Description

TECHNICAL FIELD

[0001] The utility model relates to a coffee machine hopper device for preventing coffee beans from being stuck. BACKGROUND

[0002] The coffee bean feeding component is one of the components of the coffee bean grinder, and the automatic feeding of the coffee beans of the traditional household coffee machine coffee bean grinder is generally realized through a feeding screw rod. The feeding screw rod is driven by a motor to transport the coffee beans to the direction of the grinding disc. In order to smoothly discharge the coffee beans without being stuck, a guide splash-proof part is used in CN218552143U. However, the opening size of the guide splash-proof part in the technical solution is difficult to match the coffee bean grinding speed, although the phenomenon of the coffee beans jumping out can be reduced, the problem of the coffee beans being stuck cannot be effectively solved. The coffee beans can be stuck in the discharging cavity, which affects the transportation of the coffee beans. When the coffee beans are stuck and the motor continues to rotate, the motor or the feeding screw rod can be damaged. At present, the problem is solved by increasing the hardness of the feeding screw rod and increasing the power of the motor, that is, the coffee beans are crushed at the position where the coffee beans are stuck by the continuous force of the motor. Through the above-mentioned way, the problem of high manufacturing cost and easy damage to the coffee bean grinder exists. SUMMARY

[0027] The following detailed description, in conjunction with the accompanying drawings, provides a further detailed account of specific embodiments of the coffee machine hopper device for preventing coffee bean jamming according to this utility model.

[0028] Example 1: As Figures 1-5 As shown, the coffee hopper device for preventing coffee bean jamming in this embodiment mainly consists of a frame 1, a rotating unit 2, and a coffee hopper 3. Since this patent mainly concerns the feeding problem of the hopper device, the grinding structure for grinding coffee beans, such as the moving grinding disc and the fixed grinding disc installed at the bottom of the frame 1, is not shown in the figure. The rotating unit 2 of the hopper device consists of a motor 20, a rotating shaft 21, and a mounting lug 22. It is installed inside the frame 1 via the mounting lug 22. The coffee hopper 3 is installed on the top of the frame 1. A stirrer 4 is provided in the feed chamber of the coffee hopper 3, including a mushroom-shaped structure 41 at the upper end and a central connecting rod 42. The stirrer 4 is rotatably mounted on the rotating shaft 21 of the rotating unit 2. The stirrer 4 has an eccentric structure. When the rotating shaft 21 rotates, the stirrer 4 rotates eccentrically inside the coffee hopper 3, stirring the coffee beans inside the coffee hopper 3. In this embodiment, the eccentric structure is a connector 5 with an eccentric through hole 50. The stirrer 4 has a connecting hole 43 in the middle, and the connector 5 is disposed in the connecting hole 43 and fixed to the rotating shaft 21 by a screw 6. When the rotating shaft 21 rotates, the mushroom-shaped structure 41 of the stirrer 4 rotates non-statically relative to the coffee hopper 3, thereby agitating the coffee beans and preventing them from getting stuck and not falling. To improve the mechanical strength of the stirrer 4, vertical ribs 45 can be provided on the circumferential surface of the central connecting rod 42 of the stirrer 4. These vertical ribs 45 also agitate the coffee beans at the bottom. In addition, to increase the agitation effect in the vertical direction, downward flanges 46 can be provided on the outer periphery of the mushroom-shaped structure 41 of the stirrer 4. Furthermore, radially distributed corrugated guide grooves or ridges (not shown in the figure) can be provided on the upper surface of the mushroom-shaped structure 41 of the stirrer 4.

[0029] Example 2: Its main structure is basically the same as that of Example 1, except that, as Figure 6 , Figure 7As shown, the eccentric structure of the present embodiment is a mounting hole 44 directly eccentrically opened on the stirrer 4, and the stirrer 4 is installed on the rotating shaft 21 through a screw rod 6 passing through the mounting hole 44.

[0030] Embodiment three: the main structure is basically the same as that of embodiment two, and the difference is that, as shown in Figure 8 As shown, the eccentric structure of the present embodiment is a mushroom head-shaped structure 41 with a non-circular structure, and the present embodiment adopts an elliptical mushroom head-shaped structure 41.

[0031] Embodiment four: the main structure is basically the same as that of embodiment one, and the difference is that, as shown in Figure 9 As shown, the convex rib 45 of the present embodiment is a diagonal convex rib, which can further increase the stirring and discharging effect while improving the mechanical strength of the stirrer.

[0032] Embodiment five: the main structure is basically the same as that of embodiment four, and the difference is that, as shown in Figure 10 , Figure 11 As shown, the convex rib 45 of the present embodiment is a local helical convex rib on the circumferential surface, such as a helical convex rib with only half a circle as shown in the figure, or a segmented helical convex rib. Compared with the continuous pushing of the screw rod, the half-circle helical convex rib can achieve intermittent pushing and has a buffering effect, which solves the problem of jamming.

[0033] In addition, the coffee machine hopper device of the above embodiments for preventing jamming can be provided with a radially distributed corrugated guide groove or convex strip on the upper surface of the mushroom head-shaped stirrer (not shown in the figure), which further improves the top stirring effect in the up-down direction.
