Description

breathing mask

technical field

The invention relates to a breathing mask, in particular to a breathing mask for supplying positive pressure air to a user.

Background technique

Referring to Fig. 1, the existing breathing mask 11 includes a mask unit 111 that is arranged on the mouth and nose of a user 12, and a forehead support frame 112 that is installed on the mask unit 111 and is used to support the forehead of the user 12 In this way, a ventilation tube 13 installed on the mask unit 111 can be used to input positive pressure air into the breathing mask 11 for use by the user 12 .

When in use, the straps 14 are used to pass around the back of the head of the user 12 respectively from both sides of the forehead support frame 112 and the both sides of the mask unit 111. At this time, the tension applied by the straps 14 will Make this forehead support frame 112 and the both sides of this mask unit 111 be respectively fixed on the forehead of this user 12 and the inside of both cheeks, now the central part of this mask unit 111 just can cover this user's 12 nose and mouth And lean against the root of the nose of the user 12 with an abutting force.

However, since the size of the abutting force is related to the forehead shape, cheek shape and nose shape of the user 12, the straight line between the forehead and the cheeks is used as a reference line L, and the base of the nose is opposite to the nose shape. The user 12 with a relatively concave reference line bears less abutting force at the root of the nose, which will cause incomplete coverage of the breathing mask 11 and cause leakage of positive pressure air. The protruding user 12 bears a very large abutment force at the root of the nose, which will cause discomfort when worn and cannot be worn for a long time. Therefore, the same style of breathing mask cannot satisfy all the requirements of different forehead shapes, outer cheeks, etc. Type, and nose type users 12 use.

In addition, as disclosed in U.S. Patent No. 6,532,961, an adjustable breathing mask similar to the aforementioned breathing mask 11, the difference is that the forehead support frame includes a push-button against the forehead of the user, and a Installed between the mask unit and the push piece to adjust the adjustment joint of the push piece, the push piece changes the angle of the push piece relative to the mask unit with the adjustment of the adjustment joint, and is suitable for different Used by people with forehead height. However, this method does not change the position where the breathing mask is close to the root of the nose, and still cannot solve the problems caused when the breathing mask is close to the root of the nose, so it still cannot satisfy any user to obtain the most comfortable effect when wearing the breathing mask .
