The existing humidifiers only have basic atomization and humidification functions in general, and bacteria in the air may be adsorbed in the mist and discharged during humidification, which is harmful to human health. Meanwhile, the bacteria are easy to breed in the water tank.
The existing sterilization methods include ultraviolet ray, ozone, ultrasonic wave, magnetization, static electricity and other treatment methods, which are not widely applied because of complex equipment, small flow of treated water or high treatment costs. With the development of industry, a water source is increasingly subjected to pollution by various organic substances, and it is found that a traditional chlorination disinfection method of a water supply system may produce substances harmful to human body. Therefore, the research on novel alternative sterilization methods has increasingly become a hot topic and an important development trend at home and abroad. Most of the existing commercial electric disinfection water processing devices generate chlorine dioxide, sodium hypochlorite and other disinfectants by electrolysis after adding sodium chloride and other electrolytes. After use, many substances harmful to human body are generated.
Therefore, the present disclosure provides a humidifier for sterilization based on an electrolysis method. The electrolysis method is popular as a sterilization water treatment technology with good sterilization effect, strong usability and no secondary pollution. Electrolytic sterilization may be divided into indirect sterilization and direct sterilization. Indirect sterilization means that ClO−, HClO3, H2O2, O2—, OH— and other substances generated by electrolysis are used to kill microorganisms. Direct sterilization means that electrolytic electrodes are used to directly act on microorganisms to make microorganisms die.
The sterilization and disinfection mechanism of the electrolysis method is as follow: 1. When water with chlorine is electrolyzed, it will generate ClO− and a small amount of chlorate with higher valence, where both ClO— and chlorate are strong oxidants which have strong killing effect on microorganisms; 2. when water without chloride ion is electrolyzed, it will generate ozone, hydrogen peroxide and other strong oxidizing substances, which also have the function of sterilization; and 3. Electrolysis is directly applied on the bacterial cell bodies to destroy bacterial organisms and cause death of the bacteria.
As shown in
In some embodiments, the housing 2 includes an upper cover 7 and a lower cover 8. The upper cover 7 is covered on the lower cover 8 and provided with a groove 18 at the bottom. The lower cover 8 is provided with a bump 19 matched with the groove 18 at the top. Arrangement of the bump 19 within the groove 18 can realize positioning connection between the upper cover 7 and the lower cover 8.
In some embodiments, the upper cover 7 and the lower cover 8 are fixed to each other by interference fit between the groove 18 and the bump 19. Additionally or alternatively, the upper cover 7 is connected with the lower cover 8 by ultrasonic welding. Both the two exemplary fixing modes can avoid the use of bolts, thus avoiding the influence of other metal material on water electrolysis.
In some embodiments, the titanium anode mesh 3 is arranged above the titanium cathode mesh 4. A separator 9 made of insulating material is arranged between the titanium anode mesh 3 and the titanium cathode mesh 4 and is used for separating the titanium anode mesh 3 from the titanium cathode mesh 4. In some embodiments, the insulating material may be polycarbonate.
It should be understood that although
In some embodiments, the titanium anode mesh 3 and the titanium cathode mesh 4 are respectively provided with a first through hole 12 and a second through hole 13. The titanium anode bolt 5 and the titanium cathode bolt 6 respectively pass through the first through hole 12 and the second through hole 13 contactlessly, so as to avoid short circuit caused by the contact between the positive electrode of the power supply and the negative electrode of the power supply. Additionally or alternatively, isolation rings made of insulating material, such as silicone rings may be arranged in the first through hole 12 and the second through hole 13, respectively, so as to further avoid short circuit caused by contact between the positive electrode of the power supply and the negative electrode of the power supply.
In some embodiments, the housing 2 is provided with a first mounting hole 10 and a second mounting hole 11 at the top. The titanium anode bolt 5 and the titanium cathode bolt 6 are respectively arranged in the first mounting hole 10 and the second mounting hole 11, to facilitate positioning and mounting.
In some embodiments, the housing 2 is provided with a waterproof hole 15 at the bottom. A silicone gasket 16 is arranged in the waterproof hole 15. The titanium anode bolt 5 and the titanium cathode bolt 6 respectively pass through the silicone gasket 16. The silicone gasket 16 plays a sealing role to prevent water in the water storage tank 1 from flowing out along the titanium anode bolt 5 or the titanium cathode bolt 6 to cause short circuit. The titanium anode bolt 5 and the titanium cathode bolt 6 are provided with ground coils 14 at the bottom, and the ground coils 14 are respectively fixed to the titanium anode bolt 5 and the titanium cathode bolt 6 by nuts 17 to play a safety protection role.
In some cases, when new water is added into the humidifier 100 or after the electrolytic sterilization module 110 runs for a period of time, the content of bacteria in the water may be low at this time. In this case, if the electrolytic sterilization module 110 is continuously energized, power is wasted. Therefore, in some embodiments, as shown in
In some embodiments, as shown in
In general, when water in the humidifier 100 is replaced with new humidification water, the content of bacteria in the water may be low at this time, so there is no need to turn on the electrolytic sterilization module 110. In this way, by arranging the control device 120, it is possible to determine whether the electrolytic sterilization module 110 needs to be turned on after water in the humidifier 100 is replaced with new humidification water. Specifically, when the humidifier 100 is energized, the detector 121 detects a bacteria concentration value in water and sends the bacteria concentration value to the comparator 122. The comparator 122 compares the received bacteria concentration value with a preset threshold (e.g., 1000 cfu/ml), and sends a comparison result to the controller 123. When the received bacteria concentration value is higher than the preset threshold, the controller 123 controls the electrolytic sterilization module 110 to be turned on, and the electrolytic sterilization module 110 electrolyzes tap water after being turned on, thereby achieving the purpose of electrolytic sterilization. When the received bacteria concentration value is not higher than the preset threshold, the controller 123 controls the electrolytic sterilization module 110 to be turned off, thereby achieving the purpose of saving energy and electricity.
In some embodiments, the detector 121 is configured to periodically detect water quality information, for example, every 2 hours.
In some embodiments, the detector 121 is further configured to detect water level information in the water storage tank 1, and the controller 123 is further configured to control the electrolytic sterilization module 110 to be turned off when a water level in the water storage tank 1 is lower than the titanium anode mesh 3 arranged above. When the water level in the water storage tank 1 is lower than the titanium anode mesh 3 arranged above, if the electrolytic sterilization module 110 is continuously turned on at this time, the electrolytic sterilization module 110 may not only fail to achieve the purpose of electrolytic sterilization, but may also be damaged. Therefore, this problem can be avoided by means of the above setting mode.
