The present invention relates to a drug supply device for urinals, and in particular, when a user's access to the urinal is detected by a sensor, an appropriate amount of drugs is automatically supplied for the purpose of removing odor and disinfecting from a urinal to supply washing water by controlling a water supply device. It relates to an improved urinal medicine supply device with a simple structure so that it can be injected.

In general, urinals installed in public toilets have conventionally opened and closed a valve when a user presses a knob so that washing water is supplied to the urinal, but recently, for user convenience, in response to a sensor signal that detects the user's approach, washing water is a urinal. Urinals that are designed to be automatically supplied are mainly supplied.

In the conventional urinal provided with such an automatic water supply device, as schematically shown in FIG. 1, a sensor 2 is mounted on the upper part of the urinal 1, and the valve control device 3 connected to the water supply pipe responds to the signal of the sensor. It is designed to automatically open and close the valve to supply washing water in response.

In such a conventional urinal, when urinating in the urinal, ammonia contained in the urine remains on the inner side of the urinal, resulting in an odor, which causes discomfort in use and hygiene.Therefore, a fragrance for removing odor when supplying washing water Are being supplied together.

As such, as an example of a urinal in which a fragrance is supplied together with washing water, in Korean Utility Model Publication No. 1995-0009700 (announced on November 22, 1995), a double passage is formed in the fragrance reservoir, and A storage room in which the fragrance is placed is formed and connected to the water supply pipe at the end of the distribution pipe, and the distribution pipe is divided into upper and lower passages by a central diaphragm, and the upper passage is communicated to the upper part of the storage chamber through a guide hole, and the lower passage is The fragrance of the urinal supplied to the urinal by communicating with the lower part of the storage room and flowing into the storage room through the upper passage of the distribution pipe, and discharged to the lower passage and the lower water supply pipe through the outer edge in a state in contact with the air freshener. A mixed water supply device is disclosed.

In such a conventional urinal air freshener mixing water supply system, when the valve is opened for a predetermined time by the automatic water supply and the valve is closed while the washing water is supplied, back pressure is generated in the passage and the storage room, so that the washing water remains in the storage room. The provided fragrance is excessively dissolved in the residual washing water, which causes inconvenience to the user due to the excessive fragrance of the fragrance, and when a chemical to remove ammonia from the urinal is mixed with the fragrance, the chemical remains in the storage room. There was a problem that it was excessively melted and corroded parts such as valves, causing frequent breakdowns.
