DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 5 In an embodiment of the present invention, a reverse-wrapped capsule 100 includes a capsule body 10 , a capsule seat 20 and an air guide ring 30 .

[0024] The capsule body 10 is provided with a right port portion 11 and a left port portion 12 at both ends. The capsule seat 20 includes: a seat body 21 for being mounted on the capsule mounting spindle 200 and a mounting pressure cap 22 for fixing the capsule body 10. The mounting pressure cap 22 is detachably mounted to the end of the seat body 21. The seat body 21 includes: an integrally formed column portion 211 and a positioning plate portion 212. The positioning plate portion 212 is located on the outer periphery of the column portion 211. The column portion 211 passes through the right port portion 11 and the left port portion 12. The inner hole walls of the right port portion 11 and the left port portion 12 are in contact with the outer wall surface of the column portion 211. The positioning plate portion 212 is formed with a right limiting groove 2121 for the right side of the right port portion 11 to be embedded. The mounting pressure cap 22 is formed with a left limiting groove 221 for the left side of the left port portion 12 to be embedded. The air guide ring 30 is sleeved on the column portion 211 and is located between the right port portion 11 and the left port portion 12. When the mounting cover 22 is fixed to the seat body 21 , the mounting cover 22 and the air guide ring 30 abut and press the left port portion 12 from both sides, and the positioning plate portion 212 and the air guide ring 30 abut and press the right port portion 11 from both sides.

[0025] The inner wall of the air guide ring 30 is formed with an air guide ring groove 31. The air guide ring 30 also has multiple radial air guide holes 32. One end of each radial air guide hole 32 communicates with the air guide ring groove 31. The other end of each radial air guide hole 32 communicates with the interior of the capsule body 10. The seat body 21 is provided with several air guide channels 2111, which connect to the air guide ring groove 31.

[0026] As a specific implementation, the plurality of radial air guide rings 30 are evenly distributed around the axis of the air guide ring 30 .

[0027] As a specific embodiment, a left notch groove is formed on the left side of the right port portion 11 for the right end of the air guide ring 30 to be embedded in. A right notch groove is formed on the left side of the left port portion 12 for the left end of the air guide ring 30 to be embedded in.

[0028] As a specific embodiment, the right limiting groove 2121 and the left limiting groove 221 are symmetrically arranged. The right port portion 11 and the left port portion 12 are symmetrically arranged.

[0029] As a specific embodiment, the right port portion 11 and the left port portion 12 are both formed with an outer conical surface on the side away from the air guide ring 30. The positioning plate portion 212 and the mounting cover 22 are both formed with an inner conical surface that matches the outer conical surface.

[0030] As a specific implementation, in the radial direction of the capsule seat 20 , the outer wall surface of the air guide ring 30 is located between the top and the bottom of the inner conical surface.

[0031] During installation, the right and left port portions 11, 12 of the capsule body 10, together with the air guide ring 30, are fitted onto the column portion 211 of the seat body 21. The mounting gland 22 is then installed, and the mounting gland 22 is used to lock the positions of the right and left port portions 11, 12. Due to the presence of the air guide ring 30, it abuts against the inner sides of the right and left port portions 11, 12, thereby locking the outer sides of the right and left port portions 11, 12 into the right and left limiting grooves, respectively.

[0032] The specific structure of the right limit groove 2121 and the left limit groove 221 and the structural setting of the right port portion 11 and the left port portion 12, together with the air guide ring 30, realizes locking of the right port portion 11 and the left port portion 12 in four directions, with high locking reliability. When pressure is applied axially, the conical surface is squeezed and deformed to make the right port portion 11 and the left port portion 12 fit into the embedded groove and the column portion 211 to improve the sealing performance.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
