Description

Technical Field

[0001] This invention relates to the field of smart bathroom technology, and in particular to a manual water pattern switching device, a spray gun, a smart toilet seat, and a smart toilet. Background Technology

[0002] The cleaning function of a smart toilet relies on its spray gun. The spray gun needs to be able to switch between different water patterns, such as concentrated water jets and gentle showers, to achieve multiple cleaning modes such as posterior wash and feminine wash, thereby improving the user experience.

[0003] Traditional solutions integrate an electric drive module consisting of a motor, reduction gears, and control circuitry inside the spray gun or at the water outlet. This module uses electrical signals to control a switching mechanism to align with different nozzles. While this type of electric switching solution achieves automated operation, its complex structure, containing numerous precision electronic and mechanical components, results in high production costs and energy consumption. Furthermore, under prolonged use or harsh conditions such as humidity and vibration, the motor and circuitry are prone to failure. Damage to these components can render the entire water pattern switching function ineffective, impacting cleaning operations and user experience.

[0004] The information disclosed above in the background art of this application is only used to understand the background of the concept of this application, and may contain information that does not constitute prior art. Summary of the Invention

[0005] Therefore, it is necessary to provide a manual water pattern switching device, a spray gun, a smart toilet seat, and a smart toilet to address the above problems.

[0006] This application provides a manual water pattern switching device, comprising:

[0007] The housing has a water outlet at its top and is used to connect to the end of the spray gun.

[0008] The nozzle is disposed inside the housing and has a first spray hole and a second spray hole.

[0009] An adjusting member is rotatably disposed within the housing. One end of the adjusting member is connected to the nozzle, and the other end of the adjusting member is exposed outside the housing and used for operation to drive the nozzle to rotate relative to the housing to a first position and a second position. In the first position, the first nozzle is aligned with the water outlet; in the second position, the second nozzle is aligned with the water outlet.

[0010] The aforementioned manual water pattern switching device can achieve at least the following beneficial effects:

[0011] The manual water pattern switching device of this application is connected to the end of the spray gun through a housing. It is operated by an adjustment component exposed outside the housing, which drives the nozzle to rotate relative to the housing to a first position or a second position. When the nozzle is in the first position, the first nozzle is aligned with the water outlet to spray the first water pattern. When the nozzle is in the second position, the second nozzle is aligned with the water outlet to spray the second water pattern. Thus, switching between two different water patterns can be achieved simply by manually rotating the adjustment component. This structure has wide adaptability. It can be used as an independent manual switching solution on simple spray guns without motors to reduce overall cost and complexity, eliminating the drive motor, control circuit and complex transmission mechanism required by traditional electric switching, which greatly simplifies the overall structure of the device and reduces manufacturing costs and energy consumption. It can also be integrated into spray guns with motors as a backup or auxiliary switching module, providing an intuitive and convenient quick switching option when the motor drive system is working normally, and serving as a reliable emergency manual switching guarantee when the motor or other electronic drive components fail. This ensures that the spray gun can reliably switch water patterns under various working conditions and configurations, significantly improving the product's functional redundancy, environmental adaptability and user satisfaction.

[0012] In some embodiments, an adjustment hole is provided on the side of the housing away from the spray gun. The adjustment member is rotatably inserted through the adjustment hole, and an operating protrusion is provided at the end of the adjustment member away from the nozzle. The operating protrusion is used to operate and drive the rotation of the adjustment member and the nozzle. By providing an independent adjustment hole, precise and stable rotational support is provided for the adjustment member, ensuring the accuracy of axial positioning and smoothness of rotation during manual operation, effectively preventing the adjustment member from swaying or jamming due to uneven force. At the same time, the operating protrusion at the end of the adjustment member significantly increases the working area and force fulcrum of the hand or tool, allowing the operator to apply rotational torque more effortlessly and precisely. This reliably drives the nozzle inside the housing to rotate to the predetermined position through the adjustment member, achieving convenience, effortlessness, and high reliability in water pattern switching operation, and further optimizing the human-machine interaction experience.

[0013] In some embodiments, the operating protrusion has two opposing operating surfaces along the radial direction of the adjustment hole. These opposing operating surfaces provide a clear and stable gripping or force application position for the fingers of the hand, allowing the operator to apply rotational torque to the operating protrusion more evenly and effectively by pinching or applying force in opposite directions, thus making operation more convenient.

[0014] In some embodiments, a limiting rib is formed on the outer peripheral surface of the nozzle near the adjusting hole. The limiting rib is engaged with the periphery of the adjusting hole to restrict the axial movement of the nozzle in the adjusting hole. By directly setting the limiting rib on the nozzle and using it to engage with the periphery structure of the adjusting hole on the housing, a simple, reliable, and compact mechanical limit is provided for the nozzle in the axial direction without adding extra parts. This effectively prevents the nozzle from rotating under the action of the adjusting component or from axially shifting or accidentally dislodging under water pressure impact. It ensures the stability of the nozzle's axial position within the housing, thereby guaranteeing the long-term accuracy and consistency of the alignment between the first and second spray holes and the outlet of the housing, and improving the structural stability and operational reliability of the entire manual water pattern switching device.

[0015] In some embodiments, the adjusting member is integrally formed with the nozzle. By integrating the adjusting member and the nozzle into an inseparable whole, any possible assembly gaps, loose connections, or relative rotational errors between the two are completely eliminated. This ensures that the rotational torque applied by the operating protrusion is directly, losslessly, and synchronously transmitted to the nozzle, thereby greatly improving the response speed, control accuracy, and transmission reliability of the water pattern switching action. At the same time, the integrally formed structure reduces the number of parts, simplifies the assembly process, reduces the defect rate caused by the accumulation of tolerances in the fit of multiple parts, and enhances the overall structural strength and durability of the moving component in long-term use. This optimizes the reliability and cost-effectiveness of the product from both manufacturing and performance perspectives.

[0016] In some embodiments, the adjusting component is detachably connected to the nozzle. By employing detachable connection methods, such as threaded connections, snap-fit ​​connections, or keyway engagements, a modular design for both the adjusting component and the nozzle is achieved. This structure allows for independent replacement or repair of the adjusting component or nozzle without replacing the entire assembly, thereby improving product maintainability and lifespan, and reducing long-term operating costs.

[0017] In some embodiments, the manual water pattern switching device further includes a rotating shaft rotatably inserted through the housing. The rotating shaft is located on the side of the nozzle away from the adjusting member, and a water supply pipe is formed inside the rotating shaft. The rotating shaft is connected to and communicates with the nozzle to supply water to the nozzle. The adjusting member is coaxially arranged with the rotating shaft. By introducing a rotating shaft with an internally formed water supply pipe as an independent water supply and rotation support component, the water supply function of the nozzle and the operation function of the adjusting member are structurally separated and integrated. The rotating shaft rotatably inserted through the housing provides a stable and reliable rotation support point on the other side of the nozzle for the entire device, optimizing the stress structure and enhancing the stability during rotation. The water supply pipe formed inside the rotating shaft allows water from the water source to be stably and directly delivered to the nozzle through the internal structure of the rotating shaft itself, achieving complete unification and internalization of the water supply path and the rotation axis. This avoids the risks of entanglement, wear, space occupation, or leakage that may occur when connecting external water pipes at rotating parts, and simplifies the layout of external pipelines.

[0018] In some embodiments, one end of the shaft extending into the housing is detachably connected to the nozzle. By designing the connection between the shaft and the nozzle as detachable, modularity and independence of the shaft and nozzle are achieved. This design allows for individual replacement, repair, or cleaning of the shaft or nozzle without disassembling the housing or affecting other components, significantly improving product maintainability and lifespan. Simultaneously, the detachable connection facilitates production assembly, allowing the shaft and nozzle to be processed, inspected, and assembled as two independent components, helping to improve production efficiency and reduce overall scrap costs due to defects in a single component.

[0019] In some embodiments, the nozzle head is provided with a first snap-fit ​​portion, and one end of the shaft is provided with a second snap-fit ​​portion. The shaft is snapped into the nozzle head via the first snap-fit ​​portion and the second snap-fit ​​portion for transmission connection. By providing a first snap-fit ​​portion on the nozzle head and a second snap-fit ​​portion at one end of the shaft, and by having the shaft be snapped into the nozzle head via the first snap-fit ​​portion and the second snap-fit ​​portion for transmission connection, a quick and reliable detachable connection between the shaft and the nozzle head is achieved. This snap-fit ​​structure not only facilitates the individual assembly and disassembly of the nozzle head or the shaft during assembly and maintenance, but also effectively transmits torque to ensure that the shaft drives the nozzle head to rotate synchronously, significantly improving the modularity and maintainability of the product.

[0020] In some embodiments, the housing has a rotating hole on the side away from the adjusting member. The shaft is rotatably inserted through the rotating hole, and the outer contour of the cross-section of the end of the shaft extending into the housing is larger than the inner contour of the cross-section of the rotating hole to limit the axial movement of the shaft and the nozzle connected to the shaft in the rotating hole. The rotating hole on the housing provides precise rotational guidance and support for the shaft, ensuring the stability and coaxiality of the shaft's rotation. The outer contour of the cross-section of the end of the shaft extending into the housing is larger than the inner contour of the cross-section of the rotating hole, forming an effective axial limiting structure. This structure utilizes the dimensional difference between the shaft's geometry and the rotating hole to mechanically block the shaft and the nozzle connected to the shaft in the axial direction, thereby preventing accidental movement or detachment of the shaft and nozzle along the axial direction of the rotating hole during operation or when impacted by water flow. This ensures the nozzle's axial position is fixed within the housing, thus guaranteeing the reliability of the water pattern switching function and the stability of the seal. This limiting method has a simple structure, requires no additional fastening parts, is easy to assemble, and has high reliability.

[0021] In some embodiments, the nozzle has a water passage cavity communicating with the water supply pipe and a movable component movably disposed within the water passage cavity; in the first position, the first nozzle faces upward and is aligned with the water outlet and communicates with the water passage cavity, the second nozzle faces downward, and the movable component can move under gravity to the connection point between the second nozzle and the water passage cavity and block the second nozzle; in the second position, the second nozzle faces upward and is aligned with the water outlet and communicates with the water passage cavity, the first nozzle faces downward, and the movable component can move under gravity to the connection point between the first nozzle and the water passage cavity and block the first nozzle. When the nozzle is in the first position, the first nozzle faces upward, aligns with the water outlet, and is connected to the water passage chamber. The second nozzle faces downward. Under gravity, the movable part moves to the connection between the second nozzle and the water passage chamber and blocks the second nozzle, thus allowing water to exit through the first nozzle. When the nozzle is rotated to the second position, the second nozzle faces upward, aligns with the water outlet, and is connected to the water passage chamber. The first nozzle faces downward. Under gravity, the movable part moves to the connection between the first nozzle and the water passage chamber and blocks the first nozzle, thus allowing water to exit through the second nozzle. In this way, multiple water types can be switched using only one water supply pipe and the gravity blocking of the movable part. This overcomes the structural complexity of traditional solutions that require multiple independent water supply pipes corresponding to different nozzles, effectively reducing the structural complexity and number of parts of the device, lowering the manufacturing difficulty, improving manufacturing efficiency and product yield, and reducing manufacturing costs. Meanwhile, since only a single water supply pipe is installed, the pipe is thoroughly flushed by the water flow every time water is discharged, avoiding the problem of water accumulation and bacterial growth in the idle pipes of traditional multi-pipe structures, which significantly improves the hygiene performance and safety of the device.

[0022] In some embodiments, the manual water pattern switching device further includes a first sealing ring and a second sealing ring located within the water passage chamber. The first sealing ring is disposed around the periphery of the first nozzle, and the second sealing ring is disposed around the periphery of the second nozzle. In the first position, the movable member seals against the second sealing ring; in the second position, the movable member seals against the first sealing ring. By providing a first sealing ring around the periphery of the first nozzle and a second sealing ring around the periphery of the second nozzle, the movable member can seal against the second sealing ring when the nozzle is in the first position, and seal against the first sealing ring when the nozzle is in the second position. This effectively enhances the sealing performance of the downward-facing nozzle in the non-working state, preventing water leakage from the non-working nozzle, ensuring the accuracy of water pattern switching and water output effect, and improving the reliability and overall performance of the device.

[0023] In some embodiments, the movable element is a ball bearing. By specifically setting the movable element as a ball bearing, the spherical surface of the ball bearing can form a more uniform and tighter line or surface contact seal with the first or second sealing ring. This allows for more reliable sealing when the ball bearing rolls to the corresponding nozzle connection under gravity. Furthermore, the smooth movement and sensitive response of the ball bearing within the water passage cavity further enhance the smoothness of water pattern switching and the stability of the sealing effect.

[0024] In some embodiments, the movable component is a steel ball. By specifically setting the movable component as a steel ball, such as a stainless steel ball, the high density of the steel ball allows it to move more quickly and stably to the connection point of the nozzle to be sealed under the action of gravity. At the same time, the spherical surface of the steel ball can form a reliable seal when it contacts the first or second sealing ring. Its excellent hardness and corrosion resistance ensure the sealing durability and service life of the device under long-term water flow erosion, further enhancing the reliability and overall performance of the manual water pattern switching device.

[0025] In some embodiments, the nozzle can also be rotated relative to the housing to a standby position. In the standby position, the outlets of the first and second nozzles are both facing the inner surface of the housing. The movable part can move under gravity between the first and second nozzles without blocking the first and second nozzles. The first and second nozzles are both in communication with the water passage cavity. By limiting the nozzle to rotate relative to the housing to a standby position, and ensuring that the outlets of both the first and second spray holes face the inner surface of the housing in this standby position, while the movable part moves under gravity between the first and second spray holes without blocking them, the first and second spray holes are connected to the water passage cavity. This allows the first and second spray holes to spray water towards the inner surface of the housing in the standby state, using the water flow to clean the inner surface of the housing and the first and second spray holes themselves. Since the water flow is directly sprayed onto the inner surface of the housing rather than the outside, water splashing during the cleaning process is avoided. Furthermore, a drain outlet is provided at the bottom of the housing, allowing water to drain out, thus achieving a self-cleaning function inside the device. Meanwhile, the movable component naturally falls between the first and second spray holes under the action of gravity without blocking either spray hole, ensuring that the water path remains unobstructed in standby mode, preparing for the next rapid switch of water output mode, and eliminating the risk of starting water pattern errors or jamming that may occur if the movable component stays at a certain spray hole; the entire setup ensures that the manual water pattern switching device has a defined and optimized internal state when not in use, improving the reliability and service life of the device.

[0026] In some embodiments, in the standby position, the water passage cavity is at least partially lower than the first and second spray holes in the direction of gravity, and the movable member remains at the lowest point of the water passage cavity under the influence of gravity. By further defining that in the standby position, the water passage cavity is at least partially lower than the first and second spray holes in the direction of gravity, and the movable member remains at the lowest point of the water passage cavity under the influence of gravity, gravity ensures that the movable member can be stably and reliably positioned at the lowest point of the water passage cavity. This position allows the movable member to be naturally positioned between the first and second spray holes and away from their outlets, completely avoiding the risk of the movable member blocking the first or second spray hole due to accidental displacement in the standby or non-water-flowing state.

[0027] This application also provides a spray gun, which includes a barrel and a manual water pattern switching device as described in any of the above embodiments, wherein the manual water pattern switching device is disposed at the end of the barrel.

[0028] This application also provides a smart toilet seat, which includes a core base for mounting onto a toilet seat and a spray gun as described in any of the above embodiments, the spray gun being disposed on the core base.

[0029] This application also provides a smart toilet, which includes a toilet seat and a smart toilet lid as described in any of the above embodiments, wherein the smart toilet lid is disposed on the toilet seat.

[0030] Since the spray gun, smart toilet seat, and smart toilet mentioned above include the manual water pattern switching device described in any of the above embodiments, the spray gun, smart toilet seat, and smart toilet also have at least the following beneficial effects: the smart toilet, by placing the smart toilet seat as described in any of the above embodiments on the toilet seat, possesses all the technical effects of the manual water pattern switching device of the spray gun. Specifically, the smart toilet can achieve automatic and precise switching of water patterns for multiple cleaning modes through the spray gun inside the smart toilet seat, providing users with a diverse cleaning experience.

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, this application provides a manual water pattern switching device 26, which can be installed on a spray gun 22 or other similar cleaning equipment. The manual water pattern switching device 26 includes a housing 100, a nozzle 200, and an adjusting member 300. The housing 100 has a water outlet 110 at its top and is used to connect to the end of the spray gun 22. The nozzle 200 is disposed inside the housing 100 and has a first spray hole 210 and a second spray hole 220. The adjusting member 300 is rotatably inserted through the housing 100, with one end connected to the nozzle 200 and the other end exposed outside the housing 100 for operation, driving the nozzle 200 to rotate relative to the housing 100 to a first position and a second position. Figure 4 and Figure 5 As shown, in the first position, the first nozzle 210 is aligned with the water outlet 110; in the second position, the second nozzle 220 is aligned with the water outlet 110.

[0044] The aforementioned manual water type switching device 26 can achieve at least the following beneficial effects:

[0045] The manual water type switching device 26 of this application is connected to the end of the spray gun 22 via the housing 100 and is operated using the adjusting member 300 exposed outside the housing 100, which drives the nozzle 200 to rotate relative to the housing 100 to a first position or a second position, such as... Figure 4 and Figure 5 As shown, when the nozzle 200 is in the first position, the first nozzle 210 is aligned with the outlet 110 to spray the first water pattern. When the nozzle 200 is in the second position, the second nozzle 220 is aligned with the outlet 110 to spray the second water pattern. Thus, switching between the two different water patterns can be achieved simply by manually rotating the adjusting component 300. This structure has wide adaptability. It can be used as an independent manual switching solution on a simple spray gun 22 without a motor 24 to reduce overall cost and complexity. It eliminates the need for the drive motor 24, control circuit, and complex transmission mechanism required by traditional electric switching, greatly simplifying the overall structure of the device and reducing manufacturing costs and energy consumption. It can also be integrated as a backup or auxiliary switching module on a spray gun 22 with a motor 24. When the motor 24 drive system is working normally, it provides an intuitive and convenient quick switching option. When the motor 24 and other electronic drive components fail, it serves as a reliable emergency manual switching guarantee, thereby ensuring that the spray gun 22 can reliably switch water patterns under various working conditions and configurations. This significantly improves the product's functional redundancy, environmental adaptability, and user satisfaction.

[0046] like Figure 2As shown, in some embodiments, the housing 100 has an adjustment hole 120 on the side away from the spray gun 22, the adjustment member 300 is rotatably inserted through the adjustment hole 120, and the end of the adjustment member 300 away from the nozzle 200 is provided with an operating protrusion 310, the operating protrusion 310 is used for operation to drive the rotation of the adjustment member 300 and the nozzle 200. By setting an independent adjustment hole 120, a precise and stable rotational support is provided for the adjustment component 300, ensuring the accuracy of axial positioning and smoothness of rotation of the adjustment component 300 during manual operation, and effectively preventing the adjustment component 300 from swaying or jamming due to uneven force. At the same time, the operating protrusion 310 set at the end of the adjustment component 300 significantly increases the working area and force application fulcrum of the hand or tool, allowing the operator to apply rotational torque more effortlessly and precisely, thereby reliably driving the nozzle 200 in the housing 100 to rotate to the predetermined position through the adjustment component 300. This achieves the convenience, effortlessness and high reliability of water type switching operation, and further optimizes the human-machine interaction experience.

[0047] like Figure 2 As shown, in some embodiments, the operating protrusion 310 has two opposing operating surfaces 311 along the radial direction of the adjustment hole 120. The two opposing operating surfaces 311 provide a clear and stable gripping or force application position for the fingers of the hand, allowing the operator to apply rotational torque to the operating protrusion 310 more evenly and effectively by pinching or applying force in opposite directions, making operation more convenient.

[0048] like Figure 2 As shown, in some embodiments, a limiting rib is formed on the outer peripheral surface of the nozzle 200 near the adjusting hole 120. The limiting rib is engaged with the periphery of the adjusting hole 120 to restrict the axial movement of the nozzle 200 in the adjusting hole 120. By directly setting the limiting rib on the nozzle 200 and using it to engage with the periphery structure of the adjusting hole 120 on the housing 100, a simple, reliable, and compact mechanical limit is provided for the nozzle 200 in the axial direction without adding additional parts. This effectively prevents the nozzle 200 from rotating under the action of the adjusting member 300 or from axially shifting or accidentally dislodging under water pressure impact. It ensures the axial position stability of the nozzle 200 within the housing 100, thereby guaranteeing the long-term accuracy and consistency of the alignment between the first spray hole 210 and the second spray hole 220 and the outlet 110 of the housing 100, and improving the structural stability and operational reliability of the entire manual water pattern switching device 26.

[0049] like Figure 2As shown, in some embodiments, the adjusting member 300 is integrally formed with the nozzle 200. By integrating the adjusting member 300 and the nozzle 200 into an inseparable integral part, the possible assembly gaps, loose connections, or relative rotational errors between the two are completely eliminated. This ensures that the rotational torque applied by the operating protrusion 310 can be directly, losslessly, and completely synchronously transmitted to the nozzle 200, thereby greatly improving the response speed, control accuracy, and transmission reliability of the water pattern switching action. At the same time, the integrally formed structure reduces the number of parts, simplifies the assembly process, reduces the defect rate caused by the accumulation of tolerances in the fit of multiple parts, and enhances the overall structural strength and durability of the moving component in long-term use, thus optimizing the reliability and cost-effectiveness of the product from both manufacturing and performance perspectives.

[0050] In some embodiments, the adjusting component 300 is detachably connected to the nozzle 200. By employing detachable connection methods, such as threaded connections, snap-fit ​​connections, or keyway engagements, a modular design for the adjusting component 300 and the nozzle 200 is achieved. This structure allows for independent replacement or repair of either the adjusting component 300 or the nozzle 200 without replacing the entire assembly, thereby improving product maintainability and lifespan, and reducing long-term operating costs.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the manual water pattern switching device 26 further includes a rotating shaft that is rotatably disposed in the housing 100. The rotating shaft is located on the side of the nozzle 200 away from the adjusting member 300. A water supply pipe is formed inside the rotating shaft. The rotating shaft is connected to and communicates with the nozzle 200 to supply water to the nozzle 200. The adjusting member 300 is coaxially disposed with the rotating shaft. By introducing a rotating shaft with an internally formed water supply pipe as an independent water supply and rotation support component, the water supply function of the nozzle 200 and the operation function of the adjustment component 300 are structurally separated and integrated. The rotating shaft is rotatably installed in the housing 100, providing a stable and reliable rotation support point on the other side of the nozzle 200 for the entire device, optimizing the stress structure and enhancing the stability during rotation. The water supply pipe formed inside the rotating shaft allows water from the water source to be stably and directly delivered to the nozzle 200 through the internal structure of the rotating shaft itself, realizing the complete unification and internalization of the water supply path and the rotation axis, avoiding the risks of entanglement, wear, space occupation, or leakage that may occur when external water pipes are connected at the rotating parts, and simplifying the layout of external pipelines.

[0052] like Figure 3As shown, in some embodiments, one end of the shaft 400 extending into the housing 100 is detachably connected to the nozzle 200. By designing the connection between the shaft 400 and the nozzle 200 as detachable, the shaft 400 and nozzle 200 are modularized and independent. This design allows for the individual replacement, repair, or cleaning of the shaft 400 or nozzle 200 without disassembling the housing 100 or affecting other components, thereby significantly improving product maintainability and service life. Simultaneously, the detachable connection also facilitates production assembly, allowing the shaft 400 and nozzle 200 to be processed, inspected, and assembled as two independent components, helping to improve production efficiency and reduce overall scrap costs due to defects in a single component.

[0053] like Figure 3 As shown, in some embodiments, the nozzle 200 is provided with a first snap-fit ​​portion 261, and one end of the shaft 400 is provided with a second snap-fit ​​portion 420. The shaft 400 is snapped into the nozzle 200 via the first snap-fit ​​portion 261 and the second snap-fit ​​portion 420 for transmission connection. By setting the first snap-fit ​​portion 261 on the nozzle 200 and the second snap-fit ​​portion 420 at one end of the shaft 400, and making the shaft 400 snap-fit ​​into the nozzle 200 via the first snap-fit ​​portion 261 and the second snap-fit ​​portion 420 for transmission connection, a quick and reliable detachable connection between the shaft 400 and the nozzle 200 is achieved. This snap-fit ​​structure not only facilitates the individual assembly and disassembly of the nozzle 200 or the shaft 400 during assembly and maintenance, but also effectively transmits torque to ensure that the shaft 400 drives the nozzle 200 to rotate synchronously, significantly improving the modularity and maintainability of the product.

[0054] like Figure 2As shown, in some embodiments, the housing 100 has a rotating hole 130 on the side away from the adjusting member 300, and the shaft 400 is rotatably inserted through the rotating hole 130. The outer contour of the cross-section of the end of the shaft 400 extending into the housing 100 is larger than the inner contour of the cross-section of the rotating hole 130 to limit the axial movement of the shaft 400 and the nozzle 200 connected to the shaft 400 in the rotating hole 130. A rotating hole 130 on the housing 100 provides precise rotational guidance and support for the shaft 400, ensuring the stability and coaxiality of the shaft 400's rotation. The outer contour of the cross-section of the end of the shaft 400 extending into the housing 100 is larger than the inner contour of the cross-section of the rotating hole 130, forming an effective axial limiting structure. This structure utilizes the dimensional difference between the geometry of the shaft 400 and the rotating hole 130 to mechanically block the shaft 400 and the nozzle 200 connected through the shaft 400 in the axial direction. This prevents the shaft 400 and the nozzle 200 from accidentally shifting or falling off along the axial direction of the rotating hole 130 during operation or when impacted by water flow, ensuring the fixed axial position of the nozzle 200 within the housing 100, thereby guaranteeing the reliability of the water pattern switching function and the stability of the seal. This limiting method has a simple structure, requires no additional fastening parts, is easy to assemble, and has high reliability.

[0055] like Figure 2 and Figure 5 As shown, in some embodiments, the nozzle 200 is provided with a water passage cavity 230 communicating with the water supply pipe 410 and a movable component 240 movably disposed within the water passage cavity 230; for example Figure 5As shown, in the first position, the first nozzle 210 faces upward and is aligned with the outlet 110 and communicates with the water passage chamber 230, while the second nozzle 220 faces downward. The movable component 240 can move under gravity to the connection point between the second nozzle 220 and the water passage chamber 230 and block the second nozzle 220. In the second position, the second nozzle 220 faces upward and is aligned with the outlet 110 and communicates with the water passage chamber 230, while the first nozzle 210 faces downward. The movable component 240 can move under gravity to the connection point between the first nozzle 210 and the water passage chamber 230 and block the first nozzle 210. When the nozzle 200 is in the first position, the first nozzle 210 faces upward, aligns with the outlet 110, and communicates with the water passage chamber 230. The second nozzle 220 faces downward. The movable part 240 moves under gravity to the connection between the second nozzle 220 and the water passage chamber 230 and blocks the second nozzle 220, thereby allowing water to exit through the first nozzle 210. When the nozzle 200 rotates to the second position, the second nozzle 220 faces upward, aligns with the outlet 110, and communicates with the water passage chamber 230. The first nozzle 210 faces downward, and the movable part 240 moves under gravity to the connection between the second nozzle 220 and the water passage chamber 230 and blocks the second nozzle 220, thus allowing water to exit through the first nozzle 210. Under the influence of gravity, the device moves to the connection point between the first nozzle 210 and the water passage chamber 230 and blocks the first nozzle 210, thereby allowing water to exit through the second nozzle 220. Thus, multiple water types can be switched using only a single water supply pipe 410 and the gravity-sealed movable part 240. This overcomes the structural complexity of traditional solutions that require multiple independent water supply pipes corresponding to different nozzles, effectively reducing the structural complexity and number of components, lowering manufacturing difficulty, improving manufacturing efficiency and product yield, and reducing manufacturing costs. Furthermore, because only a single water supply pipe 410 is used, this pipe is thoroughly flushed by the water flow each time water is discharged, avoiding the problem of water accumulation and bacterial growth in idle pipes in traditional multi-pipe structures, significantly improving the hygiene performance and safety of the device.

[0056] like Figure 5As shown, in some embodiments, the manual water pattern switching device 26 further includes a first sealing ring 510 and a second sealing ring 520 located within the water passage chamber 230. The first sealing ring 510 is disposed around the periphery of the first spray hole 210, and the second sealing ring 520 is disposed around the periphery of the second spray hole 220. In the first position, the movable member 240 seals against the second sealing ring 520; in the second position, the movable member 240 seals against the first sealing ring 510. By setting a first sealing ring 510 around the first nozzle 210 and a second sealing ring 520 around the second nozzle 220, the movable part 240 can seal against the second sealing ring 520 when the nozzle 200 is in the first position, and can seal against the first sealing ring 510 when the nozzle 200 is in the second position. This effectively enhances the sealing performance of the downward nozzle in the non-working state by utilizing the sealing contact between the movable part 240 and the corresponding sealing ring, preventing water leakage from the non-working nozzle, ensuring the accuracy of water pattern switching and water output effect, and improving the reliability and overall performance of the device.

[0057] like Figure 5 As shown, in some embodiments, the movable element 240 is a ball bearing. By specifically setting the movable element 240 as a ball bearing, the spherical surface of the ball bearing can form a more uniform and tighter line contact or surface contact seal with the first sealing ring 510 or the second sealing ring 520. This allows for more reliable sealing when the ball bearing rolls to the corresponding nozzle connection under gravity. At the same time, the smooth movement and sensitive response of the ball bearing within the water passage cavity 230 further improve the smoothness of water pattern switching and the stability of the sealing effect.

[0058] In some embodiments, the movable element 240 is a steel ball. By specifically setting the movable element 240 as a steel ball, such as a stainless steel ball, the high density of the steel ball allows it to move more quickly and stably to the connection point of the nozzle to be sealed under the action of gravity. At the same time, the spherical surface of the steel ball can form a reliable seal when it comes into contact with the first sealing ring 510 or the second sealing ring 520. Its excellent hardness and corrosion resistance ensure the sealing durability and service life of the device under long-term water flow erosion, further enhancing the reliability and overall performance of the manual water pattern switching device 26.

[0059] like Figure 6As shown, in some embodiments, the nozzle 200 can also rotate relative to the housing 100 to a standby position. In the standby position, the outlets of the first nozzle 210 and the second nozzle 220 are both facing the inner surface of the housing 100. The movable member 240 can move under gravity between the first nozzle 210 and the second nozzle 220 without blocking the first nozzle 210 and the second nozzle 220. The first nozzle 210 and the second nozzle 220 are both connected to the water passage chamber 230. By limiting the nozzle 200 to rotate relative to the housing 100 to a standby position, and in this standby position, ensuring that the outlets of the first nozzle 210 and the second nozzle 220 both face the inner surface of the housing 100, while the movable member 240 moves under gravity between the first nozzle 210 and the second nozzle 220 without blocking them, both nozzles 210 and 220 are connected to the water passage chamber 230, thereby achieving... In standby mode, both the first nozzle 210 and the second nozzle 220 can spray water towards the inner surface of the housing 100. The water flow cleans the inner surface of the housing 100 and the nozzles themselves. Since the water is sprayed directly onto the inner surface of the housing 100 rather than the outside, splashing during cleaning is avoided. Furthermore, a drain outlet 140 is located at the bottom of the housing 100, allowing water to drain out, thus achieving a self-cleaning function within the device. Simultaneously, the movable component 240 naturally settles between the first nozzle 210 and the second nozzle 220 under gravity without blocking either nozzle, ensuring the water path remains unobstructed in standby mode. This prepares the device for the next rapid switching of water output modes and eliminates the risk of incorrect water pattern startup or jamming caused by the movable component 240 remaining at a particular nozzle. This entire design ensures that the manual water pattern switching device 26 has a defined and optimized internal state during non-use periods, improving the device's reliability and lifespan.

[0060] like Figure 6As shown, in some embodiments, in the standby position, the water passage cavity 230 is at least partially lower than the first nozzle 210 and the second nozzle 220 in the direction of gravity G, and the movable member 240 remains at the lowest point of the water passage cavity 230 under the influence of gravity. By further defining that in the standby position, the water passage cavity 230 is at least partially lower than the first nozzle 210 and the second nozzle 220 in the direction of gravity G, and the movable member 240 remains at the lowest point of the water passage cavity 230 under the influence of gravity, gravity ensures that the movable member 240 can be stably and reliably positioned at the lowest point of the water passage cavity 230. This position allows the movable member 240 to be naturally positioned between the first nozzle 210 and the second nozzle 220 and away from the outlets of the first nozzle 210 and the second nozzle 220, completely avoiding the risk that the movable member 240 may block the first nozzle 210 or the second nozzle 220 due to accidental displacement in the standby state or non-water-flowing state.
