Description

Technical Field

[0001] This application relates to the field of bathroom equipment technology, specifically to a water spray device and a smart toilet. Background Technology

[0002] With the rapid development of smart toilet technology, its functions have evolved from basic flushing and cleaning to personalization and comfort. As one of the core modules of a smart toilet, the washing function directly affects the user experience. Consumers are increasingly demanding stability of the washing water temperature, adaptability of the water pressure, and precision of the washing location, prompting manufacturers to continuously optimize heating technology, fluid control, and nozzle design.

[0003] However, in existing technical solutions, water temperature control focuses on the stability of a single temperature, and the cleaning water temperature only supports a single constant temperature mode. It lacks a dynamic change design of alternating hot and cold temperatures, and cannot improve the cleaning effect or meet users' needs for diverse physical sensations through temperature difference stimulation. Utility Model Content

[0004] This application provides a water spray device and a smart toilet to solve the problem that the constant water temperature during washing reduces the user experience.

[0005] In a first aspect, this application provides a water spraying device, including a piping assembly, a heating element, and a control module. The piping assembly is adapted for the flow of a medium and includes an inlet end and an outlet end. The heating element is disposed on the piping assembly and is adapted to heat the medium, and the heating element is adapted to switch between an on state and a off state. The control module is electrically connected to the heating element. The control module includes a switch-changing unit, which is adapted to control the heating element to switch between the on state and the off state according to a first control command obtained; wherein the first control command is issued by a control terminal.

[0006] Beneficial effects: By controlling the intermittent on-off switching of the heating element through the switch switching unit in the control module, the water flow in the pipeline is alternately hot and cold. The temperature difference of the water flow can stimulate the contraction and relaxation of the buttock muscles, improve the cleaning effect, and at the same time meet the user's needs for diverse physical sensations, such as a warm and soothing or hot and cold alternating massage experience.

[0007] In one optional implementation, the control module further includes a switching frequency control unit, adapted to control the switching frequency of the heating element between the on state and the off state according to a acquired second control command. The second control command is issued by the control terminal.

[0008] Beneficial effects: By adjusting the switching frequency of the heating element through the switching frequency control unit (such as high-frequency rapid hot and cold alternation or low-frequency slow gradual change), users can customize the rhythm of water temperature changes to suit different scenario needs (such as rapid hot and cold switching for deep cleaning, and slow switching for relaxation care), further enriching the personalized experience.

[0009] In one optional implementation, the control module further includes a temperature control unit, adapted to control the heating temperature of the heating element according to a third control command received. The third control command is issued by the control terminal.

[0010] Beneficial effects: The heating temperature can be set through the temperature control unit, making the temperature difference range of alternating hot and cold adjustable. By adjusting the temperature difference, it can meet the different needs of users with sensitive skin and those with high tolerance, thus improving comfort and safety.

[0011] In an optional embodiment, a pressure transformer assembly is further included, disposed on the pipeline, and electrically connected to the control module. The control module further includes a pressure control unit adapted to control the injection pressure of the medium at the outlet end of the pipeline assembly according to a acquired fourth control command. The fourth control command is issued by the control terminal.

[0012] Beneficial effects: By controlling the pressure control unit to dynamically adjust the water pressure of the pressure-changing component (such as alternating high-pressure pulses and low-pressure slow flow), combined with alternating hot and cold water temperatures, a dual-dimensional stimulation of "temperature + pressure" is formed, which enhances cleaning efficiency and simulates a variety of massage techniques, expanding the functional scenarios.

[0013] In one optional embodiment, the system further includes a drive assembly and a nozzle assembly. The drive assembly is electrically connected to the control module. The nozzle assembly is connected to the drive end of the drive assembly, and the drive assembly is adapted to drive the nozzle assembly to move along a first direction. The nozzle assembly includes an input end and an output end. The input end of the nozzle assembly is connected to the outlet end of the pipeline assembly, and the output end of the nozzle assembly is adapted to output the medium in the pipeline assembly.

[0014] Beneficial effects: The movable nozzle assembly allows for adjustable water flow coverage, avoiding blind spots caused by fixed nozzles. It is especially suitable for users of different body types, ensuring precise water flow to target areas and improving cleaning effectiveness and versatility.

[0015] In one optional implementation, the control module further includes a speed control unit adapted to control the speed at which the nozzle assembly moves along the first direction according to a fifth control command. The fifth control command is issued by the control terminal.

[0016] Beneficial effects: By adjusting the movement speed of the nozzle assembly (e.g., rapid scanning or slow spot rinsing) via the speed control unit, the residence time of the water flow in specific areas can be controlled. Specifically, rapid movement enables large-area cleaning, while slow movement enhances the cleaning power of localized areas, meeting users' needs for gentle care and improving safety during use.

[0017] In one optional implementation, the control module further includes a distance control unit, adapted to control the nozzle assembly to move a distance along the first direction according to a acquired sixth control command. The sixth control command is issued by the control terminal.

[0018] Beneficial effects: By controlling the nozzle movement distance through the distance control unit (such as short-distance reciprocating motion or long-distance coverage), different cleaning modes can be flexibly matched. Specifically, short-distance high-frequency movement is used for targeted cleaning, while long-distance movement is used for thorough rinsing. Combined with changes in water pressure and temperature, the user experience is optimized.

[0019] In one optional embodiment, the system further includes a valve body assembly, comprising an inlet port and multiple outlet ports, wherein the inlet port is connected to the outlet end of the piping assembly, and the multiple outlet ports are all connected to the input end of the nozzle assembly.

[0020] Beneficial effects: By switching between multiple water outlets through the valve body assembly, various spray modes can be supported. Combined with temperature and pressure changes, multiple modes can be created, significantly expanding the functional scenarios.

[0021] In an alternative implementation, a vacuum breaker is also included, connected to the water inlet of the piping assembly.

[0022] Beneficial effects: Vacuum breaker can prevent sewage backflow caused by negative pressure in pipelines, avoid water source pollution, ensure water quality and hygiene, and improve product safety and reliability.

[0023] Secondly, this application also provides a smart toilet, including a water spray device.

[0024] Beneficial effects: Smart toilets that integrate the above-mentioned water spray devices provide a variety of customizable cleaning solutions through multi-dimensional dynamic adjustment and combination of temperature, pressure, and position, breaking through the traditional single function and fully meeting the personalized needs of users.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The following is combined Figures 1 to 4 This describes an embodiment of the present application.

[0034] According to an embodiment of this application, a water spraying device is provided, including a pipeline assembly 1, a heating element 2, and a control module 3. The pipeline assembly 1 is adapted for the flow of a medium and includes an inlet end and an outlet end. The heating element 2 is disposed on the pipeline assembly 1 and is adapted to heat the medium; the heating element 2 is adapted to switch between an on state and a off state. The control module 3 is electrically connected to the heating element 2. The control module 3 includes a switch switching unit, which is adapted to control the heating element 2 to switch between an on state and a off state according to a first control command obtained; wherein the first control command is issued by a control terminal.

[0035] Understandably, the medium in the pipeline assembly 1 is water, the heating element 2 is a heater, and the control module 3 is a controller. When the water spraying device sprays water from the outlet for cleaning, the user can send a first control command to the control module 3 through the control terminal. The switch switching unit in the control module 3 controls the heating element 2 to start alternating switching, thereby realizing the alternating spraying of hot and cold water.

[0036] It should be noted that the switch unit can be configured with a main control chip and a solid-state relay. The main control chip receives user commands and outputs control signals. The solid-state relay, as the actuator, directly controls the on / off state of the heating element 2. The switch unit achieves the start and stop of the heater through open-loop control or simple closed-loop control. The user selects the "alternating hot and cold mode" via the control terminal, and the main control chip receives the first control command. The main control chip outputs a signal to the control terminal of the solid-state relay. When the solid-state relay is on, the heater continuously heats the water flow in the pipeline, and the water temperature gradually rises. When the solid-state relay is off, the heater stops working, and the water temperature naturally decreases (or mixes with cold water to cool down).

[0037] Optionally, the state of the solid-state relay can be switched cyclically by a time period preset by the main control chip (e.g., heating for 30 seconds → turning off for 20 seconds) or a user-defined rhythm, so that the water temperature changes periodically.

[0038] Optionally, the control terminal can be set as a control panel, which can be directly installed on the smart toilet or set up separately. The control terminal can also be set as an application on the user's mobile phone.

[0039] In this embodiment, the heating element 2 is intermittently turned on and off by the switch switching unit in the control module 3, so as to realize the alternating hot and cold water flow in the pipeline. The temperature difference between hot and cold water can stimulate the contraction and relaxation of the buttock muscles, improve the cleaning effect, and at the same time meet the user's needs for diverse physical sensations, such as warm and soothing or hot and cold alternating massage experience.

[0040] In one embodiment, the control module 3 further includes a switching frequency control unit, adapted to control the switching frequency of the heating element 2 between an on state and an off state according to the acquired second control command. The second control command is issued by a control terminal.

[0041] It should be noted that the switching frequency control unit can be configured as a main control chip and a timer. The main control chip controls the heating switching frequency through the timer. The solid-state relay receives signals from the main control chip and executes rapid switching of the heater. By controlling the on and off cycles of the solid-state relay through frequency parameters preset by the main control chip or input by the user, the intermittent start and stop of the heater can be achieved.

[0042] In this embodiment, the switching frequency of the heating element 2 is adjusted by the switching frequency control unit (such as high-frequency rapid hot and cold alternation or low-frequency slow gradual change), so that the user can customize the rhythm of water temperature change to adapt to different scenario needs (such as rapid hot and cold switching for deep cleaning, and slow switching for relaxation care), further enriching the personalized experience.

[0043] In one embodiment, the control module 3 further includes a temperature control unit, adapted to control the heating temperature of the heating element 2 according to the acquired third control command. The third control command is issued by the control terminal.

[0044] It should be noted that the temperature control unit can be configured with an NTC (Negative Temperature Coefficient) thermistor and a PID (Proportional-Integral-Derivative) controller. The NTC thermistor is embedded in the pipeline to detect the real-time water temperature, while the PID controller, integrated into the main control chip, can adjust the heating power based on the temperature difference. The NTC thermistor feeds the water temperature back to the PID controller, compares it with the user-set temperature, and adjusts the heater power through the PID algorithm to achieve temperature difference range control for alternating hot and cold water.

[0045] In this embodiment, the heating temperature can be set through the temperature control unit, making the temperature difference range of alternating hot and cold adjustable. By adjusting the temperature difference, the different needs of users with sensitive skin and those with strong tolerance can be met, thereby improving comfort and safety.

[0046] In one embodiment, a pressure transformer assembly 4 is further included, disposed on the pipeline, and electrically connected to the control module 3. The control module 3 further includes a pressure control unit, adapted to control the jet pressure of the medium at the outlet end of the pipeline assembly 1 according to a fourth control command. The fourth control command is issued by a control terminal.

[0047] It should be noted that the pressure transformer assembly 4 consists of a diaphragm pump and a frequency converter. The frequency converter adjusts the diaphragm pump motor speed to change the water pressure. The diaphragm pump pressure control unit includes a pressure sensor installed at the outlet of the pipeline to detect the water pressure. The pressure sensor provides real-time feedback of the water pressure to the main control chip, which then adjusts the diaphragm pump motor speed via the frequency converter according to the user-defined pressure mode.

[0048] In this embodiment, the pressure control unit controls the pressure transformer 4 to dynamically adjust the water pressure (such as alternating high-pressure pulses and low-pressure slow flow), and combined with alternating hot and cold water temperatures, to form a dual-dimensional stimulation of "temperature + pressure", which enhances cleaning efficiency and simulates various massage techniques, expanding the functional scenarios.

[0049] In one embodiment, the system further includes a drive assembly 5 and a nozzle assembly 6. The drive assembly 5 is electrically connected to the control module 3. The nozzle assembly 6 is connected to the drive end of the drive assembly 5. The drive assembly 5 is adapted to drive the nozzle assembly 6 to move along a first direction X. The nozzle assembly 6 includes an input end and an output end. The input end of the nozzle assembly 6 is connected to the water outlet end of the pipeline assembly 1, and the output end of the nozzle assembly 6 is adapted to output the medium in the pipeline assembly 1.

[0050] In this embodiment, the movable nozzle assembly 6 makes the water flow coverage area adjustable, avoiding cleaning blind spots caused by a fixed nozzle. This is especially suitable for users of different body types, ensuring that the water flow accurately targets the intended area, improving cleaning effectiveness and versatility.

[0051] In one embodiment, the control module 3 further includes a speed control unit adapted to control the speed at which the nozzle assembly 6 moves along the first direction X according to the acquired fifth control command. The fifth control command is issued by a control terminal.

[0052] It should be noted that the drive component 5 can be set as a stepper motor, the nozzle component 6 is the nozzle in the smart toilet, and the speed control unit includes an encoder. The main control chip sends a pulse frequency signal to the stepper motor driver according to the user-set movement speed to control the motor speed. The encoder monitors the actual rotation speed in real time and corrects errors through closed-loop feedback to ensure that the nozzle moves at a constant or variable speed.

[0053] In this embodiment, the moving speed of the nozzle assembly 6 is adjusted by the speed control unit (e.g., rapid scanning or slow spot rinsing) to control the residence time of the water flow in a specific area. Specifically, rapid movement achieves large-area cleaning, while slow movement enhances local cleaning intensity, meeting the user's need for gentle care and improving safety.

[0054] In one embodiment, the control module 3 further includes a distance control unit, adapted to control the nozzle assembly 6 to move a distance along a first direction X according to a acquired sixth control command. The sixth control command is issued by a control terminal.

[0055] It should be noted that the distance control unit includes a Hall sensor and limit switches. The Hall sensor detects the nozzle's movement distance. The limit switches allow setting the start and end points of the nozzle's movement. By setting the movement distance, the main control chip uses the displacement signal fed back from the Hall sensor to control the stepper motor's step count, achieving precise positioning. The limit switches prevent the nozzle from overtraveling, ensuring a safe movement range.

[0056] In this embodiment, the distance of the spray head movement is controlled by a distance control unit (e.g., short-distance reciprocating motion or long-distance coverage) to flexibly match different cleaning modes. Specifically, short-distance high-frequency movement is used for targeted cleaning, while long-distance movement is used for thorough rinsing. Combined with changes in water pressure and temperature, the user experience is optimized.

[0057] In one embodiment, the system further includes a valve body assembly 7, which includes an inlet port and multiple outlet ports. The inlet port is connected to the outlet end of the pipeline assembly 1, and the multiple outlet ports are all connected to the input end of the nozzle assembly 6.

[0058] In this embodiment, multiple water outlets can be switched via valve body assembly 7, supporting various water spray modes. By combining temperature and pressure changes, multiple modes can be created, significantly expanding the functional scenarios.

[0059] Optionally, valve body assembly 7 can be configured as a switching valve or a water distribution valve.

[0060] In one embodiment, a vacuum breaker 8 is also included, which is connected to the water inlet of the piping assembly 1.

[0061] In this embodiment, the vacuum breaker 8 can prevent sewage backflow caused by negative pressure in the pipeline, avoid water pollution, ensure water quality and hygiene, and improve product safety and reliability.

[0062] In one embodiment, the piping assembly 1 includes a diaphragm pump inlet pipe, a diaphragm pump outlet pipe, a heater outlet pipe, a posterior wash inlet pipe, and a feminine wash inlet pipe. The diaphragm pump inlet pipe is connected to the vacuum breaker 8 and the input terminal of the transformer assembly 4; the diaphragm pump outlet pipe is connected to the output terminal of the transformer assembly 4 and the heating element 2; the heater outlet pipe is connected to the heating element 2 and the valve body assembly 7; the posterior wash inlet pipe is connected to the nozzle assembly 6 and the valve body assembly 7; and the feminine wash inlet pipe is connected to the nozzle assembly 6 and the valve body assembly 7.

[0063] Optionally, the nozzle assembly 6 is provided with a posterior wash port and a feminine wash port on the nozzle, which are used to spray water from the posterior wash inlet pipe and the feminine wash inlet pipe, respectively.

[0064] In one embodiment, such as Figure 4 As shown, the operation flow of the water spray device is as follows: According to the acquired first control command, the heating element 2 is controlled to switch between the on and off states. According to the acquired second control command, the switching frequency of the heating element 2 between the on and off states is controlled. According to the acquired third control command, the heating temperature of the heating element 2 is controlled.
