Description

Technical Field

[0001] This utility model relates to the field of coffee machine equipment technology, and more specifically to a coffee machine adjustment component that makes adjustment more convenient. Background Technology

[0002] A coffee machine is an electrical appliance used for making coffee. They are generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines require manual operation for grinding, tamping, filling, brewing, and removing grounds. Fully automatic coffee machines are fully automated, controlling the entire coffee brewing process from preheating and cleaning to grinding, tamping, brewing, and dispensing. They brew coffee according to scientific data and procedures, requiring only a simple press of a button. In existing semi-automatic coffee machines, the coffee bean grinding mechanism is hand-cranked. The ground coffee powder is collected in a container, and then the beans are ground using a hand crank. The grind size can be adjusted using a rotary disc. However, this adjustment mechanism has a problem in practical use: the triangular disc is prone to jamming, and the lack of a limit point causes it to get stuck when adjusting the grind, requiring force to turn it, which can be inconvenient for some women. In response to this, the inventor proposes a coffee machine adjustment component that is easier to adjust. By improving the grinding component, it can be easily turned in and out by a knob. The knob is equipped with a telescopic spring, which provides a reaction force to facilitate the rebound of the grinding blade and prevent jamming, making it convenient to use.

[0003] To adjust the grind size during coffee bean grinding, an adjustment mechanism is usually installed on the top of the coffee machine. This adjustment is achieved by rotating a vane along a straight screw (as shown in the instruction manual). Figure 1 The adjustment mechanism has defects in application. The vane rotates directly along the straight screw for adjustment, and there is no limiting point between the vane and the base. This makes it easy for the threads to be damaged and jammed when screwing in, requiring a lot of effort to reset. There is no rebound force when screwing out, and it also requires a lot of force to turn back. These are inconvenient for some female users and urgently need to be solved. Therefore, it is necessary to improve the structure of the grinding coarseness adjustment mechanism to make it easy to adjust and effective, more labor-saving, easier for female users, and improve the practicality of the adjustment mechanism. Utility Model Content

[0004] This utility model discloses a coffee machine adjustment component that is more convenient to adjust, and its main purpose is to overcome the above-mentioned shortcomings and disadvantages of the existing technology.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A more convenient adjustment component for a coffee machine includes a grinding base and an adjustment assembly. The adjustment assembly has a straight screw and an adjustment block. The lower part of the straight screw has a grinding core, which is movably inserted into the grinding base. A telescopic spring is sleeved in the middle, and an external thread is provided at the top. The adjustment block is sleeved on the top of the telescopic spring and has a circular groove in the middle of the top. The top of the straight screw has an adjustment knob, and the lower part of the adjustment knob has an insert block. The insert block is embedded in the circular groove and can be screwed in and out through the external thread. The adjustment block can be adjusted up and down by the adjustment knob.

[0007] Furthermore, the adjustment knob has an inner groove with an opening facing downwards, and the inner groove is provided with an internal thread, which is adapted to be screwed into the external thread.

[0008] Furthermore, rotating the adjustment knob clockwise along the external thread drives the adjustment block to move downwards.

[0009] Furthermore, when the adjustment knob is rotated counterclockwise along the external thread, the adjustment block rebounds upwards via the telescopic spring.

[0010] Furthermore, the adjusting block has an inverted frustum structure and its bottom abuts against the telescopic spring.

[0011] Furthermore, the grinding base has a chamfered groove in the middle of its top, and the adjusting block can move up and down along the chamfered groove.

[0012] Furthermore, a rotating gear is provided on the upper outer edge of the adjusting block.

[0013] Furthermore, the grinding base has a built-in bevel gear structure with a hand crank on one side.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention firstly uses an adjustment knob with an embedded block to move the adjustment block up and down, thus adjusting the coarseness of the coffee bean grind. Compared to the existing method of directly rotating a triangular blade up and down, this method ensures that the adjustment block always abuts against the grinding base, finding the limit point and better fixing it, preventing the adjustment block from shifting up and down during grinding. Secondly, driving the adjustment block up and down with the adjustment knob also avoids the common problem of the adjustment block easily slipping out of the groove and becoming difficult to reset in existing structures. The adjustment operation requires no effort and is convenient for women to use. Finally, a telescopic spring is provided at the lower part of the straight screw. The top of the telescopic spring abuts against the adjustment block, and the bottom abuts against the grinding core, which solves the problem of the grinding core easily shifting up and down during grinding, achieving a better grinding effect. This invention has a novel structure, ingenious design, convenient operation, and strong practicality. It can effectively improve the grinding effect of coffee beans and is suitable for widespread application. Attached Figure Description

[0020] Figure 5 This is a schematic diagram of the structure of the adjusting block of this utility model. Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a more convenient coffee machine adjustment component includes a grinding base 1 and an adjustment component 2. The adjustment component 2 is provided with a straight screw 3 and an adjustment block 4. The lower part of the straight screw 3 is provided with a grinding core 31, which is movably inserted into the grinding base 1. A telescopic spring 5 is sleeved in the middle and an external thread 6 is provided at the top. The adjustment block 4 is sleeved on the top of the telescopic spring 5 and has a circular groove 7 in the middle of the top. The top of the straight screw 3 is provided with an adjustment knob 8. The lower part of the adjustment knob 8 is provided with an insert block 9, which is embedded in the circular groove 7 and can be screwed in and out through the external thread 6. The adjustment block 4 can be adjusted up and down by the adjustment knob 8.

[0023] Furthermore, the adjustment knob 8 has an inner groove with an opening facing downwards (not shown in the schematic diagram due to viewing angle), and the inner groove has an internal thread that is adapted to be screwed into the outer thread 6.

[0024] Furthermore, the adjustment knob 8 rotates clockwise along the external thread 6, driving the adjustment block 4 to move downward.

[0025] Furthermore, when the adjustment knob 8 rotates counterclockwise along the external thread 6, the adjustment block 4 rebounds upward via the telescopic spring 5.

[0026] Furthermore, the adjusting block 4 has an inverted frustum structure and its bottom abuts against the telescopic spring 5.

[0027] Furthermore, the grinding base 1 has a chamfered groove 9 at the top center, and the adjusting block 4 can move up and down along the chamfered groove 9.

[0028] Furthermore, a rotating gear 10 is provided on the upper outer edge of the adjusting block 4.

[0029] Furthermore, the grinding base 1 has a built-in bevel gear structure 11, and a hand crank 12 is provided on one side of the bevel gear structure 11.

[0030] Example: First, place the coffee beans under the grinding base 1 and fix the grinding base 1 in place. Grind the coffee beans by rotating the bevel gear 11 through the hand crank 12. Next, adjust the grind size of the coffee beans through the adjustment component 2. When the grind size needs to be finer, rotate the adjustment knob 8 clockwise along the external thread 6, driving the adjustment block 4 to move downward and abut against the chamfered groove 9 of the grinding base 1. At the same time, the telescopic spring 5 is compressed and stored, thus finer grinding of the coffee beans. Next, when the grind size needs to be coarser, rotate the adjustment knob 8 counterclockwise along the external thread 6. The adjustment block 4 rebounds and moves upward through the telescopic spring 5, thus coarser grinding of the coffee beans. Finally, during the grinding of coffee beans, the bottom end of the telescopic spring 5 always abuts against the grinding core 31. Since the upper end of the telescopic spring 5 always abuts against the adjustment block 4, it provides a downward force, preventing the grinding core 31 from shifting up and down, thus achieving a better grinding effect.

[0031] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0032] This invention firstly uses an adjustment knob with an embedded block to move the adjustment block up and down, thus adjusting the coarseness of the coffee bean grind. Compared to the existing method of directly rotating a triangular blade up and down, this method ensures that the adjustment block always abuts against the grinding base, finding the limit point and better fixing it, preventing the adjustment block from shifting up and down during grinding. Secondly, driving the adjustment block up and down with the adjustment knob also avoids the common problem of the adjustment block easily slipping out of the groove and becoming difficult to reset in existing structures. The adjustment operation requires no effort and is convenient for women to use. Finally, a telescopic spring is provided at the lower part of the straight screw. The top of the telescopic spring abuts against the adjustment block, and the bottom abuts against the grinding core, which solves the problem of the grinding core easily shifting up and down during grinding, achieving a better grinding effect. This invention has a novel structure, ingenious design, convenient operation, and strong practicality. It can effectively improve the grinding effect of coffee beans and is suitable for widespread application.

[0033] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
