DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Reference Figure 1-12 A water outlet device includes a water outlet assembly, which includes a water outlet housing 100. The water outlet housing 100 is provided with a first water outlet hole 111, a second water outlet hole 112 and a first water inlet hole 113. A first water outlet cavity 114, a second water outlet cavity 115 and a turbulent cavity 131 are formed in the water outlet housing 100. The first water outlet hole 111 is connected to the first water outlet cavity 114, the second water outlet hole 112 is connected to the second water outlet cavity 115, the first water inlet hole 113 is connected to the turbulent cavity 131, and the cavity wall of the turbulent cavity 131 is provided with a first water hole 121 connected to the first water outlet cavity 114 and a second water hole 121 connected to the second water outlet cavity 115. The first water hole 122 is located above the second water hole 122. The turbulence chamber 131 is provided with a guide channel 132, a vortex column 200, and a swinging member. One end of the swinging member is rotatably connected to the wall of the turbulence chamber 131. The vortex column 200 is located between the water outlet end of the guide channel 132 and the swinging member. The vortex column 200 is configured so that water flowing through the vortex column 200 can form a Karman vortex street downstream. The swinging member is configured to swing at the frequency of the Karman vortex street so that the other end of the swinging member alternately blocks the first water hole 121 and the second water hole 122. The water inlet end of the guide channel 132 is connected to the water inlet. Furthermore, the water outlet housing 100 is elongated, and the first water outlet chamber 114, the second water outlet chamber 115, and the turbulence chamber 131 are all elongated cavities. The first water outlet hole 111 and the second water outlet hole 112 are each provided with multiple water outlet holes 111 and 112 to create a wide shower spray effect. Furthermore, a flow stabilizing valve 1100 is provided on the first water inlet 113 .

[0035] Principle of Pulsed Water Generation: Within a certain Reynolds number range, the fluid will generate a Karman vortex street phenomenon. Specifically, the cross-sectional diameter d1 of the flow channel 132 and the flow rate Q can be configured according to the Reynolds number calculation formula Re = ρvd / μ (where ρ is the fluid density, v is the fluid velocity, d is the pipe diameter, and μ is the viscosity coefficient. The relationship between flow velocity v, flow rate Q, and pipe cross-sectional area A is: v = Q / A, A = πd² / 4). For example, when d1 = 8 mm and Q = 8 L / min, the Reynolds number Re is much greater than 4000, meeting the conditions for the generation of a Karman vortex street phenomenon.

[0036] In addition, in order to maintain a stable and continuous pulse frequency in the turbulent chamber 131, in addition to ensuring that the Reynolds number is sufficient, a sufficiently long flow field is also required, such as the distance between the vortex column 200 and the swing part. The size characteristics of the vortex column 200 (such as a cylinder, a triangular prism, etc.) and the swing part are also influencing factors. According to the vortex frequency calculation formula: f=St*v / d (where St is the Strouhal number (St≈0.21), v is the incoming flow velocity (m / s), and d is the characteristic size of the vortex generator (such as the cylinder diameter, unit m)), the vortex column size characteristics and vortex frequency can be deduced. For example, a cylindrical vortex column with a diameter of 6 mm has a vortex frequency of about 60 Hz. Then according to the natural frequency formula of the swing part: (where k is stiffness and m is mass; for a swing member with a rectangular cross section: k=(E* w*t^3) / (4 * L^3), where E is the elastic modulus, w is the width, t is the thickness, L is the length, and mass m = ρ*w*t *L, where ρ is density) and target frequency (such as 60Hz) to design the geometric parameters of the swing member (length L, width w ,thickness t ). This allows the vortex pulse and the oscillating member to oscillate at the same frequency, thereby alternately blocking the first water hole 121 and the second water hole 122, so that water flows intermittently into the first water outlet chamber 114 and the second water outlet chamber 115, thereby producing a pulsating water outlet effect.

[0037] In some embodiments of the present invention, the extension line of the axis of the diversion channel 132 intersects with the axis of the vortex column 200 and the rotation axis of the swinging member. The axis of the diversion channel 132 is in the left-right direction. The cross-sectional diameter of the diversion channel 132 is d1. The width of the vortex column 200 in the up-down direction is d2. The distance from the outlet end of the diversion channel 132 to the axis of the vortex column 200 is m1. The distance between the axis of the vortex column 200 and the rotation axis of the swinging member is m2. Let d1>d2, m1≥d1, 10*d2≥m2≥5*d2. In this embodiment, the vortex column 200 is a cylinder, and d2 is the diameter of the vortex column 200. d1>d2 ensures that the water flow fully impacts the vortex column 200, promoting the generation of a stable vortex street. When water flows out of the outlet of diversion channel 132, there may be initial disturbances or non-uniform velocity distribution. When m1 ≥ d1, sufficient distance for water flow development is provided to ensure stable flow and reduce irregularities in pulsating water flow. When m2 is within the range of 5*d2 to 10*d2, the vortex street has sufficient distance to develop and maintain its strength, ensuring efficient and synchronized oscillation of the oscillating member.

[0038] In some embodiments of the present invention, the total outlet area of the first and second outlet holes 111 and 112 is S1, the total outlet area of the first and second water holes 121 and 122 is S2, and the outlet area of the flow guide channel 132 is S3. S1 ≥ S2 ≥ 1.2*S3 is assumed. This relationship prevents the turbulent cavity 131 from interfering with the vortex waveform due to outlet resistance, ensuring stable Karman vortex generation.

[0039] In some embodiments of the present invention, the swing member includes a swing rod 300 and a plug 400. The swing rod 300 is in the shape of a flat rod. The plug 400 is provided with a limiting cavity 410 having an hourglass-shaped cross-section (the cross-section is perpendicular to the rotation axis of the swing member). The limiting cavity 410 gradually narrows from the left and right sides of the cavity to the middle, forming a narrow throat in the middle of the cavity. One end of the swing rod 300 is rotatably connected to the wall of the turbulence cavity 131, and the other end is inserted into the limiting cavity 410 and passes through the narrow throat. The swing rod 300 and the narrow throat are in a clearance fit. Furthermore, the swing rod 300 is provided with a rotating shaft column 310. The wall of the turbulence cavity 131 is provided with a positioning slot 133. The rotating shaft column 310 is rotatably inserted into the positioning slot 133, thereby achieving a rotational connection between the swing rod 300 and the wall of the turbulence cavity 131. The swing rod 300 swings back and forth under the action of the Karman vortex street, which can drive the plug 400 to move up and down. The plug 400 converts the swing of the swing rod 300 into linear motion of the plug 400 through the hourglass-shaped limiting cavity 410.

[0040] In some embodiments of the present invention, a limiting groove 134 is provided on the first wall of the turbulence chamber 131. The first water hole 121 and the second water hole 122 are located within the limiting groove 134. One end of the plug 400 extends into the limiting groove 134, and the other end is slidably connected to the second wall of the turbulence chamber 131 via a slide rail and slide groove structure, with the first wall and the second wall facing each other. The plug 400 can move up and down within the limiting groove 134. Furthermore, a vertical slide rail 135 is provided on the second wall, and a slide groove 420 is provided at one end of the plug 400. The limiting groove 134 and the slide rail and slide groove structure enable high-precision linear motion of the plug 400.

[0041] In some embodiments of the present invention, a flat and long waterfall outlet 117 is provided on the front side of the water outlet housing 100, and a long waterfall outlet cavity 116 is formed in the water outlet housing 100. The waterfall outlet 117 and the waterfall outlet cavity 116 are arranged in the left and right directions. The waterfall outlet 117 is connected to the waterfall outlet cavity 116. A second water inlet hole 118 is opened on either side wall of the waterfall outlet cavity 116. A grid piece 50 is provided in the waterfall outlet cavity 116. 0, a rectifier plate 600 and several rectifier columns 141. The grid plate 500 is located between the rectifier plate 600 and the waterfall outlet 117. The second water inlet 118 and the rectifier columns 141 are located behind the rectifier plate 600. The rectifier columns 141 are spaced apart. The grid plate 500 is provided with multiple vertical ribs 510, and the ribs 510 are spaced apart in the left-right direction. The rectifier plate 600 is provided with multiple injection holes 610, and the injection holes 610 are directly opposite the ribs 510. The rectifier columns 141 extend forward from the rear wall of the waterfall outlet chamber 116, and the axis of the rectifier columns 141 is perpendicular to the rectifier plate 600. Water flows from the second water inlet 118 into the waterfall outlet chamber 116. At this point, the water is quite turbulent and requires triple rectification through the rectifying column 141, the spray hole 610, and the ribs 510. This ensures that the water reaches the waterfall outlet 117 in a uniformly distributed laminar flow state, resulting in a balanced and transparent water flow. This ensures that the ejected waterfall water does not contract or branch over a long distance. The spray hole 610 must be directly opposite the ribs 510 to fully dissipate the impact of the water flow and achieve the desired rectification effect.

[0042] In some embodiments of the present invention, the water outlet housing 100 includes a front cover 110, a water diversion cover 120, a drainage cover 130 and a rear cover 140. The first water outlet 111, the second water outlet 112 and the waterfall outlet 117 are all provided on the front side of the front cover 110. A water diversion rib is provided on the inside of the front cover 110. The water diversion rib divides the internal space of the front cover 110 into a first partition, a second partition and a third partition. The water diversion cover 120 is sealed on the first partition and the second partition. The first partition and the water diversion cover 120 enclose a first water outlet cavity 111. 4. The second partition and the water diversion cover 120 enclose a second water outlet chamber 115. The first and second water diversion holes 121 and 122 are provided on the water diversion cover 120. The drainage cover 130 is sealed to the rear end face of the water diversion cover 120 to enclose a turbulent flow chamber 131. The rear cover 140 is located behind the drainage cover 130. The rectifying column 141 is fixed to the rear cover 140. The rear cover 140 is sealed to the front cover 110, enclosing a waterfall water outlet chamber 116 and a water inlet chamber. The water inlet chamber connects to the first water inlet hole 113 and the water inlet end of the diversion channel 132. The modular design of the water outlet housing 100 reduces mold complexity, reduces processing difficulty, and facilitates assembly.

[0043] In some embodiments of the present invention, a housing 700 and a connector 800 are further included. The connector 800 is fixedly connected to the housing 700. The connector 800 includes a joint portion 810 and a hollow water inlet portion 820. The joint portion 810 is connected to one end of the water inlet portion 820. The water inlet portion 820 is provided with a third water inlet hole 821. The joint portion 810 is hollow cylindrical. A first annular wall 811 is provided in the joint portion 810. The first annular wall 811 divides the internal space of the joint portion 810 into a coaxial annular cavity 812 and a central cavity 813. The central cavity 813 is provided with a water inlet hole 821. The water portion 820 is connected to the third water inlet hole 821, and the outer peripheral wall of the annular cavity 812 is provided with a fourth water inlet hole 814. The first water inlet hole 113 and the second water inlet hole 118 are both located at the right end of the water outlet shell 100. The right end of the water outlet shell 100 is rotatably sealed with the joint portion 810, and the left end of the water outlet shell 100 is rotatably connected to the outer shell 700. The second water inlet hole 118 is connected to the annular cavity 812, and the first water inlet hole 113 is connected to the central cavity 813, or the first water inlet hole 113 is connected to the annular cavity 812, and the second water inlet hole 118 is connected to the central cavity 813. Specifically, a second annular wall 150 is provided at the right end of the water outlet shell 100, and a third annular wall 160 is provided along the outer periphery of the first water inlet hole 113. The third annular wall 160 is located in the space surrounded by the second annular wall 150, and the second water inlet hole 118 is located between the second annular wall 150 and the third annular wall 160. The outer peripheral wall of the second annular wall 150 is sleeved with a first sealing ring, and the second annular wall 150 is embedded in the annular cavity 812. The first sealing ring is pressed against the inner peripheral wall of the annular cavity 812 and the outer peripheral wall of the second annular wall 150.

The second sealing ring is pressed against the inner peripheral wall of the central cavity 813 and the outer peripheral wall of the third annular wall 160. The connector 800 connects the outlet housing 100 to the inlet valve body 900. Once connected, the outlet housing 100 can rotate about its axis, enabling adjustable spray angles and providing greater flexibility and a wider range of applications. The rotation axis of the outlet housing 100 is coaxial with the axis of the annular cavity 812. Regardless of the angle to which the outlet housing 100 rotates, the second water inlet hole 118 and the first water inlet hole 113 remain connected to the annular cavity 812. Furthermore, a paddle 119 is fixed to the front of the outlet housing 100 for rotating the outlet housing 100 up and down. Furthermore, two limiting ribs 815 are provided on the outer wall of the joint portion 810 at intervals along the circumferential direction, and a positioning rib 180 is fixedly provided on the outer wall of the water outlet shell 100.
