AI Technical Summary
In actual operation of existing manual powder presses, due to spring installation angle deviation and user grip angle deviation, the powder pressing working surface of the powder pressing foundation plate is deflected, affecting the powder uniformity and subsequent extraction taste.
A manual powder presser with additional limit frames is designed to limit the movement of the powder pressing plate through the limit frames to ensure that the powder pressing plate is pressed down vertically or rises. Combined with the pressure sensor and display module, the pressure is monitored and adjusted in real time to ensure balance and uniformity of the powder pressing plane.
Through the coordination of the limit frame and pressure sensor, the balance and uniform powder pressing of the powder are achieved, which improves the uniformity and extraction effect of the powder, and provides convenience for real-time pressure monitoring and adjustment.

Technical Field
[0001] The utility model relates to the technical field of powder pressing devices, in particular to a manual powder pressing device. Background Art
[0002] The existing manual powder tamper, see Chinese utility model patent number: 2021224161104, name: a balanced constant force powder tamper, authorization announcement date: April 25, 2023, which includes, including a powder tamper body; the powder tamper body includes a main rod, a powder tamper handle and a powder tamper base plate; the powder tamper handle and the powder tamper base plate are respectively arranged at the upper and lower ends of the main rod; a first force-bearing elastic element is installed between the main rod and the powder tamper handle; a second force-bearing elastic element is installed between the powder tamper base plate and the powder tamper handle; the utility model has a built-in 30-pound force spring between the main rod and the powder tamper handle, and a built-in second force-bearing elastic element between the powder tamper handle and the powder tamper base plate. Through the double spring design, the height adjustment design is eliminated, which is convenient and quick to use, ensuring that the powder tamper maintains balance to press down the coffee powder, so that the powder surface is flat and not tilted, thereby improving the coffee extraction rate.
[0003] However, the manual powder tamping device with the above structure still has the following shortcomings: (1) If the balance of the above powder tamping hammer is achieved only by the constant pressure spring limiter, it is too idealistic in actual operation. In actual operation, the installation angle deviation of the spring and the angle deviation of the user holding the powder tamping handle will cause the powder tamping working surface of the powder tamping base to be tilted, resulting in different uniformity of the pressed powder, which affects the subsequent extraction taste.
