Quick disconnecting coupler assembly、female connector and water control valve core

Abstract

A quick-connector assembly, a female connector, and a water control valve core are disclosed. The water control valve core includes a sleeve, a through channel, and at least one drain channel. The sleeve has a first end and a second end opposite to each other. The through channel extends axially along the long axis of the sleeve and connects the first end and the second end of the sleeve. The drain channel is recessed on the outer surface of the sleeve. One end of the drain channel is connected to the second end of the sleeve, and the other end is located between the first end and the second end of the sleeve.

Claims

1. A water control valve core, comprising: A cylindrical sleeve having a first end and a second end opposite to each other; a through channel axially extending through the sleeve along the long axis of the sleeve and connecting the first end and the second end of the sleeve respectively; and at least one drain channel recessed on the outer surface of the sleeve, wherein one end of the drain channel is connected to the second end of the sleeve, and the other end is located between the first end and the second end of the sleeve.

2. The water control valve core as described in claim 1, wherein the sleeve comprises: a cylinder; and a female valve plug coaxially connected to the cylinder, wherein the outer diameter of the female valve plug is smaller than the outer diameter of the cylinder, the through channel passes through both the cylinder and the female valve plug, and the drain channel is recessed on the outer circumferential surface of the cylinder and is respectively connected to two opposite ends of the cylinder.

3. The water control valve core as described in claim 2, wherein the female valve plug is annular and completely surrounds the through passage.

4. The water control valve core as described in claim 2, wherein the through channel is located in the inner diameter of the female valve plug and the cylinder, respectively.

5. The water control valve core as described in claim 1, wherein the drain channel is one of a straight line, an oblique line, an arc, or a spiral.

6. The water control valve core as claimed in claim 1, wherein the drain channel comprises a plurality of drain channels arranged equidistantly on the outer surface of the sleeve.

7. A female connector, comprising: A female head housing having a first front opening, a first rear opening, and a first flow channel, the first front opening and the first rear opening being configured opposite to each other, and the first flow channel being connected to the first front opening and the first rear opening respectively; a fixed shaft being coaxially located within the first flow channel; a water control valve core as described in claim 2, wherein the sleeve of the water control valve core is located within the first flow channel and slidably fitted onto the fixed shaft, such that the through channel accommodates the fixed shaft, the drain channel is covered by the inner wall of one of the flow channels of the first flow channel and communicates with the first flow channel; and a first spring being located within the first flow channel and connected to the sleeve and the fixed shaft respectively.

8. The female connector as described in claim 7, wherein the fixed shaft includes a column, a head and a base, the column being located within the first flow channel and connecting the head and the base respectively, the base being fixed within the first flow channel, and the head being located within the through channel of the water control valve core, wherein the first spring surrounds the column and abuts against the sleeve and the base respectively.

9. The female connector as claimed in claim 7, wherein the female connector housing further comprises: an annular flange that partially protrudes from the inner wall of the flow channel and surrounds the first flow channel, and a portion of the annular flange overlaps with the female valve plug; an annular groove located on the annular flange; and a retaining ring located within the annular groove, wherein the female valve plug is removably located within the retaining ring.

10. A quick connector assembly, comprising: The female connector as described in claim 7; The device includes a male connector housing, a male valve plug, and a second spring. The male connector housing has a second flow channel, a front end portion, a second front opening, a second rear opening, and a stop portion. The second front opening and the second rear opening are arranged opposite to each other. The second flow channel connects the second front opening and the second rear opening respectively. The second front opening is located at the front end portion, and the stop portion is located within the second flow channel. The male valve plug is removably closed into the second front opening. The second spring is located within the second flow channel and connects the male valve plug and the stop portion respectively. When the male connector is mated with the female connector, the front end portion is located within the first flow channel and abuts against the female valve plug. A first annular gap exists between the inner wall of the first flow channel and the front end portion. A second annular gap exists between the inner wall of the first flow channel and the female valve plug. The second annular gap connects the first annular gap and the drain channel respectively.

11. The quick connector assembly as claimed in claim 10, wherein a third annular gap is provided between the inner wall of the first flow channel and the outer peripheral surface of the cylinder, and the distance between the bottom of the drain channel and the inner wall of the first flow channel is greater than the size of the third annular gap.

12. The quick connector assembly as claimed in claim 10, wherein the distance between the bottom of the drain channel and the inner wall of the first flow channel is not greater than the size of the first annular gap and the size of the second annular gap.
