Description

Technical Field

[0001] This utility model relates to the field of respiratory equipment, and in particular to a respiratory mask. Background Technology

[0002] For moisture-sensitive products, the humidity of the production environment must be strictly controlled during the manufacturing process. This is generally done in a low dew point environment, i.e., a dry room with very low humidity. Operators must wear protective clothing, gloves, and respirators to prevent the effects of body moisture on the moisture-sensitive products and harmful gases on their health. In addition, isolation covers are installed on the equipment to reduce the impact of environmental moisture on the moisture-sensitive products. Besides sweat, exhaled breath also contains moisture, which can also affect moisture-sensitive products. However, currently manufactured respirators do not strictly control the moisture content of exhaled breath. Utility Model Content

[0003] In view of this, the present invention provides a breathing mask in which a water vapor filter is installed on the air outlet of the main body of the breathing mask to absorb the moisture in the human body's exhaled air. This can prevent the water vapor in the human body's exhaled air from affecting moisture-sensitive products when the staff works in a low dew point drying room.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] In the description of this utility model, it should be noted that the orientation or positional relationship indicated in this description is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the parts or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Please see Figure 1 and Figure 2 The present invention provides a breathing mask, including a breathing mask body 10, a filter cartridge 20, and a water vapor filter 30. The breathing mask body 10 is provided with an air inlet and an air outlet. The filter cartridge 20 is installed on the air inlet of the breathing mask body 10, and the water vapor filter 30 is installed on the air outlet of the breathing mask body 10. The water vapor filter 30 is provided with a water removal device 40 inside, and a collection device 50 is provided below the water vapor filter 30.

[0022] The filter cartridge 20 is used to filter toxic gases and prevent harmful gases from harming the human body; the water vapor filter 30 is used to absorb water vapor in the human body's exhaled air, reducing or preventing water vapor from being released into the environment. Since a large amount of water vapor absorbed by the water removal device 40 will condense on it, forming condensate, a collection device 50 is provided below the water vapor filter 30. The condensate will fall under gravity and enter the collection device 50, preventing excessive condensation from affecting the water removal efficiency of the water vapor filter 30. It should be noted that the breathing mask body 10 is not limited and includes self-priming filter respirators, supplied-air respirators, and gas-storage respirators, etc. Compared to existing technologies, the breathing mask provided by this utility model has a water vapor filter 30 installed on the air outlet of the breathing mask body 10. The water vapor filter 30 can absorb water vapor in the human body's exhaled air. When the operator works in a low dew point drying room, it can prevent the water vapor in the human body's exhaled air from affecting moisture-sensitive products.

[0023] Specifically, the air inlet is located on the main body 10 of the respirator, corresponding to the mouth and nose of the human body. External air is inhaled through the air inlet, and the filter cartridge 20 is installed on the air inlet. During inhalation, the air passes through the filter cartridge 20, filtering out toxic gases. The air outlet is located on both sides of the main body 10 of the respirator, and a water vapor filter 30 is installed on the air outlet. Exhaled air enters the water vapor filters 30 on both sides, and the water vapor in the air is absorbed by the dehydration device 40 before being discharged. It should be noted that the water vapor filter 30 can be fixed to the air outlet or detachably installed on the air outlet; detachable installation is preferred because the internal dehydration device 40 may age or fail after prolonged use, facilitating later disassembly of the water vapor filter 30 and replacement of the dehydration device 40.

[0024] Furthermore, the main body 10 of the breathing mask is also equipped with a one-way inlet valve and a one-way outlet valve. The one-way inlet valve is located between the inlet and the filter cartridge 20, with one end connected to the inlet and the other end connected to the filter cartridge 20. The one-way outlet valve is located between the outlet and the water vapor filter 30, with one end connected to the outlet and the other end connected to the water vapor filter 30. The one-way inlet valve ensures that when a person inhales, the gas enters the body through the filter cartridge 20, preventing the gas from entering the water vapor filter 30. The one-way outlet valve ensures that when a person exhales, the exhaled gas enters the water vapor filter 30, and then passes through the water removal device 40 in the water vapor filter 30 to absorb the water vapor in the gas before being discharged, preventing the exhaled gas from escaping from the filter cartridge 20.

[0025] Please refer to the following: Figure 2 The water vapor filter 30 includes a housing, which is connected to and detachably connected to a one-way exhaust valve. A water removal device 40 is installed inside the housing, and a collection device 50 is installed below the housing. An air inlet is located on the side of the housing facing the one-way exhaust valve, and an exhaust port is located on the side of the housing facing away from the one-way exhaust valve. The housing is connected to the one-way exhaust valve through the air inlet. The housing supports the water removal device 40 and protects it from damage. Exhaled air enters the housing through the one-way exhaust valve and the air inlet, where it is absorbed by the water removal device 40 and then discharged through the exhaust port. Water vapor condensation formed on the water removal device 40 falls into the collection device 50 below the housing under the influence of gravity. The detachable connection between the housing and the one-way exhaust valve facilitates future replacement of the water removal device 40 inside the housing.

[0026] Furthermore, the housing includes a first housing 31 and a second housing 32. An air inlet is located on the first housing 31, which is connected to a one-way exhaust valve. The second housing 32 is detachably connected to the first housing 31, and an exhaust port is located on the second housing 32. The first housing 31 and / or the second housing 32 are made of transparent material. A water removal device 40 is installed in both the first housing 31 and the second housing 32. That is, after exhaled air enters the first housing 31 through the one-way exhaust valve, it is absorbed by the water removal device 40 within the first and second housings, and then discharged through the exhaust port on the second housing 32. The water vapor condensation formed on the water removal device 40 after absorption by the water vapor will fall into the collection device 50 below the first housing 31 under the influence of gravity. Because the second housing 32 is detachably connected to the first housing 31, it is easy to replace the water removal device 40 within the first and second housings 31.

[0027] Furthermore, the water removal device 40 includes multiple water removal layers 41 and at least one water removal material, which is attached to the water removal layers 41. The multiple water removal layers 41 are neatly arranged inside the housing 31 from the first housing 31 to the second housing 32. Since the water removal material is usually granular, the water removal layers 41 can be filter cotton or other fibrous materials, making it easy for the water removal material to adhere to the water removal layers 41. Water vapor in the breath exhaled by the human body is absorbed by the water removal material on the water removal layers 41. During the absorption process, a large amount of water vapor will form water vapor condensate on the water removal layers 41. Under the influence of gravity, the water vapor condensate will fall into the collection device 50 below the first housing 31.

[0028] Furthermore, the dewatering materials include, but are not limited to, one or more of the following: calcium sulfate, calcium chloride, activated alumina, silica gel, calcium oxide, copper sulfate, magnesium sulfate, sodium sulfate, potassium carbonate, molecular sieves, montmorillonite, activated mineral desiccants (Al2O3·4SiO2·nH2O), and fiber desiccants. Some of these dewatering materials can be reused through drying processes, saving costs. It should be noted that the first shell 31 and / or the second shell 32 are made of transparent material, allowing for easy observation of the dewatering layer 41 inside. Some of these dewatering materials will change color after reacting with water; therefore, observing the color change of the dewatering layer can indicate its water absorption capacity. If the color change is significant, it indicates excessive water absorption, and the dewatering layer inside the shell needs to be replaced promptly to avoid affecting the water absorption effect.

[0029] Furthermore, the bottom of the casing is provided with an outlet, which communicates with the collecting device 50, facilitating the falling of water vapor condensate into the collecting device 50 from the outlet. The collecting device 50 includes a connecting pipe 51 and a collecting box 52. The top of the connecting pipe 51 communicates with the outlet, and the collecting box 52 communicates with the bottom of the connecting pipe 51, and the collecting box 52 is detachably connected to the bottom of the connecting pipe 51. Water vapor condensate falls from the outlet into the connecting pipe 51 and finally into the collecting box 52. Since the collecting box 52 and the connecting pipe 51 are detachably connected, when there is too much water vapor condensate in the collecting box 52, the collecting box 52 can be disassembled to remove the water vapor condensate before reinstallation and use.

[0030] The breathing mask provided by this utility model has the following specific process for water removal: Exhaled air enters the first housing 31 of the water vapor filter 30 through the air outlet on the main body 10 of the breathing mask via a one-way exhaust valve. Inside the housing, it passes through the first water removal layer 41. The water-removing material on the first water removal layer 41 absorbs water vapor in the air. When there is excessive water vapor, condensate falls from the outlet at the bottom of the housing into the collection device 50. The air filtered by the first water removal layer 41 then passes through the second, third, and so on, water removal layers 41, and finally through the outermost water removal layer 41 and is discharged to the external environment through the exhaust port on the housing. The water-removing material in each of the aforementioned water removal layers 41 is one or more of the aforementioned water-removing materials. When replacement is needed, the water vapor filter 30 can be disassembled, the first housing 31 and the second housing 32 can be opened, and the failed water removal layer 41 or water-removing material can be replaced. Similarly, the collection box 52 can also be replaced.

[0031] As described above, the breathing mask provided by this utility model has a water vapor filter 30 installed at the air outlet of the breathing mask body 10, which can effectively control the adverse effects of water vapor in human exhaled air on moisture-sensitive products during the production process, thus solving this uncontrollable factor. Compared with the method of adding an isolation device to the outside of the equipment to prevent water vapor from affecting the product, the breathing mask provided by this utility model can eliminate the adverse effects of water vapor in human exhaled air released into the environment on moisture-sensitive products from the source of water vapor generation. This utility model is more convenient in actual operation and has obvious cost advantages.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
