Description

Technical Field

[0001] This invention belongs to the technical field of bathroom products and relates to an overhead shower head. Background Technology

[0002] A overhead shower head is installed on the ceiling of the shower area, providing a large water coverage area. It creates a curtain of water flow through multiple water outlets or a panel for showering. Overhead shower heads include single-function shower heads with a single water outlet and multi-function shower heads with multiple water outlets. For multi-function shower heads, a switching valve is installed on the shower head to switch the water flow.

[0003] For example, a water path switching device disclosed in Chinese patent literature (publication number CN102366734A) includes a water path mechanism, an execution part, an operation part, and a transmission part. The water path mechanism includes a shower head body with one inlet and two outlets. The execution part is mounted within the shower head body and includes a movable component and a return spring. The movable component, through relative movement with the shower head body, switches at least two outlets to connect to the inlet. The operation part includes a handle, which may be located on the shower head body or in another location outside the shower head body. The transmission part includes a steel wire rope, one end of which is connected to the movable component, and the other end is connected to the handle. Relative rotation of the handle moves the steel wire rope, causing the movable component to move relative to the shower head body. When the handle is released, the movable component returns to its original position under the action of the return spring, thus achieving the back-and-forth switching of the water path.

[0004] Because the return spring is installed inside the showerhead body, water comes into contact with it when the showerhead is running. After the water stops, some water inside the showerhead body flows out from the showerhead panel under gravity, while air enters and comes into contact with the return spring. The return spring is easily corroded in the presence of water and air, causing its restoring force to weaken after long-term use. This can lead to failure to return to its original position, resulting in water circuit switching failure and affecting the long-term stability of the water circuit switching device. To maintain good stability of the water circuit switching device over the long term, an easy technical solution is to modify the return spring. For example, an elastic insulating sleeve, such as a corrugated rubber tube, could be added around the return spring, or a more corrosion-resistant return spring could be used. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an overhead shower head, which solves the technical problem of how to improve the long-term stability of the overhead shower head.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A top-mounted shower head includes an inverted L-shaped shower rod, with a shower head body connected to the upper end of the shower rod. A switching valve is connected to the shower head body, and an operating component is provided on the shower rod. The switching valve is characterized in that it is a valve that switches the water path by rotating a valve stem, and a rope pulley is fixedly connected to the valve stem. A first pulley and a second pulley are connected to the corner of the shower rod, and a pulley assembly is connected to the lower end of the shower rod. A circular transmission rope is sequentially wound around the pulley assembly, the first pulley, the rope pulley, and the second pulley. The operating component is fixedly connected to the transmission rope or connected to the pulley assembly. The transmission rope is fixedly connected to the rope pulley at a fixed point on the circumference of the rope pulley.

[0008] When a water circuit needs to be switched, the drive mechanism moves the transmission rope. The transmission rope moves on the first pulley, the second pulley, and the pulley assembly, synchronously driving the rope wheel to rotate. The rope wheel then drives the valve stem of the switching valve to rotate, causing the switching valve to actuate and switch the water circuit. When it is necessary to return to the original water circuit, since the transmission rope is looped and the switching valve switches the water circuit by rotating the valve stem, the reverse drive mechanism moves the transmission rope in the opposite direction, causing the valve stem of the switching valve to rotate in the opposite direction.

[0009] Because the drive rope is looped, force is transmitted through it during the switching of water paths, enabling accurate operation of the switching valve and achieving precise and stable water path switching. Furthermore, the drive rope is wound around the first pulley, rope pulley, second pulley, and pulley assembly. This arrangement prevents the drive rope from being corroded by water from the switching valve and the shower head body. It also ensures the drive rope is tensioned on at least four pulleys, distributing the force and reducing stress concentration, thus extending the rope's lifespan. The self-tensioning effect of the first pulley, rope pulley, second pulley, and pulley assembly ensures the stability and synchronization of the drive rope's operation. Simultaneously, the rope pulley is guided by the first and second pulleys on both sides, balancing the lateral tension of the drive rope on the pulley and reducing the radial load on the valve stem, allowing for smooth valve stem rotation. Additionally, the drive rope experiences minimal friction during movement, ensuring structural stability over long-term use. Therefore, this overhead shower head offers improved long-term stability.

[0010] In the above-mentioned overhead shower head, a water inlet seat is sleeved and fixed on the outside of the switching valve. The water inlet seat includes a top cover that protrudes upward from the center of the top wall. The outer surface of the top cover has a water inlet pipe facing the corner of the shower rod. The rope wheel is embedded in the center of the top wall of the top cover. There are notches on both sides of the rope wheel on the top wall of the top cover, and the transmission rope is led out from the rope wheel through the notches and located on both sides of the water inlet pipe.

[0011] The top wall of the top cover protrudes upwards and has a water inlet pipe to stabilize the top cover structure. The top cover is not only used for water inlet, but also to accommodate the positioning rope wheel, so that the top spray shower can smoothly enter water and switch water paths. Moreover, the rope wheel and the transmission rope do not interfere with the water inlet pipe, so that the top spray shower can work stably for a long time.

[0012] In the aforementioned overhead shower head, the water inlet seat also includes a cylindrical bottom tube. The switching valve is inserted and fixedly connected in the bottom tube. The bottom tube has a U-shaped cross-section on one side. A cylindrical intermediate tube is inserted between the inner and outer walls of the bottom tube. The upper end of the intermediate tube is inserted and fixedly connected to the top cover to form a seal. The lower end of the intermediate tube is fixedly connected to the bottom tube to form a seal. The inner side of the intermediate tube has a protruding inner ring. The inner ring forms a seal with both the top cover and the inner wall of the bottom tube. A central through hole is opened on the inner ring. An inner through hole is opened on the inner wall of the bottom tube. The water inlet pipe is connected to the switching valve through the central through hole and the inner through hole.

[0013] This design of the inlet seat not only allows the inlet seat to connect with the switching valve for smooth water intake, but also ensures the stability of the inlet seat structure, making the switching valve work stably. In addition, the inlet seat can buffer the water flow, reducing the direct impact of the water flow on the switching valve, thus ensuring the long-term stable operation of the switching valve.

[0014] In the aforementioned overhead shower head, the switching valve includes a valve body, which is a cylindrical structure with a cylindrical upper part and a spherical lower part. A ball joint is provided at the top of the shower head body. The upper part of the valve body is inserted into and fixed in the inner wall of the bottom cylinder, and the lower part of the valve body is inserted into the ball joint. The upper part of the valve body has an inlet that communicates with the inner through hole, and the lower part of the valve body has a first outlet and a second outlet. The valve core includes a moving ceramic plate, a stationary ceramic plate, and a water distribution element stacked sequentially from top to bottom in the valve body. The valve stem of the switching valve is connected to the moving ceramic plate and can drive the moving ceramic plate to rotate. The rotation of the moving ceramic plate can connect the inlet with the first outlet and / or the second outlet.

[0015] The upper part of the valve body is cylindrical, ensuring stable fixation between the valve body and the inlet seat. The lower part of the valve body is spherical, connecting to a ball joint, allowing the shower head to rotate and facilitating adjustment of the shower head panel's orientation. The valve core features a combination of moving and stationary ceramic discs, ensuring accurate water path switching and a long service life. The switching valve can achieve three water output modes: water only from the first outlet, water only from the second outlet, and water from both the first and second outlets simultaneously.

[0016] In the aforementioned overhead shower head, the ball joint includes a central tube, a connecting cylinder, and a locking cap. The inner side of the connecting cylinder has a protruding retaining ring. The central tube is inserted into the connecting cylinder and forms a seal with the retaining ring. The lower part of the valve body is inserted into the connecting cylinder. The locking cap is fitted onto and fixed to the connecting cylinder, limiting the lower part of the valve body within the connecting cylinder. A ball seat is fixed on the retaining ring above the central tube. The ball seat abuts against the lower part of the valve body, separating the first water outlet and the second water outlet. A water passage hole is provided on the retaining ring. The shower head body has a first water outlet and a second water outlet. The first water outlet is connected to the first water outlet through the water passage hole, and the second water outlet is connected to the second water outlet through the ball seat and the central tube.

[0017] The ball joint not only allows the shower head panel to be adjusted in orientation, but also ensures water diversion, enabling the shower head to switch between multiple water paths. At the same time, the stable structure helps ensure the long-term stable operation of the overhead shower head.

[0018] In the aforementioned overhead shower head, a locking device is provided between the drive rope and the sheave. The locking device includes a locking screw and a locking pin. The locking screw passes through and is threaded onto one side of the sheave groove wall, and the locking pin passes through the other side of the sheave groove wall. The locking screw and the locking pin are coaxially arranged and abut against each other, and the drive rope passes through the locking pin.

[0019] When the locking screw is tightened, the locking pin presses the drive rope against the groove wall on the other side of the pulley, fixing the drive rope and the pulley at a fixed point on the circumference of the pulley. The locking device ensures a stable connection between the drive rope and the pulley, which is beneficial for long-term stability.

[0020] In the above-mentioned overhead shower head, the top of the rope pulley has a protruding upper ring, which is inserted into the top wall of the top cover, and a bushing is provided between the upper ring and the top wall of the top cover.

[0021] The upper convex ring positions the top of the rope wheel on the top wall of the top cover, ensuring stable rotation of the rope wheel. The bushing reduces friction and wear, allowing the rope wheel to rotate smoothly. This facilitates smooth and stable switching of the water path of the overhead shower and contributes to the long-term stability of the overhead shower.

[0022] In the aforementioned overhead shower head, the shower rod includes a tubular vertical pipe and a horizontal pipe. A water inlet pipe is fixedly connected to the water inlet pipe, which passes through the horizontal pipe. The first and second pulleys are located inside the shower rod and on either side of the water inlet pipe. The top cover is located inside the horizontal pipe, and the lower side wall of the horizontal pipe is clamped and fixed between the top cover and the outer wall of the bottom tube. The drive rope is sealed inside the shower rod. The water inlet seat is supported and fixed by the water inlet pipe and the horizontal pipe, ensuring stable fixation and contributing to the long-term stability of the overhead shower head.

[0023] The drive rope is located outside the water inlet pipe, preventing water from corroding it. The drive rope is protected inside the shower rod, the pulley is located inside the horizontal pipe, and the first and second pulleys are located inside the shower rod. This reduces the impact of the external environment on the drive rope, pulley, first and second pulleys, ensuring long-term stable operation of the drive rope.

[0024] In the above-mentioned overhead shower head, the outer side of the top cover also has a protruding positioning head, which faces opposite to the water inlet pipe and is inserted into the end cap of the horizontal pipe.

[0025] The positioning head has a positioning function, preventing the top cover from rotating in the horizontal pipe, and also forms a support point for fixing the water inlet seat on the horizontal pipe, making the water inlet seat stable and ensuring the stable use of the top spray shower.

[0026] In the above-mentioned overhead shower head, an upper support and a lower support are fixedly connected to both ends of the vertical pipe, respectively. The upper support has a boss located inside the vertical pipe on its front side. The water inlet pipe is inserted and fixed on the boss. A water inlet connector is inserted and connected to the back of the upper support. The boss has grooves on both sides of the water inlet pipe, and the first pulley and the second pulley are respectively installed in the corresponding grooves.

[0027] The upper support is not only used to install the water inlet pipe and water inlet connector to enable water intake, but also to connect the first pulley and the second pulley to isolate the transmission rope from the water inlet pipe and ensure smooth rotation of the transmission rope, making the overhead shower head compact and stable in operation.

[0028] In the aforementioned overhead shower head, a sliding seat located inside the vertical pipe is fixedly connected to the front of the lower support. A pulley seat located below the sliding seat is also fixedly connected to the lower support. The pulley is mounted on the pulley seat. The transmission rope extends from the pulley through the pulley seat and is located on both sides of the sliding seat. The operating component includes a slider embedded in the sliding seat that can slide up and down. One side of the slider has a protruding fixing part, and the transmission rope is fixedly connected to the fixing part. A push button is also fixedly connected to the slider. The push button drives the slider to slide, thereby causing the transmission rope to reciprocate, making water path switching convenient. This arrangement is compact and provides stable operation.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. The valve stem of the switching valve is fixed with a rope pulley. The transmission rope is looped. The first and second pulleys are located at the corner of the shower rod. The pulley assembly is located at the lower end of the shower rod. The transmission rope is sequentially wound around the first pulley, the rope pulley, the second pulley, and the pulley assembly. The transmission rope is fixedly connected to a fixed point of the rope pulley. The reciprocating motion of the transmission rope drives the switching valve to rotate and switch the water path. The transmission rope does not contact the water path and is not affected by the water inlet pipe. The transmission friction is small, which not only reduces the loss of operating force and makes the operation easy, but also improves the stability of long-term operation.

[0031] 2. The top cover of the water inlet seat is used to position the rope wheel and connect the water inlet pipe, separating the rope wheel from the water inlet pipe so that the overhead shower can smoothly take in water and switch water paths. Moreover, the rope wheel and the drive rope do not interfere with the water inlet pipe, so that the overhead shower can work stably for a long time.

[0032] 3. The bottom and middle cylinders of the water inlet seat cooperate with the top cover to connect the water inlet pipe to the switching valve. At the same time, it can buffer the water flow and reduce the direct impact of the water flow on the switching valve, which is conducive to the long-term stable operation of the overhead shower.

[0033] 4. The lower part of the valve body of the switching valve is spherical. With the help of a ball joint, it can not only divert the flow but also adjust the orientation of the shower panel. The structure is stable and easy to use.

[0034] 5. This overhead shower head has a compact overall structure, a simple transmission structure, low operating force loss and easy operation. Moreover, it is simple and reliable in structure, easy to process, convenient to assemble and control precisely. Attached Figure Description

A venting hole 8e2 is provided on the side wall of the venting cylinder 8e, located below the reducing ring 8e1. When water passes through the flow gap between the reducing ring 8e1 and the central tube 8a, it is accelerated, and a negative pressure is formed according to Bernoulli's principle, causing outside air to be drawn into the venting cylinder 8e through the venting hole 8e2. The air mixes with the water to form bubbles.

[0051] like Figure 2 and Figure 6As shown, a sliding seat 18 located inside the vertical tube 3a is fixedly connected to the front of the lower support 3c. A pulley seat 19 located below the sliding seat 18 is also fixedly connected to the lower support 3c. A pulley component 12 is mounted on the pulley seat 19. The pulley component 12 consists of two small pulleys arranged side by side or one large pulley. The transmission rope 7 is led out from the pulley component 12 through the pulley seat 19 and is located on both sides of the sliding seat 18. The operating component 6 includes a slider 6a that is embedded in the sliding seat 18 and can slide up and down. One side of the slider 6a has a protruding fixing part 6a1 that extends out of the sliding seat 18. The transmission rope 7 is fixedly connected to the fixing part 6a1. A push button 6b is also fixedly connected to the slider 6a and is located on the outside of the vertical tube 3a.

[0052] like Figure 7 , Figure 8 and Figure 2 As shown, the transmission rope 7 is fixed to the slider 6a and the rope wheel 9 by a locking device 20. The locking device 20 includes a locking screw 20a and a locking pin 20b. A fixing point 9b is provided on the rim of the rope wheel 9. The locking screw 20a passes through and is threaded into one side of the groove wall of the rope wheel 9, and the locking pin 20b passes through the other side of the groove wall of the rope wheel 9. The locking screw 20a and the locking pin 20b are coaxially arranged and abut against each other. The transmission rope 7 passes through the locking pin 20b. Tightening the locking screw 20a presses and fixes the transmission rope 7 onto the rope wheel 9. At slider 6a, a locking screw 20a is threaded onto the fixing part 6a1 and perpendicular to the transmission rope 7. A locking pin 20b is inserted into the fixing part 6a1. The locking screw 20a and the locking pin 20b are coaxially arranged and abut against each other. The transmission rope 7 passes through the fixing part 6a1 and the locking pin 20b. Tightening the locking screw 20a presses the transmission rope 7 firmly onto the slider 6a. Alternatively, the transmission rope 7 can be fixed to the fixing point 9b of the slider 6a and the pulley 9 by welding.

[0053] Typically, a ceiling-mounted water spray pipe is pre-embedded in the bathroom wall. A ceiling-mounted water spray switch valve is connected to the ceiling-mounted water spray pipe, and the outlet end of the ceiling-mounted water spray pipe is connected to the inlet connector 17 on the upper support 3b. When the ceiling-mounted water spray switch valve is opened, water enters the inlet pipe 2 from the inlet connector 17, then enters the inlet seat 5 from the water inlet pipe 5a1, passes through the middle through hole 5c1a of the intermediate cylinder 5c and the inner through hole 5b1 of the bottom cylinder 5b, and then enters the switching valve 4 through the inlet 4a1 of the switching valve 4. If the fan-shaped groove 4b1a of the moving ceramic disc 4b1 is only connected to the first water passage hole of the stationary ceramic disc 4b2, the water flows through the first water passage hole of the stationary ceramic disc 4b2, the first water distribution hole of the water divider, and the first water passage channel of the water divider 4b3, and then flows out from the first outlet 4a2 of the valve body 4a. It then passes through the water passage hole 8b1a of the connecting cylinder 8b, and through the flow gap between the reducing ring 8e1 and the central pipe 8a, drawing in outside air. Finally, it enters the shower body 1 and flows out from the first outlet 1a. If the fan-shaped groove 4b1a of the moving ceramic disc 4b1 is only connected to the second water passage hole of the stationary ceramic disc 4b2, the water flows through the second water passage hole of the stationary ceramic disc 4b2, the second water distribution hole of the water divider, and the second water passage channel of the water divider 4b3, and then flows out from the second outlet 4a3 of the valve body 4a. It then passes through the central pipe 8a, enters the shower body 1, and flows out from the second outlet 1b. If the fan-shaped groove 4b1a of the moving ceramic piece 4b1 is connected to both the first water passage hole and the second water passage hole, then water will flow out from both the first water outlet 1a and the second water outlet 1b at the same time.

[0054] like Figure 2 As shown, water is flowing from the first outlet 1a at this time, with the push button 6b at the bottom. The fan-shaped groove 4b1a of the moving ceramic plate 4b1 is connected to the first water passage hole of the stationary ceramic plate 4b2. When the water path needs to be switched, the push button 6b is driven to slide upward, causing the transmission rope 7 to move. The transmission rope 7 moves on the first pulley 10, the second pulley 11, and the pulley assembly 12, driving the rope wheel 9 to rotate. The rope wheel 9 then drives the valve stem 4c of the switching valve 4 to rotate, which in turn drives the moving ceramic plate 4b1 to rotate. When the push button 6b is in the middle position, the fan-shaped groove 4b1a of the moving ceramic plate 4b1 is connected to both the first and second water passage holes, and water flows out from both the first outlet 1a and the second outlet 1b simultaneously. When the push button 6b is at the top, the fan-shaped groove 4b1a of the moving ceramic plate 4b1 is only connected to the second water passage hole, and water flows out from the second outlet 1b. When it is necessary to return to the original water path, since the transmission rope 7 is in a loop and the switching valve 4 is a rotary valve, the reverse drive push button 6b causes the transmission rope 7 to move in the opposite direction, which in turn drives the valve stem 4c of the switching valve 4 to rotate in the opposite direction.

[0055] Example 2

[0056] The basic structure is the same as in Embodiment 1, except that: a rack that can slide up and down is provided on the sliding seat 18, and a protruding fixing part 6a1 is provided on one side of the rack. The transmission rope 7 is fixedly connected to the fixing part 6a1. A knob is also rotatably connected to the sliding seat 18, and a gear that meshes with the rack is fixedly connected to the knob. Rotating the knob drives the rack to move up and down through the gear, thereby driving the transmission rope 7 to move back and forth to achieve water path switching.

[0057] Example 3

[0058] The switching valve 4 is a three-way ball valve. The inlet pipe 2 is connected to the inlet end of the three-way ball valve. A sealing cap is installed on the top of the mounting cylinder 8f.

The insert cylinder 1c extends out of the sealing cap and connects to the second outlet end of the three-way ball valve. Other structures are basically the same as in Embodiment 1.

[0059] Example 4

[0060] In the water inlet seat 5, the bottom cylinder 5b and the intermediate cylinder 5c are removed. The upper structure of the valve body 4a and the water inlet 4a1 are adjusted to adapt to the change. The valve body 4a of the switching valve 4 is inserted into the top cover 5a and fixed. The water inlet pipe 5a1 of the top cover 5a is connected to the water inlet 4a1 of the valve body 4a. In the ball joint 8, the vent cylinder 8e is removed, so that the connecting cylinder 8b is directly fixedly connected to the mounting cylinder 8f. Other structures are basically the same as in Embodiment 1.

[0061] Example 5

[0062] The locking device 20 includes a locking screw 20a. At the pulley 9, the locking screw 20a is threaded onto one side of the pulley groove wall, and the end of the locking screw 20a abuts against the drive rope 7. Tightening the locking screw 20a presses the drive rope 7 firmly against the other side of the pulley groove wall. At the slider 6a, the locking screw 20a is threaded onto the fixing part 6a1 and is perpendicular to the drive rope 7. The drive rope 7 passes through the fixing part 6a1, and the end of the locking screw 20a abuts against the drive rope 7. Tightening the locking screw 20a presses the drive rope 7 firmly against the slider 6a. Other structures are basically the same as in Embodiment 1.

[0063] Example 6

[0064] The pulley component 12 is a pulley on which the transmission rope 7 is wound to maintain tension. Both ends of the transmission rope 7 are fixed to the pulley. The operating component 6 includes a knob, and the pulley is mounted and fixed on the central axis of the knob. Rotating the knob causes the pulley to rotate, thereby driving the transmission rope 7 to reciprocate. Alternatively, the operating component 6 is a lever, one end of which is fixedly connected to the spokes of the pulley. Driving the lever along the circumference of the pulley causes the pulley to rotate, thereby driving the transmission rope 7 to reciprocate.
