Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Reference Figures 1 to 7 This utility model provides a powder presser, including a main body sleeve 1, an adjusting sleeve 2, and a powder pressing unit.

[0022] The main body sleeve 1 is connected to the powder bowl 5. Preferably, the connection is detachable. Furthermore, it is preferable to have several ear loops 51 on the outer wall of the powder bowl 5. The lower part of the main body sleeve 1 has a corresponding slot 12 at the position of each ear loop 51. The slot 12 can engage with the corresponding ear loop 51 to achieve the connection between the main body sleeve 1 and the powder bowl 5.

[0023] The adjusting sleeve 2 is threadedly connected to the main body sleeve 1. Preferably, the adjusting sleeve 2 has an internal thread and the main body sleeve 1 has an external thread. The internal thread and the external thread form a threaded connection. During the process of turning the adjusting sleeve 2, the adjusting sleeve 2 can rotate relative to the main body sleeve 1, thereby adjusting the relative position of the adjusting sleeve 2 and the main body sleeve 1 in the axial direction.

[0024] One end of the tamping unit can extend into the coffee bowl 5 and the other end is movably connected to the adjusting sleeve 2. Driven by the adjusting sleeve 2, the tamping unit can tamp the coffee powder inside the coffee bowl 5.

[0025] The tamper mentioned in this embodiment only requires turning the adjusting sleeve 2 to rotate relative to the main body sleeve 1, which can drive the tamping unit to tamp the coffee powder inside the coffee bowl 5. The overall operation is simpler and less strenuous. By simply rotating the adjusting sleeve 2, the downward pressing distance of the tamping unit can be controlled, achieving easy tamping and obtaining an ideal coffee puck.

[0026] As an optional implementation, the powder pressing unit includes a rotating screw sleeve 31, a first bearing 32, a connecting screw 33, a powder pressing plate 34, a pressure display component 35, a pressure spring component 36, and a reset component 37.

[0027] The rotating screw sleeve 31 is movably connected to the adjusting sleeve 2 through the first bearing 32, and the rotating screw sleeve 31 can rotate relative to the adjusting sleeve 2 with the assistance of the first bearing 32.

[0028] The upper end of the connecting screw 33 is rotatably connected to the lower end of the rotating sleeve 31, allowing relative rotation between them. Furthermore, it is preferable to provide a drive thread at the upper end of the connecting screw 33 and a drive thread at the lower end of the rotating sleeve 31, forming a threaded connection between the two drive threads. After the lower end of the connecting screw 33 passes through the main body sleeve 1, it extends into the coffee bowl 5 and connects with the tamping plate 34. The tamping plate 34 can form a pressing contact with the coffee powder inside the coffee bowl 5. The main body sleeve 1 can prevent the connecting screw 33 from rotating relative to the main body sleeve 1, so that the connecting screw 33 can only slide axially relative to the main body sleeve 1 and cannot rotate relative to the main body sleeve 1.

[0029] The pressure display assembly 35 is connected to the connecting screw, and the pressure spring assembly 36 is sleeved on the upper part of the connecting screw 33 and located below the rotating sleeve 31.

[0030] The reset assembly 37 is sleeved on the lower part of the connecting screw 33 and located above the main body sleeve 1. The reset assembly 37 can restore its deformation and reset after the pressure is released.

[0031] As an optional implementation, the pressure display assembly 35 includes a fixing screw 351, a pressure display gauge 352, and a limiting sleeve 353.

[0032] After the fixing screw 351 passes through the pressure display gauge 352, it forms a threaded connection with the upper end of the connecting screw 33.

[0033] The limiting sleeve 353 is fitted onto the outside of the fixing screw 351, and its lower end is integrally connected to the connecting screw 33, so that the limiting sleeve 353 and the connecting screw 33 form a whole to improve the structural strength. Its upper end is in contact with the pressure display gauge 352.

[0034] A pointer 311 is provided on the rotating screw sleeve 31, and a pressure display 352 is located above the pointer 311. The pressure display 352 has a digital mark 3521 arranged circumferentially outside the projection range of the pointer 311. When the rotating screw sleeve 31 rotates, it can drive the pointer 311 to point to the corresponding digital mark 3521, thereby displaying the pressure in real time.

[0035] As an optional implementation, the connecting screw 33 includes a first rod segment 331, a baffle 332, a polygonal sliding rod 333, and a second rod segment 334 connected sequentially from top to bottom, and together they form an integral connecting structure to ensure the structural strength of the connecting screw 33.

[0036] The first rod segment 331 has a first sliding thread on the outer wall of its upper end, and the rotating sleeve 31 has a second sliding thread on the inner wall of its lower end. The first rod segment 331 and the rotating sleeve 31 can be threaded together through the first sliding thread and the second sliding thread.

[0037] The diameter of the baffle 332 is larger than the diameter of the first rod segment 331, and also larger than the distance between the two furthest points on the cross section of the polygonal sliding rod 333, thus ensuring its relatively outward convex structural form.

[0038] The main body sleeve 1 has a polygonal hole 11. The shape of the polygonal hole 11 matches the cross-sectional shape of the polygonal sliding rod 333. The polygonal sliding rod 333 can slide relative to the polygonal hole 11. At the same time, the polygonal shape causes the polygonal hole 11 to prevent the relative rotation of the polygonal sliding rod 333, so that the connecting screw 33 can only slide relative to the polygonal hole 11 and cannot rotate relative to it.

[0039] The accompanying drawings of this embodiment show the structural form when the cross-sectional shape of the polygonal sliding rod 333 is preferably hexagonal, so the polygonal hole 11 corresponds to a hexagonal hole.

[0040] The second rod section 334 is threadedly connected to the powder pressing plate 34, making disassembly and assembly more convenient and quick.

[0041] As an optional implementation, the pressure spring assembly 36 includes a first spring 361, a bearing clearance plate 362, and a second bearing 363. The bearing clearance plate 362 is movably connected to the connecting screw 33 through the second bearing 363. The first spring 361 is sleeved on the outside of the first rod segment 331, and the two ends of the first spring 361 are in contact with the rotating screw sleeve 31 and the bearing clearance plate 362, respectively.

[0042] The first spring 361 is a compression spring. During the relative rotation of the rotating screw sleeve 31, the first spring 361 can be compressed or released synchronously. The addition of the bearing clearance plate 362 and the second bearing 363 helps the first spring 361 to undergo normal compression deformation.

[0043] As an optional implementation, the reset component 37 is a second spring, which is sleeved on the outside of the polygonal sliding rod 333, and the two ends of the second spring are in contact with the lower surface of the baffle 332 and the main body sleeve 1, respectively.

[0044] The second spring is a return spring. When subjected to pressure, the second spring can be compressed and can return to its original shape after the pressure is released.

[0045] As an optional implementation, a transparent cover 4 is also included. The transparent cover 4 is connected to the adjusting sleeve 2 and is located above the pressure display component 35. The top of the adjusting sleeve 2 is preferably provided with a slot for the transparent cover 4 to be installed. The transparent cover 4 is engaged with the slot. The transparent cover 4 can protect the pressure display component 35, and the operator can observe the pressure display component 35 directly through the transparent cover 4.

[0046] The method of using the powder press and its application principle are as follows: In the specific use process, first place the powder press flat on the mouth of the powder bowl 5, rotate the main body sleeve 1 clockwise, and connect it with the corresponding ear 51 through the locking position 12 to achieve relative fixation between the main body sleeve 1 and the powder bowl 5.

[0047] Then, rotate the adjusting sleeve 2 clockwise. The adjusting sleeve 2 and the main body sleeve 1 move relative to each other through the right-hand thread, so that the adjusting sleeve 2 can move downward relative to the main body sleeve 1 and move towards the powder bowl 5. During the movement, the adjusting sleeve 2 can transmit force downward sequentially through its pressure plate platform. The first bearing 32, the rotating sleeve 31, and the connecting screw 33 are subjected to force in sequence, which further drives the powder pressing plate 34, the pressure display component 35, and the pressure spring component 36 to move downward. The reset component 37 is compressed. During this process, since it is in a state of no resistance, the rotating sleeve 31 will not rotate, and the pointer 311 remains in the zero state.

[0048] When the tamping unit at the bottom, the tamping plate 34, comes into contact with the coffee powder, it generates resistance. At this time, as the adjusting sleeve 2 continues to rotate, it drives the first bearing 32 and the rotating screw sleeve 31 to move synchronously. Meanwhile, the tamping plate 34, the connecting screw 33, and the pressure display assembly 35 cannot move down synchronously with the adjusting sleeve 2, causing the pressure spring in the pressure spring assembly 36 to compress. The rotating screw sleeve 31 begins to rotate, and at the same time, it drives the pointer 311 to start swinging, which corresponds to the number 3521 on the pressure display 352.

[0049] During this process, the greater the resistance, the greater the rotation angle of the rotating sleeve 31, and the greater the synchronous swing angle of the pointer 311. Furthermore, the elastic force of the tension spring corresponding to the first spring 361 is preferably matched with the scale setting on the pressure display 352. Therefore, the specific force of pressing the powder can be intuitively observed from the pressure display 352, thereby accurately controlling the pressure and obtaining a powder cake with ideal density.

[0050] Users can press powder according to their desired texture, precisely control the pressure using the powder press mentioned in this embodiment, and easily press powder.

[0051] It is worth noting that the thread pitch between the adjusting sleeve 2 and the main body sleeve 1 should not be too large. The degree of rotation and the lever arm length are proportional to the pressing distance. Therefore, the larger the diameter of the adjusting sleeve 2, the less force is required to rotate the adjusting sleeve 2, and the easier it is to rotate the adjusting sleeve 2 to achieve easy powder pressing.

[0052] After the powder is pressed, rotate the adjusting sleeve 2 counterclockwise to reverse the operation of the above-mentioned structural components. Wait for the pointer 311 to return to zero, and with the help of the second spring, the powder pressing unit can be easily reset. At the same time, during the counterclockwise rotation of the adjusting sleeve 2, the connection between the locking position 12 and the locking ear 51 can be released, thereby separating the powder presser from the powder bowl 5, saving operation time and steps, and improving separation efficiency.

[0053] The above are merely specific embodiments 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 scope of the claims.
