Description

Technical Field

[0001] This application relates to the field of water outlet devices, and particularly to a flow rate regulating structure and a water outlet device. Background Art

[0002] The water outlet device includes a main body and a water supply pipe. Water is introduced from a water source into the main body through the pipe. The main body includes a water inlet, a water passing cavity, and a water outlet. The water inlet is connected to the water supply pipe so that water flows from the water supply pipe into the water passing cavity. The water passing cavity is used for water passing, guiding the water flow to the water outlet, and finally the water flows out from the water outlet. In the prior art, in order to control the water flow rate at the water outlet, a valve rod and a driving structure are also provided in the main body, and one end of the valve rod close to the water outlet is divided into a front conical section and a rear conical section. The valve rod slides in the water outlet cavity, and a conical section is provided in the water passing cavity. When the valve rod does not move, no water flows out of the water outlet of the water outlet device, and the water flow is restricted in the water passing cavity behind the rear conical section. When the valve rod moves away from the water outlet direction, water flows out of the water outlet. During the slow movement of the valve rod, the gap between the front conical section of the valve rod and the conical section of the water passing cavity becomes smaller and smaller, and the flow rate also becomes smaller and smaller. The driving structure includes a pull rod, a handle, and a slider. The top of the handle is hinged to the main body. A chute is opened on the upper part of the handle. One end of the pull rod is connected to the chute, and the other end of the pull rod is connected to the rear side end of the flower rod. The middle position of the handle is connected to the slider, and the rear side surface of the slider is slidably connected to the outer wall of the water supply pipe at the water inlet. When using this technical solution, it is found that when using this solution to control the water flow velocity, the water flow rate cannot be adjusted step by step. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned defects or problems in the background art, and provide a flow rate regulating structure and a water outlet device, which are beneficial to the step-by-step regulation of water during water flow regulation.

[0004] To achieve the above purpose, the following technical solutions are adopted:

[0005] The first technical solution relates to a flow rate regulating structure, including: a main body, which is sequentially provided with a first water passing cavity and a second water passing cavity along the water passing direction, and the first water passing cavity is communicated with the second water passing cavity through a water passing hole; and a valve rod, which slides relative to the main body along the water passing direction or away from the water passing direction. It includes a rod body. The first end of the rod body is located in the second water passing cavity, and the second end of the rod body extends into the first water passing cavity along the water passing direction. The rod body is provided with a first water passing part, and the first water passing part is in clearance fit with the water passing hole. The first water passing part is provided with at least two water passing segments along the water passing direction. Each water passing segment is provided with a water passing groove suitable for communicating the first water passing cavity and the second water passing cavity. The water passing groove opens at the outer edge of the rod body. Along the water passing direction, the communicating area of the water passing grooves of each water passing segment increases step by step.

[0006] The second technical solution is based on the first technical solution. Among them, the rod body is further provided with a second water passing part, and the second water passing part is arranged at an interval from the inner wall of the water passing hole.

[0007] The third technical solution is based on the second technical solution. Among them, the valve rod further includes a blocking part fixedly connected to the rod body, and the blocking part is farther away from the second end than each of the first water passing part and the second water passing part.

[0008] The fourth technical solution is based on the third technical solution. Among them, the number of water passing grooves on the water passing section closer to the second end is greater than the number of water passing grooves on the water passing section closer to the first end.

[0009] The fifth technical solution relates to a water outlet device, including an operating member and a flow rate regulating structure as described in any one of the first to fourth technical solutions. The operating member extends out of the body and is connected to the valve rod to drive the valve rod to slide away from the water passing direction.

[0010] The sixth technical solution is based on the fifth technical solution. Among them, the operating member is rotatably connected to the body.

[0011] The seventh technical solution is based on the fifth or sixth technical solution. Among them, the flow rate regulating structure further includes an elastic member, and the elastic member is arranged between the valve rod and the body to drive the valve rod to slide relative to the body along the water passing direction.

[0012] The eighth technical solution is based on the seventh technical solution. Among them, the body is provided with a water inlet and a water outlet, and the water flow is adapted to flow out from the water inlet through the first water passing cavity and the second water passing cavity in sequence to the water outlet.

[0013] Compared with the prior art, the above solutions have the following beneficial effects:

[0014] In the first technical solution, the first water passing cavity is communicated with the second water passing cavity through the water passing hole, and the water passing hole is in clearance fit with the first water passing part. Due to the clearance fit between the water passing hole and the first water passing part, when there is no water passing groove provided on the first water passing part, the water flow is blocked from passing through the water passing hole.

[0015] In the first technical solution, the first water passing part is provided with at least two water passing sections along the water passing direction, and each water passing section is provided with a water passing groove adapted to communicate the first water passing cavity and the second water passing cavity. The setting of the water passing groove is used to guide the water flow to flow from the first water passing cavity to the second water passing cavity through the water passing groove. The water passing groove can communicate the first water passing cavity and the second water passing cavity. When the valve rod slides at the water passing hole, only when the water passing groove communicates the first water passing cavity and the second water passing cavity, the water flow can flow from the first water passing cavity through the water passing groove into the second water passing cavity, which is beneficial to adjusting whether water flows out by the position of the valve rod at the water passing hole.

[0016] In the first technical solution, along the water flow direction, the water flow area formed by the water troughs that can connect the first water chamber and the second water chamber on each water flow section increases step by step. The larger the water flow area, the greater the amount of water that can flow out. The water troughs are arranged on the outer edge of the rod body. Since the water holes and the rod body are in clearance fit, if the water troughs do not connect the first chamber and the second chamber, the water flow cannot flow into the second chamber through the water troughs. The number of water troughs on each water flow section is fixed, and the water flow area on each water flow section is also fixed. When the valve rod slides in the water hole, the water troughs on the water flow section at the water hole determine the water flow area. Along the water flow direction, the gradually increasing communication area of the water troughs on each water flow section is beneficial to the hierarchical regulation of the water volume.

[0017] In the second technical solution, the second water passage part is arranged at an interval from the inner wall of the water hole, so that as long as the second water passage part connects the first water chamber and the second water chamber, the water flow can flow out from the interval between the second water passage part and the inner wall of the water hole. At this time, it is when the water surface is the largest and the water flow rate is the largest.

[0018] In the third technical solution, the blocking part is farther from the second end than each of the first water passage parts and the second water passage parts. When the blocking part abuts against the water hole, it is beneficial to prevent the water flow from flowing out from the gap between the main body and the operating part.

[0019] In the fourth technical solution, the number of water troughs on the water flow section closer to the second end is greater than the number of water troughs on the water flow section closer to the first end, so that the water flow area on the water flow section closer to the second end is always greater than the water flow area on the water flow section closer to the first end. When the valve rod moves in the direction away from the water flow direction, the water flow rate can increase step by step, which is beneficial to regulating the water flow rate.

[0020] In the fifth technical solution, the operating part drives the valve rod to move, making it more convenient to control the movement of the valve rod.

[0021] In the sixth technical solution, the operating part is rotatably connected to the main body, and the valve rod slides in the main body due to the rotation of the operating part.

[0022] In the seventh technical solution, the elastic part is placed between the valve rod and the main body, so that the valve rod can slide along the water flow direction. When there is no need to discharge water, due to the elastic part restoring its deformation, the blocking part on the valve rod is driven to approach and abut against the water hole, thereby controlling the closing of the water flow.

[0045] Embodiment

[0046] Figure 1 and Figure 2 shows the structure of the water outlet device 1 in this embodiment. As Figure 2 shown, the water outlet device 1 includes a flow rate adjustment structure 2, an operating member 3, a threaded joint 4, a water outlet sleeve 5 and a face mask 6. The flow rate adjustment structure 2 is used to adjust the flow rate of the water outlet device 1 in different grades. The flow rate adjustment structure 2 includes a body 7, a valve stem 8 and an elastic member 9. The valve stem 8 is slidably assembled in the body 7. In this embodiment, when the valve stem 8 slides along the water flow direction, the water flow rate gradually decreases until the water outlet device 1 stops discharging water. When the valve stem 8 slides away from the water flow direction, the water flow rate gradually increases until the water outlet device 1 reaches the maximum water flow rate. The elastic member 9 is disposed between the valve stem 8 and the body 7 to drive the valve stem 8 to slide relative to the body 7 along the water flow direction.

[0047] The operating member 3 is rotatably connected to the body 7 and the operating member 3 is rotatably connected to the valve stem 8. As Figure 2As shown, the connection point where the operating member 3 is rotatably connected to the body 7 is separated from the connection point where the operating member 3 is rotatably connected to the valve stem 8. In this embodiment, the connection point where the operating member 3 is rotatably connected to the body 7 is in the negative direction of the Z-axis compared to the connection point where the operating member 3 is rotatably connected to the valve stem 8. When rotating in the ω direction, the connection point where the operating member 3 is rotatably connected to the valve stem 8 rotates in the ω direction with the connection point where the operating member 3 is rotatably connected to the body 7 as the center, and at this time, the valve stem 8 slides away from the water flow direction. In this embodiment, one end of the valve stem 8 extends into the operating member 3 and is rotatably connected to the operating member 3. A rounded surface is provided at the position where the operating member 3 abuts against the body 7, and the operating member 3 is rotatably connected to the body through the rounded surface. Moreover, since the valve stem 8 extends into the operating member 3, the operating member 3 cannot be separated from the valve stem 8.

[0048] As Figure 2 shown, the threaded joint 4 is fixedly connected to the body 7, and the threaded joint 4 is used to connect to a water source so that water can flow into the body 7. The water outlet sleeve 5 is used to disperse the water flow. A plurality of convex small water outlet holes are provided on the water outlet sleeve 5. The convex water outlet holes can restrict the water flow, can have an effect of increasing the water pressure, increase the water outlet pressure, make the water flow speed higher, and enable the water flow of the water outlet device 1 to spray out a farther distance. The mask 6 is used to fix the water outlet sleeve 5 to prevent the water outlet sleeve 5 from moving. The mask 6 is threadedly connected to the body 7, so that the water outlet sleeve 5 is placed between the body 7 and the mask 6 and fixes its position on the body 7.

[0049] Figure 3 shows the structure of the water outlet device 1 in this embodiment. As Figure 2 and Figure 3 shown, the body 7 includes a water inlet 10, a waterproof gasket 27, a water passing member 11, a first sealing ring 12, and a water outlet 13. The body 7 is fixedly connected to the threaded joint 4 at the water inlet 10. A waterproof gasket 27 is provided at the gap fit between the body 7 and the water passing hole 14. The water passing member 11 is assembled inside the body 7 and abuts and cooperates with the body 7. The water passing member 11 includes a water passing hole 14 and a limiting hole 15, and the projections of the axes of the water passing hole 14 and the limiting hole 15 coincide in the X-axis direction. The first sealing ring 12 abuts against the mask 6 and the water passing member 11. As Figure 2 shown, the body 7 is successively divided into a first water passing cavity 16 and a second water passing cavity 17 along the water flow direction, and the first water passing cavity 16 communicates with the second water passing cavity 17 through the water passing hole 14. The water outlet 13 of the body 7 is threadedly connected to the mask 6, and the water outlet sleeve 5 is between the mask 6 and the water passing member 11 and abuts against the mask 6 and the water passing member 11. In this embodiment, the water passing member 11 abuts against the body 7 through the limiting step provided on the body 7, the water outlet sleeve 5 abuts against the water passing member 11, and finally is fixedly connected by screwing the mask 6 to the body 7.

[0050] As Figure 2 and Figure 3As shown, the valve stem 8 includes a rod body 18 and a plugging portion 19. The valve stem 8 slides relative to the body 7 in the water flow direction or away from the water flow direction. The rod body 18 always slides on the water passage hole 14 and the limiting hole 15 of the water passage member 11. The rod body 18 is provided with a first water passage portion 20, a second water passage portion 21, a first end 22 and a second end 23. The first water passage portion 20 cannot extend into the limiting hole 15 and only slides on the water passage hole 14, and the first water passage portion 20 is in clearance fit with the water passage hole 14. The diameter of the second water passage portion 21 is smaller than that of the first water passage portion 20. In this embodiment, the central axes of the first water passage portion 20 and the second water passage portion 21 coincide. The first end 22 of the rod body 18 is located in the second water passage cavity 17, and its second end 23 extends into the first water passage cavity 16 along the water flow direction. As Figure 4 As shown, in this embodiment, the first water passage portion 20 is provided with two water passage segments 24, and the water passage segments 24 are provided with water passage grooves 25 adapted to communicate the first water passage cavity 16 and the second water passage cavity 17. The water passage grooves 25 open to the outer edge of the rod body 18, and along the water flow direction, the communication area of the water passage grooves 25 of each water passage segment 24 increases step by step. In this embodiment, the number of water passage grooves 25 on the water passage segment 24 closer to the second end 23 of the rod body 18 is greater than the number of water passage grooves 25 on the water passage segment 24 closer to the first end 22 of the rod body 18. As Figure 3 and Figure 4 As shown, the water passage segment 24 along the positive X-axis direction is provided with 4 water passage grooves 25, and the water passage segment 24 along the negative X-axis direction is provided with 2 water passage grooves 25. In this embodiment, two of the water passage grooves 25 on the water passage segment 24 along the positive X-axis direction are communicated with the water passage grooves 25 on the water passage segment 24 along the right side of the X-axis. The plugging portion 19 is fixedly connected to the rod body 18, and the plugging portion 19 is farther from the second end 23 of the rod body 18 than each of the first water passage portion 20 and the second water passage portion 21. The plugging portion 19 includes a second sealing ring 26. The second sealing ring 26 is located at the inner wall of the body 7 and abuts against the rod body 18. The second sealing ring 26 is used to prevent the water flowing into the second water passage cavity 17 from flowing out through the gap at the interface between the body 7 and the operating member 3. In this embodiment, the waterproof gasket 27 is closer to the second end 23 relative to the water passage groove 25, and the waterproof gasket 27 is sleeved on the first water passage portion 20 and abuts against the inner wall of the water passage hole 14.

[0051] Figure 6 and Figure 7 show a schematic diagram of the water outlet structure when the operating member 3 in this embodiment has not been pressed. As Figure 6 and Figure 7 As shown, when the operating member 3 has not been pressed, at this time, the first water passage portion 20 is in clearance fit with the water passage hole 14, and all the water passage segments 24 are located on the side of the water passage hole 14 close to the second water passage cavity 17. At this time, water cannot flow from the first water passage cavity 16 to the second water passage cavity 17.

[0052] Figure 8 and Figure 9Shows a schematic diagram of the water outlet structure when the operating member 3 is pressed to the first gear in this embodiment, as Figure 8 and Figure 9 shown. At this time, the first water passage portion 20 is in clearance fit with the water passage hole 14, and one of the water passage segments 24 extends into the first water passage chamber 16. The water passage groove 25 of this water passage segment 24 communicates the first water passage chamber 16 and the second water passage chamber 17. In this embodiment, when the operating member 3 is pressed to the first gear, there are two water passage grooves 25 that communicate the first water passage chamber 16 and the second water passage chamber 17.

[0053] Figure 10 and Figure 11 Shows a schematic diagram of the water outlet structure when the operating member 3 is pressed to the second gear in this embodiment, as Figure 10 and Figure 11 shown. At this time, the first water passage portion 20 is in clearance fit with the water passage hole 14, and only one water passage segment 24 extends into the second water passage chamber 17. The water passage groove 25 of this water passage segment 24 communicates the first water passage chamber 16 and the second water passage chamber 17. In this embodiment, when the operating member 3 is pressed to the second gear, there are four water passage grooves 25 that communicate the first water passage chamber 16 and the second water passage chamber 17.

[0054] Figure 12 and Figure 13 Shows a schematic diagram of the water outlet structure when the operating member 3 is pressed to the third gear in this embodiment, as Figure 12 and Figure 13 shown. All the water passage segments 24 are located in the first water passage chamber 16. At this time, the first water passage portion 20 is far from the water passage hole 14, and the water flows out from the gap between the water passage hole 14 and the first water passage portion 20.

[0055] In this embodiment, the first water passage chamber 16 communicates with the second water passage chamber 17 through the water passage hole 14. The water passage hole 14 is in clearance fit with the first water passage portion 20. Due to the clearance fit between the water passage hole 14 and the first water passage portion 20, when there is no water passage groove 25 provided on the first water passage portion 20, the water flow cannot pass through the water passage hole 14.

[0056] In this embodiment, the first water passage portion 20 is provided with at least two water passage segments 24 along the water passage direction, and each water passage segment 24 is provided with a water passage groove 25 suitable for communicating the first water passage chamber 16 and the second water passage chamber 17. The water passage groove 25 is provided to guide the water flow from the first water passage chamber 16 through the water passage groove 25 to the second water passage chamber 17. The water passage groove 25 can communicate the first water passage chamber 16 and the second water passage chamber 17. When the valve stem 8 slides at the water passage hole 14, only when the water passage groove 25 communicates the first water passage chamber 16 and the second water passage chamber 17 can the water flow flow from the first water passage chamber 16 through the water passage groove 25 into the second water passage chamber 17, which is beneficial to adjusting whether water comes out by the position of the valve stem 8 at the water passage hole 14.

[0057] In this embodiment, along the water flow direction, the water passing areas formed by the water passing grooves 25 that can connect the first water passing cavity 16 and the second water passing cavity 17 on each water passing section 24 increase step by step. The larger the water passing area, the greater the amount of water that can flow out. The water passing grooves 25 are arranged on the outer edge of the rod body 18. Since the water passing holes 14 and the rod body 18 are in clearance fit, if the water passing grooves 25 do not communicate with the first chamber 16 and the second chamber 17, the water flow cannot flow into the second chamber 17 through the water passing grooves 25. The number of water passing grooves 25 on each water passing section 24 is fixed, and the water passing areas on each water passing section 24 are also fixed. When the valve rod 8 slides in the water passing holes 14, the water passing grooves 25 on the water passing section 24 located at the water passing holes 14 determine the water passing area. Along the water flow direction, the gradually increasing communication area of the water passing grooves 25 on each water passing section 24 is beneficial to the hierarchical regulation of the water volume.

[0058] In this embodiment, the second water passing part 21 is arranged at an interval from the inner wall of the water passing hole 14, so that as long as the second water passing part 21 communicates with the first water passing cavity 16 and the second water passing cavity 17, the water flow can flow out from the interval between the second water passing part 21 and the inner wall of the water passing hole 14. At this time, it is when the water passing surface is the largest and the water flow is the largest.

[0059] In this embodiment, the blocking part 19 is farther from the second end 23 than the first water passing part 20 and the second water passing part 21. When the blocking part 19 abuts against the water passing hole 14, it is beneficial to prevent the water flow from flowing out from the gap between the main body 7 and the operating part 3.

[0060] In this embodiment, the number of water passing grooves 25 on the water passing section 24 closer to the second end 23 is greater than the number of water passing grooves 25 on the water passing section 24 closer to the first end 22, so that the water passing area on the water passing section 24 closer to the second end 23 is always greater than the water passing area on the water passing section 24 closer to the first end 22. When the valve rod 8 moves away from the water flow direction, the water flow rate can increase step by step, which is beneficial to regulating the water flow rate.

[0061] In this embodiment, the operating part 3 drives the valve rod 8 to move, making it more convenient to control the movement of the valve rod 8.

[0062] In this embodiment, the operating part 3 is rotatably connected to the main body 7, and the valve rod 8 slides in the main body 7 due to the rotation of the operating part 3.

[0063] In this embodiment, the elastic member 9 is placed between the valve rod 8 and the main body 7, so that the valve rod 8 can slide along the water flow direction. When water discharge is not required, due to the elastic member 9 restoring its deformation, the blocking part 19 on the valve rod 8 is driven to approach and abut against the water passing hole 14, thereby controlling the closing of the water flow.

[0064] The above description of the specification and embodiments is used to explain the protection scope of the present application, but does not constitute a limitation on the protection scope of the present application.
