Description

Technical Field

[0001] This invention relates to the technical field of intelligent toilet washer accessories, specifically to a personal hygiene spray device. Background Technology

[0002] Current smart toilet washer technology is relatively simple, using single or multiple nozzles to spray water in a straight jet without any shape change. This spray can cause a stinging sensation when it hits the skin. Furthermore, the cleaning area covered by a single jet is small, resulting in weak cleaning power. Thorough cleaning requires a large water flow and a long cleaning time, leading to unnecessary water waste. Therefore, further improvements are needed.

[0003] For an example of an intelligent toilet cleaner, please refer to Chinese Patent Application No. ZL 202121110648.6. Summary of the Invention

[0004] This invention proposes a personal hygiene spray device, in which the nozzle is equipped with a multi-hole spray path, a swirling spray path, and a straight columnar spray path. The three spray paths can achieve different water output patterns to meet diverse cleaning needs.

[0005] A personal hygiene spray device designed for this purpose includes a nozzle, which has several independently spaced water flow channels. The water flow channels include a multi-hole spray path that can spray multiple dispersed water flow simultaneously, a vortex spray path that can spray rotating water flow, and a straight columnar spray path that can spray concentrated straight water flow. The nozzle is equipped with a rotating jet assembly at the output end of the corresponding rotary water jet path for spraying out a rotating water flow. The rotating jet assembly is rotatably installed inside the nozzle. The rotary water spray path includes a water inlet channel disposed on the nozzle and connected to the water inlet end of the rotary spray assembly. The water inlet channel is provided with a sloping guide ramp to guide the liquid flow to the rotary spray assembly.

[0006] The rotary water spray path also includes a water storage cavity set in the nozzle, the water inlet channel is connected to the water storage cavity, the rotary spray assembly is rotatably set in the water storage cavity, the liquid flows through the water inlet channel to the water storage cavity and the rotary spray assembly, the rotary spray assembly rotates under the impact of the water flow and drives the water flow to rotate, the rotating water flow enters through the water inlet end of the rotary spray assembly and is finally uniformly output from the rotary spray end of the rotary spray assembly.

[0007] The rotary jet assembly includes a turbine rotor, which has a water storage groove forming a hollow water storage space and several arc-shaped blades. The arc-shaped blades are circumferentially spaced between the outer periphery of the water storage groove and the inner periphery of the water storage cavity. The water storage groove is connected to the water storage cavity. Water flows into the water storage cavity from the guide slope of the water inlet channel and impacts the arc-shaped blades of the turbine rotor, causing the turbine rotor to rotate. The turbine rotor drives the water flow to rotate, and the rotating water flow enters the water storage groove. The rotating water flow enters the interior of the water storage groove and flows to the rotary jet end of the rotary jet assembly.

[0008] The rotary jet assembly also includes a jetting element, which is oscillatingly disposed within the water storage groove of the turbine rotor; The jetting component oscillates under the influence of the rotating water flow, thereby spraying out a rotating water flow. The jetting orifice of the jetting component forms a rotating jetting end during the rotation of the jetting component.

[0009] The spraying component has a first spray channel and a second spray channel that are connected vertically. The spraying structure of the spraying component is eccentrically set, and the central axis of the first spray channel and the central axis of the second spray channel are not on the same axis.

[0010] The upper part of the spray element is sealed to the water storage groove by a sealing element.

[0011] The turbine rotor has an upwardly protruding baffle rib in its water storage groove. The central axis of the baffle rib is not on the same axis as the central axis of the water storage groove. The spray element is inclined and installed in the water storage groove. The bottom of the spray element is positioned between the baffle rib and the inner side of the water storage groove.

[0012] The turbine rotor is provided with a water inlet and a rotating shaft at its bottom. The water storage groove is connected to the water storage cavity through the water inlet. The bottom wall of the water storage cavity is provided with a connecting part. The rotating shaft is inserted into the connecting part so that the turbine rotor is rotated in the water storage cavity. The liquid in the water storage cavity impacts the turbine rotor to rotate, forming a swirling water flow. The swirling water flow flows through the water inlet and the water storage groove to the rotating spray end of the rotating spray assembly.

[0013] The linear columnar water spray path includes a first water spray column and a second water spray column installed inside the nozzle. The second water spray column and the first water spray column are arranged vertically. The volume of the first water spray column is larger than the volume of the second water spray column. Water flows through the first water spray column into the second water spray column and then sprays out. The linear column-type water spray path also includes a water inlet channel on the nozzle. The bottom of the first water spray column is suspended inside the nozzle. A lower water inlet gap is formed between the bottom of the first water spray column and the inner bottom wall of the nozzle. An upwardly protruding water-blocking rib is provided between the output end of the water inlet channel and the lower water inlet gap. An upper water inlet gap is formed between the top of the water-blocking rib and the inner top wall of the nozzle. A side water inlet gap is formed between the output end of the water inlet channel and the water-blocking rib. Water flows through the water inlet channel, the side water inlet gap, the upper water inlet gap and the lower water inlet gap in sequence into the first water spray column and the second water spray column. The water inlet channel and the water jet are connected by water-blocking ribs to form a meandering n-shaped water flow channel.

[0014] The multi-hole water spray path includes an inlet channel, an upper spray element, and a lower spray element set on the nozzle. Both the upper and lower spray elements are provided with two or more spray holes arranged horizontally. The inlet channel, the lower spray element, and the upper spray element are connected in sequence. The personal hygiene spray device also includes a housing, with the nozzle installed inside the housing. The housing is provided with clearances at the output ends of the upper spray component, the rotary spray assembly, and the linear columnar spray path. A gas-liquid mixing gap is provided between the clearance on the housing and the upper spray component for mixing air and sprayed liquid.

[0015] The nozzle includes a bottom cover and a nozzle body. The nozzle body is integrally formed with several independently spaced water flow channels, and the bottom cover is integrally formed with water-blocking ribs, the inner bottom wall of the water storage cavity and its connecting parts.

[0016] The beneficial technical effects of the present invention are as follows: The nozzle features a multi-hole spray path, a swirling spray path, and a straight columnar spray path. These three spray paths allow for different water output patterns to meet diverse cleaning needs. The swirling spray path's inlet channel is equipped with a guide ramp, precisely guiding the liquid flow to the rotating jet component. This ensures the water flow impacts the rotating jet component, allowing it to rotate smoothly and spray a swirling water stream. These three spray paths enrich the water output functionality, enhance the device's practicality and applicability, and allow users to select the appropriate water output method according to their needs, improving the user experience.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-12 A personal hygiene spray device includes a nozzle 1, which has several independently spaced water flow channels. The water flow channels include a multi-hole spray path that can spray multiple dispersed water flow simultaneously, a vortex spray path that can spray rotating water flow, and a straight columnar spray path that can spray concentrated straight water flow. The nozzle 1 is provided with a rotating jet assembly 2 at the output end of the rotary water jet path for spraying out a rotating water flow. The rotating jet assembly 2 is rotatably installed inside the nozzle 1. The rotary water spray path includes a water inlet channel 3 disposed on the nozzle 1 and connected to the water inlet end of the rotary spray assembly 2. The water inlet channel 3 is provided with a guide slope 301 to guide the liquid flow to the rotary spray assembly 2.

[0031] The nozzle 1 includes a bottom cover and a nozzle body, which are fixedly connected by a snap fastener.

[0032] The nozzle 1 is equipped with a multi-hole spray path, a swirling spray path, and a straight columnar spray path. These three spray paths can achieve different water output patterns to meet diverse cleaning needs. The inlet channel 3 of the swirling spray path is equipped with a guide slope 301, which can accurately guide the liquid flow to the rotating spray assembly 2, allowing the water flow to impact the rotating spray assembly 2 and ensuring that the rotating spray assembly 2 rotates smoothly to spray a rotating water flow. The three spray paths enrich the water output functions, improve the practicality and applicable scenarios of the device, and allow users to choose the corresponding water output mode according to their needs, thus enhancing the user experience.

[0033] The rotary water spray path also includes a water storage cavity 4 disposed in the nozzle 1. The water inlet channel 3 is connected to the water storage cavity 4. The rotary spray assembly 2 is rotatably disposed in the water storage cavity 4. The liquid flowing through the water inlet channel 3 flows to the water storage cavity 4 and the rotary spray assembly 2. The rotary spray assembly 2 rotates under the impact of the water flow and drives the water flow to rotate. The rotating water flow enters through the water inlet end of the rotary spray assembly 2 and is finally uniformly output from the rotary spray end of the rotary spray assembly 2.

[0034] A water storage cavity 4 is added to the rotary water spray path. The water inlet channel 3 is connected to the water storage cavity 4, and the rotary spray component 2 is rotatably installed in the water storage cavity 4. The water storage cavity 4 can temporarily store and buffer the liquid introduced by the water inlet channel 3, avoid water flow dispersion, and ensure that the water flow is concentrated and flows to the rotary spray component 2, so that the rotary spray component 2 rotates under the impact of the water flow and drives the water flow to rotate and enter the rotary spray component 2.

[0035] The rotating jet assembly 2 includes a turbine rotor 201, which has a water storage groove 203 forming a hollow water storage space and several arc-shaped blades 202. The several arc-shaped blades 202 are circumferentially spaced between the outer periphery of the water storage groove 203 and the inner periphery of the water storage cavity 4. The water storage groove 203 is connected to the water storage cavity 4. The water flow enters the water storage cavity 4 from the guide slope 301 of the water inlet channel 3 and impacts the arc-shaped blades 202 of the turbine rotor 201, causing the turbine rotor 201 to rotate. The turbine rotor 201 drives the water flow to rotate, and the rotating water flow enters the water storage groove 203.

[0036] The turbine rotor 201 of the rotating jet assembly 2 is equipped with a water storage groove 203 and circumferentially spaced arc-shaped blades 202. The arc-shaped blades 202 can efficiently receive the water flow guided by the guide slope 301. The impact force of the water flow drives the turbine rotor 201 to rotate stably, while simultaneously causing the water flow in the water storage cavity 4 to form a swirling flow. The water storage groove 203 forms a hollow water storage space. The rotating water flow enters the water storage groove 203 through the water inlet 208 and converges, laying a solid foundation for the subsequent jetting of the rotating water flow.

[0037] The rotary jet assembly 2 also includes a jetting element 204, which is swayed and disposed in the water storage groove 203 of the turbine rotor 201; The jetting element 204 oscillates under the influence of the rotating water flow, thereby spraying out a rotating water flow. The jetting orifice of the jetting element 204 forms a rotating jetting end during the rotation of the jetting element 204.

[0038] The spraying component 204 has a first water spray channel 205 and a second water spray channel 206 that are connected vertically. The water spraying structure of the spraying component 204 is eccentrically arranged, and the central axis of the first water spray channel 205 and the central axis of the second water spray channel 206 are not on the same axis.

[0039] The first water spray channel 205 and the second water spray channel 206 within the spray element 204 are eccentrically positioned, with their central axes not coinciding. This causes an eccentric force to be generated when the water flows within the spray element 204. This eccentric force, in conjunction with the force of the rotating water flow, further promotes the regular oscillation of the spray element 204. Simultaneously, the vertically connected first water spray channel 205 and second water spray channel 206 ensure smooth water flow without affecting the water output efficiency.

[0040] The jet component 204 is oscillatingly positioned within the water storage groove 203 of the turbine rotor 201. The rotating water flow generates a driving force that causes the jet component 204 to oscillate rhythmically. No additional power source is required; the oscillation of the jet component 204 and the rotation of the water flow are coordinated by the energy of the water flow itself, resulting in a rotating water flow. Compared to a fixed jet method, the rotating water flow provides a wider cleaning coverage and more comprehensive cleaning.

[0041] The upper part of the spray element 204 is sealed to the water storage groove 203 by a sealing element 5.

[0042] The upper part of the spray element 204 and the water storage groove 203 are sealed together by the sealing element 5, which can effectively prevent water from leaking out from the gap between the two and ensure that all water is sprayed out from the spray element 204, thus avoiding water waste.

[0043] The turbine rotor 201 has an upwardly protruding baffle 207 in the water storage groove 203. The central axis of the baffle 207 is not on the same axis as the central axis of the water storage groove 203. The spray element 204 is inclinedly arranged in the water storage groove 203, and the bottom of the spray element 204 is positioned between the baffle 207 and the inner side of the water storage groove 203.

[0044] The turbine rotor 201 is provided with a water inlet 208 and a rotating shaft 209 at its bottom. The water storage groove 203 is connected to the water storage cavity 4 through the water inlet 208. The bottom wall of the water storage cavity 4 is provided with a connecting part 401. The rotating shaft 209 is inserted into the connecting part 401 so that the turbine rotor 201 is rotated and installed in the water storage cavity 4. The liquid in the water storage cavity 4 impacts the turbine rotor 201 to rotate, forming a swirling water flow. The swirling water flow flows through the water inlet 208 and the water storage groove 203 to the rotating spray end of the rotating spray assembly 2.

[0045] The baffle 207 provides stable positioning support for the spraying part 204, preventing the spraying part 204 from shifting or falling off during the swinging process, and ensuring the stability of the swinging trajectory of the spraying part 204.

[0046] The connecting part 401 is integrally formed with the bottom cover, and the water storage cavity 4 is integrally formed with the nozzle body. Except for the rotating spray assembly 2, the other water passage structures are integrally formed with the bottom cover or nozzle body. The specific structure will not be described in detail here.

[0047] The linear columnar water spray path includes a first water spray column 10 and a second water spray column 11 disposed in the nozzle 1. The second water spray column 11 and the first water spray column 10 are arranged vertically. The volume of the first water spray column 10 is larger than the volume of the second water spray column 11. Water flows through the first water spray column 10 into the second water spray column 11 and is then sprayed out. The linear column-type water spray path also includes a water inlet channel 6 on the nozzle 1. The bottom of the first water spray column 10 is suspended inside the nozzle 1. A lower water inlet gap 7 is formed between the bottom of the first water spray column 10 and the inner bottom wall of the nozzle 1. An upwardly protruding water-blocking rib 8 is provided between the output end of the water inlet channel 6 and the lower water inlet gap 7. An upper water inlet gap 9 is formed between the top of the water-blocking rib 8 and the inner top wall of the nozzle 1. A side water inlet gap 10 is formed between the output end of the water inlet channel 6 and the water-blocking rib 8. Water flows through the water inlet channel 6, the side water inlet gap 10, the upper water inlet gap 9 and the lower water inlet gap 7 and flows into the first water spray column 10 and the second water spray column 11 in sequence. The water inlet channel 6 and the water jet are connected by a water-blocking rib 8 to form a meandering n-shaped water flow channel.

[0048] The first water jet 10 and the second water jet 11 in the straight column-type water jet path are arranged vertically, with the first water jet 10 having a larger volume, which can buffer and stabilize the water flow, ensuring that the water flows smoothly into the second water jet 11, forming a regular straight water jet. The water inlet channel 6 and the water jet are connected by water-blocking ribs 8 to form an n-shaped meandering water flow channel. The water flows through the water inlet channel 6, the side water inlet gap 10, the upper water inlet gap 9 and the lower water inlet gap 7 in sequence into the first water jet 10 and the second water jet 11. The water-blocking ribs 8 can prevent the water flow from directly impacting the water.

[0049] According to claim 1, the body-washing water spray device is characterized in that: the multi-hole water spray path includes an inlet channel 12, an upper spray element 13 and a lower spray element 14 disposed on the spray head 1, and the upper spray element 13 and the lower spray element 14 are each provided with two or more spray holes arranged horizontally; the inlet channel 12, the lower spray element 14 and the upper spray element 13 are connected in sequence; The body washing spray device also includes a housing 15, and a nozzle 1 is installed inside the housing 15. The housing 15 is provided with clearance positions at the output ends of the upper spray component 13, the rotary spray assembly 2 and the linear column spray path. A gas-liquid mixing gap 16 for mixing air and sprayed liquid is provided between the corresponding clearance position of the housing 15 and the upper spray component 13.

[0050] The nozzle 1 includes a bottom cover 101 and a nozzle body 102. The nozzle body 102 is integrally formed with several independently spaced water flow channels. The bottom cover 101 is integrally formed with a water-blocking rib 8, the inner bottom wall of the water storage cavity 4, and its connecting part 401. This effectively simplifies the structure of the entire water spraying device and facilitates the installation of corresponding components (such as the rotating spray assembly 2) between the nozzle body 102 and the bottom cover 101.

[0051] The inlet channel 12 of the multi-hole water spray path connects sequentially to the lower spray element 14 and the upper spray element 13. Both the upper spray element 13 and the lower spray element 14 are equipped with horizontal spray holes to achieve wide-area water spray and expand the cleaning coverage. The air-liquid mixing gap 16 between the clearance space of the housing 15 and the upper spray element 13 allows air to be introduced, enabling the water flow to fully mix with air before spraying out, forming a water flow with bubbles. This reduces the impact force of the water flow, making the water spray gentler and avoiding stinging sensation when sprayed on the human body, thus balancing cleaning power and comfort. The combination of wide-area water spray and bubble effect meets the need for gentle cleaning and enhances the user experience.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
