Description

Technical Field

[0001] The utility model relates to a nasal air conditioning device, belonging to the technical field of medical and civilian compatible health products. Background Art

[0002] A significant drawback of masks and face masks is that they cover too large an area of ​​facial skin, causing a significant feeling of stuffiness and discomfort. Existing nasal air conditioning devices such as nasal masks only act on the nose and minimize this stuffiness and discomfort. However, in order to be fixed to the nose, nasal air conditioning devices usually still use ear straps or headbands, which can cause ear pain or scalp numbness after long-term use. The ear straps or headbands will also form skin marks where they pass through the face. Users generally complain about this and are not very active in using them. In addition, nasal masks are usually heavier than masks, making it difficult for hundreds of millions of users to benefit from nasal air conditioning devices. A popular nasal air conditioning device that does not require ear straps or headbands and is small and light and can meet the needs of users with different nose shapes has not yet been launched. Summary of the Invention

[0003] The utility model provides a nasal air conditioning device which does not require ear straps or head straps and is compact and light and can be directly hung on the nose for use.

[0004] The purpose of this utility model is achieved in this way:

[0005] An air conditioning device for nose includes: a mask body and a suspension arm. The mask body is shell-shaped, the inner side surface of the mask body is concave to accommodate the nose, and the outer side surface of the mask body is flat or protruding. The main body of the suspension arm is rod-shaped or sheet-shaped, one end of the suspension arm is connected to the mask body, and the other end acts on the skin of the nose. There are recesses on both sides of the mask body. One end of the suspension arm is ball-shaped and connected to the recess of the mask body as a ball head end. The left ball head end of the left suspension arm and the right ball head end of the right suspension arm are respectively embedded in the left recess of the mask body on the left side and the right recess of the mask body on the right side of the mask body to form a ball and socket joint; the other end of the suspension arm is a free end, and the left suspension arm and the right suspension arm are in contact with the skin of the nose through their respective left free ends, right free ends and / or the adjacent parts of the free ends to form friction so that the mask body is suspended on the nose without falling.

[0006] The ball-and-socket joint formed by the ball end of the suspension arm and the recess of the cover body needs to overcome the friction resistance in the ball-and-socket joint when the ball end of the suspension arm rotates slightly in the recess of the cover body. The friction resistance formed by the preferred bilateral ball-and-socket joint is greater than the gravity formed by the cover body and the suspension arm, which is convenient for individual adjustment of the distance between the free ends of the left and right suspension arms. The anatomical characteristics of the nose wing and / or nasolabial groove with significant surface transition and the characteristics that the nose skin is prone to local concave deformation after being compressed are fully utilized. The free ends of the left and right suspension arms and / or the adjacent parts of the free ends touch the nose skin in the nose wing and / or nasolabial groove area, so that the local skin is slightly The deformation creates friction to prevent the suspension arms from falling off, while the friction resistance in the ball-and-socket joint can maintain the spatial position of the left and right suspension arms. When in use, the pushing force of the skin on the suspension arms is transmitted to the ball-and-socket joint and is still smaller than the friction resistance in the ball-and-socket joint, so that the mask body and the suspension arms are hung on the nose as a whole without the need for ear straps. When the lower edge of the mask body touches the skin in the philtrum area between the upper lip and the columella, it also helps to prevent the mask body from falling off; the upper edge of the mask body can also be attached to the bridge of the nose to prevent the mask body from falling off. A structure in which the upper edge of the mask body fits fully with the skin of the nose can also prevent water vapor exhaled from the nostrils from condensing on the lenses of the glasses.

[0007] The ball-and-socket joint described in the present invention is a bionic ball-and-socket structure designed to mimic the human shoulder and hip joints. It is a multi-axis joint that allows the suspension arm to perform contraction and extension along the sagittal axis, flexion and extension along the coronal axis, and rotational movement along the vertical axis. It can also freely move along other axial directions, thereby ensuring precise contact between the free end of the suspension arm and the nose skin, balancing the center of gravity, and achieving stable suspension of the nasal air conditioning device under minimum contact force; the cavity between the inner side of the mask body and the nose skin is a humidification cavity, and what remains in the humidification cavity at the end of exhalation is saturated water vapor with a temperature close to that of the upper respiratory tract. During inhalation, at least the saturated water vapor in the humidification cavity is re-inhaled into the nasal cavity, significantly humidifying the nose. , warms the inhaled gas; because the temperature of the nasal skin is too low, it is a common inducing factor for colds, rhinitis, bronchitis and even cardiovascular accidents. When exhaling, the exhaled warm and moist airflow encounters the inner side of the mask body and then returns to flow out through the edge of the humidification cavity and / or the air outlet of the mask body. The outflowing hot and humid airflow increases the temperature of the nasal skin, improves local microcirculation, and enhances the resistance of the nose; the inner side of the mask body will also condense the exhaled saturated water vapor into tiny water droplets, which will be vaporized into water vapor and inhaled into the nasal cavity when inhaling; the utility model achieves the purpose of humidifying and warming the nasal skin and nasal mucosa of the human body in a self-service manner by intercepting the moisture and heat of the exhaled gas.

[0008] An efficiencies-enhancing structure is that the inner side of the mask body is provided with a plurality of inward protrusions for increasing the surface area in contact with the exhaled air from the nostrils, i.e., the humidification area.

[0009] In order to facilitate the assembly between the suspension arm and the cover body, the ball head end of the suspension arm and the recess of the cover body are rotatably connected by magnetic force.

[0010] At least the recess of the mask body and the ball head end of the suspension arm contain magnetic materials that can attract each other. After the ball head end of the suspension arm is placed in the recess of the mask body, it will not fall out due to magnetic attraction. The direction of the magnetic force is inward. Without the need for a strap, the free end of the suspension arm can be pressed against the skin of the nose to hang the mask body on the nose without falling off.

[0011] In order to make a nasal air conditioning device of one specification suitable for different users to the greatest extent, it also includes an intermediate arm, specifically a left and a right intermediate arm. The main bodies of the left intermediate arm and the right intermediate arm are rod-shaped and / or sheet-shaped. One end of the intermediate arm is an intermediate arm ball head end connected to the recess of the cover body, and the other end of the intermediate arm is provided with an intermediate arm recess. The left ball head end and the right ball head end of the left suspension arm and the right suspension arm are respectively embedded in the left recess and the right recess of the intermediate arm on the left and right sides to form a ball and socket joint.

[0012] The setting of the middle arm greatly increases the range of motion of the free end of the suspension arm. The curved or straight middle arm is located lower than the suspension arm, so its surface or the protruding structure on it can touch the nose wing or the skin under the nose wing, thereby helping to prevent the mask from falling off and providing multi-point auxiliary suspension. The setting of the middle arm enables a nasal air conditioning device of one specification to be suitable for different users to the greatest extent, and meet the suspension wearing needs of users with different nose wing shapes and different nose bridge heights.

[0013] In order to meet the needs of different nose shapes, the free end of the suspension arm is one or more of a spherical free end, a sheet-shaped free end, a hook-shaped free end, a ring-shaped free end, and a hammer-shaped free end; the ball head end of the suspension arm and the suspension arm body have a smooth transition or an assembly guide protrusion and an arc-shaped branch are provided at the connection between the ball head end of the suspension arm and the suspension arm body.

[0014] The assembly guide protrusion guides the ball head end of the suspension arm to enter the recess position of the cover body at a correct angle, and the ball head end of the suspension arm is solid or hollow.

[0015] Furthermore, the mask body is composed of a hard part and a flexible part. The hard part has the dimples, and the flexible part may contact the skin around the nose. The hard part and the flexible part of the mask body are connected as a whole or are detachably assembled.

[0016] The dimples on both sides of the hard part can ensure the stability of the ball and socket joint, and the flexible part contacts the skin around the nose to improve the comfort of use; when external force accidentally acts on the mask body, such as falling or collision, the flexible part can buffer the impact of external force and protect the nose.

[0017] In order to increase the types of air conditioning, in addition to temperature and humidity adjustment, the cover body is also connected to an air filter, and the air filter and the cover body are connected as a whole or are detachably assembled.

[0018] In order to increase the area of ​​the humidification chamber, it also includes an amplifying body that is conformally sleeved on the cover body when in use. The edge portion of the amplifying body at least partially exceeds the edge of the cover body. A notch or a peripherally continuous window is provided on the amplifying body, and the inner edge of the notch or the peripherally continuous window of the amplifying body is in contact with or adjacent to the edge of the cover body.

[0019] When using a small but light and beautiful cover, and want to improve the humidification and warming effects at any time, you can just put the amplifying body on the cover without removing the suspension arm and the cover. The amplifying body significantly increases the volume of the humidification chamber.

[0020] A solution to enhance warming and humidification capabilities also includes the use of a hydrogel with a water content of not less than 80%. The hydrogel is in sheet form, and the functional structure on the hydrogel includes: a plurality of villi-like protrusions on the side facing the nostrils, two extension columns protruding into or extending into the nostrils, a through hole for facilitating hanging and fixing, a suction cup facing the inner side of the mask, and one or more of a drug or non-drug volatile substance added to the hydrogel.

[0021] The hydrogel is placed on the inner side of the mask body to intercept the moisture and heat in the exhaled air from the nostrils, and release the moisture and heat when inhaling to humidify and warm the inhaled air. In order to reliably fit with the inner side of the mask body and not fall off easily, the hydrogel is provided with through holes for easy hanging and fixing. The number of through holes is preferably at least two. When in use, the through holes of the hydrogel are inserted into the inner side of the mask body, specifically on the inward protrusion; the hydrogel can also be provided with a suction cup facing the inner side of the mask body, and the suction cup refers to a local depression on the surface of the hydrogel. Circular or elliptical suction cups are preferably made when making it. In order to enhance the humidification and warming effect of the inhaled air, the hydrogel is placed towards the nose. One side of the hole is provided with multiple villi-like protrusions similar to the tentacles of anemones to increase the total surface area that can be used to humidify and warm the gas. Furthermore, the side of the hydrogel facing the nostrils is provided with two extension columns that probe or extend into the left and right nostrils. Microvilli can also be provided on the surface of the extension columns to further increase the surface area, so as to fully and timely absorb the moisture and heat in the exhaled gas from the human nostrils at a close distance, and better humidify and warm the inhaled gas when inhaling; drugs or non-drug volatile substances are added to the hydrogel, such as volatile drugs for treating rhinitis, plant essential oils for calming the nerves, plant essential oils for refreshing the mind, and various aromatic essential oils for improving breath.

[0022] In order to better increase the temperature of the inhaled gas and the skin of the nose, a heating plate is provided on the inner side of the mask body to provide a local temperature close to or higher than body temperature, which helps to heat the inhaled gas. The heating plate is an electric heating structure or a chemical structure that self-heats after contact with air, such as a heating plate containing iron powder; the heating plate with an electric heating structure can be integrated with the mask body or set independently; the heating plate also helps the water on the hydrogel to evaporate, thereby further increasing the humidity of the inhaled gas.

[0023] Furthermore, a hydrophilic coating is provided, which is arranged on the inner side of the cover body and / or the surface of the suspension arm, and can also be arranged on the inner side of the amplification body.

[0024] Hydrophilic substances can be high molecular materials such as sodium polyacrylate, polyvinyl pyrrolidone, and chitosan. When used, they can increase the water content of the hydrophilic coating by absorbing saturated water vapor with a temperature equivalent to body temperature exhaled from the human nasal cavity. When inhaling, the volatilization of water on the surface of the hydrophilic coating can increase the humidity of the inhaled gas, thereby playing a self-service humidification role for the human body, that is, the humidified water comes from the exhaled gas of the human body.

[0025] The beneficial effects of the utility model are:

[0072] The embodiments of the present invention are not limited to the following:

[0073] Example 1:

[0074] like Figure 1A-1L As shown, the nasal air conditioning device comprises: a mask body 1 and a suspension arm 3, the mask body 1 is sheet-shaped and can be made of thin-walled resin molding or metal sheet; Figure 1C The inner side surface 11 of the mask body is concave toward the nose, and the outer side surface 12 of the mask body is flat or protruding outward. The main body of the suspension arm 3 is rod-shaped or sheet-shaped. One end of the suspension arm 3 is connected to the mask body 1, and the other end acts on the nose skin when in use. There are dimples 13 on both sides of the mask body 1. The dimples 13 are located in the dimple expansion body 130. The dimple expansion body 130 is connected to the mask body 1 through a connecting column 131. The dimple expansion body 130 can also be directly set on the main body of the mask body 1; one end of the suspension arm 3 is in a ball head shape and is connected to the dimple 13 of the mask body 1 as a ball head end 31, and the left ball head end 31a of the left suspension arm 3a and the right ball head end 31b of the right suspension arm 3b The head end 31b is respectively embedded in the left recess 13a and the right recess 13b of the mask body on the left and right sides of the mask body 1 to form a ball and socket joint; the other end of the suspension arm 3 is the free end 32, and the left suspension arm 3a and the right suspension arm 3b respectively contact the skin of the nose through their respective left free ends 32a, right free ends 32b and / or the left free end adjacent parts 33a, right free end adjacent parts 33b to form friction so that the mask body 1 is suspended on the nose without falling; experiments show that when the diameter of the ball head end 31 of the suspension arm is 3mm-5mm, it has a local interference fit with the mask body recess 13, and the suspension load is higher than 25 grams.

[0075] The ball end 31 of the suspension arm 3 and the recess 13 of the cover body form a ball-and-socket joint. The rotation of the ball end 31 of the suspension arm in the recess 13 of the cover body with a local slight interference needs to overcome the friction resistance in the ball-and-socket joint. The friction resistance formed by the preferred bilateral ball-and-socket joint is greater than the gravity (suspension load) formed by the cover body 1 and the suspension arm 3, so as to facilitate individual adjustment of the distance between the free ends 32 of the left and right suspension arms; making full use of the anatomical characteristics of the nose wing and / or nasolabial groove with significant curved surface transition and the characteristics that the nose skin is prone to local concave deformation after being compressed, the free ends 32 of the left and right suspension arms and / or the adjacent parts 33 of the free ends touch the nose skin in the nose wing and / or nasolabial groove area, so that the local skin is slightly deformed to form friction to prevent the suspension arm 3 from falling off, and the friction resistance in the ball-and-socket joint can maintain the spatial position of the left and right suspension arms 3, and the skin is sensitive to the suspension arms 3 when in use. After the driving force is transmitted to the ball-and-socket joint, it is still less than the friction resistance in the ball-and-socket joint, so that the mask body 1 and the suspension arm 3 are hung integrally on the nose without the need for ear straps. When the lower side edge 14 of the mask body touches the skin in the philtrum area between the upper lip and the columella, it also helps to prevent the mask body 1 from falling off; the upper side edge 15 of the mask body can also be attached to the bridge of the nose to prevent the mask body 1 from falling off; the ball-and-socket joint described in the present invention is a bionic ball-and-socket structure design of the human shoulder joint and hip joint, which is a multi-axis joint, which can make the suspension arm 3 perform contraction and extension along the sagittal axis, flexion and extension along the coronal axis, rotational movement along the vertical axis, and free movement along other axial directions, thereby ensuring the precise contact between the free end 32 of the suspension arm and the nose skin, balancing the center of gravity, and realizing the stable suspension of the nasal air conditioning device under minimum contact force; the cavity between the inner side surface 11 of the mask body and the nose skin is a humidification cavity 0, such as Figure 1E During exhalation, the airflow path through the nostrils is as indicated by the arrows. The airflow in the humidification chamber 0 will fully contact the inner side 11 of the mask body. At the end of exhalation, the humidification chamber 0 retains saturated water vapor with a temperature close to that of the upper respiratory tract. Figure 1F The arrow indicates the inhalation airflow path. When inhaling, at least the saturated water vapor in the humidification chamber 0 is re-inhaled into the nasal cavity, which significantly humidifies and warms the inhaled gas. Because the temperature of the nasal skin is too low, it is a common inducing factor for colds, rhinitis, bronchitis and even cardiovascular accidents. When exhaling, the exhaled warm and moist airflow encounters the inner side surface 11 of the mask body and then returns to flow out through the edge of the humidification chamber 0 and / or the air outlet of the mask body (omitted in the figure). The outflowing hot and humid airflow increases the temperature of the nasal skin, improves local microcirculation, and enhances the resistance of the nose. The inner side surface 11 of the mask body will also condense the exhaled saturated water vapor into tiny water droplets, which will be vaporized into water vapor and inhaled into the nasal cavity when inhaling. The utility model achieves the purpose of humidifying and warming the nasal skin and nasal mucosa of the human body in a self-service manner by intercepting the moisture and heat of the exhaled gas.

[0076] The utility model is designed to meet the needs of users with different nose shapes for easy hanging, such as Figure 1GA free end 324 of an annular suspension arm is shown in the embodiment 1 series. Figure 1H A hammer-shaped suspension arm free end 325, Figure 1I A spherical suspension arm free end 321 is shown. Figure 1J A sheet-like suspension arm free end 322, Figure 1K A hook-shaped suspension arm free end 323 to meet the individual needs of users; Figure 1L The figure shows a suspension arm 3 with an arc-shaped branch 312 on the other side. The arc-shaped branch 312 is adjacent to the ball end 31. The arc-shaped branch 312 can touch the skin near the nostril, better wrap around the nose wing, and make the suspension of the nasal air conditioning device more stable.

[0077] A variation of this embodiment is that the suspension arm ball head end 31 and the cover body recess 13 are rotatably connected by magnetic force, which is more convenient to use.

[0078] During the specific production, at least the mask body recess 13 and the suspension arm ball head end 31 contain magnetic materials that can attract each other. After the suspension arm ball head end 31 is placed in the mask body recess 13, it will not fall off due to magnetic attraction. The direction of the magnetic force is inward, and the free end 32 of the suspension arm can be pressed against the nose skin without the need for a strap, and the mask body 1 can be suspended on the nose without falling off.

[0079] Example 2:

[0080] like Figures 2A-2F As shown, the mask body 1 of this example is composed of two parts: a hard part 1A and a flexible part 1B. The hard part 1A has a dimple 13, and the flexible part 1B may be in contact with the skin around the nose. The hard part 1A of the mask body and the flexible part 1B of the mask body are integrated or detachably assembled.

[0081] In this example, the dimple 13 and the dimple expansion body 130 constituting the dimple 13 are directly arranged on both sides of the hard part 1A of the mask body 1 to ensure the stability of the ball-and-socket joint, and the flexible part 1B contacts the skin around the nose to improve the comfort of use; when external force accidentally acts on the mask body 1, such as falling or collision, the flexible part 1B plays a role in buffering the impact of the external force and protecting the nose.

[0082] It also includes an intermediate arm 2, the main body of the left intermediate arm 2a and the right intermediate arm 2b is rod-shaped and / or sheet-shaped, one end of the intermediate arm 2 is an intermediate arm ball head end 21 connected to the cover body recess 13, the other end of the intermediate arm 2 is provided with an intermediate arm recess 22, the left ball head end 31a and the right ball head end 31b of the left suspension arm 3a and the right suspension arm 3b are respectively embedded in the left recess 22a and the right recess 22b of the intermediate arm on the left and right sides to form a ball and socket joint, and the intermediate arm recess 22 is located in the middle of the recess. Body 220; an assembly guide protrusion 211 is provided at the connection between the intermediate arm ball head end 21 and the intermediate arm 2 main body, and the assembly guide protrusion 211 guides the intermediate arm ball head end 21 to enter the cover body recess 13 position at the correct angle, and the intermediate arm ball head end 21 and / or the suspension arm ball head end 31 are solid or hollow; the suspension arm ball head end 31 and the suspension arm 32 main body have a smooth transition or an assembly guide protrusion may also be provided at the connection between the suspension arm ball head end 31 and the suspension arm 32 main body (figure omitted).

[0083] The setting of the middle arm 2 greatly increases the range of motion of the free end 32 of the suspension arm. The curved or straight middle arm 2 is located lower than the suspension arm 3, so its surface or the protruding structure on it can touch the nose wing or the skin under the nose wing, thereby helping to prevent the mask body 1 from falling off. Multiple auxiliary suspensions make a nasal air conditioning device of one specification suitable for different users to the greatest extent, and meet the suspension wearing needs of users with different nose wing shapes and different nose bridge heights.
