Description
Technical Field
The utility model belongs to the technical field of protective articles, especially, relate to a filter element protection box.
Background
At present, when an enterprise producing respiratory protection articles produces respiratory protection filter elements for coal mine underground operators, the enterprise focuses on how to improve raw materials, formulas and manufacturing processes of the filter elements so as to improve the respiratory protection time, and neglects the influence of the coal mine underground working environment on the respiratory protection time. However, underground water spraying and coal mine slurry splashing frequently occur due to the underground working environment of the coal mine, and the underground damp and splashing environment of the coal mine has influence on the filter element, so that the respiratory protection time is reduced.
Most of the traditional domestic respiratory mask filter elements are single filter elements, no protective device is arranged outside the filter elements, and the filter elements do not have a waterproof function. However, the water spraying and dust settling procedures are set just in the underground operation of the coal mine, and coal mine slurry splashes onto the filter element at times in the underground mining process, and the moist operation environment and the coal mine slurry splash are main reasons for reducing the protection efficiency of the filter element. At present, a protection box for protecting a filter element is formed by assembling a plurality of parts, and the protection box needs to be assembled before being used, so that the protection box is troublesome and wastes time; meanwhile, the air suction hole is blocked, so that the user cannot breathe smoothly.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a filter element protects box can effectually be waterproof, prevent mud splash to do not influence filter element's air permeability, improve filter element guard time and availability factor in the pit in the colliery greatly.
A filter element protection box is a truncated cone-shaped cover body which is made of PP plastics and provided with edges, and comprises a truncated cone-shaped protection box main body, wherein the edges are vertically arranged on the outermost edges of the bottom surface of the protection box main body; the middle part of the protection box main body is provided with an inwards concave vent groove, and the side surface of the vent groove is provided with vent holes for ventilation along the circumferential direction; frameworks with different lengths are arranged in the protection box main body; the edge of the protection box main body is inwards provided with a limiting bulge protruding out of the bottom surface of the edge.
The framework is arranged in the protective box in a radial mode by taking the axis of the vent groove as the center.
The utility model has the advantages that: the utility model is formed in one step, the work is simpler, and the secondary assembly is not needed when in use; the air vent in this application directly communicates with each other filter element and outside, and the air vent does not have the shelter from, does not have the resistance of breathing in, makes the person of wearing breathe in more smoothly.

Detailed Description
For better explanation of the present invention, the following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings for better understanding.
A filter element protection box is a truncated cone-shaped cover body which is made of PP plastics and provided with edges 2, and comprises a truncated cone-shaped protection box main body 1, wherein the edges 2 are vertically arranged at the outermost edges of the bottom surface of the protection box main body 1; the protection box comprises a protection box body 1 and is characterized in that an inwards concave vent groove 3 is formed in the middle of the protection box body 1, vent holes 4 used for ventilation are formed in the side faces of the vent groove 3 along the circumferential direction, the inside of the protection box is communicated with the external environment through the vent holes 4, and a wearer wearing a protection filter element can breathe more smoothly. The protective box body 1 is internally provided with frameworks 5 with different lengths, so that a supporting effect is achieved; the framework 5 is arranged in the protective box in a radial manner by taking the axis of the vent groove 3 as the center; the edge 2 of the protection box main body 1 is inwards provided with a limiting bulge 6 protruding out of the bottom surface of the edge 2 and used for fixing the filter element inside the protection box, and the limiting bulge 6, the edge 2 of the protection box and the bottom surface of the protection box main body 1 form a space capable of containing the filter element and used for placing and fixing the filter element.
Preferably, the frameworks 5 are alternately arranged in length, and the short frameworks 5 are arranged around the vent groove 3.
The working principle of the filter element protection box is as follows: the utility model blocks the spraying water and the slurry in a physical isolation way, so that the surface of the filter element is kept clean, and the service life of the filter element is prolonged; meanwhile, the front of the vent hole 4 is not shielded and is directly communicated with the outside, so that the user can breathe smoothly.
Before wearing, be connected protection box and filter element earlier, install filter element inside the protection box, fixed filter element with spacing arch 6, the filter element protection box that will connect is whole again, is connected to half face guard on.
