Description

Technical Field

[0001] The present invention relates to the technical field of sanitary wares, and particularly to a nozzle and a control method thereof. Background Art

[0002] An intelligent toilet, also known as an electronic toilet seat or a smart toilet seat, is a toilet combined with intelligent technology and controlled by a microcomputer, generally having functions such as warm water washing, warm air drying, and seat heating. Common intelligent toilets are divided into integrated intelligent toilets and split intelligent toilets. The warm water flushing function is the core function of an intelligent toilet. The warm water flushing function is realized by a spray gun for spraying water.

[0003] In the prior art, a nozzle is provided on the spray gun, and the nozzle shoots out water flow towards the cleaning part.

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: the sitting postures of toilet users are different. If a user wants the water flow shot out by the nozzle to accurately clean a specific part, such as the anus, the user needs to deliberately adjust the sitting posture, such as bending the body or moving the hips left and right. Adjusting the sitting posture will affect the user experience. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0006] For this purpose, the object of the present invention is to provide a nozzle and a control method thereof, which can realize the cleaning of specific body parts without the user adjusting the sitting posture.

[0007] To achieve the above object, a first aspect of the present invention provides a nozzle, comprising:

[0008] At least one injection tube, the injection tube having an outlet, the injection tube being used for shooting out different water flows, the inner surface of the injection tube having a first counter jet part and / or a second counter jet part, the first counter jet part being used for spraying out a first fan-shaped water from the outlet, and the second counter jet part being used for spraying out a second fan-shaped water from the outlet;

[0009] A plurality of water inlets, the water inlets being communicated with the injection tube through water channels, the water inlets being used for injecting water flows with adjustable flow rates, and the first fan-shaped water or the second fan-shaped water deflects with the adjustment of the water flow rate.

[0010] According to the nozzle of the present invention, by providing the first pair of injection parts and / or the second pair of injection parts, fan-shaped water located in different planes can be ejected, thereby enabling the water flow ejected by the nozzle to have a larger coverage area, forming a larger cleaning area, and having a good cleaning effect. By adjusting the water flow at the water inlet of the nozzle of the present invention, the fan-shaped water can be deflected. After adjustment, the water flow can accurately align with a specific body part for cleaning, and the user does not need to adjust their sitting posture, thus obtaining a better experience.

[0011] According to an embodiment of the present invention, the first pair of injection parts includes a first injection port and a second injection port, and the axes of the first injection port and the second injection port intersect with the axis of the injection pipe; the second pair of injection parts includes a third injection port and a fourth injection port, and the axes of the third injection port and the fourth injection port intersect with the axis of the injection pipe.

[0012] According to an embodiment of the present invention, the first injection port and the second injection port are symmetrically arranged on both sides of the injection pipe, and the third injection port and the fourth injection port are symmetrically arranged on both sides of the injection pipe.

[0013] According to an embodiment of the present invention, the plane where the axes of the first injection port and the second injection port are located is orthogonal to the first plane, where the first plane is the plane where the first injection port and the second injection port inject equal-flow water and eject the first fan-shaped water.

[0014] According to an embodiment of the present invention, the axes of the third injection port and the fourth injection port are orthogonal to the second plane, where the second plane is the plane where the third injection port and the fourth injection port inject equal-flow water and eject the second fan-shaped water.

[0015] A second aspect of the present invention provides a control method for a nozzle, including:

Among them, the first injection port and the second injection port are provided on the inner surface of an injection pipe, the injection pipe has an outlet, and the first injection port and the second injection port are symmetrically arranged on both sides of the injection pipe;

[0017] Adjust the water flow injected into the first injection port and the second injection port. If the water injected into the first injection port and the second injection port has equal flow, the first injection port and the second injection port eject the first fan-shaped water from the outlet. At this time, the plane where the first fan-shaped water is located is in the first plane; if the water injected into the first injection port and the second injection port does not have equal flow, the first fan-shaped water deflects towards the side of the injection port with a smaller water flow.

[0018] According to the control method of the nozzle of the present invention, by adjusting the water flow rates injected into the first pair of injection ports and the second pair of injection ports, the fan-shaped water ejected by the nozzle can be deflected, that is, the position can be adjusted, so that the water flow can accurately align with a specific body part for cleaning, enabling the user to obtain a better experience without adjusting the sitting posture.

[0021] Adjust the water flow rates injected into the third pair of injection ports and the fourth pair of injection ports. If the water flow rates injected into the third pair of injection ports and the fourth pair of injection ports are equal, the third pair of injection ports and the fourth pair of injection ports eject second fan-shaped water from the outlet, and at this time, the plane where the second fan-shaped water is located is in the second plane; if the water flow rates injected into the third pair of injection ports and the fourth pair of injection ports are not equal, the second fan-shaped water deflects towards the side of the injection port with a smaller water flow rate.

[0022] According to an embodiment of the present invention, the first plane and the second plane intersect.

[0023] According to an embodiment of the present invention, the case where if the water flow rates injected into the first pair of injection ports and the second pair of injection ports are not equal, the first fan-shaped water deflects towards the side of the injection port with a smaller water flow rate includes:

Detailed implementation manners

[0053] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0054] Intelligent toilets generally have a spray gun, which can be controlled to extend and retract relative to the intelligent toilet body. The nozzle on the spray gun can spray a water pattern for cleaning, and the user can use the sprayed water pattern for cleaning.

[0055] However, the sitting postures of toilet users are different. If the user wants the water flow ejected from the nozzle to accurately clean a specific part, such as the anus or the female private part, the user needs to deliberately adjust the sitting posture, such as bending the body or moving the hips left and right. Adjusting the sitting posture will affect the user experience.

[0056] For this reason, the present invention proposes a nozzle 100 that can adjust the position of the sprayed water pattern without relying on the movement of the spray gun, improving the user experience.

[0057] Combined with Figures 1 to 15 As shown, a first aspect of the embodiment of the present invention proposes a nozzle 100. The nozzle 100 includes a plurality of water inlets and at least one injection pipe 111. The water inlets are used to inject water flows with adjustable flow rates. Optionally, the water inlets can be connected to a water distribution valve (not shown in the figure), and the water distribution valve can control the water flow rate entering the nozzle 100 and can also control its water outlet timing.

[0058] The injection pipe 111 has an outlet 11. The injection pipe 111 is communicated with the water inlets through water channels. The injection pipe 111 is used to eject different water flows. The inner surface of the injection pipe has a first counter-jet part and / or a second counter-jet part. That is to say, the first counter-jet part and the second counter-jet part can be respectively arranged in different injection pipes, or the first counter-jet part and the second counter-jet part can be simultaneously arranged in one injection pipe 111.

[0059] Combined with Figures 11 to 15 、 Figure 17 As shown, the first counter-jet part can eject a first fan-shaped particle water (hereinafter referred to as fan-shaped water) located in the first plane β from the outlet 11, and the second counter-jet part can eject a second fan-shaped water located in the second plane α from the outlet 11. The first plane β and the second plane α intersect; the first fan-shaped water or the second fan-shaped water deflects with the adjustment of the water flow rate. Specifically, the first fan-shaped water deflects along the B axis, and the deflection direction is determined by the water flow difference in the first counter-jet 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 counter-jet part. Wherein the A axis and the B axis intersect and are both parallel to the plane where the outlet 11 is located.

[0060] It should be noted that the first pair of jet parts and the second pair of jet parts work alternately. When the first pair of jet parts are working, the second pair of jet parts do not discharge water, and vice versa.

[0061] For the spray head according to the embodiment of the present invention, by providing the first pair of jet parts and / or the second pair of jet parts, fan-shaped water on different planes can be sprayed, thereby enabling the water flow sprayed by the spray head to cover a larger area, forming a larger cleaning area, and having a good cleaning effect. By adjusting the water flow at the water inlet of the spray head of the present invention, the plane where the fan-shaped water is located can be deflected. After adjustment, the water flow can be accurately aligned with a specific body part for cleaning, and the user does not need to adjust the sitting posture, obtaining a better experience.

[0062] An embodiment of the spray head 100 in which the first pair of jet parts and the second pair of jet parts are integrated in the same jet pipe 111 will be described below with reference to the accompanying drawings.

[0063] Combined Figures 1 to 15 As shown, the spray head 100 can be disassembled into a jet assembly 1, a transition water channel assembly 2, a bottom plate water channel assembly 3, a first side water channel assembly 4, and a second side water channel assembly 5 from the processing process. Each component is connected by welding. Optionally, each component is integrally connected by ultrasonic welding. The bottom plate water channel assembly 3 is located at the bottommost part of the spray head 100. The transition water channel assembly 2 is arranged above the bottom plate water channel assembly 3, and a first water diversion channel 21, a second water diversion channel 22, and an equalization hole 23 are arranged on the transition water channel assembly 2. The jet assembly 1 is arranged above the transition water channel assembly 2, and the jet pipe 111 is arranged above the jet assembly 1. The first side water channel assembly 4 and the second side water channel assembly 5 are arranged above the jet assembly 1 and on the same side of the jet pipe 111.

[0064] 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. Among them, the first water inlet 19 is arranged on the jet assembly 1. The second water inlet 24, the third water inlet 25, and the fourth water inlet 26 are arranged on the transition water channel assembly 2. The fifth water inlet 41 is arranged on the first side water channel assembly 4. The sixth water inlet 51 is arranged on the second side water channel assembly.

[0065] The positions of each water inlet can be designed according to actual needs. As an example, the six water inlets are located on the same side of the spray head 100.

[0066] In order to spray more diverse water patterns, a first outlet and a second outlet are also arranged in the jet pipe of the spray head 100. The axis of the first outlet coincides with the jet pipe 111, and the axis of the second outlet is separated from the center of the jet pipe 111. The first outlet is used to form a linear water flow, and the second outlet is used to form a rotating water flow.

[0067] The first pair of jetting parts includes a first jetting port 131 and a second jetting port 132. The axes of the first jetting port 131 and the second jetting port 132 intersect with the axis of the jetting pipe 111. The second pair of jetting parts includes a third jetting port 141 and a fourth jetting port 142. The axes of the third jetting port 141 and the fourth jetting port 142 intersect with the axis of the jetting pipe 111. When the water jets from the first jetting port 131 and the second jetting port 132 collide with each other, a first fan-shaped water will be formed. Similarly, when the water jets from the third jetting port 141 and the fourth jetting port 142 collide with each other, a second fan-shaped water will be formed.

[0068] According to the configuration of the outlet and the jetting parts, the internal water channels of the nozzle 100 can be divided into six paths: A pipeline, B1 pipeline, B2 pipeline, C1 pipeline, C2 pipeline and D pipeline. The A pipeline is connected to the fourth water inlet 26 and the first outlet; the B1 pipeline is connected to the second water inlet 24 and the first jetting port 131; the B2 pipeline is connected to the third water inlet 25 and the second jetting port 132; the C1 pipeline is connected to the sixth water inlet 51 and the third jetting port 141; the C2 pipeline is connected to the fifth water inlet 41 and the fourth jetting port 142; the D pipeline is connected to the first water inlet 19 and the second outlet.

[0069] In one example, the first jetting port 131 and the second jetting port 132 are symmetrically arranged on both sides of the jetting pipe 111, and the third jetting port 141 and the fourth jetting port 142 are symmetrically arranged on both sides of the jetting pipe 111. If the water flow rates in the first jetting port 131 and the second jetting port 132 are equal, the plane where the axes of the first jetting port 131 and the second jetting port 132 are located is orthogonal to the first plane β. If the water flow rates in the third jetting port 141 and the fourth jetting port 142 are equal, the axes of the third jetting port 141 and the fourth jetting port 142 are orthogonal to the second plane α. When the first jetting port 131 and the second jetting port 132 inject water with equal flow rates, the first plane β is orthogonal to the cross-section of the outlet 11. When the third jetting port 141 and the fourth jetting port 142 inject water with equal flow rates, the second plane α is orthogonal to the cross-section of the outlet. Optionally, the included angle between the first plane β and the second plane α is 90°. If the water flow rates in the two jetting ports 131 and 132 in the first pair of jetting parts are inconsistent, the first fan-shaped water will deflect towards the jetting port with a smaller water flow rate. Similarly, the second fan-shaped water deflects towards the jetting port with a smaller water flow rate.

[0070] In one example, in combination with Figure 4 、 Figure 6As shown, the fourth water inlet 26 of the nozzle 100 serves as a linear water inlet, and a vortex chamber 17 is provided in the injection pipe 111. The shape of the vortex chamber 17 is similar to a conical cavity. The top end of the vortex chamber 17 has an injection port 12, and the injection port 12 communicates with the injection pipe 111. The bottom end of the vortex chamber 17 is fixed to the transition water channel assembly 2. The injection port 12 is located in the middle of the injection pipe 111, and the inner diameter of the injection port 12 is smaller than the inner diameter of the outlet 11 at the front end of the injection pipe 111. The injection port 12 functions to converge the water flow. The first outlet is the equalizing hole 23. The equalizing hole 23 is located at the bottom end of the vortex chamber 17. The number of the equalizing holes 23 is at least one, and the number of the equalizing holes is designed according to actual needs. In an embodiment where there are multiple equalizing holes 23, the function of the equalizing holes 23 is to divide the water in the water channel under the bottom plate of the vortex chamber 17 into several strands of water. These several strands of water intersect and converge after hitting the inclined surface of the vortex chamber 17, and turbulent water can be formed, which is easily controlled by the water discharged from the second outlet to form spiral water. Optionally, the number of the equalizing holes 23 is 3. The inner diameters of the 3 equalizing holes 23 are the same, and the 3 equalizing holes 23 are rotationally symmetric along the axis of the injection pipe 111. This setting has a simple structure and is relatively easy to process. When the second outlet does not discharge water, the 3 strands of water formed by the 3 equalizing holes are pressurized in the vortex chamber 17, and linear water is formed from the injection port 12 and ejected from the outlet 11 of the injection pipe 111. Refer to Figure 16 For this type of water column, the cross-sectional area is cylindrical, with a small cross-sectional area and great strength.

[0071] In one embodiment, the A pipeline includes a straight water transition water channel 322, a first vertical turning water channel 321, the equalizing hole 23, and the vortex chamber 17 that are connected in sequence. Among them, the straight water transition water channel 322 and the first vertical turning water channel 321 are integrated and located on the bottom plate water channel assembly 3. The first vertical turning water channel 321 is a cylindrical cavity, and the projection of the equalizing hole 23 on the bottom plate water channel assembly 3 is located within this cylindrical cavity.

[0072] In one example, the B1 pipeline includes a fourth water diversion channel 33, a second water diversion channel 22, and a first diversion pipeline 1311 that are connected in sequence. Among them, the fourth water diversion channel 33 is provided on the bottom plate water channel assembly 3 and is arranged separately from the straight water transition water channel 322. The second water diversion channel 22 is provided on the transition water channel assembly 2. The first diversion pipeline 1311 is provided on the injection assembly 1. The B2 pipeline includes a third water diversion channel 31, a first water diversion channel 21, and a second diversion pipeline 1321 that are connected in sequence. Among them, the third water diversion channel 31 is provided on the bottom plate water channel assembly 3 and is arranged separately from the straight water transition water channel 322. The first water diversion channel 21 is provided on the transition water channel assembly 2. The first water diversion channel 21 and the second water diversion channel 22 are respectively arranged on both sides of the equalizing hole 23. The first diversion pipeline 1311 is provided on the injection assembly 1 and forms an angle with the injection pipe 111.

[0073] By adjusting the water flow rates in the first pair of injection ports 131 and the second pair of injection ports 132, the larger the water flow rates of the two pairs of injection ports, the larger the fan angle. The fan-shaped expansion angle can be dynamically adjusted by adjusting the water flow rate of the discharged water, and thus the cleaning area will be dynamically adjusted, which can meet the needs of users for different cleaning areas. Moreover, due to the plump particle feeling, it has a self-impacting massage effect.

[0074] The C1 pipeline includes a second vertical water channel port 52, a U-shaped water channel 15, a third vertical water channel port 151, and a third diversion pipeline 1411 that are connected in sequence. The second vertical water channel port 52 is arranged on the second side water channel assembly 5. The overall structure of the second side water channel assembly 5 is U-shaped. A rubber scooping groove is arranged at the top of the second side water channel assembly 5, which is convenient for the manufacturing and demolding of the nozzle. The U-shaped water channel 15 is arranged on the injection assembly 1 and surrounds the injection pipe 111. The third vertical water channel port 151 penetrates through the injection assembly 1. The third diversion pipeline 1411 is arranged on the injection assembly 1 and forms an angle with the injection pipe 111.

[0075] The C2 pipeline includes a first vertical water channel port 42, a fourth vertical water channel port 152, and a fourth diversion pipeline 1421 that are connected in sequence. The first vertical water channel port 42 is arranged on the first side water channel assembly 4. The fourth vertical water channel port 152 penetrates through the injection assembly 1. The fourth diversion pipeline 1421 is arranged on the injection assembly 1 and forms an angle with the injection pipe 111.

[0076] The D pipeline includes a vortex chamber 17. The second outlet serves as a side injection port 16, and the side injection port 16 is arranged on the inner wall of the vortex chamber 17. Optionally, for the convenience of processing, the side injection port 16 intersects with the upper surface of the bottom plate of the vortex chamber 17. The water flow flowing out from the first water inlet 19 enters the vortex chamber 17, and due to the restriction of the inner wall of the vortex chamber 17, the water flow is forced to make a rotational motion.

[0077] Combined Figure 6 、 Figure 18 As shown, if water flows are injected into the A pipeline, the B1 pipeline, and the B2 pipeline simultaneously, a fan-shaped sheet of water will be formed. After the B1 and B2 pipelines form the basic fan-shaped particle water pattern, by combining with the linear water of the A pipeline, the three-column water intersects, and the granulation degree of the fan-shaped particle water can be controlled. The larger the linear water flow rate, the lower the granulation degree. When the linear water flow rate reaches a certain level, within a certain discharged water stroke, the intersecting water pattern is mainly a plump sheet of water. The linear water of the A pipeline can reduce the fan-shaped discharged water angle and increase the softness of the water. Similarly, if water flows are injected into the A pipeline, the C1 pipeline, and the C2 pipeline simultaneously, another fan-shaped sheet of water will be formed, and the working principle is the same as above.

[0078] Combined Figure 6 、 Figure 19As shown in the figure, if water flows are injected into pipelines A and D simultaneously, spiral surrounding water will be formed in the vortex chamber 17. The water flows in these two pipelines rotate in the vortex chamber 17 and then are pressurized and ejected from the ejection port 12. Due to the pressure release after ejection, the spiral surrounding water will form a shaped hollow surrounding water against the shaping port 18 under the action of centrifugal force and then be ejected from the ejection port 11, ejecting in the form of a thin sheet of water with a cyclone spiral shape. Here, the shaping port 18 is the inner wall of the ejection pipe 111 above the ejection port 12. This kind of thin sheet of water with a cyclone spiral shape has a fast surrounding speed and quite continuously collides with the body surface along the ring shape. While ensuring the cleaning area, it has a self - massage impact effect. Pipeline D can control the spiral degree, and pipeline A can control the concentration degree.

[0079] The nozzle with a single ejection pipe integrating multiple ejection ports provided by the embodiment of the present invention shows only three basic water types. When cooperating with electric controllers such as water pumps, air pumps, and electromagnetic pumps, more water types can be varied based on the original three basic water types. And combined with the electric control program, different massage stimulation effects can be achieved. By integrating the three water types into one ejection pipe, users can enjoy the three water types without using a spray gun, meeting the need for cleaning variation of the same part of the human body under the premise of unchanged position. By continuously switching two or more water types through control methods such as controlling different frequencies, a better massage effect can be achieved.

[0080] Figure 20 It is a schematic flow chart of the control method of the nozzle proposed by the embodiment of the present invention. Combining Figures 1 to 20 As shown in the figure, in the second aspect of the embodiment of the present invention, a control method of a nozzle is proposed, and the implementation process of this method is as follows:

[0081] Step S102, inject water into the first pair of ejection ports 131 and the second pair of ejection ports 132. Among them, the first pair of ejection ports 131 and the second pair of ejection ports 132 are arranged on the inner surface of an ejection pipe 111. The ejection pipe 111 has an ejection port 11, and the first pair of ejection ports 131 and the second pair of ejection ports 132 are symmetrically arranged along both sides of the ejection pipe 111.

[0082] In this embodiment, the first pair of ejection ports 131 and the second pair of ejection ports 132 are connected to different water inlets through water channels.

[0083] Step S104, if the water flows injected into the first pair of ejection ports 131 and the second pair of ejection ports 132 are of equal flow rate, the first pair of ejection ports 131 and the second pair of ejection ports 132 eject the first fan - shaped water from the ejection port 11. At this time, the plane where the first fan - shaped water is located is in the first plane; if the water flows injected into the first pair of ejection ports 131 and the second pair of ejection ports 132 are of unequal flow rate, the first fan - shaped water deflects towards the side of the ejection port with a smaller water flow rate.

[0084] In this embodiment, combining Figure 6 、 Figure 11 andFigure 14 As shown, when the water injected into the first pair of injection ports 131 and the second pair of injection ports 132 has the same flow rate, the first plane β is perpendicular to the plane where 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 where the outlet 11 is located. When the water injected into the first pair of injection ports 131 and the second pair of injection ports 132 has a non-uniform flow rate, the first fan-shaped water deflects along the B axis. The B axis is parallel to the plane where the outlet 11 is located. The deflection direction of the first fan-shaped water is determined by the difference in the water flow rates in the first pair of injection ports 131 and the second pair of injection ports 132. For example, in combination with Figure 6 、 Figure 11 and Figure 15 As shown, when the water flow rate in the second pair of injection ports 132 is greater than the water flow rate in the first pair of injection ports 131, the first fan-shaped water deflects to the side of the first pair of injection ports 131. At this time, the position of the first fan-shaped water is on the plane β'. If you want the first fan-shaped water to deflect in the opposite direction, just adjust the water flow rate in the second pair of injection ports 132 to be less than the water flow rate in the first pair of injection ports 131.

[0085] According to the control method of the nozzle in the embodiment of the present invention, by adjusting the flow rates of the water injected into the first pair of injection ports and the second pair of injection ports, the fan-shaped water ejected from the nozzle can deflect, that is, the position is adjustable, so that the water flow can accurately align with a specific body part for cleaning, thereby enabling the user to obtain a better experience without adjusting the sitting posture.

[0086] In one example, the control method of the nozzle further includes:

[0087] Step S106, injecting water into the third pair of injection ports 141 and the fourth pair of injection ports 142, wherein the third pair of injection ports 141 and the fourth pair of injection ports 142 are arranged on the inner surface of a spray pipe 111, and the third pair of injection ports 141 and the fourth pair of injection ports 142 are symmetrically arranged along both sides of the spray pipe 111.

[0088] In this embodiment, the third pair of injection ports 141 and the fourth pair of injection ports 142 are connected to different water inlets through water channels. The positions of the third pair of injection ports 141 and the fourth pair of injection ports 142 can be designed according to actual needs.

[0089] Step S108, if the water injected into the third pair of injection ports 141 and the fourth pair of injection ports 142 has the same flow rate, the third pair of injection ports 141 and the fourth pair of injection ports 142 eject the second fan-shaped water from the outlet 11. At this time, the plane where the second fan-shaped water is located is in the second plane; if the water injected into the third pair of injection ports 141 and the fourth pair of injection ports 142 has a non-uniform flow rate, the second fan-shaped water deflects to the side of the injection port with a smaller water flow rate.

[0090] In this embodiment, in combination with Figure 7 、 Figure 11 and Figure 12As shown, when the water injected from the third pair of injection ports 141 and the fourth pair of injection ports 142 has the same flow rate, the second plane α is perpendicular to the plane where the axes of the third pair of injection ports 141 and the fourth pair of injection ports 142 are located, and the second plane α is perpendicular to the cross-section of the outlet 11. When the water injected from the third pair of injection ports 141 and the fourth pair of injection ports 142 has a non-uniform flow rate, the second fan-shaped water deflects along the A axis. The A axis is parallel to the plane where the outlet 11 is located. The deflection direction of the second fan-shaped water is determined by the difference in the water flow rates in the third pair of injection ports 141 and the fourth pair of injection ports 142. For example, in combination with Figure 7 , Figure 11 As shown, when the water flow rate in the third pair of injection ports 141 is greater than the water flow rate in the fourth pair of injection ports 142, the second fan-shaped water deflects to the side of the fourth pair of injection ports 142. At this time, the position of the second fan-shaped water is on the plane α'. Referring to Figure 13 As shown, if you want the second fan-shaped water to deflect in the opposite direction, just adjust the water flow rate in the third pair of injection ports 141 to be less than the water flow rate in the fourth pair of injection ports 142. At this time, the position of the second fan-shaped water is on the plane α''.

[0091] The first plane β and the second plane α intersect. In one embodiment, the first plane β and the second plane α are perpendicular, and the fan-shaped water ejected from the nozzle can sweep a larger area through deflection.

[0092] Adjust the water flow rates injected into the first pair of injection ports 131 and the second pair of injection ports 132 in step S104. If the water injected into the first pair of injection ports 131 and the second pair of injection ports 132 has a non-uniform flow rate, the first fan-shaped water deflects to the side of the injection port with a smaller water flow rate. Specifically, it includes:

[0093] Gradually change the water flow rates injected into the first pair of injection ports 131 and the second pair of injection ports 132, so that the first fan-shaped water deflects 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 the first fan-shaped water deflects 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.

[0094] Combined with a specific application scenario, such as Figure 21 As shown, control the water flow rates injected into the first pair of injection ports 131 and the second pair of injection ports 132. The ejected first fan-shaped water scans back and forth on the front and back sides of the buttocks. Combined with the movement of the spray gun, the nozzle outlet, that is, the outlet 11, can be moved to a suitable position to wash the female private parts or anus.

[0095] Adjust the water flow rates injected into the third pair of injection ports and the fourth pair of injection ports in step S108. If the water injected into the third pair of injection ports 141 and the fourth pair of injection ports 142 has a non-uniform flow rate, the second fan-shaped water deflects to the side of the injection port with a smaller water flow rate. Specifically, it includes:

[0096] Gradually change the water flow rates injected into the third pair of injection ports 141 and the fourth pair of injection ports 142, so that the second fan-shaped water deflects 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 the second fan-shaped water deflects 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.

[0097] Combined with a specific application scenario, such as Figure 22 As shown, by controlling the water flow rates injected into the third pair of injection ports 141 and the fourth pair of injection ports 142, the ejected second fan-shaped water can be adjusted between the left and right sides of the buttocks. When the user has a sitting posture with a left or right deviation, without getting up, the deflection angle of the fan-shaped water can be adjusted to achieve alignment with the body part to be cleaned, obtaining a better cleaning effect.

[0098] It can be understood that both the deflection angle and the deflection timing of the fan-shaped water can be set.

[0099] In summary, the beneficial effects of the control method of the nozzle in this embodiment are as follows:

[0100] First, the control method of the nozzle in the embodiment of the present invention can infinitely adjust the water outlet angle of the fan-shaped water. After the spray gun moves to the specified gear, by triggering the water type deflection function, the ejection angle can be adjusted, enabling users with different sitting posture habits to adjust the water type corner to make the water flow align with the anus for cleaning without deliberately bending the body.

[0101] Second, for female users, due to the actual angle difference between the female private part position and the anus position, the water outlet of the current market spray guns is basically at a fixed water outlet angle, resulting in a poor experience for female users. However, the fan-shaped water outlet angle in the embodiment of the present invention can be infinitely adjusted, better achieving the cleaning of the required cleaning angle of the female private part.

[0102] Third, the embodiment of the present invention solves the problem that when the user has a sitting posture with a left or right deviation, without getting up, the water outlet angle can be adjusted to achieve lower body cleaning.
