Sealing gasket and water outlet device with same

Abstract

The invention discloses a sealing gasket and a water outlet device with the same. The sealing gasket is used to be installed at a water diversion structure of the water outlet device. The sealing gasket comprises a sealing bottom plate. The sealing bottom plate is provided with a first flow hole and at least one sealing portion. The first flow hole matches with a water inlet hole and a water diversion hole of the water diversion structure. The sealing portions match with the water diversion hole of the water diversion structure. A first side, a position corresponding to the sealing portions, of the sealing bottom plate is provided with a ring-shaped second sealing skirt. The second sealing skirt is used for sealing and matching with the corresponding inner cavity wall of the water diversion structure to prevent the water flow of the water inlet hole flowing to the sealing portions along the first side of the sealing bottom plate. The sealing gasket can reduce the friction force, thereby reducing the switching force when the water outlet device switches the waterway, and has a better user experience, and due to the reduced friction force, the wear speed of the sealing gasket can bereduced to extend the service life of the product.

Description

Technical field [0001] The invention relates to a sealing gasket and a water outlet device with the sealing gasket. Background technique [0002] Existing water outlet devices, such as showers or faucets, generally have a variety of water sprays for users to choose and use. Therefore, the water outlet devices are equipped with a waterway switching structure, and the waterway switching structure mainly uses water splitting. Structure realization. Specifically, the water diversion structure generally includes a first water diversion piece and a second water diversion piece that are relatively movable. The first water diversion piece is provided with water inlet holes, and the second water diversion piece is provided with several water diversion holes. , The first water diversion part is provided with a counterbore at the water inlet hole, and a sealing gasket is provided in the counterbore. The gasket is used to seal and block the water diversion hole that does not correspond to t...

AI Technical Summary

Problems solved by technology

In the existing gasket structure, the sealing skirt 20' and the sealing bottom plate 10' enclose a cavity, and the water entering the cavity through the water inlet hole will flow to the sealing part 12' on the sealing bottom plate 10', so that The sealing part 12' is subjected to water pressure (such as figure 1 The water pressure direction indicated by the middle arrow), the sealing bottom plate 10' receives a larger hydraulic pressure area, resulting in a greater adhesion force of the sealing bottom plate 10' to the second water distribution part, which in turn leads to the switching of the first water distribution part and the second water distribution part. The switching force of the two-part water part needs to be large, the user experience is poor, and it is easy to cause the gasket to wear quickly, and the product service life is short

In addition, in the existing gaskets, in order to keep the gaskets from deformation during use, it is usually necessary to configure a gasket 30' made of a hard material, and the gasket 30' is supported on the non-sealing surface side of the sealing bottom plate 10' , due to the need to set the gasket 30', the structure is more complicated and the cost is larger
