Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bathrooms, in particular to a flush toilet with an aromatherapy function. Background Art
[0002] Traditional flush toilets generally only have basic flushing and cleaning functions and cannot provide fragrance to remove odors in public areas such as bathrooms. Therefore, aromatherapy machines that are independently installed in bathrooms have emerged. However, these independently installed aromatherapy machines cannot spray fragrance liquid in conjunction with the frequency of use of the flush toilet, resulting in the fragrance liquid being too strong or too weak, affecting the user experience. Utility Model Content
[0003] In order to overcome the defects of the prior art, the utility model provides a flush toilet with an aromatherapy function to solve the above problems.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a flush toilet with aromatherapy function, comprising an MCU, a button trigger module and an aromatherapy atomization trigger module;
[0005] The output end of the key trigger module is provided with a key switch, which is connected to the toilet flush switch to drive the key switch to close or open through the toilet flush switch. The output end of the key trigger module is electrically connected to the signal input terminal PC1 of the MCU;
[0006] The input end of the aromatherapy atomization trigger module is electrically connected to the signal output end PWM of the MCU, and the output end of the aromatherapy atomization trigger module is electrically connected to an atomizer sheet.
[0007] It is worth noting that the aromatherapy atomization trigger module includes an N-channel field effect transistor Q1 and a three-pin inductor L1. The signal output terminal PWM of the MCU is electrically connected to the G pole of the N-channel field effect transistor Q1, the S pole of the N-channel field effect transistor Q1 is grounded, and the D pole of the N-channel field effect transistor Q1 is electrically connected to the metal surface of the atomizer and the first end pin of the three-pin inductor L1 respectively. The second end pin of the three-pin inductor L1 is electrically connected to the power supply, and the third end pin of the three-pin inductor L1 is electrically connected to the ceramic surface of the atomizer.
[0008] Preferably, the aromatherapy atomization trigger module also includes a resistor R4, a resistor R9 and a capacitor C7, the S pole of the N-channel field effect transistor Q1 is electrically connected to the first end of the resistor R9 and the first end of the resistor R4, respectively, the second end of the resistor R9 is grounded, the second end of the resistor R4 is electrically connected to the first end of the capacitor C7 and the current feedback input terminal PA3 of the MCU, and the second end of the capacitor C7 is grounded.

[0010] Specifically, the power supply includes a battery pack and a voltage regulator U1. The positive pole of the battery pack is electrically connected to the input end of the voltage regulator U1. The positive pole of the battery pack forms a 6V voltage output port of the power supply. The negative pole of the battery pack and the ground end of the voltage regulator U1 are both grounded. The output end of the voltage regulator U1 forms a 4V voltage output port of the power supply.
[0011] It is worth noting that it also includes a warning light module, which includes multiple LED lights. The positive poles of the LED lights are electrically connected to the power supply, and the negative poles of the LED lights are electrically connected to the low-level output end of the MCU.
[0012] The beneficial effect of the present utility model is that: in the flush toilet with aromatherapy function, the push switch is driven by the toilet flush switch, so that the push switch will be activated and closed only after the toilet flush switch is pressed, so that the MCU generates a PWM signal and drives the atomizer to work. When the toilet flush switch does not work, the push switch will not work either, and the atomizer will not work either. In this way, the atomizer will start working only after the toilet flush switch is activated, thereby removing odors from public areas such as toilets, using aromatherapy reasonably, and avoiding too much or too concentrated aromatherapy liquid that makes people feel disgusted, or too little aromatherapy liquid that causes poor odor removal effect, thereby improving the user experience.

[0018] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.
[0019] like Figure 1-5 As shown, a flush toilet with aromatherapy function includes an MCU, a button trigger module and an aromatherapy atomization trigger module;
[0020] The output end of the key trigger module is provided with a key switch, which is connected to the toilet flush switch so as to drive the key switch to close or open via the toilet flush switch. The output end of the key trigger module is electrically connected to the signal input terminal PC1 of the MCU. In this embodiment, the key switch and the toilet flush switch are physically connected so that the movable portion of the key switch is connected to the movable portion of the toilet flush switch, so that the movable portion of the key switch can follow the movement of the movable portion of the toilet flush switch.
[0021] The input terminal of the aromatherapy atomization trigger module is electrically connected to the signal output terminal PWM of the MCU, and the output terminal of the aromatherapy atomization trigger module is electrically connected to the atomizer. In this embodiment, the aromatherapy liquid is soaked in the cotton swab and contacts the atomizer. The atomizer, upon receiving power, begins to vibrate at high speed, thereby atomizing the aromatherapy liquid.
[0022] In the flush toilet with aromatherapy function, the push switch is driven by the toilet flush switch, so that the push switch will be activated and closed only after the toilet flush switch is pressed, so that the MCU generates a PWM signal and drives the atomizer to work. When the toilet flush switch does not work, the push switch will not work either, and the atomizer will not work either. In this way, the atomizer will start working only after the toilet flush switch is activated, thereby removing odors from public areas such as toilets and using aromatherapy reasonably to avoid excessive and concentrated aromatherapy liquid that makes people feel disgusted or too little that causes poor odor removal effect, thereby improving the user experience.
[0023] It is worth noting that if Figure 1As shown, the aromatherapy atomization trigger module includes an N-channel FET Q1 and a three-pin inductor L1. The MCU's signal output PWM is electrically connected to the G terminal of the N-channel FET Q1. The S terminal of the N-channel FET Q1 is grounded. The D terminal of the N-channel FET Q1 is electrically connected to the metal surface of the atomizer and the first end of the three-pin inductor L1, respectively. The second end of the three-pin inductor L1 is electrically connected to the power supply, and the third end of the three-pin inductor L1 is electrically connected to the ceramic surface of the atomizer. After detecting the key switch press signal, the MCU automatically wakes up and outputs a 108KHz PWM wave to control the high-speed switching of the N-channel FET Q1, thereby controlling the high-speed vibration of the atomizer, atomizing the aromatherapy liquid in the cotton swab and spraying it into the air. The model of the three-pin inductor L1 is CD75-30.
[0024] Preferably, Figure 1 As shown, the aromatherapy atomization trigger module also includes a resistor R4, a resistor R9 and a capacitor C7. The S pole of the N-channel field effect transistor Q1 is electrically connected to the first end of the resistor R9 and the first end of the resistor R4, respectively. The second end of the resistor R9 is electrically connected to the first end of the capacitor C7 and the current feedback input terminal PA3 of the MCU, respectively. The second end of the capacitor C7 is grounded. The resistor R4 and the resistor R9 form a current sampling detection circuit. The working current of the atomizer is converted into a voltage signal through the resistor R9. After RC filtering through the resistor R4 and the resistor C7, it is input to the MCU for ADC analog-to-digital conversion. The MCU detects the working current of the atomizer in real time through the current sampling detection circuit. If the aromatherapy liquid is insufficient, the working current of the atomizer will be less than or greater than the set threshold. At this time, the MCU immediately turns off the PWM output to stop the atomizer from working, preventing the atomizer from "dry burning" and burning.
[0025] Specifically, if Figure 3 As shown, the key trigger module includes resistors R6 and R10. The first end of the resistor R6 is electrically connected to the power supply, and the second end of the resistor R6 is electrically connected to the first end of the resistor R10 and the signal input terminal PC1 of the MCU respectively. The second end of the resistor R10 is electrically connected to the first end of the key switch, and the second end of the key switch is grounded. When the key switch is not pressed, the signal input terminal PC1 of the MCU is high, and the MCU and the entire system are in a standby sleep state with low power consumption. The standby power consumption current is less than 4uA. After the key switch is pressed, the signal input terminal PC1 of the MCU is low, thereby triggering the MCU to start working and driving the atomizer to work.
[0026] Optional, such as Figure 4As shown, the power supply includes a battery pack and a voltage regulator U1. The positive electrode of the battery pack is electrically connected to the input terminal of the voltage regulator U1. The positive electrode of the battery pack forms the 6V voltage output port of the power supply. The negative electrode of the battery pack and the ground terminal of the voltage regulator U1 are both grounded. The output terminal of the voltage regulator U1 forms the 4V voltage output port of the power supply. In this embodiment, the 6V voltage output port of the power supply is electrically connected to the second end of the three-pin inductor L1, and the 4V voltage output port of the power supply is electrically connected to the first end of the resistor R6, the power input terminal VDD of the MCU, and the positive electrode of the LED lamp.
[0027] It is worth noting that if Figure 5 As shown, it also includes a warning light module, which includes multiple LED lights. The positive poles of the LED lights are electrically connected to the power supply, and the negative poles of the LED lights are electrically connected to the low-level output terminal of the MCU. In this embodiment, the low-level output terminal of the MCU outputs a low level to activate the LED lights to emit light, thereby serving as a warning. In this embodiment, when the system is operating normally, LED1-LED4 light up in sequence, then all light up and then go out; when the operating current of the atomizer is abnormal, LED1-LED4 flash simultaneously to indicate an alarm.
[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
