Description

Technical Field

[0001] This utility model relates to the field of household tools technology, and in particular to an electric can opener. Background Technology

[0002] For convenience, people often process cooked foods and seal them in cans. When needed, they simply open the can lid to eat, which is very quick. A can opener can be placed on top of the can and rotates relative to it during operation. By driving the rotating shaft to rotate, the shaft engages with a cutter, thereby cutting the can lid of the canned product.

[0003] However, most existing can openers are manual can openers. These manual can openers specifically include a handle, a drive assembly, and a cutting assembly. The drive assembly and the cutting assembly are respectively mounted on the handle and work together to open the can, as shown in Chinese Patent CN221070938U. Although the above-mentioned manual can openers can improve the accuracy of assembly, reduce processing costs, and increase service life, they cannot achieve automatic cutting and opening of cans and still require manual operation by the user, which leads to poor practicality of manual can openers.

[0004] Of course, there are also a small number of electric can openers on the market, but these electric can openers use a motor and multiple gears to drive the shaft of the drive unit to rotate. Their power transmission efficiency is low, and they generate a lot of noise when the transmission is sequential. As a result, the practicality of these electric can openers is also poor, which affects the user experience. Therefore, there is an urgent need to design a better electric can opener to solve the above problems. Utility Model Content

The housing also contains a main body, on which the transmission unit and the cutting unit are respectively mounted and cooperate with each other. The transmission unit is connected to a transmission gear that meshes with the output gear. When the drive motor drives the reducer to run, the output gear of the reducer drives the transmission gear to rotate, which in turn drives the transmission unit to run, so that the transmission unit cooperates with the cutting unit to cut the can lid.

The output gear is connected to the third-stage planetary reduction unit.

[0012] In one embodiment, the first-stage planetary reduction unit includes a first-stage planetary gear set and a first-stage planetary carrier. The first-stage planetary gear set meshes with the input gear and the fixed ring gear, and is connected to the first-stage planetary carrier. A second-stage sun gear is disposed in the middle of the first-stage planetary carrier. The second-stage planetary reduction unit includes a second-stage planetary gear set and a second-stage planetary carrier. The second-stage planetary gear set meshes with the second-stage sun gear and the fixed ring gear, and is connected to the second-stage planetary carrier. A third-stage sun gear is disposed in the middle of the second-stage planetary carrier. The third-stage planetary reduction unit includes a third-stage planetary gear set and a third-stage planetary carrier. The third-stage planetary gear set meshes with the third-stage sun gear and the fixed ring gear, and is connected to the third-stage planetary carrier. The output gear is disposed in the middle of the third-stage planetary carrier.

[0016] In one embodiment, a metal positioning ring is provided on the main body. Beneficial effects

[0017] This utility model relates to an electric can opener, which is driven by a drive motor to operate a reducer. When the reducer is running, it drives the output gear to rotate. Since the output gear meshes with the transmission gear, the transmission gear can also rotate. When the transmission gear rotates, it drives the transmission unit to operate, which in turn cooperates with the cutting unit to cut the can lid. Through the cooperation of the drive motor and the reducer, automated can opening cans can be achieved. The reducer can improve the power transmission efficiency and effectively reduce the noise generated during transmission, thus making the electric can opener more practical and improving the user experience.

[0036] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model 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 full understanding of this utility model. However, this utility model can be implemented 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 this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0038] 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 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.

[0039] Please see Figures 1 to 6 An electric can opener includes a housing 100, a drive motor 200, a reducer 300, a transmission unit 400, and a cutting unit 500. The drive motor 200 and the reducer 300 are respectively disposed inside the housing 100, and one end of the reducer 300 is connected to the output end of the drive motor 200, while the other end is provided with an output gear 310. The housing 100 also contains a main body 110, and the transmission unit 400 and the cutting unit 500 are respectively mounted on the main body 110 and cooperate with each other. The transmission unit 400 is connected to a transmission gear 410 that meshes with the output gear 310.

[0040] Specifically, in this embodiment, when cutting the can lid 810 of the canned product, the can lid 810 is placed between the transmission unit 400 and the cutting unit 500, and then the drive motor 200 is started. The drive motor 200 drives the reducer 300 to run, and the reducer 300 drives the output gear 310 to rotate. Since the output gear 310 is meshed with the transmission gear 410, it can drive the transmission gear 410 to rotate. When the transmission gear 410 is in motion, it drives the transmission unit 400 to run, so that the transmission unit 400 and the cutting unit 500 cooperate to cut the can lid 810. The reducer 300 can improve the power transmission efficiency, and at the same time, it can effectively reduce the noise generated during the transmission between the drive motor 200, the reducer 300, the output gear 310, and the transmission gear 410, thus making the electric can opener more practical and improving the user experience.

[0041] To ensure the reduction transmission effect of the reducer 300, the reducer 300 in this embodiment includes an input gear 320, a fixed gear ring 330, a first-stage planetary reduction unit 340, a second-stage planetary reduction unit 350, and a third-stage planetary reduction unit 360. The fixed gear ring 330 is fixedly connected to the drive motor 200. The first-stage planetary reduction unit 340, the second-stage planetary reduction unit 350, and the third-stage planetary reduction unit 360 are respectively disposed within the fixed gear ring 330 and are sequentially connected for transmission. The input gear 320 is connected to the output end of the drive motor 200 and is also connected for transmission with the first-stage planetary reduction unit 340. The output gear 310 is connected to the third-stage planetary reduction unit 360. The first-stage planetary reduction unit 340 in this embodiment includes a first-stage planetary gear set 341 and a first-stage planetary support 342. Group 341 meshes with input gear 320 and fixed gear ring 330 respectively, and is connected to first-stage planetary carrier 342. Second-stage sun gear 343 is arranged in the middle of first-stage planetary carrier 342. Second-stage planetary reduction unit 350 includes second-stage planetary gear group 351 and second-stage planetary carrier 352. Second-stage planetary gear group 351 meshes with second-stage sun gear 343 and fixed gear ring 330 respectively, and is connected to second-stage planetary carrier 342. Third-stage sun gear 353 is arranged in the middle of second-stage planetary carrier 352. Third-stage planetary reduction unit 360 includes third-stage planetary gear group 361 and third-stage planetary carrier 362. Third-stage planetary gear group 361 meshes with third-stage sun gear 353 and fixed gear ring 330 respectively, and is connected to third-stage planetary carrier 362. Output gear 310 is arranged in the middle of third-stage planetary carrier 362.

[0042] When the drive motor 200 starts, it drives the input gear 320 (i.e., the first-stage sun gear) to rotate. Since the first-stage planetary gear set 341 in the first-stage planetary reduction unit 340 meshes with the input gear 320, it drives the first-stage planetary gear set 341 to rotate. When the first-stage planetary gear set 341 rotates, it drives the connected first-stage planetary carrier 342 to rotate. When the first-stage planetary carrier 342 rotates, the middle second-stage sun gear 343 will also rotate. When the second-stage sun gear 343 rotates, because the second-stage planetary gear set 351 in the second-stage planetary reduction unit 350 meshes with the second-stage sun gear... Gear 343 meshes, thus driving the second-stage planetary gear set 351 to rotate. When the second-stage planetary gear set 351 rotates, it drives the connected second-stage planetary carrier 352 to rotate as well. When the second-stage planetary carrier 352 rotates, the central third-stage sun gear 353 follows suit. When the third-stage sun gear 353 rotates, because the third-stage planetary gear set 361 in the third-stage planetary reduction unit 360 meshes with the third-stage sun gear 353, it drives the third-stage planetary gear set 361 to rotate. When the third-stage planetary gear set 361 rotates, it drives the connected third-stage planetary carrier 362 to rotate as well. When the planetary gear 362 rotates, it will cause the output gear 310 in the middle to rotate as well. Since the transmission gear 410 meshes with the output gear 310 on the third-stage planetary support 362, the rotation of the output gear 310 will drive the transmission gear 410 to rotate. The transmission gear 410 will then drive the transmission unit 400 to operate, thereby enabling the transmission unit 400 to cooperate with the cutting unit 500 to cut the can lid 810. Finally, through the drive motor 200, input gear 320, first-stage planetary reduction unit 340, second-stage planetary reduction unit 350, third-stage planetary reduction unit 360, and output gear 310... The power is transmitted sequentially through the transmission gear 410, thereby ensuring the reduction effect of the reducer 300. At the same time, the reducer 300 can achieve three-stage reduction through the first-stage planetary reduction unit 340, the second-stage planetary reduction unit 350 and the third-stage planetary reduction unit 360, thereby improving the reduction effect. Moreover, the transmission gear 410 is a large gear structure, so it can significantly reduce the torque required by the first-stage planetary reduction unit 340, the second-stage planetary reduction unit 350 and the third-stage planetary reduction unit 360. Even if its output torque is small, it can still drive the transmission gear 410 to rotate, thereby enabling the transmission unit 400 to run.

[0043] Please see Figure 2 and Figure 7The transmission unit 400 includes a gear rod 420, a bushing 430, a spring 440, a wedge sleeve 450, and a pin 460. One end of the gear rod 420 is provided with a gear disc 421, and the other end extends through the main body 110. A limiting hole 422 is opened in the extension section of the gear rod 420. The bushing 430, the spring 440, and the wedge sleeve 450 are respectively sleeved on the gear rod 420, and the bushing 430 and the spring 440 are close to the gear disc 421. The two ends of the spring 440 abut against the bushing 430 and the main body 110, respectively. The wedge sleeve 450 is placed in the extension section and connected to the transmission gear 410. The pin 460 is inserted in the limiting hole 422 to limit the wedge sleeve 450.

[0044] When opening the canned product, the can lid 810 is placed between the transmission unit 400 and the cutting unit 500. The drive motor 420, reducer 300, output gear 310, and transmission gear 410 sequentially drive the wedge sleeve 450 to rotate. As the wedge sleeve 450 rotates, it acts on the pin 460. Through the engagement of the pin 460 and the wedge sleeve 450, the roller rod 420 moves axially, thereby reducing the distance between the transmission unit 400 and the cutting unit 500, thus locking the can lid 810. The transmission gear 410 then continues to drive the wedge sleeve 450 to rotate, which in turn drives the roller rod 420 to rotate. The cutting unit 500 cuts around the can lid 810, and the cutting is completed directly. At this time, since the transmission unit 400 and the cutting unit 500 will grip the can lid 810, the can lid 810 can be directly pried up, separating the can lid 810 from the can body 800 of the canned product. Then, the drive motor 420 drives the reducer 300, the output gear 310 and the transmission gear 410 to rotate in opposite directions in sequence, so that the wedge sleeve 450 will rotate in reverse. The pin 460 will also rotate in reverse. With the reaction force of the spring 440, the toothed rod 420 will move axially to reset. The can lid 810 will fall off under its own weight, and finally the canned product can be opened easily.

[0045] Furthermore, in this embodiment, the bushing 430 is located close to the toothed disc 421. The bushing 430 can effectively improve the stress resistance of the toothed disc 421, thereby increasing the overall service life of the toothed rod 420. Moreover, the bushing 430 is made of engineering plastic material, which can also effectively reduce production costs.

[0046] The wedge sleeve 450 can be integrally formed with the transmission gear 410, or it can be a separate structure; the specific design is not limited. The wedge sleeve 450 can be made of engineering plastic material, which can also effectively reduce production costs. Since the plastic material itself has a certain degree of elasticity, the plastic wedge sleeve 450 can bear the elasticity when opening the can, thereby improving assembly accuracy. It can also enable the electric can open both thicker and thinner can lids 810, thereby improving the user experience.

[0047] In addition, both the limiting hole 422 and the pin 460 are polygonal, and the limiting hole 422 is made by wire cutting process, which can improve the accuracy of the limiting hole 422 and facilitate the processing of the limiting hole 422. The polygonal pin 460 can ensure that it can better cooperate with the wedge sleeve 450.

[0048] Meanwhile, since the wedge sleeve 450 needs to rotate during the can opening process, and in order to reduce the wear between the wedge sleeve 450 and the main body 110, a washer 470 is also fitted on the toothed rod 420. The washer 470 is located between the wedge sleeve 450 and the main body 110. The washer 470 can effectively reduce the wear of the wedge sleeve 450, thereby improving the service life of the electric can opener.

[0049] Of course, in order to achieve the axial movement of the gear rod 420, in this embodiment, two protruding limiting arms are provided at the end of the wedge sleeve 450. The two limiting arms are arranged opposite to each other, and an inclined guide slope is formed between the two limiting arms. When it is necessary to open the can, the transmission gear 410 drives the wedge sleeve 450 to rotate. When the wedge sleeve 450 rotates, the two ends of the pin 460 move from the lowest end to the highest end of the guide slope. When the pin 460 moves, it will drive the gear rod 420 to move. Axial movement is used to reduce the distance between the toothed disc 421 and the cutting unit 500. After the toothed rod 420 moves axially, it can continue to rotate through the limiting arm. After cutting is completed, the transmission gear 410 drives the wedge sleeve 450 to rotate in the opposite direction. The two ends of the pin 460 move from the highest end to the lowest end of the guide slope. The toothed rod 420 is axially reset under the action of the spring 440 to increase the distance between the toothed disc 421 and the cutting unit 500.

[0050] Please see Figure 2 , Figure 8 and Figure 9In order to cut the can lid 810 of the canned product, the cutting unit 500 in this embodiment includes a cutter wheel shaft 510, a support roller 520 and a cutter wheel 530. The main body 110 is provided with a mounting groove 111. The cutter wheel shaft 510 passes through the mounting groove 111. The support roller 520 and the cutter wheel 530 are respectively sleeved on the cutter wheel shaft 510 and located in the mounting groove 111. A limiting notch 112 is provided on the side wall of the mounting groove 111. The side of the support roller 520 is provided with a limiting protrusion 521 corresponding to the limiting notch 112. The support roller 520 and the cutter wheel 530 are both made by stamping process.

[0051] By placing the support roller 520 and the cutter wheel 530 in the mounting groove 111 respectively, and then passing the cutter wheel shaft 510 through the mounting groove 111, the support roller 520 and the cutter wheel 530 are fitted onto the cutter wheel shaft 510, thereby assembling the support roller 520 and the cutter wheel 530, and allowing the cutter wheel 530 to cooperate with the toothed wheel disc 421 of the toothed wheel rod 420, thereby cutting the can lid 810. At the same time, the cutter wheel 530 and the support roller 520 are separate, and the cutter wheel 530 is made by stamping and then precision machining on a lathe, while the support roller 520 is made by stamping. This makes it convenient to process the support roller 520 and the cutter wheel 530, thereby improving the processing efficiency of the cutter wheel 530 and the support roller 520 and reducing production costs.

[0052] Furthermore, in order to improve the service life of the main body 100, a limiting notch 112 is provided on the side wall of the mounting groove 111 of the main body 110, and a limiting protrusion 521 corresponding to the limiting notch 112 is provided on the side of the support roller 520. When the support roller 520 and the cutter wheel 530 are respectively assembled into the mounting groove 111 of the main body 110, the limiting protrusion 521 on the side of the support roller 520 will be placed in the limiting notch 112 of the mounting groove 111. In this way, the support roller 520 is limited by the limiting protrusion 521 and the limiting notch 112, preventing the support roller 520 from rotating with the cutter wheel 530, thereby preventing the support roller 520 from causing wear to the main body 110, ultimately protecting the main body 110 and improving its service life.

[0053] Please see Figures 1 to 5 In order to control the electric can opener, the electric can opener in this embodiment also includes an electrical control unit 600 disposed in the housing 100. The electrical control unit 600 includes a PCB board 610 and a power supply 620. The PCB board 610 can be fixed to the housing 100 with screws, and the power supply 620 can be a built-in battery or an external power supply. When a built-in battery is used, the built-in battery can be mounted on the top of the main body 110, and the power supply 620 and the drive motor 200 are electrically connected to the PCB board 610 respectively. The housing 100 is also provided with a push-button switch 630 for starting / stopping the electrical control unit 600, and a plug interface 640 for charging the built-in battery or for connecting to an external power supply.

[0054] When cutting the can lid 810 of the canned product, double-clicking the button switch 630 causes the PCB board 610 to control the drive motor 200 to rotate forward. The drive motor 200 then drives the input gear 320 to rotate, and transmits power sequentially to the first-stage planetary reduction unit 340, the second-stage planetary reduction unit 350, and the third-stage planetary reduction unit 360. The third-stage planetary reduction unit 360 drives the output gear 310 to rotate. When the output gear 310 rotates, it drives the transmission gear 410 to rotate, which in turn causes the toothed rod 420 in the transmission unit 400 to rotate. The toothed disc 421 of the toothed rod 420 and the cutter wheel 530 in the cutting unit 500 then work together to cut the can lid 810. After cutting is completed, a single click of the button switch 630 causes the PCB board 610 to control the drive motor 200 to rotate in reverse, which in turn causes the toothed rod 420 to rotate in the opposite direction, making it easier to discard the can lid 810 and reset the electric can opener.

[0055] Furthermore, the electric can opener in this embodiment can achieve automatic shutdown control after opening the can: 1. Controlled by current change, i.e., the current is high during operation, and will significantly decrease after the can lid 810 has been cut once. When the circuit detects a significant decrease in current compared to the beginning (e.g., a 30% current reduction), it will issue a command to control automatic shutdown; 2. Controlled by an electronic gyroscope, i.e., when the electronic gyroscope detects that the electric can opener's rotation has completed one revolution and its position coincides with the starting position, it will issue a command to control automatic shutdown. Both of these control methods are existing technologies and will not be elaborated upon further. Ultimately, through intelligent control of the electric can opener, it becomes convenient and simple to use, thereby improving the user experience.

[0056] Please see Figure 1 and Figure 2 To facilitate the assembly of the electric can opener, the housing 100 in this embodiment includes an outer shell 120, a base plate 130, and a lower cover 140. The drive motor 200, reducer 300, main body 110, PCB board 610, and built-in battery are all installed inside the outer shell 120. The base plate 130 and lower cover 140 are then attached to the bottom sides of the outer shell 110 using screw connections and snap-fit ​​connections, respectively. This makes the electric can opener easy to assemble, and after assembly, the overall structure of the electric can opener is reasonable and compact.

[0057] The push-button switch 630 on the top of the housing 120 can easily control the electronic control unit 600, while the plug interface 640 on the side of the housing 120 can easily charge the built-in battery or connect to an external power source.

[0058] Finally, please see Figure 2 and Figure 4To facilitate the use of the electric can opener, in this embodiment, an elastic support 700 is provided on the base plate 130.

The pressure cap 710 covers the top of the mounting hole 131. The elastic element 720 and the top post 730 are respectively disposed in the mounting hole 131, and the two ends of the elastic element 720 abut against the pressure cap 710 and the top post 730. At the same time, a metal positioning ring 113 is provided on the main body 110.

[0059] When the electric can opener is placed on the canned product, the top post 730 of the elastic support 700 and the metal positioning ring 113 will respectively abut against the top of the can lid 810, thus facilitating the placement of the can lid 810 between the transmission unit 400 and the cutting unit 500, thereby facilitating the engagement of the can lid 810 by the transmission unit 400 and the cutting unit 500. After the electric can opener has finished cutting the can lid 810, it can be lifted. During the lifting process, the lever action will compress the top post 730, thereby causing the elastic element 720 in the elastic support 700 (this elastic element can be made of...) to... The can opener uses a compression spring to compress the lid 810, making it easy and effortless to separate the can from the can body 800. After the lid 810 is completely removed, the top post 730 will reset under the elastic force of the elastic element 720, and the lid 810 will be held in place by the toothed wheel 421 and the cutter wheel 530. The lid 810 will not fall off unless the toothed wheel 420 is reversed. Finally, the elastic support 700 and the metal positioning ring 113 make the electric can opener convenient and simple to use, ensuring its practical performance and improving the user experience.
