Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
The existing passenger car adopts a mode of installing a ventilation fan on a roof skylight to exhaust turbid air in the car, only one or two roof air outlets are arranged, the ventilation effect is not ideal, and the passenger car always has unpleasant smell when entering the car; and the air current flows from the floor to the skylight during ventilation and flows from the periphery to the middle part, so that passengers are easy to contact more dirty air, even bacteria and viruses to cause infection.
Referring to fig. 1 and 2, in view of the above, the present embodiment provides a negative pressure vehicle body frame ventilation system, which includes a ventilation pipeline 2 installed in a vehicle body frame 1, and exhausts air in a vehicle compartment to the outside of the vehicle body through the ventilation pipeline 2, so as to form a negative pressure isolation space in the vehicle body, thereby accelerating air circulation between the inside of the vehicle compartment and the outside.
Specifically, the vehicle body framework 1 is formed by connecting a plurality of steel materials, and comprises a stand column along the height direction of the vehicle body and a cross bar along the length direction and the width direction of the vehicle body. The upright columns positioned on two sides of the side window of the vehicle body are side window upright columns 7, tubular through holes are coaxially formed in the side window upright columns 7, and the ventilation pipelines 2 are all installed in the tubular through holes in the side window upright columns.
Wherein, the air inlet 3 rather than the inside pipeline intercommunication of taking a breath is all seted up to the side that is located the side window stand 7 in the carriage, and this air inlet 3 all faces one side at passenger place, and air inlet 3 is located the middle part region that side window stand 7 is located the carriage part. The lower ends of all the ventilation pipelines 2 extend out of the side window upright post 7 and then extend to the lower end of the carriage bottom plate and are communicated with an air inlet pipe 4 positioned at the lower end of the carriage bottom plate, the air outlet end of the air inlet pipe 4 is communicated with the air inlet end of a fan 5 positioned at the lower end of the carriage bottom plate, the air outlet end of the fan 5 is communicated with the air inlet end of an air purifier 8 positioned at the lower end of the carriage bottom plate through an exhaust pipe, and the air outlet end of the air purifier 8 extends out of the vehicle body through a pipeline.
Preferably, the air inlets 3 formed in each side window pillar 7 are at the same height as the mouths of seated and standing passengers, respectively, so that the air exhaled from the mouths of the passengers can rapidly enter the ventilation pipeline through the air inlets and then be exhausted through the ventilation pipeline.
This air exchange system is when using, and in fan 5 inhales each ventilation pipe 2 with the air in the carriage, then carry to air purifier 8 in through exhaust pipe 4, through air purifier 8 purification filtration back, carry outside the automobile body, at this moment, because the air in the carriage is taken out to the outside, make the interior negative pressure isolation space that forms of carriage, and then make outside air get into in the carriage through the ventilation window of seting up in the automobile body roof. The circulation speed of the air inside the carriage and the outside air is greatly increased, so that the air quality in the carriage is greatly improved, and the propagation of bacteria and viruses is reduced.
Therefore, the invention discharges the turbid air in the vehicle in the fastest speed and shortest way, so that a negative pressure isolation space is formed in the vehicle, and the quality of the air in the vehicle is greatly improved; simultaneously, the combustion gas passes through the outside of the car of discharge after filtration purification, avoids causing the atmosphere pollution, and this system has the advantage at high efficiency, convenient, full coverage, no dead angle.
In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
