Description

Technical Field

[0001] The utility model relates to the technical field of air breathing masks, in particular to a spherical mask of an air respirator which improves the air tightness of the mask when worn on the head and face of a human body. Background Art

[0002] There are two major standards for air respirators in my country, GB16556 self-contained open-circuit compressed air respirator and XF124 positive pressure fire-fighting air respirator. Both use bottled compressed air as the gas source. The gas is transported to the mask after decompression and supplied to the mask device that fits tightly with the human head and face for oral and nasal breathing. The technical point of the mask is that it must fit closely with the human head and face to isolate the clean air in the mask from the operating pollution or harmful gas environment outside the mask to ensure the safety of personnel. The seal helps prevent the clean air in the mask from leaking out, thereby extending the working time of users. The current air breathing masks still have certain shortcomings.

[0003] Please refer to the announcement number CN219517607U, which is an air respirator mask suitable for myopic people. When the wearer wears the respirator mask body, it is not worn over the wearer's ears, so that it is convenient for the subsequent wearing of frame glasses on the upper end of the ears. The frame glasses can also be limited in position inside the transparent mounting frame for use, so that the myopic people can use the respirator mask body.

[0004] However, in the above patent, there is no soft component at the lower jaw of the mask that fits the user's face. After the user wears the mask for a long time, the face sweats and slips, the oral muscles move, and the head swings irregularly during human labor, which causes the mask to move, thereby causing the mask to leak and reducing the sealing of the mask. This application proposes a technical solution to solve this technical problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a spherical mask for an air respirator that improves the air tightness of the human head and face. The mask has the advantages of improved sealing and solves the problem that after the user wears the mask for a long time, the face sweats and slips, the oral muscles move, and the head swings irregularly during labor and exercise, which causes the mask to shift, thereby causing the mask to leak and reduce the sealing of the mask.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spherical air respirator mask for improving the air tightness of the human head and face, comprising a mask body, a supporting mesh frame, and a connecting component installed between the mask body and the supporting mesh frame;

[0007] The connecting component includes a first elastic strap and a second elastic strap fixedly installed on one side of the supporting mesh frame, a soft colloid fixedly installed inside the mask body, and a first buckle component and a second buckle component fixedly installed at the expanded areas of the left and right lower jaws of the soft colloid strip.

[0008] By adopting the above technical solution, the wearing tightness between the mask body and the human head and face in various states is significantly improved, and the slipping and displacement between the mask body and the human facial skin after a large amount of sweating on the human face is reduced.

[0009] Optionally, the other end of the first buckle assembly is fixedly connected to the first elastic strap.

[0010] By adopting the above technical solution, the first buckle assembly and the first elastic strap are used in combination to facilitate fixing the mask body on the user's face.

[0011] Optionally, the other end of the second buckle assembly is fixedly connected to the second elastic strap.

[0012] By adopting the above technical solution, through the cooperation of the second buckle assembly and the second elastic band, the soft colloid is attached to the two sides of the oral cavity, so that the soft colloid forms a surface seal with the skin of the two cheeks.

[0013] Optionally, the left and right lower jaws of the soft colloid are provided with connection holes for fixed connection of the first buckle assembly and the second buckle assembly.

[0014] By adopting the above technical solution, it is convenient to pull the soft colloid backwards on both sides of the oral cavity during use, so that the soft colloid forms a surface seal with the skin of both cheeks, thereby improving the use effect of the mask.

[0015] Optionally, an air supply valve is fixedly installed on the outside of the mask body, and a sealing cover is fixedly installed on the inside of the mask body.

[0016] By adopting the above technical solution, the sealing performance of the mask body is further improved, and the safety of the use of the mask body is improved.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The spherical mask of the air respirator for improving the air tightness of the human head and face is installed with a connecting component, which significantly improves the wearing tightness between the mask body and the human head and face in various states, reduces the slipping displacement between the mask body and the human facial skin after a large amount of sweating on the human face, improves the tight fit and air tightness between the mask and the facial skin under the random swinging, shaking and collision of the head in medium and high intensity exercise and labor, and improves the use effect of the mask.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 In this embodiment, a spherical air respirator mask for improving the air tightness of the human head and face includes a mask body 1, a supporting mesh frame 2, and a connecting component installed between the mask body 1 and the supporting mesh frame 2.

[0025] In this embodiment, the connecting assembly includes a first elastic strap 3 and a second elastic strap 4 fixedly installed on one side of the supporting mesh frame 2, a soft colloid 5 fixedly installed inside the mask body 1, and a first buckle assembly 6 and a second buckle assembly 7 fixedly installed at the enlarged areas of the left and right lower jaw areas of the soft colloid 5.

[0026] The left and right lower jaws of the soft colloid 5 are provided with connection holes 501 for fixed connection of the first buckle assembly 6 and the second buckle assembly 7. The soft colloid 5 is partially lengthened and widened at the human cheeks to facilitate the two sets of tightening points of the soft colloid 5. The soft colloid 5 is pulled back on both sides of the oral cavity to form a surface seal with the user's cheek skin, thereby reducing the displacement and leakage of the mask caused by facial sweating and slipping, oral muscle movement and irregular head swinging during human labor after the user wears the mask for a long time, thereby improving the use effect of the device.

[0027] The other end of the first buckle assembly 6 is fixedly connected to the first elastic strap 3, and the other end of the second buckle assembly 7 is fixedly connected to the second elastic strap 4, so as to facilitate sealing and fixing the mask body 1 to the user's face.

[0028] An air supply valve 8 is fixedly installed on the outside of the mask body 1, and a sealing cover 9 is fixedly installed inside the mask body 1. When in use, the external air supply pipe is connected to the air supply valve 8, and then oxygen is transmitted to the inside of the sealing cover 9.

[0029] The working principle of the above embodiment is as follows: when in use, the mask body 1 is fitted on the user's face, and the length of the first elastic strap 3 and the second elastic strap 4 is adjusted, and then the first buckle assembly 6 and the second buckle assembly 7 are matched to firmly fit the mask body 1 on the user's face. The two groups of tightening points on the mask body 1 form tightened rice noodles with the bones of the human head and face. The two groups of tightening points fit the soft colloid 5 with the two sides of the oral cavity, so that the soft colloid 5 forms a surface seal with the skin of the two cheeks. The soft colloid 5 and the cheek skin are both soft bodies. The tension on the soft colloid 5 keeps the two always in contact, and will not be displaced due to facial sweating and slipping, oral muscle movement and irregular head swinging during human labor and exercise, forming a 360-degree static and dynamic close fit between the mask and the human head and face, fully overcoming the disadvantages of the mask body 1 and the head and face under medium and high intensity labor and exercise, the soft colloid 5 slipping when the face sweats and the random swinging of the head, and ensuring the airtightness of the head and face and the mask body 1.
