Description of the Invention: [Technical Field] The present invention relates to a breathing mask, and more particularly to a non-invasive breathing mask. [Prior Art] For medically sleep-suppressed patients, a respiratory mask is usually used to cover the nose or snout of the patient to assist the patient in breathing or perfusing the patient's therapeutic gas to maintain the patient's physiological function. 'When the breathing mask is placed over the user's breathing, it is the two sides that are aligned with the user's person (nose mask type) or lip (nose and nasal mask type) and with the use The opposite sides of the nose bridge are applied with a reverse and pull-back tension to stabilize the breathing mask. >Reading Figures 1 and 2, a breathing mask in the invention patent No. 94111233, which is invented by the inventor, is suitable for connecting a U' with a cover for a user. a cover soap element 12 in the breathing chamber and in communication with the air supply cover, two upper positioning members 13 which are spaced apart from each other and are symmetrically fixed to the top member 12, and two positioning positioning members 14 respectively located on the two upper positioning positioning members 14 And a plurality of strips are respectively attached to the fixed headbands 15 of the upper and lower clamps 13, 14. The upper and lower positioning 4' fixed to the cover unit 12 by a phase interval and the fixed headband 15 extending from the upper and lower positioning members 13, 14 and engaged around the user's head. , #1 The user's ... t enables the beer suction mask 1 to cover the unit u hair: the nose 'and then allows a specific gas to be delivered to the user through the gas supply unit 11. 201018501 Although the breathing mask i can pass through the upper and lower positioning members. "With the ^ change ^ belt 15 to achieve the positioning effect, but the actual ± still have the following points. In order to achieve a better fixation effect, usually the two upper positioning members U are placed opposite the nose of the user And close to the lower edge position of the user's eyes and position the two lower members 14 in alignment with the user's person (nose mask type) or lip (nose and nasal mask type), when When the headband 15 is pulled back from the two lower positioning members 14, respectively, it will bypass the ear of the manufacturer. When the headbands 15 are pulled back from the two upper positioning members 13, respectively, they will be clamped. Part of the user's eyes, the existing breathing mask! has the disadvantage of being worn poorly. 1. Although the position of the two upper positioning members 13 can be changed, for example, the two upper positioning members 13 are slightly moved downward, then When the two headbands 15 are pulled back from the two upper positioning members 13, the user's eyes can be avoided. However, after the two upper positioning members 13 are displaced, the breathing force is relatively concentrated, which will cause the breathing. The fixing effect of the mask 1 is not good, and the secret is applied to the upper edge of the ear to cause use. 1 is another conventional breathing mask 2 having a cover unit 21, two lower positioning members 22 spaced apart from each other and symmetrically disposed on the cover unit 21, and one from the cover unit An upper positioning member 23 extending upwardly from the top end, the upper positioning member 23 has an extension strap 231 fixedly coupled to the cover unit, and two solid supports 4 extending from the extension strap 231 to the left and right respectively 232. The breathing mask 2 further has four headbands 24 extending rearward from the two fixing portions 232 of the two lower positioning members 22 and the upper positioning member 23 and fixed around the head of the user 201018501. The lower positioning member 22 and the upper positioning member 23, and the headband 24 connected to the upper and lower positioning positions (4) and 23, respectively, can be used to fix the breathing mask 2 and cover the nose of the user. Or the function of the snout, but in fact, the following points can be further improved: 1. Although the lower half of the cover can be prevented from yawing by the two lower positioning members 22, The position piece 23 is connected to the 2 early 70 21 top '# the breathing mask 2 is subject to When it is shaken or vibrated, the upper half may still be yawed, which also has the disadvantage that the existing respiratory mask 2 has a poor fixing effect. 1 The extension strap 231 of the upper member 23 extends through the user. m causes the user to wear the mask line range (10) to have the disadvantage that it is less comfortable when the call is made. The soap is worn and used. [Invention] The purpose of the present invention is to provide a maintenance. A breathing mask with a better level effect. ‘Easy and still able to,:: Two?

The wearer's discomfort is reduced. At the same time, the cover unit 6 can still be stably fixed through the connection position A = the configuration of the lower positioning member 72. In addition, the two lower positioning members 72 can also be designed to be identical except that the two upper positioning members 71 can be designed to extend and form a narrow gap with the ring frame 612 by the connecting rod and the portion 712. The type can be used to make the two lower (four) 82 avoid the position which is easy to cause the user to feel uncomfortable while being fixed around, and does not affect the stable fixing effect of the cover unit 6. The above-mentioned 'the respiratory mask 4 of the present invention can achieve the following effects and advantages', so that the object of the present invention can be achieved: 1. By designing the two upper positioning members 71 of the positioning unit 7 to the joint portion 712 and the connection The positions A are spaced apart, and the type of the connecting rods connected therebetween can directly pass through the lower positioning member 72 and the two connecting positions A on the ring frame 612 of the supporting frame 61, so as to achieve The cover unit 6 can still be stably fixed, and the two joint portions are arranged to prevent the eyes and ears from being positioned when the headband 81 is fixed to the user's head. Therefore, in addition to changing the connection position between the two upper positioning members 71 and the upper headband 81, the present invention can prevent the user from wearing the respiratory mask 4, and still can breathe. The mask 4 maintains a predetermined positioning function without causing a decrease in the positioning stability of the cover unit 6 due to a change in the biasing position of the upper upper band 81 acting on the upper upper member 71. The second upper positioning member 71 is configured to have a narrow gap between the two connecting rods 711 and the ring-shaped frame 612, so that the pulling force applied to the two engaging portions 712 passes through the two connecting rods 711. The joint position A forms an upward and downward tensile force component F11, F712, and the downward pulling force F2 of the two lower positioning members 72 against the ring frame 612 causes the shell unit 6 to be subjected to a symmetric and evenly distributed tensile force. And obtaining a stable positioning effect, so that when the user wears the respiratory mask 4, the line of sight is not affected and has a more comfortable wearing experience. However, the above is only a preferred embodiment of the present invention. The scope of the present invention is not limited by the scope of the invention, and the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are still within the scope of the invention. 1 is a perspective view showing a breathing mask in the patent No. 94113233; FIG. 2 is a side view showing the breathing mask of the patent for covering a user's Figure 3 is a perspective view showing another conventional breathing mask; 13 201018501 Figure 4 is a perspective view showing the breathing embodiment of the present invention.
