Description

TECHNICAL FIELD

[0001] The utility model relates to sanitary equipment technical field, concretely relates to a water outlet device. BACKGROUND

[0002] Traditional water outlet devices mainly meet basic showering needs, while modern water outlet devices pay more attention to functionality and comfort. Multifunctional water outlet devices that integrate massage, cleaning and comfort have appeared on the market. These multifunctional water outlet devices not only provide richer showering experiences. In existing massage water outlet devices, in order to achieve fastening of the water outlet device body and the functional module, a magnet attraction force or a clamping method is usually used. The magnet attraction force method assembles magnets on the water outlet device body and the functional module respectively, and uses the mutual attraction force between the magnets to maintain the fastened state. Although this method achieves convenient connection to some extent, it also causes an increase in cost. On the other hand, the clamping method has relatively low cost, but is prone to loosening in actual use. In particular, when the massage head rotates, the clamping position is prone to loosening due to uneven stress or wear caused by long-term use, which affects the massage effect and user experience. In addition, when the functional module is used independently, the clamping position may also affect the hand feeling and reduce the comfort of the user. SUMMARY

[0003] The utility model aims to overcome the above-mentioned defects or problems in the background art, and provides a water outlet device that connects the functional module and the water outlet device body by a more economical and reliable fastening method.

The water outlet part is provided with a connecting hole in a first direction. The functional module is detachably connected to the connecting hole. The outer side wall of the functional module is provided with an elastic member. When the functional module is connected to the connecting hole, the elastic member is deformed and abuts against the hole wall of the connecting hole, and the functional module is fixed relative to the body by friction force.

[0006] The second technical solution is based on the first technical solution, wherein the elastic member further includes a first elastic member extending in the first direction. The first elastic member is in contact with the hole wall and generates a circumferential friction force to prevent the functional module from rotating circumferentially relative to the hole wall.

[0007] The third technical solution is based on the second technical solution, wherein the first elastic member is at least partially composed of an elastic friction material, and a plurality of tapered protrusions extending in the first direction are formed on the outer peripheral surface of the first elastic member in a radial direction. The tapered surface of the tapered protrusions gradually narrows in the first direction.

[0008] The fourth technical solution is based on the third technical solution, wherein the conical protrusions are in interference fit with the hole wall.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the first elastic member is a soft rubber friction ring, and the conical protrusions are uniformly distributed along the circumference of the friction ring.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the first elastic member and the functional module are fixed by secondary injection molding or interference fit.

[0015] From the above description of the various embodiments of the present application, it can be seen that, compared with the prior art, the various embodiments of the present application have the following beneficial effects:

[0016] In the first technical solution and related embodiments, the water outlet device is provided with an elastic member on the outer side wall of the functional module, when the functional module is attached to the connecting hole of the body, the elastic member will deform and tightly fit the hole wall of the connecting hole. This design utilizes friction to achieve stable fixation of the functional module relative to the body, so that the functional module can be conveniently and firmly installed on the body, and it is also convenient for users to disassemble and replace the functional module according to needs, improving the flexibility and practicality of the water outlet device.

[0017] In the second technical solution and related embodiments, the first elastic member can be in close contact with the hole wall and generate a circumferential friction force, preventing the functional module from rotating relative to the hole wall in the circumferential direction, achieving a rotation-stopping fit between the functional module and the hole wall, and enhancing the stability of the functional module on the body.

[0018] In the third technical solution and related embodiments, the first elastic member is at least partially made of an elastic friction material and has a plurality of conical protrusions formed along its outer circumferential surface in a radial direction. These conical protrusions extend in the first direction, increasing the contact area between the first elastic member and the hole wall and generating a greater friction force, preventing the functional module from rotating relative to the hole wall in the circumferential direction. In addition, the conical surface gradually changes from narrow to wide towards the direction of the connecting hole, gradually adapting to the shape of the hole wall during installation, facilitating smooth installation of the functional module.

[0019] In the fourth technical solution and related embodiments, the conical protrusions form an interference fit with the hole wall, further enhancing the friction force between the conical protrusions and the hole wall and preventing the functional module from rotating relative to the hole wall in the circumferential direction.

[0020] In the fifth technical solution and related embodiments, the friction ring made of soft rubber and the uniformly distributed conical protrusions thereon optimize the contact area between the first elastic member and the hole wall, making the friction force distribution more uniform and more stable in preventing the functional module from rotating in the circumferential direction.

[0021] In the sixth technical solution and related embodiments, both the secondary injection molding and the interference fit methods can ensure a firm connection between the first elastic member and the functional module.

[0022] In the seventh technical solution and related embodiments, by introducing a second elastic member and sleeving it on the functional module, and simultaneously using the circumferentially arranged annular grooves on the hole wall that are adapted to the second elastic member, the functional module is fixed in the first direction. After the second elastic member is clamped in the annular groove, it tightly adheres to the side wall of the groove and abuts against the hole wall due to its elastic properties, utilizing the friction force to prevent the functional module from sliding in the first direction.

[0023] In the eighth technical solution and related embodiments, the elastic deformation of the O-ring and the friction force generated by the tight fit with the annular groove prevent the functional module from sliding and falling in the first direction.

[0024] In the ninth technical solution and related embodiments, the functional module of the water outlet device is designed as a massage module, enriching the user's shower experience and providing personalized options. The functional module is composed of a main piece, a massage head rotationally connected to the main piece, and an elastic piece installed on the main piece. The massage head is a detachable and replaceable component, allowing users to choose different types or functions of massage heads according to personal preferences and needs. The elastic piece deforms and abuts against the hole wall during installation, securely fixing the main piece of the functional module relative to the body through friction, ensuring that the massage head does not cause the main piece to rotate relative to the body or slide and fall in the first direction during rotation, and ensuring that the massage head can rotate independently and stably.

[0025] In the tenth technical solution and related embodiments, the functional module ensures stable and reliable rotation of the massage head through the cooperation of the motor and gear transmission set, as well as the limiting cooperation of the transmission shaft and the massage head. Users can control the start and stop of the massage head by operating the switch, improving the convenience of use. Different speed gears can be selected according to personal preferences and needs to adjust the speed of the motor, and the gear transmission set can form the required speed reduction ratio to control the rotation speed of the transmission shaft and the massage head. The design of the rechargeable electric drive device also makes the water outlet device more flexible during use, eliminating the need for an external power cord and freeing the user from the limitations of the power source location, improving user convenience, allowing the functional module to be used independently when separated from the water outlet device, and expanding the functionality and application scenarios of the water outlet device.

[0043] Referring to Figures 1 to 8 As shown in Figure 1 A water outlet device includes a body 1 and a functional module 2. The water outlet device is a shower, a spray gun, etc., but is not limited thereto.

[0044] The body 1, as shown in Figure 1 , Figure 2 and Figure 4 The body 1 is the core support structure of the water outlet device, which not only ensures the effective circulation of water flow, but also provides a stable and easy-to-install support platform for the functional module 2. The body 1 mainly consists of a handle 10 and a water outlet part 11.

[0045] The handle 10 is located on one side of the body 1, which is convenient for users to hold and control. The handle 10 is internally provided with a water flow channel, which is connected to the water inlet and the water outlet part 11, ensuring smooth water flow.

[0046] The water outlet part 11 is located at one end of the body 1, and its shape can be cylindrical or other suitable shapes, such as conical, polygonal column, etc. In this embodiment, the water outlet part is cylindrical. The water outlet part 11 is provided with a connecting hole 12 along the first direction, which is used to install the functional module 2. The connecting hole 12 can be a through hole along the first direction, or a blind hole along the first direction. In this embodiment, the connecting hole 12 is a through hole along the first direction. The water outlet part 11 is arranged around the outer periphery of the hole wall 14 to ensure that the installation and use of the functional module 2 do not affect the water outlet of the water outlet device.

[0047] The functional module 2, as shown in Figure 2 and Figure 3 It is detachably connected to the connecting hole 12. The functional module 2 can be a massage module or other forms of functional modules, such as a music playing module, and in this embodiment, the functional module 2 is a massage module. The massage module mainly consists of a main piece 20, a massage head 21 and an elastic piece.

[0048] The main piece 20 is the main structure of the functional module 2, which comprises a motor 27, a gear transmission set 28 and a transmission shaft 29. The main piece 20 is configured to be rechargeable or to use a battery as an electric drive device. In this embodiment, the main piece 20 is a rechargeable electric drive device, which is provided with a charging contact 25 at one end of the main piece 20 close to the massage head 21, for providing power for the motor 27. The rechargeable electric drive device does not need an external power cord, making the water outlet device more flexible during use and not limited by the location of the power source.

[0049] The motor 27 provides power for the massage head 21.

[0050] The gear transmission set 28 is connected with the output end of the motor 27, for adjusting the rotating speed of the motor 27 and driving the transmission shaft 29 to rotate. Specifically, the gear transmission set 28 comprises a driving gear and a driven gear. The driving gear is directly connected with the output end of the motor 27 and receives power from the motor. The driven gear is connected with the transmission shaft 29 and transmits power through the meshing of the gears. When the motor 27 starts, the output end drives the driving gear to rotate. The driving gear transmits power to the driven gear through meshing, thereby driving the transmission shaft 29 to rotate. By adjusting the gear ratio, the rotating speed of the motor can be adjusted.

[0051] The transmission shaft 29 is connected with and driven by the gear transmission set 28, and is rotationally connected with the massage head 21 along the rotating axis direction to drive the massage head 21 to rotate relative to the body 1. The end of the transmission shaft 29 is fixedly connected with the massage head 21, ensuring synchronous rotation of the two. Specifically, the transmission shaft 29 and the massage head 21 are rotationally connected in the form of pin connection, set screw connection, etc.

[0052] The switch assembly 26 is located at one end of the main piece 20 along the first direction, which comprises an operation switch and a gear selection switch.

[0053] The operation switch is used to control the start and stop of the motor 27.

[0054] The gear selection switch is used to adjust the rotating speed of the motor 27, and users can select different speed gears according to their own preferences and needs.

[0055] In this embodiment, the functional module 2 ensures that the massage head 21 can stably and reliably rotate through the cooperation of the motor 27 and the gear transmission set 28, and the rotation-stopping connection of the transmission shaft 29 and the massage head 21. The user can control the start and stop of the massage head 21 by operating the switch, improving the convenience of use. And you can choose different speed gears according to your own preferences and needs, adjust the speed of the motor 27, and the gear transmission set 28 can form the required speed reduction ratio to control the rotation speed of the transmission shaft 29 and the massage head 21. The design of the rechargeable electric drive device also makes the water outlet device more flexible during use, without the need for an external power cord, freeing it from the limitations of the power source location, improving the convenience of the user, and allowing the functional module 2 to be used independently when it is separated from the water outlet device, expanding the functionality and application scenarios of the water outlet device.

[0056] The elastic member is located on the outer side wall of the functional module 2. When the functional module 2 is attached to the connecting hole 12, the elastic member deforms and abuts against the hole wall 14 of the connecting hole 12, fixing the functional module 2 relative to the body 1 through friction. Specifically, the elastic member is sleeved on the main member 20. The elastic member includes a first elastic member 22 and a second elastic member 23.

[0057] The first elastic member 22, as shown in Figure 3 and Figure 5 , is arranged circumferentially along the main member 20 and extends in the first direction. The first elastic member 22 contacts the hole wall 14 and generates a circumferential friction force to prevent the functional module 2 from rotating circumferentially relative to the hole wall 14. The first elastic member 22 is at least partially made of an elastic friction material and forms a plurality of tapered protrusions 24 extending in the first direction along the outer circumferential surface thereof, the tapered surface of which gradually narrows in the first direction. Specifically, the elastic friction material is a soft rubber material. These tapered protrusions 24 contact the hole wall 14 of the connecting hole 12 and generate sufficient circumferential friction force to prevent the main member 20 from rotating circumferentially relative to the hole wall 14. In this embodiment, the first elastic member 22 is a soft rubber friction ring arranged around the outside of the main member 20, and a plurality of tapered protrusions 24 are uniformly distributed on the friction ring in the circumferential direction. The tapered protrusions 24 form an interference fit with the hole wall 14, further enhancing the rotation-stopping effect. The first elastic member 22 and the main member 20 are fixed by two-shot injection molding or connected by interference fit, ensuring firm connection between the two.

[0058] In this embodiment, the first elastic member 22 is at least partially made of an elastic friction material and forms a plurality of tapered protrusions 24 radially protruding from the outer circumferential surface thereof. These tapered protrusions 24 extend in the first direction, increasing the contact area between the first elastic member 22 and the hole wall 14 and generating greater friction to prevent the functional module 2 from rotating circumferentially relative to the hole wall 14. In addition, the tapered surface gradually changes from narrow to wide in the direction of the connecting hole 12, gradually adapting to the shape of the hole wall 14 during installation, facilitating smooth installation of the functional module 2.

[0059] The second elastic member 23 is sleeved on the main member 20 and elastically cooperates with the hole wall 14 of the connecting hole 12 to prevent the main member 20 from sliding in the first direction. Specifically, the hole wall 14 is provided with an annular groove 13 adapted to the second elastic member 23 in the circumferential direction, and the second elastic member 23 is clamped in the annular groove 13 to prevent the functional module 2 from sliding in the first direction. In this embodiment, the second elastic member 23 is an O-shaped sealing ring. The hole wall 14 of the connecting hole 12 is provided with an annular groove 13 adapted to the O-shaped sealing ring for accommodating and fixing the O-shaped sealing ring.

[0060] In this embodiment, the second elastic member 23 is introduced and sleeved on the functional module 2, and at the same time, the annular groove 13 adapted to the second elastic member 23 is arranged on the hole wall 14 in the circumferential direction to achieve the fixation of the functional module 2 in the first direction. After the second elastic member 23 is clamped in the annular groove 13, it tightly adheres to the side wall of the groove and abuts against the hole wall 14 by virtue of its elastic property, and the sliding of the functional module 2 in the first direction is prevented by the friction force. Specifically, the friction force generated by the elastic deformation of the O-shaped sealing ring and the tight cooperation with the annular groove 13 prevents the functional module 2 from sliding and falling in the first direction.

[0061] The massage head 21, as shown in Figure 2 and Figure 3 , is fixedly connected with the transmission shaft 29 of the main member 20 and rotates by the driving of the motor 27. The massage head 21 is designed as an interchangeable component, and users can choose different types of massage heads 21 according to their preferences and needs. The optional types of the massage head 21 include a massage ball 30, a brush head 31 or a silica gel head 32, etc. These massage heads 21 have different shapes, materials and functions to meet the diversified needs of users.

[0062] As shown in Figure 6 , the brush head 31 is selected when it is necessary to remove dead skin and dirt.

[0063] As shown in Figure 7 , the massage ball 30 is selected when strong massage is needed.

[0064] As shown in Figure 8 , the silica gel head 32 is selected when gentle cleaning is needed.

[0065] In this embodiment, the water outlet device is provided with an elastic member on the outer side wall of the functional module 2. When the functional module 2 is attached to the connecting hole 12 of the body 1, the elastic member will deform and tightly adhere to the hole wall 14 of the connecting hole 12. This design utilizes the friction force to achieve the stable fixation of the functional module 2 relative to the body 1, so that the functional module 2 can be conveniently and firmly installed on the body 1, and at the same time, it is also convenient for users to disassemble and replace the functional module 2 according to needs, thereby improving the flexibility and practicality of the water outlet device.
