Abstract
Description
Technical Field
[0001] The utility model belongs to the field of grinding head equipment of grinders, and particularly relates to an inner grinding head structure of a grinder. Background Art
[0002] The working principle of the grinder is that the outer grinding head is fixed, while the inner grinding head rotates. The relative movement of the inner and outer grinding heads squeezes and crushes particles such as coffee beans to form powder.
[0003] The traditional grinding coarseness adjustment is to adjust the knob and the end face of the inner grinding head fixing frame to produce a gear sense. There are several grooves on the end face of the inner grinding head fixing frame (such as Figure 6 ), there are one or more ribs on the adjustment knob (such as Figure 7 ), after assembly, the spring is compressed, giving the inner grinding head a downward thrust, and the inner grinding head fixing frame is fixed to the inner grinding head, so as to ensure that there is a pressure between the adjustment knob and the inner grinding head fixing frame. When the adjustment knob is rotated, the convex point on the knob collides with the convexity or concave pit on the inner grinding head fixing frame, thereby forming a gear sense, such as Figure 8 Although this method has a simple structure, it actually has an obvious defect. During the grinding process, the space between the inner and outer grinding heads is filled with grinding particles and powder, which can easily get stuck. In this way, when the adjustment knob is rotated counterclockwise to increase the gap between the inner and outer grinding heads, the thrust of the spring is not enough to overcome the jamming force between the inner and outer grinding heads, which will cause the adjustment knob to disengage from the inner grinding head fixing frame, with no pressure at all, thereby losing the gear sense.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 5 The utility model provides a technical solution: an inner grinding head 400 structure of a grinder, comprising: an adjustment unit 100, an inner grinding head 400, a non-slip pad 300 installed in an inner grinding head fixing frame 200, and an inner grinding head fixing frame 200, wherein the upper surface of the adjustment unit 100 is recessed inwardly to form a groove 120, an inner side of the groove 120 is provided with an inner ring 130, and the surface of the inner ring 130 is recessed inwardly to form a receiving groove 131;
[0027] Elastic ribs 210 are arranged on both sides of the inner grinding head fixing frame 200 , and the bottom of the inner grinding head fixing frame 200 is movably connected in the groove 120 . At this time, the elastic ribs 210 are stuck in the accommodating groove 131 .
[0028] As an embodiment of the present utility model: a through cavity is formed through the surface of the inner grinding head 400, and the top of the inner grinding head fixing frame 200 pushes the anti-slip pad 300 into the through cavity.
[0029] As an embodiment of the present utility model: the upper and lower surfaces of the adjustment unit 100 are penetrated with a first through hole 110, and the first through hole 110 is used for movably connecting to the grinding spindle.
[0030] The surface of the inner grinding head fixing frame 200 is also penetrated with a second through hole 220, and the second through hole 220 is used to flexibly connect the grinding spindle. Through the first through hole 110 and the second through hole 220, the grinding spindle can be flexibly connected to the adjustment unit 100 and the inner grinding head fixing frame 200, so as to facilitate the grinding operation.
[0031] As an embodiment of the present utility model: a plurality of the accommodating grooves 131 are arranged, and the plurality of accommodating grooves 131 are arranged equidistantly on the surface of the inner ring 130. By providing a plurality of accommodating grooves 131, the elastic rib 210 can be limited from different directions.
[0032] The elastic rib 210 is provided with two groups, and the two groups of elastic ribs 210 are symmetrically arranged on both sides of the inner grinding head fixing frame 200. The surface of the inner grinding head fixing frame 200 is penetrated with a deformation cavity 211 for compensating the action variable when the elastic rib 210 moves inward and outward. When the elastic rib 210 rotates along the inner ring 130, when the elastic rib 210 does not enter the receiving groove 131, the elastic rib 210 squeezes the deformation cavity 211 inward. When the elastic rib 210 enters the receiving groove 131, the deformation cavity 211 pushes the elastic rib 210 outward, so that the elastic rib 210 can better contact the receiving groove 131.
[0033] As an embodiment of the present utility model: during the grinding process, even if the space between the inner grinding head 400 and the outer grinding head is filled with grinding material particles and powder, which jam the inner grinding head 400 and the outer grinding head, thereby causing the adjustment unit 100 to rotate counterclockwise to increase the gap between the inner grinding head 400 and the outer grinding head, the thrust of the spring is not enough to overcome the jamming force between the inner grinding head 400 and the outer grinding head. However, because the receiving groove 131 of the adjustment unit 100 and the elastic rib 210 on the inner grinding head fixing frame 200 both have a certain height, even if the two are separated by a certain distance, the receiving groove 131 and the elastic rib 210 will not be completely separated, so the gear sense still exists.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
