To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1-2, a breathing mask capable of ventilating rapidly includes a casing 1 and a flexible member 2 disposed on the casing 1, a filter tip 3 is disposed on one side of the casing 1 away from the flexible member 2, a one-way breathing valve 4 is disposed above the filter tip 3, a breathing cavity 5 is disposed in the casing 1, guide assemblies 6 are symmetrically disposed in the breathing cavity 5, and the guide assemblies 6 are used for guiding exhaled waste gas to the one-way breathing valve 4.
The flexible part 2 comprises a V-shaped part and an inverted U-shaped part, the V-shaped part is used for fitting the mouth of a user, and the inverted U-shaped part is used for fitting the face of the user.
In this embodiment, this respirator and ordinary respirator wear the mode the same, all are provided with the fixed band that supplies to wear on casing 1. Through adopting the laminating of flexible member 2 and face, it is more comfortable to make to wear, through setting up V type portion and the type of falling U portion, makes the laminating of face guard and mouth and face tighter, avoids gaseous space inflow between flexible member 2 and the face. A replaceable filter layer is provided in the filter 3, and outside air is filtered while passing through the filter 3.
The venturi principle is characterized by the fact that the restricted flow has an increased flow velocity when passing through a reduced flow cross section, which is inversely proportional to the flow cross section. This scheme adopts the venturi principle, through setting up direction subassembly 6, leads to the exhaust gas of user's exhalation fast in one-way breather valve 4 to discharge exhaust gas through one-way breather valve 4, accomplish exhaled exhaust gas and fresh gas's replacement fast.
Specifically, the guide assembly 6 comprises a first guide plate 61 and a second guide plate 62, and a high-pressure airflow zone is formed between the first guide plate 61 and the second guide plate 62 and is used for rapidly guiding the exhaled waste gas to the one-way breather valve 4.
