In addition, in the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.
[0025] Refer to Figures 1-5 Describe a metal ventilation knife holder according to an embodiment of the present utility model.
[0026] In one embodiment, as Figure 1 and Figure 2 shown, a metal ventilation knife holder includes a knife holder main body. The knife holder main body includes a metal middle frame 1, a front shell 2 and a rear shell 3. The front shell 2 and the rear shell 3 are respectively installed at the front and rear openings of the metal middle frame 1 to form a storage cavity; a knife holder mounting opening 11 for installing a knife holder 4 is provided at the upper part of the metal middle frame 1, and ventilation hole areas 12 are provided on both the left and right sides of the metal middle frame 1.
[0027] Among them, the metal middle frame 1 can be made of, but not limited to, materials such as stainless steel, aluminum alloy, and titanium alloy. Specifically, when implemented, a plurality of suction cups can be provided at the bottom of the metal middle frame 1 to better fix the knife holder main body on the kitchen countertop; the maximum aperture of the ventilation holes in the ventilation hole area 12 does not exceed 6 mm, and the finger width is generally 6 mm. The maximum aperture of the ventilation holes is smaller than the finger width, which is beneficial to ensuring user safety.
[0028] A metal ventilation knife holder in this embodiment can achieve ventilation, mildew prevention and rust prevention by adopting a metal middle frame 1 with symmetric ventilation hole areas 12 on both sides.
[0029] In the above embodiment, a drain pan 5 is provided at the bottom of the storage cavity, and a drain trough opening 13 is opened below one of the ventilation hole areas 12. The drain pan 5 is embedded and installed in the storage cavity through the drain trough opening 13. The drain pan 5 can be pulled out of the storage cavity through the drain trough opening 13 for convenient cleaning.
[0030] In this embodiment, the ventilation hole area 12 is located in the middle of the side plate of the metal middle frame 1, and the ventilation hole area 12 includes at least three kinds of ventilation holes with different apertures; among them, the ventilation hole in the middle of the ventilation hole area 12 has the largest aperture, and the apertures of the ventilation holes in the ventilation hole area 12 gradually decrease from the middle to the upper and lower ends; preferably, the aperture range of the ventilation holes is 2 - 3.8 mm.
[0031] Among them, the ventilation hole area 12 is symmetrically located at the center position on the left and right sides of the metal middle frame 1. The lowest part of the ventilation hole area 12 is higher than the water draining tank opening 13 to ensure the air convection of the ventilation holes to the blade. In the ventilation hole area 12, the upper and lower ventilation holes have small apertures and high strength, which can stabilize the knife holder. The middle ventilation hole has a large aperture and is aligned with the middle of the blade. Since the area in the middle of the blade is the largest and the water accumulation is the most, the middle ventilation hole is larger, and the ventilation effect is better. Specifically in implementation, the aperture range of the ventilation holes can be 2-3.8 mm. For example, in the ventilation hole area 12, from the upper part to the middle part and from the lower part to the middle part, the aperture of the ventilation holes gradually transitions and becomes larger from 2-2.5-3.8 mm.
[0032] In the above embodiment, the layout of the ventilation holes is that the upper and lower apertures are smaller and the middle aperture is larger, which can make the metal middle frame 1 look more beautiful and have a sense of technology and digital. At the same time, the different apertures of the ventilation holes can disrupt the wind speed and reduce the wind noise.
[0033] In this embodiment, as Figure 3 and Figure 4 shown, screw posts 31 are respectively provided at the four corners of the front shell 2 and the rear shell 3. The front shell 2 and the rear shell 3 are fixedly connected through the screw posts 31, and the metal middle frame 1 is clamped between the front shell 2 and the rear shell 3. In the above embodiment, the screw posts 31 are provided at the outermost edges of the four corners of the front shell 2 and the rear shell 3, leaving the middle space in the storage cavity for placing the tool. The front shell 2 and the rear shell 3 are fixed with screws through the screw posts 31, and the metal middle frame 1 is sandwiched between them to form the knife holder main body. This structure is easy to implement, and the shapes of the front shell 2 and the rear shell 3 can be variable.
[0034] In this embodiment, grid-shaped reinforcing ribs 32 are provided on the inner side walls of the front shell 2 and the rear shell 3 facing the metal middle frame 1. In the above embodiment, the front shell 2 and the rear shell 3 are provided with grid-shaped reinforcing ribs 32 with spaced protrusions, which can prevent the plastic shell from deforming during injection molding. At the same time, when there is air flow inside the knife holder main body, the air flow will be blocked by the ribs and will not flow away along the plane, so as to control the air flow to blow towards the middle of the storage cavity, making it easier to blow to the tool and better accelerating the drying of the tool.
[0035] In this embodiment, as Figure 5As shown in the figure, the tool rest mounting opening 11 is a square opening. Two long sides of the square opening are bent inward to form two bent long sides 111. Empty notches 112 are provided at the left and right ends of the bent long sides 111, and the size of the empty notches 112 is not less than 1.5 mm. The panel of the tool rest 4 is provided with an edge part 41, and the side wall of the tool rest 4 is provided with a mounting convex part 42. The tool rest mounting opening 11 is used to clamp the edge part 41, and the bent long sides 111 are in interference fit with the mounting convex part 42 to mount the tool rest 4 onto the tool rest mounting opening 11, realizing the stable mounting of the tool rest 4. In the above embodiment, the short side of the tool rest mounting opening 11 is not bent, and can cooperate with the empty notches 112 at the left and right ends of the bent long sides, facilitating the pulling out of the tool rest 4.
[0036] In this embodiment, two parallel slide rails 51 are provided on both sides of the water draining tray 5. The two slide rails 51 are respectively arranged on the inner side walls of the front shell 2 and the rear shell 3. Guide ribs 511 are provided inside the slide rails 51. The guide ribs 511 include at least one of multiple vertically convex ribs and one horizontally convex rib that are evenly spaced, which can reinforce the slide rails 51 and prevent the slide rails 51 from being deformed during injection molding. Among them, the water draining slot opening 13 is arranged on one side plate of the metal middle frame 1. The two corresponding slide rails 51 of the water draining tray 5 are arranged at positions corresponding to the water draining slot opening 13 on the front shell 2 and the rear shell 3, and the slide rails 51 are integrally connected with the front shell 2 and the rear shell 3.
[0037] In this embodiment, cross beams 52 perpendicular to the slide rails 51 are provided on the inner walls of the front shell 2 and the rear shell 3 on the side far from the water draining slot opening 13. An elastic reset device 53 is provided between the cross beam 52 of the front shell 2 and the cross beam 52 of the rear shell 3. The front end of the elastic reset device 53 abuts against the rear end of the water draining tray 5, and is used for the back-and-forth popping out of the water draining tray 5.
[0038] In this embodiment, the screw posts 31 at the lower corner of the rear shell 3 near the water draining slot opening 13 are located below the slide rails 51 and abut against the bottom surface of the slide rails 51, and the screw posts 31 at the lower corner of the rear shell 3 far from the water draining slot opening 13 are located below the cross beam 52 and abut against the bottom surface of the cross beam 52. In the above embodiment, a screw post 31 is provided below one end of the slide rail 51 close to the water draining slot opening 13, and this screw post 31 is used to support the bottom of the slide rail 51 to prevent the slide rail 51 supporting the water draining tray 5 from being deformed when there is a lot of water in the water draining tray 5. At the same time, a screw post 31 is also provided at the lower part of the cross beam 52 to stabilize the elastic reset device 53 and the water draining tray 5.
[0039] As a preferred implementation manner of this embodiment, both the front shell 2 and the rear shell 3 are made of plastic material; the metal middle frame 1 is a rectangular frame formed by bending a metal plate with rounded corners at the four corners.
