Air changing device for compartment of ambulance

Abstract

The invention discloses an air changing device for a compartment of an ambulance. The air changing device comprises an independent fresh air outlet, an independent fresh air supplying way, an independent polluted air inlet, an independent polluted air exhaust way and an engine room. Filtering devices are arranged in the independent fresh air supplying way and the independent polluted air exhaust way, an air inlet and outlet opening communicated with the air outside the compartment is formed in the engine room, the engine room is further provided with a movable valve, the fresh air supplying way and the polluted air exhaust way are provided with openings in the engine room, the valve can completely seal any one of the openings, and a draught fan is further arranged in the engine room. According to the air charging device for the compartment of the ambulance, fresh air supplying and polluted air exhausting are separated, fresh air cannot be secondarily polluted, due to the fact that the configuration of a power device is omitted, the production cost is saved, the work of maintenance personnel of the ambulance is reduced, and due to the fact that the configuration of the power device is omitted, the probability of faults of a system is also lowered to a certain degree.

Description

technical field [0001] The invention relates to the field of air treatment, in particular to an ambulance compartment ventilation device. Background technique [0002] At present, the air intake and outlet of the air ventilation system in many ambulances are in the same passage. Although this saves space, because the air intake and outlet are in the same passage, it is easy to cause the fresh air drawn in from outside the car. Contaminated by the bacteria-laden air in the car, which has a negative impact on the health of the ambulance personnel. There are also some ambulances that completely release the new air intake system and the air exhaust system in the cabin, and set up two sets of independent air passages, two sets of independent filtration and sterilization devices, and two independent power systems, so that although the fresh air will not The secondary pollution protects the health of the ambulance personnel in the compartment, but the two independent systems not...

Problems solved by technology

[0002] At present, the air intake and outlet of the air ventilation system in many ambulances are in the same passage. Although this saves space, because the air intake and outlet are in the same passage, it is easy to cause the fresh air drawn in from outside the car. Negative health effects of ambulance personnel due to contamination by airborne bacteria in the vehicle compartment

There are also some ambulances that completely release the new air intake system and the air exhaust system in the cabin, and set up two sets of independent air passages, two sets of independent filtration and sterilization devices, and two independent power systems, so that although the fresh air will not The secondary pollution protects the health of the ambulance personnel in the compartment, but the two independent systems not only increase the production cost of the vehicle, but also increase the maintenance cost in the future, and the failure rate of the two systems is also higher than that of one system
