They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Please see Figures 1-7 The device shown is a water supply device for oral treatment and its water supply pipeline, including a housing 1, a pure water component 2, a water supply component 3, a water storage component 4, a concentrated water pressure gauge 5, a pure water pressure gauge 6, a U-shaped water pipe 7, and a water supply pipeline 8.
[0032] The water supply pipeline 8 serves as the channel connecting the entire device to the external water source and the dental chair. It includes a municipal water supply pipeline 801, an equipment inlet hose 802, a pure water supply hose 803, a return hose 804, and a dental chair water supply pipeline 805. The municipal water supply pipeline 801 serves as the water source inlet, providing the initial water source for the entire device. It connects to the dental chair water supply pipeline 805, allowing tap water to be directly supplied to the dental chair under certain conditions. Both the equipment inlet hose 802 and the pure water supply hose 803 are connected to the municipal water supply pipeline 801. The equipment inlet hose 802 is positioned above the pure water supply hose 803, and a third valve 806 connects them. When the third valve 806 is closed, municipal tap water can enter the pure water component 2 for treatment through the equipment inlet hose 802; when the third valve 806 is open, tap water can be directly supplied to the dental chair through the pure water supply hose 803. The return water hose 804 is connected to the end of the water supply pipe 805 of the dental chair. The water supply pipe 805 of the dental chair is equipped with multiple water outlet pipes, which can be connected to different dental chairs to ensure a stable water supply.
[0033] The water storage assembly 4 is an important part for storing pure water, including a water storage tank 401, an overflow pipe 402, and a drain pipe 403. The water storage tank 401 is made of high-strength, corrosion-resistant material and is located on one side of the casing 1. One end of the overflow pipe 402 is connected to the interior of the water storage tank 401, and the other end extends to the side of the casing 1 away from the water storage tank 401. When the water level in the water storage tank 401 exceeds a set height, excess water will flow out through the overflow pipe 402, preventing damage to the equipment due to overflowing pure water. The drain pipe 403 is located at the bottom of the casing 1, with one end connected to the interior of the water storage tank 401 and the other end extending to the outside of the casing 1 and connected to an external drain pipe via a corrugated pipe. The drain pipe 403 is equipped with a first valve 404 and a second valve 405. The first valve 404 is open when it is not necessary to empty the water tank 401, and the second valve 405 is closed when it is not necessary to empty the water tank 401. When it is necessary to drain, clean and maintain the water tank 401, opening both the first valve 404 and the second valve 405 can achieve the purpose of draining the water in the water tank 401.
[0034] The pure water component 2 converts municipal tap water into pure water that meets the requirements for dental treatment. It includes a pre-filter 201, a first three-way connector 202, a booster pump 203, two reverse osmosis filters 204, a first four-way connector 205, a second four-way connector 206, and a concentrate regulator 207. The pre-filter 201 is fixed to the casing 1 by bolts or other means, and its inlet is connected to the equipment's inlet hose 802, while its outlet is connected to the first three-way connector 202. It can effectively filter out larger particles of impurities, rust, etc. in the tap water.
[0035] The outlet near the top of the first three-way connector 202 is connected to the inlet of the booster pump 203 via a hose. The booster pump 203 is a high-performance pump that provides stable and suitable pressure for subsequent reverse osmosis filtration. The outlet of the booster pump 203 is connected to the inlet of two reverse osmosis filters 204 via a hose. These two reverse osmosis filters 204 are arranged in parallel. The concentrate outlets of both reverse osmosis filters 204 are connected to two branch pipes at the bottom of the first four-way connector 205 via hoses. One of the two branch pipes at the top of the first four-way connector 205 is connected to the concentrate pressure gauge 5 via a hose for real-time monitoring of concentrate pressure, and the other branch pipe is connected to the concentrate regulating component 207 via a hose. The pure water outlets of the two reverse osmosis filters 204 are connected to the two branch pipes at the lower part of the second four-way connector 206 via hoses. One of the two branch pipes at the upper part of the second four-way connector 206 is connected to the pure water pressure gauge 6 via a hose for monitoring the pure water pressure. The other branch pipe is connected to the inside of the water storage tank 401 via a hose to transport the produced pure water to the water storage tank 401 for storage.
[0036] The concentrate regulating component 207 includes a U-shaped hose 207a, a proportional valve 207b, a connecting hose 207c, and a second solenoid valve 207d. One end of the U-shaped hose 207a is connected to one branch of the first four-way connector 205 via a hose, and the other end is connected to the overflow pipe 402 via a hose. The proportional valve 207b is installed on the body of the U-shaped hose 207a. By precisely controlling the opening of the proportional valve 207b, the discharge flow rate of the concentrate can be accurately adjusted. Both ends of the connecting hose 207c are connected to the bodies of both ends of the U-shaped hose 207a, and the second solenoid valve 207d is installed on the connecting hose 207c. When producing pure water normally, the second solenoid valve 207d is open to facilitate the discharge of concentrate. The second solenoid valve 207d can be opened to allow the concentrate to be quickly discharged through the connecting hose 207c.
[0037] The water supply assembly 3 is responsible for delivering pure water from the storage tank 401 to the dental chair and disinfecting the pipeline when necessary. The water supply assembly 3 includes a water supply pump 301, a pure water outlet pipe 302, an ozone generator 303, a vertical water supply pipe 304 for supplying water to the ozone generator 303, and a suction pipe 305. The water supply pump 301 is located at the bottom of the casing 1 and is a quiet, high-efficiency pump. Its outlet is connected to the pure water outlet pipe 302 and the ozone generator 303 via a tee. The pure water outlet pipe 302 is directly connected to the dental chair's water supply pipe 805 to deliver pure water to the dental chair. The upper end of the vertical water supply pipe 304 is connected to a branch pipe at the lower part of the first tee 202, and the other end is connected to the ozone generator 303 to supply water to the ozone generator 303. One end of the pump pipe 305 is connected to the inlet of the water supply pump 301, and the other end is connected to the drain pipe 403. The connection is located between the first valve 404 and the second valve 405 to facilitate the water supply pump 301 to pump pure water from the storage tank 401 into the pure water outlet pipe 302. The vertical water supply pipe 304 is equipped with a ball valve tee 306 and a ball valve controller 307 for controlling the ball valve tee 306. The ball valve controller 307 can remotely or automatically control the switching of the ball valve tee 306. A first flow sensor 308 is also installed on the lower part of the pipe body of the ball valve tee 306 to monitor the water flow in the vertical water supply pipe 304 in real time. When disinfection of the pipeline is not required, the ball valve controller 307 controls the ball valve tee 306 to close, preventing water in the vertical water supply pipe 304 from flowing into the ozone generator 303, and thus preventing it from entering the water supply pump 301. When disinfection of the dental chair water supply line 805 is required, the water pump 301 stops working, and the ball valve controller 307 controls the three-way ball valve 306 to open. Driven by the municipal tap water pressure, the tap water passes through the pre-filter 201 for preliminary filtration and then enters the ozone generator 303. The water mixed with ozone then enters the dental chair water supply line 805 from the pure water outlet pipe 302 for disinfection. A one-way valve 309 is also installed on the water pump 305, with the outlet of the one-way valve 309 located near the inlet of the water pump 301.
[0038] The ozone generator 303 includes a hollow cylindrical outer shell 303a and a first ozone plate 303b. The first ozone plate 303b is disposed inside the outer shell 303a. The first ozone plate 303b adopts ozone generation technology, which can efficiently generate ozone and inject ozone into the water flowing in through the vertical water supply pipe 304.
[0039] A second ozone sensor 406 is installed at the bottom of the water storage tank 401. This second ozone sensor 406 continuously disinfects the pure water in the tank under normal conditions, maintaining water quality. Furthermore, a liquid level sensor 409 and a UV disinfection lamp 407 are installed at the top of the water storage tank 401. The liquid level sensor 409 monitors the water level in the tank 401 in real time and issues an alarm when the water level falls below a set value. The UV disinfection lamp 407, located at the top of the tank 401, further kills microorganisms in the water through ultraviolet irradiation, ensuring the quality of the pure water.
[0040] Both ends of the U-shaped water pipe 7 extend out of the side of the casing 1. The upper end connects to the return water hose 804, and the lower end connects to the external drain pipe 403. The upper part of the U-shaped water pipe 7 is equipped with a first solenoid valve 9. When the equipment is supplying pure water normally, the first solenoid valve 9 is closed to prevent the pure water in the dental chair water supply pipe 805 from flowing into the overflow pipe 402 under water pressure. When the equipment disinfects the dental chair water supply pipe 805, the first solenoid valve 9 is opened. After disinfecting the dental chair water supply pipe 805, the ozone-containing water enters the U-shaped water pipe 7 through the return water hose 804 and then enters the overflow pipe 402, and finally flows into the external sewage pipe.
[0041] The overflow pipe 402 has a sunken bend 408 on the side near the water storage tank 401. The design of the bend 408 can effectively prevent concentrated water from backflowing into the water storage tank 401 under pressure, thus ensuring the quality of the pure water in the water storage tank 401.
[0042] Working principle:
[0043] Pure water production principle: Ball valve controller 307 controls the ball valve tee 306 to close. Municipal tap water enters the pre-filter 201 through the municipal tap water pipe 801 and the equipment inlet hose 802. The pre-filter 201 performs preliminary filtration of the tap water, removing larger particles of impurities. The pre-filtered water enters the first tee 202 and flows through the hose near the upper outlet of the first tee 202 into the inlet of the booster pump 203. The booster pump 203 pressurizes the water and forces it into the two reverse osmosis filters 204. The reverse osmosis filters 204 utilize the characteristics of the reverse osmosis membrane. Under pressure, water molecules pass through the reverse osmosis membrane, while most impurities, bacteria, viruses, heavy metal ions, etc., are trapped on one side of the membrane, thus producing pure water. The pure water produced by the two reverse osmosis filters 204 is collected through hoses to two branch pipes at the lower part of the second four-way connector 206. From there, one branch pipe connects to a pure water pressure gauge 6 via a hose to monitor the pure water pressure, while the other flows into the storage tank 401 for storage. Simultaneously, the concentrated water produced by the two reverse osmosis filters 204 is collected through hoses to two branch pipes at the lower part of the first four-way connector 205. Part of the concentrated water is connected to a concentrated water pressure gauge 5 via a hose to monitor the concentrated water pressure, while the other part is connected to a concentrated water regulating component 207 via a hose, passing through a U-shaped hose 207a and a proportional valve 207b to adjust the concentrated water discharge flow rate, and finally discharged through an overflow pipe 402.
[0044] Disinfection principle of the pipeline: When disinfection is required for the dental chair water supply pipeline 805, firstly, the third valve 806 is kept open, the water supply pump 301 stops working, and the ball valve controller 307 controls the ball valve tee 306 to open. Driven by the municipal tap water pressure, the tap water passes through the pre-filter 201 for preliminary filtration and then enters the ozone generator 303. The water mixed with ozone then enters the dental chair water supply pipeline 805 from the pure water outlet pipe 302, flowing along the dental chair water supply pipeline 805 to disinfect the entire dental chair water supply pipeline 805. The disinfected water enters the U-shaped water pipe 7 through the return water hose 804. The first solenoid valve 9 on the U-shaped water pipe 7 opens, and the disinfected water finally flows into the sewage pipe from the lower port of the U-shaped water pipe 7.
[0045] The principle of the equipment supplying pure water is as follows: When the equipment is normally supplying pure water to the dental chair water supply pipe 805, the ball valve controller 307 controls the ball valve three-way 306 to close, the first valve 404 to open, the second valve 405 to close, the first solenoid valve 9 on the U-shaped water pipe 7 to close, and the water supply pump 301 works to draw pure water from the water storage tank 401 into the drain pipe 403 through the water pumping pipe 305, and then enters the dental chair water supply pipe 805 to achieve the purpose of supplying pure water to the dental chair.
[0046] In summary, this easy-to-remove inner tube vulcanizing equipment, through the coordinated operation of its various components, ensures vulcanization quality and greatly improves production efficiency throughout the entire process from inner tube placement and vulcanization to removal, thus solving many problems existing in traditional inner tube vulcanizing equipment.
