With the improvement of people's living standards, many smart appliances have entered people's lives, and air purifiers are one of the types of people's daily use. The existing purifiers cannot kill viruses, and in the process of circulating and purifying the air, it may cause secondary pollution to the air, which will bring adverse effects on the health of users and the living environment. In the prior art, most air purifiers usually use thermal disinfection to kill viruses on the air passing through the filter. Because high temperature can inactivate the virus, it takes time for the virus to inactivate in a high temperature area, not immediately. Therefore, when the air passes through the filter, the virus cannot be effectively killed because the air flow rate is too fast. And in order to ensure the effectiveness of high-temperature antivirus, although the longer the time, the better the effectiveness of the antivirus, but the durability of the filter is related to the heating time, the longer the heating time, the shorter the durability. The temperature resistance of the filter screen itself limits the upper limit of temperature rise. The above-mentioned factors make the current air purifiers unable to effectively kill viruses, causing secondary pollution to the air, and adversely affecting the health of users and the living environment. The air purifying device provided by the embodiment of the present invention can solve the problem that the air purifier in the prior art cannot effectively kill viruses, causes secondary pollution to the air, and adversely affects the user's health and living environment.

Example 1

As shown in FIG. 1 , an embodiment of the present invention provides an air purification device, which includes a body, a humidity detection device, a controller, an adsorption device 3 and a sterilization device 4 .

In the embodiment of the present invention, the body has an air inlet 1 and an air outlet 7, the air inlet 1 is arranged at the first end of the body, and the air outlet 7 is arranged at the second end opposite to the first end. Inside the body, an air circulation channel 5 is formed between the air inlet 1 and the air outlet 7 . Under the action of the fan 2 inside the main body, the air flows from the air inlet 1 to the air outlet 7 through the air circulation channel 5 . The adsorption device 3 is arranged in the air circulation channel 5 and is adapted to cover the air circulation channel 5 . Since the virus in the air requires the host to contain water vapor and aerosol in the air, the adsorption device 3 can adsorb the water vapor and the aerosol, and also adsorb the virus. The sterilization device 4 is also arranged in the air circulation channel 5 , and the sterilization device 4 is located upstream of the adsorption device 3 in the direction of air flow. The humidity detection device is arranged in the air circulation channel 5 , and in the air flow direction of the air circulation channel 5 , the humidity detection device is located downstream of the adsorption device 3 . The controller is arranged on the main body, and is connected to the sterilization device 4 and the humidity detection device in electrical communication and communication at the same time. The liquid sterilizing medium can be commonly used medical alcohol or other high-concentration alcohol, or other types of liquid sterilizing medium. For the selection of liquid bactericidal substances, the first choice is non-toxic and harmless to the human body.

In this way, the controller is communicated with the sterilization device 4, so that the liquid sterilization medium released by the sterilization device 4 is directly adsorbed by the adsorption device 3 during the air flow process. Because the liquid sterilization medium can instantly inactivate the virus, no inactivation time is required. Therefore, the virus adsorbed on the adsorption device 3 can be directly killed, the antivirus efficiency is improved, and the secondary pollution to the air is avoided, thereby ensuring the health of the user and improving the living environment. At the same time, the technicians found that after the sterilization device sprays the liquid sterilization medium on the adsorption device for a period of time, the humidity of the adsorption device will tend to be saturated. If the spraying continues, the adsorption device itself will not be able to absorb it. drop, thereby causing waste of liquid sterilization medium, and at the same time, the dripping liquid sterilization medium will cause damage to the structure below it.

In addition, by setting the humidity detection device, the frequency of releasing the liquid sterilization medium from the sterilization device 4 can be controlled according to the actual humidity on the adsorption device 3. When the humidity detection device detects that the area of the adsorption device is saturated or saturated, the controller can control the sterilization device. The device stops spraying, and after the humidity of the adsorption device is reduced, the spraying work is restarted, thereby improving the disinfection efficiency of the air purification device.

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 . After the adsorption device 3 absorbs the liquid sterilization medium, the humidity becomes high, and the controller controls the sterilization device 4 to stop working. Generally, when the adsorption device 3 with a default humidity of 100% contacts the liquid sterilization medium, the adsorption device 3 cannot absorb the liquid sterilization medium.

Optionally, in some embodiments of the present invention, the air purification device further includes a drying device 8 disposed in the air circulation channel 5 and adapted to cover the air circulation channel 5 . The drying device 8 is located upstream of the sterilization device 4 in the air flow direction of the air circulation channel 5 .

In the present invention, by setting the drying device 8, the water vapor entering the air in the air circulation channel 5 can be absorbed, so as to ensure that the air passing through the adsorption device 3 is dry air, and it can be ensured that the adsorption device 3 and the liquid sterilization in the sterilization device 4 are only sterilized. The contact of the medium will not reduce the concentration of the liquid sterilization medium due to water vapor, thereby further improving the sterilization efficiency of the air purification device.

The drying device 8 may be a filter screen attached with quicklime, or an air permeability device attached with a material for absorbing water vapor, which can play the role of absorbing moisture.

The sterilization device 4 has a built-in liquid level detection device, and the liquid level detection device is connected in communication with the controller. In the present invention, by setting the liquid level detection device, the storage condition of the liquid sterilization medium inside the sterilization device 4 can be detected in real time. For example, judging whether the storage of the liquid sterilization medium is higher than one third, if the liquid level of the liquid sterilization medium is lower than one third, the air purification device will automatically remind that the liquid sterilization medium is insufficient, which can effectively avoid the shortage of the liquid sterilization medium. , the air purification device can not play a sterilizing effect. When it is less than one tenth, start to reduce the spray volume or stop spraying the liquid sterilization medium.

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 for illustration.

Optionally, in some embodiments of the present invention, the sterilization device 4 is a sterilization atomizer, and the sterilization atomizer is suitable for spraying the liquid sterilization medium onto the adsorption device 3 in a mist form. By setting the sterilizing device 4 as a sterilizing atomizer, the present invention can cover the adsorption device 3 to the greatest extent, and can reduce the usage of liquid sterilizing medium while covering the adsorption device 3, thereby improving the sterilizing efficiency and reducing the cost.

In the embodiment of the present invention, the sterilization atomizer includes a nozzle, an electronically controlled pressure spraying device and an alcohol storage tank, the spraying range of the nozzle is suitable for covering the adsorption device 3, and the electronically controlled pressure spraying device is used to spray the alcohol in the alcohol storage tank to The mist is sprayed onto the adsorption device 3, and the liquid level detection device is arranged inside the alcohol storage tank. The liquid sterilization medium can be alcohol with a concentration of more than 75%, usually 75% medical alcohol can be used. Alcohol is regularly sprayed on the adsorption device 3 and is effectively adsorbed by the adsorption device 3. The amount of alcohol sprayed through the test can keep the adsorption device 3 moist under certain conditions, and the moist value is kept in the situation that can effectively disinfect the virus. Those skilled in the art The moisturizing degree can be matched according to the actual disinfecting intensity.

When starting the disinfection function of the air purification device, the user is required to select the disinfection intensity, and the disinfection intensity corresponds to three options: strong, medium and weak. Due to the strong volatility of alcohol, the spray interval time and the air volume of fan 2 form a matching relationship in the early stage, which corresponds to:

1. Strong: the fan 2 is at full speed, and the alcohol atomizer sprays when the humidity of the adsorption device 3 is lower than 95%;

2. Medium: the fan 2 rotates at a moderate speed, and the alcohol atomizer sprays when the humidity of the adsorption device 3 is lower than 85%;

3. Weak: The fan 2 is running at a small load, mainly to ensure that the noise is extremely low, and the alcohol atomizer spray is detected when the humidity of the adsorption device 3 is lower than 75%.

Those skilled in the art can change the disinfection gear and the humidity of the adsorption device 3 according to the actual situation. The wind speed of the air purification device is different, and the humidity of the adsorption device 3 is different, which will cause the alcohol volatilization rate to be different. In order to keep the filter screen with 100% anti-virus ability and consume as little alcohol as possible, those skilled in the art can match it through experiments during production.

The adsorption device 3 can be a high-efficiency filter. The high-efficiency filter also has a strong absorption capacity for liquid particles. The filter has a sponge-like shape, and the absorbed liquid can be evenly stored. Those skilled in the art can change the type of the adsorption device 3 according to the actual situation. The embodiment of the present invention is only for illustration and not limited, and it only needs to play the role of high-efficiency filtration.

Optionally, in some embodiments of the present invention, the air purification device further includes a filter device 6 , which is disposed in the air circulation channel 5 and is adapted to cover the air circulation channel 5 . The filter device 6 is located upstream of the sterilization device 4 in the air flow direction of the air circulation channel 5 . The filter device 6 can be a primary filter or some other filter materials that can absorb dust, and those skilled in the art can make changes according to the actual situation.

By setting the filter device 6 in the present invention, the dust and other impurities in the air can be filtered outside the air purification device, so as to purify the dust and harmful substances in the air in advance, and prevent the particles such as dust from being adsorbed on the adsorption device 3, which is inconvenient for cleaning , at the same time, it has the effect of double filtering, which improves the user experience.

The air purification device further includes a fan 2 , which is arranged on the air flow channel, and is located downstream of the adsorption device 3 in the air flow direction of the air flow channel 5 .

Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For ordinary workers in the field, changes or changes in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And the obvious changes or changes derived from this are still within the protection scope of the present invention.
