Detailed Implementation

[0034] 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.

[0035] This utility model relates to a throttling mechanism, including a water-saving body 100 and a water-blocking ring 200.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the water-saving main body 100 is provided with a water-passing area 110 and a water-blocking part 120. The water-blocking part 120 is located in the middle of the water-saving main body 100. The water-blocking part 120 can be configured as a disc, and the water-passing area 110 is arranged around the water-blocking part 120. The number of water-passing areas 110 can be two, three or more, with at least two water-passing areas 110 distributed around the water-blocking part 120. In this embodiment, the water-saving main body 100 is provided with three water-passing areas 110, which are arranged sequentially around the water-blocking part 120, with adjacent water-passing areas 110 spaced apart. Figure 3 As shown, the axial direction of the water-saving body 100 is vertical, and the radial direction is horizontal. The water-passing area 110 extends vertically through the water-saving body 100 along its axial direction. The water-blocking ring 200 is preferably circular, but can also be a square ring or other annular shape. The water-blocking ring 200 is elastic and can undergo elastic deformation under external force. The water-blocking ring 200 is installed on the lower side of the water-saving body 100. A portion of the water-blocking ring 200 is positioned opposite the water-passing area 110, and the water-passing area below the water-passing area 110 is controlled according to the magnitude of the elastic deformation of the water-blocking ring 200. Some portions of the water-blocking ring 200 are located below the interval between two adjacent water-passing areas 110.

[0037] In practical use, the throttling mechanism can be installed on water outlet devices such as shower heads, faucets, and overhead showers. After water is supplied to the outlet device, the water-blocking part 120 is located on the upstream side, and the water-blocking ring 200 is located on the downstream side. Water impacts the throttling mechanism from the side away from the water-blocking ring 200. When the water flow impacts the water-saving body 100, a portion of the water flow directly impacts the upper side of the water-blocking part 120 and the upper side of the interval between two adjacent water passages 110, thereby generating a large impact force on the water-saving body 100 and achieving a flow-blocking effect. A portion of the water flows directly through the water passage 110 and impacts the water-retaining ring 200. The portion of the water-retaining ring 200 opposite the water passage 110 forms a high-pressure zone 201. Other portions of the water-retaining ring 200, due to the water-retaining effect at the intervals between adjacent water passages 110, form low-pressure zones 202. This creates a circumferential pressure distribution along the water-retaining ring 200, with high-pressure zones 201, low-pressure zones 202, and so on. Because of the alternating high and low pressure distribution on the water-retaining ring 200, the low-pressure zone 202 remains largely undeformed when the inlet water pressure increases. The low-pressure zone 202 effectively limits the deformation of the high-pressure zone 201, thus effectively controlling the deformation of the water-retaining ring 200 within a relatively small range. This prevents the water-retaining ring 200 from becoming excessively large or small due to changes in inlet water pressure. The water-blocking ring 200 tends to have a relatively stable deformation trend under different water pressures. The obstruction range of the water flow area of ​​the water flow zone 110 will not be too large or too small. Ultimately, the water flow rate of the water outlet device can be kept stable within a small range under different water pressures, and the water flow shape can be well maintained.

[0038] In one embodiment, the upper side of the water-blocking part 120 is provided with a plurality of grooves 130. One end of the groove 130 extends through to the water-passing area 110. The number of grooves 130 is determined according to the number of water-passing areas 110, and the grooves 130 are paired with the water-passing areas 110 one by one. The grooves 130 can be configured as straight grooves, etc., and the grooves 130 radially extend through to the water-passing area 110 along one end of the water-blocking part 120. In this embodiment, each groove 130 extends radially from the center of the water-blocking part 120 to each water-passing area 110. The ends of each groove 130 near the center of the water-blocking part 120 are interconnected, or they can be configured to be spaced apart from each other. For example, the water-saving body 100 is provided with three water-passing areas 110, and the water-blocking part 120 is provided with three grooves 130, each groove 130 extending in the direction of the three water-passing areas 110 respectively, with one groove 130 extending to one water-passing area 110. Furthermore, the water-blocking portion 120 is provided with a pressure-controlling area 140, which penetrates the water-saving body 100 vertically along its axial direction. The pressure-controlling area 140 and the groove 130 are connected radially to each other in the water-blocking portion 120. Alternatively, the pressure-controlling area 140 can be directly formed in the groove 130, or it can be a through-hole extending through the water-saving body 100 in the groove 130. In this embodiment, it can also be as follows: Figure 4As shown, the pressure control zone 140 is located at one end of the groove 130 away from the center of the water-blocking part 120. The water-blocking part 120 is cylindrical. The area enclosed by the dotted line of the spatial circle containing the circumferential sidewall of the water-blocking part 120 and one end of the groove 130, forming a semicircle, is the pressure control zone 140. The pressure control zone 140 and the corresponding water passage zone 110 are interconnected radially along the water-saving body 100. The cross-section of the pressure control zone 140 in the radial direction of the water-saving body can also be circular, arc-shaped, fan-shaped, polygonal, or elliptical, among other shapes. After water is supplied to the water outlet device, the water blocked by the water-blocking part 120 is dispersed into the groove 130, the water passage zone 110, and the pressure control zone 140. A portion of the water flow impacts the groove 130, which also obstructs the flow of water along the axial direction of the water-saving body 100. The water enters each groove 130 for rectification and flows to the corresponding water passage zone 110. When pressure control zone 140 is provided, water rectified by groove 130 falls directly into pressure control zone 141. The groove 130 reduces the amount of water directly impacting the upper side of water baffle 120, thus reducing the backflow and turbulence caused by impacting the upper side of water baffle 120. A portion of the water directly impacts pressure control zone 140. After entering pressure control zone 140, the water flows directly downward along the axial direction of water-saving body 100. Because pressure control zone 140 is offset from water baffle ring 200, only a very small amount of water impacts water baffle ring 200 or does not impact water baffle ring 200 when flowing along pressure control zone 140. After passing through pressure control zone 140, the water continues to flow towards the spray side of the water outlet device. Water baffle ring 200 is offset from each pressure control zone 140, that is, water baffle ring 200 avoids each pressure control zone 140 and does not block the lower part of pressure control zone 140. like Figure 6 As shown, when the pressure control zone 140 is located at the end of the groove 130 away from the center of the water-blocking part 120, water impact at the part of the water-blocking ring 200 that is radially opposite to the pressure control zone 140 can directly flow into the pressure control zone 140 for pressure relief, thus forming a low-pressure zone 202 at the position of the water-blocking ring 200 opposite to the pressure control zone 140. The part of the water-blocking ring 200 located below the water passage 110 but not aligned with the pressure control zone 140 is a high-pressure zone, resulting in a pressure distribution state of high-pressure zone 201, low-pressure zone 202, and high-pressure zone 201 at the part of the water-blocking ring 200 located below the water passage 110, making the part of the water-blocking ring 200 located below the water passage 110 tend to have a more stable deformation trend.

[0039] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the water-saving main body 100 also includes a support portion 150. The support portion 150 is arranged around the water-blocking portion 120, and the support portion 150 can be configured as a ring or other shapes. A water-passing area 110 is formed between the support portion 150 and the water-blocking portion 120, and a connecting portion 160 is provided between the support portion 150 and the water-blocking portion 120. Adjacent water-passing areas 110 are separated by the connecting portion 160. A portion of the water-blocking ring 200 is located below the connecting portion 160, and the portion of the water-blocking ring 200 that aligns with the connecting portion 160 forms the aforementioned low-pressure area 202. By setting the size of the connecting portion 160, the distribution of the high-pressure area 201 and the low-pressure area 202 on the water-blocking ring 200 is controlled. During installation, the support portion 150 is installed in the water outlet device as the support portion 150 of the water-saving main body 100. When water enters, a portion of the water flow impacts the support portion 150 and the connecting portion 160, causing flow obstruction. The surfaces of the support portion 150, the connecting portion 160, and the water-blocking portion 120 that are away from the water-blocking ring 200 are flush. That is, the upper surfaces of the support portion 150, the connecting portion 160, and the water-blocking portion 120 are on the same plane, ensuring uniform flow obstruction when water impacts these components.

[0040] Furthermore, such as Figure 5 and Figure 8 As shown, the water-blocking portion 120 extends axially from the side away from the groove 130 into an extension portion 180. A water-blocking ring 200 is disposed around the extension portion 180. A pressure-controlling zone 140 extends axially downward through the extension portion 180. After water flows from the water passage 110 and impacts the water-blocking ring 200, the water flows towards the pressure-controlling zone 140. By extending the axial length of the pressure-controlling zone 140 using the extension portion 180, the water-blocking ring 200 and the extension portion 180 cooperate to guide the water flowing into the pressure-controlling zone 140 axially downward, thereby reducing turbulence after the water flows through the throttling mechanism.

[0041] Based on the above embodiments, such as Figure 4 As shown, the connecting portion 160 connects the circumferential sidewall of the water-retaining portion 120 and the supporting portion 150. Alternatively, as... Figure 7 As shown, the connecting part 160 is connected between the side wall of the pressure control zone 140 and the support part 150. When the water flows through the end of the groove 130, it will be diverted to the water passage zones 110 on both sides under the action of the connecting part 160 and impact the water baffle ring 200 at the corresponding position.

[0042] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the system also includes a housing 300, the interior of which is hollow to form a water cavity 310. The water cavity 310 has an inlet 311 and an outlet 312 at its upper and lower ends, respectively. The water cavity 310 contains a first step portion 320 and a second step portion 330. The cross-sectional shapes of the first step portion 320 and the second step portion 330 are determined according to the outer contour shapes of the water-saving body 100 and the water-blocking ring 200, respectively. If the outer contour of the water-saving body 100 is circular, then the cross-section of the step portion is defined as circular. If the water-blocking ring 200 is circular, then the cross-section of the second step portion 330 is also circular. The maximum inner diameter of the first step portion 320 is greater than the maximum inner diameter of the second step portion 330. The water-saving body 100 is mounted on the first step portion 320, which supports the water-saving body 100. The minimum inner diameter of the first step portion 320 is less than or equal to the minimum inner diameter of the water-blocking ring 200, preventing water from directly impacting the first step portion 320. The second step 330 is arranged around the outlet 312. A water-blocking ring 200 is installed on the second step 330, and the water passage 110 is opposite to the outlet 312. Water enters from the inlet 311, flows through the water passage 110, and is discharged from the outlet 312. The outer casing 300 can be cylindrical or other shapes, and the throttling mechanism is installed through the outer casing 300 in conjunction with the internal pipe of the water outlet device.

[0043] Furthermore, a protruding edge 170 extends from the circumferential sidewall of the support portion 150 of the water-saving body 100. A groove 321 is provided on the circumferential inner wall of the first step portion 320, and the protruding edge 170 is engaged in the groove 321, thereby fixing the water-saving body 100 in the outer shell 300. The water-saving body 100 and the second step portion 330 cooperate to restrict the water-blocking ring 200 in the water cavity 310.
