Description

Clean water supply system of unit chair for dental surgery

The present invention relates to a pressure water purifying system of a dental unit chair, and more particularly, to a water supply system of a dental unit chair for purifying water supplied to a dental unit chair and simultaneously supplying purified water to a water purifier. will be.

In general, dental medical equipment is equipped with a unit chair (unit chair) is provided to supply water for washing the mouth of the patient.

In addition, when high-speed rotation of a medical device is required or when pressure needs to be injected, compressed air supplied from an air compressor is used.

For example, contra-angle handpieces used in dentistry use compressed air to rotate polishing burs at high speeds (approximately thousands to tens of thousands of rpm), and three-way syringes. A syringe) sprays compressed air and pressure water to clean the required area.

In addition, the contra-angle handpiece uses a pressure water of the same pressure together with compressed air to cool the frictional heat generated in the polishing burr rotating at a high speed and to remove the abrasive residue.

Such a contra-angle handpiece or a three-way syringe is used to be installed in a dental unit chair that is equipped with various medical devices and can sit or lie down for a person to be treated or treated.

In particular, a dental unit chair is provided with a mouthwash after receiving treatment to supply water for the lip and discharge the lip.

2 is a water supply system for a conventional general dental unit chair, and pre-filtration 101 of the raw water 100 with a pre-filter, etc., and a carbon filter 103 through a pump 102 for generating a predetermined pressure. ) And reverse osmosis filter 104 and the like.

The purified water is stored in the auxiliary tank 106 by a constant amount through the pressure regulator (105).

In order to use the purified water in the drinking fountain 107, it is supplied through the auxiliary filtration 108, and in the unit chair 109, which is a medical device, it is supplied through the heater 110 for heating the purified water to a predetermined temperature. Will receive.

The conventional supply system made of the above is filled with water in the auxiliary tank 106, and then pressurized air is made by supplying compressed water, so the compressor must be operated every time it is used, which consumes much energy, shortens the life of the compressor, and wears down parts. However, there are many damages, and the operational costs are increased because the various filters are frequently replaced.

In addition, the supply of pressure water may be cut off during treatment, and even when purified water is used in a storage tank, air dust may contaminate the water in the storage tank and bacteria may multiply.

The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to purify raw water with AC and ACF filters and various filters, and then UV sterilize the raw water and mix it with fluorine when necessary to the dental unit chair. The present invention provides a supply water purification system for a dental unit chair that supplies water to a water purifier used for supplying or drinking water.

According to one aspect of the present invention, there is provided a water purification system for a water purifier, including: an AC filter 12 and an ACF filter 13 for pretreating raw water connected from a water pipe and removing various chemicals; UF membrane filter 21 having a selective filtration function that removes impurities such as bacteria, viruses, and particulates, but does not filter out beneficial substances such as minerals, but has a pore size of 0.001 to 0.01 micron on the surface of the membrane; A hollow fiber membrane membrane filter 25 having more than 100 billion holes of 0.01 to 0.04 micron size; An illite filter 26 for absorbing and decomposing ions and various pollutants and toxicities; A water tank 40 for storing the purified water; An AC / ACF filter 27 for adsorbing odorous gases such as hydrogen sulfide or ammonia dissolved in air or purified water in the water tank 40; Ultraviolet UV lamp tube 29 for sterilizing microorganisms (bacteria, bacteria, etc.) that may be infected with raw water or groundwater undecided by high quality stainless steel; A mixer (41) for mixing the purified and sterilized purified water with fluorine; It characterized in that it further comprises a fluorine tank 38 for supplying fluorine to the mixer (41).

1 is a water supply system for supplying dental unit chairs according to the present invention,

2 is a supply water purification system of a conventional general dental unit chair.
