Odorless floor drain capable of automatically replenishing water

The utility model discloses an odorless floor drain capable of automatically replenishing water. The odorless floor drain comprises a floor drain body, a miniature submersible pump, a control device, a water storage tank and a water pipe, wherein the control device is connected with the miniature submersible pump and controls the miniature submersible pump; the miniature submersible pump is put into a fixing frame at the lower end of the inner wall of the water storage tank, and is connected with the lateral wall of a siphon trap of the floor drain body through a water pipe; a sensor is arranged at the flush position of the lateral wall of the siphon trap and a water seal line; when a water level of the siphon trap is lower than the water seal line, the sensor is used for transmitting a signal to the control device; the control device is used for controlling the miniature submersible pump to lastingly run for a set period of time, and water can be quantitatively added to the floor drain body, so that, on one hand, the lost moisture caused by natural evaporation of the floor drain body can be replenished, enough water is stored in the siphon trap of the floor drain body for a long period of time, and the water sealing role of the floor drain body can be kept, so as to reach the long-term odorless effect; and on the other hand, water can be quantitatively added to the floor drain body at regular periods, the water in the floor drain body can be kept fresh and incorruptible, and the odorless effect is further reached.
