Description

Technical Field

[0001] The invention relates to the technical field of breathing masks, and in particular to a high-sealing breathing mask that can be quickly put on and taken off. Background Art

[0002] A breathing mask is a special breathing device that protects the human respiratory organs from being harmed by toxic gases from the outside world. It removes toxic and harmful gases such as organic vapor, inorganic, acidic gases, ammonia, steam, smoke, etc. through adsorption, absorption, catalysis and direct filtration of filtering devices. It is used by industrial and mining enterprise personnel in an oxygen-free environment.

[0003] The respiratory mask is mainly composed of a mask body and a sealing elastic body. The mask body is provided with corresponding air inlet and outlet, and corresponding wearing ropes are connected to the upper and lower sides of the mask body for wearing. Since the sealing elastic body that fits the face is made of flexible material, under the force of the two pulling points of the wearing rope arranged at intervals above and below the mask body, the elastic body located between the pulling points is prone to bulge outwards due to the force, which affects the sealing of the respiratory mask when worn. If the two pulling points are brought close together, it will affect the uniformity of the overall force of the respiratory mask, as well as the wearing stability and overall tightness.

[0004] Furthermore, the breathing mask is mainly used to connect the ends of the wearing rope and adjust the length through the adjustment buckle set on the wearing rope, so as to adjust the tightness to fix and remove the breathing mask. Every time the mask is removed, it is necessary to stretch and loosen the wearing rope, or the buckle and regulator of the adjustment buckle need to be removed. However, the adjustment buckle is mainly installed at the back of the head, which is inconvenient for people to put on with their hands reversed; and when putting on the mask again, it is necessary to readjust the tightness of the wearing rope according to the different positions of the wearing rope on the human head. When the breathing mask needs to be temporarily removed for a short rest, or when the breathing mask needs to be frequently put on and taken off during wearing, the convenience of this wearing method is still not enough.

[0005] Therefore, a mask body is designed that can be quickly and temporarily removed and quickly and easily reset without removing the adjustment buckle or adjusting the tightness of the wearing rope, and without changing the wearing position of the wearing rope on the head, thereby effectively improving the convenience of wearing and taking off; and the research purpose of the present invention is to balance the force of the breathing mask when worn through structural improvements, thereby ensuring that the wearing of the breathing mask has a high sealing performance. Summary of the invention

[0006] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a high-seal breathing mask that can be quickly put on and taken off, and the high-seal breathing mask that can be quickly put on and taken off can effectively solve the technical problems existing in the above-mentioned prior art.

[0007] The technical solution of the present invention is: A high-seal breathing mask capable of being quickly put on and taken off comprises: A mask body, wherein both sides of the mask body are provided with corresponding air inlets, and a corresponding air outlet is provided in the middle of the lower side; A one-way valve sheet is movably mounted on the mask body at the outer side of the air outlet, and the one-way valve sheet can be opened outwards during exhalation and closed during inhalation; A sealing elastic body is installed at the edge of the mask body close to the face of the person, and the edge of the sealing elastic body is folded inwards; A protective shell is detachably fixedly mounted on the front side of the mask body, and is used to cover and protect the air outlet and the one-way valve. The protective shell is provided with an air vent that communicates the inside and outside thereof. The upper and lower ends of the protective shell are respectively provided with a group of mutually symmetrical through holes and a group of mutually symmetrical connecting holes; A swing limiter, rotatably mounted on the outside of the protective shell; used to cooperate with the installation of the first wearing rope and adjust the tightness of the first wearing rope; The first wearing rope can be movably inserted into the through hole on the left side, fixedly connected to the swing limiter, and can be movably inserted into the through hole on the right side, and its two ends are respectively wrapped around the head and then connected to each other; A second wearing rope, wherein the connecting holes are respectively connected with corresponding second wearing ropes, and the ends of the two second wearing ropes are connected; A limiting component, wherein at least one group of limiting components is arranged between the swing limiter and the protective shell, and is used to limit and fix the swing limiter after it is rotated clockwise into position, and the limiting component comprises two wedge blocks respectively fixed to the swing limiter and the protective shell; when the swing limiter is rotated clockwise into position, i.e., to the rear side of the vertical line, the first wearing rope between the swing limiter and the through hole is set in a tensioned state, and two corresponding wedge blocks overlap each other to limit and fix the swing limiter; after the swing limiter is rotated counterclockwise into position, the first wearing rope between the swing limiter and the through hole is in a relaxed state, and the breathing mask can be stretched outward along the first wearing rope through the cooperation of the through hole to be detached from the human face.

[0008] When the swing limiter is rotated clockwise to the rear side of the vertical line, the angle between the swing limiter and the vertical line where its hinge point is located is an acute angle not greater than 45°.

[0009] The protective shell includes a main body and an auxiliary body with an integrally formed protrusion arranged on the front side of the main body, the air vents are arranged through the lower side or the front side of the auxiliary body, and when the air vents are arranged on the front side of the auxiliary body, the outer side of the air vents is integrally formed and fixed with guide strips arranged at intervals from top to bottom, and the guide strips are arranged to be gradually inclined downward from the inside to the outside.

[0010] The swing limiter is arranged in a U-shaped or V-shaped structure, and the relative inner sides of its two end portions are integrally formed and fixedly connected with corresponding connecting columns. The two sides of the auxiliary body portion of the protective shell are recessed inwardly with corresponding embedding holes, and the connecting columns are respectively installed in the embedding holes to rotatably install the swing limiter on the protective shell.

[0011] The swing limiting member includes a connecting body and an integrally formed flange that protrudes upward and is arranged on both side edges of the connecting body. The flange cooperates with the connecting body to form a corresponding guide groove for limiting and accommodating the first wearing rope.

[0012] At least one group of connecting components for connecting the first wearing rope is arranged in the middle of the lower end of the connecting body, and the connecting component includes two long holes penetrating the upper and lower end surfaces of the connecting body, and the first wearing rope is fixed by alternately inserting the long holes up and down in sequence.

[0013] A first snap-on assembly and a second snap-on assembly for detachably installing the protective shell are arranged above and below the protective shell and the mask body, the first snap-on assembly comprising a snap-on base and a snap-on piece respectively fixed to the mask body and the upper side of the protective shell, the second snap-on assembly comprising a snap-on convex plate and a snap-on V-shaped piece respectively fixed to the mask body and the lower side of the protective shell, the snap-on base snaps the snap-on piece from top to bottom, and the snap-on V-shaped piece snaps the snap-on convex plate from bottom to top.

[0014] The protective housing is provided with a limiting plate for limiting and abutting against the swing limiting member, and the limiting plate is formed by extending downward from the end of the buckled V-shaped member in one piece.

[0015] A positioning block for positioning and installing the protective shell is arranged on the upper side of the mask body, and a positioning through hole matching the shape of the positioning block is arranged on the protective shell.

[0016] The ends of the first wearing rope are connected through corresponding adjustment buckles or through the cooperation of the adjustment buckle and the head support. The head support and the corresponding end of the first wearing rope are connected through the corresponding adjustment buckle, and the ends of the two second wearing ropes are also connected through the corresponding adjustment buckle.

[0017] Advantages of the present invention: 1) The present invention optimizes and improves the structure. A corresponding protective shell is detachably installed on the front side of the mask body to ensure the cover protection of the one-way valve sheet for breathing. A corresponding swing limiter is movably installed to adjust the tightness of the front end of the first wearing rope connected to the head. Therefore, without removing the adjustment buckle or adjusting the tightness of the first wearing rope, and without changing the wearing position of the first wearing rope on the head, the tightness of the first wearing rope can be quickly and conveniently adjusted by rotating the swing limiter clockwise or counterclockwise, thereby realizing the quick temporary removal and resetting of the mask body, and further effectively improving the convenience of wearing and taking off the breathing mask.

[0018] Through the structural improvement of the protective shell and the mutual cooperation of the additional swing limiter, the first wearing rope is installed by movably inserting the left through hole of the swing limiter, fixedly connecting the swing limiter, and movably inserting the right through hole in sequence. After the respiratory mask is worn, it is only necessary to adjust the rotation angle of the swing limiter to change the tightness of the first wearing rope, that is, when the swing limiter is rotated clockwise to the rear side of the vertical line, the first wearing rope between the swing limiter and the through hole is set in a tensioned state; after the swing limiter is rotated counterclockwise to the right side, the first wearing rope between the swing limiter and the through hole is relaxed, and the respiratory mask can be stretched outward along the first wearing rope through the cooperation of the through hole to be separated from the human face. The adjustment method is simpler, and the swing limiter is set on the front side, which is more convenient to operate.

[0019] 2) In addition to the above-mentioned swing limiter, the present invention further provides a corresponding fixing component between the swing limiter and the protective shell. The fixing component can be a wedge block respectively fixed to the swing limiter and the protective shell. The two wedge blocks are overlapped with each other to fix the swing limiter. This can not only ensure that the swing limiter is firmly fixed to prevent loosening and ensure the use effect, but also can easily and quickly apply external force to disengage the connection between the two wedge blocks to allow the swing limiter to rotate, further ensuring the practical effect of the present invention. And when the swing limiter rotates into place clockwise, because the first wearing rope is in a tensioned state and the angle between the swing limiter and the vertical line of its hinge point is an acute angle of no more than 45°, the swing limiter has a tendency to swing backward clockwise. At this time, the limiting component can form an effective stroke limit for the swing limiter to prevent it from continuing to swing backward. Under the interaction of forces, the two wedge blocks of the limiting component can be fastened, so that the breathing mask has a corresponding force facing the direction of the human face at the position of the limiting component, and cooperates with the two upper and lower pulling points when the original first wearing rope is installed to balance the force to avoid the bulge in the middle of the sealing elastomer, thereby ensuring the sealing performance of the breathing mask.

[0020] 3) The present invention rotatably installs a swing limiter on the outer side of the protective shell, and the first wearing rope is sequentially inserted through the through hole on the left side, fixedly connected to the swing limiter, and inserted through the through hole on the right side, and its two ends are connected to each other after being wrapped around the head. After the swing limiter is rotated clockwise into position, the first wearing rope is stretched and tensioned along the guide groove arrangement on the swing limiter. After the swing limiter is rotated counterclockwise into position, the first wearing rope is separated from the limit of the guide groove and is in a relaxed state, and the breathing mask can be movably inserted and connected with the first wearing rope through the through hole, and then the breathing mask can be pulled outward along the relaxed first wearing rope through the cooperation of the through hole without affecting the connection of the first wearing rope at the back of the head. Therefore, when putting on the mask again, the breathing mask is directly placed on the face, and the swing limiter is rotated clockwise to make the first wearing rope in a tensioned state, and the breathing mask is fixedly worn without adjusting the length of the first wearing rope by adjusting the buckle, thereby further ensuring the improvement of the practical effect of the present invention.

[0021] 4) The present invention provides at least one group of long holes in the middle of the lower end of the swing limiter for connecting the first wearing rope and the swing limiter. The long holes are preferably three symmetrical groups. The first wearing rope is connected and fixed by passing through them alternately up and down. The first wearing rope and the middle part of the swing limiter can also be fixed by existing fixing methods such as bonding and bolt locking to ensure that when the swing limiter rotates, the middle part of the first wearing rope is fixedly connected to the middle part of the lower end of the swing limiter. Compared with the existing fixing methods, the connection method of the first wearing rope and the swing limiter of the present invention improves the flexibility and simplicity of installation of the first wearing rope.

DETAILED DESCRIPTION

[0031] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings: refer to Figure 1-8 , a high-seal breathing mask that can be quickly put on and taken off, comprising: The mask body 1 has corresponding air inlets 101 on both sides thereof and a corresponding air outlet 102 in the middle of the lower side thereof; A one-way valve sheet is movably mounted on the mask body 1 outside the air outlet 102, and the one-way valve sheet can be opened outwards during exhalation and closed during inhalation; The sealing elastic body 2 is installed at the edge of the mask body 1 close to the face of the person, and the edge of the sealing elastic body 2 is folded inward; the sealing elastic body 2 can be made of rubber, silicone or other flexible materials, and is used to improve the sealing performance of the breathing mask when worn; A protective shell 3 is detachably fixedly mounted on the front side of the mask body 1, and is used to cover and protect the air outlet and the one-way valve. The protective shell 3 is provided with an air vent 301 communicating with the inside and outside thereof. The upper and lower ends of the protective shell 3 are respectively provided with a group of mutually symmetrical through holes 302 and a group of mutually symmetrical connecting holes 303; The swing limiter 4 is rotatably mounted on the outer side of the protective shell 3; it is used to cooperate with the installation of the first wearing rope 5 and adjust the tightness of the first wearing rope 5; The first wearing rope 5 can be movably inserted into the through hole 302 on the left side, fixedly connected to the swing limiter 4, and can be movably inserted into the through hole 302 on the right side, and its two ends are respectively wrapped around the head and then connected to each other; The second wearing ropes 6, the connecting holes 303 are respectively connected with corresponding second wearing ropes 6, and the ends of the two second wearing ropes 6 are connected; A limiting and fixing component, wherein at least one group of limiting and fixing components for limiting and fixing the swing limiter 4 after it is rotated clockwise into position is arranged between the swing limiter 4 and the protective shell 3, and the limiting and fixing component comprises two wedge blocks 7 respectively fixed to the swing limiter 4 and the protective shell 3; when the swing limiter 4 is rotated clockwise into position, i.e., to the rear side of the vertical line, the first wearing rope 5 between the swing limiter 4 and the through hole 302 is arranged in a tensioned state, and two corresponding wedge blocks 7 overlap each other to limit and fix the swing limiter 4; after the swing limiter 4 is rotated counterclockwise into position, the first wearing rope 5 between the swing limiter 4 and the through hole 302 is in a relaxed state, and the breathing mask can be stretched outward along the first wearing rope 5 through the cooperation of the through hole 302 to be detached from the human face.

[0032] Through structural optimization and improvement, the present invention is movably installed with a corresponding swing limiter 4 for adjusting the tightness of the front end portion of the first wearing rope 5 connected to the head, so that there is no need to disassemble the adjustment buckle or adjust the tightness of the first wearing rope 5, and without changing the wearing position of the first wearing rope 5 on the head, the tightness of the first wearing rope 5 can be quickly and conveniently adjusted by rotating the swing limiter 4 clockwise or counterclockwise, thereby realizing rapid temporary removal and resetting of the mask body 1, further effectively improving the convenience of taking off and wearing the breathing mask.

[0033] Through the structural improvement of the protective shell 3 and the cooperation of the additional swing limiter 4, the first wearing rope 5 is installed by sequentially inserting the left through hole 302 of the swing limiter 4, fixing the swing limiter 4, and inserting the right through hole 302. After the respiratory mask is worn, it is only necessary to adjust the rotation angle of the swing limiter 4 to change the tightness of the first wearing rope 5, that is, when the swing limiter 4 rotates clockwise to the rear side of the vertical line, the first wearing rope 5 between the swing limiter 4 and the through hole 302 is set in a tensioned state; after the swing limiter 4 rotates counterclockwise to the right side, the first wearing rope 5 between the swing limiter 4 and the through hole 302 is in a relaxed state, and the respiratory mask can be pulled outward along the first wearing rope 5 through the cooperation of the through hole 302 to be separated from the human face, the adjustment method is simpler, and the swing limiter is set on the front side, which is more convenient to operate.

[0034] When the swing limiter 4 rotates clockwise to the position, that is, to the rear side of the vertical line, the angle between the swing limiter 4 and the vertical line where its hinge point is located is an acute angle not greater than 45°.

[0035] The present invention, based on the additional arrangement of the above-mentioned swing limiter 4, further arranges a corresponding fixing component between the swing limiter 4 and the protective shell 3. The fixing component can be a wedge block 7 respectively fixed to the swing limiter 4 and the protective shell 3. The two wedge blocks 7 are overlapped with each other to fix the swing limiter 4, which can not only ensure that the swing limiter 4 is firmly fixed to prevent loosening and ensure the use effect, but also can easily and quickly apply external force to disengage the connection between the two wedge blocks 7 to allow the swing limiter 4 to rotate, further ensuring the practical effect of the present invention. And when the swing limiter 4 is rotated clockwise into place, because the first wearing rope 5 is in a tensioned state, and the angle between the swing limiter 4 and the vertical line where its hinge point is located is an acute angle of no more than 45°, the swing limiter 4 has a tendency to swing backward clockwise. At this time, the limiting component can form an effective stroke limit for the swing limiter 4 to prevent it from continuing to swing backward. Under the interaction of forces, the two wedge blocks 7 of the limiting component can be fastened, so that the breathing mask has a corresponding force facing the direction of the human face at the position of the limiting component, and cooperates with the two upper and lower pulling points when the original first wearing rope 5 is installed to balance the force to avoid the bulge in the middle of the sealing elastomer 2, thereby ensuring the sealing performance of the breathing mask.

[0036] The protective shell 3 includes a main body 304 and an auxiliary body 305 with an integrally formed protrusion arranged on the front side of the main body 304, and the air hole 301 is arranged through the lower side or the front side of the auxiliary body 305. When the air hole 301 is arranged on the front side of the auxiliary body 305, the outer side of the air hole 301 is integrally formed with guide strips arranged at intervals from top to bottom, and the guide strips are arranged to be gradually inclined downward from the inside to the outside.

[0037] The swing limiter 4 is arranged in a U-shaped or V-shaped structure, and the corresponding connecting columns 401 are integrally formed and fixedly connected on the relative inner sides of the two ends. The two sides of the auxiliary body 305 of the protective shell 3 are recessed inwardly with corresponding embedding holes 306. The connecting columns 401 are respectively installed in the embedding holes 306, and the swing limiter 4 is rotatably installed on the protective shell 3.

[0038] The swing limiting member 4 includes a connecting body 402 and an integrally formed flange 403 protruding upwardly and arranged on both sides of the connecting body 402 . The flange 403 cooperates with the connecting body 402 to form a corresponding guide groove for limiting and accommodating the first wearing rope 5 .

[0039] The present invention rotatably installs the swing limiter 4 on the outer side of the protective shell 3, and the first wearing rope 5 is sequentially inserted into the through hole 302 on the left, fixedly connected to the swing limiter 4, inserted into the through hole 302 on the right, and connected to each other at both ends after being wrapped around the head. After the swing limiter 4 is rotated clockwise into place, the first wearing rope 5 is stretched and tensioned along the guide groove arrangement on the swing limiter 4. After the swing limiter 4 is rotated counterclockwise into place, the first wearing rope 5 is separated from the limit of the guide groove and is in a loose state, and the breathing mask can be movably inserted and connected with the first wearing rope 5 through the through hole 302, and then the breathing mask can be pulled outward along the loose first wearing rope 5 through the cooperation of the through hole 302 without affecting the connection of the first wearing rope 5 at the back side of the head. Therefore, when the mask is put on again, the breathing mask is directly placed on the face, and the swing limiter 4 is rotated clockwise to make the first wearing rope 5 tensioned, and the breathing mask is fixedly worn without adjusting the length of the first wearing rope 5, further ensuring the improvement of the practical effect of the present invention.

The long holes 8 are preferably three symmetrical groups. The first wearing rope 5 is connected and fixed by alternately penetrating through it up and down. The first wearing rope 5 and the middle part of the swing limiter 4 can also be fixed by existing fixing methods such as bonding and bolt locking to ensure that when the swing limiter 4 rotates, the middle part of the first wearing rope 5 is fixedly connected to the middle part of the lower end of the swing limiter 4. Compared with the existing fixing method, the connection method of the first wearing rope 5 and the swing limiter 4 of the present invention improves the flexibility and simplicity of installation of the first wearing rope 5.

The first snap-on assembly includes a snap-on base 9 and a snap-on part 10 respectively fixed to the upper side of the mask body 1 and the protective shell 3, and the second snap-on assembly includes a snap-on protrusion 11 and a snap-on V-shaped part 12 respectively fixed to the lower side of the mask body 1 and the protective shell 3. The snap-on base 9 snaps the snap-on part 10 from top to bottom, and the snap-on V-shaped part 12 snaps the snap-on protrusion 11 from bottom to top.

[0043] The protective housing 3 is provided with a limiting plate 13 for limiting and abutting against the swing limiting member 4 . The limiting plate 13 is formed by extending downward from the end of the buckling V-shaped member 12 in one piece.

[0044] A positioning block 103 for positioning and installing the protective shell 3 is provided on the upper side of the mask body 1 , and a positioning through hole 307 whose shape matches that of the positioning block 103 is provided on the protective shell 3 .

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
