Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom products, specifically relating to a shower head. Background Technology

[0002] To change the water flow pattern, showerheads typically have a spray grille at the outlet. This grille is adjusted by rotating or pressing to change the water flow and create different water spray patterns. However, because the spray grille has small, dense mesh, it easily accumulates limescale or becomes clogged with impurities after prolonged use. This can lead to uneven water flow, distorted water spray, and compromised water cleanliness. Solving these problems usually requires disassembling the showerhead and cleaning the spray grille with descaling agents and other cleaning tools. However, current showerheads generally have complex structures, making the disassembly and reassembly of the spray grille inconvenient and hindering cleaning. Summary of the Invention

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0024] See Figures 1-6 This embodiment discloses a shower head, which includes an outer casing 10 and a built-in nozzle. The outer casing 10 includes a water inlet end 11 and a water outlet end 12 that are connected.

[0025] The built-in nozzle includes a built-in ring 20 and a spray seat 30. The built-in ring 20 is detachably embedded inside the water outlet 12. The built-in ring 20 defines a water outlet cavity. The spray seat 30 is rotatably assembled in the water outlet cavity. The spray seat 30 includes an outer wall 33 and a first spray plate 31 and a second spray plate 32 respectively assembled on the top and bottom of the outer wall 33. The spray seat 30 can be flipped relative to the built-in ring 20 to change the position of the first spray plate 31 and the second spray plate 32. A water outlet is provided at the bottom of the water outlet cavity. The diameter of the water outlet is smaller than the maximum outer diameter of the spray seat 30 to prevent the spray seat 30 from accidentally falling off under the impact of water flow or its own weight.

[0026] The outer casing is a conical casing, with the water inlet 11 located at the smaller end and the water outlet 12 located at the larger end. The inner wall of the water outlet 12 is formed with an internal thread, and the middle section of the outer ring wall 22 is formed with an external thread 222 that screws into the internal thread. The inner ring 20 includes an inner ring wall 21 and an outer ring wall 22. The bottom of the outer ring wall 22 is provided with recessed grooves 221 spaced apart circumferentially, forming an operating gap between the recessed grooves 221 and the inner wall of the outer casing. The recessed grooves 221 are symmetrically arranged in pairs radially on the inner ring 20, and the bottom wall of the recessed grooves 221 gradually slopes inward from top to bottom. The inner ring 20 is screwed into the outer casing through the external thread 222. The operating gap formed between the recessed grooves 221 and the inner wall of the outer casing allows the user to easily unscrew the inner nozzle for maintenance and cleaning without any tools, simply by inserting their fingers into the operating gap.

[0027] The first spray plate 31 has multiple first spray holes, and the second spray plate 32 has multiple second spray holes. The shapes and numbers of the first and second spray holes are different. When the spray base 30 is in the first spray position, the first spray plate 31 is on top and the second spray plate 32 is on the bottom. The water first flows through the first inlet plate and then sprays out from the second spray holes of the second spray plate 32. When the spray base 30 is rotated 180 degrees from the first spray position to the second spray position, the first spray plate 31 is on the bottom and the second spray plate 32 is on top. The water first flows through the second inlet plate and then sprays out from the first spray holes of the first spray plate 31. The water spray mode can be quickly switched by flipping the water spray base 30. Whether it is in the first water spray position or the second water spray position, the water flow first passes through the upper plate and then sprays out from the lower plate. The upper plate can play the role of rectifying and pre-distributing the water flow, so that the water spray pattern that is finally sprayed from the lower plate is more stable and uniform. In addition, the water spray base 30 has the same central axis as the inner ring 20 and the outer cover when it is in the first water spray position and the second water spray position, so as to reduce the water outlet resistance and ensure smooth water outlet.

[0028] When the spray base 30 is rotated 90 degrees from the first and second spray positions to the cleaning position, the central axis of the spray base 30 is perpendicular to the central axis of the inner ring 20, and there are operating gaps between the first spray plate 31 and the second spray plate 32 and the inner ring wall 21 of the inner ring 20. During routine cleaning, the spray base 30 can be rotated to the cleaning position, creating operating gaps between the first spray plate 31, the second spray plate 32 and the inner ring wall 21. Users can then use cleaning tools to clean the first spray plate 31 and the second spray plate 32, achieving in-situ cleaning without disassembly. This is very suitable for simple daily maintenance cleaning. For deep cleaning, disassembly and cleaning can be performed, making cleaning and maintenance convenient and labor-saving.

[0029] The outer wall 33 of the water spray base 30 and the inner ring wall 21 of the inner ring 20 are both spherical. The inner ring wall 21 supports the outer wall 33. The water spray base 30 is supported on the spherical inner ring wall 21 of the inner ring 20 through the spherical structure, which allows for smooth rotation and good sealing. To facilitate the rotation of the water spray base 30, a first switching rod 311 is vertically provided in the center of the first water spray plate 31, and a second switching rod 321 is vertically provided in the center of the second water spray plate 32. The axial height of the first switching rod 311 and the second switching rod 321 is not greater than the maximum radius of the water spray base 30, so as to avoid the first switching rod 311 and the second switching rod 321 contacting the inner ring wall 21 of the inner ring 20 and forming resistance during the rotation process.

[0030] The axial height of the built-in ring 20 is greater than the axial height of the spray seat 30. When the spray seat 30 is located at the first spray position and the second spray position, both the first spray plate 31 and the second spray plate 32 are recessed into the water outlet cavity. The bottom wall of the built-in ring 20 is flush with the bottom wall of the outer casing. The above configuration makes the overall structure of the shower head compact, with the entire built-in spray head embedded in the outer casing, without any protruding parts, resulting in a simple and beautiful appearance.

[0031] The shower head disclosed in this embodiment can be as follows: Figure 7 As shown, it is assembled on the handheld tube 40 and used as a handheld shower head, or as... Figure 8 As shown, multiple intervals are assembled on the fixed water pipe 50 and used as fixed shower heads.
