The central drain hole of the artificial stone drain outlet 3 is rounded, so that it is convenient to clean the pool and the artificial stone drain outlet 3. When installing, it is only necessary to use the direct joint 2 to connect the deodorizing drain pipe 1 and the artificial stone drain outlet 3, which is simple and quick. The central drain hole of the artificial stone drain outlet 3 is blocked by the freely removable artificial stone drain cover 4, which is also convenient when cleaning the artificial stone drain cover 4. A water discharge component 5 is provided to automatically lift the artificial stone drain cover 4, that is, when there is a lot of sewage in the pool, there is no need for people to reach into the sewage to remove the artificial stone drain cover 4, so as to avoid the sewage soaking clothes or causing damage to the human body;

[0021] The water discharge component 5 includes a sealing tube 501 and a receiving groove 502. The sealing tube 501 is fixedly installed on the inner wall of the artificial stone drain port 3. The top of the sealing tube 501 extends into the receiving groove 502. The receiving groove 502 is arranged at the bottom of the artificial stone drain cover 4. A piston 504 is slidably arranged on the inner wall of the sealing tube 501. A lifting rod 503 is fixedly installed on the top of the piston 504. The top of the lifting rod 503 extends into the receiving groove 502. The end of the sealing tube 501 away from the receiving groove 502 is connected to an air source component 505. The air source component 505 is used to supply air to the sealing tube 501. High-pressure airflow is introduced into the sealing tube 501, so that the airflow pushes up the piston 504, and then pushes up the lifting rod 503, and the lifting rod 503 pushes up the artificial stone water cover 4, so that a gap appears between the artificial stone water cover 4 and the central water hole of the artificial stone water outlet 3. At this time, sewage can flow directly into the odor-proof water pipe 1. When it is necessary to block the water hole, it is only necessary to extract the airflow in the sealing tube 501 through the air source component 505. Under the action of the pressure difference, the piston 504 moves downward to drive the lifting rod 503 to move downward, so that the artificial stone water cover 4 is reset to block the water hole;

[0022] The air source assembly 505 includes a clamp joint 5051 and a circulation pump 5054. The output end of the circulation pump 5054 is connected with an air inlet pipe 5053. The air inlet pipe 5053 is connected with a tee pipe 5052 at one end facing the sealing pipe 501. The tee pipe 5052 is connected with the sealing pipe 501 through the clamp joint 5051. The sealing pipe 501 and the lifting rod 503 are connected through the clamp joint 5051. That is, after the artificial stone drain 3 and the artificial stone drain cover 4 are installed, the air source assembly 505 is connected with the sealing pipe 501 to prevent the air source assembly 505 from interfering with the installation of the artificial stone drain 3 and the artificial stone drain cover 4. The circulation pump 5054 is connected with the sealing pipe 501 through the tee pipe 5052 and the air inlet pipe 5053. The high-pressure airflow is introduced into the sealing pipe 501 through the circulation pump 5054 and the air in the sealing pipe 501 is extracted.

[0023] The interior of the deodorizing drain pipe 1 is provided with an anti-backflow plate 6 to prevent sewage backflow, and the outer wall of the left end of the deodorizing drain pipe 1 is provided with an anti-slip sleeve, so that it is not easy to slip when connecting the deodorizing drain pipe 1 and the direct connector 2;

[0024] There are three sealing tubes 501 and receiving grooves 502, and the circumferential array is distributed on the artificial stone drain port 3 and the artificial stone drain cover 4. The three-way pipes 5052 in the adjacent air source components 505 are connected through the connecting hose 10. The three sealing tubes 501 and receiving grooves 502 are provided so that force is exerted from three positions when the artificial stone drain cover 4 is lifted, so as to prevent the artificial stone drain cover 4 from tilting during the lifting process.

[0025] The circulation pump 5054 is electrically connected to a switch 8 via an electric wire 7 for manually controlling the switch and start-up mode of the circulation pump 5054. A mounting plate 9 is fixedly mounted on the outer wall of the switch 8 for mounting the switch 8 on the water pool.

[0026] Working principle: When in use, align the artificial stone drain 3 with the opening on the pool, then insert it from top to bottom, connect the direct joint 2 with the bottom end of the artificial stone drain 3, and then connect the deodorizing drain pipe 1 with the direct joint 2, so that the artificial stone drain 3 can be installed. Insert the artificial stone drain cover 4 into the central drain hole of the artificial stone drain 3. When cleaning the pool or the artificial stone drain 3, just remove the artificial stone drain cover 4. When there is a lot of sewage in the pool, turn on the circulation pump 5054 through the switch 8 to pump water into the sealing pipe 5054. 1 is introduced into high-pressure airflow, so that the airflow pushes up the piston 504, and then pushes up the lifting rod 503, and the lifting rod 503 pushes up the artificial stone water cover 4, so that a gap appears between the artificial stone water cover 4 and the central water hole of the artificial stone water outlet 3. At this time, the sewage can directly flow into the odor-proof water pipe 1. When it is necessary to block the water hole, it is only necessary to extract the airflow in the sealing tube 501 through the air source component 505. Under the action of the pressure difference, the piston 504 moves downward and drives the lifting rod 503 to move downward, so that the artificial stone water cover 4 is reset to block the water hole.

[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
