[0002] The water inlet connector for the toilet tank is installed in the water inlet hole at the bottom of the toilet tank. A float valve is installed on the top of the water inlet connector. Then, the bottom of the water inlet connector is connected to the water supply pipe in the bathroom to fill the toilet tank with water.

[0003] However, traditional water tank inlet pipe connectors, such as those for toilet tanks, require inserting the pipe into the inlet hole at the bottom of the tank and then sequentially installing multiple components such as the sealing gasket and pressure cap. This process is cumbersome and time-consuming, significantly impacting installation efficiency and making installation inconvenient. Furthermore, traditional connectors have certain deficiencies in sealing, easily leading to leaks over long-term use. This not only affects the normal operation of the water tank but may also damage the surrounding environment, causing unnecessary economic losses and inconvenience. Therefore, there is an urgent need for a convenient water tank inlet pipe connector that can solve the above problems. To this end, we propose a convenient water tank inlet pipe connector.

[0022] Please see Figure 1-4A convenient water tank inlet pipe connector includes a water tank and a connector body 1. The bottom of the water tank has an inlet hole 2, and the connector body 1 is disposed inside the inlet hole 2. The connector body 1 includes a vertical pipe 101, a first threaded connector 102, a second threaded connector 103, a first sealing component 104, and a second sealing component 105. The vertical pipe 101 is movably snapped into the inside of the inlet hole 2. The bottom of the vertical pipe 101 passes through the inlet hole 2 and extends to the outside of the inlet hole 2 and is fixedly connected to the first threaded connector 102. The first threaded connector 102 adopts a standard thread design and can be quickly threaded to common external water supply pipes on the market without the need for additional complicated fittings or tools, which greatly simplifies the bottom connection steps and effectively shortens the installation time. The first threaded connector 102 is used to connect to the external water supply pipe. The top of the vertical pipe 101 is fixedly connected to the second threaded connector 103. The surface of the vertical pipe 101 is provided with the first sealing component 104, and the surface of the second threaded connector 103 is fitted with the second sealing component 105.

[0023] Specifically, the first sealing assembly 104 includes a limiting retaining ring 1041 and a first rubber sealing ring 1042. The limiting retaining ring 1041 is fixedly sleeved on the surface of the vertical pipe 101, with the top of the limiting retaining ring 1041 abutting against the bottom of the water tank. The first rubber sealing ring 1042 is also fixedly sleeved on the surface of the vertical pipe 101. The first rubber sealing ring 1042 is made of highly elastic and aging-resistant rubber material, and its outer surface is tightly fitted with the inner wall of the water inlet hole 2, forming the first sealing barrier and effectively preventing water from leaking through the gap between the vertical pipe 101 and the water inlet hole 2.

[0024] In practice, the surface of the first rubber sealing ring 1042 abuts against the inner wall of the water inlet 2, and the bottom of the first rubber sealing ring 1042 is fixedly connected to the top of the limiting ring 1041.

[0025] Specifically, the second sealing assembly 105 includes a limiting sleeve 1051, a sealing gasket 1052, and a second rubber sealing ring 1053, and the limiting sleeve 1051 is connected to the surface thread of the second threaded joint 103.

[0026] In practical implementation, a sealing washer 1052 is fixedly connected to the bottom of the limiting sleeve 1051, and the bottom of the sealing washer 1052 abuts against the bottom of the inner wall of the water tank. The sealing washer 1052 is made of a soft material with excellent sealing performance. When the limiting sleeve 1051 is tightened onto the second threaded connector 103, the sealing washer 1052 is pressed against the bottom of the inner wall of the water tank, tightly abutting against the second threaded connector 103, forming a physical sealing barrier.

[0027] Specifically, the sealing gasket 1052 is movably sleeved on the surface of the second threaded joint 103, the bottom of the sealing gasket 1052 abuts against the top of the vertical pipe 101, and the sealing gasket 1052 abuts against the second threaded joint 103, and the second rubber sealing ring 1053 is fixedly sleeved on the surface of the limiting sleeve 1051.

[0028] In practical implementation, the bottom of the second rubber sealing ring 1053 abuts against the bottom of the inner wall of the water tank, and the second rubber sealing ring 1053 is fixedly connected to the sealing gasket 1052. The second rubber sealing ring 1053 and the sealing gasket 1052 together form a second sealing line, effectively preventing water leakage from the connection between the second threaded joint 103 and the water tank.

[0029] Working Principle: When installing the convenient water inlet pipe connector for this water tank, first align the vertical pipe 101 of the connector body 1 with the water inlet hole 2 at the bottom of the water tank, and movably insert the vertical pipe 101 into the water inlet hole 2. At this time, the limiting retaining ring 1041 abuts against the bottom of the water tank, acting as a limit. Then, connect the external water supply pipe to the first threaded connector 102 via a threaded connection to complete the bottom connection. Next, thread the limiting sleeve 1051 onto the surface of the second threaded connector 103. As the limiting sleeve 1051 is tightened, the sealing gasket 1052 is pressed against the bottom of the inner wall of the water tank, and at the same time, the second rubber sealing ring 1053 is also tightly fitted against the bottom of the inner wall of the water tank, completing the top sealing connection. In this way, the installation of the convenient water inlet pipe connector for the water tank is completed quickly and firmly, and the double sealing structure ensures good sealing performance. During use, when an external water supply pipe supplies water to the water tank, the presence of the first sealing component 104 and the second sealing component 105 can effectively prevent water from leaking from the connection between the joint and the water tank, ensuring that the water tank can store and supply water normally and stably.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
