Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a human body spray washing device for an intelligent toilet. Background Technology

[0002] Existing smart toilets' human body washing devices have multiple water outlets, including posterior wash, feminine wash, and self-cleaning outlets, resulting in numerous cleaning pipes that occupy space and affect the layout. Furthermore, switching between these cleaning pipes requires the installation of switching valves and corresponding switching valve motors, further increasing space requirements and costs. In addition, to meet water efficiency and user experience requirements, the water outlets of posterior wash or feminine wash nozzles are often made very small, making them prone to clogging. Since the posterior wash or feminine wash nozzles are always fixedly connected to their respective pipes, it is difficult to remove blockages when they occur. Summary of the Invention

Detailed Implementation

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the human body spray washing device of the intelligent toilet of the present invention is not limited to the embodiments.

[0045] Example 1

[0046] Please see Figures 1 to 13 As shown, the human body spray washing device of a smart toilet in this embodiment includes:

[0047] Support 1;

[0048] The spray bar 2 is slidably mounted on the support 1. The spray bar 2 includes a first rod body 21 and a second rod body 22 slidably connected to the first rod body 21. The first rod body 21 is provided with at least a first nozzle 211 and a second nozzle 212. At least one of the first nozzle 211 and the second nozzle 212 is used to clean the human body. The second rod body 22 has a water inlet channel 221.

[0049] The first drive mechanism 3 is connected to the second rod 22. The first drive mechanism 3 drives the first rod 21 to move through the second rod 22, thereby causing the spray bar 2 to slide between the extended position and the retracted position relative to the support 1. When the spray bar 2 slides to the extended position, it can clean the human body.

[0050] Under the action of external force, the second rod 22 can slide relative to the first rod 21 so that the water inlet channel 221 can be switched to communicate with the first nozzle 211 or the second nozzle 212.

[0051] In this embodiment, the first nozzle 211 and the second nozzle 212 share the same water inlet channel 221. The second rod 22 can slide relative to the first rod 21 under the action of external force so that the water inlet channel 221 can switch to connect the first nozzle 211 and the second nozzle 212. This simplifies the pipeline design and eliminates the need for additional switching valves and corresponding switching valve motors, thereby greatly reducing the space occupied by the human body spraying device and reducing product costs.

[0052] Please see Figures 1 to 13As shown, in this embodiment, the support 1 is provided with a first limiting member 11 and a second limiting member 12. When the first driving mechanism 3 drives the spray rod 2 to slide to the extended position, the first rod body 21 is limited and engaged with the first limiting member 11. The first driving mechanism 3 provides the external force to drive the second rod body 22 to slide relative to the first rod body 21 so that the water outlet end of the water inlet channel 221 (not shown in the figure) can switch from being connected to the first nozzle 211 to being connected to the second nozzle 212. When the first driving mechanism 3 drives the spray rod 2 to slide to the retracted position, the first rod body 21 is limited and engaged with the second limiting member 12. The first driving mechanism 3 provides the external force to drive the second rod body 22 to slide relative to the first rod body 21 so that the water outlet end of the water inlet channel 221 can switch from being connected to the second nozzle 212 to being connected to the first nozzle 211. In this embodiment, the first driving mechanism 3 is not only used to drive the spray bar 2 to slide relative to the support 1 between the extended position and the retracted position, but also to drive the second rod 22 to slide relative to the first rod 21 so that the water inlet channel 221 switches between the first nozzle 211 and the second nozzle 212, which can further reduce the space occupied by the human body spraying device and reduce costs. In this embodiment, the extended position of the spray bar 2 refers to the position where the first driving mechanism drives the first rod 21 to slide through the second rod 22 to the position where it is limited and engaged with the first limiting member 11, and the retracted position of the spray bar 2 refers to the position where the first driving mechanism drives the first rod 21 to slide through the second rod 22 to the position where it is limited and engaged with the second limiting member 12.

[0053] Please see Figure 2 , Figure 4 and Figures 7 to 13As shown, in this embodiment, the first nozzle 211 is used for self-cleaning of the spray bar 2, the second nozzle 212 is used for posterior washing, and the first rod body 21 is also provided with a third nozzle 213 for feminine washing. The first nozzle 211, the second nozzle 212 and the third nozzle 213 are arranged sequentially from back to front along the spray bar 2 (the spray bar 2 extends from back to front during the extension process) on the first rod body 21. When the spray bar 2 slides to the extended position, the first driving mechanism 3 provides an external force to drive the second rod body 22 to slide relative to the first rod body 21 so that the water outlet end of the water inlet channel 221 can be switched sequentially from being connected to the first nozzle 211 to being connected to the second nozzle 212 and the third nozzle 213. When the spray bar 2 slides to the retracted position, the first driving mechanism 3 provides an external force to drive the second rod body 22 to slide relative to the first rod body 21 so that the water outlet end of the water inlet channel 221 can be switched sequentially from being connected to the third nozzle 213 to being connected to the second nozzle 212 and the first nozzle 211, or can be switched from being connected to the second nozzle 212 to being connected to the first nozzle 211. In this embodiment, the first driving mechanism 3 can drive the second rod 22 to slide relative to the first rod 21 so that the water inlet channel 221 switches to connect the first nozzle 211, the second nozzle 212 and the third nozzle 213. The first nozzle 211, the second nozzle 212 and the third nozzle 213 share the same water inlet channel 221, which can simplify the pipeline design and eliminate the need for additional switching valves and corresponding switching valve motors, thereby greatly reducing the space occupied by the human body spraying device and reducing product costs.

[0054] In this embodiment, during the process of the spray bar 2 sliding from the retracted position to the extended position, the first nozzle 211 is connected to the water inlet channel 221, and the water inlet channel 221 is controlled to enter water to self-clean the spray bar 2. In this embodiment, the spray bar 2 is self-cleaned during the extension process, and cold water in the water inlet channel 221 can also be removed, so that the spray bar 2 can directly spray and wash the human body after sliding to the extended position, thereby saving time.

[0055] Please see Figures 3 to 13As shown, in this embodiment, the spray bar 2 further includes a sleeve 23 slidably disposed on the support 1. The first rod body 21 is fixedly installed in the sleeve 23, and the second rod body 22 is slidably disposed in the sleeve 23. The upper opening of the first nozzle 211 (not shown in the figure), the upper opening of the second nozzle 212 (not shown in the figure), and the upper opening of the third nozzle 213 (not shown in the figure) respectively form water outlets. The lower opening of the first nozzle (not shown in the figure), the lower opening of the second nozzle 212 (not shown in the figure), and the lower opening of the third nozzle 213 (not shown in the figure) respectively form water inlets. The top wall of the front end of the sleeve 23 is provided with relief holes 231 corresponding to the water outlets of the second nozzle 212 and the third nozzle 213, so that the water flow in the second nozzle 212 or the third nozzle 213 can be sprayed to the corresponding part of the human body through the relief holes 231. In this embodiment, the spray bar 2 is provided with a sleeve 23, and the first rod body 21 is fixedly installed in the sleeve 23, while the second rod body 22 is slidably installed in the sleeve 23, making the spray bar 2 more aesthetically pleasing and robust in its overall structure.

[0056] In this specific implementation, the first rod 21 is located above the second rod 22, and an opening 232 is provided on the bottom wall of the front end of the sleeve 23. The water inlet ends of the first nozzle 211, the second nozzle 212, and the third nozzle 213 can all be connected to the opening 232, and the flow cross-sectional area of ​​the opening 232 is greater than the flow cross-sectional area of ​​any one of the first nozzle 211, the second nozzle 212, and the third nozzle 213. Specifically, when the first nozzle 211, the second nozzle 212, or the third nozzle 213 is not connected to the water outlet end of the water inlet channel 221, the impurities blocked on the nozzles can be smoothly discharged through the opening 232 by flushing the first nozzle 211, the second nozzle 212, or the third nozzle 213 with water in reverse. In this embodiment, by opening an opening 232 on the bottom wall at the front end of the sleeve 23, when the user cleans the first nozzle 211, the second nozzle 212 and the third nozzle 213, the cleaning water can flow out through the opening 232, which can maintain the overall appearance of the spray bar 2 and does not affect the removal of blockages at the first nozzle 211, the second nozzle 212 or the third nozzle 213.

[0057] Please see Figures 3 to 13As shown, in this embodiment, a blocking part 214 is provided on the first rod body 21 corresponding to the water outlet end of the first nozzle 211. The water flowing out of the first nozzle 211 self-cleans the second nozzle 212 and the third nozzle 213 on the spray rod 2 under the action of the blocking part 214. The water flow sprayed from the first nozzle 211 flows to the second nozzle 212 and the third nozzle 213 due to the obstruction of the blocking part 214, thereby self-cleaning the second nozzle 212 and the third nozzle 213; the second rod body 22 is straight The second rod 22 is slidably connected to the first rod 21. The second rod 22 has a first sliding groove 222, and the first rod 21 has a first sliding rib 215 that slides within the first sliding groove 222. A bushing 13 is provided at the front end of the support 1, and a sleeve 23 is slidably fitted within the bushing 13. The second rod 22 is slidably connected to the support 1, and the second rod 22 has a second sliding groove (not shown in the figure). The support 1 has a second sliding rib (not shown in the figure) that slides within the second sliding groove. In other embodiments, the second rod 22 may also be indirectly slidably connected to the first rod 21 via the sleeve 23.

[0058] Please see Figures 7 to 13 As shown, in this embodiment, when the second rod 22 slides relative to the first rod 21, the outlet end of the water inlet channel 221 is switched to be connected to the water inlet end of the first nozzle 211, the water inlet end of the second nozzle 212, or the water inlet end of the third nozzle 213. The spray bar 2 also includes a sealing ring 24 disposed at the outlet end of the water inlet channel 221 and an elastic member 25 abutting between the sealing ring 24 and the second rod 22. The elastic member 25 is specifically a spring. The sealing ring 24 can be tightly pressed against the first rod 21 under the action of the elastic member 25. The outlet end of the water inlet channel 221 is sealed with the first nozzle 211, the second nozzle 212, or the third nozzle 213 through the sealing ring 24. Since the sealing ring 24 in this embodiment can be tightly pressed against the first rod 21 under the action of the elastic member 25, the outlet end of the water inlet channel 221 can be reliably sealed with the first nozzle 211, the second nozzle 212, or the third nozzle 213 through the sealing ring 24.

[0059] Please see Figures 7 to 13 As shown, in this embodiment, a positioning structure is provided between the first rod 21 and the second rod 22. When the second rod 22 slides relative to the first rod 21 to the point where the water inlet channel 221 communicates with the first nozzle 211, the second nozzle 212, or the third nozzle 213, the positioning structure enables sliding positioning. This embodiment, by providing a positioning structure between the first rod 21 and the second rod 22, allows the second rod 22 to accurately slide to the corresponding position and be positioned relative to the first rod 21, thereby ensuring reliable communication between the water inlet channel 221 and the first nozzle 211, the second nozzle 212, or the third nozzle 213.

[0060] In this specific implementation, the positioning structure includes an elastic arm 216 on the first rod 21 and a positioning groove 223 on the second rod 22. The elastic arm 216 has a positioning protrusion 2161 that can engage with the positioning groove 223. The positioning groove 223 includes a first positioning groove 2231, a second positioning groove 2232, and a third positioning groove 2233. The elastic arm 216 is an integral structure with the first nozzle 211, the second nozzle 212, and the third nozzle 213. The elastic arm 216 can undergo a certain degree of elastic deformation relative to the first rod 21, allowing the elastic arm 216 to... The positioning protrusion 2161 can slide and engage with the first positioning groove 2231, the second positioning groove 2232, or the third positioning groove 2233 as the second rod 22 slides relative to the first rod 21. When the water inlet channel 221 is connected to the first nozzle 211, the positioning protrusion 2161 engages with the first positioning groove 2231. When the water inlet channel 221 is connected to the second nozzle 212, the positioning protrusion 2161 engages with the second positioning groove 2232. When the water inlet channel 221 is connected to the third nozzle 213, the positioning protrusion 2161 engages with the third positioning groove 2233. In other embodiments, the positioning protrusion can be provided on the second rod, and the elastic arm can be provided with a positioning groove that engages with the positioning protrusion. The positioning groove 223 also includes the first positioning groove, the second positioning groove, and the third positioning groove.

[0061] Please see Figure 3 , Figure 4 and Figures 7 to 13 As shown, in this embodiment, the first driving mechanism 3 includes a motor 31 and a gear set 32. The motor 31 is connected to the second rod 22 via the gear set 32. The second rod 22 is provided with a rack 224 that can mesh with the gear set 32. The side wall of the sleeve 23 is provided with a clearance notch 233 corresponding to the gear set 32. The gears of the gear set 32 ​​pass through the clearance notch 233 and mesh with the rack 224 on the second rod 22. In other embodiments, the first driving mechanism can also be a cylinder first driving mechanism; or, the first driving mechanism includes a motor and a lead screw transmission mechanism, with the motor connected to the second rod via the lead screw transmission mechanism, which can also achieve the purpose of the present invention.

[0062] In this embodiment, a control valve (not shown in the figure) is also included. The water inlet channel 221 is connected to the water source through the control valve. The control valve is used to control whether the water inlet channel 221 is connected to or disconnected from the water source, that is, the control valve is used to control whether water enters the water inlet channel 221.

[0063] The working principle of this embodiment is briefly described as follows:

[0064] Please see Figure 7As shown, in the initial state, the spray bar 2 is in the retracted position, the water inlet channel 221 is connected to the first nozzle 211, the positioning protrusion 2161 is engaged with the first positioning groove 2231, and the control valve controls the water inlet channel 221 to disconnect from the water source.

[0065] When a posterior wash is required, such as Figure 8 and Figure 9 As shown, the first drive mechanism 3 drives the second rod 22 to move forward, thereby driving the spray bar 2 to slide relative to the support 1 towards the extended position. During the process of the spray bar 2 sliding from the retracted position to the extended position, water is controlled to enter the water inlet channel 221 to self-clean the spray bar 2, and after the self-cleaning of the spray bar 2 is completed, the water inlet channel 221 is controlled to stop the water flow; when the spray bar 2 slides to the extended position, as... Figure 2 As shown, the first rod 21 is engaged with the first limiting member 11. At this time, the first driving mechanism 3 continues to drive the second rod 22 to move forward. The first rod 21 cannot extend further due to the obstruction of the first limiting member 11, thereby causing the second rod 22 to slide relative to the first rod 21. Figure 10 As shown ( Figure 10 (A partial view of the human body spray washing device) The water inlet channel 221 is switched to communicate with the second nozzle 212, and the positioning protrusion 2161 is also switched to engage with the second positioning groove 2232. At this time, water is controlled to enter the water inlet channel 221 to perform buttock washing.

[0066] When a gynecological wash is required, such as Figure 11 As shown ( Figure 11 (Partial view of the human body spray washing device) Figure 10 In the current state, the first drive mechanism 3 continues to drive the second rod 22 to move forward, causing the second rod 22 to slide relative to the first rod 21 until the water inlet channel 221 connects with the third nozzle 213. The positioning protrusion 2161 then engages with the third positioning groove 2233, thus performing feminine wash. After the feminine wash is completed, the water inlet channel 221 is stopped, and the first drive mechanism 3 drives the second rod 22 to move in the opposite direction, driving the spray bar 2 to slide relative to the support 1 towards the retracted position. Figure 12 As shown, when the spray bar 2 slides to the retracted position, the first rod 21 engages with the second limiting member 12, and the first drive mechanism 3 continues to drive the second rod 22 to move in the opposite direction. The first rod 21, blocked by the second limiting member 12, cannot continue to retract, thus causing the second rod 22 to slide relative to the first rod 21. Figure 13 As shown, the water inlet channel 221 switches to communicate with the first nozzle 211, the positioning protrusion 2161 resets to engage with the first positioning groove 2231, the cleaning ends, and it returns to the initial state.

[0067] When only a posterior wash is needed, after the posterior wash is completed, the first drive mechanism 3 directly drives the second rod 22 to move in the opposite direction, so as to drive the spray bar 2 to slide to the retracted position.

[0068] When only feminine wash is needed, after the spray bar 2 slides to the extended position, the first drive mechanism 3 continues to drive the second rod 22 to move forward, so that the water inlet channel 221 is directly switched to connect with the third nozzle 213, thereby performing feminine wash.

[0069] In other embodiments, the first nozzle is used for self-cleaning the spray bar, and the second nozzle is used for posterior washing; or, the first nozzle is used for self-cleaning the spray bar, and the second nozzle is used for feminine washing; or, the first nozzle is used for posterior washing, and the second nozzle is used for feminine washing. Since the first nozzle and the second nozzle share the same water inlet channel, there is no need to return and repeatedly remove cold water during the posterior washing and feminine washing switching process, saving time.

[0070] In other embodiments, the positioning structure may also include an elastic arm on the second rod and a positioning groove or positioning protrusion on the first rod. The elastic arm is provided with a positioning protrusion or positioning groove that can engage with the positioning groove or positioning protrusion. The positioning groove includes a first positioning groove, a second positioning groove, and a third positioning groove. When the water inlet channel is connected to the first nozzle, the positioning protrusion engages with the first positioning groove. When the water inlet channel is connected to the second nozzle, the positioning protrusion engages with the second positioning groove. When the water inlet channel is connected to the third nozzle, the positioning protrusion engages with the third positioning groove.

[0071] Example 2

[0072] This embodiment is basically the same as Embodiment 1, except that:

[0073] In this embodiment, a second driving mechanism is also fixedly mounted on the second rod. The second driving mechanism provides external force to drive the first rod to slide relative to the second rod so that the outlet end of the water inlet channel is switched to communicate with the first nozzle, the second nozzle, or the third nozzle.

[0074] In this embodiment, when the first driving mechanism drives the spray bar to slide relative to the support to the extended position, the second driving mechanism drives the first rod to slide relative to the second rod, so that the water outlet of the water inlet channel switches to connect the second nozzle and the third nozzle, thereby cleaning the corresponding part of the human body; during the cleaning process, the spray bar remains in the extended position (i.e., the second rod and the support are relatively stationary); after the cleaning is completed, the first driving mechanism drives the spray bar to slide relative to the support to the retracted position.

[0075] In this embodiment, the extended position of the spray bar 2 refers to the position when the first drive mechanism drives the second rod 22 to slide to the foremost position, and the retracted position of the spray bar 2 refers to the position when the first drive mechanism drives the second rod 22 to slide to the rearmost position.

[0076] As can be seen from the above description of the present invention, compared with the prior art, the human body spraying device of the present invention for an intelligent toilet has a first nozzle and a second nozzle sharing the same water inlet channel. The second rod can slide relative to the first rod under the action of external force to switch the water inlet channel to connect the first nozzle and the second nozzle. This simplifies the pipeline design and eliminates the need for a separate switching valve and corresponding switching valve motor, thereby greatly reducing the space occupied by the human body spraying device and lowering the product cost. In addition, the lower opening of the first nozzle and the lower opening of the second nozzle respectively form the water inlet end. The outlet end of the water inlet channel alternately matches the lower opening of the first nozzle and the lower opening of the second nozzle. That is, the lower opening of the first nozzle and the lower opening of the second nozzle are not fixedly connected to the water inlet channel, so that when each nozzle is blocked, the blockage can be easily cleared.

[0077] The above embodiments are only used to further illustrate the human body spray washing device of an intelligent toilet of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
