Description

Technical Field

[0001] The utility model relates to a foam liquid adding structure for a smart toilet. Background Art

[0002] In a smart toilet, the main function of a foam box is to improve the cleaning effect and comfort by generating foam. The foam box mixes the cleaning liquid with air to form foam and releases it through a nozzle, thereby providing a comprehensive hygienic experience. To facilitate adding the cleaning liquid to the foam box, the lid of the smart toilet is usually designed with an adding liquid structure. The liquid inlet of this adding liquid structure is usually arranged on the panel and is equipped with a lid for blocking the adding liquid port to prevent the liquid in the foam box from flowing out.

[0003] In the existing design, in order to maintain aesthetics, the upper end surface of the lid usually adopts an arc-shaped curved surface. The upper end surface of the lid of the adding liquid port is also designed to be adapted to the curvature of the upper surface of the lid. However, this design has some problems. The lid may rotate during use, resulting in the curvature of the lid not matching the arc-shaped curved surface of the lid, thus affecting the overall aesthetics. In addition, the rotation of the lid may interfere with other components, increasing the risk of wear at the contact points. Since the upper surface of the lid needs to be precisely matched with the curvature of the lid, multiple adjustments are often required during installation, resulting in a slow installation process. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a foam liquid adding structure for a smart toilet, which solves the problems that the lid may rotate during use, resulting in the lid no longer matching the curved surface of the lid, and the slow installation speed caused thereby.

[0005] The technical solution adopted by the utility model to solve the above problems is: a foam liquid adding structure for a smart toilet, including a lid, a foam box, and a sealing lid. The lid is connected to the foam box through a pipeline structure. The pipeline structure includes a liquid adding port arranged on the lid. The sealing lid is adapted to the liquid adding port and is detachably installed in the liquid adding port to close the liquid adding port. A first engaging portion is provided on the inner wall of the liquid adding port, and a second engaging portion corresponding to the first engaging portion is provided on the outer wall of the sealing lid. When the sealing lid is installed in the liquid adding port, the first engaging portion and the second engaging portion cooperate to limit the axial rotation of the sealing lid relative to the liquid adding port.

[0006] Compared with the prior art, through the design of the first engaging portion and the second engaging portion, the foam liquid adding structure of the intelligent toilet effectively restricts the axial rotation of the sealing cover relative to the liquid adding port. This design not only reduces the friction between the liquid adding port and the sealing cover, improves the durability and sealing effect of the components, but also simplifies the installation process. The sealing cover can be installed through the direct cooperation of the first engaging portion and the second engaging portion, avoiding the trouble of multiple adjustments during the installation process, thus greatly accelerating the installation speed. These improvements not only enhance the overall performance but also improve the user experience.

[0007] Preferably, the first engaging portion is a sheet-like protrusion extending radially along the liquid adding port diameter, and the second engaging portion is a long strip-shaped notch recessed radially along the sealing cover. When the sealing cover is installed in the liquid adding port, the first engaging portion is inserted into the second engaging portion, and the two side walls of the first engaging portion are in contact with the two side walls of the second engaging portion.

[0008] Preferably, a lug extends radially outward along the edge of the upper end surface of the sealing cover, and a groove corresponding to the lug is provided at the opening edge of the liquid adding port. When the sealing cover is installed in the liquid adding port, the lower end surface of the lug fits with the bottom surface of the groove, and a bevel is provided along the opening edge of the groove. A wedge-shaped gap is formed between the edge of the lug and the bevel.

[0009] Preferably, the pipeline structure further includes a first connecting portion formed by the downward depression of the face cover and a second connecting portion formed by the upward protrusion of the foam box main body. A hollow first pipeline is provided inside the first connecting portion, and the liquid adding port is arranged at the upper end of the first pipeline. The second connecting portion is hollow inside and is provided with a second pipeline communicating with the inner cavity of the foam box main body. The inner wall of the second pipeline is inserted on the outer wall of the first pipeline.

[0010] Preferably, the lower end of the first connecting portion extends axially downward along the first pipeline to form a sealing groove on the outer wall of the first pipeline, and a sealing ring is provided at the bottom of the sealing groove. When the inner wall of the second pipeline is inserted on the outer wall of the first pipeline, the insertion end face of the second pipeline and the first pipeline abuts against the sealing ring.

[0011] Preferably, a tapered connecting surface is provided at the connection between the liquid adding port and the first pipeline for guiding the liquid to flow into the first pipeline. Description of the Drawings
