[0033] The utility model provides a spray head for a toilet.

[0034] In the embodiment of the present utility model, please refer to Figures 4 to 6 The toilet nozzle 10 includes a nozzle body 100, the nozzle body 100 has an outlet end 141, a water flow channel is arranged in the nozzle body 100, the water flow channel includes a water inlet section 150 and a water outlet section 160 connected to the water inlet section 150, the water flow cross section of the water outlet section 160 is larger than the water flow cross section of the water inlet section 150, and the water flow cross section of the water outlet section 160 is gradually expanded toward the outlet end 141.

[0035] Specifically, the toilet nozzle is used for a toilet and can be installed in the toilet bowl 11 of the toilet. For example, the toilet nozzle is installed in the toilet and exposed to the inner wall of the toilet bowl 11 through a through hole; please refer to Figures 2 to 3 , or it is installed on the inner wall of the toilet bowl 11 of the toilet, the end surface of the toilet nozzle can be flush with the inner wall of the toilet bowl 11, or the end surface of the toilet nozzle protrudes from the inner wall of the toilet bowl 11.

[0036] Please refer to Figures 4 to 6 The nozzle body 100 can be arranged in a block shape, a strip shape, or a ring shape. The nozzle body 100 has an outlet end 141. A water flow channel is arranged in the nozzle body 100. The water flow channel extends toward the outlet end 141, so that the noise reduction medium can flow out from the outlet end 141 through the water flow channel. Specifically, the water flow channel includes an inlet section 150 and an outlet section 160. The inlet section 150 is connected to the outlet section 160. The noise reduction medium enters the inlet section 150 and flows out from the outlet section 160.

[0037] Please refer to Figure 6The water flow cross section of the water inlet section 150 may remain unchanged in the extension direction of the water inlet section 150, and the water flow cross section of the water outlet section 160 is larger than the water flow cross section of the water inlet section 150. Thus, the water flow cross section through the water outlet section 160 increases, and the water outlet section 160 reduces the pressure and speeds up the noise reduction medium flowing through, thereby reducing the flow rate and pressure of the noise reduction medium discharged from the water outlet section 160.

[0038] It is understandable that the noise reduction medium can be a fluid medium or a gas medium. When the noise reduction medium is a fluid medium, the fluid medium can be water. The noise reduction medium can be normal pressure water, and the normal pressure water is depressurized and decelerated by the water outlet section 160, or the noise reduction medium can be low pressure and low speed water, and the low pressure and low speed water is decelerated and depressurized by the water outlet section 160.

[0039] Please refer to Figure 6 The water flow cross section of the water outlet section 160 of the nozzle body 100 is gradually expanded in the direction toward the outlet end 141, thereby gradually slowing down and reducing the pressure of the passing water flow, gradually reducing the speed of the noise reduction medium, thereby avoiding abnormal noise in the nozzle body 100 and further reducing noise.

[0040] Please refer to Figure 1 to Figure 2 The toilet bowl 11 is provided with a bottom flushing nozzle 720, which is used to spray high-pressure and high-speed flushing water, so as to induce a siphon effect in the toilet bowl 11 to take away the dirt in the toilet bowl 11. The toilet nozzle 10 can be installed above the bottom flushing nozzle 720, and the noise reduction medium discharged by the toilet nozzle 10 covers the high-speed flushing water sprayed by the bottom flushing nozzle 720, or forms a water curtain on the lateral surface of the toilet bowl 11, such as draining water from the side wall of the toilet bowl 11 to the inner cavity of the toilet bowl, thereby blocking the transmission of the noise generated by the impact of the high-speed flushing water in the sound transmission medium air, thereby reducing the noise.

[0041] Therefore, not only the impact noise generated by the water spraying from the bottom flushing nozzle 720 is reduced, but also the noise caused by the high-speed impact of the flushing water on the bottom of the toilet bowl due to the cavity effect is reduced, and the dirt stirred up by flushing and diffused in the air is reduced, thereby reducing pollution; or the noise reduction medium discharged by the toilet nozzle 10 is used to buffer the flushing water sprayed from the bottom flushing nozzle 720, reduce the flow rate of the high-speed flushing water, thereby reducing the noise generated by the impact of the flushing water, and achieving a noise reduction effect.

[0042] Please refer to Figure 4 and Figure 6 The nozzle body 100 also has an inlet end 142. The axis of the water inlet section 150 and the axis of the water outlet section 160 can coincide with each other, and the inlet end 142 and the outlet end 141 are arranged opposite to each other. Figure 6In one embodiment, the axis of the water inlet section 150 intersects with the axis of the water outlet section 160. By intersecting the axis of the water inlet section 150 with the axis of the water outlet section 160, that is, the inlet end 142 and the outlet end 141 are not at opposite ends of the nozzle body 100, the length of the water flow channel can be shortened and the speed of the noise reduction medium in the water flow channel can be further reduced.

[0043] For further information, please refer to Figure 6 In one embodiment, the axis of the water inlet section 150 is perpendicular to the axis of the water outlet section 160, that is, the outlet end 141 is located on one side of the nozzle body 100. Please continue to refer to Figures 4 to 6 The outlet end 141 can be located at the end of the water inlet section 150 away from the inlet end 142, or it can be located between the inlet end 142 and the end of the water inlet section 150. That is to say, the outlet end 141 and the inlet end 142 can be located on the adjacent two sides of the nozzle body 100, or they can be located on the opposite sides of the nozzle body 100.

[0044] The nozzle body 100 has a noise reduction port 141a, i.e., a water outlet, which is connected to the water outlet section 160. The noise reduction port 141a has various shapes, such as a circular port or an elliptical port. Figures 4 to 6 The noise reduction port 141a can be set as a rectangular port, and the diameter of the noise reduction port 141a extends along the axis of the water inlet section 150, thereby increasing the diameter of the noise reduction port 141a in the horizontal direction, which is conducive to forming a water curtain in the horizontal direction.

[0045] Please refer to Figure 4 and Figure 6 In one embodiment, the nozzle body 100 has a noise reduction port 141a connected to the water outlet section 160, and the noise reduction port 141a is arranged in a ring shape. When the nozzle body 100 is arranged in a ring shape, the noise reduction port 141a is opened on the inner side of the nozzle body 100, and the noise reduction port 141a extends along the circumference of the nozzle body 100 to form a ring-shaped port. The nozzle 10 for toilet can be arranged in a ring at the bottom of the toilet bowl 11, and the ring-shaped noise reduction port 141a is exposed in the toilet bowl 11, and the noise reduction medium is discharged from the noise reduction port 141a, so that a water curtain can be formed above the bottom flush nozzle 720.

[0046] Please refer to Figure 4 and Figure 6In one embodiment, the toilet nozzle 10 includes an interface portion 170, and the interface portion 170 is protruding from the nozzle body 100, and the water inlet section 150 passes through the interface portion 170. The water inlet section 150 passes through the interface portion 170, so that the water inlet section 150 is connected with the interface portion 170. The interface portion 170 is located on one side of the nozzle body 100, and the interface portion 170 may form an inlet end 142, and the inlet portion and the nozzle body 100 are integrally formed. The outer diameter of the interface portion 170 may be smaller than the nozzle body 100, and it may be connected to a pipeline through the interface portion 170, so as to provide a noise reduction medium to the water inlet section 150. Please refer to Figure 4 , the interface portion 170 can be set in a cylindrical shape.

[0047] Please continue to refer to Figure 4 and Figure 6 In one embodiment, the toilet nozzle 10 includes an outlet portion 180, the outlet portion 180 is convexly arranged on one side of the nozzle body 100, and the water outlet section 160 passes through the outlet portion 180. The water outlet section 160 passes through the outlet portion 180, and a noise reduction port 141a can be formed in the outlet portion 180. By providing the outlet portion 180, the flow path of the noise reduction medium in the nozzle body 100 is extended, and the noise reduction of the noise reduction medium is further stabilized.

[0048] Understandably, please continue to refer to Figure 6 The water flow cross section of the outlet 180 is reduced and expanded in the direction away from the water outlet section 160, further decelerating and reducing the pressure of the noise reduction medium. The outlet 180 can be extended along the periphery of the noise reduction port 141a so that the outlet 180 is connected with the water outlet section 160 to discharge the noise reduction medium.

[0049] The toilet nozzle 10 can be screwed to the toilet bowl or glued to the toilet bowl. Figure 4 The interface portion 170 can be connected to a water pipe to transport the noise reduction medium to the water inlet section 150; an adhesive layer can be provided on the end surface of the outlet end 141, or an adhesive layer can be provided on the inlet end 142 to adhere the toilet nozzle 10 to the toilet bowl to fix the toilet nozzle 10.

[0050] Please refer to Figure 1 to Figure 2The utility model also provides a toilet, which includes a toilet body 1, a bottom flushing nozzle 720 and a toilet nozzle 10. The toilet body 1 is provided with a toilet bowl 11. The bottom flushing nozzle 720 is provided in the toilet bowl 11 to provide flushing water to the toilet bowl 11, so as to induce a siphon effect in the toilet bowl 11. The toilet nozzle 10 is exposed on the inner wall of the toilet bowl 11, and is higher than the bottom flushing nozzle 720 relative to the bottom of the toilet body 1. The specific structure of the toilet nozzle 10 refers to the above embodiment. Since the toilet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0051] Please refer to Figures 2 to 3 , the toilet nozzle 10 is higher than the bottom flush nozzle 720, so that the noise reduction medium discharged from the toilet nozzle 10 can be higher than the flushing water sprayed from the bottom flush nozzle 720. The noise reduction medium discharged from the toilet nozzle 10 can be flushed to the inner wall of the toilet bowl 11 on the opposite side, forming a water curtain in the lateral direction of the toilet bowl 11, separating the environment below and above the water curtain, and achieving a noise reduction effect; and the noise reduction medium can brush the wall of the toilet bowl 11 sprayed with flushing water, reducing the noise caused by the high-speed impact of the flushing water from the bottom flush nozzle 720 on the wall of the toilet bowl 11 to form a cavity effect. Or, directly under the action of gravity, the noise reduction medium brushes the wall of the toilet bowl 11 sprayed with flushing water, reducing the noise caused by the high-speed impact of the flushing water on the wall of the toilet bowl 11 to form a cavity effect.

[0052] Please refer to Figures 2 to 3 The bottom flushing nozzle 720 is used to spray high-pressure and high-speed flushing water to induce a siphon effect, so that the flushing water carries away the dirt. Figures 7 and 8 The bottom flushing nozzle 720 may be provided with a bottom flushing channel, which extends from the water inlet end 100a to the water outlet end 100b, so that water enters the water inlet end 100a, enters the bottom flushing channel, and then exits from the water outlet end 100b. It can be understood that the bottom flushing nozzle 720 is used to provide fast and high-pressure flushing water, so that a siphon effect can be formed in the toilet bowl 11.

[0053] The water inlet end 100a and the water outlet end 100b can be arranged opposite to each other. Figure 8 In one embodiment, a flange 192 is formed at the water outlet 100b, and the flange 192 can cover the periphery of the hole of the toilet bowl 11; an external thread 191 can be formed from the middle of the nozzle body 100 to the water outlet 100b, and the toilet bowl 11 can be provided with a corresponding internal thread. Please refer to Figure 7 The water outlet end 100b of the bottom flush nozzle 720 is provided with a water spray hole 720a, and the water spray hole 720a can be set in a crescent shape.

[0054] During the flushing operation, the bottom flushing nozzle 720 may discharge water and the toilet nozzle 10 may discharge the noise reduction medium at the same time, or separately; or one may discharge water first and then the other, or both may discharge water at the same time. Figure 1 In one embodiment, the toilet further includes a fourth water tank and a fourth water outlet pipe 440 connected to the fourth water tank, and the fourth water outlet pipe 440 is connected to the toilet nozzle 10 to communicate with the water inlet section 150.

[0055] Please refer to Figure 1 and Fig. 9 One end of the fourth water outlet pipe 440 is connected to the fourth water tank, and the other end is connected to the toilet nozzle 10, so as to provide noise reduction medium to the water inlet section 150, and then the type of noise reduction medium can be changed, or the noise reduction medium can be provided before the flushing water, so that the noise reduction medium flows out earlier than the flushing water to form a water curtain in advance or brush the wall of the toilet bowl 11. It can be understood that the fourth water tank can also provide flushing water to the bottom flushing nozzle 720.

[0056] Please refer to Figure 1 and Fig. 9 In one embodiment, the toilet further includes a flushing valve 620, a flushing nozzle 710, a fifth water outlet pipe and a sixth water outlet pipe 460, wherein the flushing nozzle 710 is installed on the toilet bowl 11 and connected to the fifth water outlet pipe; the bottom flushing nozzle 720 is connected to the sixth water outlet pipe 460, and the fifth water outlet pipe and the sixth water outlet pipe 460 are respectively connected to the flushing valve 620 to control the flow of water in the fifth water outlet pipe and the sixth water outlet pipe 460.

[0057] It is understandable that the flushing valve 620 can refer to the control valve 610 described above, and the flushing nozzle 710 can be installed at the top of the toilet body 1 near the opening of the toilet bowl, so that the water discharged by the flushing nozzle 710 can flush the dirt on the inner wall of the toilet bowl 11. The flushing valve 620 can control the flow of water in the fifth water outlet pipeline and the sixth water outlet pipeline 460. For example, a part of the water can be first sent to the flushing nozzle 710 through the fifth water outlet pipeline for flushing, and then another part of the water can be sent to the bottom flushing nozzle 720 through the sixth water outlet pipeline 460 to cause a siphon effect.

[0058] The flush valve 620 can be connected to the fourth water tank, see Figure 1 to Figure 2 , Fig. 9In one embodiment, the toilet further includes a second water inlet pipe 820, one end of which is connected to the flushing valve 620, and the other end is used to connect to a water pipe. Alternatively, the toilet further includes a third water tank, the other end of which is connected to the third water tank, and the third water tank stores flushing water. In other words, the second water inlet pipe 820 can draw water from the third water tank or directly from a water pipe.

[0059] Please refer to Figure 2 In one embodiment, there are at least two toilet nozzles 10, and the two toilet nozzles 10 are arranged opposite to each other; or, there are multiple toilet nozzles 10, and the multiple toilet nozzles 10 are arranged at intervals around the toilet bowl 11.

[0060] When the number of the toilet nozzles 10 is two, the two toilet nozzles 10 are arranged on the toilet body 1, facing the toilet bowl 11, and are arranged opposite to each other, so that the two toilet nozzles 10 can be arranged opposite to each other, forming a water curtain in the lateral direction of the toilet bowl 11. When the number of the toilet nozzles 10 is greater than two, multiple toilet nozzles 10 are arranged on the toilet body 1 and arranged in a circle, and the spray direction of each toilet nozzle 10 is toward the inner cavity of the toilet bowl 11, and they are arranged opposite to each other, so that a water curtain can be formed in the toilet bowl 11.

[0061] The bottom flush nozzle 720 and the toilet bowl 11 can be detachable or inseparable. Figures 2 to 3 In one embodiment, the bottom flushing nozzle 720 is integrally provided with the toilet bowl 11 or can be detached. When the bottom flushing nozzle 720 is integrally provided with the toilet bowl 11, the bottom flushing nozzle 720 and the toilet bowl 11 can be integrally injection molded or cast; when the bottom flushing nozzle 720 and the toilet bowl 11 are detachably provided, the bottom flushing nozzle 720 and the toilet bowl 11 can be screwed together by threads.
