Description

Technical Field

[0001] This utility model relates to the field of protective face mask technology, specifically to a protective face mask with air regulation. Background Technology

[0002] A protective face shield is a piece of protective equipment used to protect the face from droplets, particles, or chemicals. It typically consists of a transparent face shield, a strap, and a sealing structure. Some models have built-in fans and filtration systems to improve comfort and protection. They are widely used in medical, industrial, and everyday protective scenarios.

[0003] To ensure the protective performance of the face shield, the poor breathability between the face shield and the user's face leads to the inability of the user's exhaled moisture to escape in time, which easily condenses into fog on the inside of the face shield. This not only obstructs vision, but the poor breathability of the face also reduces wearing comfort. Therefore, a protective face shield with air regulation is proposed to solve the above problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A protective face shield with air regulation includes a face shield body, and a regulation mechanism is provided on the top of the face shield body;

[0006] The control mechanism includes a support plate, an air supply pipe is embedded and fixed on one side of the inner wall of the support plate, the lower end of the air supply pipe extends to the middle of the bottom surface of the support plate, and an air outlet is opened at the lower end of the air supply pipe. A blade fan is installed inside the air outlet.

[0007] The other end of the air supply pipe extends to the outside of the support plate, and an air inlet is provided at the upper end of the air supply pipe.

[0008] The air inlet has a threaded head on its inner wall, and a filter chamber is fixedly and continuously connected to the top of the threaded head. A filter screen is embedded and fixed on the top surface of the filter chamber, and activated carbon fiber felt is pasted and fixed on the inner wall of the filter chamber below the filter screen.

[0009] As a further embodiment of this utility model: a first extension rod is fixedly connected to one side of the support plate, and a second extension rod is fixedly connected to the other side of the support plate. The first extension rod and the second extension rod are respectively fixedly connected to a hanging lug at the ends of the first extension rod and the second extension rod located away from the support plate.

[0010] As a further embodiment of this utility model: the inner wall of the first extension rod on one side is embedded and fixed with the air supply pipe, and the upper end of the air supply pipe extends to the top of the first extension rod.

[0011] As a further embodiment of this utility model: a battery compartment is fixedly connected to the top of the second extension rod on the other side, a compartment door is magnetically connected to one side of the outer wall of the battery compartment, and the bottom end of the battery compartment passes through the second extension rod and the support plate and is electrically connected to the blade fan.

[0012] As a further embodiment of this utility model: a gasket is glued and fixed to the inner side of the support plate, and the gasket is arc-shaped as a whole.

[0013] As a further embodiment of this utility model: the bottom center of the support plate is fixedly connected to the mask body, and the top center of the mask body is connected through the lower end of the air supply pipe.

[0014] As a further embodiment of this utility model: the air outlet of the blade fan faces the arched inner side of the mask body.

[0015] The beneficial effects of this utility model are:

[0016] (1) The present invention provides a blade fan inside the main body of the mask. When the blade fan is started, it can deliver air to the user's face area, thereby improving the airflow inside the mask. The water vapor exhaled by the user can be discharged downward in time, thereby reducing the probability of the mask fogging up and improving the comfort of wearing the mask.

[0017] (2) The blade fan is installed inside the air supply pipe, which extends to the side of the mask body and is equipped with an air inlet, thereby preventing the particles or impurities splashed in front of the user from directly entering the air inlet and ensuring the smooth flow of the air supply pipe.

[0018] (3) Battery compartment and filter compartment are set on both sides of the mask body to balance the weight of the mask body and prevent the user from tilting when wearing the mask. The threaded head at the bottom of the filter compartment is connected to the inside of the air inlet of the air supply pipe, and the filter screen at the top of the filter compartment can intercept particulate matter or other impurities, while the activated carbon fiber felt on the inner wall of the filter compartment can further adsorb pollutants.
