Abstract

The invention discloses a negative-pressure fan which comprises an outer shell, a motor located at one end in the outer shell, fan blades arranged at the other end in the outer shell and a rotating shaft connected between the motor and the fan blades. The outer shell of the negative-pressure fan further comprises an air inlet and an air outlet. The negative-pressure fan further comprises a filtering board covering the side of the air inlet; the filtering board further comprises a face net, a back net and a packing layer located between the face net and the back net, wherein the packing layer is activated carbon. By the adoption of the negative-pressure fan, damage, caused by indoor harmful gases, to the human body can be effectively reduced.

Description

technical field [0001] The invention relates to a negative pressure fan, in particular to a negative pressure fan capable of purifying air. Background technique [0002] Negative pressure fan is a device that uses the principle of air convection and negative pressure ventilation to inhale fresh air from the opposite side of the installation site (for example, a door or window), and at the same time force the indoor stuffy air out of the room quickly, so as to achieve cooling and cooling effects. . Compared with general air conditioners, negative pressure fans have the advantages of low cost, large air volume, low noise, low energy consumption, stable operation, long life, and high efficiency. The best choice for ventilation. [0003] see figure 1 as shown, figure 1 It is a cross-sectional view of a negative pressure blower 6 of the prior art. The negative pressure blower 6 as shown in the figure includes a casing 61, a motor 62 positioned at one end of the casing 61, a f...
