Description

Portable filter ventilation

The present invention relates to a ventilation device, and more particularly to a portable filter ventilation device that is detachably mounted to a mask.

Nowadays, in the environment of industrialization and transportation of vehicles, the exhaust gas emitted by factories and vehicles makes environmental air pollution increasingly serious, and the dust or aerosol particles (PM: Particulate Matter) in the air are easily inhaled in the body for a long time. Health hazards such as allergies, asthma, cardiovascular disease and respiratory diseases; therefore, many people wear masks whenever they go out to avoid excessive inhalation of impurities in the air and protect their health.

Generally speaking, the main structure of the commercially available mask is a cover body and two elastic ropes connected to both sides of the cover body, wherein the cover body is used for shielding the mouth and nose of the user, and can block the nose and mouth from directly contacting the external environment. And the cover body is filled with the filter material, so when the outside air enters the cover body, the dust in the air adheres to the cover body, and the purpose of filtering most of the impurities in the air is achieved.

However, the mask has a limited filtering effect and cannot effectively filter the adsorbed suspended particles, so there is still a problem that is harmful to the health of the body. Moreover, wearing the mask for a long time is prone to sultry and uncomfortable problems, and it is easy to reduce the user's willingness to wear the mask. .

According to the above-mentioned lack of the conventional mask, the manufacturer has developed an air filtering device, such as the Taiwan Patent No. M558885, which discloses an air purifier which can provide a mask air intake, which has a casing, a fan assembly and a mask, wherein The fan assembly is disposed in the casing, and the fan assembly is provided with a fan seat, a fan, a power source and a fan filter material, so that the fan assembly can pump air to filter impurities of the air, and the mask is connected to the casing through a connecting pipe, so that The filtered air can be transferred directly to the mask to achieve the effect of breathing fresh air.
