking buckle to lock the feed box assembly on the main unit. The implementation effect is good.

[0016] Specifically, the feeding box assembly includes a bean box, a bean sealing plate, and a bottom cover. The bean box has a bean discharge port at the bottom and is connected to the bottom cover. The bean sealing plate is rotatably connected between the bean box and the bottom cover and closes the bean discharge port. An operating part is provided on the bean sealing plate. The user can control the rotation of the bean sealing plate through the operating part, thereby controlling whether the bean sealing plate closes or not. The operation is simple and the implementation effect is good.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) In this coffee grinder, the feed box assembly moves the second grinding piece through the adjustment component to adjust the grinding gap. That is, the grinding gap can be adjusted by rotating the feed box assembly. No other parts need to be set up, which makes the product have fewer parts and a simpler structure. This also makes it easier for users to operate.

[0019] (2) The feed box assembly drives the adjustment assembly through the intermediate transmission component, which facilitates the position setting of the feed box assembly and the adjustment assembly on the main machine and simplifies the transmission structure of the feed box assembly and the adjustment assembly.

[0020] (3) Only when the feed box assembly is installed in place and the feed box assembly drives the intermediate rotating part to rotate, the intermediate rotating part touches the micro switch through the touch protrusion, and then the micro switch controls the conduction of the working circuit in the main unit, making the coffee grinder safer to use.
