The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0030] Embodiment 1: As Figures 1 - 4 , including:

[0031] The bracket 300, and the bracket 300 is fixedly installed inside the dental chair floor box;

[0032] An air treatment assembly includes a first electric ball valve 100. The output end of the first electric ball valve 100 is connected to a first filter 110, and the output end of the first filter 110 is connected to a first pressure regulating mechanism 120;

[0033] A water treatment assembly includes a second electric ball valve 200. The output end of the second electric ball valve 200 is connected to a second filter 210, and the output end of the second filter 210 is connected to a second pressure regulating mechanism 220.

[0034] The specific usage scenario of this embodiment is as follows: The bracket 300 can be selected as an L shape and fixed to the inner wall of the dental chair floor box, providing a stable support structure for the entire device;

[0035] The working process of the air treatment assembly is as follows: When the first electric ball valve 100 is opened, gas enters the system. First, it passes through the first filter 110, which removes impurities in the gas to ensure that the gas meets the usage requirements of the dental chair. Then, the gas reaches the first pressure regulating mechanism 120, which adjusts the air pressure to an appropriate value to meet the requirements of different functions of the dental chair;

[0036] The working process of the water treatment assembly is as follows: After the second electric ball valve 200 is opened, water flows into the system. First, it passes through the second filter 210, which removes impurities in the water. Then, the water flow enters the second pressure regulating mechanism 220, which adjusts the water pressure to an appropriate range to provide stable water pressure for the dental chair. This structural design enables the independent treatment of water and gas, avoiding mutual interference and ensuring the stable operation of the dental chair.

[0037] Embodiment 2: As Figures 1 - 3 , including: a bracket 300, which is fixedly installed in the dental chair floor box; an air treatment assembly, including a first electric ball valve 100, the output end of the first electric ball valve 100 is connected to a first filter 110, and the output end of the first filter 110 is connected to a first pressure regulating mechanism 120; a water treatment assembly, including a second electric ball valve 200, the output end of the second electric ball valve 200 is connected to a second filter 210, and the output end of the second filter 210 is connected to a second pressure regulating mechanism 220. The air treatment assembly and the water treatment assembly are symmetrically distributed left and right. The first electric ball valve 100 and the second electric ball valve 200 have the same structure, the first filter 110 and the second filter 210 have the same internal structure, and the first pressure regulating mechanism 120 and the second pressure regulating mechanism 220 have the same structure.

[0038] The specific usage scenario of this embodiment is as follows: The water treatment component and the air treatment component of the dental chair floor box water and gas filtration and pressure regulation equipment are symmetrically distributed left and right, and the internal structures of the corresponding components are the same. The symmetrical distribution design enables the equipment to achieve standardized production during the production process, reducing the production difficulty. At the same time, due to the same components, it is more convenient and faster to maintain and replace parts of the equipment. When the equipment is running, the symmetrical structure can make the performance of the water and air two-way systems more matched, and the layout is more concise and clear, improving the convenience for operators and debuggers. As a result, during the use of the dental chair, the supply of water and gas is more balanced, improving the overall performance of the dental chair. Through modular assembly, a large number of pipeline structures are saved, making the assembled structure neater and more beautiful, and facilitating the later maintenance of the equipment.

The output end 1 of the first pressure regulating mechanism 120 is fixedly connected to a first pressure gauge 130. The output ends 2 and 3 of the first pressure regulating mechanism 120 are connected to the dental chair air pipe for air flow output. The output end 1 of the second pressure regulating mechanism 220 is fixedly connected to a second pressure gauge 230. The output ends 2 and 3 of the second pressure regulating mechanism 220 are connected to the dental chair water pipe for water flow output. The first pressure regulating mechanism 120 includes a regulating valve seat 1, which is fixedly installed on the outer wall of the top of the bracket 300. A regulating valve core 6 is installed on the inner wall of the regulating valve seat 1. A valve core O-ring 12 is sleeved at the connection between the regulating valve core 6 and the inner wall of the regulating valve seat 1. A valve cap 17 is fixedly installed at the tail of the regulating valve core 6. A sealing gasket is installed in the inner hole of the regulating valve core 6. A stud 15 is fixedly installed on the inner wall of the valve cap 17. A tail spring 18 is sleeved around the stud 15. The head end of the stud 15 is inserted and connected to an air passing column 14. An internal thread gasket 13 is sleeved on the outer wall of the head end of the stud 15. An internal thread 11 is provided on the outside of the internal thread gasket 13. An air and water joint 10 is fixedly installed on the outer wall of the middle of the top of the regulating valve seat 1. A pressure spring sleeve 3 is fixedly installed at the head end of the regulating valve seat 1. An adjusting plate 8 is slidably connected to the inner hole of the regulating valve core 6. An adjusting plate O-ring 9 is sleeved at the connection between the outer wall of the adjusting plate 8 and the inner wall of the regulating valve core 6. A pressure regulating spring 5 is connected to the inner hole of the adjusting plate 8. The pressure regulating spring 5 is located in the inner cavity of the pressure spring sleeve 3. The right end face of the pressure regulating spring 5 contacts a spring gasket 4. The spring gasket 4 is slidably connected to the inner wall of the pressure spring sleeve 3. An adjusting screw 2 is threadedly connected to the inner wall of the pressure spring sleeve 3. The bottom end of the adjusting screw 2 is used to press the adjusting spring gasket 4.

[0040] The specific usage scenario of this embodiment is as follows: The output end 1 of the first pressure regulating mechanism 120 is connected to the first pressure gauge 130, which can accurately display the output air pressure, facilitating the operator to observe and adjust, and ensuring that the output air pressure meets the usage requirements of the dental chair. Similarly, the output end 1 of the second pressure regulating mechanism 220 is connected to the second pressure gauge 230, which can accurately display the output water pressure, ensuring that the water pressure is stable and appropriate. The specific working process of the first pressure regulating mechanism is as follows: First, rotate the adjusting screw 2 to set an initial pressure, and sequentially push the spring gasket 4, pressure regulating spring 5, adjusting plate 8, and air column 14 to move leftward, so that the contact surface between the air column 14 and the internal thread gasket 13 is separated, ensuring the communication between the left and right chambers of the regulating valve core 6. The gas enters from the left end of the regulating valve seat 1, first passes through the left chamber of the valve core 6, and the valve core O-ring 12 plays a sealing role to prevent gas leakage. Then it passes through the air column 14 to the right chamber of the valve core 6, and then discharges from the outlet of the valve seat 1. When the pressure at the outlet of the valve seat 1 gradually increases, the gas entering the right chamber of the valve core 6 will push the adjusting plate 8 to move rightward, and the air column 14 also follows the adjusting plate 8 to move rightward under the thrust of the tail spring 18 until the contact surface between the air column 14 and the internal thread gasket 13 fits, separating the left and right chambers of the valve core 6. At this time, the pressure at the outlet of the valve seat 1 is equal to the set initial pressure value, achieving the purpose of restricting the outlet pressure value. By rotating the adjusting screw 2, the position of the spring gasket 4 can be changed, thereby adjusting the pre-tightening force of the pressure regulating spring 5 on the adjusting plate 8, and finally realizing the adjustment of the output gas pressure; The specific working process of the second pressure regulating mechanism is the same as that of the first pressure regulating mechanism, achieving the precise adjustment of the water pressure.

[0041] The working principle of the present invention is: When in use, those skilled in the art fix the L-shaped bracket 300 inside the dental chair floor box to provide a stable support for the water treatment component and the gas treatment component. The water treatment component and the gas treatment component are symmetrically distributed left and right, and the corresponding component structures are the same, facilitating standardized production, maintenance, and replacement, and also conducive to the performance matching of the water and gas two-way systems;

[0042] Initial treatment of water and gas: Open the first electric ball valve 100, and the gas enters the gas treatment component. First, it passes through the first filter 110 to remove impurities in the gas; Open the second electric ball valve 200, and the water flow enters the water treatment component. After passing through the second filter 210, the impurities in the water are removed to ensure the cleanliness of water and gas;

[0043] Pressure Regulation and Control: The filtered gas and water enter the first pressure regulating mechanism 120 and the second pressure regulating mechanism 220 respectively. Taking the first pressure regulating mechanism 120 as an example, first rotate the adjusting screw 2 to set an initial pressure, and sequentially push the spring gasket 4, the pressure regulating spring 5, the adjusting plate 8, and the gas passing column 14 to move leftward, so that the contact surface between the gas passing column 14 and the internal thread gasket 13 is separated, ensuring the communication between the left and right chambers of the regulating valve core 6. The gas enters from the left end of the valve seat 1, first passes through the left chamber of the valve core 6, and the valve core O-ring 12 plays a sealing role to prevent gas leakage. Then it passes through the gas column 14 to the right chamber of the valve core 6 and is discharged from the outlet of the valve seat 1. When the pressure at the outlet of the valve seat 1 gradually increases, the gas entering the right chamber of the valve core 6 will push the adjusting plate 8 to move rightward, and the gas passing column 14 also follows the adjusting plate 8 to move rightward under the thrust of the tail spring 18 until the contact surface between the gas passing column 14 and the internal thread gasket 13 fits, separating the left and right chambers of the valve core 6. At this time, the pressure at the outlet of the valve seat 1 is equal to the set initial pressure value, achieving the purpose of limiting the outlet pressure value. By rotating the adjusting screw 2, the position of the spring gasket 4 can be changed, thereby adjusting the pre-tightening force of the pressure regulating spring 5 on the adjusting plate 8, and finally realizing the regulation of the output gas pressure. The principle of the second pressure regulating mechanism 220 for regulating the water pressure is the same as that of the first pressure regulating mechanism 120. The first pressure gauge 130 connected to the output end 1 of the first pressure regulating mechanism 120 and the second pressure gauge 230 connected to the output end 1 of the second pressure regulating mechanism 220 can accurately display the water and gas pressures, facilitating the operator to monitor and adjust. The water and gas after pressure regulation respectively cooperate with the dental chair water pipe through the output ends 2 and 3 of the second pressure regulating mechanism 220 and cooperate with the dental chair air pipe through the output ends 2 and 3 of the first pressure regulating mechanism 120, and are stably output to the dental chair, providing qualified water and gas resources for various functions of the dental chair, such as water spraying, air supply drive, and instrument flushing, to ensure the normal operation of the dental chair.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
