DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The utility model relates to a waterfall-type water outlet structure, which comprises a water inlet area 100, a channel area 200 and a mixing area 300.

[0032] like Figure 1 and Figure 3 As shown, the waterfall-type water outlet structure is placed in a space, and the space has a first direction, a second direction and a third direction. The first direction, the second direction and the third direction intersect with each other in pairs, and the angle of intersection may be an acute angle, a right angle or an obtuse angle, etc. In the present embodiment, preferably, the first direction, the second direction and the third direction are perpendicular to each other in pairs. In the direction shown in the figure, the first direction is the up and down direction, the second direction is the left and right direction, and the third direction is the front and back direction. The waterfall-type water outlet structure is applied to the water outlet device, and the water outlet device may be a shower, a faucet, etc. The water outlet device may be assembled from a plurality of components, and the water inlet area 100, the channel area 200 and the mixing area 300 are arranged on each component of the water outlet device. In the present embodiment, it may be, but is not limited to, such as Figure 1 , Figure 2 and Figure 3 As shown, the water outlet device includes a water inlet seat 410, a flow channel carrier plate 420 and a cover plate 430. The water inlet area 100 is arranged in the water inlet seat 410, the channel area 200 is arranged in the flow channel carrier plate 420, the water inlet seat 410 is connected to the flow channel carrier plate 420, the cover plate 430 is connected to the flow channel carrier plate 420 and a mixing area 300 is defined between the two. The water inlet area 100 is a rectangular parallelepiped cavity structure that opens forward in the water inlet seat 410. The water inlet area 100 is provided with a water inlet 101, and the water inlet direction of the water inlet 101 is in a first direction. The water inlet 101 can supply water to the water inlet area 100 from top to bottom or from bottom to top. A plurality of channel areas 200 are distributed in sequence from left to right along the second direction on the flow channel carrier plate 420. The flow channel carrier plate 420 is installed on the front side of the water inlet seat 410, and the water inlet area 100 and the mixing area 300 are distributed in the third direction, and each channel area 200 is connected to the water inlet area 100. Among them, the channel area 200 includes a rectifying channel 210, a transition channel 220 and a diffusion channel 230. The transition channel 220 is used to connect the rectifying channel 210 with the diffusion channel 230. One end of the rectifying channel 210 is connected to the water inlet area 100, and one end of the diffusion channel 230 is connected to the mixing area 300. The rectifying channel 210 and the diffusion channel 230 both extend in the third direction, that is, in the figure, the rectifying channel 210 and the diffusion channel 230 both extend in the front-to-back direction, and the diffusion channel 230 is located at the front side of the rectifying channel 210. The transition channel 220 extends in a curved tube shape, and the transition channel 220 gradually bends and changes direction from the third direction to the first direction. The axial direction of the rear end of the transition channel 220 is in the third direction, and the rear end of the transition channel 220 is connected to the rectifying channel 210. The axial direction of the front end of the transition channel 220 is in the first direction, and the front end of the transition channel 220 is connected to the diffusion channel 230. The diffusion channel 230 is in a flared shape, and one end of the diffusion channel 230 is a small mouth end, and the other end is a large mouth end. The small mouth end of the diffusion channel 230 is connected to the transition channel 220, and the large mouth end is connected to the mixing zone 300, that is, the diffusion channel 230 gradually expands from the small mouth end to the large mouth end in the third direction.

[0033] In actual use, such as Figure 3 and Figure 5As shown, the water inlet 101 can be connected to an external water supply system through a water pipe, and the water supply system can be a water heater, a tap water pipe, etc. Water enters the water inlet area 100 from the water inlet 101 along the first direction, and the water flow impacts the inner wall of the water inlet area 100 opposite to the water inlet 101, so that the water flow is decelerated in the first direction and dispersed in the second direction and the third direction to fill the water inlet area 100. The water flow changes direction in the third direction in the water inlet area 100 and is diverted to each rectifying channel 210. The water in each channel area 200 flows along the rectifying channel 210, the transition channel 220 and the diffusion channel 230 in sequence, and the water enters the transition channel 220 from the rectifying channel 210 in the third direction, and then the water flow flows along the transition channel 220, gradually changes direction from the third direction to the first direction, and finally flows along the first direction to enter the small mouth end of the diffusion channel 230. When the water flows into the diffusion channel 230, it will impact the inner wall of the diffusion channel 230 opposite to the transition channel 220, and then the water changes direction from the small mouth end of the diffusion channel 230 to the third direction, and the water diffuses along the diffusion channel 230. The water enters the mixing zone 300 in a fan-shaped manner along the expanded shape of the large mouth end of each diffusion channel 230. The water entering the mixing zone 300 from two adjacent diffusion channels 230 will intersect, so that the water at the intersection will influence and merge with each other to tend to flow along the third direction, so that the water covers the mixing zone 300, and then the water is discharged from the outlet side of the mixing zone 300 in a waterfall-like manner for users. The water flows from the water inlet area 100 into the rectifying channel 210 for the first change of direction, and the water volume is distributed through each rectifying channel 210. When the water flows through the transition channel 220, it changes direction for the second time to prevent the water from directly rushing into the diffusion channel 230 from the rectification channel 210 along the third direction. The water is filled in the diffusion channel 230 through the transition channel 220 and diffused evenly, which effectively improves the water distribution. The waterfall-like water flow finally discharged is uniform, stable and continuous.

[0034] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, one end of the rectifying channel 210 is connected to the water inlet area 100, and this end of the rectifying channel 210 is the water inlet end 211. The water inlet end 211 can be opened on the side wall of the flow channel carrier plate 420 facing the water inlet area 100. The surface connection of the water flow section of the water inlet end 211 is the surface connection of the opening of the water inlet end 211 on the flow channel carrier plate 420. The water flow section of the water inlet 101 is the cross section perpendicular to the first direction. Among them, the sum of the water flow sections of each water inlet end 211 is not greater than the area of ​​the water flow section of the water inlet 101. With the change of direction of the water inlet 101 and the water inlet end 211, water can enter the water inlet area 100 from the water inlet 101 and fill the water inlet area 100, and then distribute water to each water inlet end 211, which is conducive to the water flow of each rectifying channel 210 being balanced.

[0035] Among them, Figure 3 , Figure 4 and Figure 5 As shown, the radial cross section of the rectifying channel 210 is a cylindrical structure in the shape of a circle. The axial direction of the rectifying channel 210 is the third direction, and its radial cross section is the cross section of the rectifying channel 210 in the plane parallel to the first direction and the second direction. The circular shape of the radial cross section of the rectifying channel 210 can be a semicircle, preferably a circular shape smaller than a semicircle. Correspondingly, the opening shape of the water inlet end 211 is also the radial cross-sectional shape of the rectifying channel 210, that is, the radial cross sections of the rectifying channel 210 at various positions are consistent. In addition, the ratio of the axial length of the rectifying channel 210 to the radius of the radial cross section is equal to or greater than 3, and the ratio can be 3, 3.2, 3.5, 3.8, 4, 4.5, etc. Under this ratio range, when water flows through the rectifying channel 210, the water flow speed and direction can be better adjusted.

[0036] Further, such as Figure 3 As shown, the distance between the connection of the transition channel 220 and the diffusion channel 230 and the end of the rectifying channel 210 away from the water inlet area 100 is D. Equivalently, the length of the transition channel 220 in the third direction is D. The radius of the radial cross section of the rectifying channel 210 is R, which satisfies In this ratio range, water can obtain better diffusion uniformity after flowing through the transition channel 220 .

[0037] In some embodiments of the present invention, the connection between the transition channel 220 and the diffusion channel 230 is located at the bottom of the small mouth end of the diffusion channel 230. The height dimension H1 of the diffusion channel 230 in the first direction is smaller than the height dimension H2 of the rectification channel 210 in the first direction. The bottom surface of the diffusion channel 230 is higher than the bottom surface of the rectification channel 210. It can be that the top surface of the diffusion channel 230 is flush with the top surface of the rectification channel 210. The diffusion channel 230 is flatter in the first direction than the rectification channel 210. While water enters the diffusion channel 230 from the transition channel 220 to diffuse, it can remain full in the first direction, that is, in the height direction of the diffusion channel 230, thereby ensuring that the water flow stably enters the mixing zone 300.

[0038] The water inlet direction of the water inlet 101 and the water outlet direction of the transition channel 220 are opposite in the first direction. Figure 3 As shown, the water inlet 101 has a vertically downward direction, and water can quickly enter the water inlet area 100. The water outlet direction of the transition channel 220 is the direction in which water enters the diffusion channel 230 from the transition channel 220, which is vertically upward. After entering the transition channel 220, the water spreads upward, and after entering the diffusion channel 230, it turns to the third direction and flows forward.

[0039] In some specific embodiments of the present invention, Figure 5 As shown, the diffusion channel 230 is fan-shaped. The fan angle of the diffusion channel 230 is not greater than 60°, and can be 60°, 59°, 55°, 50°, etc. Adjacent diffusion channels 230 share a side wall, which is V-shaped, and the tip of the V is in the direction away from the small mouth end of the diffusion channel 230. Water is dispersed in a fan shape along the side wall of the diffusion channel 230, and the water sprayed from adjacent diffusion channels 230 converges at the V-shaped tip of the shared side wall, so that the water forms a coherent water film in the mixing zone 300. This fan angle is suitable for small-angle diffusion at a lower flow rate to prevent excessive water flow from accumulating on the fan-shaped wall to form an obvious water column.

[0040] Among them, Figure 3 As shown, it also includes a guide area 500. The guide area 500 extends along the water outlet side of the mixing area 300. The guide area 500 is an extension of the water outlet side of the mixing area 300. The water flow is ejected according to the direction of the guide area 500, forming a waterfall-like water outlet.
