AI Technical Summary
When replenishing water tanks, the movement of the inner core pipe of the drain valve will affect the valve's inner core pipe, causing the valve to close in advance, affecting the drainage volume.
A concealed water tank is designed, adopting a separate structure between the water replenishment channel and the drainage channel. The water replenishment water flow enters the drainage channel through the water replenishment channel, thereby avoiding direct impact on the movement of the inner core pipe of the drainage valve.
It effectively avoids the impact force of the water replenishing water flow on the inner core pipe of the drain valve, prevents the valve from closing in advance, ensures the stability of the drainage, and replenishes water in the water tank for easy maintenance.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bathrooms, in particular to a concealed water tank. Background Art
[0002] When a concealed water tank is equipped with a siphon toilet, a water replenishment function is required to provide a water replenishment function so that the water seal of the toilet can be restored in time after flushing to seal off the odor in the toilet pipe. In the existing concealed water tank, the water replenishment pipe is connected to the inner core pipe of the drain valve. When the drainage is started, the water in the water replenishment pipe will also replenish the toilet through the inner core pipe of the drain valve. The impact force of the replenishment water flow has different values under different water pressures. The greater the water pressure, the greater the impact force. The inner core pipe of the drain valve will fall prematurely due to the additional impact force, causing the valve to close prematurely, thereby affecting the drainage volume. In addition, the up and down movement of the inner core pipe of the drain valve will affect the change in the direction of the replenishment water flow, thereby affecting the impact force and ultimately affecting the drainage volume. Utility Model Content
[0003] The utility model aims to provide a concealed water tank which can replenish water without affecting the inner core tube and the water discharge amount.

[0006] Furthermore, a water supply joint is provided at the water inlet end of the water supply channel, and the water supply joint is connected to the water supply channel. The upper part of the outer wall of the water supply joint forms a butt joint, and the lower part thereof forms a threaded area. One end of the water supply pipe is inserted into the butt joint. A fixing nut is also screwed on the water supply joint. The upper part of the inner wall of the fixing nut is a fixing part, and the lower part thereof forms a connecting part with a thread, and the connecting part is used to be screwed with the threaded area. When the connecting part is screwed to the threaded area, the fixing part is sleeved around the butt joint and squeezes and fixes the water supply pipe inserted on the butt joint.
[0007] Furthermore, the top of the butt joint is inclined inwardly to form a guide surface.
[0008] Furthermore, a lug is provided on the outer peripheral wall of the fixing nut.
[0009] Furthermore, the water supply pipe is a soft water supply pipe.
[0010] After adopting the above scheme, the beneficial effects of the utility model are:
[0011] In the utility model, the drain valve base is provided with a water replenishment channel, and the water tank is provided with a water replenishment pipe, one end of the water replenishment pipe is connected to the water replenishment port of the water inlet valve, and the other end is connected to the water inlet end of the water replenishment channel, and the water outlet end of the water replenishment channel is located in the drainage channel of the drain valve. When the toilet is replenishing water, the water inlet valve takes water from the water replenishment port into the water replenishment pipe, and the water is transported to the water replenishment channel through the water replenishment pipe, and then enters the drainage channel from the water outlet end of the water replenishment channel, thereby entering the toilet for water sealing. During the entire water replenishment process, the replenishment water flow will not affect the inner core tube of the drain valve, thereby avoiding the situation that the inner core tube of the drain valve is affected by the impact force and falls prematurely, causing the valve to close prematurely, thereby affecting the drainage volume. Moreover, when replenishing water in the water tank, if the parts in the water tank are damaged, they can be repaired only through the panel inspection window. Compared with external water replenishment, which requires breaking the wall, it is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
