Description

Food processing appliance

Technical Field

The utility model belongs to the technical field of domestic appliance, especially, relate to a food processing utensil.

Background

Along with the technical progress and the economic development, more and more household appliances enter the lives of people, more convenience is brought to the lives of people, and the electric garlic mashing device is a household appliance product which is more fierce in the market at present and is favored by consumers due to the characteristics of lightness and portability.

In the processing process of the existing electric garlic mashing device, mashed garlic powder in a processing cavity is easy to splash and adhere to the bottom of a machine head component, so that the cleaning is difficult, and bacteria can grow if the mashed garlic powder is remained at the bottom of the machine head component for a long time. In addition, the blade directly connected to the head assembly may still or may have a tendency to continue to rotate due to its own inertia during the period of time when the mashing device has just stopped immediately after the end of the process. At this point, if the user removes the nose assembly from the base cup, there is a risk that the blade will fall out of the base cup and scratch the user.

In addition, some of the existing electric mashed garlic devices adopt a magnetic control switch to realize the control of starting and stopping the electric mashed garlic device, and the design of combining the positioning fit between the head assembly and the bottom cup and the triggering of the magnetic control switch is also adopted. For example, in the prior art, a magnetic strip is embedded on a positioning rib of a cup body, and then a corresponding positioning groove is arranged on a head component. During assembly, the cutter shaft is firstly placed into the bottom cup, and then the head assembly is placed above the bottom cup, so that the matching between the head assembly positioning groove and the bottom cup positioning rib is ensured. Because be provided with the magnetic stripe in the end cup location muscle, its magnetism can trigger magnetic control switch, and then realizes switching on of circuit, thereby can enough realize the location cooperation between aircraft nose and the end cup, thereby also can trigger magnetic control switch and open electronic mashed garlic ware simultaneously.

The electric mashed garlic device adopting the scheme combines the positioning matching between the machine head component and the bottom cup and the triggering of the magnetic control switch, but still has certain problems in the aspects of product use safety, product positioning assembly, product use cleaning and the like:

1. in the electric mashed garlic device adopting the scheme, because the head assembly and the cutter shaft are also directly connected, and because the magnetic control switch and the magnetic stripe can be triggered in a certain distance, in the actual use process, the magnetic control switch can also be triggered under the condition that the head assembly and the bottom cup are not completely positioned and matched, and the sharp blade rotates to cause great threat to the safety of a user at the moment.

2. In equipment and location process, the user often can't assemble aircraft nose subassembly positioning groove and end cup location muscle direct alignment, has obvious difference in height between aircraft nose subassembly and the end cup this moment, and the user need realize the cooperation between positioning groove and the location muscle through revolving the aircraft nose subassembly soon, revolves the user experience that the poor sudden reduction of height brought in the adaptation process and feels relatively poor.

3. Most electric garlic mashing device products adopt a structure that a single magnetic strip or double magnetic strips are uniformly distributed on a bottom cup, and are matched with a magnetic control switch in a machine head assembly to realize circuit conduction. When adopting this kind of structure, the user need twist the aircraft nose subassembly and twist great angle and just can rotate the magnetic stripe to the position that can trigger magnetic switch, and the experience that from this brings feels relatively poor. In addition, although increasing the number of magnetic strips can reduce the angle that the user needs to twist so as to optimize the user experience, the cost of the magnetic strips and the magnetic control switch is higher.

4. Because the cutter shaft and the head assembly are directly connected, the garlic powder can be attached to the bottom of the head assembly in the using process, so that the cleaning inconvenience of a user is caused, and the high requirement on the waterproofness of the head assembly is provided.

It will thus be seen that the prior art is susceptible to further improvements and enhancements.
