Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1, the present invention provides a novel three-way joint, which comprises a first joint 1, a second joint 2 and a third joint 3 connected simultaneously.

The first joint 1, the second joint 2 and the third joint 3 are provided with openings at two ends and are provided with ventilation cavities which are communicated with the first joint 1, the second joint 2 and the third joint 3 simultaneously, wherein the first joint 1 is provided with a first ventilation cavity 11, the second joint is provided with a second ventilation cavity 21, and the third joint is provided with a third ventilation cavity 31.

The first vent cavity 11 of the first joint 1 and the second vent cavity 21 of the second joint 2 form a main cavity (not shown), the third vent cavity 31 of the third joint 3 is perpendicular to the main cavity, and the novel three-way joint further comprises an exhaust structure arranged in the third joint and a check structure arranged in the main cavity.

In this embodiment, the exhaust structure includes an air release cap 41 sleeved outside the third joint 3 and a valve core 42 accommodated in the third vent chamber 31 of the third joint 3, and the valve core 42 abuts against the top of the air release cap 41. Therefore, the valve core 42 can be linked by pressing the air release cap 41, so that air is exhausted, and the hands are effectively prevented from being hurt by the refrigerant during air exhaust due to the blocking effect of the air release cap 41.

In the present embodiment, the check structure includes a spring 51 and a packing 52. One end of the spring 51 is fixed in the second vent chamber 21 of the second joint 2, the other end of the spring 51 is connected and fixed to the gasket 52 and is located in the first vent chamber 11 of the first joint 1, the first vent chamber 11 of the first joint 1 includes a front chamber 111 and a rear chamber 112, the diameter of the front chamber 111 is smaller than the diameter of the rear chamber 112, the first joint 1 forms a step portion (not shown) at the connection of the front chamber 111 and the rear chamber 112, and the gasket 52 includes a gasket 521 for completely shielding the front chamber 111 and a guide block 522 protruding from one side of the gasket 521 close to the front chamber 111 toward the front chamber 111.

When the spring 51 is in a free extension state, the gasket 521 shields the front cavity 111, the guide block 522 protrudes into the front cavity 111, and when the spring 51 is in a retraction state, the gasket 522 is separated from shielding the front cavity 111.

From this, when admitting air, under the impact of air current, the spring is in the state of retracting, drives the gasket and breaks away from the sheltering from to the antechamber, realizes ventilating, and when not admitting air, the impact of no air current, the spring is in the state of freely stretching, and the gasket top is supported the step portion, realizes sheltering from to the antechamber. Thereby effectively preventing the backflow of the refrigerant.

Specifically, the non-return structure further includes a snap spring 53, and one end of the spring 51 is fixed in the second vent chamber 21 of the second connector 2 through the snap spring 53. The arrangement of the clamp spring is not only beneficial to fixing the spring, but also beneficial to ventilation.

More specifically, the non-return structure further comprises a push rod 54, and the spring 51 is connected and fixed to the sealing pad 52 through the push rod 54. The arrangement of the push rod can ensure that the sealing gasket makes straight line deviation in the main cavity, and the sealing effect is prevented from being influenced by the deflection of the sealing gasket due to uneven stress of the sealing gasket caused by air flow impact.

Compared with the prior art, the utility model discloses a refrigerant hinders hand and refrigerant backward flow when novel three way connection effectively avoids exhausting.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
