Advantageous effects

Compared with the prior art, the utility model discloses a variable motion face guard of resistance's advantage does:

1. the first air suction hole and/or the second air suction channel of the sports mask are/is provided with a filter layer. When people wear the mask to move, even if the surrounding air contains fine particles, the filter layer on the moving mask can also block the fine particles to avoid being inhaled by people, and the respiratory system of people is effectively protected from being hurt by the fine particles.

2. Because the filter layer is the consumable article, through setting up the filter layer between the inner chamber bottom of regulating part main part and lid, pull down the lid and can change the filter layer, convenient operation is swift. And the filter layer is placed in the inner cavity of the adjusting part main body, and can be fixed without glue, so that the use of chemicals is reduced, and the environment is protected.

3. The bottom of the inner cavity of the regulating part main body is provided with a reinforcing rib, one end of the reinforcing rib is connected with the outer side wall of the cylindrical second expiration channel, the other end of the reinforcing rib faces the side wall of the inner cavity, the rigidity and the strength of the regulating part main body are improved, and the problem that the breathing resistance regulating part deforms due to repeated use and the air tightness is poor is avoided.

4. The convex part at the outer edge of the cover body is clamped with the clamping groove of the adjusting piece main body. Because at least one of them bellying sets up on the elastic component of lid outward flange, when needing to install the lid to the regulating part main part, only need to press the bellying that sets up in the elastic component toward the lid middle part, put into the inner chamber of regulating part main part with the lid whole again, loosen the elastic component, let the bellying of each lid all stretch into the draw-in groove of regulating part main part in, can realize the joint of lid and regulating part main part. The mode does not need to press the cover body into the inner cavity of the adjusting part main body by force, is convenient to operate and is not easy to cause part damage.

5. At least one of the first air suction hole and the second air suction channel comprises a thin strip-shaped groove and a wide strip-shaped groove, one ends of the thin strip-shaped groove and one end of the wide strip-shaped groove are mutually communicated, and the width of the thin strip-shaped groove is smaller than that of the wide strip-shaped groove. Providing a filter layer reduces air throughput. In order to make the product suitable for professional athletes and common sports enthusiasts, one section of the strip-shaped groove is widened into a wide strip-shaped groove. When the sports mask is set to be in a state with small resistance (namely the wide strip-shaped groove is conducted), enough air throughput can still be ensured, and the problem that common sports enthusiasts feel too difficult to breathe in use is avoided. For professional athletes, when the sports mask is set to be in a state with large resistance (namely, the thin strip-shaped groove is conducted), even if the width of the conducted strip-shaped groove is small, the athletes can bear the resistance.

The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings which illustrate embodiments of the invention.
