[0041] Working principle:

[0042] In use, the male head sleeve and the female head sleeve are respectively connected with the liquid supply circuit and the liquid cooling circuit at the opposite ends thereof;

[0043] When the male head and the female head are separated:

[0044] The floating block in the male head sleeve moves to the second inner flange under the action of the male head spring and realizes sealing of the male head inner flow channel communicating with the liquid supply circuit through the third sealing ring, and the floating ring in the female head sleeve moves to the space between the upper flange part and the first inner flange under the action of the female head spring and realizes sealing of the female head inner flow channel communicating with the liquid cooling circuit through the first sealing ring and the second sealing ring.

[0045] The pressing part of the clasp moves away from the female head sleeve under the action of the first spring so that the clamping part thereon is located at the innermost end of the stroke, at the same time, the lower end of the rotating block rotates away from the female head sleeve under the action of the second spring so that the upper end thereof drives the movable block to move inward along the radial direction to the innermost end of the stroke, at this time, the second inclined surface on the clamping part of the clasp is flush with the third inclined surface on the rotating block, and the end surfaces of the respective ends of the clamping part and the rotating block are flush with the side wall of the first inner flange.

[0046] When the male head and the female head are mutually inserted:

[0047] The male sleeve moves downward into the female sleeve, and the outer surface of the male sleeve is in sliding contact with the side wall of the first inner flange in the female sleeve; the floating ring in the female sleeve is pushed downward by the male sleeve moving downward and compresses the female spring, and the floating block in the male sleeve is pushed upward by the upper end surface of the fixed support rod and compresses the male spring, at this time, the flow channels in the male and female sleeves are connected and communicated with each other;

[0048] When the protruding part on the male sleeve moves downward until the first inclined surface on the protruding part is in contact with the second inclined surface and the third inclined surface that are flush, the protruding part continues to move downward, pushes the pressing part of the clamping ring and the movable block to move outward respectively, and moves the pressing part of the clamping ring to the direction close to the female sleeve to compress the first spring and the lower end of the rotating block that rotates outward to compress the second spring;

[0049] When the protruding part moves below the pressing part of the clamping ring and the movable block, the pressing part of the clamping ring and the movable block are reset inward respectively under the action of the first spring and the second spring, so that the lower surface of the pressing part of the clamping ring and the upper surface of the protruding part are lapped to stop the male sleeve.

[0050] When the inserted male and female are separated from each other:

[0051] The pressing part of the clamping ring needs to be pushed to the direction close to the female sleeve, and the lower end of the rotating block needs to be pressed to the direction close to the female sleeve, so that the protruding part of the clamping ring moves outward to exit the area above the protruding part, and the upper end of the rotating block drives the movable block to move outward to exit the area above the protruding part, the male sleeve that loses the stop moves upward under the action of the female spring, so that the male sleeve can be pulled out of the female sleeve, and then the pressing part of the clamping ring and the lower end of the rotating block are released, so that the protruding part of the clamping ring and the rotating block are reset to the innermost end of the stroke under the action of the first spring and the second spring respectively;

[0052] After the male spring and the female spring lose the compression force, the floating block in the male sleeve moves back to the second inner flange under the action of the reset male spring and re-seals the flow channel in the male sleeve through the third sealing ring, and the floating ring in the female sleeve moves back between the upper flange part and the first inner flange under the action of the reset female spring and re-seals the flow channel in the female sleeve through the first sealing ring and the second sealing ring.

[0053] When the liquid cooling type heat dissipation unit is used, on the basis that the liquid supply circuit and the liquid cooling circuit are conducted after the male and female heads are plugged, the flow channels of the liquid supply circuit and the liquid cooling circuit can be sealed after the male and female heads are separated, the mutual plugging and separation between the male and female heads are facilitated, and the male and female heads can be plugged and separated only when the pressing part on the clasp and the rotating block are pressed simultaneously, so that the loosening between the male and female heads caused by unilateral misoperation is effectively avoided, and the safety and stability during use are improved.

[0054] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
