Description
The utility model relates to a kind of double-deck reverse saw profile of tooth mouth mask sealing strip.
Existing simple type mouth mask, as 8710 types that Minnesota Mining and Manufacturing Company produces, the disposable dust protective mask of imitated Minnesota Mining and Manufacturing Company of domestic Beijing Plastics Plate No. 13 etc. only seal by aluminum strip at nose, it can not be out of shape with the motion of facial muscle, and sealing property also can reduce when reaching headwork in a minute; Other position such as cheekbone below are only fastening by respirator belt, do not have other seal approach.The simple and easy mouth mask that has (as 1410 type mouth masks of U.S. Willson company production), comprise all dustproof, breathing mask, then the shape of face by the people is designed to different models, and the wearer needs to carry out the measurement of shape of face grade of fit by special instrument before use, could select suitable model.Not only increase the expense of the processing charges and the shape of face tester of mould, and expended tester and wearer's time.
The purpose of this utility model is: provide a kind of sealing effectiveness and shape of face grade of fit better, can have the dynamic seal (packing) effect with the facial muscle motion deformation, convenient and practical gauze mask.
The utility model is made up of bottom sealing strip and upper strata press strip.It is characterized in that: to being connected into an oval-shaped sealing ring, top seal bar and lower seal bar upper surface all have serrated slot to the bottom sealing strip by bottom top seal bar (1) and bottom lower seal bar (2); Be a upper strata sealing ring press strip (3) identical with bottom sealing ring shape above the ovaloid seal circle, the lower surface of upper strata sealing ring press strip has the serrated slot that matches with the lower seal bar; Be useful on the collar (4) that is connected with the top seal bar on lower floor's sealing ring press strip.
The utility model has the advantages that:
1. improved the sealing property of mouth mask;
2. can be out of shape with facial muscle, have dynamic sealing performance;
3. save production mould expense and tester expense;
4. save tester and wearer's testing time.
Introduce the utility model in detail below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 are the utility model assembly structure front view and side view;
Fig. 3, Fig. 4 are bottom top seal bar front view and side view;
Fig. 5, Fig. 6 are bottom lower seal bar front view and side view;
Fig. 7, Fig. 8 are upper strata seal trim strip front view and side view.
Wherein: 1-bottom top seal bar
2-bottom lower seal bar
3-upper strata seal trim strip
4-connects the collar
With reference to accompanying drawing, the utility model is made of bottom sealing strip and upper strata press strip 3, the bottom sealing strip is connected into an oval-shaped sealing ring by bottom top seal bar 1 and 2 pairs of bottom lower seal bars, has serrated slot on the sealing ring, and upper strata with matching seal trim strip also has serrated slot.Compress the upper strata seal trim strip during use, because the effect of serrated slot, can only one-way movement between upper strata press strip and the bottom sealing strip, be difficult for unclamping after compressing like this, can play good sealing function.
