Examples

Referring to fig. 1 to 4, the utility model discloses a water tank structure without residual water level, which comprises a tank body 1 for storing water and a drain valve 2, wherein the bottom surface of the tank body 1 is downwards sunken to form a mounting groove 11, the bottom of the mounting groove 11 is provided with a mounting opening 12, the bottom end of the drain valve 2 is extended with a mounting part which is detachably inserted into the mounting opening 12, the opening and closing of the drain valve 2 are used for controlling the drainage and water stop of the tank body 1, and when the drain valve 2 is in a closed state, the water stop surface height of the drain valve 2 is lower than the inner bottom surface height of the tank body 1.

The drain valve 2 includes valve body 21, water sealing member 22 and driving piece 23, and a plurality of holes 24 that permeate water with box 1 bottom parallel and level are seted up to the lower extreme pipe wall of valve body 21, and the installation department is the drain pipe 213 of tube-shape, and the bottom outer wall of drain pipe 213 is provided with screw thread 214, and drain pipe 213 inserts and locates mounting hole 12, and screw thread 214 passes mounting hole 12 and through nut 215 cooperation with drain valve 2 detachable connection in box 1, and drain valve 2's stagnant water face sets up in drain pipe 213's top opening part.

The water sealing piece 22 is arranged in the valve body 21 in a vertically movable manner and is used for sealing the water sealing surface so as to prevent water from flowing out of the drain pipe 213, the water sealing piece 22 is driven by the driving piece 23 to ascend in the valve body 21, and the water permeable hole 24 is communicated with the drain pipe 213, so that the opening state of the drain valve 2 is realized; when the external force of the driving member 23 is removed, the water pressure in the tank 1 drives the water sealing member 22 to descend in the valve body 21 to block the water stop surface, so that the water permeable hole 24 and the water discharge pipe 213 cannot be communicated, and the closing state of the water discharge valve 2 is realized.

The valve tube 21 includes an upper valve tube 211 and a lower valve tube 212, the upper valve tube 211 and the lower valve tube 212 are detachably connected by being engaged with the clamping groove by a buckle, and the water permeable hole 24 is provided on the lower valve tube 211.

The outer wall of the drain pipe 213 and above the screw thread 214 are provided with a limiting ring 216, the limiting ring 216 is clamped outside the upper end opening of the mounting port 111, and a sealing piece 217 is sleeved on the drain pipe 213 and between the limiting ring and the bottom surface of the box body for improving sealing performance. One side of the drain pipe 213 is fixedly connected with a connection pipe 218, and both ends of the connection pipe 218 are respectively communicated with the overflow pipe 3 and the drain pipe 213.

An overflow pipe 3 is fixedly arranged on one side of the drain valve 2 and used for preventing water level in the water tank 1 from overflowing the water tank 1 too high, and a pipe orifice at the bottom end of the overflow pipe 3 is communicated with a drain pipe 213.

In this embodiment, the sealing member 22 adopts an inverted T-shaped structure, and includes a sealing plug 221 at the lower end and an upper connecting rod 222, where the sealing plug 221 is longitudinally slidably disposed in the valve body 21 up and down, and the driving member 23 drives the sealing plug 221 to slide up and down through the connecting rod 222. When the water seal box is used, the full-half row keys 13 on the top end of the box body 1 are pressed to drive the driving piece 23 to operate, and the water seal plug 221 is driven to move upwards through the connecting rod 22, so that the water permeable hole 24 is communicated with the drain pipe 213, and the drain is opened; when the drainage is finished, the pressing force on the full half row key 13 is removed, the driving piece 23 is reset, the water blocking head 221 moves downwards, the water outlet 12 is blocked, the water permeable hole 24 is blocked from being communicated with the drainage pipe 213, and the drainage is stopped. Because the water permeable hole 24 on the drain valve 2 is flush with the bottom of the box body 1, when the drain valve 2 is in a closed state, the water stop surface of the water sealing piece 22 in the drain valve 2 is lower than the bottom surface of the box body 1, so that the water storage space in the box body 1 is effectively improved, and meanwhile, water in the box body 1 can be discharged cleanly during drainage.
