DETAILED DESCRIPTION

[0046] ​​Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0047] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the present application. Figure 1 to the drawings Figure 5 and specific embodiments, the present application is described in detail:

[0048] As Figures 1-5 shown, the present application provides a nozzle, which can be used in the technical field of toilets and the like, comprising:

[0049] The water outlet pipe 1 is provided with external threads on the outer wall surface, which is used for threaded connection with the PET braided pipe; and a receiving groove 12 is formed on the pipe wall of the first end 11 of the water outlet pipe 1 along the length direction thereof;

[0050] The connecting pipe 2 is used for connecting with the rubber hose, one end of the connecting pipe 2 is inserted into the receiving groove 12 of the water outlet pipe 1, and the other end of the connecting pipe 2 is formed with a ring-shaped clamping flange 21, the outer diameter of the clamping flange 21 is the same as the outer diameter of the water outlet pipe 1;

[0051] The adjusting assembly 3 is installed between the water outlet pipe 1 and the connecting pipe 2, which is used for controlling the expansion and contraction of the connecting pipe 2 in the receiving groove 12;

[0052] The connecting pipe 2 has an embedded state and an extended state;

[0053] When the connecting pipe 2 is in the embedded state, the clamping flange 21 on the connecting pipe 2 abuts against the end surface of the first end 11 of the water outlet pipe 1, at this time, the threaded connection between the water outlet pipe 1 and the PET braided pipe can be realized through the external threads on the outer wall surface of the water outlet pipe 1, and then the fixed installation of the nozzle is realized;

[0054] When the connecting pipe 2 is in the extended state, the connecting pipe 2 extends out of the first end 11 of the water outlet pipe 1, at this time, the rubber hose can be sleeved and installed on the connecting pipe 2, and then the fixed installation of the nozzle is realized.

[0055] The nozzle of the present application, the connecting pipe 2 of which can be switched between two states, can meet the connection requirements of different types of water inlet pipes, greatly improves the universality of the nozzle, and avoids the situation that multiple nozzles are prepared due to different types of water inlet pipes. This universal design makes the nozzle better adapt to the connection requirements of various water inlet pipes, and users do not need to frequently replace the nozzle, effectively reducing the use cost.

[0056] Meanwhile, the spray head only needs to be manufactured by opening a set of molds, compared with the traditional method of manufacturing different spray head molds for different water inlet pipes, which greatly reduces the mold development cost and significantly saves the production cost.

[0057] In addition, when replacing the water inlet pipe, the staff does not need to disassemble the spray head, but only needs to adjust the adjusting assembly 3 to complete the replacement operation of the water inlet pipe. This design greatly saves the time and labor cost of replacing the water inlet pipe, improves the work efficiency. Moreover, the convenient replacement method does not require the staff to have professional installation and disassembly skills, which reduces the operation difficulty. Compared with the traditional way of disassembling the spray head to replace the water inlet pipe, the design of the spray head of the utility model avoids the risk of damaging the spray head and the installation part, effectively prolongs the service life of the spray head.

[0058] Further, in some specific embodiments, as shown in Figure 1 、 2 The adjusting assembly 3 includes a reset spring member 31, one end of the reset spring member 31 is connected with the bottom wall of the accommodating groove 12 or the side wall close to the bottom wall, and the other end is connected with the connecting pipe 2, realizing the connection between the water outlet pipe 1 and the connecting pipe 2.

[0059] In the use process, the staff can apply pressure to the connecting pipe 2 to press it into the accommodating groove 12. In this process, the reset spring member 31 is compressed, and when the connecting pipe 2 reaches the embedded position, it is switched from the extended state to the embedded state. When the connecting pipe 2 is in the embedded state, the reset spring member 31 is in the compressed state, and if the connecting pipe 2 needs to be adjusted to the extended state, the staff only needs to perform corresponding operation to release the elastic potential energy stored in the reset spring member 31, so as to push the connecting pipe 2 to move outward, so that it extends out of the first end 11 of the water outlet pipe 1.

[0060] The existence of the reset spring member 31 greatly improves the convenience of switching the connecting pipe 2 between the two states. It realizes the state switching of the connecting pipe 2 through a simple spring structure, effectively reducing the manufacturing cost of the spray head. In addition, when the connecting pipe 2 is in the embedded state, the reset spring member 31 can provide a certain pre-tightening force, so that the connection between the connecting pipe 2 and the water outlet pipe 1 is more tight and stable. In the extended state, it can also ensure that the connecting pipe 2 will not easily shake or fall off, thereby improving the overall connection stability of the spray head.

[0061] In some more specific embodiments, as shown in Figure 3 、 4 , 5, a first sliding block 121 and a second sliding block 122 are respectively arranged on the groove wall in the accommodating groove 12.

[0062] Two first sliding grooves 22 and second sliding grooves 23 are formed on the inner wall of the connecting pipe 2, and are respectively opposite to the first sliding block 121 and the second sliding block 122. The first sliding grooves 22 and the second sliding grooves 23 are arranged along the length direction of the connecting pipe 2. The first fixed groove 24 and the second fixed groove 25 are formed on the inner wall of the connecting pipe 2 at both ends of the first sliding grooves 22 and the second sliding grooves 23. The first fixed groove 24 is arranged at the end far away from the water outlet pipe 1, and the second fixed groove 25 is arranged at the end close to the water outlet pipe 1.

[0063] When the connecting pipe 2 needs to be adjusted to the embedded state, the first sliding grooves 22 and the second sliding grooves 23 are respectively slid along the corresponding first sliding block 121 and the second sliding block 122, and the first sliding block 121 and the second sliding block 122 are screwed into the first fixed groove 24, so as to realize the embedded installation of the connecting pipe 2 in the water outlet pipe 1. Specifically, when the connecting pipe 2 is in the embedded state, the worker can use the PET woven pipe to connect the spray head, and the adjustment process is as follows: the worker needs to apply force to the connecting pipe 2 and press it into the accommodating groove 12. In this process, the first sliding grooves 22 and the second sliding grooves 23 on the inner wall of the connecting pipe 2 slide along the first sliding block 121 and the second sliding block 122 on the groove wall of the accommodating groove 12. When the connecting pipe 2 reaches the embedded position, the first sliding block 121 and the second sliding block 122 are rotated into the first fixed groove 24 close to the end of the water outlet pipe 1, so as to realize the embedded installation of the connecting pipe 2.

[0064] When the connecting pipe 2 needs to be adjusted to the embedded state, the first sliding grooves 22 and the second sliding grooves 23 are respectively slid along the corresponding first sliding block 121 and the second sliding block 122, and the first sliding block 121 and the second sliding block 122 are screwed into the first fixed groove 24, so as to realize the embedded installation of the connecting pipe 2 in the water outlet pipe 1. Specifically, when the connecting pipe 2 is in the embedded state, the worker can use the PET woven pipe to connect the spray head, and the adjustment process is as follows: the worker needs to apply force to the connecting pipe 2 and press it into the accommodating groove 12. In this process, the first sliding grooves 22 and the second sliding grooves 23 on the inner wall of the connecting pipe 2 slide along the first sliding block 121 and the second sliding block 122 on the groove wall of the accommodating groove 12. When the connecting pipe 2 reaches the embedded position, the first sliding block 121 and the second sliding block 122 are rotated into the first fixed groove 24 close to the end of the water outlet pipe 1, so as to realize the embedded installation of the connecting pipe 2.

[0065] The combination of the slider, chute, and retaining groove provides stable support and fixation for the connection pipe 2 within the outlet pipe 1. Whether installed in a recessed or extended configuration, this ensures that the connection pipe 2 will not easily wobble or fall off, improving the overall connection stability of the showerhead. Furthermore, when connecting the water inlet pipe, the stable state of the connection pipe 2 ensures a secure and reliable connection between the water inlet pipe and the showerhead, preventing water leakage and loose connections.

[0066] At the same time, the state switching of the connecting pipe 2 is achieved through simple pressing, rotation and spring action, which is very convenient to operate. The staff can easily complete the state adjustment of the connecting pipe 2 and the replacement of the water inlet pipe without using complicated tools or performing tedious operations, which not only improves work efficiency but also reduces the difficulty of operation.

[0067] In this embodiment, the first slider 121 and the second slider 122 are disposed at one end of the receiving groove 10 close to the connecting pipe 2 , and the first slider 121 and the second slider 122 are symmetrically disposed;

[0068] The first chute 22 and the second chute 23 are symmetrically arranged;

[0069] The two first fixing grooves 24 and the two second fixing grooves 25 are symmetrically arranged.

[0070] The symmetrical arrangement of the sliders, chute, and fixed grooves ensures that the forces acting on the connecting tube 2 are more uniform in different states. When the connecting tube 2 is in the embedded or extended state, the first slider 121 and the second slider 122 simultaneously act on the corresponding fixed grooves, preventing the connecting tube 2 from tilting or shaking due to uneven force, thereby improving the stability of the connection. At the same time, the symmetrical slider and chute design can effectively prevent the connecting tube 2 from shifting during the extension and retraction process. When the connecting tube 2 moves, the two sliders slide synchronously in the corresponding chute, ensuring that the connecting tube 2 always moves in the correct direction, thus ensuring the integrity and reliability of the nozzle structure.

[0071] Furthermore, in some specific embodiments, Figure 1 、 2 As shown, the cross-sectional shape of the snap-on edge 21 is a right triangle. Due to the right angle, the snap-on edge 21 can accurately rest against the end face of the outlet pipe 1, ensuring the stability of the connecting pipe 2 in its embedded position and providing accurate positioning for the subsequent threaded connection with the PET braided tube. Furthermore, the right-angled side limits the depth of the connecting pipe 2's insertion into the receiving groove 12, preventing over-insertion of the connecting pipe 2 from damaging the internal structure or affecting the normal function of the nozzle. Furthermore, the outer side of the right triangle is inclined, which facilitates the fitting of the PET braided tube onto the outer wall of the outlet pipe 1.

[0072] Furthermore, in some specific embodiments, Figure 1 、 2 As shown, the spray head further includes a mounting ring 4 and a nozzle assembly 5.

[0073] Among them, the mounting ring 4 is sleeved on the second end 13 of the water outlet pipe 1 and is used to fix the nozzle; in this embodiment, the nozzle is fixed to the toilet by the mounting ring 4, and the mounting ring 4 provides a stable connection point to ensure that the nozzle will not loosen or shift during use.

[0074] The nozzle assembly 5 is installed at the end of the mounting ring 4 away from the connecting pipe 2 and is used for spraying water to achieve a cleaning function.

[0075] Specifically, the nozzle assembly 5 includes a fastening sleeve 51 , a nozzle 52 and a fastening cap 53 .

[0076] The fastening sleeve 51 is fixed to the end of the mounting ring 4 away from the water outlet pipe 1, and the outer wall of the fastening sleeve 51 is provided with external threads. In this embodiment, the inner diameter of the fastening sleeve 51 is larger than the outer diameter of the water outlet pipe 1 and smaller than the outer diameter of the mounting ring 4, providing space for the installation of the nozzle 52.

[0077] The nozzle 52 is arranged in the mounting ring 4 and is fixedly connected to the end of the mounting ring 4 away from the water outlet pipe 1, so that the nozzle 52 can be stably installed in the nozzle and maintain good communication with the water outlet pipe 1.

[0078] The inner wall of the fastening cap 53 is provided with internal threads and is located on the side of the nozzle 52 away from the water outlet pipe 1. The internal threads on the inner wall of the fastening cap 53 are threadedly connected to the external threads on the outer wall of the fastening sleeve 51, thereby locking the nozzle 52. When the fastening cap 53 is tightened, the fastening cap 53 moves toward the nozzle 52, gradually locking the nozzle 52. The threaded connection allows the fastening cap 53 to apply sufficient pressure to firmly fix the nozzle 52 between the mounting ring 4 and the fastening sleeve 51.

[0079] During use, water flows from the outlet pipe 1 into the mounting ring 2 before being ejected through the nozzle 52. Therefore, the design of the nozzle 52 determines the shape, direction, and pressure of the water flow, thereby achieving the cleaning function. Different shapes and structures of the nozzle 52 can produce different water spray effects to meet different cleaning needs. Based on this, the present invention adopts a structural design of the fastening sleeve 51, nozzle 52, and fastening cap 53.

[0080] The threaded connection of the fastening sleeve 51 and the fastening cap 53 makes the installation and disassembly of the nozzle 52 simple and fast. When it is necessary to replace the nozzle 52 or perform maintenance, only the fastening cap 53 needs to be loosened, and the nozzle 52 can be easily taken out for operation. At the same time, by tightening or loosening the fastening cap 53, the tightness of the nozzle 52 can be adjusted, and the angle of the nozzle 52 can be adjusted. This adjustability enables users to flexibly adjust the water spraying direction according to actual needs, improving the applicability and use convenience of the shower head. Different cleaning tasks require different water spraying angles, and the adjustable nozzle 52 can better meet these needs.

[0081] In some more specific embodiments, as shown in Figure 1 、 2 The nozzle assembly 5 further includes a boss 54.

[0082] The boss 54 is arranged in the mounting ring 4 and is fixedly connected to the mounting ring 4 away from the water outlet pipe 1. The boss 54 is semispherical and has a water passage hole 541 formed therein. The water passage hole 541 is in communication with the inside of the water outlet pipe 1. The water passage hole 541 in the boss 54 is in communication with the inside of the water outlet pipe 1, providing a stable passage for water flow. The semispherical design of the boss 54 enables water to flow smoothly from the water outlet pipe into the nozzle 52, reducing water flow resistance and turbulence, and improving water flow stability and uniformity. In this embodiment, the outer diameter of the boss 54 is smaller than the inner diameter of the fastening sleeve 51, and the inner diameter is larger than the inner diameter of the water outlet pipe 1.

[0083] The nozzle 52 is bowl-shaped and has an accommodating cavity 521 formed therein. The accommodating cavity 521 is used to accommodate the boss 54, and the inner wall of the accommodating cavity 521 is fitted on the outer wall of the boss 54. The accommodating cavity 521 of the bowl-shaped nozzle 52 is tightly fitted on the outer wall of the semispherical boss 54, which increases the contact area between the nozzle 52 and the boss 54, improves the sealing and stability of the connection, and effectively prevents water leakage when water flows. Correspondingly, the fastening cap 53 is also umbrella-shaped and is fitted on the outside of the nozzle 52. The fastening cap 53 is fixedly connected to the fastening sleeve 51 by screwing, and the nozzle 52 is firmly fixed between the boss 54 and the fastening cap 53, further enhancing the fixation of the nozzle 52 and ensuring that the nozzle 52 does not loosen or fall off during use, ensuring the normal operation of the shower head.

[0084] In this embodiment, the center of the boss 54 coincides with the center of the water outlet pipe 1 (i.e., the geometric center of the cross section). When the center of the boss 54 coincides with the center of the water outlet pipe 1, the water flow entering the water passage hole 541 of the boss 54 from the water outlet pipe 1 can maintain a relatively uniform flow state, and uniform water flow distribution helps to reduce water flow turbulence and vortex phenomena, improving water flow stability.

[0085] Of course, in order to enhance the connection sealing, a sealing ring 55 can also be provided between the fastening cap 53 and the nozzle 52. Specifically, a sealing groove can be formed on the inner circumferential wall of the fastening sleeve 51 away from the mounting ring 4, and the sealing ring 55 is placed in the sealing groove to achieve a sealed connection and prevent water leakage.

[0086] The utility model discloses a shower head on the basis of above, still provide a kind of closestool, it includes above-mentioned shower head. The closestool includes all the technical solutions of above-mentioned shower head, at least has all the advantages of above-mentioned shower head, here no longer repeat. Setting shower head on closestool, the water flow that shower head sprays is sprayed to the position below the center of the sewage outlet of intelligent closestool, can improve the flushing performance of closestool;Meanwhile, flushing generated noise can also be reduced to a certain extent.

[0087] The above is further described by specific embodiments, but it should be understood that the specific description herein should not be construed as limiting the essence and scope of the utility model, and various modifications made by ordinary skilled persons in the art after reading the specification are within the scope of the utility model.
