The current air treatment device needs to treat pollutants such as formaldehyde, benzene series and the like, and is evolved mainly in an adsorption mode. The air flow flows into the shell of the air treatment device through the air inlet, and after flowing through the purification net, the purification net absorbs pollutants such as formaldehyde, benzene series and the like on the purification net. Like this, the reduction that can show is from the pollutant content in the air current of air outlet outflow, realizes the absorption purification to the air. However, since the purification net includes the carrier and the adsorbent. And it is mainly an adsorbent coated on a carrier to adsorb contaminants. The existing adsorbent is easy to be saturated. After the adsorption saturation, the purification net loses the adsorption purification function. Therefore, the purification net needs to be frequently disassembled and replaced, and the operation of a user is inconvenient. In addition, the pollutants stay on the purification net, and after the purification net is saturated in adsorption, the pollutants on the purification net are easily brought into the room by the airflow. This arrangement is likely to cause secondary pollution.
Referring to fig. 1 to 3, the present invention provides an air treatment device 100, wherein the air treatment device 100 includes a housing 11, a first wind wheel 12, a purification net 13 and a heating body. An accommodating cavity is arranged in the shell 11, and an air inlet 11a and an air outlet 11c which are communicated with the accommodating cavity are arranged on the shell 11. The first wind wheel 12 is arranged in the accommodating cavity; the purification net 13 is arranged adjacent to the air inlet 11 a; (ii) a The heating body is attached to the purification net 13. The air treatment device 100 has a desorption mode. When the air treatment device 100 is in the desorption mode, the heating body is turned on, the pollutants on the purified net 13 are desorbed by heating, and the air flow flows in from the air inlet 11a and flows out from the air outlet 11c carrying the pollutants.
We have found that during the adsorption process of the purification net 13, it is mainly the adsorption of the contaminants such as aldehyde, benzene, etc. by the adsorbent. These contaminants also tend to accumulate within the adsorbent. The adsorbent is heated to catalytically desorb the contaminants from the adsorbent by heating. It has been found, in practice, that the contaminants can be desorbed at temperatures between 70 c and 100 c in the purification web 13.
Therefore, we propose an air treatment device 100 with a desorption mode. The air treatment device 100 is provided with a heating body in contact with the purification net 13. The heating body can be controlled to be opened and closed. When the air treatment device 100 is in the desorption mode, the heating body is turned on to heat the purification net 13. So that contaminants are no longer tightly adsorbed in the purification net 13. In one embodiment, the flow path of the air treatment device 100 is further designed, that is, the air treatment device 100 is further provided with an air outlet 11c communicated with the outside. So that in the desorption mode, after the air flow flowing in from the air inlet 11a passes through the heated purification net 13, the pollutants carrying these and the purification net 13 flow out from the air outlet 11 c.
In this way, the desorption mode of the air treatment device 100 can be turned on when the contaminants on the purification net 13 are accumulated to a certain degree. To desorb the contaminants and discharge them outdoors. In this way, the adsorption capacity of the purification net 13 can be restored again, and the purification net 13 does not need to be separately removed and replaced. The problem of user's needs often dismantle the change purification net 13 is solved. In addition, the desorption mode discharges the pollutants in the air treatment device 100 to the outside through the air outlet 11c, so that the pollutants are prevented from accumulating in the air treatment device 100 and causing secondary pollution.
In another optional embodiment, the housing 11 is further provided with an air outlet 11b communicated with the accommodating cavity. The housing 11 is further provided with an air outlet baffle 112 and an air outlet baffle 113, and when the air treatment device 100 is in the desorption mode, the air outlet baffle 112 closes the air outlet, that is, the air outlet baffle 112 blocks the air outlet 11b and the accommodating cavity. The air treatment device 100 also has an adsorption mode. When the air treatment device 100 is in the adsorption mode, the air outlet baffle 113 closes the air outlet 11c, the air outlet baffle 113 blocks the accommodating cavity and the air outlet 11c, the heating body is closed, and air flows from the air inlet 11a, passes through the purification net 13 and flows out from the air outlet 11 b.
Specifically, the air treatment device 100 has an adsorption mode in addition to a desorption mode. The adsorption mode is used for adsorbing and purifying pollutants such as formaldehyde, benzene and the like in a room. The purification mesh 13 is not heated at this time. And the shell 11 is also provided with an air outlet 11b, the air outlet 11b is arranged facing indoors, and the air inlet 11a is also arranged facing indoors. The first wind wheel 12 moves to suck air with high indoor pollutant content from the air inlet 11 a. And these gas streams are caused to pass through the purification mesh 13, in the process of which contaminants entrained in the gas streams are adsorbed by the purification mesh 13. That is, the air flows are purified by the purifying net 13 and then flow back to the room through the air outlet 11 b. Thereby completing the adsorption mode, i.e., the process of purifying the indoor air.
And contaminants in the room are accumulated on the purification net 13 during the adsorption process. The purification net 13 may further be provided with a sensor, and when the sensor detects that the pollutants accumulated on the purification net 13 reach a threshold value, the sensor controls the air treatment device 100 to switch from the adsorption mode to the desorption mode, desorbs the pollutants on the purification net 13, and discharges the pollutants outdoors. Besides the scheme of automatic switching, the air treatment device provided by the utility model can also adjust the adsorption mode and the desorption mode in a manual switching mode. The air treatment device 100 is also provided with an indicator light connected to a sensor. The user can determine whether the contaminants have accumulated to the threshold value on the purification net 13 according to the indicator light. And determines whether to turn on and off the desorption mode.
Meanwhile, the flow paths of the adsorption mode and the desorption mode of the air treatment device 100 do not interfere with each other. When the air processing device 100 is in the adsorption mode, the air outlet baffle 113 blocks the first wind wheel 12 and the air outlet 11c, and the air inlet 11a and the air outlet 11b are communicated with the first wind wheel 12. When the air processing device 100 is in the desorption mode, the air outlet baffle 112 blocks the air outlet 11b, and the first wind wheel 12 is connected to the air inlet 11a and the air outlet 11 c.
It is noted that the heating body is an electric heating body. And the electric heater is connected to an electric generating device (e.g., a power source) to energize the electric heater when the air treatment device 100 is in the desorption mode. The large electric heaters generate heat when energized. And transfers the heat to the purification net 13, so as to realize the heating desorption of the purification net 13.

Compared with the scheme that the heating body is contacted with the purification net 13, the scheme that the heating body is embedded into the purification net 13 increases the contact area between the heating body and the purification net 13, and the purification net 13 can be heated more quickly. It should be noted that, in order to prevent the plurality of third heating bodies 143 embedded in the purification net 13 from affecting the adsorption effect of the purification net 13 itself, the plurality of third heating bodies 143 are disposed at intervals, and the accommodating grooves are also disposed at corresponding intervals.
In an alternative embodiment, the number of the third heating bodies 143 is not less than 2, and not more than 30. Alternatively, the number of the third heating bodies 143 may be 4, 5, 6, 7, or 8.
