Abstract
The utility model relates to a filter of a labor insurance mask. The filter of the labor insurance mask comprises a filter tank and a filter tank upper cover, the filter tank is made of aluminum alloy and comprises a tank upper face and a filter side face, the tank upper face of the filter tank is in a partial roof circular truncated cone shape, installation holes are formed in the tank upper face of the filter tank and are concentric with the tank upper face of the partial roof circle, and the circle center is located on the same plane. The tank upper face of the filter tank is designed to be in the partial roof circular truncated cone shape, so that ventilation resistance of the filter is reduced, a wearer breathes smoothly, the utilization efficiency of drugs is effectively improved, and the service life of the filter is prolonged.
Description
Technical field
The utility model relates to a kind of labour protection face shield device, particularly a kind of filter of labour protection face shield.
Background technology
Filtration members is the vitals of breathing mask, be mainly made up of the outer box of medicament and splendid attire medicament, and the box body of outer box affects the main performance of filtration members in a lot of degree.Current filtration members box body is on the market except CF is slightly distinguished, essential structure is almost just the same, is columniform main body and the circular end mostly, or the main body of prism and the polygonal end, on filter box, there is installing hole, in order to be connected with face shield.The filtration members aeration resistance of this design is larger, causes wearer to breathe and has some setbacks, and has reduced the utilization ratio of medicament simultaneously, thereby has shortened the service life of filtration members.
Utility model content
The utility model, for the deficiency of existing apparatus existence, proposes a kind of filter of labour protection face shield, and it can reduce air drag, improve medicament utilization rate;
The utility model solves existing issue by the following technical solutions;
A kind of filter of labour protection face shield, comprise filter box and Rose Box upper cover, described filter box is that aluminum alloy materials processing and manufacturing forms, filter box comprises above casing and filter side, it above the casing of described filter box, is inclined to one side top truncated cone-shaped, above the casing of described filter box, have installing hole, concentric above the casing of installing hole and above-mentioned inclined to one side tip circle, and the described center of circle is positioned at same plane;
Above described casing and between filter side, be also provided with fixed strip, the width of fixed strip is 2mm;
On the inside groove of described installing hole, be evenly provided with notch, the inner edge between the notch described in every two is provided with and links closely, and described installing hole is also connected with bracing frame, and described bracing frame is positioned at above the casing of filter box inner;
The number of described bracing frame is identical with the number of notch, and one end of bracing frame is connected with one end of notch respectively, and the other end of bracing frame is connected to each other, and form the summit of bracing frame, and the summit of this bracing frame is concentric with installing hole;
The cross section of the horizontal end of described bracing frame and perpendicular end is triangle;
The beneficial effects of the utility model: the utility model will be designed to inclined to one side top truncated cone-shaped above the casing of filter box, by such design, reduce the aeration resistance of filtration members, wearer is breathed smooth and easy, effectively improve the utilization ratio of medicament, thereby extended the service life of filtration members.
Brief description of the drawings
Fig. 1 is the top view of the utility model filter box;
Fig. 2 is the profile of the utility model filter box;
In figure, 1, filter side 2, filter end face 3, installing hole 4, bracing frame 5, inside groove 6, notch 7, link closely 8, bracing frame 9, fixed strip.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail;
A kind of filter of labour protection face shield, comprise filter box and Rose Box upper cover, described filter box is that aluminum alloy materials processing and manufacturing forms, filter box comprises above casing 2 and filter side 1, above the casing of described filter box, 2 is inclined to one side top truncated cone-shaped, above the casing of described filter box, have installing hole 3, above the casing of installing hole 3 and above-mentioned inclined to one side tip circle, 2 is concentric, and the described center of circle is positioned at same plane;
Above described casing 2 and filter side 1 between be also provided with fixed strip 9, the width of fixed strip is 2mm;
On the inside groove 5 of described installing hole 3, be evenly provided with notch 6, the inner edge between the notch 6 described in every two is provided with and links closely 7, and described installing hole 3 is also connected with bracing frame 8, and described bracing frame 8 is positioned at above the casing of filter box inner;
The number of described bracing frame 8 is identical with the number of notch 6, and bracing frame 8 one end are connected with one end of notch 6 respectively, and the other end of bracing frame 8 is connected to each other, and form the summit of bracing frame, and the summit of this bracing frame is concentric with installing hole;
The cross section of the horizontal end of described bracing frame 8 and perpendicular end is triangle;
The utility model, by being designed to inclined to one side top truncated cone-shaped above the casing of filter box, by such design, has reduced the aeration resistance of filtration members, wearer is breathed smooth and easy, has effectively improved the utilization ratio of medicament, thereby has extended the service life of filtration members;
Although described by reference to the accompanying drawings embodiment of the present utility model, in this area, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
