Description

Mask device

This invention is a mask device, especially a mask device that can be worn by the user and can extract the gas inside the mask to provide ventilation function.

Nowadays, people wear masks and use masks to block most dust, germs and other harmful substances in the air to prevent people from inhaling harmful substances in the air during breathing or talking.

Among them, traditional masks mainly include a mask body and ear straps respectively provided on both sides of the mask body. When the user wears the mask, the ear straps can be hung on the ears so that the mask can fit snugly. It is fixed on the face and covers the mouth and nose, and forms an internal space between the mask body and the face. Therefore, under ideal conditions, when the user wears the mask and inhales, the internal space inside the mask body will Negative pressure is formed so that external air will enter the internal space after being filtered by the mask body, thereby filtering the external air to prevent harmful substances in the air from being inhaled into the body by the user. When the user exhales, the user The spitted carbon dioxide will be discharged from the peripheral gap of the mask body.

However, in fact, when a user wears a mask, the carbon dioxide produced during breathing will enter the internal space of the mask body during the exhalation process, causing part of the carbon dioxide and air in the internal space to escape from the mask body. The outer gaps are discharged, but most of the carbon dioxide will still remain in the internal space, which makes the user easily feel suffocated by hypoxia due to high carbon dioxide concentration in the internal space of the mask when wearing the mask for a long time.

In order to prevent users from feeling suffocated due to lack of oxygen when wearing a mask for a long time, a mask device is currently sold on the market. The mask device mainly includes a mask body and a breathable component provided on the mask body.

The breathable component can draw out the air in the internal space of the mask body.

However, since the breathable component must be buckled into the corresponding buckling slot during assembly before the assembly can be completed, if the user performs the buckling action of the breathable component while wearing the mask body, Therefore, during the assembly process, the user must remove the mask body to accurately check the position of the fastening notch and align the fastening units of the breathable components. It is not buckled, so it is more inconvenient to operate.

In addition, when the breathable component is assembled to the mask body, the size of the fan inside the breathable component matches the air outlet, and the axis of the fan is located at the center of the air outlet of the mask body, and the fan will be adjacent to the air outlet. However, since the air extraction efficiency at the fan axis is poor during the rotation of the fan, the part where the fan actually provides the air extraction effect is mainly at the periphery of the fan blades, resulting in During the air extraction process of the breathable component, only the periphery of the air extraction port can provide substantial air extraction effect, so there is a problem of poor ventilation efficiency. In addition, the breathable component of the mask device must be based on practical applications.
