Description

Technical Field

[0001] The utility model relates to the technical field of kitchen utensils, and more particularly to a knife that can be quickly disassembled and assembled. Background Art

[0002] Knives are essential tools in the kitchen. In daily life, as knives are used for a longer time, the blades often become blunt or broken. Currently, blades and knives are usually an integrated structure. When the blade is damaged and needs to be replaced, the intact handle also needs to be replaced, which not only wastes materials but also increases the cost of tool replacement.

[0003] In the prior art, in order to save handle materials and reduce tool replacement costs, tools with detachable blades and handles have appeared on the market. For example, Chinese patent CN218398217U discloses a detachable tool comprising a blade body and a handle. The blade body includes a blade and a connecting handle. The handle is provided with a mounting groove and a plug-in groove. A connecting rod mechanism is inserted into the mounting groove. When the connecting handle is plugged into the plug-in groove, the blade handle is locked or unlocked with the connecting handle through the connecting rod mechanism. However, such a detachable tool requires first installing the connecting rod mechanism in the handle, fixing the relative position of the connecting rod mechanism and the handle, and then inserting the connecting handle into the handle to lock the blade through the connecting rod mechanism. This makes the tool assembly process complicated and the disassembly speed is slow. Utility Model Content

[0004] In order to solve the problems of complex assembly process and slow disassembly speed of detachable cutting tools, the utility model provides a cutting tool that can be quickly disassembled and assembled, simplifies the installation process of the blade and the handle, and realizes the rapid disassembly and assembly of the detachable cutting tool.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A quickly disassembled knife comprises a blade and a handle, wherein the blade is provided with a connecting rod, the handle is provided with a mounting groove for mounting the connecting rod, one side of the mounting groove is provided with a through hole connected thereto, the through hole is provided with a pin for fixing the connecting rod, and the pin is connected to the connecting rod.

[0007] The utility model provides a quickly detachable tool, comprising a blade and a handle, wherein a connecting rod is provided on the blade, a mounting groove is provided in the handle, and a through hole for installing a latch is provided on one side of the mounting groove. When assembling the tool, the connecting rod is inserted into the mounting groove and fixed by the latch, thereby ensuring that the relative position of the blade and the handle does not change, preventing the blade from shaking or falling out of the handle during use. The cooperation of the latch and the connecting rod reduces the operating steps during the blade replacement process, simplifies the installation process of the blade and the handle in the detachable tool, and realizes quick disassembly and assembly between the handle and the blade.

[0008] Furthermore, the connecting rod is provided with a pin hole, through which the pin passes. The pin passes through the pin hole provided on the connecting rod and is connected to the connecting rod. When installing the blade, it is only necessary to align the pin hole with the through hole and then insert the pin, which makes the assembly process convenient and quick.

[0009] Furthermore, a connecting hole is provided in the latch, and the connecting rod passes through the connecting hole. The connecting rod passes through the connecting hole and connects to the latch, which can enhance the fixing effect of the blade in the handle and prevent the blade from shaking, which affects the user experience.

[0010] Furthermore, one end of the connecting hole is provided with an inclined surface, the height of the inclined surface being closer to the blade than the height being farther from the blade, and the connecting rod is provided with a groove that mates with the inclined surface. The inclined surface on the connecting hole mates with the groove on the connecting rod, and the two abut against each other. This prevents the connecting rod from moving horizontally, thereby enhancing the fixing effect. Furthermore, during installation, the connecting rod can be directly inserted, and the pin is moved downward by squeezing the inclined surface, allowing for quick installation of the blade without having to press the pin.

[0011] Furthermore, a positioning groove is provided on one side of the mounting slot and communicates therewith. A first elastic member is disposed within the positioning groove and abuts against the latch. The positioning groove is located at the bottom of the mounting slot and communicates with the mounting slot. The first elastic member disposed in the positioning groove abuts against the latch. This elasticity, during disassembly, propels the latch upward, accelerating disassembly. Furthermore, it increases friction between the connecting rod and the mounting slot, preventing the blade from falling out of the handle.

[0012] Furthermore, a cover for covering the latch is provided on the top of the through hole, which can prevent external oil and dirt from entering the latch connection during use, thereby preventing bacteria from growing.

[0013] Furthermore, a slider and a second elastic member are provided at the end of the mounting slot. The second elastic member is connected to the slider, and the slider abuts against the end of the connecting rod. When the blade needs to be removed for replacement, the second elastic member allows the blade to be quickly ejected from the handle, saving disassembly time. The slider also stabilizes the connection between the second elastic member and the connecting rod, making the assembly and disassembly process smoother.

[0014] Furthermore, the connection between the slider and the connecting rod is a wedge-shaped structure. The wedge-shaped structure can make the connection between the slider and the connecting rod more stable and enhance the fixing effect of the blade in the horizontal direction.

[0015] Furthermore, the knife handle is equipped with a switch, a sterilizing lamp, and a controller. The switch is located on the surface of the knife handle, and a cavity is provided within the handle. The controller is located within the cavity. The sterilizing lamp is located on the surface of the knife handle near the blade. The switch is connected to the controller via a wire, and the controller is connected to the sterilizing lamp via a wire. The user controls the controller via the switch on the handle surface, and the controller transmits a signal to the sterilizing lamp via the wire to adjust the operating state of the sterilizing lamp. During the food processing process, the sterilizing lamp can disinfect and sterilize the food surface. Turning on the sterilizing lamp when cleaning the knife can also ensure the cleaning effect of the blade surface.

[0016] Furthermore, the controller includes a battery, a PLC circuit board, and a charging port. The charging port is located on the surface of the handle, and the PLC circuit board is connected to the battery and the charging port via wires. The PLC circuit board controls signal transmission between the switch and the sterilization lamp beads. An external power supply charges the battery through the charging port, and the battery provides power for the normal operation of the PLC circuit board and the sterilization lamp beads.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Simplifies the installation process of the blade and the tool handle, realizes the rapid disassembly and assembly of the detachable tool, and reduces the cost of tool replacement;

[0019] 2. The knife handle has a sterilization function, which can kill germs on the surface of the food and the knife when processing food or cleaning the knife. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1

[0030] like Figure 1As shown, this embodiment provides a quickly detachable knife, comprising a blade 1 and a handle 2. The blade 1 is provided with a connecting rod 11, and the handle 2 is provided with a mounting groove 21 for mounting the connecting rod 11. A through hole 211 is provided on one side of the mounting groove 21 and connected thereto. A latch 22 is provided in the through hole 211 for securing the connecting rod 11, and the latch 22 is connected to the connecting rod 11. During assembly of the detachable knife, the connecting rod 11 on the blade 1 is first inserted into the mounting groove 21, and then the latch 22 is inserted into the through hole 211. The engagement between the latch 22 and the connecting rod 11 secures the position of the blade 1, ensuring that the blade 1 does not fall off the handle 2 and does not shake during use. When the blade 1 or the handle 2 needs to be replaced, the latch 22 is first removed from securing the connecting rod 11. After removing the latch 22, the blade 1 can be quickly separated from the handle 2. The latch 22 of this embodiment is installed inside the handle 2 through the through hole 211. This does not add complexity to the outer surface of the handle 2, making it less susceptible to dirt and grime, and simplifying the cleaning of the tool. The latch 22 cooperates with the connecting rod 11 to enable quick installation and removal of the blade 1 and handle 2, simplifying the installation process. If the blade 1 or handle 2 is damaged, they can be replaced separately without having to be discarded as a whole, thus reducing tool replacement costs.

[0031] In this embodiment, a latch hole can be provided on the connecting rod 11, and the latch 22 passes through the latch hole to fix the relative position of the connecting rod 11 and the handle 2. When installing the blade 1, it is only necessary to align the latch hole with the through hole 211 and then insert the latch 22. The assembly process is convenient and fast, and the fixing effect is good. In this embodiment, a connecting hole 221 can also be provided in the latch 22, and the connecting rod 11 passes through the connecting hole 221. Figure 2 、 Figure 3 As shown. The through hole 211 is located on the surface of the handle 2 and is connected to the mounting groove 21. When the user installs the blade 1, he only needs to press the pin 22 at the through hole 211 to align the connecting hole 221 with the connecting rod 11, and then pass the connecting rod 11 through the connecting hole 221 and install it in the handle 2. The operation is simple and convenient. A bevel 222 is provided at one end of the connecting hole 221. The height of the bevel 222 close to the blade 1 is less than the height of the side away from the blade 1. A groove corresponding to the shape of the bevel 222 is provided on the connecting rod 11. When the blade 1 is inserted into the bevel 222 at one end of the connecting hole 221, the connecting rod 11 squeezes the bevel 222 to cause the pin 22 to move downward, thereby achieving quick installation of the blade 1 without pressing the pin 22. After the blade 1 is installed, the groove at the corresponding position is engaged with the bevel 222 to fix the blade 1 in the horizontal direction.

[0032] like Figure 2As shown, in this embodiment, one side of the mounting slot 21 is provided with a positioning slot 212 that communicates therewith. A first elastic member 23 is provided within the positioning slot 212, which abuts against the latch 22. The first elastic member 23 can be a spring, elastic sheet, or other component, and its original length should be greater than the depth of the positioning slot 212. After the connecting rod 11 is inserted into the mounting slot 21, the first elastic member 23 is compressed, which pushes up the latch 22, increasing the pressure and friction between the connecting rod 11 and the mounting slot 21, thereby improving the fixing effect between the blade 1 and the handle 2. When the blade 1 needs to be replaced, the latch 22 is first pressed, compressing the first elastic member 23, releasing the fixation between the latch 22 and the connecting rod 11, and the blade 1 can be removed. The first elastic member 23 then pushes the latch 22 upward, allowing it to be quickly removed.

[0033] In this embodiment, a cover is provided on the top of the through hole 211 to cover the latch 22. The cover is installed above the latch 22 to prevent oil from splashing into the latch 22 during use of the tool and to prevent bacteria from growing at the connection of the latch 22.

[0034] Example 2

[0035] like Figure 2 As shown, this embodiment is similar to the first embodiment, except that a slider 24 and a second elastic member 25 are provided at the end of the mounting groove 21 in this embodiment. The second elastic member 25 is connected to the slider 24, and the slider 24 abuts against the end of the connecting rod 11. The second elastic member 25 can be a spring, an elastic sheet, or other parts. When the connecting rod 11 is inserted into the mounting groove 21, the second elastic member 25 is compressed. When the blade 1 needs to be removed for replacement, the latch 22 is first pressed. With the cooperation of the inclined surface 222 and the groove, the fixation between the latch 22 and the connecting rod 11 is released, and the second elastic member 25 ejects the slider 24 and the connecting rod 11 outward, quickly completing the disassembly of the blade 1 and the handle 2.

[0036] like Figure 2As shown, the connection between the slider 24 and the connecting rod 11 in this embodiment is a wedge-shaped structure. A first downwardly inclined surface is provided at the end of the connecting rod 11, and a protrusion is provided on the slider 24. A second inclined surface is provided on the protrusion to cooperate with the first inclined surface. The first inclined surface and the second inclined surface cooperate to form a stable wedge-shaped structure. When the slider 24 ejects the connecting rod 11 outward, the slider 24 generates a force perpendicular to the second inclined surface on the connecting rod 11. This force can be decomposed in the horizontal direction and the vertical direction. The horizontal force can help the connecting rod 11 quickly escape from the shank 2, and the vertical force can increase the pressure between the connecting rod 11 and the mounting groove 21, thereby increasing friction and avoiding the danger caused by the too rapid ejection process. When the connecting rod 11 is installed in the mounting groove 21, the first inclined surface abuts the second inclined surface, and the force exerted by the slider 24 on the connecting rod 11 can also be decomposed in the horizontal direction and the vertical direction. The horizontal force causes the groove on the connecting rod 11 to abut the pin 22, and the vertical force increases the friction between the connecting rod 11 and the mounting groove 21, thereby improving the fixation of the blade 1 in the handle 2 and optimizing the user experience. The wedge-shaped structure here can also be configured as a protrusion provided at the end of the connecting rod 11, with a first upwardly inclined surface provided at the protrusion, and a second inclined surface provided on the slider 24 to cooperate with the first inclined surface, which can also play a role in strengthening the fixation effect during installation.

[0037] Example 3

[0038] like Figure 4 As shown, this embodiment is similar to the second embodiment, except that the handle 2 of this embodiment is provided with a switch 26, a sterilizing lamp 27, and a controller 28. The switch 26 is located on the surface of the handle 2, and a chamber 29 is provided inside the handle 2. The controller 28 is located within the chamber 29. The sterilizing lamp 27 is located on the surface of the handle 2 near the blade 1. The switch 26 is connected to the controller 28 via a wire, and the controller 28 is connected to the sterilizing lamp 27 via a wire. The switch 26 can be configured as a touch switch, a key microswitch, or a knob switch. When the user wishes to activate the sterilizing lamp 27 for sterilization while preparing food, cleaning knives, or storing knives, they can directly operate the switch 26 located on the surface of the handle 2. The switch 26 instructs the controller 28 to activate the sterilizing lamp 27, killing germs on the surfaces of the food and the blade 1. The sterilizing lamp 27 can be a light wave disinfection lamp or an ultraviolet disinfection lamp. The sterilizing lamp 27 is located on the surface of the handle 2 near the blade 1, irradiating the surface of the blade 1 for disinfection.

[0039] The controller 28 in this embodiment includes a battery 281, a PLC circuit board 282, and a charging port 283. The charging port 283 is located on the surface of the handle 2, and the PLC circuit board 282 is connected to the battery 281 and the charging port 283 via wires. An external charging device charges the battery 281 through the charging port 283, and the battery 281 stores the energy to power the PLC circuit board 282 and the sterilization lamp 27. The charging port 283 can be a USB Type-C or Micro USB port, compatible with most commercially available electronic device chargers, eliminating the need for a dedicated charger. The knife in this embodiment features both rapid assembly and sterilization capabilities. A detachable structure is provided at one end of the handle 2 for connecting to the blade 1, and a cavity 29 is provided at the other end for accommodating the battery 281, PLC circuit board 282, and charging port 283. This integration of rapid assembly and sterilization capabilities within the handle 2 reduces tool replacement costs and improves hygiene during food handling.
