Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of toilet water tank water supply, in particular to a toilet telescopic valve. BACKGROUND

[0002] The toilet telescopic valve is a water inlet control device used in the toilet water tank, mainly composed of a valve body, a telescopic rod and a float ball, and its working principle is to drive the float ball to move up and down through the rise and fall of water level, and then control the opening and closing of the telescopic rod to adjust the water inlet amount of the water tank. When the water level drops, the float ball sinks, the telescopic rod opens, and water flows into the water tank; when the water level rises to a set height, the float ball floats, the telescopic rod closes, and the water inlet stops. The design of the telescopic valve aims to realize automatic water level control and ensure that the toilet water tank can replenish an appropriate amount of water after each flushing. Its advantages include simple structure, easy installation, low maintenance cost, and effective prevention of water tank overflow. In addition, the adjustment function of the telescopic valve enables it to meet the use requirements under different water pressure conditions, and it is a common water inlet control device in modern toilets.

[0003] In the prior art, the float of the telescopic valve body on one side of the toilet water tank is usually adjusted in height by buckle positioning. This adjustment method has obvious shortcomings. First, the adjustment accuracy of buckle positioning is low, and users have difficulty in achieving precise control when adjusting the height of the float, which may result in the water level in the water tank not reaching the optimal state, affecting the flushing effect. For example, too low water level will cause insufficient flushing force, while too high water level may cause overflow. Second, the buckle positioning method is prone to loosening or wear during long-term use, further reducing the stability and reliability of the adjustment. Over time, the float may deviate from the preset position due to loosening of the buckle, causing abnormal water inlet of the water tank, which not only affects the normal use of the toilet, but also may increase the waste of water resources. In addition, the adjustment process of buckle positioning is relatively complicated, and users need to try repeatedly to find the appropriate water level, which brings inconvenience to daily maintenance, especially in environments where the water level needs to be adjusted frequently. This adjustment method is inefficient and may cause users to give up adjustment due to complex operation, thereby affecting the overall performance and service life of the toilet. Therefore, the personnel in this technical field provide a toilet telescopic valve to solve the problems raised in the above background. UTILITY MODEL CONTENTS
