Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

With reference to fig. 1-4, the utility model relates to an air filter for gauze mask, including enclosing cover 1, filtration membrane 2 and base 3, enclosing cover 1 inside center is provided with conjunction 11, 3 central points of base put the connecting piece 31 that is provided with the pole type, filtration membrane 2 center is provided with through-hole 21, connecting piece 31 passes through-hole 21 with enclosing cover 1 central conjunction 11 is connected, base 3 is equipped with gas outlet 32, gas outlet 32 quilt filtration membrane 2 covers. In the using process, a proper position is reserved on the mask for preventing the filter, the base 3 is placed from inside, the side with the connecting piece 31 faces outwards, the connecting piece 31 penetrates through the through hole 21 on the filter membrane 2, and then the combining piece 11 on the outer cover 1 faces inwards to be combined with the connecting piece 31.

Wherein, base 3 outer fringe extends a spacing platform 33, 1 marginal outward extension of enclosing cover extends a location platform 12, location platform 12 corresponds with spacing platform 33 size on the base, mainly be for compressing tightly the gauze mask edge that the filter was installed when the block, make it be difficult for droing, and there is no longer than the gap between the spacing platform 33 block back on location platform 12 and the base 3, mainly be considered for some gauze masks except that there is the filter still to add the filter pulp piece when using, leave certain space and make even add the filter pulp piece filter also can the block.

As can be seen from fig. 4-5, the air outlet 32 on the base 3 is of a hub shape and is designed to be sunk, so that the filtering membrane 2 is not completely flat when being placed on the base 3, but is concave, so that when air is introduced from the air inlet 13, the air pushes the filtering membrane 2 against the base 3, the air inlet resistance is increased, the filtering effect is better, and when the air is exhaled, because the length of the combining part 11 is smaller than that of the connecting part 31, the edge of the filtering membrane 2 can be blown up by the air, the exhalation channel is larger, and the exhalation resistance is reduced.

It is to be noted that, in the description of the present application, the meaning of "a plurality" is two or more unless otherwise specified.

It is to be understood that the above description is intended to be illustrative, and not restrictive. Many embodiments and many applications other than the examples provided will be apparent to those of skill in the art upon reading the above description. The scope of the present teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are hereby incorporated by reference for all purposes. The omission in the foregoing claims of any aspect of subject matter that is disclosed herein is not intended to forego the subject matter and should not be construed as an admission that the applicant does not consider such subject matter to be part of the disclosed subject matter.
