Detailed Description of the Embodiments

[0034] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where 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 by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] The present invention relates to a throttling mechanism, which includes a water-saving main body 100 and a water-blocking ring 200.

[0036] As Figure 1 , Figure 2 , Figure 3 and Figure 4 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 at the middle position of the water-saving main body 100. The water-blocking part 120 can be set in a disc shape, and a 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, and at least two water passing areas 110 are distributed around the water-blocking part 120. In this embodiment, three water passing areas 110 are provided on the water-saving main body 100, and the three water passing areas 110 are sequentially distributed around the water-blocking part 120, and adjacent water passing areas 110 are arranged at intervals. In Figure 3 the shown direction, the axial direction of the water-saving main body 100 is the vertical direction, and the radial direction is the horizontal direction. The water passing area 110 penetrates the water-saving main body 100 vertically along the axial direction of the water-saving main body 100. The water-blocking ring 200 is preferably set in a circular shape, and can also be set in other ring shapes such as a square ring. The water-blocking ring 200 has elasticity and can undergo elastic deformation under the action of an external force. The water-blocking ring 200 is installed on the lower side of the water-saving main body 100. A part of the water-blocking ring 200 is opposite to the position of the water passing area 110, and the water passing area below the water passing area 110 is controlled according to the size of the elastic deformation of the water-blocking ring 200. Some parts of the water-blocking ring 200 are located below the interval between two adjacent water passing areas 110.

[0037] In actual use, the throttling mechanism can be installed on water outlet devices such as showers, faucets, and rain shower heads for use. After the water outlet device is filled with water, 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 far away from the water blocking ring 200. When the water flow impacts the water-saving main body 100, a part of the water flow directly impacts the upper side of the water blocking part 120 and the upper side at the interval between two adjacent water passing areas 110, thereby generating a relatively large impact force on the water-saving main body 100 and having a water blocking effect on the water. A part of the water directly impacts the water blocking ring 200 through the water passing area 110. A high-pressure area 201 is formed at the position of the water blocking ring 200 opposite to the water passing area 110. Other parts of the water blocking ring 200 form a low-pressure area 202 due to the water blocking effect at the interval between adjacent water passing areas 110. The water blocking ring 200 forms a pressure cycle distribution of high-pressure area 201, low-pressure area 202, high-pressure area 201, low-pressure area 202... along the circumferential direction. Since the water blocking ring 200 has a distribution of large and small pressures, when the inlet water pressure increases, the low-pressure area 202 basically does not deform, and the low-pressure area 202 has a certain restrictive effect on the deformation of the high-pressure area 201, thereby effectively controlling the deformation of the water blocking ring 200 within a small range, so that the whole water blocking ring 200 will not become too large or too small due to the increase or decrease of the inlet water pressure. The water blocking ring 200 tends to have a relatively stable deformation trend under different water pressures, and the blocking range of the water passing area 110 will not be too large or too small. Finally, the water outlet flow rate of the water outlet device can be stabilized within a small change range under different water pressures, and the water outlet shape can be well maintained.

[0038] In one embodiment, a plurality of grooves 130 are provided on the upper side surface of the water blocking portion 120. One end of the groove 130 extends through to the water passing area 110. The number of the grooves 130 is determined according to the number of the water passing areas 110 provided, and the grooves 130 are paired with the water passing areas 110 one by one. The groove 130 can be set in a straight groove shape or the like, and the groove 130 radially penetrates and communicates with the water passing area 110 along one end of the water blocking portion 120. In this embodiment, each groove 130 extends radially from the center of the water blocking portion 120 to each water passing area 110. The ends of each groove 130 near the center of the water blocking portion 120 are communicated with each other, or can be set to have intervals therebetween. For example, three water passing areas 110 are provided on the water saving main body 100, and three grooves 130 are provided on the water blocking portion 120. Each groove 130 extends in the direction of the three water passing areas 110 respectively, and one groove 130 correspondingly extends to one water passing area 110. Further, a pressure control area 140 is provided on the water blocking portion 120, and the pressure control area 140 axially penetrates the water saving main body 100 up and down along the water saving main body 100. The pressure control area 140 is communicated with the groove 130 in the radial direction of the water blocking portion 120. It can be that the pressure control area 140 is directly opened in the groove 130, and the pressure control area 140 can directly penetrate the water saving main body 100 in the groove 130 in the shape of a through hole. In this embodiment, it can also be, such as Figure 4As shown, the pressure control area 140 is provided at one end of the groove 130 away from the center of the water retaining part 120, and the water retaining part 120 is cylindrical. The area enclosed by the dotted line of the space circle where the circumferential side wall of the water retaining part 120 and one end of the groove 130 is the pressure control area 140. The pressure control area 140 and the corresponding water passing area 110 are interconnected along the radial direction of the water-saving body 100. Among them, the cross-section of the pressure control area 140 in the radial direction of the water-saving body can also be circular, arc-shaped, fan-shaped, polygonal or elliptical arc-shaped or other shapes. After the water outlet device passes water, the water blocked by the water retaining part 120 will be dispersed into the groove 130, the water passing area 110 and the pressure control area 140. A part of the water flow impacts the groove 130, and the groove 130 also has a flow blocking effect on the 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 passing area 110. When the pressure control area 140 is provided, the water rectified by the groove 130 falls directly into the pressure control area 141. The provision of the groove 130 can reduce the amount of water directly impacting the upper side of the water retaining portion 120, that is, reduce the phenomenon of water flow turbulence caused by splashing due to impacting the upper side of the water retaining portion 120. A portion of the water directly impacts the pressure control area 140. After entering the pressure control area 140, the water flows directly downward along the axial direction of the water-saving body 100. Since the pressure control area 140 is staggered with the water retaining ring 200, when the water flows along the pressure control area 140, only a small amount of water impacts the water retaining ring 200 or does not impact the water retaining ring 200. After passing through the pressure control area 140, the water continues to flow to the water spraying side of the water outlet device. The water retaining ring 200 is staggered with each pressure control area 140, that is, the water retaining ring 200 avoids each pressure control area 140, and the water retaining ring 200 does not block the bottom of the pressure control area 140. like Figure 6 As shown, when the pressure control area 140 is opened at one end of the groove 130 away from the center of the water retaining part 120, water impact can directly flow into the pressure control area 140 for pressure relief at the position of the water retaining ring 200 opposite to the pressure control area 140 in the radial direction, so that the position of the water retaining ring 200 opposite to the pressure control area 140 forms a low pressure area 202. The part of the water retaining ring 200 located below the water passing area 110 but not aligned with the pressure control area 140 is a high pressure area, so that the part of the water retaining ring 200 located below the water passing area 110 forms a pressure distribution state of high pressure area 201, low pressure area 202, and high pressure area 201, so that the part of the water retaining ring 200 located below the water passing area 110 tends to have a more stable deformation trend.

[0039] In some specific embodiments of the present invention, Figure 1 , Figure 2 and Figure 3As shown, the water-saving main body 100 further includes a support portion 150. The support portion 150 is disposed around the water-blocking portion 120, and the support portion 150 can be set to a circular ring shape or other shapes. The 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 spaced apart by the connecting portion 160. A partial portion of the water-blocking ring 200 is located below the connecting portion 160, and the portion of the water-blocking ring 200 opposite to the connecting portion 160 forms the above-mentioned 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 as the support portion 150 of the water-saving main body 100 into the water outlet device. When water enters, a part of the water flow is blocked when it impacts on the support portion 150 and the connecting portion 160. Among them, the surface of the support portion 150 away from the water-blocking ring 200, the surface of the connecting portion 160 away from the water-blocking ring 200, and the surface of the water-blocking portion 120 away from the water-blocking ring 200 are flush. That is, the upper side surfaces of the support portion 150, the connecting portion 160, and the water-blocking portion 120 are on the same plane, ensuring uniform water flow blocking when the water flow impacts on the support portion 150, the connecting portion 160, and the water-blocking portion 120.

[0040] Further, as Figure 5 and Figure 8 shown, on the side of the water-blocking portion 120 away from the groove 130, an extension portion 180 extends axially. The water-blocking ring 200 is disposed around the extension portion 180. The pressure control area 140 axially penetrates downward through the extension portion 180. After the water flow impacts on the water-blocking ring 200 from the water-passing area 110, the water flow will flow towards the pressure control area 140. By using the extension portion 180 to extend the axial length of the pressure control area 140, the water-blocking ring 200 and the extension portion 180 cooperate to axially guide the water flowing into the pressure control area 140 downward, thereby reducing the phenomenon of turbulent flow of the water flow after passing through the throttling mechanism.

[0041] Based on the above embodiments, as Figure 4 shown, the connecting portion 160 is connected between the circumferential side wall of the water-blocking portion 120 and the support portion 150. Or, as Figure 7 shown, the connecting portion 160 is connected between the side wall of the pressure control area 140 and the support portion 150. In this structure, when the water flow passes through the end of the groove 130, it will be diverted to the water-passing areas 110 on both sides under the action of the connecting portion 160 and impact on the water-blocking rings 200 at the corresponding positions.

[0042] In some embodiments of the present invention, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown in the figure, it further includes a housing 300, and the interior of the housing 300 is hollow to form a water chamber 310. An inlet 311 and an outlet 312 are respectively arranged at the upper and lower ends of the water chamber 310. A first stepped portion 320 and a second stepped portion 330 are provided in the water chamber 310. The cross-sectional shapes of the first stepped portion 320 and the second stepped portion 330 are respectively determined according to the outer contour shapes of the water-saving main body 100 and the water-blocking ring 200. If the outer contour of the water-saving main body 100 is set to be circular, then the cross-section of the stepped portion is defined as circular. If the water-blocking ring 200 is set to be circular, then the cross-section of the second stepped portion 330 is set to be circular. The maximum inner diameter of the first stepped portion 320 is greater than the maximum inner diameter of the second stepped portion 330. The water-saving main body 100 is installed on the first stepped portion 320, and the water-saving main body 100 is supported by the first stepped portion 320. The minimum inner diameter of the first stepped portion 320 is less than or equal to the minimum inner diameter of the water-blocking ring 200 to prevent water from directly hitting the first stepped portion 320. The second stepped portion 330 is arranged around the outlet 312. The water-blocking ring 200 is installed on the second stepped portion 330, and the water passing area 110 is opposite to the position of the outlet 312. Water enters from the inlet 311, flows through the water passing area 110, and then is discharged from the outlet 312. The housing 300 can be set to be cylindrical or other shapes, and the throttling mechanism is installed in cooperation with the internal pipeline of the water outlet device through the housing 300.

[0043] Further, a convex edge 170 extends from the circumferential side wall of the supporting portion 150 of the water-saving main body 100. A clamping groove 321 is provided on the circumferential inner wall of the first stepped portion 320, and the convex edge 170 is clamped in the clamping groove 321, thereby fixing the water-saving main body 100 in the housing 300, and restricting the water-blocking ring 200 in the water chamber 310 through the cooperation of the water-saving main body 100 and the second stepped portion 330.
