Description

Active ventilation mask

Technical Field

The utility model belongs to the technical field of masks, and relates to an active ventilation mask.

Background

The mask is a human respiratory tract protective article, which can prevent harmful particles, gas, smell and spray from entering and exiting human respiratory tract.

The existing mask cannot actively remove the waste gas in the mask, and part of carbon dioxide exhaled by a human body is inhaled again by the human body, so that the oxygen supply of blood of the human body is insufficient, and especially when the human body moves, the metabolism of the human body is inhibited, and the human body health is adversely affected.

In patent application number CN201610974565.9, an active ventilation mask ventilation method and a mask ventilator are disclosed, the technical scheme adopts a motor to inhale to accelerate air circulation, but negative pressure suction generated by a negative pressure structure of the mask ventilator can adsorb cheek skin or mask cloth, thereby blocking a circulation channel from a nose wing to a negative pressure air port, leading to ventilation air brought by the negative pressure suction, and not actually and effectively acting on nostrils, thereby leading to the fact that at the negative pressure air suction port, the negative pressure suction directly adsorbs air outside the mask to form an air circulation channel, and therefore, an active ventilation mask is provided.

Disclosure of utility model

The utility model aims to solve the problems existing in the prior art, and provides an active ventilation mask, which aims to solve the technical problems that: firstly, how to solve active ventilation, and secondly, how to prevent negative pressure from adsorbing adverse effects from skin or mask cloth belts.

The aim of the utility model can be achieved by the following technical scheme: the utility model provides an initiative mask of taking a breath, includes mask body, bridge of the nose strip and ear area, the mask body is equipped with breather, breather is including setting up the mount pad at the mask body, the lateral surface of mount pad is equipped with the motor, the mount pad has a indent cavity, the indent cavity is equipped with the flabellum of being connected with the motor shaft, the lateral wall of indent cavity is equipped with a plurality of ventilation holes, the medial surface of mount pad is equipped with and is netted bellied air intake skeleton, air intake skeleton surface cover has the filter bag rather than the adaptation, the elastic cord has in the sack of filter bag, the medial surface of mount pad still is equipped with the clamp that supplies the elastic cord buckle.

Further, the inner side surface of the mounting seat is also provided with a broken annular bulge.

The beneficial effects are that: compared with the prior art, the utility model has the advantages that the axial flow fan is changed into the centrifugal fan, so that the negative pressure suction pressure is further increased, the net-shaped bulge-shaped air inlet framework and the broken annular bulge are additionally arranged at the air inlet, the area of the air inlet is increased, and the phenomenon that the air circulation is unsmooth due to the fact that the negative pressure suction adsorbs cheek skin or mask cloth is effectively prevented, and the smooth breathing of people wearing the mask is effectively ensured.

Detailed Description

As shown in fig. 1-6, the following is a specific embodiment of the present utility model and the technical solution of the present utility model is further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments, and an active ventilation mask includes a mask body 1, a nose bridge strip and an ear strap 2, where the mask body 1 is provided with a ventilation device, the ventilation device includes a mounting seat 3 disposed on the mask body 1, a motor 4 is disposed on an outer side surface of the mounting seat 3, the mounting seat 3 is provided with an inner cavity chamber 5, the inner cavity chamber 5 is provided with a fan blade 6 connected with a shaft of the motor 4, a side wall of the inner cavity chamber 5 is provided with a plurality of ventilation holes 7, an inner side surface of the mounting seat 3 is provided with an air inlet skeleton 8 having a mesh-shaped protrusion, a surface of the air inlet skeleton 8 is covered with a filter bag adapted with the air inlet, an elastic band is disposed in a mouth of the filter bag, and a clip 9 for fastening the elastic band is disposed on an inner side surface of the mounting seat 3.

Preferably, the inner side surface of the mounting seat 3 is also provided with a broken annular protrusion 10.

In this embodiment, the end face of the motor 4 is provided with a switch 11, and the switch 11 is provided with two gears, wherein the first gear is used for normal breathing ventilation and the second gear is used for strenuous exercise to strengthen ventilation.

The air inlet framework 8 and the broken annular protrusions 10 are made of silica gel materials and have certain elasticity and tension.

The mounting seat 3 and the clamp 9 are made of hard plastics, and the filter bag is made of a gauze mask filter cotton pad.

When the mask is required to be worn, the ear belt 2 is tied on ears, nose bridge strips are pinched to be clung to nose wings and form a small gap so as to facilitate air circulation, if the mask works normally, the first gear of the switch 11 is pressed down, the motor 4 operates to drive the fan blades 6 to rotate, the fan blades 6 discharge air from the side wall vent holes 7 of the mounting seat 3, negative pressure potential energy is formed at the air inlet, the air inlet framework 8 with the net-shaped protrusions effectively prevents negative pressure suction from adsorbing cheek skin or mask cloth at the air inlet, the annular protrusions 10 can effectively assist the mask cloth at the air inlet not to be adsorbed by negative pressure air flow, thereby leading the mask cloth to be clung to skin, enabling waste gas exhaled by human nostrils to be circularly adsorbed by the negative pressure air flow, the waste gas is filtered by the filter bag wrapped on the air inlet and enters the concave cavity 5, and is discharged by the fan blades 6, and the waste gas exhaled by a human body is prevented from being inhaled and circulated again.

If the person moves vigorously, the second gear of the switch 11 is pressed, the fan is accelerated to operate, the negative pressure suction force is increased, air circulation is accelerated, waste gas discharged by the person due to the vigorous movement is discharged in time, air circulation is accelerated, and oxygen supply during the vigorous movement of the person is effectively ensured.

Compared with the circulating mask in the market, the active ventilation device is added, the circulation of air is accelerated, the waste gas is discharged in time, the breathing of the mask worn by a human body is smooth, and the motor is arranged to strengthen the gear, so that the oxygen supply during the severe movement of the human body is effectively ensured.

Compared with the prior art, the axial flow fan is changed into the centrifugal fan, so that the negative pressure suction pressure is further increased, the net-shaped bulge-shaped air inlet framework and the broken annular bulge are additionally arranged at the air inlet, the area of the air inlet is increased, and the phenomenon that the air circulation is unsmooth due to the fact that the cheek skin or mask cloth is adsorbed by the negative pressure suction is effectively prevented, so that smooth breathing is effectively ensured when people wear the mask.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
