Non-motor vehicle helmet tool for preventing novel coronavirus

Abstract

The invention discloses a non-motor vehicle helmet tool for preventing novel coronavirus . The helmet tool includes a helmet, the top of the helmet is fixedly connected to a shell, and the inner wallof the shell is fixedly connected to a one-way valve 1 and a one-way valve 2. The shell is divided into a space A, a space B and a space C by the one-way valve 1 and the one-way valve 2, a through hole is formed in the front side of the shell, a sleeve is fixedly connected to the front side of the shell through the through hole, a motor is fixedly connected to the front side of the sleeve, a rotating shaft is fixedly connected to the rear end of an output shaft on the motor, and the surface of the rotating shaft runs through the sleeve and is fixedly connected to the inner wall of a cylindrical cam. Through cooperative use of the structures, the problems that in the actual use process, when people use non-motor vehicles like bicycles, the exercise amount is increased, the breathing frequency of people can be increased, the breathing difficulty is likely to be caused by a mask during cycling, meanwhile, a large amount of water vapor is likely to adhere to the interior of the mask, and inconvenience is brought to use are solved.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a helmet for non-motor vehicles to prevent novel coronaviruses. Background technique [0002] At present, there is no specific treatment for the disease caused by the new coronavirus; therefore, it is very important to do a good job of self-protection, such as wearing a mask when walking outdoors; [0003] At the same time, in order to avoid concentrated infection, people are also encouraged to use bicycles and other non-motorized means to go out. However, when using bicycles and other non-motorized vehicles, the increase in exercise will increase people's breathing frequency, and masks are likely to cause breathing difficulties while riding. It is also easy to cause a large amount of water vapor to adhere to the mask, which brings inconvenience to use; for this reason, we propose a helmet for preventing new coronaviruses.
