Description

Mask structure

The present invention relates to a mask structure that is simple in structure, can effectively filter and produce clean air.

With the development of the industry, various types of environmental pollution have occurred, and air pollution is the most sensitive. Wearing masks is the most basic protective measure in the face of deterioration of air quality. There are many types of masks, which are classified according to the material of the mask and the filtering ability. Common mask types include surgical masks, activated carbon masks, and N95 masks. The common use of various types of masks is that the elastic rope is hooked around the wearer's ears, so that the mask is closely attached and covered on the wearer's mouth and nose, and the mask is filled in the middle of the two sides of the cloth body. A layer of cotton yarn, by which the cotton layer is installed, can isolate impurities in the air. In this way, in addition to being able to block or filter the external harmful substances through the mask, the probability that the external harmful substances directly enter the human body from the gap between the mask and the wearer can be reduced.

Although the conventional mask can effectively filter the smoke and dust in the air, the flue gas and dust contained in the inhaled air are first filtered to provide a relatively clean air for the human body because it relies on the lungs of the human body to breathe. However, due to the limited amount of breathing in the human lungs, in order to avoid affecting the smooth breathing, the thickness and compactness of the mask filter layer are limited, so that the filtration effect and the amount of filtered air cannot be fully enhanced. Moreover, after wearing the mask, the coverage of the covered part is not good, causing the user's face to feel sultry and uncomfortable, which is why people know the pollution. Gas is harmful to the human lungs and is still reluctant to wear masks, which seriously reduces the willingness to use.

In view of this, the creator has made great efforts to study the existence of this creation in view of the existing shortcomings.

The main purpose of this creation is to provide a mask structure that is simple in structure, can effectively filter and produce clean air.

For the above purposes, a mask structure is provided in the present invention, comprising a body having a front end for covering a user's nose and mouth and a rear end portion for being fixed to the user's head and connected to the front end portion. Wherein, a middle cover is disposed at a middle portion of the front end portion, and left and right wing portions are disposed at both ends of the outer cover portion, and the left and right wing portions are in communication with the outer cover portion, wherein a fan filter device is disposed in the left wing portion, thereby The air in the front end portion of the main body can enter from the left wing portion, be purified by the fan filter device, and discharged into the outer cover to be used by the user, and then discharged from the right wing portion; and the right wing portion is further provided with a driving device for driving the The circuit device and the power device of the fan filter device in the left wing portion are further connected to a detecting device for detecting the air pressure in the outer cover to activate the circuit device to control the rotation speed of the fan filter device at any time.

In implementation, a fitting portion for tightly conforming to the face of the user is disposed around the front end portion of the body.

When implemented, the rear end of the body is a movable adjustable joint.

In implementation, the fan filter device includes a fan and a filter mesh.

In order to further understand the present invention, the preferred embodiments of the present invention, together with the drawings and figure numbers, detail the specific components of the present creation and the effects achieved thereby.

Fig. 2 is a partially exploded perspective view showing another embodiment of the mask structure in the present embodiment.

Fig. 3 is a schematic view showing the appearance of the mask structure in the present embodiment.

Please refer to FIG. 1-3, which is a specific embodiment of the structure of the present invention, which includes a body 1 having a front end portion 11 for covering a user's nose and mouth and a fixing for the user's head. The end portion 12 is connected to the front end portion 11.

A front end portion 11 of the body 1 is provided with a fitting portion 111 for closely fitting to the face of the user. The rear end portion 12 is a movable adjustable joint for fixing to the user's head. The coupling member can be designed as an elastic band or a combination that is combined in a snap-fit manner. An outer cover 13 is disposed at a middle portion of the front end portion 11, and left and right wing portions 14, 15 are disposed at both ends of the outer cover portion 13, and the left and right wing portions 14, 15 are in communication with the outer cover 13 and the left wing portion 14 is therein. A fan filter device 2 is provided. The fan filter device 2 includes a fan 21 and a filter mesh 22. The right wing portion 15 is further provided with a circuit device 3 for driving the fan filter device 2 in the left wing portion 14. And the power device 4, the circuit device 3 is further connected to a detecting device 5 for detecting the air pressure in the outer cover 13 to activate the circuit device 3 to control the rotational speed of the fan 21 in the fan filtering device 2.

Therefore, when the creation is started, the air of the front end portion 11 of the main body 1 can be driven by the fan 21 of the fan filter device 2 in the left wing portion 14 to be sucked from the left wing portion 14 and passed through the filter mesh of the fan filter device 2. After purging the air, the air is discharged into the outer cover 13 for use by the user, and finally the gas exhaled by the user is discharged from the right wing portion 15. The detecting device 5 in the right wing portion 15 can detect the air pressure in the outer cover 13 at any time to activate the circuit device 3 to control the fan 21 turn at any time. The speed is adjusted to timely adjust the flow of air into the outer cover 13.

Therefore, this creation has the following advantages:

1. This creation utilizes the fitting portion provided around the front end portion of the main body to closely fit on the user's face, reducing the discomfort caused by the conventional cotton mask covering the nose and mouth, and guiding it through the fan. The airflow can increase the coolness of the nose and mouth, thus increasing the user's willingness to wear.

2. This creation uses the fan of the fan filter device to attract and purify the air through the filter mesh, just like a small air quieter, so that the clean air is continuously introduced into the outer cover, and the detection device is detected to adjust the time to enter the The air flow in the left wing provides the user with the most comfortable breathing environment.

The foregoing is a specific embodiment of the present invention and the technical means employed, and many variations and modifications can be derived therefrom based on the disclosure or teachings herein, and can still be regarded as equivalent changes made by the inventive concept. The role of the spirit and the spirit of the text and the scope of the text should be considered within the technical scope of this creation.

In summary, according to the content disclosed above, this creation can achieve the new intended purpose, provide a mask structure, which is of great value for industrial use, and proposes a new type of patent application according to law.
