Description

Technical Field

[0001] This application relates to the field of bathroom product technology, specifically to a water outlet device and a shower head. Background Technology

[0002] In related technologies, massage spray showerheads generally achieve a massage effect by driving multiple water outlets to oscillate and make the water flow dance. However, in related technologies, the impact force of the water flow on the human body remains basically unchanged, and it is impossible to achieve a kneading massage effect. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a water outlet device for use in a shower head, enabling the water jet from the shower head to achieve a kneading and massaging effect on the human body.

[0004] The present invention also proposes a shower head having the above-mentioned water outlet device.

[0005] According to a first aspect of the present invention, a water outlet device includes: a housing, a water outlet component, and a drive mechanism.

[0006] The housing includes a receiving cavity, an inlet and a plurality of outlets communicating with the receiving cavity, the inlet being for supplying water flow into the receiving cavity, and the outlets extending along a first direction;

[0007] The water outlet is provided in multiple ways, and the multiple water outlets are arranged corresponding to the water outlet holes. Each water outlet has a flow channel, and each flow channel is connected to the receiving cavity and the external space through the corresponding water outlet hole. Each flow channel has a water inlet end, which is used to supply water to enter the flow channel and flow to the external space.

[0008] A drive mechanism, connected to the water outlet component, is used to drive the water outlet component to reciprocate along the first direction;

[0009] A blocking member that is movable among the plurality of water outlets to periodically block the water inlet end of each flow channel.

[0010] The water outlet device according to embodiments of the present invention has at least the following beneficial effects:

[0011] The drive mechanism is connected to the water outlet and is used to drive the water outlet to reciprocate along a first direction. When the water outlet moves toward the first direction, it applies a force toward the water flow in the first direction. When the water outlet moves away from the first direction, it applies a force away from the water flow. Therefore, when the water outlet reciprocates along the first direction, the impact force of the water flow on the human body is different, so that the water flow produces a kneading massage effect on the human body, improving the user's comfort during showering. In addition, the shielding component can periodically block the water outlet of each of the flow channels to reduce the water volume of the blocked flow channels, so that the water volume sprayed by multiple water outlets at the same time is not exactly the same, thereby making the force of the water flow sprayed by multiple water outlets impacting the human body also different, and the force of the water flow sprayed by each water outlet impacting the human body changes periodically, further improving the massage effect.

[0012] According to some embodiments of the present invention, the driving mechanism includes an impeller disposed on the path of water flow from the inlet to the outlet, and the impeller is capable of rotating under the impact of water flow, so that the driving mechanism drives the outlet component to reciprocate.

[0013] According to some embodiments of the present invention, the driving mechanism further includes a first gear, a limiting member, and a supporting member. The first gear is connected to the impeller. The water outlet member further includes a second gear and a main body. The second gear is sleeved on the outside of the main body. The first gear meshes with the second gear.

[0014] The limiting member is disposed on the inner wall of the receiving cavity. The limiting member has a limiting hole that extends along the first direction. The water outlet is movably disposed in the limiting hole. The abutment is disposed on the inner wall of the receiving cavity. The abutment has an abutment surface that is concave and convex along the first direction on the side facing the second direction. The second direction is opposite to the first direction. The abutment surface is distributed around the axis of the limiting hole. The outer wall of the water outlet also has an abutment portion that slides against the abutment surface.

[0015] When the impeller drives the water outlet component to rotate, the supporting part slides along the supporting surface, so that the water outlet component reciprocates along the first direction.

[0016] According to some embodiments of the present invention, a portion of the housing is configured to form the abutment; and / or,

[0017] The housing is partially constructed to form the limiting member, and the water outlet includes the limiting hole.

[0018] According to some embodiments of the present invention, a plurality of abutting portions are evenly distributed on the outer wall of the water outlet, and the abutting portion has a plurality of protrusions on one side facing the second direction. The plurality of protrusions are evenly distributed around the axis of the limiting hole, and the surfaces of the plurality of protrusions are smoothly connected to form the abutting surface. The number of abutting portions is the same as the number of protrusions, and the plurality of abutting portions are evenly distributed along the circumference of the water outlet.

[0019] According to some embodiments of the present invention, the water-facing surface of the impeller blades is parallel to the first direction, and the housing further includes a water divider disposed within the receiving cavity to divide the receiving cavity into a first receiving cavity and a second receiving cavity. The side of the water divider facing the first receiving cavity has a protrusion, and the protrusion has a gap around the first direction with the sidewall of the first receiving cavity. The side of the water divider facing the second receiving cavity has a groove, a portion of which extends to the protrusion. At least a portion of the impeller is located within the groove. The protrusion has an oblique water hole extending perpendicular to the first direction to connect the gap and the groove. The central axis of the oblique water hole is spaced apart from the axis of the impeller and perpendicular to the first direction.

[0020] According to some embodiments of the present invention, the diameter of the flow channel gradually decreases along the first direction.

[0021] According to some embodiments of the present invention, the water outlet element is at least partially disposed within the water outlet hole, the water outlet device further includes a sealing element, the outer wall of the water outlet element also has an annular groove, the sealing element is sleeved in the groove and abuts against the hole wall of the water outlet hole.

[0022] According to some embodiments of the present invention, a plurality of the water outlet components are distributed around the first gear, and the shielding component is connected to the side of the first gear near the impeller so that the shielding component can rotate with the first gear.

[0023] According to some embodiments of the present invention, the angle between the central axis of the flow channel and the first direction is 0 to 45°.

[0024] According to some embodiments of the present invention, the drive mechanism further includes a reduction gear set connected between the impeller and the first gear.

[0025] A shower head according to a second aspect of the present invention includes a body and a water outlet device as described in the first aspect of the present invention.

[0026] The body has a mounting cavity and a shower hole communicating with the mounting cavity, the water outlet device is housed in the mounting cavity, and the water outlet is located at the shower hole.

[0027] The shower head according to an embodiment of the present invention has at least the following beneficial effects:

[0028] The water outlet device according to the first aspect embodiment has a drive mechanism connected to the water outlet component, which drives the water outlet component to reciprocate along a first direction. When the water outlet component moves toward the first direction, it applies a force toward the water flow in the first direction. When the water outlet component moves away from the first direction, it applies a force away from the water flow. Therefore, the impact force of the water flow on the human body is different when the water outlet component reciprocates along the first direction, so that the water flow produces a kneading massage effect on the human body, improving the user's comfort during showering. In addition, the blocking component can periodically block the water outlet ends of each of the flow channels to reduce the water volume of the blocked flow channels, so that the water volume sprayed by multiple water outlets at the same time is not exactly the same. This results in different impact forces of the water flow sprayed by multiple water outlets on the human body, and the periodic change in the impact force of the water flow sprayed by each water outlet on the human body further improves the massage effect.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0049] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0050] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0051] Figure 1 This is a schematic diagram of the structure of a water outlet device according to an embodiment of the present invention. Figure 2 for Figure 1 The sectional view, see reference Figure 1 and Figure 2 The water outlet device according to the first aspect embodiment includes: a housing 100, a drive mechanism 200, a water outlet component 300, and a shielding component 500.

[0052] The housing 100 can be made of a metal that is not easy to rust, such as aluminum alloy, or it can be made of non-metallic materials such as resin or rubber. The interior of the housing 100 has a receiving cavity 110, and a water inlet 120 and multiple water outlets 130 communicating with the receiving cavity 110. The water inlet 120 is used to supply water flow into the receiving cavity 110, and the water outlets 130 extend along a first direction. Multiple water outlets 300 are provided in the receiving cavity 110, and the multiple water outlets 300 are correspondingly arranged with the multiple water outlets 130. The water outlets 300 have flow channels 310, and the flow channels 310 of each water outlet 300 are connected to the receiving cavity 110 and the external space through the corresponding water outlets 130. The water outlets 130 also have water inlets 350, which are used to supply water flow into the flow channels 310 and flow to the external space. The drive mechanism 200 is disposed inside or outside the housing 100, and at least partially located within the receiving cavity 110 and connected to the water outlet 300, for driving the water outlet 300 to reciprocate along a first direction. When the water outlet 300 moves toward the first direction, it applies a force toward the water flow in the first direction, increasing the force of the water flow impacting the human body. When the water outlet 300 moves away from the first direction, it applies a force away from the first direction, reducing the force of the water flow impacting the human body. Therefore, as the water outlet 300 reciprocates along the first direction, the impact force of the water flow on the human body changes periodically, so that the water flow produces a kneading massage effect on the human body, improving the user's comfort during showering.

[0053] The blocking member 500 is connected to the drive mechanism 200, or an additional drive device is provided to drive the blocking member 500. The blocking member 500 can move among multiple water outlet members 300 so that the blocking member 500 periodically blocks the water inlet end 350. When the blocking member 500 blocks the water end of the inlet channel 310, it can prevent water from entering the blocked channel 310, thereby reducing the amount of water flowing into the channel 310, reducing the impact force of the water flow on the human body, or isolating the water flow, so that the water outlet members 300 spray water droplets in a pulse. This makes the amount of water sprayed by multiple water outlet members 300 at the same time not exactly the same, so that the force of the water flow sprayed by multiple water outlet members 300 impacting the human body is also different, and the force of the water flow sprayed by each water outlet member 300 impacting the human body changes periodically, further improving the massage effect.

[0054] Furthermore, the housing 100 can be formed by an upper housing 140 and a lower housing 150 connected to each other. The upper housing 140 and the lower housing 150 can be connected by a detachable connection method, such as a threaded connection or a snap-fit ​​connection, which facilitates the maintenance and replacement of internal parts of the water outlet device. Further, to improve the sealing performance of the housing 100, a sealing ring 160 can be provided between the upper housing 140 and the lower housing 150, or sealant can be applied to prevent water leakage from the housing 100.

[0055] Reference Figure 2 and Figure 3 , Figure 3 for Figure 1 The exploded view shows that, based on the above embodiment, the drive mechanism 200 includes an impeller 210. The impeller 210 is disposed within the receiving cavity 110 and located on the path of water flow from the inlet hole 120 to the outlet hole 130. The impeller 210 can rotate under the impact of the water flow, thereby driving the water outlet component 300 to reciprocate. It can be understood that this embodiment uses water flow as a power source, eliminating the need for other drive devices such as motors and hydraulic cylinders, resulting in a simple structure and lower cost.

[0056] For example, the drive mechanism 200 is equipped with a cam, which is connected to the impeller 210. The side of the cam is slidably connected to the water outlet 300, and the axes of both the impeller 210 and the cam are perpendicular to the first direction. When water flows and impacts the impeller 210, the impeller 210 drives the cam to rotate, and the cam drives the water outlet 300 to reciprocate along the first direction. Alternatively, please refer to... Figures 2 to 5 , Figure 4 for Figure 2 Enlarged view of region A in the middle. Figure 5 for Figure 3 In some embodiments, the drive mechanism 200 further includes a first gear 220, a limiting member 260, and a supporting member 250 (e.g., ...). Figure 3 and Figure 4A limiting member 260 is disposed on the inner wall of the receiving cavity 110. The limiting member 260 has a limiting hole 261 extending along a first direction. The water outlet member 300 is movably disposed within the limiting hole 261 to restrict the position of the water outlet member 300, so that the water outlet member 300 can only rotate and move within the limiting hole 261. A supporting member 250 is disposed on the inner wall of the receiving cavity 110. The side of the supporting member 250 facing the second direction (the second direction is opposite to the first direction) has a supporting surface 251 that is concave and convex along the first direction, and the supporting surface 251 is distributed around the axis of the limiting hole 261. The outer wall of the water outlet member 300 also has a supporting portion 360, which slides against the supporting surface 251 (e.g., Figure 4 and Figure 5 (As shown). The first gear 220 is connected to the impeller 210 so that the first gear 220 can rotate with the impeller 210. The water outlet component 300 also includes a second gear 330 and a main body 320, with the second gear 330 sleeved on the outside of the main body 320 (as shown). Figure 5 As shown, the second gear 330 can be integrally formed with the main body 320 to simplify the assembly process. The first gear 220 meshes with the second gear 330, so when the first gear 220 rotates with the impeller 210, the first gear 220 can drive the second gear 330 to rotate. This causes the supporting portion 360 of the water outlet 300 to slide along the supporting surface 251. Since the first supporting surface 251 undulates along the first direction, it can reciprocate along the first direction during the continuous rotation of the water outlet 300.

[0057] Reference Figure 2 and Figure 4 Based on the above embodiments, a portion of the housing 100 is configured to form a retaining member 250, for example, as... Figure 4 As shown, the wall of the water outlet 130 of the housing 100 has a radially protruding annular boss, which forms the abutment 250 of the drive mechanism 200. It is understood that by partially forming the abutment 250 of the drive mechanism 200 within the housing 100, the number of parts in the water outlet device can be reduced, thereby simplifying the manufacturing process (e.g., saving the processing of the connection structure between the abutment 250 and the housing 100) and the assembly process, thus saving manufacturing costs. For example, if the housing 100 is injection molded, a mold cavity forming the annular boss can be provided at the corresponding position in the mold during mold opening, allowing the abutment 250 of the drive mechanism 200 to be formed during the molding process of the housing 100 without the need for additional processing, thus saving manufacturing costs.

[0058] Reference Figure 2 and Figure 4In some embodiments, a portion of the housing 100 is configured to form a limiting member 260, and the water outlet 130 includes a limiting hole 261, with a portion of the water outlet 300 located within the water outlet 130. Its beneficial effects are similar to those of the aforementioned partial configuration of the housing 100 to form the supporting member 250, and will not be repeated here. Furthermore, in some embodiments, both the supporting member 250 and the limiting member 260 are partially formed from the housing 100.

[0059] Reference Figure 3 , Figures 5 to 7 , Figure 6 This is a sectional view of the lower shell as shown in Figure 3. Figure 7 for Figure 6 An enlarged view of region B shows that, in some embodiments, the outer wall of the water outlet 300 has multiple abutment portions 360 evenly distributed (e.g., Figure 5 As shown), the abutment 250 has a plurality of protrusions 252 on the side facing the second direction. The plurality of protrusions 252 are evenly distributed around the axis of the limiting hole, and the surfaces of the plurality of protrusions 252 are smoothly connected to form an abutment surface 251 (as shown). Figure 7 As shown, the number of abutment portions 360 is the same as the number of protrusions 252, so that the abutment portions 360 correspond one-to-one with the protrusions 172. Therefore, during the rotation of the water outlet 300, the height of each abutment portion 360 is consistent in the first direction, that is, each abutment portion 360 is located at the same position of the corresponding protrusion 252, so that the axis of the water outlet 300 remains parallel to the axis of the limiting hole 261 during the rotation, improving the stability of the water outlet 300, preventing the outer surface of the water outlet 300 from colliding with the inner wall of the limiting hole 261 and generating large noise, and reducing the wear between the outer wall of the water outlet 300 and the inner wall of the limiting hole 261, thereby increasing the service life of the water outlet device of this embodiment.

[0060] Reference Figures 8 to 10 , Figure 8 This is a cross-sectional view of a water outlet device according to another embodiment of the present invention. Figure 9 for Figure 8 Sectional view at CC, Figure 10 for Figure 9 Structural view of the impeller. In some embodiments, the water-facing surface 2112 of the blades 211 of the impeller 210 is parallel to a first direction (e.g., Figure 10 As shown), the housing 100 also includes a water distribution element 170 (as shown). Figure 8As shown), a water divider 170 is disposed within the receiving cavity 110 to divide the receiving cavity 110 into a first receiving cavity 111 and a second receiving cavity 112. The side of the water divider 170 facing the first receiving cavity 111 has a protrusion 172, and the protrusion 172 has a gap around the sidewall of the first receiving cavity 111 in a first direction. The side of the water divider 170 facing the second receiving cavity 112 has a groove 173, a portion of which extends to the protrusion 172. The protrusion 172 also has an oblique water hole 171 extending perpendicular to the first direction (e.g., ...). Figure 9 As shown, the inclined water hole 171 connects the gap and the groove 173. The central axis of the inclined water hole 171 is spaced apart from the axis of the impeller 210, and at least a portion of the impeller 210 is located within the groove 173. During use, after the water flows through the inclined water hole 171 to the second receiving cavity 112, the thrust formed by the water flow on the water-facing surface 2112 is perpendicular to the water-facing surface 2112, which allows the impeller 210 to receive greater torque, increasing the driving force of the drive mechanism 200. This allows the drive mechanism 200 to more easily drive more water outlets 300, enabling the user to enjoy multi-point massage during showering.

[0061] like Figure 4 As shown, in some embodiments, the diameter of the flow channel 310 of the water outlet 300 gradually decreases along the first direction. Therefore, when the water outlet 300 moves toward the second direction, the force exerted by the water outlet 300 on the water is greater, which makes the difference between the impact force of the water flow on the human body when the water outlet 300 moves toward the first direction and toward the second direction greater, making the kneading and massage effect on the human body more obvious and improving the user's comfort.

[0062] Reference Figure 2 and Figure 4In some embodiments, the water outlet component 300 is partially disposed within the water outlet hole 130. The wall of the water outlet hole 130 provides guidance and limiting for the water outlet component 300, improving its stability during movement. The water outlet device also includes a sealing component 400. The outer wall of the water outlet component 300 has an annular groove 340. The sealing component 400 is fitted into the groove 340 and abuts against the wall of the water outlet hole 130 to improve the sealing between the water outlet component 300 and the housing 100, preventing leakage from the housing 100. The groove 340 is provided in the water outlet component 300 to prevent the sealing component 400 from falling off during movement, ensuring its reliability. Furthermore, the seal 400 includes a first sealing portion 410 and a second sealing portion 420. One end of the first sealing portion 410 is connected to one end of the second sealing portion 420 to define a V-groove 430. The opposing surfaces of the first sealing portion 410 and the second sealing portion 420 respectively abut against the inner wall of the water outlet 130 and the water outlet component 300. As water flows from the water inlet 120 to the water outlet 130, the water flow fills the V-groove 430, compressing the first sealing portion 410 and the second sealing portion 420, making the first sealing portion 410 and the second sealing portion 420 more tightly adhered to the wall of the water outlet 130 and the outer wall of the water outlet component 300, thereby improving the sealing performance.

[0063] In some embodiments, multiple water outlet components 300 are distributed around the first gear 220, and a shielding component 500 is connected to the side of the first gear 220 near the impeller 210, so that the shielding component 500 can rotate with the first gear 220 without the need for an additional drive device, making the structure of the water outlet device in this embodiment simpler and the manufacturing cost lower.

[0064] Furthermore, in some embodiments, the shield 500 can be constructed from the planet carrier 233 in the reduction gear set 230 as described above (e.g., Figure 2 and Figure 3 As shown, the planetary carrier 233 has a hollow area and a solid area. When the solid area rotates to the corresponding water outlet 300, it blocks the water inlet 350 of the water outlet 300. Therefore, the reduction gear set 230 can periodically block the flow channel 310 while achieving speed reduction, so that the water outlet device of this embodiment does not need to be equipped with other parts, making the structure simpler and the cost lower.

[0065] Reference Figure 4In some embodiments, the angle α between the central axis of the flow channel 310 and the first direction is 0 to 45°. When the angle α between the central axis of the flow channel 310 and the first direction is equal to 0, the water flows towards the human body along the first direction, resulting in the same direction of force on the human body. When the angle α between the central axis of the flow channel 310 and the first direction is greater than 0, the direction of the flow channel 310 changes periodically during the rotation of the water outlet 300, causing the water flow to dance, thereby increasing the spray range of the water flow, increasing the massage range of the human body, and improving the user experience. In addition, during the dance of the water flow, the angle at which the water flow sprays towards the human body is different within one cycle, allowing the human body to receive massage effects from different angles of force, thereby further improving the user experience.

[0066] Reference Figure 3 In some embodiments, the drive mechanism 200 further includes a reduction gear set 230, which is connected between the impeller 210 and the first gear 220. For example, the reduction gear set 230 is a planetary reduction gear set 230, which includes a sun gear 231, planet gears 232, and a planet carrier 233. The drive mechanism 200 also includes a connecting shaft 240, which is connected to the inner wall of the receiving cavity 110. The sun gear 231 is fixedly connected to the impeller 210 and rotatably mounted on the connecting shaft 240. The sun gear 231 and the impeller 210 can be integrally formed to simplify the manufacturing process, or they can be formed separately and connected by fasteners. Therefore, different materials can be selected to make the impeller 210 and the sun gear 231 according to their usage requirements, so that the impeller 210 and the sun gear 231 can save manufacturing costs while meeting the usage requirements. The planetary carrier 233 is rotatably mounted on the connecting shaft 240 and is located on the side of the sun gear 231 away from the impeller 210. Planetary gears 232 are connected to the side of the sun gear 231 facing the sun gear 231 and are located off-axis of the sun gear 231, meshing with it. Typically, there are three planetary gears 232, evenly distributed around the sun gear 231. The first gear 220 is fixedly connected to the side of the planetary carrier 233 away from the planetary gears 232. The impeller 210 drives the first gear 220 to rotate via the reduction gear set 230. This increases the torque on the first gear 220, thereby increasing the torque on the second gear 330, enabling the drive mechanism 200 to drive more water outlet components 300. Simultaneously, it prevents the drive mechanism 200 from jamming during movement, ensuring the normal operation of the water outlet components 300. On the other hand, when the water outlet 300 moves and dispenses water, the reduction gear set 230 can reduce the rotation speed of the water outlet 300, so that the rotation speed of the water outlet 300 is within a reasonable range. Therefore, the oscillation trajectory of the water flow can be seen more intuitively, resulting in a better massage effect.

[0067] The shower head according to the second aspect embodiment includes a body and a water outlet device according to the first aspect embodiment. The body has a mounting cavity and a shower hole communicating with the mounting cavity. The water outlet device is housed within the mounting cavity, and a water outlet 130 is located at the shower hole. A drive mechanism 200 of the water outlet device is used to drive the water outlet component 300 to reciprocate along a first direction. The drive mechanism 200 is connected to the water outlet component 300 and is used to drive the water outlet component 300 to reciprocate along the first direction. When the water outlet component 300 moves in the first direction, it applies a force to the water flow in the first direction, increasing the force of the water flow impacting the human body. When the water outlet component moves in a second direction, it applies a force to the water flow in the second direction, reducing the force of the water flow impacting the human body. Therefore, as the water outlet component 300 reciprocates along the first direction, the impact force of the water flow on the human body changes periodically, so that the water flow produces a kneading massage effect on the human body, improving the user's comfort during showering. Furthermore, the blocking member 500 of the water outlet device can move among multiple water outlet members 300, so that the blocking member 500 periodically blocks the water inlet end 350. When the blocking member 500 blocks the water end of the inlet channel 310, it can prevent water from entering the blocked channel 310, thereby reducing the amount of water flowing into the channel 310, reducing the impact force of the water flow on the human body, or isolating the water flow, so that the water outlet members 300 spray water droplets in a pulse. This makes the amount of water sprayed by multiple water outlet members 300 at the same time not exactly the same, so that the force of the water flow sprayed by multiple water outlet members 300 impacting the human body is also different, and the force of the water flow sprayed by each water outlet member 300 impacting the human body changes periodically, further improving the massage effect.

[0068] It should be noted that since the shower head in this embodiment adopts all the technical solutions of the water outlet device of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment, which will not be repeated here.
