[0002] With social development and improved living standards, consumers have increasingly higher requirements for the aesthetics and user experience of water-dispensing devices such as shower heads. Most existing children's shower heads achieve their appeal and aesthetics by changing their appearance, but they lack visual impact and novelty, failing to fully stimulate children's curiosity. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and provide a water outlet device and shower head that creates a dynamic water tornado effect within the shower head and presents it in a visible manner, which can fully stimulate children's curiosity, guide children to understand physical phenomena, and enhance children's observation skills. Furthermore, it is equipped with a residual water discharge structure and a quick-disassembly structure. The residual water discharge structure can discharge the water flow remaining in the water outlet chamber after use, reducing water retention time and scale accumulation. The quick-disassembly structure ensures convenient cleaning of the shower head, so that the shower head will not affect its aesthetics and viewing effect due to dirt residue. At the same time, it can also reduce the harm to children's health caused by dirt and bacteria.

[0009] Furthermore, each of the aforementioned water outlet holes is located on the side wall of the shell.

[0010] Furthermore, the water inlet channel is coaxially arranged with the central axis of the shell itself, and its inner diameter is smaller than the diameter of the water outlet cavity.

[0011] A shower head employs the water outlet device as described above; the housing constitutes the shower head.

[0015] Furthermore, the inner wall of the handle is provided with a first limiting part to restrict the first rotating block from rotating relative to the first locking protrusion in the second direction when the first rotating block and the first locking protrusion are engaged; the elastic abutment component is provided with a second limiting part to prevent rotation relative to the handle; the second limiting part abuts against the first rotating block and forms an inclined surface engagement when the first rotating block and the first locking protrusion are engaged, to restrict the first rotating block from rotating relative to the first locking protrusion in a third direction opposite to the second direction; the inclined surface engagement is configured to allow the first rotating block to rotate relative to the first locking protrusion in a third direction under applied force.

[0016] Furthermore, the handle has a first abutting part; the elastic abutting component includes a sliding sleeve and a first elastic element; the sliding sleeve is anti-rotationally connected to the inner wall of the handle, and the second limiting part is provided at one end facing the water inlet connector; the two ends of the first elastic element act on the first abutting part and the end of the sliding sleeve facing away from the water inlet connector, respectively.

[0017] Furthermore, it also includes a drain assembly and a second elastic element; the handle is provided with a first water inlet channel, a second water inlet channel and a drain channel; the first water inlet channel is connected to the water inlet pipe; the two ends of the second water inlet channel are respectively connected to the first water inlet channel and the inclined flow channel; the drain channel extends to the bottom of the handle and is connected to the atmosphere; the drain assembly is axially slidably connected to the handle and is abutted axially by the second elastic element, and when water enters the first water inlet channel, it is blocked by water pressure to block the connection between the drain channel and the second water inlet channel, and when the water in the first water inlet channel is cut off, it is moved to open the connection between the drain channel and the second water inlet channel by the elastic reset action of the second elastic element.

[0018] Furthermore, it also includes: a water pipe, which is fixedly sleeved inside the handle and one end is sealed and inserted into the water inlet connector; a water inlet pipe, which is fixedly sleeved inside the handle and one end is sealed and sleeved into the water pipe, the other end of which extends out of the handle and connects to the water inlet pipe, the outer wall of which is spaced apart from the inner wall of the handle to form a first gap and the side wall is provided with a drain hole; the drain hole and the first gap are connected to form a drainage channel; the drain assembly slides to block or open the drain hole to switch the connection between the drainage channel and the second water inlet channel.

[0019] Furthermore, the inner wall of the inlet pipe and the inner wall of the outlet pipe are respectively provided with a second abutment and a third abutment; the drainage assembly includes: a piston, which is sleeved inside the inlet pipe and located between the second abutment and the end face of the outlet pipe, having a first water passage hole inside and a pressure-bearing surface on the hole wall facing the inlet of the inlet pipe, the first water passage hole connecting to the pipe inside the outlet pipe and forming the second water inlet channel; a sealing sleeve, which is fixedly sleeved on the outer wall of the piston and slides between the second abutment and the end face of the outlet pipe, and when it moves to abut against the end face of the outlet pipe, it blocks the connection between the drain hole and the second water inlet channel; the two ends of the second elastic member abut against the third abutment and the sealing sleeve respectively.

[0021] Furthermore, the inner wall of the handle is provided with a second snap-fit ​​protrusion; the outer wall of the water inlet pipe is provided with a second rotating block that rotatably snaps into the second snap-fit ​​protrusion; the outer wall of the water pipe is provided with a fourth abutment and a fifth abutment. When the water pipe is installed in the handle, the fourth abutment abuts against the bottom end of the water inlet connector, and the fifth abutment abuts against the second rotating block and restricts the second rotating block from axially moving and rotating away from the second snap-fit ​​protrusion.

[0022] Compared with existing technologies, the above solution has the following beneficial effects:

[0023] 1. The water outlet device of this technical solution has a partially or completely transparent or semi-transparent shell wall. Therefore, users can clearly observe the water tornado phenomenon formed inside the flow guiding component. The entire water outlet device is clean, beautiful, and easily meets the user's aesthetic needs. When the water outlet device is used for a special purpose (such as a child faucet or shower), the formation of the water tornado phenomenon is highly interesting, which can attract children's attention, improve their observation skills, and stimulate their curiosity and interest in exploring things. In addition, since a dynamic water tornado will be formed as long as water enters the shell, it is less likely to cause aesthetic fatigue compared to the traditional child-friendly water outlet structure that only modifies the appearance.

[0024] 2. In the water outlet device of this technical solution, when the water flows into the water outlet chamber through the guide component, some gas that has not yet been discharged from the water outlet will remain in the water outlet chamber. The formation of the water tornado can swirl the gas into the middle of the water column, forming a posture where the outside is water and the middle is gas. The water outlet will discharge the water first, thereby preventing the phenomenon of shaking and noise caused by unstable air pressure changes in the water outlet chamber. At the same time, the swirling effect of the water tornado can reduce the water impact intensity of the water outlet. Therefore, it is gentle and provides a good user experience for children.

[0025] 3. The water outlet device of this technical solution uses a first guide member with a first inclined hole to guide the flow. When the water flows through the first guide member, it forms a water column rotating around the central axis of the water inlet at the water outlet end of the guide member under the guidance of the first inclined hole. At this time, the gas in the water outlet chamber is squeezed out, causing the air pressure in the water outlet chamber to drop rapidly, thus quickly generating a water tornado phenomenon.

[0026] 4. The water outlet device of this technical solution includes a second guide and an impeller. The water flow forms a water column rotating around the central axis of the inlet channel under the guidance of the second oblique hole on the second guide. After the water flows out of the second guide, the rotating water flow obliquely impacts the blade and makes the impeller rotate rapidly, thereby quickly forming a clear water tornado posture under the condition of rapid pressure drop in the water outlet chamber.

[0027] 5. The water outlet device of this technical solution has a capsule-shaped or capsule-like shell. While ensuring aesthetics, it provides a suitable length dimension for the water outlet cavity to meet the requirements for waterspout formation. In addition, the swirling sidewalls of the capsule-shaped or capsule-like inner wall are conducive to guiding the water flow in the circumferential direction, thereby promoting the waterspout phenomenon.

[0028] 6. The water outlet device of this technical solution has the water outlet hole located on the side wall of the shell, which is conducive to the layout of a large number of water outlet holes and the planning of a wide water outlet area to improve the user's bathing needs; in addition, since the outer ring of the water tornado is all water flow, the form of setting the water outlet hole perpendicular to the central axis of the water tornado can ensure that all water outlet holes discharge water flow rather than gas first.

[0029] 7. The water outlet device of this technical solution has the water inlet channel coaxially set with the central axis of the shell itself, so that the water tornado can be formed in the middle of the shell and the viewing effect is excellent; the inner diameter of the water inlet channel is smaller than the cavity diameter of the water outlet cavity, so that the rotating water flow flowing into the water outlet cavity from the guide component will not be disturbed by the inner cavity wall of the water outlet cavity, thus improving the stability of the water tornado formation.

[0030] 8. This technical solution also provides a shower head, which has a housing and is able to form a stable water tornado inside the shower. This shower head has the same technical effect as the water outlet device mentioned above.

[0031] 9. The shower head of this technical solution has a detachable assembly structure in which the handle is screwed or rotated to connect to the water inlet connector on the housing. This allows the housing to be easily separated from the handle, which is beneficial for the maintenance and cleaning of the accessories. It also prevents dirt residue from affecting the appearance of the shower head and reduces the harm to children's health caused by dirt and bacteria.

[0032] 10. The shower head of this technical solution has a housing consisting of a face cover and a body. The molding process is simple and helps to reduce production costs.

[0033] 11. In this technical solution, the shower head housing and handle are rotated and locked together by a first locking protrusion and a first rotating locking block. The elastic abutment component ensures that when the first locking protrusion and the first rotating locking block are locked in place, they abut against each other axially and do not separate axially. This improves the stability of the rotating locking structure to a certain extent and effectively prevents the water inlet connector on the housing from coming off the handle.

[0034] 12. In the shower head of this technical solution, since the first snap-fit ​​protrusion is an independent protrusion structure, when the first rotating block and the first snap-fit ​​protrusion are snapped into place, there is a possibility that they will rotate and misalign relative to each other. Therefore, a fixed limiting part can be provided on the inner wall of the handle to limit the space in which the first rotating block rotates and misaligns relative to the first snap-fit ​​protrusion in the first direction after it is snapped into place, and a second limiting part can be provided on the elastic abutment component to limit the space in which the first rotating block rotates and misaligns relative to the first snap-fit ​​protrusion in the second direction after it is snapped into place. This limits the rotation and misalignment of the first rotating block relative to the first snap-fit ​​protrusion, so that there is no space for relative rotation and misalignment between the water inlet connector and the handle after they are snapped into place, thereby achieving the purpose of limiting the relative separation of the housing and the handle and improving the stability of the structure. The first rotating block and the second limiting part have a beveled fit structure, which allows the housing to push against the elastic abutment part under force to overcome the elastic force and move axially, and make way for the space used to limit the rotation of the first rotating block relative to the first locking protrusion in the second direction. This allows the first rotating block to disengage from the locking protrusion, achieving the purpose of convenient and quick disassembly and assembly between the housing and the handle.

[0035] 13. The shower head of this technical solution has an elastic contact component consisting of a sliding sleeve and a first elastic element, which has a relatively simple structure and reliable function.

[0036] 14. The shower head in this technical solution has a transparent or semi-transparent shell. Therefore, if residual water and scale residue remain in the water outlet after each use, the user can clearly observe the scale accumulated on the inner wall of the shell during use, resulting in poor aesthetics, unsatisfactory water tornado effect, and a poor user experience. This technical solution, by setting up a drainage channel, a drain component, and a second elastic element, ensures that when the shower head is shut off, the drain component is not subjected to water pressure and opens the connection between the drainage channel and the second water inlet channel, thereby achieving the purpose of draining residual water.

[0037] 15. The shower head of this technical solution achieves the setting of drainage channel with a simple structure by setting the water inlet pipe at intervals on the inner wall of the handle. The formation of drainage holes on the side wall of the water inlet pipe allows the drainage component to be blocked or opened in a reliable and simple manner by sliding.

[0038] 16. In this technical solution, the piston of the shower head serves as a stable support structure to support the sealing sleeve, ensuring that the sealing sleeve can form a stable axial sliding; when the sealing sleeve blocks the end face of the water pipe, it blocks the connection between the drain hole and the second water inlet channel, and the axial resistance improves the stability of the sealing structure.

[0039] 17. The shower head of this technical solution, with the water guide column extending towards the piston, reduces the water flow area in the inlet pipe, allowing the water to form a jet after flowing out through the second water passage, thus increasing the impact force of the water flow. On the other hand, it helps to guide the water flowing out of the second water passage to the pressure-bearing surface inside the piston, which helps to increase the impact strength of the water flow on the piston, thereby ensuring that the piston can reliably move under water pressure to block the connection between the drain hole and the second water inlet channel.

[0040] 18. The shower head of this technical solution has a rotating snap-fit ​​connection between the water inlet pipe and the handle, and the fifth abutment part on the water pipe restricts their relative rotation and offset. The structure is simple, the disassembly and assembly are convenient, and the maintenance work during use is simplified. Attached Figure Description

[0074] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0075] See Figures 1 to 19 , Figures 1 to 19 A schematic diagram of the showerhead structure according to an embodiment of the present invention is shown. Furthermore, the present invention also provides an embodiment of a water outlet device, wherein the showerhead embodiment is a specific application of the water outlet device embodiment. Therefore, the present invention mainly illustrates the technical solution to be protected by the water outlet device embodiment by describing the showerhead embodiment. However, it should be understood that the scenarios in which the water outlet device provided by the present invention can be applied should include, but are not limited to, water outlet devices capable of dispensing water, such as showerheads, faucets, and shower taps.

[0076] like Figures 1 to 19 As shown, in this embodiment, the shower head includes a housing 1, a flow guiding component 2, a handle 3, an elastic abutment component 4, a flow drain component 5, a second elastic element 6, a water pipe 7, and a water inlet pipe 8.

[0077] The housing 1 contains a shower head, which is provided with a water outlet chamber 10. The walls of the housing 1 are partially or entirely transparent or semi-transparent. The water outlet chamber 10 is provided with a water inlet channel 120 and several water outlet holes 111.

[0078] Specifically, in this embodiment, the shell 1 is capsule-shaped or capsule-like, with a water inlet at one end and a water inlet channel 120 inside. Its sidewall has several water outlet holes 111 arranged according to a predetermined rule. The material and manufacturing process of the shell 1 are consistent with those of commonly used shower heads, both being injection molded from plastic material. To reduce the difficulty of the molding process, in this embodiment, the shell 1 adopts a split molding form, comprising a transparent cover 11 and a body 12. The interface between the cover 11 and the body 12 is located at the junction of the shell and the body. In the longitudinal section of the central axis of body 1, after the two are spliced ​​together, they are fixed by ultrasonic welding. The face cover 11 is provided with a water outlet 111, and one end of the body 12 is provided with a water inlet connector 121. The water inlet connector 121 covers the end face of the face cover 11 so that the water inlet connector 121 is coaxial with the central axis of the housing 1 itself. The water inlet connector 121 is used to connect with the handle 3. It is connected to the handle 3 by a sealing screw or a rotating snap to facilitate disassembly, thereby facilitating subsequent maintenance and cleaning.

[0079] See Figure 15 and Figure 16 As shown, the water inlet connector 121 has a central hole and a water inlet channel 120 inside. The water inlet channel 120 connects to the water outlet chamber 10 to supply water to the water outlet chamber 10. The water in the water outlet chamber 10 flows out through the water outlet hole 111. Since the water inlet connector 121 is coaxial with the central axis of the housing 1 itself, the water inlet channel 120 can also be set to be coaxial with the central axis of the housing 1 itself, so that the waterspout can be formed in the exact center of the housing 1, enhancing the viewing effect.

[0080] In this embodiment, the water inlet connector 121 and the handle 3 are connected by a rotating snap-fit. Several first rotating snap blocks 1211 are evenly distributed along the circumference of the outer wall to be rotated and snapped with the handle 3.

[0081] The flow guiding component 2 is installed in the water inlet channel 120 and forms an inclined flow channel; the inclined flow channel guides the water flow into the water outlet cavity 10 in a swirling manner to form a water tornado in the water outlet cavity 10.

[0082] Specifically, such as Figures 2 to 6As shown, the flow guiding component 2 can be in, but is not limited to, the following two structural forms:

[0083] In the first structural form, the flow guiding assembly 2 includes a first flow guiding member 21, which is cylindrical in shape and has several first oblique holes 211 extending between its two ends and arranged circumferentially around the central axis of the inlet channel 120. These first oblique holes 211 guide the water passing through the first flow guiding member 21 into a water column rotating along the central axis of the inlet channel 120 in a first direction. This causes the water to enter the outlet chamber 10 in a swirling motion. During the process of the water entering the outlet chamber 10, the air pressure inside the outlet chamber 10 is squeezed out, causing a rapid drop in air pressure and thus quickly generating a waterspout phenomenon. The aforementioned first oblique holes 211 can be fan-shaped holes evenly distributed circumferentially on the first flow guiding member 21, or they can be spiral holes evenly distributed circumferentially on the first flow guiding member 21.

[0084] In the second structural form, the flow guiding assembly 2 includes a second flow guiding element 22 and an impeller 23. The structural characteristics of the second flow guiding element 22 are consistent with those of the first flow guiding element 21 described above. It is also cylindrical and has several second inclined holes 221 extending between its two ends and arranged circumferentially around the central axis of the inlet channel 120. These second inclined holes 221 can guide the water passing through the second flow guiding element 22 to form a water column that rotates along the central axis of the inlet channel 120 in a first direction. The impeller 23 is located on the second flow guiding element 22. Between the flow element 22 and the outlet cavity 10, generally speaking, the impeller 23 is disposed on the side of the second flow guide 22 facing the interior of the outlet cavity 10. The impeller 23 is rotatably connected to the second flow guide 22, and is configured to rotate due to the impact of the water column provided by the second flow guide 22. Specifically, after the rotating water flow from the second flow guide 22 obliquely impacts the blades on the impeller 23, the impeller 23 can rotate rapidly, thereby causing the water flow flowing into the outlet cavity 10 through the impeller 23 to quickly form a distinct waterspout shape. The aforementioned second oblique hole 221 can be a fan-shaped hole evenly distributed circumferentially on the second flow guide 22, or it can be a spiral hole evenly distributed circumferentially on the second flow guide 22.

[0085] Preferably, in this embodiment, the inner diameter of the inlet channel 120 is smaller than the inner diameter of the outlet cavity 10, so that the water flow introduced into the outlet cavity 10 by the flow guiding component 2 will not be disturbed by the inner wall of the outlet cavity 10, thereby ensuring the stability of the water tornado formation. It is worth noting that when the inner diameter of the shell 1 is uneven along the axial direction, the inner diameter of the outlet cavity 10 is based on the inner diameter of the middle section of the shell 1.

[0086] It is worth noting that when the showerhead provided in this embodiment is used as a children's product, lightweight starfish-shaped or small fish-shaped toys can be placed in the water outlet cavity 10 of the housing 1 and rotate with the water tornado to further enhance the product's fun. Of course, taking advantage of the water tornado's advantage of always being in a dynamic rotating state, the showerhead can also be cleaned by adding cleaning products inside the housing 1 during actual use. The cleaning products with granular cleaning effect are preferred, as the friction formed between the granular cleaning products and the inner wall of the housing 1 when rotating with the water flow helps to remove dirt.

[0087] The handle 3 has a tubular structure. In order to match the structural characteristics of the shower head, the handle 3 can preferably be made of transparent or semi-transparent material.

[0088] like Figures 8 to 12 As shown, in the shower head of this embodiment of the invention, the handle 3 is configured to form a rotatable engagement with the water inlet connector 121 on the housing 1. The inner wall of the handle 3 is provided with a first engagement protrusion 31. In this embodiment, the number of the first engagement protrusions 31 is at least three and corresponds to the number of the first rotating locking blocks 1211. Each first engagement protrusion 31 is an arc-shaped protrusion whose curvature matches the curvature of the inner wall of the handle 3. The first engagement protrusions 31 are spaced apart from each other and are evenly distributed circumferentially on the inner wall of the handle 3. When the housing 1 and the handle 3 are assembled, the water inlet connector 121 is inserted into the handle 3. During insertion, each first rotating locking block 1211 is inserted into the gap between the first engagement protrusions 31. After each first rotating locking block 1211 passes through the gap, the handle 3 is kept stationary while the housing 1 is rotated so that each first rotating locking block 1211 and the first engagement protrusion 31 form an axial abutment and restrict the water inlet connector 121 on the housing 1 from coming out of the handle 3.

[0089] It should be understood that the axial abutment between the first rotating block 1211 and the first engaging protrusion 31 is only an axial limit in one direction. If the end of the first rotating block 1211 that does not abut against the first engaging protrusion 31 or the end of the first engaging protrusion 31 that does not abut against the first rotating block 1211 is not restricted by other structures, then the abutment between the first rotating block 1211 and the first engaging protrusion 31 is unreliable. Therefore, this embodiment also provides an elastic abutment component 4, which slides inside the handle 3 and acts elastically along the axial direction between the inner wall of the handle 3 and the water inlet connector 121 to form a stable axial abutment when the first rotating block 1211 and the first engaging protrusion 31 are engaged in place, thereby preventing the housing 1 and the handle 3 from moving relative to each other in the axial direction.

[0090] When the housing 1 and the handle 3 are rotated and snapped together in the manner described above, in addition to forming the axial limiting relationship described above, preferably, a corresponding circumferential limiting structure should also be provided to prevent the first rotating locking block 1211 and the first locking protrusion 31 from rotating and misaligning relative to each other, causing the housing 1 and the handle 3 to separate relative to each other. The specific structures for forming axial and circumferential limiting when the housing 1 and the handle 3 are rotated and snapped together in the embodiments of the present invention will be described in detail below.

[0091] The inner wall of the handle 3 is also provided with a first limiting part 32. The number of first limiting parts 32 is the same as the number of first snap-fit ​​protrusions 31. The first limiting part 32 is a strip-shaped protrusion extending along the axial direction. One end of each first limiting part 32 is connected to one side of each first snap-fit ​​protrusion 31. This is to restrict the first rotating block 1211 from continuing to rotate relative to the first snap-fit ​​protrusion 31 in the second direction along the circumference when the first rotating block 1211 is snapped onto the first snap-fit ​​protrusion 31 in the second direction along the circumference. The second direction refers to the direction in which the first rotating block 1211 rotates to form an axial abutment with the first snap-fit ​​protrusion 31 after passing through the gap between two adjacent first snap-fit ​​protrusions 31 during the process of inserting the water inlet connector 121 into the handle 3. Similarly, after the first rotating block 1211 is rotated and snapped into place with the first snap-fit ​​protrusion 31, there should also be a corresponding limiting structure to restrict the first rotating block 1211 from rotating and shifting relative to the first snap-fit ​​protrusion 31 in a third direction opposite to the second direction.

[0092] Specifically, the elastic abutment component 4 includes a sliding sleeve 41 and a first elastic element 42. The sliding sleeve 41 is coaxially arranged with the handle 3 and slides against the inner wall of the handle 3 in a non-rotating manner. One end of the sliding sleeve 41 extends towards the end of the water inlet connector 121 located inside the handle 3 and is provided with several circumferentially distributed second limiting portions 411. The first elastic element 42 is a spring that is sleeved inside the handle 3. One end of the spring acts elastically on the end of the sliding sleeve 41 that does not have the second limiting portion 411, and the other end acts on the first abutment portion formed on the inner side of the handle 3. The first abutment portion can be directly formed by the inner wall of the handle 3 or it can be formed by other accessories. In fact, the first abutment portion only needs to be a structure that has no axial movement relative to the handle 3 and can be abutted by the first elastic element 42.

[0093] The number of second limiting parts 411 is the same as the number of first rotating blocks 1211. When the first rotating block 1211 rotates in the second direction until it forms an axial abutment with the first engaging protrusion 31, the sliding sleeve 41 moves towards the side where the water inlet connector 121 is located under the action of the first elastic member 42. Each second limiting part 411 is inserted between two adjacent first rotating blocks 1211. Since the sliding sleeve 41 cannot rotate relative to the handle 3, each second limiting part 411 restricts the other side of the first rotating block 1211, which is related to the first limiting part. The 32 cooperates with and abuts against both sides of each first rotating locking block 1211, thereby achieving the purpose of restricting the first rotating locking block 1211 from rotating and offset relative to the first locking protrusion 31 in the second or third direction. It should be understood that when the second limiting part 411 is inserted between two adjacent first rotating locking blocks 1211, the sliding sleeve 41 will always abut against the water inlet connector 121 under the action of the first elastic member 42, thereby achieving the purpose of making the first rotating locking block 1211 and the first locking protrusion 31 form a stable axial abutment after being locked in place.

[0094] To achieve quick assembly and disassembly, after the second limiting part 411 abuts the first rotating block 1211 into place, it is also necessary to ensure that the first rotating block 1211 can rotate out relative to the first locking protrusion 31. Therefore, in this embodiment, a second inclined surface 4111 is provided on the side of the second limiting part 411 that abuts the first rotating block 1211, and a first inclined surface 12111 is provided on the first rotating block 1211 that abuts against the second inclined surface 4111. The first inclined surface 12111 and the second inclined surface 4111 form an inclined surface fit, so that when the housing 1 is subjected to a certain rotational driving force, the first rotating block 1211 can be driven to push against the second limiting part 411 and the entire sliding sleeve 41 to overcome the elastic force of the first elastic member 42 and move away from the water inlet connector 121 until the second limiting part 411 disengages from the first rotating block 1211, ensuring that the first rotating block 1211 can disengage from the first locking protrusion 31, thereby ensuring that the housing 1 can be disassembled from the handle 3.

[0095] In this embodiment, the structure that prevents the sliding sleeve 41 from rotating relative to the handle 3 is achieved by the following structure: the outer wall of the sliding sleeve 41 is evenly distributed along the axial direction with a number of sliding protrusions 412 that are the same as the number of the first limiting parts 32. Each sliding protrusion 412 and one of the adjacent second limiting parts 411 constitute a pair of sliding components. The inner wall of the handle 3 is spaced apart and defined to form a slide rail for the sliding components to slide and restrict the rotation of the sliding components. The sliding protrusions 412 constituting the sliding components abut against one of the limiting parts, and the second limiting parts 411 constituting the sliding components abut against the other limiting part, thereby realizing the function of preventing the sliding sleeve 41 from rotating relative to the handle 3.

[0096] The aforementioned design of the water inlet connector 121 and the handle 3 as detachable structures ensures that the housing 1 can be easily separated from the handle 3, which is beneficial for the maintenance and cleaning of the accessories, avoids dirt residue affecting the appearance of the shower head, and further achieves the purpose of reducing the harm to children's health caused by dirt and bacteria.

[0097] Since the shell 1 wall is transparent or semi-transparent, if residual water and scale residue remain in the water outlet chamber 10 after each use, the user can clearly observe the scale residue accumulated on the inner wall of the shell 1 during use, resulting in poor aesthetics, unsightly water tornadoes, and a poor user experience. To address these issues, this embodiment incorporates a drainage channel 36, a drain assembly 5, and a second elastic element 6 to ensure that when the shower head is shut off, the drain assembly 5 is not subjected to water pressure and thus opens the connection between the drainage channel 36 and the second water inlet channel 35, thereby achieving the purpose of draining residual water.

[0098] like Figure 15 and Figure 16 As shown, the handle 3 is provided with a first water inlet channel 34, a second water inlet channel 35 and a drain channel 36; the first water inlet channel 34 is connected to the water inlet pipe 8; the two ends of the second water inlet channel 35 are respectively connected to the first water inlet channel 34 and the water inlet channel 120; the drain channel 36 extends to the bottom of the handle 3 and is connected to the atmosphere; the drain assembly 5 is axially slidably connected to the handle 3 and is abutted axially by the second elastic member 6. When water enters the first water inlet channel 34, it is blocked by water pressure from the drain channel 36 and the second water inlet channel 35. When the water in the first water inlet channel 34 is cut off, it is moved to open the connection between the drain channel 36 and the second water inlet channel 35 by the elastic reset action of the second elastic member 6.

[0099] In this embodiment, the first water inlet channel 34, the second water inlet channel 35, and the drain channel 36 are defined by the handle 3, the water pipe 7, and the water inlet pipe 8. The following will explain the composition of the first water inlet channel 34, the second water inlet channel 35, and the drain channel 36 and the principle of residual water discharge by specifically describing the specific structure of the water pipe 7 and the water inlet pipe 8, the drain assembly 5, and their assembly structure within the handle 3. Figures 15 to 19 As shown.

[0100] Both the water pipe 7 and the water inlet pipe 8 are tubular structures. The water pipe 7 is coaxially fixedly sleeved inside the handle 3, with one end sealed and inserted into the water inlet connector 121, and the other end sealed and sleeved into the water inlet pipe 8. The feature of fixing the water pipe 7 inside the handle 3 is achieved by the following structure: the inner wall of the handle 3 is provided with a second snap-fit ​​protrusion 33, and the outer wall of the water pipe 7 is provided with a fourth abutment part 72 and a fifth abutment part 73. The fourth abutment part 72 and the fifth abutment part 73 are both flanges formed on the outer wall of the water pipe 7. The water pipe 7 is fixed between the handle 3 and the water inlet connector 121. Before the 21-rotation snap-fit ​​is installed in the handle 3, the sliding sleeve 41 and the first elastic element 42 are sleeved between the inner wall of the handle 3 and the outer wall of the water pipe 7. When the handle 3 and the water inlet connector 121 are rotated and snap-fitted into place, the fourth abutment part 72 abuts against the bottom end of the water inlet connector 121, and the fifth abutment part 73 abuts directly or indirectly against the upper end of the second snap-fit ​​protrusion 33. The bottom end of the water inlet connector 121 and the upper end of the second snap-fit ​​protrusion 33 respectively abut against the fourth abutment part 72 and the fifth abutment part 73, thereby restricting the axial displacement of the water pipe 7 relative to the handle 3.

[0101] Specifically, the end of the water pipe 7 that is sealed and inserted into the water inlet connector 121 is the water pipe 7 inserted into the water inlet connector 121. The part of the pipe inside the water inlet connector 121 constitutes the water inlet channel 120. Of course, except for the embodiment in which the upper end of the water pipe 7 is inserted into the water inlet connector 121, in other cases where the water pipe 7 is not inserted into the water inlet connector 121, the water inlet channel 120 is directly formed by the inner channel of the water inlet connector 121. The outer wall of the water pipe 7 is provided with a groove, and the outer wall of the water pipe 7 is spaced apart from the inner wall of the water inlet connector 121. In the flow guiding assembly 2, the first flow guiding member 21 or the second flow guiding member 22 is provided with an annular wall. The inner wall of the annular wall is provided with a buckle. The annular wall is inserted between the outer wall of the water pipe 7 and the inner wall of the water inlet connector 121, and the buckle and the groove are engaged to achieve the connection of the flow guiding assembly 2 at the water inlet 120. The first flow guiding member 21 and the second flow guiding member 22 both include a flow guiding part with an oblique hole and a cover part. The cover part is fixedly welded to one end of the flow guiding part, and has a water passage hole communicating with the oblique hole and forming an annular wall. However, it is worth noting that the connection method between the flow guiding assembly 2 and the water pipe 7 is not limited to the implementation method provided in this embodiment. Other structures that can realize the quick assembly and disassembly of the flow guiding assembly 2 and the water pipe 7 or the water inlet connector 121 can also be considered in this embodiment.

[0102] In this embodiment, the end of the water pipe 7 that is sealed and connected to the water inlet pipe 8 is specifically the water pipe 7 being sealed and inserted into the water inlet pipe 8. The inner pipe of the water pipe 7 forms all or part of the second water inlet channel 35. Therefore, the water inlet channel 120 forms part of the second water inlet channel 35. The inner wall of the water pipe 7 is provided with a third abutment portion 71 facing the water inlet pipe 8. This third abutment portion is a stepped surface formed on the inner wall of the water pipe 7 for the drainage assembly 5 to abut against.

[0103] The inlet pipe 8 is detachably coaxially fixed inside the handle 3, with its outer wall spaced apart from the inner wall of the handle 3 to form a first gap. A drain hole 81 is provided on the side wall of the inlet pipe 8 near the water pipe 7. The drain hole 81 connects with the first gap to form a drain channel 36, which extends to the bottom of the handle 3 and is open to the atmosphere. A second abutment part 82 is provided inside the inlet pipe 8. The second abutment part 82 is a partition disposed inside the pipe of the inlet pipe 8. The partition is used for the drain assembly 5 to abut against and limit the movement of the drain assembly 5. The partition is provided with a second water passage hole 821, which is connected to the water inlet of the water inlet pipe 8 to form a first water inlet channel 34. In this embodiment, the second water passage hole 821 is connected to the inner pipe of the water pipe 7 to form a second water inlet channel 35. In addition, a water guide column 822 protruding towards the water passage hole is coaxially provided on the partition. The water guide column 822 serves to guide the water flow to the discharge component 5 and enhance the water flow impact force. The second water passage hole 821 is arranged along the periphery of the water guide column.

[0104] The drain assembly 5 includes a piston 51 and a sealing sleeve 52. The piston 51 is a tubular structure that is fitted inside the water inlet pipe 8 and located between the second abutment part 82 and the end face of the water pipe 7. It has a first water passage hole 511 inside and a pressure-bearing surface 512 facing the water inlet of the water inlet pipe 8 on the hole wall. The first water passage hole 511 is connected to the inner pipe of the water pipe 7. Since the first water passage hole 511 is located between the second water passage hole 821 and the water pipe 7, the second water passage hole 821 is connected to the inner pipe of the water pipe 7 to form a second water inlet channel 35. The water guide column 822 extends toward the pressure-bearing surface 512 but does not abut against the pressure-bearing surface 512. The sealing sleeve 52 is fixedly sleeved on the outer wall of the piston 51. It moves with the piston 51 between the end face of the water pipe 7 and the second abutment part 82. When the sealing sleeve 52 moves to abut against the end face of the end of the water pipe 7 located inside the water inlet pipe 8, it blocks the drain hole 81 and isolates the drain hole 81 from the communication between the drain hole 81 and the second water inlet channel 35. Preferably, in order to improve the reliability of the seal, in this embodiment, a sealing ring 74 is protruding from one end of the water pipe 7 for the sealing sleeve 52 to abut against. When the sealing sleeve 52 abuts against the water pipe 7, it seals with the sealing ring 74.

[0105] The second elastic element 6 is a spring, with its two ends abutting against the third abutment portion 71 and the sealing sleeve 52, respectively. Preferably, the piston 51 has a protruding post extending towards the water pipe 7 at one end, and the protruding post has a third water passage hole communicating with the first water passage hole 511. The second elastic element 6 is sleeved on the outer periphery of the protruding post and abuts against the third abutment portion 71 and the piston 51, thereby preventing the second elastic element 6 from tilting and improving the stability of the second elastic element 6.

[0106] In this embodiment, the drainage component 5 operates as follows: when water enters the first water inlet channel 34, the water flowing into the first water inlet hole 511 through the second water passage hole 821 is guided by the water guide column 822 and impacts the pressure bearing surface 512. Under the action of water pressure, the piston 51 and the sealing sleeve 52 overcome the elasticity of the second elastic element 6 and move towards the water pipe 7 until the sealing sleeve 52 abuts against the end face of the water pipe 7. At this time, the drain hole 81 is not connected to the second water inlet channel 35, and the water flowing in from the first water inlet channel 34 flows directly through the second water inlet channel 35. The water flows into the water outlet chamber 10 through the guide assembly 2. When the water in the first water inlet channel 34 is cut off, the water outlet chamber 10 is relatively large, so there is a lot of residual water in it. At this time, the water pressure on the piston 51 and the sealing sleeve 52 disappears, and they can move to abut against the second abutment part 82 under the action of the second elastic member 6 and their own gravity. The sealing sleeve 52 disengages from the abutment with the end face of the water pipe 7, and the drain hole 81 is connected to the second water inlet channel 35. Thus, the water remaining in the water outlet chamber 10 and the second water outlet channel can be discharged from the drain channel 36.

[0107] In this embodiment, the water inlet pipe 8 and the handle 3 are detachably coaxially fixed as follows: the second locking protrusion 33 inside the handle 3 is an arc-shaped protrusion whose curvature matches the inner wall of the handle 3. There are at least three second locking protrusions 33, and each second locking protrusion 33 is evenly distributed circumferentially. The outer wall of the water inlet pipe 8 is provided with a second rotating locking block 83 that rotates and engages with the second locking protrusion 33. The number of second rotating locking blocks 83 is the same as the number of second locking protrusions 33 and they correspond to each other. During installation, the water inlet pipe 8 is inserted into the handle 3, and each second rotating locking block 83 is aligned with the gap formed by the two second locking protrusions 33 inside the handle 3. After the second rotating locking block 83 passes through the gap, rotating the water inlet pipe 8 will cause the second rotating locking block 83 to axially abut against the second locking protrusion 3. 3. When the handle 3 is engaged with the water inlet connector 121, the fifth abutment part 73 of the water pipe 7 abuts against the end of the second rotating block 83 away from the second locking protrusion 33. In this way, the second rotating block 83 is restricted from axially disengaging from the second locking protrusion 33. At the same time, in this embodiment, the fifth abutment part 73 is also used to abut against the second rotating block 83 to restrict the second rotating block 83 from rotating and offset relative to the second locking protrusion 33. Specifically, the fifth abutment part 73 is provided with a number of limiting protrusions 731 that are the same as the number of second rotating blocks 83. When the fifth abutment part 73 abuts against the second rotating block 83, each limiting protrusion 731 is inserted between each second rotating block 83 and between each second locking protrusion 33, thereby restricting the rotation of the water inlet pipe 8 relative to the handle 3.

[0108] Preferably, in this embodiment, the water pipe 7 is designed to be unable to rotate relative to the handle 3. This prevents the limiting protrusions 731 on the water pipe 7 from rotating out of alignment and thus failing to restrict the rotation of the water inlet pipe 8 relative to the handle 3. Specifically, in this embodiment, the strip-shaped first limiting portion 32 extends to the fifth abutment portion 73. The inner wall of the handle 3 is also provided with limiting strips 37 that are parallel to the first limiting portion 32 and have the same number as the first limiting portion 32. Each limiting strip 37 and one of the first limiting portions 32 define an axial slide. The limiting protrusions 731 on the water pipe 7 slide in the axial slide and the side walls of both sides abut against the limiting strips 37 and the first limiting portion 32 that constitute the axial slide, thereby restricting the rotation of the water pipe 7 relative to the handle 3 and improving the stability of the structure.

[0109] In the actual assembly of the shower head provided in this embodiment, the assembled piston 51, sealing sleeve 52, and second elastic element 6 are fitted into the water inlet pipe 8 according to the predetermined structural features. Then, the water inlet pipe 8 is installed into the handle 3, and the water inlet pipe 8 is rotated so that the second rotating locking block 83 and the second locking protrusion 33 form an axial engagement. The first elastic element 42 and sliding sleeve 41 are fitted onto the outer periphery of the water pipe 7. Then, the water pipe 7 is inserted into the handle 3, and the limiting protrusion 731 on the water pipe 7 is lowered into each of the first elastic elements 42 and sliding sleeve 41. The gaps defined by the two rotating locking blocks 83 ensure that the water inlet pipe 8 cannot be detached from the handle 3. Then, the first guide member 21 or the second guide member 22 in the guide assembly 2 is sleeved and locked into place with the water pipe 7. Then, the end of the water pipe 7 equipped with the guide assembly 2 is inserted into the water inlet connector 121. The housing 1 is rotated until the second limiting part 411 of the sliding sleeve 41, which is moved to it by the action of the first elastic member 42, slides into the gaps defined by each of the first rotating locking blocks 1211. The assembly is then completed.

[0110] The shower head provided in this embodiment has a partially or completely transparent or semi-transparent shell 1. Therefore, users can clearly observe the water tornado phenomenon formed inside the flow guide component 2. The entire water outlet device is refreshing and beautiful, easily meeting the user's aesthetic needs. When the water outlet device is used for a special purpose (such as a child-friendly faucet or shower head), the formation of the water tornado phenomenon is highly interesting, attracting children's attention, enhancing their observation skills, and stimulating their curiosity and interest in exploring things. In addition, since a dynamic water tornado posture is formed whenever water enters the shell 1, it is less likely to cause aesthetic fatigue compared to the traditional child-friendly water outlet structure that only modifies the appearance. As water flows into the outlet chamber 10 through the guide component 2, some gas that has not yet been discharged from the outlet hole 111 remains in the outlet chamber 10. The formation of the water tornado can swirl the gas into the middle of the water column, creating a shape where the water flows on the outside and the gas flows in the middle. The outlet hole 111 discharges the water first, thus preventing shaking and noise caused by unstable air pressure changes in the outlet chamber 10. At the same time, the swirling effect of the water tornado can reduce the water impact intensity of the outlet hole 111. Therefore, it is gentle and provides a good user experience for children.
