Description

Technical Field

[0001] The utility model relates to the technical field of respiratory system protection, in particular to a heating mask worn by asthmatic children. Background Art

[0002] The respiratory system is an important physiological barrier of the human body and is in closest contact with the external environment. Due to various factors, the morbidity and mortality rates of respiratory diseases at home and abroad are among the highest in the world. Understanding the characteristics of respiratory diseases and related meteorological factors is very necessary for the effective prevention of respiratory diseases. In particular, the drastic changes in related meteorological elements such as low temperatures and sudden cooling processes brought about by cold air processes will cause strong non-specific stimulation to the human body, which has a greater impact on respiratory diseases. In particular, adolescents with underdeveloped respiratory systems, especially children with asthma, react particularly violently to cold air. In order to improve the ability to keep out the cold, you can wear a mask when going out in winter. Existing masks do not have a good effect on cold air and cannot prevent the harm of cold air to the human body.

[0003] After investigation, the public announcement number: CN202020327660.1 discloses a rechargeable heated mask, which discloses "including: a first mask layer; and a second mask layer integrated on the inner side of the first mask layer; the materials of the first mask layer and the second mask layer are both medical mask fabrics; the heated mask also includes: a heating structure integrated between the first mask layer and the second mask layer; the heating structure has a heating body, and a heat-transfer and permeable gas fixed to the surface of the heating body; the surface area of ​​the heat-transfer and permeable gas is greater than the surface area of ​​the heating body." It integrates a heating structure in two layers of mask layers, which can continuously heat after power is supplied, and is used in conjunction with existing medical masks to achieve real-time heating of the worn medical mask, which not only ensures that the wearing temperature is suitable, but also avoids the condensation of exhaled water vapor to destroy the static charge in the medical mask, thereby improving the virus adsorption capacity.

[0004] However, the heating structure is directly built into the mask layers, and the heating structure and the mask layers are an integrated structure. As the number of uses increases, the mask layers and the heating structure need to be discarded together, which results in a high cost of use. In addition, there is no structure for supplying power to the heater on the mask, and power needs to be supplied by an external device during use, which is inconvenient. Therefore, we propose a heating mask for asthmatic children to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a heating mask for asthmatic children.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heated mask worn by asthmatic children, comprising a mask, a filter mesh, a heating component, and a power supply. Wearing ropes are provided on the left and right sides of the mask, an insertion pocket is sewn on one side of the front of the mask, and a power supply is plugged into the inside of the insertion pocket. A connecting line is fixedly connected to the power supply, and a quick-plug female connector is fixedly installed on the end of the connecting line. A detachable filter mesh is provided on the back of the mask, and a heating component is placed inside the mask and the filter mesh.

[0007] As a further description of the above technical solution: a "U"-shaped Velcro female patch is sewn on the back of the mask, and a Velcro male patch that cooperates with the Velcro female patch is sewn on the front of the filter mesh. The filter mesh is adhered to the mask through the Velcro male patch and the Velcro female patch to ensure that the filter mesh is firmly connected to the mask. At the same time, the filter mesh can also limit the heating component to ensure the stability of the heating component when in use, and it is easy to disassemble the filter mesh and the heating component.

[0008] As a further description of the above technical solution: the filter is made of HEPA filter material, and the area of ​​the filter is the same as the surface area of ​​the mask, ensuring that the filter can effectively filter harmful substances such as PM2.5.

[0009] As a further description of the above technical solution: a one-way breathing valve is arranged on the side of the front of the mask away from the insertion pocket. The one-way breathing valve opens when the exhalation pressure is positive, and closes when the inhalation pressure is negative. When the exhalation pressure is positive, the one-way breathing valve opens to discharge moisture and waste gas; when the inhalation pressure is negative, the one-way breathing valve closes, ensuring that the air for breathing is clean air purified by the filter.

[0010] As a further description of the above technical solution: the power supply has a built-in polymer battery that can supply power to the heating component. The power supply is externally provided with two adjustment gears. By supplying power to the heating component through the power supply, the entire mask can be heated, which not only ensures the wearing comfort, but also reduces the impact of cold air on the user.

[0011] As a further description of the above technical solution: the heating component includes two groups of non-woven fabric layers and a group of electric heating wire and a quick-plug male connector. The two groups of non-woven fabric layers are connected by hot pressing. The electric heating wire is embedded between the two groups of non-woven fabric layers. The electric heating wire is restricted by the two groups of non-woven fabric layers to ensure the stability of the electric heating wire during use.

[0012] As a further description of the above technical solution: the electric heating wire is distributed in a serpentine shape in the two groups of non-woven fabric layers, and a quick-plug male connector is fixedly installed at one end of the electric heating wire. The serpentine distribution of the non-woven fabric layers can achieve comprehensive heating of the mask and ensure the heating effect.

[0013] The utility model has the following beneficial effects:

[0014] The heated mask for asthmatic children designed by the utility model can heat the entire mask by arranging a heating component between the mask and the filter mesh, and supplying power to the electric heating wire through a power supply, which not only ensures the comfort of wearing, but also prevents the condensation of exhaled water vapor from destroying the static charge in the mask, improves the virus adsorption capacity, and reduces the impact of cold air on users, especially children with asthma.

[0015] The utility model discloses a heating mask for asthmatic children. The mask is sewn with an insert pocket for placing a power source. When in use, power can be directly supplied to the heating component through the power source, which is convenient for use. At the same time, the various structures of the mask are of split design. After long-term use, each structure can be replaced independently, thereby reducing the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1-5 The utility model provides a heated mask for asthmatic children, comprising a mask (1), a filter sheet (3), a heating component (6), and a power source (9).

[0024] In this embodiment: After investigation, the public (announcement) number: CN202020327660.1 discloses a rechargeable heated mask, which discloses "including: a first mask layer; and a second mask layer integrated on the inner side of the first mask layer; the materials of the first mask layer and the second mask layer are both medical mask fabrics; the heated mask also includes: a heating structure integrated between the first mask layer and the second mask layer; the heating structure has a heating body, and a heat transfer and permeable gas fixed to the surface of the heating body; the surface area of ​​the heat transfer and permeable gas is greater than the surface area of ​​the heating body." It integrates a heating structure in two layers of mask layers, which can continuously heat after power is supplied, and is used in conjunction with existing medical masks to achieve real-time heating of the worn medical mask, which not only ensures that the wearing temperature is suitable, but also avoids the condensation of exhaled water vapor to destroy the static charge in the medical mask, thereby improving the virus adsorption capacity.

[0025] However, the heating structure provided therein is directly built into the mask layers, and the heating structure and the mask layers are an integrated structure. As the number of uses increases, the mask layers and the heating structure need to be discarded together, and the cost of use is relatively high. In addition, there is no structure for powering the heating body on the mask, and it needs to be powered by an external device when in use, which is inconvenient to use. In view of this, in order to solve this technical problem, a heating component 6, an insert pocket 8, a power supply 9, and a Velcro male patch 4 and a Velcro female patch 5 are added to the present application document.

[0026] According to the above content, in order to facilitate the power supply to the heating component and to facilitate the replacement of the various structures of the mask, wearing ropes 2 are provided on the left and right sides of the mask 1, a pocket 8 is sewn on one side of the front of the mask 1, and a power supply 9 is plugged into the pocket 8, a connecting line 10 is fixedly connected to the power supply 9, and a quick-plug female connector 11 is fixedly installed at the end of the connecting line 10, a detachable filter screen 3 is provided on the back of the mask 1, and a heating component 6 is placed inside the mask 1 and the filter screen 3.

[0027] In this embodiment: the power supply 9 is plugged into the insertion pocket 8, and the heating component 6 can be powered when the mask is in use. It is easy to use and can heat the entire mask, which not only ensures the comfort of wearing, but also reduces the impact of cold air on the user. The power supply 9, the filter 3, the heating component 6 and the mask 1 in the mask are split-type designs. After long-term use, each structure can be replaced independently to reduce the cost of use.

[0028] As a further implementation scheme of the above technical scheme: a "U"-shaped Velcro female patch 5 is sewn on the back of the mask 1, and a Velcro male patch 4 cooperating with the Velcro female patch 5 is sewn on the front of the filter mesh 3. The filter mesh 3 is adhered to the mask 1 through the Velcro male patch 4 and the Velcro female patch 5. The filter mesh 3 is adhered to the mask 1 through the Velcro male patch 4 and the Velcro female patch 5, ensuring that the filter mesh 3 is firmly installed. At the same time, the filter mesh 3 can also limit the heating component 6 to ensure the stability of the heating component 6 during use, and at the same time it is easy to disassemble.

[0029] As a further implementation scheme of the above technical scheme: the filter sheet 3 is made of HEPA filter material, and the area of ​​the filter sheet 3 is the same as the surface area of ​​the mask 1, ensuring that the filter sheet 3 can effectively filter harmful substances such as PM2.5.

[0030] As a further implementation scheme of the above technical scheme: a one-way breathing valve 7 is arranged on the side of the front of the mask 1 away from the insertion pocket 8. The one-way breathing valve 7 opens when the exhalation pressure is positive, and closes when the inhalation pressure is negative. When the exhalation pressure is positive, the one-way breathing valve 7 opens to discharge moisture and waste gas; when the inhalation pressure is negative, the one-way breathing valve 7 is closed, ensuring that the air for breathing is clean air purified by the filter.

[0031] As a further implementation scheme of the above technical scheme: the power supply 9 has a built-in polymer battery, which can supply power to the heating component 6. Two adjustment gears are arranged on the outside of the power supply 9. The overall volume of the power supply 9 is small and the overall weight is light. Even if it is arranged on the mask 1, it will not cause a significant impact on wearing. The heating temperature of the heating component 6 can be adjusted by the adjustment gear on the power supply 9.

[0032] As a further implementation scheme of the above technical scheme: the heating component 6 includes two groups of non-woven fabric layers 61 and a group of electric heating wires 62 and a quick-plug male connector 63. The two groups of non-woven fabric layers 61 are connected by hot pressing. The electric heating wire 62 is embedded between the two groups of non-woven fabric layers 61. The electric heating wire 62 is restricted by the two groups of non-woven fabric layers 61 to ensure the stability of the electric heating wire 62 during use.

[0033] As a further implementation scheme of the above technical scheme: the electric heating wire 62 is distributed in a serpentine shape in the two groups of non-woven fabric layers 61, and a quick-plug male connector 63 is fixedly installed at one end of the electric heating wire 62. By setting the quick-plug male connector 63 and the quick-plug female connector 11, a quick connection between the heating component 6 and the power supply 9 can be achieved, so that the electric heating wire 62 is electrically connected to the power supply 9, ensuring that the heating component 6 can heat the entire mask.

[0034] Working principle:

[0035] When using the utility model, the filter screen 3 is adhered to the mask 1 by the Velcro male patch 4 and the Velcro female patch 5. When the filter screen 3 is connected, the heating component 6 is placed between the mask 1 and the filter screen 3, the power supply 9 is plugged into the insertion pocket 8, and the quick-plug male connector 63 is plugged into the quick-plug female connector 11, so that the power supply 9 can supply power to the heating component 6, and the heating temperature of the heating component 6 is adjusted by the gear position on the power supply 9. The heating component 6 heats the entire mask to ensure wearing comfort and reduce the impact of cold air on the user; the power supply 9, the heating component 6 and the filter screen 3 in the mask can be disassembled respectively. After long-term use, the mask 1 is cleaned and the filter screen 3 is replaced, and it can be used repeatedly.
