[0001] The invention belongs to the technical field of toilets, and in particular relates to a spray head and a toilet with the spray head. Background Art

[0002] As people's living standards continue to improve, smart toilets are becoming more and more popular among consumers. Smart toilets usually have a jet hole at the bottom of the toilet bowl, and a nozzle is installed on the jet hole. The water flow from the nozzle is sprayed at the position below the center of the sewage outlet of the smart toilet, which can more effectively and fully flush the sewage outlet and sewage channel, greatly improving the flushing performance of the smart toilet. At the same time, the design of adding a nozzle can also reduce the noise generated by flushing to a certain extent, and the structure is relatively simple.

[0003] Due to the different water supply sources of toilets, there are generally two ways to connect the nozzles. One is to use a PET braided tube to connect to the nozzle through a thread, and the other is to use a rubber hose that is put on the nozzle and locked with a clamp.

[0004] In this way, it is necessary to make corresponding nozzles according to the different types of water inlet pipes. When the staff needs to replace different types of water inlet pipes, they also need to replace the nozzles at the same time. This process is not only time-consuming and labor-intensive, but also increases the complexity and cost of maintenance. In addition, since it is necessary to make corresponding nozzles according to different types of water inlet pipes, it means that it is necessary to develop and maintain a variety of different nozzle molds, which increases production costs.

[0005] Based on this, the present invention provides a novel nozzle and a toilet with the nozzle to overcome the above-mentioned defects. Summary of the invention

DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0047] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments, the present invention is described in detail:

[0048] like Figure 1-5 As shown, the present invention provides a spray head which can be used in the technical field of toilets, etc., and comprises:

[0049] The water outlet pipe 1 has an outer thread on its outer wall for threaded connection with the PET braided pipe; and a receiving groove 12 is provided on the pipe wall of the first end 11 of the water outlet pipe 1 along its length direction;

[0050] A connecting pipe 2, the connecting pipe 2 is used to connect with a rubber hose, one end of which 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 an annular clamping edge 21, and the outer diameter of the clamping edge 21 is the same as the outer diameter of the water outlet pipe 1;

[0051] An adjusting component 3, the adjusting component 3 is installed between the water outlet pipe 1 and the connecting pipe 2, and is used to control the expansion and contraction of the connecting pipe 2 in the containing groove 12;

[0052] Wherein, 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 edge 21 on the connecting pipe 2 stops 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 tube can be realized through the external thread on the outer wall of the water outlet pipe 1, thereby realizing the fixed installation of the nozzle;

[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 installed on the connecting pipe 2 to achieve fixed installation of the nozzle.

[0055] The nozzle of the present invention has a connection pipe 2 that can switch between two states, thereby being able to meet the connection requirements of different types of water inlet pipes, greatly improving the versatility of the nozzle and avoiding the need to prepare multiple nozzles due to different types of water inlet pipes. This universal design enables the nozzle to better adapt to the connection requirements of various water inlet pipes, and users do not need to frequently replace the nozzle, effectively reducing the cost of use.

[0056] At the same time, the nozzle only needs one set of molds to be produced. Compared with the traditional method of making different nozzle molds for different water inlet pipes, it greatly reduces the mold development cost and significantly saves production costs.

[0057] In addition, when replacing the water inlet pipe, the staff does not need to remove the nozzle, and only needs to adjust the adjustment component 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 and improves work efficiency. Moreover, the convenient replacement method does not require the staff to have professional installation and disassembly skills, which reduces the difficulty of operation. Compared with the traditional method of disassembling the nozzle to replace the water inlet pipe, the design of the nozzle of this invention avoids the risk of damage to the nozzle and the installation part, and effectively extends the service life of the nozzle.

[0058] Furthermore, in some specific embodiments, Figure 1 , 2 As shown, the adjustment assembly 3 includes a return spring member 31, one end of the return spring member 31 is connected to the bottom wall of the accommodating groove 12 or the side wall close to the bottom wall, and the other end is connected to the connecting pipe 2 to achieve the connection between the water outlet pipe 1 and the connecting pipe 2.

[0059] During use, the staff can apply pressure to the connecting pipe 2 to press it into the receiving groove 12. During this process, the return spring member 31 is compressed, and when the connecting pipe 2 reaches the embedded position, it switches from the extended state to the embedded state. When the connecting pipe 2 is in the embedded state, the return spring member 31 is in a compressed state. If the connecting pipe 2 needs to be adjusted to the extended state, the staff only needs to perform corresponding operations to release the elastic potential energy stored in the return spring member 31, so as to push the connecting pipe 2 to move outward and extend it beyond the first end 11 of the outlet pipe 1.

[0060] The presence of the return spring member 31 greatly improves the convenience of switching the connecting pipe 2 between the two states. The state switching of the connecting pipe 2 is achieved through a simple spring structure, which effectively reduces the manufacturing cost of the nozzle. In addition, when the connecting pipe 2 is in the embedded state, the return spring member 31 can provide a certain pre-tightening force, making the connection between the connecting pipe 2 and the water outlet pipe 1 tighter and more stable. In the extended state, it can also ensure that the connecting pipe 2 will not shake or fall off easily, thereby improving the overall connection stability of the nozzle.

[0061] In some more specific embodiments, Figure 3 , 4 As shown in FIG. 5 , a first sliding block 121 and a second sliding block 122 are respectively provided on the inner wall of the receiving groove 12 .

[0062] Two first slide grooves 22 and second slide grooves 23 are respectively provided on the inner wall surface of the connecting pipe 2, which are opposite to the first sliding block 121 and the second sliding block 122. The first slide groove 22 and the second slide groove 23 are arranged along the length direction of the connecting pipe 2, and a first fixed groove 24 and a second fixed groove 25 are formed on the inner wall surface of the connecting pipe 2 at both ends of the first slide groove 21 and the second slide groove 22. The first fixed groove 24 is arranged at an end away from the water outlet pipe 1, and the second fixed groove 25 is arranged at an end close to the water outlet pipe 1.

[0063] When the connecting pipe 2 needs to be adjusted to the embedded state, the first slide groove 22 and the second slide groove 23 are first slid along the corresponding first slider 121 and the second slider 122 respectively, and the first slider 121 and the second slider 122 are screwed into the first fixed groove 24 to realize the embedded installation of the connecting pipe 2 in the outlet pipe 1. Specifically, when the connecting pipe 2 is adjusted to the embedded state, that is, when the staff can use the PET braided tube to connect the nozzle, the adjustment process is as follows: the staff needs to first apply force to the connecting pipe 2 to press it into the receiving groove 12. In this process, the first slide groove 22 and the second slide groove 23 on the inner wall of the connecting pipe 2 slide along the first slider 121 and the second slider 122 on the inner groove wall of the receiving groove 12 respectively. When the connecting pipe 2 reaches the embedded position, by rotating the connecting pipe 2, the first slider 121 and the second slider 122 are respectively screwed into the first fixed groove 24 near one end of the outlet pipe 1, thereby realizing the embedded installation of the connecting pipe 2.

[0064] When the connecting pipe 2 needs to be adjusted to the extended state, the first slide groove 22 and the second slide groove 23 are first slid along the corresponding first slider 121 and the second slider 122 respectively, and the first slider 121 and the second slider 122 are screwed into the second fixed groove 25 to realize the extended installation of the connecting pipe 2 in the outlet pipe 1. Specifically, when the connecting pipe 2 is adjusted to the extended state, that is, when the staff can use the rubber hose to connect the nozzle, the adjustment process is as follows: the staff first rotates the connecting pipe 2 to make the first slider 121 and the second slider 122 slide out of the first fixed groove 24 and enter the first slide groove 24 and the second slide groove 25. At this time, the elastic potential energy stored in the reset spring member 31 is released, pushing the connecting pipe 2 to move outward. In the process of extending the connecting pipe 2, the first slide groove 24 and the second slide groove 25 slide along the first slider 121 and the second slider 122. When the connecting pipe 2 is extended to a certain position, the connecting pipe 2 is rotated again so that the first slider 121 and the second slider 122 are respectively screwed into the second fixing groove 25 away from one end of the water outlet pipe 1, thereby realizing the extended installation of the connecting pipe 2.

[0065] The cooperation between the slider, the slide groove and the fixing groove provides stable support and fixation for the installation of the connecting pipe 2 in the water outlet pipe 1. Whether it is embedded installation or extended installation, it can ensure that the connecting pipe 2 will not shake or fall off easily, thereby improving the overall connection stability of the nozzle. When connecting the water inlet pipe, the stable state of the connecting pipe 2 can ensure that the connection between the water inlet pipe and the nozzle is firm and reliable, avoiding the problems of water leakage and loose connection.

[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 slide groove 22 and the second slide groove 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 slider, the slide groove and the fixed groove makes the force on the connecting tube 2 more uniform in different states. When the connecting tube 2 is in the embedded state or the extended state, the first slider 121 and the second slider 122 act on the corresponding fixed groove at the same time, avoiding 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 slide groove 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 slide groove to ensure that the connecting tube 2 always moves in the correct direction, 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 clamping edge 21 is a right triangle. Due to the existence of the right angle, the clamping edge 21 of the right triangle can accurately stop on the end face of the water outlet pipe 1, ensuring the stability of the connecting pipe 2 in the embedded position, and providing accurate positioning for the subsequent threaded connection with the PET braided tube. And the right-angled side can limit the depth of the connecting pipe 2 inserted into the receiving groove 12, avoiding excessive insertion of the connecting pipe 2 and damaging the internal structure or affecting the normal function of the nozzle. In addition, the outer side of the right triangle is set as an inclined surface, which is conducive to the PET braided tube being mounted on the outer wall of the water outlet pipe 1.

[0072] Furthermore, in some specific embodiments, Figure 1 , 2 As shown, the spray head also 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. 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 an external thread is provided on the outer wall of the fastening sleeve 51. 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 disposed in the mounting ring 4 and fixedly connected to an end of the mounting ring 4 away from the water outlet pipe 1 , so that the nozzle 52 can be stably mounted 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 an internal thread and is arranged on the side of the nozzle 52 away from the water outlet pipe 1. The internal thread on the inner wall of the fastening cap 53 is threadedly connected with the external thread on the outer wall of the fastening sleeve 51 to lock the nozzle 52. When the fastening cap 53 is tightened, the fastening cap 53 moves toward the direction of the nozzle 52 and gradually locks the nozzle 52. With the threaded connection, the fastening cap 53 can 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 water outlet pipe 1 into the mounting ring 2 and then sprays out 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. Nozzles 52 of different shapes and structures can produce different water spraying effects and meet different cleaning needs. Based on this, the present invention adopts the structural design of the fastening sleeve 51, the nozzle 52, and the fastening cap 53.

[0080] The threaded connection between the fastening sleeve 51 and the fastening cap 53 makes the installation and removal of the nozzle 52 simple and quick. When the nozzle 52 needs to be replaced or repaired, the nozzle 52 can be easily taken out for operation by simply loosening the fastening cap 53. At the same time, by tightening or loosening the fastening cap 53, the tightness of the nozzle 52 can be adjusted, thereby adjusting the angle of the nozzle 52. This adjustability enables the user to flexibly adjust the water spray direction according to actual needs, thereby improving the applicability and ease of use of the nozzle. Different cleaning tasks require different water spray angles, and the adjustable nozzle 52 can better meet these needs.

[0081] In some more specific embodiments, Figure 1 , 2 As shown, the nozzle assembly 5 further includes a boss member 54 .

[0082] The boss member 54 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; the boss member 54 is hemispherical, and a water hole 541 is provided inside the boss member 54, and the water hole 541 is connected to the inside of the water outlet pipe 1. The water hole 541 inside the boss member 54 is connected to the inside of the water outlet pipe 1, providing a stable channel for the water flow. The hemispherical boss member 54 design enables the water flow to flow smoothly from the water outlet pipe into the nozzle 52, reducing the resistance and turbulence of the water flow, and improving the stability and uniformity of the water flow. In this embodiment, the outer diameter of the boss member 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 is provided with a receiving chamber 521 inside. The receiving chamber 521 is used to receive the boss 54. The inner wall of the receiving chamber 521 is fitted on the outer wall of the boss 54. The receiving chamber 521 of the bowl-shaped nozzle 52 is tightly fitted with the outer wall of the hemispherical boss 54. This design increases the contact area between the nozzle 52 and the boss 54, and improves the sealing and stability of the connection. When water flows through, it can effectively prevent water leakage. Correspondingly, the fastening cap 53 is also umbrella-shaped. The umbrella-shaped fastening cap 53 is snap-fitted and installed on the outside of the nozzle 52. Through the threaded connection with the fastening sleeve 51, the nozzle 52 is firmly fixed between the boss 54 and the fastening cap 53, which further strengthens the fixation of the nozzle 52, ensures that the nozzle 52 will not loosen or fall off during use, and ensures the normal operation of the nozzle.

[0084] In this embodiment, the center of the sphere of the boss 54 coincides with the center of the circle of the water outlet pipe 1 (i.e., the geometric center of the cross section). When the center of the sphere of the boss 54 coincides with the center of the circle of the water outlet pipe 1, the water flow can maintain a relatively uniform flow state during the process of entering the water through hole 541 of the boss 54 from the water outlet pipe 1, and the uniform water flow distribution helps to reduce the turbulence and eddy current phenomenon of the water flow and improve the stability of the water flow.

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

[0086] Based on the above-mentioned nozzle, the present invention further provides a toilet, which includes the above-mentioned nozzle. The toilet includes all the technical solutions of the above-mentioned nozzle, and at least has all the advantages of the above-mentioned nozzle, which will not be repeated here. The nozzle is arranged on the toilet, and the water flow sprayed by the nozzle is sprayed at a position below the center of the sewage outlet of the smart toilet, which can improve the flushing performance of the toilet; at the same time, it can also reduce the noise generated by flushing to a certain extent.

[0087] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
