Description

Grinding mechanism and electric grinder and manual grinder with same

Technical Field

The utility model relates to a grinder, in particular to a grinding mechanism, an electric grinder with the grinding mechanism and a manual grinder.

Background

In daily life of people, powdery food materials or seasonings, such as coffee, pepper, black pepper and the like, are often used, and in order to keep the flavor of the food materials, raw materials are grinded before being used, and a grinder is generated. Currently, the grinders in the market are divided into a manual grinder and an electric grinder.

The grinding heads of the existing electric grinder and manual grinder are generally of a structure that an outer grinding head is fixed on a shell, an inner grinding head is fixed on a connecting rod through a knob, the tightness is adjusted through a spring, and the connecting rod is connected with the shell. This structure has the following problems: in the grinding process, the inner grinding head rotates, the outer grinding head is fixed, the ground powder particles continuously leak out from the middle gap between the inner grinding head and the outer grinding head, the inner grinding head can be loose more and more under the reaction of the grinding particles, the ground powder particles can become thicker and thicker, and finally the inner grinding head can be loose.

In order to solve the above problems, the structure commonly used at present is: the inner grinding head is connected with the connecting rod through the grinding head fixing frame and the knob, a plurality of convex hulls are arranged on the top surface of the knob, and about dry concave positions are arranged on the bottom surface of the grinding head fixing frame. The convex hulls on the knob are tightly attached to the concave positions on the grinding head fixing frame through the elasticity of the springs, so that the relative positions of the knob and the grinding head fixing frame do not move in the grinding working process, and the inner grinding head cannot be loosened more and more.

However, the above structure has the following problems: 1. the hand feeling of a user is poor when the user operates the knob under the influence of the spring force, the operation is relatively easy due to the small spring force when the user starts to screw, and the operation is gradually difficult along with the increase of the spring force when the user continues to screw; 2. when the operator operates improperly or after multiple times of use, the convex hulls on the knob are ground flat and lose the functions of the convex hulls when the knob rotates excessively.

Disclosure of Invention

The utility model provides a grinding mechanism, an electric grinder with the same and a manual grinder with the same, which can solve the problem that an inner grinding head of the grinder becomes loose or even falls off after being used for a plurality of times, and simultaneously, the inner grinding head of the grinder is good in use feeling, simple in structure and low in production process and production cost.

The utility model is realized by the following technical scheme:

the utility model provides a grinding mechanism, includes outer bistrique, interior bistrique, adjust knob and bistrique mount, outer bistrique and grinder casing subassembly fixed connection, interior bistrique passes through the bistrique mount reaches adjust knob installs on the grinder transmission shaft, interior bistrique with bistrique mount fixed connection, adjust knob set up in the lower extreme of bistrique mount, the lower extreme lateral wall of bistrique mount is equipped with a plurality of buckle portion, adjust knob's upper end side sets up a plurality of draw-in groove portion, buckle portion joint in the draw-in groove portion.

Through buckle portion with the joint cooperation of draw-in groove portion has realized the bistrique mount with adjust knob's relative fixation, and then realized the relative fixation of interior bistrique and adjust knob, can avoid interior bistrique because the not hard up that uses many times leads to even deviate from effectively, simultaneously because joint portion with draw-in groove portion all sets up in the side, can effectively avoid because the excessive buckle wearing and tearing that leads to of repetitious usage or operator's rotatory knob, the operator feel when rotatory adjust knob simultaneously is better.

Further, threads are arranged at the bottom of the transmission shaft of the grinder, and nuts matched with the threads are arranged in the adjusting knob. The adjusting knob can move up and down on the transmission rod.

The electric grinder is characterized by comprising the grinding mechanism, a power supply assembly, a circuit assembly and a power assembly, wherein the grinder shell assembly accommodates the power supply assembly, the circuit assembly, the power assembly and the grinding structure, the power assembly, the circuit assembly and the power assembly are electrically connected, and the power assembly is connected with a grinder transmission shaft.

The manual grinder comprises a handle assembly and the grinding structure, wherein the handle assembly is arranged on the upper portion of the grinder shell assembly, the grinder shell assembly accommodates the grinding structure, and the handle assembly is connected with a grinder transmission shaft.

The grinding mechanism, the electric grinder with the grinding mechanism and the manual grinder have the advantages that looseness or falling-off of the inner grinding head caused by repeated use can be avoided, meanwhile, the use feeling of an operator is good, the structure is simple, and meanwhile, the production process and the production cost are low.
