Example 1
As shown in fig. 1, an embodiment of the present invention provides an air purification apparatus including a body, an adsorption apparatus 3, and a sterilization apparatus 4.
In the embodiment of the invention, the body is provided with an air inlet 1 and an air outlet 7, the air inlet 1 is arranged at a first end of the body, and the air outlet 7 is arranged at a second end opposite to the first end. An air circulation channel 5 is formed between the air inlet 1 and the air outlet 7 in the body. Air flows from the air inlet 1 to the air outlet 7 through the air circulation channel 5 under the action of the fan 2 in the body. The adsorption means 3 is arranged in the air flow channel 5 and is adapted to cover the air flow channel 5. Since viruses in the air are water vapor and aerosol which are contained in the air and require a host, the adsorption device 3 can adsorb the viruses while adsorbing the water vapor and the aerosol. A sterilising device 4 is also arranged in the air flow channel 5, the sterilising device 4 being located upstream of the suction device 3 in the direction of the air flow, the sterilising device 4 being adapted to release sterilising medium towards the suction device 3. The sterilization medium can be medical alcohol commonly used or other high-concentration alcohol, or other gaseous sterilization substances. For the selection of the gaseous sterilizing substances, the substances are preferably nontoxic and harmless to human bodies.
So set up, through setting up sterilizing equipment 4 for the bactericidal medium of sterilizing equipment 4 release is directly adsorbed by adsorption equipment 3 at the air flow in-process, because the bactericidal medium can make the virus inactivation in the twinkling of an eye, need not the inactivation time, thereby can directly kill the virus that adsorbs on adsorption equipment 3, has improved virus killing efficiency, has avoided the secondary pollution who causes the air, thereby has guaranteed that the user's is healthy, has improved living environment.
Optionally, in some embodiments of the present invention, the air purification apparatus further comprises a controller, and the controller is disposed on the body and is in communication connection with the sterilization device 4. The working range of the sterilising medium which is released by the sterilising means 4 when it is in operation is adapted to cover the suction means 3.
The controller is arranged and is in communication connection with the sterilizing device 4, so that the sterilizing device 4 can release sterilizing media at regular intervals, and the air purifying device can automatically sterilize. In addition, the user can also reduce the interval time for releasing the sterilization medium according to the actual situation, thereby improving the sterilization efficiency of the air purification device. The skilled person can also set the interval time in the controller in advance, the setting of the interval time length can be adjusted according to the actual situation, and the interval time is not limited in this embodiment.
In addition, the sterilization medium released by the sterilization device 4 covers the adsorption device 3, so that the sterilization medium is available in all places of the adsorption device 3, the sterilization capacity of the adsorption device 3 can be increased to the greatest extent, and the sterilization efficiency of the air purification device is improved.

When the sterilization medium is in a liquid state, such as alcohol, a liquid level detection device can be arranged in the medium accommodating cavity and is in communication connection with the controller. The liquid level detection device is arranged, so that the storage quantity condition of the sterilization medium in the sterilization device 4 can be detected in real time. For example, whether the storage amount of the sterilization medium is higher than one third is judged, if the liquid level of the sterilization medium is lower than one third, the air purification device can automatically remind that the sterilization medium is insufficient, and therefore the situation that the air purification device cannot perform the sterilization function when the sterilization medium is insufficient can be effectively avoided. When the amount is less than one tenth, the amount of spray is reduced or the spraying of the sterilizing medium is stopped.
Those skilled in the art can change the judgment node of the liquid level detection device according to the actual situation, and this embodiment is only an example.
Optionally, in some embodiments of the present invention, the sterilization device 4 is a sterilization atomizer adapted to spray sterilization medium onto the adsorption device 3 in the form of mist. According to the invention, the sterilization device 4 is set as the sterilization atomizer, so that the adsorption device 3 can be covered to the maximum extent, and the usage amount of sterilization medium can be reduced while the adsorption device 3 is covered, thereby improving the sterilization efficiency and reducing the cost.
In the embodiment of the invention, the sterilization atomizer comprises a nozzle, an electric control pressure injection device and an alcohol storage tank, wherein the spray range of the nozzle is suitable for covering the adsorption device 3, the electric control pressure injection device is used for spraying alcohol in the alcohol storage tank onto the adsorption device 3 in a mist shape, and the liquid level detection device is arranged inside the alcohol storage tank. The sterilization medium may be alcohol with a concentration of 75% or more, and usually 75% medical alcohol. Alcohol is regularly sprayed onto the adsorption device 3 and is effectively adsorbed by the adsorption device 3, the alcohol spraying amount can keep the adsorption device 3 moist under certain conditions through test matching, the wetness value is kept under the condition that viruses can be effectively killed, and a person skilled in the art can correspondingly match the moisture retention degree according to the actual killing intensity.
When starting the disinfection function of the air purification device, the user is required to select the disinfection intensity, which corresponds to three options of strong, medium and weak. Because the volatility of the alcohol is very strong, the spraying interval time and the air quantity of the fan 2 form a matching relation in the early period, which respectively correspond to that:
1. strong: the fan 2 rotates at full speed, and the alcohol atomizer sprays the alcohol once every 5 min;
2. the rotation speed of the medium air blower 2 is moderate, and the alcohol atomizer sprays the alcohol once every 15 min;
3. weak: the fan 2 operates under a small load, mainly ensuring that the operation is carried out under the condition of extremely low noise, and the alcohol atomizer sprays once every 30 min.
The technical personnel in the field can change disinfection gear and spraying interval according to actual conditions, and air purification device's wind speed is different, and adsorption equipment 3 humidity is different, and air humidity is different and all can cause the alcohol rate of volatilizing different. In order to keep the filter screen at 100% disinfection capacity with as little alcohol as possible, one skilled in the art can match it by trial at the time of production.
