Description

Active anti-haze mask

technical field

The utility model relates to an anti-haze mask, in particular to an active anti-haze mask, in particular to an active anti-haze mask comprising a miniature air cleaner, an air duct and a mask body.

Background technique

In the current situation where smog has become the normal weather in some areas, how to effectively avoid the impact of air pollution on health during travel has attracted much attention. Most of the masks in the current technology have improved the airtightness in order to better prevent dust and bacteria, but this not only reduces the ventilation performance of the mask, but also increases the breathing resistance, causing the exhaled gas and inhaled gas to mix, which makes the wearer The amount of oxygen intake is greatly reduced with each breath, which not only reduces comfort, but also affects health. If the wearer himself suffers from certain bacterial respiratory diseases and needs treatment, if he wears a mask, he may even be infected repeatedly and affect his recovery.

In this regard, some masks with breathing valves have occurred in the prior art. For example, the utility model with the authorized announcement number CN204034073U discloses a mask with a new type of breathing valve, which includes an outer cover body and a filter inner cover detachably connected to the inner side of the outer cover body in a fitting manner, the outer cover body A breathing valve is fixed at the lower position of the mask, and the breathing valve is provided with a groove at one end located inside the mask; a hole is opened in the filter inner cover corresponding to the valve body, and a plastic sleeve is fixedly connected to the periphery of the hole by ultrasonic welding , the plastic sleeve is clamped in the groove of the breathing valve in an interference fit manner. The utility model divides the mask into an outer cover body and a filter inner cover. After use, the filter inner cover can be discarded and the outer cover body can be retained. This split structure design can reduce material waste and meet environmental protection requirements; at the same time, the plastic cover The sealing sleeve is tight on the valve body, which can ensure that the mask has an excellent dustproof effect, and enhance the firmness of the combination of the filter inner cover and the outer cover body.

However, although these masks with breathing valves have reduced exhaust resistance than ordinary masks, they have not fundamentally improved the mixing of exhaled and inhaled gases. In addition, after long-term use, the pollutants adsorbed in the mask will produce secondary pollution, which will seriously affect human health. In particular, when inhaling, due to the slight negative pressure inside the mask, harmful substances such as PM2.5 in the atmosphere will inevitably enter the human body from the periphery of the mask or the intake valve. effective protection.

Therefore, it is necessary to improve the mouth mask in the prior art to enhance the anti-haze protection effect of the mouth mask.

detailed description

The utility model is described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present utility model. These all belong to the protection domain of the present utility model.

An active anti-haze mask provided according to the utility model comprises: an air cleaner, an air duct and a mask body; the air cleaner purifies the air in the atmosphere, and guides the purified air into the mask body through the air duct. The air cleaner is a miniature air cleaner, wherein the miniature air cleaner refers to a portable air cleaner that can be worn on the human body, for example, can be worn on the arm or waist of the human body. The air duct is detachably connected to the mask body, for example, a plug-in connection can be adopted, so that the mask body can be used alone.

In order to avoid harmful substances such as PM2.5 in the atmosphere from entering the human body from the periphery of the mask or the intake valve due to the slight negative pressure in the mask when inhaling, the air after purification in the utility model makes the working pressure of the mask body For slightly positive pressure. The micro-positive pressure refers to the pressure generated by introducing clean air into the mask body due to the drive of the micro fan, which is slightly greater than atmospheric pressure, so that external polluted gases are not easy to enter the mask body. Further, the mask body is provided with a multi-directional flow exhalation valve, and the multi-directional flow exhalation valve adopts a one-way valve so that gas can only be discharged from the mask body but cannot enter and exit the mask body.

More specifically, the air cleaner includes a battery, an air inlet, a purification module, a fan, an air outlet, and an air adjustment knob; wherein, the battery provides power, and the battery can be a rechargeable battery or a dry battery; the air in the atmosphere passes through the air inlet successively. , the purification module, the fan, and the air outlet lead into the air duct; the air adjustment knob is set at the air outlet to adjust the air output of the air outlet. One end of the air conduit is connected to the air adjustment knob, and the other end is connected to the side of the multi-directional flow exhalation valve of the mask body. The purification module can choose electrostatic catalytic coupling module or high-efficiency particulate filter (HEPA).
