Description

[0002] At present, the main methods used in clinical tooth cleaning include manual scaling, ultrasonic cleaning and sandblasting, which are mainly used to remove tartar, plaque, tea stains, cigarette stains, etc. attached to the tooth surface.

[0003] The principle of sandblasting is to use high-speed gas flow to drive the tooth cleaning powder to form a particle flow, which acts on the tooth surface through a tiny nozzle and uses the kinetic energy of the particle flow to remove tartar and plaque on the tooth surface.

[0004] In the existing sandblasting device, at the outlet end of the sandblasting handle, the distance between the water system and the air system is small. Therefore, during operation, cleaning water and air powder are easily in contact, causing the air powder to agglomerate and block the nozzle opening. At the end of the work, water in the water system is easy to flow back to the outlet of the air powder and contact with the tooth cleaning powder, causing the air powder to agglomerate and block the nozzle opening, affecting the subsequent use of the nozzle. At the same time, it takes a lot of energy to clean the nozzle, affecting the overall use effect of the equipment. Summary of the invention

[0030] See also Figure 1 As shown, an anti-clogging tooth cleaning sandblasting device includes a water-gas joint 1, a control chip 2, a sandblasting handle 3, a water system 4, an air system 5, a first solenoid valve 6, a powder bottle 7 and a first air pump 8. The water outlet of the water-gas joint 1 is connected to the water inlet of the sandblasting handle 3 through the water system 4.

[0031] The air outlet end of the water-gas joint 1 is communicated with the feed end of the powder bottle 7 through the air path system 5 , and the discharge end of the powder bottle 7 is communicated with the air inlet of the sandblasting handle 3 .

[0032] The air outlet end of the water-gas joint 1 is communicated with one end of the first solenoid valve 6 through the air path system 5 , and the other end of the first solenoid valve 6 is communicated with the air inlet of the sandblasting handle 3 through the air path system 5 .

[0033] The first solenoid valve 6 is electrically connected to the control chip 2 .

[0034] The air outlet end of the first air pump 8 is communicated with the air inlet of the sandblasting handle 3 .

[0035] The first solenoid valve 6 cooperates with the air circuit system 5 to use compressed air to discharge the residual tooth cleaning powder in the air circuit system 5 when the machine is shut down; the first air pump 8 cooperates with the air circuit system 5 to work in stages to generate clean airflow and continue to clean the residual water vapor in the pipeline.

[0036] The staged operation here refers to a working mode in which the first air pump 8 works for 30 seconds and stops for 10 minutes. This working mode can continuously and intermittently spray air to the pipeline, sandblasting handle and nozzle to prevent powder blockage.

[0037] With this structure, the cleaning water injected from the outside enters the water system 4 through the water-gas joint 1, and is sprayed out through the end of the sandblasting handle 3 through the water system 4, and the compressed air enters the air system 5 through the water-gas joint 1, and the compressed air is mixed with the tooth powder in the powder bottle 7 according to a predetermined ratio, and the mixed gas powder is sprayed out through the outlet end of the sandblasting handle 3, and the mixed gas powder is secondary mixed and atomized with the cleaning water at the outlet end of the sandblasting handle 3, and finally sprayed onto the tooth surface to clean the dirt and stains on the teeth, and at the same time polish and massage the tooth glaze.

[0038] When exiting the working state, the water system 4 and the air system 5 are closed at the same time, that is, the water system 4 no longer delivers clean water, and the air system 5 no longer delivers mixed gas and powder. At this time, the first solenoid valve 6, under the drive of the control chip 2, works for a short period of time, and uses the high-pressure gas in the air system 5 to clean the sandblasting handle 3 and the rear section of the air system 5, so as to prevent the water of the water system 4 from entering the sandblasting handle 3 from the outlet end of the sandblasting handle 3, and to prevent the clean water from staying at the outlet end of the sandblasting handle 3 and contacting the tooth powder, causing the tooth powder to clump and block the sandblasting handle 3.

[0039] Preferably, the water system 4 includes a water hose 41 and a second solenoid valve 42, the water outlet end of the water-gas connector 1 is connected to one end of the second solenoid valve 42 through the water hose 41, and the other end of the second solenoid valve 42 is connected to the water inlet of the sandblasting handle 3 through the water hose 41; the second solenoid valve 42 is electrically connected to the control chip 2.

[0040] With this structure, through the cooperation between the water hose 41 and the second solenoid valve 42 , the control chip 2 sends a signal to the second solenoid valve 42 to control the opening or closing of the second solenoid valve 42 , thereby controlling the working state of the water system 4 .

[0041] Meanwhile, the water system 4 further comprises a water breathing tank 43 , which is arranged on a water hose 41 between the second solenoid valve 42 and the sandblasting handle 3 , and is connected to the corresponding water hose 41 .

[0042] With this structure, when the work stops, the first solenoid valve 6 opens, and the high-pressure gas in the air circuit system 5 is ejected from the sandblasting handle 3, which plays the role of cleaning the sandblasting handle 3. At the same time, due to the gas flow rate, a negative pressure is formed at the water breathing tank 43, and the negative pressure value is about 5kpa to 15kpa. Under the action of atmospheric pressure, the shape and volume of the water breathing tank 43 are compressed to a certain extent. When the first solenoid valve 6 is closed, the water breathing tank 43 recovers under the action of its own elastic deformation, and the clean water remaining in the water circuit hose 41 between the second solenoid valve 42 and the sandblasting handle 3 is sucked back into the water breathing tank 43, effectively avoiding the contact between the clean water and the gas powder, and having a good anti-clogging effect.

[0043] Specifically, the air circuit system 5 includes an air circuit hose 51 and a third solenoid valve 52. The air outlet end of the water-gas connector 1 is connected to one end of the third solenoid valve 52 through the air circuit hose 51, and the other end of the third solenoid valve 52 is connected to the feeding end of the powder bottle 7 through the air circuit hose 51. The discharge end of the powder bottle 7 is connected to the air inlet of the sandblasting handle 3 through the air circuit hose 51; the third solenoid valve 52 is electrically connected to the control chip 2.

[0044] With this structure, the control chip 2 sends a signal to the third solenoid valve 52 through the cooperation between the air circuit hose 51 and the third solenoid valve 52 to control the opening or closing of the third solenoid valve 52, thereby controlling the working state of the air circuit system 5.

[0045] After the water breathing tank 43 sucks back the clean water in the water hose 41, the first air pump 8 starts to work to intermittently and periodically clean and maintain the sandblasting handle 3 and related pipelines, so that the air pipe and water pipe at the outlet end of the sandblasting handle 3 will not be scaled or blocked.

[0046] Specifically, it also includes a pressure switch 9 , a detection end of the pressure switch 9 is connected to the water-gas connector 1 , and an output end of the pressure switch 9 is electrically connected to the control chip 2 .

[0047] The air pressure of the water-gas joint 1 is detected by the pressure switch 9. When the preset pressure is reached and the external compressed air pressure is greater than 0.15Mpa, the pressure switch 9 is opened and the system maintains sufficient pressure. At this time, the second solenoid valve 42 and the third solenoid valve 52 are opened to start the sandblasting and tooth cleaning work.

[0048] Meanwhile, a foot switch 10 is also included. The foot switch 10 is arranged on the side of the dental chair, and the output end of the foot switch 10 is electrically connected to the control chip 2 .

[0049] When in use, the input of compressed air can be turned on or off by the foot switch 10, thereby playing a control role.

[0050] In this embodiment, a powder bottle identification module 11 is further included, and the powder bottle identification module 11 is used to detect whether a powder bottle is installed.

[0051] In this embodiment, the powder bottle 7 has a capacity of 50 ml and is expected to hold 25 g of tooth powder. By detecting whether the powder bottle 7 is installed, the system determines whether to enter the working mode.

[0052] Preferably, it also includes a power conversion module 12 for converting the mains power into the working voltage of the control chip 2 of the sandblasting device.

[0053] The power conversion module 12 is used to convert the voltage from AC mains power to DC voltage to supply power to the electrical components in the device to avoid circuit damage.

[0055] Preparation stage: compressed air reaches the preset pressure value;

[0056] Identify tooth powder bottle: Identify whether the powder bottle is installed;

[0057] Teeth cleaning stage: turn on the water system and air system, mix tooth powder and clean water, and clean the teeth through the sandblasting handle;
