The air inlet assembly includes a fresh air inlet pipe joint 112 and an air inlet pipe component. The air inlet pipe component includes a threaded pipe 113 and an insulation pipe 114. Through the foregoing solution, in the process of using the existing fan, the outdoor air cannot be filtered and purified, so that the unpurified outdoor air inhaled into the human body will also cause certain harm to the human body, and thus the best ventilation effect cannot be achieved. It can be understood that the foregoing solution can be used in the case where outdoor air needs to be filtered and then introduced into the room.

[0023] In this embodiment, the centrifugal fan 108 is driven by the motor of the fan system to suck the outdoor air into the fresh air pipe for filtration and disinfection. Then, the fresh air enters the volute air duct and is sent into the room through the centrifugal fan 108. In this way, a fresh air flow layer will be formed in the room to achieve the ventilation effect.

[0024] Among them, the right blower volute 102 is connected to the left blower volute 101 and is located on one side of the left blower volute 101.

The centrifugal fan 108 is connected to the output end of the centrifugal fan motor 106 and is located on the side of the centrifugal fan motor 106 close to the blower motor base 105. The air inlet assembly is arranged on the left blower volute 101. Two groove-type buckles on the left blower volute 101 are buckled into two hooks on the right blower volute 102. After being buckled in place, the left blower volute 101 and the right blower volute 102 are fixedly connected by screws. The filter element bracket 103 is fixedly connected by buckling on the left blower volute 101, and the connection and support of the filter element bracket 103 are realized through the left blower volute 101. The air purification filter screen 104 is arranged on the filter element bracket 103, and the air entering the left blower volute 101 and the right blower volute 102 can be purified, disinfected and filtered through the air purification filter screen 104. The blower motor base 105 is fixedly connected by buckling in the right blower volute 102, and the connection and support of the blower motor base 105 are realized through the right blower volute 102. The centrifugal fan motor 106 is limited and installed in the corresponding trapezoidal limit groove on the blower motor base 105. The motor bracket 107 is fixedly connected to the blower motor base 105 by screws. The centrifugal fan motor 106 is sleeved through the motor bracket 107, so as to assist in fixing the centrifugal fan motor 106 in the blower motor base 105. The centrifugal fan 108 is connected to the output end of the centrifugal fan motor 106, and the centrifugal fan 108 can be driven to rotate through the driving output of the centrifugal fan motor 106. The air inlet assembly is arranged on the left blower volute 101, and the outdoor air can be inhaled into the left blower volute 101 through the air inlet assembly. Thus, after the left blower volute 101 and the right blower volute 102 are connected and fixed to the motor, the centrifugal fan motor 106 in the right blower volute 102 is driven to drive the centrifugal fan 108 to rotate, so as to inhale the outdoor air into the left blower volute 101 through the air inlet assembly.The air purification filter 104 connected to the left volute 101 of the fan filters and purifies and disinfects the incoming air, so that the generated fresh air enters the air duct of the two volutes and is sent to the room through the centrifugal fan 108. In this way, a fresh air flow layer is formed in the room, thereby achieving the best ventilation effect.

[0025] Secondly, the fresh air inlet pipe joint 112 is connected to the left volute 101 of the fan and is located on one side of the left volute 101 of the fan; the fresh air inlet pipe joint 112 is arranged on the fresh air inlet pipe joint 112, and the fresh air inlet pipe joint 112 has an elastic buckle, through which the elastic buckle of the fresh air inlet pipe joint 112 can be inserted into the square clamping position on the left volute 101 of the fan for cooperation, thereby fixing the fresh air inlet pipe joint 112 on the left volute 101 of the fan, and the air inlet pipe joint 112 is arranged on the fresh air inlet pipe joint 112, through which the fresh air inlet pipe joint 112 can connect the air inlet pipe joint to the left volute 101 of the fan, so that wind can enter the left volute 101 of the fan through the air inlet pipe joint.

[0026] At the same time, the threaded pipe 113 is threadedly connected to the fresh air inlet pipe joint 112 and is located on one side of the fresh air inlet pipe joint 112; the insulation pipe 114 is connected to the threaded pipe 113 and is located on one side of the threaded pipe 113. The threaded pipe 113 is a threaded strip pipe with PVC material. The inner diameter of the threaded pipe 113 is φ28mm~φ30mm; the insulation pipe 114 is integrally fixedly connected to the threaded pipe 113. The insulation effect of the insulation pipe 114 ensures that the temperature inside the pipe does not produce condensation water. At the same time, the external thread of the threaded pipe 113 can cooperate with the internal thread of the fresh air inlet pipe joint 112, so as to facilitate the connection of the insulation pipe 114 to the fresh air inlet pipe joint 112, so that the wind can enter the left volute 101 of the fan through the insulation pipe 114 and the fresh air inlet pipe joint 112.

[0027] In addition, the handle 109 is connected to the filter element bracket 103 and is located on one side of the filter element bracket 103; the elastic buckle 110 is connected to the filter element bracket 103 and is located on one side of the filter element bracket 103, the handle 109 is integrally fixedly connected to the filter element bracket 103, and the elastic buckle 110 is integrally fixedly connected to the filter element bracket 103, and the handle 109 provides a corresponding fulcrum and the elastic buckle 110 fixes the air purification filter 104 on the filter element bracket 103, thereby facilitating the operator to take out the air purification filter 104 from the air conditioner for replacement.

[0028] Finally, the grille 111 is connected to the right volute 102 of the fan and is located on one side of the right volute 102 of the fan.

Through the grille 111, it can prevent mice or sundries from entering the right volute 102 and the left volute 101 of the fan, which may affect the overall operation and use of the fan.

[0029] When using an innovative fresh air replacement fan of this embodiment, after connecting and fixing the left volute 101 and the motor of the right volute 102 of the fan, by driving the centrifugal fan motor 106 in the right volute 102 of the fan to drive the centrifugal fan 108 to rotate, the outdoor air is inhaled into the left volute 101 of the fan through the air inlet assembly. Then, the air entering is filtered, purified, and disinfected by the air purification filter screen 104 connected to the left volute 101 of the fan, so that the generated fresh air enters the air ducts of the two volutes and sends fresh air into the room through the centrifugal fan 108. In this way, a fresh air flow layer will be formed in the room, and then the best ventilation effect can be achieved.
