Description

Technical Field

[0001] The utility model belongs to the field of liquid diffusion, and in particular relates to a shower head. Background Art

[0002] When the liquid is sprayed on the shower head, the shower head diffuses the received liquid through multiple channels, so that the liquid is more evenly distributed after diffusion. Especially when the flow rate of the liquid changes, the shower head can diffuse different distances according to different channels.

[0003] However, when the existing shower head is sprayed with variable flow rate liquid, the diffusion stroke at the water distribution outlet is short, so that the diffusion distance of the liquid is also short, resulting in low uniformity of distribution of the liquid after diffusion, which greatly reduces the spraying effect of the variable flow rate liquid. Summary of the invention

[0004] The utility model aims to provide a shower head, which increases the diffusion stroke of its water distribution port and improves its diffusion distance and spraying effect as the liquid flow rate changes.

[0005] The technical solution is as follows:

[0006] A shower head comprises a rotating disc body, wherein the rotating disc body has an axis in the middle thereof, and a plurality of water distribution ports are arranged on the rotating disc body, and the plurality of water distribution ports are circumferentially distributed on the rotating disc body; along the axial direction of the rotating disc body, the water distribution ports are arranged obliquely, and the water distribution ports located on the lower surface of the rotating disc body are farther away from the axis than the water distribution ports on the upper surface; a diffusion port is also arranged on the rotating disc body, and the diffusion port is located on the outer edge of the rotating disc body, and the diffusion port is farther away from the axis than the water distribution port.

[0007] The shower head includes a rotating disc body, the middle part of which has an axis, the rotating disc body has an upper surface and a lower surface, the upper surface of the rotating disc body can rotate around the axis under the impact of water flow, the rotating disc body is penetrated by a water distribution port, and the rotating disc body is also provided with a diffusion port, the diffusion port is located at the outer edge of the rotating disc body, the diffusion port is far away from the axis relative to the water distribution port, the water flow impacting the upper surface of the rotating disc body is diffused to the bottom of the rotating disc body through the water distribution port and the diffusion port, along the axial direction of the rotating disc body, the water distribution port is inclined, the water distribution port located on the upper surface of the rotating disc body is close to the axis relative to the water distribution port on the lower surface, so that under the impact of variable flow water flow, the flow distance of the liquid is extended through the inclined water distribution port, so that the water flow at the water distribution port is diffused in the direction away from the axis, the diffusion surface of the water flow is increased, so that the distribution uniformity of the diffused water flow is higher, and the diffusion distance and spraying effect of the shower head on the water flow are improved.

[0008] In one embodiment, the rotating disk is provided with a first inclined surface at the diffuser, and a side of the first inclined surface close to the lower surface of the rotating disk is farther away from the axis than a side of the first inclined surface close to the upper surface of the rotating disk.

[0009] The first inclined surface is inclined along the upper surface of the rotating disk body and is inclined toward the lower surface of the rotating disk body. Under the impact of the variable flow liquid, the downward guiding distance of the liquid at the diffusion port is increased, so that the liquid at the diffusion port located at the outer edge of the rotating disk body is diffused farther downward, making the diffused liquid more evenly distributed, thereby improving the spraying effect of the shower head.

[0010] In one of the embodiments, relative to the radial direction of the rotating disk, the inclination angle of the water distribution port is greater than the inclination angle of the first inclined surface.

[0011] Since the water distribution port is close to the axis relative to the diffusion port, and relative to the radial direction of the rotating disk body, the inclination angle of the water distribution port is greater than the inclination angle of the first inclined surface. When a small flow of liquid impacts, the liquid sprayed by the water distribution port is closer to the axis, and as the liquid flow rate increases, the liquid sprayed by the inclined water distribution port gradually increases the diffusion distance away from the axis. Moreover, the inclination angle of the first inclined surface is lower than the inclination angle of the water distribution port, and the diffusion distance of the water flow at the diffusion port at the outer edge of the rotating disk body can be increased, so that the water flow sprayed by the shower head is more evenly distributed when the flow rate is variable, thereby improving the spraying effect.

[0012] In one embodiment, the water distribution port includes a first water distribution port and a second water distribution port, and the first water distribution port is closer to the axis relative to the second water distribution port; relative to the radial direction of the rotating disk, the inclination angle of the first water distribution port is greater than the inclination angle of the second water distribution port.

[0013] Since the second water distribution port is farther away from the axis than the first water distribution port, as the liquid flow rate increases, the second water distribution port can further connect with the liquid diffusion range of the first water distribution port to make the liquid diffusion more uniform. Relative to the radial direction of the rotating disk, the inclination angle of the second water distribution port is smaller than the inclination angle of the first water distribution port. The liquid in the second water distribution port has a farther diffusion distance than the liquid in the first water distribution port, thereby improving its spraying effect.

[0014] In one of the embodiments, along the axial direction of the rotating disk, the first water distribution port is configured as an arc-shaped transition on one side close to the axis.

[0015] Since the first water distribution port is closer to the axis than the second water distribution port, the first water distribution port is inclined, and along the axial direction of the rotating disk, the side of the first water distribution port close to the axis is set to be an arc-shaped transition. When the liquid flow rate is small, the flow distance of the first water distribution port is increased, the diffusion distance is improved, and a tangential force around the axis is generated when the liquid circulates, thereby increasing the rotation speed of the rotating disk, further making the distribution of the diffused liquid more even, and improving the spraying effect.

[0016] In one of the embodiments, the rotating disk is further provided with a protruding edge at the outer edge of the second water distribution outlet, and the second water distribution outlet close to the protruding edge is in a contracted shape.

[0017] Since the protruding edge is located at the outer edge of the second water distribution outlet, the second water distribution outlet close to the protruding edge is in a contraction shape, and the protruding edge is close to the flow outlet of the second water distribution outlet. When liquid is sprayed from the second water distribution outlet to the bottom of the rotating disk, the spraying pressure of the liquid at the contraction-shaped outlet increases, thereby having a longer diffusion distance.

[0018] In one embodiment, the rotating disk body includes a first rib, which is circumferentially distributed on one side of the rotating disk body along the axis to the outer edge of the rotating disk body; a second inclined surface is provided on the inner side of the first rib, and the second inclined surface is located above the second water distribution outlet along the axial direction from the lower surface to the upper surface of the rotating disk body, and the side of the second inclined surface close to the axis is higher than the side of the second inclined surface away from the axis.

[0019] The rotating disk body includes a first rib, which is circumferentially distributed on the rotating disk body. Along the axial direction from the lower surface to the upper surface of the rotating disk body, the first rib is located above the second water distribution port and is provided with a second inclined surface. When the liquid flow rate increases, the liquid is diffused from the second water distribution port to a farther end downward through the second inclined surface.

[0020] In one embodiment, the first rib includes a first guide wall and a second guide wall, the first guide wall is arranged on the rotating disk body, and the first guide wall has an arc-shaped transition; the first guide wall is provided with a protruding end, the protruding end is close to the second water distribution outlet, and along the axial direction of the rotating disk body, the height of the protruding end is higher than the height of the first guide wall along the axis to the second water distribution outlet; the second guide wall includes a first side and a second side, the second side is protrudingly arranged on the rotating disk body, the height of the second side matches the height of the protruding end, one end of the first side is connected to one side of the first guide wall, and the other end of the first side is connected to one side of the second side; the inner side of the first side forms the second inclined surface, the first side is located above the second water distribution outlet, the second water distribution outlet is formed between the first side, the second side, the first guide wall, and the rotating disk body, and the other side of the second side and the protruding end of the adjacent first guide wall form the diffusion outlet.

[0021] The first rib includes a first guide wall and a second guide wall. The first guide wall is arranged in an arc shape on the rotating disk body, and the rotating disk body rotates with the axis under the impact of water flow. The second guide wall and the first guide wall form the second water distribution port and the diffusion port, so that the liquid diffused at the second water distribution port diffuses obliquely downward from the middle of the rotating disk body, and the liquid at the diffusion port diffuses downward from the outer edge of the rotating disk body after approximately horizontal rotation and diversion, so that the liquid at the second water distribution port and the liquid at the diffusion port have different diffusion directions, thereby improving the uniformity of liquid diffusion and improving the spraying effect of the shower head.

[0022] In one of the embodiments, the rotating disc body is further provided with a second rib, the second rib protrudes from the other side of the rotating disc body, and the second rib surrounds the water distribution port.

[0023] A second rib is provided on the other side of the rotating disk body, and the second rib surrounds the water distribution port and further increases the flow distance of the water distribution port along the axial direction of the rotating disk body, thereby increasing the diffusion distance under the impact of variable flow liquid and improving the spraying effect.

[0024] In one embodiment, the second rib also surrounds the outer edge of the other side of the rotating disk.

[0025] The second rib also surrounds the outer edge of the other side of the rotating disk body, and further increases the flow distance of the liquid downward from the diffusion port along the axial direction of the rotating disk body, thereby increasing the diffusion distance under the impact of variable flow liquid and improving the spraying effect.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0034] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0035] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0037] like Figures 1 to 5The shower head shown in the figure comprises a rotating disc body 10, wherein the rotating disc body 10 has an axis 11 in the middle thereof, and the rotating disc body 10 has an upper surface and a lower surface. The upper surface of the rotating disc body 10 can rotate around the axis 11 under the impact of water flow, and the rotating disc body 10 is provided with a plurality of water distribution ports 12, and the plurality of water distribution ports 12 are circumferentially distributed on the rotating disc body 10; the rotating disc body 10 is also provided with a diffusion port 13, and the diffusion port 13 is located at the outer edge of the rotating disc body 10, and the diffusion port 13 is far away from the axis 11 relative to the water distribution port 12, and the water impacted on the rotating disc body 10 is transmitted through the water distribution port 12 and the diffusion port 13. The water flow on the upper surface of the rotating disk body 10 diffuses to the bottom of the rotating disk body 10. Along the axial direction of the rotating disk body 10, the water distribution port 12 is inclined. The water distribution port 12 located on the lower surface of the rotating disk body 10 is farther away from the axis 11 than the water distribution port 12 on the upper surface. Therefore, under the impact of the variable flow of water, the flow distance of the liquid is extended by the inclined water distribution port 12, so that the water flow at the water distribution port 12 is diffused in the direction away from the axis 11, increasing the diffusion surface of the water flow, so that the distribution uniformity of the diffused water flow is higher, thereby improving the diffusion distance and spraying effect of the shower head on the water flow.

[0038] like Figures 1 to 3 As shown, the diffuser 13 and the water distribution port 12 are further described as follows:

[0039] The rotating disk body 10 is provided with a first inclined surface 131 at the diffusion port 13. The side of the first inclined surface 131 close to the lower surface of the rotating disk body 10 is farther away from the axis 11 than the side of the first inclined surface 131 close to the upper surface of the rotating disk body 10. The first inclined surface 131 is inclined along the upper surface of the rotating disk body 10 toward the lower surface of the rotating disk body 10. Under the impact of the variable flow liquid, the downward guiding distance of the liquid at the diffusion port 13 is increased, so that the liquid at the diffusion port 13 located at the outer edge of the rotating disk body 10 is diffused farther downward, the diffused liquid is distributed more evenly, and the spraying effect of the shower head is improved. Since the water distribution port 12 is close to the axis 11 relative to the diffusion port 13, and relative to the radial direction of the rotating disk body 10, the inclination angle of the water distribution port 12 is greater than the inclination angle of the first inclined surface 131. When a small flow of liquid impacts, the liquid sprayed by the water distribution port 12 is closer to the axis 11, and as the liquid flow rate increases, the liquid sprayed by the inclined water distribution port 12 gradually increases the diffusion distance away from the axis 11. Moreover, the inclination angle of the first inclined surface 131 is lower than the inclination angle of the water distribution port 12, and the diffusion distance of the water flow at the diffusion port 13 on the outer edge of the rotating disk body 10 can also be increased, so that the water flow sprayed by the shower head is more evenly distributed when the flow rate is variable, thereby improving the spraying effect.

[0040] The water distribution port 12 includes a first water distribution port 121 and a second water distribution port 122. The first water distribution port 121 is closer to the axis 11 relative to the second water distribution port 122. As the liquid flow rate increases, the second water distribution port 122 can further connect the liquid diffusion range of the first water distribution port 121 to make the liquid diffusion more uniform; relative to the radial direction of the rotating disk body 10, the inclination angle of the first water distribution port 121 is greater than the inclination angle of the second water distribution port 122, and the liquid in the second water distribution port 122 has a farther diffusion distance than the liquid in the first water distribution port 121; due to the first The water distribution port 121 is closer to the axis 11 relative to the second water distribution port 122. The first water distribution port 121 is inclined. A third inclined surface 1211 is provided on the side of the first water distribution port 121 close to the axis 11. Along the axial direction of the rotating disk body 10, the third inclined surface 1211 is set as an arc-shaped transition. When the liquid flow rate is small, the flow distance of the first water distribution port 121 is increased, the diffusion distance is improved, and a tangential force around the axis 11 is generated when the liquid circulates, thereby increasing the rotation speed of the rotating disk body 10, further making the diffused liquid more evenly distributed and improving the spraying effect.

[0041] like Figures 1 to 5 As shown, the rotating disk 10 is further described as follows:

[0042] The rotating disk body 10 includes a first rib 15, which is circumferentially distributed on one side of the rotating disk body 10 along the axis 11 to the outer edge of the rotating disk body 10; the first rib 15 includes a first guide wall 151 and a second guide wall 152, the first guide wall 151 is arranged on the rotating disk body 10, and the first guide wall 151 is in an arc-shaped transition, so that the rotating disk body 10 rotates with the axis 11 under the impact of water flow; the first guide wall 151 is provided with a protruding end 1511, and the protruding end 1511 is close to the second water distribution port 122, along the rotating disk In the axial direction of the body 10, the height of the protruding end 1511 is higher than the height of the first guide wall 151 along the axis 11 to the second water distribution port 122; the second guide wall 152 includes a first side 1521 and a second side 1522, the second side 1522 is protrudingly arranged on the rotating disk body 10, the height of the second side 1522 matches the height of the protruding end 1511, one end of the first side 1521 is connected to one side of the first guide wall 151, and the other end of the first side 1521 is connected to one side of the second side 1522; the first side 1521 is provided with a second inclined surface on the inner side 15211, along the axial direction from the lower surface to the upper surface of the rotating disk body 10, the second inclined surface 15211 is located above the second water distribution port 122, and the side of the second inclined surface 15211 close to the axis 11 is higher than the side of the second inclined surface 15211 away from the axis 11. When the liquid flow rate increases, the liquid is diffused from the second water distribution port 122 to a further end downward through the second inclined surface 15211; the first side 1521 is located above the second water distribution port 122, and the first side 1521, the second side 1522, the first guide wall 151, and the The second water distribution port 122 is formed between the rotating disk bodies 10, and the other side of the second edge 1522 and the protruding end 1511 of the adjacent first guide wall 151 form the diffusion port 13, so that the liquid diffused at the second water distribution port 122 diffuses obliquely downward from the middle of the rotating disk body 10, and the liquid in the diffusion port 13 diffuses downward from the outer edge of the rotating disk body 10 after nearly horizontal rotation and diversion. While increasing the diffusion distance, the liquid in the second water distribution port 122 and the liquid in the diffusion port 13 have different diffusion directions, thereby improving the uniformity of liquid diffusion and thus improving the spraying effect of the shower head.

[0043] The rotating disk body 10 is also provided with a protruding edge 14 at the outer edge of the second water distribution port 122. The protruding edge 14 protrudes from one side of the first guide wall 151, and the protruding edge 14 is biased towards the second edge 1522. The second water distribution port 122 close to the protruding edge 14 is in a contraction shape, and the protruding edge 14 is close to the flow outlet of the second water distribution port 122. When liquid is sprayed from the second water distribution port 122 to the bottom of the rotating disk body 10, the spraying pressure of the liquid at the contraction outlet increases, thereby having a longer diffusion distance.

[0044] The rotating disk body 10 is also provided with a second rib 16, which protrudes from the other side of the rotating disk body 10, and the second rib 16 surrounds the water distribution port 12, along the axial direction of the rotating disk body 10, further increasing the flow distance of the water distribution port 12; the second rib 16 also surrounds the outer edge of the other side of the rotating disk body 10, along the axial direction of the rotating disk body 10, further increasing the downward flow distance of the liquid at the diffusion port 13, thereby increasing the diffusion distance under the impact of variable flow liquid and improving the spraying effect.

[0045] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
