[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. Utility Model Content

[0038] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the present application. The specific embodiments of the present application are described below.

[0039] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. In addition, when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. Like numbers refer to like elements throughout.

[0040] 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 application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "may" and "can" include any one of, or all of, the possible combinations of the aspects described.

[0041] Reference will now be made to Figures 1 to 9The utility model provides a press type side cutting can opener, including main body 100, drive unit 200 and cutting unit 300, drive unit 200 is arranged through main body 100 and is set with installation groove 110 on main body 100, cutting unit 300 is located in installation groove 110 and is mutually cooperative with drive unit 200, cutting unit 300 includes cutter wheel 310, rubber sleeve 320, elastic supporting piece 330 and cutter wheel shaft 340, cutter wheel 310, rubber sleeve 320 and elastic supporting piece 330 are arranged in installation groove 100 respectively, and cutter wheel shaft 340 is arranged through installation groove 110 and limits rubber sleeve 320 and cutter wheel 310, elastic supporting piece 330 is deformed under the action of external force, and then slips into the lower part of can edge 420 from the side of can edge 420 to support the bottom of can edge 420, and three point forces between elastic supporting piece 330, cutter wheel 310 and drive unit 200 are formed to bite can edge 420.

[0042] Specifically, when the can opener is used, the can edge 420 of the can cover 410 is placed in the interval between the drive unit 200 and the cutting unit 300, and the can opener is pressed as a whole, so that the outer end of the elastic supporting piece 330 in the cutting unit 300 is deformed and then pops outwards. After the elastic supporting piece 330 pops out, the outer end of the elastic supporting piece 330 is clamped to the lower part of the can edge 420 and cooperates with the cutter wheel 310 and the drive unit 200 to bite the can edge 420 (to tightly bite the can edge 420 of the can cover 410). At this time, the drive unit 200 is driven to rotate, thereby driving the cutting unit 300 to cut the can edge 420. After cutting for one turn, the can cover 410 can be directly removed by the elastic supporting piece 330 and the drive unit 200. When the drive unit 200 is reversely driven to rotate, the cutting unit 300 exits the can edge 420. At this time, the can cover 410 will automatically fall out. Finally, the deformation of the elastic supporting piece 330 replaces the axial movement of the drive unit 200 in the prior art, so that the can opener is convenient and simple to use, and is beneficial for novice users to use for the first time.

[0043] Meanwhile, since the deformation of the elastic supporting piece 330 replaces the axial movement of the drive unit 200 in the prior art, the drive unit 200 does not need to move axially to enter the can, and a fixed structure can be formed, thereby reducing the components such as the wedge sleeve, spring, pin, and butterfly-shaped elastic piece of the drive unit 200 in the prior art. In this way, the overall assembly components of the can opener are reduced, the accumulated error during assembly of the can opener is reduced, the assembly precision of the can opener is improved, the quality stability of the can opener is ensured, and the production efficiency of the can opener is effectively improved, the production cost of the can opener is reduced, and the service life of the can opener is improved.

[0044] And in order to facilitate the processing of cutting unit 300, the cutter wheel 310 of the embodiment is made by first stamping and then lathe finishing, so that the cutter wheel 310 can be easily processed to improve the processing efficiency of the cutter wheel 310 and reduce the production cost; meanwhile, the rubber sleeve 320 is made of engineering plastic material, which can effectively reduce the production cost.

[0045] In addition, please refer to Figure 5 , in order to facilitate the use of the opener for novice users, therefore, the main body 100 also has a hand handle 120, the hand handle 120 and the main body 100 can be integrally arranged, also can adopt the split setting, through the hand handle 120 can facilitate the user to hold the opener, so as to better use the opener, in order to improve the user's experience; at the same time, through the main body 100 on the ring 130 and the boss 140 can be convenient for the opener and the can body 400 and the can cover 140 to assist the abutting positioning, and the main body 100 is also provided with a function hook 130, through the function hook 130 can hook the can cover of the pop can and other products, and then facilitate the opening, thereby improving the multifunctionality of the opener.

[0046] Please refer to Figure 2 、 Figure 3 and Figure 5 , in order to install the elastic supporting piece 330 and make the outer end of the elastic supporting piece 330 deformable, therefore, in the embodiment, the installation slot 110 is provided with a insertion slot 111, the elastic supporting piece 330 is inserted in the insertion slot 111, and the outer side of the insertion slot 111 is provided with an inclined surface 112, which can form a movement space to make the outer end of the elastic supporting piece 300 deform in the movement space.

[0047] By setting the insertion slot 111 in the installation slot 110, the inner end of the elastic supporting piece 330 can be directly inserted, which can be interference fit, so that the elastic supporting piece 330 is placed in the installation slot 110, and the inclined surface 112 on the outer side of the insertion slot 111 can form a movement space, so that the outer end of the elastic supporting piece 330 can be expanded or reset to facilitate the deformation of the elastic supporting piece 330. By deforming the outer end of the elastic supporting piece 330, the opener can be realized into the can (engaging the can edge 420 of the can cover 410), so that the overall structure of the opener is reasonable; in addition, the elastic supporting piece 330 can also be designed as 'U' type, so as to reduce the deformation area of the elastic supporting piece 330, make the outer end of the elastic supporting piece 330 more smoothly expanded or reset, and make the opener not need to exert a large force when pressing, so as to facilitate the use of the opener for the initial user.

[0048] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 7In one of the embodiments, in order to drive the cutter 310 in the cutting unit 300 to cut the can lid when the driving unit 200 is in operation, the driving unit in the embodiment comprises the cutter rod 210, the shaft sleeve 220, the washer 230 and the circlip 240. The cutter disc 211 is arranged at one end of the cutter rod 210, and the inclined guide surface 211a is arranged on the cutter disc 211. The other end of the cutter rod 210 extends transversely through the main body 100, and the cutter disc 211 of the cutter rod 210 is arranged towards the extending end, so that the cutter disc 211 cooperates with the cutting edge of the cutter 310. The clamping groove 212 is arranged at the extending end of the cutter rod 210, and the circlip 240 is clamped into the clamping groove 212 to limit the cutter rod 210. The shaft sleeve 220 is sleeved on the cutter rod 210 and located at the end with the cutter disc 211. The washer 230 is located between the circlip 240 and the main body 100.

[0049] By transversely penetrating the cutter rod 210 through the main body 100, the axial direction of the cutter rod 210 is arranged vertically to the axial direction of the cutter shaft 340. By vertical arrangement, the can opener is arranged in a side-pressing mode when in use. When the side-pressing mode is adopted, the cutter disc 211 of the cutter rod 210 needs to be arranged towards the extending end, so that the cutter disc 211 cooperates with the cutting edge of the cutter 310 and the elastic supporting piece 330, thereby making the structure design of the can opener reasonable. When cutting the can lid 410, the cutter rod 210 is driven to rotate, and the cutter disc 211 at the end of the cutter rod 210 rotates along the top of the can edge 420 of the can lid 410, thereby driving the cutter 310 in the cutting unit 300 to cut the can edge 420 of the can lid 410, so as to cut and open the can lid 410. The shaft sleeve 220 can effectively improve the stress intensity of the cutter disc 211, thereby improving the overall service life of the cutter rod 210. The original shaft sleeve 220 made of steel is replaced by the shaft sleeve 220 made of engineering plastic, which can also effectively reduce the production cost. The washer 230 can effectively reduce the wear of the main body 100 caused by the circlip 240, thereby improving the service life of the can opener.

[0050] Meanwhile, in order to facilitate the can entering and the can opening, the toothed disc 211 has an inclined guide surface 211a in the embodiment, when the can is opened, the user can press the can opener laterally, so that the elastic supporting sheet 330 is deformed, and the elastic supporting sheet 300 is matched with the inclined guide surface 211a when it is deformed, so as to facilitate the elastic supporting sheet 330 and the toothed disc 211 to enter the can edge 420 of the can cover 410, and then the toothed disc 211 is rotated by driving the toothed rod 210, so that the toothed disc 211 is rotated and the cutter wheel 310 in the cutting unit 300 is used to cut the can edge 420 of the can cover 410, so as to cut and open the can cover, and finally the user can operate the can opener conveniently and simply, and the operation of the can opener is friendly to the initial user.

[0051] The specific can opening process of the embodiment is as follows: the can opener is placed on the can product, the can edge 420 of the can cover 410 is easily positioned between the driving unit 200 and the cutting unit 300 by the guide surface 211a of the toothed disc 211, and the ring 130 is abutted on the top of the can cover 410, then the handle 120 is pressed, when the handle 120 is pressed, the elastic supporting sheet 330 is deformed and pops out under the action of the external force, the cutter wheel 310 and the supporting wheel 320 are cut into the sidewall of the can edge 420, when the handle 120 is pressed to a certain degree, the elastic supporting sheet 330 is clamped on the bottom of the can edge 420, the toothed disc 211 is abutted on the top of the can edge 420, the boss 140 is abutted on the sidewall of the can body 400, so that the toothed disc 211 and the elastic supporting sheet 300 clamp the can edge of the can cover 410, then the knob 250 is rotated, so that the toothed rod 210 is rotated, when the toothed rod 210 is rotated, the toothed disc 211 is rotated along the top of the can edge 420, and the cutter wheel 310 is used to cut the sidewall of the can edge 420, so as to cut and open the can cover 410.

[0052] Please refer to Figures 10 to 14In another embodiment, the provided driving unit 200 is basically the same as the driving unit 200 in other embodiments, the main difference is that the driving unit 200 in this embodiment includes a roller lever 210, a shaft sleeve 220, a washer 230 and a circlip 240, the roller lever 210 is provided with a roller disc 211 at one end, and the roller disc 211 is provided with an inclined guide surface 211a, the other end of the roller lever 210 extends in the vertical direction through the main body 100, and the roller disc 211 of the roller lever 210 is arranged towards the opposite direction of the extension end, so that the roller disc 211 cooperates with the cutting edge of the cutter wheel 310, the axial direction of the roller lever 210 is arranged in the same direction as the axial direction of the cutter shaft 340, and the extension end of the roller lever 210 is provided with a clamping groove 211, the circlip 240 is clamped into the clamping groove 211 to limit the roller lever 210, and two shaft sleeves 220 are sleeved on the roller lever 210, one of the shaft sleeves 220 is arranged close to the roller disc 211, and the other shaft sleeve 220 is arranged close to the circlip 240, and the washer 230 is arranged between the shaft sleeve 220 and the circlip 240.

[0053] By penetrating the roller lever 210 in the vertical direction through the main body 100, the axial direction of the roller lever 210 is arranged at an angle of 12°-16° with the axial direction of the cutter shaft 340, and the angle is arranged to form a can opener in a straight pressing (downward pressing) mode when in use. When the can opener is used in a straight pressing mode, the roller disc 211 of the roller lever 210 needs to be arranged towards the opposite direction of the extension end, so that the roller disc 211 cooperates with the cutting edge of the cutter wheel 310 and the elastic supporting piece 330, thereby making the structure design of the can opener reasonable, and also facilitating the user (left-handed user) to use the can opener. Similarly, when cutting the can cover 410, the roller lever 210 can be driven to rotate, and when the roller lever 210 rotates, the roller disc 211 at the end thereof rotates along the top of the can edge 420 of the can cover 410, thereby driving the cutter wheel 310 in the cutting unit 300 to cut the can edge 420 of the can cover 410, so as to realize the cutting and opening of the can cover 410. The shaft sleeve 220 can effectively improve the stress intensity of the roller disc 211, thereby improving the overall service life of the roller lever 210, and replacing the original steel shaft sleeve 220 with an engineering plastic shaft sleeve 220 can also effectively reduce the production cost. The washer 230 can effectively reduce the wear between the circlip 240 and the other shaft sleeve 220, thereby improving the service life of the can opener.

[0054] Finally, please refer to Figure 2 and Figure 11, in order to facilitate the use of the can opener, the extension section of the gear rod 210 is connected with a knob 250, the extension section of the gear rod 210 is designed to be flat, and the knob 250 is inserted into the extension section of the gear rod 210 in an interference fit, so as to facilitate the assembly and connection of the gear rod 210 and the knob 250. Of course, the knob 250 and the gear rod 210 can also be connected by thread connection and the like, and the knob 250 can facilitate the user to rotate the gear rod 210, thereby driving the gear disc 211 at the end of the gear rod 210 to rotate, so as to drive the cutter 310 in the cutting unit 300 to cut the can cover 410, thereby facilitating the cutting of the can cover 410.

[0055] In summary, the difference between the utility model and the prior art is that: in the prior art, the user needs to first drive the gear rod to rotate, and the pin will act on the wedge sleeve when the gear rod rotates, so as to move the gear rod axially (1mm). Through the axial movement of the gear rod, the gear disc and the cutting unit cooperate to clamp the can cover of the can product (clamp the can), after clamping, the user drives the gear rod to rotate, and the gear disc drives the cutter to cut the can cover, thereby cutting and opening the can cover. After opening, the user reverses the gear rod, and through the cooperation of the pin, the wedge sleeve and the return spring, the gear rod moves axially in the reverse direction to reset, so that the distance between the gear disc and the cutting unit increases. At this time, the cut can cover can be directly discarded. Therefore, the can opener in the prior art is a clamping can method with fixed cutting unit and axial movement of the driving unit.

[0056] In the embodiment, when opening the can, the can edge 420 of the can cover 410 of the can product is placed between the driving unit 200 and the cutting unit 300, and then the can opener is pressed laterally or directly, so that the outer end of the elastic supporting piece 330 in the cutting unit 300 is opened and deformed. When the elastic supporting piece 330 deforms, it cooperates with the inclined guide surface 211a of the gear disc 211 of the gear rod 210 in the driving unit 200 to clamp the can (clamp the can edge 420 of the can cover 410). At this time, the driving unit 200 is driven to rotate, thereby driving the cutting unit 300 to cut the can edge 420 of the can cover 410. After cutting, the can cover 410 can be directly removed and discarded by the elastic supporting piece 330 and the gear disc 211 in the driving unit 200. Therefore, the can opener in the utility model is a clamping can method with fixed driving unit 200 and deformed elastic supporting piece 330.

[0057] Finally, the axial movement of the driving unit 200 in the existing design is changed to the fixed driving unit 200, and the inclined guide surface 211a of the gear disc 211 of the gear rod 210 in the driving unit 200 is arranged, and the elastic supporting piece 330 is added in the cutting unit 300, the deformation of the elastic supporting piece 300 cooperates with the inclined guide surface 211a of the gear disc 211, so that the can opener in the utility model is convenient and simple when biting the can (engaging the can edge 420 of the can cover 410), so as to facilitate the operation of the can opener by the novice user; and since the driving unit 200 does not need to move axially, the inclined wedge sleeve, the through pin, the butterfly-shaped elastic sheet and the spring and other components in the driving unit in the prior art can be reduced, thereby reducing the assembly components of the can opener, reducing the accumulated error during assembly of the can opener, improving the assembly precision, ensuring the quality stability and improving the production efficiency, and further reducing the production cost, prolonging the service life.

[0058] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Any person skilled in the art can smoothly implement the utility model according to the drawings shown in the specification and the above description; however, any slight change, modification and equivalent change of the above-mentioned technical content within the scope of the technical scheme of the utility model, made by any person skilled in the art without departing from the scope of the utility model, is an equivalent embodiment of the utility model; at the same time, any equivalent change, modification and evolution of the above-mentioned embodiments according to the essential technology of the utility model still belongs to the protection scope of the technical scheme of the utility model.
