[0028] like Figure 1-4 As shown, this embodiment provides an externally adjustable grinder, including a main shell 1, a material bin 2 is detachably mounted on the top of the main shell 1 by bolts, and since the material bin 2 can be removed and replaced, the material bin 2 of the required capacity can be freely selected, a driving motor 3 is installed inside the main shell 1, and the output shaft of the driving motor 3 is connected to a driving rod 4, the bottom of the driving rod 4 is sleeved with a grinding core fixing piece 51, the outer side of the grinding core fixing piece 51 is sleeved with an inner grinding core 52, the bottom end of the grinding core driving rod 4 is provided with an external thread, and the bottom end of the grinding core driving rod 4 is threadedly connected and fixed with a fixing plug 53, the grinding core fixing piece 51 and the inner grinding core 52 are pressed against the fixing plug 53 to prevent the grinding core fixing piece 51 and the inner grinding core 52 from falling downward, and a clamping block is sleeved on the grinding core transmission rod 4, and the clamping block and the top of the inner grinding core 52 are set against each other to prevent the inner grinding core 52 from moving upward, thereby achieving the position fixing of the inner grinding core 52, and the bottom of the main shell 1 is rotatably connected with an adjusting screw sleeve 71, and the bottom of the main shell 1 and the top of the adjusting screw sleeve 71 are clamped, so that the adjusting screw sleeve 71 can rotate and will not fall downward, and the inner side of the adjusting screw sleeve 71 is provided with an internal thread, and the adjusting screw sleeve 71 is provided with an internal thread. 1 is connected to a grinding core bracket 62 by a thread, and an outer thread matching the inner thread of the adjusting screw sleeve 71 is arranged on the outer side of the grinding core bracket 62, and an outer grinding core 61 is embedded on the inner side of the grinding core bracket 62, and the outer grinding core 61 is sleeved on the outer side of the inner grinding core 52, and a gap is arranged between the outer grinding core 61 and the inner grinding core 52, and the inner diameter of the outer grinding core 61 gradually increases from the middle to the upper and lower ends, and the outer diameter of the inner grinding core 52 gradually increases from top to bottom, so when the outer grinding core 61 moves upward, the gap between it and the inner grinding core 52 will become larger, and when the outer grinding core 61 moves downward, the gap between the outer grinding core 61 and the inner grinding core 52 will become larger. When the outer grinding core 61 is moved, the gap between the inner grinding core 52 and the outer grinding core 61 will become smaller. A decorative cover 63 is fixed to the bottom of the grinding core bracket 62 by bolts. The decorative cover 63 is set against the bottom of the outer grinding core 61 to prevent the outer grinding core 61 from detaching from the grinding core bracket 62. The outer side of the adjusting screw sleeve 71 is provided with a screw cover 72. Rotating the screw cover 72 drives the adjusting thread to rotate. The adjusting screw sleeve 71 rotates and drives the grinding core bracket 62 to move upward or downward. At this time, the outer grinding core 61 moves up and down synchronously, thereby adjusting the size of the gap between the outer grinding core 61 and the inner grinding core 52 and changing the coarseness of the finished particles.

[0029] Specifically, a slide groove 102 is integrally formed inside the main shell 1, and a top block 103 is movably connected inside the slide groove 102. A spring 104 is embedded in the slide groove 102, and the two ends of the spring 104 are respectively set to resist the top block 103 and the inner wall of the slide groove 102. A plurality of grooves 711 are equidistantly distributed on the inner side of the adjusting screw sleeve 71, and one end of the top block 103 is embedded in one of the grooves 711. When the adjusting screw sleeve 71 is rotated, the top block 103 receives the pressure of the adjusting screw sleeve 71 to compress the spring 104, and then when it moves to the next groove 711, the spring 104 pushes the top block 103 into the groove 711, and the top block 103 hits the groove 711 to produce a sound. Each groove 711 corresponds to a gear, representing a different degree of particle coarseness. When adjusting, the user can judge according to the feel and sound, thereby improving the feel of adjustment.

[0030] In addition, a display panel 105 is provided on the outer side of the main shell 1 near the rotary cover 72, and a plurality of coarseness display blocks are evenly distributed on the display panel 105. An indicator needle 721 is provided at a position corresponding to the rotary cover 72 and the display panel 105. In this embodiment, there are five coarseness display blocks, and each coarseness display block is set to a pattern of different sizes according to the size of the coarseness of the particles represented. When the user rotates the rotary cover 72, the indicator needle 721 of the rotary cover 72 corresponds to the position of different coarseness display blocks, which represents the coarseness of the finished particles, so that the user can observe intuitively without repeatedly adjusting the coarseness.

[0031] Specifically, a feed port 211 is provided at the bottom of the silo 2, a feed channel 101 is provided inside the main housing 1, the top of the feed channel 101 is connected to the feed port 211, and the bottom of the feed channel 101 is connected to the grinding core bracket 62. The raw material to be ground is put into the silo 2, enters the feed channel 101 from the feed port 211 by gravity, then falls into the grinding core bracket 62, and finally enters the gap between the outer grinding core 61 and the inner grinding core 52. After the drive motor 3 is started, the inner grinding core 52 is driven to rotate at high speed to grind the raw material.

[0032] Specifically, the internal bolts of the main shell 1 are connected to a main control circuit board 81, and the main control circuit board 81 is connected to the drive motor 3 through a wire. A start button 82 is provided on the main control circuit board 81, and the start button 82 is provided throughout the main shell 1. The drive motor 3 is started by pressing the start button 82, and the drive motor 3 is turned off by pressing it again.

[0033] Furthermore, a display light 83 is embedded in the surface of the main housing 1, and the display light 83 is connected to the main control circuit board 81 through an internal wire. The display light 83 is on when the grinder is working, and the display light 83 is off when the grinder is turned off.

[0034] Furthermore, the internal bolts of the main shell 1 are fixedly connected with a charging circuit board 91 and a battery 92. The charging circuit board 91 and the battery 92 are connected via a wire. A charging interface 911 is welded on the charging circuit board 91. The charging interface 911 is embedded in the surface of the main shell 1. The charging circuit board 91 and the main control circuit board 81 are connected via internal wires. The grinder is powered by the battery 92 and charged by connecting an external power source via the charging interface 911. The grinder comes with a battery 92 for easy use.

[0035] Specifically, the top cover of the silo 2 is provided with a dust cover 21. The dust cover 21 prevents dust from entering the silo 2. In addition, the dust cover 21 and the silo 2 are sealed by a sealing ring 22 to improve the dustproof effect and prevent external water vapor from entering and moisture-proof.

[0036] The working principle of the utility model is as follows: rotating the screw cover 72 drives the adjusting thread to rotate, and the adjusting screw sleeve 71 rotates to drive the grinding core bracket 62 to move upward or downward. At this time, the outer grinding core 61 moves up and down synchronously, thereby adjusting the gap size between the outer grinding core 61 and the inner grinding core 52, and changing the coarseness of the finished particles. In the process of rotating the screw cover 72, every time it rotates a certain distance, the top block 103 hits the groove 711 through the action of the spring 104, producing a crisp sound, thereby improving the adjustment feel. When the user rotates the screw cover 72, the indicator needle 721 of the screw cover 72 corresponds to the position of different coarseness display blocks, which represents the coarseness of the finished particles, so that the user can observe intuitively without repeatedly adjusting the coarseness.
