The embodiment of the application discloses a mask with good sealing performance.

Example 1:

referring to fig. 1 and 2, a mask with a good sealing property includes a mask body 1 designed to correspond to the contour of a human face, a fixing band 4 fixed to the mask body 1, and a filter cloth 5 fixed to the mask body 1. The cover body 1 is an elastic cover body 1 made of rubber; the front end of the cover body 1 is provided with a ventilation hole 11 in a penetrating way, and the filter cloth 5 is stuck and fixed on the cover body 1 and completely seals the ventilation hole 11; the fixed band 4 is including fixing two elasticity ropes in the cover body 1 both sides, and the both ends of elasticity rope are pasted respectively and are fixed in the upper and lower both sides of the cover body 1, and when wearing, the ear at the human body is hung to the elasticity rope.

The implementation principle of the embodiment 1 is as follows: through setting up the cover body 1 for the major structure of gauze mask can be better with the laminating of people's face, and then realize reliable sealed, inside and outside the gauze mask only can carry out gas exchange through seting up the venthole 11 on the cover body 1, and filter cloth 5 is fixed on the cover body 1 and seals venthole 11, and filter cloth 5 can effectual performance filtered air's effect.

Example 2:

referring to fig. 3, the present embodiment is different from embodiment 1 in that: the middle positions of the two elastic ropes are respectively fixedly stuck with a thorn wool belt 61 and a round wool belt 62.

The implementation principle of the embodiment 2 is as follows: the magic subsides connection structure that thorn hair area 61 and circle hair area 62 formed can be at the distance between two elastic rope of in-process adjustment of wearing the gauze mask, and then makes the inseparable wearing of gauze mask at facial, and the guarantee cover body 1 can closely laminate with facial, and then the closure of the guarantee cover body 1, the protective effect of guarantee gauze mask.

Example 3:

referring to fig. 4 and 5, the present embodiment is different from embodiment 2 in that: the fixing strap 4 comprises a neck hanging strap 42 fixed at the lower side of the mask body 1 and a head hanging strap 41 fixed at the upper side of the mask body 1; the ventilation hole 11 of the cover body 1 is provided with an internal thread sleeve 3 and an external thread sleeve 2.

The head hanging belt 41 and the neck hanging belt 42 are both elastic ropes with two ends respectively fixed on two sides of the cover body 1, the elastic ropes are disconnected from the middle position and detachably fixed together through a connecting assembly, and the connecting assembly is a magic tape connecting piece and comprises a round hair belt 62 and a thorn hair belt 61 which are respectively fixed on the two corresponding elastic ropes; 11 an organic whole of department of scavenge port is provided with hollow circular cylinder's external screw thread cover 2, and external screw thread cover 2 top spin has connect the internal screw thread cover 3 of cask form, and the blind end of internal screw thread cover 3 corresponds the coaxial through-hole that runs through of center on the external screw thread cover 2 and has seted up the through-hole, and 5 centre grippings of filter cloth are fixed between internal screw thread cover 3 and external screw thread cover 2, and the through-hole on internal screw thread cover 3 and the external screw thread cover 2 is constituteed scavenge port 11, external screw thread cover 2 is close to the coaxial sealed annular 21 of having seted up of one end terminal surface of filter cloth 5, the internal screw thread cover 3 is close to coaxially on the terminal surface of filter cloth 5 and has seted up and sealed annular 21 matched with sealing ring protruding 31.

Example 3 the example principle is: the head hanging belt 41 and the neck hanging belt 42 are respectively hung at the head part and the neck part, so that the tight feeling to the ears can be avoided while the mask body 1 is tightly fixed, and the comfort level of the mask when being worn is improved; the corresponding elastic ropes are detachably connected through the round wool belts 62 and the barbed wool belts 61, so that the elastic ropes are conveniently sleeved at the neck and the head; the filter cloth 5 can be relatively conveniently clamped and fixed between the internal thread sleeve 3 and the external thread sleeve 2.

Example 4:

referring to fig. 7 and 8, the present embodiment is different from embodiment 3 in that: the edge of the cover body 1 is bent and extended towards the inner side of the cover body to form a circular arc-shaped flexible welt 12.

The implementation principle of the embodiment 4 is as follows: the flexible welt 12 is arranged to optimize the elastic deformation performance of the edge of the cover body 1, so that when the edge of the cover body 1 is attached to a face, the edge can be smoothly deformed according to the outline of the face, and meanwhile, due to the deformation of the flexible welt 12, the cover body 1 and the face form face-to-face contact, and the sealing performance is enhanced; the flexible welt 12 can deform to a certain degree, so that the mask can be attached to the face more reliably when the mouth moves, the mask body is not easy to separate from the face, and the sealing property is guaranteed; meanwhile, the arc-shaped edge has better touch feeling and is more comfortable to wear.

Example 5:

referring to fig. 9 and 10, in order to better embody the structure of the mask body, the filter cloth structure is hidden in the drawing, and the difference between this embodiment and embodiment 4 is: the tip of the cover body 1 does not establish external thread cover 2 and internal thread cover 3 structure, and the cover body 1 is kept away from the integrative horn mouth section 13 that is provided with of one end of flexible welt 12, and the small-bore end of horn mouth section 13 and the cover body 1 fixed connection and with the scavenge port 11 intercommunication, filter cloth 5 pastes and fixes on the big-bore end terminal surface of horn mouth section 13 to accomplish the change of filter cloth through the mode of taking off used filter cloth and pasting new filter cloth. The upper end profile of the bell mouth section 13 inclines downwards to avoid the cover body shielding the sight when the mask is worn.

The implementation principle of the embodiment 5 is as follows: under the condition of the design of the main part edge mouth nose profile of the cover body 1 with the human face profile of inseparabler laminating, set up the flaring structure of horn mouth section 13 in the one end of the face of keeping away from in the cover body 1, the venthole 11 of the cover body is bigger and can the bigger filter cloth 5 of fixed area, and the area of taking a breath of gauze mask is bigger, can reduce the sense of suffocation in the gauze mask use.

Example 6:

referring to fig. 11 and 12, in order to better embody the structure of the cover body, the filter cloth structure is hidden in the drawing, and the difference between this embodiment and embodiment 5 is: the cover body 1 wholly sets up to loudspeaker form, and the little mouth end of the cover body 1 is the wearing mouth of bead nose profile design, and the heavy-calibre end of the cover body 1 is fixed with many support bars 7 that set up along vertical direction, and the upper and lower both sides edge at the cover body 1 heavy-calibre end is fixed respectively at the both ends of support bar 7, and support bar 7 is arc bending to keeping away from cover body 1 one side for fix filter cloth 5 on it and present the circular arc face form, improve the sight.

The implementation principle of the embodiment 6 is as follows: the cover body 1 is integrally arranged into a horn-shaped structure, so that demoulding is facilitated during injection molding production; the support bars 7 are arranged to support the large-caliber end structure of the cover body 1 and the filter cloth 5, so that the structural strength of the cover body 1 is enhanced, and the deformation is reduced; the supporting strips 7 support the filter cloth 5 to enable the filter cloth 5 to be in an arc surface state, the area of the filter cloth 5 is further increased, and meanwhile the overall appearance of the mask is optimized.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
