Description

Technical Field

[0001] This utility model relates to the field of shower head technology, and in particular to a flow control device for a water-saving stainless steel shower head faucet. Background Technology

[0002] With increasingly scarce water resources and growing environmental awareness, water conservation has become a crucial development direction for bathroom products. As appliances that use water frequently in daily life, the water-saving performance of showerheads is particularly important. Currently, stainless steel showerheads are popular due to their corrosion resistance, long lifespan, and high-end appearance. However, traditional designs often have the following shortcomings in terms of flow control:

[0003] 1. Limited adjustment precision: Most systems use simple mechanical knobs or levers to adjust the flow rate, making it difficult for users to precisely control the flow to the ideal low-flow water-saving state.

[0004] 2. Flow stability is affected by water pressure: When the water pressure of the water supply network fluctuates, the water flow of a regular showerhead will change accordingly. Low pressure may affect the experience, while high pressure will cause excessive flow and splashing, which not only wastes water but also reduces comfort.

[0005] To address the above problems, this utility model proposes a flow control device for a water-saving stainless steel shower faucet. Utility Model Content

[0006] Based on the existing problems with water-saving shower head technology, this utility model proposes a flow control device for a water-saving stainless steel shower head faucet.

[0007] This utility model proposes a flow control device for a water-saving stainless steel shower head, including a shower head body. A water inlet pipe is fixedly connected to the inlet end of the shower head body. An adjustment mechanism is provided on the body of the water inlet pipe. The adjustment mechanism includes a throttling component. A spring is fixedly connected to one end of the throttling component, and one end of the spring is fixedly connected to the inner wall of the water inlet pipe. A rack is arrayed on one outer surface of the throttling component. A mounting hole is provided in the body of the water inlet pipe. A worm gear meshes with the surface of the rack and rotates within the mounting hole. Conical teeth are symmetrically arranged on both sides of the worm gear. A fixed rod is rotatably connected to the body of the worm gear via a bearing. Both ends of the fixed rod are fixedly connected to the body of the water inlet pipe. A bevel gear meshes with the surface of one of the bevel teeth. A concentric ratchet is fixedly connected to the upper end of the bevel gear, and a knob is fixedly connected to the upper end of the ratchet.

[0008] Preferably, a protective cap is provided around the mounting hole, a connecting rod is rotatably connected to the inner wall of the protective cap, a locking block is rotatably connected to one end of the connecting rod, the surface of the locking block engages with the surface of the ratchet, an adjusting rod is rotatably connected to the outer surface of one end of the connecting rod via a bearing, a push plate is fixedly connected to one end of the adjusting rod, a second spring is rotatably connected to the side of the connecting rod, one end of the second spring is fixedly connected to the inner wall of the protective cap, a groove adapted to the surface of the adjusting rod is opened on the side of the protective cap, and the surface of the adjusting rod is slidably connected to the inner wall of the groove.

[0009] Preferably, the inner wall of the water inlet pipe is provided with a groove that matches the rack.

[0010] Preferably, the throttling component includes a pipe body, with piston rings fixedly connected to both ends of the pipe body, and water-saving components arranged in an array at one end of the pipe body. A sealing coating is applied between the outer surface of the piston rings and the inner wall of the water inlet pipe.

[0011] Preferably, the mounting hole is located between the two piston rings.

[0012] Preferably, the outlet end of the water inlet pipe is internally shaped like a frustum, and the surface of the water-saving component is adapted to the inner wall of the frustum shape.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up a protective cap and internal components such as connecting rods, locking blocks, adjusting rods, push plates, and springs, the locking blocks engage with the ratchet surface, restricting the ratchet from rotating freely and preventing accidental changes to the flow rate by touching the knob. When adjustment is needed, push the adjusting rod to drive the push plate, causing the connecting rod to rotate and disengage the locking blocks from the ratchet. After operation, springs reset the locking blocks, ensuring the stability of the flow rate after adjustment. At the same time, the protective cap protects the transmission components inside the mounting hole, reducing the influence of external moisture and impurities and extending the service life of the device.

[0015] 2. By setting up a throttling component, the piston rings at both ends of the pipe body cooperate with the sealing coating on the inner wall of the inlet pipe to enhance the sealing of the water flow channel in the inlet pipe and reduce leakage and seepage; the array rack and the water-saving component cooperate with the frustum-shaped water outlet to stably change the water flow area during movement, and the water-saving component is adapted to the frustum-shaped inner wall, which can effectively throttle and stabilize the water flow, improve the water-saving effect, and at the same time, the spring can assist the throttling component to reset, ensuring the reliability and smoothness of flow regulation.

[0016] 3. By setting up an adjustment mechanism, turning the knob drives the throttling component to move through the concentric ratchet, bevel gear, bevel tooth, and worm gear transmission. Combined with the frustum-shaped structure at the water outlet of the inlet pipe, the size of the water flow channel can be precisely adjusted to achieve flexible control of the shower head flow rate and save water. The transmission structure is stable, the operation is convenient, and the water output can be adjusted according to actual usage needs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-7 A flow control device for a water-saving stainless steel shower head includes a shower head body 1. A water inlet pipe 2 is fixedly connected to the water inlet end of the shower head body 1. An adjustment mechanism 3 is provided on the body of the water inlet pipe 2. The adjustment mechanism 3 includes a throttling component 31. A spring 32 is fixedly connected to one end of the throttling component 31. One end of the spring 32 is fixedly connected to the inner wall of the water inlet pipe 2. A rack 33 is arrayed on one outer surface of the throttling component 31. A mounting hole is opened in the pipe body of the water inlet pipe 2. A worm gear 34 is meshed on the surface of the rack 33. The worm gear 34 rotates in the mounting hole. Conical teeth 35 are symmetrically arranged on both sides of the worm gear 34. A fixed rod 36 is rotatably connected to the body of the worm gear 34 through a bearing. The two ends of the fixed rod 36 are fixedly connected to the pipe body of the water inlet pipe 2. A bevel gear 37 is meshed on the surface of one of the bevel teeth 35. A concentric ratchet 38 is fixedly connected to the upper end of the bevel gear 37. A knob 39 is fixedly connected to the upper end of the ratchet 38.

[0027] In this embodiment, a protective cap 314 is provided around the mounting hole. A connecting rod 310 is rotatably connected to the inner wall of the protective cap 314. A locking block 3101 is rotatably connected to one end of the connecting rod 310. The surface of the locking block 3101 engages with the surface of the ratchet 38. An adjusting rod 311 is rotatably connected to the outer surface of one end of the connecting rod 310 via a bearing. A push plate 312 is fixedly connected to one end of the adjusting rod 311. A second spring 313 is rotatably connected to the side of the connecting rod 310. One end of the second spring 313 is fixedly connected to the inner wall of the protective cap 314. A groove adapted to the surface of the adjusting rod 311 is opened on the side of the protective cap 314. The surface of the adjusting rod 311 is slidably connected to the inner wall of the groove.

[0028] Specifically, the protective cap 314 covers the ratchet 38 and other transmission components, forming a protective space. For adjustment, pushing the push plate 312 moves the adjusting rod 311, pulling the connecting rod 310 to rotate around the pivot on the inner wall of the protective cap 314. The locking block 3101 disengages from the ratchet tooth groove, releasing the lock. After adjustment, releasing the push plate 312 resets the spring 313, and the locking block 3101 re-locks the ratchet 38, ensuring stable position after flow adjustment and preventing accidental activation of the knob 39 during showering to change the water output state.

[0029] The inner wall groove of the water inlet pipe 2 is adapted to the rack 33 of the throttling component 31 to form a guide structure. When the worm wheel 34 rotates, the worm wheel teeth mesh with the rack 33. With the help of the linear constraint of the groove, the throttling component 31 is forced to move axially along the water inlet pipe to avoid the throttling component from deflecting or getting stuck.

[0030] The piston rings at both ends of the throttling component 31, combined with a sealing silicone coating, fit tightly against the inner wall of the inlet pipe 2, dividing the inside of the inlet pipe into a "transmission chamber" and a "water flow chamber." The piston rings not only prevent water from leaking into the transmission chamber, protecting components such as the worm gear and bevel gear, but also, with the help of the water-saving component at one end of the pipe, change the overlap area between the water-saving component and the inner wall of the truncated cone at the outlet end of the inlet pipe when the pipe moves. When closer to the narrow opening of the truncated cone, the water flow area is small, and the flow rate is reduced; when farther away, the water flow area is large, and the flow rate is increased, achieving the dual functions of sealing against leakage and precise throttling.

[0031] In this embodiment, the inner wall of the water inlet pipe 2 is provided with a groove that matches the rack 33.

[0032] Specifically, when the worm gear 34 rotates, the rack 33 and the slide groove cooperate to ensure that the throttling component 31 slides smoothly along a straight line, avoiding deviation that could lead to seal failure or flow regulation jamming, thus improving the reliability of the structure's operation.

[0033] In this embodiment, the throttling component 31 includes a pipe body, with piston rings fixedly connected to both ends of the pipe body. Water-saving components are arranged in an array at one end of the pipe body, and a sealing coating is applied between the outer surface of the piston rings and the inner wall of the water inlet pipe 2.

[0034] Specifically, the piston rings at both ends of the throttling component, in conjunction with the sealing coating, fill the gap between the inner wall of the inlet pipe 2 and the piston rings, forming a reliable seal to prevent water leakage. The water-saving component at one end of the pipe body, when the pipe body moves, cooperates with the frustum-shaped inner wall of the outlet end of the inlet pipe 2 to change the water flow area: when it is close to the small diameter end of the frustum, the channel narrows and the flow rate decreases; when it is far away, the channel widens and the flow rate increases, thus accurately controlling the water output to achieve water saving.

[0035] In this embodiment, the mounting hole is located between the two piston rings.

[0036] Specifically, the mounting hole is located between the two piston rings. The movement of the two piston rings always keeps the mounting hole between them, so that the transmission components such as the worm gear 34 and the bevel gear 35 are in a relatively dry and stable environment. This not only avoids water immersion affecting the life of the transmission components, but also uses the sealing of the piston rings to ensure the independence of the water flow channel in the water inlet pipe 2, so that the transmission and water flow control do not interfere with each other.

[0037] In this embodiment, the inside of the water outlet of the water inlet pipe 2 is shaped like a frustum, and the surface of the water-saving component is adapted to the inner wall of the frustum.

[0038] Specifically, the inner wall of the water outlet of the inlet pipe 2 is frustoconical and adapted to the surface of the water-saving component, such as a wedge-shaped or stepped structure. When the throttling component 31 moves, the water-saving component slides in the frustoconical cavity. By changing the size of the gap between the two, the water flow speed and flow rate are linearly adjusted. The frustoconical design can also pre-guide the water flow, allowing the water-saving component to control the flow more precisely, while reducing water flow impact noise and improving the shower experience.

[0039] Operating principle:

[0040] During showering, water flows out through the inlet pipe 2 and the shower head body 1. If the water pressure is high during rinsing, the knob 39 is turned, which drives the concentric ratchet 38 and bevel gear 37 to rotate. The bevel gear 37 meshes with the bevel teeth 35, causing the worm gear 34 to rotate around the fixed rod 36. The worm gear 34 drives the throttling component 31 to move axially along the sliding groove on the inner wall of the inlet pipe 2 through the rack 33. At this time, the water-saving component of the throttling component 31 cooperates with the frustum-shaped inner wall of the outlet end of the inlet pipe, changing the water flow area to adjust the flow rate and reduce the size of the inlet pipe 2. The cross-sectional area of ​​the water outlet is increased to reduce water pressure impact. If the water pressure is low, the push plate 312 drives the adjusting rod 311 to slide along the groove, thereby driving the connecting rod 310 to rotate, causing the locking block 3101 to disengage from the ratchet 38, releasing the lock on the ratchet 38. The spring 1 32 drives the throttling component 31 to reset, the water pressure increases, and after the push plate 312 is released, the spring 2 313 resets the connecting rod 310, and the locking block 3101 re-engages into the tooth groove of the ratchet 38, restricting its free rotation, and the water pressure remains stable.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
