Abstract
The utility model relates to an air purifier at the air inlet of an automobile air conditioner, comprising a casing with an air inlet and an air outlet. A plurality of layers of activated carbon fiber felt filtering materials are superposed in the casing, activated carbon fiber feels are clamped between ventilating net sheets and are fixed on the frame of the casing, the upper position of the air inlet direction in the casing is provided with a dust filtering core composed of a plurality of layers of nonwoven fabric felt sheets which are superposed with each other, and the air outlet of the casing is provided with an interface board in sealed butt joint with the air inlet of the automobile air conditioner. Air purified through the air purifier at the air inlet of the automobile air conditioner enters the driver's cab, and the material filtering sheets can be inserted and arranged in the casing of the purifier so as to be convenient replace.
Description
The utility model belongs to the motorcar air conditioner accessory device, particularly is loaded on the air purification unit of air-conditioning ventilation inlet.
Under the automobile door and window closed condition, the air-conditioning ventilation inlet is unique passage that outside air enters operator's compartment.The air-conditioning ventilation inlet of automobile cab does not have air purification unit at present, and the toxic and harmful that the vehicle exhaust that contains in the outside air, asphalt coating overflow can enter operator's compartment through the air-conditioning ventilation inlet, damages driver and crew's health.
The purpose of this utility model is to propose a kind of operator's compartment air-conditioning ventilation inlet air purification unit technical scheme, makes air cleaning in the operator's compartment, with protection driver and crew's health.
Content of the present utility model comprises that one has the housing of inlet and outlet, and the housing inlet and outlet is provided with filter, stacked multilayer active carbon fiber felt filter material in the housing, and active carbon fiber felt is clipped between the gas-permeable nets sheet and is fixed on the case frame.The activated carbon fiber felt is outer can be covered with the layer of non-woven fabric felt.Admission port direction upstream position can be provided with the dust-removing core of the stacked formation of multi-layer nonwoven fabrics felt in shell.The housing air extractor duct is provided with the interface board that can dock with the sealing of air conditioning for automobiles ventilation inlet.Activated carbon fiber filter material sheet and nonwoven fabrics felt dust-removing core sheet are equipped with horse, cooperate with the frame groove insertable type of corresponding setting on the housing.The fibrous filter sheet can be that the W type is stacked to be plugged in the housing.
Characteristics of the present utility model are the air purifiers that are provided with the stacked activated carbon fiber filter material sheet of layering at the air-conditioning ventilation inlet, make the air admission operator's compartment through purifying, and the filter material sheet is can peg graft to pack in the purifier shell, is convenient to change.
Embodiment of the present utility model is as shown in drawings:
Accompanying drawing is a kind of air purifier that square type interface is arranged, and its upper casing panel is made semi-sictional view.
Label among the figure is represented:
1, housing; 2, positive ventilation inlet; 3, side ventilation inlet; 4, nonwoven fabrics dedusting felt; 5, dedusting horse; 6, activated carbon fiber purifies sheet; 7, nonwoven fabrics felt; 8, metal gauze sheet; 9, housing interface board; 10, air outlet; 11, net sheet
Accompanying drawing is specified the utility model in conjunction with the embodiments:
The ventilation inlet 2 of the design's air purifier housing 1, air outlet 10 are square type air ports, are provided with net sheet 11, are provided with interface board 9 in the housing outer of air opening end and join with the air-conditioning ventilation inlet, can be provided with sealing elastic adhesive tape (figure part omitted) along interface board 9 places.On two side bodies of housing ventilation inlet, can establish side ventilation inlet 3, filter material in the housing can have two parts, set up separately by the stacked dedusting portion of nonwoven fabrics felt 4 at the air intake upstream portion, set up separately by the activated carbon fiber sheet at downstream portion and to purify the stacked air purification filter portion of sheet 6, the activated carbon fiber sheet purifies outside the sheet 6 can cover layer of non-woven fabric felt 7, and its outer folder by metal gauze sheet 8 is again established.Dedusting sheet 4 and purify on the sheet 6 and can establish horse 5 is located in the frame groove in the shell (among the figure mark) in order to insertion, so that change felt 4 and purify sheet 6.Purify sheet 6 and can be the W type and insert and be stacked and placed in the housing, only can leave less clearance between adjacent felt 4 and the purification sheet 6, fluffy felt fiber can be full of the gap.The excessive clearance of fibre plate 6 is in order to show the structure of monolithic among the figure, and the gap of actual device should be very little, to increase the air filtration clean-up effect.
Air-conditioning intake port shape according to different automobile types can be with the change of the design's housing inlet and outlet shape.
The using method of the design's cleaner be tipping at the air-conditioning ventilation inlet place of automobile, utilize after the suction of ventilating set makes air through this device filtration, purification in the car into the car, or the blast that heads on that produces when utilizing car to advance makes air through this device into the car.The dedusting portion of this device can be earlier with bulky grain dust absorption in the air again through purification portion, by activated carbon fiber with airborne hazardous and noxious substances, for example absorption such as 3.4-benzopyrene, hydrocarbons, oxides of nitrogen, foul smell.This kind fiber adsorption affinity is strong, and acid and alkali resistance is arranged, and the is heat-resisting chemical inertness of Denging, is not piled up light weight, and purification filtering is effective.And be to be plugged in the device case, be convenient to change.
