Description

Grinding blade safety device for grinding coffee machine

The present invention relates to a pulverized coffee maker, and in particular, to ensure that the distance between the fixed grinding blade and the rotary grinding blade for grinding coffee is always kept within a range that is not in contact with each other. The present invention relates to a grinding blade safety device of a grinding coffee maker, which can prevent the production and prevent the fixed grinding blade and the rotating grinding blade from being damaged due to contact with each other.

Conventional pulverized coffee maker is to adjust the distance between the fixed grinding blade and the rotary grinding blade by the user rotates the handle in order to adjust the size of the grinding particle of the coffee. However, the conventional grinding coffee maker has no safety device in the case of excessively adjusting the distance between the fixed grinding blade and the rotary grinding blade. Therefore, the rotating blade and the fixed blade are in contact with each other by the adjustment of the leading grinding blade, not only to not grind coffee, but also have problems such as metal powder generated by the contact of the grinding blades mixed with the ground coffee. In addition, there was also an uneconomic problem such that the grinding blades were broken and the grinding blades had to be replaced.

In order to solve the above problems, the present proposal does not allow the user to move the handle lower than a certain distance even if the user excessively rotates the handle, so that the distance between the rotary grinding blade and the fixed grinding blade does not always interfere with each other. It is intended to be located within, and to provide the purpose of preventing the generation of metal powder, etc. caused by abrasion along with the protection of the grinding blade.

The configuration of the present invention will be described in detail with reference to FIGS. 1 and 2. Coupling body 112 is formed in the inlet 113 is introduced into the coupling coupled to the center and the fixed grinding blade 109 by lifting up and down to adjust the gap with the rotary grinding blade 110 ( Thread hole 106 formed in the 105, the adjustment screw 107 that is screwed to the screw hole 106 to stop the lower movement of the handle 105 at an appropriate position, and loosening of the adjustment screw 107 In order to prevent the powder coffee by the mold 108 is filled in the screw hole 106, the fixed grinding blade 109 is fixed to the connecting body 112 and the rotary grinding blade 110 is rotated A guide flaw 102 formed on the upper surface of the cup body 101 that can be crushed to a size, a stopper 104 inserted into the guide groove 102 to control the rotational distance of the adjustment screw 107, and the stopper 104. It is installed to give a certain elasticity to always protrude to the upper surface of the cup body 101. Is a configuration including an elastic member 103.

The operation of this proposal will be explained. First, as shown in FIG. 2, when the coffee is introduced into the inlet 113 of the connecting body 112 coupled to the center of the handle 105, the coffee is rotated of the grinding blade 110 and the fixed grinding blade 109. It is inserted inside.

The rotary grinding blade 110 is rotated by a motor (not shown) inside the cup body 101 to crush the coffee and discharge the powder coffee pulverized into a gap generated in the gap with the fixed grinding blade 109 It is discharged to the outside through the (111). At this time, when it is necessary to adjust the powder size of the coffee, when rotating the handle 105, the grinding mill coupled to the interior of the cup body 101, the fixed grinding blade 109 coupled to the connector 112 of the handle 105 It is possible to adjust the gap between the blade 110 and each other. Therefore, when the handle 105 of the present invention is rotated at a constant angle, the fixed grinding blade 109 can be adjusted upward and downward while the powder size of the coffee can be adjusted, and the fixed grinding blade 109 rotates more than a predetermined angle. Below the height of contact with the grinding blade 110, the handle 105 can no longer be rotated.

The reason why the handle 105 cannot be rotated by a predetermined angle as described above is made by the interaction of the stopper 104 and the adjustment screw 107. The stopper 104 is in contact with the bottom surface of the handle 105 in a state of being supported by the elastic member 103 with the guide groove 102 formed on the upper surface of the cup body 101. The adjusting screw 107 coupled to the hole 106 is caught by the stopper 104 during the rotation, and the rotation of the handle 105 can no longer be achieved and the lowering is not possible. For this reason, the handle 105 is always rotated only within a certain angle range, so that the fixed grinding blade 109 does not come into contact with the rotary grinding blade 110. Thus, the fixed grinding blade 109 Since it prevents the generation of metal powder generated by the wear phenomenon due to the contact of the rotary grinding blade 110 can enjoy a very hygienic powder coffee. When the rotary grinding blade 110 or the fixed grinding blade 109 or the like is replaced or the inside of the cup body 101 is cleaned, the stopper 104 is pushed while using a tool such as a screwdriver from the outside. Rotating the handle 105 facilitates rotation of the handle 105, thereby facilitating replacement of parts and cleaning of the inside.

This paper maintains the distance between the fixed grinding blade and the rotary grinding blade in a non-contact state, so that it is possible to suppress the production of metal powder generated by the contact of the grinding blade, thus obtaining a very hygienic coffee maker. Will be.

In addition, since the fixed grinding blade and the rotary grinding blade rotates in a state that does not contact each other, it is possible to protect the grinding blades of each other has a useful effect to improve the grinding efficiency.
