Description

Technical Field

[0001] The utility model relates to bathroom supplies, in particular to a water outlet device. Background Art

[0002] Showers are common bathroom fixtures. Traditional showerheads typically have only a single spray function, with a relatively simple water pattern. Existing showerheads, based on these traditional showerheads, have added the ability to spray granular water. For example, Chinese patent application number CN201520434216.9 discloses a granular water showerhead. This showerhead features a water outlet cover with a first outlet area located inside. This first outlet area contains several concentrically arranged groups of water outlet holes. Each group includes an outer ring of holes and an inner ring of holes. The water outlets from the outer and inner rings are skewed relative to the central axis and in opposite directions. As the water impacts the rotor, the water flows from the inner and outer rings intertwine and collide, forming granular water. However, the impact of the water flow from this granular water showerhead is weakened by the rotor and other components, resulting in a short spray distance and a narrow range. Furthermore, the small particle size of this showerhead makes it difficult to achieve a massage effect. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1

[0034] refer to Figures 1-6 This embodiment provides a water outlet device, comprising a water outlet device body 1, a cover assembly 2, and a water outlet structure 3 for forming spiral granular water. The cover assembly 2 is placed within the water outlet device body 1 and has a chamber for mounting the water outlet structure 3. The water outlet device in this embodiment is a handheld showerhead. As a simple replacement, other water outlet devices, such as faucets, overhead showerheads, etc., may also be used.

[0035] In order to form spiral granular water, the above-mentioned water outlet structure 3 includes: a rotor 31 and a water outlet 32; the rotor 31 is used to drive the water outlet 32 ​​to rotate eccentrically relative to the rotor 31, and the water outlet 32 ​​has a water outlet channel, and the water outlet 32 ​​is provided with a rectifier 33 extending along the water outlet direction in the water outlet channel. The rotor 31 drives the water outlet 32 ​​to rotate eccentrically, so that the centrifugal force generated by the water outlet 32 ​​during the rotation process throws the water column flowing out of the water outlet channel into particles, forming granular water, and because the water outlet 32 ​​is always in a rotating state, the granular water forms a spiral granular distribution as the water outlet 32 ​​rotates. In addition, a rectifier 33 is provided in the water outlet channel of the water outlet 32, which can improve turbulence, make the water particles larger, have stronger impact, and have a lower temperature drop. It greatly enhances the user's shower experience.

[0036] In order for the rotor 31 to drive the water outlet 32 ​​to rotate eccentrically, the rotor 31 must first be able to rotate. To this end, the surface cover assembly 2 has a water inlet 21 and a flow channel connecting the water inlet 21 and the water outlet channel; the rotor 31 is arranged in the flow channel to rotate around its own axis under the drive of the water flow.

[0037] In this embodiment, the rotor 31 is an impeller, and the water flow in the flow channel hits the blades of the impeller from the side, thereby driving the impeller to rotate.

[0038] Specifically, the face cover assembly 2 includes a front cover 22 and a back cover 23 arranged along the thickness direction of the water outlet device body 1; the back cover 23 has a first mounting hole 231 corresponding to the rotor 31; the front cover 22 has a second mounting hole 221 corresponding to the water outlet 32, and a sealing ring 222 is provided between the side wall of the water outlet 32 ​​and the inner wall of the second mounting hole 221 so that the water outlet 32 ​​can swing in the second mounting hole 221, and since the sealing ring 222 is provided, water will not leak from the gap between the second mounting hole 221 and the water outlet 32.

[0039] To achieve eccentric rotation of the rotor 31 with the water outlet 32 ​​relative to the rotor 31, the water outlet 32 ​​includes a connecting portion 321 for connecting to the rotor 31 and a water outlet portion 322 extending axially along the water outlet 32. The water outlet flow channel is provided in the water outlet portion 322. The sidewall of the water outlet 32 ​​is provided with a water inlet hole 323 between the connecting portion 321 and the water outlet portion 322. The rotor 31 is provided with a socket at an eccentric position for plugging into the connecting portion 321. The socket is tilted relative to the axial direction of the rotor 31, so that the axis of the installed water outlet 32 ​​forms an acute angle with the axis of the rotor 31.

[0040] The function of the above-mentioned rectifier 33 is to prevent the water flow from forming turbulent flow in the water outlet channel, so that the water flow can flow in an orderly manner along the direction in which the rectifier 33 extends, and will not rotate in the water outlet channel. Therefore, the upper end of the rectifier 33 is set at the part where the water outlet part 322 is connected to the water inlet 323, so that the water flow that has just entered the water outlet part 322 can be rectified. The end of the rectifier 33 is separated from the end of the water outlet channel by a certain distance. This is because the water flow in the water outlet channel has formed an orderly water flow after being rectified by the rectifier 33. In this way, there is no need to make the rectifier 33 too long, and it only needs to cover part of the water outlet channel. In this embodiment, the rectifier 32 is set along the axial direction of the water outlet channel.

[0041] The above-mentioned rectifying piece 33 can be integrally formed with the water outlet 32, or can be two separate parts from the water outlet 32, and then the rectifying piece 33 is installed in the water outlet 32 ​​through a connecting structure.

[0042] Finally, by comparing the particle size analysis of conventional granular water and the spiral granular water in this embodiment, it can be seen that the particle size distribution of conventional granular water is between 43μm and 1145μm, and is mainly concentrated in the range of 105μm to 850μm. The particle size distribution of the spiral granular water is between 284μm and 2080μm, and is mainly concentrated in the range of 468μm to 2080μm. In particular, the particle size above 1145μm accounts for 58.78%, which means that nearly 60% of the water outlet particle size exceeds the particle size of the largest particle of conventional granular water. Therefore, the structure in this embodiment has a very obvious effect on increasing the size of the water outlet particle size.

[0043] Example 2

[0044] refer to Figure 7 and Figure 8 This embodiment differs from Example 1 in that, whereas the water outlet nozzle 32 in Example 1 only passes water through the outlet portion, the water outlet channel in Example 2 extends axially through the water outlet nozzle 32, meaning that water passes through the entire water outlet nozzle 32. Water flows from the rotor into the outlet channel. To this end, the rotor 31 has a through hole 311 along its thickness for mounting the water outlet nozzle, allowing the outlet channel to pass through the through hole.

[0045] Example 3

[0046] This embodiment differs from Example 1 in that, in Example 1, the water outlet 32 ​​rotates eccentrically relative to the rotor 31, thereby producing spiral granular water. In this embodiment, the water outlet 32 ​​swings relative to the rotor 31, eliminating the spiral effect of Example 1. However, this does not affect the particle size distribution of the granular water, and still increases the size of the discharged water particles.

[0047] refer to Figure 9 and 10 In this embodiment, the water spout 32 is connected to the rotor 31 via a reversing block 34. This reversing block 34 is used to convert the rotation of the rotor 31 into the swinging of the water spout 32. Specifically, the reversing block 34 is eccentrically connected to the rotor 31 and fixedly connected to the water spout 32. As the rotor 31 rotates, the reversing block 34 swings accordingly, which in turn drives the water spout 32 to swing accordingly.

[0048] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
