Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a water outlet device. Background Technology

[0002] Currently, bathroom fixtures such as showerheads typically have multiple water flow modes, such as mouthwash mode, shower water mode, and pressurized water mode. Users can switch between water flow modes using a switch button to enable the showerhead to have different rinsing functions.

[0003] In existing technologies, switching knobs are typically either push-button or rotary knobs. For example, the water outlet device disclosed in patent CN119593483A, entitled "A Water Outlet Component and Device," uses a push-button switching knob to switch internal water paths via a lever principle, allowing water to flow from the outlets corresponding to different water paths. This device has numerous internal parts and an extremely complex structure. Another example is the water outlet device disclosed in patent CN210372135U, which uses a rotary knob to rotate a water distributor, enabling switching between different water paths. This distributor has a cylindrical structure with multiple water distribution holes on its end plate. Rotating the distributor allows communication with the internal water paths through these holes. This device also has numerous internal parts and a complex structure, making it difficult to manufacture and assemble. Utility Model Content

[0073] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0074] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0075] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0076] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0077] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0078] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0079] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a water outlet device that can switch between multiple water outlet modes, while simplifying the structure of the water outlet device, reducing the assembly difficulty, simplifying the manufacturing process, improving the user experience, and ensuring the overall appearance quality and sealing during the switching process.

[0080] Among them, combined Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The water outlet device includes a housing 1, a roller assembly 2, a switching knob 3, and a water inlet connector 7. The roller assembly 2 is rotatably fitted inside the housing 1, and the roller assembly 2 has multiple water inlets 20 spaced circumferentially. The multiple water inlets 20 are used to guide water flow through different water paths to the water outlet device. The switching knob 3 is connected to the roller assembly 2 and is used to drive the roller assembly 2 to rotate, thereby switching the water outlet mode. The water inlet connector 7 is located inside the housing 1 and is selectively connected to any of the water inlets 20.

[0081] The water outlet device provided in this embodiment rotates the roller assembly 2 relative to the inlet connector 7 within the housing 1 by operating the switching knob 3. During rotation, multiple water inlets 20 on the roller assembly 2 are sequentially connected to the inlet connector 7 through sealing connectors 8, allowing water from the inlet connector 7 to enter different water inlets 20 and then flow out of the water outlet device through different water paths, thus achieving the switching of water outlet modes. In this water outlet device, multiple water inlets 20 are arranged around the circumference of the roller assembly 2. Switching between the water paths corresponding to the multiple water inlets 20 can be achieved simply by operating the switching knob 3. This convenient operation simplifies the structure of the water outlet device, reduces assembly difficulty, simplifies manufacturing processes, and improves the user experience. Since only one switching knob 3 is needed to switch between multiple water outlet modes, it helps ensure the overall appearance quality of the water outlet device.

[0082] like Figure 2 and Figure 3 As shown, the water outlet device also includes a sealing joint 8 and a first elastic element 9. Both the sealing joint 8 and the first elastic element 9 are located within the housing 1. The sealing joint 8 is situated between the water inlet joint 7 and the roller assembly 2, and the first elastic element 9 is situated between the sealing joint 8 and the water inlet joint 7. The water inlet joint 7 is connected to any water distribution inlet 20 via the sealing joint 8. The sealing joint 8 abuts against the roller assembly 2 under the elastic force of the first elastic element 9. By providing the sealing joint 8 and the first elastic element 9, the sealing joint 8 can abut against the outer wall of the roller assembly 2 under the elastic force of the first elastic element 9, ensuring a tight seal between the sealing joint 8 and the roller assembly 2 and preventing gaps between them that could disrupt the water circuit switching function.

[0083] Moreover, in this water outlet device, multiple water inlets 20 are arranged around the circumference of the roller assembly 2. With the sealing contact of the sealing joint 8, the water path corresponding to the multiple water inlets 20 can be switched simply by rotating the switching knob 3. The operation is convenient. While realizing the switching of multiple water outlet modes, it can simplify the structure of the water outlet device and ensure the sealing during the switching process.

[0084] For example, the sealing joint 8 is made of rubber, possessing a certain strength and elastic deformation capability, and can stably and reliably seal against the roller assembly 2. The first elastic element 9 can be a spring.

[0085] See Figure 2 The water inlet connector 7 is provided with a water inlet channel 71, and the sealing connector 8 is provided with a water guide channel 81. The end of the water inlet channel 71 away from the sealing connector 8 is the water inlet 70 of the water outlet device. The water inlet 70 is connected to the water guide channel 81 through the water inlet channel 71. The downstream of the water guide channel 81 is connected to any water distribution inlet 20 of the roller assembly 2.

[0086] like Figure 2 and Figure 3 As shown, the sealing joint 8 has a contact arc surface 82 on the side facing the roller assembly 2, and the contact arc surface 82 seals against the outer wall of the roller assembly 2. In this embodiment, the curvature of the contact arc surface 82 is consistent with the curvature of the outer wall of the roller assembly 2, so that the contact arc surface 82 can be tightly fitted to the outer wall of the roller assembly 2 under the elastic force of the first elastic member 9, avoiding water leakage between the roller assembly 2 and the sealing joint 8 during the rotation and switching process.

[0087] like Figure 2 and Figure 5 As shown, the housing 1 has a first step structure 131, and the sealing joint 8 has a second step structure 83. The second step structure 83 engages with the first step structure 131 along the water inlet direction of the water inlet joint 7, thereby limiting the sealing joint 8 and facilitating its positioning during assembly. Furthermore, the housing 1 also has a third step structure 133, and the water inlet joint 7 has a fourth step structure. The fourth step structure engages with the third step structure 133 along the water inlet direction of the water inlet joint 7, and the water inlet joint 7 is threaded into the housing 1. During installation, the sealing joint 8, the first elastic element 9, and the water inlet joint 7 can be sequentially placed into the housing 1. The water inlet joint 7 is then screwed on. When the fourth step structure engages with the third step structure 133, it indicates that the water inlet joint 7 is properly installed. Under the elastic force of the first elastic element 9, the sealing joint 8 abuts against the first step structure 131 through the engagement of the second step structure 83.

[0088] See Figure 3 and Figure 5 One of the outer wall of the sealing joint 8 and the inner wall of the housing 1 is provided with an anti-rotation protrusion 132, and the other is provided with an anti-rotation groove 85. The anti-rotation protrusion 132 is engaged in the anti-rotation groove 85 to prevent the sealing joint 8 from rotating around the water inlet direction after installation, and to avoid a loose fit between the contact arc surface 82 and the outer wall of the roller assembly 2. Specifically, in this embodiment, two opposing anti-rotation protrusions 132 are provided on the inner wall of the housing 1, and an anti-rotation groove 85 is provided on each of the opposite sides of the sealing joint 8. The two anti-rotation protrusions 132 and the two anti-rotation grooves 85 are engaged one-to-one to improve the stability of the sealing joint 8 after installation.

[0089] See Figure 2 and Figure 3One end of the sealing joint 8 is provided with a sealing insert 84, and the sealing insert 84 defines an installation groove 86. One end of the water inlet joint 7 is provided with a limiting cylinder 72, and one end of the sealing joint 8 is inserted into the limiting cylinder 72 and makes sealing contact with the inner wall of the limiting cylinder 72, ensuring that the water inlet channel 71 can be sealed and connected with the water guide channel 81. The first elastic element 9 is provided in the space enclosed by the installation groove 86 and the limiting cylinder 72. This space not only provides an installation base for the first elastic element 9, but also improves the installation stability of the first elastic element 9, prevents the first elastic element 9 from shifting, and has a compact and reasonable structure.

[0090] Furthermore, a positioning cylinder 73 protrudes from the limiting cylinder 72. One end of the first elastic member 9 abuts against the bottom wall of the mounting groove 86, and the other end is fitted onto the positioning cylinder 73, further improving the installation stability and preventing random movement. Specifically, the aforementioned fourth step structure is formed between the outer wall of the limiting cylinder 72 and the outer peripheral wall of the water inlet connector 7.

[0091] like Figure 6 and Figure 7 As shown, one of the switching knob 3 and the housing 1 is provided with an elastic limiting member 4, and the other is provided with multiple limiting slots 1121. The multiple limiting slots 1121 are circumferentially distributed around the rotation axis of the roller assembly 2 and correspond one-to-one with multiple water inlets 20. The elastic limiting member 4 can be detachably engaged with any of the limiting slots 1121. When the switching knob 3 is rotated so that the water guide channel 81 of the sealing joint 8 is aligned and connected with the multiple water inlets 20 in sequence, the elastic limiting member 4 can be sequentially engaged into the multiple limiting slots 1121 to achieve locking and positioning. On the one hand, the engagement of the elastic limiting member 4 with the limiting slots 1121 can position the switching knob 3 in the current position, so that the water outlet device keeps water dispensing in the current mode and will not switch arbitrarily. On the other hand, during the process of the elastic limiting member 4 engaging and disengaging from the limiting slots 1121, it can provide tactile feedback to the user through vibration, so that the user can know the switching of the water outlet mode through touch, providing a strong operating feel.

[0092] In this embodiment, a plurality of limiting slots 1121 are provided at one end of the housing 1, and the aforementioned elastic limiting member 4 is installed on the switching button 3. Of course, in other embodiments, the limiting slots 1121 can also be provided on the switching button 3, and the elastic limiting member 4 can be installed on the housing 1.

[0093] Specifically, see Figure 7The elastic limiting member 4 includes a limiting post 41 and a second elastic member 42. A mounting cylinder 35 protrudes from the switching button 3. The limiting post 41 is movably disposed within the mounting cylinder 35 and engages or disengages from the limiting groove 1121. The second elastic member 42 is positioned between the limiting post 41 and the inner wall of the mounting cylinder 35. Under the action of the second elastic member 42, the limiting post 41 elastically expands and contracts within the mounting cylinder 35 to engage or disengage from the limiting groove 1121. Furthermore, the end surface of the limiting post 41 is spherical, and the limiting groove 1121 is a spherical groove, facilitating the engagement or disengagement of the end of the limiting post 41 from the limiting groove 1121.

[0094] It is understandable that when the elastic limiting member 4 is installed on the housing 1, the mounting cylinder 35 can be protruded on the housing 1.

[0095] like Figure 6 As shown, the housing 1 is provided with a first limiting boss 1122 and a second limiting boss 1123, and a plurality of limiting slots 1121 are located between the first limiting boss 1122 and the second limiting boss 1123. The first limiting boss 1122 and the second limiting boss 1123 stop the elastic limiting member 4 in the rotation direction of the switching button 3, so that the switching button 3 rotates within a certain angle range, and avoids the switching button 3 from rotating beyond its travel and thus failing to switch the water outlet mode smoothly.

[0096] It is understandable that when the elastic limiting member 4 is installed on the housing 1, the limiting slot 1121, the first limiting boss 1122 and the second limiting boss 1123 can be set on the switching button 3.

[0097] like Figure 6 and Figure 7 As shown, the housing 1 includes a first cylinder 11, a second cylinder 13, and an end cap 12. The first cylinder 11 includes a main body 111, with an end plate 112 and a mounting port 113 at each end. The roller assembly 2 is inserted into the main body 111 through the mounting port 113 and is coaxial with and rotatably engaged with the main body 111. The end cap 12 covers the mounting port 113, and the switching button 3 is mounted on the end plate 112. That is, the end cap 12 and the switching button 3 are located at opposite ends of the first cylinder 11 along the axial direction. The mounting port 113 at one end is used to insert the roller assembly 2 and is covered by the end cap 12, making assembly simple and convenient. The aforementioned limiting groove 1121, the first limiting boss 1122, and the second limiting boss 1123 can be arranged on the end plate 112. When switching the water outlet mode, the user only needs to turn the switching button 3 mounted on the end plate 112.

[0098] The second cylinder 13 and the main body 111 of the first cylinder 11 are connected and their axes intersect. The water inlet connector 7, the sealing connector 8, and the first elastic element 9 are all located inside the second cylinder 13. The water inlet direction of the water inlet connector 7 is the axial direction of the second cylinder 13. When the roller assembly 2 rotates around the axis of the main body 111, multiple water inlets 20 can be connected sequentially to the water guide channel 81 of the sealing connector 8.

[0099] Some existing water outlet devices have a pressurized water output mode, which can spray high-pressure water jets to rinse sinks, floors, and other areas, facilitating cleaning for users. However, users may accidentally switch the device to pressurized water output mode, causing a sudden burst of high-pressure water that could wet users, electrical equipment in the bathroom, etc., posing a certain safety hazard.

[0100] Based on the above-mentioned problems, in the water outlet device provided in this embodiment, one of the housing 1 and the switch button 3 is provided with a locking shell 14 facing the other, and the other of the housing 1 and the switch button 3 is provided with a locking tongue 31. The locking shell 14 and the locking tongue 31 cooperate with each other to prevent the user from accidentally opening a certain water outlet mode, avoiding accidental spraying of water onto the user and electrical equipment in the bathroom, thereby improving safety and user experience.

[0101] Specifically, such as Figure 1 , Figure 6 as well as Figure 7 As shown, the housing 1 is provided with a first water outlet 121; the switch button 3 has a first position that allows the water inlet connector 7 to communicate with the first water outlet 121 through a water distribution inlet 20 of the roller assembly 2.

[0102] The lock housing 14 is provided with a guide channel 141 and a clearance channel 142 communicating with the guide channel 141. The guide channel 141 is inclined relative to the rotation axis of the roller assembly 2. A gravity self-locking member 15 is slidably engaged in the guide channel 141. The gravity self-locking member 15 is used to switch between a locked position and an unlocked position under its own weight. When the gravity self-locking member 15 is in the locked position, the gravity self-locking member 15 blocks the clearance channel 142. When the gravity self-locking member 15 is in the unlocked position, the gravity self-locking member 15 opens the clearance channel 142, so that the bolt 31 passes through the clearance channel 142, thereby switching the switch button 3 to the first position.

[0103] In this embodiment, when the switching knob 3 is in the first position, the water inlet 70 is connected to the first water outlet 121 through the roller assembly 2. At this time, the corresponding water outlet mode is the first mode. When the switching knob 3 is rotated, the water outlet device can be switched to the first mode or switched from the first mode to other water outlet modes.

[0104] The water outlet device provided in this embodiment switches the water outlet mode by operating the switching knob 3 to drive the roller assembly 2 to rotate within the housing 1. When the switching knob 3 is rotated to the first position, the water inlet 70 on the housing 1 can connect with the first water outlet 121 through the roller assembly 2, thereby switching to the mode of water outlet from the first water outlet 121 (first mode). By setting the guide channel 141 of the lock housing 14 to be inclined relative to the rotation axis of the roller assembly 2, and setting a gravity self-locking member 15 in the guide channel 141, when the housing 1 changes its posture, the gravity self-locking member 15 can switch between the locked position and the unlocked position under its own gravity. When the gravity self-locking member 15 is in the unlocked position, the clearance channel 142 on the lock housing 14 opens, so that when the switching knob 3 is rotated to switch to the first position, the locking tongue 31 can pass through the clearance channel 142 without being blocked by the gravity self-locking member 15, thereby switching to the first mode of water outlet. When the gravity self-locking member 15 is in the locked position, it blocks the clearance channel 142 on the lock housing 14, preventing the bolt 31 from passing through the clearance channel 142, thereby preventing the switch button 3 from rotating to the first position. At this time, the water outlet device cannot dissipate water in the first mode. That is, before opening the first mode of the water outlet device, it is necessary to change the posture of the water outlet device so that the gravity self-locking member 15 moves from the locked position to the unlocked position, preventing the user from accidentally opening a certain water outlet mode, avoiding accidental spraying of water on the user and electrical equipment in the bathroom, and improving the safety and user experience.

[0105] Since the locking shell 14 protrudes from the switch knob 3 or is located on the side of the housing 1 facing the switch knob 3, rather than towards the interior of the housing 1, it does not reduce the internal space of the housing 1, thus avoiding occupying the installation space of the roller assembly 2. This reduces the design, manufacturing, and assembly difficulty of the roller assembly 2 and maximizes the internal water passage space of the roller assembly 2, allowing it to have a larger water flow and preventing insufficient water flow from the outlet device. Furthermore, the cooperation between the locking tongue 31 and the clearance channel 142 guides the rotation of the switch knob 3, increasing its stability during rotation.

[0106] In this embodiment, the lock housing 14 is disposed on the end plate 112 of the housing 1, the clearance channel 142 is disposed at the end of the lock housing 14 away from the end plate 112, and the lock tongue 31 is disposed on the switch button 3.

[0107] Specifically, in this embodiment, the switching knob 3 and the first water outlet 121 are respectively located at both ends of the housing 1 along the rotation axis of the roller assembly 2. The locking housing 14 is located at the end of the housing 1 away from the first water outlet 121. When the roller assembly 2 is in a horizontal state, the guide channel 141 extends downward at an angle. Furthermore, the water outlet device is rotatably connected to the water inlet pipe through the housing 1, so that the water outlet device can rotate to change its orientation.

[0108] When the water outlet device is in such a state Figure 8 and Figure 9 In the horizontal position shown, the gravity-locking member 15 slides downward along the guide channel 141 to the locking position under its own weight, blocking the clearance channel 142, so that the locking tongue 31 cannot pass through the clearance channel 142, and the water outlet device cannot switch to the first mode. When the water outlet device is rotated to deviate from the horizontal position, for example, when it is in the position shown... Figure 10 In the vertical position shown, the gravity self-locking component 15 slides along the guide channel 141 to the unlock position under its own gravity, no longer blocking the clearance channel 142. At this time, rotating the switching knob 3 can drive the locking tongue 31 through the clearance channel 142 to switch to the first position, so that water can be discharged from the first water outlet 121 at the lower end of the housing 1.

[0109] For example, the diameter of the first outlet 121 is small, and the first mode of water output through the first outlet 121 is pressurized water output mode. When the water output device is placed horizontally, it cannot be switched to pressurized water output mode. It can only be switched to pressurized water output mode when the water output device is tilted at a certain angle relative to the horizontal direction, which effectively prevents misoperation.

[0110] When the water outlet device is tilted at an angle of θ or greater relative to the horizontal, it can switch to pressurized water outlet mode. For example, θ is 45 degrees, meaning that when the water outlet device is tilted at an angle of 45 degrees or greater relative to the horizontal, it can switch to pressurized water outlet mode. Of course, in other embodiments, θ can take any value between 30 degrees and 85 degrees. When the water outlet device is in any position between an angle of θ relative to the horizontal and a vertical position, it can switch to pressurized water outlet mode.

[0111] When the switching knob 3 is in the first position, the elastic limiting member 4 engages with the limiting groove 1121 located at the end, so that the gravity self-locking member 15 can only restrict the switching knob 3 from rotating to the first position, and will not restrict the switching knob 3 from rotating to other positions. That is, when the water outlet device is horizontal, the gravity self-locking member 15 can only restrict the water outlet device to dissipate water in the pressurized water dissipation mode, and will not restrict the switching between other water dissipation modes.

[0112] like Figure 6 , Figure 7 as well as Figure 8As shown, the roller assembly 2 has a protruding insert 24 that penetrates the end plate 112. The switching knob 3 has an insert 34, into which the insert 24 is inserted. Both the cross-section of the insert 24 and the cross-section of the insert 34 are non-circular. The water outlet device also includes a fastener 5, which securely connects the insert 24 and the insert 34. When installing the switching knob 3 and the roller assembly 2, the insert 24 is inserted into the insert 34. Since both have non-circular cross-sections, circumferential limiting can be achieved. When the switching knob 3 is rotated, the roller assembly 2 can rotate synchronously. A recessed groove is provided on the side of the switching knob 3 facing away from the end plate 112. This recessed groove communicates with the inside of the insert 34. The fastener 5 is exemplarily a screw. The fastener 5 is passed through the recessed groove and screwed onto the insert 24. The head of the fastener 5 stops in the recessed groove, thus achieving a secure connection between the switching knob 3 and the roller assembly 2.

[0113] Furthermore, a seal 6 is provided in the groove, and the seal 6 is located on the side of the head of the fastener 5 facing away from the roller assembly 2 to prevent water from entering the groove.

[0114] like Figure 7 As shown, the switch knob 3 includes a switch knob housing 32 with a first chamber 30. The switch knob housing 32 covers one end of the housing 1 where the end plate 112 is located. An arc-shaped plate 33 protrudes from the bottom wall of the first chamber 30. A locking tongue 31 protrudes from the arc-shaped plate 33 and extends in an arc shape. The center of the arc of the arc-shaped plate 33 and the locking tongue 31 coincides with the axis of rotation. The arc-shaped extension of the locking tongue 31 facilitates its passage through the clearance channel 142 when the switch knob 3 rotates. The arc-shaped plate 33 increases the connection strength between the locking tongue 31 and the switch knob housing 32, improves the deformation resistance of the locking tongue 31, and prevents the locking tongue 31 from breaking or being damaged when the switch knob 3 is subjected to strong twisting force.

[0115] Specifically, the aforementioned mounting cylinder 35 and insert cylinder 34 are both protruding from the bottom wall of the first chamber 30.

[0116] like Figure 11 and Figure 12 As shown, the roller assembly 2 includes a first water distribution component 21, a water distribution plate 22, and a second water distribution component 23. The second water distribution component 23 is fastened to the first water distribution component 21 along the radial direction of the roller assembly 2, and the water distribution plate 22 is sandwiched between the first water distribution component 21 and the second water distribution component 23. A plurality of water distribution inlets 20 are spaced apart in the circumference of the first water distribution component 21, and the contact arc surface 82 of the sealing joint 8 is tightly fitted with the outer arc wall of the first water distribution component 21.

[0117] The first water distribution component 21 has a first water distribution outlet 215 and a second water distribution outlet 216 at one end along the axial direction. The outer peripheral wall of the second water distribution component 23 has a third water distribution outlet 233 and a fourth water distribution outlet 234. There are four water distribution inlets 20, which are respectively connected to the first water distribution outlet 215, the second water distribution outlet 216, the third water distribution outlet 233 and the fourth water distribution outlet 234 to realize water outlet through four channels.

[0118] Furthermore, the end cap 12 is provided with a first water outlet 121 and a second water outlet 161. The first water outlet 121 is located on the end face of the end cap 12 opposite to the switching knob 3 and is connected to the first water distribution outlet 215 to achieve water discharge in the first mode (i.e., the pressurized water discharge mode mentioned above). The second water outlet 161 is exposed through the outer peripheral wall of the cylinder body 111 and is connected to the second water distribution outlet 216 to achieve water discharge in the second mode. The third water distribution outlet 233 and the fourth water distribution outlet 234 are exposed through the outer peripheral wall of the cylinder body 111 and are connected to the first water distribution component 21 through the water distribution plate 22, respectively, to achieve water discharge in the third mode and the fourth mode.

[0119] Specifically, a water outlet 16 is installed on the end cap 12, and the water outlet 16 is provided with the aforementioned second water outlet 161. Combined with... Figure 13 and Figure 14 The side wall of the cylinder body 111 is provided with a first exposure port 1111 and a second exposure port 1112. The second water outlet 161 of the second water outlet 16 is exposed through the first exposure port 1111, and the third water outlet 233 and the fourth water outlet 234 are both exposed through the second exposure port 1112.

[0120] More specifically, the third water outlet 233 and the fourth water outlet 234 are distributed circumferentially around the roller assembly 2. The third water outlet 233 includes multiple shower holes 2331, and the fourth water outlet 234 includes a strip-shaped hole extending axially along the roller assembly 2. The water outlet directions of the shower holes 2331, the strip-shaped hole, and the second water outlet 161 are arranged at an angle to each other. When the water outlet device is horizontal, the second water outlet 161 faces upward, and the second mode is an upward-flowing mouthwash water outlet mode. The third mode when water is flowing from the multiple shower holes 2331 of the third water outlet 233 is a shower water outlet mode; the fourth mode when water is flowing from the strip-shaped hole is a waterfall water outlet mode. Users can switch between modes as needed.

[0121] Reference Figure 1When the water outlet device is rotated to a vertical position, rotating the switch knob 3 to the first position connects the water inlet 70 to the first water outlet 215 via the corresponding water inlet 20, resulting in water output from the first outlet 121 in a pressurized water output mode. When rotating the switch knob 3 to the second position, the water inlet 70 connects to the second water outlet 216 via the corresponding water inlet 20, resulting in water output from the second outlet 161 in a mouthwash output mode. When rotating the switch knob 3 to the third position, the water inlet 70 connects to the third water outlet 233 via the corresponding water inlet 20, resulting in water output from multiple shower holes 2331 in a shower water output mode. When rotating the switch knob 3 to the fourth position, the water inlet 70 connects to the fourth water outlet 234 via the corresponding water inlet 20, resulting in water output from strip-shaped holes in a waterfall water output mode.

[0122] like Figure 11 and Figure 12 As shown, the first water distribution component 21 includes a first cylindrical shell 217 and a plurality of first partitions 218 disposed within the first cylindrical shell 217. The plurality of first partitions 218 divide the interior of the first cylindrical shell 217 into a first water distribution channel 211, a second water distribution channel 212, a third water distribution channel 213, and a fourth water distribution channel 214. A plurality of water distribution inlets 20 are arranged circumferentially along the first cylindrical shell 217 and are connected to the first water distribution channel 211, the second water distribution channel 212, the third water distribution channel 213, and the fourth water distribution channel 214 in a one-to-one correspondence. The first water distribution outlet 215 is connected to the first water distribution channel 211, and the second water distribution outlet 216 is connected to the second water distribution channel 212.

[0123] The second water distribution component 23 includes a second cylindrical shell 235 and a second partition 236 disposed within the second cylindrical shell 235. The second partition 236 divides the interior of the second cylindrical shell 235 into a fifth water distribution channel 231 and a sixth water distribution channel 232. The water distribution plate 22 is provided with a first water passage 221 and a second water passage 222. The end cap 12 is provided with a seventh water distribution channel 122 and an eighth water distribution channel 123.

[0124] Specifically, the first water distribution channel 211 is connected to the first outlet 121 via the first water distribution outlet 215 and the seventh water distribution channel 122. The second water distribution channel 212 is connected to the second outlet 161 of the outlet 16 via the second water distribution outlet 216 and the eighth water distribution channel 123. The third water distribution channel 213 is connected to the third water distribution outlet 233 via the first water passage 221 and the fifth water distribution channel 231. The fourth water distribution channel 214 is connected to the fourth water distribution outlet 234 via the second water passage 222 and the sixth water distribution channel 232.

[0125] like Figure 6 and Figure 8As shown, the end cap 12 includes a sealing plate 127 and a third cylinder 124, a fourth cylinder 125, and a fifth cylinder 126 protruding from the sealing plate 127. A second chamber is formed between the fifth cylinder 126 and the sealing plate 127. The third cylinder 124 and the fourth cylinder 125 are both located within the second chamber, with the fourth cylinder 125 coaxially surrounding the third cylinder 124. The inner cavity of the third cylinder 124 forms a seventh water channel 122, and an eighth water channel 123 is formed between the third cylinder 124 and the fourth cylinder 125. A first latch 128 is provided on the fifth cylinder 126, which, in conjunction with… Figure 14 The inner wall of the cylinder body 111 is provided with a second buckle 1113. The fifth cylinder body 126 is inserted into the cylinder body 111 and is engaged with the second buckle 1113 by the first buckle 128.

[0126] In this embodiment, the end cap 12 is provided with a mounting hole that extends radially along the fifth cylinder 126. The water outlet 16 is installed in the mounting hole and can be engaged with the end cap 12 through a snap-fit ​​structure.

[0127] In summary, the water outlet device provided in this embodiment allows switching between four water outlet modes by rotating the switch knob 3: pressurized water outlet mode (first outlet 121), mouthwash outlet mode (second outlet 161), shower water outlet mode (third outlet 233), and waterfall water outlet mode (fourth outlet 234). Switching between modes requires only rotating the switch knob 3, without any other operation, making the structure simple and convenient. The elastic contact between the contact arc surface 82 of the sealing connector 8 and the outer wall of the roller assembly 2 ensures that the contact arc surface 82 remains firmly against the outer wall of the roller assembly 2, preventing leakage and water path disruption during mode switching. The elastic limiting member 4, in cooperation with multiple limiting slots 1121, stops the switch knob 3 during mode switching, facilitating its positioning and ensuring the water outlet mode remains stable without arbitrarily changing. It also provides tactile feedback during switching, improving the user experience.

[0128] Furthermore, by providing a matching lock housing 14 and lock tongue 31, and by installing a gravity self-locking component 15 within the lock housing 14, the water outlet device can be made to... Figure 9 When the device is in the horizontal (i.e., horizontal) position as shown, it cannot switch to the pressurized water outlet mode. It can only switch to pressurized water outlet mode when the outlet device is rotated to a certain angle (e.g., more than 45 degrees) relative to the horizontal direction. For example, when it is in a position such as... Figure 10 In the vertical position shown, the user can switch to the pressurized water output mode, outputting high-pressure water flow from the first outlet 121 at the lower end. This prevents the user from accidentally turning on the pressurized water output mode, avoiding accidental spraying of water onto the user and electrical equipment in the bathroom, thus improving safety and user experience.
