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
The present invention relates to a kind of negative-pressure air fan, particularly relate to a kind of negative-pressure air fan that can purify air.
Background technique
Negative-pressure air fan is the principle of utilizing cross-ventilation, negative pressure ventilation, for example, by subtend (, gate or the window) inhale fresh air of infield, indoor sultry gas is forced outside discharge chamber rapidly simultaneously, thereby is reached the device of cooling and cooling-down effect.Compare with general air-conditioning, negative-pressure air fan has the advantages such as cost is low, air quantity is large, noise is little, energy consumption is low, operate steadily, the life-span is long, efficiency is high, therefore by increasing industrial and mineral factory building, is utilized, and is the optimal selection that the cooling of modernization workshop is ventilated.
Refer to shown in Fig. 1, Fig. 1 is the sectional view of a kind of negative-pressure air fan 6 of prior art, negative-pressure air fan 6 as shown in the figure comprise shell 61, the motor 62 of shell 61 interior one end, the flabellum 63 of the shell 61 interior the other ends and be connected to motor 62 and flabellum 63 between transmission shaft 64.When negative-pressure air fan 6 work, motor 62 starts, and drives transmission shaft 64 and 63 rotations of connected flabellum, thereby reaches the effect of negative pressure ventilation.
Because environmental deterioration causes harmful gas harm humans healthy, the IAQ problem causing thus has now become the hot issue that people pay close attention to, a lot of air-conditioning producer all classifies air-cleaning function as a necessary functions of new product development, however the rarely seen negative-pressure air fan that can purify the air of a room on the market.
How to provide a kind of negative-pressure air fan that can purify air again simple in structure to become industry problem demanding prompt solution.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of negative-pressure air fan, and it has feature simple in structure, and can effectively purify the air of suction.
For addressing the above problem, the invention provides a kind of negative-pressure air fan, it comprises shell, in shell one end motor, in shell the other end flabellum and be connected to motor and flabellum between transmission shaft, the shell of described negative-pressure air fan further comprises intake grill and exhaust outlet, and described negative-pressure air fan also comprises the filter plate that is covered in described intake grill one side.
Described filter plate further comprises veil, back of the body net and the packed layer between veil and back of the body net.Wherein, described packed layer is active carbon.
Adopt negative-pressure air fan of the present invention can effectively reduce the harm that indoor harmful gas causes human body.
Accompanying drawing explanation
Below, by the description in conjunction with its accompanying drawing to some embodiments of the present invention, can further understand object of the present invention, concrete structure identity and advantage.
Figure 1 shows that the sectional view of the negative-pressure air fan of prior art; And
Figure 2 shows that the sectional view of the negative-pressure air fan of one embodiment of the invention.
Embodiment
