Embodiment 1

[0034] In some dusty and smoggy weather, the air is mostly polluted particles with larger diameters, and there are no harmful substances such as viruses and bacteria, the user can remove the filter slot cover and the mask filter element on the mask when wearing the mask. , the activated carbon fiber layer and filter cotton layer inside and outside the breathing layer can filter the current situation, and when the breathing chamber isolates the mouth and nose from the outside world, it ensures that the air that the user breathes passes through the breathing layer of the mask filtered gas. When the mask can achieve the effect of preventing dust and haze, removing the filter tip slot cover and the mask filter element can also ensure the user's breathing comfort without breathing effort.

Embodiment 2

[0036] In some specific occasions, such as hospital places, next to infectious patients, or areas with frequent infectious disease outbreaks, where there are a lot of viruses and bacteria, users should add filter slot covers and mask filter elements when wearing masks, and can adjust according to actual conditions. Choose different combinations of mask filter elements to ensure the filtering strength of the mask. When the mask filter element loses its service life, the mask filter element can be replaced through the detachable feature of the filter tip device, and the filter tip device can be properly sterilized. Even in the occasions where bacteria and viruses occur frequently, it can also achieve safe filtration and free breathing. Avoid the risk of infection.

[0037] In the present invention, a replaceable mask filter element is only arranged in the middle part of the mask body, and the mask filter element is one of activated carbon fiber layer, cotton bamboo fiber layer, ...

Abstract

The invention relates to a protective mask with a detachable filter tip. The mask comprises a mask body, ear bands are symmetrically arranged at the two ends of the mask body. A breathing layer is arranged in the middle of the mask body; the outer surface of the mask body is covered with a breathing layer and provided with a filter tip device, the inner surface, corresponding to the filter tip device, of the mask body is provided with an annularly-sealed breathing cavity in a protruding mode, the filter tip device comprises a filter tip fixing frame and a filter tip groove cover, and a plurality of mask filter elements are arranged in the filter tip groove cover and surround the breathing layer to be integrally formed with the mask body. The replaceable mask filter element is only arrangedin the middle of the mask body and is formed by combining and processing one or more of the activated carbon fiber layer, the cotton bamboo fiber layer, the polymer fiber layer, the acupuncture cotton layer, the melt-blown fabric layer and the non-woven fabric layer, the mask filter element can be replaced according to different occasions, and the application range is wide; the protruding breathing cavity is formed in the inner surface of the mask body and can be tightly attached to the face, and the situations of local air leakage and poor filtering effect caused by insufficient sealing performance of a traditional mask are avoided.

Description

technical field [0001] The invention relates to a filter-tip detachable protective mask, which belongs to the technical field of medical equipment. Background technique [0002] Masks are used as protective equipment in daily life and have been applied in many occasions. Wearing a mask in a timely manner can reduce the inhalation of some harmful gases and particles, such as catkins, catkins and dust in the air, especially when encountering some smog and dust weather, masks can play a certain role. protective effect.
