Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a splash plate assembly. Background Art

[0002] Butt welding, also known as butt welding, is a type of resistance welding. Two metal weldments (bars or plates) are clamped in two chucks respectively, and current passes through the connecting ends of the two metal pieces, heating them to a plastic or molten state, and forming a permanent connection under pressure. According to the operation method, it is divided into electric butt welding and flash butt welding. In resistance butt welding, the end faces of the weldments are pre-loaded with axial pressure and kept in close contact before power is applied. When the end bends of the weldments are heated to a plastic state by the current, axial pressure is applied to form a connection. In flash butt welding, the end faces of the weldments are lightly contacted under pre-voltage, and a few contact points melt rapidly under high current density. The high-temperature molten metal splashes out of the gap in the form of sparks (flash). As the two end faces gradually approach, the number and area of ​​contact points gradually increase. When a thin molten layer is formed on the entire end face, axial pressure is quickly applied and power is turned off to form a connection.

[0003] The splash guard assembly is usually arranged below the water outlet of the water purifier. When water drops onto the splash guard assembly, the impact force of the water drops is dispersed by the wire mesh on the splash guard assembly to reduce the splashing water; and in order to ensure that the top surface of the splash guard is smooth and has no sharp protrusions, the wire mesh is usually not installed with screws. However, the wire mesh and the splash guard on the traditional splash guard assembly are usually clamped by an L-shaped clamping arm formed by stamping the bottom end of the splash guard 3. In practice, the wire mesh fixed in this way is less firm, easy to fall off, and is not conducive to mass production. Utility Model Content

[0004] One purpose of the utility model is to solve or alleviate the above technical problems.

[0005] The means adopted by the utility model are as follows: the splash-proof plate assembly comprises a wire mesh, a pressure ring and a splash-proof plate, and the wire mesh, the pressure ring and the splash-proof plate are all made of metal; the wire mesh comprises a plurality of longitudinal wires and a plurality of oblique wires; the longitudinal wires and the oblique wires in the wire mesh are located in the same plane; the wire mesh is provided with an avoidance area; the pressure ring is provided with a pressure ring center opening and a pressure ring convex point; the splash-proof plate is provided with a wire mesh exposed opening; the pressure ring convex point is opposite to the avoidance area and is fixed by butt welding with the bottom end face of the splash-proof plate, so that the bottom end face of the splash-proof plate and the pressure ring clamp the wire mesh, and the wire mesh exists in the overlapping area of ​​the pressure ring center opening and the wire mesh exposed opening.

[0006] The utility model has the effect of improving the overall strength of the splash plate assembly, facilitating batch production of the splash plate assembly and reducing costs.

[0026] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0027] As a specific embodiment, the splash plate assembly of the embodiment of the utility model comprises a wire mesh 1, a pressure ring 2 and a splash plate 3, and the wire mesh 1, the pressure ring 2 and the splash plate 3 are all made of metal. Usually, the wire mesh 1, the pressure ring 2 and the splash plate 3 are all made of stainless steel or the like.

[0028] The wire mesh 1 includes a plurality of longitudinal wires 11 and a plurality of oblique wires 12. The longitudinal wires 11 and the oblique wires 12 are also made of metal, and the longitudinal wires 11 are parallel to each other, and the oblique wires 12 are parallel to each other. The longitudinal wires 11 and the oblique wires 12 are arranged at an angle, and the angle can be set as needed, for example, the angle is set to ninety degrees. The longitudinal wires 11 and the oblique wires 12 in the wire mesh 1 are located in the same plane, but due to the longitudinal wires 11 and the oblique wires 12 themselves, the longitudinal wires 11 and the oblique wires 12 overlap each other (such as Figure 1 There are two metal wires at the intersection of the vertical and horizontal lines shown in the figure, so at least one of the longitudinal wire 11 and the oblique wire 12 is slightly bent, causing a slight bulge in the wire mesh 1 where the longitudinal wire 11 and the oblique wire 12 overlap, but this situation also means that the longitudinal wire 11 and the oblique wire 12 in the wire mesh 1 are located in the same plane.

[0029] The wire mesh 1 is provided with an escape area 13. The escape area 13 is usually formed by setting the length vertical lines of the longitudinal wires 11 and the oblique wires 12, and is not a true circle as shown in the accompanying drawings.

[0030] The pressing ring 2 is provided with a pressing ring center opening 21 and a pressing ring protrusion 22 .

[0031] The splash plate 3 is provided with a wire mesh exposure opening 31. Usually, the outer periphery of the splash plate 3 extends upward to form a splash plate edge 39 to limit the flow range of water on the splash plate 3.

[0032] The pressing ring convex point 22 faces the avoidance area 13 and is fixed to the bottom end surface of the splash plate 3 by butt welding, so that the bottom end surface of the splash plate 3 and the pressing ring 2 clamp the wire mesh 1, and the wire mesh 1 exists in the overlapping area of ​​the pressing ring center opening 21 and the wire mesh exposed opening 31.

[0033] As one of the specific embodiments, the pressing ring convex point 22 is conical as a whole, and the pressing ring 2 is a sheet as a whole. It is easy to understand that the sheet-like pressing ring 2 is jacked up by the top cone to form the pressing ring convex point 22, so the pressing ring convex point 22 also has a conical inner cavity. The pressing ring 2 can be made by punching a metal plate at one time, which can reduce costs, and the elastic pressing ring convex point 22 can ensure the pressure during the butt welding and ensure the butt welding strength.

[0034] As one of the specific implementations, at least one of the longitudinal wire 11 and the oblique wire 12 is fixedly connected with the pressing ring protrusion 22 by butt welding. Figure 7 As shown, before the pressure ring 2 and the splash plate 3 are butt-welded, the wire mesh 1 and the pressure ring 2 are butt-welded into one body to achieve graded butt-welding, which is convenient for mass production and can further improve the strength of the splash plate assembly.

[0035] As one of the specific implementations, the place where at least one of the longitudinal wire 11 and the oblique wire 12 is welded to the convex point 22 of the pressure ring is the part where the longitudinal wire 11 and the oblique wire 12 overlap each other. As mentioned above, at least one of the longitudinal wire 11 and the oblique wire 12 is slightly bent, and the bent part of the longitudinal wire 11 or the oblique wire 12 can be firmly fixed to the pressure ring 2 by welding. The welding of the wire mesh 1 and the pressure ring 2, and the welding of the pressure ring 2 and the splash plate 3 are completed on the same welding equipment, and the utilization rate of the welding equipment is high. The rated power of the welding equipment is low, so it can also reduce the demand for the power supply system to a certain extent.

[0036] As one of the specific implementations, the diameter of the central opening 21 of the pressure ring is smaller than the diameter of the exposed opening 31 of the wire mesh.

[0037] As one of the specific embodiments, the splash plate 3 is plate-shaped, and the splash plate 3 is provided with a side functional groove 38 around the center opening 21 of the pressure ring. The side functional groove 38 can be a through hole for water to pass through, or a convexity on the back of the groove can be formed through the groove to position the pressure ring 2.

[0038] The working principle is that during production, the wire mesh 1 and the pressure ring 2 are first fixed by butt welding, and then the pressure ring 2 with the wire mesh 1 is butt welded to the splash plate 3 at the pressure ring convex point 22. Since the wire mesh 1, the pressure ring 2 and the splash plate 3 are all roughly plate-shaped structures, the wire mesh 1 and the pressure ring 2, the pressure ring 2 and the splash plate 3 are fixed by butt welding in combination with the above structure, which improves the overall strength of the splash plate assembly, facilitates mass production of the splash plate assembly and reduces costs.
