Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in figures 1-4, the multifunctional face mask mainly for protecting the working of the mower comprises an annular outer mask 1 and a soft inner mask 11. The soft inner cover 11 is fixed at the inner rear part of the annular outer cover by ultrasonic welding technology. An inner triangular support 3 is connected between the left side and the right side of the front surface of the annular outer cover 1, and transparent bodies are respectively fixed in the inner areas of the annular outer cover 1 at the upper part and the lower part of the inner triangular support 3, so that a transparent mask 2 is formed. The inside triangular support 3 is fixed with inside lining 13 to the wall adhesion backward, installs second grade check valve 5 in the inside triangular support, and in the exit end orientation multi-functional face guard of second grade check valve 5, the entrance point intercommunication of second grade check valve 5 had filter bag 4.

Transparent face guard 2 adopts the light material polycarbonate integrated into one piece of high strength, possesses buffering shock attenuation effect to with have 25 millimeters gaps between the user face, can not directly influence the head and face because of the atress warp. In addition, the transparent mask 2 has a smooth surface and an almost streamlined shape, and when hard objects such as broken stones and the like which are rotated by the blades impact the transparent mask 2, the impacted objects cannot be balanced, can slide and roll, and can rapidly leave the surface; and the force of the impact point is transmitted to the surrounding area, the impact force can be reduced by two thirds through the buffering and reducing of the lining 13, other forces are transmitted to the head and face of the person through the whole area of the soft lining 11, thus the stress point is changed into the stress surface, the stress concentration of the impact force on a certain point on the transparent mask 2 is prevented, and the stress of the unit area is reduced.

Lock catch type breather valve 6 assembles in the lower part of transparent face guard 2 (being the transparent body of interior triangular supports 3 lower parts) and is close to the oronasal department position of people's face, lock catch type breather valve 6 is including netted casing 7, netted casing 7 is connected through the lock catch and is fixed in the mounting hole of transparent face guard 2 lower part, first active carbon 8 has set gradually in netted casing 7, moisture absorption gauze 9 and one-level check valve 10, the gas of human body exhalation is in proper order through one-level check valve 10 in the whole multifunctional face guard, moisture absorption gauze 9, first active carbon 8 outwards discharges. The lock catch type vent valve 6 is arranged on the transparent face mask 2, can be detached and replaced with polluted active carbon 8, moisture absorption gauze 9 and the like, is recycled, and has the function of removing the turbid air breathed out and simultaneously preventing the outside air from contacting the face mask.

The external air flow enters the multifunctional mask through the detachable disinfection air filtering component 15 on the upper part of the annular mask 1, a communication port is specifically arranged on the annular mask 1, and the disinfection air filtering component 15 is inserted in the communication port. Three layers of gas filtering and exchanging materials are arranged in the disinfection gas filtering component 15, the flock spraying cloth 18 is arranged on the top layer, the filtering gasket 17 is arranged on the middle layer, the second active carbon 16 is arranged on the bottom layer, the inlet end of the disinfection gas filtering component 15 faces outwards, and the outlet end of the second-stage check valve 5 in the inner triangular support 3 is communicated with the outlet end of the disinfection gas filtering component 15 through the filter bag 4. The outside air passes through the lint 18, the filter pad 17 and the second activated carbon 16 in sequence, the disinfection air filter part 15 primarily filters harmful tail gas, working floating dust and germs of the engine, and then the fresh air reaches the inner triangular support 3, passes through the filter bag 4 to be cleaned again and then enters the multifunctional face mask through the second-stage one-way valve 5 for breathing and inhalation of a human body. The filter bag 4 and the secondary one-way valve 5 can be replaced periodically.

The sleeve belts 12 are two, one end of each sleeve belt is fixed at the symmetrical position of the upper part of the annular inner cover 1, the other end of each sleeve belt is fixed with a connecting lock catch 14, the symmetrical positions of the lower part of the annular inner cover 1 are fixed with a buckle seat, and the connecting lock catches 14 are connected with the buckle seats respectively.

The soft inner cover 11 is sealed with the periphery of the head and face, and has the function of isolating the inner space of the mask from the outer space, preventing dust, harmful gas and the like from leaking into the inner space of the mask and ensuring the normal work of the breathing system of the mask. The middle of the two sleeve belts 12 is provided with an anti-skid adhesive strip 19 for adjusting the size; the head sizes of users with different body types are adapted.

The lining 13 and the soft inner cover 11 are made of soft skin-friendly silica gel materials, are anti-aging, anti-allergic and durable, are tightly attached to the facial contour of a user, effectively ensure the sealing performance of the protective mask and meet the requirement of wearing safety and comfort for a long time. In addition, on the basis of meeting the working protection of the mower, the high-temperature-resistant sticking film is stuck on the surface of the transparent mask 2, so that the high-temperature-resistant sticking film can be applied to the protection of a respiratory system of a human body in sudden high-temperature smoke occasions such as fire emergency and the like, and the valuable time of disaster relief and escape is won; in addition, the head of the face mask can be optionally matched with a long-distance ventilation fitting, and the face mask can also be used for leisure and entertainment requirements such as floating and diving swimming and the like, so that the multifunctional purpose of the face mask is realized.

The multifunctional mask can protect the impact of particles such as broken stones on the critical parts of the head, and can prevent harmful tail gas, floating dust and germs of an engine from entering a respiratory system by passing active materials such as high-energy particles for many times in different spaces. On the basis of realizing the protection function of the mower, the outer side of the face mask can also be applied to the damage of high-temperature smoke dust and the like to human bodies in the field of fire fighting by directly adopting high-temperature-resistant materials or using high-temperature-resistant sticking films, thereby winning precious time for ordinary people to rescue in case of emergency. In addition, the head of the face mask can be optionally matched with a long-distance ventilation fitting, and the face mask can also be used for leisure and entertainment requirements such as floating and diving swimming and the like, so that the multifunctional purpose is realized.

The embodiments of the present invention are described only for the preferred embodiments of the present invention, and not for the limitation of the concept and scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall into the protection scope of the present invention, and the technical content of the present invention which is claimed is fully set forth in the claims.
