Description

Screw, food processing cup and food processor

Technical Field

The invention relates to the field of household appliances, in particular to a screw, a food processing cup and a food processor.

Background

At present, the screw rod of stock machine is made by plastics more, and the screw rod is at the course of the work, need extrude the edible material with the cup of squeezing the juice together, especially the lower extreme of screw rod and the clearance between the cup of squeezing the juice of food processor are less, therefore, the lower extreme wearing and tearing of screw rod are very serious, thereby can influence the life of screw rod, and simultaneously, the screw rod wearing and tearing can drop some granules, and these granules that drop can pollute the food of processing, harm user's health, the in-process of screw rod processing food in addition, the pigment of food itself can dye the screw rod, thereby can lead to the difficult washing of screw rod, reduce the aesthetic property of screw rod.

Therefore, how to design a screw rod which is wear-resistant, clean to use, free of pollution to food and low in cost becomes a problem to be solved urgently at present.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art.

To this end, it is an object of the present invention to provide a screw.

It is a further object of the present invention to provide a food processing cup.

Another object of the present invention is to provide a food processor comprising the above food processing cup.

To achieve the above object, an embodiment of a first aspect of the present invention provides a screw for a food processor, specifically, the screw includes: the cross-sectional area of the screw rod body is increased from one end of the screw rod body, which is far away from the installation cavity, to one end of the screw rod body, which is close to the installation cavity; the wear-resistant part is arranged on the outer surface of the screw rod body; the filling shell is arranged between the screw rod body and the wear-resistant part; wherein, fill the casing and pass through injection moulding, the screw rod body fill the casing with wearing parts formula structure as an organic whole.

The screw provided by the embodiment of the invention comprises a screw body, a wear-resistant part and a filling shell filled between the screw body and the wear-resistant part, wherein the filling shell is formed by injection molding, namely when the screw is specifically processed, the wear-resistant part and the screw body are firstly placed in a mold cavity, and then the filling shell is injected between the wear-resistant part and the screw body, so that the wear-resistant part and the screw body can be connected into an integrated structure by the filling shell. This kind of structure, because the mode that the casing was filled in the accessible was moulded plastics realizes the installation between wearing parts and the screw rod body, consequently, can make wearing parts connect more firm on the one hand, on the other hand does not need additionally to set up other connection structure, therefore can make the structure of the screw rod of final processing simpler, can reduce the processing cost of screw rod again. And through set up the wearing parts on the screw rod body, can come the inner wall of the cup of screw rod and food processing cup to keep apart each other through the wearing parts to reducible screw rod and food processor's the friction between the juice cup, and then can reduce the wearing and tearing of screw rod when the screw rod rotates, in order to solve the problem of the easy wearing and tearing damage of screw rod. According to the structure, on one hand, the abrasion of the screw rod during single use is reduced, so that after the product is used for a long time, the screw rod cannot be abraded seriously, the performance of the product cannot be reduced due to the abrasion of the screw rod, and the product can still have better performance after being used for a long time. On the other hand, the abrasion of the screw is reduced, so that particles falling off due to the abrasion of the screw can be reduced, the situation that processed food is polluted by the particles falling off due to the abrasion of the screw can be prevented, the health of consumers is damaged, and the cleanness and the sanitation of the food can be ensured. In addition, can also protect the surface of screw rod through setting up the wearing parts to can prevent that the screw rod from being dyed by the pigment of food itself at the course of the work, and then make the screw rod change and wash, can keep the clean and tidy degree of screw rod after long-term the use again, and then can ensure the aesthetic property of screw rod and cooking machine for a long time. And through set up one end confined transmission hole on the screw rod body, blind hole promptly to can be with a connecting axle disect insertion transmission downthehole, in order to realize the drive to the screw rod, and through setting up the transmission hole, can replace the screw rod axle through the transmission hole, and then can cancel the screw rod axle, when cup is handled to concrete equipment food like this, can install the connecting axle in the mounting hole of cup earlier, then install the upper end at the connecting axle with the screw rod, alright handle cup monolithic mount on the base with food afterwards. This kind of mounting means, because screw rod and connecting axle are split type structure, consequently, can carry out the installation of connecting axle earlier, then install sealing silica gel, screw rod etc. on the connecting axle in proper order, consequently, in the installation of screw rod, the screw rod can not receive the hindrance of sealing silica gel etc. consequently, can realize food processing cup's equipment smoothly, fast and laborsavingly, and then can improve the installation and experience. In addition, the structure of the screw can be simplified because the screw shaft is not arranged, thereby not only reducing the volume of the screw to be convenient for transportation and storage, but also reducing the processing cost of the screw to reduce the total cost of products. In addition, can set the lower extreme of the screw rod body to hollow installation cavity, thereby just can be more close to the top setting of the screw rod body with the transmission hole, when utilizing the cooperation of connecting axle and transmission hole to drive the screw rod and rotate like this, can stretch into the connecting axle as far as possible to the screw rod is internal, therefore the connecting axle can drive with the position that the screw rod body is more close to the well upper portion of screw rod and be connected, just so can be close to the focus setting of screw rod with the drive position of screw rod and connecting axle, thereby just can ensure the stability after the screw rod installation, and then can prevent that the screw rod from rocking in the course of the work, therefore can reduce the screw rod because of rocking and the friction that the cup of squeezing the juice takes place promptly, thereby can further reduce the wearing and tearing of product. On the other hand sets the lower extreme through with the screw rod body to cavity, can also set up a boss on the diapire of the juice extraction cup of food processor to when the installation screw rod, can stretch into the boss in the lower extreme of the screw rod body, in order to realize the location installation to the screw rod, therefore can improve the installation rate and the installation convenience of screw rod. In addition, the lower end of the screw rod body is arranged to be hollow, so that the screw rod can be vertically and stably placed on a desktop or a cooking bench and the like, and the situation that the screw rod rolls on the desktop or the cooking bench and the like can be prevented.

Wherein, the cross-sectional area of the screw rod body is kept away from the one end of installation cavity to the one end that the screw rod body is close to the installation cavity increase from the screw rod body for the screw rod can be from last to increasing down, can set up the screw rod roughly to be conical promptly, when installing the screw rod in the cup of food processor like this, just can make the clearance between the inside wall of screw rod and cup reduce from last to down, therefore just can handle the edible material from last to down more garrulous, and then can improve the treatment effect of screw rod to eating the material, in order to improve juice yield.
