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 t

Embodiment 1

[0037] Embodiment one, combined with the attached Figure 1-18, a medical mask, comprising a transparent mask body 1, the transparent mask body 1 can see the breathing situation inside the mask body 1 from the outside, it is characterized in that the front end of the mask body 1 communicates with a cylinder 2, the circular cylinder 2 Both ends of the cylinder 2 are open, and a vertical partition 3 is connected inside the cover body 1 to divide the inside of the cover body 1 into two chambers, the front chamber 4 and the rear chamber 5, respectively. The front chamber 4 communicates with the cylinder 2, the rear chamber 5 fits the face of the user, and the rear end of the partition 3 is connected to a horizontally arranged baffle 6 to divide the rear chamber 5 There are two upper and lower layers, and there are multiple groups of first gas one-way valves 7 used to flow gas from the front side chamber 4 to the back side chamber 5 connected to the partition plate 3, and the first...

Embodiment 2

[0040] Embodiment two, on the basis of embodiment one, in conjunction with the attached Figure 1-18 , the filter screen replacement structure 17 includes an annular blocking plate 20, the middle part of which is open in the shape of an annular structure, and the blocking plate 20 is provided with an annular groove matching the cylinder 2 21, satisfying that the blocking plate 20 can be set on the cylinder 2 through the annular groove 21, and the end of the cylinder 2 is inserted into the annular groove 21 to realize the fitting effect between the blocking plate 20 and the cylinder 2. The annular groove 21 is axially slid to fit an annular transition plate 22, the size of the transition plate 22 just matches the size of the annular groove 21, and a set of springs set in the annular groove 21 is connected between the bottom of the annular groove 21 and the transition plate 22 23. The outer circumference of the cylinder 2 is uniformly connected with multiple groups of bayonet pi...

Embodiment 3

[0041] Embodiment three, on the basis of embodiment one, in conjunction with the attached Figure 1-18 The screen changing structure 18 includes a rectangular frame 27 set on the lower end of the rectangular tube 8, the size of the rectangular frame 27 is just enough to be set on the lower end of the rectangular tube 8, and the lower end of the rectangular frame 27 is connected with the lower end of the rectangular tube 8. Clamp the rectangular baffle plate 28 of the filter screen 19, the size of the rectangular baffle plate 28 is smaller than the size of the rectangular frame 27, the outer wall of the rectangular cylinder 8 has a rectangular groove 29 along the four sides, the inner side of the rectangular frame 27 The rubber ring 30 that cooperates with the rectangular groove 29 is connected around the wall. There are arc-shaped clamping grooves 31 on the left and right side walls outside the rectangular frame 27. The clamping groove 31 is convenient for the user to overcome ...

Abstract

The invention relates to a medical mask. A mask body is divided into a front cavity and a rear cavity by ingeniously utilizing a partition plate, a rectangular cylinder communicates with the inside ofthe front cavity, air exhaled by a user is gathered in the rear cavity and then flows into a vertical air duct through a second air one-way valve via a transition slide way, a pushing blade below a turbine is pushed, the turbine rotates to enable airflow to enter an annular pipeline, then the airflow flows out through an annular notch and then negative pressure is formed in the cylinder, externalair is forced to enter the front cavity under the action of air pressure to be gathered, so that the user can smoothly inhale sufficient filtered air from the front cavity during inspiration, and thecircumstance of dyspnea occurring when the user breathes rapidly is avoided. Meanwhile, a detachable filter screen is replaced by cooperation of a clamping groove in a rotary plugging plate and a clamping pin, and the medical mask is convenient and practical. The medical mask is ingenious in structure, convenient and simple to use, wide in application range, high in practicability and suitable for popularization 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. 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 som...
