Description

Technical Field

[0001] This invention relates to bathroom products, and more particularly to water outlet devices. Background Technology

[0002] Showerheads are common bathroom fixtures. Traditional showerheads typically only have a single spray function with a simple water spray pattern. Existing showerheads have added the ability to spray granular water, as illustrated by Chinese patent application CN201520434216.9, which discloses a granular water showerhead. This showerhead has a water outlet cover with a first water outlet area inside. This first water outlet area contains several concentrically distributed groups of water outlets. Each group of water outlets includes an outer ring water outlet and an inner ring water outlet. The water flow from the outer and inner ring water outlets is oblique to the central axis and in opposite directions. The water flow impacts the rotating rotor, causing the water flow from the inner and outer ring water outlets to interweave and collide, forming granular water. However, the water flow impact force of this granular water showerhead is weakened by the rotor and other components, resulting in a shorter spray distance and a smaller spray range. Furthermore, the small particle size makes it difficult to achieve a massage effect. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a water outlet structure that can form a spiral particle water spray, and the water spray particles are large and have a strong impact force.

[0004] To solve the above-mentioned technical problems, the present invention provides a water outlet structure for particulate water, including: a rotor and a water outlet nozzle; the rotor is used to drive the water outlet nozzle to rotate or swing eccentrically relative to the rotor, the water outlet nozzle has a water outlet channel, and a flow straightener extending along the water outlet direction is provided in the water outlet channel.

[0010] In a preferred embodiment: the rectifier is arranged along the axial direction of the water outlet channel.

[0011] In a preferred embodiment: the water outlet is connected to the rotor via a reversing member, which is used to reverse the rotation of the rotor into the oscillation of the water outlet.

[0012] In a preferred embodiment: the commutator is a commutator block eccentrically connected to the rotor; the commutator block is fixedly connected to the water outlet.

[0013] In a preferred embodiment: the water outlet includes a connecting portion for connecting the rotor, and a water outlet portion extending axially along the water outlet, the water outlet channel is disposed in the water outlet portion, and the sidewall of the water outlet is provided with a water inlet between the connecting portion and the water outlet portion.

[0014] In a preferred embodiment: the rotor has a through hole along the thickness direction for mounting the water outlet; the water outlet is provided with a water outlet channel through the through hole along the axial direction.

[0018] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0019] This invention provides a water outlet structure for producing granular water. A rotor drives the water outlet to rotate eccentrically. The centrifugal force generated during this rotation disperses the water column flowing from the outlet channel into granular particles, forming granular water. Because the outlet is constantly rotating, the granular water is distributed in a spiral pattern. Furthermore, a flow straightener is incorporated into the water outlet channel to improve turbulence, resulting in larger water particles, stronger impact, and lower temperature drop. This significantly enhances the user's showering experience. Attached Figure Description

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0035] Example 1

[0036] refer to Figures 1-6 This embodiment provides a water outlet device, including a water outlet device body 1, a faceplate assembly 2, and a water outlet structure 3 for forming spiral particle water. The faceplate assembly 2 is placed inside the water outlet device body 1 and has a chamber for installing the water outlet structure 3. The water outlet device in this embodiment is a handheld shower head. As a simple replacement, other water outlet devices can also be used, such as faucets, overhead shower heads, etc.

[0037] To form spiral granular water, the aforementioned water outlet structure 3 includes a rotor 31 and a water outlet 32. The rotor 31 drives the water outlet 32 ​​to rotate eccentrically relative to the rotor 31. The water outlet 32 ​​has a water outlet channel, and a flow straightener 33 extending along the water outlet direction is disposed within the water outlet channel. The rotor 31 drives the water outlet 32 ​​to rotate eccentrically, causing the centrifugal force generated during the rotation of the water outlet 32 ​​to break the water column flowing out of the water outlet channel into granular shapes, forming granular water. Since the water outlet 32 ​​is constantly rotating, the granular water forms a spiral granular distribution as it rotates. Furthermore, the flow straightener 33 disposed within the water outlet channel of the water outlet 32 ​​improves turbulence, resulting in larger water droplets, stronger impact, and lower temperature drop, significantly enhancing the user's showering experience.

[0038] In order for the rotor 31 to drive the water outlet 32 ​​to rotate eccentrically, the rotor 31 must first be able to rotate. For this purpose, the 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 set in the flow channel so that it can rotate around its own axis under the drive of the water flow.

[0039] In this embodiment, the rotor 31 is an impeller. The water flow in the flow channel impacts the blades of the impeller from the side, which drives the impeller to rotate.

[0040] Specifically, the faceplate 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 because of the sealing ring 222, the water will not leak out from the gap between the second mounting hole 221 and the water outlet 32.

[0041] 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 the rotor 31 and a water outlet portion 322 extending axially along the water outlet 32. The water outlet channel is disposed in the water outlet portion 322, and the side wall of the water outlet 32 ​​has a water inlet hole 323 between the connecting portion 321 and the water outlet portion 322. The rotor 31 has a insertion hole at an eccentric position for insertion into the connecting portion 321, and the insertion hole is inclined relative to the axial direction of the rotor 31, so that the axis of the water outlet 32 ​​after installation forms an acute angle with the axis of the rotor 31.

[0042] The function of the aforementioned rectifier 33 is to prevent turbulence in the water flow channel, allowing the water to flow orderly along the direction of the rectifier 33's extension, without rotating within the water flow channel. Therefore, the upper end of the rectifier 33 is positioned at the portion connecting the water outlet 322 and the water inlet 323, ensuring that the water flowing into the water outlet 322 is rectified immediately. The end of the rectifier 33 is spaced a certain distance from the end of the water flow channel because the water flow in the water flow channel has already formed an orderly flow after being rectified by the rectifier 33. This eliminates the need for the rectifier 33 to be too long; it only needs to cover a portion of the water flow channel. In this embodiment, the rectifier 32 is positioned along the axial direction of the water flow channel.

[0043] The aforementioned rectifier 33 can be integrally formed with the water outlet 32, or they can be two separate parts, with the rectifier 33 installed inside the water outlet 32 ​​through a connecting structure.

[0044] Finally, through Figure 7 and Figure 8A particle size analysis comparison can be performed between 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, mainly concentrated between 105μm and 850μm. In contrast, the particle size distribution of spiral granular water is between 284μm and 2080μm, mainly concentrated between 468μm and 2080μm. Notably, the proportion of particles larger than 1145μm reaches 58.78%, meaning that nearly 60% of the effluent particles exceed the maximum particle size of conventional granular water. Therefore, the structure in this embodiment has a very significant effect on increasing the size of the effluent particles.

[0045] Example 2

[0046] refer to Figure 9 and Figure 10 The difference between this embodiment and Embodiment 1 is that in Embodiment 1, only the water outlet 32 ​​has water flowing through its outlet portion, while in Embodiment 2, the water outlet 32 ​​has a water flow channel extending axially throughout, meaning the entire water outlet 32 ​​has water flowing through it. Water flows from the rotor into the water flow channel. Therefore, the rotor 31 has a through hole 311 along its thickness direction for mounting the water outlet, allowing the water flow channel to pass through the through hole.

[0047] Example 3

[0048] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the water outlet 32 ​​rotates eccentrically relative to the rotor 31, thus producing spiral particulate water. In this embodiment, the water outlet 32 ​​oscillates relative to the rotor 31, eliminating the spiral effect in Embodiment 1, but it does not affect the particle size distribution of the particulate water and still has the effect of increasing the size of the outlet particles.

[0049] refer to Figure 11 and 12 In this embodiment, the water outlet 32 ​​is connected to the rotor 31 via a reversing block 34. The reversing block 34 is used to convert the rotation of the rotor 31 into the oscillation of the water outlet 32. Specifically, the reversing block 34 is eccentrically connected to the rotor 31; the reversing block 34 is fixedly connected to the water outlet 32. Thus, as the rotor 31 rotates, the reversing block 34 oscillates accordingly, thereby causing the water outlet 32 ​​to oscillate as well.

[0050] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
