Tea tray drainage fitting

Abstract

This application provides a tea tray drainage accessory, including: an air vent valve, a lid, or a water bucket. The air vent valve controls the air release from the water bucket. When the water level reaches a control point, it reduces the air release from the water bucket or shuts off the air vent, creating positive pressure inside the bucket to prevent water from the hose from flowing into the bucket. It automatically shuts off when the water is full. A pressure relief button releases the pressure inside the bucket and indicates whether the bucket is full. An extension tube prevents air from being ejected from the tea tray. The water inlet is located on the lid or top of the water bucket to avoid air resistance, automatically draining water from the tea tray into the water bucket. An inner connector has a switch to prevent water from the tea tray from flowing out of the hose. The air vent valve has a through hole with a movable pin inside. A float is located below the movable pin, and a pressure relief button is located above the movable pin. When the water level in the bucket pushes the float upward, the movable pin moves upward in the through hole, reducing the air release from the water bucket or shutting off the air vent. The pressure inside the bucket increases, preventing water from the hose from flowing into the bucket.

Description

Technical Field

[0001] This application relates to the field of tea tray wastewater collection, and more particularly to a tea tray drainage fitting. Background Technology

[0002] Existing tea tray drainage accessories have several drawbacks. First, water in the tea tray doesn't drain automatically; the drain ball must be pressed to drain. Second, the water in the bucket doesn't automatically stop when full. Third, when water is diverted from the tea tray to a wastewater bucket, air resistance forms in the hose when the water level exceeds the hose outlet. Pouring water back into the tea tray prevents automatic drainage. Adding a drain ball to the hose and squeezing it expels the air. While the hose outlet is positioned at the top of the bucket, water poured into the tea tray drains automatically, but if tea leaves clog the tray, squeezing and releasing the drain ball allows air to return through the outlet at the bottom of the hose, rendering the drain ball ineffective and leaving the hose submerged. Finally, the water in the bucket... Without an automatic shut-off function when full, wastewater can easily overflow onto the floor, causing damage. Tea rinsing water contains tea leaves and stems; if a float switch is installed on the hose, and tea leaves or stems are present between the sealing ring and the drain when the water level reaches the control point, the switch will malfunction, causing the leaves or stems to become stuck. This problem remains unsolved, which is why tea buckets with automatic shut-off when full are not yet available on the market. Over time, tea stains adhere to the bucket walls, making it difficult to see if the bucket is full, even in transparent buckets. The hose inside the bucket is constantly submerged in water, causing dripping when poured out. Residual water from the tea tray also leaks from the hose. Summary of the Invention

[0003] This application addresses the problems of existing technologies by incorporating an air vent valve to control the air release from the water bucket. When the water level reaches a control point, the valve reduces air release from the bucket or shuts off the air vent, creating positive pressure inside the bucket to prevent water from continuing to flow into the bucket and thus preventing wastewater from overflowing. The valve automatically shuts off when the bucket is full. The water inlet is located on the lid or top of the bucket to prevent air blockage, and water from the tea tray is automatically drained into the bucket. A pressure relief button releases the pressure inside the bucket, preventing water from spraying out when the hose is removed from the bucket. The pressure relief button also indicates whether the bucket is full. An extension tube prevents air from being forced out of the bucket and spraying out of the tea tray under pressure. The water inlet has an assembly groove and an inner connector for easy separation of the hose from the bucket. A switch on the inner connector prevents water from the tea tray from flowing out of the hose.

[0004] This application provides a tea tray drainage accessory, including: an air vent valve, a lid, or a water bucket. The air vent valve is disposed on the lid or the water bucket. The air vent valve includes a body with a through hole inside. A movable pin is disposed inside the through hole, and a float is connected to the lower part of the movable pin. When the air vent valve is disposed on the lid, the lid is placed on the water bucket with a water inlet. When the air vent valve is disposed on the water bucket, a lid with a water inlet is placed on the lid of the water bucket. The flexible hose of the tea tray is connected to the water inlet. The float moves as the water level rises and drives the movable pin to close or reduce the flow area of ​​the through hole, thereby increasing the air pressure inside the lid or the water bucket and preventing water in the hose from continuing to flow into the bucket.

[0005] Furthermore, the tea tray drainage accessory also includes a water inlet connector, which is located on the lid or the water bucket and is used to connect a flexible hose from the tea tray. The water inlet connector is located on the top of the lid or the water bucket to prevent air blockage, and water in the tea tray will automatically drain into the water bucket.

[0006] Furthermore, the tea tray drainage accessory also includes an extension pipe, which is located below the water inlet connector to prevent air from being ejected from the tea tray under pressure after the air outlet valve is closed.

[0007] Furthermore, the lid has a notch, which allows the air valve and water inlet connector to be lower than the lid surface, making them less prone to damage during transportation; it also reduces the overall height of the water bucket; and when the water pipe is disassembled, water droplets flow into the notch and will not spill onto the ground.

[0008] Furthermore, the water inlet connector includes: an assembly groove, an inner connector, and a sealing ring; the inner connector is disposed within the assembly groove, and the sealing ring is disposed between the assembly groove and the inner connector; the assembly groove and the inner connector facilitate the separation of the pipe from the water bucket; the sealing ring prevents air from escaping from the water bucket.

[0009] This application also provides another drainage accessory for a tea tray, including: an air vent valve and a pressure relief button: the air vent valve has a main body with a through hole inside, a movable pin inside the through hole, a float below the movable pin, and the pressure relief button above the movable pin; the air vent valve controls the air release of the air vent valve using the water level; the air vent valve is installed on a water bucket with a water inlet, and the flexible hose of the tea tray is connected to the water inlet; the float moves as the water level rises, driving the movable pin to close or reduce the flow area of ​​the through hole, thereby increasing the air pressure inside the lid or water bucket, thus preventing water in the hose from continuing to flow into the bucket; the pressure relief button also moves upward, indicating that the bucket is full; pressing the pressure relief button downward can expel the air in the bucket, allowing the remaining water in the tea tray to flow into the bucket, releasing the pressure inside the bucket, and preventing water from spraying out when the hose is removed from the bucket.

[0010] Furthermore, the vent valve also includes a limit switch, which is provided on the main body or the movable pin; the limit switch prevents the movable pin from falling out of the through hole.

[0011] Furthermore, the vent valve also includes a Y-shaped sealing ring, which is disposed on the main body or the movable pin; the Y-shaped sealing ring prevents air inside the barrel from being discharged to the outside.

[0012] Furthermore, the vent valve also includes a vent hole, which is located on the movable pin; the vent hole allows air in the water bucket to be expelled quickly, reducing the gap between the through hole and the movable pin.

[0013] Furthermore, the limiting device includes: a groove and an elastic ring; the groove is provided on the pressure relief button, and the elastic ring is provided on the groove; the groove is used to assemble the elastic ring, and the elastic ring prevents the movable pin from falling out of the through hole and reduces the noise generated when the movable pin hits the through hole.
