Description

Technical Field

[0001] The invention relates to a small manual vegetable cutting tool, and more particularly to an inverted safety hand-pull vegetable cutter. Background Art

[0002] Hand-pull vegetable cutters have been widely popular among consumers in recent years due to their advantages of convenient operation and labor-saving. Existing hand-pull vegetable cutters chop block ingredients by rotating the blade assembly through a pull rope drive mechanism. They are mainly used for chopping block ingredients such as garlic, which can be completed by simply pulling the pull rope several times.

[0003] Existing hand-pull vegetable cutters all place the pull-cord drive mechanism in the upper cover, place the ingredients in the cup body, and cover the upper cover on the cup body to complete the assembly and cut the vegetables. For example, Chinese patent number ZL201821871614.7, the authorization announcement date is July 2, 2019, and the name of the invention is: a safe hand-pull vegetable cutter. The vegetable cutter in this application includes a cup body, a cup cover matching the cup body, a pull-cord drive mechanism installed in the cup cover, and a blade assembly located in the cup body and detachably connected to the driving end of the pull-cord drive mechanism. The bottom of the cup cover is provided with a skirt located on the periphery of the blade assembly to cover the blade assembly. The skirt is located on the inner side of the cup body when the cup body and the cup cover are combined, and the blade assembly remains on the cup cover when the cup body and the cup cover are opened. This patent application uses the skirt design to reduce the chance of users contacting the blade and improve the safety of the vegetable cutter. It is not difficult to find that the operation process of the above-mentioned existing hand-pull type vegetable cutter is to open the cup cover, then add food into the cup body or the inverted cup cover, then assemble the cup body and the cup cover together, put the vegetable cutter upright and then cut it by hand. In this operation process, even with the protection of the skirt, the blade assembly is exposed, and in the process of adding food into the inverted cup cover, the food is easy to slide out under the obstruction of the blade assembly, and if the food is directly added into the cup body, in the process of covering the cup cover, the food in the cup body is also easy to block the blade assembly, making it difficult to assemble the cup cover and the cup body.

[0004] It can be seen that the existing hand-pull vegetable cutter still has the following problems to be solved:

[0005] 1. During the process of adding and pouring out food, after the cup body and the cup cover are opened, the blade assembly is easily exposed, which may cause hand injuries and other safety hazards. In addition, the operation of adding and pouring out food is inconvenient, and it is easy for food to roll out or the assembly of the vegetable cutter is inconvenient.

[0006] Second, although the existing hand-pull vegetable cutters are designed to be relatively small and convenient to grasp and operate, they are still prone to slipping during the hand-pull operation because their appearance is designed to be relatively round. Summary of the invention

[0007] 1. Technical problem to be solved by the invention

[0008] One object of the present invention is to overcome the shortcomings of the existing hand-pull vegetable cutter, such as the inconvenience of adding and pouring out ingredients and the easy contact with the blade during the operation, and to provide an inverted safe hand-pull vegetable cutter. The technical solution of the present invention is adopted, the vegetable cutter is arranged in an inverted structure, and an inlet is provided at the top of the cup body. Ingredients are added through the inlet at the upper part, and the ingredients are directly poured out from the inlet after being chopped. Compared with the existing hand-pull vegetable cutter, the operation is more flexible and convenient, the addition and pouring of ingredients are more accurate and stable, and the ingredients are not easy to spill. Moreover, the blade does not need to be touched during the entire operation process, and the operation is safer.

[0009] Another purpose of the present invention is to solve the problem that the existing hand-pull vegetable cutter is inconvenient to grip and easy to slip. The vegetable cutter is set upside down and a neck section is provided on the upper part of the cup body. The neck section on the upper part of the cup body is used as the grip of the vegetable cutter. The base of the fingers can just grip the neck section of the cup body.

DETAILED DESCRIPTION

[0046] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0047] [Example 1]

[0048] Combination Figure 1 , Figure 2 and Figure 3As shown, an inverted safe hand-pull vegetable cutter of this embodiment comprises a base 1, a cup body 2 detachably connected to the base 1, a pull rope drive mechanism 3 installed in the base 1, and a blade assembly 4 located in the cup body 2 and axially connected to the output shaft 3-2 of the pull rope drive mechanism 3. The upper end of the blade assembly 4 is axially rotated and positioned with the cup body 2 through a positioning column 2-3 provided on the upper part of the cup body 2. The pull rope drive mechanism 3 can be used to drive the blade assembly 4 in the cup body 2 to rotate rapidly and chop the food in it. The structure and principle of the pull rope drive mechanism 3 are similar to those of the existing hand-pull vegetable cutter. The pull rope is driven by the handle 3-1 on the outside of the base 1 to drive the output shaft 3-2 to rotate. The pull rope rewinding mechanism, the speed increasing gear train and the one-way output mechanism inside the pull rope drive mechanism 3 are used to achieve the one-way high-speed rotation of the output shaft 3-2, thereby driving the blade assembly 4 to rotate to cut the food. Unlike the existing hand-pull vegetable cutter, the safe hand-pull vegetable cutter of this embodiment adopts an inverted design, that is, the pull rope drive mechanism 3 is arranged at the bottom of the entire hand-pull vegetable cutter, the cup body 2 is located on the upper part, and there is an inlet 2-2 at the top of the cup body 2, and an upper cover 5 is provided at the inlet 2-2. The upper cover 5 can be removed from the inlet 2-2 to block the inlet 2-2 when cutting vegetables. Food materials are added from the inlet 2-2 and chopped in an inverted manner. After chopped, the upper cover 5 is opened. Since the blade assembly 4 is located between the base 1 and the cup body 2, the chopped food materials can be poured out directly from the inlet 2-2. Compared with the existing hand-pull vegetable cutter, the operation is more flexible and convenient, the addition and pouring of food materials are more accurate and stable, and it is not easy to spill. In addition, there is no need to touch the blade during the entire operation process, and the operation is safer.

[0049] In this embodiment, the cup body 2 can adopt a straight cylindrical structure with upper and lower openings. The positioning column 2-3 is set at the center of the cup body 2 through a positioning bracket 2-5 on the upper part of the cup body 2. The positioning bracket 2-5 can adopt a cantilever bracket, a multi-frame bracket, etc. In order to take into account the strength of the bracket and facilitate the introduction or pouring of food, the positioning bracket 2-5 preferably adopts a beam placed horizontally below the upper inlet 2-2 of the cup body 2, and the positioning column 2-3 is located at the center of the beam. In order to better grasp the main body of the vegetable cutter for operation, in this embodiment, preferably, a necking section 2-1 is provided on the upper part of the cup body 2, and the inlet 2-2 is provided at the top of the necking section 2-1. Since the diameter of the necking section 2-1 is smaller than the diameter of the lower part of the cup body 2, therefore, on the basis of the inverted arrangement of the vegetable cutter, the necking section 2-1 on the upper part of the cup body 2 is used as the grip of the vegetable cutter, and the base of the fingers can just hold the necking section of the cup body 2, so that the vegetable cutter is more reliably grasped and not easy to slip, further improving the reliability and safety of the operation.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the necking section 2-1 is arranged toward one side of the cup body 2, and the necking section 2-1 gradually shrinks upward from the middle of the cup body 2 toward one side, and can be appropriately expanded outward at the input port 2-2, which is not only convenient for grasping the necking section 2-1, but also because the necking section 2-1 is located at one side of the cup body 2, the positioning column 2-3 can be directly arranged at the center of the inner wall of the necking section 2-1, and there is no need to arrange the positioning bracket 2-5, and there is no shielding at the input port 2-2, which is convenient for adding and pouring food. In addition, the handle 3-1 of the pull rope drive mechanism 3 is arranged at one side of the base 1. When the necking section 2-1 is arranged toward one side of the cup body 2, after the cup body 2 is assembled on the base 1, the necking section 2-1 is arranged on the side away from the handle 3-1 on the cup body 2. This arrangement avoids interference between the necking section 2-1 and the handle 3-1 after grasping, so that the hand-pull operation of the vegetable cutter is more in line with people's operating habits and improves the convenience of operation. The cup body 2 is integrally formed, and the size of the input port 2-2 at the top of the necked section 2-1 can be slightly enlarged outwards to facilitate the input of food. The cup body 2 is preferably made of transparent or translucent material so that the chopped food can be observed at any time.

[0051] like Figure 2 and Figure 4 As shown, in this embodiment, the lower part of the blade assembly 4 is also provided with a scraper 4-5 that matches the upper plane of the base 1. The scraper 4-5 can be provided with one or more scrapers along the circumference. The scraper 4-5 can be integrally formed on the bottom of the knife seat 4-2. The scraper 4-5 can be designed as a flat structure. With the design of the scraper 4-5, on the one hand, during the vegetable cutting process, the scraper 4-5 rotates with the blade assembly 4, which can help to roll the food, so that the food can be chopped more evenly and quickly. On the other hand, when pouring out the food, the handle 3-1 can be gently pulled to use the scraper 4-5 to scrape off the food stuck to the bottom, so that the cut food can be quickly poured out and the food waste can be reduced. Figure 2 and Figure 3As shown, in order to prevent the juice produced by cutting vegetables from leaking out or contaminating the vegetable cutter, an outer skirt 1-1 located on the inner side of the cup body 2 is provided on the upper outer side of the base 1, and a raised platform 1-2 is provided at the upper center of the base 1. The outer skirt 1-1 and the raised platform 1-2 form an annular cavity on the upper part of the base 1, which effectively prevents the juice from cutting vegetables from flowing out or flowing into the pull-cord drive mechanism inside the base, ensuring the cleanliness and hygiene of the vegetable cutter during use. In addition, when the cup body 2 is removed from the base 1 for cleaning, the blade assembly 4 is blocked by the outer skirt 1-1, and the base 1 can be rinsed without touching the blade, and the rinsing process is also safer; at the same time, the blade assembly 4 can also be removed for separate cleaning and replacement. In order to prevent the food from rotating with the blade assembly 4, a plurality of anti-rotation ribs 1-3 are provided on the inner side of the outer skirt 1-1. The anti-rotation ribs 1-3 are vertically integrated on the inner side of the outer skirt 1-1. Preferably, a plurality of anti-rotation ribs 1-3 are provided at intervals on the inner side of the outer skirt 1-1. The anti-rotation ribs 1-3 can effectively prevent the food from rotating with the blade, thereby improving the cutting efficiency of the vegetable cutter. When operating, the food can be chopped by simply pulling the handle repeatedly a few times.

[0052] catch Figure 2 and Figure 3 As shown, in order to facilitate the installation of the blade assembly 4, in this embodiment, the upper part of the blade assembly 4 is provided with a positioning installation hole 4-1-2 which is axially rotated with the above-mentioned positioning column 2-3, the positioning column 2-3 is a cylindrical structure, and the positioning installation hole 4-1-2 is a circular hole adapted to the positioning column 2-3, so that the blade assembly 4 can rotate stably; the lower part of the blade assembly 4 is provided with a plug-in hole which is sleeved on the elevated platform 1-2 and axially transmittance-coordinated with the output shaft 3-2 of the pull-wire drive mechanism 3, the cross-sectional shape of the plug-in hole is adapted to the cross-sectional shape of the output shaft 3-2, and the cross-sectional shape of the output shaft 3-2 preferably adopts a regular polygonal structure, such as Figure 2 As shown in the regular quadrilateral, the insertion hole of the blade assembly 4 is inserted into the output shaft 3-2 to realize power transmission. With the above-mentioned positioning structure, the disassembly and assembly of the blade assembly 4 is more convenient, the transmission efficiency of the pull rope drive mechanism 3 to the blade assembly 4 is higher, and the rotation of the blade assembly 4 is more stable and reliable. Moreover, in this embodiment, the upper part of the blade assembly 4 is a conical structure with a large lower end and a small upper end, and an inclined guiding effect is formed at the necking section 2-1, which is not easy to block the addition or pouring of food, ensuring that the food can smoothly slide into the bottom of the vegetable cutter and be chopped. Further, as Figure 3 and Figure 4As shown, the above-mentioned blade assembly 4 includes a pressure cap 4-1, a blade seat 4-2, a spacer sleeve 4-3 and a blade 4-4. A blade limiting boss 4-2-1 is provided at the bottom of the blade seat 4-2. The spacer sleeve 4-3 is sleeved on the blade seat 4-2. The pressure cap 4-1 is fixedly connected to the upper part of the blade seat 4-2. The blade 4-4 is at least arranged at the upper and lower ends of the spacer sleeve 4-3. The blade 4-4 is pressed and fixed by the blade seat 4-2, the spacer sleeve 4-3 and the pressure cap 4-1. The positioning installation hole 4-1-2 is provided at the upper part of the pressure cap 4-1, and the plug-in hole is provided at the lower part of the blade seat 4-2. Specifically, two blades 4-4 are provided, and the two blades 4-4 have the same structure. A blade mounting hole 4-4-1 is provided on the blade 4-4, and a blade positioning groove 4-4-2 is provided on one side of the blade mounting hole 4-4-1. The blade 4-4 located at the lower portion is installed on the blade seat 4-2 through the blade mounting hole 4-4-1, and a blade seat anti-rotation boss 4-2-2 which is positioned and matched with the blade positioning groove 4-4-2 of the blade 4-4 is provided on the blade limiting boss 4-2-1; a blade mounting portion 4-1-1 is provided at the lower end of the pressure cap 4-1, and the blade 4-4 located at the lower portion is installed on the blade mounting portion 4-1-1 through the blade mounting hole 4-4-1, and a pressure cap anti-rotation boss 4-1-3 is provided on one side of the blade mounting portion 4-1-1. The height of the blade holder anti-rotation boss 4-2-2 and the pressure cap anti-rotation boss 4-1-3 is greater than the thickness of the blade 4-4. Anti-rotation positioning grooves 4-3-1 that match the above-mentioned blade holder anti-rotation boss 4-2-2 and the pressure cap anti-rotation boss 4-1-3 are provided at the corresponding positions of the upper and lower ends of the spacer 4-3. The pressure cap 4-1 and the blade holder 4-2 can be fixedly connected by axially arranged screws. With the above-mentioned blade assembly 4, the manufacture of the blade assembly 4 is simple and convenient, and the blade is firmly and reliably fixed; and after the plug-in hole at the lower part of the blade assembly 4 is matched with the heightening platform 1-2, the heightening platform 1-2 forms an "n"-shaped rotating sealing structure with the blade assembly 4 and the output shaft 3-2 of the pull rope drive mechanism 3, further preventing the cutting juice from penetrating into the base 1. For the installation of more than two blades, the spacer 4-3 can be designed as multiple sections, and blades 4-4 can be arranged between two adjacent sections of the spacer 4-3. Each blade 4- is installed at a certain distance in the axial direction and is evenly distributed in the circumference in the circumferential direction. The conical structure on the upper part of the blade assembly 4 is formed by the pressing cap 4 - 1 , and the pressing cap 4 - 1 can be designed as an umbrella-shaped structure.

[0053] like Figure 3As shown, the above-mentioned base 1 includes a lower shell 1a and an upper shell 1b. The upper shell 1b is fixedly connected to the lower shell 1a. A cavity 1c for installing the pull-cord drive mechanism 3 is formed between the upper shell 1b and the lower shell 1a. The upper shell 1b and the lower shell 1a can be fixedly connected by a snap-fit ​​structure. The pull-cord drive mechanism 3 is the same as the existing hand-pull vegetable cutter in terms of specific structure and will not be described in detail again. The pull cord of the pull-cord drive mechanism 3 extends out of one side of the lower shell 1a and is fixedly connected to the handle 3-1. The outer skirt 1-1 and the elevated platform 1-2 are both integrally formed on the upper part of the upper shell 1b. The upper and lower shell designs facilitate the installation of the pull-cord drive mechanism 3, and the assembly is simple and convenient. The lower end of the cup body 2 is connected to the upper shell 1b by a threaded connection or a rotating snap-fit ​​mechanism. The cup body 2 is easy to disassemble and assemble on the base 1. After the cup body 2 is removed, it is convenient to thoroughly clean the entire vegetable cutter and disassemble and replace the blade assembly 4. Figure 2 and Figure 5 As shown, in this embodiment, the lower end of the cup body 2 is connected to the upper shell 1b by a rotating locking mechanism, that is, a plurality of blocks 2-4 are provided on the inner side wall of the lower end of the cup body 2, and a slot 1-4 matching the blocks 2-4 is provided on the outer side of the base 1. When the cup body 2 and the base 1 are assembled, after the cup body 2 is buckled on the base 1, the cup body 2 is rotated clockwise to snap the blocks 2-4 into the slot 1-4, so as to realize the connection between the cup body 2 and the base 1. The disassembly process only requires the cup body 2 to be rotated in the opposite direction. In order to improve the connection stability between the cup body 2 and the base 1, a protrusion can be provided at the entrance of the slot 1-4, and after the block 2-4 is screwed into the slot 1-4, the block 2-4 is limited by the protrusion.

[0054] Combination Figure 6 As shown, in this embodiment, the shape of the upper cover 5 is adapted to the shape of the input port 2-2 of the necking section 2-1, and a circle of cover grooves 5-2 matching the input port 2-2 of the necking section 2-1 are provided on the outer periphery of the upper cover 5, and the upper cover 5 is sealed and buckled on the side edge of the input port 2-2 through the cover grooves 5-2, and a lug 5-1 is provided on one side of the upper cover 5. The upper cover 5 can be made of soft materials such as food-grade silicone, and the cover is stably and reliably placed, and the lug 5-1 is used to facilitate the removal of the upper cover 5, and the operation is flexible and convenient.

[0055] [Example 2]

[0056] See also Figures 7 to 10As shown, an inverted safety hand-pull vegetable cutter of this embodiment has the same basic structure and use principle as that of embodiment 1, except that: in this embodiment, the necking section 2-1 is arranged at the middle position of the upper part of the cup body 2, that is, the input port 2-2 is located at the center position of the cup body 2. In order to facilitate the setting of the positioning column 2-3, a positioning bracket 2-5 is arranged at the upper part of the necking section 2-1, and the positioning column 2-3 is arranged at the center position of the cup body 2 by using the positioning bracket 2-5. The above-mentioned positioning bracket 2-5 preferably adopts an "S"-shaped beam spanning the upper part of the necking section 2-1, and the positioning column 2-3 is arranged at the center of the positioning bracket 2-5 extending downward. Of course, the necking section 2-1 can also deviate slightly from the center position to one side relative to the cup body 2, and it is only necessary to ensure that the position of the positioning column 2-3 can be matched with the upper axial rotation positioning of the blade assembly 4 on the base 1. Compared with embodiment 1, the input port 2-2 of the necking section 2-1 in this embodiment can be set larger, but the disadvantage is that the positioning bracket 2-5 needs to be set.

[0057] Another variation of this embodiment is to design the inner diameter of the neck section 2 - 1 to be the same as that of the cup body 2 , that is, to form a straight cylindrical cup body structure that is consistent from top to bottom.

[0058] The inverted safe hand-pull vegetable cutter of the above-mentioned embodiment 1 and embodiment 2 solves the two major technical problems of the existing hand-pull vegetable cutter, namely, the inconvenience of adding and pouring out ingredients, the potential safety hazard, and the poor grip reliability of the main part of the vegetable cutter, by setting the vegetable cutter upside down. It provides a new design idea for the safe and flexible operation of the hand-pull vegetable cutter, and the vegetable cutter has a simple and compact structural design, a novel appearance, and is flexible and convenient to operate. Figure 1 and Figure 3 , Figure 7 and Fig. 9As shown, when in use, the upper cover 5 is opened, and block-shaped food such as garlic is added from the inlet 2-2 of the neck section 2-1 of the cup body 2. The food enters the bottom of the cup body 2 along the neck section 2-1. It is not easy for the food to overflow during the adding process. The hand-pull vegetable cutter can be properly shaken during the adding process. After the food is added, the upper cover 5 is closed, and then the neck section 2-1 is held by the thumb and the other four fingers of one hand, and the main part of the vegetable cutter is held by the thumb and the other four fingers, and then the handle 3-1 is repeatedly pulled several times with the other hand. , the pull rope driving mechanism 3 drives the blade assembly 4 in the cup body 2 to rotate to chop the food. During the chopping process, the scraper 4-5 is used to turn up the food at the bottom to make the food chopped more evenly. The chopping of the food can be observed through the transparent or translucent cup body 2; after the food is chopped, open the upper cover 5 and pour the food out from the input port 2-2. During the pouring process, the handle 3-1 can be pulled a few times to use the scraper 4-5 to scrape off the food stuck to the bottom, making it easier to pour out the food. When cleaning, the upper cover 5 can be directly opened and the input port 2-2 can be rinsed against the faucet without touching the blade; the cup body 2 can also be removed from the base 1, and the blade assembly 4 can be removed for thorough cleaning, and then dried.

[0059] The inverted safe hand-pull vegetable cutter of the present invention adopts an inverted structure. Ingredients are added through an input port at the top. After the ingredients are chopped, they are directly poured out from the input port. Compared with the existing hand-pull vegetable cutter, the operation is more flexible and convenient, and the addition and pouring of ingredients are more accurate and stable, and not easy to spill. Moreover, there is no need to touch the blade during the entire operation process, so the operation is safer. In addition, by setting the vegetable cutter upside down, the neck section at the top of the cup body is used as the grip of the vegetable cutter, and the base of the fingers can just grip the neck section of the cup body. Compared with the existing hand-pull vegetable cutter, the vegetable cutter can be gripped more reliably and is not easy to slip, thereby further improving the reliability and safety of the operation.
