Description

Technical Field

[0001] The utility model relates to the technical field of angle valves, and particularly relates to a quick-release angle valve for a concealed water tank. Background Art

[0002] In order to improve the aesthetic effect, the water tanks of existing toilet bowls in bathrooms generally adopt concealed water tanks, which are embedded and installed in the wall body, and the water inlet device of the water tank is connected by an angle valve. Chinese patent application number CN202323053080.0 discloses a filtering angle valve provided on a flushing toilet tank cover, including an angle valve body, a valve core assembly, a valve core seat, a snap ring, a filtering main body with one end open, a filtering element and a fastening nut. The angle valve body includes a main body cavity, a water inlet interface and a water outlet interface. The main body cavity is open at both ends, and a 90-degree stop groove is provided at one end. The water inlet interface and the water outlet interface are on a straight line. The valve core assembly includes an operation part, a neck part, a sealing part, a spherical valve core part provided in the middle of the sealing part and a fixing part. The neck part is provided with a stop block and is connected to the operation part. The spherical valve core part is provided with a water guiding hole. The valve core seat is provided with a water outlet hole and a spherical curved core seat provided at the end. The filtering main body includes a water inlet joint, a first water outlet interface, a second water outlet interface and an external thread part. The sealing part is rotationally matched with and sealed to the main body cavity, the snap ring is engaged with the annular clamping groove of the fixing part, and the stop block is matched with the stop groove. The valve core seat is inserted into the main body cavity from the water outlet interface and is matched with the spherical valve core part. The filtering element is arranged in the inner cavity of the filtering main body, and the fastening nut is screwed with the external thread part to hold the filtering element in the transition main body and is detachable. The water inlet joint and the water outlet interface are communicated. The water inlet interface is connected to the flushing toilet tank cover. The inner cavity of the filtering main body includes a kidney-shaped cavity part and a circular cavity part. Axial positioning grooves are provided on a pair of flat walls of the kidney-shaped cavity part. The filtering element includes a horizontal mesh plate part, a longitudinal partition mesh part and a cylindrical sealing part. The width of the longitudinal partition mesh part is smaller than the width of the horizontal mesh plate part. The longitudinal partition mesh part divides the horizontal mesh plate part into a first filtering part and a second filtering part. In this filtering angle valve structure, a filtering space is formed by the cross-shaped horizontal mesh plate part and the longitudinal partition mesh part. The water inlet joint corresponds to the range surrounded by the left side of the horizontal mesh plate part and the upper side of the longitudinal partition mesh part. In this way, when water enters, it is always the left side of the horizontal mesh plate part and the upper side of the longitudinal partition mesh part that perform the filtering operation. After long-term use, serious impurity accumulation will occur in this part, resulting in blockage of the mesh holes, affecting the water inlet efficiency and increasing the cleaning frequency. The right side of the horizontal mesh plate part and the lower side of the longitudinal partition mesh part belong to secondary filtering, and less impurity accumulation occurs, which causes insufficient utilization of the horizontal mesh plate part and the longitudinal partition mesh part and results in waste. Therefore, this application proposes a quick-release angle valve for a concealed water tank to solve the above problems. Content of the Utility Model
