Water tank water inlet valve of float bucket integrated structure

Abstract

The invention provides a water tank water inlet valve of a float bucket integrated structure. The water tank water inlet valve is composed of a water inlet valve body and a float bucket working device. The float bucket working device comprises an outer float bucket and an inner float bucket, wherein the inner float bucket is of an integral structure, and an inner float bucket body and a swing rod are integrally connected to form the inner float bucket. Positioning lugs are arranged on the two sides of the upper end of the swing rod and connected with a water inlet upper end and serve as supporting points so that upward and downward swinging can be achieved. A rubber mat is arranged at the tail end of the swing rod, and the rubber mat can cover or uncover an air opening through swinging of the swing rod so that the water inlet function and the water stopping function can be achieved. A clamping groove is formed in an annular sleeve of the outer float bucket and connected with a protruding block of a water inlet bucket body in a clamped mode. By means of the water tank water inlet valve, the whole water inlet valve body can be detached, and all parts are cleaned, replaced and maintained. After the water inlet valve body is assembled back, no errors or changes occur at the safety water level of the water inlet valve body, consistency of the safety water level can be ensured, and therefore the safety distance required by the siphon resistance function is ensured. The fault rate of products is lowered. The water tank water inlet valve is easy and convenient to assemble, and production cost is reduced.

Description

technical field [0001] The invention relates to a water inlet valve matched with a toilet water tank, in particular to a water tank water inlet valve with an integrated structure of a floating bucket. Background technique [0002] In the existing water tank accessory products, most of the water inlet valves installed in the water tank adopt needle valve type hydraulic pressure difference and lever principle to realize water inlet and water stop. Moreover, the parts of the existing water inlet valve are relatively scattered and cannot be formed as an independent integral part; figure 1 Shown: the outer floating bucket 6 of the floating bucket working device of the water inlet valve is set in the main body of the water inlet valve, which is not easy to remove, and the control device for water inlet and water stop of the water inlet valve is generally lifted by the inner floating bucket 5, Rod 3, movable sleeve 4, rocking rod 2, and rocking rod bolt 9 are composed of five part...

Problems solved by technology

Moreover, the parts of the existing water inlet valve are relatively scattered and cannot be formed as an independent integral part; figure 1 Shown: the outer floating bucket 6 of the floating bucket working device of the water inlet valve is set in the main body of the water inlet valve, which is not easy to remove, and the control device for water inlet and water stop of the water inlet valve is generally lifted by the inner floating bucket 5, Rod 3, movable sleeve 4, rocking rod 2, and rocking rod bolt 9 are composed of five parts; when water enters, the water enters through the water inlet valve, and the water level rises gradually. The floating bucket rises with the water level, and the rising of the inner floating bucket drives the lifting rod to rise. The inner floating bucket and the lifting rod are connected by threads. After the connection, the height of the inner floating bucket can be adjusted, and then the lifting rod is connected with the movable sleeve. The movable sleeve is connected with the rocking rod, and the rocking rod is connected through the rocking rod bolt and used as the fulcrum of the rocking rod. A rubber grain is installed at the end of the rocking rod, and the rubber grain is used as a stress point, and the seal is sealed after passing the force. Live in the air port at the upper end of the water, thus achieving water stop

The disadvantages of the above existing water inlet valves are as follows: (1). The working device of the floating bucket cannot be disassembled as a whole, and it is complicated to clean or replace parts, and its safe water level is easy to change after being assembled; (2). The control device of the water-stopping process is completed by sharing 5 parts, resulting in time-consuming, labor-intensive and material-consuming; (3). Adjusted to the height of the floating bucket, if the height of the floating bucket is adjusted, its working water level WL will change, which will cause the distance from the working water level WL to the critical water level CL to change, and the consistency of the product safety water level cannot be guaranteed, so that the product’s The distance required for the anti-siphon function cannot be effectively guaranteed
