[0066] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0067] like Figures 1-2 As shown, the present invention provides a smart toilet based on hand and foot dual sensing, including a smart toilet body 1, a seat module 13, an upper cover module 12, a cleaning module 6, a drying module 11, a flushing module 10, a seat detection module 7, a first hand sensing module 2, a second hand sensing module 3, a kicking sensing module 4, a control module 14 and a power module 5, wherein the power module 5 is used to supply power to the smart toilet, and the first hand sensing module 2, the second hand sensing module 3, the kicking sensing module 4, the seat module 13, the upper cover module 12, the cleaning module 6, the drying module 11 and the flushing module 10 are all Electrically connected to the control module 14; the first hand sensing module 2 is used to obtain a first hand sensing signal, the second hand sensing module 3 is used to obtain a second hand sensing signal, the kick sensing module 4 is used to obtain a kick sensing signal, and the seat detection module 7 is arranged in the seat module 13 and is used to detect the seat signal on the seat module 13; the control module 14 is used to control the switch states of the seat module 13, the upper cover module 12, the cleaning module 6, the drying module 11 and the flushing module 10 according to the kick sensing signal, the seat signal, the first hand sensing signal and the second hand sensing signal.

[0068] It should be noted that the control module is a single-chip microcomputer, which integrates many components such as an arithmetic unit, a controller, a memory, and an input / output device to realize many functions such as signal processing and data storage. For example, the arithmetic unit includes a large number of comparison circuits, which can perform logical operations on the received signal instructions. Preferably, the models of the above-mentioned single-chip microcomputer include but are not limited to PIC16F18323.

[0069] The present invention obtains the first hand sensing signal through the first hand sensing module 2, obtains the second hand sensing signal through the second hand sensing module 3, obtains the kick sensing signal through the kick sensing module 4, detects the seat signal on the seat module 13 through the seat detection module 7, and controls the switch states of the seat module 13, the upper cover module 12, the cleaning module 6, the drying module 11 and the flushing module 10 through the control module 14 according to the kick sensing signal, the seat signal, the first hand sensing signal and the second hand sensing signal. The present invention controls the switch states of various functional modules of the smart toilet by means of hand and foot dual sensing, without direct contact and without opening additional installation holes, and can solve the problems of difficult hygienic cleaning of smart toilets, the need for additional holes and high costs.

[0070] Specifically, the kick sensing module 4 is attached to the inner side of the bottom of the ceramic for foot sensing, and the first hand sensing signal and the second hand sensing module 3 are attached to the upper back side of the ceramic for hand sensing. Note: Short sensing means the sensing time is less than 1 second; long sensing means the sensing time is greater than 1 second.

[0071] Before seat sensing (i.e., the seat detection module 7 has not detected a seat signal), foot sensing is valid and hand sensing is invalid: ① Short sensing: When the foot approaches the area of ​​the foot kick sensing module 4, a short sensing occurs, and the smart toilet automatically opens the upper cover. When it approaches the short sensing again, the seat ring is opened. When it approaches the short sensing again, the seat ring is closed. When it approaches the short sensing and the upper cover again, the toilet flushes; the cycle continues; ② Long sensing: When the upper cover and the seat ring are both closed, the foot approaches the area of ​​the foot kick sensing module 4 for a long sensing, and the smart toilet automatically opens the upper cover and the seat ring; when the upper cover is opened and the seat ring is closed, the foot approaches the area of ​​the foot kick sensing module 4 for a long sensing, and the smart toilet automatically closes the upper cover and flushes; when the upper cover and the seat ring are both open, the foot approaches the foot kick sensing module 4 for a long sensing, and the smart toilet automatically closes the upper cover and the seat ring and flushes.

[0072] After the seat sensing (that is, the seat detection module 7 does not detect the seat signal), the foot sensing is invalid and the hand sensing is valid: ① Short sensing: When the hand is close to the first hand sensing module 2 area, the short sensing occurs, and the smart toilet stops the arm washing, women's washing and drying functions; when the hand is close to the second hand sensing module 3 area, the short sensing occurs, and the smart toilet starts the arm washing function; ② Long sensing: When the hand is close to the first hand sensing module 2 area, the long sensing occurs, and the smart toilet starts the drying function; when the hand is close to the second hand sensing module 3 area, the long sensing occurs, and the smart toilet starts the women's washing function; ③ Waving sensing: When a person waves his hand from the first hand sensing module 2 area to the second hand sensing module 3 area or from the second hand sensing module 3 area to the first hand sensing module 2 area, the smart toilet starts the flushing function.

In addition, the distance between the first hand sensing module 2 and the second hand sensing module 3 is 5 to 10 cm, but is not limited thereto; if the distance is too small, false triggering will occur (that is, when the user triggers the first hand sensing module 2 with his hand, the second hand sensing module is also triggered) and the sensing error or failure will occur; if the distance is too large, it is inconvenient for the user to perform hand sensing, such as waving sensing (that is, when a person waves from the first hand sensing module 2 area to the second hand sensing module 3 area or from the second hand sensing module 3 area to the first hand sensing module 2 area).

[0075] Furthermore, the first hand sensing module 2, the second hand sensing module 3 and the kick sensing module 4 all include a signal acquisition unit 21 and a signal processing unit 22, the signal acquisition unit 21 is attached to the inner wall of the smart toilet body 1 and is electrically connected to the signal processing unit 22, and the signal processing unit 22 is also electrically connected to the control module 14 and the power module 5.

[0082] It should be noted that, in this embodiment, the power adapter is used to access the mains, but is not limited to this; when the mains is disconnected, the power adapter has no output, the second switch tube is turned on, and the various functional modules are powered by the rechargeable battery and the voltage stabilizing unit; when the mains is normal, the power adapter has an output, the second switch tube is turned off, and the various functional modules are powered by the power adapter and the voltage stabilizing unit.

[0095] S201, determining whether the sensing duration of the kick sensing signal is less than a first preset duration;

[0096] S202, when the judgment is yes, it is a short kick sensing mode. Each time the short kick sensing mode is triggered, the upper cover module is opened, the seat module is opened, the seat module is closed, or the upper cover is closed and the flushing module is opened at the same time.

[0097] S203, when the judgment is no, it is a long kick sensing mode, wherein:

[0098] When it is detected that both the upper cover module and the seat module are closed, if the kicking sensing mode is triggered, the upper cover module and the seat module will be opened at the same time.

[0099] When it is detected that the upper cover module is open and the seat module is closed, if the kicking sensing mode is triggered, the upper cover module will be closed and the flushing module will be opened at the same time.

[0100] When it is detected that both the upper cover module and the seat module are open, if the long kick sensing mode is triggered at this time, the seat module and the upper cover module will be closed and the flush module will be opened at the same time.

[0101] It should be noted that short induction means that the induction time is less than 1 second; long induction means that the induction time is greater than 1 second.

[0102] Before seat sensing (i.e., the seat detection module 7 has not detected a seat signal), foot sensing is valid and hand sensing is invalid: ① Short sensing: When the foot approaches the area of ​​the foot kick sensing module 4, a short sensing occurs, and the smart toilet automatically opens the upper cover. When it approaches the short sensing again, the seat ring is opened. When it approaches the short sensing again, the seat ring is closed. When it approaches the short sensing and the upper cover again, the toilet flushes; the cycle continues; ② Long sensing: When the upper cover and the seat ring are both closed, the foot approaches the area of ​​the foot kick sensing module 4 for a long sensing, and the smart toilet automatically opens the upper cover and the seat ring; when the upper cover is opened and the seat ring is closed, the foot approaches the area of ​​the foot kick sensing module 4 for a long sensing, and the smart toilet automatically closes the upper cover and flushes; when the upper cover and the seat ring are both open, the foot approaches the foot kick sensing module 4 for a long sensing, and the smart toilet automatically closes the upper cover and the seat ring and flushes.

[0103] like Fig.13 As shown, preferably, the steps of acquiring a first hand sensing signal through the first hand sensing module, acquiring a second hand sensing signal through the second hand sensing module, and executing the hand sensing control mode according to the first hand sensing signal and the second hand sensing signal include:

[0104] S301, comparing the sensing durations of the first hand sensing signal and the second hand sensing signal with second preset durations respectively;

[0105] S302, when only the first hand sensing signal is obtained and its sensing duration is less than the second preset duration, it is the first hand short sensing mode: the hip washing unit, the feminine washing unit and the drying module are turned off,

[0106] When only the first hand sensing signal is obtained and its sensing duration is not less than the second preset duration, it is the first hand length sensing mode: the drying module is turned on,

[0107] When only the second hand sensing signal is obtained and its sensing duration is less than the second preset duration, it is the second hand short sensing mode: the hip washing unit is turned on,

[0108] When only the second hand sensing signal is obtained and its sensing duration is not less than the second preset duration, it is the second hand length sensing mode: the feminine washing unit is turned on,

[0109] When the first hand sensing signal and the second hand sensing signal are obtained, it is the hand waving sensing mode: the flushing module is turned on.

[0110] It should be noted that short induction means that the induction time is less than 1 second; long induction means that the induction time is greater than 1 second.

[0111] After the seat sensing (that is, the seat detection module 7 does not detect the seat signal), the foot sensing is invalid and the hand sensing is valid: ① Short sensing: When the hand is close to the first hand sensing module 2 area, the short sensing occurs, and the smart toilet stops the arm washing, women's washing and drying functions; when the hand is close to the second hand sensing module 3 area, the short sensing occurs, and the smart toilet starts the arm washing function; ② Long sensing: When the hand is close to the first hand sensing module 2 area, the long sensing occurs, and the smart toilet starts the drying function; when the hand is close to the second hand sensing module 3 area, the long sensing occurs, and the smart toilet starts the women's washing function; ③ Waving sensing: When a person waves his hand from the first hand sensing module 2 area to the second hand sensing module 3 area or from the second hand sensing module 3 area to the first hand sensing module 2 area, the smart toilet starts the flushing function.

[0112] like Fig.14 As shown, preferably, the control method of the smart toilet based on hand and foot dual sensing also includes:

[0113] S401, obtaining a seating signal from a seat ring module through a seating detection module, and determining whether a person is seated on the seat ring module according to the seating signal,

[0114] S402: If the result is yes, the odor detection module is turned on and S404 is executed.

[0115] S403, when the judgment is no, the odor detection module is not turned on;

[0116] S404, detecting the odor signal of the smart toilet by using an odor detection module, and determining whether the odor signal is greater than a preset odor signal,

[0117] S405: If the answer is yes, the flushing module is turned on.

[0118] S406: When the judgment is no, the flushing module is not turned on.

[0119] It should be noted that, in this embodiment, the odor signal of the smart toilet is detected by the odor detection module 16, and the switch state of the flush module 10 is controlled by the control module 14 according to the odor signal and the seat signal; during the toilet process, if the odor signal detected by the odor detection module is greater than the preset value, it means that the odor is very strong. At this time, if the user's seat signal is detected, the flush module is controlled to flush. If the user's seat signal is not detected at this time, the flush is not flushed. It should be emphasized that the switch state of the flush module can be controlled not according to the presence or absence of the seat signal, but only according to the size of the odor value.

[0120] Furthermore, the control method of the smart toilet based on hand and foot dual sensing also includes:

[0121] S501, detect whether the mains power is supplied normally through the power supply switch unit,

[0122] S502, when it is detected that the mains power is normally supplied, the mains power supplies power to the smart toilet through the power adapter, otherwise the smart toilet is powered by the rechargeable battery, wherein the power module includes a power adapter, a rechargeable battery, a charging switch unit, a power detection unit, a power switch unit and a voltage stabilizing unit;

[0123] S503, detecting the remaining power of the rechargeable battery by the power detection unit, and determining whether the remaining power is less than a preset power.

[0124] S504: If the judgment is yes, the charging switch unit is turned on, and the city power charges the rechargeable battery through the power adapter.

[0125] S505: When the judgment is no, the charging switch unit is not turned on.

[0126] It should be noted that, in this embodiment, the power adapter is used to access the mains, but is not limited to this; when the mains is disconnected, the power adapter has no output, the second switch tube is turned on, and the various functional modules are powered by the rechargeable battery and the voltage stabilizing unit; when the mains is normal, the power adapter has output, the second switch tube is turned off, and the various functional modules are powered by the power adapter and the voltage stabilizing unit. With this embodiment, the normal use of the smart toilet can be guaranteed in the event of a power outage. In this embodiment, the voltage detection component 541 can also detect the voltage value of the rechargeable battery in real time to obtain the remaining power of the rechargeable battery. When the remaining power is less than the preset power, the first switch tube is turned on, and the power adapter charges the rechargeable battery; in addition, when the power of the rechargeable battery is below the preset power for a long time, the low power reminder component 542 performs a low power alarm to remind the user to charge or replace the battery at the right time.

[0127] More preferably, the control method of the smart toilet based on hand and foot dual sensing also includes:

[0128] S601, obtaining a seating signal from a seat ring module through the seating detection module, and determining whether a person is sitting on the seat ring module according to the seating signal,

[0129] S602: If the result is yes, the heating unit is turned on to heat the seat ring module, and step S304 is executed.

[0130] S603, when the judgment is no, the heating unit is not turned on, wherein the seat ring module is provided with a seat ring heating module, and the seat ring heating module includes a heating unit, a heat transfer unit and a temperature detection unit;

[0131] S604, obtaining an identity signal of the seated user through an identity recognition module, and determining whether the identity signal is bound to a preset heating temperature.

[0132] S605, when the judgment is yes, the on / off state of the heating unit is controlled according to the preset heating temperature, and when the temperature signal detected by the temperature detection unit is greater than the preset heating temperature, the heating unit is turned off.

[0133] S606, when the judgment is no, the on / off state of the heating unit is controlled according to the default heating temperature, and when the temperature signal detected by the temperature detection unit is greater than the default heating temperature, the heating unit is turned off.

[0134] It should be noted that, in this embodiment, the seating signal on the seat module is first obtained by the seating detection module, and it is determined whether someone is sitting on the seat module according to the seating signal. When the seating signal is detected, the low-temperature heating function of the seat is turned on; then the temperature signal of the seat module 13 is detected by the temperature detection unit 93, and the switch state of the heating unit 91 is controlled by the control module 14 according to the temperature signal. In this embodiment, the identity signal of the user is also identified by the identity recognition module 15, and the switch state of the heating unit 91 is controlled by the control module 14 according to the identity signal and the seating signal; in this embodiment, the identity signal of the user and the corresponding seat heating temperature are stored in the identity recognition module 15 in advance. When the user uses this product, the identity signal of the user is first identified by the identity recognition module, so that the seat is heated according to the corresponding seat heating temperature; if the identity signal of the user does not exist in the identity recognition module (that is, the user has not entered the identity signal into the identity recognition module in advance), the seat is heated according to the default seat heating temperature.

These improvements and modifications are also considered to be within the scope of protection of the present invention.
