[0043] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0044] like Figure 1-Figure 7 As shown, the first embodiment provides a two-in-one can opener and knife sharpener, comprising a body 1, on which is provided a can opener mechanism 2 for cutting can lids, a knife sharpening mechanism 3 for sharpening the cutting edge of a tool, and a drive mechanism 4 for driving the can opener mechanism 2 and the knife sharpening mechanism 3 to work, and the drive mechanism 4 is transmission-connected with the can opener mechanism 2 and the knife sharpening mechanism 3 so that the drive mechanism 4 drives the can opener mechanism 2 or the knife sharpening mechanism 3 to work.

[0045] Specifically, the two functions of knife sharpening and can opening are realized by one device, which reduces the trouble of users needing to purchase and store multiple kitchen tools, and saves space and cost; the knife sharpening mechanism 3 is driven by the driving mechanism 4 to grind the knife edge through the rotation of the motor. The sharpening component of the knife sharpening mechanism grinds the knife in a rotating manner through a transmission connection to achieve the effect of a sharp blade; the can opening mechanism 2 is also driven by the driving mechanism 4 to cut the can lid.

[0046] Further, if Figure 4 and Figure 5As shown, the driving mechanism 4 includes a driving motor 401 and a transmission gear assembly 402. The output shaft at one end of the driving motor 401 is connected to the sharpening mechanism 3, the transmission gear assembly 402 is connected to the can opening mechanism 2, and the output shaft at the other end of the driving motor 401 is connected to the transmission gear assembly 402. The driving motor 401 drives the can opening mechanism 2 to rotate through the transmission gear assembly 402.

[0047] Specifically, one end of the output shaft of the driving motor 401 is directly connected to the sharpening mechanism 3, and the rotation of the motor drives the sharpening component of the sharpening mechanism 3 to rotate, thereby realizing the grinding of the tool; the output shaft at the other end of the driving motor 401 is connected to the transmission gear assembly 402, and the power is transmitted to the can opening mechanism 2 through the transmission of the gear. The design of the transmission gear assembly 402 enables the can opening mechanism 2 to obtain sufficient torque and rotation speed to achieve efficient cutting of the can lid.

[0048] Further, if Figure 4 and Figure 5 As shown, the transmission gear assembly 402 includes a driving gear 4021 and a driven gear 4022 , and the axis of the driving gear 4021 and the axis of the driven gear 4022 are arranged perpendicularly.

[0049] Specifically, the output shaft of the driving motor 401 is directly connected to the driving gear 4021. When the driving motor is running, the driving gear 4021 rotates and drives the driven gear 4022 meshing therewith to transmit power to the can opening mechanism 2. The vertical arrangement of the driving gear 4021 and the driven gear 4022 optimizes the internal space layout and meets the actual application requirements.

[0050] It should be noted that the transmission gear assembly 402 includes but is not limited to structures such as bevel gears, spur gears, worm gears or rack and pinion gears, and also has the function of driving the can opening mechanism 2 to work.

[0051] Further, if Figure 4 and Figure 5 As shown, the output shaft at the other end of the driving motor 401 is provided with a first gear 4023 meshing with the driving gear 4021, the driving gear 4021 is provided with a second gear 40211 meshing with the driven gear 4022, and the driven gear 4022 is provided with a transmission shaft 9 connected to the can opening mechanism 2.

[0052] Specifically, one end of the output shaft of the driving motor 401 is directly connected to the sharpening mechanism 3, and a first gear 4023 is provided on the output shaft at the other end. The driving motor 401 drives the driving gear 4021 to rotate through the first gear 4023 to realize power transmission. The driving gear 4021 is provided with a second gear 40211, and the second gear 40211 is meshed with the driven gear 4022. The driven gear 4022 is connected to the can opening mechanism 2 through the transmission shaft 9 to transmit power to the can opening mechanism 2 to complete the can opening operation.

[0053] Further, if Figure 3 and Figure 5 As shown, the can opening mechanism 2 includes a can opening housing 201, on which a connecting shaft 202 is provided. One end of the connecting shaft 202 is cooperatively connected to the transmission shaft 9, and the other end of the connecting shaft 202 is provided with a driving gear 203 for driving the can to rotate.

[0054] Specifically, the connecting shaft 202 accurately transmits the power of the transmission shaft 9 to the driving gear 203, so as to realize the smooth rotation of the can and improve the efficiency and precision of can opening; the driving gear 203 drives the can to rotate by contacting with the can, thereby realizing the can opening operation.

[0055] Further, if Figure 8-Figure 13 As shown, the machine body 1 is provided with a micro switch 6 electrically connected to the drive motor 401, a pushing piece 8 for triggering the contacts of the micro switch 6, and a first switch structure 5 for pushing the pushing piece 8 to trigger the contacts of the micro switch 6, and the can opening mechanism 2 is provided with a second switch structure 7 for pushing the pushing piece 8 to trigger the contacts of the micro switch 6. When the can opening mechanism 2 is installed on the machine body 1, the can opening mechanism 2 locks the first switch structure 5 and triggers the contacts of the micro switch 6 through the second switch structure 7 to drive the drive motor 401 to work; after the can opening mechanism 2 is disassembled from the machine body 1, the contacts of the micro switch 6 are triggered by the first switch structure 5 to drive the drive motor 401 to work.

[0056] Specifically, the two-in-one knife sharpener combines the knife sharpening and can opening functions together, reducing the need for users to purchase additional can openers and saving purchase costs. Through an independent switch structure, it is ensured that the knife sharpening function will not be activated when the can opening function is used, thereby avoiding safety hazards. The first switch structure 5 is located on the body 1 and controls the main switch of the drive mechanism 4. The second switch structure 7 is located on the can opening mechanism 2. When the can opening mechanism 2 is installed, the first switch structure 5 is locked to prevent the first switch structure 5 from being touched to drive the drive mechanism 4 to work, and only the second switch structure 7 on the can opening mechanism 2 is allowed to operate to start the drive mechanism 4 to prevent misoperation. When the can opening mechanism 2 is removed from the body 1, the first switch structure 5 is reactivated, allowing the drive mechanism 4 to work by starting the first switch structure 5, thereby achieving safe operation.

[0057] Further, if Figure 9-12 As shown, the first switch structure 5 includes a first switch button 501 that can slide on the body 1, a linkage rod 502, a guide portion 503 and a lock hook 504 arranged on the first switch button 501, and a step 801 that cooperates with the linkage rod 502 is provided on the pushing piece 8. The first switch button 501 slides back and forth on the body 1 to push the pushing piece 8 to trigger the contacts of the micro switch 6.

[0058] Specifically, the drive motor 401 is responsible for driving the can opening mechanism 2 and the knife sharpening mechanism 3. The drive motor 401 is electrically connected to the micro switch 6 on the body 1 to control the start and stop of the drive motor 401. When the can opening mechanism 2 is not installed, the push member 8 triggers the micro switch 6 by pushing the first switch button 501 to control the drive motor 401 to work and realize the knife sharpening function.

[0059] Further, if Figure 9-12 As shown, the guide portion 503 has a first position 5031 and a second position 5032, a positioning buckle 5033 is provided between the first position 5031 and the second position 5032, a fixing column 102 cooperating with the guide portion 503 is provided on the body 1, the guide portion 503 is located on one side of the linkage rod 502 and extends outward, when the first switch button 501 slides, the guide portion 503 cooperates with the fixing column 102 through the positioning buckle 5033 to position the first switch button 501 at the first position 5031 or the second position 5032, so as to realize that the push member 8 triggers the contact of the micro switch 6 or the push member 8 is away from the contact of the micro switch 6.

[0060] Specifically, due to the manual sliding operation of the user, when the first switch button 501 slides to the first position 5031, the first switch button 501 is positioned at the second position through the cooperation of the positioning buckle 5033 and the fixed column 102, so that the pushing piece 8 triggers the contacts of the micro switch 6 and controls the operation of the drive motor 401; when the first switch button 501 slides to the second position 5032, the positioning buckle 5033 is cooperated with the fixed column 102 to position it at the second position 5032, so that the pushing piece 8 is away from the contacts of the micro switch 6 and the operation of the drive motor 401 is stopped.

[0061] Further, if Figure 9-12 As shown, the lock hook 504 is located on the other side of the linkage rod 502 and extends outward, and a first installation cavity 101 for installing the can opening mechanism 2 is provided on the side portion of one end of the body 1, and a slot 1011 for the lock hook 504 to pass through is provided on the side wall of the first installation cavity 101.

[0062] Specifically, the lock hook 504 cooperates with the can opening mechanism 2 through the slot 1011 on the body 1, so that the can opening mechanism 2 locks the first switch button 501 during installation to prevent it from sliding, thereby ensuring safety.

[0063] Further, if Figure 13-Figure 17 As shown, a rotating handle 204 is provided on the can opener housing 201, and the rotating handle 204 can be rotatably connected to the can opener housing 201. A can opener 206 is also provided on the rotating handle 204. The second switch structure 7 includes a driving rod 701 for pushing the pushing member 8 to trigger the contact of the micro switch 6. When the rotating handle 204 is pressed down, the driving rod 701 pushes the pushing member 8 to trigger the contact of the micro switch 6, and the driving motor 401 works.

[0064] Specifically, the rotating handle 204 is rotatably connected to the can opener housing 201, and a can opener 206 is provided on the handle for actually cutting the can lid.

[0065] Since the height of the can is relatively high, the entire machine body 1 needs to be placed vertically. When the handle 204 is turned and pressed down, the driving rod 701 moves downward, triggering the micro switch 6, so that the driving motor 401 starts to work, and the can is driven to rotate through the transmission shaft 9 and the driving gear 203. The driving gear 203 contacts the can cover by meshing.

[0066] The rotating driving gear 203 drives the can lid to rotate. During the rotation, the can opener 206 cuts the can lid to open the can. After the can lid is completely cut, the user releases the handle or button, the micro switch 6 is disconnected, and the driving motor 401 stops working.

[0067] It should be pointed out that a spring or other reset device may be added to the driving rod 701 to ensure that the driving rod 701 automatically resets after the operation is completed to avoid misoperation.

[0068] Further, if Fig.14 As shown, a guide column 802 is provided on the pushing member 8 , and one end of the driving rod 701 abuts against the end of the guide column 802 .

[0069] Specifically, the guide column 802 is arranged on the pushing member 8, and one end of the driving rod 701 abuts against the end of the guide column 802, ensuring that the driving rod 701 can accurately push the pushing member 8 to trigger the micro switch 6 when the handle 204 is turned and pressed down.

[0070] Further, if Fig.14 As shown, a connecting portion 7011 is provided on the other end of the driving rod 701 , and the rotating handle 204 abuts against the connecting portion 7011 .

[0071] Specifically, when the handle 204 is rotated and pressed downward, the connecting portion 7011 transmits force to the driving rod 701 , thereby pushing the pushing member 8 to trigger the micro switch 6 .

[0072] Further, if Figure 3 and Figure 6As shown, the can opening mechanism 2 is detachably fixedly mounted on the first mounting cavity 101 by means of snaps or magnetic attraction, and a second mounting cavity 104 for mounting the knife sharpening mechanism 3 is provided on the side of the other end of the body 1 .

[0073] Specifically, the can opening mechanism 2 is detachable, so that the user can easily clean and maintain it, thereby improving the hygiene and safety of the product;

[0074] When the can opening mechanism 2 is fixedly installed in the first installation cavity 101 by snap-fitting, a snap-fitting piece is provided on the can opening housing 201, and a slot is provided in the first installation cavity 101 corresponding to the snap-fitting piece. When the can opening mechanism 2 is installed in the first installation cavity 101, the snap-fitting piece cooperates with the slot; it should be noted that there are a plurality of snap-fitting pieces, and the plurality of snap-fitting pieces are evenly spaced and arranged on the can opening housing 201;

[0075] Alternatively, a first magnetic component is disposed on the can opening shell 2011 , and a second magnetic component is disposed in the first installation cavity 101 corresponding to the first magnetic component. When the can opening mechanism 2 is installed in the first installation cavity 101 , the first magnetic component and the second magnetic component are attracted to each other.

[0076] Further, if Figure 6 As shown, the knife sharpening mechanism 3 includes a stopper 301 and one or more grinding wheels 302 for grinding the cutting edge of the knife. The one or more grinding wheels 302 are fixedly mounted on the output shaft at one end of the driving motor 401 through the stopper 301 .

[0077] Specifically, the sharpening mechanism 3 realizes efficient grinding of the tool edge through the limiter 301 and one or more grinding wheels 302. The limiter 301 is used to fix and position the grinding wheel 302 to ensure that the grinding wheel maintains the correct position and angle during the grinding process.

[0078] Further, if Figure 6 As shown, the machine body 1 is provided with a sharpening notch 103 corresponding to the grinding wheel 302 .

[0079] Specifically, the grinding groove 103 provides guidance and support to ensure that the tool maintains a correct angle and position during the grinding process, thereby avoiding edge damage and misoperation.

[0080] Further, if Figure 6 As shown, a drawer box 10 for collecting iron filings generated by the sharpening mechanism 3 is provided on the machine body 1 .

[0081] Second embodiment: This two-in-one can opener and knife sharpener is different from the first embodiment in that a second switch button for pressing the drive rod 701 is provided on the can opener housing 201. When the second switch button is pressed, the push member 8 triggers the micro switch 6 to drive the motor 401 to work.

[0082] Specifically, the second switch button is located above the top of the can opener shell 201. By pressing the drive rod 701, the push member 8 triggers the micro switch 6 to start the drive motor 401. The user presses the second switch button to start the drive motor 401, providing higher operational flexibility.

[0083] The user can choose to start the device by rotating the handle 204 or pressing the second switch button, which provides higher operational flexibility.
