Description

TECHNICAL FIELD

[0001] The utility model relates to coffee powder pressing technical field, specifically, relate to a horizontal constant pressure powder presser with adjustable pressure. BACKGROUND

[0002] With the improvement of people's living standards, drinking coffee has become a kind of life enjoyment of people, and in the hand-pouring coffee process, powder distribution and powder pressing need to be carried out, and coffee powder pressing is a key step in the process of making espresso coffee.

[0003] Specifically, coffee powder pressing refers to applying vertical downward pressure to coffee powder filled in a powder bowl by means of a special powder pressing hammer, compacting loose coffee powder, so as to form a flat, uniform and moderately dense powder cake. Powder pressing is of great significance, mainly embodied in: firstly, ensuring that water flow can uniformly pass through the coffee powder layer, so that hot water can pass through each part of the powder cake at the same speed and pressure during the extraction process, thereby obtaining uniform extraction effect and avoiding channeling effect (i.e. water flow concentrates through a part of the powder layer, resulting in uneven extraction); secondly, enhancing the stability of extraction, and stable powder cake density helps to control the extraction time and the flavor performance of coffee.

[0004] Patent No. CN202320352199.9 discloses a horizontal constant pressure powder pressing machine. The device is provided with a powder pressing seat, the outer side of which is slidingly connected with a guide sleeve, and a support seat, a pressure rod and other structures are additionally arranged inside the powder pressing seat. During powder pressing, the powder pressing seat is mainly pushed by the elastic force of spring three to perform extrusion action on the powder placed in the bowl. At the same time, when the connecting pipe moves, the inclined groove will slide along the connecting rod, and in this process, spring two is compressed. When the inclined surface of the inclined groove contacts the pressure rod, it will push the pressure rod to slide, and then the elastic force of spring two is released instantaneously, driving the connecting rod to impact the limiting groove, thereby producing sound feedback to prompt the operation state. Since the length of the inclined groove is fixed and cannot be changed, the compression length of spring three is also constant, which ensures that the intensity of powder pressing remains consistent every time.

[0005] However, this powder pressing machine also has obvious limitations. Although it realizes stable constant pressure control, the pressure value is fixed and single, and cannot be flexibly adjusted according to actual needs. In actual production, the characteristics of different materials, such as particle size, viscosity and hardness, are different, and different product specifications have different requirements for powder pressing density and forming effect. Therefore, when facing diversified production needs, the powder pressing machine is difficult to effectively adapt, greatly limiting its application range, and causing its practicality to be greatly discounted.

[0031] In the use of the powder presser of the present application, a powder bowl is prepared in advance and filled with an appropriate amount of coffee powder. The powder presser hammer 1 is inserted into the powder bowl and abuts against the coffee powder. Then, the operator presses the central main cylinder 6, and the resulting force is divided into two parts: one part compresses the first spring 9, and this force is transmitted to the powder presser hammer 1 through the first guide cylinder 7, thereby achieving the pressing of the coffee powder; the other part is transmitted through the cooperation of the lateral part of the second opening 18 and the guide column 17, and the central main cylinder 6 drives the transmission block 11 to slide downward relative to the first guide cylinder 7, thereby compressing the second spring 10. When the first opening 16 of the first guide cylinder 7 causes the transmission block 11 to rotate, the guide column 17 is connected to the vertical part of the second opening 18, and at this time, the elastic force of the second spring 10 is released instantaneously, and the parts rebound instantaneously and hit the upper part of the vertical part, making a sound, which indicates that the pressing has reached the predetermined position, and the operator can release the hand, preparing for the next pressing operation. Since the distance of the sliding of the transmission block 11 is fixed each time, the stroke of the compression of the first spring 9 is constant each time, so the size of the applied force is consistent each time, and stable constant pressure operation can be achieved. In addition, if it is necessary to set the constant pressure, the rotating part 4 can be adjusted to rotate, and the adjusting block 12 is driven to rotate synchronously, thereby adjusting the initial compression amount of the first spring 9, and then completing the setting and adjustment of the pressing force, greatly improving the practicability of the powder presser.

[0032] It should be particularly pointed out that in the initial state, the transmission block 11 is in close contact with the upper part of the first opening 16. At this time, the guide column 17 cooperates with the lateral part of the second opening 18, thereby achieving the relative locking between the central main cylinder 6, the first guide cylinder 7, the first spring 9 and the transmission block 11. It is worth noting that the moving distance of the transmission block 11 in the subsequent movement process is exactly equal to the vertical height value of the first opening 16.

[0033] As a preferred embodiment, the central main cylinder 6 is provided with a first guide sliding groove 14, and the first guide cylinder 7 is provided with a first guide sliding block 15 matched with the first guide sliding groove 14.

[0034] In the above embodiment, the cooperation of the first guide sliding groove 14 and the first guide sliding block 15 can provide accurate guidance for the sliding of the first guide cylinder 7 in the central main cylinder 6, ensure stable and smooth movement, avoid deviation and jamming, and make the force transmission more stable during the pressing operation. When the central main cylinder 6 is pressed to press the powder, the first guide cylinder 7 can always move along the predetermined track, thereby ensuring the stable compression of the first spring 9.

[0035] As a preferred embodiment, the central main cylinder 6 is provided with a second guide sliding groove 19, and the adjusting block 12 is provided with a second guide sliding block 20 matched with the second guide sliding groove 19.

[0036] In the above embodiment, when the adjusting block 12 is rotated to set the initial compression amount of the first spring 9, the second guide slider 20 can slide smoothly along the second guide slot 19, accurately guiding the adjusting block 12, avoiding the adjusting block 12 from shaking or deviating during rotation, and ensuring the stability of the adjusting process. In this way, the operator can more accurately adjust the initial compression amount of the first spring 9, and then accurately set the pressing force during powder pressing, effectively improving the accuracy and reliability of the pressure adjustment of the equipment, and meeting different powder pressing needs.

[0037] As a preferred embodiment, the adjusting block 12 is annular, and an inner thread is arranged on the inner ring surface of the adjusting block 12. The threaded rod 5 is threadedly connected with the inner thread. One end of the threaded rod 5 penetrates through the outside of the center main cylinder 6 and is connected with the rotating part 4.

[0038] In the above embodiment, when the rotating part 4 is rotated, the threaded rod 5 realizes stable linear motion due to the threaded connection, and drives the adjusting block 12 to accurately displace. Since the threaded connection has self-locking characteristics, the position of the adjusting block 12 will not be easily changed after being fixed, ensuring the stability of the initial compression amount setting of the first spring 9, and making the pressing force setting accurate and reliable. Moreover, this structure is simple and compact, easy to operate, and convenient for users to quickly adjust the powder pressing force according to different needs, improving the practicality and adaptability of the equipment.

The rotating part 4 is rotatably arranged on the handle, making the rotation adjustment more flexible, and facilitating users to adjust the pressure at any time according to actual needs. The elastic knob 21 is arranged at the rotating position of the rotating part 4 and the handle. When rotated to a specific angle, the knob will be engaged with the corresponding groove under the action of the spring force, making a clear sound, providing clear operation feedback for the user, informing the user that the adjustment is in place, and also preventing the rotating part 4 from being accidentally rotated to a certain extent, ensuring the stability of the pressure setting, and further optimizing the accuracy and convenience of the operation.

[0042] As a preferred embodiment, the outside of the first guide cylinder 7 is slidably sleeved with a second guide cylinder 8. One end of the second guide cylinder 8 is connected with an annular sheet 2 facing the powder hammer 1.
