The utility model has the advantages of simple structure, reasonable in design, can avoid that the prefiltering is cotton directly to be exposed in the air, directly block pollutants such as the aqueous vapor in the air, dust, paint outside the lid to the prevent pollution thing directly permeates and blocks up prefiltering cotton, extension protective face mask's life.
Description
Technical field
This utility model is related to protective articless field, and in particular to a kind of pre-filtering cotton fixing device of protective mast.
Background technology
It is existing with gas defence, the protective mast of dust reduction capability in, typically add pre-filtering cotton before the malicious box of filter, lead to
Pre-filtering cotton is crossed by particulate blockages such as spray painting, dust in outside, does not allow these granules to enter in the malicious box of filter, and existing pre- mistake
The lid that filter pulp is typically provided with through hole with center is fixed, positioned at through hole pre-filtering cotton directly it is exposed in atmosphere, in humidity
Under the working environments such as height, paint shop, exposed aerial pre-filtering cotton is easy to humidity, and the dust added in air is easy
Absorption easily causes pre-filtering cotton to block on pre-filtering cotton, and so as to increase the respiratory resistance of wearer, life-time service will cause
Protective mast fails.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above present in prior art, there is provided a kind of protective mast it is pre-
Filter cotton fixing device, pre-filtering cotton fixture structure is simple, reasonable in design for this, pre-filtering cotton can be avoided directly exposed in sky
In gas, the polluters such as aqueous vapor, dust, paint are blocked in outside fixing device.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of pre-filtering cotton fixing device of protective mast, including lid, lid top is evenly provided with multiple protective covers,
Multiple protective covers are surrounded with lid and are formed with air-vent；The protective sheet corresponding with ventilative hole shape, size is provided with lid, should
Protective sheet is used to blocking the rear of air-vent, and protective sheet mutually staggers in the axial direction with protective cover and is formed with gap, protective cover
It is connected with protective sheet by connecting portion, lid is connected by multiple support members with protective sheet.
Further improvement of the utility model is：Lid, protective cover, protective sheet, connecting portion and multiple support members are adopted
Identical material, is formed by integrated injection molding.
Further improvement of the utility model is：The axis of protective sheet and the axis of lid are in same longitudinal center line
On.
Further improvement of the utility model is：Lid outward flange is provided with outwardly projection.
The beneficial effects of the utility model are：This utility model is arranged on the pre-filtering cotton outside of the malicious box front end of filter, lid
Top is provided with protective cover and protective sheet for covering pre-filtering cotton, and protective sheet mutually staggers in the axial direction with protective cover
And gap is formed with, on the premise of not increasing respiratory resistance when in use, this utility model can avoid pre-filtering cotton directly naked
Pollutant in air in atmosphere, are directly blocked in lid outside, so as to preventing pollutant from directly permeating and blocking pre- by dew
Filter cotton, extends the service life of protective mast.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.
Referring to shown in accompanying drawing, a kind of pre-filtering cotton fixing device of protective mast of this utility model embodiment, the protection face
The pre-filtering cotton fixing device of cover is arranged on the pre-filtering cotton outside of the malicious box front end of filter, for covering pre-filtering cotton, it is to avoid pre- mistake
Filter pulp directly it is exposed in atmosphere.
A kind of pre-filtering cotton fixing device of protective mast of this utility model embodiment includes lid 1, and the top of lid 1 is uniform
Be provided with three protective covers 2, three protective covers 2 and lid 1 are around being formed with air-vent 3；It is provided with and the shape of air-vent 3 in lid 1
The corresponding protective sheet 4 of shape, size, the protective sheet 4 is used to block the rear of air-vent 3, in work such as humidity height, paint shops
Under environment, the pollutant in air can be directly blocked in the outside of lid 1 by the protective sheet 4, to prevent contaminant infiltration and block
Pre-filtering cotton, protective sheet 4 mutually staggers in the axial direction and is formed with gap with protective cover 2, and air enters protective sheet from air-vent 3
4 and the gap of protective cover 2, and then ensure can be empty from the breathing of the gap location of protective sheet 4 and protective cover 2 when using protective mast
Gas, protective cover 2 is connected by connecting portion 5 with protective sheet 4, and lid 1 is connected by multiple support members 6 with protective sheet 4, connecting portion 5
With support member 6 while interconnection function is played, the gap between protective sheet 4 and protective cover 2 is also maintained, to ensure using anti-
Smooth breathing can be kept during face shield.
