Description

Manual chopper

Technical Field

The utility model belongs to the technical field of food comminution equipment and specifically relates to a manual mincer is related to.

Background

This section merely provides background information related to the present application so as to enable those skilled in the art to more fully and accurately understand the present application, which is not necessarily prior art.

A chopper is a small household appliance widely accepted in kitchens, and performs a food chopping function such as mincing, shredding, fruit and vegetable chopping into granules by rotating and chopping food materials in a chopping cup by a chopping blade mounted in the chopping cup.

The different types of shredders that are powered to remove the shredding blade can be classified into powered shredders and manual shredders. The electric chopper drives the chopping knife to rotate through a transmission structure by the motor, is convenient to use, but has higher cost and higher price, and has certain noise when in use. Manual shredders, however, provide power to the shredding blade in a manual manner by the user, are relatively inexpensive to implement, and do not generate significant noise during use as do electric shredders.

For example, chinese patent application CN201710939692X discloses a manual shredder, which comprises a base, a cup body detachably mounted on the base, and a cup cover covering the cup body; the power transmission assembly is arranged in the base, and the output end of the power transmission assembly extends out of the base upwards; a chopping knife is arranged in the cup body, the upper end of a rotating shaft of the chopping knife is rotatably clamped on the cup cover, and the lower end of the rotating shaft is in driving connection with the output end of the power transmission assembly; a handle is arranged outside the base, and a pull rope is arranged between the handle and the power transmission assembly. When a user pulls the pull rope through the handle, the pull rope is utilized to drive the shredding knife to rotate in the cup body through the power transmission assembly so as to shred the real objects. The technical scheme has the following defects:

1. the manual shredder disclosed by the technical scheme has a complex integral structure. For example, the output end of the power transmission assembly needs to penetrate through the cup body upwards, and a hole needs to be drilled in the bottom of the cup body and a sealing assembly needs to be arranged; if the cup cover is not used, the lower surface of the cup cover is provided with the clamping column, and the upper end of the rotating shaft is provided with the clamping hole matched with the clamping column, so that the rotating shaft of the chopping knife is connected with the rotating clamp of the cup cover. The cup cover assembly structure has the advantages that the overall structure is complex, the implementation cost is high, the difficulty in assembling the cup cover in the use process is even increased, and the normal use is influenced if the cup cover is not correctly assembled and the installation deviation occurs.

2. Because the power transmission assembly is arranged in the base positioned below the cup body, and the handle connected with the pull rope is arranged outside the base, when the base is placed on a table top or a workbench for use, the distance between the handle and the table top or the workbench is smaller, and no enough space is left for a user to operate the handle, so that the operation and the use are unchanged.

The lower side surface of the top cover 22 is further provided with a limiting rib 222, and the limiting rib 222 and the upper wheel plate 302 cooperate to form a spring mounting box for accommodating the clockwork spring 6. Therefore, one end of the spiral spring 6 is fixed on the fixing column 32, and then the spiral spring is wound on the driving wheel 3 in the second direction at the position center of the wheel shaft 31, and the other end is fixed on the limiting rib 222.

As further shown in connection with fig. 9. The shredding knife assembly 9 specifically comprises a knife holder 91, a knife rest 92, a plurality of shaft sleeves 93 and a plurality of blades 94; the two tail ends of the tool rest 92 are respectively provided with an upper shaft hole 921 and a lower shaft hole 922, and the upper shaft hole 921 is in transmission connection with the transmission shaft 42; each of the bushings 93 has a connecting shaft hole 931; the tail end of each blade 94 is provided with a limiting hole 941; the axle sleeve 93 is through connecting shaft hole 931 the blade 94 passes through spacing hole 941 cover is established blade holder 91, and the last end of blade holder 91 inserts down shaft hole 922, through the last end of blade holder 91 with interference fit links to each other or uses the fix with screw between the lower shaft hole 922. Therefore, the utility model discloses a chopper subassembly 9 adopts the combination to combine to make things convenient for the user to according to the actual need of edible material shredding in the cup 1 of cutting up comes the change as required the height of blade 94. For example, as shown in fig. 3, a lowermost one of the blades 94 is directly limited and fixed at a lowermost end of the blade seat 91 by a lowermost one of the bushings 93; as shown in fig. 4, the lowermost one of the blades 94 is formed by sleeving the lowermost end of the tool holder 91 with one of the bushings 93 and then sleeving the lowermost one of the blades 94, so that the lowermost one of the blades 94 shown in fig. 4 is higher than the lowermost one of the blades 94 shown in fig. 3 with respect to the bottom of the cutting cup 1.

In order to improve the stability of the chopper assembly 9 in the chopper cup 1, in one embodiment, a cup shaft 12 is disposed at the bottom of the chopper cup 1, a knife seat shaft hole 911 is disposed at the center of the lower end of the knife seat 91, the lower end of the chopper assembly 9 is disposed on the cup shaft 12 through the knife seat shaft hole 911, and the lower end of the chopper assembly 9 is limited by the cup shaft 12, so that the chopper assembly 9 is prevented from shaking or loosening greatly in the rotating process.
