Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] This utility model relates to a water nozzle, which includes a body 100 made of elastic material.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the body 100 can be made of elastic materials such as silicone or rubber. The interior of the body 100 is hollow, forming a water-passing cavity 200, which has an inlet end 210 and an outlet end 220. In the direction shown, the water-passing cavity 200 is placed vertically, with the upper end being the inlet end 210 and the lower end being the outlet end 220, and the inlet end 210 and outlet end 220 are positioned opposite each other. Water flows into the water-passing cavity 200 from the inlet end 210, flows vertically downwards, and then sprays out from the outlet end 220. The cross-sectional direction of the water-passing cavity 200 is perpendicular to the water flow direction. In the direction shown, if the water flow direction of the water-passing cavity 200 is vertical, then the cross-sectional direction of the water-passing cavity 200 is horizontal. The cross-sectional profile 230 of the water passage cavity 200 includes an annular edge 231 and a connecting edge 232. The annular edge 231 is open-loop shaped, and the annular edge 231 and the connecting edge 232 are distributed sequentially in a ring-shaped racetrack pattern. Figure 3As shown, two circular edges 231 are arranged opposite each other, one on the left and one on the right, and two connecting edges 232 are arranged opposite each other, one in front and one behind. The connecting edges 232 connect the two circular edges 231, with the left end of the connecting edge 232 connecting to the end of the left circular edge 231 and the right end connecting to the end of the right circular edge 231. The connecting edges 232 are arc-shaped, protruding towards the interior of the water passage cavity 200; that is, the connecting edge 232 on the front protrudes backward in an arc shape, and the connecting edge 232 on the rear protrudes forward in an arc shape. When the water passage cavity 200 is not subjected to external force (no water flow), the cross-sectional profile 230 of the water passage cavity 200 is generally figure-eight shaped, and the connecting edges 232 on both sides do not contact each other. Based on the shape of the cross-sectional profile 230, the inner wall of the water passage cavity 200, corresponding to the position of the connecting edges 232, protrudes towards the center of the water passage cavity 200 in a first arc surface 260. A water nozzle is used on a water outlet device, which can be a shower head, spray gun, etc. After water is supplied to the water outlet device, the water flows from the inlet end 210 into the water passage chamber 200, and then sprays out from the outlet end 220. For example... Figure 4 As shown, water pressure acts on the inner wall of the water passage cavity 200. As the water pressure increases, the main body 100 undergoes elastic deformation and expands outward, increasing the distance between the two connecting edges 232 and the cross-sectional area of ​​the outlet end 220, thereby increasing the water flow. Since the straight-line distance between two points is the shortest, the inwardly protruding first arc surface 260 in the water passage cavity 200, compared to a straight surface, can increase the contact area between the water and the water passage cavity 200. From the basic formula: force = water pressure × contact area, it can be concluded that under the same water pressure, the larger the contact area, the greater the force. When the water pressure flowing through the water passage cavity 200 is greater, the deformation of the outlet end 220 is effectively increased with the cooperation of the first arc surface 260. From the steady flow energy equation: volumetric flow rate = outlet area × outlet velocity, it can be seen that when the flow rate is constant, the outlet velocity is inversely proportional to the outlet area. When the water pressure of the water outlet increases, the force exerted by the water flow on the outlet end 220 also increases synchronously, increasing the cross-sectional area of ​​the outlet end 220. Although the increased pressure also leads to a relatively increased flow rate, the increased cross-sectional area of ​​the outlet end 220 slows down the increase in water velocity, thus reducing the impact of the water flow on the human body and providing a pressure relief function. The water outlet is adaptive to water pressure; the water flow impact is relatively strong at low water pressure and relatively gentle at high water pressure.

[0030] Among them, such as Figure 3As shown, under the condition that the water passage cavity 200 is not subjected to external force, the minimum distance between the two connecting edges 232 is A, and the inner diameter of the annular edge 231 is B, which satisfies A≤B / 3. Under the condition that the water passage cavity 200 is not subjected to external force, the two ends of the connecting edge 232 are tangent to the annular edges 231 on both sides. That is, in the direction shown in the figure, the left end of the connecting edge 232 is tangent to the end of the annular edge 231 located on the left, and this tangency point is defined as the first tangency point 241. The right end of the connecting edge 232 is tangent to the end of the annular edge 231 located on the right, and this tangency point is defined as the second tangency point 242. The straight-line distance between the first tangency point 241 and the second tangency point 242 belonging to the same connecting edge 232 is C, and the maximum straight-line distance between the two annular edges 231 is D, which satisfies C≥D / 3. In this embodiment, the straight line containing the maximum straight-line distance between the two annular edges 231 passes through the center point of the two annular edges 231. Within the aforementioned size ratio range, the area of ​​the first arc surface 260 of the water passage cavity 200 at the position corresponding to the connecting edge 232 can be guaranteed. If the first arc surface 260 is too small, the contact area between the water flow and the first arc surface 260 will be too small, which will weaken the force on the water passage cavity 200, causing the deformation at the water outlet 220 to be too small, thus losing the pressure reduction function.

[0031] One embodiment, such as Figure 2 As shown, the cross-sectional area of ​​the water passage cavity 200 gradually decreases from the inlet end 210 to the outlet end 220. In the direction shown, the cross-sectional area of ​​the water passage cavity 200 gradually decreases from top to bottom. Water flows onto the cavity wall of the water passage cavity 200. Due to the inclined cavity wall and the elastic deformation of the main body 100 under water pressure, the water flow can flush the cavity wall of the water passage cavity 200, achieving a self-cleaning effect. Specifically, the cavity wall of the water passage cavity 200 forms an angle K with the direction of the water flow, satisfying 13° ≥ K ≥ 3°. In this embodiment, the water flow direction of the water passage cavity 200 is vertical, and the cavity wall of the water passage cavity 200 is inclined. Within this angle range, it is possible to avoid the angle being too large or too small, which would affect the deformation capability of the main body 100, thereby ensuring the self-cleaning effect and pressure reduction function.

[0032] In one embodiment, such as Figure 3 and Figure 4As shown, the outer contour surface 110 of the body 100 has a first cut 120 recessed towards the water cavity 200. The recessed direction of the first cut 120 is consistent with the protruding direction of the connecting edge 232. In the illustrated direction, the middle of the front side of the outer contour surface 110 of the body 100 is recessed to form a first cut 120, which is consistent with the protruding direction of the connecting edge 232 located on the front side. The middle of the rear side of the outer contour surface 110 of the body 100 is recessed to the front, consistent with the protruding direction of the connecting edge 232 located on the rear side. The first cut 120 can be arc-shaped or V-shaped. When the water cavity 200 is subjected to water pressure, the water pressure acts on the cavity wall of the first arc surface 260 corresponding to the connecting edge 232, and the body 100 expands outward and undergoes elastic deformation. The first cut 120 can reduce the wall thickness at the corresponding position of the body 100, making it easier for the position of the body 100 corresponding to the first arc surface 260 to deform.

[0033] In one embodiment, such as Figure 5 As shown, the annular edge 231 has an arc edge 250 protruding towards the center of the cross-sectional contour 230. The arc edges 250 on both sides of the annular edge 231 protrude relative to each other. The cavity wall of the water passage cavity 200 at the corresponding position of the arc edge 250 forms a second arc surface 270. The second arc surface 270 further increases the contact area between the cavity wall of the water passage cavity 200 and the water flow, thereby improving the adaptive water pressure effect of the body 100. Furthermore, the outer contour surface 110 of the body 100 has a second cut 130 recessed towards the water passage cavity 200. The recessed direction of the second cut 130 is consistent with the protruding direction of the arc edge 250. The second cut 130 can be set as an arc-shaped or V-shaped recess. In the direction shown in the figure, a second cut 130 is provided on the left side of the left annular edge 231, and the second cut 130 is recessed to the right. A second cut 130 is provided on the right side of the right annular edge 231, and the second cut 130 is recessed to the left. When the water cavity 200 is subjected to water pressure, the water pressure acts on the cavity wall of the second arc surface 270 corresponding to the annular edge 231, and the body 100 expands outward and undergoes elastic deformation. The second cut 130 can reduce the wall thickness at the corresponding position of the body 100, making it easier for the position of the body 100 corresponding to the second arc surface 270 to deform.

[0034] This utility model also relates to a water dispensing device. A water nozzle is used on the water dispensing device. For example... Figure 6 As shown, the water dispensing device includes a base 300. The base 300 can be a silicone disc. Multiple water nozzles are provided on the base 300. The water nozzles can be detachably mounted on the base 300, for example, by snap-fit. Alternatively, the water nozzles can be integrally molded onto the base 300. The water nozzles on the base 300 can be of a uniform size or can be configured with multiple sizes to provide various water dispensing effects.
