Description

Technical Field

[0001] The utility model belongs to the technical field of drainage valves, in particular to a flushing tank drainage valve which is splash-proof. Background Art

[0002] In current water tanks, the inlet and outlet are controlled by the inlet valve and the drain valve respectively. Generally, the opening and closing of the drain valve is achieved by operating the switch, while the opening and closing of the inlet valve is controlled by the float. When the drain valve is opened and the water level drops to a certain position, the float will automatically fall, allowing the inlet valve to open and water to enter the water tank.

[0003] The large floating rods with heavy center holes on flush tank drain valves currently on the market are all straight, with a water passage formed in the middle of the sleeve. When the sleeve is pulled up, the passage in the middle of the sleeve forms a communicating vessel with the water tank. When draining water, due to the water level difference, excessive water pressure will cause water to splash out from the top of the large floating rod, resulting in a bad user experience. Utility Model Content

[0004] The technical problems to be solved by the utility model are:

[0005] When draining, water will gush out from the upper opening of the casing, and splash around after reaching the top of the casing.

[0006] In order to solve the above technical problems, the technical solution proposed by the utility model is: a splash-proof flush tank drain valve, including a main body, a base, a large float rod and a small row assembly, the base is fixedly sleeved on the outside of the main body, the large float rod is movably arranged in the main body, the small row assembly is movably arranged on the large float rod, a water sealing ring is clamped at the bottom of the large float rod, a large float rod fixing seat is fixedly installed on the top of the main body, the large float rod passes through the large float rod fixing seat, the small row assembly is arranged above the large float rod fixing seat, and a base water sealing ring is provided in the groove at the bottom of the base.

[0007] Furthermore, a drainage hole is provided on the base, and one end of the water sealing ring is clamped on the bottom of the large floating rod and the other end is placed on the drainage hole.

[0008] Furthermore, the water sealing ring is arranged in a tubular shape, with a pillar on the top, a baffle on the pillar, an O-ring groove on the water sealing ring, a water inlet pipe O-ring mounted on the O-ring groove, the bottom of the water sealing ring extends outward, a water sealing rubber ring groove is provided on the outer float, a water sealing rubber ring is mounted on the water sealing rubber ring groove, and a water outlet is formed between the baffle and the water sealing ring.

[0009] Furthermore, a bayonet is provided at the bottom of the large floating rod, and the water sealing ring is clamped on the bayonet.

[0010] Furthermore, the water sealing ring is made of plastic material, and the base water sealing ring, water sealing rubber ring and water inlet pipe O-ring are all made of rubber material.

[0011] Furthermore, a limiting ring for limiting the position of the small row assembly is provided on the large float rod, and the small row assembly includes a gravity cup, a half-row pull rod and a shift lever. The gravity cup is sleeved on the outside of the large float rod, the half-row pull rod is arranged on the upper side of the gravity cup, and the shift lever is arranged on the lower side of the gravity cup. The shift lever passes through the large float rod fixing seat and the bottom is limited by the large float rod fixing seat.

[0012] Furthermore, the gravity cup is provided with a slot and a sliding adjusting plate, and the adjusting plate and the slot form an adjustable drainage slot.

[0013] Furthermore, a full row of tie rods are provided on the upper side of the large floating rod.

[0014] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] The baffle plate set on the top of the water sealing ring can prevent the water from flowing back upward when the water flow is insufficient, so that the water will not splash out of the box from the upper end of the large float rod, which provides a better user experience. At the same time, it reduces the number of mold development sets and plastic parts, thereby reducing the mold development costs and the cost of plastic materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 As shown, the utility model proposes a splash-proof flush tank drain valve, including a valve body and a valve seat. The valve body is composed of a main body 1, a large float rod 3, a large float rod fixing seat 6, a full-row pull rod 9, a half-row pull rod 11, a gravity cup 10, an adjusting plate 13, a shift lever 12, a water sealing ring 5, a water inlet pipe O-ring 20, and a water sealing rubber ring 18. The valve seat is composed of a base 2 and a base water sealing ring 7. The large float rod 3 and the large float rod fixing seat 6 are installed in the main body 1. The adjusting plate 13 is installed on the gravity cup 10 to adjust the drainage water volume. The shift lever The rod 12 is installed on the gravity cup 10, the gravity cup 10 is installed on the large float rod 3, the large float rod 3 is installed with a full row of pull rods 9, the gravity cup 10 is installed with a half row of pull rods 11, the large float rod 3 is a middle-through pipe structure, and a card hole is provided at the bottom pipe opening. The water sealing ring 5 is installed at the bottom pipe opening of the large float rod 3 by a card buckle method, the water inlet pipe O-ring 20 is installed in the O-ring groove 21 at the upper end of the water sealing ring 5, the water sealing rubber ring 18 is installed in the water sealing rubber ring groove 22 at the lower end of the water sealing ring 5, the base 2 is provided with a drainage hole 8, and a base water sealing ring 7 is installed.

[0025] The water sealing ring 5 is tubular, and a plurality of pillars 16 are provided at the water outlet on the upper end of the water sealing ring 5, and a baffle 17 is provided on the pillar 16.
