[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0035] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0036] like Figure 1 As shown, the present invention provides a kitchen knife, comprising: a power-assisting mechanism 2, which is movably arranged on the back of the kitchen knife body 1, and the power-assisting mechanism 2 is used to impact the back of the kitchen knife body 1, so that the user uses the kitchen knife body 1 to cut hard objects.

[0037] The working principle of the above technical solution is: when the user uses the kitchen knife body 1 to cut hard objects (pork bones, pumpkins), the user places the blade of the kitchen knife body 1 at the position to be cut, and then uses the power-assisting mechanism 2 to impact the back of the knife body 1, and then transmits the impact force of the power-assisting mechanism 2 to the kitchen knife body 1 to cut the hard object. Of course, this process may require the user to use the power-assisting mechanism 2 to impact the kitchen knife body 1 multiple times. This depends on the user's personal strength. On the whole, it is much safer than using the hand to directly impact the knife cap, and it will not cause hand pain or injury. In addition, the effect of transmitting force is also much better than using the knife cap.

[0038] Beneficial effects of the above technical solution: The present invention provides a kitchen knife, on which a power-assisting mechanism 2 is designed to replace the user's direct impact on the knife cap with hands, which is safe and will not cause hand pain or injury. In addition, the transmission effect of the power-assisting mechanism 2 on the kitchen knife body 1 is much better than the transmission effect of using the knife cap.

[0039] like Figure 1 , Figure 2 As shown, in one embodiment, the kitchen knife body 1 includes a knife body 11 and a reinforcing plate 12 disposed on the back of the knife body 11, wherein the thickness of the reinforcing plate 12 is greater than the thickness of the knife body 11, so that the back of the knife body 1 is a T-shaped protrusion;

[0040] The power assist mechanism 2 includes a guide rod 21 and an impact block 22 . The guide rod 21 is connected to the reinforcing plate 12 . A guide through hole 20 is provided in the impact block 22 , so that the impact block 22 is slidably disposed on the guide rod 21 and is used to impact the reinforcing plate 12 .

[0041] The working principle of the above technical solution is as follows: when the user uses the power-assisting mechanism 2, the guide rod 21 is first connected to the reinforcing plate 12. There is a guide through hole 20 in the impact block 22, so it can be sleeved on the guide rod 21. The user holds the impact block 22 with his hand and impacts the reinforcing plate 12 downward along the guide rod 2. The reinforcing plate 12 transmits the impact force to the knife body 11, thereby realizing the impact of the power-assisting mechanism 2 on the kitchen knife body 1, so that the kitchen knife body 1 can easily cut off hard objects. Among them, the thickness of the reinforcing plate 12 is greater than the thickness of the knife body 11, so that the back of the kitchen knife body 1 is a T-shaped protrusion, and the reinforcing plate 12 plays a role in protecting the knife body 11 and preventing the impact block 22 from damaging the knife body 11.

[0042] Beneficial effects of the above technical solution: Through the design of the above structure, the specific structure of the kitchen knife body 1 and the power-assisting mechanism 2 is provided in this embodiment, which is convenient to use. The impact block 22 impacts the reinforcing plate 12, protects the knife body 11 and makes it more convenient for users to use the kitchen knife of the present invention to cut hard objects.

[0043] like Figure 2 As shown, in one embodiment, the impact block 22 includes an impact disk 221 and an impact column 222, the impact column 222 is connected to the impact disk 221, the diameter of the impact disk 221 is larger than the diameter of the impact column 222, and the guide through hole 20 passes through the impact disk 221 and the impact column 222 from top to bottom.

[0044] The working principle of the above technical solution is as follows: the impact block 22 includes an impact disc 221 and an impact column 222, wherein the diameter of the impact disc 221 is larger than the impact column 222, so that the user's hand holds the impact column 222, and the impact disc 221 plays a role of protecting the hand, and the impact disc 221 directly impacts the kitchen knife body 1 instead of the hand; a guide through hole 20 is designed in the impact column 222, so that the impact block 22 passes through the guide through hole 20 along the guide rod 21 to impact the kitchen knife body 1.

[0045] Beneficial effects of the above technical solution: Through the design of the above structure, the specific structure of the impact block 22 is provided in this embodiment. The structure is simple and easy to manufacture. The impact plate 221 and the impact column 222 provide an impact force for the kitchen knife body 1.

[0046] like Figure 3 , Figure 4 As shown, in one embodiment, two connecting plates 13 are provided on the reinforcing plate 12, and the connecting plates 13 are provided with first connecting holes 14, and the lower end of the guide rod 21 is provided with a second connecting hole 23 corresponding to the first connecting hole 14, and is connected through a connecting member 3;

[0047] A first groove 223 communicating with the guide through hole 20 is disposed at the bottom of the impact disk 221 . The first groove 223 is used to receive the connecting plate 13 , so that the lower end of the impact disk 221 directly impacts the upper surface of the reinforcing plate 12 .

[0048] The working principle of the above technical solution is as follows: in order to install the guide rod 21 on the kitchen knife body 1, two connecting plates 13 are designed on the reinforcing plate 12, a first connecting hole is opened on the connecting plate 13, and a second connecting hole 23 is opened at the lower end of the guide rod 21, so the user can first pass the lower end of the guide rod 21 through the guide hole 20, that is, install the impact block 22 on the guide rod 21, and then insert the lower end of the guide rod 21 between the two connecting plates 13, so that the second connecting hole 23 is aligned between the two first connecting holes 13, and then use the connecting piece 3 to connect to the first connecting hole 13 and the second connecting hole 23, so that the guide rod 21 is connected to the reinforcing plate 12.

[0049] Beneficial effects of the above technical solution: Through the design of the above structure, this embodiment provides components such as a connecting plate 13, a first connecting hole 14, a second connecting hole 23 and a connecting piece 3, which makes it convenient for users to connect the guide rod 21 to the kitchen knife body 1, thereby facilitating users to use the kitchen knife of the present invention.

[0050] like Figure 3 , Figure 4As shown, in one embodiment, a second groove 15 is provided on the reinforcing plate 12, and the second groove 15 is located between the two connecting plates 13. A third connecting hole 24 is also provided at the lower end of the guide rod 21, and the third connecting hole 24 is located on the right side of the second connecting hole 23, wherein the lower end of the guide rod 21 can be inserted into the second groove 15, so that the second connecting hole 23 is located in the second groove 15, and the third connecting hole 24 is connected to the first connecting hole 14 through the connecting member 3.

[0051] The working principle of the above technical solution is: the user uses the connecting piece 3 to connect the guide rod 21 to the reinforcing plate 21, but the guide rod 21 and the connecting plate 13 are detachably connected, and it is inevitable that the connection is not reliable, resulting in relative rotation between 21 and the connecting plate 13, which will be unsafe for the user to use. Therefore, a second groove 15 is provided on the reinforcing plate 12, and the second groove 15 is located between the two connecting plates 13, and a third connecting hole 24 is designed at the lower end of the guide rod 21 and on the left side of the second connecting hole 23. Therefore, the user inserts the guide rod 21 into the second groove 15, and the second connecting hole 23 is located in the second groove 15, so that the third connecting hole 24 is aligned with the first connecting hole 14, and the user then uses the connecting piece 3 to connect the first connecting hole 14 and the third connecting hole 24, so that the guide rod 21 is stably fixed on the kitchen knife body 1, and the user uses the impact block 22 to impact the kitchen knife body 1.

[0052] Beneficial effects of the above technical solution: Through the design of the above structure, the second groove 15, the third connecting hole 24 and other structures are provided in this embodiment, so that the guide rod 21 can be stably fixed on the kitchen knife body 1, thereby increasing the stability and safety of the kitchen knife of the present invention in the use process.

[0053] like Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment, the guide rod 21 is configured as a telescopic guide rod, and the guide rod includes an inner core rod 211, a first inner tube 212, a second inner tube 213 and an outer tube 214, the second connecting hole 23 and the third connecting hole 24 are sequentially arranged at the left end of the inner core rod 211, the first inner tube 212 is slidably mounted on the inner core rod 211, the second inner tube 213 is slidably mounted on the first inner tube 212, and the outer tube 214 is slidably mounted on the second inner tube 213.

[0054] The working principle of the above technical solution is as follows: in order to increase the impact force of the impact block 22 impacting the kitchen knife body 1, the guide rod 21 is designed as a telescopic guide rod, that is, the guide rod 21 includes an inner core rod 211, a first inner tube 212, a second inner tube 213 and an outer tube 214. The user can arbitrarily extend or contract the first inner tube 212, the second inner tube 213 and the outer tube 214, so that the overall length of the guide rod 21 is increased, and the impact stroke of the impact block 22 is also increased, and then the impact force of the impact block 22 impacting the kitchen knife body 1 along the guide rod 21 is greatly improved, so that the kitchen knife body 1 can cut hard objects more easily.

[0055] Beneficial effects of the above technical solution: Through the design of the above structure, a specific structure of the guide rod 21 is provided in this embodiment, so that the guide rod 21 can be increased in length, and the impact stroke of the impact block 22 is also increased, and then the impact force of the impact block 22 along the guide rod 21 to impact the kitchen knife body 1 is greatly improved, making it easier for the kitchen knife body 1 to cut hard objects.

[0056] like Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment, a fixing screw 26 is also provided on the guide rod 21, a first threaded hole 215 is provided at the right end of the inner core rod 211, a threaded sleeve 216 is provided at the left end of the outer tube 214, and a screw body 261 of the fixing screw 26 can selectively pass through the threaded sleeve 216 to be connected to the first threaded hole 215, and a diameter of a screw cap 262 of the fixing screw 26 is larger than an outer diameter of the outer tube 214.

[0057] The working principle of the above technical solution is as follows: when the guide rod 21 is retracted, in order to prevent the first inner tube 212, the second inner tube 213 and the outer tube 214 from sliding correspondingly with the inner core rod 211, and to ensure that the guide rod 21 is relatively stable in the retracted state, a fixing screw 26 is also provided on the guide rod 21, a first threaded hole 215 is provided at the right end of the inner core rod 211, and a threaded sleeve 216 is provided at the left end of the outer tube 214. When the user retracts the inner core rod 211, the first inner tube 212, the second inner tube 213 and the outer tube 214 together, the screw body 261 of the fixing screw 26 is screwed together with the threaded sleeve 216 and the first threaded hole 215;

[0058] In addition, when using the impact block 22, the fixed screw 26 can be installed separately on the outer tube 214. The diameter of the screw cap 262 of the fixed screw 26 is larger than the outer diameter of the outer tube 214, so that the screw cap 262 can block the impact block 22 and prevent the impact block 22 from sliding off the guide rod 21, further increasing safety.

[0059] Beneficial effects of the above technical solution: Through the design of the above structure, the present embodiment provides a specific structure of the fixed screw 26, as well as structures such as the first threaded hole 215 and the threaded sleeve 216, so that the guide rod 21 can be stably retracted, and when the impact block 22 is in use, the screw cap 262 can play a role in blocking the impact block 22, preventing the impact block 22 from sliding off the guide rod 21, thereby further increasing safety.

[0060] like Figure 1 , Figure 8 , Fig.11 As shown, in one embodiment, the kitchen knife body 1 further includes a handle 16, the handle 16 includes a handle body 161, and a connecting block 162 disposed below the left end of the handle body 161, and a T-shaped groove 163 extending to the right is disposed at the left end of the connecting block 162, and the T-shaped groove 163 corresponds to the T-shaped protrusion, so that the knife body 11 and the reinforcing block 12 are inserted into the connecting block 162;

[0061] The handle body 161 is provided with an accommodating through hole 164, and the guide rod 21 can pass through the through hole 164. The screw cap 262 of the fixing screw 26 abuts against the right end of the handle body 161. The diameter of the screw cap 262 of the fixing screw 26 is larger than the diameter of the through hole 164, so that the handle 161 is fixed on the kitchen knife body 1.

[0062] The working principle of the above technical solution is as follows: Figure 1 As shown, when the kitchen knife body 1 is in use, there is no handle 16, that is, compared with common kitchen knives, the kitchen knife of the present invention can be used with only the kitchen knife body 1 and the power-assisting mechanism 2;

[0063] Since the guide rod 21 is separated from the kitchen knife body 1, that is, it is very time-consuming to install the guide rod 21 on the kitchen knife body 1 every time the power-assist mechanism 2 is used, the guide rod 21 needs to be stored in the kitchen knife body 1, so a handle 16 is provided, the handle 16 includes a handle body 161 and a connecting block 162, the left end of the connecting block 162 is provided with a T-shaped groove 163 extending to the right, and the handle body 161 is provided with a receiving through hole 164. The user sleeves the handle 16 on the guide rod 21, so that the knife body 11 and the reinforcing plate 12 in the kitchen knife body 1 can be installed. In the T-shaped groove 163, the guide rod 21 is then retracted, and the screw body 261 of the fixed screw 26 is screwed together with the threaded sleeve 216 and the first threaded hole 215. The screw cap 262 is pressed against the right end of the handle body 161. The diameter of the screw cap 262 of the fixed screw 26 is larger than the diameter of the through hole 164, which prevents the handle 16 from coming off the knife body 11. That is, the handle 16 is installed on the kitchen knife body 1, so that the handle 16 plays the role of storing the guide rod 21 and can also be held and used by the user, so that the kitchen knife body 1 can be used like a common kitchen knife.

[0064] Beneficial effects of the above technical solution: Through the design of the above structure, a specific structure of the handle 16 is provided in this embodiment. The handle 16 can store the guide rod 21 and can also be held by the user for use, so that the kitchen knife body 1 can be used like a common kitchen knife, which increases the practicality of the kitchen knife body 1 and avoids time-consuming connection between the guide rod 21 and the kitchen knife body 1.

[0066] Two third grooves 121 are provided at the bottom of the reinforcing plate 12, and the two third grooves 121 are respectively located on both sides of the blade body 11. An ultraviolet light strip 122 is provided in the third groove 121. A fourth groove 123 is provided at the end of the reinforcing plate 12. A second magnetic conductive head 124 electrically connected to the ultraviolet light strip 122 is provided in the fourth groove 123. The second magnetic conductive head 124 is selectively electrically connected to the first magnetic conductive head 168.

[0067] The working principle of the above technical solution: in order to increase the disinfection function of the kitchen knife of the present invention, the kitchen knife can be automatically disinfected when it is not in use, two third grooves 121 are arranged at the bottom of the reinforcing plate 12, and the two third grooves 121 are respectively located on both sides of the knife body 11, and an ultraviolet light bar 122 is arranged in the third groove 121, and a second magnetic conductive head 124 is designed at the end of the reinforcing plate 12. When the handle 16 is installed on the kitchen knife body 1, the second magnetic conductive head 168 in the handle 16 contacts the second magnetic conductive head 124, so that the battery 166 can supply power to the ultraviolet light bar 122, and the ultraviolet light bar 122 can emit deep ultraviolet light to disinfect the surface of the knife body 11. Since the deep ultraviolet light emitted by the ultraviolet light bar 122 irradiates the knife body 11, the disinfection effect is better;

[0068] The right side wall of the connecting block 162 is provided with a charging port 167 for charging the battery 166 . Of course, a switch (not shown) is also designed on the connecting block 162 .
