[0002] A knife sharpener is a scientific, practical, efficient and convenient knife sharpening device. An electric knife sharpener is a device that uses electricity to drive a motor to rotate to achieve knife sharpening. It is small in size and easy to operate, and is widely welcomed in home kitchens. However, a knife sharpener can only sharpen knives and has no other functions. When a user needs to open a metal can without a pull ring, the user needs to purchase a can opener to open the can manually or automatically, which requires the user to spend extra money, has a high purchase cost and is not conducive to storage. If a knife sharpener and a can opener are combined together, the safety of the motor-driven knife sharpener or can opener needs to be considered to prevent the motor-driven knife sharpener from working when the can opener is in use, which poses a certain safety hazard.

[0029] 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.

[0030] like Figure 1-Figure 11 As shown, a two-in-one can opener and knife sharpener with high safety is provided, comprising a machine body 1, on which are provided a can opener mechanism 2 for cutting can lids, a knife sharpening mechanism 3 for sharpening the cutting edge of a knife, and a driving mechanism 4 for driving the can opener mechanism 2 and the knife sharpening mechanism 3 to work respectively, a first switch structure 5 for driving the driving mechanism 4 to work is provided on the machine body 1, and a second switch structure 7 for driving the driving mechanism 4 to work is provided on the can opener mechanism 2. When the can opener mechanism 2 is installed on the machine body 1, the can opener mechanism 2 locks the first switch structure 5 and drives the driving mechanism 4 to work through the second switch structure 7; after the can opener mechanism 2 is removed from the machine body 1, the driving mechanism 4 is driven to work through the first switch structure 5.

[0031] Specifically, the two-in-one can opener and 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.

[0032] Further, if Figure 3-Figure 5 As shown, the driving mechanism 4 includes a driving motor 401 , a micro switch 6 electrically connected to the driving motor 401 and a pushing member 8 for triggering the contacts of the micro switch 6 are provided on the body 1 , and the first switch structure 5 includes a first switch button 501 slidable on the body 1 .

[0033] 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.

[0034] Further, if Figure 3-Figure 5 As shown, the first switch structure 5 also includes a linkage rod 502, 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 contact of the micro switch 6, and the linkage rod 502 is set on the first switch button 501.

[0035] Specifically, the first switch button 501 can be slidably installed on the body 1 for manually controlling the operation of the drive mechanism; the linkage rod 502 is arranged on the first switch button 501, and cooperates with the step 801 on the pushing piece 8 to push the pushing piece 8 to trigger the contacts of the micro switch 6, thereby controlling the operation of the drive motor 401.

[0036] Further, if Figure 3-Figure 5As shown, the first switch structure 5 also includes a guide portion 503, 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 arranged 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.

[0037] 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.

[0038] Further, if Figure 7 , Fig. 9 and Fig.10 As shown, the first switch structure 5 also includes a lock hook 504, which is arranged on the other side of the linkage rod 502 and extends outward. 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 groove 1011 for the lock hook 504 to pass through is provided on the side wall of the first installation cavity 101.

[0039] 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.

[0040] Further, if Figure 7 , Figure 9-11 As shown, the can opening mechanism 2 includes a can opening box body 201, and the can opening box body 201 is provided with a guide structure corresponding to the groove 1011 and cooperating with the lock hook 504, the guide structure includes a fixed portion 2011 and an inclined first guide surface 2012, and the lock hook 504 is provided with a second guide surface 5041 cooperating with the first guide surface 2012. When the can opening box body 201 is installed in the first installation cavity 101, the first guide surface 2012 cooperates with the second guide surface 5041 to position the lock hook 504 on the fixed portion 2011.

[0041] Specifically, when the can opening mechanism 2 is installed in the first installation cavity 101 on the body 1, the locking hook 504 passes through the slot 1011, and the first guide surface 2012 cooperates with the second guide surface 5041 to position the locking hook 504 on the fixing portion 2011, locking the first switch button 501, ensuring that the first switch structure 5 cannot drive the drive motor 401 to work, and the drive motor 401 can only be controlled by the second switch structure 7; when the can opening mechanism 2 is removed from the first installation cavity 101 of the body 1, the first switch button 501 is unlocked, and the micro switch 6 is triggered by the linkage rod 502 and the push piece 8 to control the drive motor 401 to work.

[0042] Further, if Figure 6 and Figure 7 As shown, a rotating handle 204 is provided on the can opener box body 201 for pushing the second switch structure 7 to move up and down.

[0043] Specifically, when the can opener box 201 is installed in the first installation cavity 101 , the second switch structure 7 is pushed up and down by the handle 204 to control the start and stop of the drive motor 401 .

[0044] Further, if Figure 7 As shown, 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 handle 204 is turned and 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.

[0045] Specifically, the user presses down and rotates the handle 204, the driving rod 701 pushes the pushing member 8, triggers the micro switch 6, starts the driving motor 401, and the can opening function starts to work.

[0046] Further, if Figure 7 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 .

[0047] 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.

[0048] 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.

[0049] Further, if Figure 7 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 .

[0050] 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 .

[0051] Specifically, the knife sharpening mechanism 3 includes a grinding wheel for grinding the knife blade, and one end of the driving motor 401 is connected to the grinding wheel.

[0052] Furthermore, a transmission gear structure is provided on the other end of the driving motor 401, and the driving motor 401 is connected to the can opening mechanism through the transmission gear structure. The can opening mechanism 2 also includes a can opener and a driving gear. The can opener is arranged on the rotating handle 204, and the driving gear is connected with the transmission gear structure.
