This application claims priority to Chinese patent application number 201911025608.9, filed on Oct. 25, 2019. Chinese patent application number 201911025608.9 is incorporated herein by reference.
The present disclosure relates to a water outlet mechanism, and in particular relates to a water outlet device for different water sprays from the same nozzle.
Water outlet devices comprise a water outlet portion, and the water outlet portion comprises a water outlet nozzle. The water outlet nozzle has a water inlet and a water outlet, and the water outlet only discharges a single type of water spray (e.g., a single function water outlet, such as a shower water spray on the existing market). To solve the above deficiencies, there are two solutions.
The first solution, such as described in CN208661438U, CN109894289A in the Chinese patent database, includes a water outlet nozzle that has a water inlet and a water outlet, and the water outlet device is also disposed with a movable portion, an operating portion, and a driving mechanism. The driving mechanism is operatively connected to the movable portion and drives the movable portion to move cyclically. The movable portion is movably disposed in a fixed portion and comprises a movable plate and a plurality of convex portions convexly arranged on the movable plate. The convex portions are inserted into the water outlet nozzle, and there is a gap between the water outlet nozzle and the convex portions. The operating portion drives the movable portion to move at least between a first position and a second position. Different water sprays are discharged when the movable portion is in the first position and the second position. The water spray pattern is simple.
The second solution, such as described in NZ745204A, includes a water outlet nozzle that has two water inlets and one water outlet. One water inlet (i.e., an inner port of the water outlet nozzle) flows in the same direction as the water outlet, and the other water inlet is located on a peripheral wall of the water outlet. By controlling water flowing into the two water inlets, the water outlet of the water outlet nozzle can be controlled to discharge different water sprays.

The cover 1 comprises a plurality of water outlet nozzles 11. A water outlet nozzle 11 (i.e., each of the plurality of water outlet nozzles 11 or a single water outlet nozzle 11 of the plurality of water outlet nozzles 11) comprises a water outlet 111, a first water inlet 112, and a second water inlet 113. A flow direction of the first water inlet 112 extends along a direction tangent to the water outlet nozzle 11 to enable the water from the first water inlet 112 to flow into the water outlet nozzle 11 to generate a vortex. A flow direction of the second water inlet 113 intersects with an axial direction of the water outlet nozzle 11. For example, where a flow direction of the water outlet 111 downwardly extends along the axial direction of the water outlet nozzle 11, the flow directions of the first water inlet 112 and the second water inlet 113 are horizontally disposed. That is, a plane disposed with the flow directions of the first water inlet 112 and the second water inlet 113 is perpendicular to the axial direction of the water outlet nozzle 11. Thus, the flow directions of the first water inlet 112 and the second water inlet 113 are not parallel to the flow direction of the water outlet 111. In this embodiment, the flow directions of the first water inlet 112 and the second water inlet 113 intersect, a bottom surface of the first water inlet 112 is lower than a bottom surface of the second water inlet 113, and a linear extension of the flow direction of the first water inlet 112 is disposed on a front side (i.e., a lower side) of the second water inlet 113.

An end surface of the protruding portion 115 is concave to define a groove, which is in communication with the inner opening of the water outlet nozzle 11. The groove defines the second water inlet 113. The cover plate body 2 is hermetically connected to and covers an inner end surface of the surrounding wall 114, and a lower opening of the water passing hole 21 is disposed on an upper side of the groove. The first water inlet 112 is disposed at a connection position of the curved wall 117 and the protruding portion 115.
The water divider 3 is hermetically and fixedly connected to the fixed base 4 to define a water outlet chamber 31, and the water inlet passage 5 is in communication with the water outlet chamber 31.

The first water dividing chamber 15 and the second water dividing chamber 16 are respectively in communication with the first water inlet 112 and the second water inlet 113 to control a water inlet condition of each of the first water inlet 112 and the second water inlet 113. The water inlet condition comprises a flow volume and whether the water is flowing or not flowing, and the water inlet condition of each of the first water inlet 112 and the second water inlet 113 are controlled to enable the water outlet 111 of the water outlet nozzle 11 to discharge different water sprays. In this embodiment: a top surface of the water divider 3 is disposed with water dividing holes 32 corresponding to the first water dividing chamber 15 and the second water dividing chamber. The control mechanism 20 comprises a water dividing plate 33, and a bottom surface of the water dividing plate 33 is connected to the top surface of the water divider 3. The water dividing plate 33 is rotatably connected to the water divider 3 so that the water dividing plate 33 rotates to control whether the water outlet chamber 31 is in communication with the water divider holes 32 and to control a flow volume. The water dividing plate 33 comprises a water dividing shaft 331, and the water dividing shaft 331 hermetically and rotatably extends out of an upper side of the fixed base 4. The water dividing shaft 331 is configured to drive the water dividing plate 33 to rotate and is configured to control whether the water dividing holes 32 are in communication with the water outlet chamber 31 and to control a size of a communication area in communication with the water outlet chamber 31 (the larger the communication area, the greater the flow volume, and the smaller the communication area, the smaller the flow volume).
The driving mechanism 30 is operatively connected to the water dividing shaft 331 of the water dividing plate 33 and drives the water dividing plate 33 to achieve a stepless rotation adjustment. That is, an angle of a relative rotation of the water dividing plate 33 can be controlled steplessly, and the water dividing plate 33 can be controlled to any position within a preset rotation angle. The driving mechanism 30 comprises a push button 61, a slider 62, a push rod 63, and a swing rod 64. The push button 61, the slider 62, and the push rod 63 are each configured to slide relative to the installation portion 10. The push button 61 is fixedly connected to a first end of the slider 62 so that a user can operate the push button 61 to drive the slider 62 to slide. A second end of the slider 62 is connected to a first end of the push rod 63 by a positioning block 65 so that the slider 62 slides to drive the push rod 63 to slide. A first end of the swing rod 64 is fixedly connected to the water dividing shaft 331 of the water dividing plate 33 so that the swing rod 64 and the water dividing plate 33 rotate synchronously. The push rod 63 is fixedly connected with a connecting pin 631, and the swing rod 64 comprises a long slot 641. The connecting pin 631 is coupled in the long slot 641, and a sliding movement of the push rod 63 is configured to drive the connecting pin 631 to slide so as to drive the swing rod 64 to swing, to drive the water dividing shaft 331 to rotate, and to drive the water dividing plate 33 to rotate. In this embodiment, the slider 62 comprises a mounting groove 621, and the positioning block 65 is coupled in the mounting groove 621 so that the positioning block 65 is fixedly connected to the slider 62. The positioning block 65 comprises a mounting hole 651, and the push rod 63 is fixedly disposed with a fixed rod 633. The fixed rod 633 is coupled in the mounting hole 651, and the push rod 63 is slidably connected to the fixed base 4. A second end of the push rod 63 is disposed with a swing arm 632, and the connecting pin 631 is fixedly connected to the swing arm 632. Therefore, the entirety of the driving mechanism 30 is more compact. The swing arm 632 cooperates with the push rod 63 to define a cam-connecting rod mechanism. In this embodiment, the cam-connecting rod mechanism can also be other structures. An operation member (in this embodiment, the push button 61) is operatively connected to the cam-connecting rod mechanism, and the cam-connecting rod mechanism is operatively connected to the water dividing shaft 331 of the water dividing plate 33. The operation member is configured to move relative to the installation portion to drive the cam-connecting rod mechanism to move so as to drive the water dividing plate 33 to achieve a stepless angle adjustment. For a given rotation angle of the water dividing plate 33, the longer the swing arm 632 of the cam-connecting rod mechanism, the longer a required distance of the push button 61, and the smaller a force of the push button 61. For the given rotation angle of the water dividing plate 33, the shorter the swing arm 632 of the cam-connecting rod mechanism, the shorter the required distance of the push button 61 and the greater the force of the push button 61. Therefore any required working distant can be adjusted according to user needs. The driving mechanism 30 enables the user to adjust a rotation angle of the water dividing plate 33 steplessly, which can not only control whether water is flowing out but also control flow volumes of the first water inlet 112 and the second water inlet 113. Moreover, the driving mechanism 30 of this embodiment has a reasonable arrangement, a compact structure, and a stable and reliable operation connection.
The installation portion 10 further comprises a body 12, a decorative ring 13, and a decorative cover 14. The body 12 is disposed with a head 122 and a handle 123 fixedly connected together. The head 122 of the body 12 is fixedly connected to the decorative cover 14 in an upper-and-lower direction (i.e., a vertical direction), and the fixed base 4, the water divider 3, the cover plate body 2, and the cover 1 are fixedly connected between the head 122 of the body 12 and the decorative cover 14 in a downward direction. The decorative ring 13 is disposed between the cover 1 and the decorative cover 14. An inner side of the handle 123 is disposed with an axial shaft 121. The water inlet passage 5 comprises a portion disposed on the axial shaft 121 and the fixed base 4, and the water inlet passage 5 also comprises the water outlet chamber 31. The water source flows into the water outlet chamber 31 through the axial shaft 121 and the fixed base 4.
The push button 61 slides back and forth, the slider 62 is fixedly connected to the push button 61, and the slider 62 and the push button 61 move synchronously. The push button 61 moves back and forth and drives the water dividing plate 33 to rotate back and forth through the cam-connecting rod mechanism, and then a change of a mixing area (a flow volume) of the first water inlet 112 and the second water inlet 113 of the water outlet nozzle 11 is adjusted and controlled steplessly to enable a gradual change of a pattern of atomized water, lantern water, particle water, and shower water. Referring to
In this embodiment, the water outlet device has the following advantages. A variety of water sprays (i.e., water spray patterns) flow out of the same water outlet. In each of functional water spray states, each of the plurality of water outlets concurrently discharge water, a water spray is fuller, a cover area of the water spray is larger, and a water outflow is more uniform. When a multi-function shower is switched to the next gear position, residual water is not in a previous gear position as has occurred with previous solutions. Additionally, water spray particle size, impact force, and water spray shape can be steplessly adjusted to meet shower needs of different people.
