Description

Technical Field

[0001] The present invention belongs to accessories for protective equipment, and relates to a sealing device for a multi-finger pressure grid type adaptive personalized mask, which is used for a sealing device for wearing a mask such as a mask, and is particularly effective in sealing irregular facial structures such as the bridge of the nose and the wings of the nose. Background Art

[0002] Disposable masks are made of more than three layers of 28g non-woven fabric; the nose bridge uses an environmentally friendly full plastic strip. According to the protection level and material, they can be divided into ordinary disposable masks, medical disposable masks and medical surgical masks. The size is about 17.5cmx9.5cm, and the wearing straps are elastic and strap-on. They have the functions of anti-virus, anti-odor, bacterial filtration, and dust prevention. They are easy to wear, comfortable, and low in cost. They are widely used in daily life and medical use. However, during use, the following defects were found: (1) The plastic strips on the nose bridge cannot press tightly against the skin; (2) The nose wings are not covered enough; (3) Glasses are prone to fogging, especially in winter; (4) The tension point is single: the facial structure is complex, and the tension point of the strap cannot be fully transmitted to the sealing interface of the mask; (5) The tension of the elastic type cannot be adjusted: the size of each person's head circumference determines the tension of the elastic band; (6) The strap-on type cannot provide continuous tension: the previously tied strap will loosen or become too tight and uncomfortable with the movement of the head and neck. Therefore, it is necessary to make the mask such as a mask sealed. Summary of the Invention

[0003] The present invention aims to address the problem of insufficient sealing in current disposable masks, particularly those with irregular facial structures such as the bridge and wings of the nose, by providing a multi-finger pressure-grid type adaptive, personalized mask sealing device.

The device comprises a pressure finger assembly 1, a center warp 2, an oblique warp A3, a weft warp 4, an oblique warp B5, a lace elastic assembly 6, a right lace 7, a left lace 8, a circular frame 9, and a bridge 10. The device structure is approximately a hemispherical three-dimensional frame. The circular frame 9 is a three-quarter arc skeleton, and the remaining quarter arc is a group of finger pressing components 1. The finger pressing component 1 group is formed by 34 finger pressing components 1 adhered to each other on the side, and the quarter arc forms a 60-degree angle with the circular frame 9. The circular frame 9 and the finger pressing component 1 group are connected through the finger pressing frame 10 to form a circular closed loop. The midpoint of the circular frame 9 arc emits an arc of the same diameter, the middle warp 2 intersecting the midpoint of the 34 finger pressing component groups. The circular frame 9 is divided into 6 equal parts, and semicircular arcs of the same diameter are emitted at the equal division points, forming oblique warp A3, oblique warp B5 and weft warp 4 respectively. The right lace 7 is connected to the right side of the circular frame 9 and is connected in series with a lace elastic component 6.

[0028] The present invention is further described with reference to the accompanying drawings and embodiments.

[0029] Example 1 Sealing device for a multi-finger pressure grid type adaptive personalized mask

[0030] Reference Figure 1-5 , Figure 19 The device of the present invention is composed of a finger pressing assembly 1, a center warp 2, an oblique warp A3, a weft warp 4, an oblique warp B5, a lacing elastic assembly 6, a right lacing 7, a left lacing 8, a circular frame 9 and a bridge column 10. The entire device is approximately a three-dimensional frame in the shape of a semi-sphere. Figure 19 The three-quarter arc (i.e., the arc corresponding to the 270-degree angle) of the circular frame 9 is the arc skeleton, and the remaining quarter arc (i.e., the arc corresponding to the 90-degree angle) is a group of finger pressing components 1. The finger pressing component 1 group is formed by 34 finger pressing components 1 adhered to each other on their sides, and the quarter arc forms a 60-degree angle with the circular frame 9. The circular frame 9 and the finger pressing component 1 group are connected by the finger pressing frame 10 to form a circular closed loop. The midpoint of the circular arc of the circular frame 9 emits an arc of the same diameter, the middle warp 2, which intersects at the midpoint of the 34 finger pressing component groups. The circular arc of the circular frame 9 is divided into 6 equal parts, and semicircular arcs of the same diameter are emitted at the equal division points, forming oblique longitude A3, oblique longitude B5 and weft 4 respectively. The right lace 7 is connected to the right side of the circular frame 9, and is also connected in series with a lace elastic component 6. The left lace 8 is connected to the left side of the circular frame 9, and is also connected in series with a lace elastic component 6. The left (right) lace is made of elastic material.

[0031] Reference Figure 6-8 The pressure finger assembly 1 is a component issued from the pressure finger frame 10 and is the dominant factor in the fixed-point pressure application. The component is composed of a pressure ball 37, a pressure column 38, a compression chamber 39, a stop 40, a spring 41, a stop window 42, a base 43 and a base cover 44. The center of the base 43 is hollowed out into a cylindrical cavity as the compression chamber 39, and long stop windows 42 are opened on both sides of the base 43 and communicate with the compression chamber 39. The rear cover of the base 43 is the base cover 44. The cylindrical pressure column 38 moves in the compression chamber 39, and the pressure finger 38 located in the compression chamber 39 sends out stops 40 on both sides and moves in the stop window 42. The pressure finger 38 located outside the compression chamber 39 is connected to the pressure ball 37 at one end, and the other end of the pressure finger 38 is connected to the spring 41, and the other end of the spring 41 is against the base cover 44. Under the elastic force of the spring 41, the pressure column 38 always maintains downward elastic potential energy. The stopper 40 moves in the stopper window 42 , ensuring that the displacement range of the pressure column 38 in the compression chamber 39 is consistent with the length of the stopper window 42 .

[0032] refer to Figure 9-12 The lace tensioning assembly 6 is a component connected in series on the right (left) lace, which plays the role of adjusting the wearing pressure. This component mainly adopts the principle of ratchet locking, and is composed of a D-ring 11, a ring seat 12, a bottom plate 13, an upper side plate 14, a tie hole 15, a hole plate 16, a lower side plate 17 and a sliding lock assembly 18. This component is a rectangular parallelepiped structure. The ring seat 12, the bottom plate 13, the upper side plate 14, the hole plate 16 and the lower side plate 17 together constitute the five faces of the rectangular parallelepiped. The remaining face is hollowed out, and the sliding lock assembly 18 is formed inside. The hole plate 16 is located at one end of the lace tensioning assembly 6, and a tie hole 15 is opened on its surface. The ring seat 12 is located at the other end of the lace tensioning assembly 6, and a semicircular D-ring 11 is located in the left and right middle position of the outer surface of the ring seat 12. The sliding lock assembly 18 slides in the hollow rectangular structure of the lace tensioning assembly 6.

[0033] Reference Figure 13 and Figure 14The slide lock assembly 18 slides within the hollow structure of the main body. The slide lock assembly 18 comprises a handle 22, a stop block 23, a fork shaft 24, a stem 25, a stem shaft 26, a stem shaft seat 27, a card shaft 28, a card shaft seat 29, a slide 30, a card spring 31, a tie ring 32, a card 33, a connecting rod shaft seat 34, a connecting rod shaft 35, and a connecting rod 36. The four sides of the sheet-like slide 30 are free. The upper surface of the slide 30 has a film shaft seat 29, a handle shaft seat 27 and a stop block 23; one end of the card 33 is connected to the slide 30 through the film shaft seat 29 with the card shaft 28 as the axis, and the upper surface of the other end of the card 33 has a connecting rod shaft seat 34, and the lower surface of the card 33 has a card spring 31, and the other end of the card spring 31 is against the slide 30; one end of the handle 25 is connected to the slide 30 through the handle shaft seat 27 with the handle shaft 26 as the axis, and the other end is connected to the handle 22. A fork shaft 24 extends horizontally from the center of each end of the rod 25. A connecting rod 36, with the connecting rod shaft 35 as its axis, is rotatably connected to the card 33 via the connecting rod shaft seat 34. The other end of the connecting rod 36 forks and is rotatably connected to the handle 25 with the fork shaft 24 as its axis. A stop block 23 extends from the upper surface of the slide 30 and is adjacent to the handle shaft seat 27. A collar 32 extends from the upper end of the slide 30 near the end of the card spring 31. The sides of the slide 30 slide within the grooves 21 of the upper and lower plates 14 and 17. When the handle 22 is pushed, the handle 25 pushes the card 33 via the connecting rod 36, causing the card 33 to rotate about the card shaft 28. The card spring 31 maintains the elastic potential energy of the card 33 (consistently keeping it in an upward position). The stop block 23 limits the rotation angle of the handle 25, so that the handle 25 can only rotate counterclockwise from a vertical position.

[0034] Reference Figure 15 , wherein the lower side plate 17 constitutes the side of the main structure, which is composed of ratchet teeth 19, plate body 20 and slide groove 21. The main structure is a rectangular plate body 20, and the upper protruding surface of the side of the plate body 20 emits ratchet teeth 19, which are consistent with the length of the plate body 20; the ratchet teeth 19 are unidirectional, that is, each tooth surface has an angle (see Figure 17 ), the angle between the small angle tooth surface in the positive direction (starting from the hole plate 16) and the horizontal line is 30 degrees, and the angle between the right angle tooth surface in the reverse direction (starting from the ring seat 12 side) and the horizontal line is 90 degrees; the two side ends of the card 33 in the sliding lock assembly 18 are in contact with the tooth surface of the ratchet 19 of the upper side plate 14 and the lower side plate 17 (see Figure 16 ); The lower portion of the inner surface of the side of the plate body 20 is concave to form a slide groove 21, which is consistent with the length of the plate body 20. The side end of the sliding seat 30 in the slide groove 21 (see Figure 16 The upper side plate 14 constitutes the other side of the main structure, and its structure is the same as that of the lower side plate 17. Figure 15 .

[0035] Example 2 Sealing device of multi-finger pressure grid type adaptive personalized mask

[0036] First wear a disposable mask normally, and then put the device on the outside of the mask.

[0037] Wearing process: Use one hand to hold the device over the disposable mask. Place the curved ring formed by the finger pressing assembly 1 over the bridge of the nose, ensuring that the frame of the device and each pressure ball 37 do not extend beyond the edge of the disposable mask. Use the other hand to attach the right and left straps 7 and 8 to the rear edge of the outer ear, then operate the strap tightening assembly 6.

[0038] Reference Figure 9-18 , operate the lace tensioning assembly 6. For one-handed operation, the thumb puts pressure on the handle 22, and the index finger or other fingers put pressure on the outside of the D-ring 11, and the two fingers make a closing motion. When the handle 22 is pushed, the stop block 23 will limit the rotation angle of the handle 25 toward the D-ring 11, that is, the handle 22 will not tilt toward the D-ring 11, so as to provide a point of force for the thumb. The card spring 31 will keep the card 33 with elastic potential energy, that is, the end edge of the card 33 will always remain in contact with the tooth surface of the ratchet 19. At this time, the tooth body angle in the positive direction is small, and the rotation direction of the card 33 is consistent with the sliding direction. The end edge of the card 33 will slide over the ratchet 19, and no locking will occur. The slide 30 will move along the slide groove 21 toward the D-ring 11, and the lace on the lace ring 32 will move closer to the D-ring 11. After releasing the grip, the elasticity of the lace will pull the slide 30 in the opposite direction, and the edge of the card 33 will abut against the ratchet 19. At this time, the angle of the teeth in the opposite direction is larger, and the rotation direction of the card 33 is opposite to the sliding direction. The edge of the card 33 will be stuck on the ratchet 19, causing a locking phenomenon. In other words, the length of the lace will remain in the shortened state.

[0039] Reference Figure 6-8 , the pressure finger assembly 1 begins to work. As the strap shortens, the pressure ball 37 contacts the outer edge of the mask, and the pressure column 38 retreats under pressure. The spring 41 releases its elastic force and applies pressure to the mask through the pressure ball 37. Each pressure ball 37 presses down according to the different heights of the skin on the nose wings and nose bridge, forming a dot-shaped pressure band that tightly adheres the edge of the mask to the outer surface of the skin. As the strap tightens, the arc-shaped circular frame 9 further applies pressure to the outer layer of the mask until it is firmly against the face.

[0040] Extraction process: refer to Figure 9-18, operate the lace tensioning assembly 6. For one-handed operation, place your thumb against the handle 22 and your index finger inside the D-ring 11. Extend your two fingers. As the handle 22 is pushed, the stem 25 pushes the card 33 via the connecting rod 36. As long as the force applied to the card 33 is greater than the friction force (i.e., the friction force between the end edge of the card 33 and the opposite tooth surface of the ratchet 19), the card 33 will rotate. Once the end edge of the card 33 exceeds the height of the ratchet 19, the locking force will disappear, and the slide 30 will move along the slide 21 toward the orifice plate 16. The lace on the lace ring 32 will move closer to the orifice plate 16, thus extending the lace length.

[0041] Reference Figure 6-8 , the finger pressing assembly 1 starts to work. As the length of the strap increases, the pressure ball 37 in contact with the outer edge of the mask begins to loosen, the elastic force of the spring 41 gradually disappears, and the tight contact state of the nose bridge and other facial skin is released.

[0042] Finally, lift and pinch the left (right) frenulum 8 (7) to remove the device, and put it into the disinfection room for disinfection before next use. The device can also be disposable.
