Detailed implementation mode

[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described 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 that fall within the spirit and scope of the appended claims.

[0040] In the existing intelligent toilet seat or intelligent toilet, the water pattern ejected by a single nozzle is single and cannot meet the cleaning needs of various parts of the human body.

[0041] For this reason, the embodiments of the present invention propose a sprinkler head 1000, a spray gun, an intelligent toilet seat, and an intelligent toilet, which can eject multiple water patterns from the same sprinkler head and improve the user experience.

[0042] Combined with Figures 1 to 15 As shown, a first aspect of the embodiments of the present invention proposes a sprinkler head 1000. The sprinkler head 1000 includes: at least one water inlet and at least one injection pipe 18. The water inlet is used to connect to a water distribution valve (not shown in the figure), and the water distribution valve can perform timing control on the water output of the injection pipe 18.

[0043] The injection pipe 18 is connected to the water inlet through a water channel, and the water channel is located inside the sprinkler head 1000. The inner surface of the injection pipe 18 has a first outlet and / or a second outlet and / or a third outlet. The axis of the first outlet is parallel to the axis of the injection pipe 18, the axis of the second outlet intersects the axis of the injection pipe 18, and the axis of the third outlet is separated from the center of the cross - section of the injection pipe 18. Under different combinations of outlets, the injection pipe 18 can eject different types of water flows.

[0044] The setting method of the outlet can be designed according to actual needs. For example, a spray pipe 18 can be provided with only the first outlet, or the second outlet, or the third outlet. A spray pipe 18 can also be provided with any two of the three outlets. Of course, a spray pipe 18 can also be provided with the first outlet, the second outlet and the third outlet at the same time.

[0045] According to different configurations of the outlets, the internal water channels of the spray head 1000 can be divided into three paths: path A, path B, and path C. Path A is connected between an inlet and the first outlet; path B is connected between another inlet and the second outlet; path C is connected between yet another inlet and the third outlet.

[0046] It can be understood that the number of spray pipes 18 on the spray head 1000 is set according to actual needs. The outlets of path A, path B, and path C can be integrated in the same spray pipe 18, or located in three different spray pipes 18 respectively, or integrated in two or more spray pipes 18 in any combination. The combination methods are diverse and can well meet the needs of customized users. No matter how they are combined, these spray pipes 18 are arranged adjacent to each other, reducing the space occupied by the spray gun.

[0047] In one embodiment, the axis of the first outlet coincides with the axis of the spray pipe 18, that is, the axis of the second outlet intersects the axis of the first outlet. If path A and path B discharge water simultaneously, the two water flows intersect, and the water discharged from path A can control the degree of granulation of the discharged water.

[0048] According to the spray head of the embodiment of the present invention, by providing outlets pointing in different directions on the inner surface of the spray pipe, on the premise of limited space, the pipeline structure is simplified, the volume is reduced, the manufacturing cost is lowered, the combination methods of the outlets are diverse, and various water patterns can be ejected, improving the user experience.

[0049] The applicant has found that the spray guns in the prior art adopt a multi-nozzle split-hole design, and the length of the spray gun is relatively long, and the stroke of the spray gun is also correspondingly extended to spray the water from the water outlet holes at a relatively far distance onto the user's body surface. It cannot meet the requirement of continuously cleaning and changing the same part of the human body under the premise of unchanged position, affecting the user experience.

[0050] Therefore, an embodiment of the spray head 1000 in which the first, second, and third outlets are integrated in the same spray pipe 18 will be described below with reference to the accompanying drawings.

[0051] Combined with Figures 1 to 15As shown in the figure, the nozzle 1000 can be disassembled from top to bottom into a spraying component 100, a transition water channel component 200, a bottom plate water channel component, and a side water channel component 400. The spraying component 100, the transition water channel component 200, the bottom plate water channel component, and the side water channel component 400 are welded into one body. The spray pipe 18 is located on the spraying component 100.

[0052] In one example, the water inlet of the nozzle 1000 includes a first water inlet, and the first water inlet serves as a direct water inlet 24. A vortex chamber 15 is provided in the spray pipe 18. The top end of the vortex chamber 15 has a spray port 12, and the spray port 12 communicates with the spray pipe 18. The bottom end of the vortex chamber 15 has a bottom plate. The spray port 12 is located in the middle of the spray pipe 18, and the inner diameter of the spray port 12 is smaller than the inner diameter of the outlet 11 at the front end of the spray pipe 18. The lower end of the spray port 12 is provided with a vortex chamber 15. The shape of the vortex chamber 15 is similar to a cone. The top end of the vortex chamber 15 communicates with the spray port 12, and a number of evenly distributed holes 23 are provided through the bottom plate of the vortex chamber 15. The evenly distributed holes 23 communicate with the direct water inlet 24 through a water channel, and the evenly distributed holes 23 serve as the first outlet. The number of the evenly distributed holes 23 is designed according to actual needs. The function of the evenly distributed holes 23 is to evenly divide the water in the water channel under the bottom plate of the vortex chamber 15 into several strands of water. These several strands of water intersect and converge after hitting the inclined surface of the vortex chamber 15, and turbulent water can be formed, which is easy to be controlled by the water outlet of the third outlet to form spiral water. Optionally, the number of the evenly distributed holes 23 is 3. The inner diameters of the 3 evenly distributed holes 23 are the same, and the 3 evenly distributed holes 23 are rotationally symmetric along the axis of the spray pipe 18. This setting has a simple structure and is relatively easy to process. When the third outlet does not discharge water, the 3 strands of water formed by the 3 evenly distributed holes are pressurized in the vortex chamber 15 and then form a linear water from the spray port 12 and are ejected from the outlet 11 of the spray pipe 18. The water pattern schematic diagram of the linear water is as Figure 11 shown. The cross-sectional area of the water column of this water pattern is cylindrical, with a small cross-sectional area and great strength.

[0053] In one embodiment, the A pipeline includes a direct water transition water channel 322, a first vertical turning water channel 321, and a vortex chamber 15 that are connected in sequence. The direct water transition water channel 322 communicates with the direct water inlet 24. The direct water transition water channel 322 and the first vertical turning water channel 321 are both located on the bottom plate water channel component 300. The first vertical turning water channel 321 is a cylindrical cavity, and the projection of the evenly distributed holes 23 on the bottom plate water channel component 300 is located within the cross-section of the cylindrical cavity.

[0054] In one example, the water inlet of the spray head 1000 includes a second water inlet, and the second water inlet is a fan-shaped water inlet 22. The number of the second outlet ports is two, namely a first pair of opposite jets 131 and a second pair of opposite jets 132. A first diversion pipe 1311 communicates with the rear end of the first pair of opposite jets 131, and a second diversion pipe 1321 communicates with the rear end of the second pair of opposite jets 132. The first diversion pipe 1311 and the second diversion pipe 1321 are symmetrically arranged along both sides of the spray pipe 18, and the rear ends of the first diversion pipe 1311 and the second diversion pipe 1321 are communicated with the fan-shaped water inlet 22 through a water channel. Combined with Figure 10 and Figure 12 As shown, when the water jets from the first pair of opposite jets 131 and the second pair of opposite jets 132 collide with each other, a fan-shaped particle water pattern will be formed. And with different axial angles F of the first diversion pipe 1311 and the second diversion pipe 1321, the opening angles of the formed fans are also different. By adjusting the flow rates of the first pair of opposite jets 131 and the second pair of opposite jets 132, the larger the flow rates of the two pairs of opposite jets, the larger the fan angle. The fan opening angle can be dynamically adjusted by adjusting the water outlet flow rate, and the cleaning area can be dynamically adjusted accordingly, which can meet the user's requirements for different cleaning areas. And due to the plump particle feeling, it has a self-impact massage effect.

[0055] In one embodiment, the first pair of opposite jets 131 and the second pair of opposite jets 132 are located on the inner wall side of the spray pipe 18, and the positions of these two pairs of opposite jets are higher than the position of the spray orifice 12. The B pipeline includes a fan-shaped water inlet transition water channel 31, an annular transition water channel 21, a first diversion pipe 1311 and a second diversion pipe 1321 that are connected in sequence. The fan-shaped water inlet transition water channel 31 communicates with the fan-shaped water inlet 22. The bottom of the annular transition water channel 21 has an annular transition water channel water inlet 211, and the annular transition water channel 21 and the fan-shaped water inlet transition water channel 31 are communicated through the annular transition water channel water inlet 211. The fan-shaped water inlet transition water channel 31 is located on the bottom plate water channel assembly 300, the annular transition water channel 21 is located on the transition water channel assembly 200, and the first diversion pipe 1311 and the second diversion pipe 1321 are both located on the spray assembly 100. The projection of the annular transition water channel 21 on the front of the transition water channel assembly 200 is an arc, and this arc bypasses the area where the equalizing holes 23 are located, and the two ends of this arc are located below the first diversion pipe 1311 and the second diversion pipe 1321.

[0056] Combined with Figure 10 and Figure 13As shown, when water is sprayed out from both pipeline A and pipeline B simultaneously, fan-shaped sheet water will be formed. After the basic fan-shaped granular water pattern is formed by pipeline B, by combining with the linear water of pipeline A, the intersection of the three columns of water can control the granulation degree of the fan-shaped granular water. The greater the flow rate of the linear water, the lower the granulation degree. When the flow rate of the linear water reaches a certain level, within a certain water outlet stroke, the intersecting water pattern is mainly a sufficient sheet water pattern. The linear water of pipeline A can reduce the fan-shaped water outlet angle and increase the softness of the water.

[0057] In one example, the water inlet of the nozzle 1000 includes a third water inlet, the third water inlet is a side injection water inlet 142, the third outlet is a side injection port 14, and the side injection port 14 is arranged on the inner wall of the vortex chamber 15. Optionally, for the convenience of processing, the side injection port 14 intersects with the upper surface of the bottom plate of the vortex chamber 15. The rear end of the side injection port 14 is communicated with the side injection water inlet 142 through a water channel. The water flow flowing out from the side injection water inlet 142 enters the vortex chamber 15, and due to the restriction of the inner wall of the vortex chamber 15, the water flow is forced to make a rotational movement.

[0058] In one embodiment, pipeline C includes a side injection port flow channel 141. The side injection port flow channel 141 is respectively communicated with the side injection water inlet 142 and the side injection water inlet 142, and the side injection port flow channel 141 is located on the injection assembly 100. Figure 9 and Figure 14 As shown, when water is sprayed out from both pipeline A and pipeline C simultaneously, spiral surrounding water will be generated. The water flows of these two pipelines rotate in the vortex chamber 15 and then are pressurized and sprayed from the injection port 12. Due to the pressure release after ejection, the spiral surrounding water will form a certain shaped hollow surrounding water against the shaping port 17 under the centrifugal action and then be ejected from the ejection port 11, and is ejected in the form of a cyclone spiral sheet water pattern, where the shaping port 17 is the inner wall of the injection pipe 18 above the injection port 12. This kind of cyclone spiral sheet water pattern has a fast surrounding speed, which is equivalent to continuously colliding with the body surface along the ring shape. Under the condition of ensuring the cleaning area, it has a self - massage impact effect. Pipeline C can control the spiral degree, and pipeline A can control the concentration degree.

[0059] In addition, in order to further increase the function of spraying assisting defecation water, in one example, the nozzle 1000 further includes an assisting defecation water injection pipe 26. The assisting defecation water injection pipe 26 has an assisting defecation water injection port 25. The water inlet includes an assisting defecation water inlet 411, and the rear end of the assisting defecation water injection port 25 is communicated with the assisting defecation water inlet 411 through pipeline D. The inner wall of the assisting defecation water injection pipe 26 is a guiding section 251. Along the water flow direction, the inner diameter of the guiding section 251 gradually decreases in stages. Through the design of lengthening the guiding section 251 of the assisting defecation water injection pipe 26, it is ensured that the concentration of the assisting defecation water is very high, and with a small aperture design and a large - flow water flow, the ejection speed of the ejected water column is relatively high, which can effectively stimulate the anal sphincter and improve the constipation situation.

[0060] In one embodiment, the D pipeline includes a feces-softening water transition water channel 41, a second vertical water turning port 16, a third vertical water turning port 253, and a transition water channel 252 that are connected in sequence. The feces-softening water transition water channel 41 communicates with a feces-softening water inlet 411, and the transition water channel 252 communicates with a feces-softening water injection port 25. The feces-softening water transition water channel 41 is located on the side water channel assembly 400, the second vertical water turning port 16 penetrates through the injection assembly 100, the third vertical water turning port 253 penetrates through the transition water channel assembly 200, the transition water channel 252 is located at the bottom of the transition water channel assembly 200, and both ends of the transition water channel 252 connect the third vertical water turning port 253 and a guiding section 251. A through hole 19 is provided on the injection assembly 100, and a feces-softening water injection pipe 26 passes through the through hole 19. The axis of the feces-softening water injection pipe 26 is parallel to the axis of the injection pipe 18.

[0061] The nozzle of the single injection pipe integrating multiple outlet ports provided by the embodiment of the present invention only shows four basic water types. When cooperating with electric controllers such as water pumps, air pumps, and electromagnetic pumps, more water types can be changed under the original four basic water types. And combined with the electric control program, different massage stimulation effects can be achieved. By integrating three water types into one injection pipe, users can enjoy three water types without using a spray gun, meeting the needs of changing the cleaning of the same part of the human body without changing the position. By controlling different frequencies and other control methods to continuously switch between two or three water types, a better massage effect can be achieved.

[0062] Based on the above object, the second aspect of the embodiment of the present invention provides a spray gun, including a gun barrel and the nozzle as described in the first aspect above, and the nozzle is arranged inside the gun barrel.

[0063] The third aspect of the embodiment of the present invention provides a smart toilet seat, including a toilet seat body and the spray gun as described in the second aspect above. The spray gun is arranged on the toilet seat body and can be telescopic relative to the toilet seat body.
