Description

Anti-smog mask

technical field

The utility model relates to a respiratory protection device, in particular to an anti-fog mask.

Background technique

With the development of industry and the popularization of private cars, the problem of urban air pollution is becoming more and more serious, especially the excessive PM2.5 content, which seriously affects the health of people traveling. Wearing a face mask is a common precaution to reduce inhalation of excessive harmful substances.

The most primitive mask is a medical integrated mask. The cover body is made of filter non-woven fabric material. Users rely on the filter function of the non-woven fabric to shield dust particles in the outside air. The cost is low, so it has been widely used in a certain range. However, there are also some defects in this mouth mask: the user needs to overcome the resistance of air passing through the mouth mask when breathing, so the user is required to breathe hard to inhale enough air when using it; Trapped in the mask, this not only blocks the entry of fresh air, but also makes a large amount of exhaust gas in the mask mixed with a small amount of fresh air to be inhaled into the lungs again. This lack of fresh air can make the weaker users feel sick and uncomfortable, especially the elderly and children with chronic respiratory diseases.

In order to enhance the air fluidity inside and outside the mask and reduce the breathing difficulty of mask users, people have designed a new type of mask with a fan device fixed on the mask, such as Sichuan Duochi Biotechnology Co., Ltd. applied for on December 10, 2014. , the publication number is CN104190014A, and the invention patent application titled "Cavity Mask with Oxygen Enhancement Function" discloses an air grid box with a miniature fan fixed on the inside of the mask body at a position corresponding to the mouth and nose of the person. , the micro fan inhales the air outside the mask, and after being filtered by the non-woven layer of the mask, it is sent to the mouth and nose of the respirator, so as to reduce the breathing difficulty of the user. But there is still a drawback in the mask of this structure: the fan directly blows the air to the mouth and nose of the person, which will cause a very uncomfortable oppressive feeling to the user. Make it difficult to breathe.

Later, people designed a mask with a breathing valve, such as the "coolflow (coolflow)" valve of 3M Company, which is used in a relatively high proportion on the market. However, this valve only slightly improves the comfort of the mask, as it still requires some breathing effort to force the valve open during exhalation. Furthermore, adding such a valve to a disposable mask would significantly increase the price of the mask, making it less competitive in the market.

There are also various powered air breathing assistance systems on the market, such as 3M's Versaflow and Powerflow 7900PF systems, but these systems are usually bulky, expensive and unsuitable for the consumer market. Various forms of powered respirators involving the use of electric fans to overcome the resistance of air to flow through filter elements are also described in US Patent Nos. 6,854,464, 7,464,705 and 4,233,972.

A kind of mouth mask is disclosed in US Patent No. 6,257,235, and described mouth mask has increased a fan to improve its breathability and comfort. However, this invention has many disadvantages, including: a. It requires a specially designed mask, which has an interface to ensure that the fan is safely fixed on the mask, which is not available in traditional masks on the market. That is to say, unless the disposable masks commonly used on the market are modified on a large scale, the invention will not be effectively applied; and in terms of actual needs, its cost performance is also far lower than other disposable masks. b. The fan is located at the bottom of the mask, which means that the hot air exhaled by the human body, those parts that are not immediately drawn out by the fan, will rise and be trapped at the top of the mask air chamber. c. The exhaled hot and humid exhaust air is directly blown to the mask, and the moisture and heat in it also remain on the filter medium of the mask, and finally mixed with the filtered fresh air and re-inhaled together. d. In order to ensure a certain degree of comfort, the mask is soft, and this may cause the fan to be too close to the user's face, thereby not providing enough space to ensure the normal operation of the fan.
