Description

Technical Field

[0001] This invention relates to a face mask, and more specifically, to a face mask that can be finely adjusted to adapt to the shape of the face. Background Technology

[0002] Face masks are used to cover and protect the face. Workers handling powders or conducting chemical experiments need to protect their faces from external damage. Currently, masks are commonly used to cover the face, but because everyone's face size and shape are different, using a standard mask can result in incomplete coverage and reduced effectiveness. Furthermore, due to production limitations, masks cannot be custom-made to fit every face shape, increasing production costs. To improve the mask's coverage and make it suitable for different face shapes, a face mask that can be finely adjusted to adapt to facial shapes has been designed. Summary of the Invention

[0003] The purpose of this invention is to provide a face mask that can be finely adjusted to adapt to the shape of the face, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a face mask that can be finely adjusted to adapt to facial shape is provided, including a covering component and a clamping component disposed on one side of the covering component. A receiving component is disposed on the lower side of the clamping component. The covering component covers the user's face, the clamping component clamps the user's head, and the receiving component receives the user's chin. The receiving component adjusts its position according to the height of the user's face and the shape of the jaw, so that the receiving component cooperates with the clamping component to clamp the patient's head. Through the cooperation of the clamping component and the receiving component, the covering component is fixed to the user's face.

[0005] As a further improvement to this technical solution, the shielding component includes a shielding plate, which is arc-shaped, and sealing strips are symmetrically fixed on the inner arc surface of the shielding plate near the edge. When the shielding component is in use, the sealing strips come into contact with the user's facial skin.

[0006] As a further improvement to this technical solution, the clamping member includes a forehead band, with clamping straps connected to both ends of the forehead band. Metal strips are provided inside both the forehead band and the clamping straps, and the metal strips inside the two clamping straps are offset towards each other.

[0007] As a further improvement to this technical solution, a connecting pin is fixed on the metal strip at the connection position of the forehead band and the clamping band, and one end of the connecting pin is fixed to the shielding plate.

[0008] As a further improvement to this technical solution, an extension plate is fixed on the connecting pin. The extension plate has a bent shape that moves towards the clamping band, and a threaded rod is threadedly connected to the extension plate. By rotating the threaded rod, the threaded rod pushes the clamping band, limiting the angle at which the clamping band moves away from the other clamping band.

[0009] As a further improvement to this technical solution, a breathable sponge is used to seal between the forehead band and the shield, and an inner strip is installed on the side of the forehead band and the clamping strap away from the shield. When the clamping device is worn on the user's head, the inner strip contacts the user's head, buffers the clamping force of the clamping strap on the user's head, and seals the gap between the forehead band, the clamping strap and the user through the inner strip.

[0010] As a further improvement to this technical solution, the receiving component includes a bottom strip fixed to the bottom of the baffle plate, and adjusting devices are symmetrically fixed on the upper side of the bottom strip. A jaw support is provided between the two adjusting devices, and the jaw support supports the user's lower jaw.

[0011] As a further improvement to this technical solution, the adjusting device includes a slide rod rotatably connected to the bottom strip via a ball, a slider slidably disposed on the slide rod, a spring disposed on the slide rod to move the slider toward the end of the slide rod away from the bottom strip, a side plate fixed to one side of the slider, an insert rod hinged to one end of the bottom of the side plate, a middle rod disposed between the two side plates, and one end of the insert rod slidably inserted into the inside of the middle rod.

[0012] As a further improvement to this technical solution, connecting rods are symmetrically hinged on one side of the central rod. A torsion spring is provided at the hinge position of the connecting rods. The torsion spring drives one end of the two connecting rods to move closer to each other. A soft pad is provided on the upper side of the central rod. The soft pad is U-shaped and its two sides are fixed to the side plate. The soft pad contacts the user's chin.

[0013] As a further improvement to this technical solution, the two sealing strips are connected near the bottom by a rubber strip. The middle part of the rubber strip is located on the lower side of the connecting rod. The rubber strip seals the lower side of the baffle plate, and the rubber strip drives the connecting rod to move upward. During the process of the rubber strip pulling the connecting rod, the rubber strip drives the two connecting rods to move closer to each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this face mask that can be finely adjusted to adapt to facial shape, a receiving component supports the lower jaw of the user. A rubber band and spring move the receiving component upward, making it in close contact with the lower jaw and fixing the device to the face. At the same time, the rubber band covers the lower side of the receiving component, and a sealing strip keeps the mask in contact with the user's face, separating the user's face from the external environment and effectively isolating it. Furthermore, the pressure exerted by the receiving component on the lower jaw allows the device to be adapted to users with different face shapes, expanding the device's applicability.

[0015] 2. In this face mask that can be finely adjusted to adapt to the shape of the face, by adjusting the position of the clamping strap, the clamping member can clamp heads of different sizes, and by cooperating with the receiving member to squeeze the jaw of the person, the masking member is stably fixed in the position of the user's face, so that the masking plate protects the human face.

[0020] Example 1 Face masks are used to cover and protect the face. Workers handling powders or conducting chemical experiments need to protect their faces from external damage. Currently, masks are commonly used to cover the face, but because everyone's face size and shape are different, using a standard mask can result in incomplete coverage and reduced effectiveness. Furthermore, due to production limitations, masks cannot be custom-made to fit every face shape, increasing production costs. To improve the mask's coverage and make it suitable for different face shapes, a face mask that can be finely adjusted to adapt to facial shapes has been designed.

[0021] Please see Figures 1-2 As shown, the purpose of this embodiment is to provide a face-covering mask that can be finely adjusted to adapt to the shape of the face, including a covering member 1 and a clamping member 2 disposed on one side of the covering member 1. A receiving member 3 is disposed on the lower side of the clamping member 2. The covering member 1 covers the user's face, the clamping member 2 clamps the user's head, and the receiving member 3 supports the user's chin. Through the contact between the clamping member 2 and the receiving member 3 and the user's head, the covering member 1 is fixed to the user's head so as to protect the user's face. The receiving component 3 is adjusted according to the height of the user's face and the shape of the jaw, so that the receiving component 3 works with the clamping component 2 to clamp the patient's head, and through the cooperation of the clamping component 2 and the receiving component 3, the shielding component 1 is fixed to the user's face.

[0022] The receiving part 3 changes shape according to the height, shape and volume of the user's face and jaw, so that the receiving part 3 makes close contact with the jaw of the human body. This allows the device to adapt to users with different face shapes, improves the fit between the device and the user's face, and ensures that the blocking part 1 can effectively block and protect the user's face.

[0023] The following is for reference Figures 1-7 The structure of the shielding component 1, the clamping component 2, and the receiving component 3 is further refined: The face shield 1 includes a face shield 11, which is arc-shaped and made of transparent PVC material. A sticker is attached to the face shield 11 to cover the face. The clamping component 2 includes a forehead band 21, with clamping straps 22 connected to both ends of the forehead band 21. Both the forehead band 21 and the clamping straps 22 have metal strips inside. The metal strips inside the two clamping straps 22 are offset towards each other, clamping heads of different sizes through the metal strips in the clamping straps 22, thus fixing the clamping component 2 to the user's head. At the same time, a connecting pin 23 is fixed to the metal strip at the connection between the forehead band 21 and the clamping straps 22. One end of the connecting pin 23 is fixed to the face shield 11. In this way, the clamping component 2, which is fixed to the user's head, fixes the position of the face shield 11, so that the face shield 11 is stably placed in the user's face position.

[0024] Meanwhile, in order to ensure the stability of the metal strip in the clamping band 22 in clamping the user's head, and to prevent the clamping member 2 from being insufficiently clamped when clamping a large head, an extension plate 25 is fixed on the connecting pin 23. The extension plate 25 is a bent shape that moves closer to the clamping band 22, and a threaded rod 24 is threadedly connected to the extension plate 25. By rotating the threaded rod 24, the threaded rod 24 pushes the clamping band 22, limiting the angle at which the clamping band 22 moves away from the other clamping band 22. In this way, the threaded rod 24 blocks the metal strip in the clamping band 22, preventing the metal strip in the clamping band 22 from losing its clamping effect on the head due to excessive outward displacement.

[0025] The receiving component 3 includes a bottom strip 31 fixed to the bottom of the shield 11. Adjustment devices are symmetrically fixed on the upper side of the bottom strip 31. A jaw support is provided between the two adjustment devices. The jaw support supports the user's lower jaw. The adjustment device moves the jaw support upward so that the jaw support and the user's lower jaw are in close contact. Combined with the effect of the clamping component 2 fixing it to the user's head, both the upper and lower ends of the shield 11 are fixed, thereby improving the stability of the shield 11 during use.

[0026] The adjustment device includes a slide rod 32 that is rotatably connected to the base strip 31 via a ball. The slide rod 32 can rotate at multiple angles on the base strip 31 via the ball and the base strip 31. At the same time, a slider 33 is slidably mounted on the slide rod 32. The slide rod 32 restricts the sliding position of the slider 33. A side plate 36 is fixed to one side of the slider 33. During use, the side plate 36 contacts the side of the user's face.

[0027] To enable the receiving component 3 to support chins of different sizes, a rod 35 is hinged to one end of the bottom of the side plate 36. A central rod 34 is provided between the two side plates 36. One end of the rod 35 is slidably inserted into the interior of the central rod 34. A tension spring is installed at the connection between the rod 35 and the central rod 34. At the same time, a spring is provided on the sliding rod 32 to move the slider 33 towards the end of the sliding rod 32 away from the bottom strip 31. During normal use, the spring moves the slider 33 upward, and the tension spring pulls the rod 35, causing one end of the two sliding rods 32 to move closer to each other. In this way, when the receiving component 3 supports the chin of a user with a small head and a small jaw, the side plate 36 can make stable contact with the user's side face, and the central rod 34 can also support the user's chin.

[0028] The middle rod 34 supports the user's chin, and the clamp 2 fixes the user's head, so that the shield 1 can be stably set on one side of the user's face.

[0029] To improve the stable contact between the receiving component 3 and the user's jaw, connecting rods 37 are symmetrically hinged on one side of the central rod 34. Torsion springs are installed at the hinge positions of the connecting rods 37 and 37. The torsion springs drive one end of the two connecting rods 37 to move closer to each other. When the user's jaw is placed on the central rod 34, the connecting rods 37 contact the sides of the user's neck, improving the support effect of the receiving component 3 on the user's jaw.

[0030] To improve the tightness of contact between the device and the user's face, and to isolate the face from the external environment, preventing contact between external substances and the face, a soft pad 4 is provided on the upper side of the central rod 34. The soft pad 4 is U-shaped, and its two sides are fixed to the side plate 36. The soft pad 4 contacts the user's chin. At the same time, sealing strips 12 are symmetrically fixed on the inner arc surface of the shielding plate 11 near the edge. When the shielding device 1 is in use, the sealing strips 12 contact the user's facial skin. Through the contact between the sealing strips 12 and the facial skin, the shielding is effectively sealed. The two sides of the plate 11 fit snugly against the user's face. A breathable sponge 27 seals the forehead band 21 and the shield 11. An inner strip 26 is installed on the side of the forehead band 21 and the clamping strap 22 away from the shield 11. When the clamp 2 is worn on the user's head, the inner strip 26 contacts the user's head, cushioning the clamping force of the clamping strap 22 on the user's head. The inner strip 26 also seals the gaps between the forehead band 21, the clamping strap 22 and the user, thus achieving isolation between the face and the outside.

[0031] To prevent external dust from contacting the face through the gap between the soft pad 4 and the sealing strip 12, a rubber band 13 is connected to the two sealing strips 12 near the bottom. The middle of the rubber band 13 is located on the lower side of the connecting rod 37. The rubber band 13 seals the lower side of the shield 11 to prevent dust from contacting the face. At the same time, the rubber band 13 moves the connecting rod 37 upward. As the rubber band 13 pulls the connecting rod 37, it brings the two connecting rods 37 closer together, further enabling the receiving part 3 to support the lower jaw of the human body, enhancing the lifting force of the receiving part 3 on the lower jaw, and improving the stability of the device.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
