Abstract
Description
Technical Field
[0001] The invention relates to the technical field of flushing control systems, in particular to a self-cleaning timed flushing control system. Background Art
[0002] There is a large flow of people in public toilets. If you use the traditional manual flushing method after using the toilet, manually operating the flush button will increase the risk of virus and bacteria transmission. When multiple people frequently touch the same button, pathogens are easily attached to its surface and spread to other people through contact. It is easy to cause cross-infection of bacteria and is very unhygienic; and traditional automatic flush toilets only use water for flushing, and the cleaning effect is poor. At the same time, the automatic induction flushing device on the traditional automatic flush toilet usually decides when to start the flushing based on the distance of the human body from the sensor range. However, if the set distance is too short, the flushing may start before the user has completely left, causing water splashing, affecting personal hygiene, so it still needs to be improved. Summary of the invention
[0003] The object of the present invention is to provide a self-cleaning timed flushing control system to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a self-cleaning timed flushing control system, comprising: a toilet pool and a flushing port, wherein a first infrared transmitter, a second infrared transmitter and an infrared receiver are arranged on one side of the top of the toilet pool, wherein the first infrared transmitter and the second infrared transmitter are used to transmit infrared signals, and the infrared receiver is used to receive infrared signals from the first infrared transmitter and the second infrared transmitter, wherein detergent boxes are arranged on both sides of the toilet pool, and a plurality of flushing ports and detergent spraying ports are arranged on both sides of the toilet pool, wherein the flushing ports and detergent spraying ports are arranged at intervals, wherein the infrared receiver further comprises a control circuit, wherein the control circuit is used to analyze the received infrared signals to determine whether a human body is approaching or moving away and to perform timing and counting, and wherein the toilet pool further comprises an execution mechanism, wherein the execution structure executes corresponding actions according to the judgment result of the control circuit.
[0005] Preferably, the control circuit includes a signal conversion module, a signal amplification module, a signal acquisition processing module and a control module, and the signal conversion module, the signal amplification module and the signal acquisition processing module are all electrically connected to the signal control module.
[0006] Preferably, the actuator includes a flush switch valve, a detergent switch valve and an alarm.
[0007] Preferably, the flushing switch valve controls the opening and closing of the flushing port, the detergent switch valve controls the opening and closing of the detergent spray port, and the alarm is used to indicate the detergent liquid level in the detergent box.
[0008] Preferably, a liquid level detector and a signal transmitter are provided in the detergent box. When the liquid level detector detects that the liquid level reaches a preset warning position, the signal transmitter transmits a signal to the control module and controls the alarm to issue an alarm prompt.
[0009] Preferably, the first infrared emitter and the second infrared emitter emit at intervals.
[0010] Preferably, the signal conversion module is used to convert the received infrared signal into a voltage signal, the signal amplification module is used to amplify the voltage signal to obtain an amplified voltage signal, and the signal acquisition and processing module is used to compare the amplified voltage signal with a preset voltage threshold. When the amplified voltage signal is greater than or equal to the preset voltage threshold, it is judged that the human body is approaching; when the amplified voltage signal is less than the preset voltage threshold, it is judged that the human body is far away.
[0011] Preferably, the control module is electrically connected to a timer and a counter.
[0012] Preferably, the water outlet direction of the flushing port is arranged obliquely downward, and the liquid outlet direction of the detergent spray port is arranged obliquely upward.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes that when the self-cleaning timed flushing control system is used, the first infrared transmitter transmits a first group of infrared light, the infrared receiver receives the infrared light emitted by the first infrared reflector and processes it through the control circuit to determine whether there is someone approaching the toilet pool. If no one is approaching, the second infrared transmitter transmits a second group of infrared light, the infrared receiver receives the infrared light emitted by the second infrared transmitter and processes it through the control circuit to determine whether there is someone approaching the toilet pool. If no one is approaching, the first infrared transmitter transmits infrared light again, and this process is repeated. If the first infrared light emitted by the first infrared emitter determines that someone is approaching the toilet pool, it will continue to determine whether the person in front of the toilet pool has left. If not, it will continue to determine whether someone is approaching the toilet pool. If the person in front of the toilet pool has left, the timer will start counting down and control the detergent switch valve to open to spray the detergent. When the detergent is sprayed, the signal emitted by the liquid level detector and the signal transmitter is used to determine whether the detergent is insufficient. If the detergent is insufficient, the flush switch valve is controlled to open for flushing and the alarm is activated at the same time. If the detergent is sufficient, the counter counts once after the timer countdown ends. After counting, it is determined whether the counter value reaches the preset value. If it does not reach the preset value, the flush switch valve is controlled to open for flushing. If it reaches the preset value, the flush switch valve and the detergent switch valve are controlled to open at the same time, and flushing and detergent are sprayed at the same time, and the counter is reset to zero and the counting starts again.
[0015] The entire flushing control system is reasonably designed and easy to use. It can automatically spray detergent and use detergent and water to self-clean the toilet pool, improving the cleanliness of the toilet pool. At the same time, through repeated confirmation by the first infrared emitter and the second infrared reflector, it can start the flushing process after confirming that no one is there, avoiding the problem of water splashing caused by premature start. It effectively solves the problems existing in traditional public toilets, not only improving sanitary conditions, but also enhancing the user experience.

If the first group of infrared light emitted by the first infrared transmitter 3 is processed to determine that someone is approaching the toilet pool, it will continue to determine whether the person in front of the toilet pool has left, and if not, it will continue to determine whether someone is approaching the toilet pool, and if the person in front of the toilet pool has left, the timer starts to count down and controls the detergent switch valve to open to spray the detergent.
[0021] The control circuit includes a signal conversion module, a signal amplification module, a signal acquisition processing module and a control module, and the signal conversion module, the signal amplification module and the signal acquisition processing module are all electrically connected to the signal control module. The signal conversion module is used to convert the received infrared signal into a voltage signal, the signal amplification module is used to amplify the voltage signal to obtain an amplified voltage signal, and the signal acquisition processing module is used to compare the amplified voltage signal with a preset voltage threshold. When the amplified voltage signal is greater than or equal to the preset voltage threshold, it is judged that the human body is approaching, and when the amplified voltage signal is less than the preset voltage threshold, it is judged that the human body is far away. The control module is electrically connected with a timer and a counter.
[0022] The first infrared transmitter 3 and the second infrared transmitter 4 transmit at intervals. The first infrared transmitter 3 transmits a first group of infrared light, the infrared receiver 7 receives the infrared light emitted by the first infrared reflector 3 and processes it through the control circuit to determine whether there is anyone approaching the toilet pool. If no one is approaching, the second infrared transmitter 4 transmits a second group of infrared light, the infrared receiver 7 receives the infrared light emitted by the second infrared transmitter and processes it through the control circuit to determine whether there is anyone approaching the toilet pool. If no one is approaching, the first infrared transmitter transmits infrared light again, and so on repeatedly;
[0023] The actuator includes a flushing switch valve, a detergent switch valve and an alarm. The flushing switch valve controls the opening and closing of the flushing port 5, the detergent switch valve controls the opening and closing of the detergent spray port 6, and the alarm is used to indicate the detergent liquid level in the detergent box.
[0024] A liquid level detector and a signal transmitter are provided in the detergent box 2. When the liquid level detector detects that the liquid level reaches the preset warning position, the signal transmitter transmits a signal to the control module and controls the alarm to give an alarm prompt. When the detergent is sprayed, the signal transmitted by the liquid level detector and the signal transmitter is used to determine whether the detergent is insufficient. If the detergent is insufficient, the flushing switch valve is controlled to open for flushing and the alarm is made to give an alarm prompt.

[0026] The present invention realizes that when the self-cleaning timed flushing control system is used, the first infrared transmitter 3 transmits a first group of infrared light, the infrared receiver 7 receives the infrared light emitted by the first infrared reflector 3 and processes it through the control circuit to determine whether there is someone approaching the toilet pool. If no one is approaching, the second infrared transmitter 4 transmits a second group of infrared light, the infrared receiver 7 receives the infrared light emitted by the second infrared transmitter and processes it through the control circuit to determine whether there is someone approaching the toilet pool. If no one is approaching, the first infrared transmitter transmits infrared light again, and this process is repeated. If the first infrared light emitted by the first infrared emitter 3 determines that someone is approaching the toilet pool, it will continue to determine whether the person in front of the toilet pool has left. If the person has not left, it will continue to determine whether someone is approaching the toilet pool. If the person in front of the toilet pool has left, the timer will start counting down and control the detergent switch valve to open to spray the detergent. When the detergent is sprayed, the signal emitted by the liquid level detector and the signal transmitter is used to determine whether the detergent is insufficient. If the detergent is insufficient, the flush switch valve is controlled to open for flushing and the alarm is activated at the same time. If the detergent is sufficient, the counter counts once after the timer countdown ends. After counting, it is determined whether the counter value reaches the preset value. If it does not reach the preset value, the flush switch valve is controlled to open for flushing. If it reaches the preset value, the flush switch valve and the detergent switch valve are controlled to open at the same time, and flushing and detergent are sprayed at the same time, and the counter is reset to zero and the counting starts again.
[0027] The entire flushing control system is reasonably designed and easy to use.

This effectively solves the problems existing in traditional public toilets, not only improving sanitary conditions, but also enhancing the user experience.
