[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0025] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0027] With reference to the drawings in the specification, a concealed box structure comprises a box body 10 of the concealed box, a bottom plate 20 is provided at the opening at the lower end of the box body, the bottom plate can be made of stainless steel by stamping, a water outlet joint 30 is provided on the bottom plate, the water outlet joint can be made of the original copper part by machining (other processes are also possible); it also comprises a water channel body 40, the water channel body can be a plastic part, which can greatly reduce the cost relative to the copper part, the water channel body is arranged in the box body, the water channel body can be fixed on the bottom plate, so as to ensure the strength of the overall structure, the water outlet 41 of the water channel body can be connected to the water outlet joint, the water outlet and its corresponding water outlet joint are sealed, the water channel body can have multiple water outlets, which can allow water to enter or exit, and the water outlets that are not needed can be blocked by the plug 42 according to actual usage.

[0028] In order to facilitate assembly, disassembly and maintenance, the bottom plate can be detachably connected to the box body, the water channel body can be detachably connected to the bottom plate, and the water flow joint can be detachably connected to the bottom plate, and the components are connected in a splicing manner.

[0029] Referring to the accompanying drawings, the water flow joint is arranged on the outer peripheral side above the bottom plate, and the water channel body is located above the bottom inside the water flow joint.

[0030] Preferably, a through hole 11 is provided on the lower peripheral side wall of the box body. The through hole can communicate with the inner periphery of the box body. One end of the water connection can be inserted from the outer periphery of the box body through the through hole into the box body and connected to the water outlet of the water channel body. The major diameter of the water connection is smaller than the inner diameter of the through hole. A sealing ring 50 is provided between the inner periphery of the through hole and the outer periphery of the water connection. The sealing ring can fix the water connection in the through hole without swinging and also prevent axial movement. This ensures that the entire assembly will not be misaligned when discharging water. It also ensures the coaxiality of the water connection and the water outlet, ensuring that the sealing fit of the inclined surface is very stable.

[0031] Furthermore, the end of the water outlet connector that extends into the box body is provided with a first inclined surface 31, and the water channel body located around the water outlet is provided with a second inclined surface 43. The first inclined surface can be mated with the second inclined surface, and a sealing ring 60 is provided between the first and second inclined surfaces. The first inclined surface slopes downward from top to bottom toward the inside of the box body, and the second inclined surface slopes downward from top to bottom toward the inside of the box body. During use, after the water outlet connector is fixed to the bottom plate, the water channel body is placed into the box body. The mating relationship of the inclined surfaces and the tightening of the screws ensure that the first and second inclined surfaces are in good contact and fit, and then the sealing ring is used to achieve a good end face seal.

[0032] Furthermore, an annular groove 44 is provided on the second inclined surface, and the sealing ring is provided in the annular groove; the sealing ring is provided in the annular groove, and the water channel body is placed in the box body so that the first inclined surface and the second inclined surface are matched and connected.

[0033] In use, the bottom plate is connected to the box body via screws 70, and the water channel body and water outlet joint are connected to the bottom plate via screws 70. The bottom plate is a stainless steel plate, and the water channel body is a plastic part with multiple water channels 45, and the water flow can be connected to the water outlet.

[0034] The utility model changes most of the original parts that were made of copper, so that the whole is supported by a stainless steel bottom plate. The others can be made of lower-cost plastic, which reduces the cost by half. At the same time, the use of a bevel matching method can not only ensure the sealing effect, but also facilitate the disassembly of the water channel body for easy maintenance or replacement.

[0035] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
