[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0035] like Figure 1-4 As shown, the utility model provides a coffee powder tamper, comprising a device body and a powder pressing sheet 11, wherein the powder pressing sheet 11 is detachably connected to the device body via a magnetic connection assembly.

[0036] The compressed powder tablet 11 of the utility model is detachably connected to the device body through a magnetic connection assembly, so that the compressed powder tablet 11 can be easily and conveniently removed from the device body, thereby facilitating cleaning and maintenance, and also improving the flexibility of use of the powder press. Different compressed powder tablets 11 can be replaced according to usage needs to meet different extraction requirements, and the application range is wide.

[0037] As an optional embodiment, the device body includes an upper shell 1, a lower shell 6, an adjustment sleeve 3 and a resistance sleeve 5 which are concentrically arranged. The upper shell 1 and the lower shell 6 can be detachably snapped together to form a accommodating chamber for accommodating the adjustment sleeve 3 and the resistance sleeve 5; the upper shell 1 is threadedly connected to the adjustment sleeve 3, and a center column 101 is arranged at the center of the upper shell 1, and the center column 101 extends toward the lower shell 6, and the resistance sleeve 5 is slidably sleeved on the center column 101 of the upper shell 1; a connecting part 601 is arranged on the lower shell 6, and the resistance sleeve 5 is threadedly connected to the connecting part 601; the center column 101 is connected to the magnetic connection assembly through a screw 7, and a through hole for the screw 7 to pass through is opened on the connecting part 601.

[0038] The upper shell 1 is threadedly connected to the adjustment sleeve 3, so that the length of the downward movement of the upper shell 1 can be adjusted, that is, by adjusting the relative position of the upper shell 1 and the adjustment sleeve 3, the distance between the adjustment sleeve 3 and the bottom plate of the lower shell 6 is adjusted, and then the downward movement distance of the upper shell 1 is changed, so as to achieve precise adjustment of the powder pressing depth. In addition, during the downward pressing process, the upper shell 1 drives the central column 101 to slide along the resistance sleeve 5, thereby improving the stability and reliability of the downward pressing stroke.

[0039] The resistance sleeve 5 is threadedly connected to the connecting portion 601 of the lower shell 6, which is convenient for assembly and disassembly.

[0040] The central column 101 is connected to the magnetic connection assembly via the screw 7 , so that the pressed powder sheet 11 and the upper shell 1 are firmly connected together.

[0041] Furthermore, a connecting groove is opened at the lower end of the center column 101, and the inner wall of the connecting groove is provided with a third internal thread segment 1011, and the first end of the screw rod 7 is provided with a third external thread segment 701, and the connection between the center column 101 and the screw rod 7 is achieved through the threaded cooperation of the third internal thread segment 1011 and the third external thread segment 701.

[0042] As an optional implementation, a return spring 4 is further included. The return spring 4 is sleeved on the outside of the connecting portion 601. When the upper shell 1 moves downward, the return spring 4 can be compressed.

[0043] During the powder compression process, the lower shell 6 is engaged with the powder bowl, and the external force drives the upper shell 1 to move the compressed powder sheet 11 downward, compressing the return spring 4. After the powder compression operation is completed, the return spring 4 uses its elastic restoring force to drive the upper shell 1 to drive the compressed powder sheet 11 to return to its original position.

[0044] As an optional implementation, a first internal thread segment 102 is provided on the inner circumferential wall of the upper shell 1 , and a first external thread segment 301 matched with the first internal thread segment 102 is provided on the upper portion of the outer circumferential wall of the adjustment sleeve 3 .

[0045] The upper housing 1 and the adjustment sleeve 3 are connected by threaded matching of the first internal thread section 102 and the first external thread section 301. Moreover, the threaded matching connection mode facilitates the user to adjust the relative position of the upper housing 1 and the adjustment sleeve 3, and further adjust the downward movement stroke of the upper housing 1.

[0046] As an optional implementation, a second external thread segment 501 is provided at the lower portion of the resistance sleeve 5 , and a second internal thread segment 6011 matched with the second external thread segment 501 is provided on the inner peripheral wall of the connecting portion 601 .

[0047] The connection between the lower shell 6 and the resistance sleeve 5 is achieved through the threaded cooperation between the second internal thread section 6011 and the second external thread section 501 .

[0048] As an optional embodiment, the magnetic connection assembly includes a first magnet 9, a second magnet 10 and a magnet ferrule 8. The first magnet 9 and the second magnet 10 are magnetically matched. The upper end surface of the pressed powder sheet 11 is provided with a first mounting groove 1101 for installing the first magnet 9; the first end of the magnet ferrule 8 is threadedly connected to the screw 7, and the second end of the magnet ferrule 8 is provided with a second mounting groove 801 for installing the second magnet 10.

[0049] Furthermore, a fourth external thread segment 702 is provided at the second end of the screw 7, and a fourth internal thread segment 802 is provided at the first end of the magnet ferrule 8, and the connection between the screw 7 and the magnet ferrule 8 is achieved through the threaded cooperation of the fourth internal thread segment 802 and the fourth external thread segment 702.

[0050] The first magnet 9 and the second magnet 10 cooperate with each other to realize a detachable connection between the pressed powder sheet 11 and the device body, which facilitates assembly and disassembly.

[0051] When the pressed powder sheet 11 is close to the magnet ferrule 8, the first magnet 9 and the second magnet 10 attract each other, realizing a quick connection between the pressed powder sheet 11 and the magnet ferrule 8. During the powder pressing process, the first magnet 9 and the second magnet 10 are tightly adsorbed together to ensure that the pressed powder sheet 11 can be firmly fixed on the magnet ferrule 8 without loosening or falling off.

[0052] When the pressed powder tablet 11 needs to be disassembled, it is only necessary to push the pressed powder tablet 11 to displace the first magnet 9 and the second magnet 10 to break the magnetic attraction therebetween, thereby achieving the disassembly of the pressed powder tablet 11 .

[0053] As an optional implementation, a limiting groove 602 is opened at the lower end of the connecting portion 601 to limit the movement of the magnet ferrule 8 .

[0054] During the resetting process of the upper shell 1 , the magnet ferrule 8 can be driven to automatically enter the limiting groove 602 , and the pressed powder sheet 11 abuts against the lower shell 6 .

[0055] As an optional implementation, a third installation groove 1012 is opened on the outer peripheral wall of the central column 101 for installing the rubber ring 2.

[0056] The function of the rubber ring 2 is to increase the friction between the center column 101 and the resistance sleeve 5 to slow down the resetting speed of the decompression powder sheet 11, avoid the compressed powder sheet 11 leaving the powder cake at high speed, prevent the compressed powder cake from being loosened, and reduce the powder remaining on the wall of the powder bowl from being sprayed to the outside by the airflow generated by the rapid resetting of the compressed powder sheet 11.
