Description

Intelligent flushing device

Technical Field

The utility model relates to a toilet flushing device and a control method thereof, in particular to an automatic flushing device for toilets, which is especially suitable for open-mounted or hidden automatic flushing tanks, automatic flushing valves and the like.

Background

Along with the improvement of the living standard of Chinese people and the attention and the strong support of all levels of government leaders, the toilet revolution is promoted, the automatic flushing tank in the toilet and the toilet is suitable for all families, is particularly suitable for parents with the age and pregnant women with inconvenient actions, has small strength, and can cut off the propagation path of bacteria and viruses while the people feel the convenience of the automatic intelligent flushing device according to the child who does not operate the manual flushing tank in recent years from SARS to new crown epidemic situation, so the automatic flushing tank is deeply valued by the government and is favored by common people.

At present, the automatic flushing device for the toilet mainly comprises three types:

the defects of the common infrared induction flushing device are mainly shown as follows: the common infrared induction flushing device receives and amplifies reflected light according to a light reflection principle, and simply processes the reflected infrared according to the intensity of the received infrared, and the reflected infrared is weakened and converted into an approximate distance, so that the distance between a person and the flushing device is deduced, and corresponding flushing processing is carried out. Because the intensity of the received light is greatly influenced by the color of a reflecting object such as a wall or clothes worn by people, the size of a reflecting surface and the like, the deviation of the received light converted into a distance is very large, the light cannot normally work, and no water is flushed when water is required or water is flushed for multiple times when the water is not required;

a water flushing device with ultrasonic induction is prepared, and the main deficiency is as follows: the problem of the blind zone of the ultrasonic wave is solved, and the misjudgment is caused by the large difference of the reflection capacities of different objects to the ultrasonic wave; thirdly, the ultrasonic wave can be reflected for many times in closed spaces such as a toilet and the like, so that the false disconnection and the false flushing are caused; fourthly, the larger the angle between the reflecting surface and the ultrasonic transmitting surface is, the more the reflected signal is lost (the same as the reflected signal cannot be detected by an invisible warplane), so that the false flushing is caused;

the microwave radar induction flushing device has the following main defects: firstly, the detection distance is greatly influenced by the surrounding environment such as obstacles, temperature, humidity and the like, so that misjudgment and misflushing are caused, and secondly, a closely-spaced static object such as a human body is not clearly separated from a wall body close to the human body, so that the work is not frequent;

some of the existing induction products are punched on a water tank for installation, are difficult to process, are easy to break the whole tank body, and some induction products are directly designed on the products, so that the induction products are complex in structure, single in style, complex in production and installation and high in processing cost.

The intelligent flushing device of the utility model has the following working process:

firstly, connecting and electrifying a battery box, a driving controller module and a detection device;

secondly, the MCU in the controller module is initialized firstly, then a self-checking program is run, whether the input and output states, voltage and the like of the peripheral equipment of the central processing unit are normal or not is checked, abnormal reasons can be prompted by voice normally, the processing is waited, the automatic flushing is carried out once after the normal operation is determined, and products with voice functions can be provided with corresponding explanation prompting voices;

thirdly, prompting the items needing attention for automatic debugging of the toilet;

fourthly, after delaying for 20 seconds, starting to detect whether sundries and the like exist in the front 50 centimeters of the intelligent sensor;

fifthly, if the data exists, prompting a constructor to remove the data, if the data does not exist, counting the value of the accurate distance S0 from the wall right in front of the sensor or the door of the toilet to the detection device 4, and storing the average data S0; assuming that the maximum distance from the chest to the back of the human body is SM, the distance SG detected by the detection device 4 in normal operation is as follows: calculating to obtain a reference distance for judging whether a person is in the toilet or not as SW by using a formula SW equal to S0-SM/2, and if SM is equal to 0.17 m, calculating to obtain: SW is S0-0.85 m and is stored in the MCU;

sixthly, if the actually measured distance SG is larger than 1.50 m, taking S0 as 1.40 m; if the detected distance SG is less than 1.50 meters, taking S0 as SG; at this time, the S0 detection value taking program is finished, and the voice prompts the user that the user can use the device normally;

seventh step, explanation: the maximum distance from the chest to the back of the human body is SM which is 0.17 m; when the back of the human body is tightly attached to a wall or a door and the human body goes to a toilet, the distance SG from the chest plane of the human body to the induction probe module 43 is S0-SM; the value SW is S0-SM/2; then there are:

when someone uses, then have: s0> SW > SG;

when the device is not used, the following steps are provided: s0> -SG > SW;

when the actual detection distance SG < SW, judging that the user is in a using state;

when the actual detection distance SG is greater than SW, judging that the vehicle is in an unmanned use state;

eighthly, according to the rule of the seventh step, the MCU intermittently and actually measures data SG of the distance between the object in front of the induction probe module 43 and the induction probe module 43, if SG is greater than SW, the toilet is judged to be used by no person, and meanwhile, timing is carried out, and if the unmanned time reaches the preset time T1, a sleep power-saving program is carried out.

The ninth step: if the power-saving program detects that SG < SW, the power-saving program is stopped, and the using time of someone is counted as T2;

the tenth step: when the timing time does not reach the preset minimum time T3 judged to be normally used by people, clearing the T2; if the preset minimum time T3 for judging normal use is reached, whether the user leaves is detected, namely whether SG is larger than SW is detected;

as a tenth step, if SG > SW is detected, timing is started to be T4, and if T4 reaches the preset time T5, water is flushed in a preset proportion according to the use time T2 recorded above, that is: the minimum amount of half-tank water is about 3 liters, the more time is used, the equal proportion of the flushing time is increased, but the maximum amount of one-tank water is controlled to be about 6 liters;

and step ten, after the flushing is finished, clearing the temporary data T2, T4 and SG, judging whether a person uses the toilet again, and entering the next program cycle.

Referring to fig. 8, it can be seen that if someone uses the toilet, the detected data can be analyzed.

The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention as claimed.
