Description

Technical Field

[0001] This application belongs to the field of bathroom equipment technology, specifically referring to a flushing module and smart toilet based on a laser sensor. Background Technology

[0002] In the current field of smart bathroom appliances, the intelligent control functions of smart bathroom appliances generally rely on magnets and Hall sensors to achieve function adjustment. Using magnets and Hall sensors has problems such as high hardware costs, susceptibility to accidental touches, and complex waterproofing processes. Traditional bathroom appliances only support basic flushing functions and cannot achieve intelligent switching between multiple modes (such as water saving and cleaning). Using magnets and Hall sensors for control increases costs and the risk of failure. Furthermore, the lack of intuitive feedback mechanisms (such as light prompts) results in a poor user experience. Without adaptive water-saving algorithms, frequent use leads to water waste.

[0003] Therefore, traditional bathroom equipment has limited functions, lacks intelligent support for water conservation and cleaning, and user interaction relies on physical devices, making it inconvenient to operate. Utility Model Content

[0027] The embodiments of this application will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0028] Figure 1 This is a schematic diagram of the structure of the laser sensor-based flushing module provided in this application.

[0029] like Figure 1As shown, the flushing module includes: a power module, a laser ranging module, a control module, and a solenoid valve drive module. The power module connects to the laser ranging module, the control module, and the solenoid valve drive module, and supplies power to the solenoid valve drive module. The power module steps down the voltage before supplying power to the laser ranging module and the control module. The laser ranging module emits a laser signal and determines the distance and time of obstruction based on feedback signals, sending this information to the control module. The control module responds to the obstruction distance and time information sent by the laser ranging module and generates control information, which is then sent to the solenoid valve drive module. Based on the different obstruction distances and times received from the laser ranging module, the control module generates different control information for the solenoid valve drive module, controlling it to perform different flushing modes. The solenoid valve drive module controls the opening size and duration of the solenoid valve according to the control information sent by the control module, and the solenoid valve controls the water pipe to flush to different degrees.

[0030] Specifically, the power module is connected to AC power and converted to DC power, or directly connected to DC power. The output of the power module supplies power to the flushing module. The power module can also be connected to a large capacitor, which provides power to ensure the solenoid valve closes in the event of an abnormal power outage.

[0031] The laser ranging module includes a laser sensor and a laser information processing chip for processing distance and time information; the laser sensor includes a laser emitting unit, a laser receiving unit, and a time measuring unit, all of which are connected to the laser information processing chip; the control module can set several flushing modes and perform flushing with different amounts of water based on the number of times the laser sensor is blocked, the distance, and the time.

[0032] In this embodiment, the intensity of the laser emitted by the laser emitting unit is such that the laser emitted by the laser emitting unit is blocked within 1-100cm and reflected so that the laser receiving unit can identify it.

[0033] This embodiment uses a dTOF laser sensor as an example for explanation. Using a dTOF laser sensor allows for the acquisition of precise information such as distance.

[0034] The control module includes an MCU, whose input is connected to the laser ranging module and whose output is connected to the solenoid valve drive module. The MCU is a low-power microcontroller that integrates multi-mode functions and non-contact detection and configuration logic algorithms to control the solenoid valve drive module according to different functional modes.

[0035] In this embodiment, the solenoid valve drive module includes a solenoid valve drive circuit unit and a solenoid valve. The solenoid valve drive circuit unit controls the on / off state of the solenoid valve. The solenoid valve can be driven by an H-bridge circuit. The solenoid valve is equipped with at least a first flush volume solenoid valve and a second flush volume solenoid valve. The first flush volume solenoid valve and the second flush volume solenoid valve are used to match the flush volume in different functional modes.

[0036] like Figure 1 As shown, the flushing module further includes a voltage detection module, which is connected to the power supply module and the control module; the voltage detection module is used to detect the voltage of the power supply. The flushing module also includes an indicator light module, which is connected to the power supply module and the control module; the indicator light module is controlled by the control module and provides different light indications according to different flushing modes. The indicator light module includes LED indicators, and the control module controls the on / off state of the LED indicators to provide operational feedback and status display.

[0037] Specifically, the main functional logic of the laser sensor-based flushing module provided in this embodiment is as follows:

[0038] During use, users wave their hand in front of the laser ranging module to obtain information such as the distance, number of times, and duration of obstruction. This information is then processed by the control module's algorithm to implement the corresponding functional mode. Specifically, the obstruction time (t) and number of times (n) at different distances (d) in front of the sensor trigger the corresponding mode, allowing for configuration settings and flushing intensity adjustments. The status of the flushing module and the flushing intensity configuration are dynamically fed back through LED indicators and the action of the solenoid valve. Specifically, the sensor sends the collected obstruction time (t) and number of times (n) at different distances (d) to the control module, which triggers the entry into the corresponding mode configuration. The control module controls the LED indicator to flash rapidly to remind the user that the corresponding configuration mode has been entered. The flashing time and number of times the LED indicator flashes can be set according to different needs.

[0039] The configuration items of the control module based on the measurement information of the laser ranging module include:

[0040] Encoding is performed using occlusion time (t) and occlusion count (n):

[0041] This includes entering the setting mode by blocking the laser sensor at a distance of d1 (1-5cm) for t1 (20s-60s) in normal mode; wherein, after the laser sensor detects that it has been blocked for more than 20s, the LED indicator will flash rapidly.

[0042] Configuration items are distinguished by the blocking time (t) (e.g., if the blocking time t = 5s, then it is the setting of flush volume).

[0043] Furthermore, the gear setting can be configured by selecting the parameter value based on the number of wave counts (n).

[0044] Different flushing modes are set to adapt to different scenarios by using different distances in front of the sensor d∈[1-5cm], occlusion time t∈[5-25s], and occlusion count n∈[1-5].

[0045] Alternatively, encoding can be performed by combining different distances in front of the sensor with the occlusion action:

[0046] This includes entering the setting mode by blocking the laser sensor at a distance of d1 (1-5cm) for t1 (20s-60s) in normal mode; wherein, after the laser sensor detects that it has been blocked for more than 20s, the LED indicator will flash rapidly.

[0047] Configuration options are differentiated by a specific distance (d) in front of the laser sensor that is obstructed (e.g., d = 5cm, which indicates the setting of the flush volume).

[0048] The gear setting is adjusted by increasing or decreasing the gear level through combinations of blocking actions (such as fast / slow swings);

[0049] Different filling modes are switched by recognizing gestures, such as waving forward and backward.

[0050] In this embodiment, the control module generates different control information for the solenoid valve drive module based on the different distances and times of obstruction received from the laser ranging module, and controls the solenoid valve drive module to perform different flushing modes, thereby realizing multiple functional modes.

[0051] Specifically, functional modes may include:

[0052] Basic functions of human body detection and automatic flushing:

[0053] When the laser sensor detects that a user has entered the sensing area (the sensing distance of the laser sensor is 1-100cm, and the user can configure the sensing distance of the laser sensor according to actual needs);

[0054] If the user stays for ≥2 seconds and the device is idle for ≥1 minute, a short flush of 0.75 seconds (the flushing time can be adjusted according to actual needs) will be performed before use.

[0055] After the pre-toilet flush, if the user stays in the room for less than 45 seconds, the urination flush mode will be activated; if the user stays in the room for more than 45 seconds, the defecation flush mode will be activated.

[0056] Water-saving modes may include:

[0057] The water-saving function can be automatically activated if the device is used more than 3 times within 5 minutes.

[0058] The water-saving mode operates by flushing for 0.5 seconds per minute (50% of the normal flushing time);

[0059] The water-saving function mode will automatically turn off if there is no use for 5 consecutive minutes.

[0060] The water-saving function mode's display feedback mechanism involves the indicator light flashing slowly, flashing quickly during rinsing, and fading out when the mode is exited.

[0061] Cleaning modes may include:

[0062] The trigger condition is that the laser sensor is blocked for 10-20 seconds in normal mode; if the laser sensor detects that it has been blocked for more than 10 seconds, the LED indicator will flash rapidly; the flashing time of the LED indicator can be set as needed.

[0063] The cleaning mode performs the following actions: turn off other functions for 5 minutes to avoid interfering with cleaning; and flush the solenoid valve once (1 second) when switching.

[0064] The cleaning mode exit condition is that cleaning is completed or the sensor is blocked for more than 5 seconds; wherein, after the laser sensor detects that the blockage time exceeds 5 seconds, the LED indicator will flash rapidly; the flashing time of the LED indicator can be set as needed;

[0065] The display feedback mechanism for cleaning mode is that the indicator light stays on while the mode is in operation and fades out when the mode is exited.

[0066] The setting modes include:

[0067] The trigger condition for setting the mode is that the sensor is blocked for 20-60 seconds, and the solenoid valve flushes water 3 times (with 1-second intervals); wherein, after the laser sensor detects that the blocking time exceeds 20 seconds, the LED indicator will flash rapidly; the flashing time of the LED indicator can be set as needed;

[0068] Sub-function configurations include:

[0069] Flushing speed setting: Enter the setting by blocking the laser sensor for 5s-10s or at a distance of 5cm-10cm, and then adjust the flushing speed and duration to 1s-5s by waving your hand 1-5 times; if the laser sensor detects that it has been blocked for more than 5s, the LED indicator will flash rapidly; the flashing time of the LED indicator can be set as needed.

[0070] Sensing distance setting: Enter the setting by blocking the laser sensor for 10-15 seconds or at a distance of 10-15cm, and then adjust the sensing distance to 40cm-80cm by waving the hand 1-4 times; if the laser sensor detects that it has been blocked for more than 10 seconds, the LED indicator will flash rapidly; the flashing time of the LED indicator can be set as needed.

[0071] Water-saving mode switch settings: Enter the setting by blocking the laser sensor for 15-20 seconds or at a distance of 15-20cm. Then, activate the water-saving mode by waving your hand once; deactivate the water-saving mode by waving your hand twice. If the laser sensor detects that it has been blocked for more than 15 seconds, the LED indicator will flash rapidly. The flashing time of the LED indicator can be set as needed.

[0072] Factory reset: To reset the factory settings, block the laser sensor for 20-25 seconds or at a distance of 20-25 cm. Then, flush twice using the solenoid valve, and the indicator light will flash rapidly to complete the factory reset. The LED indicator will flash rapidly if the laser sensor is blocked for more than 20 seconds; the flashing time of the LED indicator can be adjusted as needed.

[0073] In the sub-function configuration, real-time feedback is provided through the on / off mode of the indicator light (e.g., n flashes correspond to n levels).

[0074] This embodiment provides a specific example of setting the flushing mode of a flushing module based on a laser sensor.

[0075] For example, the first method for setting the flush volume:

[0076] The setting mode is entered when the distance d1 = 3cm for blocking the laser sensor and the time t1 = 20s for blocking the laser sensor; wherein, after the laser sensor detects that it has been blocked for more than 20s, the LED indicator will flash rapidly for 2s to indicate to the user that the setting mode has been entered.

[0077] The flush volume configuration is selected by the duration t2 = 8s when the laser sensor is blocked; if the duration of the blockage exceeds 5s, the LED indicator will flash rapidly for 2s to indicate to the user that the flush volume configuration has been entered.

[0078] Wave your hand 3 times to set the water flow to level 3 (i.e., the water flow time is 3 seconds);

[0079] The indicator light cycles from 1 second on to 0.5 seconds off, then back to 1 second on, then back to 0.5 seconds off, then back to 1 second on (matching flush speed 3).

[0080] Setup complete.

[0081] For example, the second method for setting the flush volume:

[0082] The setting mode is entered when the distance d1 = 3cm for blocking the laser sensor and the time t1 = 20s for blocking the laser sensor; wherein, after the laser sensor detects that it has been blocked for more than 20s, the LED indicator will flash rapidly for 2s to indicate to the user that the setting mode has been entered.

[0083] The laser sensor is blocked again at a distance d2 = 8cm, and the flush volume configuration is selected. After the laser sensor detects that the distance has been reached and the flush volume configuration has been entered, the LED indicator will flash rapidly for 2 seconds to indicate to the user that the flush volume configuration has been entered.

[0084] Wave your hand 3 times to set the water flow to level 3 (i.e., the water flow time is 3 seconds);

[0085] The indicator light cycles from 1 second on to 0.5 seconds off, then back to 1 second on, then back to 0.5 seconds off, then back to 1 second on (matching flush speed 3).

[0086] Setup complete.

[0087] For example, activate the water-saving mode:

[0088] When frequent use by the user triggers the water-saving mode, the system enters water-saving mode.

[0089] The indicator light flashes slowly, and the rinsing time is shortened to 0.5 seconds (normal mode is 1 second);

[0090] It will automatically exit after 5 minutes of inactivity, and the indicator light will fade out.

[0091] To perform a factory reset:

[0092] If the laser sensor is blocked at a distance d1 = 3cm for a duration t5 = 25s, a factory reset is triggered. The solenoid valve flushes twice, and the indicator light flashes twice, completing the factory reset. Specifically, if the laser sensor detects that it has been blocked for more than 25s, the LED indicator will flash rapidly to notify the user that a factory reset has been triggered.

[0093] This embodiment also provides a smart toilet, which includes a water supply pipe, a toilet body with a water tank, and the flushing module based on a laser sensor provided in this embodiment.

[0094] The flushing module is installed on the toilet body. One end of the water supply pipe is connected to the inner cavity of the toilet bowl of the toilet body, and the other end is connected to the inner cavity of the water tank, the outlet of the water pump, or the tap water pipe. The solenoid valve drive module in the flushing module is installed on the water supply pipe between the toilet bowl and the water tank, or between the toilet bowl and the water pump, or between the toilet bowl and the tap water pipe.

[0095] According to the laser sensor-based flushing module proposed in this application, different distances, times, and frequency can be detected by the laser ranging module, thereby enabling the setting of multiple flushing modes and adjustment of different water volumes. Multi-parameter configuration and intensity adjustment are achieved through the blocking action of the laser ranging sensor, making it more intelligent, allowing for precise water usage, and conserving water resources.
