DETAILED DESCRIPTION

[0028] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] See also Figures 1 to 3. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of this utility model. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by this utility model without affecting the efficacy and purpose that can be achieved by this utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0030] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0031] See also Figure 1 、 2 The utility model provides an underwater breathing sealing device for Bama pigs, comprising a sealing shell 1 and an inflatable seal 2; the inflatable seal 2 is a circular elastic deformation structure, which is arranged on the annular inner wall of the sealing shell 1; the sealing shell 1 is provided with a sealing valve 3 for connecting with the inflatable seal 2, and the sealing valve 3 is used to inflate or deflate the inflatable seal 2. Specifically, a through hole is provided on the sealing shell 1, and the sealing valve 3 passes through the through hole and is connected to the inflatable seal 2. When in use, the sealing shell 1 is put on the pig's mouth, and the inflatable seal 2 can be inflated by using the sealing valve 3 with an air pump. During the inflation process, the inflatable seal 2 undergoes elastic deformation, first coming into contact with part of the skin of the pig's mouth, and then, due to the continuous inflation of the inflatable seal 2, the elastically deformed part of the inflatable seal 2 gradually fills the wrinkles on the skin of the pig's mouth, and then clings to the pig's mouth to achieve sealing of the pig's mouth. After use, the gas in the inflatable seal 2 is released by using the sealing valve 3 to facilitate the removal of the underwater breathing seal device from the pig's mouth.

[0032] The inflatable seal 2 includes a connecting portion 21 and a sealing portion 22. The connecting portion 21 and the sealing portion 22 together form a gas-containing chamber 23. The sealing valve 3 is connected to the chamber 23 through a through-hole provided in the sealing housing 1. A mounting structure for mounting the connecting portion is provided on the annular inner wall of the sealing housing 1. In this embodiment, the mounting structure is a convex groove provided on the annular inner wall of the sealing housing 1. The convex groove is arranged around the inner wall of the sealing housing 1, with the small end of the convex groove facing the inner side of the sealing housing 1. It is understood that the connecting portion 21 of the inflatable seal 2 is also configured as a convex structure to prevent the inflatable seal 2 from detaching from the fixed portion due to the expansion of the chamber 23 during inflation. Of course, the mounting structure can also be, for example, an arc-shaped groove around the inner wall of the sealing housing 1. During installation, the connecting portion is set within the arc-shaped groove by gluing or other methods. This is not limited to this invention.

[0033] The cross section of the sealing portion 22 of the inflatable seal 2 is an arc-shaped, and its central angle is greater than or equal to 180° and less than or equal to 270°; its central angle can be 190°, 200°, 210°, 220°, 230°, 240°, 250°, or 260°. When the central angle of the sealing portion 22 is greater than or equal to 180° and less than or equal to 270°, the contact area between the sealing portion 22 and the pig's mouth skin is larger, further ensuring that the sealing portion 22 can fill the wrinkles on the pig's mouth skin, achieving the best sealing effect. At the same time, it can also ensure that the connecting portion 21 of the inflatable seal 2 will not detach from the fixing portion during the inflation process.

[0034] like Figure 3 As shown, the sealing valve 3 includes an air nozzle 31, an elastic member 32, and an air flow baffle 33. The air nozzle 31 is connected to the accommodating chamber 23 of the inflatable seal 2 through a through-hole provided in the sealing housing 1. A first abutment 311 is provided on the inner end of the air nozzle 31, closer to the inflatable seal 2, and a second abutment 312 is provided on the inner end of the air nozzle 31, further away from the inflatable seal 2. One end of the elastic member 32 is connected to the first abutment 311, and the other end is connected to the second abutment 312 via the air flow baffle 33. The arrangement of the first abutment 311 and the second abutment 312 secures the elastic member 32 within the air nozzle 31. When inflating the inflatable seal 2, the end of the air pump's needle abuts the air flow baffle 33, which then causes the elastic member 32 to elastically deform, causing the air flow baffle 33 to disengage from the second abutment 312, allowing the air pump to be used to inflate the inflatable seal 2. After inflation is complete, the air pump needle is removed and the elastic force of the elastic member 32 is used to connect the airflow baffle 33 to the second abutment portion 312, thereby sealing the inflatable seal 2 and preventing air leakage. In this embodiment, the elastic member 32 is a spring, but it can also be other elastic components as long as it can maintain the connection between the airflow baffle 33 and the second abutment portion.

[0035] The sealing valve 3 also includes a sealing ring 34, through which the airflow baffle 33 is connected to the second abutment portion. The provision of the sealing ring 34 enhances the sealing effect between the airflow baffle 33 and the second abutment portion 312, further preventing air leakage. A flow guide 331 is provided on the side of the airflow baffle 33 near the second abutment portion 312 to guide the flow of gas. The flow guide 331 is conical in shape, with its small end facing the outside of the sealing housing 1. The provision of the flow guide 311 guides gas during the inflation and deflation of the inflatable seal 2, thereby improving its efficiency.

[0036] The underwater sealing device also includes a first seal 4, which is connected to the sealing shell 1. The first seal 4 is made of an elastic material, such as neoprene. When in use, the elastic deformation of the first seal 4 can be used to make the first seal 4 fit tightly to the pig's mouth, and also fill the wrinkles on the pig's mouth skin to further ensure the sealing effect. In one implementation, waterproof silicone grease is provided on the inner wall of the first seal 4. When in use, the waterproof silicone grease is filled into the wrinkles of the pig's mouth skin, and then the synergistic effect of the first seal 4 and the inflatable seal 2 is utilized to further ensure the sealing effect. It can be understood that the waterproof silicone grease can be applied to the inner wall of the first seal 4 when in use, or it can be directly provided on the first seal 4. The present solution does not impose any restrictions on this.

[0037] In one implementation, the end of the sealing shell 1 away from the first sealing member 4 is tapered along its axial direction, that is, the diameter of the end of the sealing shell 1 away from the first sealing member 4 gradually decreases and becomes trumpet-shaped, which better fits the pig's mouth.

[0038] In one implementation, the sealed housing 1 further includes a second seal 5, which is spaced apart from the inflatable seal 2 within the sealed housing 1. Multiple second seals 5 may be provided, with the plurality of second seals 5 spaced apart within the sealed housing 1. In this embodiment, the second seal 5 is an O-ring disposed within the sealed housing 1. The arrangement of the first seal 4, the inflatable seal 2, and the second seal 5 ensures a secure seal for the respiratory mask by connecting to the pig's snout at various locations within the snout.

[0039] The present invention further provides a breathing mask comprising the aforementioned underwater breathing seal device, and further comprising a connector 6 for connecting to an oxygen delivery tube. The connector 6 may be a sealed joint disposed on an end of the sealed housing 1 remote from the first seal 4 and connected to the oxygen delivery tube, thereby connecting the breathing mask to the oxygen tank. Of course, the connector 6 may also have other structures, which are not limited by the present invention, as long as the breathing mask can be connected to the oxygen tank and oxygen in the oxygen tank can be delivered to the breathing mask.

[0040] Working principle: When in use, waterproof silicone grease can be applied on the inner wall of the first seal 4 first, and then the breathing mask can be put on the pig's mouth. At this time, the first seal 4, the second seal 5 and the waterproof silicone grease applied on the first seal 4 work together to seal the pig's mouth. Then the inflatable seal 2 is inflated, and the sealing part 22 of the inflatable seal is filled into the folds on the skin of the pig's mouth, thereby further sealing the pig's mouth. At the same time, the valve on the oxygen tank is opened to enable the Baxiang pig to breathe underwater to maintain its life characteristics. After use, the inflatable seal 2 is first deflated, and the breathing mask can be removed from the pig's mouth after deflation is completed.

[0041] In summary, the present invention utilizes an inflatable seal 2 to fill wrinkles in the pig's snout, preventing water from entering the mask or oxygen from leaking due to these wrinkles. Furthermore, the first seal 4, the inflatable seal 2, and the second seal 5 work together to seal at different locations within the pig's snout, further ensuring the mask's sealing effectiveness. Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
