Detailed Description

For the convenience of understanding of those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the personal fresh air device disclosed in this embodiment has the advantages of smooth and easy breathing, and is suitable for various people.

Specifically, the personal fresh air device comprises a cover body 1 and a binding band 5 covering the mouth and the nose of a human body, wherein an independent air inlet 2 and an independent air outlet 3 are arranged on the cover body 1, a filter layer 21 and an air inlet blade 22 are arranged in the air inlet 3, and a one-way valve 31 is arranged in the air outlet 3. The vanes 22 can be light and low-noise vanes, the air inlet vanes 22 are driven by the motor 4, and the motor 4 is powered by the battery 41. A check valve 31 is also provided in the outlet 3. When the mask is used, the motor 4 drives the blades 22 to work, the blades 22 enable gas to enter a space between the mask body 1 and the face of a human body from the outside through the filter layer 21, certain pressure is provided for the space, the problem that the existing mask gas can only be inhaled by the lung of the human body through the filter layer to cause difficulty in inhalation is solved, and smoothness and easiness in inhalation are guaranteed.

The air inlet blade 22 and the motor 4 in this embodiment are installed in the frame 23, the frame 23 is connected or clamped to the air inlet 2 through threads, an air inlet end cover 24 is installed at the outer end of the frame 23, and the air inlet end cover 24 is connected or clamped to the end of the frame 23 through threads. The air inlet end cover 24 is provided with a through hole, and the filter layer 21 is clamped between the end part of the air inlet 2 and the inner wall of the air inlet end cover 24. This structure makes filter layer 21 very convenient to detach change, only needs pull down the inlet end cover and can take out the filter layer, is convenient for change the filter layer of different grade type according to the occasion needs of difference, for example satisfy medical requirement's medical filter layer or the PM2.5 filter layer of antifog haze or melt various filter layers such as the cloth filter layer of spouting, the filter layer that has the function of disinfecting. Moreover, the whole air inlet part is integrally detached from the cover body by the structure, so that the cleaning is facilitated.

The check valve in this embodiment includes a valve body 311 clamped in the air outlet, a partition plate 312 is provided in the valve body 311 in the radial direction, a vent hole 313 is provided on the partition plate 312, a flexible silicone sheet 314 covers the outer surface of the partition plate 312, and the middle part or one point of the silicone sheet 314 is fixed on the partition plate 312. The silica gel piece lifts up and makes the air current pass through the air vent when exhaling, and the silica gel piece closely covers 13 when breathing in and prevents that the air current from getting into on the air vent, is provided with air-out end cover 315 at the outer tip of valve body, and the battery that is used for driving motor is located air-out end cover, is connected with the motor that is located air inlet end cover through the wire, is provided with through-hole 316 on air-out end cover.

The cover body adopted by the embodiment can be of an integral structure of soft silica gel or hard plastic.
