A medical mask

Abstract

The present invention relates to a medical mask. The present invention cleverly utilizes a partition to divide the mask body into two chambers, front and rear. The front chamber communicates with a rectangular cylinder, and the gas exhaled by the user gathers in the rear chamber and passes through the second chamber. The two-way gas check valve flows into the vertical air channel through the transition slide, and pushes the impeller blades under the turbine. The rotation of the turbine makes the air flow enter the circular pipe, and then flow out through the circular cutout to form a negative pressure in the cylinder. , forcing the outside air to enter the front chamber for accumulation under the action of air pressure, so that the user can smoothly absorb a sufficient amount of filtered air from the front chamber when inhaling, avoiding the occurrence of shortness of breath when the user breathes rapidly. In case of dyspnea, at the same time, the detachable filter screen replacement is realized by the cooperation of the slot and the bayonet pin on the rotary blocking plate, which is convenient and practical. The present invention has ingenious structure, convenient and simple use, and wide application range. It has strong practicability and is suitable for promotion and use.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, in particular to a medical mask. Background technique [0002] In order to prevent the infection of various infectious diseases and respiratory diseases, people's awareness of wearing masks in life and work has gradually increased, especially in order to improve the level of protection, wearing medical masks. [0003] Most of the existing masks have a single structure, and the whole mask is placed on the mouth and nose of the user, which has a certain impact on the breathing of the user, especially when the user is performing some intense sports or shortness of breath. The mask of the mouth and nose thus causes the occurrence of situations such as difficulty in breathing of the user, thereby causing certain potential safety hazards.

Problems solved by technology

[0003] Most of the existing masks have a single structure, and the whole mask is placed on the mouth and nose of the user, which has a certain impact on the breathing of the user, especially when the user is performing some intense sports or shortness of breath. The mask of the mouth and nose thus causes the occurrence of situations such as difficulty in breathing of the user, thereby causing certain potential safety hazards. Most masks have the problem of poor air permeability when inhaling, which makes it difficult for the user to inhale when inhaling. At the same time, for some filter element replacement masks, it is very troublesome to replace the filter screen, and it is difficult to replace the filter screen, which causes great inconvenience to the user. At the same time, when the mask is hung on the user's head According to different user groups, adaptive binding is carried out, so as to realize the adjustment of the hanging length. If the binding is too tight or too loose for different users, it will affect the user experience. Therefore, we urgently need a medical mask to solve the problem. above question
