[0029] One specific implementation example is Figure 1-2 As shown, a bean hopper cover of an electric coffee bean grinder comprises a mounting bracket 1, the mounting bracket 1 is used for fixing and connecting the bean hopper inlet of the coffee bean grinder, a through bean inlet channel 2 is arranged on the mounting bracket 1, a cover plate 3 is arranged on the mounting bracket 1 in a lifting and adjusting manner, a bean inlet through hole 4 is formed on the cover plate 3, when the cover plate 3 is raised to a first height position away from the mounting bracket 1, a lower bean gap 5 which is through the bean inlet channel 2 is formed between the bean inlet through hole 4 of the cover plate 3 and the mounting bracket 1, when the cover plate 3 is lowered to a second height position close to the mounting bracket 1, the bean inlet through hole 4 of the cover plate 3 contacts the mounting bracket 1 to close the bean inlet channel 2, the connection mode between the cover plate 3 and the mounting bracket 1 can be selected as a sliding connection or a threaded connection, and the height position of the cover plate 3 is adjusted by a direct push type or a spiral type.

[0030] Taking the sliding connection as an example, a slide groove is provided on the mounting bracket 1, and a slider matching the slide groove is provided on the cover plate 3. Preferably, the number of the slide grooves is at least two, which are symmetrically arranged on the mounting bracket 1.

[0031] like Figure 3As shown, the slide groove 18 can extend axially along the mounting bracket 1 in a straight line. Preferably, a positioning groove 19 can be extended laterally near the first height end of the slide groove 18. When the cover plate 3 reaches the first height position by pulling it straight upward, the slider on the cover plate 3 is rotated circumferentially and positioned in the positioning groove 19.

[0032] like Figure 4 As shown, the slide groove 18 can also be set as an inclined groove extending spirally along the outer circumferential surface of the mounting bracket 1. Preferably, a positioning groove 19 can be extended laterally near the first height end of the slide groove 18. When the cover plate 3 reaches the first height position by rotating along the inclined groove, the slider on the cover plate 3 is rotated circumferentially and positioned in the positioning groove 19.

[0033] The cover plate 3 opens and closes the bean inlet channel 2 in a lifting manner, and the user can conveniently operate it in a push-pull or spiral manner. The cover plate 3 and the mounting bracket 1 are not detachable to prevent the cover plate 3 from being lost during use.
