[0053] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0054] like Figure 1-6 Combination Figure 9-10As shown, an embodiment of the present invention provides a nozzle assembly including a pipe body 1 and a flushing device 2 detachably mounted on the front end of the pipe body 1.

[0055] The pipe body 1 has an installation channel 11 for installing water pipes.

[0056] The flushing device 2 includes a device body 21 with a mounting cavity 211, a flushing nozzle 22 for flushing the human body, and a flushing spray head 23 for flushing the toilet seat cavity 71.

[0057] The flushing nozzle 22 is at least partially installed in the mounting cavity 211, with the nozzle orifice 223 facing upwards. The flushing head 23 is connected to the device body 21, with the nozzle 231 facing downwards.

[0058] An independent nozzle water supply channel 224 and a nozzle water supply channel 225 are formed between the flushing nozzle 22 and the cavity wall of the mounting cavity 211. The inlets of the nozzle water supply channel 224 and the nozzle water supply channel 225 are both located in the mounting channel 11.

[0059] The nozzle assembly provided by this invention is mainly used in toilets. The nozzle assembly includes a pipe body 1 and a flushing device 2. The pipe body 1 has an installation channel 11, and the upper part of the front end of the pipe body 1 has an installation hole 12.

[0060] The flushing device 2 integrates a flushing nozzle 22 and a flushing spray head 23. The flushing nozzle 22 is used to flush the private parts of the human body, and the flushing spray head 23 is used to flush the toilet body 7 (ceramic body).

[0061] Specifically, the rinsing device 2 includes a device body 21, a rinsing nozzle 22, and a rinsing spray head 23.

[0062] The main body 21 of the device has a mounting cavity 211 with an opening at the top. A flushing nozzle 22 is installed in the mounting cavity 211. A flushing head 23 is connected to the main body 21 and is located outside and in front of the mounting cavity 211. The head 231 is below the pipe body 1 and faces downward. After the pipe body 1 is driven to extend, the head 231 sprays water downward to flush the wall of the toilet chamber 71 of the toilet body 7, providing a wide flushing range.

[0063] Preferably, the nozzle 231 is located in the middle of the toilet cavity 71 along the width direction of the toilet body 7.

[0064] Depending on the needs, spray holes in different directions can be set on the nozzle 231 to spray water in all directions and increase the range of water rinsing.

[0065] The flushing nozzle 22 includes an upwardly extending nozzle orifice 223. Specifically, the flushing nozzle 22 includes a cylindrical or block-shaped nozzle body 221, and the nozzle orifice 223 is disposed on the nozzle body 221. The flushing nozzle 22 or the nozzle body 221 is detachably installed in the mounting cavity 211 and can be pulled out of the mounting cavity 211 for easy maintenance and replacement. The nozzle orifice 223 is located in the mounting hole 12.

[0066] A nozzle water supply channel 224 and a nozzle head water supply channel 225 are formed between the outer peripheral surface of the flushing nozzle 22 or nozzle body 221 and the cavity wall of the mounting cavity 211. The nozzle water supply channel 224 and the nozzle head water supply channel 225 are independent of each other. The nozzle water supply channel 224 and the nozzle head water supply channel 225 can be grooves provided on the outer peripheral surface of the flushing nozzle 22 or grooves provided on the cavity wall of the mounting cavity 211.

[0067] The water supply channel 224 of the nozzle is connected to the nozzle 223, and the inlet of the water supply channel 224 faces the installation channel 11 or is located in the installation channel 11. It can be connected to the control water valve 4 via a water supply hose 6. The water supply hose 6 passes through the installation channel 11 and connects to the water supply channel 224. After the control water valve 4 opens the water supply path or valve to the nozzle 223, water flows through the water supply hose 6 and the water supply channel 224 to the nozzle 223, and is finally sprayed out through the nozzle 223 to wash the private parts of the body. The water pressure can be set as needed.

[0068] The water supply channel 225 of the showerhead is connected to the flushing head 23 via the channel through-hole 2215. The inlet of the water supply channel 225 faces the installation channel 11 or is located within the installation channel 11. It can be connected to the control water valve 4 via a water supply hose 6. The water supply hose 6 can pass through the installation channel 11 and connect to the water supply channel 225 of the showerhead. After the control water valve 4 opens the water supply path or valve to the flushing head 23, water flows through the water supply hose 6, the water supply channel 225, and the channel through-hole 2215 to the flushing head 23, and is finally sprayed out through the showerhead 231 to flush the wall of the toilet chamber 71 of the toilet body 7. The water pressure can be set as needed.

[0069] The inlet of the nozzle water supply channel 224 and the inlet of the nozzle water supply channel 225 are respectively located on the rear wall of the mounting cavity 211.

[0070] It should be noted that the control water valve 4 has multiple independent water outlets, each of which can be controlled by a separate valve. The water spraying of the nozzle 223 and the spray head 231 is controlled independently. All water supply hoses 6 can be inserted into the installation channel 11 to connect with the inlets of the nozzle water supply channel 224 and the spray head water supply channel 225.

[0071] Therefore, the spray pipe assembly provided by the present invention integrates the rinsing nozzle 22 and the rinsing head 23, so that the water pipe can be arranged entirely in the pipe body 1, saving installation space, reducing volume, simplifying structure, and facilitating installation.

[0072] In one embodiment, such as Figure 2-6 As shown, the nozzle 223 includes a front nozzle 2231 and a rear nozzle 2232.

[0073] The nozzle water supply channel 224 includes a first water supply channel 2241 and a second water supply channel 2242 that are independent of each other.

[0074] The flushing nozzle 22 is provided with independent nozzle water chambers 2211 and nozzle water channels 2212.

[0075] The nozzle water chamber 2211 connects the first water supply channel 2241 to the front spray hole 2231, and the nozzle water channel 2212 connects the second water supply channel 2242 to the rear spray hole 2232. In this embodiment, the spray hole 223 includes a front spray hole 2231 and a rear spray hole 2232. The front spray hole 2231 is basically located in the middle of the nozzle panel 222, and the rear spray hole 2232 is located behind the front spray hole 2231. In use, the front spray hole 2231 is mainly used to rinse the private parts in front of the anus, and the rear spray hole 2232 is mainly used to rinse the anal area. Preferably, the diameter of the front spray hole 2231 is larger than the diameter of the rear spray hole 2232.

[0076] Accordingly, the nozzle water supply channel 224 includes a first water supply channel 2241 and a second water supply channel 2242, which are independent of each other. The first water supply channel 2241, the second water supply channel 2242, and the nozzle water supply channel 225 are arranged independently and at intervals. The inlets of the first water supply channel 2241 and the second water supply channel 2242 are both facing the installation channel 11 or located in the installation channel 11. The inlets of the first water supply channel 2241 and the second water supply channel 2242 can each be connected to the control water valve 4 via a water supply hose 6 to achieve independent water supply.

[0077] The flushing nozzle 22 is provided with a nozzle water chamber 2211 and a nozzle water channel 2212. Specifically, the nozzle water chamber 2211 and the nozzle water channel 2212 are located in the nozzle body 221. The nozzle water chamber 2211 has a relatively large volume and is located in the middle of the nozzle body 221. The nozzle water channel 2212 is located on one side of the nozzle water chamber 2211 and is relatively narrow, which is beneficial for maintaining water pressure. The upper end of the nozzle water chamber 2211 communicates with the front spray hole 2231, and the upper end of the nozzle water channel 2212 communicates with the rear spray hole 2232.

[0078] The nozzle body 221 is provided with a water chamber connecting hole 2213 and a water channel connecting hole 2214. The first water supply channel 2241 is connected to the nozzle water chamber 2211 through the water chamber connecting hole 2213. The second water supply channel 2242 is connected to the second water supply channel 2242 through the water channel connecting hole 2214.

[0079] When water needs to be sprayed from the front nozzle 2231 for rinsing, the control water valve 4 opens the corresponding water path or valve, and water enters the nozzle water chamber 2211 through a water supply hose 6, the first water supply channel 2241 and the water chamber connecting hole 2213, and then sprays out from the front nozzle 2231.

[0080] When water needs to be sprayed from the rear nozzle 2232 for rinsing, the control water valve 4 opens the corresponding water passage or valve, and water enters the nozzle water passage 2212 through a water supply hose 6, a second water supply channel 2242 and a water passage connecting hole 2214, and then sprays out from the rear nozzle 2232.

[0081] In this embodiment, the water paths of the front nozzle 2231 and the rear nozzle 2232 can be controlled independently.

[0082] In one embodiment, such as Figure 3-4 and Figure 6 As shown, the second water supply channel 2242 is located above the first water supply channel 2241, and the nozzle water supply channel 225 is located between the first water supply channel 2241 and the second water supply channel 2242.

[0083] In this embodiment, the first water supply channel 2241 is positioned at a lower level, which allows for an appropriate increase in the height and volume of the nozzle water chamber 2211. Water entering the nozzle water chamber 2211 experiences a buffering and pressure-reducing effect, preventing high-pressure water from directly impacting the front nozzle 2231. Since the rear nozzle 2232 requires slightly higher water pressure, positioning the second water supply channel 2242 at a higher level shortens the length of the nozzle water channel 2212, facilitating rapid water ejection through the rear nozzle 2232.

[0084] In one embodiment, such as Figure 3-4 and Figure 6 As shown, the nozzle water supply channel 224 and the nozzle water supply channel 225 are respectively channel grooves provided on the circumferential surface of the flushing nozzle 22.

[0085] In this embodiment, independent flow channel grooves are pre-formed on the circumferential surface of the rinsing nozzle 22, and the flow channel grooves are recesses. Specifically, the flow channel grooves are set on the circumferential surface of the nozzle body 221.

[0086] If necessary, a flow channel groove can be recessed on the circumferential surface of the flushing nozzle 22 or the nozzle body 221. Alternatively, if necessary, raised ribs can be arranged at intervals on the circumferential surface of the flushing nozzle 22 or the nozzle body 221, and a flow channel groove is formed between two adjacent raised ribs.

[0087] After the flushing nozzle 22 is installed into the mounting cavity 211, the groove wall of the flow channel is sealed to the cavity wall of the mounting cavity 211, thereby forming the corresponding nozzle water supply channel 224 and the nozzle water supply channel 225.

[0088] The nozzle water supply channel 224 and the nozzle water supply channel 225 are two independent flow channels. The first water supply channel 2241 and the second water supply channel 2242 of the nozzle water supply channel 224 are also two independent flow channels.

[0089] In one embodiment, the flow channel is a closed-loop groove or a spiral groove surrounding the circumferential surface of the flushing nozzle 22.

[0090] In this embodiment, each flow channel groove is selected as a ring-shaped groove, which is arranged around the circumference of the flushing nozzle 22 and is a closed-loop structure.

[0091] Each flow channel groove can also be selected as a spiral groove, which surrounds the circumferential surface of the flushing nozzle 22 and extends spirally in the up-down direction.

[0092] The arrangement of closed-loop grooves or spiral grooves can satisfy different layout methods.

[0093] If necessary, the water supply channel 225 of the nozzle can be configured as a closed-loop groove to guide water from the inlet located behind the mounting cavity 211 to the flow channel through hole 2215 on the front side, and then into the rinsing nozzle 23. Excess water circulates through the closed-loop groove.

[0094] As needed, the nozzle water supply channel 224 (first water supply channel 2241 and second water supply channel 2242) can be configured as a spiral groove to guide water to flow upward to the nozzle 223 at the top.

[0095] In one embodiment, such as Figure 3-4 and Figure 6 As shown, sealing rings 226 are respectively provided on the upper and lower sides of the nozzle water supply channel 224 and the nozzle water supply channel 225, and the sealing rings 226 are in sealing contact with the cavity wall of the mounting cavity 211.

[0096] In this embodiment, sealing rings 226 are respectively provided on the upper and lower sides of the nozzle water supply channel 224 and the spray head water supply channel 225 to seal the water in each channel and prevent water mixing or leakage.

[0097] Specifically, a sealing ring 226 is provided on the upper and lower sides of the first water supply channel 2241, the second water supply channel 2242, and the nozzle water supply channel 225, respectively.

[0098] Each sealing ring 226 protrudes from the circumferential surface of the flushing nozzle 22 or nozzle body 221. The sealing ring 226 serves as the groove wall of each flow channel, eliminating the need to create grooves or ribs on the circumferential surface of the flushing nozzle 22 or nozzle body 221. A flow channel groove is formed between two adjacent sealing rings 226, improving the sealing effect and facilitating the formation of the first water supply channel 2241, the second water supply channel 2242, and the nozzle water supply channel 225.

[0099] In one embodiment, a positioning groove is provided on the cavity wall of the mounting cavity 211 corresponding to the position of each sealing ring 226, and each sealing ring 226 is at least partially assembled in the positioning groove.

[0100] In this embodiment, six positioning grooves are correspondingly arranged on the cavity wall of the mounting cavity 211 to limit the six sealing rings 226. The edge of each sealing ring 226 is located in a positioning groove, achieving a sealing connection and improving the installation stability of the sealing rings 226.

[0101] In one embodiment, such as Figure 2 and Figure 5 As shown, the inlet of the nozzle water supply channel 224 is connected to a nozzle water supply pipe head 25, and the inlet of the nozzle water supply channel 225 is connected to a nozzle water supply pipe head 26. Both the nozzle water supply pipe head 25 and the nozzle water supply pipe head 26 are located in the installation channel 11.

[0102] The nozzle water supply pipe head 25 is connected to the inlet of the nozzle water supply channel 224. It is located in the installation channel 11, which facilitates connection to the control water valve 4 via the water supply hose.

[0103] When the nozzle water supply channel 224 includes a first water supply channel 2241 and a second water supply channel 2242, the nozzle water supply head 25 correspondingly includes a first water supply head 251 and a second water supply head 252. The first water supply head 251 is connected to the inlet of the first water supply channel 2241, and the second water supply head 252 is connected to the inlet of the second water supply channel 2242. Both the first water supply head 251 and the second water supply head 252 are located in the installation channel 11, facilitating connection to the control water valve 4 via a water supply hose.

[0104] The nozzle water supply pipe head 26 is connected to the inlet of the nozzle water supply channel 225 and is located in the installation channel 11, which facilitates connection to the control water valve 4 via the water supply hose.

[0105] In one embodiment, such as Figure 3-4As shown, the top of the flushing nozzle 22 has a nozzle panel 222, and the nozzle orifice 223 is disposed on the nozzle panel 222.

[0106] In this embodiment, a nozzle panel 222 is provided on the top of the rinsing nozzle 22. A nozzle orifice 223 is provided on the nozzle panel 222.

[0107] Specifically, the nozzle panel 222 is connected to the top of the nozzle body 221. After assembly, the nozzle panel 222 is located in the mounting hole 12 at the front end of the tube body 1. The top surface of the nozzle panel 222 smoothly transitions with the top surface of the tube body 1, avoiding an overly abrupt connection. In one embodiment, such as... Figure 1-2 As shown, the tube body 1 is an arc-shaped bend. When the tube body 1 is in the extended state, the nozzle 223 extends forward and upward at an angle.

[0108] When the pipe body 1 is driven forward and extended, the front end of the curved pipe enters the toilet chamber 71 forward and downward, causing the spray nozzle 223 to tilt forward and upward, making it easier to wash the user's private parts. At the same time, the nozzle 231 of the flushing head 23 is slightly backward, which helps to wash away the dirt adhering to the rear of the toilet chamber 71.

[0109] In one embodiment, such as Figure 1-2 As shown, the front side of the device body 21 has a mounting groove 212, in which the flushing nozzle 23 is installed. An end cap 24 is detachably connected to the front of the mounting groove 212.

[0110] In this embodiment, the flushing nozzle 23 is installed in the mounting groove 212 on the front side of the device body 21, and then the front opening of the mounting groove 212 is covered by the end cap 24, which facilitates the installation of the flushing nozzle 23 and also prevents the user from seeing the flushing nozzle 23.

[0111] like Figure 7-8 As shown, an embodiment of the present invention provides a nozzle device, including a mounting bracket 3, a control water valve 4, a drive mechanism 5, and the nozzle assembly described in any of the preceding embodiments.

[0112] The pipe body 1 is slidably connected to the mounting bracket 3.

[0113] The control water valve 4 is connected to at least two water supply hoses 6. The water supply hoses 6 pass through the installation channel 11 and are connected to the inlet of the nozzle water supply channel 224 and the inlet of the nozzle water supply channel 225 respectively.

[0114] The drive mechanism 5 is connected to the tube body 1 and is used to drive the tube body 1 to extend and retract.

[0115] The nozzle device provided by this invention is used to be installed in the rear compartment of the toilet body.

[0116] The nozzle assembly includes a mounting bracket 3, a control water valve 4, a drive mechanism 5, and a nozzle assembly.

[0117] For details on the structure, construction, and working principle of the nozzle assembly, please refer to the previous description of the nozzle assembly; it will not be repeated here.

[0118] The front end of the mounting bracket 3 has a mounting plate 31, which is used to connect to the toilet body 7. The main body of the mounting bracket 3 can be used to assemble the control water valve 4, the drive mechanism 5, and the spray nozzle assembly. The structure of the mounting bracket 3 can be designed as needed and is not limited to... Figure 7 The specific structure within.

[0119] The tube body 1 is slidably connected to the mounting bracket 3, and a guide rail or sliding pair can be configured between them.

[0120] The control water valve 4 can be connected to the mounting bracket 3. The control water valve 4 has multiple water outlets, each of which is connected to a water supply hose 6. All water supply hoses 6 pass through the mounting channel 11. The inlet of the nozzle water supply channel 224 and the inlet of the spray head water supply channel 225 are respectively connected to the corresponding water supply hoses 6. Specifically, the water supply hoses 6 can be connected to the spray head water supply pipe head 26 and the nozzle water supply pipe head 25 respectively.

[0121] The drive mechanism 5 can be a motor screw drive mechanism, piston drive mechanism or other mechanism that can drive the tube body 1 to extend and retract back and forth. Its output end is connected to the tube body 1 to drive the tube body 1 to slide back and forth relative to the mounting bracket 3, thereby realizing the extension and retraction.

[0122] In the initial state, the tube 1 is in a retracted state, with the front end of the tube 1 located behind the toilet cavity 71, and is basically stored in the rear box of the toilet body 7.

[0123] When the user needs to spray water, the button of the drive mechanism 5 is operated, and the drive mechanism 5 drives the pipe body 1 to extend forward. The front end of the pipe body 1 extends into the toilet cavity 71. The front end of the pipe body 1 is located in the toilet cavity 71 relatively close to the top. Water can be sprayed from the nozzle 223 or the spray head 231 by operating the button of the control water valve 4.

[0124] After the user finishes using the device, the corresponding water circuit can be closed by operating the button of the control water valve 4 again, and then the button of the drive mechanism 5 can be operated again to drive the pipe body 1 back to the initial position.

[0125] In one embodiment, such as Figure 7 As shown, the bottom of the tube body 1 has a tube body rack 13.

The mounting bracket 3 can be directly connected to the rear of the toilet body 7, or it can be connected to the rear casing, and the installation method can be selected according to actual needs.

[0139] In the initial state, the tube 1 is in a retracted state, with the front end of the tube 1 located behind the toilet cavity 71, and is basically stored in the rear box of the toilet body 7.

[0140] When the user needs to spray water, the button of the drive mechanism 5 is operated, and the drive mechanism 5 drives the pipe body 1 to extend forward. The front end of the pipe body 1 extends into the toilet cavity 71. The front end of the pipe body 1 is located in the toilet cavity 71 relatively close to the top. Water can be sprayed from the nozzle 223 or the spray head 231 by operating the button of the control water valve 4.

[0141] After the user finishes using the device, the corresponding water circuit can be closed by operating the button of the control water valve 4 again, and then the button of the drive mechanism 5 can be operated again to drive the pipe body 1 back to the initial position.

[0142] As needed, the above technical solutions can be combined to achieve the best technical effect.
