Description

TECHNICAL FIELD

[0001] The utility model belongs to air exhaust valve technical field, concretely relates to a tea maker air exhaust valve. BACKGROUND

[0002] As a convenient tea making device, the tea maker can automatically perform water injection and water boiling after being connected with a water pipe, and the user only needs to manually put tea leaves in the tea barrel to realize automatic tea making. As a common household and commercial appliance, its convenience and efficiency are loved by consumers.

[0003] However, during the water injection stage, when water enters the tea barrel of the tea maker from the water pipe, it will quickly squeeze the original air in the tea barrel. Since the internal space of the tea maker is relatively closed, if the squeezed air cannot be discharged in time, it will hinder the water from entering, resulting in a slow water injection speed, and even possible water flow obstruction and intermittent conditions. During the tea making process, tea leaves and water contact will produce some gas. If the gas cannot be discharged, it will accumulate in the tea maker, hindering the full contact of tea leaves and water, and further affecting the full immersion of tea leaves and the taste of tea soup. Although some tea makers on the market are provided with an exhaust structure, many existing exhaust structures have too many components and complex connection methods in order to realize the exhaust function, which not only increases the manufacturing cost of the tea maker and makes the price of the tea maker relatively high, but also increases the maintenance difficulty of the tea maker. Due to the complex structure, once a fault occurs, the maintenance personnel need to spend a lot of time and effort to troubleshoot and repair the problem. In actual use, the exhaust valve is easily blocked by tea debris, scale and other impurities. Once the exhaust valve is blocked, the automatic exhaust function will fail, and air cannot be discharged. However, most existing tea makers do not have a manual exhaust mechanism. In this case, the user can only wait for the maintenance personnel to come and handle it, or give up using the tea maker. UTILITY MODEL CONTENTS
