DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0040] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0041] like Figure 1-8 A nozzle includes a nozzle body and an adjustment kit. The nozzle body comprises a fixedly assembled first gripping shell 101 and a tube body 102. The tube body 102 is adapted to introduce water flow and comprises a connecting pipe section 103, a main body section 104, a screw-on section 105, and an inner spray section 106, which are sequentially arranged. The inner spray section 106 is provided with a plurality of circumferentially arranged first inner water outlets 107. The first gripping shell 101 is adapted to cover the main body section 104. The adjustment kit comprises a pipe head 201, a screw-on sleeve 203, and a second gripping shell 204. The second gripping shell 204 is adapted to cover portions of the pipe head 201 and the screw-on sleeve 203. The pipe head 201 includes a water outlet end surface 205 and an inner cylinder 208 and an outer cylinder extending axially from the water outlet end surface 205. The inner cylinder 208 and the screw-on sleeve 203 are axially connected to form a direct spray channel 210 and a plurality of circumferentially evenly distributed second inner water outlets 214. The direct spray channel 210 is provided with an outer cylinder along the axial direction of the adjustment sleeve. The inner cylinder 208 and the screw-on sleeve 203 together form an annular diffused water channel 211 arranged around the direct spray channel 210. The direct spray channel 210 includes a first water spray section 212 and a second water spray section 213. The first water spray section 212 includes a direct spray outlet 206. The second water spray section 213 is connected to the annular diffused water channel 211 through the second inner water outlet 214. The water outlet end surface 205 is formed with a straight nozzle 206 corresponding to the first water spray section 212 and an annular diffusion nozzle 207 corresponding to the annular diffusion water channel 211. The annular diffusion nozzle 207 includes a plurality of evenly distributed water outlet holes 215. The radial size of the water outlet holes 215 gradually shrinks from the inside to the outside, which can further pressurize the water flow.

[0042] Furthermore, the annular diffusion nozzle 207 extends outwardly along its axial direction to form a coaxially arranged inner guide wall 216 and outer guide wall 217 , which provide axial guidance and radial limitation for the water flow ejected from the annular diffusion nozzle 207 .

[0043] In this embodiment, the end of the inner nozzle section 106 is connected to a guide column 108. The guide column 108 includes a trumpet-shaped first guide platform 109 and a cylindrical second guide platform 110, which are arranged in sequence. The open end of the first guide platform 109 completely overlaps with the end of the second guide platform 110. The straight nozzle 206 extends outward to form a trumpet-shaped first guide groove 218, and the straight nozzle 206 extends inward to form a cylindrical second guide groove 219.

[0044] In this embodiment, the inner spray section 106 is formed with a stopper 111, which is disposed at the junction of the inner spray section 106 and the guide post 108. The stopper 111 is adapted to seal the end of the first guide groove 218 facing away from the straight nozzle 206, thereby shutting off the nozzle. The stopper 111 has a truncated cone structure, and the end of the first guide groove 218 is formed with a trumpet-shaped curved surface that fits snugly into the stopper 111, ensuring a reliable seal. The design of the stopper 111 allows the user to easily open and close the nozzle, providing dynamic adjustment of the water flow.

[0045] In this embodiment, the end of the inner spray section 106 facing the screw-on section 105 is equipped with a first sealing ring 112. The first sealing ring 112 and the second water spray section 213 are sealingly slidably engaged to limit water leakage from the inner spray section 106. A second sealing ring 220 is disposed between the first water spray section 212 and the second water spray section 213. The second sealing ring 220 and the inner spray section 106 are sealingly slidably engaged to limit communication between the first water spray section 212 and the second water spray section 213. Furthermore, the second sealing ring 220 can move to abut the first water spray section 212. The distance between the second sealing ring 220 and the first inner water outlet 107 is suitable for limiting the displacement distance of the inner spray section 106.

[0046] In this embodiment, the nozzle body and the adjustment kit are threadedly matched so that the two can approach or move away from each other in the axial direction. Specifically, the outer peripheral surface of the screw-on section 105 is formed with an external thread 113, and the screw-on sleeve 203 includes an internal thread 221 suitable for matching the external thread 113. The internal thread 221 is suitable for limiting the relative movement distance between the nozzle body and the adjustment kit.

[0047] Furthermore, a space is formed between the second gripping shell 204 and the screw-on sleeve 203 for the movement of the first gripping shell 101. A slot 114 is formed on the inner circumferential wall of the first gripping shell 101. The slot 114 includes a first limiting surface 115 set along the tangential direction of the first gripping shell 101 and a stop surface 116 set perpendicular to the axial direction of the first gripping shell 101. A buckle 222 is formed on the end of the screw-on sleeve 203 facing the nozzle body. The buckle 222 includes a second limiting surface 223 set along the tangential direction of the screw-on sleeve 203. The buckle 222 is aligned with the slot 114, and the screw-on sleeve 203 is axially plugged into the first gripping shell 101. The buckle 222 contracts radially under pressure, and the stop surface 116 abuts the buckle 222 to indicate that the axial installation is in place, ensuring the precise positioning between the nozzle body and the adjustment kit, making the installation process simpler and more accurate. The first limiting surface 115 abuts against the second limiting surface 223 to indicate the direction of engagement between the external thread 113 and the internal thread 221. The design of the first grip shell 101 and the second grip shell 204 not only provides an aesthetically pleasing appearance for the showerhead, but also enhances the stability of the overall structure and takes into account the user's grip comfort, making the showerhead easier to operate.

[0048] The operation of the nozzle is as follows: When the nozzle body and the adjustment sleeve threads are separated from each other to the maximum distance, the inner spray section 106 and the first inner water outlet 107 are still located in the second water spray section 213, and water flows out through the water outlet 215 to form a rain-like pattern. When the inner spray section 106 and the first inner water outlet 107 further enter the first water spray section 212, the second guide platform 110 does not fully extend out of the straight nozzle 206, and the second guide groove 219 is suitable for guiding the water flow into a straight column water pattern. When the inner spray section 106 further advances, the second guide platform 110 cooperates with the second guide groove 219 to guide the water flow into a straight column water pattern. When the inner spray section 106 further advances, causing the first guide platform 109 to at least partially extend out of the straight nozzle 206, the first guide platform 109 cooperates with the first guide groove 218 to guide the water flow into an umbrella-shaped water pattern. Finally, the inner spray section 106 moves so that the flow stop portion 111 abuts the guide groove to achieve closure, the nozzle body and the adjustment kit thread approach each other to the minimum distance, and the first grip shell 101 and the second grip shell 204 contact axially.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
