[0048] Existing showerhead toilets generally suffer from inconvenience and insecurity in showerhead installation. On one hand, some products were not designed with user convenience in mind, resulting in numerous installation steps, difficult operation, and even the need for special tools, causing inconvenience to users. On the other hand, ensuring the showerhead's stability after installation is also a significant challenge. Because the showerhead needs to frequently switch functions during use, an insecure installation can easily lead to loosening or even detachment, affecting the user experience.

[0049] To address the aforementioned technical problems, this embodiment provides a spray-type toilet. (See reference...) Figures 1 to 5 As shown, Figure 1 This is a perspective view of the toilet in an embodiment of this application. Figure 2 This is a cross-sectional view of the toilet in an embodiment of this application. Figure 3 yes Figure 2A schematic diagram of the area indicated by the dashed line. Figure 4 This is an exploded view of the nozzle device in the embodiments of this application. Figure 5 This is a perspective view of the nozzle device in the embodiments of this application.

[0050] A spray-type toilet according to this embodiment includes: toilet body 1 and spray head device 2.

[0051] The toilet body 1 has an inner wall 11 and an installation cavity 12 on the outer side of the inner wall 11, so that the operator can install the spray head device 2 into the toilet body 1 through the installation cavity 12; the installation cavity 12 communicates with the outside of the toilet body, and the inner wall 11 has an installation hole 13 communicating with the installation cavity 12; the installation hole 13 is used to install the spray head device 2.

[0052] The nozzle device 2 includes a main body 21, a first nut 22, a second nut 23, and an anti-slip pad 24. The main body 21 is provided with a nozzle assembly 3, and a first threaded portion 211 and a second threaded portion 212 are sequentially provided on its outer side along a straight line. A limit wall 213 is provided between the first threaded portion 211 and the second threaded portion 212. The first threaded portion 211 and the second threaded portion 212 are provided with external threads.

[0053] Among them, see Figure 3 As shown, the main body 21 is partially disposed within the mounting hole 13. The first threaded portion 211 is exposed on the inner side of the inner wall 11, and the second threaded portion 212 is disposed in the mounting cavity 12. The first nut 22 is screwed onto the first threaded portion 211. The limiting wall 213 abuts against the outer side of the inner wall 11 to lock the main body 21 onto the inner wall 11. The second nut 23 is screwed onto the second threaded portion 212 and abuts against the cavity wall of the mounting cavity 12 at the end opposite to the first threaded portion 211. The second nut 23 can be a fine-tuning nut to perform fine-tuning and fastening.

[0054] In some implementations, see Figure 3 and Figure 4As shown, the nozzle device 2 also includes elastic pads 25. At least two elastic pads 25 are provided, respectively positioned between the first nut 22 and the inner side of the inner wall 11, and between the limiting wall 213 and the outer side of the inner wall 11. During installation, the elastic pad 25 is first accurately placed at the pre-set corresponding position between the first nut 22 and the inner side of the inner wall 11; the other elastic pad 25 is placed between the limiting wall 213 and the outer side of the inner wall 11, also accurately positioned accordingly. The elastic pads 25 effectively buffer the pressure and vibration between the first nut 22 and the inner side of the inner wall 11, and between the limiting wall 213 and the outer side of the inner wall 11. During toilet use, the nozzle device 2 may shift or loosen due to water flow impact, mechanical vibration, etc. The elastic pads 25 can absorb this energy, reduce wear between components, improve the stability and reliability of the nozzle device 2, extend its service life, and also improve the sealing of the nozzle device 2 to prevent liquid leakage.

[0055] See Figure 3 and Figure 4 As shown, in some embodiments, the nozzle device 2 further includes a flat washer 26, which is disposed between the elastic pad 25 and the first nut 22. During installation, the elastic pad 25 is first placed in the appropriate position, and then the flat washer 26 is placed flat on the elastic pad 25. For example, the elastic pad 25 and the flat washer 26 are provided with fitting holes and are fitted onto the first threaded portion 211. Finally, the first nut 22 is tightened, so that the flat washer 26 and the elastic pad 25 are tightly fitted together. The flat washer 26 can increase the contact area between the first nut 22 and the elastic pad 25, making the force applied by the first nut 22 more evenly distributed on the elastic pad 25, avoiding excessive local pressure that could damage the elastic pad 25. At the same time, the flat washer 26 can also provide some protection, preventing the first nut 22 from scratching or wearing the elastic pad 25 during tightening, further improving the stability and reliability of the nozzle device 2, and also serving as assembly compensation for unevenness of the ceramic wall.

[0056] See Figure 3 and Figure 4 As shown, in some embodiments, the nozzle assembly 2 further includes an anti-slip pad 24, which is disposed at the end of the second nut 23, and the second nut 23 abuts against the cavity wall of the mounting cavity 12 via the anti-slip pad 24. The anti-slip pad 24 increases the friction between the second nut 23 and the cavity wall of the mounting cavity 12, preventing the second nut 23 from loosening due to vibration or external force during use. This helps maintain the installation stability of the nozzle assembly 2, ensuring that the nozzle can work normally and improving the performance and safety of the toilet.

[0057] See Figure 5As shown, in some embodiments, the main body 21 has a stop surface 216 at one end of the second threaded portion 212 near the limiting wall 213. The stop surface 216 is configured to prevent the second nut 23 from moving towards the limiting wall 213. A reinforcing rib 217 is provided between the stop surface 216 and the limiting wall 213. The stop surface 216 limits the range of movement of the second nut 23, preventing the second nut 23 from being over-tightened and damaging other components, and ensuring the installation accuracy and stability of the nozzle device 2. The reinforcing rib 217 enhances the structural strength between the stop surface 216 and the limiting wall 213, improves the overall rigidity and stability of the main body 21, reduces deformation or damage caused by external forces, and extends the service life of the toilet.

[0058] See Figures 6 to 10 As shown, Figure 6 This is an exploded view of the nozzle assembly in an embodiment of this application. Figure 7 This is a perspective view of the nozzle assembly in the embodiment of this application when the nozzle is extended. Figure 8 This is a cross-sectional view of the nozzle assembly in an embodiment of this application when the nozzle is extended. Figure 9 This is a perspective view of the nozzle assembly in the embodiment of this application when the nozzle is retracted. Figure 10 This is a cross-sectional view of the nozzle assembly in an embodiment of this application when the nozzle is retracted. In some embodiments, the nozzle assembly 3 includes an outer sleeve 31, a nozzle 32, a return spring 33, and an end cap 34; the main body 21 is provided with an inner cavity 214, and the outer sleeve 31 is fixedly disposed inside the main body 21 by the first nut 22; a clearance hole 221 is provided in the middle of the nut, and the nozzle 32 is provided with a nozzle 321 and is movably disposed inside the outer sleeve 31 so that the nozzle 321 extends out from the clearance hole 221 or retracts into the outer sleeve 31; the return spring 33 is disposed between the nozzle 32 and the outer sleeve 31 so that the nozzle 32 is initially hidden inside the outer sleeve 31; the inner side of the outer sleeve 31 is provided with A first limiting surface 311 is provided, and a second limiting surface 322 is provided on the outer side of the nozzle 32. The first limiting surface 311 contacts the second limiting surface 322 when the nozzle 321 extends, so as to limit the maximum extension distance of the nozzle 32. The end cap 34 is detachably connected to the end of the outer sleeve 31 away from the first nut 22 to prevent the nozzle 32 from detaching from the outer sleeve 31. The main body 21 is provided with a water inlet pipe 215 communicating with the inner cavity 214. The end of the outer sleeve 31 away from the first nut 22 or the end cap 34 is provided with a water inlet 35 communicating with the inner cavity 214. The water inlet 35 communicates with the nozzle 32 through the internal space of the outer sleeve 31.

[0059] The nozzle assembly 3 described above firstly enables water spraying. Water is introduced into the inner cavity 214 of the main body 21 through the inlet pipe 215, then enters the outer sleeve 31 through the inlet 35, and finally sprays out from the nozzle 321, meeting the cleaning needs of the toilet. Secondly, it has a reset function: the reset spring 33 allows the nozzle 32 to be initially hidden inside the outer sleeve 31. After spraying, the nozzle 32 automatically resets under the action of the reset spring 33, improving ease of use. Simultaneously, it has a limiting function: the first limiting surface 311 and the second limiting surface 322 limit the maximum extension distance of the nozzle 32, preventing excessive extension and damage to other components, ensuring the normal operation of the nozzle assembly 3. Finally, and equally importantly, the nozzle assembly 3 is detachable: the detachable connection between the end cap 34 and the outer sleeve 31 facilitates maintenance and replacement of the nozzle 32 and the reset spring 33, reducing maintenance costs.

[0060] For example, the end cap 34 and the outer sleeve 31 are fixed together by a snap-fit ​​connection or a threaded engagement.

[0061] In some implementations, see Figure 6 and Figure 7 As shown, the nozzle assembly 2 also includes an ejector spring 27, which is located between the end cap 34 and the main body 21, and provides a spring force to the nozzle assembly 3 in the direction of the first nut 22. When the nozzle assembly 32 is removed for replacement or cleaning, the ejector spring 27 can easily eject the nozzle assembly 32 from the main body 21 by loosening the first nut 22, thus improving the disassembly efficiency of the nozzle assembly 3.

[0062] The toilet body 1 of this application has an installation cavity 12 on the outer side of the inner wall 11, which communicates with the outside of the toilet body. The inner wall 11 also has an installation hole 13 communicating with the installation cavity 12. Installing the spray nozzle device 2 is simple and efficient. Simply pass the body 21 of the spray nozzle device 2 through the installation hole 13. The first threaded portion 211 of the body 21 is naturally exposed on the inner side of the inner wall 11, while the second threaded portion 212 is located inside the installation cavity 12. Then, through a simple screwing action, the first nut 22 is tightly engaged with the first threaded portion 211, while the limiting wall 213 firmly abuts against the outer side of the inner wall 11. In this way, the body 21 is firmly fixed to the inner wall 11. Subsequently, the second nut 23 is screwed on, so that the side opposite to the first threaded portion 211 tightly abuts against the cavity wall of the installation cavity 12, providing reliable auxiliary fixing. The significant advantages of the above structure are as follows: Firstly, it offers ease of installation: Since the mounting cavity 12 is connected to the outside of the toilet body, installers do not need to enter the narrow space inside the toilet for complex operations. They can easily complete a series of actions, such as passing the main body 21 through the mounting hole 13 and tightening the nut, simply by using the mounting cavity 12 from the outside. This greatly reduces the difficulty of installation, improves installation efficiency, and saves time and labor costs. Secondly, it provides secure installation: The initial fixation of the main body 21 to the inside of the inner wall 11 is achieved through the screwing of the first nut 22 to the first threaded part 211 and the abutment of the limiting wall 213 to the outer side of the inner wall 11. The screwing of the second nut 23 to the second threaded part 212 and its abutment to the cavity wall of the mounting cavity 12 further enhance the reliability of the fixation. This dual fixing method allows the nozzle device 2 to be stably installed on the toilet. Even under the impact of water flow, vibration, and other external forces during long-term use, it is not easy to loosen or fall off, ensuring the normal use and functional stability of the toilet.
