Elaborate

In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments can be arbitrarily combined with each other.

As shown in Figures 1, 2, 3 and 4, embodiments of the present disclosure provide a water outlet device, such as a shower head, including: a body 1 and a cover 2.

Among them, the body 1 is provided with a water-containing cavity 11 with one end open. The wall of the water chamber 11 is provided with a water inlet hole 12 . The center line of the water inlet hole 12 deviates from the central axis of the water chamber 11, so that the water flow entering the water chamber 11 from the water inlet hole 12 rotates around the circumference of the water chamber 11, as shown in Figures 7 and 8. The central axis of the water-containing cavity 11 refers to a straight line perpendicular to the plane where the open end of the water-containing cavity 11 is located and passing through the center point of the open end of the water-containing cavity 11 .

The cover 2 covers the open end of the water chamber 11 and is fixedly connected to the body 1 . The cover 2 is provided with a plurality of water outlets 24 communicating with the water chamber 11 .

The water outlet device provided by the embodiment of the present disclosure improves the water inlet hole 12 on the wall of the water chamber 11. In a conventional water outlet device, the center line of the water inlet hole 12 is perpendicularly intersecting or collinear with the central axis of the water chamber 11. Therefore, the water flow entering the water chamber 11 from the water inlet hole 12 will flow directly to the center of the water chamber 11. , then spreads around, and is discharged downward through the water outlet 24. In the embodiment of the present disclosure, the water inlet hole 12 (relative to the existing water inlet hole) is arranged at an angle, so that the water flow entering the water chamber 11 from the water inlet hole 12 has a partial velocity along the tangential direction of the water chamber 11. Therefore, The water flow entering the water chamber 11 through the water inlet hole 12 will rotate around the circumference of the water chamber 11 .

In other words, the water flow entering the water chamber 11 from the water inlet hole 12 will rotate in the water chamber 11, and the direction of the water flow rotation is the transverse direction, in the horizontal plane; and the water outlet direction of the surface cover 2 is the longitudinal direction, in the horizontal plane. vertically in plane. Therefore, the water flow will form a 90° cut with the water outlet hole 24. When flowing through the water outlet hole 24, only part of the water in the lower layer will be sprayed out through the water outlet hole 24, and the water flow will generate waves during the rotation process, thereby causing the cover 2 to spray out. The water flow produces a pulsating effect, that is: pulse water spray. What is sprayed is not a water flow with constant pressure, but a water flow with a pulsating impact effect. The impact effect of the pulse water flow is sometimes large and sometimes small, which can play a massage function, thereby making The water outlet device has a massage function, which enriches the functions of the water outlet device, improves the user experience, and is conducive to increasing the market competitiveness of the product.

Alternatively, the center line of the water inlet hole 12 can also be parallel to the center line of the existing water inlet hole, which is equivalent to the entire water inlet hole 12 being moved, or the center line of the water inlet hole 12 can be deviated from the center of the water chamber 11 axis, thereby causing the water flow to rotate in the water chamber 11.

In an exemplary embodiment, the body 1 also includes a handle 13, which is connected to the side wall of the water chamber 11. The handle 13 is provided with a water inlet channel 14, and the water inlet hole 12 is provided in the water chamber 11. side wall, and is connected with the water inlet channel 14, as shown in Figures 6, 7 and 8. In other words, the shower head is a hand-held shower head, so that the center line of the water inlet hole 12 can be perpendicular to and not intersecting with the central axis of the water chamber 11, which is conducive to further improving the swirling effect of the water flow and further improving the pulse massage of the shower head. Effect.

Of course, the shower head can also be an overhead shower head.

In an exemplary embodiment, as shown in Figures 1, 9 and 10, the water outlet device may also include: an impeller 3, which is rotatably provided in the water chamber 11 and is configured to pass through the water inlet hole 12. It rotates around the central axis of the water chamber 11 under the impact of the water flow entering the water chamber 11 .

The setting of the impeller 3 can increase the swirling effect of the water flow in the water chamber 11 and produce a vortex supercharging effect, which makes the pulsating impact effect of the water coming out of the water outlet device better, which is conducive to further improving the user experience and further increasing the product's durability. Market Competitiveness.

Of course, the water outlet device may not include the impeller 3 . Since the water inlet hole 12 is an inclined hole, swirling water flow can still be generated in the water chamber 11, thereby achieving a pulse massage effect.

In an exemplary embodiment, as shown in Figures 9 and 10, the impeller 3 includes: a rotating shaft 31 and a blade assembly.

Among them, the rotating shaft 31 is rotatably connected to the body 1 .

The blade assembly is connected to the rotating shaft 31 . The blade assembly has a driving part 34 and a boosting part 35 . The driving part 34 is provided corresponding to the water inlet hole 12, and is configured to rotate under the impact of the water flow ejected from the water inlet hole 12 to drive the impeller 3 to rotate. The pressurizing part 35 is provided corresponding to the water outlet hole 24 and is configured to increase the water outlet pressure of the water outlet hole 24 .

The driving part 34 is arranged corresponding to the water inlet hole 12 , which means that the driving part 34 can rotate to a position facing the water inlet hole 12 during the rotation process. The supercharging part 35 is arranged corresponding to the water outlet hole 24 , which means that the supercharging part 35 can rotate to a position facing the water outlet hole 24 during the rotation process.

The impeller 3 includes a rotating shaft 31 and a blade assembly. The rotating shaft 31 is rotatably connected to the body 1, which can ensure the stability and reliability of the impeller 3. The driving part 34 of the blade assembly is facing the water inlet hole 12 , so the water flow entering the water chamber 11 from the water inlet hole 12 will directly impact the driving part 34 , causing the driving part 34 to rotate, thereby realizing the rotation of the entire impeller 3 . The pressurizing part 35 is facing the water outlet hole 24 of the face cover 2, and can pressurize the water toward the water outlet hole 24 during the rotation process, thus exerting a pressurizing effect, which is beneficial to improving the pulse massage effect of the water discharged by the water outlet device.

In an exemplary embodiment, the plurality of water outlets 24 are divided into an inner ring hole group 241 and an outer ring hole group 242. As shown in Figures 2, 4, and 11, the inner ring hole group 241 is located in the outer ring hole. Radially inner side of group 242.

As shown in FIGS. 5 , 7 , 12 and 13 , the blade assembly includes: a first blade 32 and a second blade 33 . The first blade 32 is arranged corresponding to the inner ring hole group 241, that is, the first blade 32 can rotate to a position facing the inner ring hole group 241 during the rotation process. The first blade 32 includes a pressurizing portion 35 . The second blade 33 is located outside the first blade 32 and is arranged corresponding to the outer ring hole group 242 . The second blade 33 includes a driving part 34 and a supercharging part 35 .

The plurality of water outlets 24 are divided into an inner ring hole group 241 and an outer ring hole group 242, which facilitates the user to select the water outlet area of the water outlet device according to needs, such as allowing only the inner ring hole group 241 to discharge water, or only allowing the outer ring hole group 242 to discharge water. , or both the inner ring hole group 241 and the outer ring hole group 242 discharge water, which is also beneficial to enriching the functions of the water outlet device. The inner hole group 241 may include a plurality of water outlets 24 arranged in an annular array. The outer hole group 242 may include a plurality of water outlets 24 arranged in an annular array.

Accordingly, the blade assembly includes a first blade 32 and a second blade 33 . The first blade 32 is arranged corresponding to the inner ring hole group 241 and is an inner ring blade. The second blade 33 is arranged corresponding to the outer ring hole group 242 and is an outer ring blade. The driving part 34 is provided on the second blade 33 relatively outward. Under the impact of the water flow ejected from the water inlet hole 12, a greater torque is generated, which is beneficial to promoting the rotation of the impeller 3. The first blade 32 and the second blade 33 both have a pressurizing part 35, so both can have a pressurizing effect, which is beneficial to improving the pulsating massage effect of the water outlet device.

In one example, the number of first blades 32 located in the inner ring is multiple, and the plurality of first blades 32 are arranged at intervals along the circumferential direction of the impeller 3 . There are multiple second blades 33 located in the outer ring, and the plurality of second blades 33 are arranged at intervals along the circumferential direction of the impeller 3 .

Therefore, the space between adjacent first blades 32 forms a water passage, and the space between adjacent second blades 33 also forms a water passage. When the water rotates along the circumferential direction of the water chamber 11 driven by the impeller 3, some water will also flow downward through the water passage to ensure that the water outlet can discharge water.

In an exemplary embodiment, as shown in FIGS. 5 , 7 , 9 , 10 , 12 and 13 , the pressurizing part 35 includes: a horizontal section 351 and an inclined section 352 .

The horizontal section 351 is perpendicular to the central axis of the water chamber 11 . The inclined section 352 is connected to the horizontal section 351 and is inclined relative to the horizontal section 351 .

The supercharging part 35 includes a horizontal section 351 and an inclined section 352. The horizontal section 351 can block the water outlet holes 24 below it, thereby increasing the water outlet pressure of other unblocked water outlets 24, making the water outlet more impactful. That is, during the rotation process, the impeller 3 can intermittently block water from the water outlet hole 24, thereby blocking water and boosting pressure. During the rotation process, the inclined section 352 can produce downward thrust on the water to achieve a secondary pressurization effect. Therefore, during the rotation process of the impeller 3, it can produce the effects of vortex pressurization and water blocking pressurization, so that the pulsating water flow sprayed by the water outlet device can produce a better massage effect.

In an exemplary embodiment, as shown in FIGS. 5 , 7 , 9 , 10 , 12 and 13 , the impeller 3 may further include: a first water retaining ring 36 and a second water retaining ring 37 .

The first water retaining ring 36 is connected to the radially outer end of the first blade 32 and the radially inner end of the second blade 33 . The second water retaining ring 37 is connected to the radial outer end of the second blade 33 .

The arrangement of two water retaining rings can make the downward pressure generated by the inclined section 352 more concentrated, which is helpful to prevent the water under the inclined section 352 from shunting to both radial directions under the action of pressure, so the downward pressurization effect is better.

In an exemplary embodiment, as shown in Figures 5, 7, 9, 10, 12 and 13, the first water retaining ring 36 is parallel to the central axis of the water chamber 11, and the second water retaining ring 36 is parallel to the central axis of the water chamber 11. The water retaining ring 37 is parallel to the central axis of the water chamber 11 . In other words, both the first water retaining ring 36 and the second water retaining ring 37 are straight cylindrical structures, and the side wall surfaces of the straight cylindrical structures are parallel to the central axis of the water chamber 11 .

This can make the downforce generated by the inclined section 352 more concentrated, so that the water under the inclined section 352 cannot flow to both radial sides and can only flow downward, so the pressurization effect is better.

In an exemplary embodiment, as shown in FIGS. 5 , 7 , 9 , 10 , 12 and 13 , the horizontal section 351 of the first blade 32 and the lower end of the inclined section 352 of the first blade 32 connected. The horizontal section 351 of the second blade 33 is connected to the lower end of the driving part 34 , and the horizontal section 351 of the second blade 33 is connected to the upper end of the inclined section 352 of the second blade 33 . The horizontal section 351 of the first blade 32 is located on the lower side of the horizontal section 351 of the second blade 33 , that is, the plane where the horizontal section 351 of the first blade 32 is located is different from the plane where the horizontal section 351 of the second blade 33 is located, and the first The plane where the horizontal section 351 of the blade 32 is located is closer to the plane where the outlet holes 24 are located than the plane where the horizontal section 351 of the second blade 33 is located, and is configured to block a part of the outlet holes 24 of the inner ring hole group 241 .

Therefore, the inclined section 352 of the first blade 32 is positioned upward, and the horizontal section 351 is positioned downward. In this way, the distance between the horizontal section 351 of the first blade 32 and the inner ring hole group 241 is relatively close, which can play a better intermittent water blocking effect on the inner ring hole group 241 and help increase the water outlet pressure.

For the second blade 33, the driving part 34 is positioned upward, the horizontal section 351 is positioned in the middle, and the inclined section 352 is positioned downward. The driving part 34 is positioned upward, which facilitates increasing the rotation position of the water flow in the water chamber 11, thereby improving the pulse effect of water discharge. The upper position refers to the direction away from the water outlet hole 24 , and the lower position refers to the direction closer to the water outlet hole 24 . The horizontal section 351 is located in the middle, which can prevent the horizontal section 351 from contacting the cover 2, which is beneficial to reducing the rotational friction of the impeller 3. The inclined section 352 is located lower and can have a better pressurizing effect on the outer ring hole group 242.

Of course, the first blade 32 and the second blade 33 can also adopt the same design.

In an exemplary embodiment, as shown in FIGS. 5 , 9 and 10 , the axial height of the first water retaining ring 36 is greater than the axial height of the second water retaining ring 37 . The axial height of the pressure increasing portion 35 of the first blade 32 is greater than the axial height of the pressure increasing portion 35 of the second blade 33 . In this way, the first blade 32 can play a better intermittent water blocking effect on the inner ring hole group 241, which is beneficial to increasing the water outlet pressure.

In one example, as shown in FIGS. 5 , 9 , and 10 , the lower end of the first water retaining ring 36 is flush with the lower end of the first blade 32 , so that the first water retaining ring 36 can effectively prevent the first blade 32 from being damaged. The water flow pressed down by the inclined section 352 flows radially outward, thereby achieving a better pressurizing effect. The upper end of the first water retaining ring 36 is higher than the upper end of the first blade 32, which is beneficial to increase the contact area between the first water retaining ring 36 and the driving part of the first blade 32, thereby improving the connection strength.

The upper end of the second water blocking ring 37 is flush with the upper end of the supercharging portion 35 of the second blade 33 , and the lower end of the second water blocking ring 37 is flush with the lower end of the supercharging portion 35 of the second blade 33 . In this way, the second water retaining ring 37 can effectively prevent the water flow pressed down by the inclined section 352 of the second blade 33 from flowing radially outward, thereby achieving a better pressurizing effect.

In an exemplary embodiment, as shown in Figures 1, 5, 9, and 10, a cylindrical buckle 111 is provided in the middle of the top wall of the water chamber 11, and the rotating shaft 31 is a hollow shaft. The hollow shaft is sleeved on the cylindrical buckle 111, is engaged with the cylindrical buckle 111, and can rotate around the cylindrical buckle 111.

In this way, during assembly, the impeller 3 can be directly clamped on the cylindrical buckle 111 of the body 1, and the assembly is more convenient.

The cylindrical buckle 111 may include a plurality of buckles arranged opposite to each other, such as two buckles arranged opposite to each other.

In an exemplary embodiment, as shown in FIGS. 4 and 11 , the plurality of water outlets 24 form at least one water outlet ring. The water outlet ring includes a plurality of water outlets arranged in an annular array along the circumferential direction of the cover 2 . twenty four.

The center line of the water outlet hole 24 of the water outlet ring is inclined relative to the central axis of the water chamber 11, as shown in Figures 12, 13 and 20, and the center line of the water outlet hole 24 of the water outlet ring is in the transverse direction of the water chamber 11. The projection on the cross section is tilted relative to the radial direction of the water chamber 11 (as shown in Figure 17), so that the water flow ejected from the water outlet ring forms an annular water flow with thick ends and a thin middle, as shown in Figures 18 and 19.

In this example, the center line of the water outlet hole 24 refers to a straight line passing through the midpoint of the lower end section of the hole and the midpoint of the upper end section of the hole. The projection of the center line of the water outlet hole 24 of the water outlet ring on the cross section of the water containing cavity 11 is tilted relative to the radial direction of the water containing cavity 11, which means that the center line of each water outlet hole 24 of the water outlet ring is in the water containing cavity. The projections on the cross section of 11 are all straight lines that do not pass through the center of the cross section, as shown in Figure 17.

In this way, the water flow ejected from the water outlet ring can form a "small waist" shape, as shown in Figures 18 and 19, which brings a beautiful visual experience to the user and is also conducive to improving the market competitiveness of the product.

In one example, the outer ring hole group 242 includes at least one water outlet ring, and the center line of the water outlet holes 24 of the inner ring hole group 241 is parallel to the central axis of the water chamber 11 (that is, arranged in the vertical direction). In this way, the water sprayed from the outer ring hole group 242 has a "small waist" shape and will not be interfered by the inner ring hole group 241, which can provide the user with a wonderful visual experience.

Among them, the angle between the center line of the water outlet hole 24 and the central axis of the water chamber 11 is marked as b (as shown in Figures 18 and 19). The center line of the water outlet hole 24 is on the cross section of the water chamber 11. The projection is between the radial direction of the water chamber 11 (that is, the direction of the line connecting the center of the water outlet port of the water outlet hole 24 and the center of the water chamber 11 in the projection on the same cross-section of the water chamber 11). The supplementary angle of the angle between is denoted as a (as shown in Figure 11). By adjusting the size of a and b, the waistline position and size of the "small waist" can be adjusted to achieve the dual experience of appearance and impact massage.

In Figures 11 and 17, the outer ring hole group 242 includes two water outlet rings. The C-C section line is the projection of the center line of the outlet hole 24 of the outer outlet ring located in the 12 o'clock direction on the horizontal plane (parallel to the cross-section of the water chamber 11). The center of the outlet port of the outlet hole 24 is The connecting line between the centers of the water-containing chambers 11 (i.e., the dotted line in the figure) is the radial direction of the water-containing cavity 11, and the horizontal line on the upper side in the figure is perpendicular to the dotted line. Therefore, the angle between the horizontal line on the upper side and the section line in the C-C direction is the projection of the centerline of the outlet hole 24 of the outer outlet ring on the cross section of the water chamber 11 and the radial direction of the water chamber 11 The angle a between.

The cross-section line in the D-D direction is the projection on the horizontal plane of the center line of the outlet hole 24 of the inner outlet ring located in the 12 o'clock direction, and the connection line between the center of the outlet port of the outlet hole 24 and the center of the water chamber 11 (i.e., the dotted line in the figure) is the radial direction of the water chamber 11, and the horizontal line located on the lower side in the figure is perpendicular to the dotted line. Therefore, the angle between the horizontal line on the lower side and the section line in the D-D direction is the projection of the centerline of the outlet hole 24 of the inner outlet ring on the cross section of the water chamber 11 and the radial direction of the water chamber 11 The angle a between.

In an exemplary embodiment, the depth of the water outlet hole 24 ranges from 1.5 mm to 3.5 mm.

The depth of conventional water outlet holes 24 is generally in the range of 0.35mm to 0.5mm. In this embodiment, the depth of the water outlet holes 24 is increased to a range of 1.5mm to 3.5mm, such as 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, etc., which is equivalent to each water outlet hole 24 forming a small water outlet. The cavity can play a better throttling and pressurizing effect, which is conducive to further improving the pulse massage effect of the water outlet device.

In an exemplary embodiment, along the water outlet direction, the cross-sectional area of the water outlet hole 24 gradually decreases, as shown in Figures 12, 13 and 20.

Along the water outlet direction, the cross-sectional area of the water outlet hole 24 gradually decreases, forming an inverted conical structure, which is conducive to further increasing the water outlet pressure, thereby being conducive to further improving the pulse massage effect of the water outlet device.

In an exemplary embodiment, as shown in FIGS. 1 and 5 , the face cover 2 includes: a face cover main body 21 , a soft rubber water outlet sleeve 22 and a bracket 23 .

The cover body 21 is provided with a plurality of through holes 211 . The soft rubber water outlet sleeve 22 is provided with water outlet protrusions 221 corresponding to the plurality of through holes 211. The water outlet protrusion 221 is passed through the through hole 211, and the water outlet protrusion 221 is provided with a water outlet hole 24. The bracket 23 is provided with water holes 231 corresponding to the plurality of water outlets 24 one-to-one. The bracket 23 is fixedly connected to the soft rubber water outlet sleeve 22, and the soft rubber water outlet sleeve 22 is pressed onto the cover body 21.

When assembling, align the water hole 231 of the bracket 23 with the upper entrance of the water outlet protrusion 221 of the soft rubber water outlet sleeve 22, align the water outlet protrusion 221 of the soft rubber water outlet sleeve 22 with the through hole 211 of the cover body 21 and insert it. , and fix the bracket 23 and the soft rubber outlet sleeve 22 together, and finally assemble the assembled module and the body 1 together.

Among them, the bracket 23 and the soft rubber water outlet sleeve 22 can be fixedly connected using a welding process.

Of course, as shown in Figures 14, 15 and 16, the soft water outlet sleeve 22 and the bracket 23 can also be omitted. In other words, the cover 2 can be a single component instead of a module formed by a combination of three components.

In an exemplary embodiment, the plurality of through holes 211 form at least one ring group, and the ring group includes a plurality of through holes 211 arranged in an annular array along the circumferential direction of the cover 2 . The center line of the through hole 211 of the ring group is inclined relative to the central axis of the water chamber 11, as shown in Figure 20, and the projection of the center line of the through hole 211 of the ring group on the cross section of the water chamber 11 is relative to The radial direction of the water chamber 11 is inclined.
