Embodiment approach 1
[0035] Such as figure 1 , figure 2 As shown, it is a fresh air ventilator of the present invention. The ventilator includes a closed casing 1, and the casing 1 is composed of a front half casing 11 and a rear half casing 12. The closed casing The casing 1 is respectively provided with a first opening 110 leading to the indoor and a second opening 120 leading to the outdoor. The closed casing 1 is located between the first opening 110 and the second opening 120, swinging Ground is provided with a centrifugal fan 2, and this centrifugal fan 2 is provided with air inlet 21 and air outlet 22 (as shown in Figure 3, Figure 4), and the air inlet 21 of described centrifugal fan and air outlet 22 correspond to switch respectively Conducted to the first opening 110 and the second opening 120 .
[0036] From the above, the centrifugal fan 2 of the fresh air ventilator of the present invention has two working positions, and the fan 2 is switched between the two working positions by mea...
Embodiment approach 2
[0044] The principle and structure of this embodiment are basically the same as Embodiment 1, the difference is that figure 1 , Figure 7 and Figure 8 As shown, a filter device 3 is provided in the housing 1 adjacent to the second opening 120 to seal the second opening 120 from the upper part of the housing 1 .
[0045] With such a structure, when the ventilator is sucking air, the air that enters the room from the outside through the second opening 120 is first filtered by the filter device 3, and the filtered air is sucked into the room by the centrifugal fan 2 to make it enter the room. The air is purified for good health.
[0046] In this embodiment, the filter device 3 includes a slot 31 provided on the housing 1 and a filter element 32 inserted in the slot 31 . The filter element 32 can also be provided with a silver ion filter layer to realize the functions of silver ion sterilization and purification.
[0047] In this embodiment, if figure 1 As shown, the filter de...
Embodiment approach 3
[0052] The principle and structure of this embodiment are basically the same as Embodiment 2, the difference is that figure 1 , figure 2 , Figure 6-Figure 8 As shown, the second opening 120 side on the back side of the housing 1 is provided with a third opening 121 leading to the interior; a wind plate (such as Figure 9 , Figure 10 As shown), the wind plate 4 is provided with a ventilation hole 41, and the ventilation hole 41 on the wind plate can be switched to correspond to the second opening 120 and the third opening 121.
[0053] When the ventilator of the present invention performs indoor and outdoor ventilation, the air vent 41 of the wind plate 4 is moved to a position corresponding to the second opening 120, so that the second opening 120 communicates with the air vent 41 (such as Figure 10 shown), at this time, the ventilator can perform indoor and outdoor ventilating functions through the second opening 120 .
[0054] When the ventilator of the present inven...
