AI Technical Summary
When the air conditioner drain interface is directly connected to the drain pipe, condensate water is prone to dripping during maintenance and disassembly, causing pollution in the passageway or corridor.
Design a drain valve that uses a first elastic body to push the valve core to close the outlet, opens when the drain pipe is inserted and closes when it is separated, and achieves a stable connection by combining a snap-fit component and a sliding sleeve structure.
It avoids direct drainage when no drain pipe is installed, prevents condensate dripping, and facilitates water-stopping operations during maintenance.

Abstract
Claims
1. A drain valve characterized by, include: The valve body has a first inlet and an outlet that communicate with the valve chamber; The valve core is movably disposed inside the valve cavity; A first elastic body is disposed inside the valve cavity, and the first elastic body pushes the valve core closer to the outlet to close the outlet. When the drain pipe is inserted into the valve body from the outlet, the drain pipe pushes the valve core away from the outlet to open the outlet, and the outlet is connected to the second inlet of the drain pipe. A connection structure is provided on the valve body and is used to connect the drain pipe.
2. The drain valve of claim 1, wherein: The valve core has a first mounting part and a second mounting part, and a first mounting step is provided inside the valve cavity or at the connection position between the valve cavity and the outlet. The first elastomer pushes the second mounting part into the outlet, and the first mounting part abuts against the first mounting step to close the outlet.
3. The drain valve of claim 2, wherein: When the drain pipe is inserted into the valve body from the outlet, the drain pipe pushes the valve core away from the outlet to open the outlet, and the outlet is connected to the second inlet of the drain pipe; The outer wall of the first mounting part has a first gap with the inner wall of the valve cavity, the outer wall of the second mounting part has a second gap with the inner wall of the valve cavity, and the outer wall of the second mounting part has a third gap with the inner wall of the drain pipe. The first gap, the second gap, and the third gap are interconnected.
4. The drain valve of claim 2, wherein: The first mounting portion includes at least two outwardly protruding first protrusions, and a first recess is formed between two adjacent first protrusions; The second mounting portion includes at least two outwardly protruding second protrusions, and a second recess is formed between two adjacent second protrusions.
5. The drain valve of claim 1, wherein: The valve body has a valve cavity with a second mounting step, the valve core has a third mounting portion, the first end of the first elastic body cooperates with the second mounting step, and the second end of the first elastic body cooperates with the third mounting portion.
6. The drain valve of claim 1, wherein: The connection structure includes a snap-fit component and a second elastic body. The snap-fit component is spherical. The valve body is provided with a mounting hole. The snap-fit component is movably disposed inside the mounting hole. The drain pipe is provided with a snap-fit groove for cooperating with the snap-fit component. The snap-fit groove is arc-shaped. The second elastic body is used to push the snap-fit component into the snap-fit groove.
7. The drain valve of claim 6, wherein: The connection structure also includes a sliding sleeve, which is sleeved on the outside of the valve body and slidably connected to the valve body. The inner sidewall of the sliding sleeve is provided with a third protrusion for pushing the snap-fit member inward. There is a mounting cavity between the sliding sleeve and the valve body, and the second elastic body is disposed inside the mounting cavity.
8. The drain valve of claim 7, wherein: The outer side wall of the valve body is provided with a third mounting step, the inner side wall of the sliding sleeve is provided with a fourth mounting step, the first end of the second elastic body cooperates with the third mounting step, and the second end of the second elastic body cooperates with the fourth mounting step.
9. The drain valve according to any one of claims 1-8, characterized in that: The valve body comprises a first connecting body and a second connecting body, the first connecting body is threadedly connected with the second connecting body, and the valve cavity is arranged on the first connecting body and / or the second connecting body. A sealing ring is arranged at a connecting position of the first connecting body and the second connecting body.
10. The drain valve according to any one of claims 1-8, characterized in that: An outer side wall of the valve body is provided with a threaded portion, and a locking nut is externally threadedly connected with the threaded portion.
