Abstract

A water valve and a drinking device are provided. The water valve includes an upper support, a lower support, a valve spool, a sealing member, a spring and a water outlet. The upper support is provided with a water inlet. The lower support is provided with a water outlet and a vent hole. The valve spool has a first end connected with the upper support and a second end fixedly connected with the lower support, and the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet. When the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.

First claim

What is claimed is:

1. A water valve, used for a drinking device, comprising:
an upper support connected with the drinking device and provided with a water inlet;
a lower support connected with the upper support, movable relative to the upper support, and provided with a water outlet and a vent hole, the vent hole being communicated with the water outlet;
a valve spool having a first end connected with the upper support and a second end fixedly connected with the lower support, in which the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet;
a sealing member fitted over the first end of the valve spool connected with the upper support;
a spring disposed between the upper support and the lower support; and
a water outlet pipe connected with the lower support and communicated with the water outlet,
wherein when the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.

2. The water valve according to claim 1 , wherein a diameter of the water outlet pipe ranges from 6 mm to 15 mm.

3. The water valve according to claim 2 , wherein the diameter of the water outlet pipe is 10 mm.

4. The water valve according to claim 2 , wherein the first end of the valve spool connected with the upper support is provided with an annular groove, and the sealing member is located in the annular groove.

5. The water valve according to claim 4 , wherein the sealing member is configured as a silicone sealing member.

6. The water valve according to claim 4 , wherein the lower support is provided with a snap, the valve spool is provided with a snapping groove configured to be fitted with the snap, and the valve spool is fixedly connected with the lower support through a fit between the snap and the snapping groove.

7. The water valve according to claim 1 , wherein the water outlet pipe comprises:
a first pipe segment connected with the lower support; and
a second pipe segment connected with the first pipe segment and obliquely arranged relative to the first pipe segment.

8. The water valve according to claim 7 , wherein an included angle between the first pipe segment and the second pipe segment ranges from 30° to 60°.

9. The water valve according to claim 8 , wherein the water outlet pipe is configured as an integrated structure formed by injection molding.

10. A drinking device, comprising a water valve, wherein the water valve comprises:
an upper support connected with the drinking device and provided with a water inlet;
a lower support connected with the upper support, movable relative to the upper support, and provided with a water outlet and a vent hole, the vent hole being communicated with the water outlet;
a valve spool having a first end connected with the upper support and a second end fixedly connected with the lower support, in which the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet;
a sealing member fitted over the first end of the valve spool connected with the upper support;
a spring disposed between the upper support and the lower support; and
a water outlet pipe connected with the lower support and communicated with the water outlet,
wherein when the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.

11. The drinking device according to claim 10 , wherein a diameter of the water outlet pipe ranges from 6 mm to 15 mm.

12. The drinking device according to claim 11 , wherein the diameter of the water outlet pipe is 10 mm.

13. The drinking device according to claim 11 , wherein the first end of the valve spool connected with the upper support is provided with an annular groove, and the sealing member is located in the annular groove.

14. The drinking device according to claim 13 , wherein the sealing member is configured as a silicone sealing member.

15. The drinking device according to claim 13 , wherein the lower support is provided with a snap, the valve spool is provided with a snapping groove configured to be fitted with the snap, and the valve spool is fixedly connected with the lower support through a fit between the snap and the snapping groove.

16. The drinking device according to claim 10 , wherein the water outlet pipe comprises:
a first pipe segment connected with the lower support; and
a second pipe segment connected with the first pipe segment and obliquely arranged relative to the first pipe segment.

17. The drinking device according to claim 16 , wherein an included angle between the first pipe segment and the second pipe segment ranges from 30° to 60°.

18. The drinking device according to claim 17 , wherein the water outlet pipe is configured as an integrated structure formed by injection molding.
