Description

Technical Field

[0001] This invention relates to the field of water outlet devices, and more specifically to a water outlet structure and a water outlet device. Background Technology

[0002] Fan-shaped water jets, with their larger impact range and more comfortable spray force, have been widely used in showerheads, smart toilets, and spray nozzles. However, considering the insufficient impact force of fan-shaped water jets under low pressure, most water outlet structures with fan-shaped water jet functionality require an acceleration channel that extends along the water flow direction. This acceleration channel results in a larger thickness of the water outlet component in the water flow direction, making it impossible to meet the requirements for extremely thin designs. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a water outlet structure with a fan-shaped water outlet function and meeting the requirements of ultra-thinness, and a water outlet device having the water outlet structure.

[0024] Option 13, based on Options 9 to 12, wherein the water inlet cavity is annular; and multiple water outlet structures are provided and evenly distributed along the circumference of the water inlet cavity.

[0025] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0026] In the relevant technical solutions and their preferred embodiments, when water flows through the inlet tank, some water flows directly from the tank opening to the water passage hole. Since the first symmetry plane passes through the axis of the water passage hole, meaning the water passage hole is located in the middle of the length direction of the inlet tank, when the inlet tank is full of water, some water also flows from near the water passage hole, i.e., from the outside to the inside, to the water passage hole. Because the length direction of the outlet tank forms an angle with the length direction of the inlet tank, the water flow forms a fan-shaped water pattern after entering the outlet tank from the inlet tank. Each sub-tank extends from the outside to the inside to the first symmetry plane, and the width of each sub-tank at least partially decreases from the outside to the inside. When the water flows from the outside to the inside towards the water passage hole, the water flow is accelerated, increasing the impact force of the water flow. The impact force is stronger under low pressure and helps the fan-shaped water form fine particulate water at the bottom. Since the length direction of each sub-tank is parallel to the acceleration path, the length of the acceleration path of the water flow along each sub-tank from the outside to the inside only affects the length, width, or diameter of the outlet structure, and does not affect the thickness of the outlet structure. Therefore, the water outlet structure can meet the acceleration requirements while also allowing for a smaller thickness. The two sub-channels are symmetrically arranged relative to the first symmetrical surface. As the water flows from the outside to the inside along each sub-channel, the water flows into or out of each other, which helps to form a fan-shaped water flow and increases the impact force of the water outlet.

[0027] In the relevant technical solutions and their preferred embodiments, since the depth of each sub-trough gradually increases at least partially along the direction close to the water passage, the bottom of each sub-trough forms an inclined guiding surface that directs the water flow from the outside to the water passage, thus guiding the water flow. Furthermore, since the bottoms of both sub-troughs are sloped, the overall flow area of ​​the inlet tank gradually decreases from the opening to the bottom, accelerating the water flowing from the opening to the bottom and increasing the impact force of the outflow, which helps the fan-shaped water to form fine particulate water at the bottom.

[0028] In the relevant technical solutions and their preferred embodiments, since the width of each sub-trough is at least partially narrowed along the direction from its opening to its bottom, the water flow from the opening to the bottom can be accelerated, increasing the impact force of the water flow.

[0029] In the relevant technical solutions and their preferred embodiments, since each sub-trough is symmetrically arranged relative to the second symmetrical surface, the sub-trough structure has a uniform shape, which helps to form a fan-shaped water feature and a better water pattern.

[0030] In the relevant technical solutions and their preferred embodiments, the second symmetry plane is perpendicular to the length direction of the water outlet channel, so that the angle between the length direction of each sub-channel and the length direction D1 of the water outlet channel is 90 degrees. When the angle is 90 degrees, the resulting fan-shaped water pattern is better.

[0031] In the relevant technical solutions and their preferred embodiments, since the first and second sections of the water outlet trough form a first notch and a second notch on the first and second walls, and both the first and second notches are located between the opening of the water passage hole on the bottom wall of the water inlet trough and the second end face, the first and second notches are higher than the opening of the water passage hole on the bottom wall of the water inlet trough. Part of the water flow can flow from the first and second notches to the two sides of the water outlet trough located on the water passage hole, so that the water outlet trough can form a fan-shaped water flow, and the fan-shaped water flow pattern is better.

[0032] In the relevant technical solutions and their preferred embodiments, in the prior art, most of the water passage holes are spindle-shaped. However, in this embodiment, since the projections of the water passage holes, the first notch, and the second notch on the projection plane perpendicular to their axes together form a circle and allow water to pass through, compared to the spindle shape, it helps to increase the flow velocity of the water in the middle of the fan-shaped water and increase the impact force of the fan-shaped water. At the same time, when the flow velocity of the water in the middle of the fan-shaped water is faster, an adsorption force is generated, causing the water droplets on the periphery to gather towards the center, thus avoiding an excessively large washing area of ​​the fan-shaped water.

[0033] In the relevant technical solutions and their preferred embodiments, since the projection contour line formed by the water passage hole, the first notch and the second notch is located between or tangent to the projection contour line of the water outlet channel on the projection plane perpendicular to the axis of the water passage hole, it helps to increase the flow rate of the water in the middle of the fan-shaped water, increase the impact force of the fan-shaped water, and help the fan-shaped water form fine particulate water at the bottom.

[0034] In the relevant technical solutions and their preferred embodiments, since the outline formed by the water passage hole, the first notch and the second notch are located between the outer contour lines of the projection of the water inlet trough on the projection plane perpendicular to the axis of the water passage hole, it helps to increase the flow rate of the water in the middle of the fan-shaped water, increase the impact force of the fan-shaped water, and help the fan-shaped water form fine particulate water at the bottom.

[0035] In the relevant technical solutions and their preferred embodiments, the dimensions of the outlet trough gradually widen along the direction away from the inlet trough to ensure the water output and outlet area of ​​the fan-shaped water outlet. On the projection plane perpendicular to the axis of the water passage, the projection of the water passage is elliptical, and a fan-shaped jet can be formed through the elliptical water passage.

[0036] In the relevant technical solutions and their preferred embodiments, since the water outlet device has any of the water outlet structures described above, it has all the beneficial effects of the aforementioned water outlet structures.

[0037] In the relevant technical solutions and their preferred embodiments, the water outlet structure is installed at the mounting hole of the water outlet device, which facilitates replacement.

[0038] In the relevant technical solutions and their preferred embodiments, the water outlet structure is directly formed on the third wall of the water outlet device, which eliminates the need for installation and makes it more convenient.

[0039] In the relevant technical solutions and their preferred embodiments, since the water inlet cavity is annular and each water outlet structure is evenly arranged along the circumference of the water inlet cavity, when water flows through the water inlet cavity, the water spray of the shower head is composed of multiple circumferentially arranged fan-shaped water jets, resulting in a better visual effect and user experience.

[0062] Example 1:

[0063] like Figure 1 As shown, the water outlet device includes a water outlet device body 1 and a water outlet structure 2.

[0064] like Figure 2 As shown, the main body 1 of the water outlet device is provided with a water inlet chamber 11. In this embodiment, the main body 1 of the water outlet device is provided with a plurality of mounting holes 111 communicating with the water inlet chamber 11. Specifically, the bottom wall of the water inlet chamber 11 is provided with mounting holes 111, and the mounting holes 111 are provided with slots (not shown in the figure) penetrating the bottom wall of the water inlet chamber 11 on their hole walls. In this embodiment, the water inlet chamber 11 is rectangular, and the water outlet structure 2 is arranged along the length direction of the water inlet chamber 11. The shape of the water inlet chamber 11 and the arrangement of the water outlet structure 2 are not limited to this embodiment and can be adjusted according to actual needs. For example, in other embodiments, the water inlet chamber 11 can also be set as annular. There are multiple water outlet structures 2, which are evenly distributed along the circumference of the water inlet chamber 11. So that when water flows through the water inlet chamber 11, the water spray of the shower head is composed of multiple circumferentially arranged fan-shaped water, which improves the visual effect and user experience.

[0065] like Figure 2-6 As shown, the water outlet structure 2 is provided with a water outlet groove 213, a water passage hole 214, a water inlet groove 215, a first end face 2111, and a second end face 2121.

[0066] The water outlet trough 213 and the water inlet trough 215 open onto the first end face 2111 and the second end face 2121, respectively, and the water outlet trough 213 is adapted to form a fan-shaped water flow. A water passage hole 214 penetrates the bottom walls of the water outlet trough 213 and the water inlet trough 215 to connect them. In this embodiment, the first end face 2111 and the second end face 2121 are planar and opposite to each other; however, in other embodiments, they can also be curved surfaces, etc.

[0067] like Figure 3 , 4 As shown, the inlet tank 215 is divided into two symmetrically arranged sub-tanks 2151 by a first plane of symmetry A1. The first plane of symmetry A1 passes through the axis L of the water passage and is perpendicular to the length direction of the inlet tank 215. The two sub-tanks 2151 are symmetrically arranged with respect to the first plane of symmetry A1. When the water flows from the outside to the inside along each sub-tank 2151, the water flow can collide or squeeze with each other, which helps to form a fan-shaped water flow and increases the impact force of the water flow. Here, "inside" refers to the direction closer to the water passage 214, and "outside" refers to the direction away from the water passage 214.

[0068] like Figure 4 As shown, each sub-trough 2151 is further divided into a symmetrical first part 21511 and a symmetrical second part 21512 by a second symmetry plane A2; the second symmetry plane A2 is parallel to the length direction of the inlet trough 215. Each sub-trough 2151 is also symmetrically arranged relative to the second symmetry plane A2, and the sub-trough 2151 has a uniform shape and structure, which helps to form a fan-shaped water flow and improves the water pattern. In this embodiment, the second symmetry plane A2 passes through the axis L of the water passage hole and is perpendicular to the first symmetry plane A1.

[0069] Each sub-channel 2151 extends from the outside inward to the first plane of symmetry A1, and the width of each sub-channel 2151 gradually decreases from the outside inward at least partially or entirely. (From the top view of the water outlet structure 2) Figure 4 As you can see, the openings of each sub-slot 2151 are roughly fan-shaped.

[0070] The depth of each sub-slot 2151 gradually increases from the outside in, at least partially or entirely. In this embodiment, such as... Figure 7 As shown, the bottom of each sub-slot 2151 is arc-shaped.

[0071] The width of each sub-slot 2151 gradually decreases at least partially or entirely along the direction from its opening to its bottom. In this embodiment, as... Figure 9 As shown, the sidewalls of the first part 21511 and the second part 21512 of each sub-slot 2151 facing the second symmetry plane A2 are inclined surfaces that gradually approach the second symmetry plane A2 along the direction from the slot opening to the bottom of each sub-slot 2151.

[0072] like Figure 4 As shown, the two side walls of the water inlet tank 215 facing the second symmetry plane A2 are the first wall 2152 and the second wall 2153.

[0073] like Figure 6 As shown, in this embodiment, on the projection plane perpendicular to the axis L of the water passage, the outer contour of the water outlet 213 is approximately spindle-shaped. The structure of the water outlet 213 at section AA is as follows. Figure 7 As shown, it is roughly inverted V-shaped. Figure 6 As shown, the structure of the water outlet trough 213 at section BB is as follows: Figure 8 As shown.

[0074] The outlet trough 213 gradually widens in the direction away from the inlet trough 215; this ensures the water flow rate and area of ​​the fan-shaped outlet. For example... Figure 6 As shown, the length direction of the water outlet trough 213 is parallel to the first end face 2111 and perpendicular to the vertical direction D3. In this embodiment, the length direction of the water outlet trough 213 is perpendicular to the second symmetry plane A2. Since the first symmetry plane A1 is perpendicular to the length direction of the water inlet trough 215, and the first symmetry plane A1 is perpendicular to the second symmetry plane A2, the length direction of the water outlet trough 213 forms a right angle with the length direction of each sub-trough 2151. Experiments have shown that this arrangement results in a better fan-shaped water pattern. It should be understood that, in addition to a right angle, the length direction of the water outlet trough 213 and the length direction of each sub-trough 2151 can also be an obtuse angle or an acute angle, that is, the length direction of the water outlet trough 213 forms an angle with the second symmetry plane A2.

[0075] The water outlet trough 213 is divided into a first trough segment and a second trough segment, which are symmetrically arranged, by the second symmetry plane A2. For example... Figure 10 , 11 As shown, the first and second trough segments penetrate the first wall 2152 and the second wall 2153 respectively, forming a first notch 2131 and a second notch 2132 on the first wall 2152 and the second wall 2153. The first notch 2131 and the second notch 2132 are both located between the opening of the water passage hole 214 on the bottom wall of the water inlet trough 215 and the second end face 2121, and both connect the water inlet trough 215, the water outlet trough 213, and the water passage hole 214.

[0076] In this embodiment, since the structure of the water outlet trough 213 at section AA is inverted V-shaped, the first notch 2131 and the second notch 2132 are approximately inverted V-shaped. Because the first and second sections of the water outlet trough 213 form the first notch 2131 and the second notch 2132 on the first wall 2152 and the second wall 2153, and both the first notch 2131 and the second notch 2132 are located between the opening of the water passage hole 214 on the bottom wall of the water inlet trough 215 and the second end face 2121, the first notch 2131 and the second notch 2132 are higher than the opening of the water passage hole 214 on the bottom wall of the water inlet trough 215. This allows some water to flow from the first and second notches 2132 to both sides of the water outlet trough 213 located on the water passage hole 214, enabling the water outlet trough 213 to form a fan-shaped water flow, and the resulting fan-shaped water flow pattern is better.

[0077] like Figure 6 As shown, the projections of the water passage hole 214, the first notch 2131, and the second notch 2132 onto a projection plane perpendicular to the water passage hole axis L together form a circle. In this embodiment, the water passage hole axis L is parallel to the vertical direction D3. On the projection plane perpendicular to the water passage hole axis L, refer to... Figure 4 The outline formed by the water passage 214, the first notch 2131, and the second notch 2132 is located between the projected outer outline of the water inlet trough 215. This arrangement helps to increase the flow velocity of the water in the middle of the fan-shaped water, increase the impact force of the fan-shaped water, and help the fan-shaped water form fine particles at the bottom.

[0078] On the projection plane perpendicular to the axis L of the water passage hole, the projection contour line formed by the water passage hole 214, the first notch 2131, and the second notch 2132 is located between or tangent to the projection outer contour line of the water outlet trough 213. This helps to increase the flow velocity of the water in the middle of the fan-shaped water, increase the impact force of the fan-shaped water, and help the fan-shaped water form fine particulate water at the bottom. In this embodiment, as... Figure 6 As shown, the projected outline formed by the water passage 214, the first notch 2131, and the second notch 2132 is tangent to the projected outer outline of the water outlet 213.

[0079] like Figure 2 As shown, the water outlet structure 2 is disposed on the body 1 of the water outlet device, and is adapted to and installed on the mounting hole 111. The water inlet chamber 11 is connected to the water inlet tank 215. The water outlet structure 2 is installed at the mounting hole 111 of the water outlet device for easy replacement.

[0080] In this embodiment, as Figure 3 As shown, the specific structure of the water outlet structure 2 includes a water outlet structure body 21 and an insert block 22. The water outlet structure body 21 extends along the vertical direction D3 and is integrally formed by two first columns 211 and second columns 212 with different diameters. The first columns 211 and second columns 212 are arranged from top to bottom along the vertical direction D3, and the diameter of the first column 211 is smaller than the diameter of the second column 212. (Refer to...) Figure 2 The diameter of the second column 212 is larger than that of the mounting hole 111. When installed in place, the second column 212 abuts against the water outlet device body 1, facilitating the installation and positioning of the water outlet structure 2. The insert 22 protrudes from the side wall of the first column 211 and is fitted with the slot on the mounting hole 111 to prevent the water outlet structure 2 from rotating. Of course, the insert 22 can also be set on the water outlet structure 2, and the slot can be set on the water outlet device body 1.

[0081] like Figure 3-5As shown, the end face of the first column 211 facing away from the second column 212 forms a second end face 2121, and the end face of the second column 212 facing away from the first column 211 forms a first end face 2111. The water outlet trough 213, the water passage hole 214, and the water inlet trough 215 are all provided on the water outlet structure body 21.

[0082] like Figure 1-12 As shown, in this embodiment, when the water outlet device is in use: water is introduced into the inlet chamber 11, and the water flows into the inlet tank 215. Some water flows directly from the tank opening to the water passage hole 214. Since the first symmetry plane A1 passes through the water passage hole axis L, that is, the water passage hole 214 is located in the middle of the length direction of the inlet tank 215; when the inlet tank 215 is full of water, some water also flows from the outside to the inside to the water passage hole 214. Some of the water in the inlet tank 215 flows from the first notch 2131 and the second notch 2132 to the outlet tank 213 located on both sides of the water passage hole 214, and some water flows out in a columnar shape from the water passage hole 214, making the outlet tank 213 form a fan-shaped water flow. In the prior art, most of the water passage holes 214 are spindle-shaped. However, in this embodiment, the projections of the water passage holes 214, the first notch 2131, and the second notch 2132 onto the projection plane perpendicular to the axis L of the water passage holes together form a circle. This helps to increase the flow rate of the water in the middle of the fan-shaped water and increase the impact force of the fan-shaped water. At the same time, when the flow rate of the water in the middle of the fan-shaped water is relatively fast, an adsorption force is generated, causing the water droplets on the periphery to gather towards the center, thus avoiding an excessively large washing area of ​​the fan-shaped water.

[0083] like Figure 4 As shown, each sub-channel 2151 extends from the outside to the inside along a direction parallel to the second end face 2121 to the first symmetry plane A1, and the width of each sub-channel 2151 gradually decreases from the outside to the inside. When the water flows from the outside to the inside towards the water passage 214, the water flow is accelerated, increasing the impact force of the water flow. The impact force is stronger under low pressure, and it also helps the fan-shaped water to form fine particles at the bottom. Furthermore, since the length direction of each sub-channel 2151 is parallel to the second end face 2121, the length of the acceleration path of the water flow along each sub-channel 2151 from the outside to the inside only affects the length, width, or diameter of the water outlet structure 2, and does not affect the thickness of the water outlet structure 2. Therefore, the water outlet structure 2 can meet the acceleration requirements, and its thickness can also be set to be smaller.

[0084] like Figure 7 , 9As shown, since the depth of each sub-trough 2151 gradually increases along the direction close to the water passage 214, the bottom of each sub-trough 2151 forms an inclined guiding surface that directs the water flow from the outside to the inside to the water passage 214, thus guiding the water flow. Furthermore, since the bottoms of both sub-troughs 2151 are sloped, the overall flow area of ​​the inlet tank 215 gradually decreases from the opening to the bottom, accelerating the water flowing from the opening to the bottom and increasing the impact force of the outflow, which helps the fan-shaped water to form fine particles at the bottom. Moreover, since the width of each sub-trough 2151 gradually narrows from its opening to its bottom, the water flow from the opening to the bottom is accelerated, increasing the impact force of the outflow.

[0085] In this embodiment, the water inlet 215 can be accelerated whether it flows directly from the inlet to the bottom or from the outside to the inside along the sub-channel 2151, thereby increasing the impact force of the fan-shaped water. Due to the design of the inlet 215 structure in this embodiment, the overall thickness of the outlet structure 2 can be made thinner, meeting the requirements for ultra-thinness.

[0086] In other embodiments, the projection of the water passage 214 on a projection plane perpendicular to the axis L of the water passage is elliptical. A fan-shaped jet can also be formed through the elliptical water passage 214.

[0087] Example 2:

[0088] like Figure 13-14 As shown, the difference between this embodiment and embodiment one is that in this embodiment, the water outlet structure 2 is formed on the third wall 112 of the water outlet device body 1, and the upper and lower surfaces of the third wall 112 respectively form the second end face 2121 and the first end face 2111.

[0089] In this embodiment, as Figure 13-14 As shown, the water inlet cavity 11 is annular. Multiple water outlet structures 2 are provided and evenly distributed along the circumference of the water inlet cavity 11. The bottom wall of the water inlet cavity 11 is a third wall 112. The surface of the third wall 112 facing the water inlet cavity 11 is the upper surface, and the surface facing away from the water inlet cavity 11 is the lower surface. The water inlet groove 215, water outlet groove 213, and water passage hole 214 of each water outlet structure 2 are all located on the third wall 112 and evenly distributed along the circumference of the water inlet cavity 11. Because the water inlet cavity 11 is annular and the water outlet structures 2 are evenly distributed along the circumference of the water inlet cavity 11, when water flows through the water inlet cavity 11, the shower head's spray consists of multiple circumferentially arranged fan-shaped water jets, resulting in a better visual effect and user experience. The shape of the water inlet cavity 11 and the arrangement of the water outlet structures 2 are not limited to the examples in this embodiment and can be adjusted according to actual needs.

[0090] like Figure 13-14As shown, the usage of this embodiment is the same as that of Embodiment 1 above, and it has all the beneficial effects of the water outlet structure 2 in Embodiment 1. In this embodiment, the water outlet structure 2 is directly formed on the third wall 112 of the water outlet device, eliminating the need for installation and making it more convenient.

[0091] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
