Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the existing integrated floating and diving mask is also the most common integrated floating and diving mask structure in the field, and includes an inner cover 101 and an at least partially transparent outer cover 100, where the outer cover 100 includes lenses, the inner cover 101 separates the outer cover 100 into an upper chamber and a lower chamber through a partition 102, the upper chamber is communicated with an air intake channel, the lower chamber is communicated with an exhaust channel, the inner cover 101 is provided with at least one unidirectional air intake structure 103, air enters the upper chamber through the air intake channel, and enters the lower chamber through the unidirectional air intake structure 103 to be inhaled by a floating and diving person, and the unidirectional air intake structure 103 cannot ensure that the exhaled air does not flow backwards, so that fogging on the lenses is still easily caused.
The invention carries out modification design on a one-way air inlet structure of the integrated floating and diving mask, as shown in fig. 2-6, the one-way air inlet structure comprises an air inlet support and an elastic sheet 5, the air inlet support comprises a body 2 forming an air inlet channel, the body 2 comprises an annular seat 1 extending along an air inlet direction and a fixing part 4 used for fixing the elastic sheet 5 on the body 2, the elastic sheet 5 is matched with the annular seat 1 to realize the opening or closing of the air inlet channel, and the elastic sheet 5 extends from the fixing part 4 to the annular seat 1 towards the air inlet direction, so that the elastic sheet 5 and the body 2 form a certain inclination angle. The existing elastic sheet is generally arranged in parallel with the body of the air inlet structure, the air inlet structure adopts a certain inclination angle arrangement, so that the absolute length of the elastic sheet 5 is longer than that of the parallel arrangement, the force arm is increased, meanwhile, the elastic sheet 5 is inclined along the air inlet direction, the elastic sheet 5 can be opened only by small air pressure, and the air inlet is easier, as shown in figure 4.
Further, a first stopper 3 is provided upstream of the elastic sheet 5, and the first stopper 3 prevents the elastic sheet 5 from being excessively deformed. As shown in fig. 5, when exhaling, the elastic sheet 5 is easily bent and deformed toward the air inlet, and when the pressure in the lower cavity is too high, the elastic sheet 5 is easily bent excessively, so that the elastic sheet 5 is separated from the annular seat 1, and this phenomenon can be effectively prevented by the arrangement of the first blocking portion 3. Preferably, the first blocking portion 3 is a filter screen, so as to filter partial impurities in the air intake process and play a role in blocking in the air exhaust process.
Of course, the first stopper 3 may not be provided, and the elastic sheet 5 may be limited, for example, the elastic sheet 5 may be provided as follows: when the elastic piece 5 is deformed toward the air inlet, the elastic piece 5 is always in contact with the annular seat 1 (backflow is prevented). Preferably, when the elastic piece 5 is in the maximum deformation state, the distance from the contact portion 7 of the elastic piece 5 and the annular seat 1 to the free end tip of the elastic piece 5 is L, L >0, as shown in fig. 6, that is, the deformation amount of the elastic piece 5 toward the air inlet is limited by the processing means.
Further, the annular seat 1 comprises a conical surface structure 6, and the conical surface structure 6 is matched with the elastic sheet 5.
Further, the elastic sheet 5 is made of rubber.
As shown in fig. 7-12, the present invention provides another unidirectional air intake structure for an integrated snorkel mask, which is different from the unidirectional air intake structure shown in fig. 2-6 in the structure of the elastic sheet 5 and the matching structure of the elastic sheet 5 and the annular seat 1. Specifically, the elastic piece 5 extends from the fixing portion 4 toward the annular seat 1 in the air intake direction, so that the elastic piece 5 and the body 2 form a certain inclination angle. The elastic sheet 5 comprises a deformation part 51 and a sliding part 53, the sliding part 53 is connected with the deformation part 51 through a bending part 52, the deformation part 51 and the sliding part 53 extend from the bending part 52 towards the air inlet direction to two sides, the sliding part 53 is of an annular structure, at least one air hole 54 for air inlet is arranged on the sliding part 53, and the bending deformation of the deformation part 51 drives the sliding part 53 to slide on a conical surface 55 of the annular seat 1 so as to open or close the air hole 54. With the above arrangement, when air is sucked, the sliding portion 53 slides along the tapered surface 55 by the bending deformation of the deformation portion 51, and the air vent 54 is opened, so that air is easily sucked, as shown in fig. 8. During exhalation, the deformation portion 51 deforms toward the air inlet, the bending portion 52 also moves toward the air inlet, so as to drive the sliding portion 53 to slide upwards along the tapered surface 55, and the air holes 54 always move in the closing direction, as shown in fig. 10-11, so as to prevent backflow and fogging. Even if the sliding portion 53 slightly pivots about the bent portion 52 as a fulcrum when the expiratory pressure is further increased so that the deformation amount of the deformable portion 51 is further increased, the sliding portion 53 still maintains a contact state (contact point 57) with the tapered surface 55, and the reverse fogging can be effectively prevented, as shown in fig. 12.
Further, the deformation portion 51 is bent in the air intake direction in a free state, so that the elastic piece 5 is more easily deformed at the time of air intake, thereby more easily bringing the sliding portion 53 into motion.
Further, the sliding portion 53 is made of an undeformable material, and the deforming portion 51 is made of an elastic rubber material.
The invention also provides a method for preventing the lens of the snorkeling mask from being atomized, and particularly, by adopting the one-way air inlet structure, when air is sucked, air enters the upper cavity and acts on the elastic sheet 5, the deformation part 51 of the elastic sheet 5 bends and deforms to drive the sliding part 53 to slide downwards on the conical surface 55 of the annular seat 1, the air hole 54 is opened, and the air enters the lower cavity for a snorkel to suck; when the patient exhales, air acts on the elastic sheet 5, the deformation part 51 of the elastic sheet 5 bends and deforms to drive the sliding part 53 to slide upwards on the conical surface 55 of the annular seat 1, the air holes 54 are closed, and the exhaled air cannot enter the upper cavity, so that atomization is prevented.
The above examples are only for illustrating the technical solutions of the present invention, and are not limited thereto. Although the invention has been described in detail with respect to the specific embodiments and general description, it will be apparent to those skilled in the art that many modifications and improvements can be made to the invention or equivalents may be substituted for elements thereof. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
