[0001] The utility model relates to the technical field of bathroom equipment, in particular to a water outlet device and a shower. Background Art

[0002] In the bathroom field, in order to achieve the massage water function, shower heads, shower heads and other bathroom equipment usually need to set an impeller in the inner cavity of the water outlet device, and realize the circulating water path on-off function through the impeller itself or the water baffle linked thereto, so that the water flow output by the water outlet device is in an intermittent jet state, thereby achieving a massage effect on the user.

[0003] In the prior art, the water outlet device with massage function usually relies on the transmission of gear structure to realize the linkage between the impeller and the corresponding water baffle. The processing accuracy of the gear structure is relatively high, otherwise it may cause jamming during the linkage process, and the water baffle may not move smoothly enough, affecting the water outlet effect and massage effect; moreover, the water splash direction of the existing water outlet device is relatively single and the range of action is small, which cannot meet the needs of some users. Utility Model Content

[0004] The purpose of the utility model is to provide a water outlet device and a shower, which solve the problems existing in the prior art, can simplify the internal linkage structure of the product, and output massage water in multiple directions.

[0005] In order to achieve the above objectives, one of the solutions of the present invention is:

[0006] A water outlet device comprises a shell, an impeller and a movable part; a water inlet chamber and at least two water outlet chambers arranged in parallel, and at least one water outlet hole are provided in the shell; a water through hole is respectively provided between the water inlet chamber and each water outlet chamber to achieve communication; the water outlet hole is communicated with each water outlet chamber at the same time, and a diversion part is provided in the water outlet hole, and the diversion part divides the water outlet hole into a plurality of water paths respectively communicated with each water outlet chamber; the impeller rotatably fits in the water inlet chamber; the movable part reciprocates and fits in the water inlet chamber, and movably opens and closes each water through hole; an eccentric shaft and a strip hole are respectively provided between the opposing surfaces of the impeller and the movable part, and the eccentric shaft is inserted into and movably fits in the strip hole to enable the impeller and the movable part to be linked.

[0007] The number of the water outlet cavities is designed to be two; the number of the water outlet holes is at least two, and they are arranged at equal intervals along the reciprocating movement direction of the movable part.

[0008] The water inlet cavity is provided with a water inlet hole, and the water inlet hole is communicated with the water inlet cavity.

[0009] Preferably, the water outlet device also includes a water guide plate arranged in the water inlet chamber and opposite to the water inlet hole, and a plurality of inclined water holes are provided on the water guide plate; the water guide plate is provided with an axial hole, and the impeller is provided with a rotating shaft rotatably fitted in the axial hole, and axial limitation is achieved by a bolt; the water guide plate is provided with a pressure plate on the side facing away from the impeller, and the pressure plate covers the periphery of the axial hole, and the bolt passes through the pressure plate and is threadedly connected to the rotating shaft; a self-lubricating gasket is provided at the end of the axial hole facing the impeller, and the rotating shaft is passed through the self-lubricating gasket.

[0010] The length direction of the strip-shaped hole is perpendicular to the reciprocating direction of the movable member.

[0011] The diameter of the eccentric shaft is smaller than the width of the strip-shaped hole.

[0012] First inclined surfaces are symmetrically provided on both sides of the diversion portion, and second inclined surfaces opposite to the first inclined surfaces are provided on both sides of the water outlet.

[0013] A pair of parallel guide flanges are provided on the inner wall of the water inlet chamber on which the water hole is provided, and the movable part slides and fits between the pair of guide flanges; steps are provided between the opposite side walls of the guide flanges, and the movable part slides and fits on the steps to achieve a clearance fit with the inner wall of the water inlet chamber.

[0014] Preferably, both ends of the movable part are provided with sliders that slide between the guide flanges, and the height of the sliders is lower than the main part of the movable part provided with the strip hole, and the main part is located on the surface of the guide flange; the sliders realize the movable opening and closing of the corresponding water holes as the movable part moves back and forth.

[0015] The second solution of the utility model is:

[0016] A shower comprises the water outlet device.

[0017] After adopting the above technical solution, the utility model has the following technical effects:

[0018] (1) The utility model can periodically supply water to the two water outlet chambers after water is introduced into the water inlet chamber. When water is introduced into only one of the water outlet chambers or both water outlet chambers simultaneously, the water outlet direction of the water outlet device is different, thereby achieving the effect of spraying massage water in multiple directions and in a cyclic manner.

[0019] (2) The impeller and the movable part are linked by the cooperation of the eccentric shaft and the strip hole. When the impeller rotates, the eccentric shaft can move in the strip hole so that the movable part is driven to move back and forth, thereby moving back and forth in a straight line in the water inlet chamber, thereby realizing the opening and closing of the two water holes at a certain frequency.

[0020] (3) The switching frequency of the multi-directional water outlet function of the utility model can be adjusted by adjusting multiple parameters such as the distance between the eccentric shaft of the impeller and its axis, the diameter of the eccentric shaft, the length and width of the strip hole, the length of the movable part, the spacing of the water holes, etc. The adjustment range is wide, and compared with the existing gear structure, it is easier to implement in product design and has lower cost.

[0037] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0038] refer to Figure 1-8 As shown, the utility model discloses a water outlet device, comprising a housing 1, an impeller 2 and a movable part 3;

[0039] The housing 1 is provided with a water inlet chamber 11 and two parallel water outlet chambers 12 and 12', and at least one water outlet hole 13; a water hole 14 and 14' are respectively provided between the water inlet chamber 11 and the two water outlet chambers 12 and 12' to achieve communication; the water outlet hole 13 is simultaneously connected to the two water outlet chambers 12, and a diverter 15 is provided in the water outlet hole 13, which divides the water outlet hole 13 into two water paths respectively connected to the two water outlet chambers 12 and 12';

[0040] The impeller 2 rotates and fits in the water inlet chamber 11; the movable member 3 reciprocates and fits in the water inlet chamber 11, and movably opens and closes the two water holes 14, 14';

[0041] An eccentric shaft 21 and a strip hole 31 are respectively provided between the opposing surfaces of the impeller 2 and the movable member 3 . The eccentric shaft 21 is inserted into and movably fitted in the strip hole 31 to enable the impeller 2 and the movable member 3 to be linked.

[0042] Through the above solution, the utility model sets two water outlet chambers 12 in the housing 1, and the communication between the two water outlet chambers 12 and the water inlet chamber 11 (water holes 14, 14') is opened and closed by the movable member 3 driven by the impeller 2, so that after the water inlet chamber 11 is filled with water, water can be periodically supplied to the two water outlet chambers 12, 12'. Figure 8When water is introduced into only one of the water outlet chambers 12 or into both water outlet chambers 12 at the same time, the water outlet direction of the water outlet device is different, thereby realizing the spraying of massage water in multiple directions and in a cyclic manner; at the same time, the impeller 2 and the movable part 3 are linked by the cooperation of the eccentric shaft 21 and the strip hole 31. When the impeller 2 rotates, the movement of the eccentric shaft 21 in the strip hole 31 causes the movable part 3 to be subjected to a force driving its reciprocating movement, thereby performing a linear reciprocating movement in the water inlet chamber 11, thereby realizing the movable opening and closing of the two water holes 14, 14' at a certain frequency; the switching frequency of the multi-directional water outlet function of the utility model can be adjusted by adjusting multiple parameters such as the distance between the eccentric shaft 21 of the impeller 2 and its axis (i.e., the rotating shaft 22 described below), the diameter of the eccentric shaft 21, the length and width of the strip hole 31, the length of the movable part 3, the interval between the water holes 14, etc., with a wide adjustment range, and compared with the existing gear structure, it is easier to implement in product design and has lower cost.

[0043] The specific implementation of the water outlet device is shown below.

[0044] The water inlet chamber 11 is provided with a water inlet hole 16, which is in communication with the water inlet chamber 11 and is used to connect to the water supply end of a water outlet device, such as a water pipe, to realize the water supply function of the water inlet chamber 11. In this embodiment, the water inlet hole 16 and the water passage holes 14 and 14' are respectively disposed on opposing inner walls of the water inlet chamber 11, with the impeller 2 and the movable member 3 positioned between the opposing inner walls. This minimizes the loss of flow velocity by ensuring that the water flow does not significantly change direction from the water inlet hole 16 to the water passage holes 14 and 14'.

[0045] Furthermore, the present invention also includes a water guide plate 4 arranged in the water inlet chamber 11 and opposite to the water inlet hole 16. The water guide plate 4 is provided with a plurality of spiral or inclined water holes 41 arranged at equal angles around its axis, so that the water flowing into the water inlet hole 16 flows toward the blades of the impeller 2 in an inclined direction, thereby generating thrust on the impeller 2 and causing it to rotate.

[0046] Secondly, the water guide plate 4 is provided with an axial hole 42, and the impeller 2 is provided with a rotating shaft 22 that rotatably fits within the axial hole 42 and is axially limited by a bolt 5. Thus, the impeller 2 can be installed in the water inlet chamber 11, and the impeller 2 rotates through the engagement of the rotating shaft 22 with the axial hole 42 and is limited in position by the bolt 5.

[0047] Furthermore, a pressure plate 6 is provided on the side of the water guide plate 4 facing away from the impeller 2, and the pressure plate 6 covers the periphery of the shaft hole 42. The bolt 5 passes through the pressure plate 6 and is threadedly connected to the rotating shaft 22. A self-lubricating gasket 7 is provided on the end of the shaft hole 42 facing the impeller 2, and the rotating shaft 22 passes through the self-lubricating gasket 7. The self-lubricating gasket 7 acts as a bearing between the water guide plate 4 and the impeller 2, making the rotation of the impeller 2 smoother.

[0048] The length direction of the strip hole 31 is not parallel to the reciprocating direction of the movable member 3. Preferably, in this embodiment, the length direction of the strip hole 31 is perpendicular to the reciprocating direction of the movable member 3, thereby maintaining the same opening and closing frequency of the two water holes 14, 14'.

[0049] The diameter of the eccentric shaft 21 is smaller than the width of the strip hole 31, so that during the linkage process between the impeller 2 and the movable part 3, when the movable part 3 moves back and forth to the critical point at one end thereof, the direction will not be reversed immediately (because when the diameter is smaller than the width, the eccentric shaft 21 has a certain movement space in the length direction perpendicular to the strip hole 31 without pushing the movable part 3). The speed of the movable part 3 moving left and right can be adjusted, thereby affecting the frequency of water discharge and achieving a better water discharge effect.

[0050] The two sides of the diversion portion 15 are symmetrically provided with first inclined surfaces 151, and the two sides of the water outlet 13 are provided with second inclined surfaces 131 opposite to the first inclined surfaces 151. The inclination direction of the first inclined surface 151 and the second inclined surface 131 can guide the water outlet direction of the corresponding water outlet cavity 12: Figure 8 Due to the inclined surface of diverter 15, when water enters the left outlet chamber 12, the water flow from the outlet device tilts to the right. When water enters the right outlet chamber 12', the water flow from the outlet device tilts to the left. When water enters both outlet chambers 12 and 12', the water flow from the outlet device forms a straight stream due to the counteraction of the two water flows. By designing an inclined surface between the outlet hole 13 and the diverter 15 to guide the water flow, structural design and product production are easier to implement, and the processing difficulty is reduced.

[0051] When there are multiple water outlet holes 13, they are arranged at equal intervals along the reciprocating direction of the movable member 3. Generally, the housing 1 is in the shape of a rectangular parallelepiped. If a larger diameter impeller 2 is required, a portion of the water inlet cavity 11 can be designed as a cylindrical shape and protrude to both sides of the rectangular parallelepiped (see Figure 1 ), thereby expanding the space for assembling the impeller 2.

[0052] A pair of parallel guide flanges 17 are provided on the inner wall of the water inlet chamber 11, where the water hole 14 is provided. The movable member 3 is slidably fitted between the pair of guide flanges 17 to enable the movable member 3 to reciprocate within the water inlet chamber 11. The guide flanges 17 guide the reciprocating movement of the movable member 3, ensuring its stable function.

[0053] Furthermore, steps 171 are provided between the opposing side walls of the guide flange 17, and the movable member 3 slides on the steps 171 to achieve clearance fit with the inner wall of the water inlet chamber 11. The steps 171 can reduce the contact area between the movable member 3 and the inner wall of the water inlet chamber 11, reducing the friction force during the reciprocating movement of the movable member 3, thereby making the movement of the movable member 3 smoother. At the same time, although the gap between the movable member 3 and the water inlet chamber 11 may prevent the water holes 14 and 14' from being completely closed, the smaller gap can also prevent water from flowing, ensuring that a certain water inlet chamber 12 is temporarily blocked from water when the movable member 3 moves, that is, it does not affect the functional realization of the present invention. In addition, when there is a high sealing requirement, the reserved gap can also meet the purpose of installing a sealing cushion on the movable member 3.

[0054] At the same time, sliders 32 are provided at both ends of the movable member 3, which slidably fit between the guide flanges 17. The height of the sliders 32 is lower than the main portion 33 of the movable member 3, where the strip-shaped holes 31 are located. Specifically, the main portion 33 is located on the surface of the guide flanges 17. The sliders 32 open and close the corresponding water holes 14, 14' as the movable member 3 reciprocates. The length of the main portion 33 can be designed based on the length of the strip-shaped holes 31, and is not limited by the spacing of the guide flanges 17.

[0055] The strip-shaped hole 31 may be a countersunk hole or a through hole.

[0056] In this embodiment, the above-mentioned shell 1 includes a water outlet plate 1a, a front cover 1b, a rear cover 1c and a water inlet joint 1d that are separately connected; the above-mentioned water outlet chamber 12 is surrounded by the water outlet plate 1a and the front cover 1b; the above-mentioned water inlet chamber 11 is jointly surrounded by the front cover 1b, the rear cover 1c and the water inlet joint 1d; the water inlet hole 16 is provided on the water inlet joint 1d, the water outlet hole 13 is provided on the water outlet plate 1a, and the water hole 14 and the guide flange 17 are provided on the front cover 1b.

[0057] In other embodiments, when there are more than two water outlet cavities 12, for example, three water outlet cavities 12 are provided in the shell 1, the three water outlet cavities 12 can be arranged at equal angles around the same center line, and only one water outlet hole 13 is designed and provided at the center line, so that it can be connected to each water outlet cavity 12 at the same time.

[0058] In addition, the present invention also discloses a shower, which includes the above-mentioned water outlet device, and thus also has the technical effects corresponding to the water outlet device.

[0059] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
