Description

Technical Field

[0001] The utility model belongs to the technical field of drainers, and in particular relates to a novel automatic drainer for a tea tray. Background Art

[0002] There is a height difference between the drain outlet of the tea tray and the water bucket. Under normal circumstances, the tea in the tea tray can flow into the water bucket through the drain pipe. However, because the lower end of the drain pipe is immersed in the tea in the water bucket, the tea ferments for a long time, causing air blockage in the drain pipe, resulting in the tea poured on the tea tray being unable to be smoothly discharged into the bucket through the drain pipe.

[0003] A common treatment method is to install a suction ball in the middle of the drain pipe. The suction ball consists of a middle pipe and a hollow ball in the middle of its outer part. When air blockage occurs in the drain pipe, the hollow ball needs to be squeezed to squeeze out the air blockage and the air in the drain pipe is sucked into the hollow ball to form a negative pressure. Under the action of atmospheric pressure, a siphon is formed to discharge the accumulated water in the tea tray through the drain pipe. However, the suction ball is inconvenient to use, so a new automatic drainer for the tea tray is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a novel automatic drainer for a tea tray to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new automatic drainer for a tea tray, comprising an outer tube, an inner tube, an air vent, a channel, a small hole and a cavity, the outer tube being connected to the outside of the inner tube, the air vent being opened in the outer tube, the channel being arranged at the bottom of the inner tube, the channel gradually becoming smaller from bottom to top, the small hole being opened at the top of the channel, and the cavity being arranged between the outer tube and the inner tube.

[0006] As a preferred solution, there are three air outlet holes, the diameter of each air outlet hole is 1 mm, and the three air outlet holes are distributed in a circular array.

[0007] As a preferred solution, the diameter of the bottom end of the channel is 5 mm, and the diameter of the small hole is 1 mm.

[0008] As a preferred solution, the channel is connected to the cavity through a small hole, and the cavity is connected to three air outlet holes.

[0009] As a preferred solution, the diameter of the inner wall of the outer tube is the same as the diameter of the outer wall of the inner tube.

[0010] As a preferred solution, the cavity is arranged between the small hole and the air outlet, and the small hole is arranged below the air outlet.

[0011] As a preferred solution, two recesses are provided in the outer tube, and four convex rings are connected to the outside of the outer tube, and the four convex rings are respectively arranged above and below the cavity.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with a channel, a small hole, an air outlet hole, a cavity and an inner tube. Since the inner tube can be connected with the three air outlet holes through the channel, the small hole and the cavity, the air pressure in the inner tube is consistent with the atmospheric pressure of the external pressure. When the water in the tea tray is discharged through the water outlet, the gas inside the inner tube and the water inlet pipe above it can be discharged from the three water outlet holes through the channel, the small hole and the cavity, so that the water flowing out from the water outlet of the tea tray can smoothly flow into the inner tube through the water inlet pipe, and then the water in the inner tube and the water inlet pipe above it can press the gas in the water pipe inserted in the water bucket into the water bucket under the action of its own gravity, so that the water flowing into the inner tube can smoothly flow into the external water bucket through the drain pipe. The drainer does not need to be squeezed during use, and the water in the tea tray can automatically flow into the external water bucket through the drainer, which is convenient to use.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] See also Figure 1-4The utility model provides a new automatic drainer for a tea tray, comprising an outer tube 1, an inner tube 3, an air outlet 2, a channel 4, a small hole 5 and a cavity 7. The outer tube 1 is connected to the outside of the inner tube 3, and the diameter of the inner wall of the outer tube 1 is the same as the diameter of the outer wall of the inner tube 3. By arranging the outer tube 1 and the inner tube 3, since the diameter of the inner wall of the outer tube 1 is the same as the diameter of the outer wall of the inner tube 3, the gap between the outer tube 1 and the inner tube 3 can form a sealed cavity 7;

[0022] The air outlet hole 2 is provided in the outer tube 1, the number of the air outlet holes 2 is set to three, the diameter of the air outlet hole 2 is 1 mm, and the three air outlet holes 2 are distributed in a circular array. The channel 4 is provided at the bottom of the inner tube 3, and the channel 4 gradually becomes smaller from bottom to top. The small hole 5 is provided at the top of the channel 4, and the diameter of the bottom of the channel 4 is 5 mm, and the diameter of the small hole 5 is 1 mm. The cavity 7 is provided between the outer tube 1 and the inner tube 3, and the channel 4 is connected to the cavity 7 through the small hole 5. The cavity 7 is connected to the three air outlet holes 2, and the cavity 7 is provided between the small hole 5 and the air outlet holes 2. By providing the channel 4, since the channel 4 gradually becomes smaller from bottom to top, the gas in the inner tube 3 can be smoothly gathered inside the channel 4 from the bottom and then move to the cavity 7 through the small hole 5 at the top thereof;

[0023] The small hole 5 is arranged below the air outlet 2, and two recesses 6 are arranged in the outer tube 1. By providing the recesses 6, after the inner tube 3 is inserted into the outer tube 1, the inner and outer tubes 1 are squeezed by a tool so that the inner and outer tubes 1 simultaneously form the recesses 6, which makes it difficult for the inner and outer tubes 1 to be displaced.

[0024] The outer tube 1 is connected to four convex rings 8, which are respectively arranged above and below the cavity 7. By arranging the convex rings 8, the convex rings 8 can connect the water inlet pipe, the drain pipe and the drainer more firmly.

[0025] The working principle and use process of the utility model: when the drainer needs to be used, the top end of the outer tube 1 is connected to the water outlet of the tea tray through the water inlet pipe, and the bottom end of the outer tube 1 is inserted into the external bucket through the drain pipe and into the water in the bucket;

[0026] Because the inner tube 3 can be connected with the three air outlet holes 2 through the channel 4, the small hole 5 and the cavity 7, the air pressure in the inner tube 3 is consistent with the atmospheric pressure of the external pressure. When the water in the tea tray is discharged through the water outlet, the gas inside the inner tube 3 and the water inlet pipe above it can be discharged from the three water outlet holes through the channel 4, the small hole 5 and the cavity 7. The water flowing out of the water outlet of the tea tray can smoothly flow into the inner tube 3 through the water inlet pipe. Then, the water in the inner tube 3 and the water inlet pipe above it can press the gas in the water pipe inserted into the water bucket into the water bucket under the action of its own gravity, so that the water flowing into the inner tube 3 can smoothly flow into the external water bucket through the drain pipe.
