Description

Air purification and protection machine

This creation is about an air purifying and protecting machine, especially an air purifying and protecting machine that is worn on the chin and can continuously provide filtered air to the user's mouth and nose to form a positive pressure protection.

Today’s portable air purifiers have pumped models, such as the improvement of the Chinese patent announcement M433872 portable air filter supply device, and the M395483 portable air filter supply device. An air pump is driven by a motor to make the air pump pressure. The filtered air is delivered to the user’s mouth and nose; however, the air pump is operated intermittently, so it cannot be used to form an air curtain (air curtain) in front of the user’s mouth and nose that blocks bacteria or viruses.

Secondly, the conventional portable air filter, such as the portable air filter of China Patent Publication M553798, the portable air filter of M552573, the portable air purifier of M375520, the portable mask of 179985 that can filter air, the portable air filter of 159359 A portable face mask that can filter air, and the portable air purifier disclosed in 201114453. The wind source is an additional fan installed in a portable chassis. The fan includes at least a fan housing, a motor, and an axial fan or runoff. The fan is installed inside the portable air purifier. For the purifier, the fan casing and the air duct inside the purifier will not form a very air-tight combination with each other. There will be filtered clean air and unfiltered dirty air. The problem of mixed leakage and backflow means that the air from the purifier cannot be 100% completely filtered; moreover, directly install the existing fans on the market into the portable air purifier, because the fan may not be dedicated Design, its redundant structure (e.g. fan housing) or parts, etc., will easily cause the portable air purifier to be too large and weight increased.

In addition, some portable air filters nowadays provide a fan host and a mask. The fan host and the mask are connected by an air duct, so that users can carry the fan host with them, and then cover the mask with the mouth and nose through the guide. The air pipe guides the air filtered by the fan host to the mask. However, this structure with the airway tube connection causes some inconveniences for the user to go out and move, such as turning the head and raising the head may be blocked by the airway tube.

The main purpose of this creation is to provide an air purification and protection machine, which can be equipped with a cleaning host that can be hung on the user's chin to construct a filter that can reliably guide the filtered air to the front of the user's mouth and nose, and in the mouth and nose. The front fitting position forms the purpose of positive pressure clean air protection.

The second purpose of this creation is to provide an air purification and protection machine, which achieves the purpose of simplifying the assembly structure and being suitable for portable and hanging applications through the combination of a cleaning host and a guide cover.
