Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
As shown in fig. 1, the active air supply type multi-channel air suction hood includes a hood body 1, and according to different use environments, the hood body 1 may be designed into different shapes such as a horn shape and a cone shape, for convenience of description, in this embodiment, the hood body 1 is substantially a hemispherical structure with an open lower end, and an air outlet 11 is provided at a top end for connecting an air suction fan and an air exhaust pipeline.
As can be seen from fig. 2 and 3, the cover body 1 is designed in a multi-layer manner, and collects the gas in the environment through the spherical space 1a at the innermost layer, and forms an exhaust channel 13, an air supply channel 12 and an auxiliary channel 14 in sequence along the spherical space 1a radially outward, and the air supply channel 12 and the auxiliary channel 14 are both independent of the exhaust channel 13.
The exhaust port 11 is communicated to the exhaust passage 13, and a plurality of exhaust holes 13a communicated with the exhaust passage 13 are distributed on the inner wall of the innermost layer of the cover body 1, so that the air suction fan can suck air in the spherical space 1a through the exhaust holes 13 a.
An air supply outlet 12b and an auxiliary air inlet 14a are symmetrically arranged at two sides of the exhaust port 11 and are respectively connected with an air supply fan and an auxiliary fan.
The inner wall of the innermost layer of the cover body 1 is provided with a plurality of air supplement ports 12a with central symmetry parts at the lower edge, and the air supplement ports 12a are arranged along the tangential direction of the inner wall of the cover body 1 approximately, so that airflow provided by the air supplement fan through the air supplement channel 12 and the air supplement ports 12a can form vortex airflow in the spherical space 1a to attract outside air.
The auxiliary channel 14 and the air supplement channel 12 are communicated through an auxiliary air inlet 14a arranged between the auxiliary channel 14 and the air supplement channel 12, and the direction of the auxiliary air inlet 14a enables the auxiliary air flow provided by the auxiliary fan through the auxiliary channel 14 and the auxiliary air inlet 14a to be introduced into the air supplement channel 12 along the direction perpendicular to or intersecting with the vortex air flow so as to play a role in strengthening the vortex air flow.
The air supply channel 12, the air discharge channel 13 and the auxiliary channel 14 are all provided with air flow control valves for controlling the flow and the flow speed of the air flow, and the air speed, the air pressure and the flow of the outer layer air supply flow and the auxiliary air flow can be controlled within a proper range through the arrangement of the air flow control valves and the corresponding pipe diameters, for example, the air speed, the air pressure and the flow of the outer layer air supply flow and the auxiliary air flow are equal to or slightly smaller than those of the air discharge channel.
Through design air supplement channel 12 and tonifying qi mouth 12a to force the mode of tonifying qi and introduce the new trend and form a vortex air current at cover body 1 inboard, cover the during operation of breathing in, this vortex air current on the one hand can be with the gaseous internal suction of the cover body in the outside to guide its flow direction gas vent 11, on the other hand through the shielding of this vortex air current, can prevent the gaseous loss in the cover body, thereby improve and inhale exhaust efficiency.
The design of the auxiliary channel 14 can facilitate the formation of vortex air flow, and the strength of the vortex air flow can be adjusted by adjusting the air flow introduced by the auxiliary fan.
The air inlet and outlet channels can be converted by means of independent design of each channel; namely, fresh air can be supplemented from the outermost layer, also can be supplemented from the innermost layer, and the air outlet is vice versa; the specific situation is determined according to design data and experimental data, and inward or outward vortex airflow patterns can be formed.
It should be understood that the provision of the exhaust passage 13 and the auxiliary passage 14 is intended to improve the efficiency of air suction and exhaust, and is not a necessary design required for achieving the object of the present invention, and the exhaust passage 13 and the exhaust hole 13a are eliminated, and the air suction fan can still directly act on the spherical space 1a through the exhaust hole 11 to suck the air therein. Without the auxiliary passage 14 providing the auxiliary air flow, a swirling air flow can still be formed in the housing 1 by a reasonable control of the air supply fan and the air supply passage 12.
Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
