In addition to the above-described embodiments, as shown in fig. 1, 3, 5 and 7, the housing 110 is provided with a mounting groove 114, the mounting groove 114 has an opening formed in the housing 110, and the purification module 150 is mounted in the mounting groove 114 through the opening in a drawable manner.
In the present embodiment, the purification module 150 is detachably mounted to the mounting groove 114. Thereby allowing the purification module 150 to be removed through the opening, facilitating replacement and cleaning of the purification module 150. The number of the mounting grooves 114 corresponds to the number of the purification modules 150 such that each purification module 150 is correspondingly mounted in one of the mounting grooves 114. The opening of the mounting groove 114 is opened on the peripheral wall surface of the housing 110, and the purification module 150 can be mounted into the mounting groove 114 through the opening. It can be understood that the mounting groove 114 of the housing 110 may be formed by a protruding strip, a protrusion, an annular step, a groove, a bracket, etc. for the installation of the purification module 150, and the hollow structure may allow air to pass through, so that when the purification module 150 is installed in the mounting groove 114, the air flow may pass through the purification module 150. In order to facilitate the drawing of the purification module 150, a sliding groove structure may be provided on one of the purification module 150 and the inner wall surface of the housing 110, and a sliding rail structure may be provided on the other, so that the purification module 150 and the housing 110 are connected in a sliding groove and sliding rail manner. By allowing the purification module 150 to be installed in the installation groove 114 in a drawable manner from one side of the housing 110, the structure is simple and the user's operation is facilitated.
Further, referring to fig. 5, 7 and 8, the housing 110 has a rear wall 116 and side wall surfaces 117 connected to both sides of the rear wall 116, and the opening is opened at the front side or the side wall surfaces 117 of the housing 110. It is understood that the first and second decontamination assemblies 130, 140 each include a decontamination module 150. Each purification module 150 is correspondingly installed in one installation slot 114, and can be pulled out of the installation slot 114 through the opening. The wall surface of the opening corresponding to the purification module 150 of the first purification assembly 130 may be the same as or different from the wall surface of the opening corresponding to the second purification assembly 140. That is, the openings corresponding to the purge modules 150 of the first and second purge assemblies 130 and 140 may be opened on the front side or the side wall surface 117 of the housing 110 at the same time, or the opening corresponding to the purge module 150 of the first purge assembly 130 may be opened on the front side/the side wall surface 117 of the housing 110, and the opening corresponding to the purge module 150 of the second purge assembly 140 may be opened on the side wall surface 117/the front side of the housing 110. The opening position of the opening may be designed according to the actual placing position of the fan 120 and the actual placing positions of the first and second purification assemblies 130 and 140. Thus, the user can draw the purification module 150 from the front side or the left and right sides of the housing 110, which is more convenient for the user to operate.
In a preferred embodiment, as shown in fig. 5 to 9, the fan 120 is a double-suction centrifugal fan 120, the double-suction centrifugal fan 120 has two air inlet ends, and the air inlet is communicated with the two air inlet ends.
In the present embodiment, the inner wall surface of the casing 110 and the peripheral wall surface of the double suction centrifugal fan 120 are spaced apart from each other. Specifically, the air inlet is located at the corresponding housing 110 between the two air inlet ends. Therefore, when the double-suction centrifugal fan 120 works, the air flow entering the casing 110 from the air inlet is divided into two parts, which flow to the two air inlet ends of the double-suction centrifugal fan 120 respectively. By using the double suction centrifugal fan 120 to supply air to the air treatment device 100, the air volume is large, and the diameter of the impeller is small, so that the occupied space can be reduced, and the size of the air treatment device 100 can be reduced. And the double suction centrifugal fan 120 can reduce the power of the starting motor and shorten the starting time of the fan 120, so that the control of the air treatment device 100 is more sensitive.
Further, a first purifying assembly 130 is disposed between the two air inlet ends of the double-suction centrifugal fan 120 and the casing 110. Thus, the airflow entering the double-suction centrifugal fan 120 is purified by the first purifying assembly 130, thereby improving the purifying efficiency. And the first purifying assembly 130 is installed between the casing 110 and the air inlet side of the double suction centrifugal fan 120, so that the air flow entering the double suction centrifugal wind wheel can be purified by the first purifying assembly 130, and the space between the casing 110 and the double suction centrifugal wind wheel is fully utilized, so that the structure of the air processing device 100 is more compact, and the overall layout is more reasonable.
In practical application, a primary filter screen or a HEPA screen is disposed between the two air inlet ends of the double-suction centrifugal fan 120 and the casing 110. Then carry out the prefiltration to the new trend, promote the new trend intake when satisfying the purification demand, and can guarantee the inside clean of centrifugal fan 120. Since the air inlet is generally disposed on the rear wall surface of the casing 110, the two air inlet ends of the double-suction centrifugal fan 120 are disposed corresponding to the left and right sides of the casing 110, so that the first purification assembly 130 is disposed along the front-rear direction. In combination with the embodiment in which the purification module 150 is installed in the installation groove 114 in a drawable manner through the opening, the opening can be disposed on the front wall 116 of the housing 110, so that the first purification assembly 130 can be drawn out from the front side, which is convenient and fast, and has a small opening. Of course, in other embodiments, the opening may be provided on the rear wall surface of the housing 110.

A fresh air switch door is usually disposed at the fresh air inlet 111, and specifically, a return air switch door is disposed at the indoor air inlet 115 to open or close the indoor air inlet 115. Thus, the air treatment device 100 has a fresh air purification mode and an indoor purification mode. When the air processing device 100 is in the fresh air purification mode, the return air switch door closes the indoor air inlet 115, the fresh air switch door opens the fresh air inlet 111, the fan 120 drives outdoor air flow to enter the air duct 113 from the fresh air inlet 111, and the outdoor air flow is purified layer by layer through the second purification component 140 or sequentially passes through the first purification component 130 and the second purification component 140 and then is blown out from the air outlet 112, so that the layer-by-layer filtration of fresh air is realized.
When the air processing device 100 is in the indoor purification mode, the return air switch door opens the indoor air inlet 115, the fresh air switch door closes the fresh air inlet 111, the fan 120 drives the indoor air flow to enter the air duct 113 from the indoor air inlet 115, and the indoor air flow is purified layer by the first purification component 130 and the second purification component 140 and then blown out from the air outlet 112. Thus, the air treatment device 100 can circularly purify indoor air, so that the indoor air quality can be improved, the air treatment device 100 is multifunctional, and the product performance is improved.
On the basis of the above embodiment, as shown in fig. 3 to fig. 6, the first purifying assembly 130 and the second purifying assembly 140 are distributed on the upper and lower sides of the fan 120, the indoor air inlet 115 is located on the side of the first purifying assembly 130 facing away from the fan 120, the air outlet 112 is located on the side of the second purifying assembly 140 facing away from the fan 120, and the air inlet is located between the first purifying assembly 130 and the second purifying assembly 140.
