Description

Household handheld pulverizer

Technical Field

The invention relates to the technical field of grinders, in particular to a household handheld grinder.

Background

Hand-held shredders are commonly used for the comminution of food ingredients, such as directly edible coriander, cheese, and the like, and may also be culinary spices. The hand-held pulverizer in the prior art is generally pushed axially to provide an axial extrusion force, and needs manpower to drive the hand-held pulverizer to rotate so as to enable food ingredients to be finely pulverized to rotate relative to the blades, and the fine pulverizing process is completed. However, it is easy to see that in this process, a person is required to provide both an axial thrust and a circumferential rotational force, so that a great deal of physical effort is required to be consumed by the person, which is not beneficial to the convenience of operation.

In addition, the grip and the blade of the existing handheld pulverizer are generally arranged at two ends of the working cavity respectively, so that a central shaft is required to be provided between the grip and the blade to transmit driving force, and therefore the central shaft often penetrates through the working cavity, so that the working cavity becomes an annular cavity. This results in the prior art hand-held grinder not being able to directly load large pieces of food ingredients, i.e. the food ingredients need to be chopped first to be thrown in the circumferential direction of the working chamber. Obviously, this prior art hand-held shredder is inconvenient to operate during loading due to the shielding of the central shaft.
