Adjusting the sitting position may affect the user's experience.

Therefore, the present invention provides a spray head 100, which can adjust the position of water spray without moving a spray gun, thereby improving the user experience.

Referring to fig. 1 to 15, a first aspect of an embodiment of the present invention proposes a spray head 100. The spray head 100 includes a plurality of water inlets and at least one spray tube 111. The water inlet is used for injecting water flow with adjustable flow. Optionally, the water inlet may be connected to a diverter valve (not shown) that controls the flow of water into the spray head 100, as well as the timing of the water outlet.

Specifically, the first fan-shaped water deflects along the B-axis, and the deflection direction is determined by the difference in water flow in the first correlation part. The second fan-shaped water deflects along the A axis, and the deflection direction is determined by the water flow difference in the second correlation part. Wherein the axis a and the axis B intersect and are both parallel to the plane of the exit opening 11.

It should be noted that the first correlation part and the second correlation part are alternatively operated. The first opposite-shooting part works while the second opposite-shooting part does not discharge water, and vice versa.

According to the spray head provided by the embodiment of the invention, the fan-shaped water positioned on different planes can be sprayed out by arranging the first opposite-spraying part and/or the second opposite-spraying part, so that the water flow sprayed out of the spray head can be larger in coverage area, a larger cleaning area can be formed, and the cleaning effect is good. According to the shower nozzle, the plane where the fan-shaped water is located can deflect by adjusting the water flow of the water inlet, the water flow can be accurately aligned to a specific body part for cleaning after adjustment, a user does not need to adjust sitting postures, and better experience is obtained.

An embodiment of the sprinkler 100 in which the first and second correlation portions are integrated in the same sprinkler tube 111 is described below with reference to the accompanying drawings.

As shown in connection with fig. 1 to 15, the spray head 100 may be split from the manufacturing process into a spray assembly 1, a transition waterway assembly 2, a floor waterway assembly 3, a first side waterway assembly 4, and a second side waterway assembly 5. The components are connected by welding. Optionally, the individual components are integrally connected by ultrasonic welding. The floor waterway assembly 3 is located at the very bottom of the sprinkler 100. The transition water channel assembly 2 is arranged above the bottom plate water channel assembly 3, and a first drainage water channel 21, a second drainage water channel 22 and an equally-dividing hole 23 are arranged on the transition water channel assembly 2. The spray assembly 1 is arranged above the transition water channel assembly 2 and the spray pipe 111 is arranged above the spray assembly 1. The first side waterway assembly 4 and the second side waterway assembly 5 are disposed above the spray assembly 1 on the same side of the spray tube 111.

The spray head 100 is designed with six water inlets, namely a first water inlet 19, a second water inlet 24, a third water inlet 25, a fourth water inlet 26, a fifth water inlet 41 and a sixth water inlet 51. Wherein the first water inlet 19 is arranged on the jetting assembly 1. A second water inlet 24, a third water inlet 25 and a fourth water inlet 26 are provided on the transitional waterway assembly 2. A fifth water inlet 41 is provided on the first side waterway assembly 4. A sixth water inlet 51 is provided on the second side waterway assembly.

The positions of the water inlets can be designed according to actual needs. As one example, six inlets are located on the same side of the spray head 100.

In order to spray more various water types, a first outlet and a second outlet are further provided in the spray pipe of the spray head 100. The axis of the first outlet coincides with the injection tube 111, and the axis of the second outlet is separated from the center of the injection tube 111. The first exit opening is used for forming linear water, and the second exit opening is used for forming rotary water flow.

The first shot portion includes a first shot hole 131 and a second shot hole 132, and the axes of the first shot hole 131 and the second shot hole 132 intersect with the axis of the injection tube 111. The second shot portion includes a third shot hole 141 and a fourth shot hole 142, and the axes of the third shot hole 141 and the fourth shot hole 142 intersect with the axis of the injection tube 111. The two water outlets of the first and second pairs of jet ports 131 and 132 collide with each other to form a first fan-shaped water, and the two water outlets of the third and fourth pairs of jet ports 141 and 142 collide with each other to form a second fan-shaped water.

Depending on the configuration of the outlet and the counter-jet, the internal water passage of the sprinkler head 100 can be divided into 6 paths: pipeline A, pipeline B1, pipeline B2, pipeline C1, pipeline C2 and pipeline D. The pipeline A is communicated with the fourth water inlet 26 and the first outlet; b1 pipeline is communicated with the second water inlet 24 and the first pair of injection ports 131; b2 pipeline is communicated with the third water inlet 25 and the second shot hole 132; the C1 pipeline is communicated with the sixth water inlet 51 and the third injection port 141; the C2 pipeline is communicated with the fifth water inlet 41 and the fourth shot hole 142; the pipeline D is communicated with the first water inlet 19 and the second outlet.

In one example, the first and second pairs of injection ports 131 and 132 are symmetrically arranged along both sides of the injection tube 111, and the third and fourth pairs of injection ports 141 and 142 are symmetrically arranged along both sides of the injection tube 111. If the water flows in the first and second pairs of injection ports 131 and 132 are equal, the plane in which the axes of the first and second pairs of injection ports 131 and 132 are located is orthogonal to the first plane β. If the water flow rates in the third and fourth pairs of injection ports 141 and 142 are equal, the axes of the third and fourth pairs of injection ports 141 and 142 are orthogonal to the second plane α. When the first and second pairs of jet ports 131 and 132 inject equal flow rates of water, the first plane β is orthogonal to the cross section of the outlet port 11. When the third and fourth pairs of jet ports 141 and 142 inject equal flow rates of water, the second plane α is orthogonal to the cross section of the jet ports. Optionally, the first plane β forms an angle of 90 with the second plane α. If the water flows in the two opposite openings 131, 132 in the first opposite opening are not uniform, the first fan-shaped water is deflected to the opposite opening side with smaller water flow. Similarly, the second fan-shaped water deflects to one side of the opposite jet port with smaller water flow.

In one example, as shown in fig. 4 and 6, the fourth water inlet 26 of the spray head 100 is a linear water inlet, and the swirl chamber 17 is provided in the spray pipe 111. The vortex chamber 17 is shaped like a cone. The top end of the vortex cavity 17 is provided with an injection port 12, the injection port 12 is communicated with an injection pipe 111, and the bottom end of the vortex cavity 17 is fixed with the transition water channel assembly 2. The injection port 12 is located in the middle of the injection tube 111, and the inside diameter of the injection port 12 is smaller than the inside diameter of the exit port 11 at the front end of the injection tube 111. The jet ports 12 function to concentrate the water flow. The first outlet is an equipartition hole 23. The equipartition hole 23 is located at the bottom end of the swirl chamber 17. The number of the equipartition holes 23 is at least one, and the number of the equipartition holes is designed according to actual needs. In the embodiment with a plurality of equipartition holes 23, the equipartition holes 23 are used for equally dividing the water in the sewer under the bottom plate of the vortex cavity 17 into a plurality of strands of water, and the strands of water meet the inclined plane of the vortex cavity 17 and then meet to form turbulent water, so that the turbulent water is easy to be controlled by the water discharged from the second outlet to form spiral water. Alternatively, the number of the equipartition holes 23 is 3, the inner diameters of the 3 equipartition holes 23 are consistent, the 3 equipartition holes 23 are rotationally symmetrical along the axis of the injection tube 111, and the arrangement structure is simple and the processing is easier. When the second outlet does not discharge water, 3 strands of water formed by the 3 uniform holes are pressurized in the vortex chamber 17, and then the linear water is formed from the injection port 12, and the linear water is discharged from the outlet 11 of the injection pipe 111. Referring to fig. 16, the cross-sectional area of the water column of this type is cylindrical, and the cross-sectional area is small and the force is large.

In one embodiment, the A pipeline comprises a straight water transition water channel 322, a first vertical water diversion channel 321, an equipartition hole 23 and a vortex cavity 17 which are communicated in sequence. Wherein the straight water transition waterway 322 is integrally connected to the first vertical transfer waterway 321, and is positioned on the floor waterway assembly 3. The first vertical water transfer channel 321 is a cylindrical cavity in which the projection of the uniform distribution holes 23 on the soleplate water channel assembly 3 is located.

In one example, the B1 pipeline includes a fourth drainage channel 33, a second drainage channel 22, and a first drainage channel 1311, which are in sequential communication. Wherein the fourth drainage waterway 33 is disposed on the floor waterway assembly 3, and is disposed apart from the straight water transition waterway 322. A second drainage waterway 22 is disposed on the transition waterway assembly 2. A first diversion conduit 1311 is provided on the jetting assembly 1. The B2 pipeline comprises a third drainage channel 31, a first drainage channel 21 and a second drainage pipeline 1321 which are communicated in sequence. Wherein the third drainage waterway 31 is disposed on the floor waterway assembly 3, spaced apart from the straight water transition waterway 322. A first drainage waterway 21 is disposed on the transition waterway assembly 2. The first drainage channel 21 and the second drainage channel 22 are respectively arranged at two sides of the equipartition hole 23. The first guide tube 1311 is disposed on the spray assembly 1 at an angle to the spray tube 111.

Through adjusting the water flow in the first pair of jet ports 131 and the second pair of jet ports 132, the larger the two pairs of jet port flow is, the larger the fan-shaped angle is, the fan-shaped expansion angle can be dynamically adjusted by adjusting the water outlet flow, the cleaning area can be dynamically adjusted, the requirements of users on different cleaning areas can be met, and the impact massage effect is achieved due to full granular feel.

The C1 pipeline includes a second vertical water passage 52, a U-shaped water passage 15, a third vertical water passage 151, and a third diversion pipe 1411, which are sequentially communicated. Wherein a second vertical water passage opening 52 is provided in the second side water passage assembly 5. The second side water channel component 5 has a U-shaped overall structure. The top of the second side water channel component 5 is provided with a glue drawing groove which is convenient for manufacturing and demoulding of the spray head. A U-shaped water channel 15 is provided on the spray assembly 1 around the spray tube 111. A third vertical water passage opening 151 is provided penetrating the spray assembly 1. A third deflector pipe 1411 is provided on the spray assembly 1 at an angle to the spray tube 111.

The C2 pipeline includes a first vertical water port 42, a fourth vertical water port 152, and a fourth diversion pipeline 1421, which are sequentially communicated. Wherein a first vertical water passage opening 42 is provided in the first side water passage assembly 4. A fourth vertical water passage opening 152 is provided throughout the spray assembly 1. A fourth flow conduit 1421 is provided on the injection assembly 1 at an angle to the injection tube 111.

The D line includes a swirl chamber 17. The second exit port serves as a side-injection port 16, the side-injection port 16 being provided on the inner wall of the swirling chamber 17. Alternatively, for ease of machining, the side jet 16 intersects the upper surface of the floor of the scroll chamber 17. The water flow from the first inlet 19 enters the vortex chamber 17 and is forced to perform a rotational movement due to the restriction of the inner wall of the vortex chamber 17.

Referring to fig. 6 and 18, if the water flows are simultaneously injected into the a, B1 and B2 pipes, fan-shaped sheet water is formed. After the pipelines B1 and B2 form the basic fan-shaped particle water type, the granulation degree of the fan-shaped particle water can be controlled by matching the linear water of the pipeline A and the intersection of three columns of water, and the granulation degree is lower as the linear water flow is larger. When the linear water flow reaches a certain degree, under a certain water outlet stroke, the intersected water type is the water type with abundant flaky water as the main water type. The linear water passing through the pipeline A can reduce the fan-shaped water outlet angle and increase the flexibility of water. Similarly, if the water flow is injected into the pipeline A, the pipeline C1 and the pipeline C2 simultaneously, another fan-shaped flaky water is formed, and the working principle is the same as that described above.

As shown in fig. 6 and 19, if the water flow is injected simultaneously into the line a and the line D, spiral water is formed in the vortex chamber 17. The water flows of these two lines are rotated in the swirl chamber 17 and then pressurized and injected from the injection port 12. Due to the release of pressure after the emergence, the spiral surrounding water is formed into a shaped hollow surrounding water by the centrifugal effect and then is ejected from the emergence opening 11, and the shaped hollow surrounding water is emergent in a cyclone spiral sheet water type, wherein the shaping opening 18 is the inner wall of the ejector tube 111 above the ejection opening 12. The cyclone spiral flake water type impact device has high surrounding speed, is quite capable of continuously impacting the body surface along a ring shape, and has a massage impact effect under the condition of ensuring the cleaning area. The pipeline D can control the spiral degree, and the pipeline A can control the concentration degree.

The spray head with the single spray pipe provided by the embodiment of the invention integrated with a plurality of spray outlets displays three basic water types, and can change more water types under the original three basic water types by matching with the electric controllers such as the water pump, the air pump, the electromagnetic pump and the like, and can realize different massage stimulation effects by combining with an electric control program. The three water types are integrated in the one injection pipe, so that a user can enjoy the three water types without receiving the spray gun, and the requirement of cleaning and changing the same part of the human body on the premise of unchanged position is met. By controlling different frequencies and other control modes to continuously switch two or more water types, better massage effect can be achieved.

Fig. 20 is a flowchart of a method for controlling a spray head according to an embodiment of the present invention. Referring to fig. 1 to 20, a second aspect of an embodiment of the present invention provides a method for controlling a spray head, where the method includes the following implementation procedures:

in step S102, water is injected into the first and second pairs of injection ports 131 and 132, wherein the first and second pairs of injection ports 131 and 132 are disposed on the inner surface of one injection tube 111, the injection tube 111 has one exit port 11, and the first and second pairs of injection ports 131 and 132 are symmetrically disposed along both sides of the injection tube 111.

In the present embodiment, the first and second pairs of injection ports 131 and 132 are communicated to different water inlets through waterways.

Step S104, if the water injected from the first pair of injection ports 131 and the second pair of injection ports 132 has equal flow rate, the first pair of injection ports 131 and the second pair of injection ports 132 emit first fan-shaped water from the exit port 11, and at this time, the plane of the first fan-shaped water is located in the first plane; if the water injected from the first and second ports 131 and 132 is not equal in flow rate, the first fan-shaped water is deflected toward the port side where the flow rate of the water is small.

In the present embodiment, as shown in fig. 6, 11 and 14, when the water injected from the first pair of injection ports 131 and the second pair of injection ports 132 flows at equal rates, the first plane β is perpendicular to the plane in which the axes of the first pair of injection ports 131 and the second pair of injection ports 132 are located, and the first plane β is perpendicular to the plane in which the exit port 11 is located. When the water injected from the first and second pairs of injection ports 131 and 132 is not equal in flow rate, the first fan-shaped water is deflected along the B axis. The B axis is parallel to the plane of the exit 11. The direction of deflection of the first fan water is determined by the difference in water flow rates in the first and second pairs of jet ports 131 and 132. For example, as shown in connection with fig. 6, 11 and 15, when the water flow rate in the second pair of jet ports 132 is greater than the water flow rate in the first pair of jet ports 131, the first fan-shaped water is deflected to one side of the first pair of jet ports 131 while the position of the first fan-shaped water is on the plane β'. If it is desired that the first fan of water be biased in the opposite direction, the water flow in the second pair of jet ports 132 may be adjusted to be less than the water flow in the first pair of jet ports 131.

According to the control method of the spray head, provided by the embodiment of the invention, the fan-shaped water injected by the spray head can deflect, namely the position is adjustable, by adjusting the flow of the water injected by the first opposite injection port and the second opposite injection port, so that the water flow is accurately aligned to a specific body part for cleaning, a user does not need to adjust the sitting posture, and better experience is obtained.

In one example, the method for controlling a spray head further includes:

in step S106, water is injected into the third and fourth pairs of injection ports 141 and 142, wherein the third and fourth pairs of injection ports 141 and 142 are disposed on the inner surface of one injection tube 111, and the third and fourth pairs of injection ports 141 and 142 are symmetrically disposed along both sides of the injection tube 111.

In this embodiment, the third and fourth pairs of jet ports 141 and 142 are connected to different water inlets through waterways. The positions of the third and fourth pairs of injection ports 141 and 142 may be designed according to actual needs.

Step S108, if the flow rate of the water injected by the third pair of injection ports 141 and the fourth pair of injection ports 142 is equal, the third pair of injection ports 141 and the fourth pair of injection ports 142 emit second fan-shaped water from the exit port 11, and the plane of the second fan-shaped water is located at the second plane; if the water injected from the third and fourth pairs of injection ports 141 and 142 is not equal in flow rate, the second fan-shaped water is deflected toward the opposite injection port side where the flow rate of the water is small.

In the present embodiment, as shown in fig. 7, 11 and 12, when the water injected from the third and fourth pairs of injection ports 141 and 142 flows at equal rates, the second plane α is perpendicular to the plane in which the axes of the third and fourth pairs of injection ports 141 and 142 are located, and the second plane α is perpendicular to the cross section of the exit port 11. When the water injected from the third and fourth pairs of injection ports 141 and 142 is not equal in flow rate, the second fan-shaped water is deflected along the A-Axis. The A-Axis is parallel to the plane of the exit opening 11. The direction of deflection of the second fan water is determined by the difference in water flow rates in the third and fourth pairs of jet ports 141 and 142. For example, as shown in fig. 7 and 11, when the water flow rate in the third pair of jet ports 141 is greater than the water flow rate in the fourth pair of jet ports 142, the second fan-shaped water is deflected to one side of the fourth pair of jet ports 142, and the position of the second fan-shaped water is on the plane α'. Referring to fig. 13, if it is desired that the second fan-shaped water be biased in the opposite direction, the water flow rate in the third pair of injection ports 141 is adjusted to be smaller than the water flow rate in the fourth pair of injection ports 142, and the position of the second fan-shaped water is on the plane α″.

The first plane β and the second plane α are in an intersecting relationship. In one embodiment, the first plane beta and the second plane alpha are perpendicular, and fan-shaped water emitted by the spray head can sweep a larger area through deflection.

In step S104, the flow rate of the water injected into the first and second pairs of injection ports 131 and 132 is adjusted, and if the flow rates of the water injected into the first and second pairs of injection ports 131 and 132 are not equal, the first fan-shaped water is deflected to the side of the opposite injection port with smaller flow rate, specifically including:

the water flow rate of the injection of the first and second pairs of injection ports 131 and 132 is changed stepwise so that the first fan-shaped water is deflected from the side where the first pair of injection ports 131 is located to the side where the second pair of injection ports 132 is located or so that the first fan-shaped water is deflected from the side where the second pair of injection ports 132 is located to the side where the first pair of injection ports 131 is located.

In combination with a specific application scenario, as shown in fig. 21, the water flow injected by the first pair of injection ports 131 and the second pair of injection ports 132 is controlled, the sprayed first fan-shaped water scans back and forth on the front side and the rear side of the buttocks, and the water outlet of the spray nozzle, namely the injection port 11, can be moved to a proper position by combining with the movement of the spray gun, so that the private parts or anus of women can be cleaned.

In step S108, the flow rates of water injected from the third and fourth pairs of injection ports are adjusted, and if the flow rates of water injected from the third and fourth pairs of injection ports 141 and 142 are not equal, the second fan-shaped water is deflected to the side of the opposite injection port with smaller flow rate, specifically including:

the water flow rate of the injection of the third and fourth pairs of injection ports 141 and 142 is changed stepwise so that the second fan-shaped water is deflected from the side where the third pair of injection ports 141 is located to the side where the fourth pair of injection ports 142 is located or so that the second fan-shaped water is deflected from the side where the fourth pair of injection ports 142 is located to the side where the third pair of injection ports 141 is located.

In combination with a specific application scenario, as shown in fig. 22, the water flow injected by the third pair of injection ports 141 and the fourth pair of injection ports 142 is controlled, the sprayed second fan-shaped water can be adjusted between the left side and the right side of the buttocks, the problem that under the condition that the sitting posture of a user deviates left and right is solved, the user does not need to lift the body, the deflection angle of the fan-shaped water is adjusted, the aim of aiming at the body part to be cleaned is achieved, and a better cleaning effect is obtained.

It will be appreciated that both the angle of deflection and the timing of deflection of the fan water may be provided.

In summary, the control method of the spray head of the embodiment has the following beneficial effects:

1. according to the control method of the spray head, the fan-shaped water outlet angle can be adjusted in a stepless manner, after the spray gun moves to a designated gear, the water type deflection function is triggered, the injection angle can be adjusted, users with different sitting postures can use the water type rotation angle adjusting function, and the purpose that water flow is aimed at anus for cleaning is achieved under the condition that the users do not need to bend bodies intentionally.

2. For female users, the actual angles of the private parts and the anus positions of the females are different, so that the water outlet angle of the spray gun in the market is basically a fixed water outlet angle, and the female experience is poor.

3. The embodiment of the invention solves the problem that the lower body can be cleaned by adjusting the water outlet angle without lifting the body under the condition of left and right deviation of the sitting position of the user.
