[0038] Dental sandblasting is a type of air polishing technology that uses compressed gas (usually air) to lift sand powder and spray it onto the tooth surface, and then combine it with the sprayed liquid medium (usually water) to clean the tooth surface. Specifically, it can remove plaque, soft scale, smoke stains, and tea stains on the tooth surface, which can effectively prevent periodontal disease and maintain dental health. Dental clinics generally require a compressor room to provide a large flow of high-pressure positive or negative pressure to the dental chair, so that the dental chair can spray liquid and sand powder at high pressure to sandblast the teeth. Therefore, the sandblasting equipment requires a large floor space and is costly, and cannot be used as a miniaturized household device for daily cleaning.

[0039] As people's living standards improve, they pay more and more attention to their oral health. It is necessary to research and develop a household sandblasting teeth cleaning device with simple structure and easy operation to meet the needs of home users for oral cleaning and care at home.

[0040] In view of the above problems, the present application provides a sandblasting tooth cleaning device 100, please refer to Figures 1 to 3 , provides a sandblasting tooth cleaning device 100 including a main unit 110, a nozzle assembly 120, an air circuit system 130 and a liquid circuit system 140, wherein the main unit 110 is connected to the nozzle assembly 120 via the air circuit system 130 and the liquid circuit system 140; the main unit 110 includes a powder bin 111 for holding tooth cleaning powder and a water storage bin 112 for holding water, the air circuit system 130 is used to spray the tooth cleaning powder in the powder bin 111 from the nozzle assembly 120, and the liquid circuit system 140 is used to spray the water in the water storage bin 112 from the nozzle assembly 120.

[0041] like Figures 1 to 3 As shown, the host 110 is used to control the operation and stop of the sandblasting and tooth cleaning device 100, and the nozzle assembly 120 is used to operate and act on the human body. The host 110 includes a chassis, on which a water storage tank 112 and a powder tank 111 are provided. The chassis is provided with an air circuit system 130 that generates high-speed flow of gas to drive the tooth cleaning powder from the nozzle assembly 120 to spray onto the teeth, and a liquid circuit system 140 that transports liquid to the nozzle assembly 120. Among them, when the sandblasting and tooth cleaning device 100 is in the tooth cleaning mode, the liquid transported by the liquid circuit system 140 and the tooth cleaning powder driven by the air circuit system 130 are sprayed out from the nozzle assembly 120 at the same time.

[0042] Of course, the user can also switch the sandblasting tooth cleaning device 100 to the cleaning mode as needed when only rinsing the mouth or washing the tooth surface with water. The host 110 only controls the liquid circuit system 140 to open, so that the nozzle assembly 120 can only spray water or water mist to act on the user's mouth.

[0043] The powder bin 111 and the water storage bin 112 are detachably connected to the main unit 110, and the user can remove the powder bin 111 and / or the water storage bin 112 from the main unit to replenish the tooth cleaning powder and / or water source for the sandblasting and tooth cleaning device 100. Specifically, the powder bin 111 and the water storage bin 112 can be separated from the main unit 110 by pulling, which is more convenient for the user to disassemble and install. Of course, other methods such as card unlocking can also be used, which are not limited here.

[0044] The sandblasting and tooth cleaning device 100 of the embodiment of the present application is compact and simple in structure by arranging a water storage tank 112 and tooth cleaning powder on a main unit 110, arranging an air circuit system 130 and a liquid circuit system 140 in a chassis of the main unit 110, and placing a nozzle assembly 120 outside the chassis of the main unit 110 and connecting the main unit 110 with a connecting line. The large-scale sandblasting and tooth cleaning devices on the market can be miniaturized and made home-friendly, thus meeting people's daily oral cleaning needs.

[0045] The connection line between the nozzle assembly 120 and the host 110 can be a rope or line with elastic force and adjustable length to adjust the distance between the nozzle assembly 120 and the host 110, so as to be suitable for hand-held operation by users of various heights, and make the placement of the sandblasting and cleaning device 100 more flexible and more practical. The performance and use effect of the sandblasting and cleaning device 100 of the present application can achieve the effect of sandblasting and cleaning teeth once in a dentist's clinic by ensuring a certain frequency of use within a certain period of time.

[0046] In the present application, please refer to Figure 1 , Figure 2 and Figure 4 The air circuit system 130 includes an air pump 132, a first air circuit pipeline 132 and a second air circuit pipeline 134. One end of the first air circuit pipeline 132 is connected to the air pump 132, and the other end is connected to the nozzle assembly 120 through the powder bin 111; one end of the second air circuit pipeline 134 is connected to the air pump 132, and the other end is connected to the nozzle assembly 120.

[0047] The housing of the host 110 is a sealed structure. External air enters the housing through the air inlet of the air pump 132 in the air system 130, and the air is compressed by the air pump 132 to generate air pressure and form high-pressure gas in the housing. The air outlet of the air pump 132 delivers high-pressure gas to the first air pipeline 132 and the second air pipeline 134. The high-pressure gas passes through the powder bin 111 in the first air pipeline 132, drives the tooth cleaning powder in the powder bin 111 to the nozzle assembly 120 and sprays out from the nozzle assembly 120. The high-pressure gas is directly sprayed from the nozzle assembly 120 in the second air pipeline 134. The additional provision of an air pipeline, namely the second air pipeline 134, can realize the self-cleaning mode of the nozzle assembly 120. When the nozzle assembly 120 does not need to spray tooth cleaning powder, gas is only sprayed from the nozzle assembly 120, so as to clean the nozzle assembly 120 to prevent tooth cleaning powder from remaining in the spray port, causing the spray port to be blocked, and inconvenient for the subsequent use of the sandblasting and tooth cleaning device 100.

[0048] The embodiment of the present application replaces the large compressor of the existing sandblasting and tooth cleaning device 100 with an air pump 132, so that the sandblasting and tooth cleaning device 100 of the present application can achieve the effect of people cleaning and sandblasting their teeth at home. Although the gas generated by the air pump 132 cannot be compared with the gas pressure and gas volume that can be generated by a large compressor, and the performance and effect of the sandblasting and tooth cleaning device in the dental clinic on the market are slightly different, the sandblasting and tooth cleaning device 100 of the present application has a compact and integrated structure and is easy to operate. The frequency of sandblasting and tooth cleaning of the oral cavity by the user will increase. If a certain frequency of use is guaranteed within a certain period of time, the effect of sandblasting and tooth cleaning treatment at a dental clinic can still be achieved, and it is more cost-effective.

[0049] Specifically, an injection pipe 136 is provided between the nozzle assembly 120 and the gas circuit system 130, and the first gas circuit pipe 132 and the second gas circuit pipe 134 in the gas circuit system 130 are both connected to the injection pipe 136. Figure 4 As shown, the two air pipelines finally form an air jet pipeline 136. On the one hand, such a configuration takes into account that the nozzle assembly 120 needs to be held by the user, and multiple air pipelines are connected to the nozzle assembly 120, which will make the external structure of the nozzle assembly 120 too large, which is not conducive to the user's hand-held operation; on the other hand, combined with the above-mentioned sandblasting and tooth cleaning device 100 in the self-cleaning mode, the second air pipeline 134 is used to simply spray air to the air jet pipeline 136, which can spray the tooth cleaning powder remaining on the tube wall of the air jet pipeline 136 from the nozzle assembly 120, further avoiding blockage, ensuring the cleaning effect of the sandblasting and tooth cleaning device 100, and improving durability.

[0050] More specifically, a controller 113 is provided in the host 110, the first air pipeline 132 includes a first solenoid valve 133, the second air pipeline 134 includes a second solenoid valve 135, and the first solenoid valve 133 and the second solenoid valve 135 are connected to the air outlet of the air pump 132; the controller 113 is used to control the opening or closing of the first solenoid valve 133 and the second solenoid valve 135.

[0051] In order to realize that the nozzle assembly 120 can simultaneously spray water and tooth cleaning powder into the human mouth to realize the tooth cleaning mode, only spray water into the human mouth to realize the cleaning mode, and only spray gas to the outside to realize the self-cleaning mode, a controller 113 and multiple solenoid valves are provided in the main unit 110. The controller 113 controls different solenoid valves to open according to different working modes of the sandblasting tooth cleaning device 100 to realize the functions in each working mode.

[0052] The first solenoid valve 133 is connected to the first air pipeline 132, the second solenoid valve 135 is connected to the second air pipeline 134, and the liquid circuit system 140 includes a liquid pump, which is connected to the controller 113; when the sandblasting and tooth cleaning device 100 is in the tooth cleaning mode, the controller 113 controls the first solenoid valve 133 to open and controls the liquid pump to start; when the sandblasting and tooth cleaning device 100 is in the cleaning mode, the controller 113 only controls the liquid pump to start, and the first solenoid valve 133 and the second solenoid valve 135 are closed; when the sandblasting and tooth cleaning device 100 is in the self-cleaning mode, the controller 113 controls the second solenoid valve 135 to open and the first solenoid valve 133 to close.

[0053] In the embodiment of the present application, the solenoid valve can be normally open or normally closed. Preferably, the controller 113 can use PCB (Printed Circuit Board) or FPC (Flexible Printed Circuit board) to make the components of the sandblasting and tooth cleaning equipment 100 more cost-effective and have a more compact structure, which is more convenient for daily home use.

[0054] The present application is an embodiment. When the sandblasting and tooth cleaning device 100 is in operation, the controller 113 first controls the second solenoid valve 135 to open, and after the second solenoid valve 135 is opened for a period of time, controls the second solenoid valve 135 to close, and then controls the first solenoid valve 133 to open. When the sandblasting and tooth cleaning device 100 is in the tooth cleaning mode, the controller 113 will first open the second solenoid valve 135, and the high-pressure gas will sequentially flow from the second gas pipeline 134 and the jet pipeline 136 to the nozzle assembly 120 and spray outward, blowing out the powder or dirt on the jet pipeline 136 and the nozzle assembly 120 in advance; after 3-5s, the controller 113 controls the solenoid valve to close, and opens the first solenoid valve 133, and controls the operation of the liquid system 140 at the same time. At this time, the high-pressure gas passes through the first gas pipeline 132, the powder bin 111, and the jet pipeline 136 in sequence to reach the nozzle assembly 120, and the high-pressure gas drives the tooth cleaning powder in the powder bin 111 to reach the nozzle assembly 120 and spray outward when passing through the powder bin 111. Cleaning the jet pipe 136 and the jet port in advance can prevent the liquid and the tooth cleaning powder from mixing and agglomerating to cause the nozzle assembly 120 to be blocked, thereby ensuring the stable performance of the sandblasting tooth cleaning device.

[0055] Furthermore, when the sandblasting and tooth cleaning device 100 stops the tooth cleaning mode, the controller 113 first controls the first electromagnetic valve 133 to close, and after the first electromagnetic valve 133 is closed, controls the second electromagnetic valve 135 to open, and closes after 3-5 seconds. That is, after the nozzle assembly 120 stops spraying tooth cleaning powder, the controller 113 will open the second air pipeline 134 to spray air to the air jet pipeline 136 to prevent the air jet pipeline 136 or the nozzle assembly 120 from having tooth cleaning powder that has not been sprayed out in time, and to prevent the liquid from flowing back after the liquid system 140 stops operating, so that the sandblasting and tooth cleaning device 100 is hygienic and safe, and has good anti-blocking performance.

[0056] In order to make the sandblasting and tooth cleaning device 100 in the embodiment of the present application more compact and easier to control, the liquid pump in the liquid circuit system 140 of the present application can also be the air pump 132 of the above-mentioned air circuit system 130. By using an air pump 132 as a power element, the high-pressure airflow output by the air pump 132 is divided into two. In the tooth cleaning mode, high-pressure gas is simultaneously delivered to the liquid circuit pipeline in the liquid circuit system 140 and the first air circuit pipeline 132 and the second air circuit pipeline 134 in the air circuit system 130 to spray the liquid sealed in the water storage tank 112 and the gas in the powder tank 111 from the nozzle assembly 120.

[0057] In the present application, continue to refer to Figure 3The air circuit system 130 further includes an air drying device 137, which is used to dry the air compressed by the air pump 132. The air drying device 137 is arranged between the air pump 132 and the first air circuit pipeline 132 and the second air circuit pipeline 134. The air drying device 137 can separate the moisture in the external air entering the chassis of the host 110 through the air inlet of the air pump 132, so that the air circuit system 130 is in a dry environment, and the gas with water vapor enters the first air circuit pipeline 132 and contacts the toothpaste in the powder bin 111, causing the first air circuit pipeline 132 to be blocked.

[0058] In the present application, please refer to Figures 5 to 7 Combined with Figure 1 The nozzle assembly 120 includes a nozzle body 121 and a nozzle 122, and the nozzle 122 is detachably connected to the nozzle body 121. The tooth cleaning powder and water are sprayed out from the nozzle 122, and the opening of the nozzle 122 is usually very small, so as to better control the pressure and flow of the nozzle assembly 120, and to spray more concentratedly on a certain area on the teeth, thereby improving the cleaning efficiency and effect. However, the nozzle 122 is easily blocked. Although the above embodiments provide a variety of anti-blocking implementation methods of the sandblasting and tooth cleaning device 100 of the present application, in order to prevent the nozzle 122 from being blocked and causing the device to fail to work or be damaged, the nozzle 122 is detachably connected to the nozzle body 121. After the sandblasting and tooth cleaning device 100 has been used for a period of time, the user can replace the new nozzle 122 for use, thereby extending the service life of the sandblasting and tooth cleaning device 100 of the present application and reducing maintenance costs. In addition, the replaceable setting of the nozzle 122 improves the functional diversity and flexibility of the sandblasting and cleaning device 100. Different nozzles 122 can be replaced to achieve different types of cleaning. For example, some nozzles 122 are more suitable for cleaning the tooth surface, and some are more suitable for cleaning the gaps between teeth and the pits and fissures of teeth.

[0059] In the present application embodiment, Figure 1 and Figure 7 As shown, the nozzle 122 is provided with an air jet 124 and a liquid jet 123, and the liquid jet 123 is arranged around the air jet 124. Liquid and toothpaste are sprayed from different air jets, the air jet 124 is located at the center of the nozzle 122, and the liquid jet 123 is arranged around the air jet 124, so that the liquid can wrap the toothpaste and better mix with the toothpaste to act on the teeth, and the toothpaste can be prevented from splashing, thereby avoiding the impact on the eyes and respiratory tract of the user.

[0060] Furthermore, if Figures 4 to 7 As shown, the gas circuit system 130 is connected to the air jet port 124, and the liquid circuit system 140 is connected to the liquid jet port 123. The gas circuit system 130 and the liquid circuit system 140 are independently arranged.

[0061] Therefore, when the sandblasting tooth cleaning device 100 is working, the water flows through the liquid path system 140 and then is sprayed out from the liquid spray port 123, and the tooth cleaning powder is driven by the pressurized gas provided by the air pump 132 and passes through the air path system 130 and the jet pipe 136 in sequence and then is sprayed out from the jet port 124. The liquid path system 140 and the air path system 130 are independent of each other and are not connected to each other, so that the tooth cleaning powder and the liquid are isolated until they are sprayed out from the jet port 124 and the liquid spray port 123 respectively and then they can converge on the tooth surface, thereby avoiding the blockage of the tooth cleaning powder in the nozzle body 121 due to the water solubility of the tooth cleaning powder.

[0062] like Figure 6 As shown, the nozzle assembly 120 also includes a gasket 125, which is sleeved on the nozzle 122 and is used to contact human teeth. The gasket 125 is arranged around the outer edge of the nozzle 122. The contact with human teeth through the gasket 125 has a certain buffer compared to directly acting on the teeth through the nozzle 122, which can avoid the damage of the gums by the tooth cleaning powder particles during the tooth cleaning or treatment process, and can make the user have a certain psychological expectation, which is safer. In addition, the gasket 125 covers and protrudes from the nozzle 122, which can further prevent the tooth cleaning powder from splashing. In the embodiment of the present application, the gasket 125 can be a soft skin-friendly material such as silicone, resin, rubber, etc.

[0063] Please continue to refer to Figures 4 to 7 The height of the gasket 125 is 18-22 mm (millimeter), and the width of the gasket 125 is 8-12 mm.

[0064] In the embodiment of the present application, the shape of the gasket 125 is adapted to the shape of human teeth. Considering the length and width of adult teeth, the size of the gasket 125 is set according to the size of adult teeth. The height of the gasket 125 is the height of one tooth, and the width is about the width of two teeth. When sandblasting teeth cleaning is required, the nozzle assembly 120 with the gasket 125 is directly placed on the teeth to be cleaned and covers the teeth. The gasket 125 is set in this way to limit the teeth well, and its size is adapted to human teeth, so that the teeth to be cleaned can be quickly and accurately positioned, and the operation is more convenient. The fool-style operation enhances the user experience.

[0065] The tooth cleaning powder, i.e., sand powder, in the embodiment of the present application is solid particles, and its ingredients are usually sodium bicarbonate, glycine, erythritol, etc. (the main ingredients of sand powder are sodium bicarbonate, glycine, erythritol, etc., which are safe and harmless and are edible grade. At the same time, its hardness is much smaller than the hardness of tooth enamel and does not damage teeth). Its particle size is usually 14μm (micrometre) to 90μm, and its hardness is usually Mohs hardness 2-2.5. Therefore, when the sand powder is accelerated to a high-speed state and mechanically rubs against the teeth, it can achieve complete removal of residues, dental plaque, and pigments, thereby achieving thorough oral cleaning.

[0066] It should be noted that the specific structure of the sandblasting tooth cleaning device of the present application can also be applied to any equipment that needs to spray water / cleaning liquid and cleaning powder, such as sweepers, floor scrubbers, shoe washing equipment, etc.

[0067] The above is only a preferred embodiment of the present application, and does not constitute any formal limitation on the present application. The protection scope of the present application shall be subject to the protection scope of the claims. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content disclosed above without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are within the scope of the technical solution of the present application.
