Technical Field

The invention relates to the field of protective articles, in particular to a disposable mask.

Background

The mask is a sanitary article, and is generally a tool which is worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to prevent harmful dust, gas, smell and spray from entering and exiting the mouth and nose of a wearer. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like.

At present, the gauze mask on the market is usually made by adopting breathable fabrics such as gauze and filling certain air filtering materials, the gauze mask needs to be discarded after being used for a certain number of times or being used for one time, the use cost is higher, especially under some severe environments (such as construction sites with heavier dust and chemical plants with heavier peculiar smell), the use of the gauze mask is more frequent, the number of times of using a single gauze mask is less, the use cost is higher, meanwhile, the existing gauze mask is blocked by the fabrics and the air filtering materials when being used, the user has breathing difficulty to a certain extent, and the gauze mask is more severe under the severe environment.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the disposable mask which has a simple structure, does not need to be discarded, greatly reduces the use cost and simultaneously reduces the breathing difficulty of a user.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a disposable mask comprises an air filter box, a mobile power supply and a mask body with a sealed mask surface;

a fan which divides the air filter box into an air inlet cavity and an air outlet cavity is arranged in the air filter box, one end of the air inlet cavity, which is far away from the fan, is open, an air filter assembly is detachably arranged in the air inlet cavity, and the fan extracts air filtered by the air filter assembly in the air inlet cavity and enters the air outlet cavity;

the mobile power supply is electrically connected with the fan through a line so as to supply power to the fan;

the mask body with be equipped with the breather pipe between the ventiduct, the one end intercommunication of breather pipe the ventiduct, the other end is from outer to interior to pass the mask body and feed through the inboard of mask body, the nasal part below of mask body is installed the intercommunication the check valve of the gauze mask body inside and outside, the check valve by this internal outside one-way opening of gauze mask.

Furthermore, an opening is formed in the top of the air filter box corresponding to the air filter assembly, a cover plate capable of opening and closing the opening is arranged at the opening, and the air filter assembly can be detached from or installed in the air inlet cavity through the opening after the cover plate is opened.

Further, the air filter assembly includes a plurality of air screens distributed along an airflow direction of the intake chamber.

Further, the air filter screen is equipped with five, and by outer and interior first way and second way be the colating filter screen, third way and fourth way are fine filter screen and fifth way is for removing the flavor filter screen.

Further, the rough filtration filter screen is a stainless steel filter screen, the fine filtration filter screen is a HEPA filter screen, and the odor removal filter screen is a HACF filter screen.

Furthermore, the inner walls of the two sides of the air inlet cavity correspond to the air filter screens, mounting clamping grooves are formed in the air filter screens respectively, and the two ends of each air filter screen are located in the corresponding mounting clamping grooves respectively and are matched with the groove walls of the mounting clamping grooves in a damping mode.

Further, the outer side of the cover plate is hinged with a pull ring.

Furthermore, a damping rubber is fixed on the circumferential side wall of the cover plate.

Further, the fan adopts a 12V micro fan.

Furthermore, the outer walls of the two sides of the air filter box are respectively provided with the hanging buckle and the accommodating groove which protrude out of the air filter box.

The invention has the beneficial effects that:

1. for the fan power supply through portable power source, the fan extraction is admitted air the intracavity and is gone out the air cavity through the filterable air admission of filtration subassembly, then it provides fresh and clean air to breathe in for the user through breather pipe inlet cowling body inboard, when the user exhales, the foul smell of exhalation is inboard via check valve discharge gauze mask body, and back-up after wasing through regularly pulling down the filtration subassembly, avoid abandoning the gauze mask body, moreover, the steam generator is simple in structure, greatly reduced use cost, and extract external air and to the inboard air feed of gauze mask by the fan, reduce user's breathing difficulty.

2. The air filter box can be arranged at a position relatively far away from a pollution source by virtue of the length of the vent pipe, so that the open end of the air inlet cavity avoids the pollution source to the maximum extent, and the air filter box can filter air with half the effort.

3. Because the mask surface of the mask body is closed, the mask body can be made of firm and durable leather, silica gel and other materials, so that the service life of the mask body is prolonged.

4. The air is through twice colating, twice fine filtration and one remove the flavor filtration processing, and the user can the more clean air of free from extraneous odour of respiratory track, ensures that the user uses this gauze mask safe and reliable under different environment.

5. The air filter box can be hung on a belt or a waistband of the waist of a user or other suitable hanging positions by utilizing the hanging buckle, so that the air filter box is more convenient to carry.
