AI Technical Summary
When old-fashioned floor drains lose water or lack of water storage, they will lead to the loss of water sealing, and the odor and toxic gases in the sewer may overflow, and the water sealing can easily dry up, which increases the structural difficulty and civil construction costs, affects the drainage speed and cleaning difficulty.
A floor drain that automatically replenishes water is designed, using a combination of a liquid level sensor and a solenoid valve. When the liquid level sensor detects that the water level is low, it automatically opens the solenoid valve, replenishes the water volume through the water replenishing pipe, ensures the optimal state of the water seal, and filters impurities in the water through the filter ring and the filter metal mesh.
The automatic replenishment and deodorization effect of floor drain water seal is achieved, which avoids the odor overflow problem caused by shallow water seal, improves the use stability and drainage efficiency of floor drains, and reduces structural difficulty and civil construction costs.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor drains, in particular to an automatic water-replenishing floor drain. Background Art
[0002] The floor drain is an important interface between the drainage system and the indoor floor in a house. The quality of the floor drain directly affects the indoor air quality, because the sewer pipes and septic tanks of the floor drain are connected to the living space. The old-fashioned floor drain relies on water storage to form a water seal to separate the living space from the pipe system. If the floor drain loses water or does not store enough water, the water seal function will be lost, and the sewer will not be separated from the indoor space. The odor and toxic and harmful gases in the sewer will overflow along the pipe and spread in the room. Most old-fashioned water-sealed floor drains have shallow water seals and less water seals. They will dry up and return to odor due to time and dry weather. If the water seal height is deepened, the floor thickness will be increased, the structural difficulty will be increased, the civil engineering cost will be increased, and the drainage speed will be affected. The deposited dirt will be aggravated and difficult to clean.
[0003] The patent application number CN202111376596.1 discloses an automatic water-replenishing intelligent deodorizing floor drain device, including a ball-type automatic water-replenishing deodorizing floor drain device and a spring-type automatic water-replenishing deodorizing floor drain device.
