Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 3, the present embodiment provides an intelligent disinfection toilet lid, which includes a toilet lid body 1, a display screen 2, a VOC sensor 3, a control chip 4, a disinfection device 5 and a closed sensor 6. The display screen 2 is arranged at the center of the outer side surface of the toilet lid body 1. The closed sensor 6, the VOC sensor 3 and the sterilizing device 5 are all arranged on the inner side surface of the toilet cover body 1. The display screen 2, the VOC sensor 3, the closed inductor 6 and the disinfection device 5 are all connected with the control chip 4. The control chip 4 can be a commercially available microprocessor or a single chip microcomputer, and is embedded in the toilet lid body 1 to form an embedded system. The embedded system is changed to realize the detection of the open-close state and the VOC concentration of the toilet lid through the closed inductor 6 and the VOC sensor 3, so that the starting time of the sterilizing device 5 is controlled, and meanwhile, the display screen 2 is used for displaying the sterilizing state.

The closing sensor 6 is used to monitor the open or closed state of the toilet lid body 1. The closed sensor 6 may be an infrared sensor or a pressure sensor, in this embodiment, an infrared sensor is used, and the presence or absence of the object is detected by using the light shielding or reflection of the detected object to the infrared beam and gating of the synchronous loop. And when the distance between the toilet cover and the toilet is smaller than a preset value, triggering the infrared sensor.

The VOC sensor 3 is used to monitor the concentration of organic volatiles in the toilet. The principle of the VOC sensor 3 is: when the noble metal oxide in the sensor meets VOC gas such as methane, ammonia gas and the like, the resistance value of the noble metal oxide changes, so that the detection work of the VOC gas is realized.

The disinfection device 5 can generally adopt an ultraviolet lamp or a disinfection solution spraying device, and in the embodiment, a commercially available ultraviolet lamp is adopted. The ultraviolet lamp is started under the control of the control chip 4, and the mycoprotein is photolyzed and denatured by the ultraviolet irradiation, so that the amino acid, nucleic acid and enzyme of the thallus are destroyed and die. Meanwhile, when the ultraviolet rays pass through the air, oxygen in the air is ionized to generate ozone, the sterilization effect is enhanced, and the ozone generator has an accelerated volatilization effect on organic volatile matters such as methane, ammonia gas and the like generated by excretion.

The display screen 2 adopts an OLED screen to display the disinfection state in real time. The main features of an OLED, which is an electroluminescent device using a multilayer organic thin film structure, are that it is easy to fabricate and requires low driving voltage, which makes the OLED well applicable to a toilet lid for highlighting. When the VOC sensor 3 or the disinfection device 5 is in a working state, the display screen 2 can display text or graphic contents to remind a user. In this embodiment, text reminding is employed.

The working principle of the embodiment is as follows:

after the control chip 4 monitors that the toilet lid body 1 is closed through the closing sensor 6, the VOC sensor 3 is started; then the control chip 4 monitors the concentration of the organic volatile matters in the closestool through the VOC sensor 3; when the concentration is greater than a set first threshold value, starting the disinfection device 5; until the concentration of organic volatiles in the toilet is less than a set second threshold, the disinfection device 5 is deactivated. Wherein the setting of the second threshold is smaller than the first threshold.

When the VOC sensor 3 or the disinfection device 5 is in a working state, if the control chip 4 monitors that the toilet lid body 1 is opened through the closing sensor 6, the current work of the VOC sensor 3 and the disinfection device 5 is stopped immediately. After the toilet lid is prevented from being opened by mistake, the disinfecting equipment is prevented from harming the human body, and the safety is further improved.

In another embodiment, the intelligent disinfection toilet lid is further connected with a driving mechanism of the control chip 4 for opening and closing the toilet lid body 1. The driving mechanism can adopt the form of mutually connecting a hinge and a motor, and two ends of the hinge are respectively connected with the toilet cover body 1 and the toilet. Realize the self-closing of toilet lid through actuating mechanism, realize regularly automatic monitoring and disinfection, promote the convenience degree of using.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
