Example 1
As shown in fig. 1, an embodiment of the present invention provides an air purification apparatus, which includes a body, a humidity detection device, a controller, an adsorption device 3, and a sterilization device 4.
The embodiment of the utility model provides an in, the body has air intake 1 and air outlet 7, and air intake 1 sets up the first end at the body, and air outlet 7 sets up the second end that sets up relatively with 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. The sterilizing device 4 is also provided in the air flow passage 5, and the sterilizing device 4 is located upstream of the adsorbing device 3 in the direction of the air flow. The humidity detection device is provided in the air flow passage 5, and is located downstream of the adsorption device 3 in the air flow direction of the air flow passage 5. The controller is arranged on the body and is simultaneously electrically connected with the sterilizing device 4 and the humidity detection device in a communication way. The liquid sterilising medium may be a commonly used medical grade alcohol or other high alcohol concentration, or other types of liquid sterilising medium. For the selection of the liquid sterilizing substance, the liquid sterilizing substance is preferably nontoxic and harmless to human bodies.
So set up, through controller and 4 communication connection of sterilizing equipment for the liquid sterilization medium of sterilizing equipment 4 release is directly adsorbed by adsorption equipment 3 at the air flow in-process, because the liquid sterilization 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 is healthy, has improved the living environment. Simultaneously, the technical staff discovers that after the sterilizing device sprays the liquid sterilizing medium for a period of time to the adsorption device, the humidity of the adsorption device tends to be saturated, if the spraying is continued, the adsorption device can not absorb the liquid sterilizing medium, at the moment, the adsorption device can collect the liquid drops and drip, the waste of the liquid sterilizing medium is further caused, and the liquid sterilizing medium dripping at the same time can cause damage to the structure below the liquid sterilizing medium.
And, through setting up humidity detection device, can be according to the actual humidity on the adsorption equipment 3, control sterilizing equipment 4 releases the frequency of liquid sterilization medium, when humidity detection device detects that the adsorption equipment region is saturated or has saturated, the controller can control sterilizing equipment to stop spraying, waits that the adsorption equipment humidity reduces the back, restarts and sprays work to improve air purification device's virus killing efficiency.
For example, when the humidity detection device detects that the humidity of the adsorption device 3 is lower than 95%, the controller controls the sterilization device 4 to release the liquid sterilization medium and spray the liquid sterilization medium onto the adsorption device 3. The adsorption device 3 absorbs the liquid sterilizing medium and then the humidity thereof becomes high, and the controller controls the sterilizing device 4 to stop operating. Generally, when the adsorption device 3 with the default humidity of 100% contacts the liquid sterilization medium, the adsorption device 3 cannot absorb the liquid sterilization medium, and at this time, droplets of the liquid sterilization medium are collected and dropped on the adsorption device 3.
Optionally, in some embodiments of the present invention, the air purification apparatus further comprises a drying device 8 disposed in the air circulation passage 5 and adapted to cover the air circulation passage 5.

The utility model discloses a set up liquid level detection device, the reserve volume condition of the liquid sterilization medium of 4 inside of sterilizing installation that can real-time detection. For example, whether the storage amount of the liquid sterilization medium is higher than one third or not is judged, if the liquid level of the liquid sterilization medium is lower than one third, the air purification device can automatically remind that the liquid sterilization medium is insufficient, and therefore the situation that the air purification device cannot perform a sterilization function when the liquid sterilization medium is insufficient can be effectively avoided. When the amount is less than one tenth, the amount of the sprayed liquid sterilising medium starts to be reduced or the spraying of the liquid sterilising 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, and the sterilization atomizer is adapted to spray the liquid sterilization medium onto the adsorption device 3 in a mist shape. The utility model discloses a set up sterilizing equipment 4 into the atomizer that disinfects, can be furthest cover adsorption equipment 3 to can reduce the use amount of liquid sterilization medium when covering adsorption equipment 3, thereby can improve virus killing efficiency, reduce the cost.
The embodiment of the utility model provides an in, the atomizer that disinfects includes nozzle, automatically controlled pressure jet equipment and alcohol bin, and the spray regime of nozzle is suitable for covering adsorption equipment 3, and automatically controlled pressure jet equipment is used for spouting adsorption equipment 3 with vaporific with the alcohol in the alcohol bin on, and liquid level detection device sets up inside the alcohol bin. The liquid 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: when the fan 2 rotates at full speed and the humidity of the adsorption device 3 is detected to be lower than 95%, the alcohol atomizer sprays;
2. the method comprises the following steps: the rotating speed of the fan 2 is moderate, and the alcohol atomizer sprays when the humidity of the adsorption device 3 is detected to be lower than 85%;
3. weak: fan 2 is in the low load operation, and the main assurance is gone on in the extremely low condition of noise, detects 3 humidity of adsorption equipment and is less than 75% alcohol atomizer spraying.
Those skilled in the art can change the disinfection gear and the humidity of the adsorption device 3 according to actual conditions, the air speed of the air purification device is different, and the humidity of the adsorption device 3 is different, so that the alcohol volatilization rates are 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.
