AI Technical Summary

Technical Problem

Existing tea tray drainage accessories have problems such as water not draining automatically, not automatically shutting off when full, tea leaves or tea stems blocking the switch causing malfunction, difficulty in observing tea stains inside the water bucket, and dripping water from the hose when submerged in water. They also cannot achieve automatic shut-off when full.

Method used

The design incorporates an air vent valve to control air release from the water tank. The water level controls the air vent valve to reduce or shut off the air release from the tank, preventing water from overflowing. Pressure is released via a pressure relief button. An extension pipe is included to prevent air from being ejected. The water inlet connector avoids air blockage, and the inner connector and sealing ring prevent water from flowing out.

Benefits of technology

It automatically shuts off when the water is full, preventing water from overflowing, avoiding tea leaves from blocking the switch, reducing tea stains buildup in the water tank, preventing dripping and water leakage, and improving the automation and safety of tea tray drainage.

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.
