Description

An anti-fog and haze non-breathing resistance mask

technical field

The invention relates to an anti-fog and haze mask, which is suitable for people suffering from respiratory system or cardiovascular disease, in particular to an anti-fog and haze mask without breathing resistance.

Background technique

At present, in recent years, my country's smog weather has occurred frequently, and most areas have more than 5 days of smog every month in winter. The fine particles and toxic substances contained in the smog can easily cause respiratory diseases if inhaled for a long time, and serious ones can lead to Lung cancer, many areas in China have used smog as a kind of disastrous weather for early warning and forecasting. An effective measure to prevent smog is to wear an anti-smog mask. The existing anti-smog mask utilizes the negative pressure formed in the closed space of the mask when the human body inhales, forcing the outside air to enter the mask through the smog filter, and the air The smog in the air is filtered out. Because the pore size of the smog mask filter is less than 0.3 microns (ordinary 16-layer gauze masks are about 100 microns), the breathing resistance is very large, and it is difficult to breathe. People with respiratory system or cardiovascular diseases It is not easy to wear, even if a normal person wears it for a long time, there will be symptoms of hypoxia, so it can only be used as a temporary emergency, which limits the use of anti-smog masks, so an anti-smog mask without breathing resistance is needed. Existing mouth masks have installed air extraction or exhaust micro-fans, exhaust fans, etc., but the defect of this design is that the air suction produced is very little.

Contents of the invention

The purpose of the present invention is to overcome above-mentioned deficiencies in prior art, provide a kind of anti-smog mask without breathing resistance, while filtering smog, do not produce breathing resistance, especially suitable for people with respiratory system or cardiovascular disease to wear.

To achieve the above object, the present invention adopts the following technical solutions:

An anti-fog and haze non-breathing resistance mask, comprising a casing, the casing is a raised shell in the middle, and the casing is sequentially provided with an air suction chamber and an air storage chamber from the inside to the outside, and the air suction chamber The top of the top is provided with a smog filter, and the suction chamber includes a cylinder, a piston, a crank and a connecting rod, the cylinder is connected to the crank, the crank is connected to the connecting rod, and the connecting rod is connected to the piston. And the third one-way ventilation valve is installed on the piston; the gas storage chamber includes an upper end cover and a lower end cover, the upper end cover is a side close to the suction chamber, and the upper end cover and the lower end cover are respectively provided with There are a first one-way ventilation valve and a second one-way ventilation valve; a motor is arranged on the upper part of the outer surface of the casing, and the motor is connected with a power supply; a plurality of air outlets are arranged on the lower side of the outer surface of the casing.

The cover is provided with a hook for hooking on the ear.

Preferably, the hook and hanger is an elastic band.

The smog filter is detachably connected to the casing, and when the filter becomes dirty, only the filter needs to be replaced, which reduces the cost.

Preferably, the cover is made of a transparent material, therefore, the wearer's facial expression can be seen through the mask, which increases the communication and interaction between the wearer and others.

The beneficial effects of the present invention are:

1. The present invention drives the crank in the suction chamber to rotate through the motor, and the rotation of the crank is converted into the up and down reciprocating motion of the piston in the suction chamber through the connecting rod; when the piston moves upward, the one-way ventilation valve on the piston opens, and when the piston moves downward At this time, the third one-way ventilation valve on the piston is closed, the first one-way ventilation valve of the air storage chamber is opened, the air in the cylinder is compressed into the air storage chamber, and at the same time, the negative pressure is generated due to the movement of the piston, forcing the outside air to pass through the smog The filter screen enters the cylinder to filter out the smog in the air; when the human body inhales, the second one-way ventilation valve of the air storage chamber opens, and clean air enters the casing; when the human body exhales, the air storage chamber The second one-way ventilation valve is closed, and the exhaust gas produced by the human body is discharged through the vent hole on the cover. There is no breathing resistance during the whole breathing process. It is especially suitable for people with respiratory system or cardiovascular diseases, and it is not easy for normal people to wear it for a long time. Symptoms of hypoxia will occur;

2. The parts of the present invention can all be assembled on the surface of the casing, and the structure is simple and light, and easy to wear.
