Description

Technical Field

[0001] The utility model relates to the technical field of masks, in particular to a head-mounted air respirator. Background Art

[0002] Safety accidents such as fires and natural disasters will cause significant loss of life and property to society. At the same time, these safety accidents often produce thick smoke and harmful gases, which puts rescue work under severe challenges. During the rescue process, rescuers wear air breathing masks to protect themselves.

[0003] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed a "head-mounted air-purifying respirator" with the application number "201720474684.8". The patent mainly uses a high-efficiency adsorption air purification device based on the principle of high-voltage strong electric field, which does not require the replacement of consumables, has a simple structure, and is small in size. The process of outside air entering the high-efficiency adsorption air purification device from the air inlet is not hindered, and there is no pressure difference between the air inlet and the first one-way valve. The air pressure in the main unit can be balanced with the outside air pressure to avoid holding breath. However, when the user is in a fire environment, the high temperature in the environment will cause the temperature of the gas inhaled by the user to be high, which will cause discomfort to the user, increase the body heat of the user, and cause the user to sweat significantly, thereby reducing the sustainable working time in the fire scene. Utility Model Content

[0004] The purpose of the utility model is to provide a head-mounted air respirator, which can be integrated with an optical camera worn through an independently developed optical solution and a deep learning AI algorithm, has advanced infrared technology, and has the characteristics of low power consumption, small size, and high resolution. It can free the user's hands and improve combat efficiency. The temperature of the air transmitted from the gas tank to the protective mask through the gas pipe can be reduced through a cooling mechanism, thereby reducing the heat brought by the user due to breathing hotter air, improving the user's comfort, and thus extending the user's sustainable working time at the fire scene.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A head-mounted air respirator comprises a protective mask, an optical camera is fixedly connected to the outside of the protective mask, a filtering mechanism is arranged inside the protective mask, a cooling mechanism is arranged inside the protective mask, an air pipe is fixedly connected to the inside of the cooling mechanism, and an end of the air pipe away from the cooling mechanism is fixedly connected to a gas storage tank.

[0007] As a further solution of the utility model: the cooling mechanism includes a mechanism shell fixedly connected to the inside of the protective mask, the mechanism shell is fixedly connected to the outside of the air pipe, and the end of the air pipe away from the air tank is fixedly connected to a fixed pipe.

[0008] As a further solution of the utility model: the fixing tube is fixedly connected to the inside of the mechanism housing, and a threaded groove is provided inside the fixing tube.

[0009] As a further solution of the utility model: a fixing sleeve is fixedly installed on one end of the mechanism housing located outside the protective mask, and a connecting plate is fixedly connected to the inner wall of the fixing sleeve.

[0010] As a further solution of the utility model: a circular plate is fixedly connected to a side of the connecting plate away from the fixing sleeve, and a cone is fixedly connected to a side of the circular plate close to the fixing pipe.

[0011] The beneficial effects of the utility model: the integrated wearable optical camera with independently developed optical solutions and deep learning AI algorithms has advanced infrared technology, and its low power consumption, small size, and high resolution can free the user's hands and improve combat efficiency. The fixed tube is fixedly connected to the inside of the mechanism shell, and a threaded groove is opened inside the fixed tube. The air supply pipe enters the inside of the fixed tube along the tangent direction of the fixed tube, and forms a vortex with the threaded groove in the fixed tube, and enters the end of the mechanism shell where the fixed sleeve is fixed. In the process of the vortex approaching the fixed sleeve, the angular velocity of the airflow near the center is the largest, while the angular velocity of the airflow near the wall tube of the mechanism shell is relatively low. The vortices of the inner and outer circles are generated due to the difference in angular velocities. Friction, in order to maintain rotation, the inner circle vortex will continuously convert the internal energy of the gas into the required kinetic energy, which causes the internal energy to decrease continuously and the temperature of the inner circle vortex to decrease, while the outer circle vortex obtains kinetic energy through friction and keeps rotating, causing the temperature of the outer circle vortex to continue to rise. Finally, the outer circle vortex passes through the air outflow device between the circular plate and the fixed sleeve, while the inner circle vortex returns after hitting the cone and finally flows out through the end of the mechanism shell away from the fixed sleeve and enters the protective mask to cool down the user. This solves the problem that the user's breathing temperature is high in a high temperature environment, which increases the heat in the body, and then causes the user to sweat profusely, reduces the continuous working time, and may even cause serious consequences such as damage to the internal organs.

The air supply pipe 5 is fixed along the tangent position of the fixed pipe 42, so that when the air supply pipe 5 transmits the compressed air in the air storage tank 6 to the fixed pipe 42, a vortex can be better formed, thereby improving the cooling efficiency of the cooling mechanism 4.

[0021] The fixing pipe 42 is fixedly connected to the inside of the mechanism housing 41, and a threaded groove 43 is provided inside the fixing pipe 42. A dustproof net can be added inside the end of the mechanism housing 41 away from the fixing sleeve 44 to prevent the operator from inhaling too much dust, which may have a bad effect on the body.

[0022] The device comprises a protective mask 1, an optical camera 2 is fixedly connected to the outside of the protective mask 1, a filtering mechanism 3 is arranged inside the protective mask 1, and a cooling mechanism 4 is arranged inside the protective mask 1. Protective covers that do not hinder the operation of the device can be added inside and outside the cooling mechanism 4, the outer one prevents the cooling mechanism 4 from being damaged by the operator during operation, thereby causing adverse consequences, and the inner one prevents the user from directly colliding with the cooling mechanism 4, thereby causing damage to the cooling mechanism 4 or the user, thereby improving the stability and safety of the device.

[0023] The cooling mechanism 4 is fixedly connected to an air pipe 5, and one end of the air pipe 5 away from the cooling mechanism 4 is fixedly connected to an air tank 6. The outside of the air tank 6 can be provided with anti-slip patterns to reduce the probability of the air tank 6 falling off when the operator carries the air tank 6 for combat, and a fixed binding ring can be added to the outside of the air tank 6 to further improve the stability of the device.

[0024] A circular plate 46 is fixedly connected to the side of the connecting plate 45 away from the fixing sleeve 44, and a cone 47 is fixedly connected to the side of the circular plate 46 close to the fixing tube 42. A pattern may be provided on the side of the circular plate 46 away from the cone 47 to increase the area of ​​the circular plate 46 in contact with the air, thereby improving the heat dissipation capacity of the circular plate 46 and preventing the circular plate 46 and the cone 47 from being damaged and deformed due to excessive temperature.

[0025] A fixing sleeve 44 is fixedly mounted on one end of the mechanism housing 41 outside the protective mask 1, and a connecting plate 45 is fixedly connected to the inner wall of the fixing sleeve 44.

[0026] The working principle of the utility model is as follows: after putting on the protective mask 1 and the gas tank 6, the gas tank 6 is started, so that the compressed air in the gas tank 6 enters the gas delivery pipe 5, and then enters the interior of the fixed tube 42 along the tangent direction of the fixed tube 42 through the gas delivery pipe 5, cooperates with the thread groove 43 in the fixed tube 42 to form a vortex, and enters the end of the mechanism housing 41 where the fixed sleeve 44 is fixed. In the process of the vortex approaching the fixed sleeve 44, the angular velocity of the airflow near the center is the largest, while the angular velocity of the airflow near the wall tube of the mechanism housing 41 is relatively low. The vortex of the inner and outer circles generates friction due to the different angular velocities, and the vortex of the inner circle is In order to keep rotating, the internal energy of the gas will be continuously converted into the required kinetic energy, which causes the internal energy to decrease continuously, the temperature of the inner circle vortex decreases, and the outer circle vortex obtains kinetic energy through friction and keeps rotating, causing the temperature of the outer circle vortex to increase continuously. Finally, the outer circle vortex passes through the air outflow device between the circular plate 46 and the fixed sleeve 44, and the inner circle vortex returns after hitting the cone 47 and finally flows out through the end of the mechanism shell 41 away from the fixed sleeve 44 into the protective mask 1, cooling the user, and then starting the optical camera 2. At this time, preparation is complete. After the equipment is detected to be correct, the user can carry the device into the workplace.
