Detailed Description
The present invention is described in terms of specific embodiments, which are illustrated in the accompanying drawings, and other advantages and effects of the invention will be apparent to those skilled in the art from the disclosure herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways. Various modifications and alterations may be made in the details of this description without departing from the spirit of the invention, from various aspects and applications. In particular, the relative positions and proportions of the various elements in the drawings are merely exemplary in nature and are not intended to represent the actual conditions in which the present invention is practiced.
Aiming at the mask, the liquid added by the hydrophilic foaming body is used for adsorbing dust particles so as to filter the dust particles carried in the breathing airflow of the wearer, and the breathing airflow can move under the condition of almost no resistance by a ventilation channel penetrating through the hydrophilic foaming body, so that the wearer can breathe smoothly and discomfort is reduced, the problem that the breathing of the wearer is difficult due to the use of a high-density mask (namely, a mask with poor ventilation) in the prior art is solved, and the mask can breathe smoothly and can be used for a long time.
For the technical disclosure of the present invention, please refer to fig. 2 to 10 in the drawings.
The first embodiment:
referring to fig. 2 to 5, as shown in the drawings referred to in the left column, the mask 1 of the present embodiment can be added with liquid 132 and has a mask body 11, a gas passage structure 12, a hydrophilic foam 13 and a breathable cover 14. The mask body 11 is bent to form an air chamber 16 in the mask, and the air chamber 16 in the mask can be opposite to the mouth and the nose of a wearer to provide breathing. The mask body 11 can be made of an airtight material, so that dust particles 3 are prevented from directly passing through the mask body 11 and entering the air chamber 16 in the mask, and the dust particles 3 are prevented from being inhaled into the respiratory system of the wearer 2 to affect health. Moreover, the mask body 11 may be made of elastic materials such as elastic colloid, so that the mask body 11 can be elastically deformed to closely adhere to the face of the wearer 2, and there is almost no gap for the dust particles 3 to pass through between the mask body 11 and the face of the wearer 2, so as to effectively block the dust particles 3, thereby protecting the respiratory system of the wearer 2 from being prone to inhale the dust particles 3 and affecting health.
Referring to fig. 3 to 5, the additional airway structure 12 passes through and is combined with the mask body 11 to provide the flow of breathing gas F, and optionally has an upper annular structure 122 and a lower annular structure 123 that can be fastened to each other. In the present embodiment, the air duct structure 12 passes through the mask body 11, and is clamped and combined with the mask body 11 by the matching of the upper ring structure 122 and the lower ring structure 123, since the mask body 11 is made of an airtight material, the respiratory airflow F generated when the wearer 2 inhales only flows through the air flow passage 121 with the air passage structure 12 from the outside, and passes through the mask body 11 to enter the mask inner chamber 16 for being sucked by the wearer 2, and in addition, the breathing gas flow when the wearer 2 exhales can only pass through the gas flow channel 121 of the additional air passage structure 12, and the mask inner chamber 16 passes through the mask body 11 to be exhausted to the outside, therefore, the additional air passage structure 12 can provide the gas flow channel 121 for the breathing gas flow F, so that the external air can only pass through the additional airway structure 12 to exchange with the air chamber 16 in the mask, thereby providing the flow of breathing air F.
In addition, the hydrophilic foam 13 is disposed on the auxiliary air passage structure 12 for absorbing the liquid 132 to absorb the dust particles entrained by the breathing air flow F, so that the hydrophilic foam 13 absorbing the liquid 132 can filter the breathing air flow F flowing through the air flow passage 121, and the hydrophilic foam 13 can be made of hydrophilic material such as polyvinyl formal material, as shown in fig. 9-1 and fig. 9-2, the hydrophilic foam 13 has an air passage 131 formed by a structure extending through the main body and bending (or winding), that is, the air passage 131 extends from one side of the hydrophilic foam 13 to the other side of the open type bent air passage (open cell), the breathing air flow F can pass through the main body of the hydrophilic foam 13 by the suction force of the air passage 131, so that the breathing air flow F can travel in the auxiliary air passage structure 12 with almost no resistance, more specifically, the respiratory airflow F flowing through the ventilation channel 131 is guided by the curved ventilation channel 131, changes the flow direction, and collides against the inner wall of the ventilation channel 131. When the respiratory airflow F collides with the inner wall of the air permeable passage 131, the liquid 132 absorbed by the hydrophilic foam 13 adsorbs the dust particles 3 carried by the respiratory airflow F around the inner wall of the air permeable passage 131, so as to filter the respiratory airflow F while ensuring the flow of the respiratory airflow F, and further allow the wearer 2 to breathe clean air, thereby providing the wearer 2 with a clean breathing environment, so as to achieve the effect of filtering the dust particles 3 in the respiratory airflow F, and prevent the wearer from easily inhaling the dust particles during breathing to affect the health.
Furthermore, as shown in fig. 10, the pore size of the air permeable channel 131 of the hydrophilic foam 13 in the mask of the present invention is selected to be between 300 μm and 800 μm, so that the resistance to the passage of the breathing air flow can be effectively reduced, that is, the breathing air flow can easily flow through the air permeable channel 131 from the outside and enter the air chamber 16 in the mask, or the breathing air flow can easily flow through the air permeable channel 131 from the air chamber 16 in the mask and leave the air chamber 16 in the mask, so that the wearer 2 can breathe smoothly and reduce discomfort when wearing the mask of the present invention, thereby improving the willingness of the wearer 2 to wear for a long time.
As can be seen from the cross-sectional view shown in fig. 4, the ventilation cover 14 is combined with the attached air channel structure 12 to form a first receiving space S1 between the ventilation cover 14 and the attached air channel structure 12, and the first receiving space S1 is used for receiving the hydrophilic foam 13, wherein the ventilation cover 14 is used in combination with the upper annular structure 122 of the attached air channel structure 12, and the upper annular structure 122 and the ventilation cover 14 are fastened to each other to complete the combination of the ventilation cover 14 and the attached air channel structure 12, so that the ventilation cover 14 can allow the breathing air flow F to pass through the ventilation cover 14 and flow to the hydrophilic foam 13, and can also provide shielding for the hydrophilic foam 13 to prevent the hydrophilic foam 13 from being exposed outside, and allow the exposed hydrophilic foam 13 to affect the aesthetic property of the entire mask, and the ventilation cover 14 can provide positioning for the hydrophilic foam 13 to prevent the hydrophilic foam 13 from leaving the attached air channel structure 12, in addition, the permeable cover 14 can also protect the hydrophilic foam 13 from external force.
Furthermore, the lower ring-shaped structure 123 of the attached airway structure 12 has a pushing mechanism 1231, in this embodiment, the pushing mechanism 1231 pushes the hydrophilic foam 13 in a direction away from the face of the wearer 2, so that the hydrophilic foam 13 is away from the face of the wearer 2, that is, the hydrophilic foam 13 is separated from the face of the wearer 2, and a suitable distance exists between the hydrophilic foam 13 and the face of the wearer 2, so that the face of the wearer 2 is not easily contacted with the hydrophilic foam 13, and the wearer does not feel wet discomfort due to contact with the hydrophilic foam after absorbing liquid, thereby improving the comfort of the wearer using the mask of the present invention.
In summary, the mask of the present embodiment can be added with liquid, and has a mask body, an attached airway structure, and a hydrophilic foam. The mask body can elastically deform and is attached to the face of a wearer, so that the breathing air flow generated when the wearer inhales is prevented from entering an air chamber in the mask under the condition of not passing through an attached air passage structure. The hydrophilic foaming body is provided with a ventilation channel penetrating through the body, so that the breathing air flow can travel under the condition that the attached air channel structure is almost free from resistance, the wearer can breathe smoothly, the discomfort is reduced, and the problem that the breathing of the wearer is difficult due to the use of a high-density mask in the prior art is solved. The hydrophilic foaming body can absorb liquid, and dust particles in the respiratory airflow are absorbed by the absorbed liquid around the air-permeable passage, so that the dust particles in the respiratory airflow are filtered to clean the respiratory airflow, a clean respiratory environment is provided for a wearer to protect the health of the wearer, and the problem that the low-density mask in the prior art cannot effectively block the dust particles in the respiratory airflow is solved.
Second embodiment:
referring to fig. 6 to 8-3, as shown in the drawings referred to in the left column, the second embodiment and the first embodiment both have a mask body 11 and a hydrophilic foam 13, wherein the greatest difference between the second embodiment and the first embodiment lies in the omission of the attached airway structure in the second embodiment. In addition, in the second embodiment, the mask body 11 further has the isolation portion 15, the isolation portion 15 separates the face of the wearer 2 from the hydrophilic foam 13, and the isolation portion 15 is made of a waterproof material, so that moisture of the hydrophilic foam 13 after absorbing water is not easy to permeate the isolation portion 15, and the isolation portion 15 is damp, so that the wearer 2 feels uncomfortable, that is, when the face of the wearer 2 touches the isolation portion 15, the wearer 2 does not feel the damp isolation portion 15, and feels comfortable.
Furthermore, the isolation portion 15 is provided with an isolation portion air passage 151, and accordingly, the mask body 11 is provided with a mask body air passage structure 111. The isolating portion air passage 151 and the mask body air passage structure 111 can provide an air passage for a wearer to breathe, however, the mask body 11 itself is made of an airtight material, so that the breathing air flow F can only pass through the mask body air passage structure 111 and the isolating portion air passage 151 to enter and exit the mask inner air chamber 16, and therefore, the breathing air flow F is provided to circulate through the mask body air passage structure 111 and the isolating portion air passage 151, in detail, the breathing air flow F when the wearer 2 inhales is sequentially from the outside to enter the mask inner air chamber 16 through the hydrophilic foam 13 and the isolating portion air passage 151; when the wearer 2 exhales, the respiratory airflow F is exhausted from the air chamber 16 in the mask to the outside through the isolation air passage 151 and the hydrophilic foam 13 in sequence, thereby providing the ventilation of the respiratory airflow F for the wearer 2 to breathe.
As can be seen from the cross-sectional views shown in fig. 8-1 to 8-2, the mask body 11 can be combined with the breathable cover 14 to form a second receiving space S2 between the breathable cover 14 and the mask body 11, and the second receiving space S2 is used for receiving the hydrophilic foam 13 to prevent the hydrophilic foam 13 from leaving the mask body 11. The mask body 11 and the air permeable cover 14 are fastened to each other to complete the combination of the mask body 11 and the air permeable cover 14, so that the air permeable cover 14 can also shield the hydrophilic foam 13 to prevent the hydrophilic foam 13 from being exposed to the outside and the exposed hydrophilic foam 13 from affecting the overall beauty of the mask.
As shown in fig. 7, the air-permeable cover 14 is further provided with an observation window 141 for observing the state of the hydrophilic foam 13. The hydrophilic foam 13 may be added with a sensing material to reflect the use status of the hydrophilic foam 13 for the wearer 2 to observe, so that the wearer 2 can know the use status of the hydrophilic foam 13 in real time. In detail, the hydrophilic foam 13 may add a humidity sensing material 133. The humidity sensing material 133 can sense the degree of the liquid absorbed by the hydrophilic foam 13, and optionally, the sensing result of the humidity sensing material 133 can be displayed by a color or a pattern, wherein the humidity sensing material 133 can be optionally added with a material such as cobalt chloride to observe the humidity change, so as to indicate the liquid absorption state of the hydrophilic foam 13 in the mask 1 of the wearer 2.
To alert the wearer 2 to the addition of liquid when the hydrophilic foam 13 is too dry. In addition, the wearer 2 can observe the display result of the humidity sensing material 133 through the observation window 141 to avoid the hydrophilic foam 13 from being too dry to affect the filtering effect, so that the wearer 2 can easily notice the using condition of the mask 1 to improve the alertness, and the hydrophilic foam 13 is supplemented with liquid in real time, so that the hydrophilic foam 13 has enough liquid to adsorb the dust particles 3.
Further, the dust particle sensing material 134 is added to the hydrophilic foam 13. The dust particle sensing material 134 senses the degree of adsorption of the dust particles 3 by the hydrophilic foam 13, and optionally, the sensing result of the dust particle sensing material 134 can be presented by a color or a pattern to remind the wearer 2 to replace or clean the hydrophilic foam 13 when the hydrophilic foam 13 is excessively polluted by the dust particles 3. The wearer 2 can observe the display result of the dust particle sensing material 134 through the observation window 141 to avoid the influence of the dust particles 3 attached too much to the liquid of the hydrophilic foam 13, thereby making it easy for the wearer 2 to notice the use status of the mask 1, and to clean or replace the hydrophilic foam 13 with a new material in real time, thereby preventing the hydrophilic foam 13 excessively contaminated by the dust particles 3 from existing in the mask 1 to meet the hygienic property.
In summary, the mask body of this embodiment is provided with the waterproof isolation portion, so as to provide a thickness to separate the face of the wearer from the wet (water-absorbing) hydrophilic foam, so that the face of the wearer does not directly contact the wet hydrophilic foam, and the wearer is not likely to feel discomfort due to the moisture from the hydrophilic foam. The air permeable cover body is also provided with an observation window to provide the wearer with easy observation of the using state of the hydrophilic foaming body, so that water can be supplemented and a new material can be replaced in real time.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be as set forth in the claims of the present invention.
