Description

Technical Field

[0001] The utility model relates to a shower head. Background Art

[0002] At present, the common shower heads that can switch the water outlet mode adopt the following principle: at least two types of water outlet holes are provided on the water outlet disc. By rotating the water distribution disc, the water path is changed, and water flows out from different types of water outlet holes on the water outlet disc, which is water of different modes.

[0003] The disadvantages of the shower head adopting this principle are obvious. That is, the number of water outlet holes that can be set on the water outlet disc is limited. Suppose there are originally thirty water outlet holes of type A on the water outlet disc, and now a type B water outlet hole is to be added. This will inevitably lead to a reduction in the number of type A water outlet holes, affecting the corresponding shower experience. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a shower head that can discharge water in two modes. The water of the two modes shares the water outlet holes of the shower head, and there is a relatively good shower experience in both modes.

[0005] To solve the above problems, the utility model provides a shower head, including a body and a water outlet component. The body has a water inlet, a body water outlet hole, and a water inlet channel connecting the water inlet and the body water outlet hole. The water inlet is used to connect with a water pipe that supplies water to the shower head. The water outlet component is rotatably installed on the body with its upper side facing the body, and the water outlet component can rotate and switch between a first position and a second position relative to the body. A first water inlet hole and a second water inlet hole are provided on the upper side of the water outlet component. A plurality of shower water outlet holes are provided on the lower side of the water outlet component, and the upper part of the shower water outlet holes gradually narrows along the water outlet direction. A water distribution disc is provided in the middle of the water outlet component. The water distribution disc divides the internal space of the water outlet component into an upper chamber and a lower chamber. A plurality of first water passing holes and a second water passing hole are provided on the water distribution disc. The first water passing holes correspond to the shower water outlet holes one by one, and the second water passing hole is arranged to align with the second water inlet hole. The hole wall of the second water inlet hole extends downward to the water distribution disc. A water collecting partition is provided around each shower water outlet hole in the lower chamber. Each water collecting partition encloses a sub-chamber in the lower chamber, and the sub-chamber communicates with the corresponding first water passing hole and the shower water outlet hole. When the water outlet component is in the first position, the first water inlet hole is communicated with the body water outlet hole, and water flows through the first water inlet hole, the first water passing hole, the sub-chamber, and the shower water outlet hole in sequence. Each water collecting partition has at least one water inlet gap, and the water inlet direction of the water inlet gap is eccentrically arranged relative to the shower water outlet hole. When the water outlet component is in the second position, the second water inlet hole is communicated with the body water outlet hole, and water flows through the second water inlet hole, the second water passing hole, the water inlet gap, the sub-chamber, and the shower water outlet hole in sequence.

[0006] When using the shower head provided by the present utility model, water flows out from the same shower head water outlet holes in two water outlet modes, and the shower area remains unchanged, enabling users to have a better shower experience compared to the aforementioned existing shower heads.

[0024] The utility model provides a new shower structure, which is suitable for handheld showers and overhead showers. Figures 1a to 1j as well as Figures 2a to 2d One embodiment of the present invention is described below, which is a handheld shower head.

[0025] In this embodiment, the shower head includes a water outlet assembly 1 and a body 2. The water outlet assembly 1 can be rotatably mounted on the body 2, with the upper side facing the body 2 and a plurality of shower outlet holes 14 provided on the lower side. The upper portion of the shower outlet holes 14 gradually narrows along the water outlet direction, while the lower portion of the shower outlet holes 14 has a constant aperture along the water outlet direction. The water outlet assembly 1 is fixed along the direction of the rotation axis I by a stepped shaft 3. The water outlet assembly 1 has a paddle 11. The user pinches the paddle 11 to rotate the water outlet assembly 1 relative to the body 2 to switch the water outlet mode. The switching operation method is the same as that of the aforementioned existing shower heads, which is convenient for users. The body 2 includes a disc portion 21 and a handle portion 22. Figure 1a When the water outlet assembly 1 is in the first position, the paddle 11 of the water outlet assembly 1 is aligned with the handle 22 of the body 2; see Figure 2a When the water outlet assembly 1 is located at the second position, the paddle 11 of the water outlet assembly 1 is staggered with the handle 22 of the body 2 .

[0026] See also Figure 1i and 2a The body 2 has a water inlet 23, a body water outlet 24 and a water inlet channel 25 connecting the water inlet 23 and the body water outlet 24. The water inlet 23 is provided at the free end of the handle 22 and is used to connect to the water pipe supplying water to the shower head. The body water outlet 24 is used to supply water to the water outlet assembly 1. Figure 1c The top side of the water outlet assembly 1 is provided with a first water inlet hole 12 and a second water inlet hole 13, corresponding to the first and second water outlet modes, respectively. The showerhead outlet hole 14 delivers water in different forms. When the water outlet assembly 1 is in the first position, the first water inlet hole 12 communicates with the main body water outlet hole 24, corresponding to the first water outlet mode. When the water outlet assembly 1 is in the second position, the second water inlet hole 13 communicates with the main body water outlet hole 24, corresponding to the second water outlet mode.

[0027] To prevent the water flowing from the water outlet hole 24 of the main body to the water outlet component 1 from leaking between the main body 2 and the water outlet component 1, an elastic gasket 4 is provided between the main body 2 and the water outlet component 1. The elastic gasket 4 is squeezed by the main body 2 and the water outlet component 1 to achieve the sealing function. Refer to Figure 1b and 1i , a through hole 41 corresponding to the water outlet hole 24 of the main body is provided on the elastic gasket 4, so that water can flow from the water outlet hole 24 of the main body into the water outlet component 1.

[0028] Refer to Figure 1i , to reduce the inlet noise of the shower head, a water baffle 27 perpendicular to the inlet direction is provided in the water inlet channel 25 of the main body 2. Multiple water baffles 27 are arranged staggeredly, which can significantly reduce the inlet noise.

[0029] To facilitate the user to rotate the water outlet component 1 to the accurate position and at the same time prevent the water outlet component 1 from accidentally rotating without the user applying a rotational force to a certain extent. Refer to Figure 1b , a positioning component 26 is provided on the lower side of the main body 2. Refer to Figure 1c and 1f , positioning blocks and positioning slots are provided on the upper side of the water outlet component 1 corresponding to the first position and the second position. Refer to Figure 1j , the positioning component 26 includes a convex column 261 on the lower side of the main body 2. The lower side of the convex column 261 is recessed upward to form an installation groove. A compression spring 262 and a top block 263 are sequentially provided in the installation groove from top to bottom. When the water outlet component 1 rotates to the first position, the side surface of the convex column 261 abuts against the positioning block 15A, and the top block 263 is clamped into the positioning slot 16A downward under the action of the spring 262. When the water outlet component 1 rotates to the second position, the side surface of the convex column 261 abuts against the positioning block 15B, and the top block 263 is clamped into the positioning slot 16B downward under the action of the spring 262.

[0030] In this embodiment, the principle of the shower head switching the water outlet mode is:

[0031] Refer to Figures 1d to 1h, the water outlet assembly 1 is composed of a water outlet tray 101, a water distribution tray 102, and a water sealing tray 103 arranged successively from bottom to top. The water distribution tray 102 is welded and fixed to the water outlet tray 101 to form a lower chamber LC; the water sealing tray 103 is welded and fixed to the water distribution tray 102 to form an upper chamber UC. The shower water outlet holes 14 are provided on the water outlet tray 101, the first water inlet hole 12 and the second water inlet hole 13 are provided on the water sealing tray 103, and the water distribution tray 102 is provided with a plurality of first water passing holes M1 and one second water passing hole M2. The first water passing holes M1 correspond to the shower water outlet holes 14 one by one, and the second water passing hole M2 is aligned with the second water inlet hole 13. The hole wall of the second water inlet hole 13 extends downward to the water distribution tray 102 and is welded and fixed, so that the water flowing into the second water inlet hole 13 can directly pass through the upper chamber UC and flow into the lower chamber LC through the second water passing hole M2, while preventing the water flowing into the upper chamber UC from the first water inlet hole 12 from flowing into the second water passing hole M2. A water collecting partition W is provided around each shower water outlet hole 14 on the water outlet tray 101. The upper side of the water collecting partition W is welded and fixed to the water distribution tray 102. The water collecting partition W encloses a sub-chamber SC in the lower chamber LC. The water collecting partition W has a water inlet gap W1.

[0032] See Figure 1h , the water collecting partition W includes an arc-shaped portion surrounding the shower water outlet hole 14 and a U-shaped portion connected to the arc-shaped portion. The opening of the U-shaped portion is communicated with the opening of the arc-shaped portion. The center of the arc of the arc-shaped portion is located on the extension line of the midline of the U-shaped portion. The water inlet gap W1 is provided on the arc-shaped portion. The arc radian of the arc-shaped portion is greater than π, and the inner diameter of the arc-shaped portion is equal to the diameter of the inlet of the shower water outlet hole 14.

[0033] See Figure 3a in 3a-1 and Figure 3b , when the water outlet assembly 1 is in the first position, the first water inlet hole 12 is communicated with the body water outlet hole 24. The water flowing out of the body water outlet hole 24 flows into the upper chamber UC from the first water inlet hole 12, flows into the first part SC1 of the plurality of sub-chambers SC from the upper chamber UC through the plurality of first water passing holes M1, flows from the first part SC1 of the sub-chamber SC to the second part SC2 of the sub-chamber SC, and flows into the shower water outlet hole 14 along the radial direction of the shower water outlet hole 14 from the second part SC2 of the sub-chamber SC, so that the water flowing out of the shower water outlet hole 14 is in the first mode (shower water).

[0034] See Figures 2a to 2f , Figure 3a in 3a-2, Figure 3bWhen the water outlet assembly 1 is in the second position, the second water inlet 13 is connected to the main body water outlet 24. Water flowing out of the main body water outlet 24 passes directly through the upper chamber UC from the second water inlet 13 and flows into the lower chamber LC through the second water flow hole M1. The water in the lower chamber LC flows into the second part SC2 of the sub-chamber SC through the water inlet notch W1. From the second part SC2 of the sub-chamber SC, it flows into the showerhead water outlet 14 along the chord direction of the showerhead water outlet 14, forming a vortex in the showerhead water outlet 14, so that the water flowing out of the showerhead water outlet 14 is the second mode (granular water). "Chordal direction" refers to the direction of the line connecting two points on the arc, which is not the diameter of the circle. Figure 2e and 2f After water flows in from the water inlet gap W1, it hits the arc surface and spirals downward to the outlet of the showerhead water outlet 14. The water is thrown out from the outlet of the showerhead water outlet 14 to form conical distributed particles of water.

[0035] See also Figure 3a and 3b The water inlet opening W1 is perpendicular to the direction of water flow from the first portion SC1 to the second portion SC2, forming a 90° angle. The lower sides of the water inlet opening W1 and the lower sides of the first portion SC1 are coplanar with the upper side (inlet) of the showerhead outlet 14, resulting in a simple structure.

[0036] To ensure uniform water flow from the showerhead, multiple showerhead outlet holes 14 are evenly distributed on the outlet tray 101, rotationally symmetrical about the rotation axis I of the outlet assembly 1. To strengthen the connection between the water sealing tray 103 and the water distribution tray 102, two rings of reinforcing ribs F are installed on the underside of the water sealing tray 103, surrounding the rotation axis I of the outlet assembly 1. The reinforcing ribs F are welded to the water distribution tray 102. To evenly distribute water within the upper chamber UC to the multiple first water flow holes M1, the reinforcing ribs F are evenly distributed with water flow notches F1. The water flow notches F1 are staggered with the first water flow holes M1, allowing water to flow smoothly to the first water flow holes M1 near the edge of the water distribution tray 102.

[0037] See also Figure 1h In order to evenly distribute the water in the lower chamber LC to the multiple sub-chambers SC, the multiple water-collecting partitions W are rotationally symmetrical about the rotation axis I of the water outlet assembly 1, avoiding the situation where the water inlet gaps W1 are concentratedly distributed, resulting in a large flow rate in some shower outlet holes 14 and a small flow rate in other shower outlet holes 14.

[0038] In other embodiments of the present invention, the structure of the shower head may differ from that of the above embodiments in one or more aspects. For example, the water collecting partition may be of other shapes, so that the water flowing into the sub-chamber from the first water through hole falls directly into the shower head outlet hole, instead of first falling next to the shower head outlet hole; for example, the water outlet tray, the water distribution tray and the water sealing tray may be fixed with fasteners instead of welding.
