[0023] Reference Figures 1 to 4Water outlet device, including: The water outlet unit includes a water outlet component 140, which forms a first water outlet channel 250 and a second water outlet channel 260. The switching unit includes a first blocking block 170, a second blocking block 180 and a driving block. The driving block is connected to the first blocking block 170 and the second blocking block 180 in a transmission manner. The first blocking block 170 is set to correspond to the first water outlet channel 250 and the second blocking block 180 is set to correspond to the second water outlet channel 260. When the drive block switches to the first position, the drive block causes the first block 170 to separate from the first water outlet channel 250 so that the first water outlet channel 250 can be opened, and drives the second block 180 to seal and abut against the second water outlet channel 260 to block the second water outlet channel 260. When the drive block switches to the second position, the drive block causes the first block 170 to seal against the first water outlet channel 250 to block the first water outlet channel 250, and drives the second block 180 to separate from the second water outlet channel 260 so that the second water outlet channel 260 can be opened.

[0024] The drive block, connected to the first block 170 and the second block 180, enables the coordinated switching of the two water outlet channels. When the drive block switches to the first position, the first water outlet channel 250 is open while the second water outlet channel 260 is blocked; when switched to the second position, the first water outlet channel 250 is blocked while the second water outlet channel 260 is open. This structure achieves an interlocking switching mechanism of "one open, one closed," effectively preventing the two channels from being open or closed simultaneously, ensuring the accuracy and stability of water flow switching. The drive block can synchronously control the opening and closing of the two block blocks with a single operation, without the need for additional rotation or step-by-step operation. The user only needs to apply a single driving force to complete the mode switching, making the operation simple, the response sensitive, and improving the ease of use. The first block 170 and the second block 180 respectively seal the first water outlet channel 250 and the second water outlet channel 260, achieving reliable sealing of the channels through sealing contact, effectively preventing water leakage or cross-contamination, and improving the sealing reliability and service life of the device.

[0025] The drive block is provided with a first guide slope 190 and a second guide slope 200. The first guide slope 190 is set to correspond to the first block 170, and the second guide slope 200 is set to correspond to the second block 180. The first guide slope 190 and the second guide slope 200 are set opposite to each other.

[0026] In this water outlet device, the drive block is provided with a first guide slope 190 and a second guide slope 200, which are arranged opposite to each other. When the drive block moves axially or laterally, its first guide slope 190 contacts the first block 170 and generates a pushing force. The inclination angle of the slope converts the movement of the drive block into a vertical or lateral component force on the first block 170, thereby pushing the first block 170 closer to or away from the first water outlet channel 250, realizing the opening or closing of the channel. At the same time, the second guide slope 200 on the drive block acts synchronously on the second block 180. Since the two guide slopes are arranged opposite to each other, when the drive block moves in one direction, the first guide slope 190 applies a pushing force to the first block 170 to seal the water outlet channel, while the second guide slope 200 applies a reverse pulling or releasing force to the second block 180, causing it to break the seal and thus opening the second water outlet channel 260; and vice versa. Through this inclined plane transmission structure, a single movement of the drive block can realize the linkage switching of the two blockages, completing the conversion between the two water output modes.

[0027] By setting up a first guide ramp 190 and a second guide ramp 200 arranged opposite to each other, and utilizing the principle of ramp transmission, a single linear movement of the drive block can synchronously control the opening and closing of the first block 170 and the second block 180. This eliminates the need for additional control mechanisms or complex operations, significantly simplifying the water outlet mode switching process. The guide ramps are directly integrated into the drive block, resulting in a high degree of structural integration. This eliminates the need for additional connecting rods or gear transmission components, reducing the overall size while improving force transmission efficiency, ensuring sensitive and rapid switching action.

[0028] The first block 170 and the second block 180 are respectively provided with annular guide portions 210 at their ends facing the drive block, and the annular guide portions 210 are in contact with the first guide slope 190 and the second guide slope 200 respectively.

[0029] During the switching process of the water outlet device, the first block 170 and the second block 180 are respectively provided with annular guide portions 210 at the ends facing the drive block. When the drive block moves, the first guide slope 190 on it keeps in contact with the annular guide portion 210 of the first block 170, and the second guide slope 200 is correspondingly attached to the annular guide portion 210 of the second block 180. As the drive block is displaced, the guide slope slides along the surface of the annular guide portion 210, decomposing the movement direction of the drive block into a component force perpendicular to the movement direction of the block, thereby pushing the first block 170 or the second block 180 to move along its axial direction.

[0030] Since the annular guide part 210 is arranged around the end of the block, it can make uniform contact with the guide slope in the entire circumference, ensuring that the force distribution is symmetrical during the movement of the drive block, avoiding the block from tilting or getting stuck during movement, and ensuring that it smoothly approaches or disengages from the corresponding water outlet channel, so as to realize the opening or closing of the channel.

[0031] The annular guide section 210 forms continuous circumferential contact with the guide ramp, ensuring that the driving force is evenly transmitted along the circumference. This effectively prevents the first block 170 and the second block 180 from becoming eccentric, tilting, or jamming during movement, significantly improving the smoothness of the movement and the guiding accuracy. The annular structure has good load-bearing capacity and contact stability. Compared to point or line contact, it can withstand greater lateral forces and friction, extending the service life of the mating surfaces and improving the durability of the switching mechanism.

[0032] The switching unit also includes a first elastic reset member 220 and a second elastic reset member 230. The first elastic reset member 220 acts on the first block 170, and the second elastic reset member 230 acts on the second block 180. The first elastic reset member 220 drives the first block 170 to move away from the first water outlet channel 250, and the second elastic reset member 230 drives the second block 180 to move away from the second water outlet channel 260.

[0033] During the switching operation of the water outlet device, when the drive block pushes the first block 170 toward the first water outlet channel 250 to achieve sealing, the first elastic reset member 220 is compressed or deformed, storing elastic potential energy; at the same time, after the drive block releases its action, the second elastic reset member 230 pushes the second block 180 toward a direction away from the second water outlet channel 260, ensuring that the second water outlet channel 260 remains open or ready in the non-working state.

[0034] Conversely, when the drive block switches to another position to block the second water outlet channel 260 and open the first water outlet channel 250, the second elastic reset member 230 is compressed, while the first elastic reset member 220 releases its stored energy and actively drives the first block 170 to retract and disengage from the sealed position of the first water outlet channel 250.

[0035] After the driving force of the drive block is removed, the first elastic reset member 220 and the second elastic reset member 230 respectively use their own elastic restoring force to automatically reset the corresponding block to the initial position, thereby preparing for the next switching action and realizing automatic rebound and state reset during the switching process.

[0036] By setting the first elastic reset element 220 and the second elastic reset element 230, the first block 170 and the second block 180 can be automatically pushed away from the water outlet channel after the drive block is retracted. This prevents the block from remaining in the sealing position due to friction or residual water pressure, ensuring reliable opening of the water outlet channel and improving the response speed and reliability of the switching mechanism. The elastic reset element provides appropriate rebound force during the switching process, allowing the user to obtain clear force feedback when operating the button 130 or the drive structure, improving the comfort and intuitiveness of operation, especially suitable for applications with frequent switching.

[0037] The outer walls of the first block 170 and the second block 180 are provided with guide grooves, and the inner wall of the water outlet 140 is provided with guide strips. The guide grooves and guide strips are adapted to each other.

[0038] During mode switching of the water outlet device, the first block 170 and the second block 180 need to reciprocate along a predetermined path to open and close the first water outlet channel 250 and the second water outlet channel 260. To ensure the accuracy of the block movement direction, guide grooves are provided on the outer walls of the first block 170 and the second block 180, while guide strips are correspondingly provided on the inner wall of the water outlet component 140. The guide strips are embedded in the guide grooves and slide along their length. When the drive block pushes the first block 170 or the second block 180 to move, the guide strips slide synchronously in the guide grooves, restricting the block's freedom in the radial or rotational direction, forcing it to move only along the axial direction or a preset straight trajectory. This guide engagement structure works continuously throughout the switching stroke, effectively preventing the block from shifting, tilting, or rotating during movement, ensuring that its end can be accurately aligned with the water outlet channel, achieving reliable sealing or opening.

[0039] The guiding structure forms a stable connection between the plug and the outlet component 140, effectively resisting the impact of water flow or shaking caused by external operating forces, preventing displacement of the plug during operation, and ensuring the durability of the sealing performance. The cooperation between the guide groove and the guide strip has an anti-rotation function, which can limit the circumferential rotation of the plug during movement, ensuring that the sealing head and the outlet channel always maintain correct alignment, and avoiding wear or leakage of the sealing surface due to angular deviation.

[0040] The end of the first block 170 is provided with a first semi-circular sealing head that mates with the first water outlet channel 250, and the end of the second block 180 is provided with a second semi-circular sealing head that mates with the second water outlet channel 260. Both the first and second semi-circular sealing heads are provided with sealing rings.

[0041] When the water outlet device switches modes, the first block 170 and the second block 180 move closer to or away from the corresponding first water outlet channel 250 and second water outlet channel 260 under the action of the drive block. The first semi-circular sealing head at the end of the first block 170 matches the outlet profile of the first water outlet channel 250, and the second semi-circular sealing head at the end of the second block 180 matches the outlet of the second water outlet channel 260.

[0042] When a block is pushed to the sealing position, its semi-circular sealing head comes into contact with and presses against the end face of the water outlet channel. At the same time, the sealing ring on the sealing head undergoes elastic deformation, filling the microscopic gaps between the sealing surfaces to form a reliable sealing interface, effectively blocking water flow. When the block retracts, the sealing head disengages from the water outlet channel, and the sealing ring returns to its original shape, preparing for the next sealing action.

[0043] Because of its excellent centering and contact adaptability, the semi-circular structure can achieve uniform stress distribution through curved surface contact even with minor deviations during assembly or movement, thus improving the stability and durability of the seal.

[0044] The first and second semi-circular sealing heads are shaped to fit the end contours of the corresponding water outlet channels, enabling surface or line contact sealing. Compared to planar or irregularly shaped structures, they offer better fit, significantly improving sealing reliability and preventing leakage or seepage. The semi-circular structure has self-centering properties; as the plug approaches the sealing position, it can automatically adjust its alignment through curved surface sliding, reducing the risk of seal failure due to assembly errors or movement misalignment and improving the mechanism's fault tolerance.

[0045] The water outlet unit also includes a water inlet 150 and a telescopic water supply pipe. One end of the water inlet 150 is detachably connected to the water inlet end of the water outlet 140 via a double snap-fit ​​structure 160, and the other end is connected to the telescopic water supply pipe.

[0046] During the use of the water outlet device, external water is introduced through a telescopic water supply pipe. One end of the telescopic water supply pipe is connected to the water inlet 150, and the other end leads to the water source interface. One end of the water inlet 150 has a connection structure that matches the water inlet end of the water outlet 140. A double-clamp structure 160 enables quick connection or disconnection with the water outlet 140. When installation is required, the water inlet 150 is aligned with the water inlet end of the water outlet 140 and inserted. The double-clamp structure 160 automatically locks in place, forming a secure connection and ensuring the sealing of the water flow channel. When disassembly is required (e.g., for cleaning, maintenance, or replacement of parts), simply press the clamp release mechanism to separate the water inlet 150 from the water outlet 140. The operation is simple and quick. The telescopic water supply pipe has a stretchable and retractable structure, allowing for free adjustment of its length according to usage needs. When not in use, it retracts to a minimum size, reducing space occupation.

[0047] The dual-clamp structure 160 enables a detachable connection between the inlet component 150 and the outlet component 140, allowing for tool-free assembly and disassembly. This significantly improves installation efficiency and maintenance convenience, making it particularly suitable for bathroom applications requiring frequent cleaning or replacement. The dual-clamp design provides two-point symmetrical locking, offering higher connection strength and vibration resistance compared to single-clamp or threaded connections. This effectively prevents loosening or detachment due to water pressure fluctuations or external pulling, enhancing safety during use.

[0048] The water outlet unit also includes a magnetic base 100, which is fixed to the external mounting surface. The magnetic base 100 has a through hole through which the telescopic water supply pipe passes. The end of the telescopic water supply pipe is made of magnetic material.

[0049] During the use of the water outlet device, the magnetic base 100 is installed on the wall, shower rod, or faucet body by adhesive, screws, or other fixing methods. The magnetic base 100 has a through hole through which the telescopic water supply pipe passes axially to guide and position the water supply path.

[0050] When the user finishes using the device and places it near the magnetic base 100, the end of the telescopic water supply pipe, made of magnetic material, attracts the user with a magnetic force, automatically adsorbing and securing the device to the base. The magnetic force keeps the device in a preset position, preventing it from swinging or slipping.

[0051] When the device is needed again, the user only needs to apply a slight pulling force to overcome the magnetic attraction and easily remove the water outlet. The telescopic water supply pipe will then extend and the water supply will start normally.

[0052] With the magnetic base 100 engaging with the magnetic material end, the water outlet device can be automatically attracted and positioned after use, eliminating the need for precise alignment. This solves the problems of difficult return and cumbersome operation associated with traditional showerheads, significantly improving the user experience. The magnetic connection provides a stable and reliable fixing force, effectively preventing the water outlet device from slipping due to slight contact or water residue, avoiding damage or safety hazards, and is especially suitable for slippery bathroom environments.

[0053] The water outlet component 140 also includes a button 130, which is connected to the drive block. A third reset component is provided between the button 130 and the water outlet component 140, and the third reset component drives the button 130 to reset to the initial position.

[0054] During the use of the water outlet device, the user switches the water outlet mode by pressing the button 130 on the water outlet component 140. The button 130 is connected to the drive block. When the user applies external force to press the button 130, the operating force is directly transmitted to the drive block through the transmission structure, causing it to move in a predetermined direction, thereby triggering the linkage action of the first block 170 and the second block 180, realizing the switching between the first water outlet channel 250 and the second water outlet channel 260.

[0055] During the pressing of button 130, the third reset component (such as a spring, elastic arm, or other elastic element) is compressed or deformed, storing elastic potential energy. When the user releases button 130, the third reset component releases the stored energy, generating a restoring force that pushes button 130 back to its initial position, completing one operation cycle.

[0056] This reset process ensures that button 130 does not remain pressed, preparing for the next switching operation, while providing clear operational feedback and improving the human-computer interaction experience.

[0057] By setting an exposed button 130, users can simply press it to switch water output modes, making the operation intuitive and effortless, without the need for rotating or turning complex mechanisms, significantly improving ease of use. The third reset component provides a reliable reset driving force for the button 130, preventing the button 130 from failing to spring back due to friction or scale buildup, ensuring that the device returns to the standby state after each operation, and improving the repeatability and reliability of the switching action.

[0058] The water outlet unit also includes a first water outlet 110 and a second water outlet 120. The first water outlet 110 is connected to the first water outlet channel 250, and the second water outlet 120 is connected to the second water outlet channel 260. The second water outlet 120 is coaxially sleeved outside the first water outlet 110, and the second water outlet 120 is fixed to the water outlet component 140 by threaded connection.

[0059] When the water outlet device is working, the water flow is conducted through the first water outlet channel 250 or the second water outlet channel 260 according to the switching state. The first water outlet 110 is connected to the first water outlet channel 250 and is used to output the first water flow mode (such as rain shower or gentle flow); the second water outlet 120 is connected to the second water outlet channel 260 and is used to output the second water flow mode (such as massage or jet flow).

[0060] The second water outlet 120 is coaxially sleeved outside the first water outlet 110, and the two share a central axis, forming a concentric arrangement of inner and outer nesting. The second water outlet 120 is screwed into the corresponding internal threaded hole of the water outlet component 140 through a threaded structure on its outer circumference, achieving axial fixation and sealing connection. After tightening, the second water outlet 120 is stably held in the predetermined position and will not loosen due to water flow impact or operational vibration.

[0061] When the switching unit controls the first water outlet channel 250 to be open, water flows out from the first water outlet 110; when the second water outlet channel 260 is open, water flows out from the second water outlet 120. Due to the compact spatial layout and precise positioning of the two water outlets, users can clearly perceive the switching between different modes, and the water flow direction is consistent, resulting in a good user experience.

[0062] By coaxially mounting the second water outlet 120 around the first water outlet 110, the radial space is fully utilized, avoiding the increased volume caused by arranging multiple water outlets side by side. This makes the structure of the water outlet component 140 more compact, suitable for bathroom installation environments with limited space. The concentric design of the water outlets inside and out has a high degree of symmetry and a sense of unity, with a simple and beautiful appearance, enhancing the product's quality and meeting the aesthetic requirements of modern bathroom products.

[0063] Reference Figures 1 to 4 This utility model provides a water outlet device, which is particularly suitable for scenarios such as bathroom shower heads and handheld sprayers that require switching between multiple water outlet modes. The water outlet device has a compact overall structure, is easy to operate, and has a reliable seal. It can quickly switch between two different water outlet modes and has good maintainability and user experience.

[0064] The water outlet device includes a water outlet unit and a switching unit. The water outlet unit includes a water outlet component 140, which internally forms a first water outlet channel 250 and a second water outlet channel 260 for guiding water flow and achieving different water outlet modes. The first water outlet channel 250 is used to output aerated water, and the second water outlet channel 260 is used to output concentrated shower water, but is not limited thereto.

[0065] The water outlet unit also includes a first water outlet 110 and a second water outlet 120. The first water outlet 110 is connected to the first water outlet channel 250 and is located at the center of the front end of the water outlet component 140; the second water outlet 120 is connected to the second water outlet channel 260 and is coaxially sleeved on the outside of the first water outlet 110, forming a concentric structure with inner and outer nesting. This design makes full use of radial space, resulting in a compact and aesthetically pleasing overall layout. The second water outlet 120 is fixed to the water outlet component 140 by a threaded connection, ensuring a secure connection, easy disassembly, and convenient cleaning and replacement later.

[0066] The water outlet unit also includes a water inlet 150 and a telescopic water supply pipe. One end of the water inlet 150 is detachably connected to the water inlet end of the water outlet 140 via a double-clamp structure 160, allowing for quick connection and tool-free installation or disassembly, which is beneficial for daily cleaning; the other end connects to the telescopic water supply pipe to introduce water. The telescopic water supply pipe has good tensile and retraction performance, and its length can be freely adjusted according to usage needs, improving usage flexibility and space adaptability.

[0067] The water outlet unit also includes a magnetic base 100, which is fixed to an external mounting surface such as a wall or shower rod by adhesive or screws. The magnetic base 100 has a through hole through which a telescopic water supply pipe passes and extends to the water source interface. The end of the telescopic water supply pipe is made of magnetic material. When the user places the water outlet device near the magnetic base 100, an attractive force is generated between the magnetic end and the magnetic base 100, achieving automatic repositioning and stable storage. This structure solves the problems of traditional shower heads having difficulty repositioning and requiring precise alignment, achieving convenient "place and suck" operation, improving safety and user experience.

[0068] The switching unit is used to control the opening and closing of the first water outlet channel 250 and the second water outlet channel 260, thereby realizing the switching of the water outlet mode. The switching unit includes a first blocking block 170, a second blocking block 180 and a driving block. The driving block is operatively connected to the first blocking block 170 and the second blocking block 180. The first blocking block 170 is correspondingly disposed at the outlet of the first water outlet channel 250, and the second blocking block 180 is correspondingly disposed at the outlet of the second water outlet channel 260.

[0069] The drive block is provided with a first guide ramp 190 and a second guide ramp 200. The first guide ramp 190 is set corresponding to the first blocking block 170, and the second guide ramp 200 is set corresponding to the second blocking block 180. The first guide ramp 190 and the second guide ramp 200 are arranged opposite to each other. When the drive block moves axially, its guide ramps contact the blocking blocks and generate pushing force, converting the linear motion of the drive block into the opening and closing action of the blocking blocks.

[0070] The first blocking block 170 and the second blocking block 180 are respectively provided with annular guide portions 210 at one end facing the driving block. The annular guide portions 210 slide in contact with the first guide slope 190 and the second guide slope 200. This annular structure achieves uniform force distribution in the circumference, ensuring that the blocking blocks do not deviate or get stuck during movement, thus improving the stability of movement and guiding accuracy.

[0071] The outer walls of the first block 170 and the second block 180 are provided with guide grooves, and the inner wall of the water outlet 140 is provided with a matching guide strip. The guide strip is embedded in the guide groove and slides along it. This guide structure precisely limits the movement path of the block, preventing it from rotating or shifting laterally, and ensuring the accuracy and reliability of the sealing action.

[0072] Regarding the sealing structure, the end of the first blocking block 170 is provided with a first semi-circular sealing head that matches the first water outlet channel 250, and the end of the second blocking block 180 is provided with a second semi-circular sealing head that matches the second water outlet channel 260. Both the first and second semi-circular sealing heads are equipped with sealing rings. This semi-circular structure has good centering and contact adaptability, and can automatically adjust the fitting angle during compression sealing, achieving surface sealing in conjunction with the sealing rings, effectively preventing water leakage or cross-contamination, and improving sealing durability.

[0073] The switching unit also includes a first elastic reset member 220 and a second elastic reset member 230. The first elastic reset member 220 acts on the first block 170, driving the first block 170 to move away from the first water outlet channel 250; the second elastic reset member 230 acts on the second block 180, driving the second block 180 to move away from the second water outlet channel 260. The elastic reset mechanism ensures that the block can automatically retract after the driving block is removed, avoiding stagnation due to friction or water pressure, and improving the switching response speed and reliability.

[0074] The water outlet component 140 is also equipped with a button 130, which is connected to the drive block. The user can move the drive block by pressing the button 130 to switch modes. A third elastic reset component 240 (such as a compression spring) is provided between the button 130 and the water outlet component 140 to automatically reset the button 130 to its initial position after release. This structure provides clear operational feedback, prevents the button 130 from jamming, and ensures that the device returns to standby mode after each operation.
