Abstract
The utility model discloses an air filtering device. The air filtering device comprises an activated carbon tank, a mounting seat and an air filter, wherein the mounting seat is arranged on the activated carbon tank and is connected with the air filter. The device is characterized in that: an ambient air channel, a clean air channel and an exhaust channel are formed in the mounting seat; the ambient air channel is used for directly conveying air from which only steam and dust are filtered to a sensor for detection; the clean air channel generates clean air by using activated carbon and filtering materials in the filtering device to clean the sensor which can be polluted by volatile organic matters; and the exhaust channel is used for exhausting inlet air of the two channels. Due to the adoption of a cleaning device with the sensor, the provided filtering device can filter the volatile organic matters in the air to continuously provide the clean air and clean the sensor. The air filtering device has a simple structure and is convenient to use.
Description
Technical field
The utility model relates to air filter, more particularly, relates to a kind of place that is applied to exist harmful escaping gases such as benzene, for removing VOC in the air in the VOC detector, the air filter of clean air is provided.
Background technology
At present, existing on the market VOC detector is after the medium-term and long-term operation of working environment, and sensor can be polluted by the residual dirt of escaping gas, thereby influences accuracy of detection, even the phenomenon that false alarm occurs or do not report to the police, and then causes the generation of accident.The defective value of said prior art must improve.
The utility model content
The purpose of the utility model is to above-mentioned technological deficiency a kind of air filter to be provided.This a kind of air filter adopts and carries the sensors clean device, the organic volatile of the filter of outfit in can filtered air.
The utility model solves the technical scheme that its technical problem adopted: a kind of air filter; Comprise activated carbon canister, mount pad and air cleaner; Said mount pad is installed on the activated carbon canister; This mount pad also is connected with air cleaner, and its special card is to be provided with surrounding air passage, clean air passage and exhaust passage in the said mount pad.
The air that said surrounding air passage will only filter aqueous vapor and dust directly is delivered to sensor and detects; The clean air passage utilizes activated carbon and the filtering material in the filter, and the air that produces cleaning is used to clean maybe be by the sensor of volatile organic matter pollution; The air inlet of preceding two passages is discharged in the exhaust passage.
According to the utility model of said structure, its beneficial effect is, the utility model adopts and carries the sensors clean device, and the organic volatile of the filter of outfit in can filtered air provides to continue clean air cleaning sensor.The utility model is simple in structure, and is easy to use.

Fig. 2 is the utility model structure explosive view;
Fig. 3 is the utility model structural representation.
Activated carbon canister in the drawings, 1; 2, air cleaner; 3, surrounding air passage; 4, clean air passage; 5, exhaust passage; 6, filter core; 7, flame proof sheet; 8, mount pad.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Like Fig. 1-shown in Figure 3; A kind of air filter; Comprise activated carbon canister 1, mount pad 8 and air cleaner 2; Said mount pad 8 is installed on the activated carbon canister 1, and this mount pad 8 also is connected with air cleaner, is provided with surrounding air passage 3, clean air passage 4 and exhaust passage 5 in the said mount pad 8.
The air that said surrounding air passage 3 will only filter aqueous vapor and dust directly is delivered to sensor and detects; Clean air passage 4 utilizes activated carbon and the filtering material in the filter, and the air that produces cleaning is used to clean maybe be by the sensor of volatile organic matter pollution; The air inlet of preceding two passages is discharged in exhaust passage 5.
