Description

Technical Field

[0001] The utility model relates to the field of knife sharpening devices, in particular to a household knife sharpening device. Background Art

[0002] Kitchen utensils refer to the utensils in the kitchen, such as pots, kitchen knives and other kitchen utensils. Since kitchen knives are essential tools in every household kitchen, the blades of kitchen knives will become blunt or have gaps if they are used for a long time or improperly, so they need to be sharpened to make them sharp again.

[0003] According to a Chinese patent with publication number CN213998783U, a household knife sharpening device is disclosed. The utility model achieves the purpose of knife sharpening through the arrangement of a U-shaped frame, a first motor, a first round rod, a first gear, a second round rod, a second gear and a cylinder, reduces the operation of holding the knife, and avoids injuries to the user due to improper operation.

[0004] Regarding the above-mentioned disclosed patent content, when the tool is sharpened by a cylinder, a large amount of heat will be generated between the tool and the cylinder due to friction, and generally water is added between the tool and the cylinder to cool the tool. However, since the device is an automatic sharpening device, the user may forget to add water to the tool during the sharpening process, making it difficult to cool down the tool and the cylinder in time, which may cause damage to the tool. If water is added to the tool and the cylinder, the water will flow around the device, making subsequent cleaning more troublesome. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a household knife sharpening device to solve the technical problem that the heat generated by the friction between the knife and the cylinder is difficult to dissipate in time.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A household knife sharpening device, such as Figure 1-Figure 6 As shown, it includes a base 1, a support base 13 is installed at the lower part of the base 1, and a lifting component 8 and a heat dissipation component 9 are respectively provided on the support base 13, a driving motor 14 is installed on a mounting plate 12, the output end of the driving motor 14 is connected to a driving shaft 10, and the outer wall of the driving shaft 10 is sleeved with a sharpening cylinder 11. When sharpening is required, the user can start the driving motor 14, and the driving motor 14 can drive the driving shaft 10 to rotate, and the driving shaft 10 will drive the sharpening cylinder 11 to rotate, and the sharpening cylinder 11 can sharpen the knife, and two through grooves 3 are opened at the lower part of the base 1.

[0033] See also Figure 1-Figure 4 Motors 5 are installed on both sides of the base 1. The output end of the motor 5 is connected to a screw rod 2 extending into the through slot 3. When the upper part of the tool needs to be clamped, the user can start the motor 5. The motor 5 can drive the screw rod 2 to rotate. The outer wall of the screw rod 2 is sleeved with a threaded seat 4. A connecting rod 6 is fixed to the top of the threaded seat 4, and one end of the connecting rod 6 is connected to a clamping plate 7. When the screw rod 2 rotates, it will drive the threaded seat 4 to move. After the threaded seat 4 moves, it will drive the connecting rod 6 to move, and then drive the clamping plate 7 to move. When the clamping plate 7 moves, it will clamp the upper part of the tool so as to clamp and fix the tool to prevent the tool from falling down.

[0034] Specifically, the heat dissipation assembly 9 includes a driving gear 901 and a fixing plate 903 installed on the top of the support seat 13. The driving gear 901 is installed on one end of the driving shaft 10. A connecting shaft 904 is connected to the fixing plate 903 through a bearing, and a fan blade 905 is installed at one end of the connecting shaft 904. A driven gear 902 is sleeved on the outer wall of the connecting shaft 904. The driving gear 901 is meshed with the driven gear 902. When the driving shaft 10 continues to rotate, it will drive the driving gear 901 to rotate, and the driving gear 901 will drive the driven gear 902 to rotate, and then drive the connecting shaft 904 to rotate. Two mounting plates 12 are fixed to one side of the top of the support seat 13.

[0035] Specifically, the lifting assembly 8 includes a groove 801 opened on one side of the top of the support seat 13 and a slide rod 807 installed at the middle position of the top of the support seat 13. The outer wall of the slide rod 807 is sleeved with a slide seat 808, and a top plate 805 is installed on one side of the top of the slide seat 808 through a fixed rod 806. When the slide seat 808 moves downward, it will drive the fixed rod 806 to move downward, and then drive the top plate 805 to move downward. After the top plate 805 moves downward, it no longer contacts the bottom of the tool, so as to facilitate subsequent sharpening. The top plate 805 is located on one side of the sharpening cylinder 11, and one end of the screw rod 802 is connected to a turntable. The setting of the top plate 805 is convenient for initial support of the tool, and at the same time, it can make the bottom of the tool flat, avoiding the tool from tilting and causing part of the blade to be difficult to contact with the sharpening cylinder 11.

[0036] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The interior of the groove 801 is connected to a screw rod 802 through a bearing, and a movable seat 803 is sleeved on the outer wall of the screw rod 802. The movable seat 803 is threadedly connected to the screw rod 802. The top plate 805 is slidably connected to the slide rod 807 through a slide seat 808. A rotating plate 804 is connected between the movable seat 803 and the slide seat 808 through a movable shaft. When the screw rod 802 rotates, it will drive the movable seat 803 to move. After the movable seat 803 moves, it will push the rotating plate 804 to rotate, and the rotating plate 804 will drive the slide seat 808 to move, and the slide seat 808 will drive the top plate 805 to move.

[0037] The implementation principle of this embodiment is as follows: first, before using the device, the user can turn on the power supply, and then make the bottom of the tool contact with the top of the top plate 805 so that the tool is placed flat, and then move the tool horizontally so that the blade of the tool contacts the sharpening cylinder 11, and then start the motor 5 to rotate the screw rod 2, thereby driving the threaded seat 4 to move, and then driving the connecting rod 6 to move, and driving the clamping plate 7 to move, so that the clamping plate 7 clamps the upper half of the tool to fix the tool, and then rotate the screw rod 802 to move the movable seat 803 away from the sharpening cylinder 11, and drive the rotating plate 804 to rotate, and the rotating plate 804 pulls the top plate 805 downward to prevent the top plate 805 from affecting the sharpening process of the tool;

[0038] Then start the drive motor 14. The drive motor 14 can drive the drive shaft 10 to rotate, and the drive shaft 10 drives the knife sharpening cylinder 11 to rotate, so that the knife can be sharpened. When the drive shaft 10 continues to rotate, it will drive the active gear 901 to rotate, and the active gear 901 will drive the driven gear 902 to rotate, and then drive the connecting shaft 904 to rotate, and the connecting shaft 904 will drive the fan blades 905 to rotate. The rotation of the fan blades 905 will accelerate the surrounding air circulation speed, so as to dissipate heat between the knife sharpening cylinder 11 and the knife.
