A press-type edge-cut can opener

Abstract

This invention discloses a press-type edge-cutting can opener, comprising a main body, a drive unit, and a cutting unit. The drive unit extends through the main body, and the main body has an installation groove. The cutting unit is located within the installation groove and cooperates with the drive unit. The cutting unit includes a blade wheel, a rubber sleeve, an elastic support plate, and a blade wheel shaft. The blade wheel, rubber sleeve, and elastic support plate are respectively located within the installation groove. The blade wheel shaft extends laterally through the installation groove, limiting the rubber sleeve and blade wheel. The outer end of the elastic support plate can deform and cooperates with the blade wheel and drive unit to bite the can. This press-type edge-cutting can opener replaces the axial movement of the drive unit in existing technologies with a can-feeding method using the deformation of the elastic support plate. This makes the can opener convenient and simple to use, especially beneficial for novice users. It also reduces the need for components such as wedge sleeves and springs in existing drive units, thereby reducing accumulated errors during assembly and improving the assembly accuracy and service life of the can opener.

Description

Technical Field

[0001] This invention relates to the field of household tools technology, and in particular to a press-type edge-cutting can opener. Background Technology

[0002] In daily life, there are many varieties of canned food, most of which are sealed in tin cans. When eating these canned foods, a blade is needed to cut open the lid in order to take out the food. Therefore, various can openers have appeared on the market. These edge-cutting can openers can be divided into two main categories: single-handle can openers and double-handle can openers.

[0003] Currently, existing can openers generally consist of a main body, a drive assembly, and a cutting assembly. The drive assembly includes a roller rod, a bushing, a wedge sleeve, and a through pin, etc. By driving the roller rod to rotate, the wedge sleeve and the through pin cooperate to act on the roller rod, thereby causing the roller rod to move axially. Figure 15 This is achieved by adjusting the distance between the drive group and the cutting group to engage and disengage the can lid, as described in the applicant's Chinese patent application: 2023225781300. However, when using a can opener to engage the can lid, the distance between the drive group and the cutting group needs to be adjusted by rotating the toothed rod. When novice users adjust the distance to a small margin before using the can opener, they may experience difficulty in inserting the can, making the existing can opener unfriendly to novice users. Furthermore, because the drive group of existing can openers has many components, it leads to a large accumulation of errors after assembly, resulting in low assembly accuracy and instability in the quality of the can opener. The large number of components also inevitably leads to low production efficiency, high production costs, and a short service life. Summary of the Invention

[0004] The purpose of this invention is to provide a press-type edge-cutting can opener that is easy to use, has high assembly accuracy, low cost, and long service life.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions: A press-type edge-cutting can opener includes a main body, a drive unit, and a cutting unit. The drive unit extends through the main body and has an installation groove on it. The cutting unit is located within the installation groove and cooperates with the drive unit. The cutting unit includes a blade wheel, a rubber sleeve, an elastic support plate, and a blade wheel shaft. The blade wheel, rubber sleeve, and elastic support plate are respectively located within the installation groove, while the blade wheel shaft passes through the installation groove to confine the blade wheel and rubber sleeve within it. The elastic support plate deforms under external force and slides from the side of the can edge to the lower part of the can edge, thereby supporting the bottom of the can edge. At this time, the elastic support plate, the blade wheel, and the drive unit form a three-point force to engage the can edge. The existing design changes the axial movement of the drive unit to a fixed position. An inclined guide surface is added to the toothed wheel disc of the toothed wheel rod in the drive unit. An elastic support is added to the existing cutting unit, and the deformation of the elastic support engages with the inclined guide surface of the toothed wheel disc. This makes the can opener of this invention easy and simple to operate when inserting the can (engaging with the can edge), facilitating operation for novice users. Furthermore, since the drive unit does not require axial movement, components such as the wedge sleeve, through pin, butterfly spring, and spring in the existing drive unit can be eliminated. This reduces the number of assembly parts in the can opener, lowers accumulated errors during assembly, improves assembly accuracy, ensures quality stability, increases production efficiency, reduces production costs, and extends service life.

[0006] In one embodiment, the mounting groove is provided with a slot, the elastic support is inserted into the slot, and the outer side of the slot is provided with an inclined surface, through which a movable space can be formed so that the outer end of the elastic support can deform within the movable space.

[0007] In one embodiment, the drive unit includes a gear rod, a bushing, a washer, and a retaining ring. A gear disc is provided at one end of the gear rod, and the gear disc has an inclined guide surface. The other end of the gear rod extends through the main body and has a groove at the extended end. The retaining ring is inserted into the groove to limit the position of the gear rod. The bushing is sleeved on the gear rod and located at the end where the gear disc is located. The washer is located between the retaining ring and the main body.

[0008] In one embodiment, the axial direction of the roller rod is perpendicular to the axial direction of the cutter wheel shaft, and the roller disc of the roller rod is positioned towards the cutting edge of the cutter wheel.

[0009] In one embodiment, the drive unit includes a gear rod, bushings, washers, and retaining rings. A gear disc is provided at one end of the gear rod, and the gear disc has an inclined guide surface. The other end of the gear rod extends through the main body and has a groove at the extended end. The retaining ring is inserted into the groove to limit the movement of the gear rod. Two bushings are sleeved on the gear rod, one bushing being located close to the gear disc and the other bushing being located close to the retaining ring. The washer is located between the bushing and the retaining ring.

[0010] In one embodiment, the axial direction of the roller rod is set at an angle of 12°-16° with the axial direction of the cutter wheel shaft, and the roller rod's roller disc is set towards the cutting edge of the cutter wheel.

[0011] In one embodiment, a knob is connected to the end of the extension of the gear rod, and the knob and the gear rod are connected by an interference fit.

[0012] In one embodiment, both the rubber sleeve and the bushing are made of engineering plastic material.

[0013] In one embodiment, the body has a hand handle and is provided with a backrest, a boss and a functional hook.

[0014] In one embodiment, the cutting wheel is manufactured by first stamping and then finishing on a lathe. Beneficial effects

[0015] 1. In the present invention, the press-type edge-cutting can opener is used by placing the edge of the can lid within the gap between the drive unit and the cutting unit, and then pressing the entire can opener to deform the elastic support in the cutting unit. When the elastic support deforms, it works with the cutter wheel and the drive unit to bite the can. The can opening method of elastic support deformation replaces the can opening method of axial movement of the drive unit in the prior art, so that the can opener is convenient and simple to use and is beneficial to novice users.

[0016] 2. The press-type edge-cutting can opener of this invention uses an elastic tray deformation can-feeding method instead of the axial movement of the drive unit in the prior art. This reduces the number of components such as wedge sleeves, pins, springs, and butterfly springs in the drive unit of the prior art, thereby reducing the overall assembly parts of the can opener. This reduces the accumulated error during the assembly of the can opener and improves the assembly accuracy of the can opener. At the same time, it can also ensure the quality stability of the can opener. In addition, by reducing the number of assembly parts, it can also effectively improve the production efficiency of the can opener, reduce the production cost of the can opener, and increase the service life of the can opener.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1 to 9 A press-type edge-cutting can opener includes a main body 100, a drive unit 200, and a cutting unit 300. The drive unit 200 extends through the main body 100 and has a mounting groove 110 on the main body 100. The cutting unit 300 is disposed in the mounting groove 110 and cooperates with the drive unit 200. The cutting unit 300 includes a cutter wheel 310, a rubber sleeve 320, an elastic support plate 330, and a cutter wheel shaft 340. The elastic support plates 330 are respectively set in the mounting groove 100, and the cutter wheel shaft 340 passes through the mounting groove 110 and limits the rubber sleeve 320 and the cutter wheel 310. The elastic support plates 330 deform under the action of external force and slide from the side of the can edge 420 to the bottom of the can edge 420, thereby supporting the bottom of the can edge 420. At this time, the elastic support plates 330, the cutter wheel 310 and the drive unit 200 form a three-point force to engage the can edge 420.

[0023] Specifically, in this embodiment, when using the can opener, the edge 420 of the can lid 410 is placed within the gap between the drive unit 200 and the cutting unit 300. Then, the entire can opener is pressed down, causing the outer end of the elastic support piece 330 in the cutting unit 300 to deform and spring outward. After springing out, the outer end of the elastic support piece 330 will lock onto the lower part of the can edge 420, and cooperate with the cutter wheel 310 and the drive unit 200 to bite the can (grip the edge 420 of the can lid 410). At this time, the drive unit 200 is then driven forward. The can opener rotates, thereby driving the cutting unit 300 to cut the can edge 420. After one round of cutting, the can lid 410 can be directly removed by the elastic support 330 and the drive unit 200. When the drive unit 200 is rotated in the opposite direction, the cutting unit 300 can be removed from the can edge 420, and the can lid 410 will fall off automatically. Finally, the can opening method by the deformation of the elastic support 330 replaces the can opening method of the drive unit 200 moving axially in the prior art, so that the can opener is convenient and simple to use, and is beneficial to novice users.

[0024] Meanwhile, by using an elastic support plate 330 to deform and feed the can instead of the axial movement of the drive unit 200 in the prior art, the drive unit 200 no longer needs to move axially to feed the can, thus forming a fixed structure. This reduces the number of components such as the wedge sleeve, spring, pin, and butterfly spring in the drive unit 200 in the prior art, thereby reducing the number of assembly parts of the can opener. This reduces the accumulated error during the assembly of the can opener and improves the assembly accuracy of the can opener. At the same time, it can also ensure the quality stability of the can opener. In addition, by reducing the number of assembly parts, it can also effectively improve the production efficiency of the can opener, reduce the production cost of the can opener, and increase the service life of the can opener.

[0025] Furthermore, in order to facilitate the processing of the cutting unit 300, the cutter wheel 310 in this embodiment is made by first stamping and then precision machining on a lathe, which facilitates the processing of the cutter wheel 310, thereby improving the processing efficiency of the cutter wheel 310 and reducing production costs; at the same time, the rubber sleeve 320 is made of engineering plastic material, which can effectively reduce production costs.

[0026] Additionally, please see Figure 5To facilitate the use of the can opener by novice users, the main body 100 also has a handle 120. The handle 120 can be integrated with the main body 100 or it can be separate from the main body 100. The handle 120 allows users to easily hold the can opener, thus improving the user experience. At the same time, the retaining ring 130 and the boss 140 on the main body 100 can help to abut and position the can opener against the can body 400 and the can lid 140. The main body 100 is also equipped with a functional hook 130, which can be used to hook and pull the lid of products such as aluminum cans, thereby making it easier to open the lid and improving the versatility of the can opener.

[0027] Please see Figure 2 , Figure 3 and Figure 5 In order to install the elastic support 330 and enable the outer end of the elastic support 330 to deform, in this embodiment, a slot 111 is provided in the mounting groove 110, the elastic support 330 is inserted into the slot 111, and an inclined surface 112 is provided on the outer side of the slot 111. The inclined surface 112 can form a movable space so that the outer end of the elastic support 300 can deform in the movable space.

[0028] By providing a slot 111 within the mounting groove 110, the inner end of the elastic support 330 can be directly inserted. This insertion can be achieved using an interference fit, allowing the elastic support 330 to be placed within the mounting groove 110. The inclined surface 112 on the outer side of the slot 111 creates a movable space, facilitating the expansion or repositioning of the outer end of the elastic support 330. This allows the elastic support 330 to deform, enabling it to enter the can (engage with the edge 420 of the can lid 410). This results in a reasonable overall structural design for the can opener. Furthermore, the elastic support 330 can be designed in a 'U' shape to reduce its deformation area, making the expansion or repositioning of its outer end smoother. This also allows the can opener to deform without requiring significant force when pressed, ultimately making it easier for initial users to operate the can opener.

[0029] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7In one embodiment, in order for the drive unit 200 to drive the cutting wheel 310 in the cutting unit 300 to perform circumferential cutting on the can lid during operation, the drive unit in this embodiment includes a roller rod 210, a bushing 220, a washer 230, and a retaining ring 240. A roller disc 211 is provided at one end of the roller rod 210, and an inclined guide surface 211a is provided on the roller disc 211. The other end of the roller rod 210 extends laterally through the main body 10. The toothed rod 210 is extended, and the toothed disc 211 of the toothed rod 210 is set towards the extended end so that the toothed disc 211 and the cutting edge of the cutter wheel 310 cooperate with each other. A groove 212 is provided at the extended end of the toothed rod 210, and a retaining spring 240 is inserted into the groove 212 to limit the toothed rod 210. A bushing 220 is sleeved on the toothed rod 210 and is located at the end where the toothed disc 211 is located. A washer 230 is located between the retaining spring 240 and the main body 100.

[0030] By extending the roller rod 210 laterally through the main body 100, the axial direction of the roller rod 210 is perpendicular to the axial direction of the cutter wheel shaft 340. This perpendicular arrangement allows the can opener to feed cans using a side-pressure method. When feeding cans using the side-pressure method, the roller disc 211 of the roller rod 210 needs to be positioned towards its extended end so that the roller disc 211 can cooperate with the cutting edge of the cutter wheel 310 and the elastic support plate 330, thereby making the structural design of the can opener reasonable. Specifically, when cutting the can lid 410, the roller rod 210 can be driven to rotate. When the roller rod 210 rotates, the roller disc 211 at its end will rotate along the top of the can edge 420 of the can lid 410, thereby driving the cutter wheel 310 in the cutting unit 300 to perform a circumferential cut on the side wall of the can edge 420 of the can lid 410, thus achieving the cutting and opening of the can lid 410. The bushing 220 can effectively improve the stress strength of the roller disc 211, thereby improving the overall service life of the roller rod 210. At the same time, replacing the original steel bushing 220 with a bushing 220 made of engineering plastic material can also effectively reduce production costs. The washer 230 can effectively reduce the wear caused by the retaining spring 240 on the main body 100, thereby improving the service life of the can opener.

[0031] Meanwhile, to facilitate can loading and opening, the toothed disc 211 in this embodiment has an inclined guide surface 211a. When opening the can, the user can apply lateral pressure to the entire can opener, causing the elastic support 330 to deform. When deformed, the elastic support 300 will cooperate with the inclined guide surface 211a to facilitate the elastic support 330 and the toothed disc 211 to enter the can lid 410 along the can edge 420. Then, by driving the toothed rod 210 to rotate, the toothed disc 211 rotates and carries the cutting wheel 310 in the cutting unit 300 to perform a circumferential cut on the can lid 410 along the can edge 420, thereby cutting and opening the canned product. Finally, through the cooperation of the inclined guide surface 211a of the toothed disc 211 and the deformation of the elastic support 330, the operation of the can opener is convenient and simple for the user, making the operation of the can opener user-friendly for beginners.

[0032] The specific can-opening process in this embodiment is as follows: The can opener is placed on the canned product, and the guide surface 211a of the toothed disc 211 allows the edge 420 of the can lid 410 to easily be positioned between the drive unit 200 and the cutting unit 300. At the same time, the retaining ring 130 abuts against the top of the can lid 410. Then, the handle 120 is pressed. When pressed, the elastic support plate 330 deforms and springs outward under the action of external force. The cutting wheel 310 and the support wheel 320 will cut into the side wall of the can edge 420. When pressed to a certain extent, the elastic support plate... 330 will be stuck at the bottom of the can edge 420, the toothed disc 211 will press against the top of the can edge 420, and the boss 140 will abut against the side wall of the can body 400, thereby causing the toothed disc 211 and the elastic support plate 300 to bite the edge of the can lid 410. Then, the knob 250 is rotated to make the toothed rod 210 rotate. When the toothed rod 210 rotates, the toothed disc 211 will rotate along the top of the can edge 420 and drive the cutter wheel 310 to make a circumferential cut along the side wall of the can edge 420, thereby cutting and opening the can lid 410.

[0033] Please see Figures 10 to 14In another embodiment, the provided drive unit 200 is basically the same as the drive unit 200 in other embodiments, the main difference being that: the drive unit 200 in this embodiment includes a gear rod 210, a bushing 220, a washer 230, and a retaining ring 240. A gear disc 211 is provided at one end of the gear rod 210, and an inclined guide surface 211a is provided on the gear disc 211. The other end of the gear rod 210 extends vertically through the main body 100, and the gear disc 211 of the gear rod 210 is positioned in the opposite direction to the extending end. The cutting edges of the gear disc 211 and the cutter wheel 310 are engaged with each other. The axial direction of the gear rod 210 is in the same direction as the axial direction of the cutter wheel shaft 340. A groove 211 is provided at the extended end of the gear rod 210. A retaining spring 240 is inserted into the groove 211 to limit the gear rod 210. Two bushings 220 are sleeved on the gear rod 210. One bushing 220 is located close to the gear disc 211, and the other bushing 220 is located close to the retaining spring 240. A washer 230 is disposed between the bushing 220 and the retaining spring 240.

[0034] By vertically penetrating the main body 100, the axial direction of the roller rod 210 is set at an angle of 12°-16° with the axial direction of the cutter wheel shaft 340. This angle setting allows the can opener to feed the can in a direct pressure (downward pressing) manner during use. When feeding the can in a direct pressure manner, the roller disc 211 of the roller rod 210 needs to be set in the opposite direction of its extension end so that the roller disc 211 can cooperate with the cutting edge of the cutter wheel 310 and the elastic support plate 330. This makes the structural design of the can opener reasonable and also makes it convenient for users (left-handed users) to use the can opener. Similarly, when cutting the can lid 410, the roller rod 210 can be driven to rotate. When the roller rod 210 rotates, the roller disc 211 at its end will rotate along the top of the can edge 420 of the can lid 410, thereby driving the cutter wheel 310 in the cutting unit 300 to perform a circumferential cut on the can edge 420 of the can lid 410, thus achieving the cutting and opening of the can lid 410. Furthermore, the bearing strength of the roller disc 211 can be effectively improved by one of the bushings 220, thereby improving the overall service life of the roller rod 210. At the same time, replacing the original steel bushing 220 with a bushing 220 made of engineering plastic material can also effectively reduce production costs. The washer 230 can effectively reduce the wear between the retaining spring 240 and the other bushing 220, thereby improving the service life of the can opener.

[0035] Finally, please see Figure 2 and Figure 11To facilitate the use of the can opener, a knob 250 is connected to the extension end of the toothed rod 210. The extension end of the toothed rod 210 is designed to be flat and is interference-fitted with the knob 250 to facilitate the assembly and connection of the toothed rod 210 and the knob 250. Of course, the knob 250 and the toothed rod 210 can also be connected by thread or other means. The knob 250 allows the user to easily rotate the toothed rod 210, thereby driving the toothed disc 211 at the end of the toothed rod 210 to rotate, so as to drive the cutting wheel 310 in the cutting unit 300 to perform a circumferential cut on the can lid 410, thus facilitating the cutting of the can lid 410.

[0036] In summary, the difference between this invention and the prior art is as follows: In the prior art, when opening a can, the user needs to first rotate the roller rod. When the roller rod rotates, the pin acts on the wedge sleeve, causing the roller rod to move axially (1mm). Through the axial movement of the roller rod, the roller disc cooperates with the cutting unit to bite the can lid of the canned product (biting the can). After biting, the user drives the roller rod to rotate again, causing the roller disc with the cutter wheel to perform a circumferential cut on the can lid, thus cutting and opening the can lid. After opening the can lid, the user rotates the roller rod in the opposite direction, and through the cooperation of the pin, the wedge sleeve, and the return spring, the roller rod moves axially in the opposite direction to return to its original position, increasing the distance between the roller disc and the cutting unit. At this point, the cut can lid can be directly discarded. Therefore, the can opener in the prior art is a biting method where the drive unit moves axially and the cutting unit is fixed.

[0037] In this embodiment, when opening the can, the edge 420 of the can lid 410 is placed between the drive unit 200 and the cutting unit 300. Then, the can opener is pressed laterally or directly, causing the outer end of the elastic support 330 in the cutting unit 300 to spring open and deform. When the elastic support 330 deforms, it will cooperate with the inclined guide surface 211a of the toothed wheel 211 of the toothed wheel 210 in the drive unit 200 to bite the can (bite the edge 420 of the can lid 410). At this time, the drive unit 200 is driven to rotate, thereby driving the cutting unit 300 to cut the edge 420 of the can lid 410. After cutting, the can lid 410 can be directly removed and discarded through the elastic support 330 and the toothed wheel 211 in the drive unit 200. Therefore, the can opener in this invention is a biting method in which the elastic support 330 deforms and the drive unit 200 is fixed.

[0038] Ultimately, the axial movement of the drive unit 200 in the existing design is changed to a fixed drive unit 200. An inclined guide surface 211a is provided on the toothed disc 211 of the toothed rod 210 in the drive unit 200. At the same time, an elastic support plate 330 is added to the cutting unit 300. The deformation of the elastic support plate 300 cooperates with the inclined guide surface 211a of the toothed disc 211, so that the can opener of the present invention is convenient and simple when biting the can (biting the edge 420 of the can lid 410), so that novice users can operate the can opener. Since the drive unit 200 does not need to move axially, the wedge sleeve, pin, butterfly spring and spring and other components in the drive unit of the prior art can be eliminated, thereby reducing the number of assembly parts of the can opener, reducing the accumulated error during the assembly of the can opener, improving the assembly accuracy, ensuring quality stability and improving production efficiency, and further reducing production costs and increasing service life.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art can readily implement this invention based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the invention's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this invention; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this invention still fall within the protection scope of this invention's technical solution.
