TECHNICAL FIELD
The present disclosure relates to a vegetable chopper, and more particularly, to a safe hand-pulled vegetable chopper.
BACKGROUND ART
At present, most of the common manual vegetable choppers in the market are operated by rotating a crank manually or scraping ingredients against a blade reciprocatively. These vegetable choppers are simple and easy to use but have disadvantages such as low efficiency and laborious operation. To overcome the shortcomings of the above-mentioned vegetable choppers, a hand-pulled vegetable chopper is also available in the market, such as the one disclosed in the Chinese patent No. ZL200920311434.8, granted on Sep. 8, 2010, titled “A Puller Cord Vegetable Chopper”, and relating to a puller cord vegetable chopper that includes a container, a lid assembly that covers the container, and a blade mount assembly connected to the lid assembly; wherein the lid assembly has a lid, a puller cord rewinding member, a speed-increasing gear train connected to the puller cord rewinding member, and a one-way output member connected to the speed-increasing gear train; the blade mount assembly includes a blade mount, and blades mounted on the blade mount. With such a puller cord vegetable chopper, a user can pull the cord to drive the blade to rotate and chop the ingredients, which is labor-saving and efficient.
The hand-pulled vegetable chopper has been widely favored by consumers in recent years because of its advantages of being labor-saving and efficient. Those skilled in the art have also optimized the “hand-pulled vegetable chopper”. For example, the Chinese patent No. ZL201620729905.7 discloses a “Hand-pulled Rotary Chopper”, where a novel one-way output member is provided to replace that of the old one, and a hand-pulled transmission member of the vegetable chopper is simplified. The Chinese patent application No. 201610090733.8 discloses a “Double-chamber Food Processor Driven by Puller Cord”, where two chopping chambers are provided as an upgrade based on the old one, which solves the problem of the existing puller cord food processor that only one kind of food or a mixture of several foods can be processed but two separate foods cannot be processed at the same time. The Chinese patent No. ZL201721240776.6 discloses a “Manual Vegetable Chopper”, where a gear structure is used to drive the cord to chop food, which requires a gentler force and reduces the friction among parts in the entire internal rotatory structure, labor-saving and efficient, and greatly avoids jamming the cord.
However, the blade assembly of the hand-pulled vegetable chopper in the prior art stays in the cup body after the lid is opened, the user has to remove the blade assembly before taking out ingredients or cleaning the cup body, it's thus very likely for the user to contact the blade and get hurt, and it's found that these accidents often occur, which constitutes a severe safety issue; moreover, because the blade assembly stays in the cup body, it's difficult for a user to align the blade assembly and the lid when assembling the vegetable chopper, which can be troublesome. No effective solution has been found yet to the above-mentioned safety and assembly problems.
