Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to an oxygen supply breathing mask. Background Art

[0002] An oxygen mask is a device that transfers oxygen from a storage tank to the human lungs. The oxygen mask can cover the nose and mouth (oral nasal mask) or the entire face (full face mask), and plays an important role in ensuring human health and safety.

[0003] However, in actual use, it still has some disadvantages. For example, when the current breathing mask is clamped and worn, the side walls of the mask opening are in direct contact with the mouth and nose of the human face. Since the side walls are relatively narrow, the pressure between the side walls of the mask and the face will be too high when worn tightly, which can easily affect the wearer's comfort. At the same time, since the side walls are relatively fixed, they cannot effectively fit the wearer's face, forming a relatively closed space, which leads to excessive connectivity between the mask and the outside world, thereby affecting the oxygen supply effect itself.

[0004] In view of the existing structure and defects, improvements are made to provide an oxygen supply breathing mask in order to achieve a more practical purpose. Utility Model Content

[0015] (3) Beneficial effects

[0016] The utility model provides an oxygen supply breathing mask, which has the following beneficial effects:

[0017] (1) The utility model sets an oxygen mask base, a fixed cover and a shrinkage notch, and utilizes the cooperation of the plurality of them. The operator fastens the oxygen mask base as a whole to the breathing part of the face through the fixed cover, and at the same time, the two elastic ropes are fixed to the two ends of the mandible through a slipknot. At this time, the fixed cover has an elastic effect as a whole, which causes a deformation effect, so that one side of the fixed cover can fit to the surface of the oxygen mask base according to the contour shape of the human face. At the same time, the trapezoidal structure of the fixed cover is used to tilt the side close to the face skin inward, thereby achieving the purpose of shrinkage and fixation, so that the fixed cover is close to the face skin. One side of the face can fit tightly against the skin surface to ensure that there are no large gaps on its surface. At the same time, the two ends of the elastic locking rope are passed through the fixed slots in the fixed top plate, wrapped around and fixed to the surface of the fixed top plate, and fixed by friction with the inclined strips. The pressure generated by the contraction of the elastic locking rope is used to continuously compress the peripheral side of the fixed cover, so that the contraction slots on the inside contract toward the inner side of the fixed cover, further controlling the overall inward tilt and shrinkage of the fixed cover, and further ensuring the contact effect between the side of the fixed cover and the skin, thereby ensuring its overall airtightness.

[0018] (2) The present invention provides an elastic locking rope, an elastic rope and a fixed top plate, and utilizes the cooperation of the elastic locking rope and the fixed top plate to ensure that the operator wears the oxygen mask firmly more conveniently and quickly. The elastic locking rope can be used to squeeze and deform the outer side of the fixed mask so that it fits the facial shape of different wearers and makes its structure ergonomic, thereby improving the scope of use of the device and reducing the impact of individual differences in use.

An arc-shaped groove 6 is provided on one side of the surface of the fixing cover 5, and an elastic locking rope 7 is slidably embedded in the surface of the arc-shaped groove 6. Contraction grooves 8 are equidistantly provided on the upper and lower surfaces of the fixing cover 5 along the inner side thereof. An embedding sealing groove 9 is provided on the side of the fixing cover 5 close to the oxygen mask base 1. The fixing cover 5 is seamlessly embedded with the side of the oxygen mask base 1 through the embedding sealing groove 9, and the top end of the elastic locking rope 7 is slidably embedded in a fixed top plate 10, and the two ends of the fixed top plate 10 are provided with rounded corners.

[0027] The fixed top plate 10 has fixed notches 11 on both sides of its surface, and inclined stripes 12 on its upper and lower surfaces. The two ends of the elastic locking rope 7 pass through the two inclined stripes 12 on the surface of the fixed top plate 10 respectively. The elastic locking rope 7 is made of rubber material as a whole. The length of the elastic rope 3 ranges from ten centimeters to fifteen centimeters, and one end of the elastic rope 3 extends to the interior of the oxygen mask base 1. The surface of the elastic rope 3 is set to a rough surface structure. The elastic rope 3 The other end of the oxygen mask is wrapped and fixed with a counterweight 14, which is made of cotton material and is in the shape of a long strip. A fixed arc cavity 13 is provided inside the oxygen mask base 1, and the fixed arc cavity 13 is raised on the side away from the fixed cover 5 to form an arc surface structure. The shape of the elastic locking rope 7 is adapted to the outer contour of the arc groove 6, and the cross-section of the arc groove 6 is semicircular, and the depth of the arc groove 6 is half of the diameter range of the elastic locking rope 7.

[0028] For details, please refer to the attached manual Figure 1-4The entire material of the fixed cover 5 is elastic material, and the cross-section of the fixed cover 5 is trapezoidal. The contraction groove 8 is arranged close to the inner side surface of the fixed cover 5 and passes through one side surface of the fixed cover 5. The depth value of the contraction groove 8 is one-half to one-third of the thickness value of the fixed cover 5, and the cross-section shape of the contraction groove 8 is rectangular.

[0029] The specific implementation method is as follows: the entire material of the fixed cover 5 is an elastic material, and the cross-section of the fixed cover 5 is trapezoidal, so that one side of the fixed cover 5 can be attached to the surface of the oxygen mask base 1, and at the same time, the trapezoidal structure is used to make the side close to the face skin tilt inward, thereby achieving the purpose of contraction and fixation, so that the side of the fixed cover 5 close to the face can fit tightly with the skin surface, ensuring that there are no large gaps on its surface, thereby fully ensuring the overall gas transmission work of the oxygen mask base 1.

[0030] The working principle of this utility model:

[0031] Step 1: First, the operator assembles the various components of the device normally, and then starts the device normally.

[0032] Step 2: First, the operator fastens the oxygen mask base 1 as a whole to the breathing part of the face through the fixed cover 5, and at the same time, the two elastic ropes 3 are fixed to the two ends of the mandible through a slipknot. At this time, the fixed cover 5 has an elastic and deformable effect, so that one side of the fixed cover 5 can fit to the surface of the oxygen mask base 1 according to the contour shape of the human face. At the same time, the trapezoidal structure of the fixed cover 5 is used to tilt the side close to the face skin inward, thereby achieving the purpose of contraction and fixation, so that the side of the fixed cover 5 close to the face can fit tightly with the skin surface to ensure that there is no large gap on its surface. At the same time, the two ends of the elastic locking rope 7 are passed through the fixed slots 11 in the fixed top plate 10, and are wrapped and fixed to the surface of the fixed top plate 10, and are fixed by friction with the inclined strips 12. The pressure generated by the contraction of the elastic locking rope 7 is used to continuously press the peripheral side of the fixed cover 5, so that the contraction slots 8 on the inner side contract toward the inner side of the fixed cover 5, and further control the fixed cover 5 to tilt and shrink inward as a whole, thereby further ensuring the contact effect between the side of the fixed cover 5 and the skin, thereby ensuring its overall airtightness. Finally, the device completes the wearing of the oxygen mask base 1 and the subsequent oxygen supply work.

[0033] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
