In addition, the technical features mentioned in the different embodiments of the application described below can be combined with one another as long as they do not conflict with one another.

In the prior art, in order to realize the swing of the spray sprayed by the spray nozzle, a motor is added to drive the water outlet structure to swing so as to realize the swing of the spray. But need set up dynamic seal between the motor shower nozzle casing, perhaps go out between water structure and the casing, dynamic seal not only increases the frictional force when the motor operates, still leads to sealed inefficacy easily under long-time operation, and then increases the risk of leaking of shower nozzle, reduces the reliability of shower nozzle.

Because of the addition of the motor and some moving parts, the structure of the spray head is complex, the volume and the cost of the spray head are increased, and meanwhile, the spray head is difficult to assemble; and because the structure is complicated, any part damages, can all lead to the unable normal use of whole shower nozzle, consequently can reduce the reliability of shower nozzle.

In order to solve the above technical problems, an embodiment of the present application provides a spray head 100, as shown in fig. 1 and 2, the spray head 100 includes a housing 1 and a rotating member 3, the housing 1 is provided with a accommodating cavity 11, and the rotating member 3 is rotatably disposed in the accommodating cavity 11.

For the above-mentioned housing 1, as shown in fig. 2 and 3, the housing 1 is further provided with a first water inlet hole 12 and a first water outlet hole 13, where the first water inlet hole 12 and the first water outlet hole 13 are both communicated with the accommodating cavity 11, the first water inlet hole 12 is used for feeding liquid, and the first water outlet hole 13 is used for discharging liquid, and in the embodiment of the present application, the liquid is described by taking water as an embodiment, so that the first water outlet hole is used for spraying water to form water spray. When the water in the accommodating cavity 11 is directly discharged from the first water outlet hole 13, the water spray is ejected from the first water outlet hole 13 along the extending direction of the first axis.

As shown in fig. 2 and 3, the rotating member 3 is rotatably disposed in the accommodating chamber 11 about the first axis, and the rotating member 3 is configured to rotate under the force of the liquid ejected from the first water inlet 12. That is, the water flowing into the accommodating chamber 11 from the first water inlet 12 impacts the rotating member 3 and drives the rotating member 3 to rotate, and the specific implementation thereof will be described below.

As shown in fig. 2 and 4, the first side 31 of the rotating member 3 facing the first water outlet hole 13 is provided with a water outlet groove 32, an acute angle is formed between the extending direction of the water outlet groove 32 and the first axis, one end of the water outlet groove 32 is communicated with the accommodating cavity 11, and the other end of the water outlet groove 32 is communicated with the first water outlet hole 13. The water flow in the accommodating cavity 11 flows into the water outlet groove 32 from the end, which is communicated with the accommodating cavity 11, of the water outlet groove 32, flows into the first water outlet hole 13 from the end, which is communicated with the first water outlet hole 13, of the water outlet groove 32, and finally is sprayed out from the first water outlet hole 13. Since the extending direction of the water outlet groove 32 forms an acute angle with the first axis, the flow direction of the water flow in the water outlet groove 32 forms an acute angle with the first axis, so that when the water flow is ejected from the first water outlet hole 13 to form a spray, an acute angle is formed between the spray and the first axis. Then, the rotating member 3 rotates under the action of the water flow sprayed from the first water inlet 12, so that the water outlet 32 rotates around the first axis, and the spray sprayed from the first water outlet 13 also rotates around the first axis, so as to swing the spray.

Compared with the prior art, the application realizes the swing of the spray through the cooperation of the rotating piece and the first water outlet hole 13 of the first water inlet hole 12, does not need to arrange complex moving parts or motors, simplifies the structure, improves the reliability, reduces the cost and reduces the installation difficulty. And the rotating member 3 is arranged in the accommodating cavity 11, so that an additional sealing structure is not required to be arranged, the water leakage risk of the spray head 100 is reduced, and the reliability of the spray head 100 is further improved.

Optionally, the angle presented between the direction of extension of the water outlet channel 32 and the first axis is less than 30 degrees. Alternatively, the cross section of the water outlet channel 32 is rectangular.

In some embodiments, as shown in fig. 4 and 5, the rotating member 3 includes an impeller portion 33 and a control portion 34 arranged along a first axis, and the impeller portion 33 is rotatably disposed in the accommodating chamber 11 about the first axis; the control portion 34 is located on a side of the impeller portion 33 facing the first water outlet hole 13, and extends along the first axis, and the water outlet groove 32 is opened in the control portion 34. The impeller portion 33 is driven to rotate by water flow, and the control portion 34 rotates synchronously with the impeller portion 33 and cooperates with the first water outlet 13 to form a swinging spray. By providing the water outlet tank 32 in the control unit 34 so that the water outlet tank 32 is spaced from the impeller unit 33, the problem that the water flow flowing out of the first water inlet 12 directly impacts into the water outlet tank 32, which causes an increase in the water pressure in the water outlet tank 32 and further causes an abrupt increase in the water flow pressure ejected from the first water outlet 13, is solved, and the problem that the water flow pressure ejected from the first water outlet 13 is constantly changed is improved, thereby improving the use experience.

Optionally, the control part 34 has a cylindrical shape, one end is connected to the impeller part 33, and the other end abuts against the inner wall of the accommodating cavity 11 and covers the first water outlet hole 13.

As shown in fig. 4 and 5, the impeller 33 includes a rotary shaft 331 and blades 332 provided on the outer peripheral surface of the rotary shaft 331, and the central axis of the first water outlet 13 interferes with the blades 332 to rotate the impeller 33 under the force of the liquid discharged from the first water inlet 12. The rotating shaft 331 is rotatably disposed in the accommodating cavity 11, and the blades 332 are disposed on the outer peripheral surface of the rotating shaft 331, and since the central axis of the first water outlet 13 interferes with the blades 332, the water flow ejected from the first water outlet 13 will strike the blades 332, so as to push the impeller 33 to rotate. Wherein, the angle between the normal of the vane 332 and the central axis of the first water outlet hole 13 is smaller than 90 degrees.

Alternatively, the impeller portion 33 may be an axial flow impeller or a mixed flow impeller.

Alternatively, the water inlet direction of the first water outlet hole 13 may be perpendicular to the first axis or may be parallel to the first axis.

In some embodiments, as shown in fig. 2, 3 and 5, a stop portion 14 and a shaft body 15 are disposed in the accommodating cavity 11 along the first axis at intervals, one end of the impeller portion 33 is provided with a mounting groove 333, the shaft body 15 is partially disposed in the mounting groove 333, and the other end of the impeller portion 33 abuts against the stop portion 14, so that the impeller portion 33 is rotatably disposed in the accommodating cavity 11 around the first axis. The impeller portion 33 is located between the stopper portion 14 and the shaft body 15, and the shaft body 15 is inserted into the mounting groove 333, so that the impeller portion 33 is rotatably mounted in the accommodating chamber 11. The stop portion 14 may be disposed at the center of the accommodating cavity 11, and the shaft body 15 may be disposed on an inner wall of the accommodating cavity 11.

In some embodiments, the stop portion 14 is annular, two sides perpendicular to the axial direction are connected to the inner wall of the accommodating cavity 11, and a hole in the middle of the stop portion 14 is used for the control portion 34 to pass through.

In some embodiments, as shown in fig. 2 and 3, an overflow channel 141 is provided between the stop portion 14 and the inner wall of the accommodating cavity 11, for the water to pass through, so that the water flows from the side of the stop portion 14 facing the impeller portion 33 to the side of the stop portion 14 facing the first water outlet hole 13. It can be appreciated that the stop portion 14 divides the accommodating chamber 11 into two parts, one part is communicated with the first water outlet hole 13, the other part is communicated with the first water inlet hole 12, and the two parts of accommodating chambers 11 are communicated through the overflow channel 141.

In some embodiments, as shown in fig. 4 and 5, both sides of the impeller portion 33 along the first axis direction are provided with convex rings 334, the convex rings 334 are used for contacting with the stop portion 14 or the inner wall of the accommodating cavity 11 to reduce friction force, and when the accommodating cavity 11 is filled with water, a water film can be formed between the convex rings 334 and the stop portion 14 or the inner wall of the accommodating cavity 11 to further reduce friction force.

Alternatively, the stopper 14 is provided integrally with the housing 1, and the shaft body 15 is provided integrally with the housing 1.

In some embodiments, as shown in fig. 2 and 3, the inner wall of the housing 1 is provided with a groove 16 extending along the first axis, the first water outlet 13 is provided at the bottom of the groove 16, the control part 34 is at least partially located in the groove 16, and the water outlet groove 32 extends out of the groove 16. By inserting the control part 34 into the groove 16, a certain limit function can be achieved on the whole rotating member, so that the rotating member can stably rotate; and the inner wall of the groove 16 and the water outlet groove 32 form a drainage channel, so that most of water in the water outlet groove 32 enters the water outlet groove 32 from a part extending from the water outlet groove 32 to the outside of the groove 16, but not enters the water outlet groove 32 from a position close to the first water outlet hole 13, and therefore the water entering the water outlet groove 32 can be accelerated along the water outlet groove 32 until being sprayed out from the first water outlet hole 13, and the swing amplitude of water spray sprayed out by the spray head 100 can be enhanced. Further, the control portion 34 and the groove 16 are both cylindrical, and a movement gap is provided between the control portion 34 and the inner wall of the groove 16, so that the control portion 34 can rotate within the groove 16 relative to the groove 16.

It will be appreciated that the low-velocity water flowing into the first water outlet hole 13 through the movement gap will be attached to the high-velocity water flowing into the first water outlet hole 13 through the water outlet groove 32 and be ejected from the first water outlet hole 13 together. If the proportion of the low-speed water is large, the impact force of the water spray ejected from the first water outlet 13 is reduced. To improve this problem, the movement gap may be set smaller so that less water flows into the first side 31 through the movement gap. For example, the movement gap may be set to less than one tenth of the depth of the water outlet channel 32.

In some embodiments, as shown in fig. 4 and 5, the control portion 34 includes a head portion 341 at least partially located in the groove 16, the outer diameter of both ends of the head portion 341 is smaller than the outer diameter of the middle portion, and the movement gap is formed between the middle portion of the head portion 341 and the inner wall of the groove 16, so that the head portion 341 can rotate in the groove 16 relative to the groove 16; the water outlet groove 32 penetrates from one end of the head 341 to the other end of the head 341 so that the water outlet groove 32 extends out of the groove 16, and thus water in the accommodating chamber 11 can enter the water outlet groove 32.

In some embodiments, as shown in fig. 6, the first water inlet 12 has a gradually decreasing inner diameter along the water inlet direction. When the water flow passes through the first water inlet 12, the inner diameter is gradually reduced, so that the speed of the water flow is gradually increased, the impact force of the water flow on the rotating member 3 is increased, the rotating speed of the rotating member 3 is increased, and the problem that the rotating member 3 is difficult to rotate due to the fact that the impact force is too small is solved.

Alternatively, the cross section of the first water inlet 12 is elliptical.

In some embodiments, the cross section of the first water outlet hole 13 is in an elongated shape, for example, in a rectangular shape, or in a rounded rectangular shape, or in a diamond shape, etc. The boundary line between the bottom of the water outlet groove 32 and the first side surface 31 is a first boundary line 321, and the first boundary line 321 may be a straight line, a curved line, or a broken line. When the rotating member 3 rotates around the first axis, the first boundary line 321 also rotates around the first axis, so that the positional relationship between the first boundary line 321 and the first water outlet hole 13 is changed, for example, as shown in fig. 7, the projections of the first boundary line 321 and the first water outlet hole 13 on the first side surface 31 may be at least partially overlapped; or as shown in fig. 8, the first boundary line 321 is spaced from the projection of the first water outlet hole 13 on the first side surface 31. The coincidence here means that the first boundary line 321 is located in the projection, and when the first boundary line 321 is partially located in the projection; when fully coincident, the first boundary line 321 is fully within the projection. It will be appreciated that when spaced, the water outlet channel defined by the first water outlet aperture 13 and the water outlet channel 32 is defined by the first water outlet aperture 13; when partially overlapped, the water outlet passage is defined by the first water outlet hole 13 and the first boundary line 321. Therefore, when the projection of the first boundary 321 and the projection of the first water outlet hole 13 on the first side 31 are at least partially overlapped, and the first boundary 321 rotates around the first axis, the shape and the cross-sectional area of the water outlet channel are changed, so as to change the shape of the sprayed spray, and the sprayed spray can have various shapes.

In order to make the cross-sectional area of the water outlet passage as large as possible and to achieve the above-described effect that the water spray has various forms, the positions of the first boundary line 321 and the first water outlet hole 13 may be defined as follows: as shown in fig. 7, when the rotator 3 rotates to the first boundary 321 and the extending direction of the strip are parallel, the projection of the first water outlet hole 13 on the first side 31 is spaced from the first boundary 321; as shown in fig. 8, when the rotating member 3 rotates to the first boundary 321 perpendicular to the extending direction of the strip, the projection of the first water outlet hole 13 on the first side surface 31 coincides with at least a portion of the first boundary 321. Therefore, the first boundary line 321 is at least partially overlapped with the projection of the first water outlet hole 13 on the first side surface 31 only in part of time, so that the problem that the cross-sectional area of the water outlet channel is reduced due to the fact that the first boundary line 321 is always at least partially overlapped with the projection can be solved, and the problem that the sprayed water spray has various effects due to the fact that the first boundary line 321 is not overlapped with the projection can be solved.

Alternatively, the cross section of the first water outlet hole 13 is rectangular, the center of the rectangle is located on the first axis, and the distance between the first boundary line 321 and the first axis is equal to the distance between the long side of the rectangle and the first axis.

In fact, it is also possible that the two side walls 322 of the water outlet tank 32 may participate in defining the first water outlet hole 13 and the water outlet channel defined by the water outlet tank 32, for example, as shown in fig. 9, when the distance between the two side walls 322 of the water outlet tank 32 is smaller than the length of the cross section of the first water outlet hole 13, the side walls 322 of the water outlet tank 32 may overlap with the projection portion of the first water outlet hole 13 on the first side 31 when rotated to a certain angle, thereby reducing the cross section area of the water outlet channel. It will be appreciated that the side wall 322 of the water outlet channel 32 and the first boundary line 321 are respectively located in two mutually perpendicular directions of the first axis, so that the two are alternately engaged in defining the water outlet channel, which results in a reduced cross-sectional area of the water outlet channel, and thus it is necessary to avoid that the side wall 322 of the water outlet channel 32 is engaged in defining the water outlet channel. The side wall 322 of the water outlet trough 32 may be defined as follows: the side wall 322 of the water outlet groove 32 is spaced from the projection of the first water outlet hole 13 on the first side surface 31.

Optionally, the cross section of the first water outlet hole 13 is a rounded rectangle, the center of the rounded rectangle is located on the first axis, the distance between the side wall 322 of the water outlet groove 32 and the first axis is equal to the distance between the short side of the rounded rectangle and the first axis, and the distance between any point on the rounded rectangle and the first axis is smaller than or equal to the distance between the short side of the rounded rectangle and the first axis, so that the side wall 322 cannot appear in the projection of the first water outlet hole 13 on the first side surface 31.

In some embodiments, as shown in fig. 1, the casing 1 is further provided with a second water inlet hole 17 and a second water outlet hole 18, the second water outlet hole 18 is communicated with the second water inlet hole 17, and the second water outlet hole 18 and the first water outlet hole 13 are located on the same side of the casing 1. The second water outlet 18 is also used to spray water to increase the cleaning surface of the spray head 100.

In some embodiments, as shown in fig. 1, the casing 1 is further provided with a third water inlet hole 19 and a third water outlet hole 20, the third water outlet hole 20 is communicated with the third water inlet hole 19, and the third water outlet hole 20 and the first water outlet hole 13 are located on the same side of the casing 1. The third water outlet hole 20 is also used for spraying water to increase the cleaning surface of the spray head 100.

In some embodiments, as shown in fig. 1, the third water outlet hole 20 and the second water outlet hole 18 are respectively located at two sides of the first water outlet hole 13, so as to form a cleaning form that water spray is fixed at two sides of the middle water spray swing, which is beneficial to improving user experience.

In some embodiments, as shown in fig. 1, the first water inlet 12, the second water inlet 17 and the third water inlet 19 are provided on the same side of the housing 1 to facilitate connection of pipes.

In some embodiments, as shown in fig. 1, the third water outlet hole 20 is located on a side of the first water outlet hole 13 facing away from the third water inlet hole 19, and the second water outlet hole 18 is located on a side of the first water outlet hole 13 facing toward the second water inlet hole 17. Since the third water outlet hole 20 and the third water inlet hole 19 are far apart from each other, as shown in fig. 10, a flow passage 23 is further provided in the housing 1 for communicating the third water outlet hole 20 and the third water inlet hole 19.

In some embodiments, as shown in fig. 3, the housing 1 includes a first shell 21 and a second shell 22, the stopper 14 is disposed on the first shell 21, the shaft body 15 is disposed on the second shell 22, and the second shell 22 is detachably connected to the first shell 21.
