Description

Technical Field

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

[0002] In the field of bathroom equipment, to give products such as shower heads and shower units a massage water function, an impeller is usually installed in the inner cavity of the water outlet device. Through the impeller and its linked water-blocking components, the water circulation can be controlled, thereby causing the water outlet device to produce intermittent jets of water, thus achieving the desired massage effect for the user.

[0003] In current technological fields, water-dispensing devices with massage functions typically employ gear transmission mechanisms to achieve linkage between the impeller and the water-blocking component. However, this gear structure requires extremely high machining precision. Insufficient precision may cause jamming during linkage, resulting in poor movement of the water-blocking component and thus affecting water dispensing and the massage effect. Furthermore, existing water-dispensing devices have a single water spray direction and a limited range of action, which cannot meet the needs of all users. Utility Model Content

[0004] The purpose of this invention is to provide a massage water outlet device that solves the problems existing in the prior art, simplifies the internal linkage mechanism of the product, and provides multi-directional massage water flow.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A massage water dispensing device includes a water inlet assembly and a water outlet assembly rotatably coupled to the water inlet assembly. The water outlet assembly includes a water outlet body, an impeller, and a movable component. The water outlet body has an inlet chamber and two parallel water outlet chambers, as well as at least one water outlet hole. A water passage hole is provided between the inlet chamber and the two water outlet chambers to achieve communication. The water outlet hole communicates with the water outlet chamber. The impeller rotatably engages within the inlet chamber. The movable component reciprocates within the inlet chamber and movably opens and closes the two water passage holes. An eccentric shaft and a movable groove are respectively provided between the opposing surfaces of the impeller and the movable component. The eccentric shaft is inserted into and movably engaged with the inner wall of the movable groove to link the impeller and the movable component.

[0007] The water inlet chamber is provided with an inclined water hole, and the inlet and outlet ends of the inclined water hole are respectively connected to the water inlet assembly and the water inlet chamber; the inclined water hole and the water passage hole are respectively provided on the opposite inner walls of the water inlet chamber, and the impeller and the moving parts are located between the opposite inner walls.

[0008] Preferably, the water outlet body includes an inlet component, a water passage component, and an outlet component. The inlet component and the water passage component enclose each other to form the inlet cavity, and the water passage component and the outlet component enclose each other to form the outlet cavity. The inlet component is provided with the inclined water hole, the water passage component is provided with the water passage hole, and the outlet component is provided with the outlet hole.

[0009] The massage water outlet device further includes a locking device, and the outlet body also includes a screw; the locking device is coaxially arranged with the outlet body and passes through the water inlet assembly, and the screw passes through the impeller and the water inlet in sequence and is threadedly connected to the locking device.

[0010] Preferably, the water inlet component has a rotating groove on the side facing the water inlet assembly, and a positioning groove is provided at the axis of the rotating groove; the water outlet end of the water inlet assembly rotates to fit into the rotating groove, and the end of the locking fastener is inserted into the positioning groove; a sealing gasket is provided between the water outlet end of the water inlet assembly and the bottom wall of the rotating groove, a plurality of first sealing rings are provided between the circumferential surface of the water inlet assembly and the side wall of the rotating groove, and a second sealing ring is provided between the circumferential surface of the locking fastener and the water inlet assembly.

[0011] The length direction of the movable groove is not parallel to the reciprocating movement direction of the movable component.

[0012] The diameter of the eccentric shaft is smaller than the width of the movable groove; the opposite sidewalls at both ends of the movable groove are provided with clearance grooves.

[0013] The bottom wall of the water inlet chamber is provided with a sliding groove, and steps are provided on both sides of the bottom wall of the sliding groove. The movable part slides on the steps to achieve a clearance fit with the bottom wall of the water inlet chamber.

[0014] The distance between the two water passages in the water inlet chamber is greater than the length of the movable part; when the number of water outlets is designed to be more than one, two rows are arranged at equal angles along the length of the water outlet chamber, and the water outlets of the two water outlet chambers are inclined towards each other in the water outlet direction.

[0015] The water inlet assembly is a single unit and is equipped with a handle.

[0016] After adopting the above technical solution, the present invention has the following technical effects:

[0017] (1) Two water outlet chambers are configured within the water outlet body. The connection between these two water outlet chambers and the water inlet chamber is dynamically opened and closed via a moving part driven by an impeller. In this way, when water is filled into the water inlet chamber, water can be periodically supplied to the two water outlet chambers. Whether water is entering from a single water outlet chamber or both water outlet chambers are entering from the same chamber simultaneously, the water outlet direction of the water outlet device will be different. This design allows the massage water outlet device to spray massage water in multiple directions and in a circulating manner to meet the diverse needs of users.

[0018] (2) The impeller and the moving parts are linked by the synergistic effect of the eccentric shaft and the moving groove. When the impeller rotates, the sliding action of the eccentric shaft on the inner wall of the moving groove acts on the moving parts, generating a force that drives them to reciprocate. In this way, the moving parts perform linear reciprocating motion in the water inlet chamber, thereby controlling the opening and closing of the two water passages at a specific frequency.

[0019] (3) The switching frequency of the multi-directional water outlet function of this utility model can be widely adjusted by adjusting parameters such as the distance between the eccentric shaft and the rotating shaft of the impeller, the diameter of the eccentric shaft, the size of the movable groove, the length of the movable part, and the interval of the water passage holes. Compared with the existing gear structure, this design is simpler to implement and has a lower cost.

[0020] (4) The assembly and cooperation of the water inlet component and the water outlet component allows the angle of the water outlet component to be freely adjusted while keeping the angle of the water inlet component relatively fixed, enabling 360° rotation. This allows the water jet to be sprayed in any direction, thereby achieving a more flexible user experience and meeting different massage needs. Attached Figure Description

[0038] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0039] refer to Figure 1-10 As shown, this utility model discloses a massage water outlet device, including a water inlet component 1 and a water outlet component 2 that rotates and cooperates with the water inlet component 1; the water outlet component 2 includes a water outlet body, an impeller 21 and a movable part 22;

[0040] The water outlet body is provided with an inlet chamber 2a and two outlet chambers 2b and 2b' arranged in parallel, as well as at least one outlet hole 251; a water passage hole 241 and 241' are respectively provided between the inlet chamber 2a and the two outlet chambers 2b and 2b' to achieve communication; the outlet hole 251 is connected to the outlet chamber;

[0041] The impeller 21 rotates and is fitted within the water inlet chamber 2a; the movable part 22 reciprocates and is fitted within the water inlet chamber 2a, and movably opens and closes the two water passages 241 and 241'.

[0042] An eccentric shaft 211 and a movable groove 221 are respectively provided between the opposite surfaces of the impeller 21 and the movable part 22. The eccentric shaft 211 is inserted into and movably fitted on the inner wall of the movable groove 221 so that the impeller 21 and the movable part 22 are linked together.

[0043] Through the above solution, this utility model has the following technical effects:

[0044] (1) Two water outlet chambers 2b and 2b' are configured in the water outlet body. The connection between these two water outlet chambers and the water inlet chamber 2a, namely the water passage holes 241 and 241', is dynamically opened and closed by the moving part 22 driven by the impeller 21. In this way, when the water inlet chamber 2a is filled with water, it can periodically supply water to the two water outlet chambers 2b and 2b'. Whether water is supplied to a single water outlet chamber or both water outlet chambers are supplied at the same time, the water outlet direction of the water outlet device will be different. This design allows the massage water outlet device to spray massage water in multiple directions and in a circulating manner to meet the diverse needs of users.

[0045] (2) The impeller 21 and the movable part 22 are linked through the coordinated action of the eccentric shaft 211 and the movable groove 221. When the impeller 21 rotates, the sliding action of the eccentric shaft 211 on the inner wall of the movable groove 221 acts on the movable part 22, generating a force that drives it to reciprocate. In this way, the movable part 22 performs linear reciprocating motion in the water inlet chamber 2a, thereby controlling the opening and closing of the two water passage holes 241 and 241' at a specific frequency.

[0046] (3) The switching frequency of the multi-directional water outlet function of this utility model can be widely adjusted by adjusting parameters such as the distance between the eccentric shaft 211 and the rotating shaft 22 of the impeller 21, the diameter of the eccentric shaft 211, the size of the movable groove 221, the length of the movable part 22, and the spacing of the water passage holes 14. Compared with the existing gear structure, this design is simpler to implement and has a lower cost.

[0047] (4) The assembly and cooperation of the water inlet component 1 and the water outlet component 2 allows the angle of the water outlet component 2 to be freely adjusted while the angle of the water inlet component 1 remains relatively fixed, enabling 360° rotation. This allows the water column to be sprayed in any direction, thereby achieving a more flexible user experience and meeting different massage needs.

[0048] The following shows a specific implementation of the above-mentioned water outlet device.

[0049] The aforementioned water inlet chamber 2a is provided with an inclined water hole 231. The inlet and outlet ends of the inclined water hole 231 are connected to the water inlet assembly 1 and the water inlet chamber 2a, respectively, to realize the water inlet function of the water inlet chamber 2a, and to drive the impeller 21 to rotate through the inclined water flow. In this embodiment, the aforementioned inclined water hole 231 and the water passage holes 241 and 241' are respectively provided on the opposite inner walls of the water inlet chamber 2a, and the impeller 21 and the movable part 22 are located between the opposite inner walls, so that the water flow can flow from the inclined water hole 231 to the water passage holes 241 and 241' without changing the direction too much, thereby reducing the loss of flow velocity.

[0050] Furthermore, the aforementioned water outlet body includes an inlet component 23, a water passage component 24, and an outlet component 25. The inlet component 23 and the water passage component 24 enclose the aforementioned inlet cavity 2a, and the water passage component 24 and the outlet component 25 enclose the aforementioned outlet cavities 2b and 2b'. The inlet component 23 is provided with the aforementioned inclined water hole 231, the water passage component 24 is provided with the aforementioned water passage hole 241, and the outlet component 25 is provided with the aforementioned outlet hole 251. Specifically, the inlet component 23 and the water passage component 24 are each provided with a groove structure on their opposite surfaces for the impeller 21 and the moving part 22 to cooperate. The outlet component 25 and the water passage component 24 are each provided with two parallel groove structures on their opposite surfaces to form two parallel outlet cavities 2b and 2b'.

[0051] Secondly, this utility model also includes a locking fastener 3, and the water outlet body also includes a screw 26. The locking fastener 3 is coaxially arranged with the water outlet body (i.e., the aforementioned water inlet component 23, water passage component 24, and water outlet component 25) and passes through the water inlet assembly 1. The screw 26 passes through the impeller 21 and the water inlet component 23 in sequence and is threadedly connected to the locking fastener 3. In this embodiment, a sealing ring 27 is provided between the circumferential surface of the screw 26 and the impeller 21. Thus, the water outlet component 25 is installed on the water inlet assembly 1 by the cooperation of the screw 26 and the locking fastener 3, thereby achieving relative axial fixation between the water outlet assembly 2 and the water inlet assembly 1. The screw 26 can also serve as the rotating shaft of the impeller 21, making the product assembly more convenient.

[0052] Furthermore, the water inlet component 23 is provided with a rotating groove 232 on the side facing the water inlet assembly 1, and a positioning groove 233 is provided at the axis of the rotating groove 232; the water outlet end of the water inlet assembly 1 rotates to fit into the rotating groove 232, and the end of the locking fastener 3 is inserted into the positioning groove 233; a sealing gasket 4 is provided between the water outlet end of the water inlet assembly 1 and the bottom wall of the rotating groove 232, a plurality of first sealing rings 5 ​​are provided between the peripheral surface of the water inlet assembly 1 and the side wall of the rotating groove 232, and a second sealing ring 6 is provided between the peripheral surface of the locking fastener 3 and the water inlet assembly 1.

[0053] In addition, the water outlet 25 and the water passage 24 are connected by ultrasonic welding to ensure sealing and leak prevention; the water passage 24 is fastened to the water inlet 23 by screws, and a third sealing ring 28 is provided between the two; a cover plate 29 is embedded on the side of the water inlet 23 facing away from the water passage 24 to cover the screws that fasten the water passage 24; a decorative shell 210 is provided on the periphery of the water outlet 25, and the decorative shell 210 can be customized according to user needs, so that the massage water outlet device has various appearance shapes.

[0054] The length direction of the aforementioned movable groove 221 is not parallel to the reciprocating movement direction of the movable component 22. Preferably, in this embodiment, the length direction of the aforementioned movable groove 221 is perpendicular to the reciprocating movement direction of the movable component 22, thereby ensuring that the opening and closing frequencies of the two water passages 241 and 241' remain consistent.

[0055] The diameter of the aforementioned eccentric shaft 211 is smaller than the width of the movable groove 221, so that during the linkage process between the impeller 21 and the movable part 22, when the movable part 22 moves back and forth to the critical point at one end, it will not immediately change direction (because when the diameter is smaller than the width, the eccentric shaft 211 has a certain amount of room to move in the length direction perpendicular to the movable groove 221 without pushing the movable part 22). The speed at which the movable part 22 moves left and right can be adjusted, thereby affecting the frequency of water output and achieving a better water output effect.

[0056] Furthermore, the opposite sidewalls at both ends of the aforementioned movable groove 221 are provided with clearance grooves 222. By providing clearance grooves 222, the path of the eccentric shaft 211 when moving along the sidewall of the movable groove 221 can be increased, thereby adjusting the speed at which the movable part 22 moves left and right.

[0057] Based on actual product design requirements, the aforementioned movable groove 221 can be a groove structure with a closed bottom wall or a through hole structure.

[0058] The bottom wall of the aforementioned water inlet chamber 2a (i.e., on the aforementioned water passage component 24) is provided with a sliding groove 242 for sliding engagement of the movable component 22, thereby guiding the movement of the movable component 22. In this embodiment, the two water passage holes 241 and 241' are symmetrically arranged on the left and right sides of the sliding groove 242 to ensure that the water outlet frequencies of the two water outlet chambers 2b and 2b' remain consistent.

[0059] Furthermore, steps 243 are provided on both sides of the bottom wall of the sliding groove 242, and the movable part 22 slides on the steps 243 to achieve a clearance fit with the bottom wall of the water inlet cavity 2a. The steps 243 can reduce the contact area between the movable part 22 and the inner wall of the water inlet cavity 2a, reduce the friction when the movable part 22 moves back and forth, and make the movement of the movable part 22 smoother. At the same time, although the gap between the movable part 22 and the water inlet cavity 2a may prevent the water passage holes 241 and 241' from being completely closed, the small gap can also prevent the rapid flow of water, ensuring that a certain water inlet cavity 12 is temporarily not filled with water when the movable part 22 moves, that is, it does not affect the functional realization of this utility model. In addition, when there is a high sealing requirement, the reserved gap can also meet the purpose of installing a sealing gasket on the movable part 22.

[0060] The distance between the two water passage holes 241 and 241' in the water inlet chamber 2a is greater than the length of the movable part 22. Therefore, when the movable part 22 moves between the two water passage holes 241 and 241', water can enter both water outlet chambers 2b and 2b'.

[0061] Furthermore, when only one water outlet 251 is designed, the water outlet 251 can simultaneously communicate with two water outlet chambers 2b and 2b', and a separator is provided inside the water outlet 251 to divide the water outlet 251 into two water channels, left and right. In this embodiment, when more than one water outlet 251 is designed, two rows are arranged at equal angles along the length of the water outlet chamber 2b, and the water outlets 251 and 251' of the two water outlet chambers 2b and 2b' are inclined towards each other in the water outlet direction. When water enters the two water outlet chambers 2b and 2b' respectively, their respective water outlets 251 and 251' spray out oblique water flows; while when water enters the two water outlet chambers 2b and 2b' simultaneously, the oblique water flows sprayed out by their respective water outlets 251 and 251' collide with each other and converge, thereby spraying out a straight water flow.

[0062] Normally, the water outlet body will be in the shape of a cuboid. If a larger diameter impeller 21 needs to be designed, a part of the water inlet cavity 2a (i.e., water inlet component 23, water passage component 24) can be designed as a cylinder and protrude to both sides of the cuboid to expand the space for the impeller 21 to be assembled.

[0063] The aforementioned water inlet component 1 is a single unit and is equipped with a handle 11. Therefore, the product of this utility model is actually a handheld shower head. However, this does not mean that the technical solution of this utility model is limited to handheld shower heads.

[0064] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
