Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention.

Referring to fig. 1, a sterilizer according to an embodiment of the present invention includes: a processor 100 disposed inside the sterilizer, an LED light source 200 for emitting ultraviolet rays and a temperature sensor 300 disposed on a surface of the sterilizer;

wherein, the LED light source 200 and the temperature sensor 300 are respectively connected to the processor 100.

In practice, the temperature sensor 300 detects the temperature of the environment where the sterilizer is located in real time and transmits the detected temperature to the processor 100; the processor 100, after receiving the temperature transmitted from the temperature sensor 300, adjusts a preset reference sterilization time using the received temperature to obtain a sterilization time.

The reference sterilization time is also a time determined according to the sterilization mode selected by the user. In particular, the sterilization modes may be: a baby dish mode, a baby toy mode, a baby clothes mode, an adult dish mode, an adult clothes mode, and the like; and each sterilization mode corresponds to a reference sterilization time. In one implementation, the reference sterilization time may be obtained by counting the time required for completely sterilizing the object to be sterilized corresponding to each sterilization mode at the same target temperature, for example, the target temperature is 30 ℃.

In one implementation, the sterilizer can be provided with a mobile communication interface for communicating with the mobile device, when the user needs to use the sterilizer to sterilize, an APP (Application) for controlling the sterilizer can be installed on the mobile device, then the mobile device is connected with the sterilizer through the interface, and after the connection is successful, the user can control the sterilizer to sterilize through the function provided by the APP. In particular, multiple sterilization modes may be provided on the APP, and the processor 100 determines a baseline sterilization time after a user selects one of the sterilization modes. The mobile communication interface is an OTG interface; for example, the OTG interface may be at least one of a microsusb interface, a Type-C interface, and a Lightning interface. The sterilizer passes through OTG interface and mobile device sharing power and screen to when reducing manufacturing cost, reduce the occupation space of product.

In the implementation, the processor with USB function is usually expensive, and in order to reduce the production cost of the sterilizer, a processor without USB function, such as a single chip, may be used, and in this implementation, the sterilizer further includes: a communication conversion circuit; the processor without the USB function is connected with the OTG interface through the communication conversion circuit, so that the power supply and the display screen are shared by the OTG interface and the mobile device, and the use cost of the processor in the sterilizer is reduced. In one implementation, the communication conversion circuit may be: one of a serial port circuit, an I2C bus circuit, and an SPI interface circuit.

In another implementation, a control panel may be further disposed on the sterilizer, and after the sterilizer is powered on, the control panel displays various sterilization modes, each sterilization mode corresponds to a reference sterilization time, and after the user selects a sterilization mode, the processor 100 determines the reference sterilization time.

In practice, different bacteria are active differently at different temperatures, but in certain cases can be killed against specific bacteria, such as: the diet firstly kills escherichia coli; the first suppurative bacteria of the wound class; dermatitis class is the first fungus to be killed. In the case of E.coli, the activity increases with increasing temperature at temperatures between 0 and 40 degrees Celsius, and decreases when the temperature reaches a temperature optimum for E.coli survival. Therefore, the required sterilization time varies with the temperature.

Based on this, in the process of obtaining the sterilization time by using the temperature to adjust the reference sterilization time, in one implementation, a difference between the detected temperature and a target temperature at which the reference sterilization time is counted may be calculated, and the larger the obtained difference is, the longer the sterilization time is, which is taken as an adjustment rule, the reference sterilization time is adjusted. For example, the target temperature is 30 degrees, the reference sterilization time is 15 minutes, and when the detected temperature is 35 degrees, the difference is calculated to be +5, based on which the reference sterilization time needs to be increased, and the sterilization time obtained after the reference sterilization time is increased may be 18 minutes; when the detected temperature is 26 degrees, the calculated difference is-4, and accordingly, the reference sterilization time needs to be reduced, and the sterilization time obtained after the reference sterilization time is reduced may be 12 minutes.

In another implementation, a quotient between the detected temperature and the target temperature may be calculated, and the sterilization time may be obtained by multiplying the reference sterilization time by the calculated quotient.

In another implementation, a mapping table may be further established, where the mapping table includes an optimal sterilization time for sterilizing an object to be sterilized at each temperature in different sterilization modes, for example, the mapping table includes: infant dinnerware mode, temperature 30 ℃, optimal disinfection time 15 minutes. After receiving the temperature sent by the temperature sensor 300, the processor 100 searches the mapping table to obtain the optimal sterilization time, and adjusts the reference sterilization time by using the optimal sterilization time to obtain the final sterilization time.

The embodiment of the utility model provides an in the implementation, above-mentioned sterilizer still includes: a humidity sensor disposed on a surface of the sterilizer; the humidity sensor is connected to the processor 100.

The humidity sensor is used for detecting the humidity of the environment where the sterilizer is located and sending the humidity to the processor 100;

in this case, the processor 100 may adjust the reference sterilization time using the temperature and the humidity to obtain the sterilization time after receiving the temperature and the humidity transmitted from the temperature sensor 300 and the humidity transmitted from the humidity sensor.

Specifically, the processor 100 may adjust the reference sterilization time by using the temperature, and after the adjustment is completed, adjust the sterilization time again according to the adjustment rule that the sterilization time is longer as the humidity is higher, so as to obtain the final sterilization time. For example, a sterilization time increase step may be set, that is, a time period defined by the sterilization time increase step per 1% humidity increase, for example, the step is 2 seconds, and when the detected humidity is 20%, the final sterilization time is increased by 40 seconds based on the time obtained by using the temperature adjustment.

The embodiment of the utility model provides an in the implementation, above-mentioned sterilizer still includes: an ambient light sensor disposed on a surface of the sterilizer; the ambient light sensor is connected to the processor 100.

The ambient light sensor sends the light intensity to the processor 100 after detecting the light intensity of the environment where the sterilizer is located;

the processor 100 may adjust the reference sterilization time using the temperature and the light intensity after receiving the light intensity to obtain the sterilization time; specifically, after the reference sterilization time is adjusted by the temperature, the sterilization time may be adjusted again by the adjustment rule that the higher the light intensity is, the longer the sterilization time is, thereby obtaining the final sterilization time.

After receiving the light intensity, the processor 100 may adjust the reference sterilization time by using the temperature and the humidity, respectively, and then adjust the sterilization time again according to the adjustment rule that the higher the light intensity is, the longer the sterilization time is, thereby obtaining the final sterilization time.

Specifically, since the higher the light intensity of the environment, the stronger the "light revival" is, the light intensity can be set to increase by 1 second on the basis of the original time for every 50 lux of the sterilization time. For example, the time obtained after adjustment with temperature and humidity is 600 seconds, the light intensity is 1000 lux, and the final sterilization time is 800 seconds.

The embodiment of the utility model provides an in the implementation, above-mentioned sterilizer still includes: a distance sensor disposed on a surface of the sterilizer; the distance sensor is connected to a processor 100.

In particular, the distance sensor may be located alongside the LED light source 200 on the same end face of the sterilizer.

In practice, as the sterilizer is further away from the object to be sterilized, the irradiation area of the ultraviolet rays on the object to be sterilized is increased, and the intensity of the ultraviolet rays irradiated per unit area by the same ultraviolet light flux is reduced, which results in deterioration of the sterilizing capability. The distance between the sterilizer and the object to be sterilized is detected by the distance sensor, and the processor 100 may guide the user to sterilize using the detected distance.

In one implementation, the processor 100 may calculate an irradiation area of the ultraviolet rays on the object to be sterilized by using the detected distance and the irradiation angle of the LED light source 200 when guiding the user to sterilize by using the detected distance; and then prompting a user to adjust the distance between the sterilizer and the object to be sterilized according to the calculated irradiation area.

Specifically, referring to fig. 2, which is a schematic diagram of calculating an irradiation area according to an embodiment of the present invention, in the diagram, c represents an irradiation angle, d represents a distance between the sterilizer and an object to be sterilized, a represents an irradiation area, o represents a circle center of the irradiation area, and r represents a radius of the irradiation area.

In practice, the radius r may be calculated by a tangent equation using the irradiation angle r and the distance d, and then the irradiation area a may be calculated using the radius r.

In implementation, in the process of prompting the user to adjust the distance between the sterilizer and the object to be sterilized by the processor 100 according to the irradiation area, whether the irradiation area is within the preset interval can be judged, and if so, the user does not need to be prompted to adjust the distance between the sterilizer and the object to be sterilized; if the irradiation area is smaller than the lower limit value of the preset interval, the sterilizer is indicated to be too close to the object to be sterilized, and the user can be prompted to increase the distance between the sterilizer and the object to be sterilized; if the irradiation area is larger than the upper limit value of the preset interval, the fact that the sterilizer is too far away from the object to be sterilized is indicated, and the user can be prompted to reduce the distance between the sterilizer and the object to be sterilized.

In addition, the required disinfection time is linearly proportional to the irradiation area a, that is, the area irradiated by ultraviolet rays on a plane is increased, the ultraviolet irradiation intensity per unit area is reduced due to the same ultraviolet light flux, and the disinfection effect is reduced. Based on this, in one implementation of the embodiment of the present invention, after the reference sterilization time is adjusted using the environmental information of the sterilizer, the irradiation area a is again used for adjustment. For example, an initial irradiation area may be set, and the sterilization time may be increased by 5 seconds for every 1 cm square of the irradiation area based on the initial irradiation area.

Through detecting the sterilizer to waiting the distance between the disinfection object, and then utilize the distance calculation that detects to shine the area to adjust the sterilizer and wait the distance between the disinfection object and change through the suggestion user and shine the area, make and shine the area and be in within the interval of predetermineeing, thereby when guaranteeing the disinfection effect, improve disinfection efficiency.
