Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen cookers, in particular to a mouth-turned laser cladding anti-rust cooker. Background Art
[0002] The force process of the electric pressure cooker is as follows: the electric pressure cooker is heated to evaporate the water, and pressure is generated inside the inner pot and acts on the lid and the inner pot, causing the lid to move upward and the inner pot and the outer pot to move downward. The lid teeth and the outer pot teeth cooperate with each other to prevent the relative movement of the lid and the outer pot. The root of the outer pot teeth is the main load-bearing part, and the structural strength of the pot teeth depends on the structural strength of the roots of the pot teeth. During the use of the teeth, the teeth are radially embedded in the lid buckle teeth. Long-term use causes the surface of the teeth (especially the contact surface of the upper and lower edges) to wear and cause rust. Of course, even if it is stationary for a long time, it is easy to rust, making it difficult to use with the lid again. Therefore, it is necessary to treat the teeth to achieve daily rust prevention.
[0003] This case was created to solve the above problems. Summary of the invention

[0007] To achieve the above purpose, the utility model is implemented through the following technical scheme: a laser cladding rust-proof cookware with turned teeth at the mouth, including a pot body made of iron or iron-aluminum composite and a flanging structure, the flanging structure is arranged at the open end of the pot body, the flanging structure includes at least one flanging tooth extending radially outward, each flanging tooth is equally spaced, and the flanging tooth is sunken toward the bottom of the outer pot, characterized in that it also includes an extended edge, the extended edge is annular, a notch is opened on the extended edge, a receiving strip is formed at the bottom of the notch, and the flanging tooth is engaged with the receiving strip when it is inserted into the notch, and the vacant space of the adjacent flanging teeth is filled by the extended edge.
[0008] Preferably, the end face of the tooth turning is in contact with an aluminum wire, and laser spraying is used to achieve aluminum layer cladding at the tooth turning.
[0009] Preferably, the end surface of the tooth is pressed against an aluminum rod or a copper rod, and a protective layer is melt-coated by means of rapid rotation and friction.

[0019] The utility model is further described in detail below through the drawings and embodiments.
[0020] like Figure 1-2 Shown is a rust-proof cookware with laser cladding for mouth-flashed teeth, comprising a pot body 1 and a flange structure, wherein the flange structure is arranged at the open end of the pot body 1, and the flange structure comprises at least one flange 2 extending radially outward, wherein the intervals between each flange 2 are equal, and the flange 2 is sunken toward the bottom of the outer pot.
[0021] Generally, iron or iron-aluminum composite pots are used. Since the teeth 2 are radially embedded in the pot cover buckle teeth during use, the surface of the teeth 2 (especially the upper and lower contact surfaces) will be worn and rusted after long-term use (even if it is stationary for a long time, it is easy to rust, making it difficult to use with the cover again). Therefore, it is necessary to spray an aluminum layer on the teeth 2 to prevent rust. The specific method is as follows. Example
[0022] As attached Figure 1 As shown, since the tooth turning part 2 is only partially raised, laser 3 can be used for spraying, and aluminum wire 4 is pressed against the upper and lower surfaces of the tooth turning part 2 where cladding is required, and the aluminum layer is clad in combination with laser 3. Example
[0023] As attached Figure 3-4 As shown, it is difficult to complete uniform surface cladding by using laser 3 in combination with aluminum wire 4. Therefore, this embodiment uses extended edge 5 to fill the gaps of adjacent tooth openings 2, so that the surface of tooth opening 2 is abutted against aluminum rod or copper rod 9, and a protective layer is clad by fast rotation friction (generating a large amount of heat and melting) (of course, laser cladding can still be selectively used after filling the gaps).
[0024] It should be noted that the abutment portion of the aluminum rod or copper rod 9 is divided into positive and negative electrodes (the positive electrode and the negative electrode are energized respectively), which accelerates melting and makes it more compact.
[0025] The extended edge 5 is annular, with a notch 6 formed on the extended edge 5, and a receiving strip 7 formed at the bottom of the notch 6. When the extended edge 5 is embedded in the flange structure, each tooth 2 can be just inserted into the notch 6 and abut against the receiving strip 7. At this time, the upper end of the extended edge 5 at the notch 6 is flush with the end face of the tooth 2, thereby forming a complete annular surface. Figure 5 As shown, the annular surface can be in contact with the aluminum rod or copper rod 9, and a protective layer can be melted and coated by means of rotational friction.
[0026] Furthermore, in order to enable the extended edge 5 to be better used with the pot body 1, an annular cushion (such as conventional silicone material) is provided at the end of the extended edge 5 away from the notch 6, which can be deformed and the inner radial dimension is adapted to the outer diameter of the pot body 1 to achieve a tight hold and fixation of the extended edge 5.
[0027] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
