Detailed Description

Referring to fig. 1 and 2, the mask includes a mask body 1 and a fixing band provided on the mask body 1. The mask body 1 is provided with a cavity capable of accommodating mouth and nose, and the front end of the mask body 1 is provided with a filtering port 11 communicating the cavity with the outside. The cover body 1 is of a shell structure, and can keep the shape of the cover body, so that the mouth and the nose cannot be extruded in the cavity, and a wearer feels more comfortable.

The filter cover 2 is rotatably connected with the cover body 1 through a hinge shaft, the hinge shaft is arranged at the middle position of the lower part of the cover body 1, and the cover body 2 can cover the filter opening 11 of the cover body 1 or the filter cover 2 can be opened from the cover body 1 by rotating the filter cover 2. The middle position of the front end part of the filter cover 2 is provided with a hollow structure 21. Filter core 3 is placed in filter opening 11 department, strains lid 2 lid and closes the filter core 3 card between the cover body 1 and strain lid 2 when covering on the cover body 1, and hollow out construction 21 just in time faces filter core 3. Outside air loops through hollow out construction 21, filter core 3 and the cover body 1 filter orifice 11 and gets into the cover body 1 cavity in, and filter core 3 filters the air that gets into. The hollow structure 21 not only allows air to pass through, but also can block external liquid to prevent the liquid from directly spraying on the filter element 3, and meanwhile, can prevent the filter element 3 from falling out. The filtering port 11 of the cover body 1 is provided with a supporting bracket 13, and the supporting bracket 13 is integrally formed with the cover body 1 and is composed of 3 ribs. The support bracket 13 supports the filter element 3, fixes the filter element 3 together with the filter cover 2, and prevents the filter element 3 from entering the cavity of the cover body 1. In this embodiment, the cover body 1 and the filter cover 2 are both hard shell structures, the cover body 1 is made of ABS, and the filter cover 2 is made of PP.

The edge outside of cover body 1 rear end is equipped with round laminating shirt rim 4, and laminating shirt rim 4 is by soft sealing material preparation, preferably adopts the elastomer flexible glue, like silica gel, TPE and TPR etc. can paste on gauze mask wearer's face to it is sealed to form in laminating department. The air that the person of wearing breathes in all filters through filter core 3, has improved the filter effect of gauze mask greatly. The mask is well attached to the wearer, and the comfort of the wearer can be improved.

The cover body 1 is symmetrical left and right about a vertical plane, two lugs 12 are arranged on the outer wall of the cover body 1, the lugs 12 are provided with through holes, and the two lugs 12 are symmetrical about the symmetry plane of the cover body. The fixing strap has elasticity, including rear portion fixed band 51 and top fixed band, and the top fixed band includes two connecting bands 52 and two connecting portion 53, and two connecting portion 53 are connected respectively to the both ends of connecting band 52, and one end of rear portion fixed band 51 is connected with one of them connecting portion 53 of top fixed band after passing the through-hole on one lug 12, and the other end is connected with another connecting portion 53 of top fixed band after passing the through-hole on another lug 12. The back fixing belt 51 is used for being hooped at the back position of the head of a wearer, the two connecting belts 52 are used for being hooped at the top position of the head of the wearer, the tightening force is applied to the two lugs 12 which are bilaterally symmetrical, the force applied to the mask body is bilaterally symmetrical, and the back fixing belt 51 and the top fixing belt together enable the mask to be more firmly taken and are convenient to take on and take off; moreover, the rear fixing belt 51 and the top fixing belt are connected together, so that the length of the belt hooped on different parts of the head of a wearer can be adjusted, and the head of the wearer can adapt to various head types. Referring to fig. 3, the included angle a between the two connecting bands 52 and the same connecting portion 53 is 30-120 degrees, preferably 90 degrees, so that the two connecting bands 52 are properly separated to form tightening force at multiple positions, thereby making the mask more firm and stable to wear.

Referring to fig. 2, the filter cover 2 is provided with a lock 22, and the lock 22 is provided with a lock hole. The outer wall of the cover body 1 is provided with a convex buckle 14, the convex buckle 14 is arranged right above the vertical direction of the hinge shaft for connecting the filter cover 2 and the cover body 1, and the convex buckle 14 and a buckle hole on the buckle 22 can form buckle connection. The convex buckle 14 is connected with the lock buckle 22 together, so that the filter cover 2 can be fixed on the cover body 1, and the filter element is fixed between the filter cover 2 and the cover body 1; the filter cover 2 is opened to replace the filter cartridge by releasing the engagement of the male tab 14 with the button hole and separating the two by manually pulling the latch 22.

The cover body 1 is symmetrical left and right about a vertical plane, the lug 12, the support bracket 13 and the convex buckle 14 on the cover body 1 are symmetrical about the symmetrical plane of the cover body 1, and the filter cover 2, the hollow structure 21 and the lock catch 22 on the filter cover 2 are symmetrical about the symmetrical plane of the cover body 1. When wearing, the atress is even about the gauze mask, wears firmly, is difficult to produce the position dislocation, and the laminating shirt rim is better with the laminating of the person of wearing, and the gauze mask filter effect is better.

The utility model provides a gauze mask, the laminating shirt rim can form good laminating with wearer's face, and the air that the wearer was incoming call is all filtered through the filter core, has improved the filter effect of gauze mask greatly, has still improved wearer's comfort simultaneously.
