Detailed implementation manners

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting 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.

[0038] In the existing nozzles, each water inlet is located on a different water channel component. Cumulative errors will occur during the installation of the water channel components, resulting in a decline in the sealing performance of the joint between the water inlet and the spray gun.

[0039] Therefore, an embodiment of the present invention provides a nozzle 100, which can solve the problem of poor sealing between the water inlet of the existing nozzle and the joint of the spray gun.

[0040] Figure 1 It is a schematic structural diagram of the nozzle proposed in an embodiment of the present invention. Combining Figures 1 to 16 As shown, an embodiment of the present invention provides a nozzle 100, including an integrally formed transition water channel component 2. The transition water channel component 2 has a housing structure with an open top surface. The housing structure has a first side wall 202. A plurality of water inlets are provided on the first side wall 202. The plurality of water inlets are configured to allow multiple paths of water to enter different water channels respectively. A detachable rubber pad is provided on the end surface of the water inlet. The rubber pad is configured to seal and connect the end surface of the water inlet to the joint 501 of the spray gun.

[0041] The plurality refers to more than two. The nozzle 100 is fixedly connected by a plurality of components. The material of the components can be selected from plastics or metals. The fixed connection can be achieved by various methods (such as welding, gluing or screw fixing, etc., or any combination thereof). The nozzle 100 also has a spray pipe to eject the water in the water channel outward. Different flow paths of water channels are designed in each component, so that the water flow finally shoots out from one or more spray pipes. In one embodiment, a sealing groove is provided on the end surface of the water inlet, and the rubber pad can be adaptively installed in the sealing groove. The pipe where the water inlet is located penetrates through the rubber pad and corresponds to the through holes on the joint 501 one by one. The arrangement of the water inlets and the water channels connected thereto can be designed according to actual needs, and no specific limitation is made here.

[0042] In one embodiment, the end of the joint 501 near the water outlet is a plane, and the end surface of the water inlet is flush, saving occupied space.

[0043] According to the nozzle provided by the embodiment of the present invention, since a plurality of water inlets are all integrated on the first side wall of the transition water channel component, and the entire transition water channel component is integrally formed, and a detachable rubber pad is provided on the end surface of the water inlet, when the nozzle is connected to the joint of the spray gun, compared with the prior art where each water inlet is usually arranged on different components, cumulative errors occur during the installation of multiple components, and there are offset amounts in the positions of each water inlet. The pipe where the water inlet of the nozzle in the embodiment of the present invention is integrally formed, there is no cumulative installation error, and the sealing performance between the water inlet and the joint of the spray gun is better.

[0044] In some embodiments, the water inlet includes first to fourth water inlets (24, 25, 27, 29). The first water inlet 24 and the third water inlet 27 are located at the first end of the first side wall 202, and the second water inlet 25 and the fourth water inlet 29 are located at the second end of the first side wall 202. To achieve aesthetic appearance and space saving of the shape, the pipes where the first water inlet 24 and the third water inlet 27 are located are vertically stacked, and the pipes where the second water inlet 25 and the fourth water inlet 29 are located are vertically stacked. A guiding groove 6 is provided in the middle of the first side wall 202, that is, between the first end and the second end of the first side wall 202. Refer to Figure 16 , a protruding guiding block is provided on the plane of the joint 501 of the spray gun at the end close to the water outlet, and the guiding block is adapted to the guiding groove 6, so the two can be snap-connected together.

[0045] In addition, the transition water channel assembly 2 is provided with a second side wall 203. The second side wall 203 surrounds the transition water channel assembly 2, and both ends of the second side wall 203 are respectively connected to both ends of the first side wall 202. The height of the second side wall 203 is lower than the height of the first side wall 202. The top of the second side wall 203 is configured for the installation guiding of the bracket 600 of the spray gun. Specifically, refer to Figure 16 , a slideway 602 is provided on the inner wall of the bracket 600, and the top of the second side wall 203 can be slidably connected with the slideway, which is convenient for the disassembly of the nozzle 100. Guiding arms 7 are further provided on both sides of the transition water channel assembly 2, and an L-shaped clamping groove 603 is provided on the lower edge of the bracket 600. The guiding arms 7 can enter along the opening of the clamping groove 603 and be clamped with the clamping groove 603, and then a locking block (not shown in the figure) is inserted into the gap between the inner wall of the bracket 600 and the nozzle 100 to complete the detachable connection between the nozzle 100 and the bracket.

[0046] In some embodiments, the nozzle 100 further includes a bottom plate water channel assembly 3, and the bottom plate water channel assembly 3 is fixedly connected to the bottom of the transition water channel assembly 2. A plurality of anti-slip ridges 34 are provided on the bottom surface of the bottom plate water channel assembly 3. The anti-slip ridges 34 can increase the friction force with human fingers, and it is easier to install the nozzle 100 on the bracket 600 or remove the nozzle 100 from the bracket 600.

[0047] Combined with Figure 2 、 Figure 3 as described above, the nozzle 100 further includes a spraying assembly 1, an upper water channel assembly 4 and an upper water channel cover assembly 5. The bottom surface of the spraying assembly 1 is fixedly connected to the bottom surface inside the housing structure, that is, the upper part of the transition water channel assembly 2. The bottom surface of the upper water channel assembly 4 is fixedly connected to the upper part of the spraying assembly 1. The top surface of the upper water channel assembly 4 is fixedly connected to the bottom surface of the upper water channel cover assembly 5.

[0048] The injection assembly 1 is provided with an injection pipe 14. On both sides of the injection pipe 14, a first positioning protrusion 11 and a second positioning protrusion 13 are respectively provided. The upper water channel assembly 4 is provided with a first recess 46 adapted to the first positioning protrusion 11 and a second recess 47 adapted to the second positioning protrusion 13. In other words, the first positioning protrusion 11 can extend into the first recess 46, and the second positioning protrusion 13 can extend into the second recess 47, playing a limiting role.

[0049] Both ends of the upper water channel cover assembly 5 are provided with outer protrusions 52, and both ends of the upper water channel assembly 4 are provided with clamping portions 44 adapted to the outer protrusions 52. In other words, after the upper water channel assembly 4 and the upper water channel cover assembly 5 are combined, each clamping portion 44 can firmly clamp the corresponding outer protrusion 52, playing a limiting role.

[0050] The number of the injection pipes 14 can be set to one or more. At the same time, the injection pipes 14 can eject one or more water types, which can be designed according to actual needs.

[0051] In some embodiments, in combination Figure 2 、 Figure 3 As described above, the transition water channel assembly 2 is provided with a feces - assisting water injection pipe 21 and a retaining portion 201. One end of the injection assembly 1 is provided with a guiding notch 16 adapted to the feces - assisting water injection pipe 21, and the other end of the injection assembly 1 is provided with a protrusion 12 adapted to the retaining portion 201. In other words, the protrusion 12 can be stuck in the retaining portion 201, playing a limiting role. In one example, in order to increase the structural strength of the feces - assisting water injection pipe 21, a plurality of guiding ribs 212 are provided on the side wall of the feces - assisting water injection pipe 21. Correspondingly, a notch 161 is also provided inside the notch 16.

[0052] The middle part of the upper water channel assembly 4 is provided with a first opening 43, and the middle part of the upper water channel cover assembly 5 is provided with a second opening 51. After the components of the nozzle 100 are fixedly connected, the injection pipe 14 sequentially passes through the first opening 43 and the second opening 51, making the overall structure more compact.

[0053] Next, the nozzle of some specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0054] In combination Figures 1 to 16 As shown, the nozzle 100 according to an embodiment of the present invention includes an injection assembly 1, a transition water channel assembly 2, a bottom water channel assembly 3, an upper water channel assembly 4, and an upper water channel cover assembly 5 that are fixedly connected together. The transition water channel assembly 2 is provided with four integrally formed water inlets, namely the first to fourth water inlets (24, 25, 27, 29).

[0055] The water supply component 4 is provided with a first horizontal water channel 41 and a second horizontal water channel 42. On the bottom surfaces of both sides within the first horizontal water channel 41, a first inlet 411 and a first outlet 412 are respectively provided. On the bottom surfaces of both sides within the second horizontal water channel 42, a second inlet 421 and a second outlet 422 are respectively provided. A support bar 45 is further provided on the front surface of the water supply component 4 to serve as a bearing for the water supply cover component 5.

[0056] On the front surface of the injection component 1, a first upper water channel 18 and a second upper water channel 19 are provided. On the back surface, a side injection port flow channel 141 is provided. On the pipe wall of the injection pipe 14, a first pair of injection ports 131 and a second pair of injection ports 132 are provided. The first pair of injection ports 131 communicate obliquely downward with the first diversion pipe 1311, and the second pair of injection ports 132 communicate obliquely downward with the second diversion pipe 1321. At a lower position within the injection pipe 14, a vortex chamber 152 is provided. The top end of the vortex chamber 152 has an injection port 151, and the injection port 151 communicates with the injection pipe 14. The bottom end of the vortex chamber 152 has a bottom plate. The injection port 151 is located in the middle of the injection pipe 14, and the inner diameter of the injection port 151 is smaller than the inner diameter of the outlet 15 at the front end of the injection pipe 14. The shape of the vortex chamber 152 is similar to a cone. The top end of the vortex chamber 152 communicates with the injection port 151.

[0057] The transition water channel component 2 serves as the bottom plate of the vortex chamber 152, and through holes 23 are provided thereon. On the front surface of the transition water channel component 2, a third upper water channel 26 communicating with the third water inlet 27 and a fourth upper water channel 28 communicating with the fourth water inlet 29 are further provided. On the front surface of the transition water channel component 2, 22 is further provided. On the back surface of the transition water channel component 2, a first sewer 241 communicating with the first water inlet 24 and a second sewer 251 communicating with the second water inlet 25 are provided. The transition water channel component 2 further penetrates through and is provided with a fifth upper water channel 221 and a third sewer 219. The annular transition water channel 22 projects as an arc on the front surface of the transition water channel component 2, and this arc bypasses the area where the through holes 23 are located. The two ends of this arc are located below the first diversion pipe 1311 and the second diversion pipe 1321.

[0058] In the injection pipe 14 of the nozzle 100 in this embodiment, a first, a second, and a third outlet are integrated. The through holes 23 serve as the first outlet, and the number of the through holes 23 is designed according to actual needs. The function of the through holes 23 is to evenly divide the water in the water channel under the bottom plate of the vortex chamber 152 into several streams of water. These several streams of water intersect and converge after hitting the inclined surface of the vortex chamber 152, and turbulent water can be formed. The number of the second outlets is two, which are respectively the first pair of injection ports 131 and the second pair of injection ports 132. The third outlet is the intersection of the side injection port flow channel and the vortex chamber 152. The water flowing out from the third outlet can control the water flowing out from the through holes 23 to form spiral water.

[0059] Optionally, the number of the evenly distributed holes 23 is three. The inner diameters of the three evenly distributed holes 23 are the same, and the three evenly distributed holes 23 are rotationally symmetric along the axis of the injection pipe 14. This setting has a simple structure and is relatively easy to process.

[0060] The internal water channel of the nozzle 100 can be divided into a pipeline A, a pipeline B, a pipeline C, and a pipeline D. The pipeline A includes a first water inlet 24, a first sewer 241, a straight water transition channel 322, a first vertical turning channel 321, and an evenly distributed hole 23 (a first outlet). The pipeline B includes a second water inlet 25, a fan-shaped water inlet transition channel 31, a fifth upper channel 221, an annular transition channel 22, a first guide pipe 1311 and a second guide pipe 1321, a first pair of injection ports 131 and a second pair of injection ports 132 (a second outlet). The pipeline C includes a third water inlet 27, a third upper channel 26, a first inlet 411, a first lateral channel 41, a first outlet 412, a first upper channel 18, a side injection port flow channel 141, and an intersection of the side injection port flow channel and the vortex chamber 152 (a third outlet). The pipeline D includes a fourth water inlet 29, a fourth upper channel 28, a second inlet 421, a second lateral channel 42, a second outlet 422, a second upper channel 19, a third sewer 219, and a feces assisting water injection port 211.

[0061] Combined with Figure 2 、 Figure 3 and Figure 11 shown in the figure, when only the pipeline A conveys water, the three jets of water formed by the three evenly distributed holes are pressurized in the vortex chamber 152 and then form a linear water from the injection port 151 and are ejected from the outlet 15 of the injection pipe 14. The schematic diagram of the water pattern of the linear water is as shown in Figure 11 shown in the figure. The cross-sectional area of the water column of this water pattern is cylindrical, with a small cross-sectional area and great strength.

[0062] Combined with Figure 7 、 Figure 12 shown in the figure, when only the pipeline B conveys water, the two jets of water ejected from the first pair of injection ports 131 and the second pair of injection ports 132 collide with each other to form a fan-shaped particle water pattern, and the included angle F between the axes of the first guide pipe 1311 and the second guide pipe 1321 is different, so the opening angle of the formed fan shape is also different. By adjusting the flow rates of the first pair of injection ports 131 and the second pair of injection ports 132, the larger the flow rates of the two pairs of injection ports, the larger the fan angle. The fan expansion angle can be dynamically adjusted by adjusting the water outlet flow rate, and thus the cleaning area can be dynamically adjusted to meet the needs of users for different cleaning areas. And due to the full sense of particles, it has a self-impact massage effect.

[0063] Combined with Figure 7 、 Figure 13As shown, when water is simultaneously transported through pipeline A and pipeline B, fan-shaped sheet water will be formed. After pipeline B forms the basic fan-shaped granular water pattern, 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 linear water flow rate, the lower the granulation degree. When the linear water flow rate reaches a certain level, under a certain water outlet stroke, the intersecting water pattern is mainly a sufficient sheet water pattern. The linear water through pipeline A can reduce the fan-shaped water outlet angle and increase the softness of the water.

[0064] Combined with Figure 2 、 Figure 3 、 Figure 14 As shown, when water is simultaneously transported through pipeline A and pipeline C, the water flows of these two pipelines rotate in the vortex chamber 152 and then are pressurized and sprayed from the spray port 151. Due to the pressure release after ejection, the spiral surrounding water will be shaped into a certain shaped hollow surrounding water against the inner wall above the spray port 151 of the spray pipe 14 under the centrifugal action and then ejected from the ejection port 15, with a cyclone spiral sheet water pattern. This kind of cyclone spiral sheet water pattern has a fast surrounding speed and is equivalent to continuously colliding with the body surface along the ring. 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. Under the cyclone spiral sheet water pattern, the first pair of injection ports 131, the first guide pipe 1311, the annular transition water channel 22, the second guide pipe 1321 and the second pair of injection ports 132 form a dynamic balance circulation pipeline. A small part of the spiral surrounding water pressurized and sprayed from the spray port 151 will enter the internal circulation pipeline from the first pair of injection ports 131 or the second pair of injection ports 132 and then be ejected from the first pair of injection ports 131 or the second pair of injection ports 132, forming a dynamic balance and compensating the cyclone spiral sheet water pattern. When the water flow rate is too large, this dynamic balance pipeline can absorb a part of the water flow to avoid excessive spiral shape. When the flow rate is too small, the water flow rate in the dynamic balance circulation pipeline decreases, and the shape of the cyclone spiral sheet water pattern can still maintain the required standard.

[0065] Combined with Figure 7 、 Figure 15 As shown, the inner diameter of the feces assistance water spray pipe 21 is gradually reduced in stages and the overall length of the feces assistance water spray pipe 21 is relatively long. Therefore, when only pipeline D transports water, the concentration of the feces assistance water ejected from the feces assistance water spray port 211 is very high, and the design of a small aperture with a large flow rate of water makes the ejection speed of the water column relatively high, which can effectively stimulate the anal sphincter and improve constipation.

[0066] The nozzle with a single spray pipe integrating multiple ejection ports provided by the embodiment of the present invention shows only four basic water patterns. When cooperating with electric controllers such as water pumps, air pumps, and electromagnetic pumps, more water patterns can be changed based on the original four basic water patterns, and combined with the electric control program, different massage and stimulation effects can be achieved.

[0067] When the nozzle 100 of the embodiment of the present invention is installed, the joint 501 is connected to the joint pipe fitting 502 on the side away from the nozzle 100, and the joint 501 is stuck in two installation grooves 601 on the inner wall of the bracket 600. The top of the second side wall 203 on the nozzle 100 is slidably connected to the slideway 602. The guiding arm 7 of the nozzle 100 can enter along the opening of the clamping groove 603 and be clamped with the clamping groove 603. The protruding guiding block on the joint 501 extends into the guiding groove 6 on the nozzle 100, and the rubber pad is sealed with the joint 501 to complete the connection between the nozzle 100 and the joint 501. It can be seen that the nozzle 100 of the embodiment of the present invention can be disassembled from the bracket of the spray gun, realizing the convenience of nozzle maintenance.
