[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides Figure 1-8 A nasal pillow mask with adjustable connector angle is shown, comprising a mask body 1 , a connector 3 is inserted into the front of the mask body 1 , and a nasal pillow cushion 101 is provided on the back of the mask body 1 .

[0030] It should be noted that in the design of this solution, a through hole is opened in the middle of the mask body 1, and the connector 3 is inserted and connected to the front end of the through hole, and the nasal pillow cushion 101 is provided to facilitate the mask to be put on the user's mouth and nose, and the use of the cushion form is also convenient for fitting with the skin of the user's mouth and nose, thereby ensuring that the mask is more stable when used for breathing.

[0031] Also includes:

[0032] The wearing mechanism is sleeved on the outer wall of the mask body 1. The wearing mechanism is used to sleeve the strap to wear the mask body 1. The outer wall of the mask body 1 is provided with a card slot 102 at one end close to the front. The card slot 102 is used to sleeve the wearing mechanism;

[0033] Specifically, the wearing mechanism includes a card frame 2, which is sleeved on the outer wall of the mask body 1 and sleeved in the card slot 102. Both sides of the card frame 2 are fixedly connected with a hanging rope column 202.

[0034] Furthermore, the wearing mechanism also includes a traction hanging plate 201, which is fixedly connected to the top of the bracket 2, and is used for traction and restraint at the top of the head.

[0035] It should be noted that after the bracket 2 is clamped on the outer wall of the mask body 1, it is restrained by the clamping groove 102. After such operation and setting, the bracket 2 can be connected to the mask body 1. In this way, when using this mask, the wearing strap is passed through the traction hanging plate 201 and the hanging rope column 202, and then the mask is worn on the user's face.

[0036] The rotating connection mechanism is arranged between the connection head 3 and the mask body 1. The rotating connection mechanism includes a seal 4 and an insertion tube 5. The insertion tube 5 is inserted and connected with the middle part of the seal 4. The insertion point of the insertion tube 5 and the seal 4 is provided with a positioning structure for rotational positioning.

[0037] Specifically, a connecting tube 301 is provided at the top of the connecting head 3, and the top of the connecting head 3 is fixedly connected to one end of the insertion tube 5. A through hole 401 is provided in the middle of the sealing member 4. The top of the connecting head 3 and the insertion tube 5 are both through-connected with the sealing member 4 through the through hole 401. The sealing member 4 is sleeved on the front of the mask body 1, and the positioning structure realizes the positioning operation in the through hole 401.

[0038] It should be noted that the seal 4 is inserted and connected to the through hole of the mask body 1 to seal the through hole, and ventilation is carried out through the through hole 401. In this way, the connector 3 serves as a ventilation channel, and the connector 3 serves as a ventilation channel and is inserted into the interior of the mask body 1 through the insertion tube 5, thereby forming a ventilation channel of the mask body 1.

[0039] It should be noted that

[0040] Furthermore, the positioning structure includes:

[0041] Positioning grooves 402, a plurality of positioning grooves 402 surrounding the inner ring wall of the through hole 401;

[0042] Positioning plug blocks 501 , multiple positioning plug blocks 501 are connected to the outer wall of the insertion tube 5 around the insertion block 5 , and the front surfaces of the multiple positioning plug blocks 501 are provided with locking inserts 502 , which are slidably inserted into the positioning groove 402 .

[0043] It should be noted that by interlacing the locking insert 502 with the positioning grooves 402 at different positions, the rotational position of the insertion tube 5 and the through-hole 401 is locked. Through such a structural setting, the rotation angle of the connector 3 is locked, thereby realizing the use of the connector 3 after the angle is rotated.

[0044] Furthermore, limiting grooves are provided on the inner walls on both sides of the insertion point of the positioning block 501 and the insertion tube 5, and multiple elastic balls 504 are provided between the insertion point of the positioning block 501 and the insertion tube 5. Limiting sliders 503 are fixedly connected on both sides of the positioning block 501, and multiple limiting sliders 503 are respectively slidably inserted and connected in the limiting grooves.

[0045] It should be noted that the elastic ball 504 is a hollow rubber ball, which has deformation characteristics and is elastic. Therefore, under the setting of the elastic ball 504, the positioning block 501 always moves in the direction away from the insertion tube 5, so that the positioning block 501 drives the locking insert 502 to be inserted into the positioning groove 402, thereby ensuring that the positioning structure can maintain the rotational lock of the insertion tube 5.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
