Description

Technical Field

[0001] The utility model relates to the technical field of daily life tools, in particular to a button trimming can opener. Background Art

[0002] In daily life, there are many varieties of canned foods, most of which are packaged in tinplate cans. To consume these canned foods, a blade is required to cut the lid open to remove the food. Consequently, a wide variety of can openers have emerged on the market, with two main categories: single-handle and double-handle. Currently, these can openers typically feature a drive cone rod equipped with teeth. During can opening, the teeth of the drive cone rod engage the lid, creating a tooth mark. This tooth mark generates significant friction, which, when rotated, drives the lid to rotate, thereby achieving the desired can opening function.

[0003] However, the initial locking action of the single-handle trimming can opener in the prior art is not user-friendly for first-time users and requires training before operation. When unlocking the double-handle trimming can opener, it is also inconvenient to separate the two handles with one hand. In addition, the number of teeth arranged on the driving cone rod of the can opener in the prior art is relatively large (40-48 teeth), such as Chinese patent: 202322577813.4. Therefore, when the driving cone rod rotates, the tooth marks produced by the front and rear teeth will not overlap, and a certain degree of misalignment and slippage will be formed between the two (such as the attached Figure 12 and attached Figure 13 ), which may cause the can lid to be scratched and iron filings to fall out. The iron filings may fall into the food, resulting in poor food safety. The greater the misalignment and slippage of the gear teeth, the more iron filings are generated. In view of the above problems, it is urgent to improve the can opener in the existing technology. Utility Model Content

[0040] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] See also Figures 1 to 13 A button trimming can opener includes a main body 100, a button 200, a driving unit 300 and a cutting unit 400. The button 200 is rotatably connected to the main body 100 through the driving unit 300, and the button 200 is provided with a pressing portion 210. The cutting unit 400 is installed on the main body 100 and forms a bite state with the driving unit 300. The driving unit 300 includes a gear rod 310, and the gear rod 310 has a driving shaft 311 and a gear plate 312. The gear plate 312 is connected to one end of the driving shaft 311, and a boss 313 is provided on the gear plate 312. The side wall of the boss 313 is spaced apart with 28-36 gear teeth 314. The bottom end of the gear teeth 314 extends toward the gear plate 312, and a smooth surface 315 is formed between the extended end and the edge of the gear plate 312.

[0044] Specifically, in this embodiment, the button 200 is rotatably connected to the main body 100, and a pressing portion 210 is provided on the button 200. When operating the button trimming can opener, the user pushes the pressing portion 210 upward or downward with the thumb, thereby rotating the button 200 relative to the main body 100, thereby driving the drive unit 300 to move axially, locking or unlocking the can 700 product, so as to achieve one-handed operation, making the button trimming can opener simple and convenient to operate. The upper handle of the double-handled trimming can opener in the prior art is creatively shortened and transformed into the button 200, and the pressing portion 210 is provided on the button 200, so as to form the button trimming can opener in the present invention, so that it has a simple structure and a reasonable design.

[0045] In addition, a boss 313 is provided on the gear plate 312, and 28-36 gear teeth 314 are distributed at intervals on the side walls of the boss 313, and the ends of the gear teeth 314 extend toward the gear plate 312, and the extended ends form a smooth surface 315 with the edge of the gear plate 312. By reducing the number of gear teeth 314 to 28-36, the tooth marks produced by the front and rear gear teeth 314 can overlap when the gear rod 310 rotates, thereby reducing misalignment and slippage, thereby effectively reducing the risk of scratching the edge 711 of the can cover 710 and causing iron filings to fall out. At the same time, because the extended ends of the gear teeth 314 are shorter, a smooth surface 315 is formed between them and the edge of the gear plate 312. Therefore, the smooth surface 315 can reduce the risk of scratching the edge 711 of the can cover 710, thereby reducing the generation of iron filings to ensure food safety.

[0046] The gear teeth 314 extending to the gear wheel plate 312 have a height of about 0.1 mm. By controlling the height of the gear teeth 314 within this range, the depth of the impression made by the gear teeth 314 when opening the can can be limited, thereby preventing the impression from being too deep and causing excessive iron filings to be generated. At the same time, the impression from being too shallow can prevent the impression from failing to achieve the required friction force, thereby allowing the gear teeth 314 to open the can normally and reducing the generation of iron filings, thereby ensuring food safety.

[0047] See also Figure 1 、 Figure 2 、 Figure 5 、 Figures 8 to 10 In order to facilitate the operation of the button trimming can opener, in this embodiment, an operation identification unit 500 is set on the main body 100, and the operation identification unit 500 includes an identification positioning support plate 510 and a support plate 520. There are two groups of identification positioning support plates 510, which are respectively located on both sides of the gear wheel 312, and the two groups of identification positioning support plates 510 are arranged opposite to each other, and the ends of the two groups of identification positioning support plates 510 are arc-shaped.

[0048] The U-shaped auxiliary positioning ring in the prior art is eliminated and designed into an operation identification unit 500, and the operation identification unit 500 includes two sets of identification positioning plates 510 and abutment plates 520. When opening the can 700 product, the two sets of identification positioning plates 510 are respectively pressed against the top of the can edge 711 of the can cover 710, and the abutment plates 520 are pressed against the side wall of the can 700 product. Then, the thumb acts on the pressing part 210 to move the driving unit 300 axially, so that the can 700 product can be locked to achieve the auxiliary positioning identification function. The button trimming can opener is easy and convenient to operate when in use. In addition, the two sets of identification and positioning plates 510 are respectively arranged on both sides of the gear wheel 312, and the ends of the two sets of identification and positioning plates 510 are arranged in an arc shape. Through the arc-shaped design of the ends, the user can better identify the purpose and position of the two sets of identification and positioning plates 510 when opening the can 700 product, so that the user can learn it at a glance when using it for the first time, thereby ensuring that the user is easy to learn and can better use the button trimming can opener in this embodiment.

[0049] Of course, since the identification and positioning plate 510 needs to be in contact with the can cover 710 when in use, and the identification and positioning plate 510 is made of plastic, in order to improve the strength of the identification and positioning plate 510, a reinforcement 511 is provided inside the identification and positioning plate 510, and the reinforcement 511 is made of stainless steel. The reinforcement 511 can improve the overall strength of the identification and positioning plate 510, thereby ensuring the auxiliary function of the button trimming can opener.

[0050] See also Figure 2 and Figure 3 The drive unit 300 in this embodiment also includes a sleeve 320, a first beveled wedge disk 330, a second beveled wedge disk 340 and a retaining spring 350. The first beveled wedge disk 330 is mounted on the main body 100, and the second beveled wedge disk 340 is mounted on the button 200, and the first beveled wedge disk 330 and the second beveled wedge disk 340 are arranged opposite to each other. The other end of the drive shaft 311 extends through the main body 100, the first beveled wedge disk 330, the second beveled wedge disk 340 and the button 200 in sequence, and a slot 316 is provided in the extension section. The retaining spring 350 is inserted into the slot 316 to limit the position between the button 200 and the main body 100. The sleeve 320 is sleeved on the drive shaft 311 and fixed to the main body 100. A return spring 360 is provided between the sleeve 320 and the gear plate 312.

[0051] By providing a sleeve 320 in the drive unit 300 and sleeved on the drive shaft 311, and the sleeve 320 is made of wear-resistant metal material, the drive shaft 311 can be effectively protected to avoid excessive wear of the drive shaft 311 during rotation, thereby increasing the service life of the gear rod 310, slowing down the position deviation of the drive shaft 311 due to wear and loss of the can opening function, and reducing costs. The sleeve 320 is made of a stamping process, which can reduce processing costs and improve processing efficiency.

[0052] When cutting the can lid 710 of the can 700 product, the user pushes the pressing portion 210 upward with the thumb to open the button 200 and the main body 100. When opening, the first inclined wedge plate 330 and the second inclined wedge plate 340 can make the gear rod 310 and the main body 100 move relative axially, so that the bite distance between the drive unit 300 and the cutting unit 400 is increased. At this time, the can edge 711 of the can lid 710 of the can 700 product is placed between the gear plate 312 and the cutter wheel 440 of the cutting unit 400 along the abutment plate 520. The user then presses the pressing portion 210 with the thumb to close the button 200 and the main body 100, and combines the first inclined wedge plate 330 and the second inclined wedge plate 340 to make the gear rod and the main body 100 move in the opposite axial direction, thereby lowering the can lid 710. The engagement distance between the low driving unit 300 and the cutting unit 400 is reduced, and the can edge 711 of the can cover 710 is tightened. At this time, the gear rod 310 is rotated again, so that the cutting unit 400 cuts around the can edge 711 of the can cover 710 until the cutting is completed. The cut can cover 710 can be directly extracted upward through the engagement of the driving unit 300 and the cutting unit 400. After extraction, the thumb pushes the pressing part 210 upward to open the button 200 and the main body 100, and combined with the first inclined wedge plate 330 and the second inclined wedge plate 340 and the reset compression spring 360, the gear rod 310 and the button 200 can be moved relative to each other again to increase the engagement distance between the gear plate 312 and the cutting unit 400, so that the cut can cover 710 can fall off.

[0053] In order to facilitate the driving and rotating of the gear rod 310, a knob 380 is connected to the extended section of the drive shaft 311. The knob 380 can facilitate the user to rotate the gear rod 310, thereby facilitating the cutting of the can lid. In order to reduce the wear between the knob 380 and the button 200, a washer 370 is also provided on the drive shaft 311. The washer 370 is located between the retaining spring 350 and the button 200. The washer 370 can effectively reduce the wear caused by the rotation of the knob 380, thereby increasing the overall service life of the button trimming can opener.

[0054] For further information, see Figure 6In order to ensure the axial movement of the drive unit 300 relative to the main body 100, the first beveled wedge plate 330 in this embodiment has a first beveled wedge surface 331, and a first beveled wedge protrusion 332 is provided on the first beveled wedge surface 331. The second beveled wedge plate 340 has a second beveled wedge surface 341, and the second beveled wedge surface 341 is arranged opposite to the first beveled wedge surface 331, and a second beveled wedge protrusion 342 corresponding to the first beveled wedge protrusion 332 is provided on the second beveled wedge surface 341.

[0055] The first and second beveled wedge plates 330, 340, which are made of powder metallurgy, are replaced by stamping processes, and the first beveled wedge plate 330 and the main body 100, and the second beveled wedge plate 340 and the button 200 are assembled in a split manner. This makes it easier to process the first and second beveled wedge plates 330, 40, and improves their processing accuracy. At the same time, it reduces the overall manufacturing cost of the button trimming can opener and increases its service life. When the pressing portion 210 is pushed to open the button 200 and the main body 100, the first beveled wedge protrusion of the first beveled wedge plate 330 is pressed against the main body 100. When the pressing portion 210 is pressed to close the button 200 and the main body 100, the first wedge protrusion 332 of the first wedge disk 330 and the second wedge protrusion 342 of the second wedge disk 340 abut against each other, causing the gear rod 310 to move axially again and squeeze the return compression spring 360 to realize the engagement of the driving unit 300 and the cutting unit 400, thereby realizing the cutting of the can edge 711 of the can cover 710 of the can 700 product.

[0056] See also Figure 2 、 Figure 3 and Figure 7 In order to cut canned products, the cutting unit 400 in this embodiment includes a cutter wheel shaft 410, a cutter wheel shaft sleeve 420, a supporting wheel 430 and a cutter wheel 440. A mounting groove 110 is opened on the main body 100, and the cutter wheel shaft 410 crosses the mounting groove 110. The cutter wheel shaft sleeve 420, the supporting wheel 430 and the cutter wheel 440 are respectively arranged in the mounting groove 110 and sleeved on the cutter wheel shaft 410. The cutter wheel 440 includes an integrally formed rotating part 441 and a cutting part 442. The cutting part 442 is located at one end of the rotating part 441 and protrudes outward.

[0057] The cutter wheel shaft sleeve 420, the supporting wheel 430 and the cutter wheel 440 are respectively arranged in the installation groove 110 of the main body 100 and fixed by the cutter wheel shaft 410, and the cutter wheel 440 cooperates with the gear plate 312 of the gear rod 310, so as to achieve the cutting of the can lid 710 of the can 700 product. At the same time, the original cutter wheel 440 is split into a separate cutter wheel 440 and a supporting wheel 430, and the cutter wheel 440 is first stamped and then lathe-processed, which can facilitate the processing of the cutter wheel 440, and the cutter wheel shaft sleeve 420 is made of engineering plastic with good wear resistance and high strength, and the cutter wheel shaft sleeve 420 is sleeved on the cutter wheel shaft 410, thereby effectively reducing the wear speed of the cutter wheel shaft 410, and then slowing down the deviation of the position of the cutter wheel shaft 410 due to wear and losing the can opening function, thereby improving the service life of the cutter wheel shaft 410 and reducing the processing cost.

[0058] Finally, see Figure 1 or Figure 2 In order to make the can opener easy to use, the button trimming can opener in this embodiment also includes a hand-held handle 600, and the hand-held handle 600 has a plug-in portion 610, and a plug-in slot 120 is provided on the main body 100. When the hand-held handle 600 and the main body 100 are installed, the plug-in portion 610 of the hand-held handle 600 is directly inserted into the plug-in slot 120 of the main body 100, so that the hand-held handle 600 and the main body 100 can be plugged and fixed. The hand-held handle 600 can be used to conveniently hold the button trimming can opener, and then the thumb can be used to push or press the pressing portion 210 of the button 200, thereby realizing one-handed operation, thereby making the button trimming can opener simple and convenient to operate.
