Abstract
The utility model relates to an air curtain dust-filtering respiration protector, comprising a casing. A miniature electric fan is arranged in the casing. A filter box is arranged in front of the air inlet of the rear part of the casing. The air outlet of the front part of the casing is vertical to the casing. When used, the air curtain dust-filtering respiration protector is worn at the front part of a head by lace fastening. After the air curtain dust-filtering respiration protector is started, dust-laden air is inhaled from the air inlet and passes through the filter box for dust filtration. Clean air which is blown out forms an air flow (air curtain) in front of faces. Air inhaled by workers wearing the utility model is the clean air in the air curtain. A wind shielding face mask has an auxiliary wind shielding effect. The utility model has the advantages of fluent respiration, the function of reducing temperature, and a dust-proof function for eyes.
Description
The utility model relates to the dustproof utensil of a kind of individual, particularly a kind of air curtain formula dust-filtering respirator.
Dust work personnel personal protection now, when dust concentration is low or higher, adopt filter-type respirator, nose cup or powered air-purifying formula anti-dust respirator, the helmet etc., filter-type respirator, nose cup more, need be worn over snout, inconvenience is arranged, and respiratory resistance is big, especially in summer and high-temperature dust operation place, easily perspire, do not have cooling effect, the workman is reluctant to wear, and eyes are not had dustproof effect.Also there are tight cover portion in powered air-purifying formula anti-dust respirator, the helmet, carry inconvenience, and volume is big, the shortcoming of no cooling effect.
The purpose of this utility model provides a kind of dust concentration when higher, the air curtain formula dust-filtering respirator that uses when being particularly suitable for the summer high temperature operation.
The novel housing that comprises of this use, housing is provided with frenulum, is provided with the miniature electric blower fan in the housing, and housing is " " shape, is provided with filter cartridge before the air inlet of housing rear portion, and the air outlet of housing front portion is vertical with housing.The course of work is as follows, this device is worn by frenulum and is equipped with in forehead and head front portion, opening power, start micromachine, drive centrifugal fan, extraneous dust laden air is sucked, filter the dirt filtration of material after filtration in the box, air is purified, and blows under forehead is vertical by air outlet then, form one at face certain speed, width are arranged, the pure air stream (being air curtain) of thickness covers whole breathing zone, when the workman is air-breathing, directly suck the pure air in the air curtain, and can play cooling and the dustproof effect of eyes.
Big and when splashing as wind or dust granules, can set up hurricane globe, make outside dust can't penetrate air curtain, and do not sucked, and play the facial thermal-radiating effect that prevents by the workman.
The utility model is worn comfortable, breathes smoothly, and snout does not have compressing, and volume is little, and is in light weight, and cooling effect is arranged, and plays the dustproof effect of entire face, and cost is lower, can with miners' cap, welders' mask and other relevant safety device combinations.
With reference to the accompanying drawings the utility model is elaborated below.
Accompanying drawing is the utility model structural representation
With reference to accompanying drawing, one light, thin, solid plastics or metal shell [1], inner air channel is reasonable, be made into concave surface with the head junction, subsides are with flexible material, coincide with head, comfortable, closely, internal fixation miniature electric blower fan [4] (employing centrifugal fan), can adopt fire-proof motor in case of necessity, at the preceding filter cartridge [2] of establishing of air inlet [3], filter dirt material can adopt no gauze or polyamide fibre fine fibre to add Coarse Mesh Gauze filtrate etc. in the filter cartridge, filter cartridge can adopt and snap in or insert on the air inlet place casing, be beneficial to change filtrate and cleaning, the preceding hurricane globe [7] that is provided with of air outlet [6], complete machine is fixed in the frons and the top of the head by frenulum [5].
