Description

Technical Field

[0001] This invention relates to the field of dental disease treatment and prevention, and more particularly to a sand storage tank for dental air polishing equipment. Background Technology

[0002] Current dental air polishing equipment uses compressed gas (usually air) to agitate abrasive powder (primarily composed of sodium bicarbonate, glycine, or erythritol) from a reservoir. This powder is then transported through an air outlet to the air polishing handle. At the handle's outlet, the powder mixes with a liquid medium (usually water) to form solid crystals. These crystals are then impacted by the high-speed airflow, polishing the tooth surface and removing plaque, soft deposits, early tartar, tobacco stains, and tea stains from both above and below the gum line. Current air polishing systems primarily use variable pressure for abrasive output adjustment; that is, the output changes with the pressure of the injected compressed gas, but it cannot directly adjust the output at a constant pressure. Therefore, current air polishing systems suffer from insufficient flexibility in adjusting the output under constant pressure, making them unsuitable for treating complex dental conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a sand storage tank for dental air polishing equipment, which aims to solve the problem of insufficient freedom in adjusting the sand volume in the prior art, resulting in the inability to meet the treatment needs of complex conditions during air polishing.

[0004] To achieve the above objectives, the present invention provides a sand storage tank for a dental air polishing device, comprising an outer shell, a sand cover, an inner tank, a sand inlet pipe, a guide block, a sand outlet pipe, a base, and a valve mounting component. The outer shell is detachably connected to the inner tank and is fitted onto the outer surface of the inner tank. The sand cover is threaded to the outer surface of the outer shell and is located above the outer shell. The top end of the sand inlet pipe is detachably connected to the inner surface of the top end of the inner tank and is located below the sand cover. The inner tank has a sand storage cavity with a frustum-shaped bottom. The sand inlet pipe has a sand inlet cavity, and the sand storage cavity communicates with the sand inlet cavity. The bottom of the guide block is rotatably connected to the sand inlet cavity and is located at the top of the sand inlet pipe. The top end of the guide block... The guide block has an opening on its side, which faces the sand outlet pipe, and the top of the sand cover is located on the sand inlet chamber. One end of the sand outlet pipe is fixedly connected to the through hole and is located inside the through hole. The other end of the sand outlet pipe passes through the base and is located on the side of the valve mounting component. The base is detachably connected to the outer shell and is located at the bottom of the inner tank. The inner tank has a connecting cavity located below the sand storage chamber. The valve mounting component is detachably connected to the base and is located at the center of the base. The top of the valve mounting component fits into the connecting cavity. The sand storage chamber, the connecting cavity, and the valve mounting component are sequentially connected.

[0005] The sand tank for the dental air-blasting cleaning equipment also includes a knob, which is rotatably connected to the sand cover and located on top of the sand cover. The knob is detachably connected to the top of the guide block and located on top of the guide block.

[0006] The sand storage tank for the dental air-blasting cleaning equipment also includes a one-way duckbill valve, which connects the valve mounting and the sand-drawing chamber and is located between the valve mounting and the sand-drawing chamber.

[0007] The sand tank for the dental sandblasting cleaning equipment also includes an air inlet pipe that passes through the valve mounting and is detachably connected to the one-way duckbill valve, and is located at the center of the valve mounting.

[0008] The sand tank for dental air polishing equipment further includes a first sealing ring, a second sealing ring, a third sealing ring, and a fourth sealing ring. The first sealing ring is fitted inside the knob and located at the connection between the knob and the sand cover. The second sealing ring is fitted inside the sand cover and located at the top of the inner tank. The third sealing ring is fitted on the outer surface of the valve mounting and located inside the connecting cavity. The fourth sealing ring is fitted on the outer surface of the guide block and located at the bottom of the sand cover.

[0009] The beneficial effects of this invention are as follows: When the sand tank is installed on the instrument, compressed gas enters the interior of the sand storage chamber through the air inlet pipe. Sand powder is stirred up at the bottom center hole outlet of the sand storage chamber, forming a mixed fluid that enters the sand inlet pipe. At the top opening of the sand inlet chamber, the flow direction is controlled by a flow guiding structure composed of the sand inlet pipe and the flow guide block. This direction is theoretically perpendicular to the center line of the tank. The angle between the plane formed by the straight line and the center line of the sand inlet pipe and the plane formed by the center line of the sand outlet pipe and the center line of the sand inlet pipe can reflect the amount of sand. By adjusting this angle, the amount of sand output can be adjusted, solving the problem of insufficient freedom in sand output adjustment. The mixed fluid finally enters the sandblasting handle from the sand outlet pipe for operation, meeting the treatment needs of complex conditions. Attached Figure Description

[0019] Please see Figures 1 to 5This invention provides a sand storage tank for a dental air polishing device, comprising an outer shell 5, a sand cover 3, an inner tank 6, a sand inlet pipe 4, a guide block 2, a sand outlet pipe 7, a base 8, and a valve mounting component 14. The outer shell 5 is detachably connected to the inner tank 6 and is fitted onto the outer surface of the inner tank 6. The sand cover 3 is threadedly connected to the outer surface of the outer shell 5 and is located above the outer shell 5. The top end of the sand inlet pipe 4 is detachably connected to the inner surface of the top end of the inner tank 6 and is located below the sand cover 3. The inner tank 6 has a sand storage cavity 15 inside, and the bottom end of the sand storage cavity 15 is frustoconical. The sand inlet pipe 4 has a sand inlet cavity 16 inside, and the sand storage cavity 15 communicates with the sand inlet cavity 16. The bottom of the guide block 2 is rotatably connected to the sand inlet cavity 16 and is located at the top of the sand inlet pipe 4. The top end of the guide block 2 penetrates the sand cover 3 and is positioned... At the top of the sand cover 3, the side of the guide block 2 has an opening 17 facing the sand outlet pipe 7. The top of the inner tank 6 has a through hole 18 located on the side of the sand inlet chamber 16. One end of the sand outlet pipe 7 is fixedly connected to the through hole 18 and located inside the through hole 18. The other end of the sand outlet pipe 7 passes through the base 8 and is located on the side of the valve mounting component 14. The base 8 is detachably connected to the outer shell 5 and is located at the bottom of the inner tank 6. The inner tank 6 has a connecting cavity 19 located below the sand storage chamber 15. The valve mounting component 14 is detachably connected to the base 8 and is located at the center of the base 8. The top of the valve mounting component 14 fits into the connecting cavity 19. The sand storage chamber 15, the connecting cavity 19, and the valve mounting component 14 are sequentially connected.

[0020] In this embodiment, when the sand tank is installed on the instrument, compressed gas enters the sand storage chamber 15 through the inlet pipe 20. Sand powder is agitated at the bottom center outlet of the sand storage chamber 15, forming a mixed fluid that enters the sand inlet pipe 4. At the top opening of the sand inlet chamber 16, a flow-guiding structure composed of the sand inlet pipe 4 and the guide block 2 controls the outflow direction. Theoretically, this direction is perpendicular to the tank's centerline. The angle between the plane formed by the straight line and the centerline of the sand inlet pipe 4, and the plane formed by the centerline of the sand outlet pipe 7 and the centerline of the sand inlet pipe 4, reflects the sand volume. Theoretically, this angle can be adjusted from 0° to 180°. Specifically, the angle when the opening 17 faces the sand outlet pipe 7 is defined as 0°, i.e., the angle when the sand tank is at its maximum sand output is 0°. However, considering the safety of the sand tank and the sand output... The stability of the sand tank is well-documented, and experiments have shown that the sand output does not change significantly when the sand tank is adjusted within the range of 180° to 135°. To facilitate quick and easy adjustment of the sand output during actual operation, the actual adjustment range in this embodiment is 0° to 135°. This adjustment is achieved by rotating knob 1. The sand cover 3 has a scale marked with "Max" and "Min". The adjustment range is 135°. Adjusting this angle allows for adjustment of the sand output, solving the problem of insufficient freedom in sand output adjustment. The mixed fluid ultimately enters the sandblasting handle from the sand outlet pipe 7 for operation, meeting the treatment needs of complex conditions. The bottom of the sand storage chamber 15 is frustum-shaped, with an included angle of 57° between the two inclined surfaces of the frustum. This results in a higher accumulation of sand powder at the bottom of the sand storage chamber 15, which is more conducive to reducing sand powder residue and improving sand powder utilization and operational smoothness.

[0021] Furthermore, the sand reservoir for the dental air-blasting cleaning device also includes a knob 1, which is rotatably connected to the sand cover 3 and located on top of the sand cover 3. The knob 1 is detachably connected to the top of the guide block 2 and located on top of the guide block 2.

[0022] In this embodiment, the knob 1 allows the user to more precisely adjust the angle between the opening 17 and the sand outlet pipe 7, enabling the user to more precisely adjust the sand output, thereby allowing the sand jar to better meet the treatment needs of complex conditions.

[0023] Furthermore, the sand storage tank for the dental air-blasting cleaning equipment also includes a one-way duckbill valve 13, which connects the valve mounting member 14 and the sand-drawing chamber 16 and is located between the valve mounting member 14 and the sand-drawing chamber 16.

[0024] In this embodiment, the one-way duckbill valve 13 can prevent sand powder from flowing back into the equipment that provides compressed gas, thus avoiding damage to the equipment.

[0025] Furthermore, the sand tank for the dental air-blasting cleaning equipment also includes an air inlet pipe 20, which passes through the valve mounting member 14 and is detachably connected to the one-way duckbill valve 13, and is located at the center of the valve mounting member 14.

[0026] In this embodiment, the air inlet pipe 20 facilitates the supply of compressed gas to the sand tank by a device that provides compressed gas.

[0027] Furthermore, the sand storage tank for the dental air polishing equipment also includes a first sealing ring 9, a second sealing ring 10, a third sealing ring 11, and a fourth sealing ring 12. The first sealing ring 9 is fitted inside the knob 1 and located at the connection between the knob 1 and the sand cover 3. The second sealing ring 10 is fitted inside the sand cover 3 and located at the top of the inner tank 6. The third sealing ring 11 is fitted on the outer surface of the valve mounting part 14 and located inside the connecting cavity 19. The fourth sealing ring is fitted on the outer surface of the guide block 2 and located at the bottom of the sand cover 3.

[0028] In this embodiment, the first sealing ring 9 is used to seal the sand cover 3, the second sealing ring 10 is used to seal the top of the inner tank 6, the third sealing ring 11 is used to seal the valve mounting part 14, and the fourth sealing ring 12 is used to seal the guide block 2, thereby ensuring the overall airtightness of the sand tank during operation, ensuring operational stability and safety. The fourth sealing ring 12 also cooperates with the sand cover 3 to limit the rotation angle of the knob 1, preventing the user from excessively rotating the knob 1 and improving the user experience.

[0029] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
