DETAILED DESCRIPTION OF THE EMBODIMENTS

A detailed description of the present disclosure is provided with reference to the accompanying drawings and examples to facilitate the understanding of the present disclosure.

Examples

As shown inFIGS.1to5, a safe hand-pulled vegetable chopper of the embodiment includes a cup body1, a lid that matched with the cup body1, a puller cord driving member3provided in the lid2, and a blade assembly4in the cup body1and detachably connected to a driving end of the puller cord driving member3. The puller cord driving member3is connected with the handle7through the puller cord, a user pulls the handle7to rotate the puller cord driving member3through the puller cord, and then the blade assembly4is rotated to chop the food in the cup body1; with a cord rewinding member and a one-way output member in the puller cord driving member3, the user pulls the handle7repeatedly and then ingredients can be easily chopped into pieces. Different from the prior art, a circular skirt-like enclosure5is provided from a bottom of the lid2around an outer periphery of the blade assembly4to shield the blade assembly4. The skirt-like enclosure5is within the cup body1when the cup body1and the lid2are engaged, the blade assembly4stays on the lid2when the cup body1and the lid2are separated. With the above-mentioned structural design, when the cup body1and the lid2are separated, the blade assembly4stays on the lid2and is shielded by the skirt-like enclosure5. If the user has solid ingredients to be chopped, all that he/she has to do is to put the ingredients into the skirt-like enclosure5of the lid2and then close with the cup body1; after the chopping is complete, the lid2is opened, the blade assembly4stays on the lid2, and the ingredients in the cup body1can be directly taken out for use; when whipping up liquid ingredients such as eggs, all that the user has to do is to put the ingredients into the cup body1for whipping up; when cleaning, the user can simply rinse the cup body1and the lid2provided with the blade assembly4, and then fill the cup body1with clean water and close the lid2, shake and pull the handle7to clean the blade assembly4, the cup body1, and the lid2. It can be seen from the above-mentioned process that the blade assembly4stays on one side of the lid2and is shielded by the skirt-like enclosure5after the vegetable chopper is opened, the user is less likely to contact the blade and the safety of the vegetable chopper is improved; the user can put solid ingredients directly into the interior of the lid2enclosed by the skirt-like enclosure5, and then assemble the cup body1on the lid2, without aligning the blade assembly4and the lid2, which facilitates the assembling of the vegetable chopper, ensures the convenience and safety in the process of the vegetable chopping, and enables a flexible user experience and convenient rinse of the vegetable chopper. Besides, as shown inFIG.5, to improve the efficiency of the vegetable chopper, a plurality of splines5-4are also provided on the inner side of the skirt-like enclosure5. The use of the splines5-4effectively prevents the ingredients from rotating with the blade and improves the efficiency of the vegetable chopper. As shown inFIGS.2to4, as a preferred embodiment, the skirt-like enclosure5is attached to the inner sidewall of the cup body1, and the skirt-like enclosure5is provided with a plurality of notches5-1at intervals, and the notches5-1divide the skirt-like enclosure5into several tabs; with the above-mentioned notches5-1, if the cup body1is transparent, to which a degree the ingredients are being chopped can be observed through the notches5-1, and the convenience in use is improved; of course, the cup body1can also be designed to be translucent or opaque. To improve the anti-slip performance of the vegetable chopper, an anti-slip pad1-2is also provided at the bottom of the cup body1. Preferably, the splines5-4are arranged on the same sides of opening walls of the notches5-1(shown inFIG.5), which not only facilitates the forming of the splines5-4on the skirt-like enclosure5, but reinforces the effect of stopping rotating along with the blades by the splines with the help of the opening walls of the notches, hence the efficiency of chopping is improved. Besides, the notch5-1is semi-closed by the stopper edge5-2at the top of the skirt-like enclosure, and the notch5-1is open at the bottom, as such, small-grain ingredients can be prevented from leaking out of the notch5-1when ingredients are fed into the skirt-like enclosure5, and space can be reserved to observe to which a degree the ingredients are being chopped, thereby enabling a more flexible and convenient user experience. As shown inFIGS.4and5, in this embodiment, preferably three groups of the notches5-1are uniformly arranged on the skirt-like enclosure5. The cup body1and the lid2are rotated to engage. An outer sidewall of the skirt-like enclosure5is further provided with snap slots5-3, and the inner sidewall of the cup body1is provided with snap fasteners1-3matched with the snap slots5-3, and the snap fastener1-3is snapped into the snap slot5-3by rotating the skirt-like enclosure5relative to the cup body1, as such, it's easy and convenient to assemble and disassemble the cup body1and the lid2; also, three groups of the snap fasteners1-3and the snap slots5-3are provided correspondingly, which improves the stability of the engagement between the cup body1and the lid2. Besides, in the safe hand-held vegetable chopper of this embodiment, the blade assembly4is magnetically attracted to the driving end of the puller cord driving member3, so that the blade assembly4can stay on one side of the lid when the vegetable chopper is opened. The chopped ingredients in the cup body1can be directly taken out for use without removing the blade assembly4, and the blade assembly4is fixed magnetically, which facilitates the disassembling and assembling thereof and enables a quick replacement of the blade assembly4. The blade assembly4in this embodiment includes a blade mount4-1and blades4-2mounted on the blade mount4-1. The blade mount4-1can be specifically composed of three parts as shown inFIGS.2and3, such a three-part configuration enables the mounting of two blades4-2and facilitates replacement of the blades. An upper end of the blade mount4-1is provided with a jack4-1-1for mating and in transmission connection with the driving end of the puller cord driving member3, and the lower end of the blade mount4-1is provided with a positioning hole4-1-2for mating a positioning column1-1at the bottom of the cup body1, which ensures that the blade mount4-1can be in stable transmission connection with the driving end of the puller cord driving member3, so that the rotation of the blade assembly4is more stable and reliable. As shown inFIG.2, the lid2in this embodiment includes an upper lid2-1and a lower lid2-2provided at a bottom of the upper lid2-1. The upper lid2-1and the lower lid2-2are fixedly connected. A cavity is formed between the upper lid2-1and the lower lid2-2, and the skirt-like enclosure5is integrally formed at a bottom of the lower lid2-2to facilitate the forming of the skirt-like enclosure5. For the user to better grasp the vegetable chopper, anti-skid patterns can be designed on an outer surface of the upper lid2-1. The specific structure of the puller cord driving member3in this embodiment is similar to that in the prior art, and the puller cord driving member3is installed in the cavity formed by the upper lid2-1and the lower lid2-2. As shown inFIG.6, the puller cord driving member3includes a torsion spring3-1, a cord reel3-2, pawls3-3, and a ratchet gear wheel3-4. The cord reel3-2is sleeved on a central column of the upper lid2-1and can rotate freely on the central column of the upper lid2-1, the puller cord is provided in a middle cord groove of the cord reel3-2, and one end of the puller cord is connected with the handle7provided on an outer side of the lid2. An upper part of the cord reel3-2is provided with the torsion spring3-1. An inner connecting end of the torsion spring3-1is connected to the cord reel3-2, and an outer connecting end is connected to the upper lid2-1. A lower part of the cord reel3-2is provided with the pawls3-3. The pawls3-3are mounted on a mounting pin3-2-1at the bottom of the cord reel3-2and are matched with the ratchet gear wheel3-4on the lower lid2-2, a circle of ratchet teeth is provided on an inner side of the ratchet gear wheel3-4, the pawls3-3are unidirectionally geared with the ratchet gear wheel3-4, and a connecting column3-4-1penetrating through the lower lid2-2is provided at a center of the ratchet gear wheel3-4. When the handle7is pulled, the puller cord rotates the cord reel3-2. At this time, the pawl3-3is geared with the ratchet gear wheel3-4to rotate the ratchet gear wheel3-4, and then the connecting column3-4-1drives the blade assembly4to rotate to chop the ingredients, while the torsion spring3-1tightens; when the handle7is released, the torsion spring3-1is released to rotate the cord reel3-2in a reverse direction, and the puller cord is rewound into the cord groove, at this time, the pawl3-3disengages from the ratchet gear plate3-4, and the ratchet gear plate3-4will not reverse with the cord reel3-2; the user can pull the handle7back and forth to drive the blade assembly4to rotate unidirectionally and chop the ingredients. Of course, other similar unidirectional driving members can serve as the puller cord driving member3. The above-mentioned connecting column3-4-1is provided with a magnetic block6for attracting a ferromagnetic component in the jack4-1-1; for example, a magnet is embedded in the connecting column3-4-1, screws are provided in the jack4-1-1, and the blade assembly4is connected with the driving end of the cord drive member3through the attraction between the magnet and the screws; to increase the magnetic attraction, both the connecting column3-4-1and the jack4-1-1can be provided with a magnet; of course, it is also possible to provide a magnet in the jack4-1-1and embed an iron block in the connecting column3-4-1. According to the safe hand-pulled vegetable chopper of this embodiment, the user can rotate the lid2counterclockwise to open the lid2. At this time, the blade assembly4is connected to the lid2. if the user has solid ingredients to chop, he/she can place the lid2upside down, put the ingredients directly into the skirt-like enclosure5of the lid2, close with the cup body1, and rotate the lid2in a reverse direction to engage the lid2and the cup body1; after this, the user can hold the vegetable chopper with one hand, pull the handle7with the other hand to drive rotate the blade assembly4to quickly rotate and chop the ingredients.
